Description

Gear disassembly device {Lamp for vehicle}

The present invention relates to a gear disassembly device for valves mainly used in water supply and sewage.

In general, butterfly valves are widely used in water and sewage construction to open and close water and sewage pipes.

As shown in FIG. 1, a conventional butterfly valve for water supply and sewerage has a gear module including a valve housing (1), a worm gear (2), and a worm wheel (10) disposed on one side, A butterfly valve may be provided on the other side to rotate simultaneously with the worm wheel 10.

The gear module has a worm gear (2) provided on the rotation axis of the power unit that provides the same driving force as a motor (not shown), and engages with the worm gear (2) to receive the rotational force of the worm gear (2) and rotate in conjunction with it. A worm wheel 10 is provided.

At this time, while the worm wheel 10 rotates, the butterfly valve using the same rotation axis rotates on the opposite side of the housing 1 to open or close the inside of the water supply and sewage pipe.

Although not shown in the drawing, this gear module may further be provided with a cover that covers the outside of the worm gear 2 and the worm wheel 10, and a lubricant such as grease may be filled between the cover and the housing 1. .

And, the gear module rotates the worm wheel (10) through the driving force generated by the worm gear (2). At this time, since gear drive is performed using a worm and worm gear method, the worm wheel (10) rotates the worm gear (2). There is an advantage that the valve opening due to the water pressure transmitted to the butterfly valve can be prevented by preventing the transmission of driving force in one direction.

During the operation of the butterfly valve, a large force is transmitted to the gear drive of the worm gear (2) and the worm wheel (10), and also, due to the nature of the worm and the worm gear (2), a large friction force is involved, so the worm gear (2) is regularly replaced. Alternatively, replacement work for maintenance of the worm wheel 10 is an essential work.

For example, in order to replace the worm wheel 10, as shown in FIG. 1, the worm wheel 10 can be removed from the rotation axis 11 of the worm wheel 10 using the bearing pulley 20.

In this regard, to briefly explain the removal sequence, first, place one side of the center bar 21 of the bearing pulley 20 at the center of the rotation axis 11 of the worm wheel 10, and then place the center bar 21 on both sides around the center bar 21. The legs 24 arranged to be capable of cutting are mounted on both sides of the worm wheel 10 to rotate the hexagonal tip A provided at the end of the center rod 21 to rotate the rotation axis 11 relative to the worm wheel 10. When pushed out, the worm wheel 10 can be separated from the rotation shaft 11.

At this time, the bearing pulley 20 may be further provided with a support frame 22 and a connecting bar 23 between the center rod 21 and the leg 24.

The support frame 22 is arranged to enable straight reciprocating movement along the longitudinal direction of the center bar 22 by rotation of the center bar 22.

Additionally, the connecting bar 23 is arranged to connect the center bar 21 and the support frame 22 in a diagonal direction.

At this time, the worm wheel 10 may be provided in various sizes depending on the size of the valve, and accordingly, the rotation axis 11 of the worm wheel 10 may also be provided in various sizes.

In response to this, the bearing pulley 20 may need different sizes depending on the size of the legs 24 or support frame 22 so that it can correspond to the size of the worm wheel 10.

However, there is a limit to providing the bearing pulley 20 in a plurality of sizes to correspond to the size of the worm wheel 10, and the internal space of the housing 10 for separating the worm wheel 10 is narrow, so the bearing pulley Since there is a limit to increasing the size of (20), problems related to this are continuously being raised.

In addition, due to the small internal space of the housing 10, disassembly work cannot proceed smoothly, and as a result, problems of safety accidents occurring due to unreasonable work progress are being raised.

Figure 2 is a perspective view showing a gear disassembly device according to an embodiment of the present invention.

Referring to Figure 2, the gear disassembly device 100 according to an embodiment of the present invention includes a support plate 111, a steel wire bolt 121, a wire 123, a guide portion 112, and a cylinder 30. It can be included.

