Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable dragging device for advanced cables in fully mechanized mining faces. Background Technology

[0002] In fully mechanized coal mining operations, cables need to be dragged and laid out as the mining equipment moves. However, due to the complex working environment, such as uneven ground and rock debris accumulation, cables are prone to wear, tangling, and even breakage, directly affecting the normal operation and production efficiency of the mining equipment. Therefore, a cable dragging device for advanced cables in fully mechanized coal mining faces is needed.

[0003] An existing cable-dragging device for advanced cables in fully mechanized mining faces (publication number: CN221126756U) has at least the following drawbacks: Although the device can adjust the lifting height of the cable, it cannot adapt to the slope of the mine tunnel, which means that the cable may still come into contact with the inner wall of the mine tunnel due to the complex environment inside the tunnel, causing wear. In addition, the device uses a sling to support the cable, which results in greater friction between the cable and the sling when dragging, which may cause wear to the cable. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable-dragging device for advanced cables in fully mechanized mining faces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable-dragging device for advanced cables in a fully mechanized mining face includes a base, a fixed cylinder above the base, a movable guide roller inside the fixed cylinder near the right side, a fixed guide roller inside the fixed cylinder near the left side, and an adjustment assembly between the base and the fixed cylinder. The adjustment assembly includes two screws located on the bottom surface of the fixed cylinder near the front and rear sides. A first threaded cylinder is threadedly connected to the outer wall of the screw near the front side of the fixed cylinder, and a second threaded cylinder is threadedly connected to the outer wall of the screw near the rear side of the fixed cylinder.

[0007] As a further embodiment of this utility model, a first rotating seat is fixed to the top surface of the base near the rear side, a second threaded cylinder is fixed to the outer wall of the first rotating seat shaft, the first threaded cylinder is fixed to the top surface of the base near the front side, and a second rotating seat is fixed to the bottom surface of the fixed cylinder near both the front and rear sides. The top end of the screw is rotatably connected to the outer wall of the second rotating seat shaft. A drive frame is slidably inserted into the left side of the outer wall of the fixed cylinder, and an adjusting screw is threadedly connected to the left side of the drive frame. One end of the adjusting screw is rotatably connected to the left side of the outer wall of the fixed cylinder, and the movable guide roller is located inside the drive frame.

[0008] As a further embodiment of this utility model, both the movable guide roller and the fixed guide roller are rotatably connected to the interior of the drive frame and the interior of the fixed cylinder, respectively, using damping bearings.

[0009] As a further embodiment of this utility model, mounting holes are provided at the four corners of the top surface of the base.

[0010] As a further embodiment of this utility model, two connecting frames are provided on both the front and rear sides of the fixed cylinder, and a brush is fixed inside the connecting frame.

[0011] As a further embodiment of this utility model, a plurality of mounting bolts are slidably inserted on one side of the connecting frame, and the mounting bolts are threadedly connected to the fixing cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up movable and fixed guide rollers to support and guide the cable, the cable moves between the movable and fixed guide rollers when dragged, causing them to rotate. This effectively protects the cable from wear and tangling. By adjusting the lead screw, the height of both ends of the base can be adjusted individually or simultaneously, allowing the base to tilt back and forth or be adjusted in height. This adapts to the complex environment inside the mine tunnel and prevents the supported cable from hitting the inner wall of the mine tunnel due to slope factors, increasing the applicability of the device.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4 As shown, a cable-dragging device for advanced cables in a fully mechanized mining face includes a base 1. A fixed cylinder 101 is arranged above the base 1. A movable guide roller 102 is arranged inside the fixed cylinder 101 near the right side, and a fixed guide roller 103 is arranged inside the fixed cylinder 101 near the left side. An adjustment assembly is arranged between the base 1 and the fixed cylinder 101. The adjustment assembly includes two lead screws 2 arranged on the bottom surface of the fixed cylinder 101 near the front and rear sides. A first threaded cylinder 201 is threadedly connected to the outer wall of the lead screw 2 near the front side of the fixed cylinder 101, and a second threaded cylinder 202 is threadedly connected to the outer wall of the lead screw 2 near the rear side of the fixed cylinder 101.

