Concrete placing boom

Abstract

The invention discloses a concrete placing boom, which comprises a walking base, a main column, a main revolving arm, an auxiliary revolving arm, a pipeline system, an end telescopic pipeline, a mainarm support leg, an auxiliary arm support leg and a control system. The concrete placing boom provided by the invention is characterized in that the walking base is utilized for satisfying the movement requirement of the whole machine; the two-stage revolving arms are utilized for rotating the end telescopic pipeline to the appointed pouring position; the telescopic ability of the end telescopic pipeline is utilized for ensuring the end telescopic pipeline to be withdrawn back synchronously during the pouring process; the distance between the discharge port of the end telescopic pipeline and the liquid level of concrete is enabled to be constant; and the main arm support leg and the auxiliary arm support leg are synchronous in adjustment to the height of the walking base for maintaining the horizontal level of the two-stage revolving arms. The concrete placing boom has the advantages of beautiful structure, light weight, high control precision, autonomous walking, and the like, and isapplicable to intelligent pouring occasions with complicated ground environment.

Description

technical field [0001] The invention relates to the technical field of concrete pouring systems, in particular to a concrete distributing machine. Background technique [0002] In the pouring process of steel shell concrete immersed tube, the quality of concrete pouring is high, and the working environment is not convenient for workers to enter, so it is necessary to develop a concrete distribution machine with a constant distance between the injection port and the concrete liquid surface, and the whole machine needs The structure is light while remaining stable, enabling trouble-free operation on the pouring site. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art in the pouring process of steel shell concrete immersed tubes, which require high concrete pouring quality and the working environment is not convenient for workers to enter, and provide a concrete placing machine, Th...
