Description

Technical Field

[0001] This utility model belongs to the field of cable laying frame technology, specifically relating to a cable laying frame for narrow spaces used in fire protection construction. Background Technology

[0002] In the field of fire protection engineering construction, confined spaces typically refer to areas where personnel access and operational activities are restricted due to spatial dimensions, structural complexity, or environmental limitations. In fire protection construction within confined spaces, cable-laying frames are used for cable laying operations. However, while currently used cable-laying frames possess lateral adjustment capabilities to adapt to space constraints, they exhibit significant compatibility deficiencies in actual operation. The spacing between the two pivots on the core load-bearing structure plate of the cable-laying frame cannot be adjusted, making it difficult to cover application scenarios with a wide range of I-beam cable reels.

[0003] In actual engineering projects, the outer diameter of I-beam reels varies from 400mm to 1600mm, the inner diameter from 150mm to 500mm, and the thickness of the reel body also varies from 50mm to 200mm. When dealing with small reels, because the distance between the rotating shafts cannot be further reduced, the reel will wobble significantly on the support plate, which may cause the reel to tip over due to violent shaking, posing a serious safety hazard. For large reels, the maximum distance between the rotating shafts limits the ability to securely install them on the support plate, causing the pay-off frame to lose its load-bearing function. Utility Model Content

[0004] The purpose of this utility model is to provide a cable laying frame for narrow spaces in fire protection construction, which aims to solve the problem that when facing small cable reels, the distance between the rotating shafts cannot be further reduced, causing the cable reels to shake significantly on the support plate, which may cause the cable reels to tip over due to violent shaking, posing a serious safety hazard; while for large cable reels, the maximum distance between the rotating shafts limits the ability to securely install them on the support plate, causing the cable laying frame to lose its load-bearing function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wiring rack for narrow spaces in fire protection construction, comprising a support plate, two light rods being movably installed between the two support plates, two rotating shafts being installed in the opening of each support plate, a positioning plate being installed at both ends of each rotating shaft, and a sliding strip being connected to one side of each positioning plate;

[0006] The side of the slide bar away from the positioning plate is welded to the inner wall of the pallet. A guide bar is welded to the outer wall on both sides of the open end of the pallet. The bottom of the two pallets is movably connected to the surface of the flat plate. A threaded post is welded to the center end of the flat plate. An insert rod is inserted through the internal thread of the threaded post. When in use, the insert rod is inserted into the ground in the narrow space during fire protection construction.

[0007] To prevent the two pallets from shifting easily when used in narrow spaces during fire protection construction, as a preferred embodiment of this utility model for a wiring rack in narrow spaces for fire protection construction, the bottom of the slide bar is provided with a support bar parallel to it. One side of the support bar is welded to the inner wall of the pallet, and the upper surface of the support bar is in contact with the outer wall below the positioning plate. A rectangular groove is provided at the bottom of the pallet near the horizontal center line, and a flat plate is movably fitted inside the rectangular groove. Side plates are welded to the outer walls of the two pallets on opposite sides, and a fixing bolt is threaded through the top of the side plate.

[0008] The side plate is located above the opening on one side of the rectangular groove. A set of threaded holes adapted to the fixing bolts are equally spaced in the horizontal center line area of ​​the plate. The fixing bolts are threaded through the side plate and locked with the corresponding threaded holes.

[0009] In order to enable the two rotating shafts on the same pallet to be adapted and adjusted according to the size of the I-shaped wire reel, as a wire laying frame for narrow spaces in fire protection construction according to this utility model, preferably, the positioning plate has a sliding groove on the side away from the connection with the rotating shaft, an L-shaped plate is welded to the upper outer wall of the positioning plate, the horizontal part of the L-shaped plate is located above the surface of the guide strip, a T-shaped groove is opened on the surface of the guide strip, and a hexagonal block is installed inside the T-shaped groove;

[0010] The slide groove is slidably installed on the outer wall of the slide bar. A bolt thread extends through the transverse surface of the L-shaped plate into the T-shaped groove, and the bolt is threadedly connected to the hexagonal block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Lay the flat plate horizontally on the ground in the narrow space of the fire protection construction, and then screw the insert rod through the threaded post and tighten it into the ground. Next, fit the rectangular grooves at the bottom of the two support plates into the flat plate surface on both sides of the threaded post, and then pass the fixing bolt through the side plate and align it with the corresponding threaded hole on the flat plate. This will fix the two support plates at the layout point.

[0013] Next, adjust the two rotating shafts on each tray to the center of the tray. As the shafts move, they will move along the outer wall of the corresponding slide bar via the positioning discs on both sides. Stop adjusting when the distance between the two rotating shafts on the same tray matches the size of the corresponding I-shaped wire reel. At this point, insert the bolts through the L-shaped plate and align them with the hexagonal blocks in the T-slot, and tighten the bolts to maintain a locking structure between the hexagonal blocks and the L-shaped plate. Now the I-shaped wire reel can be completely placed between the two trays.

[0014] In summary, when used in confined spaces during fire protection construction, the aforementioned cable-laying device can adapt and adjust the spacing between the two rotating shafts on the same tray according to the size of the I-shaped cable reel, thereby improving the convenience of the overall cable-laying process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6The present invention provides the following technical solution: a wiring rack for narrow spaces in fire protection construction, including a support plate 1, two light rods 2 are movably installed between the two support plates 1, the two support plates 1 can be adjusted laterally by the two light rods 2 to meet the placement requirements of narrow spaces in fire protection construction sites, two rotating shafts 3 are installed in the opening of each support plate 1, a positioning plate 4 is installed at both ends of each rotating shaft 3, and a sliding strip 5 is connected to one side of each positioning plate 4;

[0025] In use, the two trays 1 can be adjusted to both sides along the trajectory of the two guide rods 2 to accommodate the corresponding size of the I-shaped cable reel. During use, place the trays 1 on the ground in a narrow space during fire protection construction, and then place the I-shaped cable reel on the rotating shafts 3 of the two trays 1. Pulling the cable on the I-shaped cable reel causes it to rotate on the two sets of rotating shafts 3, thus facilitating the cable laying operation.

