Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray with an anti-fall-off cover. Background Technology

[0002] Cable trays are a key support system for cable laying, building an "aerial corridor" for power and communication lines. They are composed of components such as troughs, brackets, and covers, and are made of various materials. Steel is sturdy, durable, and cost-effective, while aluminum alloy is lightweight and rust-proof, and fiberglass is corrosion-resistant and flame-retardant. Their structure is highly adaptable, and they can be flexibly selected in ladder, trough, and tray types. They can pass through walls, cross beams, and span frames, and are easy to construct and expand. They can also prevent dust and rodents, thus protecting power transmission and communication signals. In existing cable trays, the cover plates are basically slidably installed on the top of the tray. Due to the lack of a fixed structure inside, when laying cables inside, the cables often move inside the tray, causing the cables to push the cover plates off the tray, resulting in inconvenience in installation. Therefore, this utility model proposes a cable tray with an anti-fall-off cover plate to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a cable tray with an anti-detachment cover plate, which solves the problem in the prior art where the cable moves inside the cable tray, causing the cover plate, which is slidably connected to the trough, to detach and making installation inconvenient.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a cable tray with an anti-detachment cover plate, including a trough box, a cover plate and connecting bolts. The top of the trough box is covered with a cover plate, and connecting bolts are symmetrically inserted on both sides of the trough box and the cover plate. Nuts are symmetrically threaded at both ends of the connecting bolts. Hanging rods are symmetrically provided on both sides of the trough box and the cover plate, and an anti-detachment mechanism matching the cover plate is provided on the outer side of the hanging rods.

[0005] A further improvement is made in that: the anti-detachment mechanism includes a first clamping plate, a second clamping plate, and a threaded rod. The first clamping plate is symmetrically arranged on both sides of the cover plate, and the second clamping plate is attached to one side of the first clamping plate. The inner sides of the first clamping plate and the second clamping plate are respectively engaged and connected to the front and back of the cover plate. A circular groove is provided in the middle of the first clamping plate and the second clamping plate. Threaded rods are symmetrically arranged through both sides of the first clamping plate and the second clamping plate, and a set of nuts is symmetrically threaded at both ends of the threaded rod.

[0006] A further improvement is that the inner wall of the circular groove fits against the outer wall of the hanging rod, and a set of assembly plates are symmetrically fixedly connected to both sides of the groove box. The bottom ends of the first clamping plate and the second clamping plate are detachably connected to the set of assembly plates by assembly bolts.

[0007] A further improvement is that: a locking block is symmetrically fixedly connected to one side of the second clamping plate, and a locking groove is symmetrically provided on one side of the first clamping plate, with the outer wall of the locking block engaging with the inner wall of the locking groove.

[0008] A further improvement is that a stop block is fixedly connected to the bottom end of the boom, and through holes matching the boom are symmetrically provided on both sides of the slot box and the cover plate. A pressure cap is threadedly connected to the outer wall of the boom.

[0009] A further improvement is that both the slot box and the cover plate are made of steel plates, and both the surface of the slot box and the cover plate are provided with a galvanized layer. Limiting components are symmetrically provided on both sides of the slot box.

[0010] A further improvement is that the limiting component includes a movable block, a positioning block, an arc groove, and a locking bolt. The movable block covers the top of the positioning block, and the movable block and the positioning block are symmetrically provided with arc grooves on both sides. The positioning block is internally threaded with a locking bolt, and the top of the locking bolt is fitted and connected to the top of the movable block.

[0011] The beneficial effects of this utility model are as follows: A set of No. 1 clamp plate and No. 2 clamp plate are placed on both sides of a lifting rod, and the circular grooves inside the set of No. 1 clamp plate and No. 2 clamp plate are fitted with the outer wall of the lifting rod. The No. 1 clamp plate and No. 2 clamp plate are fixed to the mounting plate on the slot box by mounting bolts, locking the position of the No. 1 clamp plate and No. 2 clamp plate. At this time, the inner side of the No. 1 clamp plate and No. 2 clamp plate clamps the outer wall of the cover plate, generating resistance when the cable pushes the cover plate, preventing the cover plate from suddenly falling off the top of the slot box.

Detailed Implementation

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a cable tray with an anti-detachment cover plate, including a trough box 1, a cover plate 2, and connecting bolts 3. The top of the trough box 1 is covered by the cover plate 2. Connecting bolts 3 are symmetrically inserted on both sides of the trough box 1 and the cover plate 2. Nuts are symmetrically threaded to both ends of the connecting bolts 3. Hanging rods 10 are symmetrically provided on both sides of the trough box 1 and the cover plate 2. An anti-detachment mechanism matching the cover plate 2 is provided on the outer side of the hanging rods 10. When using this cable tray, the cable is first arranged inside the trough box 1, then the cover plate 2 is placed on the top of the trough box 1, and connecting bolts 3 are inserted into both sides of the trough box 1 and the cover plate 2 respectively. Then, nuts are tightened on both ends of the connecting bolts 3. The two sets of nuts clamp the sides of the trough box 1 and the cover plate 2 respectively, so as to connect the cover plate 2 and the trough box 1 into a whole, forming a complete cable tray. The anti-detachment mechanism can clamp the cover plate 2, so that when the cable pushes the cover plate 2, resistance is generated, preventing the cover plate 2 from suddenly falling off the top of the trough box 1.

