[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1: like Figures 1 to 9 As shown, an assembled wire and cable installation device for a box-type substation according to an embodiment of the present invention comprises an electrical component body 1, a mounting frame 2 and a clamping structure 33. The mounting frame 2 is fixedly installed in the box-type substation, and the electrical component body 1 is fixedly installed on the surface of the mounting frame 2 to carry the positioning mechanism 32 and the electrical component body 1.

The surface of the bracket 6 is provided with an empty groove 7. The surface of the rotating shaft 36 in the auxiliary roller 8 is sleeved with a bearing 25. The bearing 25 is arranged in the empty groove 7 and is slidably connected through a spring 27. A fixed shaft 15, the fixed shaft 15 is rotatably connected in the bracket 6 via a ratchet mechanism 35; Elastic rope 5, the elastic rope 5 is fixedly connected to the outer ring of the bearing 25 on the surface of the auxiliary roller 8, and the other end of the elastic rope 5 passes through the side wall of the empty groove 7 and is fixed on the fixed shaft 15; A guide wire 4 is arranged between the main roller 9 and the auxiliary roller 8, and a "V"-shaped groove is provided on the surface of the main roller 9 and the auxiliary roller 8.

[0022] During operation, the mounting frame 2 is first mounted in the box-type substation, and then the bracket 6 is mounted on the surface of the slide rail 3 through the fixing structure 34, and then the conductor 4 is mounted between the main roller 9 and the auxiliary roller 8, and then the fixing shaft 15 is twisted, at this time the fixing shaft 15 pulls the elastic rope 5 to reel, and at this time the elastic rope 5 will pull the auxiliary roller 8 to move in the direction close to the main roller 9, and at the same time squeeze the spring to generate elastic force, when the fixing shaft 15 rotates, the fixing shaft 15 is positioned by the ratchet mechanism 35, and the elastic rope 5 can cooperate with the ratchet mechanism 35 to clamp the conductor 4 more stably, and the ratchet mechanism 35 can prevent the fixing shaft 15 from reversing, causing the elastic rope 5 to reset, and then after the outer skin of the conductor 4 is peeled off, the bracket 6 is moved up and down, so that the main roller 9 and the auxiliary roller 8 on the surface of the bracket 6 clamp and drive the conductor 4 to move up and down, so that the conductor 4 can be installed on the electrical component body 1, and then the conductor 4 is installed by tightening the fixing bolts on the surface of the electrical component body 1, and the conductor 4 can be slid upward or downward by the main roller 9 and the auxiliary roller 8. , and the optimal length of the wire 4 can be installed on the electrical component body 1. Then, after the wire 4 is fixed, the main roller 9 and the auxiliary roller 8 are positioned by the bracket 6, and the wire 4 is fixed by the main roller 9 and the auxiliary roller 8 to prevent the wire 4 from vibrating and then loosening, thereby avoiding the possibility of false connection, heating, and even fire. At the same time, positioning can assist the staff in installation, greatly saving the staff's physical strength, thereby improving the installation efficiency. The "V"-shaped grooves opened on the surfaces of the main roller 9 and the auxiliary roller 8 can adapt to wires 4 of different diameters, and at the same time, the stability after fixation can be further increased to avoid left and right shaking. Through the opening under the slide rail 3, the positioning mechanism 32 can also be removed as needed to facilitate the installation of the wire 4 at other positions. The main roller 9 cooperates with the rotation of the auxiliary roller 8 to adjust the length of the wire 4, further improving the convenience of the installation of the wire 4. The rotating connected main roller 9 and auxiliary roller 8 can avoid scratching the outer skin of the wire 4.

[0023] The fixed structure 34 includes an inner cavity 31, which is opened inside the bracket 6. The bracket 6 is "L"-shaped. The short arm end of the bracket 6 is slidably connected to the surface of the slide rail 3. A slider 13 is arranged in the inner cavity 31. The end of the slider 13 passes through the inner cavity 31 for sliding connection, and the end is fixedly connected with a pressure block 14. The surface of the bracket 6 is slidably connected with a card block 10 through a spring 28. The other end of the card block 10 is fixedly connected with a steel wire rope 12. The end of the steel wire rope 12 away from the card block 10 passes through the inner cavity 31 and is fixedly connected with the slider 13. Two card blocks 10 are arranged. The surface of the slide rail 3 is provided with a plurality of card slots 11 relative to the position of the card block 10, and the surface of the card block 10 is provided with an oblique angle; During operation, when the wire 4 needs to be removed, the two pressing blocks 14 are squeezed in the direction of approaching each other, so that the pressing block 14 will drive the slider 13 to move, so that the slider 13 drives the wire rope 12 to move, so that the wire rope 12 pulls the two clamping blocks 10 to move in the direction of approaching each other, so that the clamping block 10 is separated from the clamping slot 11. At this time, the bracket 6 is slid downward, and then the bracket 6 can be slid in the direction away from the electrical component body 1, and the wire 4 can also be driven to separate from the electrical component body 1. Through the clamping block 10 and the clamping slot 11, the bracket 6 and the wire 4 can be quickly removed and installed, and it is also convenient to quickly adjust the height of the wire 4. Through the oblique angle of the surface of the clamping block 10, when the wire 4 is installed, the bracket 6 can be directly slid in the direction close to the electrical component body 1, and at the same time, the clamping block 10 will be driven to move, so that the oblique angle of the surface of the clamping block 10 squeezes the clamping slot 11, and then driven by the spring, the clamping block 10 is clamped into the next clamping slot 11 for rapid positioning.

