Abstract

The invention discloses a traction device convenient for a trailer, which relates to the field of mobile traction devices for trailers. The trailer traction device comprises a traction fixing frame, atelescopic frame, a front cross beam piece, a traction piece rotating seat, a traction fixing piece, a rotating driving piece and an anti-collision buffer piece, and has the beneficial technical effects that a certain safety distance can be generated between the trailer traction device and a trailer body during traction, and the traction fixing piece can be automatically driven to be unfolded towards the outer end. The number of the traction fixing frames is two. The two ends of a telescopic frame are connected with the two traction fixing frames in a matched mode. The front end of the telescopic frame is connected to a front cross beam piece in a matched mode. The traction piece rotating seat is movably connected to the front cross beam piece; the traction fixing piece is connected to the traction piece rotating seat in a matched mode, one ends of the two rotating driving pieces are arranged on the two traction fixing frames respectively, the other ends of the two rotating driving pieces are movably connected with the two ends of the traction piece rotating seat respectively, and the two anti-collision buffer pieces are symmetrically arranged at the lower end of the traction piece rotating seat.

Description

technical field [0001] The invention relates to the field of mobile traction devices for trailers, in particular to a traction device for trailers. Background technique [0002] The patent number is CN201921146645.0 telescopic trailer traction frame, a telescopic trailer traction frame, which is characterized in that: a horizontal balanced outer tube is installed under the longitudinal traction main pipe, and the left and right outer parts are installed in the balanced outer tube. The outer ends of the left and right horizontal expansion tubes are equipped with connectors; the front and rear surfaces of the left and right ends of the balance outer tube are respectively opened with two longitudinal through holes arranged left and right. On the back, there are multiple groups of locking through holes corresponding to the longitudinal through holes; the upper part of the longitudinal traction main pipe is equipped with a connecting ring. It solves the problem that the fixed le...
