Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

a man car with a monorail suspension shock absorption system is shown in figures 1 and 2 and comprises a man car body 1, a bearing trolley 2, a suspension beam body 4, a shock absorber fixing frame 5 and a spring damping shock absorber 6; the bearing trolley 2 is connected to a suspension beam body 4 through a plane hanging shaft 3, and a pair of shock absorber fixing frames 5 are symmetrically welded on two sides of the suspension beam body 4 respectively; the spring suspension 15 and the spring damping shock absorber 6 are arranged in the shock absorber fixing frame 5; the spring damping shock absorber 6 is composed of a damping oil cylinder 7 and a spring 8, a connecting pin hole is formed in the top end of the damping oil cylinder 7 and is connected and fixed with a spring suspension frame 15 through a penetrating pin shaft 9, a top pin hole (17) shown in figures 3 and 4 is connected and fixed, the lower end of the spring damping shock absorber 6 is connected and fixed with a supporting plate 10 in a shock absorber fixing frame 5 through 3 uniformly distributed bolts 11 and nuts 12, and the supporting plate 10 plays a role in supporting the spring suspension frame 15, the spring damping shock absorber 6 and the whole man car. As shown in fig. 3 and 4, the spring suspension 15 is provided with a protection plate 16 at the middle part, and the damping oil cylinder 7 of the spring damping shock absorber 6 is fixedly protected by the protection plate 16; two pin holes 18 are respectively arranged at the lower ends of two sides of the spring suspension 15, and four lifting points 13 on the man-car body 1 are connected with the pin holes at the lower end of the spring suspension 15 through four pin bolts 14. In the entire connection structure, the spring hanger 15 and the spring damper 6 are installed in the damper mount 5, so that the shock generated from the human vehicle body 1 is transmitted to the spring damper 6 through the spring hanger 15, and the spring damper 6 absorbs the shock generated from the human vehicle body 1.

The utility model discloses to the inherent characteristic of colliery monorail system people car, design and made and be exclusively used in the people car that has shock-absorbing function who increases people car automobile body stability and take the travelling comfort based on monorail system. Because the suspension beam body 4 and the shock absorber fixing frame 5 are welded to form an integral structure, the spring damping shock absorber 6 and the man-car body 1 are connected through the spring suspension 15 to form a novel suspension shock absorption system. Therefore, in the process of advancing the man car, the vertical up-and-down vibration generated by the man car body 1 is transmitted to the four spring damping shock absorbers 6 by the spring suspension 15 to be absorbed, so that the vibration generated by the man car body 1 is reduced to the minimum; when the vehicle body shakes left and right, the spring damping shock absorber 6 can also reduce the large-amplitude left and right shaking generated by the man vehicle body 1, and when the vehicle body ascends and descends, the spring damping shock absorber 6 can weaken the large-amplitude swinging generated by the man vehicle body 1, so that the running stability and riding comfort of the monorail crane man vehicle are realized.