[0026] The side of the slide bar 5 away from the positioning plate 4 is welded to the inner wall of the support plate 1. A guide bar 6 is welded to the outer wall on both sides of the opening end of the support plate 1. The bottom of the two support plates 1 is movably connected to the surface of the flat plate 7. A threaded post 8 is welded to the center end of the flat plate 7. A plug rod 9 is inserted through the internal thread of the threaded post 8. When in use, the plug rod 9 is inserted into the ground in the narrow space during fire protection construction.

[0027] Preferably, a support bar 11 is provided parallel to the bottom of the slide bar 5. One side of the support bar 11 is welded to the inner wall of the support plate 1. The upper surface of the support bar 11 is in contact with the lower outer wall of the positioning disk 4. A rectangular groove 12 is provided at the bottom of the support plate 1 near the horizontal center line. A flat plate 7 is movably fitted inside the rectangular groove 12. Side plates 13 are welded to the outer walls of the two support plates 1 on opposite sides. A fixing bolt 14 is threaded through the top of the side plate 13.

[0028] The side plate 13 is located above the opening on one side of the rectangular groove 12. When the plate 7 is in use, it will be inserted into the rectangular groove 12 at the bottom of the corresponding tray 1. After the rectangular groove 12 and the plate 7 are connected, their bottoms are at the same level, so that the bottom of the tray 1 can be stably placed on the ground.

[0029] The horizontal center line area of ​​the plate 7 is provided with a set of threaded holes that are adapted to the fixing bolt 14 at equal intervals. After the fixing bolt 14 passes through the side plate 13, it is threadedly locked with the corresponding threaded hole.

[0030] After the threaded bolt 14 passes through the side plate 13, it mates with the corresponding threaded hole on the plate 7, thus forming a fixed connection between the side plate 13 and the plate 7. This allows the support plate 1 to be fixed on the plate 7, and in use, the support plate 1 can be fixed to the ground in a narrow space during fire protection construction via the plate 7.

[0031] Preferably, a groove 41 is provided on the side of the positioning disk 4 away from the connection with the rotating shaft 3, and an L-shaped plate 42 is welded to the upper outer wall of the positioning disk 4. The horizontal part of the L-shaped plate 42 is located above the surface of the guide strip 6. A T-shaped groove 61 is provided on the surface of the guide strip 6, and a hexagonal block 62 is installed inside the T-shaped groove 61.

[0032] The slide groove 41 is slidably installed on the outer wall of the slide bar 5. A bolt thread on the surface of the L-shaped plate 42 extends through the transverse surface into the T-shaped groove 61, and the bolt is threadedly connected to the hexagonal block 62.

[0033] In practical use, the outer walls of two sides of the hexagonal block 62 movably abut against the inner walls of the transverse sides of the T-slot 61. When the bolt passes through the L-shaped plate 42 and rotates to engage with the hexagonal block 62, the hexagonal block 62 will be restricted by the T-slot 61 and will not rotate synchronously with the bolt. In this way, the hexagonal block 62 will move upward due to the rotation of the bolt, and thus can cooperate with the L-shaped plate 42 to clamp on the inner and outer sides of the opening of the T-slot 61.

[0034] Working principle: First, lay the plate 7 horizontally on the ground. During laying, ensure the surface is flat, without any obvious tilt or protrusion, to avoid affecting the subsequent installation of the device. Then, take out the insertion rod 9, align it with the center hole of the threaded post 8, and thread the insertion rod 9 through the threaded post 8 until the insertion rod 9 is tightly engaged with the ground, ensuring the plate 7 is stable and does not wobble.

[0035] Next, the rectangular grooves 12 at the bottom of the two support plates 1 are precisely engaged with the surfaces of the flat plates 7 on both sides of the threaded post 8. The dimensions of the rectangular grooves 12 at the bottom of the support plates 1 are adapted to the height of the flat plates 7. After engagement, the fixing bolts 14 are used to pass through the corresponding threaded holes on the side plates 13 and the flat plates 7 in sequence.

[0036] After securing the tray 1, proceed to the adjustment of the rotating shafts 3. Both rotating shafts 3 on each tray 1 are adjustable. During adjustment, hold the rotating shaft 3 and slowly move it along the slide bar 5 towards the center of the tray 1. The positioning discs 4 on both sides of the rotating shaft 3 are made of metal and fit tightly against the outer wall of the slide bar 5, ensuring smooth sliding during movement. Stop adjusting when the distance between the two rotating shafts 3 on the same tray 1 perfectly matches the size of the corresponding I-shaped wire reel. At this point, pass the bolt through the L-shaped plate 42 and precisely align it with the hexagonal block 62 in the T-slot 61. The hexagonal block 62 has anti-slip textures on its surface. Tighten the bolt to form a secure locking structure between the hexagonal block 62 and the L-shaped plate 42, ensuring that the I-shaped wire reel will not wobble or shift after placement and can be stably mounted between the two trays 1.

[0037] In summary, this wire-laying device is designed specifically for the narrow spaces required for fire protection construction. Through the aforementioned operating steps, it can quickly adapt and adjust to confined and complex environments, effectively solving the problems of difficulty and low efficiency in traditional wire-laying methods in narrow spaces, and significantly improving the convenience and efficiency of wire-laying operations.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
