Description

Technical Field

[0001] The utility model relates to the technical field of power supply and distribution cables, in particular to a power supply and distribution cable retracting and releasing device for open-pit mines. Background Art

[0002] Open-pit mine power distribution cables are specialized cables used to provide power to various equipment and facilities in open-pit mines. These cables are used in open-pit environments and therefore require high durability, safety, and reliability.

[0003] However, in the daily maintenance and management of cables, especially in the winding and storage of cables, the existing technology has obvious shortcomings. Specifically, when the cable needs to be wound, the operator usually needs to manually fix one end of the cable on the surface of the winding wheel first. This process is not only time-consuming and labor-intensive, but also inefficient. Since the existing winding wheel lacks the function of automatically fixing the cable, the operator must continue to hold one end of the cable by hand until the cable is wound to a certain extent by the winding wheel before letting go. This operation method increases the labor intensity of the operator and the winding efficiency is low. Utility Model Content

[0021] like Figure 1-Figure 5As shown, the utility model provides a technical solution: an open-pit mine power supply and distribution cable retracting device, including a mounting base 1, a support frame 2 is fixed on the top of the mounting base 1, a reel 3 is rotatably connected to the inner side of the support frame 2, a motor 4 is fixed on the surface of the support frame 2, the output shaft of the motor 4 passes through the support frame 2, and the output shaft of the motor 4 is fixed to the surface of the reel 3, and the surface of the reel 3 is provided with a fixing component 5 for facilitating cable reeling and a linkage component 6 for preventing accidental contact and separation. The fixing component 5 includes: Cavity 1 50, cavity 1 50 is opened inside the winding wheel 3, the inner wall of cavity 1 50 is slidably connected with a slider 51, the surface of the slider 51 is hinged with a connecting rod 53, the end of the connecting rod 53 away from the slider 51 is hinged with a moving block 54, the moving block 54 is slidably connected to the inner wall of cavity 1 50, the fixing component 5 also includes a spring 1 52, one end of the spring 1 52 is fixed to the surface of the slider 51, the end of the spring 1 52 away from the slider 51 is fixed to the inner wall of cavity 1 50, and the surface of the moving block 54 is fixed. There is a spring 2 55, and the end of the spring 2 55 away from the moving block 54 is fixed on the inner wall of the cavity 1 50. A pressure rod 57 is fixed on the side of the moving block 54 away from the spring 2 55. The end of the pressure rod 57 away from the moving block 54 passes through the winding wheel 3. A stabilizing hole 58 is opened on the surface of the winding wheel 3. A clamping plate 56 is fixed on the surface of the slider 51. The end of the clamping plate 56 away from the slider 51 passes through the stabilizing hole 58. A rubber pad is fixed on the side of the clamping plate 56 close to the winding wheel 3. Pressing the pressure rod 57 causes the moving block 54 to move closer. The center of the winding wheel 3 moves, and the angle of the connecting rod 53 is offset, driving the slider 51 and the clamping plate 56 to move away from the winding wheel 3, and the pressure rod 57 is limited by the connecting component 6. At this time, the cable is wound on the surface of the winding wheel 3, and the fixing plate 680 is pulled to make the ring 62 rotate forward again, so that the block 65 can be disengaged from the annular groove 67, and the limit on the pressure rod 57 is released. At this time, the spring 1 52 and the spring 2 55 are released, driving the slider 51 to reset, so that the clamping plate 56 clamps the cable without manual fixation.

[0022] The linkage assembly 6 includes a fixed sleeve 60, which is fixed to the surface of the winding wheel 3. A cavity 2 61 is provided inside the fixed sleeve 60. The inner wall of the cavity 2 61 is rotatably connected to a ring 62. A resistance hole 63 is provided on the surface of the ring 62. The inner wall of the resistance hole 63 is in resistance to a resistance rod 64. A resistance rod 64 is fixed to the surface of the resistance rod 64. A block 65 is fixed to the surface of the resistance rod 64. The block 65 is slidably connected to the inner wall of the cavity 2 61. A spring 3 66 is fixed on the surface of the block 65. One end of the spring 3 66 away from the block 65 is fixed to the inner wall of the cavity 2 61. An annular groove 67 is provided on the surface of the pressure rod 57. The linkage assembly 6 also includes a limiting member 68. The limiting member 68 includes a fixing plate 680. The fixing plate 680 is fixed to the surface of the ring 62. The surface of the fixed sleeve 60 is opened A through hole 681 is provided, and one end of the fixing plate 680 away from the ring 62 passes through the through hole 681. A pin 682 is connected to the surface of the fixing plate 680, and a slot 683 is provided on the surface of the winding wheel 3. The end of the block 65 away from the spring three 66 is set as an inclined surface, and the contact hole 63 is set as an arc. The pressure rod 57 moves downward, so that the block 65 can cooperate with the annular groove 67 to limit the pressure rod 57 to prevent the pressure rod 57 from automatically resetting. When the cable is wound around the surface of the winding wheel 3, the fixing plate 680 is pulled to release the limit of the block 65 and the annular groove 67, so that the pressure rod 57 can be reset normally. The pin 682 is inserted into the fixing plate 680 and the slot 683 to stabilize the ring 62, so that the block 65 cannot continue to move, thereby limiting the pressure rod 57 to prevent accidental contact with the pressure rod 57 and the splint 56 from loosening the cable.

[0023] When the cable needs to be reeled in, the latch 682 is pulled out and the pressure rod 57 is pressed. At this time, the pressure rod 57 drives the moving block 54 to move closer to the center of the reel 3. At this time, the angle of the connecting rod 53 is offset, driving the slider 51 and the clamping plate 56 to move away from the reel 3. At the same time, the spring 1 52 and the spring 2 55 are compressed. At the same time, when the pressure rod 57 moves down, the inner wall of the annular groove 67 contacts the inclined surface of the card block 65, so that the card block 65 enters the cavity 2 61, so that the spring 3 66 is compressed. When the block 65 moves, it drives the contact rod 64 to move synchronously. At this time, the surface of the contact rod 64 contacts the inner wall of the contact hole 63, causing the ring 62 to rotate forward, so that each contact rod 64, contact hole 63, and block 65 move radially synchronously. When the position of the block 65 is parallel to the annular groove 67, the spring 3 66 is released, which can reset the block 65. At the same time, the ring 62 is reversed and reset through the contact rod 64 and the contact hole 63, so that each block 65 enters the annular groove. The locking plate 680 is pulled so that the ring 62 rotates forward again, and the locking block 65 is disengaged from the annular groove 67, thereby releasing the restriction on the pressure rod 57. At this time, the spring 1 52 and the spring 2 55 are released, driving the slider 51 to reset, thereby allowing the clamping plate 56 to clamp the cable. At the same time, the latch 682 is inserted into the fixing plate 680 and the slot 683, which can stabilize the ring 62 and prevent the locking block 65 from moving further, thereby limiting the pressure rod 57 and preventing the clamping plate 56 from releasing the cable by accidentally touching the pressure rod 57. At this time, the motor 4 can be turned forward, and the reel 3 can be reeled in to the cable, thereby improving the reeling efficiency.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
