Description

Technical Field

[0001] This utility model belongs to the field of cable winding technology, specifically a coal mine cable winding support device. Background Technology

[0002] In the coal mine safety production system, cables serve as the core carrier of underground power supply, communication, and monitoring systems. Their reliability directly affects the normal operation of critical aspects such as mine ventilation, drainage, and gas monitoring. Due to the complex underground working conditions, cables require frequent maintenance, replacement, and coiling for storage. Traditional manual winding operations have three major drawbacks: low efficiency, as heavy cables rely on multiple people to drag and coil them, resulting in high labor intensity and a single operation taking several hours; high safety risks, as manual operation easily leads to muscle strains or hand cuts (metal fragments often adhere to the cable surface), with industry statistics in the past three years showing that such accidents account for 17%; and lack of standardization, as manual coiling leads to uncontrolled cable bending radii, interlayer cross-winding, accelerated insulation aging, and potential hazards such as leakage and short circuits.

[0003] To overcome the aforementioned bottlenecks, the industry has gradually promoted motor-driven cable winding and support devices, which achieve mechanized cable winding and unwinding through gearbox transmission and rigid support frame coordination. While this device improves operational efficiency and safety, it has also exposed a key technical flaw: The existing equipment uses a fixed support structure, which can only accommodate cable winding racks of a single specification (usually large racks with a standard diameter ≥1.5m). However, there are a large number of medium and small winding racks with diameters of 0.8-1.2m in coal mines. The support width and shaft hole size of these racks differ significantly from those of the large racks, making it impossible to install the equipment effectively. When the spacing between the support racks is too wide, it causes swaying due to suspension. There are also issues with the shaft length supporting the rotation of the cable winding rack being insufficient, or extending the shaft length affecting the winding stability of the rack and causing swaying. If separate support devices are configured for winding racks of different specifications, it will not only increase equipment procurement costs but also lead to redundant underground spare parts storage and a sharp increase in maintenance complexity, seriously hindering intensive production management. Utility Model Content

[0004] To address the issues of high procurement costs, large storage space requirements, and increased subsequent maintenance costs associated with configuring multiple support devices for cable winding racks of different specifications, this utility model provides a coal mine cable winding support device.

[0005] This utility model is achieved through the following technical solution: A coal mine cable winding support device includes a support frame, which includes a base frame formed by two short side beams and two long side beams. Side support frames are provided on the short side beams, and an auxiliary support frame detachably mounted on the base frame is provided between the two side support frames. The top of the side support frames and the auxiliary support frames are provided with a support seat. Two bearings are rotatably provided on the support seat, which are spaced apart and can be used to support the rotation of the cable winding frame. The center lines of the two bearings are parallel in the horizontal plane.

[0006] The two side support frames can provide adaptive support for the largest cable winding racks. By temporarily assembling an auxiliary support frame between the two side support frames and adjusting the distance between the auxiliary support frame and one of the side support frames according to the specific cable winding rack specifications, the compatibility problem for cable winding racks of different specifications is solved, significantly enhancing the versatility of parts, reducing storage space pressure, and saving subsequent maintenance costs.

[0007] A further improvement of this utility model is that the aforementioned auxiliary support frame includes an auxiliary support beam and two auxiliary support beams. The auxiliary support beam is connected to the bottom surface of the support base, and the two auxiliary support beams are respectively connected to the two ends of the auxiliary support beam. An auxiliary snap-fit ​​component is connected to the end of the auxiliary support beam away from the auxiliary support beam. The cross-section of the auxiliary snap-fit ​​component is generally U-shaped, and the auxiliary snap-fit ​​component can snap onto the long side beam. By adapting the U-shaped auxiliary snap-fit ​​component to the long side beam, the installation of the auxiliary support frame on the bottom frame is completed. At the same time, the two bearings at the top of the auxiliary support frame provide support for one end of the support shaft of the cable winding frame. Under the weight of the cable winding frame itself, a three-point support is formed with the two auxiliary snap-fit ​​components, stabilizing the assembly and use of the auxiliary support frame on the bottom frame.

[0008] A further improvement of this invention is that a locking component is provided between the auxiliary support beam and one of the side support frames. This locking component reinforces the connection between the auxiliary support beam and the side support frame, enhancing the stability of the auxiliary support frame on the base frame.

[0009] A further improvement of this invention is that an auxiliary reinforcing rib is connected between the two auxiliary connectors. This auxiliary reinforcing rib enhances the structural strength of the entire auxiliary support frame.

[0010] A further improvement of this invention is that a locking component two is connected between the aforementioned auxiliary reinforcing rib two and one of the short side beams. The locking component two and the locking component one form an upper and lower connection, optimizing the overall stability and strength.

[0011] A further improvement of this invention is that an auxiliary reinforcing rib is connected between the two auxiliary support beams, which can enhance the structural strength of the middle part of the auxiliary support frame.

[0012] A further improvement of this utility model is that the aforementioned side support frame includes a side support beam and two side support beams, the two ends of which are respectively connected to the two ends of the short side beam through the side support beams; the side support beam can be connected to the locking assembly.

[0013] A further improvement of this utility model is that the locking assembly includes a locking screw and locking nuts. The two ends of the locking screw can pass through the auxiliary support beam and the side support beam, respectively. Four locking nuts are provided, two of which are threaded onto the locking screw and clamp the auxiliary support beam, while the other two are threaded onto the locking screw and clamp the side support beam. The clamping of one of the support beams is achieved through the cooperation of two locking nuts and the locking screw, making operation convenient.

[0014] A further improvement of this invention is that the structure of the second locking component is the same as that of the first locking component. The identical structure of the second locking component and the first locking component results in the same operation method, improving overall operational convenience.

[0015] A further improvement of this utility model is that the cross-section of the aforementioned support seat is generally U-shaped, and the upper part of the side walls of the support seat is provided with support grooves, which can support the second support shaft passing through the bearing. The support grooves realize the accommodation of the second support shaft supporting the bearing, which is convenient to use.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are: the two side support frames can form adaptive support for the largest specification cable winding rack. By temporarily assembling an auxiliary support frame between the two side support frames and adjusting the distance between the auxiliary support frame and one of the side support frames according to the specific cable winding rack specifications, the adaptation problem for cable winding racks of different specifications is solved, significantly enhancing the versatility of parts, reducing storage space pressure and saving subsequent maintenance costs.

At the same time, the two bearings 61 at the top of the auxiliary support frame 13 provide support for one end of the support shaft 21 of the cable winding frame 20. Under the weight of the cable winding frame 20, a three-point support is formed with the two auxiliary snap-fit ​​components 135, stabilizing the assembly and use of the auxiliary support frame 13 on the bottom frame 11.
