Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

The AGV shock-absorbing and buffering mechanism and the lifting mechanism of the present utility model will be introduced in detail below with reference to the accompanying drawings.

As shown in FIG. 1, an AGV structure with shock absorption and lifting mechanism includes a shock absorption mechanism, a lifting mechanism and a vehicle body 11; the shock absorption mechanism is installed at the position of the wheel 1 of the vehicle body 11;

The lift mechanism is installed on the top of the vehicle body 11 . The damping mechanism includes a wheel connecting frame, a bearing support 2 and a spring shock absorber 6; the wheel connecting frame is fixed on the vehicle body 11; the end of the wheel connecting frame is provided with a bearing support 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 includes a lower wheel connecting frame 4 and an upper wheel connecting frame 5;

Both ends of the bearing support 2 are fixed between the lower wheel connecting frame 4 and the upper wheel connecting frame 5 and can keep a small range of up and down movement. The bearing support 2 is equipped with bearings to realize the rotation of the axle 3 . The spring damper 6 is fixed to the upper wheel connecting frame 5 .

When the trolley wheel 1 encounters a bumpy road condition, the spring shock absorber 6 contracts, the lower wheel connecting frame 4 and the upper wheel connecting frame 5 rotate with the fixed point of the vehicle body 11 to a small extent, so that the bearing support 2 rises, Thereby maintaining the relative stability of the vehicle body. When the wheel 1 encounters a concave road condition, the spring shock absorber 6 is extended, so that the bearing support 2 is lowered to a small extent, thereby realizing the stability of the vehicle body.

As shown in Figures 2 and 3, the lifting mechanism includes a top plate 7, a jacking bracket 8, a hydraulic cylinder 9, a bottom rail 12, and a top rail 13; the jacking bracket 8 is slidably installed between the bottom rail 12 and the top rail 13 The bottom 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 to drive the jacking bracket 8 between the bottom rail 12 and the top rail 13 Reciprocating movement between; the top plate 7 is fixed on the top rail 13.

The jack-up bracket 8 includes a rotating support rod 14 and a fixed support rod 15 that are rotatably connected; the bottom rail 12 and the top rail 13 are provided with sliding grooves; the two ends of the rotating support rod 14 are slidably installed in the sliding groove; The two ends of the cylinder are respectively fixed on the bottom rail 12 and the top rail 13; the telescopic rod of the hydraulic cylinder 9 is fixed on the rotating support rod.

When the AGV needs to achieve the lifting function, the hydraulic cylinder 9 shrinks, and at the same time, the connecting rod 10 is pulled close to the hydraulic cylinder 9, so that the jacking bracket 8 moves to the fixed end along the bottom rail 12 and the top rail 13. At this time, due to the jacking bracket 8 Since the angle with the vehicle body 11 increases, the roof 7 rises.

When the AGV needs to realize the lowering function, the hydraulic cylinder 9 is extended, and at the same time, the connecting rod 10 is pushed away from the hydraulic cylinder 9, so that the jacking bracket 8 is away from the fixed end along the bottom rail 12 and the top rail 12. The angle of the vehicle body 11 is reduced, so the roof 7 is lowered.
