Description

PIPE HANDLING APPARATUS

Field of the Invention

The present invention relates to pipe handling apparatus for use in inserting a pipe into, or releasing a pipe from, a pipe connector element; in particular to a pipe handling tool and a pipe chamfering tool.

Background to the Invention

Pipe connectors and methods for connecting pipes therewith are known. A problem exists in that traditional manual methods of connecting a pipe into a pipe connector element may result in an insufficient connection. It is known that good compression is required to push a pipe into a pipe connector element to create a satisfactory connection; however, it is not always possible to achieve an adequate fit. It is found that this is typically due to an inability to achieve sufficient grip and/or movement by hand. This difficulty may be increased due to poor or awkward access to the connection area. Further, the condition of the end of the pipe being connected may result in fouling on entry into a pipe connector element. In some instances, it is found that performing disconnection of a pipe from a pipe connector element may be problematic, again due to issues with achieving sufficient grip and/or movement by hand.

Detailed Description

There will now be described by way of example a specific mode contemplated by the inventors. In the following description numerous specific details are set forth in order to provide a thorough understanding. It will be apparent however, to one skilled in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to

unnecessarily obscure the description.

Figure 1 Figure 1 shows a pipe handling tool 101. The pipe handling tool 101 is usable by an operative 102 for inserting a pipe into, or releasing a pipe from, a pipe connector element. Thus, for example, the pipe handling tool 101 may be used to facilitate connection of pipe section 103 within pipe connector element 104.

It is known that good compression is required to push a pipe into a pipe connector element to create a satisfactory connection; however, it is not always possible to achieve an adequate fit. It is found that this is typically due to an *.S.

inability to achieve sufficient grip and/or movement by hand. This difficulty may **....

be increased due to poor or awkward access to the connection area. Further, the :. condition of the end of the pipe being connected may result in fouling on entry * *: into a pipe connector element. In some instances, it is found that performing disconnection of a pipe from a pipe connector element may be problematic, again due to issues with achieving sufficient grip and/or movement by hand.

As will be described in further detail below, a pipe handling tool is configured to be located about a pipe connector element, to grip a pipe, and then to drive the gripped pipe relative to the pipe connector element. As will further be described in detail below, a pipe chamfering tool is configured to be located relative to the end of a pipe and rotated to trim the end of the pipe.

Figure 2 Pipe handling tool 101 is shown in Figure 2 in further detail. The pipe handling tool 101 comprises a frame member 201, a pipe support element 202 providing a shoulder 203 at a first location, and a pipe drive mechanism, indicated generally at 204. The pipe drive mechanism 204 comprises a first pipe gripping element 205 presenting a first pipe gripping surface 206, and a second pipe gripping element 207 presenting a second pipe gripping surface 208. A pipe gripping region is defined between the first pipe gripping surface 206 and the second pipe gripping surface 208 at a second location that is spaced apart from the first location. As will be described in further detail below, the pipe handling tool 101 is configured to receive a pipe longitudinally such that a received pipe is supported by the pipe support element 202 and is gripped between the first pipe gripping surface 206 and the second pipe gripping surface 208 of the pipe drive mechanism 204. The pipe drive mechanism 204 is configured, in response to operation thereof, to drive a received pipe in a longitudinal direction, whereby the received pipe is urged towards or away from the shoulder 203 of the pipe support element 202 by operation of the pipe drive mechanism 204. In this embodiment, the first pipe gripping surface 206 and the second pipe gripping surface 208 are **.. 25 configured to grip a pipe received therebetween by means of friction.

As will be described in further detail below, the first pipe gripping element 205 and the second pipe gripping element 207 are each rotatably mounted to the * * frame member 201. The first pipe gripping element 205 comprises a first toothed S..

gear portion 209 and the second pipe gripping element 207 comprises a second toothed gear portion 210. The first and second pipe gripping elements 205, 207 are arranged such that the first and second toothed gear portions 209, 210 mesh together. According to this illustrated example, the pipe drive mechanism comprises a first handle 211 that extends from the frame element 201 and a second handle 212 that extends from the second pipe gripping element 207, and the pipe drive mechanism is operated by moving the second handle 212 relative to the first handle 211. According to this embodiment, the pipe drive mechanism is manually operable. It is to be appreciated however that the pipe drive mechanism may be driven by supplementary apparatus operatively connected thereto.

