Description

Technical Field

[0001] The present invention relates to the technical field of cable laying in coal mines, and more specifically, to a cable laying traction device used in coal mines. Background Art

[0002] Cable laying in coal mines refers to the process of installing and arranging cables in accordance with specific requirements and specifications in the coal mine environment. This process involves many aspects, including cable selection, laying methods, suspension requirements, safety protection, etc., to ensure stable operation and power supply safety of cables underground;

[0003] When laying cables, cable supports and hangers are required. Cable supports and hangers can bear the weight of the cable line and effectively prevent the cable from sagging or being tightened, thereby maintaining the stability of the cable line.

[0004] When laying traditional cables, they must first be erected on the support and hanger, and then the cable tightness must be adjusted by continuous pulling to complete the laying. However, when the cable tightness is continuously adjusted, the cable will come into contact with the well wall due to relaxation, which may easily cause damage to the outer wall of the cable. At the same time, after adjusting the tightness of the cable, the multiple groups of cables on the support and hanger must be fixed in sequence, which makes it impossible to keep the cable away from the well wall during pulling. After the pulling is completed, the cable is controlled to fit the well wall to ensure the space for underground action, and the multiple groups of cables are fixed simultaneously to improve the efficiency of cable laying.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that: two fixing holes are opened on the outer walls of both sides of the fixed special-shaped plate 2; when the well wall is relatively flat: the device is fixed on the top of the well wall by fixing the two fixing holes on both sides of the special-shaped plate 2 to ensure the stability of the device;

[0038] like Figure 2-4 As shown in , 7, the traction fixing mechanism 6 includes a groove 61 opened on the traction fixing plate 1, a limit plate 62 is fixedly installed above the groove 61, and a plurality of sets of tooth plates 63 are slidably arranged above the limit plate 62. The plurality of sets of tooth plates 63 are fixedly connected by a connecting sleeve 64, and the connecting sleeve 64 is slidably matched with the limit plate 62. A gear 66 is meshed and connected on the outer wall of the tooth plate 63, and a limit shaft 67 is fixedly arranged at the center of the gear 66;

[0039] The tooth plate 63 is slidably sleeved on the outer wall of the limiting plate 62, and the tooth plate 63 and the connecting sleeve 64 are both limited by the limiting plate 62, thereby ensuring the stability of the tooth plate 63 and the connecting sleeve 64 when moving;

[0040] like Figure 2-4As shown in , 7, the end of the limit shaft 67 is rotatably connected to the groove 61 through a bearing, and a traction frame 68 is fixedly connected to the outer wall of the limit shaft 67. A placement groove 69 is provided above the traction frame 68, and a U-shaped frame 611 is rotatably provided inside the placement groove 69. A limit inclined plate 612 is provided at the bottom of the U-shaped frame 611, and the limit inclined plate 612 is fixedly connected to the placement groove 69. A conveying roller 610 is rotatably provided inside the U-shaped frame 611, and the center line of the conveying roller 610 is parallel to the top of the limit inclined plate 612.

[0041] It should be noted that: the outer wall of the conveying roller 610 is covered with rubber, which can avoid damaging the outer wall of the cable; after multiple cables are successively mounted on the conveying roller 610 from top to bottom, the cables are pulled and laid, and the conveying roller 610 plays a pulling role on the cables. During this process, the cables on the conveying roller 610 are at an appropriate distance from the well wall, thereby avoiding the protrusions on the well wall from damaging the outer wall of the cable, extending the service life of the cable, and facilitating laying;

[0042] like Figure 2-4 As shown in , 7, an arc plate 65 is provided below the gear 66, one end of the arc plate 65 is fixedly connected to the groove 61, and the other end of the arc plate 65 is transmission-matched with the bottom of the U-shaped frame 611;

[0043] like Figure 2-4 As shown in , 7, the top of the traction frame 68 is fixedly connected with a hook 613, the top of the hook 613 is threadedly connected with a fixing bolt 615, the bottom of the fixing bolt 615 is rotatably connected to a limiting arc plate 614 through a bearing, and a rubber pad is provided at the bottom of the limiting arc plate 614;

[0044] It should be noted that when the diameter of the cable is small, the fixing bolt 615 is controlled to rotate to move the limiting arc plate 614 to one side of the conveying roller 610, thereby ensuring that the cable is firmly fixed.

