Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, specifically to a cable retractor for coal mines. Background Technology

[0002] During coal mine construction, as tunneling progresses, cables need to be wound up and unwound. However, existing cable winding and unwound racks for coal mines are inconvenient to disassemble and assemble, and it is also inconvenient to limit and fix the winding and unwound wheels after the winding and unwound operation is completed. As a result, the winding and unwound wheels can still rotate freely after the winding and unwound operation is completed, which affects the effect of cable winding and unwound. In addition, after the cable winding and unwinding operation is completed, the wound cable may become loose. In order to solve the above problems, the inventor proposed a cable winding and unwound rack for coal mines. Utility Model Content

[0003] The purpose of this utility model is to provide a cable retractor for coal mines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cable winding and unwinding rack for coal mines, comprising a fixed plate, on which a winding and unwinding wheel is rotatably mounted, and a cable is wound on the winding and unwinding wheel. The fixed plate is equipped with a force-reverse constraint component that causes the winding and unwinding wheel to rotate under the tension of the cable, for limiting the movement of the winding and unwinding wheel.

[0005] Preferably, the two sides of the take-up and take-down wheels are provided with a plurality of symmetrically arranged slots.

[0006] Preferably, the reverse constraint assembly includes a connecting block and a connecting rod. A tension band is installed on the connecting block, and a hook is installed at the end of the tension band. The connecting rod is inserted into a slot to limit the winding end or the take-up and unwinding end of the cable. The hook is hooked onto the connecting rod, and the rotation of the take-up and unwinding wheel is limited by the constraint of the tension band.

[0007] Preferably, the upper and lower sides of the fixing plate are equipped with slide rails located on both sides of the take-up and take-down wheels. The connecting block is slidably disposed on the slide rail. The middle part of the slide rail protrudes outward to form an arc-shaped slide rail. The connection end between the connecting block and the slide rail is provided with a locking block that protrudes outward and locks into the outward protruding part.

[0008] Preferably, the two ends of the connecting rod are provided with limiting blocks that match the slots to limit the rotation of the connecting rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the reverse constraint component, after the take-up or release wheel takes up or releases the cable, the connecting rod is inserted into the slot and hooked on the connecting rod by the reverse constraint component, which suppresses the rotation of the take-up or release wheel in the direction of cable rotation, thereby limiting the cable. In addition, the connecting rod can limit the take-up or release end or the winding end of the cable, which can prevent the cable wound on the take-up or release wheel from becoming loose.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 This utility model provides a technical solution: a cable winding and unwinding rack for coal mines, including a fixed plate 1, on which a winding and unwinding wheel 2 is rotatably mounted, and a cable is wound on the winding and unwinding wheel 2. The fixed plate 1 is equipped with a reverse constraint component 3 that limits the rotation of the winding and unwinding wheel 2 under the pulling force of the cable.

[0015] The two sides of the take-up and take-down wheel 2 are provided with multiple symmetrically arranged slots 4.

[0016] The reverse constraint assembly 3 includes a connecting block 31 and a connecting rod 32. A tension band 33 is installed on the connecting block 31, and a hook 34 is installed at the end of the tension band 33. The connecting rod 32 is inserted into the slot 4 to limit the winding end or the take-up end of the cable. The hook 34 is hooked on the connecting rod 32, and the rotation of the take-up wheel 2 is limited by the constraint of the tension band 33.

[0017] The upper and lower sides of the fixed plate 1 are equipped with slide rails 5, which are located on both sides of the take-up and release wheels 2. The connecting block 31 is slidably disposed on the slide rail 5. The middle part of the slide rail 5 protrudes outward to form an arc-shaped slide rail. The connecting end of the connecting block 31 and the slide rail 5 is provided with a locking block 6 that protrudes outward and locks into the protruding part.

[0018] The connecting rod 32 is provided with limiting blocks 7 at both ends that match the slot 4, which are used to limit the rotation of the connecting rod 32.

[0019] Working principle: When using this utility model, the connecting block 31 is positioned in different positions on the slide rail 5 according to the cable winding or unwinding of the take-up and unwinding wheel 2. When the cable winding or unwinding of the take-up and unwinding wheel 2 is finished and it needs to be limited, the connecting rod 3 is inserted into the slot 4 corresponding to the part of the cable on the take-up and unwinding wheel 2, then the connecting block 31 is locked in the slide rail 5, the hook 34 is hooked on the connecting rod 32, and then the force acting on the take-up and unwinding wheel 2 is released. The take-up and unwinding wheel 2 will rotate under the pull of the cable. The rotation of the take-up and unwinding wheel 2 is suppressed by the tension band 33, thus completing the limitation of the cable winding or unwinding.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
