Description

Technical Field

[0001] This utility model belongs to the field of prefabricated trench technology, and in particular relates to a prefabricated trench for cable routing. Background Technology

[0002] Cable laying is a crucial part of power transmission and communication networks. It involves laying cables safely and efficiently along a predetermined path to ensure the stable transmission of power or signals.

[0003] Precast concrete cable trenches, commonly known as cable trenches or cable troughs, are important facilities used for laying and protecting cables in power and communication systems. A precast concrete cable trench is a concrete structure made of cement, sand, stone, steel bars and other raw materials for laying cables. In power and communication systems, cable trenches are often set up in the cable laying path to ensure the safe and stable operation of cables.

[0004] In practical use, existing prefabricated cable trenches often have support frames installed on both sides of the inner cavity of the trench to facilitate the orderly arrangement of cables. Horizontal plates are placed on these support frames to support the layered cables. However, in actual use, the horizontal plates on both sides of the inner cavity of the prefabricated trench occupy space. When arranging cables on the lower plates, the upper plates are relatively close, creating a spatial obstacle and hindering rapid cable arrangement. Existing devices are not convenient for folding and storing the upper plates when arranging lower cables. Therefore, we propose a prefabricated trench for cable routing. Summary of the Invention

[0005] In view of this, the present invention aims to propose a prefabricated trench for cable routing to solve the technical problem of the inconvenience of folding and storing the upper plate when arranging the lower cable.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A prefabricated trench for cable routing includes a prefabricated trench body. Multiple evenly distributed carrier plates are fixed to both sides of the inner cavity of the prefabricated trench body. A fixed plate is fixed to the lower side of the outer wall of each carrier plate. The trench also includes multiple movable plates, which are hinged to the upper side of the outer wall of each carrier plate via hinge seats. Four stop bars are provided, each stop bar being fixedly connected to the end of one of the two sets of movable plates and one of the two sets of fixed plates.

[0008] It should be understood that when wiring is being carried out inside the precast trench, workers enter the interior of the precast trench and pull the two upper baffles. This causes multiple movable plates to rotate simultaneously, allowing for quick folding and storage of the movable plates. This exposes the lower fixed plates, which helps avoid spatial obstructions when laying cables on the lower side, thus improving wiring efficiency. At the same time, when workers walk inside the precast trench, the baffles shield the ends of the movable and fixed plates, preventing them from scraping or impacting their legs and thus avoiding injury.

[0009] Furthermore, the stop bar is a hollow structure, and a plurality of evenly distributed short shafts are rotatably mounted on one side wall of the stop bar. A limit plate is fixed to the outer end of the short shaft, and the other end of the short shaft movably passes through the side wall of the stop bar and is fixedly connected to a gear. A rack is provided at the bottom of the inner cavity of the stop bar, and the rack meshes with the gear. One end of the rack is connected to a drive assembly.

[0010] Furthermore, the drive assembly includes a movable block, a screw, and a rotating block. The movable block is disposed in the inner cavity of the stop rod, and one end of the movable block is fixedly connected to the rack. The screw movably passes through the end face of the stop rod, and the inner end of the screw is inserted into a threaded hole opened on the end face of the movable block and is threadedly engaged. The rotating block is fixedly connected to the outer end of the screw.

[0011] Furthermore, a matching second rubber pad is fixedly glued to the outer wall of the limiting plate.

[0012] Furthermore, a bearing block is fixedly connected to the bottom of the hinge seat via a connecting plate, and the bearing block is attached to the bottom of the movable plate.

[0013] It should be understood that when the movable plate is rotated to a horizontal position to support the cable, the support block can be used to support the movable plate, thereby ensuring the stability of the movable plate in supporting the cable.

[0014] Furthermore, both the fixed plate and the movable plate have a matching first rubber pad glued to their tops.

[0015] It should be understood that the placement of the first rubber pad helps to prevent wear and tear on the cable when it is under load.

[0016] Furthermore, multiple evenly distributed magnet blocks are fixed on both sides of the inner cavity of the prefabricated trench body.

[0017] It should be understood that the stop bar is a metal structure, which allows the magnet to attract it. When the stop bar is raised to fold and store the movable plate, the outer wall of the stop bar fits against the magnet, thus using the magnet to attract it and stabilize it on the upper side. It can also be quickly pulled down when needed.

[0018] Compared with the prior art, the prefabricated trench for cable routing described in this utility model has the following advantages:

[0019] The prefabricated trench for cable routing described in this utility model is connected by a hinged movable plate on the upper side of a carrier plate. This allows the movable plate on the upper side to be rotated and folded for storage when arranging cables on the lower side, thus avoiding spatial obstruction. Furthermore, pulling the stop bar enables multiple movable plates to be folded and stored quickly and synchronously, further improving operational convenience. The stop bar also provides cover for the ends of the movable and fixed plates, preventing impact on workers' legs during walking and thus reducing the risk of injury.

