Automatic spraying wall climbing robot for concrete wet spraying machine and working method thereof

Abstract

The invention discloses an automatic spraying wall climbing robot for a concrete wet spraying machine and a working method thereof. The automatic spraying wall climbing robot comprises a vehicle frame, an electromagnetic adsorption system, and a traveling mechanism, wherein a vertical column is arranged on the upper part of the vehicle frame, and the top of the vertical column is connected with aspraying head through a horizontal rotation mechanism and a pitch angle adjustment mechanism; the electromagnetic adsorption system is arranged at the lower part of a chassis of the wall climbing robot and used for providing adsorption force when the wall climbing robot works, and the traveling mechanism is arranged at the bottom of the vehicle frame and used for driving the vehicle frame and devices on the upper part of the vehicle frame to move integrally. The automatic spraying wall climbing robot can be adsorbed on a mine support wire mesh, the adsorption force is automatically adjusted, traveling resistance of the wall climbing robot is reduced, and driving safety the wall climbing robot is ensured.

Description

technical field [0001] The invention relates to an automatic spraying wall-climbing robot for a concrete wet spraying machine, which belongs to the field of mining 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 the 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 mine car will transport the materials required by the wet spraying machine to the concrete wet spraying machine. Workers need to hold the sprinkler head connected to the concrete wet sprayer to spray co...

Problems solved by technology

[0003] At present, before coal mines use the 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 mine car will transport the materials required by the wet spraying machine to the concrete wet spraying machine. Workers need to hold the sprinkler head connected to the concrete wet sprayer to spray concrete to the required area. Due to the poor working environment in the roadway and the high labor intensity of hand-held sprinkler heads

Taking the existing metal wall-climbing robot as an example, the adsorption methods are mainly permanent magnetic adsorption, electromagnetic adsorption and the combination of electromagnetic adsorption and permanent magnetic adsorption. It is widely used, but the adsorption force of permanent magnet adsorption cannot be adjusted, which causes the wall-climbing robot to bear a large load on the complex wall surface, resulting in large walking resistance
