[0030] As Figure 1 and Figure 2 shown, the present utility model provides a disassembling device for disassembling a component to be disassembled from the base fixing it in a narrow working space. In this embodiment, taking the disassembly of a connector (not shown in the figure) installed between a vehicle body and a bogie as an example, a detailed description is given.

[0031] In this embodiment, the disassembling device includes a base 1, a fixed rod 2, a movable rod 3, a fixing device 4, and an operating device 5. Among them, one end of the fixed rod 2 is fixedly installed on the base 1, and the other end serves as a support point to support on a support member (not shown in the figure) during operation; one end of the movable rod 3 is movably installed on the base 1; the fixing device 4 is fixedly installed at the other end of the movable rod 3, and the fixing device 4 is connected to the component to be disassembled during operation; the operating device 5 is installed at one end of the movable rod 3 close to the base 1. Operating the operating device 5 makes the movable rod 3 move in the pulling-out direction, and then drives the component such as the connector to be disassembled to move and be pulled out through the fixing device 4.

[0032] In this embodiment, both the fixed rod 2 and the movable rod 3 are installed on the base 1. During operation, it is convenient for the operator to extend the fixing device 4 into the narrow working space. When the operator needs to disassemble the connector, he holds the base 1 by hand and can operate at a position far from the connector to drive the fixing device 4 to move, realizing the disassembly of the connector. The operation is simple and convenient, not restricted by the working space, and can ensure the operation safety of the operator.

[0033] In this embodiment, the base 1, the fixed rod 2, and the movable rod 3 are all preferably made of metal materials to ensure their structural strength. For the convenience of the operator's hand-holding, the base 1 is preferably in a disc shape, and anti-slip patterns or a number of anti-slip protrusions are provided on the outer peripheral surface of the disc shape.

[0034] In this embodiment, one end of the fixed rod 2 is fixedly installed on the base 1, and the other end serves as a support point on the support member during operation. The fixed rod 2 can be welded to the base 1. For the operation of replacing or detecting the PG and SS speed sensors of the EMU, the support member is a structural member adjacent to the speed sensor at the bottom of the vehicle body, such as the vehicle body floor.

[0035] In this embodiment, it is further preferred that the top of the fixed rod 2 has a support portion 6 adapted to the shape of the support point position of the support member, so as to achieve surface contact with the support member, which is beneficial to ensuring the stability during support and making the disassembly smoother.

[0036] For the operation of replacing or detecting the PG and SS speed sensors of the EMU, in this embodiment, preferably, the support portion 6 is in the structure of a support plate 61, and more preferably, the support plate 61 is in a disc shape and contacts the surface of the vehicle body floor to achieve support.

[0037] In this embodiment, the support portion 6 is preferably fixedly connected to the fixed rod 2 by threads, which is beneficial to replacing different support plates 61 according to the shapes of different support members. The support plate 61 can be made of a metal plate or materials such as nylon, which can avoid damaging the surface of the support member during support.

[0038] In this embodiment, for the support portion 6, another implementation manner is also provided. The support portion 6 is preferably in the structure of a suction cup, which directly uses the suction cup to adsorb and fix on the support member. It can not only ensure the support stability between the support portion 6 and the support member during operation, but also deform adaptively according to the shape of the support member, so that the suction cup effectively fits the support member, and prevent sliding between the support portion 6 and the support member, thereby ensuring the support effect without damaging the support member, and also being beneficial to expanding the use range of the device, being not restricted by the structure of the support member, and improving the versatility. Of course, the support member can also be in the structure of a rubber pad, and the rubber pad can also be appropriately deformed according to the shape of the support point, and can achieve effective support even at the curved position without damaging the support member. The support portion 6 can also directly install a suction cup on the support plate 61 to ensure the support effect without damaging the support member.

[0039] In this embodiment, one end of the movable rod 3 is movably installed on the base 1, and a fixing device 4 is fixedly installed at the other end. During operation, the fixing device 4 is used to connect with the connector to be disassembled. The operating device 5 is installed on the movable rod 3, and operating the operating device 5 makes the movable rod 3 move in the pulling-out direction (i.e., Figure 1Move in the downward direction (in the middle). Since the fixing device 4 is connected to the connector to be disassembled, the connector is driven downward and pulled out accordingly.

[0040] In this embodiment, it is further preferred that the fixing device 4 is fixed to the top of the connector by an insertion method during operation, specifically in the space between the top of the connector and the base for installing the connector. When the fixing device 4 moves in the pulling-out direction, it abuts against the top of the connector, applying a downward pressure to the connector, and thus pulling out the connector. This facilitates applying force to the connector during downward pulling, improving the disassembly speed and stability.