[0024] A clamping structure is provided in the main roller 9, and the clamping structure includes a threaded shaft 16, a collar 161 and a support shaft 17. The main roller 9 is hollow in design. The threaded shaft 16 is arranged in the main roller 9, and the end of the threaded shaft 16 passes through the main roller 9 for rotation connection. A through hole 23 is provided on the surface of the main roller 9, and a push plate 22 is rotatably connected in the through hole 23. The threaded shaft 16 pushes the push plate 22 to rotate through the collar 161 and the support shaft 17. The surface of the threaded shaft 16 is rotatably connected with the collar 161 through a thread, and the surface of the collar 161 is rotatably connected with the support shaft 17. One end of the support shaft 17 away from the collar 161 is movably mounted on the surface of the push plate 22. The surface of the bracket 6 is slidably connected with a knob 18 through a spring four 30. The surface of the knob 18 is fixedly connected with a limiting shaft 19, and a plurality of limiting shafts 19 are provided. A limiting hole 191 is provided at the end of the threaded shaft 16 passing through the main roller 9. During operation, two rings 161 are provided, and are symmetrically designed. The threads on the surface of the threaded shaft 16 are designed in forward and reverse directions. After the main roller 9 cooperates with the auxiliary roller 8 to clamp the wire 4, the knob 18 is pressed in the direction close to the main roller 9, so that the knob 18 drives the limiting shaft 19 to be stuck in the limiting hole 191, and then the knob 18 is rotated, so that the knob 18 drives the threaded shaft 16 to rotate. At this time, the two rings 161 move in the direction close to each other under the drive of the threads, and at the same time drive the support shaft 17 to move. At this time, the support shaft 17 drives the push plate 22 to rotate in the through hole 23, so that the push plate 22 is stretched outward and fits on the surface of the wire 4 to clamp the wire 4, thereby preventing the main roller 9 and the auxiliary roller 8 from rotating, thereby ensuring the fixing effect of the wire 4.

[0025] The support shaft 17 is divided into a main rod 20 and a secondary rod 21. The main rod 20 is slidably connected in the secondary rod 21 through a spring 29. The end of the main rod 20 is rotatably connected to the collar 161. The end of the secondary rod 21 is movably connected to a push plate 22. There are multiple push plates 22, which are equidistantly distributed. A rubber pad 26 is provided on the surface of the push plate 22. During operation, after the push plate 22 closest to the conductor 4 is attached to the surface of the conductor 4, the threaded shaft 16 continues to rotate, and the push plate 22 that first contacts the conductor 4 squeezes the secondary rod 21 and the main rod 20 to contract. At this time, the collar 161 continues to move, thereby driving the other support shafts 17 to move, so that the push plates 22 at a position farther from the conductor 4 are also attached to the surface of the conductor 4. Through the telescopic support shaft 17, multiple push plates 22 can be attached to the surface of the conductor 4 at the same time, thereby further improving the main roller 9 and the secondary roller 8. The rubber pad 26 designed on the surface of the push plate 22 can prevent the push plate 22 from crushing the wire 4. When the push plate 22 closer to the wire 4 is in contact with the surface of the wire 4, the threaded shaft 16 continues to rotate, so that the support shaft 17 drives the other push plates 22 to continue to move. At this time, the push plate 22 that has been in contact with the surface of the wire 4 will squeeze the auxiliary rod 21 to retract into the main rod 20. Through the design of the retractable support shaft 17, the other push plates 22 can also be in contact with the surface of the wire 4, thereby improving the fixing effect of the wire 4.

[0026] Embodiment 2: like Fig.10 As shown, compared with Example 1, another implementation of the present invention is: an anti-skid pad 24 is fixedly connected to the surface of the pressing block 14, the anti-skid pad 24 is made of rubber, and has anti-skid grooves on the surface; when working, the anti-skid pad 24 on the surface of the pressing block 14 can increase the friction of the staff's hands to avoid slipping, thereby improving the convenience of removing the bracket 6.

