For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] As Figure 1 and Figure 2 shown, the present utility model provides a brake caliper disassembly and assembly device, including a base 1, a vertical beam 2, a boom 3, and a hanging assembly 4.

[0041] Among them, a moving wheel 14 is installed at the bottom of the base 1, and an operator can push the device to move on the ground, facilitating the movement of the device into or out of the installation position of the brake caliper. The vertical beam 2 is vertically installed on the base 1 and is configured to be height-adjustable and rotatable in the horizontal direction, for adjusting the height of the boom 3 and the rotation angle of the boom 3 according to the on-site environment. The boom 3 extends horizontally, and one end is rotatably installed at the top of the vertical beam 2. When hoisting, the boom 3 is extended between the brake caliper and the vehicle body (not shown in the figure). The hanging assembly 4 is installed on the boom 3 and is used to connect the brake caliper during hoisting.

[0042] For a bogie that has been lowered onto the track, when it is necessary to disassemble the brake caliper, move the device to the installation position of the brake caliper, extend the lifting arm 3 between the car body and the bogie, and then the operator connects the hanging assembly 4 to the brake caliper, so that the brake caliper can be lifted and then removed from the bogie along with the device. The same operation is adopted during installation. In this way, using this device, the disassembly and assembly operations of the brake caliper can be completed in the case of a lowered bogie, meeting the requirements for the disassembly and assembly of the brake caliper without the need to lift and lower the bogie, saving a large amount of materials, manpower, etc. consumed during each lifting and lowering of the bogie, greatly reducing the disassembly and assembly operation time of the brake caliper, and improving the disassembly and assembly efficiency of the brake caliper.

[0043] In this embodiment, the hanging assembly 4 further includes a hook, a lifting rope (not shown in the figure), a two-way winch 41 and a fixed pulley 42. One end of the lifting rope 42 is connected to the hook, and the other end is connected to the two-way winch 41. The two-way winch 41 is installed on the vertical beam 2. Fixed pulleys 42 are respectively installed at both ends of the lifting arm 3, and the fixed pulleys 42 installed at both ends of the lifting arm 3 are installed at the ends of the lifting arm 3. Of course, the fixed pulley 42 can also be installed above the lifting arm 3. The lifting rope 42 successively passes around the two fixed pulleys 42 and is connected to the hook and the two-way winch 41. According to the installation situation of the brake caliper on site, the operator can operate the two-way winch 41 to take in and release the lifting rope 42, so that the hook is firmly connected to the brake caliper, meeting the requirements for lifting and lowering the brake caliper and ensuring that it will not fall during the hoisting process.

[0044] In this embodiment, further, a flat sling (not shown in the figure) is installed on the hook. The sling passes through the lifting point of the brake caliper and is hung on the hook to complete the hoisting of the brake caliper.

[0045] In this embodiment, the vertical beam 2 includes a base body 21 and a telescopic rod 22. The bottom of the base body 21 is fixed on the base 1, the bottom of the telescopic rod 22 is nested in the base body 21, and the telescopic rod 22 is connected to the driving device 23. By using the driving device 23 to drive the telescopic rod 22 to move up and down relative to the base body 21, the height can be adjusted, and the entire lifting arm 3 can be adjusted upward by 1 - 20 cm.

[0046] In this embodiment, the driving device 23 preferably adopts a jack 231, and the bottom of the jack 231 is fixed on the base 1. The shape of the base body 21 preferably adopts a cylindrical tube shape, and the bottom can be directly welded to the base 1 or fixed to the base 1 by bolts. In order to facilitate the maintenance of the driving device 23, in this embodiment, it is further preferably to open a maintenance opening 211 on the base body 21 to expose the driving device 23 outside.

[0047] Furthermore, in order to improve the structural strength between the vertical beam 2 and the base 1 and facilitate the enhancement of the stability of the vertical beam 2, a plurality of reinforcing plates 8 are circumferentially arranged at the bottom of the base body 21. The reinforcing plates 8 preferably adopt a triangular structure, and the two right-angled sides of the reinforcing plates 8 are respectively welded to the base body 21 and the base 1.

[0048] In this embodiment, one end of the lifting arm 3 is rotatably installed at the top of the telescopic rod 22. While the telescopic rod 22 moves up and down, it can also rotate 360° in the horizontal direction relative to the base body 21, thereby driving the lifting arm 3 to rotate 360° in the horizontal direction. Specifically, a fixed seat 24 is installed at the top of the telescopic rod 22, and the lifting arm 3 is fixedly connected to the fixed seat 24 in a hinged manner. In this way, the lifting arm 3 can rotate 360° in the horizontal direction and can also rotate up and down in the vertical direction to adjust the levelness of the lifting arm 3 relative to the ground.

