Concrete distributor with arm support capable of both horizontal rotation and pitching movement

Abstract

The invention provides a concrete distributor with an arm support capable of both horizontal rotation and pitching movement. The concrete distributor comprises a tower body support and an arm support system connected in parallel with a concrete pumping pipeline. The head end of the arm support system is rotationally connected with the tower body support in horizontal rotation manner via a first horizontal rotation mechanism. The concrete pumping pipeline comprises a feeding pipe and a discharge nozzle. The arm support system is formed by the tail-to-head connection of a large arm, a middle arm and a small arm, which are in relative movement to one another. The tail end of the large arm is rotationally connected with the head end of the middle arm in horizontal rotation manner via a second horizontal rotation mechanism. The tail end of the middle arm is rotationally connected with the head end of the small arm via a pitching mechanism. The tail end of the small arm is connected with the discharge nozzle. Since the arm support system is capable of both horizontal rotation and pitching movement, the concrete distributor incorporates the horizontal operation and the vertical operation, integrates the advantages of the prior two types of concrete distributors, improves the single operation mode of the prior concrete distributor, and substantially overcomes the problems of the prior two types of concrete distributors.

Description

technical field [0001] The invention relates to a concrete distribution construction machine. Background technique [0002] The concrete placing machine is the distributing equipment for concrete pouring at the end of the concrete pumping pipeline. It can effectively improve the efficiency of concrete pouring, improve the quality of concrete pouring, and promote civilized construction. It is an indispensable supporting equipment in concrete pumping operations. [0003] The known concrete placing machine can be divided into two types according to the action type of the boom: one is that the boom can extend forward and backward, and the boom can pitch in the vertical plane between them, but there is no relative movement in the horizontal plane, and the rotation of the whole machine in the horizontal plane There is only one mechanism, which is located at the connection between the root of the jib and the support on the tower body; the other type is that the whole machine has tw...

Problems solved by technology

[0005] In order to overcome the deficiencies of the existing distribution machines, the present invention provides a distribution machine that combines horizontal rotation and pitching movement of the boom, to solve the problem that the boom of the traditional distribution machine cannot perform two movements of pitching in the vertical plane and rotating in the horizontal plane at the same time question