To facilitate use and operation of the pipe gripping tool, the recess 213 of the pipe support element 202 may be profiled to complement the shape of a pipe.

For example, in this illustrated example, recess 213 of the pipe support element 202 defines a generally "U" shaped as to support a substantially circular pipe at an appropriate height. It is to be appreciated however that the recess 213 of the pipe support element 202 may have an alternative shape or may be configurable to accommodate different cross-sectional shapes of pipe.

As previously mentioned, the pipe handling tool of this embodiment has a first pipe gripping surface 206 and a second pipe gripping surface 208, which are configured to grip a pipe received therebetween by means of friction.

As shown in Figure 2, the pipe gripping tool 101 may be provided with a first pipe gripping element sleeve 214 and a second pipe gripping element sleeve 215 for location over the first pipe gripping element 205 and the second pipe gripping element 207 respectively. In an embodiment, the pipe gripping element sleeves 214, 215 are releasably securable over the pipe gripping elements 205, 207. In an example, each pipe gripping element sleeves 214, 215 is locatable * over either pipe gripping element 205, 207. In an example, the pipe gripping element sleeves are configured to be located over the pipe gripping elements by :. a push-fit action. The pipe gripping sleeves may be used to vary one or * * characteristics of the pair of gripping surfaces presented by the pipe handling tool. In this example, the pipe gripping element sleeves 214, 215 present a 3D smoother gripping surface and the ridged gripping surface presented by the gripping elements 205, 207.

The pipe handling tool, and components thereof, may be fabricated from any suitable material or combination of materals. In an example, the fabrication of the pipe handling tool may comprise any one or more of: a metal, aluminium, a plastics material, a thermoplastic elastomer material, glass-reinforced nylon.

In an embodiment comprising a pipe handling tool and a pair of pipe gripping element sleeves, the material fabrication of the pipe gripping element sleeves differs from the material fabrication of the pipe gripping elements. In an example, the pipe gripping element sleeves are fabricated from rubber and the remainder of the pipe tool element is fabricated from metal. In such an example, the pipe gripping element sleeves may be releasably securable over the pipe gripping elements by means of friction.

The pipe handling tool, and components thereof, may be manufactured by any technique or combination of techniques. The manufacture of the pipe handling tool may comprise any one or more of: a die-casting process, a forging process, a moulding process, a dip-coating process.

Figure 3 Features of the first and second pipe gripping elements of the pipe drive mechanism of pipe handling tool 101 are shown in further detail in Figure 3.

As previously described, the first pipe gripping element 205 and the second pipe gripping element 207 are each rotatably mounted to the frame member 201. The first pipe gripping element 205 comprises a first toothed gear portion 209 and the second pipe gripping element 207 comprises a second toothed gear portion 210. The first and second pipe gripping elements 205, 207 are arranged such that the first and second toothed gear portions 209, 210 mesh together. A pipe 301 received by the pipe handling tool extends longitudinally :. therethrough, and is gripped by, the first pipe gripping surface 206 of the first pipe * .: gripping element 205 and the second pipe gripping surface 208 of the second pipe gripping element 207. According to this illustrated arrangement, the first and second pipe gripping surfaces 206, 208 are elevated and recessed with respect to the respective meshing surfaces of the first and second toothed gear portions 209, 210 of the first and second pipe gripping elements 205, 207. The received pipe 301 may rest upon the first and second toothed gear portions 209, 210.

As shown, in this example, the first and second toothed gear portions 209, 210 are each configured as a portion of a spur-gear. Similarly, and as shown, in this example the first and second pipe gripping surfaces 206, 208 are each configured as portions of a spur-gear. According to this embodiment, the surfaces of the first and second pipe gripping surfaces 206, 208 are fixed relative to the surfaces of the first and second toothed gear portions 209, 210. The surfaces of the first and second pipe gripping surfaces 206, 208 are configured to rotate simultaneously with the first and second pipe gripping elements 205, 207.

