The invention relates to the technical field of semitrailers, and provides semitrailer traction equipment which comprises a tractor and a chassis and further comprises two moving seats, a limiting assembly, a semi-traction seat, a one-way clamping assembly, an anti-falling assembly and an oil feeding mechanism, the two moving seats are arranged on the chassis in a sliding mode, the limiting assembly is used for limiting the moving seats, and the semi-traction seat is arranged on the chassis. The number of the semi-traction seats is two, a main plate is arranged between the two moving seats, the semi-traction seats are arranged on the main plate in a sliding mode, the one-way clamping assembly is used for limiting one-way movement of the semi-traction seats and clamping traction pins, the oil feeding mechanism is used for oiling the surfaces of the semi-traction seats, and the oil feeding electric cylinders are arranged on the moving seats. A piston is arranged at the output end of the oil feeding electric cylinder and arranged in the injection cylinder in a sealed and sliding mode. By means of the technical scheme, the problems that in the prior art, when a traction base and a traction pin are connected, the error-tolerant rate is low, the connection strength is low, and abrasion is prone to occurring between the traction base and the traction pin are solved.
本发明涉及半挂车技术领域,提出了一种半挂车牵引设备,包括牵引车和底盘,还包括移动座、限位组件、半牵引座、单向卡紧组件、防脱落组件和送油机构,移动座设置有两个,移动座滑动设置在底盘上,限位组件用于对移动座进行限位,半牵引座设置有两个,两个移动座之间设置有主板,半牵引座滑动设置在主板上,单向卡紧组件用于限制半牵引座单向移动,对牵引销进行卡紧,送油机构用于对半牵引座表面进行涂油,送油电动缸设置在移动座上,送油电动缸的输出端设置有活塞,活塞密封滑动设置在注射筒的内部。通过上述技术方案,解决了现有技术中对牵引座和牵引销进行连接时容错率较低,连接强度较低,并且牵引座和牵引销之间容易磨损的问题。
