Technical Field
[0001] This utility model relates to the field of electrical wiring protection technology in coal mines, specifically a wiring connection structure for electrical equipment in coal mines. Background Technology
[0002] The wiring connection structure in coal mine electromechanical equipment forms an indispensable cornerstone of the coal mine production process. It precisely ensures the smooth transmission of power and the stable connection of signals between equipment, which is a prerequisite for maintaining the efficient operation of the coal mine production system. In the current practice of wiring and installing coal mine electromechanical equipment, the wire sleeve and the junction box are connected. The junction box is connected to the electromechanical equipment, and the screw fastening action achieves a firm connection with the electromechanical equipment, which facilitates the orderly connection of the various lines inside the wire sleeve to the inside of the electromechanical equipment.
[0003] However, in practical applications, the wire sleeves installed on the casings of wired coal mine electromechanical equipment often exhibit significant pulling resistance. Due to the dim lighting inside coal mine tunnels and the fact that wires are usually laid on the ground, workers or various transportation equipment are very likely to accidentally pull on the wire sleeves when passing through. Since the wire sleeves are fixed inside the junction box, this pulling makes it difficult to easily break the wire sleeves and pull them out of the junction box, which may lead to damage to the electromechanical equipment or even personal injury accidents. Therefore, we propose a wiring connection structure for coal mine electromechanical equipment. Utility Model Content
[0004] One of the technical problems to be solved in this application is: how to design a wiring connection structure for coal mine electromechanical equipment that can be quickly disconnected when pulled.
[0005] To address the aforementioned technical problems, this application provides a wiring connection structure for coal mine electromechanical equipment, including an upper cover plate and a lower cover plate movably mounted on the upper cover plate. An electromechanical wire is disposed inside the upper cover plate, and a wire sleeve is movably disposed inside the lower cover plate. A wiring module is disposed between the electromechanical wire and the wire sleeve. The structure also includes:
[0006] A movable ring, wherein the movable ring is sleeved on the outer surface of the wire sleeve;
[0007] Iron balls, wherein multiple iron balls are movably disposed inside the lower cover plate and are movably disposed in a movable ring;
[0008] The disconnect component is located inside the lower cover plate. When the wire sleeve drives the movable ring to move rapidly, it can squeeze multiple iron balls, so that the iron balls can drive the disconnect component to move freely, allowing the movable ring to quickly pass through the lower cover plate and avoid directly damaging the wiring module.
[0009] In some embodiments, the disconnecting component includes a fixing tube disposed inside the lower cover plate. The outer surface of the fixing tube is provided with a plurality of square grooves, and the inner walls of the plurality of square grooves are provided with circular grooves. The plurality of square grooves are connected to the interior of the fixing tube through corresponding circular grooves, and the plurality of iron balls are respectively movably disposed on the inner walls of the corresponding circular grooves.
[0010] In some embodiments, a push ring is movably disposed on the outer surface of the fixed tube, and a connecting cylinder is disposed on the end face of the push ring. Both the push ring and the connecting cylinder are movably disposed inside the lower cover plate. The inner wall of the connecting cylinder is provided with an arc-shaped inclined surface, so that the arc-shaped inclined surface of the connecting cylinder is closely attached to the outer surface of the iron ball.
[0011] In some embodiments, a limiting ring is sleeved on the outer surface of the connecting cylinder inside the fixing tube, and a spring is sleeved on the outer surface of the fixing tube. The two ends of the spring are respectively disposed on the inner wall of the connecting cylinder and the end face of the limiting ring. A bending assembly for resetting the wire sleeve after bending and elongation is disposed inside the lower cover plate.
[0012] In some embodiments, the bending assembly includes a fixing ring fitted onto the outer surface of the wire sheath, a connecting plate is provided at the bottom of the inner wall of the lower cover plate, a groove is provided at the top of the connecting plate, a sliding rod is provided on the outer surface of the fixing ring, a slider is movably arranged on the inner wall of the groove, and the bottom end of the sliding rod is located at the top of the slider.