As can be seen in Figure 3, the surfaces of the first and second pipe gripping surfaces 206, 208 are generally arcuate, in a similar manner to the surfaces of the first and second toothed gear portions 209, 210.

A pipe connector element 302 is received by the pipe handling tool such that a collar 303 of the pipe connector element 302 is located between the first location of the shoulder 203 of the pipe support element 202 and the second location of the pipe gripping region between the first and second pipe gripping surfaces 206, 208. In this Figure, the collar 303 of the pipe connector element 302 is shown in abutment against the shoulder 203 of the pipe support element 202.

The first pipe gripping element 205 is configured to rotate about a first pivot point 304 and the second pipe gripping element 207 is configured to rotate about a second pivot point 305. As previously stated, in this embodiment, a second handle 212 extends from the second pipe gripping element 207. The S...

pipe drive mechanism is operated by moving the second handle 212. Thus, the pipe drive mechanism is responsive to rotation of the second handle 212, in a direction as indicated by arrow 306, about second pivot point 305. Rotation of * the second pipe gripping element 207 causes rotation of the first pipe gripping S..

element 205, by means of the meshing first and second toothed gear portions 209, 210 of the first and second pipe gripping elements 205, 207. Rotation of the first and second pipe gripping elements 205, 207 translates into linear motion of received pipe 301 in a direction indicated by arrow 307.

In an embodiment, the pipe handling tool is configured to drive a received pipe in a single direction only. In an alternative embodiment, the pipe handling tool is configured to allow a received pipe to be driven in either of opposite directions. It is to be appreciated that piping may be configured such that a pipe is engaged within a pipe connector element by a positive mechanical fit that functions to prevent release of the pipe following insertion of the pipe intc the pipe connector element and connection therewith.

In this embodiment, the pipe gripping elements 205, 207 are configured to rotate between first and second extreme positions of movement. The first and second pipe gripping elements 205, 207 are configured to rotate between a maximum receiving configuration and a maximum drive configuration. With reference to use of the pipe handling tool to drive a pipe in the direction of arrow 308 the first and second pipe gripping elements 205, 207 are shown in this Figure in the maximum drive configuration, in which no further degree of rotation is available to drive a received pipe in the direction of arrow 308 towards the shoulder 203 of the pipe support element 202 and into the pipe connector element 302. However, with reference to use of the pipe handling tool to drive a pipe in the opposite direction indicated by arrow 309, the first and second pipe gripping elements 205, 207 are shown in this Figure in the maximum receiving configuration, in which the maximum degree of rotation is available to drive a received pipe in the direction of arrow 309 away from the shoulder 203 of the pipe support element 202 and out of the pipe connector element 302. *I*

The pipe gripping tool may be configured such that the pipe gripping elements 205, 207 are biased towards an extreme position of movement.

According to this present embodiment, the second handle 212 is resiliently * biased towards the maximum drive configuration of the first and second pipe **.

gripping elements 205, 207 with reference to drive in the direction of arrow 308 towards the shoulder 203 of the pipe support element 202 and into the pipe connector element 302. Thus, pipe handling tool 101 may be perceived as having an at rest' configuration from which the pipe handling tool must be configured into an active' configuration, from which the pipe handling tool will act to return to the at rest' configuration.' Figures 4A, 46, 4C, 40 & 4E Figures 4A-4E illustrate a sequence of steps in the usage of a pipe handling tool as described herein for driving a pipe into a pipe connector element.

In this illustrated sequence, the pipe handling tool is initially arranged to receive a pipe and a pipe connector element, subsequently receives the pipe and pipe connector element and finally drives the pipe into the pipe connector element.

The pipe handling tool 101 is configurable from the at rest' configuration shown in Figure 4A into the active' configuration' shown in Figure 4B by opening the handles 211, 212 apart, for example by moving second handle 212 away from first handle 211 in the direction of rotation indicated by arrow 401. As shown in Figure 4C, the pipe handling tool 101 in the active' configuration' is now configured to receive pipe 301 and pipe connector element 302 into the arrangement shown in Figure 4D. The pipe handling tool 101 is then configurable from the active' configuration shown in Figure 4D into the at rest' configuration' shown in Figure 4E, whilst the pipe 301 and the pipe connector element 302 are received, by closing the handles 211, 212 together, for example by moving second handle 212 towards the first handle 211 in the direction of rotation indicated by arrow 402, which is the opposite direction of rotation to that indicated by arrow 401. As a result of this action, the received pipe 301 is driven into the received pipe connector element 302, in the direction indicated by arrow 403. The pipe handling tool 101 may then be manoeuvred relatively to and released from the connected pipe and pipe connector element arrangement illustrated in Figure 4E.