[0016] The anti-detachment mechanism includes a first clamping plate 5, a second clamping plate 6, and a threaded rod 9. The first clamping plate 5 is symmetrically arranged on both sides of the cover plate 2. The second clamping plate 6 is attached to one side of the first clamping plate 5. The inner sides of the first clamping plate 5 and the second clamping plate 6 are respectively engaged with the front and back of the cover plate 2. A circular groove 11 is provided in the middle of both the first clamping plate 5 and the second clamping plate 6. A threaded rod 9 is symmetrically threaded through both sides of the first clamping plate 5 and the second clamping plate 6. A set of nuts is symmetrically threaded to both ends of the threaded rod 9. The inner wall of the circular groove 11 is attached to the outer wall of the hanging rod 10. A set of assembly plates 4 are symmetrically fixedly connected to both sides of the slot box 1. The bottom ends of the first clamping plate 5 and the second clamping plate 6 are detachably connected to the set of assembly plates 4 by assembly bolts. A set of first clamping plates 5 and the second clamping plate 6 are placed on both sides of a hanging rod 10, and the circular grooves inside the set of first clamping plates 5 and the second clamping plate 6 are respectively engaged with the outer wall of the hanging rod 10. The outer wall of the slot 11 is fitted with the outer wall of the hanging rod 10. The first clamp plate 5 and the second clamp plate 6 are fixed to the mounting plate 4 on the slot box 1 by the mounting bolts, locking the position of the first clamp plate 5 and the second clamp plate 6. At this time, the inner side of the first clamp plate 5 and the second clamp plate 6 clamps the outer wall of the cover plate 2, generating resistance when the cable pushes the cover plate 2, preventing the cover plate 2 from suddenly falling off the top of the slot box 1. Before connecting the two sets of first clamp plates 5 and second clamp plates 6 to the mounting plate 4, two sets of nuts are screwed into the two ends of the two threaded rods 9 respectively. Then, the two ends of the two threaded rods 9 are passed through from both sides of the two sets of first clamp plates 5 and second clamp plates 6 respectively. Finally, the nuts are tightened at the through ends, and the first clamp plate 5 and the second clamp plate 6 are clamped by the two sets of nuts respectively. In this way, the two sets of first clamp plates 5 and second clamp plates 6 can be connected into one body by the two threaded rods 9, making the structure of the anti-detachment mechanism more stable.

[0017] A locking block 7 is symmetrically fixedly connected to one side of the second clamping plate 6, and a locking groove 8 is symmetrically provided on one side of the first clamping plate 5. The outer wall of the locking block 7 is engaged with the inner wall of the locking groove 8. After the first clamping plate 5 and the second clamping plate 6 are attached, the locking block 7 is inserted into the inside of the locking groove 8. The locking block 7 and the locking groove 8 play a guiding role for the first clamping plate 5 and the second clamping plate 6, and position and assemble the first clamping plate 5, the second clamping plate 6 and the hanging rod 10.

[0018] The bottom end of the hanger 10 is fixedly connected to a stop block. The two sides of the trough box 1 and the cover plate 2 are symmetrically provided with through holes that match the hanger 10. The outer wall of the hanger 10 is threaded with a pressure cap. The hanger 10 is inserted into the through holes of the trough box 1 and the cover plate 2 from bottom to top until the stop block at the bottom of the hanger 10 fits against the bottom of the trough box 1. The pressure cap is screwed into the outside of the hanger 10 from top to bottom. After the pressure cap fits against the top of the cover plate 2, it cooperates with the stop block to clamp the cover plate 2 and the trough box 1, fixing the hanger 10 and the cable tray into one piece. Then the hanger 10 is fixed to the ceiling of the room to suspend the cable tray on the ceiling of the room.

[0019] Both the trough 1 and the cover plate 2 are made of steel plates, and both the surface of the trough 1 and the cover plate 2 are coated with a galvanized layer. The two sides of the trough 1 are symmetrically equipped with limiting components 12. The steel plate is immersed in molten zinc liquid, so that a zinc layer is attached to its surface. The hot-dip galvanized layer is thick, firmly bonded, and has good corrosion resistance and wear resistance, which can effectively extend the service life of the cable tray.

[0020] The limiting component 12 includes a movable block 13, a positioning block 14, an arc-shaped groove 15, and a locking bolt 16. The movable block 13 covers the top of the positioning block 14. Arc-shaped grooves 15 are symmetrically provided on both sides of the movable block 13 and the positioning block 14. The locking bolt 16 is threadedly connected to the inside of the positioning block 14. The top end of the locking bolt 16 is fitted and connected to the top of the movable block 13. The bottom end of the locking bolt 16 is unscrewed out of the interior of the positioning block 14. The locking bolt 16 and the movable block 13 are removed together from the top of the positioning block 14. The cable is clamped into the arc-shaped groove 15 of the positioning block 14. The movable block 13 is then covered on the top of the positioning block 14. The bottom end of the locking bolt 16 is screwed into the interior of the positioning block 14. The locking bolt 16 moves downward, causing the movable block 13 and the positioning block 14 to close together and clamp the cable, thereby limiting the cable and arranging it neatly inside the slot box 1.

[0021] The cable tray has a set of clamp plates 5 and 6 placed on both sides of a hanger 10. The circular grooves 11 inside the clamp plates 5 and 6 fit against the outer wall of the hanger 10. The clamp plates 5 and 6 are fixed to the mounting plate 4 on the tray box 1 by mounting bolts, locking the position of the clamp plates 5 and 6. At this time, the inner side of the clamp plates 5 and 6 clamps the outer wall of the cover plate 2, generating resistance when the cable pushes the cover plate 2, preventing the cover plate 2 from suddenly falling off the top of the tray box 1.