[0045] like Figure 1-2 As shown in , 6, and 8, the bottom set of toothed plates 63 is rotatably connected to an adjusting bolt 616 through a bearing, and the bottom of the adjusting bolt 616 extends to the outside of the traction fixing plate 1 and is fixedly connected to a handle;

[0046] When the cable laying layout is completed, the adjusting bolt 616 at the bottom of the traction fixing plate 1 is controlled to rotate, and the multiple sets of tooth plates 63 are pushed upward, thereby driving the gear 66 to rotate in the opposite direction, and then the traction frame 68 is rotated downward along the limit shaft 67, so that the rear wall of the traction frame 68 is close to one side of the well wall to ensure the working space underground. At the same time, the arc plate 65 pushes the U-shaped frame 611 to one side, so that the conveying roller 610 above the U-shaped frame 611 can synchronously fix the cable;

[0047] In this embodiment, when laying the cable, the conveying roller 610 is kept at an appropriate distance from the well wall when pulling the cable, so as to avoid damage to the outer wall of the cable by the protrusion of the well wall and extend the service life of the cable. After the pulling is completed, the pulling frame 68 is moved closer to one side of the well wall to ensure the working space underground. At the same time, the cable is synchronously fixed by the conveying roller 610 above the U-shaped frame 611, which not only ensures the stability of the cable during the laying process, but also improves the efficiency of cable laying.

[0048] Embodiment 2: Figure 1-2 As shown in 8-9, the present embodiment proposes a cable laying traction device for underground coal mines, which is improved on the basis of the embodiment 1, wherein the mounting mechanism 3 comprises two sets of mounting plates 36 fixedly connected to the rear wall of the traction fixing plate 1, the two sets of mounting plates 36 are symmetrically arranged, a fixed inclined plate 34 is rotatably arranged between the two sets of mounting plates 36, and fixing holes 35 are opened on the outer walls of both sides of the fixed inclined plate 34, and an adjusting bolt 31 is also rotatably arranged on the rear wall of the traction fixing plate 1;

[0049] like Figure 1-2 As shown in , 8-9, a moving block 32 is threadedly connected to the outer wall of the adjusting bolt 31, and a regulating rod 33 is rotatably provided on the outer walls of both sides of the moving block 32, and the end of the regulating rod 33 is rotatably matched with the fixed inclined plate 34; when the well wall is uneven: by controlling the rotation of the adjusting bolt 31, the moving block 32 is moved to one side, thereby adjusting the position of the regulating rod 33, and by pushing the regulating rod 33 upward, the position of the fixed inclined plate 34 is adjusted, so that the device can be fixed above the well wall;

[0050] In this embodiment, the position of the fixed inclined plate 34 in the device is adjusted according to the condition of the well wall, so that the device can be better fixed on the well wall, the stability is improved, and the practicality of the device is improved;

[0051] In the present invention, it can be known from the combination of Example 1 and Example 2 that: multiple cables are sequentially erected above the conveying roller 610, and the rotation of the conveying roller 610 is used to pull the cable to achieve continuous laying of the cable, and the conveying roller 610 is kept at an appropriate distance from the well wall when pulling the cable to avoid damage to the outer wall of the cable by the protrusion of the well wall, thereby extending the service life of the cable, and the reverse rotation of the gear 66 causes the traction frame 68 to rotate downward along the limit shaft 67, so that the traction frame 68 moves closer to one side of the well wall, thereby ensuring the working space underground, and at the same time the arc plate 65 pushes the U-shaped frame 611 to one side, so that the conveying roller 610 above the U-shaped frame 611 synchronously fixes the cable, which not only ensures the stability of the cable during the laying process, but also improves the efficiency of cable laying.

[0052] When the present invention is used, first, the position of the fixed inclined plate 34 or the fixed special-shaped plate 2 is adjusted according to the condition of the shaft wall in the coal mine; when the shaft wall is relatively flat: the device is fixed above the shaft wall by fixing the fixing holes 2 on both sides of the special-shaped plate 2; when the shaft wall is uneven: the adjusting bolt 31 is controlled to rotate, and then the moving block 32 is moved to one side, thereby adjusting the position of the regulating rod 33, and the regulating rod 33 is pushed upward to adjust the position of the fixed inclined plate 34, so as to fix the device above the shaft wall; in the present invention, the position of the fixed inclined plate 34 in the device can be adjusted according to the condition of the shaft wall, so as to better fix the device on the shaft wall and improve stability;

[0053] After multiple cables are successively erected on the top of the conveying roller 610 from top to bottom, the cables are pulled and laid, and the conveying roller 610 plays a traction role on the cables. During this process, the cables on the conveying roller 610 are at an appropriate distance from the well wall, thereby preventing the protrusions on the well wall from damaging the outer wall of the cables during traction, thereby extending the service life of the cables. Subsequently, when the cable laying layout is completed, the adjusting bolt 616 at the bottom of the traction fixing plate 1 is controlled to rotate, and the multiple sets of tooth plates 63 are pushed upward, thereby driving the gear 66 to rotate in the opposite direction, and then the traction frame 68 is rotated downward along the limit shaft 67, as shown in FIG. Figure 7 As shown, the rear wall of the traction frame 68 is moved closer to one side of the well wall to ensure the working space underground. At the same time, the arc plate 65 pushes the U-shaped frame 611 to one side, so that the conveying roller 610 above the U-shaped frame 611 can synchronously fix the cable. The present invention moves the traction frame 68 closer to the well wall by adjusting the bolt 616 upward, thereby ensuring the working space underground and simultaneously completing the fixation of multiple groups of cables, thereby improving the efficiency of cable laying.