[0013] In some embodiments, straight grooves are provided on both sides of the inner wall of the slide, and ball bearings are movably embedded on both sides of the slider. The two ball bearings are movably disposed on the inner wall of the straight groove. A guide post is provided on the inner wall of the slide, and the slider is movably disposed on the guide post. A second spring is sleeved on the outer surface of the guide post, and the end face of the second spring is disposed on the side of the slider.
[0014] In some embodiments, the end face of the push ring is provided with a beveled ring, the side of the lower cover plate is provided with a limiting shell, the inner wall of the limiting shell is movably provided with a beveled plate, the beveled surface of the beveled plate is movably provided on the outer surface of the beveled ring, and the side of the beveled plate is movably provided on the end face of the push ring away from the beveled ring.
[0015] This utility model has at least the following beneficial effects:
[0016] 1. Through the cleverly designed movable ring on the wire sleeve, when the wire sleeve is pulled quickly and reaches the preset force threshold, the movable ring can immediately contact the iron ball, causing the iron ball to apply pressure to the disconnect component, thereby causing the disconnect component to lose its limiting function for the iron ball. At this time, the iron ball can move freely, and even when passing through the limiting ring on the wire sleeve, it can no longer be effectively limited. This mechanism ensures that even if the wire sleeve is accidentally pulled, the internal wiring module can be effectively protected from damage, thereby greatly improving the safety during the mine construction process.
[0017] 2. The bending component can bend the wire sleeve inside the upper and lower cover plates. When the wire sleeve is pulled, the bending component can be used to pull out the pre-bent wire sleeve. When used with the disconnect component, it can be reset after being pulled, thereby reducing the possibility of secondary accidents. Attached Figure Description

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a wiring connection structure for coal mine electromechanical equipment, including an upper cover plate 1 and a lower cover plate 2 movably disposed on the upper cover plate 1. An electromechanical wire 4 is disposed inside the upper cover plate 1, and a wire sleeve 3 is movably disposed inside the lower cover plate 2. A wiring module 6 is disposed between the electromechanical wire 4 and the wire sleeve 3. The wire sleeve 3 is bent inside the upper cover plate 1 and the lower cover plate 2. The structure also includes:
[0029] The movable ring 8 is fitted onto the outer surface of the wire sleeve 3;
[0030] Iron balls 9 are movably disposed inside the lower cover plate 2. There are multiple iron balls 9, and they are movably disposed in the movable ring 8. The iron balls 9 are circumferentially distributed inside the lower cover plate 2.
[0031] Disconnect component 5 is located inside the lower cover plate 2. When the wire sleeve 3 drives the movable ring 8 to move rapidly, it can squeeze multiple iron balls 9, so that the iron balls 9 can drive the disconnect component 5 to move freely, allowing the movable ring 8 to quickly pass through the lower cover plate 2, thus avoiding direct damage to the wiring module 6.
[0032] The disconnecting component 5 includes a fixing tube 55 disposed inside the lower cover plate 2. The outer surface of the fixing tube 55 is provided with multiple square grooves 57. The inner wall of each of the multiple square grooves 57 is provided with a circular groove 56. The multiple square grooves 57 are connected to the inside of the fixing tube 55 through the corresponding circular grooves 56. Multiple iron balls 9 are respectively movably disposed on the inner wall of the corresponding circular grooves 56. The iron balls 9 can move in the corresponding circular grooves 56, but cannot completely detach from the circular grooves 56.
[0033] A push ring 51 is movably provided on the outer surface of the fixed tube 55. A connecting cylinder 53 is provided on the end face of the push ring 51. Both the push ring 51 and the connecting cylinder 53 are movably provided inside the lower cover plate 2. The inner wall of the connecting cylinder 53 is provided with an arc-shaped inclined surface. Therefore, the arc-shaped inclined surface of the connecting cylinder 53 is closely attached to the outer surface of the iron ball 9. By squeezing the iron ball 9 through the arc-shaped inclined surface of the connecting cylinder 53, the iron ball 9 can achieve a limiting effect and prevent the movable ring 8 from detaching.
