the lifting mechanism is mounted on top of the vehicle body 11. The damping mechanism comprises a wheel connecting frame, a bearing support part 2 and a spring damper 6; the wheel connecting frame is fixed on the vehicle body 11; the end part of the wheel connecting frame is provided with a bearing support part 2; the bearing support 2 is sleeved on the axle 3; one end of the spring shock absorber 6 is fixed on the vehicle body, and the other end is fixed on the wheel connecting frame.
The wheel connecting frame comprises a lower wheel connecting frame 4 and an upper wheel connecting frame 5;
two ends of the bearing support part 2 are fixed between the lower wheel connecting frame 4 and the upper wheel connecting frame 5 and can move up and down in a small range, and a bearing is arranged in the bearing support part 2 to realize the rotation of the axle 3. The spring damper 6 is fixed to the upper wheel link 5.
When the trolley wheels 1 meet a convex road condition, the spring shock absorbers 6 are contracted, the lower wheel connecting frame 4 and the upper wheel connecting frame 5 rotate with a small amplitude along with the fixed point of the trolley body 11, so that the bearing supporting piece 2 rises, and the trolley body is kept relatively stable. When the wheel 1 encounters a concave road condition, the spring damper 6 extends, so that the bearing support member 2 descends to a smaller extent, thereby achieving the stability of the vehicle body.
As shown in fig. 2 and 3, the lifting mechanism comprises a top plate 7, a jacking bracket 8, a hydraulic cylinder 9, a bottom end rail 12 and a top end rail 13; the jacking bracket 8 is slidably mounted between the bottom end rail 12 and the top end rail 13; the bottom end rail 12 and the hydraulic cylinder 9 are fixed on the vehicle body 11; the telescopic rod of the hydraulic cylinder 9 is fixed on the jacking bracket 8, and the hydraulic cylinder 9 is used for driving the jacking bracket 8 to reciprocate between the bottom end rail 12 and the top end rail 13; the top plate 7 is fixed to the top end rail 13.
