Concrete mortar spurting truck

Abstract

The invention discloses a concrete mortar spurting truck comprising a truck body, a rotating system, a rotary table, a boom assembly, a hydraulic system, a pumping system, a pump pipe assembly, a rapid solidifying system, a cleaning system, an electric system, an air compressor system and a spray head assembly, wherein the truck body comprises an underpan and an auxiliary frame; the hydraulic system is connected with the rotating system, the rotating system is connected with the rotary table, the rotary table is connected with the boom assembly, and the boom assembly is connected with the spray head assembly; the rotary table is arranged in the front of the auxiliary frame, and the pumping system is arranged at the tail of the auxiliary frame and is connected with the spray head assembly through the pump pipe assembly; the air compressor system is connected with the spray head assembly; the rapid solidifying system is connected with the spray head assembly; the electric system is connected with the pumping system, the rapid solidifying system and the hydraulic system; and the rotating system, the rapid solidifying system, the cleaning system and the electric system are all arranged on the auxiliary frame. The pumping resistance of the concrete mortar spurting truck is low, the pipe distribution way of hydraulic pipelines is improved, and protecting parts such as covering parts are added, so that the protective properties are high.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a concrete spraying vehicle. Background technique [0002] The concrete shotcrete truck combines three technologies of concrete pump, air compressor system and accelerator system. It is mainly used in engineering construction in the fields of railway road tunnels, water conservancy and hydropower, subways, mine roadways, military facilities, various underground building constructions and emergency rescue. The basic process is to use hydraulic pressure to transport the ready-mixed concrete to the spray gun through the pipeline, connect compressed air and accelerator to the spray gun mouth, and then spray the concrete at high speed to the sprayed surface, and form concrete support after rapid solidification and hardening layer. [0003] There are following problems in existing shotcrete truck: [0004] 1. There are many elbows in the pumping pipeline, the pumping resistance ...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many elbows in the pumping pipeline, the pumping resistance is large, and the power consumption is high;

[0005] 2. The slurry is easy to splash when the spray truck is in operation, and the slurry adheres to the key components, which will affect the construction and reduce the service life of the components;

[0006] 3. The nozzle needs to withstand a huge reaction force. The nozzle is often connected to the hanger by bolts. The bolts are easy to loosen, causing safety hazards and affecting the service life of the nozzle;

[0007] 4. The layout of hydraulic oil pipelines is complicated, which affects the smooth flow of the pipelines, and the installation space of the pipelines is large, so the hydraulic oil pipelines cannot be well protected