[0034] A limiting ring 52 is fitted on the outer surface of the fixed tube 55 inside the connecting tube 53. A spring 54 is fitted on the outer surface of the fixed tube 55. The two ends of the spring 54 are respectively set on the inner wall of the connecting tube 53 and the end face of the limiting ring 52. A bending component 7 is provided inside the lower cover plate 2 for resetting the wire sleeve 3 after bending and elongation. The force required for the movable ring 8 to disengage is the force of the connecting tube 53 squeezing the spring 54.
[0035] The bending assembly 7 includes a fixing ring 71 fitted onto the outer surface of the wire sleeve 3. A connecting plate 73 is provided at the bottom of the inner wall of the lower cover plate 2. A groove 75 is provided at the top of the connecting plate 73. A sliding rod 72 is provided on the outer surface of the fixing ring 71. A slider 77 is movably provided on the inner wall of the groove 75. The bottom end of the sliding rod 72 is located at the top of the slider 77. By setting the fixing ring 71 on the outer surface of the wire sleeve 3 and setting the fixing ring 71 in a staggered manner, the wire sleeve 3 can be bent.
[0036] The inner wall of the slide groove 75 has straight grooves 74 on both sides. The two sides of the slider 77 are movably embedded with balls 76. The two balls 76 are movably disposed on the inner wall of the straight grooves 74. The inner wall of the slide groove 75 is provided with guide posts 78. The slider 77 is movably disposed on the guide posts 78. The outer surface of the guide posts 78 is fitted with a second spring 79. The end face of the second spring 79 is disposed on the side of the slider 77. The spring is designed so that after the wire sleeve 3 pulls the fixed ring 71 to move, it slides inside the fixed ring 71. At this time, it quickly returns to its original position by the action of the second spring 79.
[0037] When using this device, the lower cover plate 2, wire sleeve 3, upper cover plate 1, and motor wire 4 must first be installed. When the transport equipment or personnel accidentally pull on the wire sleeve 3, the wire sleeve 3 will cause the movable ring 8 on its outer surface to squeeze the iron ball 9, causing it to shift. The iron ball 9 will then squeeze the arc-shaped inclined surface of the connecting cylinder 53, causing the connecting cylinder 53 to drive the push ring 51 to slide on the outer surface of the fixed tube 55. Meanwhile, the inner wall of the connecting cylinder 53 will squeeze the spring 54, causing it to deform. Simultaneously, the movable ring 8 can pass through the iron ball 9, completing its extension. At this time, the wire sleeve 3 will pull the fixed ring 71 to move, and the multiple fixed rings 71 will gradually form a straight line. The sliding rod 72 slides on the inner wall of the groove 75. The sliding rod 72 drives the slider 77 to slide inside the groove 75. The slider 77 slides on the outer surface of the guide post 78. The compression spring 79 is installed. At this time, the vehicle may not be able to notice, but the staff will notice in time. Just release the pulling wire sleeve 3. The slider 77 will reset in the spring 79. At this time, the slider 77 will drive the fixing ring 71 and the sliding rod 72 to reset. After completion, the movable ring 8 cannot directly return to the inside of the lower cover plate 2. Just pull the push ring 51. At this time, the spring 79 will release the incomplete reset distance again, drive the slider 77 to press against the inner wall of the groove 75, so that the movable ring 8 is limited by the iron ball 9 again.
[0038] Example 2: Please refer to Figure 7-8 This utility model provides a technical solution: the end face of the push ring 51 is provided with a sloping ring 10, the side of the lower cover plate 2 is provided with a limiting shell 11, the inner wall of the limiting shell 11 is movably provided with a sloping plate 12, the sloping surface of the sloping plate 12 is movably provided on the outer surface of the sloping ring 10, and the side of the sloping plate 12 is movably provided on the end face of the push ring 51 away from the sloping ring 10. The sloping plate 12 can be stuck inside the push ring 51 after the push ring 51 is pulled, so that it can be detected and adjusted in time.
