Embodiments of the present disclosure provide a rail grinding wheel sander for sanding primarily a rail to eliminate or at least reduce damage on the rail. In particular, viewed in its entirety (fig. 1), the rail grinding wheel sander of the present disclosure extends in a direction (lateral or horizontal) perpendicular to the direction in which the rails extend, for example, as described in detail below, the chassis 2 extends in the lateral direction to ride on two rails, within the extension of which is disposed a grinding wheel sanding device or the like. The steel rail grinding wheel polisher can polish one of two parallel steel rails on a railway.
As shown in fig. 1 to 5, the rail grinding wheel sander of the present disclosure includes: a chassis; a power supply device; and a grinding wheel polishing device, wherein the chassis is used for bearing, connecting, supporting or installing the power supply device and the grinding wheel polishing device. The rail grinding wheel polisher further comprises a lifting pressing device. The rail grinding wheel sander of the present disclosure further comprises an angle deflection device. The rail grinding wheel sander of the present disclosure further comprises a horizontal traversing device. Wherein the angle deflection means, the lifting pressure means and the horizontal traverse means are also carried, connected, supported or mounted by the chassis and are preferably arranged in the space enclosed by the chassis. In the case of a horizontal traverse device, a grinding wheel dressing device, an angle deflecting device and a lifting and pressing device are connected to the horizontal traverse device, and further to the base frame. Therefore, the rail grinding wheel polisher can deflect and transversely move around a rail and feed in the vertical direction (up and down), achieves polishing of +60 degrees to-30 degrees of damages such as welding seam joints, traveling faces and welding beading at welding seams of the rail, corrects the profile of a rail head, and meets polishing maintenance requirements.
Hereinafter, each of the above-described devices, mechanisms, elements, components, and the like will be described in detail.
< Chassis >
The chassis (or frame, walking frame) 2 is used to directly or indirectly arrange, support, connect, mount or carry various devices, mechanisms, elements, components, etc. of the rail grinding wheel sander and guide the rail grinding wheel sander to travel along the rail. For example, in the illustrated embodiment, the wheel sharpening unit may be indirectly connected to the base frame by a lift and lower pressure application device, and by a horizontal traversing device. Of course, it will be understood by those skilled in the art that the connection of the wheel sanding device, the lifting and pressing device, the angular deflection device, and the horizontal traversing device to the undercarriage may be combined in any combination, and is not intended to be limiting. That is, at least one or all of the wheel grinding device, the lifting and pressing device, the angle deflecting device, and the horizontal traversing device may be directly connected to the base frame, or may be indirectly connected to the base frame through any one of them.
As best shown in fig. 2, the chassis 2 is configured in a generally rectangular shape. For example, four beams constitute the substantially rectangular shape. Further, to facilitate miniaturization of the rail grinding wheel sander, the length of the beam extending parallel to the rail direction (longitudinal direction) is smaller than the length of the beam extending perpendicular to the rail direction (lateral or horizontal direction). Therefore, hereinafter, the laterally extending beams are referred to as "primary beams", and the longitudinally extending beams are referred to as "secondary beams". The main beam comprises an expansion link to adjust the length of the main beam, so that the steel rail grinding wheel polisher disclosed by the invention can adapt to steel rails embedded according to different spacing specifications.
As shown in fig. 1, most of the devices, elements, and the like constituting the rail grinding wheel dresser of the present disclosure are defined in a space surrounded by the base frame 2.
To facilitate operation of the rail grinding wheel sander, a push rod armrest 22 is provided on the chassis 2. The push bar handle 22 may be a member detachably attached to the base frame 2, for example, by riveting, fastening, or the like, or may be a member extending from a main beam of the base frame 2 and integrated with the base frame 2. In one embodiment, the pusher handrail 22 extends upward from 2 main beams and meets at a top end to assume a generally inverted U-shape. When the rail grinding wheel sander is in operation, a worker can place his or her hands on the push-stick armrest 22 to operate the rail grinding wheel sander for forward and backward movement. Where a horizontal traversing device is provided, the pusher handrail 22 may be attached (e.g., removably mounted by riveting, fastening, etc.) to the horizontal traversing device, rather than to the main beam.