First, the support plate 111 may be made of a substantially rectangular metal material and may be made of a thin plate shape. Of course, the shape of the support plate is not limited to this. The thickness of the support plate may range from approximately 4 to 10 mm, and more preferably approximately 6 mm.

In addition, one end of the steel wire bolt 121 may be coupled to the support plate 111, and a wire 123 may be coupled to the other end. The steel wire bolt 121 has a substantially round bar shape formed long along the longitudinal direction, and a thread may be formed on the outer peripheral surface.

Here, a pair of through holes 115 into which the steel wire bolts 121 can be coupled are formed in the support plate 111, and the inner peripheral surface of the through holes 115 can engage with the male screw formed at one end of the steel wire bolt 121. A female thread may be formed so that That is, the fastening depth of the steel wire bolt 121 on the support plate 111 can be adjusted along the longitudinal direction.

Of course, a female thread is not formed on the inner peripheral surface of the through hole 115 of the support plate 111, and a separate bolt 124 may be fastened to the portion where one end of the steel wire bolt 121 penetrates the through hole 115 of the support plate. . Accordingly, the fastening depth at which the steel wire bolt 121 is coupled to the support plate 111 may be adjusted depending on the position at which the bolt 124 is fastened at one end of the steel wire bolt 121. In this embodiment, the bolt 124 fastened to one end of the steel wire bolt 121 will be described as an example. Of course, at one end of the steel wire bolt 121, two bolts 124 may be coupled in a tightened direction adjacent to each other to prevent the bolt 124 from loosening.

A connecting ring 122 may be provided at the other end of the steel wire bolt 121.

The connecting ring 122 is an area where both ends of the wire 123 are joined, and the combined length of the wire 123 on the connecting ring 122 can be easily adjusted.

Of course, the connecting ring 122 may be formed integrally with the other end of the steel wire bolt 121. Alternatively, the connecting ring 122 may be provided to be selectively detachable from the other end of the steel wire bolt 121.

Additionally, both ends of the wire 123 may be coupled to each connection ring 122 on both sides. The wire 123 may have a diameter ranging from approximately 6 to 15 mm.

More preferably, it may be made of about 9mm steel wire. The wire 123 may be formed to have a length of approximately 2 m from one end to the other end, and the diameter or length of the wire 123 is not limited thereto.

Of course, the wire 123 may be fixed on the connecting ring 122 through a wire clip or wire socket, and the length of the wire 123 coupled to the connecting ring 122 may be adjusted separately.

Although not shown in the drawing, the wire 123 may be fixed on the support plate 111 without the steel wire bolt 121. In addition, the wire 123 can be configured to adjust the length of the wire 123 by combining a turnbuckle (not shown) between the support plate 111 and the wire 123 or between the steel wire bolt 121 and the wire 123. You can.

Additionally, one side of the guide portion 112 is fixed to the center area of the support plate 111. The guide portion 112 may be fixed to the support plate 111 through welding or may be integrally formed. The guide portion 112 may have an opening 113 through which a cylinder (see FIG. 3, 30) can be inserted on the other side.

The guide portion 112 has a hollow cylindrical pipe structure, and a slit 114 may be formed along the longitudinal direction.

That is, one cross-section of the guide portion 112 in the circumferential direction may be approximately “C” shaped. In this embodiment, the slit 114 is formed along the longitudinal direction of the guide portion 112 to cut the entire guide portion 112, but one end of the guide portion 112 is coupled or fixed to the support plate 111. It may also be implemented in a partially uncut shape.

The guide portion 112 may be formed to elastically open in the circumferential direction along the slit 114. For example, one side of the cylinder 30 may be partially inserted into the guide portion 112. In this case, one side of the cylinder 30 is inserted inside the other end of the guide portion 112, or the guide portion 112 It may be inserted so that one outer peripheral surface of the cylinder 30 is elastically pressed inside the other end of the cylinder 30.

