Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine electromechanical cables, and particularly relates to a device for replacing coal mine electromechanical cables. Background Technique

[0002] Underground operation equipment such as coal mining machines in coal mines needs to be powered by cables during normal coal mining operations. However, the cables used to supply power to coal mine electromechanical equipment are prone to various problems during use, such as cable breakage and cable outer skin rupture.

[0003] Specifically, due to the complex working conditions in the coal mining area, the service life of the cable is lower than that under normal conditions. Especially during the operation, when the gangue hits the cable during coal mining, the cable needs to be replaced in time. Otherwise, once the cable is damaged and leaks electricity, very serious safety accidents will occur. Specifically, in the roadway of the coal mining area, the concentration of gas is relatively high. Once the cable is damaged, the cable discharge is likely to cause the explosion of gas.

[0004] Therefore, when the cable is damaged or other situations occur, the cable needs to be replaced. In the complex underground environment, only manual dragging of the cable can be used for replacement. However, cables with large diameters and long lengths are relatively heavy. During the dragging process, multiple operators are required to cooperate in dragging. First, due to the smooth surface of the cable, it is very strenuous during the dragging process, which is reflected in the slipping between the cable and the hand during the dragging process. Especially when the underground cable in the mine is dragged from positions such as the drainage ditch, there is water on the surface of the cable. Therefore, it is even more difficult to hold the cable and drag it.

[0005] Secondly, during the work process, due to the relatively heavy cable during the dragging process, the cable can only be dragged while rubbing against the ground. Once the cable touches sharp objects on the ground such as sharp stones, the outer skin of the cable is easily scratched, which further affects the service life of the cable.

[0006] At the same time, during the work process, when replacing the cable, multiple cables are often replaced synchronously. However, due to the large diameter of the cable, only one cable can be dragged to the designated position for replacement at a time, which leads to a very large labor intensity for the entire cable replacement. Content of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a device for replacing coal mine electromechanical cables.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A coal mine electromechanical cable replacement device, including a cable towing mechanism. The cable towing mechanism includes an annular cable towing frame, and a plurality of cable locking components are fixedly connected to the outer side wall of the annular cable towing frame. The cable locking component includes a first clamp plate integrally formed on the outer side wall of the annular cable towing frame, and the first clamp plate is hinged with a second clamp plate;

[0010] The second clamp plate is fastened to the first clamp plate through a handle screw;

[0011] The top of the annular cable towing frame is hinged with a towing handle assembly;

[0012] The coal mine electromechanical cable replacement device further includes cable bundling components arranged on both sides of the annular cable towing frame. The cable bundling component includes a first cable bundling shell, and the first cable bundling shell is hinged with a second cable bundling shell;

[0013] The cable is bound between the first cable bundling shell and the second cable bundling shell;

[0014] The first cable bundling shell and the second cable bundling shell are locked through a locking structure.

[0015] Preferably, the first clamp plate is integrally formed with a rectangular connecting portion, and the rectangular connecting portion is integrally formed on the annular cable towing frame.

[0016] Preferably, a hinge tongue is integrally formed at the lower end of the second clamp plate, and a tongue opening for hinging the hinge tongue is formed at the lower end of the first clamp plate;

[0017] On the top of the first clamp plate and the first clamp plate, a protruding portion is integrally formed, and the protruding portions are fastened through a handle screw. The handle screw includes a handle portion, and a screw portion is integrally formed on the handle portion.

[0018] Preferably, the shapes of the first cable bundling shell and the second cable bundling shell are both semi-conical;

[0019] The upper end of the first cable bundling shell is hinged to the upper end of the second cable bundling shell through a flexible connecting plate.

[0020] Preferably, arc-shaped lip strips are integrally formed at the outer port portions of the first cable bundling shell and the second cable bundling shell;

[0021] The arc-shaped lip strips are used to abut against the bound cable.

[0022] Preferably, the material of the arc-shaped lip strip is elastic rubber material.

[0023] Preferably, the locking structure includes convex columns respectively fixedly connected to the bottom positions of the first cable bundling shell and the second cable bundling shell. A connecting screw is slidably connected between the convex columns, and nuts are threadedly connected to both ends of the connecting screw.

[0024] Preferably, a towing wheel mechanism is hinged to the bottom of the annular cable towing frame;

[0025] The towing wheel mechanism includes a towing wheel frame, and driving rollers are rotatably connected to both ends of the towing wheel frame.