In addition to the push bar handle 22, at least one of the two sides (perpendicular to the direction in which the rails extend) of the chassis 2 may be provided with a handle 16 for grasping by a worker to assist in the handling of the rail grinding wheel sander. Fig. 1 shows four handles 16.
In order to facilitate the running of the rail grinding wheel sander along the rail, a moving device, such as a guide wheel 1, is mounted below the base frame 2. The guide wheel 1 may be connected to the base frame 2 by riveting, welding, etc., preferably to a guide wheel post 2a extending from the base frame 2 in the direction of the rail.
The number of guide wheels 1 is not limited, and four guide wheels 1 are preferably provided so that 2 guide wheels contact one steel rail.
To ensure that the runner 1 can travel on the rail without coming off the rail, a stopper 1a is provided on the runner 1. Fig. 2 shows an embodiment of the stop 1 a. The stop 1a is configured as a circular disc having a diameter larger than that of the guide wheel 1 and is coaxially mounted on the side surface of the guide wheel. The diameter of the stop 1a ensures that a portion of the stop 1a covers a portion of the rail after it is mounted on the guide wheel 1. A stopper 1a may be provided at one side of the guide wheel 1 (as shown). Alternatively, the stoppers 1a may be provided on both sides of the guide pulley 1. When the stop 1a is provided on only one side of the guide wheel 1, the stop 1a is mounted so that the stops 1a on different guide wheels cooperate with each other to prevent a wide range of movement of the sander in the transverse direction. For example, the guide wheels may be mounted as follows: the sides of the guide wheels having the stoppers 1a are all located inside the rail or all located outside the rail.
Preferably, an insulating member (not shown) is provided between the guide wheel 1 and the base frame 2 to prevent static electricity or the like caused by friction between the guide wheel 1 and the rail from interfering with other devices or components of the rail grinding wheel sander.
Preferably, a stiffening beam 27 is provided between the main beams. The reinforcement beam 27 can, on the one hand, increase the strength of the chassis 2 and, on the other hand, also provide support for the screw 3 (described later).
< Power supply device >
The power supply device is used for supplying power to one or more of various devices, mechanisms, elements and parts in the rail grinding wheel sander. Preferably, the power supply device supplies power only to a motor 9 (described later) in the wheel grinding device.
The power supply device is supported by the chassis 2. The power supply means may be mounted directly on the chassis 2. Alternatively, the power supply device is mounted to the base frame 2 by a support fixed to the base frame 2. The support may be, for example, a support plate 21 as shown in fig. 2. The support plate 21 is fixed between the main beams of the base frame 2 by means of, for example, welding.
The power supply device is preferably located on the side of the base frame 2 opposite to a grinding wheel dressing device described later, for example, as shown in fig. 1. The power supply device is located on the left side (first side) of the base frame 2, and the wheel sharpening device is located on the right side (second side) of the base frame 2. This is advantageous in maintaining the balance of the wheel sander itself.
As shown in fig. 1, the power supply device includes a battery box 14 and an electric box 15 that are separately arranged. Alternatively, the power supply device is in an integrated mode, i.e., the battery box 14 and the electrical box 15 are integrated in one housing.
The installation of the battery box 14 and the electrical box 15 is not limiting. In the case of including a separately arranged battery box 14 and electrical box 15, the battery box 14 may be mounted on a battery box platform while the electrical box 15 is mounted on an electrical box platform. The battery box platform and the electric box platform are respectively fixed with the underframe 2. Alternatively, both are mounted on the support plate 21.
The power supply means may take the form of a removably rechargeable battery, or other form. The rechargeable battery is removably arranged in the battery box 14. Alternatively, the battery box 14 may be eliminated and the batteries may be placed directly on the chassis or on the battery box platform.
An electrical matching system is arranged in the electrical box 15, and modules for motor operation control, safety protection, light and the like are arranged in the electrical box. Preferably, the electrical box is further provided with a display to display the remaining capacity of the battery.
< grinding wheel dressing apparatus >
The details of the grinding wheel dressing apparatus are described below with reference to the drawings.
