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.

Abstract

The invention discloses a sliding folding arm wet spraying machine, which comprises a vehicle frame, a driver's cab arranged on the vehicle frame in a left-biased manner, a power system is provided under the vehicle frame, an electric control system is provided above the vehicle frame, The external additive system, the hydraulic system, the air pressure system and the pumping system connected with the frame, the chassis on the right side of the cab is equipped with a construction machinery chassis, and the construction machinery chassis is equipped with a sliding folding arm frame; the sliding folding arm The lower part of the frame is connected to the sliding base with bolts, and a traveling mechanism is arranged under the sliding base, and the walking structure is arranged on the guide rail, which is fixed on the frame. The invention realizes one slip, two rotations, four twists and one stretch, realizes multi-directional control, eliminates working dead angles, improves construction quality, and increases spraying area; since workers control the spraying device through the control panel , Reduce the labor intensity of workers, reduce the dust concentration, and reduce the health hazards to construction workers.

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...
