[0002] Steel strand, commonly known as anchor cable, is made of multiple high-strength steel wires. It is mostly used in civil engineering or underground coal mine operations in engineering parts that have already deformed or have strict requirements on deformation. It plays a reinforcement role and requires on-site cutting and unloading.

[0003] The patent document with the publication number CN106334943A discloses an automatic unloading and bending machine for double anchor cables, including a horizontal pay-off drum, a traction device, a cutting device, a discharge device and a bending device. The horizontal pay-off drum is a double-linked horizontal pay-off drum with a horizontal axis; the traction device and the cutting device are installed on the same frame, and the cutting device is located at the rear end of the traction device and arranged close to the discharge device. The traction device is driven by a hydraulic motor, the cutting of the anchor cable is completed by an ion cutting gun, the opening of the sealing plate of the discharge device is driven by the discharge cylinder, and the length of the anchor cable to be unloaded is limited by the stroke controller. The unloading anchor cable is bent by the bending device. The beneficial effect of the above patent is that the unloading operation of two anchor cables can be performed at the same time, the production efficiency is high, the traction, cutting and unloading of the anchor cable can be completed automatically, and it can be operated by one person, and the labor intensity is low. It also has the advantages of compact structure, small equipment space occupation, high safety, simple operation and maintenance, etc., and can be used for unloading and bending operations of anchor cables.

[0004] The above-mentioned device has the following shortcomings: the above-mentioned patent cannot be used in coal mines when in use, but can only be used outside. The cut anchor cable raw material steel strands are then wound and bundled and transported to the mine. Due to the elasticity of the steel strands themselves, especially the large elastic potential energy of the wound steel strands, workers are very likely to be injured when winding and bundling on the mine and unpacking underground, which poses a safety hazard and causes significant losses; the back-and-forth transportation process is cumbersome, resulting in unnecessary waste of resources and low work efficiency; and the above-mentioned patent can only water jet cut two steel strands when in use, but cannot flexibly cut multiple steel strands by water jet according to demand.

[0017] Beneficial effects of the present invention:

[0018] (1) A cavity for holding steel strands is formed between the transmission plate and the L-shaped steel. Several groups of steel strands are placed side by side through the limit frame and extended into the cavity between the transmission plate and the L-shaped steel until the end of the steel strand touches the switch assembly. The switch assembly sends a signal to stop conveying the steel strands. The steel strands are fixed in length and cut by a water jet, so that several steel strands of equal length and fixed length are cut by the water jet. Then, the guide handle is pressed down, and the transmission plate is rotated with the hinge shaft as the rotation axis. The L-shaped steel is rotated synchronously to push out the steel strands cut by the water jet and drop them on one side of the working bracket for easy work. After the personnel take it and press down to turn the guide handle, the transmission plate rotates with the rotation of the guide handle, and at the same time, the second spring rod is gradually extended from compression, so that the push plate keeps contact with the upper surface of the lower part of the I-beam, and the sliding resistance of the push plate on the I-beam is reduced by the roller, so that the push plate stably pushes each steel strand to one side of the working bracket, and eliminates the collision and friction sparks that may be generated during pushing, avoids accidents, and improves production efficiency. At the same time, the device uses manual operation to eliminate the generation of electric sparks, so that the device can be safely used in dangerous areas such as underground coal mines;

[0019] (2) Each group of steel strands passes through the limit frame. According to the different diameters of the steel strands, the first roller moves up by different distances. At the same time, the first spring rod stretches and generates elastic force, so that the first roller and the second roller clamp each steel strand and limit the steel strand, so that the steel strands are introduced side by side without overlapping and winding. The annular groove adapts to the arcuate outer circumference of the steel strand, so that the first roller and the second roller stably clamp and stably distinguish each steel strand. When the end of the steel strand touches the toggle plate, the toggle plate rotates the sleeve, the sleeve rotates the touch block, and the touch block touches the mine explosion-proof positioning switch. The mine flameproof positioning switch sends a stop signal, and the switch assembly is quickly moved to the set length position by moving the positioning bolt, so that the steel strand can be fixed in length stably and flexibly, thereby improving production efficiency. When the end of the steel strand moves the toggle plate, the error in the fixed length of the steel strand is reduced by the thickness of the wedge-shaped piece, and the error caused by the distance between the trigger block and the mine flameproof positioning switch is eliminated, thereby improving the fixed length accuracy. The wedge-shaped piece is simple and easy to obtain, and can adapt to various environments. When the steel strand slides on the upper surface of the I-beam, the resistance of the steel strand when moving is reduced by multiple side-by-side guide rollers. BRIEF DESCRIPTION OF THE DRAWINGS
