[0017] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0018] like Figure 1 As shown: a portable coal mine anchor mesh spraying roadway small wire hanging device, including a steel mesh 1, a tightening screw 2 and a wire harness connector; the steel mesh 1 is fixed on the roadway wall by the tightening screw 2, and the steel mesh 1 is parallel to the roadway roof and the roadway floor; the steel mesh 1 is a hard mesh that can remain parallel to the roadway wall and has high flatness; the wire harness connector is installed on the steel mesh 1 along the direction of the small wire 3 in the roadway, and the small wire is supported and positioned by the wire harness connector.
[0019] The wire harness connectors on the steel mesh 1 are horizontally distributed and parallel to the tunnel roof and tunnel floor, and are arranged vertically according to the number of small wires; the wire harness connectors include small hooks 4 and cable clamps 5, which are arranged alternately in sequence horizontally. The small hooks 4 only support the small wires to prevent them from bending down. The cable clamps 5 can not only support the small wires, but also limit their sliding back and forth and jumping up and down. Compared with using only cable clamps 5, the cost of using the small hooks 4 and cable clamps 5 together is lower.
[0020] The steel mesh 1 is a warp and weft mesh with a specification of 50mm×50mm. A harness connector is installed every 3-5 small grids on the steel mesh 1. The steel mesh 1 is a rectangular mesh with a length of 2m and a width of 1m. The steel mesh 1 is fixed to the side of the lane by tightening screws 2 at the four corners. The tightening screws 2 can effectively act on the side of the anchor mesh spraying lane to fix the steel mesh 1. It is easy to install and disassemble and easy to operate.
[0021] The harness connectors on the steel mesh 1 are distributed in a rectangular array, with the small hooks 4 in the same row and the cable clips 5 in the same row, ensuring neat hanging and standardized dynamic compliance.
[0022] The small hook 4 is a semicircular arc, and one end of the small hook 4 is vertically welded to the steel mesh 1.
[0023] like Figure 2 As shown: one of the pressing handles of the cable clamp 5 is vertically welded to the steel mesh 1, and the inner edge of the wire clamping part of the cable clamp 5 is inlaid with an insulating skin 5.1; the insulating skin 5.1 can increase the friction force, clamp the small wire tightly and prevent it from falling; and protect the small wire while clamping it.
[0024] The small wires 3 include telephone wires, emergency broadcast wires, gas monitoring wires, positioning system transmission wires, various sensor transmission wires and online monitoring wires. The various small wires are hung one by one on the small hooks 4 and cable clamps 5 of the steel mesh 1. The same small wire is fixed on the small hooks 4 and cable clamps 5 on the same horizontal line. The cable clamps 5 clamp the small wires to ensure that the hanging is neat and the standardized dynamic standard is met.
[0025] The portable coal mine anchor net spraying laneway small wire hanging device is simple to install, labor-saving, safe, efficient, and easy to operate; any small wire can be independently disassembled and hung, while other small wires are not affected. Save costs and effectively reduce material loss. (Take the 1200-meter main belt lane of a mine as an example, a lifting anchor rod is injected every 3 meters, and a total of 400 anchor rods are required. Each anchor rod costs 55 yuan, and each cable hook costs 5 yuan, a total of 24,000 yuan is required; using the portable coal mine anchor net spraying laneway small wire hanging device of this embodiment, the steel mesh 1 needs to be 1200m*1m, and the processing fee is 10 yuan per square meter of steel mesh 1; each steel mesh 1 (mesh specification length × width = 2m×1m) is fixed with 4 tightening screws 2, each tightening screw costs 1 yuan, including small hooks 4 and cable clips 5, all costs total about 14,000 yuan, directly saving costs of 10,000 yuan).
