Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, specifically to a cable laying structure for fire protection engineering. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, such as overhead, underground, underwater, wall-mounted, and tunnel laying. Typically, during cable laying, cable mounting racks are used to install cables onto the walls of cable trenches. However, because the cables are laid directly on the mounting racks, although they can be laid relatively stably under their own weight, they are still unstable. To ensure cable stability, cable ties are usually used to bind the cables to the mounting racks. However, binding each cable individually significantly reduces installation efficiency. Therefore, we propose a cable laying structure for fire protection engineering. Utility Model Content

[0024] Please see Figures 1 to 8A cable laying structure for fire protection engineering includes an installation trench wall 1. An installation frame 2 is bolted to the side wall of the installation trench wall 1. A laying frame 3 is connected to the installation frame 2. Cables are laid on the laying frame 3. A vertically adjustable lifting base block 4 is movably connected to the installation frame 2. The lifting base block 4 can be raised and lowered along a fixed trajectory on the installation frame 2 to adjust its height. The laying frame 3 is fixedly installed on the lifting base block 4, and a clamping assembly 5 is movably connected to the lifting base block 4. The clamping assembly 5 can be raised and lowered along a fixed trajectory on the lifting base block 4. The clamping assembly 5 is located directly above the laying frame 3. Through the clamping of the laying frame 3 and the clamping assembly 5, the cable can be laid... The cables laid on the laying frame 3 are restricted, making their installation more stable. A locking bolt 20 is connected through the laying frame 3 and the holding component 5. One end of the locking bolt 20 passes through the clamping component 5 and is threaded with a nut 24. Under the relative clamping of the locking bolt 20 and the nut 24, the clamping position of the laying frame 3 and the clamping component 5 can be locked to ensure continuous clamping. A limiting plate 22 that can intercept the locking nut 24 is elastically connected to the clamping component 5. The limiting plate 22 can automatically pop out and intercept the nut 24, making it less likely for the nut 24 to deflect, thus making the clamping of the cable more stable.

[0025] Please see Figures 1 to 4 The mounting bracket 2 has a slot 6 on its inner side. The two sides of the lifting base block 4 are movably connected with a plate 7 that can be inserted into the slot 6. The plate 7 can move laterally on the lifting base block 4 along a fixed trajectory. When the plate 7 is inserted into the slot 6, the position of the lifting base block 4 can be locked. The inner end of the plate 7 is fixedly connected with a first spring 18. One end of the first spring 18 is fixed to the lifting base block 4. Under the action of the elastic force of the first spring 18, the plate 7 can automatically extend out of the lifting base block 4 and insert into the slot 6.

[0026] Please see Figures 1 to 4 An unlocking frame 8 is movably connected inside the lifting base block 4. The unlocking frame 8 can move vertically on the lifting base block 4. The top of the unlocking frame 8 extends out of the top of the lifting base block 4, and a cut surface is provided on the top of the inner end of the card plate 7. The two ends of the unlocking frame 8 are provided with inclined surfaces that can cooperate with the cut surface of the card plate 7 to drive the card plate 7 to move into the lifting base block 4. When the unlocking frame 8 is pressed down, it can push the card plate 7 to move into the lifting base block 4 so that the card plate 7 can be unlocked smoothly. A second spring 19 is fixedly connected to the bottom of the middle of the unlocking frame 8. The bottom end of the second spring 19 is fixed to the lifting base block 4. Under the action of the elastic force of the second spring 19, the unlocking frame 8 can automatically return to its original position.

