The lower frames 3 are arranged in one-to-one correspondence with the upper frames 2, one ends of the lower frames 3 are hinged to the upper frames 2, and the lower frames 3 can swing in the vertical direction.

Referring to fig. 3 to 6, the lower frame 3 is provided with a clamp 31 and a clamping cylinder 32, the clamp 31 is provided at the bottom of the lower frame 3, the clamping cylinder 32 is provided at the middle of the lower frame 3, and the clamping cylinder 32 drives the clamp 31 to perform clamping and releasing actions.

The clamping cylinder 32 is arranged in the mounting position and on the slide 34, the piston rod of the clamping cylinder 32 extending downwards through the slide 34 towards the support 33. A driving member 35 and a first elastic member 36 are disposed between the sliding member 34 and the supporting member 33, and the driving member 35 sequentially includes a first connection portion 351, a stop portion 352, a sleeve portion 353, and a second connection portion 354 from top to bottom. A threaded hole is provided in the first connection portion 351, a threaded post is provided at the end of the piston rod of the clamping cylinder 32, and the first connection portion 351 is screwed onto the end of the piston rod. The diameter of the stop portion 352 is larger than that of the sleeving portion 353, the first elastic member 36 is sleeved on the sleeving portion 353, and the first elastic member 36 is elastically abutted against the bottom wall of the mounting position and the stop portion 352, namely, is elastically abutted between the stop portion 352 and the supporting member 33. The second connection portion 354 passes downward through the support 33 for connection with the clamp 31. Since the second connection portion 354 is spaced apart from the jig 31 by a long distance, it is preferable that the driving lever 37 is connected between the second connection portion 354 and the jig 31, and the driving lever 37 extends in the vertical direction and is disposed coaxially with the second connection portion 354.

The bus lifting frame with the detection device further comprises a control unit and the detection device, wherein the detection device comprises a sensing plate 4, a bracket (not shown in the figure) and a sensor 5, the sensing plate 4 is arranged on the outer side of a stop part 352 of the driving piece 35, and the sensing plate 4 can move up and down synchronously along with the driving piece 35. The sensing plate 4 extends along the moving direction thereof, the sensing plate 4 is provided with two through holes 41 along the extending direction thereof, and the two through holes 41 are arranged along the moving direction of the sensing plate 4 and are spaced by a preset distance. The via hole 41 may be a round hole or a waist hole, and when the via hole is a waist hole, the length direction of the waist hole is parallel to the vertical direction.