[0049] In this embodiment, in order to enable the telescopic rod 22 to lift and rotate stably, it is further preferred that a rotating seat 25 is installed in the base body 21. The rotating seat 25 includes a chassis 251 and a guide cylinder 252 installed above the chassis 251. The chassis 251 can move up and down in the base body 21, and the chassis 251 is fixedly connected to the top of the output end of the jack 231. Under the action of the jack 231, the chassis 251 moves up and down along the base body 21. The bottom of the telescopic rod 22 is embedded in the guide cylinder 252 and rotates in the guide cylinder 252. The central axes of the guide cylinder 252, the telescopic rod 22, and the base body 21 coincide, and the guide cylinder 252 plays a role in stably supporting the telescopic rod 22. Further, a first bearing 26 is installed between the bottom of the telescopic rod 22 and the guide cylinder 252, which can ensure that the telescopic rod 22 moves up and down and rotates 360° relative to the base body 21 smoothly.

[0050] In this embodiment, in order to make the overall structure of the vertical beam 2 stable, the telescopic rod 22 is composed of upper and lower parts. The diameter of the upper part is larger than that of the lower part. The upper part can be a cylindrical structure identical to the base body 21. The lower part is welded to the upper part, and the top of the lower part can further be inserted into the upper part and welded to the inner wall of the upper part. The lower part is embedded in the base body 21, and the bottom of the lower part is embedded in the guide cylinder 252 and rotates in the guide cylinder 252. The diameter of the upper part is equivalent to or slightly smaller than the diameter of the base body 21.

[0051] A locking mechanism 5 is further installed between the base body 21 and the telescopic rod 22, which is used to lock the relative rotation angle between the telescopic rod 22 and the base body 21, that is, to lock the rotation angle of the lifting arm 3, ensuring that the lifting arm 3 will not rotate again during the hoisting process, for the hoisting efficiency and hoisting quality.

[0052] The locking mechanism 5 can adopt any structure in the prior art that can fixedly connect two components together. In this embodiment, preferably, the locking mechanism 5 includes a clamp 51 and a sleeve 52. The clamp 51 and the sleeve 52 are an integral structure. The clamp 51 is arranged above the sleeve 52. The clamp 51 extends out of the base body 21 and has a diameter larger than that of the sleeve 52. An opening slit 53 is provided between the clamp 51 and the sleeve 52 to provide a certain deformation amount for the clamp 51 and improve the clamping effect. The sleeve 52 is embedded and fixed in the base body 21. The upper half of the telescopic rod 22 is embedded in the clamp 51, and the lower half of the telescopic rod 22 is embedded in the sleeve 52. The telescopic rod 22 rotates within the clamp 51 and the sleeve 52. A fastening bolt (not marked in the figure) is installed on the clamp 51. By tightening the fastening bolt, the telescopic rod 22 is locked.

[0053] In this embodiment, furthermore, the bottom of the sleeve 52 is fixed on the chassis 251 to ensure that the relative angular relationship between the sleeve 52 and the base body 21 remains unchanged and can move together with the telescopic rod 22. Even further, a second bearing 27 is also installed between the top of the lower half of the telescopic rod 22 and the sleeve 52 to further improve the smoothness of the telescopic rod 22 during rotation.

[0054] In this embodiment, preferably, it further includes a locking assembly 6. The locking assembly 6 is used to lock the telescopic rod 22 to prevent the telescopic rod 22 from moving up and down during operation, so that the boom 3 always remains at the adjusted height, thereby ensuring operation safety. The locking assembly 6 preferably adopts a structure of a jacking screw, including a handle and a jacking screw (not marked in the figure). One end of the jacking screw is connected to the handle, and the jacking screw is threadedly connected to the base wall of the base body 21. The other end of the jacking screw abuts against the outer wall of the telescopic rod 22 to assist in fixing the telescopic rod 22 at the adjusted height position.

[0055] Since the height space available for the boom 3 to extend between the bogie and the car body is limited, in this embodiment, an angle adjustment mechanism 7 is also installed between the boom 3 and the vertical beam 2 to adjust the levelness of the boom 3 to facilitate the boom 3 to be inserted into the space between the bogie and the car body on site.

[0056] In this embodiment, the angle adjustment mechanism 7 preferably adopts an oil cylinder 71. The fixed end of the oil cylinder 71 is rotatably connected to the upper half of the telescopic rod 22 of the vertical beam 2, and the telescopic end is rotatably connected to the boom 3. Specifically, it can be rotatably connected by means of a hinge. The operator adjusts the levelness of the boom 3 through the telescopic movement of the oil cylinder 71 according to the on-site environment, so that the boom 3 can be smoothly inserted into the operation space. According to the operation space for disassembling and assembling the brake caliper, in this embodiment, more preferably, the length of the boom 3 is between 1.1 - 1.3 m.

