Description

Technical Field

[0001] This utility model relates to cable winding equipment technology, specifically to an automatic winding and hanging device for mining cables. Background Technology

[0002] Currently, in underground mine roadways, cable laying and retrieval largely rely on manual dragging or fixed mechanical retrieval devices. The underground working environment is extremely complex: roadways are narrow, ceiling heights vary, and the ground is often uneven, scattered with sharp debris such as gangue, coal slag, and metal shavings; simultaneously, the air has high dust concentrations, high humidity, and the presence of explosive gases, among other special safety requirements. Under these harsh conditions, if cables are laid directly on the ground, they are prone to continuous friction, compression, and even cutting with the surface, leading to severe wear on the cable sheath and insulation layer. This not only shortens the cable's lifespan but may also cause safety hazards such as short circuits, leakage, and electric arcs, and in severe cases, lead to electromechanical accidents or mine fires, posing a significant threat to personnel and equipment.

[0003] Based on this, the present invention provides an automatic cable retraction and suspension device for mining. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an automatic cable reeling and suspension device for mining. The reel's height can be precisely adjusted (e.g., to avoid ground obstacles and match the height of the tunnel roof), enabling the cable to be suspended in the air, thus avoiding the wear and tear caused by traditional ground-dragging cable laying. Compared to manually fixed-height devices, this reduces the risk of insulation damage caused by friction and compression. Suspended cable laying also prevents direct contact between the cable and ground debris or coal slag, reducing surface scratches and insulation aging from the outset.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cable reeling and suspension device for mining, comprising a movable base; a lifting component disposed on the top of the movable base; a take-up reel disposed on the lifting component via a frame; a first driving component disposed within the frame for driving the take-up reel to rotate within the frame; wherein, the lifting component comprises multiple telescopic components, all disposed on the top of the movable base, and the frame is disposed between the top ends of each telescopic component; a second driving component disposed on the top of the movable base for driving the frame to move up and down.

[0006] Furthermore, it also includes a cleaning mechanism mounted on the frame for cleaning dust and impurities from the outer surface of the cable.

[0007] Furthermore, the cleaning mechanism includes a lever arm disposed on the frame; a guide frame disposed on the side end of the lever arm; and two sets of cleaning rollers disposed sequentially on both sides of the guide frame.

[0008] Furthermore, the cleaning mechanism also includes a slide rod slidably disposed on the side of the guide frame; a pressure plate is disposed at the top of the slide rod; a pull bar is disposed at the bottom of the slide rod; a spring is disposed in the middle of the slide rod between the pressure plate and the guide frame; a pair of limiting bars are disposed on the side of the guide frame, and the pull bar can rotate to contact the two limiting bars, so that the pressure plate is separated from the cable.

[0009] Furthermore, the drive component is connected to the take-up reel via a transmission belt.

[0010] Furthermore, the movable base includes a base plate and rollers disposed at the bottom of the base plate.

[0011] Compared with the prior art, the present invention provides an automatic cable winding and unwinding suspension device for mining cables. The cable is wound around a take-up reel, and the take-up reel is driven to rotate by a drive component one to complete the winding or unwinding of the cable. Considering the special environment inside the mine, the frame can be moved up and down by a drive component two, so that the position of the take-up reel can be adjusted up and down, thereby completing the arrangement of the cable position height and the suspension of the cable (avoiding the cable dragging on the ground).

[0012] This structural design allows for precise height adjustment of the cable reel via a lifting mechanism (e.g., to avoid ground obstacles and match the height of the tunnel roof), enabling overhead cable laying and avoiding the wear and tear caused by traditional ground-dragging cable installation. Compared to manually fixed height devices, this reduces the risk of insulation damage caused by friction and compression. The suspended cable installation also prevents direct contact between the cable and ground debris or slag, minimizing surface scratches and insulation aging from the outset.

[0013] During cable winding or unwinding, the outer surface of the cable can contact each cleaning roller, allowing the cleaning roller to clean dust and impurities from the outer surface of the cable. After the cable pull-out position is determined, the pull bar can be rotated to offset the pull bar from the two limiting bars. Then, the spring extends, causing the side of the pressure plate to press against the side of the cable to fix the cable. At the same time, this prevents the cable end from dragging on the ground when winding the cable. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] Example 1:

[0024] This utility model provides an automatic cable winding and unwinding suspension device for mining, including a movable base 1, a lifting component 2, a take-up reel 3, and a drive component 6. The lifting component 2 is located on top of the movable base 1. The take-up reel 3 is mounted on the lifting component 2 via a frame 4. The drive component 6 is located inside the frame 4 and is used to drive the take-up reel 3 to rotate within the frame 4. The movable base 1 includes a base plate and rollers located at the bottom of the base plate. The base plate is welded from high-strength steel plate (such as Q345B) and has sufficient rigidity and deformation resistance to bear the weight of the take-up reel 3 and the lifting component 2 after the cable is fully wound. A counterweight mounting position can be provided on the base plate to increase the counterweight as needed and improve the stability of the whole machine. Two of the four rollers have a braking function to ensure that the device can be parked stably on slopes. A battery compartment is integrated into the base plate to achieve electric movement.

