Description

Technical Field

[0001] The utility model relates to the technical field of bogie maintenance, in particular to a bogie maintenance workbench. Background Art

[0002] The bogie is a core component of rail transit vehicles, primarily consisting of a frame, wheelsets, axlebox, spring damper, traction device, and basic brake system. It not only bears the weight of the entire carriage but also provides guidance, support, and shock absorption, ensuring the safe and smooth operation of the train.

[0003] The existing authorization announcement number is CN218364631U, which is a maintenance platform for train bogie maintenance. It includes a maintenance platform body, an adjustment mechanism and a fixing mechanism. The maintenance platform body includes a load-bearing platform and two lifting and flipping structures. The two lifting and flipping structures are respectively bolted and slidably connected to the two sides of the load-bearing platform. The adjustment mechanism is rotatably connected to the inside of the load-bearing platform. The top of the adjustment mechanism is bolted to the right lifting and flipping structure, which can flip various models of bogies, making it convenient for workers to disassemble and repair the parts thereon.

[0004] In actual use, after the bogie is placed on the maintenance workbench, the wheelset needs to be disassembled first, and then the frame together with the other components installed on the frame is lifted and turned over according to the disassembly requirements, so that the maintenance personnel can disassemble and repair the other components on the frame. However, after the connection between the wheelset and the frame is released, due to the lack of a limiting structure for the wheelset, the wheelset can easily roll during the process of lifting the frame, which not only brings inconvenience to the work of the maintenance personnel, but also there is a possibility that the wheelset will crush the feet of the maintenance personnel, posing a certain safety risk.

[0005] To this end, the present application specifically proposes a bogie maintenance platform to solve the above technical problems. Utility Model Content

[0006] The main purpose of the utility model is to solve the above-mentioned shortcomings and provide a bogie maintenance workbench that can impose a limit on it during the process of removing the wheelset to prevent the wheelset from rolling when the frame is lifted.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The bogie maintenance platform includes a platform body, a slot group provided on the platform body, and a frame lifting and turning machine provided on both sides of the slot group, and further includes:

[0009] Multiple positioning mounting blocks are symmetrically arranged on both sides of the slot group; multiple electric telescopic rods have fixed ends arranged on the positioning mounting blocks, telescopic ends facing the slot group, perpendicular to the extension direction of the slot group, and parallel to the top surface of the platform body; multiple clips are fixedly arranged on the telescopic ends of the electric telescopic rods, used to abut the outer side of the wheelset and limit the rolling of the wheelset.

[0010] Furthermore, the clamping member includes a pressure plate for abutting against two sides of the wheelset and an arc-shaped baffle provided on both sides of the pressure plate for abutting against the circumferential outer walls of the rollers on both sides of the wheelset.

[0011] Furthermore, an anti-slip rubber is fixedly provided on the contact surface between the pressure plate and the wheelset.

[0012] Furthermore, the number of the positioning mounting blocks is eight, and every two positioning mounting blocks on the same side of the slot group form a group. Two electric telescopic rods are fixed on each group of positioning mounting blocks, and the clamping piece is simultaneously fixed to the telescopic ends of the two electric telescopic rods in the same group.

[0013] Furthermore, inserting strips are fixedly provided on both sides of the clamping member, and a socket slidably plugged with the inserting strips is fixedly provided on the platform body, and the inserting strips and the socket are parallel to the electric telescopic rod.

[0014] Furthermore, the socket includes a slot with an open top and passing through both ends and mounting edges fixedly arranged on both sides of the slot. The insertion strip includes an inserting portion slidably inserted into the slot and a connecting plate arranged at the end of the inserting portion for connecting to the card connector.

[0015] The beneficial effects of the present invention are as follows:

[0016] The utility model controls the extension of the electric telescopic rod to drive the clamping parts at its telescopic end to clamp the two sides of the wheelset, thereby limiting the wheelset. When the connection between the wheelset and the bogie is released and the frame of the bogie is clamped and lifted and flipped using the frame lifting and flipping machine, due to the limiting effect of the clamping parts on the wheelset, during the process of frame lifting, even if a certain contact is made with the wheelset and a horizontal thrust is applied, the wheelset cannot roll on the platform body, thereby preventing the rolling wheelset from crushing the feet of the maintenance personnel, thereby improving the convenience and safety of maintenance.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the utility model provides a bogie maintenance workbench, comprising:

[0025] The platform body 1, the slot group 2 opened on the platform body 1 and the frame lifting and turning machine 3 arranged on both sides of the slot group 2, also include: multiple positioning mounting blocks 4, symmetrically arranged on both sides of the slot group 2; multiple electric telescopic rods 5, the fixed ends of which are arranged on the positioning mounting blocks 4, the telescopic ends facing the slot group 2, and perpendicular to the extension direction of the slot group 2, and parallel to the top surface of the platform body 1; multiple clips 6, fixedly arranged at the telescopic ends of the electric telescopic rods 5, for abutting the outer side of the wheelset 7 and limiting the rolling of the wheelset 7.

