When the gearbox is assembled, the gearbox is firstly hoisted on the supporting platform, then the gearbox reworking supporting auxiliary tool and the gearbox are pushed to the lower part of the vehicle body together, the gearbox is lifted to a proper height by the aid of the jacking mechanism, the assembly of the gearbox is completed, finally the height of the supporting platform is lowered by the aid of the jacking mechanism, and the gearbox reworking supporting auxiliary tool is removed from the bottom of the vehicle. The step of disassembling the gearbox is the reverse of the step of assembling the gearbox and will not be described here in detail. The gearbox can be pushed to advance through the travelling mechanism, the gearbox position adjustment and centering during assembly are facilitated, the jacking mechanism has a mechanical lifting function, the gearbox is not lifted by a person for operation, the labor intensity and the operation difficulty are greatly reduced, and the safety is improved.
Furthermore, a plurality of supporting and protecting rods are mounted at the top of the travelling mechanism, and are positioned beside the jacking mechanism and below the horizontal sliding rail; the top end of the supporting protection rod is movably sleeved with a sleeve, and the top end of the sleeve is fixedly connected with the horizontal sliding rail. When climbing mechanism suddenly became invalid, supporting platform can fall under the action of gravity of self and gearbox, but can be withstood by supporting the fender rod after falling very short distance to the security has been improved. In addition, the supporting and protecting rod is connected with the horizontal sliding rail through the movable sleeve, and the stability of the horizontal sliding rail is also facilitated.
Specifically, the traveling mechanism is composed of a base, rollers installed below the base and a locking mechanism used for locking the rollers. The jacking mechanism is composed of a jack, and the top end of a piston rod of the jack is fixedly connected with the horizontal sliding rail. The traveling mechanism and the jack are common structures or components, and are not described in detail herein.
Furthermore, the horizontal sliding rail and the supporting platform are provided with positioning mechanisms which are matched with each other to fix the supporting platform relative to the horizontal sliding rail, so that the gearbox and the supporting platform are prevented from suddenly sliding on the horizontal sliding rail to influence the normal assembly and disassembly of the gearbox. Specifically, the positioning mechanism is composed of a limiting bolt, a limiting through hole vertically penetrating through the supporting platform and a positioning screw hole arranged on the horizontal sliding rail. And the limiting bolt downwards penetrates through the limiting through hole and is screwed into the positioning screw hole, so that the supporting platform can be stabilized on the horizontal sliding rail.
Further, for convenient operation, the lateral part of supporting platform is equipped with the handrail.
The transmission case reworking support auxiliary tool is simple in structure, low in cost and convenient to operate, and can effectively reduce the labor intensity of personnel and improve the reworking efficiency.

The figures are numbered: 1. a traveling mechanism; 2. a jacking mechanism; 3. a horizontal slide rail; 4. a support platform; 5. a frame; 6. supporting the guard bar; 7. a sleeve.
Detailed Description
The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.
Example 1:
this embodiment provides a gearbox reworking support assists utensil to effectively reduce personnel intensity of labour, improve the security of reworking efficiency and operation.
As shown in fig. 1, the gearbox rework supporting auxiliary tool of the present embodiment is composed of a traveling mechanism 1 and a jacking mechanism 2 located on the traveling mechanism 1, and a supporting platform 4 is movably mounted at the top end of the jacking mechanism 2 through a horizontal sliding rail 3.
The walking mechanism 1 comprises a base, a roller arranged below the base and a locking mechanism for locking the roller, wherein the roller is formed by combining a universal roller and a directional roller, and the locking mechanism is arranged at the directional roller; the jacking mechanism 2 is composed of a jack, and the top end of a piston rod of the jack is fixedly connected with the horizontal sliding rail 3; a frame 5 and a plurality of supporting and protecting rods 6 are fixedly arranged on the base, the jack is positioned in the frame 5, the top end of a piston rod of the jack extends upwards out of the frame 5, and the supporting platform 4 is positioned above the frame 5; the supporting and protecting rod 6 is positioned around the jacking mechanism 2 and below the horizontal sliding rail 3; the top end movable sleeve that supports protective rod 6 is equipped with sleeve 7, the top and the horizontal sliding rail 3 fixed connection of sleeve 7.