[0025] The lifting component 2 includes multiple telescopic components 200 and a second driving component 201; the multiple telescopic components 200 are all located on the top of the movable base 1, and the frame 4 is located between the top ends of each telescopic component 200; the second driving component 201 is located on the top of the movable base 1 and is used to drive the frame 4 to move up and down.

[0026] Specifically, drive component 6 is a motor, model LYJ160-60 / 4; drive component 201 is an electric cylinder (or a screw drive structure, using a double scissor fork lifting mechanism or a multi-stage hydraulic cylinder / electric cylinder), model FXK I 190; and telescopic component 200 is equidistantly arranged on the movable base 1 and is a telescopic rod component.

[0027] Specifically, the cable is wound around the take-up reel 3, and the take-up reel 3 is driven to rotate by the drive component 6 to complete the winding or unwinding of the cable. Considering the special environment inside the mine, the frame 4 can be moved up and down by the drive component 201, so that the position of the take-up reel 3 can be adjusted up and down, thereby completing the arrangement of the cable position and height and the suspension of the cable (to avoid the cable dragging on the ground).

[0028] Through this structural design, the height of the cable can be precisely adjusted via the lifting component 2 and the take-up reel 3 (e.g., to avoid ground obstacles and match the height of the tunnel roof), enabling the cable to be suspended in the air and avoiding the wear and tear caused by traditional ground-dragging cable laying. Compared with manually fixed height devices, this reduces the risk of insulation damage caused by cable friction and compression. Suspended cable laying also avoids direct contact between the cable and ground gravel and cinders, reducing surface scratches and insulation aging from the source.

[0029] Example 2:

[0030] This embodiment is a further optimization based on the above embodiment one. The parts that are the same as the aforementioned technical solutions will not be repeated here. In order to better realize this utility model, the following setting method is adopted. In this embodiment, an automatic cable retraction and suspension device for mining also includes a cleaning mechanism 5 set on the frame 4 for cleaning dust and impurities on the outer side of the cable.

[0031] like Figure 3 and Figure 4 As shown, the cleaning mechanism 5 includes a lever arm 500, a guide frame 501, and two sets of cleaning rollers 502; the lever arm 500 is mounted on the frame 4; the guide frame 501 is mounted on the side of the lever arm 500; and the two sets of cleaning rollers 502 are mounted sequentially on both sides of the guide frame 501.

[0032] Specifically, the two sets of cleaning rollers 502 include two cleaning brush rollers, which are symmetrically arranged on one side of the guide frame 501. The two sets of cleaning rollers 502 are symmetrically arranged on the guide frame 501.

[0033] Specifically, during the cable winding or unwinding process, the outer surface of the cable can come into contact with various cleaning rollers, allowing the cleaning rollers to clean dust and impurities from the outer surface of the cable.

[0034] like Figure 4As shown, the cleaning mechanism 5 also includes a slide rod 503 slidably disposed on the side of the guide frame 501; a pressure plate 504 is disposed at the top of the slide rod 503; a pull bar 505 is disposed at the bottom of the slide rod 503; a spring 506 is disposed in the middle of the slide rod 503 between the pressure plate 504 and the guide frame 501; a pair of limiting bars 507 are disposed on the side of the guide frame 501, and the pull bar 505 can rotate to contact the two limiting bars 507, so that the pressure plate 504 is separated from the cable.

[0035] Specifically, after the cable pull-out position is determined, the pull bar 505 can be rotated to make the pull bar 505 staggered from the two limiting bars 507. Then the spring 506 extends, so that the side of the pressure plate 504 presses against the side of the cable to fix the cable. At the same time, when winding the cable, it can prevent the cable end from dragging on the ground.

[0036] like Figure 3 As shown, the drive unit 6 is connected to the take-up reel 3 via a transmission belt (chain or toothed belt, etc.). Specifically, the shaft of the take-up reel 3 is connected to the output end of the drive unit 6 via the transmission belt.

[0037] Specifically, to avoid the cable piling up messily on the take-up reel 3 during take-up and untake-up, a cable routing mechanism can be added, such as a lead screw-optical screw structure or chain drive. A cable routing guide is driven by a motor through a gear set. The cable routing guide moves the cable left and right at the take-up reel 3, so that the cable can be wound evenly and neatly on the take-up reel 3, thereby ensuring the uniformity of cable winding.

[0038] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
