Description

Technical Field

[0001] The present invention relates to a metal mesh device for coal mines, and specifically to a portable connecting metal mesh device for coal mines. Background Art

[0002] In the support of coal mine roadways, the metal mesh support has a usage rate of over 90% in coal mines, and the support effect is good, which can greatly reduce the deformation of roadways. However, the connection of metal mesh sheets is rather troublesome and time-consuming. Therefore, developing a device for automatically bundling iron wires can improve the connection efficiency of metal meshes, which has important practical significance for on-site construction. Currently, many coal mines still use manual hooks and binding wires to bundle and connect metal meshes. This method is laborious and time-consuming, with a high labor cost and low efficiency. There is also a device used for binding building steel bars on the market, which has high efficiency, but its structure is complex and the cost is high, and it is not suitable for the humid and dusty working conditions underground in mines. Summary of the Invention

[0003] In order to overcome the problems existing in the connection of diamond-shaped metal meshes in current coal mine shafts, the present invention provides a portable automatic connecting anchor mesh device for coal mines. This device is small in size, convenient to operate, high in efficiency, capable of continuous bundling, relatively simple in structure, suitable for the complex working conditions of humidity and large dust underground in mines, and has a relatively low manufacturing cost.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A portable connecting metal mesh device for coal mines is composed of a control grip, a battery, a transmission shaft, a rotating motor, a chassis, an axle box, a folding dust cover, an adjusting nut, an adjusting rod, a wire box, a wire, a right arm, a left arm, an adjusting spring, a control knife grip, a control wire grip, and a retractable knife. Among them, the right arm and the left arm cooperate to wind the wire around the object to be connected. The control grip controls the rotating motor to drive the right arm and the left arm to rotate, so as to tighten and cut the wire. The rotating shaft parts at the bottoms of the right arm and the left arm are connected to the axle box through a rotating shaft. There is a folding dust cover at the connection part of the right arm, the left arm and the axle box. There are fixing rings on the right arm and the left arm to limit the position of the wire.

[0009] Further, when the wire is placed in the wire box, there is a circular ring at the tail of the wire, which is fixed in the wire box. The other end of the wire extends out from the left hole of the wire box, passes through the limiting holes of the left arm and the right arm, and enters through the right hole of the wire box. Finally, the head is fixed on the fixing rod in the wire box.

[0010] Further, the distance adjusting rod is fixed in the opening at the connection between the wire box and the axle box, and at the same time passes through the adjusting holes of the right arm and the left arm. There is a distance adjusting nut on the distance adjusting rod to adjust the maximum opening size of the right arm and the left arm.

[0011] Further, the knife control grip is connected to the right arm. There is a button on the knife control grip. When the button is pressed, the retractable knife retracts into the knife storage groove. When the button is released, the retractable knife pops out.

[0012] Further, the wire control grip is connected to the left arm. There is a button on the wire control grip. When the button is pressed, the wire is free. When the button is released, the wire is clamped by the wire control grip.

[0013] Further, the left and right ends of the adjusting spring are fixed on the wire control grip and the knife control grip. The adjusting spring can make the distance between the right arm and the left arm maximum in the state of not applying force, and make the distance between the right arm and the left arm minimum when the hand is tightly held.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: small volume, light weight, convenient operation, high efficiency, capable of continuous bundling, relatively simple structure, suitable for complex working conditions such as damp and dusty underground mines, and low manufacturing cost.
