Concrete spreader for construction

Abstract

The invention provides a concrete spreader for construction, and belongs to the technical field of construction machinery. The concrete spreader is used for solving the problems that an existing spreader is low in degree of freedom and inconvenient to store and spreads materials in a larger range. The concrete spreader comprises a guide rail and a material spreading pipeline assembly, wherein a walking assembly and a winding machine are arranged on the guide rail; a main rotating seat is hinged to the walking assembly; a bottom frame is fixed at the upper end of the main rotating seat; a rotating seat is arranged at the upper end of the bottom frame; a rotating frame is rotationally arranged at the upper end of the rotating seat; a material spreading rod frame and a counterweight rod frame are hinged to the two sides of the rotating frame respectively; a plurality of folding hydraulic cylinders are hinged between the rotating frame and the material spreading rod frame and between the rotating frame and the counterweight rod frame; the upper end of the material spreading pipeline assembly is connected with a flexible connecting pipe; and the end part of the flexible connecting pipe is connected with a material spreading pipe. The concrete spreader is convenient to install, fix, move and walk, and can be used for spreading concrete in different positions and in a larger area range; and the main rotating seat can rotate, the material spreading rod frame and the counterweight rod frame can be stored, the occupied space is small, and transportation and storage are convenient.

Description

technical field [0001] The invention belongs to the technical field of construction machinery and relates to a concrete distribution machine for construction. Background technique [0002] The concrete placing machine is the terminal equipment for pumping concrete, and its function is to send the pumped concrete through the pipeline to the formwork of the component to be poured. [0003] General classification: hydraulic distributing machine, manual distributing machine; according to different pouring environments and individual requirements of concrete construction, various models such as internal crawling type, walking type, ship-mounted type, and manual type have been designed for users, forming the current The HG series concrete placing machine with the most complete specifications in the world; the main structure includes a bolt, a stand, and the base is a fixed part, on which the upper part is connected to the upper part through a slewing bearing. The upper cross bar ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing concrete placing machines are pulled by manpower, which can make the entire rotary part rotate 360 ​​degrees, and the operation is complicated. At the same time, the two balance arms are always kept in the unfolded state, which takes up a lot of space, which is not conducive to storage and transportation, and its outriggers are fixed. After that, it can no longer be moved, but can only be rotated, and concrete distribution cannot be carried out on a larger scale.
