Description

Technical Field

[0001] This utility model relates to the field of vehicle jacking machines, and more particularly to a fixed vehicle jacking machine. Background Technology

[0002] A bogie lifting machine is a specialized lifting device used for the maintenance of rail transit vehicles. It is mainly used for lifting operations of vehicles such as subways, EMUs, and trams to facilitate bogie replacement, undercarriage component maintenance, or overall vehicle maintenance. Fixed bogie lifting machines are the core equipment for rail transit vehicle maintenance. They are mainly used to lift subway and light rail vehicles as a whole or in sections to facilitate bogie replacement, undercarriage component maintenance, and comprehensive inspection. They are widely used in depots, maintenance bases, and manufacturing plants and are an important infrastructure to ensure the safe operation of rail transit.

[0003] Traditional fixed frame lifting machines are relatively cumbersome to adjust the size of the support plate during use and cannot be applied to most frame types. Furthermore, after prolonged use, the frame of a traditional fixed frame lifting machine is prone to deformation under heavy pressure, which can endanger the safety of workers.

[0004] Therefore, those skilled in the art have provided a fixed vehicle jacking machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixed vehicle support machine. A sliding block under the support arm can slide along a groove on the fixed base plate. During operation, starting the second motor controls the movement of the movable connecting seat. Simultaneously, the support arm tilts at a certain angle via the rotating seat and the movable connecting seat, eventually being stopped by the groove. This effectively improves the support force of the equipment and prevents the main body from tilting due to the weight of the vehicle frame during operation, thus ensuring the safety of the workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fixed vehicle jacking machine includes a frame. An extension mechanism is provided at the lower end of the inner wall of the frame. The extension mechanism includes a lifting block slidably connected to the inner wall of the frame.

A fourth extension block is fixedly connected to one side of the outer wall of the first toothed column. A first extension block is fixedly connected to one side of the outer wall of the third toothed column.

[0008] The lower surface of the frame is provided with a support mechanism, which includes a support frame fixedly connected to the lower surface of the frame, a second motor fixedly connected to the lower end of the inner wall of the support frame, a second threaded shaft fixedly connected to the output end of the second motor, a movable connecting seat rotatably connected to the upper end of the outer wall of the second threaded shaft, support arms rotatably connected to both sides and the rear end of the outer wall of the movable connecting seat, a rotating seat rotatably connected to the lower surface of the support arm, and a sliding block rotatably connected to the lower surface of the rotating seat.

[0009] Through the above technical solution, the sliding block under the support arm can slide along the sliding groove on the fixed base plate. When working, starting the second motor can control the movement of the movable connecting seat. While the movable connecting seat is moving, the support arm can be tilted at a certain angle through the rotating seat and the movable connecting seat, and finally it will be stopped by the sliding groove. This can effectively improve the support force of the equipment, effectively prevent the main body of the equipment from tilting due to the weight of the frame when the equipment is working, and effectively ensure the safety of the staff.

[0010] Furthermore, a support base plate is fixedly connected to the lower surface of the second motor, a fixed base plate is fixedly connected to the outer wall of the support base plate, and a snap-fit ​​block is fixedly connected to the side of the support arm near the middle.

[0011] Through the above technical solution, the support range of the third extension block, the fourth extension block, the second extension block, and the first extension block can be controlled by the knob, and the second, third, and fourth extension blocks can be reinforced by the first, third, and second reinforcing columns. This mechanism allows the device to adapt to more types of vehicle frames and can effectively increase the support area.

[0012] Furthermore, the upper surface of the fixed base plate is provided with multiple sliding grooves, the sliding block slides inside the sliding grooves, and the middle of the outer wall of the support frame on both sides and the rear end is provided with inclined grooves, and the snap-fit ​​block is slidably connected to the inclined grooves.

[0013] The above technical solution allows the support arm to tilt at a certain angle by sliding the sliding block inside the groove.

[0014] Furthermore, a limiting plate is rotatably connected to the upper surface of the second threaded shaft, and the second threaded shaft meshes with the movable connecting seat;

[0015] The above technical solution allows the movable connecting seat to move via the second threaded shaft.

[0016] Furthermore, a reinforcing plate is fixedly connected to the lower surface of the lifting block, and a knob is rotatably connected to the lower surface of the reinforcing plate;

[0017] The above technical solution allows the support range of the third expansion block, the fourth expansion block, the second expansion block, and the first expansion block to be controlled by a knob.

[0019] The above technical solution can improve the strength of the equipment by using the first, second, and third reinforcing columns.

[0020] Furthermore, the spur gear is fixedly connected to the knob, and the spur gear meshes with the first toothed column, the third toothed column, and the second toothed column;

[0021] Through the above technical solution, the support range of the fourth extension block, the second extension block, and the first extension block can be expanded or reduced by the meshing of the spur gear with the first, third, and second toothed columns.

[0022] Furthermore, a first motor is fixedly connected to the upper surface of the frame, and a first threaded shaft is fixedly connected to the output end of the first motor. A threaded hole is opened on the upper surface of the lifting block, and two counterweight columns are provided at the rear end of the upper surface of the lifting block.

[0025] 1. The present invention proposes a fixed vehicle support machine, in which the sliding block under the support arm can slide along the sliding groove on the fixed base plate. When working, the second motor can be started to control the movement of the movable connecting seat. While the movable connecting seat is moving, the support arm can be tilted at a certain angle through the rotating seat and the movable connecting seat, and finally it will be stopped by the sliding groove. This can effectively improve the support force of the equipment, effectively prevent the main body of the equipment from tilting due to the weight of the vehicle frame during operation, and effectively ensure the safety of the workers.
