Detailed Description

The invention is further described in detail below by means of the figures and examples. The features and advantages of the present invention will become more apparent from the description.

The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

According to the hanging net for mine restoration soil spraying provided by the invention, as shown in fig. 1, the hanging net comprises a net body 1 and a stop block 2 hung on the net body 1; the net body 1 is woven by a rope, the rope can be a metal wire such as an iron wire, or a non-metal nylon or the like, or is formed by mixed weaving of the metal wire and the non-metal wire, and can be selected according to specific construction conditions and cost budget, and the whole net body is of a soft structure, namely, can be folded into a roll, so that the net body is stored and transported in a roll shape.

When laying this string of nets, carry the net body of roll form to domatic top, roll down the net body of roll form from domatic top, if domatic comparatively smooth time, can lay its free roll down, if domatic not enough level and smooth time there is great rubble or sunken, can adjust the roll direction through auxiliary assembly such as rope and stock, so that every net body of roll can both roll down to the slope bottom smoothly, thereby the operation of spreading a net body on domatic has been accomplished, the mode of laying the net body under the package like this can improve the efficiency of construction, can also reduce the destruction of spreading the process to the net body, also greatly reduced the transportation degree of difficulty of net body.

After the baffle block 2 is mounted on the net body 1, if the net body is wound into a roll shape, the conditions of scratch and winding and the like are necessarily existed between the baffle block and the baffle block or between the baffle block and the net body, so that the net can not roll off and spread from a high place in a roll shape, and the net can only be transported and spread in other modes, thereby greatly increasing the construction difficulty. Therefore, in the application, the net body is firstly paved on the surface of the mine to be repaired, the paving process can roll from the top of the slope to the bottom of the slope in a roll shape, and the paving process is simple and convenient and has high efficiency. After the net body 1 is paved, the stop block 2 is hung on the net body 1, so that the problem that the net body is difficult to pave after carrying the stop block is avoided.

Preferably, after the rolling and laying work of the net body 1 is completed, the top of the net body 1 needs to be firmly fixed on the mine hillside by means of pin striking or the like, so that the net body 1 cannot slide downwards along with the foreign soil.

Preferably, the mesh shape on the mesh body 1 may have various shapes, such as a rectangle, a diamond, a triangle, etc., and in the present application, the mesh shape on the mesh body 1 is preferably set to be a diamond, as shown in fig. 1, the diamond mesh can improve the mounting efficiency between the mesh and the stopper, that is, the stopper 2 can be mounted on the mesh body 1 more easily.

In a preferred embodiment, as shown in fig. 2, 3 and 4, the stop block 2 is composed of at least three necessary plates, namely a retaining plate 21, a floor 22 and a mounting plate 23. Preferably, the retaining plate 21, the floor 22 and the mounting plate 23 are sequentially connected such that the overall cross section of the stopper is triangular.

The retaining plate 21 is a baffle plate which forms a preset angle with the mine surface, namely the slope where the hanging net is located after being hung on the net body 1, and the preset angle is an angle close to 90 degrees, such as 75-105 degrees; the retaining plate 21 directly contacts the soil which is sprayed on the hanging net in the follow-up process, so that the soil is supported and supported, and the soil is prevented from sliding downwards along the slope.

Preferably, a plurality of soil retaining grooves 211 are provided on the soil retaining plate 21 at a side supporting the foreign soil, thereby increasing friction between the soil retaining plate 21 and the foreign soil and further improving stability of the foreign soil.

The floor 22 is a plate which is basically parallel to the mine surface and directly attached to the net body 1 and has a fixing function after being hung on the net body 1. The bottom surface of the floor 22 is attached to the net body 1, and a hanging piece 221 and a gun 222 are further arranged on the bottom surface, and the hanging piece 221 is in a strip shape or a rod shape and is made of a metal material with certain elasticity and plasticity, such as an iron sheet and the like. Preferably, the thickness of the hanging piece 221 is 2-3mm, so that the pressure applied on the hanging piece can cause the hanging piece 221 to deform, thereby enabling the hanging piece 221 to be fastened on the string; the width of the hanging piece is smaller and controlled below 20mm, so that the hanging piece can pass through the mesh holes relatively easily.

