The invention mainly relates to the field of engineering trailers, in particular to a mechanism for assisting a vehicle in walking. The mechanism comprises a hydraulic motor, a frame and a roller, the roller is arranged at the output end of the hydraulic motor, and the hydraulic motor is fixed to the frame; tires are mounted on the rear side of the frame; the roller and the tire are arranged in a tangent and abutting mode. The tires are located on the left side and the right side of the rear half portion of the frame. And the rollers and the hydraulic motors are correspondingly arranged in two groups and are respectively connected with the tires on the left side and the right side. Universal wheels are arranged at the front part of the frame; the two hydraulic motors are respectively connected with a control system of the aerial work trailer and can be controlled independently or simultaneously. According to the structure, the problem that the trailer needs to walk by itself to a certain degree is solved, and steering adjustment can be conducted; and the rollers are not in contact with the tires when not working, so that the influence on the movement of the trailer is avoided.
本发明主要涉及工程拖车领域,具体的说是一种助力车辆行走的机构。本机构包括液压马达、车架和滚筒,所述滚筒设置于所述液压马达的输出端,所述液压马达固定于所述车架上;所述车架后侧安装有轮胎;所述滚筒与所述轮胎相切紧靠安置。所述轮胎位于所述车架后半部的左右两侧;所述滚筒与所述液压马达相应设置有两组,分别左右两侧的轮胎相接。所述车架前部设置有万向轮;两液压马达分别于高空作业拖车的控制系统连接,能够单独或同时控制。本结构解决了拖车需要一定程度的自行走的问题,并能够进行转向调节;滚筒在不工作时与轮胎不相接触,从而避免对拖车的移动产生影响。
