Self-propelled small wet spraying vehicle

Abstract

The invention discloses a self-propelled small wet spraying vehicle, and belongs to the field of concrete wet spraying vehicles. The self-propelled small wet spraying vehicle comprises a small wet spraying device, a self-propelled chassis and a vehicle head. The small wet spraying device is installed at the rear end of the self-propelled chassis. The vehicle head is installed at the front end of the self-propelled chassis. The vehicle head comprises an engine compartment and a driving cab. The self-propelled chassis is provided with direction wheels and driving wheels. The small wet spraying device comprises a control panel, a pump chamber, a pumping system and a floodlight. The self-propelled chassis is installed on a towed small wet spraying vehicle instead, the driving vehicle head is additionally installed, and therefore the self-propelled small wet spraying vehicle can enter a construction site in a self-propelled mode, complete concrete spraying and be driven away from the construction site; meanwhile, labor intensity is reduced, construction efficiency is improved, the self-propelled small wet spraying vehicle achieves major functions of a self-propelled wet spraying mechanical hand, but the price of the self-propelled small wet spraying vehicle is much lower than that of the wet spraying mechanical hand.

Description

technical field [0001] The invention relates to a self-propelled small wet spray vehicle, which belongs to the field of concrete wet spray vehicles. Background technique [0002] Shotcrete is an important process in tunnel construction. There are two types of sprayed concrete: dry and wet. Due to the disadvantages of large dust, large amount of shot rebound, poor concrete density and low strength in the process of dry shotcrete, it is generally not allowed to be used in modern tunnel construction. In modern wet spraying concrete construction, two types of wet spraying equipment are mainly used, one is a towed small wet spraying vehicle without a driving chassis, and the other is a concrete wet spraying manipulator with a driving chassis. The towed small wet spraying vehicle has a low degree of automation and must rely on the traction of other machinery to realize the transfer of work and departure. Its work efficiency is low, and the preparation time before work and after ...

AI Technical Summary

Problems solved by technology

The towed small wet spraying vehicle has a low degree of automation and must rely on the traction of other machinery to realize the transfer of work and departure. Its work efficiency is low, and the preparation time before work and after work is long, which seriously affects the efficiency of tunnel construction.

The concrete wet spraying manipulator has a high degree of automation and comes with a driving chassis and a spraying manipulator, but its equipment is expensive, and the equipment cost is 40-50 times that of a towed small wet spraying car, and the operation and maintenance costs are also very high, requiring professional Operators come to complete the work, so the penetration rate of this equipment is very low