The root of the hanging piece 221 is fixedly connected with the floor 22 in a welding way; when the stop block 2 is not hung on the net body 1, the hanging piece 221 is integrally bent, a certain gap is reserved between the top end of the hanging piece and the floor 22, and the gap can allow a rope on the net body 1 to pass through, so that when the top end of the hanging piece 221 slides on the net body 1, the top end can extend into the lower part of the rope, and the hanging piece 221 is hung on the net body 1, so that the stop block 2 is hung on the net body 1.

After the top end can extend below the thread rope, the floor 22 continues to slide along with the stop block, the hanging piece 221 and the thread rope continue to move relatively until the thread rope contacts with the root of the hanging piece 221, the thread rope and the hanging net are fixed, the hanging piece 221 deforms under the action of the stop block, the gap between the top end of the hanging piece 221 and the floor 22 becomes smaller until the hanging piece 221 is basically tightly attached to the slope or the net body 1, and the stop block stops moving under the action of the thread rope, so that the hanging operation of the stop block is completed.

Preferably, at least two hanging pieces 221 are symmetrically arranged at two ends of the floor 22, so that the stress between the floor 22 and the net body 1 is balanced; further, as shown in fig. 2, 3 and 4, the hanging pieces 221 are provided with 4 hanging pieces, that is, two rows of hanging pieces 221 are provided, the top ends of the two rows of hanging pieces 221 are different in height, and under the condition that the distance between the stop block and the net body 1 is uncertain, the possibility that the hanging pieces hang the rope can be improved through the two rows of hanging pieces 221, so that the hanging efficiency of the stop block is improved. The top height refers to the distance between the top of the hanging piece 221 and the net body or slope. Because the hanging piece 221 can be deformed due to touching stones in the process of hanging the check block on the net body, the hanging piece can not extend below the rope according to the expected situation, and the rope can be hung through the hanging piece when the hanging piece in the lower row fails by arranging the hanging pieces in the two rows, so that the hanging efficiency of the check block is further improved.

Preferably, during the process of hanging the stop, the mounting plate 23 is grasped, and the top end of the stop is controlled to move towards the direction of the net body 1 and the surface of the slope, namely to move downwards, and the downward movement is stopped when the top end approaches or abuts against the net body 1 to a certain extent; in the process of executing the downward movement, and after stopping the downward movement, the stop block moves from the high position to the low position along the inclined direction of the slope body and the net body 1, namely, the forward movement.

The top end of the stop block is the edge generated by the contact between the retaining plate 21 and the floor 22; during the downward movement, the height of the edge is substantially identical to the height of the top end of the hanging piece 21, i.e. to the distance between the net bodies 1.

Preferably, if the hanging piece 21 passes through the lower part of the rope as the stopper moves forward, the root of the hanging piece 21 will eventually contact with the rope, at this time, the rope and the net body provide tension to limit the hanging piece 21 to move forward, the mounting plate 23 and the mechanism for grabbing the mounting plate 23 slide relatively, under the action of gravity of the grabbing mechanism and the stopper, the stopper tilts towards the lower part of the slope, i.e. rotates around the top end by a certain angle, so that the floor 22 gradually contacts with the net body 1 and the slope body, the hanging piece 21 is pressed to deform and lock on the net body 1, i.e. the stopper changes from the state in fig. 3 to the state in fig. 4; while the bayonet 222 is pressed to be gradually inserted into the slope of the mine surface, into the soil or into the stone seam. When the hanging piece 21 is deformed and the floor 22 is completely attached to the net body 1, the mounting plate 23 and the mechanism for grabbing the mounting plate 23 are separated from each other, and the stop block 2 is hung on the net body 1.