[0020] The present invention discloses a prefabricated groove for cable routing. The drive assembly can drive the rack to move, thereby driving the gear to rotate, which in turn drives the baffle on one side of the baffle to rotate, so that the baffle rotates to a vertical state. After the cable is laid out, the baffle can limit the cable and help prevent the cable from slipping off the fixed plate and the movable plate. Attached Figure Description

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figure 1-6As shown in the figure, as an embodiment, a prefabricated trench for cable routing includes a prefabricated trench body 1. Multiple evenly distributed carrier plates 2 are fixed to both sides of the inner cavity of the prefabricated trench body 1. A fixed plate 21 is fixed to the lower side of the outer wall of the carrier plate 2. It also includes multiple movable plates 23. The multiple movable plates 23 are hinged to the upper side of the outer wall of the multiple carrier plates 2 via hinge seats 22. The movable plates 23 can be folded and stored. Four stop bars 3 are respectively located at the ends of two sets of movable plates 23 and two sets of fixed plates 21. The four stop bars 3 are fixedly connected to the corresponding ends of the movable plates 23 and fixed plates 21. The stop bars 3 are used to shield the ends of the movable plates 23 and fixed plates 21 to prevent injury to the legs of workers.

[0035] It should be understood that when wiring is being carried out inside the precast trench body 1, workers enter the precast trench body 1 and pull the two upper baffles 3, which simultaneously rotate the corresponding multiple movable plates 23, thereby quickly folding and storing the movable plates 23, exposing the lower fixed plate 21. This helps to avoid spatial obstacles when laying the lower cables first, thus improving wiring efficiency. At the same time, when workers walk inside the precast trench body 1, the baffles 3 can shield the ends of the movable plates 23 and the fixed plate 21, thus preventing the ends of the movable plates 23 and the fixed plate 21 from scraping or impacting the workers' legs, thereby preventing injury to the workers.

[0036] Specifically, multiple evenly distributed magnet blocks 11 are fixed on both sides of the inner cavity of the precast trench body 1. It should be noted that the stop bar 3 is a metal structure, so the magnet blocks 11 can attract it. When the stop bar 3 is raised to fold and store the movable plate 23, the outer wall of the stop bar 3 is attached to the magnet blocks 11, so that the magnet blocks 11 attract it and stabilize it on the upper side. It can also be quickly pulled down when needed.

[0037] Specifically, the bottom of the hinge seat 22 is fixedly connected to the bearing block 24 via a connecting plate, and the bearing block 24 is attached to the bottom of the movable plate 23.

[0038] It should be understood that when the movable plate 23 is rotated to a horizontal position to support the cable, the support block 24 can be used to support the movable plate 23, thereby ensuring the stability of the movable plate 23 in supporting the cable.

[0039] It is worth mentioning that both the fixed plate 21 and the movable plate 23 have a matching first rubber pad glued to their tops. The setting of the first rubber pad helps to avoid wear on the cable when it is bearing the load.

[0040] like Figure 4-6As shown in the embodiment, the stop bar 3 is a hollow structure. Multiple evenly distributed short shafts are rotatably mounted on one side wall of the stop bar 3. The outer end of the short shaft is fixed with a limit plate 31. The other end of the short shaft movably passes through the side wall of the stop bar 3 and is fixedly connected with a gear 33. A rack 32 is provided at the bottom of the inner cavity of the stop bar 3. The rack 32 and the gear 33 mesh. One end of the rack 32 is connected to a drive assembly.

[0041] It should be understood that in actual use, after the cable is placed on top of the fixed plate 21 and the movable plate 23, the drive assembly drives the rack 32 to move, thereby driving the gear 33 to rotate, which in turn drives the short shaft to rotate, thereby indirectly driving the limiting plate 31 to rotate, so that the limiting plate 31 can rotate to a vertical state, thereby limiting the cable after placement, which helps to prevent the cable from slipping off the fixed plate 21 or the movable plate 23. Furthermore, the movement of the rack 32 can drive multiple gears 33 to rotate simultaneously, thereby enabling the rapid operation of multiple limiting plates 31, which helps to improve the convenience of operation.

[0042] Specifically, a matching second rubber pad is glued to the outer wall of the limiting plate 31. The setting of the second rubber pad can prevent wear on the cable when the limiting plate 31 limits the cable.

[0043] Specifically, the drive assembly includes: a movable block 4, which is disposed in the inner cavity of the stop rod 3. One end of the movable block 4 is fixedly connected to the rack 32. A screw 41 movably passes through the end face of the stop rod 3. The inner end of the screw 41 is inserted into a threaded hole opened on the end face of the movable block 4 and is threadedly engaged. The rotating block 42 is fixedly connected to the outer end of the screw 41.

[0044] It should be understood that by rotating the rotating block 42, the screw 41 can be driven to rotate, thereby driving the movable block 4 to move under the thread drive, thus driving the rack 32 to move.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
