Meanwhile, in order to avoid the problem that when the gearbox is disassembled, the second support table 5 is in spherical hinge with the adjusting component 4, so that the gearbox is easy to incline when being subjected to a little external force, and normal disassembling operation is influenced, an auxiliary support component 7 is further arranged between the first support table 3 and the second support table 5, each auxiliary support component 7 comprises four telescopic rods 71 and springs 72 sleeved on each telescopic rod 71, the four telescopic rods 71 are distributed at 90 degrees along the axis of the first support table 3 between every two adjacent telescopic rods 71, the four telescopic rods 71 are located on one side, away from the axis of the adjusting shaft 41, of the support piece 6, limiting rings 711 are fixedly connected to each telescopic rod 71, the limiting rings 711 are located at two ends of each telescopic rod 71, and the springs 72 are located between. The spring 72 will give the second support table 5 a supporting force and thereby fix the relative position of the second support table 5.

One end of the telescopic rod 71 is hinged to the first supporting table 3 through a ball joint, the other end of the telescopic rod is hinged to the mounting block 73 through a ball joint, one end, far away from the telescopic rod 71, of the mounting block 73 is connected with a roller 74 in a rotating mode, meanwhile, a second sliding groove 75, which is used for enabling the roller 74 to be embedded, is fixedly connected to one side, facing the first supporting table 3, of the second supporting table 5, the cross section of the second sliding groove 75 is in a C shape, and an inlet 751 (refer to fig. 1) used for enabling the roller 74 to slide into the second sliding groove 75. Before the use, directly slide the gyro wheel 74 in the second spout 75 from import 751 and can, when dismantling, the staff can rotate the angle of second brace table 5 as required, and gyro wheel 74 also slides in second spout 75 this moment, and the operation is more nimble.

Referring to fig. 2, in order to avoid that the gearbox falls off from the second support table 5 when the gearbox is transported away by the moving trolley 1 after the gearbox is disassembled, a kidney-shaped groove 52 is formed in the second support table 5, four kidney-shaped grooves 52 are formed in the kidney-shaped groove 52, two adjacent kidney-shaped grooves 52 are arranged at 90 degrees along the axis of the second support table 5, and the extension line of the length direction of each kidney-shaped groove 52 passes through the axis of the second support table 5. Third sliding grooves 521 are formed in the two sides of each kidney-shaped groove 52 along the length direction of the kidney-shaped groove, a second sliding block 522 is connected to each kidney-shaped groove 52 and the third sliding grooves 521 communicated with the kidney-shaped groove 52 in a sliding mode, a fixing bolt 53 in threaded connection with the second sliding block 522 is arranged on the upper surface and the lower surface of the second sliding block 522 in a penetrating mode, and a rotating button 54 is fixedly connected to one end, close to the first supporting table 3, of the fixing bolt 53, is perpendicular to the second supporting table 5. After the gearbox is placed on the second support table 5, the worker can directly slide the relative position of the second sliding block 522 in the third sliding groove 521, so that the axis of the threaded hole on the fixing bolt 53 and the gearbox coincides, and then the fixing bolt 53 is connected to the gearbox through rotating the rotating button 54.

In conclusion, when the automobile gearbox lifting device is used, an automobile is lifted to a proper height through the lifting machine, the distance between the second supporting table 5 and the first supporting table 3 is adjusted to be the shortest distance through the adjusting assembly 4, the second sleeve 62 slides into the first sleeve 61, then the movable trolley 1 is pushed to the position below the gearbox to be disassembled, and a worker can directly disassemble the gearbox. Just can directly place the gearbox one end of dismantling on second supporting bench 5 after dismantling gearbox one end, the during dismantlement can rotate second supporting bench 5 and change the bank height of second supporting bench 5 as required, directly revolve twist the handle 43 when the height of second supporting bench 5 is finely tuned to needs can. After the disassembly is completed, a worker can directly slide the position of the second sliding block 522 in the third sliding groove 521, so that the axis of the threaded hole of the fixing bolt 53 and the axis of the threaded hole of the gearbox are overlapped, then the rotating button 54 is screwed, the second supporting table 5 and the gearbox are fixed together through the fixing bolt 53, then when the second sleeve 62 slides, one end, far away from the first sleeve 61, of the second sleeve 62 is embedded into the limiting groove 51, the first sliding block 621 is embedded into the appropriate clamping groove 612, and the second supporting table 5 is prevented from being unstable in fixation.
