Multipurpose connecting rod working device

Abstract

The invention discloses a multipurpose connecting rod working device. Parallel movable arms are arranged at two sides of a rack; one end of each of the movable arms is hinged with the rack, and the other end of each of the movable arm is hinged with a part of an end actuator; one end of a front pull rod is hinged with another part of the end actuator, the other end of the front pull rod is hinged with one end of a front rocker, and the other end of the front rocker is hinged with the middle part of the movable arm; the middle part of the front rocker is hinged with a piston rod of an end actuator cylinder; a cylinder sleeve of the end actuator cylinder is hinged with the front part of the movable arm; one end of a rear pull rod is hinged with the movable arm, the other end of the rear pull rod is hinged with one end of a rear rocker, and the other end of the rear rocker is hinged with the rack; the middle part of the rear pull rod is hinged with the piston rod of a movable arm cylinder; and the cylinder sleeve of the movable arm cylinder is hinged with the rack. The multipurpose connecting rod working device disclosed by the invention has the advantages of multiple purposes, flexibility in operation, high carrying capacity, large excavation force, good translational motion property, easiness in manufacture, assembling and control, and motion decoupling.

Description

technical field [0001] The invention relates to a working device, in particular to a connecting rod working device of construction machinery. Background technique [0002] The connecting rod working device is the most commonly used working device, especially in the application of construction machinery, so the innovation of this working device has always been the key to the innovation of construction machinery. Chinese patent ZL00230230.6 relates to a snow pushing device used in conjunction with a loader. It is an independent snow pushing device that realizes its snow removal function by exchanging positions with the loader bucket. Chinese patent ZL201020198273.9 relates to a forward-rotating eight-link working device mechanism of a loader, which can only complete independent loading functions, but cannot independently complete such as natural disasters (earthquakes, floods, landslides, etc.) when there are boulders on the road , mud and trapped vehicles need to be cleared ...

AI Technical Summary

Problems solved by technology

Chinese patent ZL201020198273.9 relates to a forward-rotating eight-link working device mechanism of a loader, which can only complete independent loading functions, but cannot independently perform such functions as natural disasters (earthquakes, floods, landslides, etc.) when there are boulders on the road , mud and trapped vehicles need to be cleared to the roadside in a timely manner such complex tasks

However, the movement and power requirements of functions such as bulldozing and transporting are significantly different from those of simple loading functions, so it is difficult for the mechanism to realize the task of clearing obstacles with a large load of tens of tons, and it cannot meet the requirements of both loading and loading. It can meet the movement and power requirements of various functions such as bulldozing and transportation

In addition, such a mechanism does not adopt a separable design, resulting in a large cumulative error of the mechanism, making it difficult to manufacture and assemble

Also, in such a mechanism, the boom cannot reach a horizontal position, which is not conducive to pushing obstacles