[0041] In this embodiment, in order to improve the contact stability between the fixing devices 4, it is preferred that the fixing device 4 includes a cylindrical main body 41 with a C-shaped cross-section, that is, the cylindrical main body 41 of the fixing device 4 is open on one side, facilitating connection with the connector. The shape of the cylindrical main body 41 is adapted to the shape of the connector body and fits on the outside of the connector body during operation. In this way, when connecting with the connector, the contact area with the connector body can be increased, which is beneficial to improving the stability during pulling. At the top of the cylindrical main body 41, there is a plug-in portion 42 extending outward. During operation, the plug-in portion 42 is inserted into the top of the connector and abuts against the top of the connector for connection. When the fixing device 4 moves in the pulling-out direction, the plug-in portion 42 applies a downward pressure to the connector, and thus the connector is pulled out.

[0042] In this embodiment, it is further preferred that the plug-in portion 42 is a triangular structure extending outward from the tops of both sides of the cylindrical main body 41. This can improve the structural strength of the plug-in portion 42, facilitate insertion into the top of the connector, and at the same time make the structure of the fixing device 4 simpler and the cost lower.

[0043] In this embodiment, in order to further improve the overall structural strength of the fixing device 4, it is preferred that a reinforcing block 8 is welded to the top of the movable rod 3, and the cylindrical main body 41 is further welded to the reinforcing block 8.

[0044] According to the structural characteristics of the connector, a retaining pin (not shown in the figure) extending to one side is installed on the connector. In this embodiment, further, a limiting groove 7 is provided on the fixing device 4. During operation, the retaining pin on the connector is snapped into the limiting groove 7 to limit the radial movement of the retaining pin on the connector. The limiting groove 7 is preferably formed by a circumferential opening on one side edge of the cylindrical main body 41 and extends to the reinforcing block 8. During operation, the operator snaps the retaining pin into the limiting groove 7 and then moves the fixing device 4 to prevent the retaining pin from retracting during downward pulling, which may affect disassembly.

[0045] In this embodiment, for the fixing device 4, another implementation manner is also provided. For a structure without a pin installed on the component, a plugging block protruding towards the component can also be simply fixed at the top of the movable rod 3 and other structures, which are in contact with the top of the component to ensure that a downward pressure is applied to the component during movement.

[0046] In this embodiment, it is preferable that the fixed rod 2 and the movable rod 3 are installed in parallel on the base 1, which is conducive to making the structure of the device simpler, easier to operate and store. Of course, they can also be installed at a certain angle, depending on the relative positions between the support member and the connector. The fixed rod 2 can be further preferably of an adjustable angle structure, and the fixed rod 2 is restricted at the adjusted angle through a locking structure. Similarly, the fixed rod 2 can also be of a length-adjustable structure, which is convenient for adjusting according to the relative positions between the support member and the connector to ensure that the fixed rod 2 can effectively support.

[0047] In this embodiment, the operating device 5 is installed near the base 1, so that the operator can operate at a position far from the top of the connector to drive the fixing device 4 to move downward to realize the disassembly of the connector, enabling the device to extend into any narrow working space for operation, avoiding the problem that the replacement or inspection operation takes a long time due to the narrow space between the vehicle body and the bogie and the inconvenient operation of pulling out the connector during the process of pulling out the connector.

[0048] In this embodiment, preferably, the operating device 5 includes a base body 51, a pulling component 52 and a locking component 53. The base body 51 is installed on the base 1. In order to improve the strength of the base body 51, the base body 51 is also fixedly connected to the fixed rod 2 on one side. The main structures of the base body 51, the pulling component 52 and the locking component 53 are all made of metal materials, and the base body 51 is welded and fixed to the base 1 and the fixed rod 2 at the same time. Of course, it can also be injection-molded with hard plastic, which is beneficial to reducing the weight of the operating device 5 while ensuring the structural strength. The movable rod 3 is movably connected to the base body 51 and the base 1. The pulling component 52 is movably installed on the movable rod 3 to drive the movable rod 3 to move along the pulling direction. The locking component 53 is movably installed on the movable rod 3 to lock or unlock the relative position between the movable rod 3 and the base body 51, that is, to adjust the distance of the downward movement of the fixing device 4 and can always be maintained at the adjusted position to avoid rebounding during the pulling-out process.

[0049] Among them, the base body 51 is generally in an L-shaped structure. The horizontal part has the same structure as the base 1 and is disc-shaped, and the vertical part is in a triangular structure. This not only has a simple structure but also is beneficial to improving the overall structural strength of the base body 51. The pulling component 52 and the locking component 53 are both installed on the base body 51.