[0023] like Figures 2-4As shown, in this embodiment, a first rotating seat 203 is fixed to the top surface of the base 1 near the rear side. A second threaded cylinder 202 is fixed to the outer wall of the rotating shaft of the first rotating seat 203. The first threaded cylinder 201 is fixed to the top surface of the base 1 near the front side. A second rotating seat 204 is fixed to the bottom surface of the fixed cylinder 101 near both the front and rear sides. The top end of the screw 2 is rotatably connected to the outer wall of the rotating shaft of the second rotating seat 204. A drive frame 205 is slidably inserted into the left side of the outer wall of the fixed cylinder 101. An adjusting screw 206 is threadedly connected to the left side of the drive frame 205. One end of the adjusting screw 206 is rotatably connected to the left side of the outer wall of the fixed cylinder 101. The movable guide roller 102 is also located inside the drive frame 205. By rotating the adjusting screw 206, under the action of the threaded connection between the drive frame 205 and the adjusting screw 206, the drive frame 205 drives the movable guide roller 102 toward the fixed guide roller 103.

[0024] Approaching and abutting against the outer wall of the cable, and then, depending on the internal conditions of the mine tunnel, by rotating the two lead screws 2, with the two lead screws 2 respectively connected to the outer walls of the first threaded cylinder 201 and the second threaded cylinder 202, the synchronous rotation of the lead screws 2 will drive the base 1 and the cable to be lifted as a whole. When only the lead screw 2 close to the rear side of the base 1 is rotated, the base 1 will be deflected back and forth, which is convenient to adapt to the complex environment inside the mine tunnel and prevent the supported cable from abutting against the inner wall of the mine tunnel due to the slope factor, thus increasing the applicability of the device.

[0025] like Figures 2-4 As shown, in this embodiment, both the movable guide roller 102 and the fixed guide roller 103 are rotatably connected to the interior of the drive frame 205 and the interior of the fixed cylinder 101 respectively using damping bearings. By using damping bearings to rotatably connect the movable guide roller 102 and the fixed guide roller 103 to the interior of the drive frame 205 and the interior of the fixed cylinder 101 respectively, the movable guide roller 102 and the fixed guide roller 103 are subjected to a certain damping effect during rotation, which effectively prevents the cable from continuing to move due to inertia when dragged, thus preventing the cable from becoming loose and bent.

[0026] like Figures 2-4 As shown in this embodiment, mounting holes 3 are provided at the four corners of the top surface of the base 1. By inserting expansion bolts into the mounting holes 3, the base 1 can be installed on the bottom or side of the mine tunnel to support the cable.

[0027] like Figure 2 one Figure 4As shown in this embodiment, two connecting frames 4 are provided on the front and rear sides of the fixed cylinder 101. A brush 401 is fixed inside the connecting frame 4. By setting the brush 401, the outer wall of the cable can be cleaned to prevent impurities on the cable from being carried to the movable guide roller 102 and the fixed guide roller 103, causing impurities to block the gap between the movable guide roller 102 and the fixed guide roller 103, making the cable unable to move.

[0028] like Figure 2 one Figure 4 As shown in this embodiment, a plurality of mounting bolts 402 are slidably inserted on one side of the connecting frame 4. The mounting bolts 402 are threadedly connected to the fixing cylinder 101. The connection between the connecting frame 4 and the fixing cylinder 101 via the mounting bolts 402 facilitates disassembly, cleaning, or replacement of the brush 401.

[0029] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, by passing the cable through the inside of the fixed cylinder 101, the brush 401 abuts against the outer wall of the cable, and at this time the cable is located between the movable guide roller 102 and the fixed guide roller 103. Then, by rotating the adjusting screw 206, under the action of the threaded connection between the drive frame 205 and the adjusting screw 206, the drive frame 205 drives the movable guide roller 102 to approach the fixed guide roller 103 and abut against the outer wall of the cable. Then, according to the internal conditions of the mine, by rotating the two lead screws 2, under the action of the threaded connection between the two lead screws 2 and the outer wall of the first threaded cylinder 201 and the second threaded cylinder 202 respectively, when the lead screws 2 are rotated synchronously, the base 1 and the cable will be lifted as a whole. When only the lead screw 2 close to the rear side of the base 1 is rotated, the base 1 will be deflected back and forth, which is convenient to adapt to the complex environment inside the mine and prevent the slope factor from causing the supported cable to abut against the inner wall of the mine, thus increasing the applicability of the device.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