* The pipe handling tool functions to provide improved grip and movement of a pipe, compared to manual handling.

Figures 5A, 5B, 5C & 5D Figures 5A-5D each shows a pipe chamfering tool having a location member for locating the pipe chamfering tool relative to the end of a pipe. The pipe chamfering tool comprises is configured to be located relative to the end of a pipe and rotated to trim the end of the pipe. The location member serves to maintain the pipe chamfering tool in proper orientation relative to the end of the pipe to facilitate smooth and efficient operation thereof.

A first pipe chamfering tool 501 is shown in Figures 5A and 5B and a second pipe chamfering tool 502 is shown in Figures 5C and 5D, both configured for use with a pipe fabricated from a plastics material and having a circular cross-section.

Both the first pipe chamfering tool 501 and the second pipe chamfering tool 502 have a substantially cylindrical location member extending from a chamfering member comprising a blade. Both the first and second pipe chamfering tools 501, 502 are configured to be located relative to an end of the pipe and rotated with respect to the pipe such that the blade of the chamfering member shaves material from the end of the pipe.

First pipe chamfering tool 501 has an external location member 503 that is configured to be located around a pipe P, as illustrated in Figure 5B, and while so located, to be rotated such that the blade 504 acts on the end of the pipe P. The chamfering member 505 defines an open end 506 to allow for the flow of swan material therefrom. In this example, the external location member 503 presents at least one grip 507, to facilitate purchase of the pipe chamfering tool 501.

Second pipe chamfering tool 502 has an internal location member 508 that is configured to be located inside a pipe P, as illustrated in Figure 50, and 25 while so located, to be rotated such that the blade 509 acts on the end of the pipe. The chamfering member 510 defines an open end 511 to al!ow for the flow of swan therefrom. In this example, the chamfering member 510 presents at least one grip 512, to facilitate purchase of the pipe chamfering tool 502. U..

In an example, a pipe chamfering tool is provided that provides a pipe chamfer trim angle of approximately 15°. The pipe chamfering tool is thus usable to create a bevelled edge from a 90° sharp corner or substantially square corner.

This feature serves to facilitate entry of the pipe end into a pipe connector element.

Figures 6A&6B Pipe handling apparatus comprising a pipe handling tool and a pipe chamfering tool may comprise a pipe handling tool configured to stow the pipe chamfering tool. For example, as shown in Figure 6A, pipe handling tool 101 may define an aperture, indicated at 601. The pipe chamfering toot 602 may also define an aperture, indicated at 603. A connecting member 604 may be used to connect the pipe handling tool 101 and the pipe chamfering tool 602. Thus, as illustrated in Figure 6A, a connecting member 604 may be passed through the apertures 601, 603 of the pipe handling tool 101 and pipe chamfering member 602 respectively and tied to form a securing loop. Alternatively, or additionally, the pipe chamfering tool 602 may be configured to be located within the aperture 601 of the pipe handling tool 101 as shown in Figure 6B, or from the opposite perspective, the aperture 601 of the pipe handhng tool 101 may be configured to receive the pipe chamfering tool 602.

Thus, pipe handling apparatus as described herein that serve to facilitate connection of a pipe with a pipe connector element. Pipe handling apparatus as described herein may also serve to facilitate disconnection of a pipe from a pipe connector element. The pipe handling tool functions to provide increased grip of a pipe. In turn, this allows for easier and steadier movement of a pipe relative to a pipe connector element. It is to be appreciated that a pipe handling tool and/or a pipe chamfering tool as described herein may have any desired aesthetic finish and may present any desired colouration, colourations, graphics and/or alpha-numerical indications.