The grinding wheel grinding device may be supported by the base frame 2. Alternatively, the grinding wheel sharpening unit may be mounted to the base frame 2 by, for example, a bracket attached to the base frame 2. The grinding wheel polishing device is mounted on the other side of the chassis 2 different from the side on which the power supply device is mounted. With the lifting press described later, the wheel sharpening unit is mounted to the lifting press, both on the second side of the base frame.
As best shown in fig. 5, the grinding wheel dressing device includes a motor 9, a grinding wheel connecting sleeve (or grinding wheel connecting rod) 20, and a grinding wheel 5. The motor 9, the grinding wheel connecting sleeve 20 and the grinding wheel 5 are coaxially arranged. The output shaft of the motor 9 is connected to the grinding wheel 5 through the grinding wheel connecting sleeve 20, so that the grinding wheel 5 is driven to rotate, and the grinding of the steel rail by the grinding wheel is realized. The motor 9 is powered by a power supply.
Further, the grinding wheel dressing apparatus further includes a wheel guard 39 and a wheel guard (not shown).
In the case where a lifting and lowering pressing device described later is provided, the grinding wheel dressing apparatus further includes a support base 25 for connection with the lifting and lowering pressing device. In this case, the grinding wheel dressing device may be connected to the lifting and pressing device instead of to the base frame 2.
< lifting/lowering pressing device >
In order to realize that the steel rail grinding wheel polisher can move up and down along the height direction, a lifting pressure device is arranged on the bottom frame 2. In the case of having an angle deflecting device described later, the elevation pressing device is attached to at least one of the angle deflecting device and the base frame. The lifting pressure device is connected with the grinding wheel polishing device to control the height of the grinding wheel polishing device.
The construction of the lifting press is best seen in figures 4 and 5. The lifting pressure applying device comprises a linear guide rail 4, a (multi-stage) lifting slide block 18, a lifting screw rod 26 and a lifting hand wheel 10. One end of the lifting screw 26 is connected with the lifting hand wheel 10, the other end of the lifting screw is connected with the multi-stage lifting slider 18 through a screw nut, and the multi-stage lifting slider 18 moves up and down along the lifting screw 26 by rotating the lifting hand wheel 10. The multistage lifting slide block 18 is fixedly connected with a supporting seat 25 of the grinding wheel polishing device, and the lifting hand wheel 10 is rotated to drive a lifting screw 26 to rotate, so that the multistage lifting slide block 18 is driven to move up and down along the linear guide rail 4, and further the grinding wheel polishing device is driven to move up and down.
The lifting and pressing device is also provided with a scale pointer 28 to visually display the height of the grinding wheel grinding device.
The lifting pressure-applying device also comprises a deflection shaft device 40 which comprises a deflection shaft and a deflection shaft seat, wherein the deflection shaft seat is arranged below the linear guide rail 4, the deflection shaft is fixedly arranged on the underframe 2 (or a transverse moving frame 7 which is described later), when the deflection shaft swings, the deflection shaft is not moved, and the deflection shaft seat drives the lifting pressure-applying device and the grinding device to integrally deflect around the deflection shaft. For example, the diameter of the deflection axis is at least 30mm, such as 35mm, 40mm, 45mm, 50mm, etc., preferably 45 mm. The material of the deflection shaft is metal, alloy, etc., preferably 45 steel.
Therefore, the lifting pressure device adopts the linear module and the screw rod sliding block, and has good guidance performance and stability.
In the case where an angle deflecting device described later is provided, the elevation pressing device further includes a member for connecting with the angle deflecting device. In this case, the grinding wheel dressing device may be connected to a lifting pressure device, which is connected to an angle deflection device, which is connected to the base frame 2.
