A telescopic multifunctional intelligent operating arm

Abstract

The invention provides a telescopic multifunctional intelligent operation arm. A single-acting oil cylinder is used for power drive for telescopic operation of suspension arm bodies of four joint arm bodies. The basic arm body, namely a large arm body does not move. The telescopic second joint arm body, the telescopic third joint arm body and the telescopic fourth joint arm body are driven by the telescopic oil cylinder and a third arm body extend-out steel wire rope, a fourth arm body retraction steel wire rope and a third arm body retraction and fourth arm body extension steel wire rope in a linkage manner, wherein the third arm body extend-out steel wire rope, the fourth arm body retraction steel wire rope and the third arm body retraction and fourth arm body extension steel wire rope are arranged in the suspension arm bodies. In the extend-out and retraction change routes of the steel wire ropes, the increased length and the reduced length of the steel wire ropes are changed synchronously, so that the steel wire ropes are in the tightened state all the time, and suspension arm body telescopic stability is guaranteed. The mechanical operation arm has the multi-direction freedom degree and the action in any position can be achieved. The mechanical operation arm is a carrier and multiple work devices can be additionally arranged on the hand portion and used for achieving various kinds of operation such as loading a concrete gun, a high-pressure water gun, a camera and a bridge detection probe.

Description

technical field [0001] The invention relates to the technical field of booms, in particular to a telescopic multifunctional intelligent operating arm. Background technique [0002] In the prior art, self-propelled cranes are widely used in various construction operations due to their maneuverability and flexible transition characteristics. With the increase of lifting tonnage, the load of each executive system will increase to varying degrees, and at the same time the structural size and range of motion of each mechanism will increase accordingly; among them, in order to increase the operating range and height of the crane, the existing crane Most of the booms are multi-stage telescopic booms, and a single oil cylinder is used to drive the multi-section boom to expand and contract through the rope row, so as to control the extension and retraction of the boom through the expansion and contraction of the oil cylinder. The distribution of the rope rows of the existing boom de...

AI Technical Summary

Problems solved by technology

The distribution of the rope rows of the existing boom device is relatively chaotic, and the stability is poor. At the same time, the volume of the boom is greatly increased, and the mobility of use is correspondingly reduced. Moreover, when the existing boom is pushing objects, the clamps at the end of the boom are all It is fixed and can only be pushed in one direction, which greatly affects the use effect and range of the boom
