Description

Technical Field

[0001] The present invention relates to the technology of cable detection equipment, and specifically to a performance detection device for cable wires. Background Technique

[0002] Electric wires and cables are wire products used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. In a broad sense, electric wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as an aggregate composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, general protective layers, and outer protective layers. A cable may also have additional uninsulated conductors.

[0003] Currently, the tensile strength and abrasion resistance of cable wires are mostly detected by different devices. The cost of the devices is high, which is not conducive to reducing the experimental cost and has low practicability. Therefore, we make improvements and propose a performance detection device for cable wires. Summary of the Invention

One end of the spring is fixedly connected to the end of the limiting cylinder away from the U-shaped limiting member. A limiting rod is arranged in the spring.

[0009] As a preferred technical solution of the present invention, one end of the limiting rod passes through the limiting cylinder and penetrates into the U-shaped limiting member and faces the rotating member. The other end of the spring is fixedly connected to the part of the limiting rod close to the U-shaped limiting member.

Four corners at the bottom end of the seat plate 1 are fixedly provided with support legs 2. In the middle of one side of the top end of the seat plate 1, a first fixing plate 3 is fixedly provided. At the position on the top end of the seat plate 1 that is directly opposite to the first fixing plate 3, a second fixing plate 4 is provided. In the middle of the bottom end of the second fixing plate 4, a dovetail slider 5 is fixedly provided, and a chute matching the dovetail slider 5 is provided on the other side of the top end of the seat plate 1. A scale 6 is provided on one side of the chute. Limiting components 7 for fixing the cable are provided in the middle of the opposite sides of the first fixing plate 3 and the second fixing plate 4. In the middle of the top end of the first fixing plate 3, an electric telescopic rod 8 is fixedly provided. The electric telescopic rod 8 is preferably an LX600 type electric telescopic rod. The end of the piston rod of the electric telescopic rod 8 is fixedly provided with a connecting block 9, and the bottom end of the connecting block 9 is fixedly connected to the middle of the top end of the second fixing plate 4. On both sides of the top of the second fixing plate 4, connecting rods 10 are fixedly provided. On one side of the connecting rod 10, a transmission plate 11 is fixedly provided. A wear-resistant component 12 for detecting the cable is provided between the seat plate 1 and the transmission plate 11. On one side of the seat plate 1, a switch panel 13 is fixedly provided. The electric telescopic rod 8 is electrically connected to an external power supply through a control switch provided on the switch panel 13.

[0023] Among them, the limit component 7 includes a U-shaped limit piece 701. The U-shaped limit pieces 701 of the two limit components 7 are respectively fixedly connected to the first fixed plate 3 and the second fixed plate 4. One side of the bottom end of the U-shaped limit piece 701 is provided with an opening, and a first rotating shaft 702 is fixedly arranged inside the U-shaped limit piece 701; a rotating piece 703 matching the opening is rotatably inserted on the first rotating shaft 702. A limit cylinder 704 is fixedly arranged on one side of the U-shaped limit piece 701 and opposite to the opening. A spring 705 is arranged inside the limit cylinder 704. One end of the spring 705 is fixedly connected to the end of the limit cylinder 704 far from the U-shaped limit piece 701. A limit rod 706 is arranged inside the spring 705; one end of the limit rod 706 passes through the limit cylinder 704 and penetrates into the U-shaped limit piece 701 and is opposite to the rotating piece 703. The other end of the spring 705 is fixedly connected to the part of the limit rod 706 close to the U-shaped limit piece 701. The other end of the limit rod 706 passes through the limit cylinder 704 and is fixedly provided with a pull head. Pull the pull head to make the limit rod 706 move into the limit cylinder 704, and the spring 705 is compressed. Rotate the rotating piece 703 through the first rotating shaft 702, insert one end of the cable into the space between the rotating piece 703 and the U-shaped limit piece 701, rotate the rotating piece 703 to make the rotating piece 703 located inside the opening, so that one end of the cable is stuck between the rotating piece 703 and the U-shaped limit piece 701. Release the pull head, and under the reset action of the spring 705, the limit rod 706 bounces back to its original position, thereby limiting the rotating piece 703, so that one end of the cable is fixed between the rotating piece 703 and the U-shaped limit piece 701. Through this fixing method, the cable can be conveniently fixed between the first fixed plate 3 and the second fixed plate 4.