[0026] Preferably, a hinge seat is fixedly connected to the top of the towing wheel frame, a hinge rod is hinged to the hinge seat, and the hinge rod is fixedly connected to the bottom of the annular cable towing frame.

[0027] The utility model has the following beneficial effects:

[0028] 1. Through the annular cable towing frame and the first clamping plate and the first clamping plate structure, the cable is locked to the first clamping plate and the second clamping plate. During the working process, in this way, multiple cables can be synchronously towed in an easier-to-tow manner, solving the defect that it is difficult to hold and tow especially large-caliber cables. At the same time, the above method greatly reduces the defect that the cable skin is damaged due to rubbing against the ground during the cable towing process.

[0029] 2. When towing the cable, after the cable is locked, the cable is pushed towards the first cable bundling shell and the second cable bundling shell, and then the first cable bundling shell and the second cable bundling shell are combined. At this time, the cable is bound in the conical cavity formed by the first cable bundling shell and the second cable bundling shell. The first cable bundling shell and the second cable bundling shell firmly bind the cable. After binding, the cable is concentrated and does not disperse, making it more convenient to tow multiple cables.

[0030] At the same time, in order to avoid friction between the cable and the first cable bundling shell and the second cable bundling shell, arc-shaped lip strips are integrally formed at the outer port parts (i.e., the small-mouth parts) of the first cable bundling shell and the second cable bundling shell; when the cable is bound, under the limitation of the conical structure and the limitation of the outer port parts of the first cable bundling shell and the second cable bundling shell, the cable is concentrated towards the central position and abuts against the arc-shaped lip strips. The arc-shaped lip strips are made of elastic rubber material, so under the action of the arc-shaped lip strips, the cable is further concentrated and bound.

[0031] The first cable bundling shell and the second cable bundling shell are respectively fixed to the outer side wall of the annular cable towing frame through pull ropes. The pull ropes have a certain length, so there is a certain distance between the first cable bundling shell and the second cable bundling shell and the annular cable towing frame. At the same time, it is avoided that the first cable bundling shell and the second cable bundling shell move away from the annular cable towing frame during towing, resulting in cable dispersion.

[0032] 3. The towing wheel mechanism realizes the movement and towing in the way of rolling of the rollers during the cable towing process, achieving labor-saving towing. Description of the Drawings

[0043] Embodiment 1

[0044] As Figures 1-5 shown, a device for replacing electromechanical cables in coal mines includes a cable towing mechanism. The cable towing mechanism includes an annular cable towing frame 1, and a plurality of cable locking components 2 are fixedly connected to the outer side wall of the annular cable towing frame 1. Each cable locking component 2 locks a strand of cable. During the actual working process, multiple cable towing mechanisms are used in cooperation according to the length of the cable. After locking a certain length of cable, it is towed, and each worker tows a cable towing mechanism. Thus, multiple strands of cable can be towed synchronously.

[0045] Specifically, the cable locking component 2 includes a first clamping plate 21 integrally formed on the outer side wall of the annular cable towing frame 1 (the first clamping plate 21 is integrally formed with a rectangular connecting portion 211, and the rectangular connecting portion 211 is integrally formed on the annular cable towing frame 1). The first clamping plate 21 is hinged with a second clamping plate 22; the second clamping plate 22 is fastened to the first clamping plate 21 by a handle screw.

[0046] Specifically, a hinge tongue 221 is integrally formed at the lower end of the second clamping plate 22, and a tongue opening for hinging the hinge tongue 221 is formed at the lower end of the first clamping plate 21. Protrusions are integrally formed at the tops of the first clamping plate 21 and the first clamping plate 21, and the protrusions are fastened by a handle screw 222. The handle screw 222 includes a handle portion, and a screw portion is integrally formed on the handle portion.

[0047] During the working process, the cables are locked to each cable locking component 2 according to the number of cable strands. Preferably, the cables are locked at equal intervals to keep the center of gravity stable.

[0048] Specifically, after unscrewing the handle screw, the cable is locked into the cable locking component 2, and the handle screw is fastened. At this time, the cable is in a locked state.

[0049] Meanwhile, a towing handle assembly is hinged to the top of the annular cable carrier 1. Specifically, the towing handle assembly includes a hinged pull rod 32 hinged to the top of the annular cable carrier 1 (a pair of hinged ears 31 are fixed to the top of the annular cable carrier 1), and a handle ring 321 is hinged to the top of the hinged pull rod. After the operator locks the cable, the operator drags it by pulling the handle ring 321 by hand. In this way, it is convenient to drag the cable with a large diameter after locking.