[0050] In this embodiment, it is further preferably that the drawing assembly 52 includes a fixed handle 521, an adjusting handle 522, a spring 523 and a limiting plate 524. The spring 523, the limiting plate 524 and the fixed handle 521 are sleeved on the movable rod 3 and are movably connected to the movable rod 3. A through hole (not shown in the figure) for passing through the movable rod 3 is formed on the limiting plate 524. The fixed handle 521 is installed on one side of the base body 51. One end of the fixed handle 521 is fixedly connected to the base body 51. The adjusting handle 522 is rotatably connected to the fixed handle 521 and is simultaneously rotatably connected to one end of the limiting plate 524. The fixed handle 521 and the adjusting handle 522 are installed on the same side of the base body 51 for convenient adjustment, and the adjusting handle 522 is located below the fixed handle 521. The spring 523 is installed between the limiting plate 524 and the horizontal part of the base body 51.

[0051] During the downward drawing process of the drawing assembly 52, the operator holds the fixed handle 521 and the adjusting handle 522 and applies force to the adjusting handle 522. In this process, the limiting plate 524 is used as a lever in mechanics. One end of the limiting plate 524 connected to the adjusting handle 522 is pulled downward. Under the action of the spring 523, the limiting plate 524 is inclined with respect to the movable rod 3, so that a frictional force is generated between the through hole in the middle of the limiting plate 524 and the movable rod 3. When one end of the limiting plate 524 is pulled downward under the action of the adjusting handle 522, the movable rod 3 will be moved downward in a disguised form. Moreover, every time force is applied to the adjusting handle 522, the movable rod 3 will move up and down by a unit amplitude. After each release of the adjusting handle 522, the limiting plate 524 is reset under the action of the spring 523. Because the limiting plate 524 is in a natural state, the through hole in the limiting plate 524 will not be in inclined contact with the movable rod 3 to generate frictional force.

[0052] The locking assembly 53 includes a locking spring 531 and a dial 532. The locking spring 531 and the dial 532 are installed on the outside of the fixed handle 521 and are sleeved on the movable rod 3. An oblong limiting hole (not shown in the figure) is formed on the dial 532, and the movable rod 3 passes through the limiting hole. The locking spring 531 is installed between the fixed handle 521 and the dial 532. One end of the dial 532 is rotatably installed on the base body 51.

[0053] When the locking spring 531 is in a natural state, the dial 532 is inclined on the movable rod 3. When the dial 532 is inclined, the limiting hole will be in close contact with the movable rod 3, and locking is achieved by using frictional force. When the other end of the dial 532 is pressed downward in the direction of the locking spring 531, the dial 532 is perpendicular to the movable rod 3. At this time, the limiting hole is separated from the state of being in close contact with the movable rod 3, so that there is no frictional force between the dial 532 and the movable rod 3, and unlocking is thus achieved.

[0054] In this embodiment, above the fixed handle 521 and below the paddle 532, a limit post 533 is provided to limit the maximum pressing stroke of the paddle 532 and prevent excessive pressing of the paddle 532.

[0055] The usage steps of the device are as follows:

[0056] 1. Insert the device into the space where the connector needs to be disassembled, insert the insertion part 42 of the fixing device 4 into the top of the connector, and at the same time make the cylindrical main body 41 of the fixing device 4 fit with the main body of the connector.

[0057] 2. Support the support plate 61 at the top of the fixed rod 2 on the support member of the vehicle body.

[0058] 3. Pull out the pin on the connector and rotate the fixing device 4 to insert the pin into the limit slot 7 correspondingly.

[0059] 4. Manually operate the operating device 5 therein. Specifically, manually hold the fixed handle 521 and the adjusting handle 522, apply force to the adjusting handle 522, and repeat the operation of the adjusting handle 522 multiple times to move the movable rod 3 downward, driving the fixing device 4 and the connector to move downward, so that the connector is slowly pulled out.

[0060] The disassembling device provided by the present utility model, through the arrangement of the fixed rod 2 and the movable rod 3, and using the top of the fixed rod 2 to play a supporting role, the fixing device 4 at the top of the movable rod 3 can be effectively connected with the connector after being inserted, and the operating device 5 is used to operate at a position far from the connector to drive the fixing device 4 to move, realizing the disassembly of the connector. It not only has a simple overall structure, but also is convenient and stable to operate. The operator can easily remove the connector plug, the operation efficiency is greatly improved, and the safety of the operator can also be effectively guaranteed.

[0061] The present utility model can be inserted into any narrow working space for operation, without being restricted by the working space, avoiding the problem that the replacement or inspection operation takes a long time due to the narrow space between the vehicle body and the bogie and the inconvenient operation of pulling out the connector during the process of pulling out the connector.

[0062] The above are only the preferred embodiments of the present utility model and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present utility model, may make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes.
