Concrete guniting truck

Abstract

The present application discloses a concrete shotcrete vehicle, which includes an automobile chassis system, a boom system, an electrical control system, a hydraulic control system, a heat dissipation system, an additive system and a pumping system. The automobile chassis system includes a cab and a chassis. The cab is connected to the chassis for moving the chassis, the boom system, the electrical control system, the hydraulic control system, the cooling system, the additive system and the pumping system They are all arranged on the chassis so that the weight of the whole vehicle of the shotcrete vehicle is distributed symmetrically with the center line of the chassis along the advancing direction. The concrete shotcrete vehicle provided by the application has a large operating range, a compact structure and stable operation.

Description

technical field [0001] The present application relates to the technical field of engineering machinery, in particular to a concrete spraying vehicle. Background technique [0002] In tunnel engineering construction, after tunnel excavation, in order to control the appropriate release and deformation of surrounding rock stress, increase structural safety and facilitate construction, immediately after tunnel excavation, a structural layer with low stiffness and a part of the permanent bearing structure is constructed, called initial support. [0003] The initial support in tunnel engineering generally adopts shotcrete anchor support. Shotcrete anchor support refers to the joint action of high-pressure sprayed cement concrete and metal anchor rods driven into the rock formation to strengthen the rock formation, which is divided into temporary support structures and permanent support structures. [0004] Among them, the high-pressure sprayed cement concrete is completed by a c...

AI Technical Summary

Problems solved by technology

Existing concrete spraying vehicles are mainly divided into two types due to different chassis, one is self-propelled engineering chassis, the other is automobile chassis, self-propelled engineering chassis, such as crawler type, the space of self-propelled engineering chassis concrete spraying vehicle is relatively It is more abundant, and the layout of the whole machine is relatively easy, so the overall size of the whole machine is relatively small. However, due to the slow walking speed of the self-made chassis, generally no more than 15-30km / h, therefore, the transition is very inconvenient

The chassis of the automobile chassis type concrete shotcrete truck generally adopts a relatively mature automobile chassis on the market, which has a faster walking speed and faster transition. large, which is not conducive to the construction of tunnels with small and irregular sections. In addition, due to the blocking of the cab by the boom, the construction range is small when working on the front of the cab, which seriously affects the continuity of the operation. The layout is relatively difficult, which makes the whole vehicle easy to overturn during the transition and construction process, and the operation is unstable
