In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] The present embodiment relates to a device for adjusting and supporting the gear box of the railcar, which can solve the problems of instability and easy falling off caused by the lack of special supporting tool during the disassembly and assembly of the bogie, and solve the problem of being unable to adjust the height when installing the gear box boom adjustment pad.

[0026] Based on the above design idea, an exemplary structure of the device for adjusting and supporting the gear box of the railcar of the present embodiment is shown in Figures 1-4 The device mainly includes a lower table 6, the lower table 6 is provided with a telescopic load-bearing rod 3 at the bottom, the lower table 6 is provided with a fork arm frame 5 at both sides, one end of the fork arm frame 5 is connected to the side surface of the lower table 6, the other end is connected to an upper panel 1, the bottom of the upper panel 1 is fixedly connected to the bottom of the telescopic load-bearing rod 3, a pair of fork arm frames 5 are provided with shaft holes, a rotatable manual rotating shaft 4 is installed in the shaft holes, and the manual rotating shaft 4 is overlapped with the side wall surface of the telescopic load-bearing rod 3.

[0027] By being provided with the front and rear fork arm frames 5, one end of which is connected with the lower platform 6 and the other end of which is connected with the upper panel 1 and the bottom of the upper panel 1 is fixed with the bottom of the telescopic load-bearing rod 3, a stable support structure is built to ensure the stability of the whole device; by being provided with the shaft hole on the fork arm frame 5 and the rotatable manual rotating shaft 4 is installed, and the manual rotating shaft 4 is overlapped with the side wall surface of the telescopic load-bearing rod 3, the height of the telescopic load-bearing rod 3 is adjusted by rotating the manual rotating shaft 4 to meet the support requirements of different heights.

[0028] Specifically, the wheels include a pair of universal wheels 7 and a pair of directional wheels 8, the pair of universal wheels 7 is installed at the bottom left end of the lower platform 6, and the pair of directional wheels 8 is installed at the bottom right end of the lower platform 6, by being provided with the pair of universal wheels 7 and the pair of directional wheels 8, the device can flexibly turn and ensure the stability of straight movement during movement, and the device can be quickly moved to the support position of the gear box of the rail car.

[0029] The number of telescopic load-bearing rods 3 is two, and they are staggered. By being provided with two staggered telescopic load-bearing rods 3, the upper panel 1 can be uniformly stressed when supporting the gear box, and the support stability and reliability of the device to the gear box are improved.

[0030] The top plate of the upper panel 1 is inclined, and it is lowered from left to right, and the upper panel 1 is bonded with the rubber pad 2 by glue, and the rubber pad 2 is located at the right side of the top end of the upper panel 1, by setting the upper panel 1 as an inclined surface with left high and right low, the gear box bottom can be better received, and by bonding the rubber pad 2 on the upper panel 1, the friction with the gear box is increased, the gear box is prevented from sliding during support, and at the same time, the buffering protection effect is achieved to avoid damage to the gear box.

[0031] When the device for supporting the gear box of the rail car is used, the universal wheels 7 and the directional wheels 8 are used to move the device to the appropriate position, the upper panel 1 is aligned with the gear box plane, and then the universal wheels are locked.

[0032] According to the actual height requirement of the gear box, the telescopic load-bearing rod 3 is raised by manually rotating the manual rotating shaft 4 clockwise, and after contacting the bottom surface of the gear box, it continues to rise, and after the gear box is horizontal, the operation is stopped, and the work is carried out after confirming the support stability. Since the manual rotating shaft 4 is overlapped with the side wall surface of the telescopic load-bearing rod 3, when the manual rotating shaft 4 is rotated, the telescopic load-bearing rod 3 will be stretched and contracted, so that the height of the upper panel 1 is accurately adjusted.

[0033] When the height is adjusted to the appropriate height, the gear box is located on the rubber pad 2 of the upper panel 1, and at this time the weight of the gear box is transmitted to the telescopic load-bearing rod 3 and the lower platform 6 through the upper panel 1, and then supported on the ground by the wheels.

[0034] Subsequently, the bogie is disassembled / erected, and after the operation is completed, the device is moved to a designated position, and then the rotating shaft is rotated to restore the original state, and is used next time.

[0035] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
