Automatic spraying wall concrete wet spraying machine based on chain transmission and work method thereof

Abstract

The invention relates to an automatic spraying wall concrete wet spraying machine based on chain transmission and a work method thereof. The wet spraying machine comprises a wet spraying machine hopper device, an annular transmission chain rail assembly, an automatic material taking device and an automatic spraying mechanism, wherein the annular transmission chain rail assembly is connected with awet spraying machine base through a liftable support frame. A whole spraying device assembly does arc-shaped movement on the annular transmission chain rail assembly through being driven by a first chain wheel; and the distance and the angle between a spray head and the surface of a laneway are regulated through a servo electric cylinder and a servo rotating platform according to signals such aslaneway surface distances and angles fed back by a laser sensor, so that automatic and uniform concrete spraying is realized.

Description

technical field [0001] The invention relates to a chain-driven automatic spraying wall concrete wet spraying machine and a working method thereof, belonging to the field of mine concrete spraying devices. Background technique [0002] Shotcrete in mines can prevent the spalling and weathering of rocks in main roadways, detours, crossings, underground parking lots, machine repair stations and water pump rooms. Depending on the rock formation conditions, the thickness of shotcrete can vary between 5-30mm. The safety of well construction and subsequent construction operations plays a vital role. [0003] At present, before coal mines use a spraying machine to carry out concrete spraying operations, the spraying machine must be placed according to the needs and possibilities of the construction site, and the mobile trolley will transport the dry concrete to the job site, and the wet spraying machine will be used for mixing. Mixing materials, using manual spraying operation on t...

Problems solved by technology

[0003] At present, before coal mines use a spraying machine to carry out concrete spraying operations, the spraying machine must be placed according to the needs and possibilities of the construction site, and the mobile trolley will transport the dry concrete to the job site, and the wet spraying machine will be used for mixing. Mixing materials, using manual spraying operation on the surface of the roadway, this operation is not only inefficient, but also causes uneven thickness of concrete on the surface of the roadway due to manual spraying, and even some parts are not covered by concrete, and the environment inside the roadway is relatively harsh , there is a lot of dust, and it also has certain damage to the health of workers.
