Abstract
Description
Technical Field
[0001] The utility model relates to a cutting and unloading system for supporting anchor cables in underground coal mine tunnels. Background Art
[0002] In underground coal mine tunnel support operations, anchor cables, a key support material, are in high demand. These cables are typically purchased in coils and cut to the appropriate diameter and length based on the specific support requirements.
[0003] In the prior art, the anchor cable is cut by loading the rolled anchor cable onto the anchor cable unwinding wheel and then cutting it with an anchor cable cutter. During cutting, multiple workers are usually required to cooperate in laboriously pulling out the anchor cable of the required length from the anchor cable unwinding wheel for cutting. After the cutting is completed, two people are required to place the anchor cable on one side of the anchor cable cutter, which not only leads to high labor intensity for the workers, but also low production efficiency. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a cutting and unloading system for supporting anchor cables in underground coal mine tunnels, which has relatively low labor intensity when cutting anchor cables and relatively high production efficiency.
[0005] In order to solve the above technical problems, the utility model is used for the cutting and unloading system of anchor cables for supporting underground tunnels in coal mines, including anchor cable unwinding discs and anchor cable cutting machines arranged at the front and rear, and also including a long strip mounting platform. A straightening wire feeding machine is also arranged between the anchor cable unwinding disc and the anchor cable cutting machine, and an anchor cable flipping and blanking device is also arranged on the rear side of the anchor cable cutting machine. The anchor cable cutting machine, straightening wire feeding machine and anchor cable flipping and blanking device are all fixed on the mounting platform, and the anchor cable flipping and blanking device is used to unload the cut anchor cable to one side of the mounting platform.
[0006] As an improvement of the present invention, the anchor cable flipping and blanking device includes a long strip of angle iron arranged along the length direction of the mounting platform, and angle iron mounting columns and slide rod mounting columns are fixed at intervals along the length direction on the mounting platform below the angle iron. The upper part of the angle iron mounting column is rotatably provided with a flap through a first rotating shaft, and a V-shaped groove corresponding to the angle iron is formed on the top of the flap. The angle iron is fixed in the V-shaped groove at the top of the flap, and the lower part of the flap is provided with a second rotating shaft perpendicular to the flap, and the second rotating shaft is connected to the piston rod of the oil cylinder hinged on the mounting platform, and the extension and retraction of the oil cylinder piston rod can drive the flipping action of the flap; the top of the slide rod mounting column is located below the angle iron, and the upper part of each slide rod mounting column is connected with a slide rod that extends obliquely downward to the outside of the mounting platform.
[0007] When the utility model is in use, the anchor cable on the anchor cable unwinding disc becomes straight after passing through the straightening wire feeding machine, and the straight anchor cable can be extended into the long strip angle iron in the anchor cable flipping and blanking device after passing through the anchor cable cutting machine. The oil cylinder is controlled, and the extension of the oil cylinder piston rod can drive the flipping of the flap so that the supporting anchor cable cut into a specified length by the anchor cable cutting machine slides out from the long strip angle iron, and falls to one side of the installation platform through the guidance of the sliding rod. The oil cylinder is controlled again, and the retraction of the oil cylinder piston rod can drive the reverse flipping of the flap, and the long strip angle iron is reset, so that the next anchor cable cutting action can be performed.
[0008] The utility model has the following beneficial technical effects: First, in the utility model, the straightening wire feeding machine is mainly used to feed the anchor cable during cutting, and the labor intensity of the workers is relatively low; second, an anchor cable flipping and blanking device is provided in the utility model, and the support anchor cable after cutting can automatically slide to one side, further reducing the labor intensity of the workers; third, after the straightening wire feeding machine is adopted in the utility model, the wire feeding speed of the anchor cable is faster, and after adopting the anchor cable flipping and blanking device, there is no need to manually transport the support anchor cable to the designated location, thereby improving production efficiency.
