Automatic leveling telescoping boom engineering vehicle with fork head

Abstract

The invention discloses an automatic leveling telescoping boom engineering vehicle with a fork head. The automatic leveling telescoping boom engineering vehicle comprises a boom assembly, a bracket, a hoisting hydraulic cylinder, a leveling device, a slewing mechanism, a hydraulic winch, a frame and an auxiliary frame, wherein the end part of the boom assembly is hinged to a fork head assembly; the fork head assembly comprises a fork, a fork head connecting frame, a rotating frame, a longitudinal hydraulic cylinder and a transverse hydraulic cylinder; the fork is arranged in a guide groove of the fork head connecting frame; the lower end of the fork head connecting frame is hinged to the rotating frame; the rotating frame is hinged to the head end of the boom assembly; one end of the longitudinal hydraulic cylinder is hinged to the rotating frame, and the other end of the longitudinal hydraulic cylinder is hinged to the boom assembly; one end of the transverse hydraulic cylinder is hinged to the rotating fame, and the other end of the transverse hydraulic cylinder is hinged to the fork head connecting frame. The automatic leveling telescoping boom engineering vehicle can work in a small hoisting space, thus improving the assembling and disassembling flexibility and efficiency, increasing the activity space of hoisting goods and improving the safety of hoisting; manual auxiliary work load is low.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to an engineering vehicle with a fork head and an automatically levelable telescopic boom. Background technique [0002] Transformer is a key component that must be used for power supply in daily life and industrial production. Due to life expectancy or other problems, transformers in hydropower plants need to be replaced frequently and regularly. The current replacement method is to use a crane for replacement. This method mainly has the following disadvantages. [0003] 1. Since the transformer is between two utility poles and there are wires above, the working space of the crane is small, and the boom and hook occupy most of the space. The activities are very limited and it is easy to touch the wires above. [0004] 2. It requires a lot of human assistance. [0005] As users pay attention to the safety of transformer replacement, it is urgent to design an engineering ...
