Abstract

The invention discloses a telescopic distribution rod mechanism and a concrete pump truck, which relates to the technical field of engineering machinery, and solves the technical problems of the prior art that the structural occupation space and the unfolding space of a cantilever crane are large and the distribution is not flexible. The telescopic distribution rod mechanism comprises a telescopic arm, a fixed arm and a pipeline, wherein the telescopic arm is embedded inside the fixed arm, or the telescopic arm is sleeved outside the fixed arm; the length direction of the telescopic arm is overlapped or parallel to that of the fixed arm, and the end part of the telescopic arm in the length direction can stretch out or draw back along the length direction of the fixed arm; the pipeline is formed by movably connecting two or more pipe fittings, and two pipe fittings which are arranged in a pipeline material inlet and a material outlet are respectively fixedly connected with the fixed arm and the telescopic arm; or the pipeline is a flexible pipe fitting which is made of a telescopic material. The concrete pump truck comprises the telescopic distribution rod mechanism. The telescopic distribution rod mechanism and the concrete pump truck are used for reducing the size of the distribution rod mechanism.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a telescopic distribution boom mechanism and a concrete pump truck equipped with the telescopic distribution boom mechanism. Background technique [0002] Concrete pump truck is a kind of construction machinery that transports commercial concrete to designated locations. The concrete pump truck is equipped with a boom system. The boom system is mainly used for conveying and distributing concrete. The boom system stretches the boom cylinder and rotates the turntable to deliver the concrete directly to the position pointed at the end of the boom, that is, the pouring point, through the delivery pipe attached to the boom. The conveying pipe is rigidly connected to the arm frame through the bracket, and is used for conveying concrete or other fluids. [0003] Such as figure 1 As shown, the existing concrete pump truck placing boom system consists of multi-section boo...
