Multi-freedom degree self-adaption lifting obstacle crossing-type vehicle articulation mechanism

Abstract

The invention belongs to the technical field of articulated vehicle equipment for coal mines, aims at improving the adaptability of long-wheelbase heavy-type articulated vehicles to complex road conditions, and provides a multi-freedom degree self-adaption lifting obstacle crossing-type vehicle articulation mechanism. The mechanism has the functions of making front and back vehicle frames relatively veer, relatively swing and vertically lift, and includes a front connection part, a triangular lift arm, a veering articulation part, a swing articulation part and a swing shaft, the front connection part is in articulation connection with the veering articulation part through the triangular lift arm, through connection with a lift oil cylinder, the vertical-lifting function of the front connection part and the veering articulation part can be achieved, the swing articulation part is connected with the back vehicle frame through the swing shaft, horizontal swinging between the front vehicleframe and the back vehicle frame can be achieved, the veering articulation part is in articulation connection with the swing articulation part, and vertical rotation can be achieved. The mechanism can simultaneously achieve the three functions of articulated veering, horizontal swinging and vertical lifting between the front vehicle frame and the back vehicle frame, and the problem is solved thatparts of super-long articulated verticals have low adaptability to complex pavement.

Description

technical field [0001] The invention belongs to the technical field of articulated vehicle equipment for coal mines, and in particular relates to a multi-degree-of-freedom self-adaptive lifting and obstacle-crossing vehicle articulated mechanism. Background technique [0002] Coal mine underground roadway space is narrow and the road surface conditions are bad, especially during the relocation of the fully mechanized mining face, a large number of heavy equipment needs to be installed or withdrawn, and the weight of a single piece can reach more than 80 tons, so the transportation of heavy equipment is very easy to damage the road surface , leading to the extreme deterioration of the road surface, and the high cost and long cycle of maintaining the road surface seriously affect the mine production efficiency. The existing three-axis or four-axis articulated auxiliary transport vehicles for coal mines, especially the ultra-long heavy vehicles with a body of more than 10 meter...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problem that the existing ultra-long and heavy-duty articulated transport vehicles for mining use have a long body and a large wheelbase, which leads to the poor passability of the vehicle under road conditions such as uneven road surface and sharply changing slope points, the present invention further provides a multi-degree-of-freedom Adaptive lifting obstacle-surmounting vehicle articulation mechanism to improve the adaptability of long-wheelbase heavy-duty articulated vehicles to complex road conditions