[0027] Please see Figures 1 to 7The cable laying frame 3 includes a cable laying extension plate 11 and a cable laying positioning plate 12. The cable laying extension plate 11 and the cable laying positioning plate 12 are movably connected and can move relative to each other to adjust the width of the cable to be laid. One end of the cable laying positioning plate 12 is fixed to the lifting base block 4. The bottom of one end of the cable laying extension plate 11 is connected to a cable laying sleeve 16 by a shaft pin, so that the cable laying sleeve 16 can rotate relative to the cable laying extension plate 11. One end of the cable laying sleeve 16 is movably sleeved with a cable laying sleeve 17. The cable laying sleeve 17 and the cable laying sleeve 16 can extend and retract relative to each other. With the support of the cable laying sleeve 16 and the cable laying sleeve 17, the balance between the cable laying extension plate 11 and the cable laying positioning plate 12 is more stable. One end of the cable laying sleeve 17 is connected to the lifting base block 4 by a shaft pin, so that the cable laying sleeve 17 can rotate relative to the lifting base block 4.

[0028] Please see Figures 1 to 7 The clamping assembly 5 includes a clamping positioning plate 9 and a clamping extension plate 10. The clamping positioning plate 9 and the clamping extension plate 10 are movably connected and can move relative to each other to adjust the clamping width of the cable. One end of the clamping positioning plate 9 is movably connected to the lifting base block 4, allowing it to move on the lifting base block 4 for easier clamping. The top of one end of the clamping extension plate 10 is connected to a clamping sleeve rod 13 via a pivot pin. This allows the clamping extension plate 10 to rotate relative to the clamping sleeve 13. One end of the clamping sleeve 13 is movably sleeved with a clamping sleeve 14. The clamping sleeve 13 and the clamping sleeve 14 can extend and retract relative to each other. With the support of the clamping sleeve 13 and the clamping sleeve 14, the balance between the clamping positioning plate 9 and the clamping extension plate 10 is more stable. One end of the clamping sleeve 14 is connected to the lifting base block 4 through a shaft pin, allowing the clamping sleeve 14 to rotate relative to the lifting base block 4.

[0029] Please see Figures 1 to 7 Threaded rods 15 are movably mounted in a circular shape on the clamping extension plate 10 and the laying extension plate 11. The threaded rods 15 can rotate in a fixed position on the clamping extension plate 10 and the laying extension plate 11, thereby driving the clamping extension plate 10 and the laying extension plate 11 to move relative to each other. One end of each of the two threaded rods 15 passes through the clamping extension plate 10 to the laying extension plate 11, and the two threaded rods 15 are threadedly connected to the clamping positioning plate 9 and the laying positioning plate 12, respectively. When the threaded rods 15 rotate relative to the clamping positioning plate 9 and the laying positioning plate 12, they can drive the clamping extension plate 10 and the laying extension plate 11 to move and extend.

[0030] Please see Figures 1 to 8The top of the clamping positioning plate 9 is provided with a mounting groove 21. A limiting plate 22 is movably connected to the inner side of the mounting groove 21, with one end extending into the mounting groove 21. A third spring 23 is fixedly connected to the inner side of the end of the limiting plate 22 that extends into the clamping positioning plate 9. One end of the third spring 23 is fixed to the clamping positioning plate 9. Under the action of the elastic force of the third spring 23, the limiting plate 22 can automatically extend to intercept the nut 24.

[0031] In summary, the cable laying structure for this fire protection project, during use, involves pressing the unlocking bracket 8 into the lifting base block 4, which allows the unlocking bracket 8 to push the clamping plate 7 into the lifting base block 4, thus unlocking the clamping plate 7 from the clamping slot 6. Then, the lifting base block 4 is moved to adjust its height. Tightening the threaded rod 15 allows the clamping positioning plate 9 and clamping extension plate 10, as well as the laying extension plate 11 and laying positioning plate 12, to move relative to each other, adjusting the layable width. Finally, the locking bolt 20 is tightened from the laying extension... The bottom end of the extension plate 11 is inserted and installed upwards. Then, the nut 24 is screwed onto the locking bolt 20 and placed in the mounting groove 21. When the nut 24 is installed, the limiting plate 22 is pushed into the clamping positioning plate 9. When the nut 24 is fully installed, the limiting plate 22 can extend under the action of the third spring 23 and lock the nut 24. It can move down to clamp the cable through the clamping positioning plate 9 and the clamping extension plate 10, and can lock the cable by locking the locking bolt 20.
