Wet spraying machine with sliding foldable arm

Abstract

The invention discloses a wet spraying machine with a sliding foldable arm. The wet spraying machine comprises a frame, a driving cab is arranged on the frame in a left offset manner, a power system is arranged below the frame, an electric control system, an external additive system, a hydraulic system, an air pressure system and a pumping system which is connected with the frame are arranged above the frame, an engineering mechanical chassis is arranged on the frame on the right side of the driving cab, a sliding foldable arm support is arranged on the engineering mechanical chassis, the lower portion of the sliding foldable arm support is connected with a sliding base through bolts, a travelling mechanism is arranged below the sliding base and on a guide rail, and the guide rail is fixed on the frame. By the aid of the wet spraying machine with the sliding foldable arm, one slide, two rotations, four folding and one extension are realized, multidirectional control is realized, dead working angles are eliminated, construction quantity is improved, spraying area is enlarged, labor intensity of workers is reduced since the workers control the spraying device by controlling an operation panel, dust concentration is lowered, and risks to health of construction workers are reduced.

Description

technical field [0001] The invention relates to the field of engineering construction machinery, in particular to a slipping folding arm wet spraying machine for concrete wet spraying machines used in tunnel engineering, highway engineering, side slope and other initial support constructions. Background technique [0002] Among the existing engineering construction machinery, the concrete sprayer is a relatively common construction machinery. The working principle of the concrete spraying machine is to use compressed air to transport the pre-mixed concrete mixture to the nozzle of the spraying machine through the pipeline, and form a material beam after being mixed with an accelerator. On the sprayed surface, the quick-setting agent makes the concrete set and harden quickly, thus forming a concrete support layer. Shotcrete technology is widely used in various construction fields because of its simple process and economical cost. [0003] Most of the sprayers currently used...

AI Technical Summary

Problems solved by technology

[0003] Most of the jet machines currently used are small hand-held, and the supporting parts are scattered, which is inconvenient for transportation. It has poor passability on steep, potholed and uneven roads.

This kind of wet spraying machine can't control the quality of sprayed concrete well, the concrete has a high rebound rate, the construction quality is poor, and the efficiency is low; in addition, the spraying head is operated manually, the labor intensity of the workers is high, the spraying produces a lot of dust, and the construction environment is harsh , have a great impact on the health of workers

[0004] The publication number is CN102287206A, the patent document of the invention and creation name is a concrete wet spraying machine, which discloses a technical scheme of a wet spraying machine, which has defects such as a small area of ​​sprayed concrete in one parking, and dead angles.