< Angle deflecting device >
In order to realize that the angle of the grinding wheel polishing device relative to the steel rail can be adjusted, an angle deflection device is arranged. In the case of a horizontal traverse device described later, the angle deflecting device is provided in connection with at least one of the traverse frame and the base frame of the horizontal traverse device. The angle deflection device is connected directly or indirectly to the grinding wheel grinding device to control the height of the latter. For example, the angle deflection device is connected with a lifting and pressing device which is connected with a grinding wheel grinding device
The angle deflection device comprises a swinging hand wheel 11, a hand wheel shaft 29, a deflection pinion 17, a rack 8 and the like, wherein the rack 8 is installed on a rack fixing plate (not shown), the rack fixing plate is connected with the linear guide rail through a bolt and the like, and a corresponding circular lightening hole is formed in the rack fixing plate. The angle deflection device is connected with the lifting pressure device, and the lifting pressure device is connected with the grinding wheel polishing device. Thus, the operator can change the angle of the grinding wheel sharpening device (in particular the grinding wheel 5) with respect to the rail by operating the oscillating hand wheel 11. The oscillating hand wheel 11 is connected to a deflection pinion 17 via a hand wheel shaft 29, the deflection pinion 17 being in engagement with a toothed sector on the linear guide 4. When the swinging hand wheel 11 is rotated, the angle deflection device and the grinding wheel grinding device are deflected integrally (leftwards or rightwards).
The angular deflection device also comprises a detent 19 to enable locking of the angular deflection device in any position. The positioner 19 is provided with a brake block which can be directly inserted into the rack gap of the rack 8 to realize locking and positioning.
In order to visually reflect the angle of the grinding wheel grinding device (in particular the grinding wheel 5) relative to the rail, a scale 23 is provided on the angle deflection device, on which scale 23 the angle of deflection can be displayed. The scale 23 is attached to the rack fixing plate by means of, for example, rivets.
In the case where a horizontal traverse device described later is provided, the angle deflecting device further includes a member for connecting with the horizontal traverse device (for example, "52", and in the case where the horizontal traverse device is not provided, the member may be, for example, a member for connecting the angle deflecting device to the base frame 2). As shown, one of the members 52 is, for example, a trapezoidal shaped bracket sized and constructed to securely support an angular deflection device or the like. For example, the trapezoidal bracket is formed by connecting square pipes with the thickness of at least 15mm, the wall thickness of the trapezoidal bracket is at least 1.5mm, and the trapezoidal bracket is made of metal. Preferably, the trapezoid support is formed by connecting square pipes with the sizes of 20mm, 26mm, 28mm, 30mm, 33mm, 37mm and the like. The wall thickness is selected from 2.0mm, 2.3mm, 2.5mm, 2.8mm, 3.0mm, 3.4mm, 3.5mm, etc. Examples of the material include steel and aluminum alloy. In the embodiment, the trapezoid support is a 30mm square tube with the wall thickness of 2.5mm and is made of Q235-B. The other of the members 52 is a plate-like member of a size, material and thickness to securely support the traverse device and the like. In this case, the grinding wheel dressing device may be connected to a lifting pressure application device connected to an angle deflection device connected to a horizontal traverse device connected to the base frame 2.
< horizontal traverse device >
To enable the grinding wheel sander to be movable in a direction perpendicular to the rails (lateral, left-right), a horizontal traverse device is provided on the chassis 2. Specifically, the traverse frame 7 of the horizontal traverse device is provided to be slidably connected to the base frame 2. The horizontal traversing device is directly or indirectly connected with the grinding wheel polishing device.
As best shown in fig. 3, the horizontal traverse device includes a traverse frame 7, a lead screw 3, a worm gear mechanism 13, and a traverse hand wheel 12. Preferably, the horizontal traversing device further comprises wheels 6.
The traverse frame 7 is configured in a substantially rectangular shape, for example, composed of 4 beams, and has substantially the same size in the longitudinal direction as the base frame 2. Further, the wheels 6 include 4 wheels installed at 4 corners of the traverse frame 7, or 3 wheels may be provided to constitute a substantially triangular shape. The wheels 6 are preferably U-shaped wheels. The rolling contact portions (central recessed portions) of these U-shaped wheels 6 are in contact with the main beams of the chassis 2 to guide the traverse frame 7 to move along the main beams.
In the case of a horizontal traverse device, the aforementioned grinding wheel dressing device, angle deflecting device, and lifting and pressing device are directly or indirectly connected to the traverse frame 7, not to the base frame 2, so that these devices as a whole can be synchronously moved horizontally.
