Full-automatic sprayed concrete conveying and unloading equipment and concrete conveying and unloading method

Abstract

The invention provides full-automatic sprayed concrete conveying and unloading equipment. The equipment comprises a hopper with an upper opening, a concrete conveying device and a concrete spraying device which are sequentially arranged; an inner cavity of the hopper is used for holding sprayed concrete, and a discharging opening is formed in the bottom of the hopper; the concrete conveying deviceis provided with a feeding end and a discharging end, wherein the feeding end is used for being connected and fixed to the discharging opening of the hopper; the concrete spraying device comprises aconveying trolley with an inclined upper surface and two concrete spraying machines with feeding openings, wherein the two concrete spraying machines are fixed on the upper surface of the conveying trolley and used for spraying the concrete; and when in use, the discharging end of the concrete conveying device corresponds to the feeding opening positions of the two concrete spraying machines, andthe sprayed concrete can reach the concrete conveying device from the hopper through the discharging opening, and is conveyed to the two concrete spraying machines through the concrete conveying device to be subjected to concrete spraying. The invention also provides a concrete conveying and unloading method.

Description

technical field [0001] The invention relates to the technical field of shallow-buried tunnels or tunnels for large-slope rail transportation, and in particular to a fully automatic shotcrete transporting and unloading device and a concrete transporting and unloading method. Background technique [0002] In the process of tunnel excavation and support, it is often encountered that large-slope inclined shafts need to carry out the transportation and spraying construction of shotcrete. The mine bucket truck is used as a rail transportation tool. After the shotcrete is transported to the working face, excavators and manual Cooperate with unloading the shotcrete to the ground; when spraying anchors, multiple workers are required to shovel the shotcrete unloaded on the ground into the concrete spraying machine. This method has many disadvantages and requires many workers to unload and load materials. The cooperation of excavators is also required, and the sprayed concrete scattere...

[0002] In the process of tunnel excavation and support, it is often encountered that large-slope inclined shafts need to carry out the transportation and spraying construction of shotcrete. The mine bucket truck is used as the rail transportation tool. After the shotcrete is transported to the working face, excavators and manual Cooperate with unloading the shotcrete to the ground; when spraying anchors, multiple workers are required to shovel the shotcrete unloaded on the ground into the concrete spraying machine. This method has many disadvantages and requires many workers to unload and load materials. The cooperation of excavators is also required, and the sprayed concrete scattered on the ground cannot be used after contact with soil and other sundries. The machine needs to be placed fixedly, and the ground where the concrete sprayer is placed needs to be leveled, which will damage the bottom plate of the inclined shaft to a certain extent, and using an excavator to level the site and placing the concrete sprayer will waste a lot of time