[0024] Among them, the wear-resistant component 12 includes a wear-resistant part 1201. The bottom end of the wear-resistant part 1201 is fixedly connected to the seat plate 1, and the top end of the wear-resistant part 1201 faces the transmission plate 11. A limiting groove is formed on the wear-resistant part 1201, and the cross-section of the wear-resistant part 1201 is triangular. A grinding column 1202 is arranged at the top of the wear-resistant part 1201; the top end of the grinding column 1202 is in contact with the bottom end of the transmission plate 11. A second rotating shaft 1203 is inserted into the grinding column 1202. Limiting rings 1204 are arranged on both side edges of the grinding column 1202, and the limiting rings 1204 are fixedly inserted with the second rotating shaft 1203. Fixing rods 1205 are fixedly inserted at both ends of the second rotating shaft 1203; the bottom end of the fixing rod 1205 is fixedly connected to the top end of the seat plate 1. U-shaped fixing parts 1206 are arranged on both sides of the wear-resistant part 1201, and both ends of the U-shaped fixing parts 1206 are fixedly connected to the top end of the seat plate 1. A bolt 1207 is threadedly connected to the top end of the U-shaped fixing part 1206, and the bottom end of the bolt 1207 penetrates into the U-shaped fixing part 1206; the bolt 1207 is a hand-tightening bolt. Place the cable on the limiting groove, and both ends of the cable respectively pass through the U-shaped fixing parts 1206. Rotate the bolt 1207 so that the bottom end of the bolt 1207 is in contact with the cable, thereby fixing the cable on the limiting groove and in contact with the bottom end of the grinding column 1202, and the cable is in a straightened state. Turn on the control switch to make the electric telescopic rod 8 work. Through the second rotating shaft 1203 and the limiting rings 1204, in cooperation with the fixing rod 1205, the transmission plate 11 moves back and forth, causing the bottom end of the grinding column 1202 to rotate, and then rubbing against the cable.

[0025] During operation, turning on the control switch enables the electric telescopic rod 8 to work. The piston rod of the electric telescopic rod 8 drives the connecting block 9 to move back and forth along the direction facing the first fixed plate 3. In cooperation with the dovetail slider 5, the second fixed plate 4 moves back and forth. When it is necessary to detect the tensile strength of the cable, pull the pull head, causing the limiting rod 706 to move into the limiting cylinder 704, and the spring 705 to compress. Through the first rotating shaft 702, rotate the rotating member 703. Insert one end of the cable between the rotating member 703 and the U-shaped limiting member 701. Rotate the rotating member 703 so that the rotating member 703 is located within the opening, thereby causing one end of the cable to be stuck between the rotating member 703 and the U-shaped limiting member 701. Release the pull head. Under the reset action of the spring 705, the limiting rod 706 springs back to its original position, thereby limiting the rotating member 703, and thus fixing one end of the cable between the rotating member 703 and the U-shaped limiting member 701. Through this fixing method, the cable can be conveniently fixed between the first fixed plate 3 and the second fixed plate 4. Turn on the control switch to make the electric telescopic rod 8 work. As the electric telescopic rod 8 works, the limiting component 7 on the second fixed plate 4 slowly drives the cable to stretch until the cable starts to break. Stop the electric telescopic rod 8. Through the scale 6, the distance that the second fixed plate 4 moves can be measured. By comparing the distances that the second fixed plate 4 moves caused by different cables, the tensile strengths of different cables can be detected. When it is necessary to test the abrasion resistance of the cable, place the cable on the limiting groove, and both ends of the cable pass through the U-shaped fixing member 1206 respectively. Rotate the bolt 1207 so that the bottom end of the bolt 1207 contacts the cable, thereby fixing the cable on the limiting groove and contacting the bottom end of the grinding column 1202, and the cable is in a straightened state. Turn on the control switch to make the electric telescopic rod 8 work. Through the second rotating shaft 1203 and the limiting ring 1204, in cooperation with the fixed rod 1205, the transmission plate 11 moves back and forth, causing the bottom end of the grinding column 1202 to rotate, and thus rubbing against the cable. By comparing the degrees of friction damage of different cables, the abrasion resistance of the cable can be detected. Through this detection device, an electric telescopic rod 8 can be used to detect the tensile strength and abrasion resistance of the cable, with low manufacturing cost, reduced experimental cost, and improved practicability.
