Building construction concrete spraying unit with protection mechanism

Abstract

The invention belongs to the technical field of building construction equipment, and particularly relates to a building construction concrete spraying unit with a protection mechanism. The building construction concrete spraying unit with a protection mechanism aims at solving the problems that a pipeline of an existing concrete spraying unit is prone to blockage, the protection effect is poor, the use effect of the concrete spraying unit is poor, and when a spraying pipe is blocked, the concrete spraying unit needs to be shut down and unblocked, and use is not facilitated. The building construction concrete spraying unit with the protection mechanism comprises a bottom plate; a conveying pipe is located above the bottom plate and is connected with a fixed box; an anti-blocking assembly is installed in the fixed box; a first spraying pipe and a second spraying pipe are installed on the conveying pipe; spraying heads are installed at the tail ends of the first spraying pipe and the second spraying pipe; and a cleaning assembly is mounted on each spraying head. According to the concrete spraying unit, the interior of the conveying pipe is cleaned through the anti-blocking assembly, blockages blocked in the spraying pipes are loosened through a vibration assembly, materials in the spraying heads are removed through the cleaning assemblies, the first spraying pipe and the second spraying pipe are standby for each other, and the protection effect and the use effect of the concrete spraying unit are improved.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a concrete injection unit for building construction with a protective mechanism. Background technique [0002] The concrete spraying unit is the concrete spraying machine, which uses compressed air to continuously transport the concrete along the pipeline and spray it onto the construction surface. It can be divided into two categories: dry spraying machine and wet spraying machine. It is sprayed out after mixing with pressure water at the nozzle, and the latter is conveyed by pneumatic or concrete pump to spray out the concrete mixture through the nozzle, which is widely used in the lining construction of underground engineering, shafts, tunnels, culverts, etc.; [0003] In the Chinese patent application number 2019221111464, a construction concrete sprayer is disclosed, including a bottom plate, a mixing box is fixedly connected to the middle of the top ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a concrete spraying unit for building construction with a protective mechanism, which can stir the internal concrete through the stirring rod and the spiral stirring shaft, so as to prevent the internal concrete from solidifying, which is helpful for the conveying and spraying of materials, through The ejector rod and the hinged seat can adjust the spraying angle of the delivery pipe, which is convenient for spraying at different angles according to the needs. The first spraying pipe and the second spraying pipe are used as spares for each other, so there is no need to stop temporarily to clear the first spraying pipe. It ensures the continuous spraying operation and significantly improves the use effect and efficiency of the concrete spraying unit. By setting the anti-blocking component, it can effectively clean the inside of the conveying pipe, prevent the inside of the conveying pipe from clogging, and improve the protection of the concrete spraying unit. Effect and the overall use effect, by setting the vibration component, the impact ball repeatedly hits the first injection pipe, so that the first injection pipe vibrates continuously, and can loosen the blockages blocked in the first injection pipe, and play a role in dredging. The dredging effect and The dredging efficiency is good, which helps to improve the overall use effect. By setting the cleaning component, the cleaning block reciprocates in the spray head to remove the materials attached or blocked in the spray head, and realize the cleaning of the spray head. Operation, play a protective role, solve the problem that the pipes of the existing concrete injection unit are easy to block, the protection effect is not good, the use effect of the concrete injection unit is not good, and when the injection pipe is blocked, it is necessary to shut down and clean the injection pipe , and continue the injection operation after the blockage removal is completed, which is not conducive to use and is not conducive to improving operational efficiency.
