A rubber pad is installed on the telescopic end of the hydraulic rod 6 .
[0035] During maintenance, the vehicle is driven on two carriages, and the hydraulic rod 6 is used to lift the vehicle, so that it is convenient for personnel to pass through the maintenance space and to maintain the bottom of the vehicle.
[0036] Both travel frames include a middle frame 1, and both ends of the middle frame 1 are symmetrically installed with wedge frames 2; the wedge frames 2 are arranged according to the figure 1 and 2 The way in the middle is arranged at the end of the middle frame 1, and the vehicle can be conveniently placed on the middle frame 1 through the wedge frame 2, which is convenient for the subsequent use of the hydraulic rod 6 to lift the vehicle.
[0037] The top surface of the guide rail 3 is provided with a groove, and the first adjustment mechanism includes a first bidirectional screw rod 31 rotatably installed in the groove. The bottom of the wedge frame 2 is fixedly installed, the first two-way screw rod 31 is driven by a first adjusting motor 33; the first adjusting motor 33 is installed on the upper side of the guide rail 3 through a bracket, and a bevel gear 34 is installed in the middle of the first two-way screw rod 31 , the driving end of the first regulating motor 33 is also installed with a bevel gear 34, and the two bevel gears 34 are meshed with each other. The bottom wall of the wedge frame 2 is provided with a through groove matching the guide rail 3, and the slider 32 is fixed in the through groove.
[0038] According to the specific vehicle model, the distance between the two carriages is adjusted by the first adjustment mechanism. The adjustment process is as follows: the first adjustment motor 33 drives the two bevel gears 34 to mesh with each other, thereby controlling the first bidirectional screw 31 to rotate, and the first adjustment motor 33 drives the two bevel gears 34 to mesh with each other. The bidirectional screw rod 31 and the slider 32 are threadedly installed, and the threaded block 32 is fixed to the bottom of the wedge frame 2. Therefore, when the first bidirectional screw rod 31 rotates, the wedge frame 2 and the entire travel frame can be controlled to move, thereby realizing driving. Shelf spacing adjustment.
[0039] The intermediate frame 1 is provided with a cavity 5, and the second adjustment mechanism includes a second bidirectional screw rod 8 rotatably installed inside the cavity 5. The second bidirectional screw rod 8 is driven by a second adjustment motor 17, and the second bidirectional screw rod 8 A sliding seat 9 is installed with symmetrical threads on both ends of the sliding seat 9, a rotating seat 10 is hingedly installed on the upper side of the sliding seat 9, the hydraulic rod 6 is fixed on the top of the rotating seat 10, and the rotating seat 10 is hingedly installed with the sliding seat 9 through the rotating shaft. A worm wheel 11 is installed, a horizontal plate is installed on the outer side of the sliding seat 9 , and a worm 12 is rotatably installed on the horizontal plate.
[0040] A linkage rod is installed between the two worms 12 on one side of the same intermediate frame 1. The linkage rod has a square tube 16 and two square rods 15. Both ends of the square tube 16 are slidably installed with the square rods 15. One end of the square rod 15 away from the square tube 16 is mounted and fixed to the roller shaft of the worm 12, a first gear 14 is installed between one of the square rods 15 and the worm 12, and the first gear 14 is also installed on the driving end of the rotating motor 13, and the two are installed. The first gears 14 mesh with each other.
[0041] The intermediate frame 1 is provided with a chute at the lower side of the cavity 5 , and the bottom of the sliding seat 9 is provided with a sliding bar matching the chute.
[0042] The second adjusting motor 17 is installed inside the cavity 5, and the second gear 18 is installed at the driving end of the second adjusting motor 17, and the second gear 18 is also installed in the middle of the second bidirectional screw 8. Two second gears 18 mesh with each other.
[0043] Adjust the distance between the two hydraulic rods 6 in each intermediate frame 1 according to the specific vehicle model. The adjustment process is as follows: the second adjustment motor 17 drives the two second gears 18 to mesh with each other, controls the second bidirectional screw 8 to rotate, and the second The two-way screw 8 is threadedly installed with the two sliding seats 9, so the sliding seats 9 can be controlled to approach or move away from each other, thereby controlling the rotating seat 10 and the hydraulic rod 6 to adjust the position, so that the distance between the two hydraulic rods 6 can be adjusted according to the vehicle model. suitable location.
[0044] After the position of the hydraulic rod 6 is appropriate, it needs to be rotated so that its telescopic end can be vertically telescopic, so as to lift the vehicle.
[0045] The rotation process of the hydraulic rod 6 is as follows: the rotary motor 13 drives the two first gears 14 to mesh with each other, controls the worm 12, the square rod 15, and the square tube 16 to rotate at the same time, the worm 12 and the worm wheel 11 mesh with each other, and the rotating seat can be controlled by the rotating shaft 10 and the hydraulic rod 6 are rotated so that the hydraulic rod 16 can be rotated to Image 6 state, the hydraulic rod 6 can be extended to figure 1 state in order to jack up the vehicle.
[0046] The two worms 12 are linked by a linkage rod composed of a square tube 16 and two square rods 15, that is, when one worm 12 rotates, the worm 12 on the other side can also rotate, and the sliding seat 9, the rotating seat 10 and the hydraulic When the position of the rod 6 is adjusted, the sliding cooperation between the square rod 15 and the square tube 16 is used to make the linkage rod retractable and maintain the linkage effect of the two worms 12 .
[0047] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. The equivalent replacement or change of the inventive concept thereof shall be included within the protection scope of the present invention.