[0027] Working principle: first install the mounting frame 2 in the box-type substation, then install the bracket 6 on the surface of the slide rail 3 through the positioning mechanism 32, then install the conductor 4 between the main roller 9 and the auxiliary roller 8, and then twist the fixed shaft 15. At this time, the fixed shaft 15 pulls the elastic rope 5 to reel up. At this time, the elastic rope 5 will pull the auxiliary roller 8 to move in the direction close to the main roller 9, and at the same time squeeze the spring to generate elastic force. When the fixed shaft 15 rotates, the fixed shaft 15 will be positioned by the ratchet mechanism 35. The elastic rope 5 can cooperate with the ratchet mechanism 35 to clamp the conductor 4 more stably. The ratchet mechanism 35 can prevent the fixed shaft 15 from reversing, causing the elastic rope 5 to reset. Then, after the outer skin of the conductor 4 is peeled off, the bracket 6 is moved up and down, so that the main roller 9 and the auxiliary roller 8 on the surface of the bracket 6 clamp and drive the conductor 4 to move up and down, so that the conductor 4 can be installed on the electrical component body 1, and then the conductor 4 is installed by tightening the fixing bolts on the surface of the electrical component body 1. The conductor 4 can be slid up or down by the main roller 9 and the auxiliary roller 8. Therefore, the optimal length of the wire 4 can be installed on the electrical component body 1. Then, after the wire 4 is fixed, the main roller 9 and the auxiliary roller 8 are positioned by the positioning mechanism 32. The wire 4 is fixed by the main roller 9 and the auxiliary roller 8 to prevent the wire 4 from loosening due to vibration, thereby avoiding the possibility of false connection, heating, and even fire. At the same time, the positioning can assist the staff in installation, greatly saving the staff's physical strength, thereby improving the installation efficiency. The "V"-shaped grooves opened on the surfaces of the main roller 9 and the auxiliary roller 8 can adapt to wires 4 of different diameters, and at the same time, the stability after fixation can be further increased to avoid left and right shaking. The positioning mechanism 32 can also be removed according to the situation through the opening under the slide rail 3 to facilitate the installation of the wire 4 at other positions. The main roller 9 cooperates with the rotation of the auxiliary roller 8 to adjust the length of the wire 4, further improving the convenience of the installation of the wire 4. The rotating connected main roller 9 and auxiliary roller 8 can avoid scratching the outer skin of the wire 4. When the wire 4 needs to be removed, the two pressing blocks 14 are squeezed in the direction of approaching each other, so that the pressing block 14 will drive the slider 13 to move, so that the slider 13 drives the wire rope 12 to move, so that the wire rope 12 pulls the two clamping blocks 10 to move in the direction of approaching each other, so that the clamping block 10 is separated from the clamping slot 11, and then the bracket 6 is slid downward, and then the positioning mechanism 32 can be slid in the direction away from the electrical component body 1, and the wire 4 can also be driven to separate from the electrical component body 1. Through the clamping block 10 and the clamping slot 11, the positioning mechanism 32 and the wire 4 can be quickly removed and installed, and it is also convenient to quickly adjust the height of the wire 4. Through the oblique angle of the surface of the clamping block 10, when the wire 4 is installed, the bracket 6 can be directly slid in the direction close to the electrical component body 1, and at the same time, the clamping block 10 will be driven to move, so that the oblique angle of the surface of the clamping block 10 squeezes the clamping slot 11, and then driven by the spring, the clamping block 10 is clamped into the next clamping slot 11 for rapid positioning; There are two rings 161, and they are symmetrically designed. The threads on the surface of the threaded shaft 16 are designed in forward and reverse directions. After the main roller 9 cooperates with the auxiliary roller 8 to clamp the wire 4, the knob 18 is pressed in the direction close to the main roller 9, so that the knob 18 drives the limiting shaft 19 to fit into the limiting hole 191, and then the knob 18 is rotated, so that the knob 18 drives the threaded shaft 16 to rotate. At this time, the two rings 161 move in the direction close to each other under the drive of the threads, and at the same time drive the support shaft 17 to move. At this time, the support shaft 17 drives the push plate 22 to rotate in the through hole 23, so that the push plate 22 is stretched outward and fits on the surface of the wire 4 to clamp the wire 4, thereby preventing the main roller 9 and the auxiliary roller 8 from rotating, thereby ensuring the fixing effect of the wire 4. After the push plate 22 closest to the wire 4 fits on the surface of the wire 4, the threaded shaft 16 continues to be rotated. At this time, the push plate 22 that first contacts the wire 4 will squeeze The secondary rod 21 and the main rod 20 are compressed, and the collar 161 continues to move, thereby driving the other support shafts 17 to move, so that the push plates 22 at a position farther from the wire 4 also fit on the surface of the wire 4. Through the telescopic support shaft 17, multiple push plates 22 can be simultaneously fitted on the surface of the wire 4, thereby further improving the clamping effect of the main roller 9 and the secondary roller 8. The rubber pad 26 designed on the surface of the push plate 22 can prevent the push plate 22 from crushing the wire 4. When the push plate 22 closer to the wire 4 fits on the surface of the wire 4, the threaded shaft 16 continues to rotate, so that the support shaft 17 drives the other push plates 22 to continue to move. At this time, the push plate 22 that has been fitted on the surface of the wire 4 will squeeze the secondary rod 21 to retract into the main rod 20. Through the design of the telescopic support shaft 17, other push plates 22 can also fit on the surface of the wire 4, thereby improving the fixing effect on the wire 4. The anti-skid pad 24 on the surface of the pressing block 14 can increase the friction of the worker's hands to avoid slipping, thereby improving the convenience of removing the bracket 6.
