Description

Technical Field

[0001] This utility model relates to the field of coal mining machinery, specifically to a mining rubber-wheeled cable car. Background Technology

[0002] Due to the long lengths of cables laid and retrieved in underground roadways, cable laying is primarily done by first using explosion-proof engineering vehicles to pull the cables to the vicinity of the work site, where workers manually pull the cables from the cable reels and unroll them into the roadway. Cable retrieval is done manually, pulling the cables to the loading point, loading the cable reels into the truck, and transporting them to the surface. Because of the large cross-section and heavy weight of the cables, multiple workers are required simultaneously. This manual labor is inefficient, physically demanding, and poses significant safety hazards. Furthermore, as the working face advances underground, the cable length gradually becomes excessive. Once a certain distance is reached, the cable between two junction boxes, typically 500 meters long, is removed. This is usually done manually, coiled together, and then pulled to the surface by mining vehicles. Because the cables are heavy, manually coiling and pulling them is time-consuming and labor-intensive, resulting in low efficiency. The coiled cables then need to be hoisted using chain hoists and other lifting equipment before being pulled to the surface, making the process cumbersome.

[0003] Utility model patent CN218708072U discloses an automatic cable reel for coal mine roadways, comprising a vehicle body, a power unit, and a cable reel. The vehicle body includes a frame, with a first base plate and a second base plate fixedly installed at its left and right ends, respectively. The advantages are that by using a tracked system, the cable reel moves forward with the advancing working face, and a hydraulic motor drives the cable reel, reducing worker fatigue and ensuring rapid working face advancement. When the power supply equipment for the working face is placed on an equipment train, the cable reel is positioned on the high-voltage side at the front of the train, automatically reeling up the high-voltage cable as the train moves forward. When long-distance power supply is used, the cable reel is positioned in the roadway 30m to 50m from the working face. Multiple cable reels can be deployed depending on the number of cables. As the working face advances, the cable reel moves forward and reels up any excess cable, maintaining a constant distance between the working face and the cable reel, thus improving work efficiency. However, the structure disclosed for the automatic cable reel used in coal mine roadways does not have the function of lifting high-voltage cable reels, making loading and unloading operations inconvenient. Utility Model Content

[0004] To increase the convenience of cable winding and unwinding in coal mines and to facilitate the loading and unloading of cable coils onto transport vehicles, the technical solution adopted by this utility model is: a mining rubber-tired cable reel vehicle, including a walking mechanism, a cable support arm assembly, a drive motor, and a cable guide frame assembly.

[0005] The cable support arm assembly can be lifted and lowered at one end of the traveling mechanism to support and lift the cable reel;

[0006] The drive motor is mounted on the cable support arm assembly. A drum shaft is detachably connected to the drive motor's transmission shaft. The drum shaft passes through the cable reel. The drive motor is used to drive the drum shaft to rotate, thereby causing the cable reel to rotate.

[0007] The cable guide frame assembly is oscillatingly mounted on the cable support arm assembly to guide the cable on the cable reel.

[0008] Based on the above, one end of the walking mechanism is provided with an outer frame, and an inner lifting frame is slidably arranged inside the outer frame. The cable support arm assembly is connected to the inner lifting frame.

[0009] A lifting cylinder is provided between the inner lifting frame and the outer frame. The lifting cylinder is used to push the inner lifting frame to slide within the outer frame, thereby driving the cable support arm assembly to rise and fall.

[0010] Based on the above, the inner lifting frame is also provided with rollers that roll in cooperation with the outer frame. The rollers are used to guide the inner lifting frame when it slides inside the outer frame.

[0011] Beneficial effects: Due to the significant weight of the cable reel after collecting the cable, there is considerable lateral pressure between the inner lifting frame and the outer frame during the lifting process. By installing rollers on the inner lifting frame that roll in conjunction with the outer frame, and using these rollers for guidance, friction is reduced, and relative movement between the inner lifting frame and the outer frame is facilitated.

[0012] Based on the above, the cable support arm assembly includes a side U-shaped support arm and a pair of roller supports disposed on the side U-shaped support arm. Each roller support is provided with an anti-detachment plate, and the roller supports are used to provide rolling support for the drum shaft.

[0013] The drive motor is positioned directly opposite one of the roller support shafts, and the side U-shaped support arm is fixedly connected to the inner lifting frame.

[0014] Beneficial effect: By setting a pair of roller supports on the cable support arm assembly and setting anti-detachment plates on the roller supports respectively, the roller supports can be used to provide rolling support for the drum shaft.

[0015] Based on the above, the cable guide frame assembly includes a cable guide frame rotary cylinder, a pair of cable guide arms, a lead screw drive motor, a lead screw, and a cable guide frame;

[0016] The cable guide arms are respectively hinged to the outer ends of the side U-shaped support arms. The cable guide frame rotating cylinder is installed on the side U-shaped support arm and is in transmission cooperation with one of the cable guide arms. The cable guide frame rotating cylinder is used to drive the cable guide arm to swing.

[0017] The lead screw is connected between a pair of cable guide arms, the cable guide frame is slidably disposed on the lead screw, and the lead screw drive motor is mounted on the cable guide arm and is driven by the lead screw.

[0018] The lead screw drive motor is used to drive the lead screw to rotate, thereby causing the cable guide frame to move on the lead screw.

[0019] Based on the above, a groove is provided at one end of the drum shaft, and a square shaft head that can be detachably inserted into the groove is provided on the drive shaft of the drive motor.

[0020] Based on the above, the walking mechanism is a rubber-wheeled vehicle, and the rubber-wheeled vehicle is provided with support legs around its perimeter, which are used to support the rubber-wheeled vehicle.

[0021] Beneficial effects: When working, the support legs can be used to support the rubber-wheeled vehicle, thereby improving operational stability.

[0022] Based on the above, the roller support shaft includes a U-shaped structural component and a roller that is rolled inside the U-shaped structural component. The opening of the U-shaped structural component is oriented towards the cable guide frame assembly. The anti-detachment plate is detachably installed on the opening of the U-shaped structural component, and the roller is disposed inside the anti-detachment plate.

[0023] Beneficial effects: Since the opening of the U-shaped structure is set towards the cable tray assembly, the U-shaped structure can be engaged with both ends of the drum shaft by the movement of the traveling mechanism, thereby completing the action of supporting and lifting the cable drum.

[0024] Based on the above, a frame connecting plate for connecting the walking mechanism is provided on the inner side of the outer frame.

[0025] This utility model has substantial features and advancements compared to existing technologies. Specifically, the mining rubber-tired cable reel trolley provided by this utility model features a cable support arm assembly that can be lifted and lowered at one end of the traveling mechanism. This cable support arm assembly supports and lifts the cable reel, while a drive motor is installed on the cable support arm assembly. A reel shaft is detachably connected to the drive motor's transmission shaft, allowing the drive motor to rotate the reel shaft and thus rotate the cable reel. This achieves powered cable winding and unwinding, improving the efficiency and convenience of cable winding and unwinding. Furthermore, the lifting function of the cable support arm assembly itself allows the cable reel and cable to be loaded and unloaded together onto a transport vehicle, thus avoiding the need for crane lifting.

[0026] Furthermore, by installing a cable guide frame assembly on the outside of the cable support arm assembly, the cable can be guided during cable winding and unwinding, thereby improving the neatness and stability of the cable winding and unwinding process.

[0027] Therefore, this mining rubber-wheeled cable reel increases the convenience of cable winding and unwinding in coal mines, and also makes it easier to load and unload cable coils onto transport vehicles. Attached Figure Description