Alternatively, it is possible to check whether the tip of the cylinder 30 whose length is variable touches the inner surface of the support plate 110 through the slit 114 of the guide portion 112.

Additionally, the cylinder 30 may be a cylindrical jack capable of providing pressure through pneumatic or hydraulic pressure.

In this embodiment, for example, a hydraulic jack can be used as the cylinder 30, and in addition to hydraulic pressure, pneumatic or electric actuators can also be applied.

The cylinder 30 may be arranged so that one end, the upper part, is partially inserted into the guide part 112, and the other end, the lower part, is supported on the rotation axis 11 of the worm wheel 10.

"110", which is not explained in Figure 2, can be applied as a fixing and support means 110 including the support plate 111 and the guide part 112, and "120" refers to the steel wire bolt 121 and the connecting ring 122. And it can be applied as an adjustment means 120, including the wire 123. That is, the fixing and supporting means 110 can fix and support the cylinder 30 on the rotating shaft 11, and the adjusting means 120 adjusts the gap between the steel wire bolt 121 and the support plate 111 or , the length of the wire 123 surrounding the worm wheel 10 can be adjusted.

Figure 3 is a perspective view showing a state in which the gear disassembly device shown in Figure 2 is mounted on a gear.

Referring to Figure 3, the operating method of the gear disassembly device according to an embodiment of the present invention will be described in detail.

The gear disassembly device 100 connects the wire 123 to wrap around the worm wheel 10 so that it is adjacent to the rotation axis 11 of the worm wheel 10. Of course, the process of connecting the wire 123 is not to separate the wire 123 from the connecting ring 122, but to place the wire 123 around the worm wheel 10 and then tighten or loosen the bolt 124 to connect the support plate ( When adjusted to maintain an appropriate distance from 111), the wire 123 connection process is completed.

When the wire 123 is connected to the worm wheel 10, the cylinder 30 is positioned inside the guide portion 112 to maintain close contact between the cylinder 30 and the support plate 111.

At this time, the adhesion process between the cylinder 30 and the support plate 111 can be carried out more flexibly by adjusting the coupling depth at which the steel wire bolt 121 is fastened to the support plate 111.

When the cylinder 30 is placed in close contact between the support plate 111 and the rotation shaft 11, pressure is provided to the cylinder 30 to press the support plate 111 in a direction away from the rotation shaft 11.

At this time, when the support plate 111 moves away from the rotation axis 11, the wire 123 surrounds the worm wheel 10, so the worm wheel 10 is gradually pushed outward from the rotation axis 11.

Of course, although not shown in the drawings, a support piece (not shown) formed at least equal to or smaller than the diameter of the rotation shaft 11 may be further provided on the other side of the cylinder 30. For example, if the other side of the cylinder 30 is larger than the diameter of the rotation axis 11 of the worm wheel 10, the worm wheel 10 interferes with the other side of the cylinder 30 during the separation process, making it difficult to discharge any more. Therefore, a support piece having a smaller diameter than the diameter of the rotating shaft 11 may be placed on the rotating shaft 11 to prevent the other side of the cylinder from directly contacting the worm wheel 10.

Therefore, according to the gear disassembly device according to the embodiment of the present invention, it can be applied to disassemble worm wheels of various sizes in response to the non-constant size of the worm wheel, and compared to the bearing pulley for disassembling the existing worm wheel, disassembly is easier. A wider work space can be secured inside the gear box where work is performed, and worker safety can be secured as securing work space and responding to the worm wheel size become easier, and work time is shortened due to simple preparatory work. Because it saves money, it has the effect of improving work efficiency.

In the above, specific embodiments have been shown and described to illustrate the technical idea of the present invention, but the present invention is not limited to the same configuration and operation as the specific embodiments as described above, and various modifications may be made without departing from the scope of the present invention. It can be implemented within limits. Accordingly, such modifications should be considered to fall within the scope of the present invention, and the scope of the present invention should be determined by the claims described below.