[0026] When in use, first align the limit stop ring of the wheelset 7 on the bogie 11 with the slot group 2 and move it to the position corresponding to the clamping part 6 on the platform body 1, then control the electric telescopic rod 5 to extend so that the clamping part 6 at the telescopic end clamps the two sides of the wheelset 7, forming a limit for the wheelset 7, and then release the connection between the wheelset 7 and the bogie 11, and then operate the frame lifting and turning machine 3 to clamp the frame of the bogie 11, and lift and turn it. Due to the limiting effect of the clamping part 6 on the wheelset 7, during the frame lifting process, even if there is a certain contact with the wheelset 7 and a horizontal thrust is applied, the wheelset 7 cannot roll on the platform body 1, thereby preventing the rolling wheelset 7 from crushing the feet of the maintenance personnel, thereby improving the convenience and safety of maintenance.

[0027] When the wheelset 7 is completely separated from the frame, the electric telescopic rod 5 is controlled to retract, driving the clamping part 6 to no longer contact the wheelset 7, thereby releasing the limit on the wheelset 7. The maintenance personnel can easily push the wheelset 7 away from the platform body 1 and proceed to the next process.

[0028] It is worth noting that the main function of the frame lifting and turning machine 3 is to clamp the frame of the bogie 11 and drive it to lift and turn. It is a common existing technology used in this field, so it will not be described in detail, and the structure and shape are not described in detail in the accompanying drawings.

[0029] In one embodiment, the clamping member 6 includes a pressure plate 61 for abutting against two sides of the wheelset 7 and arc-shaped baffles 62 provided on both sides of the pressure plate 61 for abutting against the circumferential outer walls of the rollers on both sides of the wheelset 7 .

[0030] With this design, the pressure plates 61 on both sides of the wheelset 7 cooperate with each other under the pushing action of the electric telescopic rod 5 to clamp the wheelset 7. Under the action of the friction resistance between the wheelset 7 and the pressure plates 61, the wheelset 7 is difficult to roll, forming a preliminary limit for the wheelset 7; while the pressure plates 61 abut against both sides of the wheelset 7, the arc-shaped baffles 62 are covered on the circumferential outer walls of the rollers on both sides of the wheelset 7 to prevent the wheelset 7 from rolling, forming a further limit for the wheelset 7.

[0031] In one embodiment, an anti-skid rubber 8 is fixedly provided on the contact surface between the pressure plate 61 and the wheelset 7 .

[0032] This design can increase the friction coefficient between the wheelset 7 and the pressure plate 61. On the basis of equal clamping force, it increases the friction resistance between the wheelset 7 and the pressure plate 61, reduces the possibility of relative sliding between the wheelset 7 and the pressure plate 61, and thus improves the reliability of the limiting function of the pressure plate 61.

[0033] In one embodiment, the number of positioning mounting blocks 4 is eight, and every two positioning mounting blocks 4 on the same side of the slot group 2 form a group. Two electric telescopic rods 5 are fixed on each group of positioning mounting blocks 4, and the clamping parts 6 are simultaneously fixed to the telescopic ends of the two electric telescopic rods 5 in the same group.

[0034] With this design, each clamping member 6 is pushed by two electric telescopic rods 5 , thereby improving the stability of the clamping member 6 during movement and the accuracy of docking with the wheelset 7 .

[0035] In one embodiment, inserting strips 9 are fixedly provided on both sides of the clamping member 6 , and a socket 10 slidably plugged with the inserting strips 9 is fixedly provided on the platform body 1 . The inserting strips 9 and the socket 10 are parallel to the electric telescopic rod 5 .

[0036] With this design, when the electric telescopic rod 5 drives the clamping part 6 to move, the insertion strip 9 slides along the socket 10 to provide guidance for the extension and retraction process of the electric telescopic rod 5, further improving the smoothness of the movement process of the clamping part 6 and the accuracy of docking with the wheelset 7.

[0037] In one embodiment, the socket 10 includes a slot 101 with an open top and passing through both ends, and mounting edges 102 fixedly arranged on both sides of the slot 101. The insertion strip 9 includes an inserting portion 91 that is slidably inserted into the slot 101 and a connecting plate 92 arranged at the end of the inserting portion 91 for connecting to the card connector 6.

[0038] With this design, the plug-in portion 91 is slidably inserted into the slot 101, forming a guiding effect on the extension and retraction process of the electric telescopic rod 5. The opening at the top of the slot 101 avoids blocking the connecting plate 92, so that the entire plug-in strip 9 can slide freely on the socket 10.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, "multiple" means more than two. Furthermore, the technical solutions of the various embodiments may be combined with each other, but this must be based on the premise that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