[0057] As Figure 1As shown, in this embodiment, the base 1 is composed of two side beams 11, two connecting beams 12 and a support plate 13. The side beams 11 and the connecting beams 12 can be made of metal round tubes or metal square tubes. The two side beams 11 form an angle, and the overall shape is V-shaped. To ensure the stability of the base 1, the distance between the widest openings of the two side beams 11 is more than 1 m, and the length of the side beam 11 is greater than the length of the lifting arm 3, which is conducive to expanding the support area of the base 1 on the ground. The two connecting beams 12 are installed at one end of the narrow end between the two side beams 11. The connecting beam 12 can be welded to the side beam 11 or fixed to the side beam 11 by bolts. The support plate 13 is welded to the connecting beam 12 and the side beam 11, and the bottom end of the vertical beam 2 is fixed to the support plate 13. The vertical beam 2 and the support plate 13 can be welded together or fixed by bolts. The extending direction of the lifting arm 3 is the same as the extending direction of the side beam 11 relative to the support plate 13, making the whole device in an arch shape with a reasonable center of gravity. The base 1 not only has a simple overall structure, but also has a reasonable center of gravity for the whole device, making the structure of the device stable and not prone to tipping and overturning during the hoisting of the braking clamp, and it is safe and reliable to use.

[0058] In this embodiment, further preferably, a plurality of support beams (not shown in the figure) extending in different directions are also installed on the base 1. A total of three support beams are provided in the figure, which are respectively arranged outside the two side beams 11 and outside the connecting beam 12. A support footing (not shown in the figure) is installed under each support beam. After the support beam is installed, it can support on the ground and can effectively expand the support area of the base 1 on the ground, further preventing the device from tipping over during the hoisting process if the rotation angle of the lifting arm 3 is relatively large, and further improving the safety of use of the device.

[0059] In this embodiment, even more preferably, the support beam is detachably and fixedly connected to the base 1, which can simplify the overall structure of the base 1 and also facilitate the disassembly and assembly of the support beam. When it is necessary to move, the support beam can be removed. When it is necessary to disassemble and assemble the braking clamp after moving in place, the support beam is installed on the base 1 again.

[0060] Specifically, sockets (not shown in the figure) corresponding to the number and installation direction of the support beams are provided on the base 1. Slots are provided on the sockets. One end of the support beam is inserted into the corresponding slot to complete the connection between the support beam and the base 1. The cross-section of the slot is the same as that of the support beam, and it can be a circular shape, a square shape or a U-shaped groove, etc. The sockets can be welded to the side beam 11, the connecting beam 12 and the support plate 13 of the base 1 as required.

[0061] Such as Figure 1 and Figure 2As shown in the figure, in this embodiment, in order to facilitate the operator to push the device, a handle assembly 9 for pulling the device is installed on the vertical beam 2. The handle assembly 9 includes a mounting base 91 which is fixed on the vertical beam 2. The mounting base 91 preferably adopts a U-shaped structure composed of two side plates and a bottom plate. A connecting rod 92 is installed on the mounting base 91. The connecting rod 92 is installed between the two side plates of the mounting base 91 and is rotatably connected to the two side plates, so that the connecting rod 92 can rotate relative to the mounting base 91 in the vertical direction. A handle 93 perpendicular to the connecting rod 92 is installed at the other end of the connecting rod 92. The handle 93 can be selected as a square tube or a round tube. Under the action of the connecting rod 92, the handle 93 can be lifted to any height, which is convenient for operators of different heights to push the device to move on the ground.

[0062] The brake caliper disassembly and assembly device provided by the present utility model has the following advantages:

[0063] 1. Using this device, the disassembly and assembly operation of the brake caliper can be completed when the vehicle is lowered, meeting the requirement of disassembling and assembling the brake caliper without lifting and lowering the vehicle, saving a large amount of materials, manpower, etc. consumed during each lifting and lowering of the vehicle, greatly reducing the disassembly and assembly operation time of the brake caliper, and improving the disassembly and assembly efficiency of the brake caliper.

[0064] 2. The overall structure of this device is simple, and it is flexible and convenient to use. The vertical beam can not only be adjusted in height, but also can rotate 360° in the horizontal direction. The operator can arbitrarily adjust the working height and angle of the boom according to the on-site needs, which can prevent the boom from interfering with the bogie, and further improve the use efficiency of this device.

[0065] 3. Through the setting of the locking mechanism and the locking component, this device can ensure that the working height and working angle of the boom are locked during the hoisting process, and there will be no up and down movement and rotation during the hoisting process, ensuring the safety and reliability of the operation.

[0066] 4. The overall structure is simple, and the center of gravity of the whole device is reasonable, making the structure of the device stable, and it is not easy to tip over and capsize when hoisting the brake caliper, and it is safe and reliable to use.