[0050] Embodiment 2

[0051] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, after the cable is locked in the above manner, in order to bind the multi-strand cable to the central position and prevent the cable from swaying outward during the cable dragging process, resulting in the cable being too scattered and inconvenient to drag, the above coal mine electromechanical cable replacement device further includes a cable binding assembly arranged on both sides of the annular cable carrier 1. The cable binding assembly includes a first cable binding shell 41, and a second cable binding shell 42 is hinged to the first cable binding shell 41; the cable is bound between the first cable binding shell 41 and the second cable binding shell 42.

[0052] Specifically, the shapes of the first cable binding shell 41 and the second cable binding shell 42 are both semi-conical; the upper end of the first cable binding shell 41 is hinged to the upper end of the second cable binding shell 42 through a soft connecting plate A (the soft connecting plate A is an integrally formed rubber plate at the upper ends of the two cable binding shells). The inner ends (the ends facing the annular cable carrier 1) of the first cable binding shell 41 and the second cable binding shell 42 are large-mouth ends, and the outer ends are small-mouth ends, and there is a certain distance from the annular cable carrier 1.

[0053] After pushing the cable towards the first cable binding shell 41 and the second cable binding shell 42, the first cable binding shell 41 and the second cable binding shell 42 are combined. At this time, the cable is bound in the conical cavity formed by the first cable binding shell 41 and the second cable binding shell 42.

[0054] The above first cable binding shell 41 and the second cable binding shell 42 are locked through a locking structure to lock the bound cable. Specifically, the locking structure includes protruding columns 441 respectively fixedly connected to the bottom positions of the first cable binding shell 41 and the second cable binding shell 42. A connecting screw rod 442 is slidably connected between the protruding columns 441, and nuts are threadedly connected to both ends of the connecting screw rod 442.

[0055] After the cable is locked, the connecting screw rod 442 is passed through the through holes on the protruding columns 441, and the nuts are tightened. At this time, the first cable binding shell 41 and the second cable binding shell 42 firmly bind the cable. After binding, the cable is concentrated and not scattered, making it more convenient to drag the multi-strand cable.

[0056] Meanwhile, to avoid friction between the cable and the first cable sheath 41 and the second cable sheath 42, arc-shaped lip strips 43 are integrally formed at the outer port portions (i.e., the small-mouth portions) of the first cable sheath 41 and the second cable sheath 42. After the cable is constrained, under the limitation of the conical structure and the limitation of the outer port portions of the first cable sheath 41 and the second cable sheath 42, the cable converges towards the central position and abuts against the arc-shaped lip strips 43. The arc-shaped lip strips 43 are made of elastic rubber material, so that under the action of the arc-shaped lip strips 43, the cable is further concentrated and constrained.

[0057] The first cable sheath 41 and the second cable sheath 42 are respectively fixed on the outer side wall of the annular cable towing frame 1 through pull ropes 6. The pull ropes 6 have a certain length, so there is a certain distance between the first cable sheath 41, the second cable sheath 42 and the annular cable towing frame 1. At the same time, it is avoided that the first cable sheath 41 and the second cable sheath 42 move away from the annular cable towing frame 1 during the dragging process, resulting in the dispersion of the cable.

[0058] Embodiment 3

[0059] As Figures 1-5 shown, on the basis of the structure of Embodiment 2, in order to achieve labor-saving dragging during the process of dragging the cable, a towing wheel mechanism is hinged at the bottom of the above-mentioned annular cable towing frame 1. The towing wheel mechanism includes a towing wheel frame 5, and driving rollers 51 are respectively rotatably connected to both ends of the towing wheel frame 5. A hinge seat 52 is fixedly connected to the top of the towing wheel frame 5, and a hinge rod 521 is hinged to the hinge seat 52, and the hinge rod 521 is fixedly connected to the bottom of the annular cable towing frame 1.

[0060] During the working process, the operator drags the entire device, loads part of the gravity on the towing wheel mechanism, and realizes dragging in a rolling movement manner during the process of dragging the cable, so as to achieve labor-saving dragging. After the cable is dragged to the target position, the operator releases the annular cable towing frame 1 and the cable being dragged, so as to release the cable.

[0061] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
