Problems solved by technology

The traditional docking method has technical defects. When docking, the traction pin is easy to produce a matching error with the traction saddle, which causes mechanical wear between the traction pin and the traction saddle. The height of the goose head cannot be flexibly adjusted during docking. Traction The success rate of one-time connection between the pin and the traction saddle is low, especially at night when the light is insufficient, it is even more difficult for the driver to find the correct position, and because of the single-point lap support method, the traction pin bears considerable pressure. The head, including the gooseneck, is prone to deformation

Abstract

The invention discloses a hydraulic semi-trailer goose head lifting device, comprising a cargo platform, a gooseneck seat is fixedly installed on the cargo platform, and a goose head is rotatably installed on the gooseneck seat, and the goose head is mounted on the goose head. A hydraulic push rod is hinged, and a traction pin is fixedly installed on the goose head. A rotating rod is connected, a first connecting rod is rotatably connected to the rotating rod, and the first connecting rod is rotatably connected to a first sliding block, the first sliding block is slidably connected in the first guide rail, and the first sliding block is slidably connected to the first guide rail. A first push rod is hinged on the block, the first push rod is hinged on the positioning rod, and a positioning block is fixedly installed on the positioning rod, and a reflective sticker is fixedly connected to the positioning block; The purpose of one-time connection success rate and avoiding the deformation of the goose head.

Description

technical field [0001] The invention specifically relates to a hydraulic semi-trailer goose head lifting device. Background technique [0002] Semi-trailer is a kind of heavy-duty transportation vehicle commonly used now, and it is very common. The beam of semi-trailer can be divided into gooseneck type and straight beam type. The gooseneck girder presents a "Z" shape. It has the characteristics of low center of gravity, can adapt to various models, and has the advantages of being more fuel-efficient and safer. During use, the gooseneck girder is used to dock with the traction saddle of the tractor, and the gooseneck seat is installed on the loading platform. Played a major connection role. [0003] The gooseneck of the existing semi-trailer is relatively heavy. When docking, the goose head on the gooseneck is mounted on the traction saddle so that the traction pin can be fitted into the traction saddle. The traditional docking method has technical defects. When docking, t...
