Modularized mechanical arm, hoisting system and posture adjusting method

Abstract

The invention provides a modular mechanical arm, a hoisting system and a posture adjusting method. The modular mechanical arm, the hoisting system and the posture adjusting method are used for solvingthe problem that the posture of an object to be hoisted cannot be adjusted in real time in the prior art. The invention provides the modular mechanical arm which comprises a mounting table, a base, alifting arm, a first driving piece, a load-bearing inhaul cable mechanism and a posture adjusting mechanism. The base is rotatably mounted on the mounting table; a cab and a controller are arranged on the base; the lifting arm is of a telescopic structure; the lower end of the lifting arm is hinged onto the base; the first driving piece drives the lifting arm to turn over; the load-bearing inhaulcable mechanism comprises a load-bearing inhaul cable, a load-bearing inhaul cable driving piece, a top pulley block and a load-bearing lifting hook; and the posture adjusting mechanism comprises a first posture adjusting inhaul cable, a first posture adjusting driving piece, a first middle pulley block and a first posture adjusting lifting hook.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a modular mechanical arm, a hoisting system and a posture adjustment method. Background technique [0002] Cranes are used for various road rescue operations. There are two types of crane structures. One is to directly use the crawler chassis, and the boom is fixed on the crawler chassis. This structure is specially designed and manufactured, and its existence cost high, and prone to the problem of dumping; another is to install the mechanical arm on the chassis of the car. The problem with this structure is that the mechanical arm is installed locally, resulting in partial stress concentration on the chassis of the car. The chassis is easily damaged during use. The self-weight of the car chassis is used as a counterweight structure, but the car is supported by tires. At the same time, due to the existence of the shock-absorbing structure, it is easy to fluctuate up and down, resulting in s...
