Description

Technical Field

[0001] The invention belongs to the technical field of electrical construction, and in particular relates to an auxiliary device for laying mine electrical lines. Background Art

[0002] During mine construction, in order to meet the electricity needs of workers and equipment, it is necessary to lay electrical lines and install components such as mine explosion-proof and intrinsically safe combination switches. In order to protect the wires, when laying the lines, it is often necessary to first lay the wire conduits according to the design plan, and then pass the wires through the conduits to achieve the purpose of protecting the wires. The operation of passing the wires through the conduits to complete the installation is called threading.

[0003] The wiring in the mine is complex. If there is any damage, it will be difficult to repair it later. Therefore, when threading the wires or installing components such as combination switches, in order to ensure the safety of electricity use in the later stage and reduce maintenance costs, it is necessary to check whether the surface of the wires is damaged. Usually, the staff judge whether the wires are damaged by observing the surface of the wires with the naked eye. In the early construction process of the mine, the lighting is relatively dim, which can easily cause omissions by the staff. In addition, the threading operation usually involves one person feeding the wire at one end of the wire tube and one person pulling the wire at the other end. If the wire tube is long, when the wire feeding personnel find damage, the feedback may be delayed, reducing construction efficiency. Summary of the Invention

[0026] Furthermore, the secondary adjustment block 7 includes a U-shaped plate 701, a spring 702 and a through hole 703. The U-shaped plate 701 is slidably arranged between the extension plates 502, the open end of the U-shaped plate 701 is arranged toward the center of the ring body 201, the spring 702 is arranged between the U-shaped plate 701 and the slider 501, and the through hole 703 is symmetrically opened on the side walls at both ends of the U-shaped plate 701.

[0027] Furthermore, the detection wheel 8 includes a roller 801 and a clamping shaft 803, and the clamping shaft 803 is symmetrically arranged on both sides of the roller 801. The roller 801 is rotatable on the inner side of the U-shaped plate 701 through the clamping shaft 803 and the through hole 703. The clamping shaft 803 extends through the through hole 703 to the second slide groove 504. The side wall of the clamping shaft 803 located in the second slide groove 504 is provided with friction patterns, and the circumferential side wall of the roller 801 is provided with friction teeth 802.

[0028] In the initial state, the spring 702 pushes the U-shaped plate 701 toward the center of the ring body 201 , and the clamping shaft 803 engages with the clamping teeth 505 .

[0029] Furthermore, an indicator groove 207 is formed through the top wall of one of the slide grooves 202 , and an indicator rod 506 is provided on the top of the threaded cylinder 503 of one of the detection units 4 , and the indicator rod 506 is slidably disposed in the indicator groove 207 .

[0030] Furthermore, the limiting ring 3 includes an auxiliary ring 301 and limiting rods 302 . The auxiliary ring 301 is arranged above the boss 204 , and the limiting rods 302 are arranged in a circular array on the side wall of the auxiliary ring 301 .

[0031] When in use, first adjust according to the size of the wire, rotate the swivel 102, the bevel gear ring 103 on the top surface of the swivel 102 synchronously drives the bevel gear 602 of all the detection units 4 to rotate, the bevel gear 602 drives the threaded rod 603 to rotate, the threaded rod 603 rotates to adjust the position of the threaded cylinder 503, thereby adjusting the position of the first-level adjustment block 5, thereby increasing or decreasing the distance between the rollers 801 to make it meet the size of the wire, and observing the position of the indicator rod 506 in the indicator groove 207 during adjustment. After the adjustment is completed, the staff responsible for feeding the wire will place the limit ring 3 provided in the present invention. The guide wire 206 is connected to the guide wire of the auxiliary threading operation, and the guide wire and the wire are passed through the middle of the base tube 1 and fed into the wire tube for use. During the feeding process, the side wall of the wire pushes the detection wheel 8 outward to make the clamping shaft 803 away from the clamping teeth 505. After the clamping shaft 803 is free from the restriction of the clamping teeth 505, the roller 801 can rotate freely under the drive of the side wall of the wire. At the same time, the elastic telescopic rod 205 and the auxiliary wheel 206 clamp the wire to center the wire. As the threading operation proceeds, when the damaged point of the wire skin passes through the roller 801, it is located at the damaged point. The roller 801 in the damaged position loses the support of the intact surface of the wire, and the spring 702 pushes the U-shaped plate 701 back to the center of the ring body 201, so that the roller 801 moves toward the center of the ring body 201, thereby causing the card shaft 803 to bite with the card tooth 505. The roller 801 cannot rotate freely, and is engaged with the damaged part of the wire under the action of the friction force generated by the friction tooth 802 and the pressure generated by the spring 702. At this time, if the staff who pulls the wire continues to pull the wire, the detection ring 2 will overcome the magnetic connection between the socket 104 and the buckle 208, and the buckle 208 will be separated from the socket 104, and the detection ring 2 will be separated from the base tube 1. And it moves with the wire. If the wire feeding personnel does not notify the wire pulling personnel in time, then when the limit ring 3 passes through the wire tube opening, the limit rod 302 will press against the wire tube opening to restrict the wire from continuing to move. The wire pulling personnel will feel obvious resistance, which provides timely feedback to the staff at the wire pulling end and improves work efficiency. When wiring components such as mine explosion-proof and intrinsically safe combination switches, the end of the cable close to the component is passed through the present invention from one end of the detection ring 2. After the cable is fixed on the component interface, the present invention is pulled in the direction away from the combination switch and other components, and the cable connected to the component can be detected along the side wall of the cable.
