Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a fire-fighting cable tray with fireproof function. Background Technology

[0002] Fire-fighting cable trays are support structures specifically designed for laying electrical wiring in fire protection systems. They are used to support and protect electrical transmission media such as wires and cables. During a fire, they ensure the normal operation of critical fire-fighting equipment such as alarm systems, fire extinguishing devices, and emergency lighting, thereby guaranteeing the safe evacuation of personnel and the smooth progress of fire-fighting and rescue operations.

[0003] Chinese invention patent application CN218124187U discloses a high-temperature resistant fire-fighting cable tray. This patent addresses the problems of existing cable trays where cables are easily damaged by vibrations caused by the magnetic effect of current, and are also susceptible to damage from high temperatures during fires. Furthermore, the top cover is inconvenient for daily use and cannot meet operational needs. The proposed solution includes a cable tray housing and a cover plate. The cover plate is located on the top of the cable tray housing. A cavity is formed in the cable tray housing, and a heat insulation layer is installed within the cavity. Multiple limiting and damping mechanisms are installed inside the cable tray housing. This invention effectively buffers the vibration force generated by the cables. The heat insulation layer effectively reduces the impact of high temperatures on the cables during a fire. Simultaneously, the top cover can be removed for inspection and maintenance of the internal cables, effectively improving maintenance efficiency.

[0004] In existing technology, fire-fighting cable trays directly suspend cables high indoors using hooks, leaving the cables exposed to the air. If a fire or other emergency occurs indoors, the unprotected cables could be directly ignited, causing damage to the wiring. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fire-resistant cable tray with fireproof function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire-resistant cable tray for fire protection includes fire-resistant cables and further includes:

[0008] The outer box assembly includes an outer box, the top of which has a slot, and the bottom of which is fitted with a sliding box. The inside of the sliding box has a sliding groove, and a sliding plate is slidably mounted inside the sliding groove. One side of the outer box has a slot.

[0009] Further technical solutions also include: landing gear assembly, which includes a cantilever frame erected outside the fire cable, a mounting plate installed on one side of the cantilever frame, bolts around the perimeter of the mounting plate, a rod on one side of the mounting plate, a top plate on one side of the rod, and a cylinder on one side of the top plate.

[0010] A further technical solution involves providing side plates on both sides of the cylinder, with screws on the surface of the side plates.

[0011] A further technical solution is to ensure that the width of the slot is consistent with the bottom side arm of the outer box, and the width of the slot is consistent with the width of the rod.

[0012] A further technical solution involves an "N"-shaped cantilever structure, with the end structure of the cantilever made of elastic fireproof material.

[0013] A further technical solution involves slotting the two end faces of the outer box, through which the fire protection cable passes.

[0014] A further technical solution involves fixing the outer box assembly to the wall surface using brackets and threaded connectors, ensuring the outer box assembly remains horizontal.

[0015] Compared with the prior art, this utility model provides a fire-resistant cable tray for fire protection, which has the following advantages:

[0016] The landing gear assembly uses cylinders to control the up-and-down movement of the cables on the entire cantilever frame. After the cables are suspended, the cylinders indirectly control the cantilever frame on the mounting plate to rise via rods, thereby retracting the cables into the outer casing. Once retracted, a sliding plate is inserted into the groove to achieve a seal, directly preventing damage to the internal wiring. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1 - Figure 4 A fire-resistant cable tray for fire protection, comprising a fire-resistant cable 1, and further comprising:

[0024] The outer box assembly 3 includes an outer box 9, which is a storage and support component. The top of the outer box 9 is provided with a groove 15, which is used to ensure that the rod 7 and the top plate 14 are positioned and slid within it. The bottom of the outer box 9 is connected to a sliding box 10, and the sliding groove 11 inside the sliding box 10 is the part where the sliding plate 13 slides. The sliding groove 11 is provided inside the sliding box 10, and the sliding plate 13 is slidably arranged inside the sliding groove 11. A slot 12 is provided on one side of the outer box 9 to provide a passage for the cantilever 4 to descend.

[0025] A fire-resistant cable tray for fire protection further includes: a lifting frame assembly 2, the lifting frame assembly 2 including a cantilever frame 4 erected on the outside of the fire-resistant cable 1, the cantilever frame 4 directly suspending the fire-resistant cable 1; a mounting plate 5 is installed on one side of the cantilever frame 4, bolts 6 are provided around the perimeter of the mounting plate 5, a rod 7 is provided on one side of the mounting plate 5, a top plate 14 is provided on one side of the rod 7, and a cylinder 8 is provided on one side of the top plate 14, the cylinder 8 controlling the up and down movement of the hook of the cantilever frame 4 through the top plate 14 and the rod 7.

[0026] A fire-resistant cable tray for fire protection has side plates 16 on both sides of a cylinder 8, and screws 17 are provided on the surface of the side plates 16. The side plates 16 and screws 17 are components for fixing the cylinder 8 to the side of the outer box 9.

[0027] A fire-resistant cable tray with fireproof function has a slot 12 with a width consistent with the bottom side arm of the outer box 9 to ensure the passage of the cable tray 4; and a slot 15 with a width consistent with the width of the rod 7 to ensure the passage of the rod 7 and the top plate 14.

[0028] A fire-resistant cable tray with fireproof function, wherein the cantilever 4 has an "N" shaped structure and the end structure of the cantilever 4 is made of elastic fireproof material for suspending cables.

[0029] A fire-resistant cable tray with fireproof function has grooves on both ends of the outer box 9, through which the fire-resistant cable 1 passes to guide the cable.

[0030] A fire-resistant cable tray for fire protection, wherein the outer box assembly 3 is fixedly installed on the wall surface by means of brackets and threaded connectors. The outer box assembly 3 is kept horizontal to prevent the device from tipping over.

[0031] Working principle:

[0032] In the actual design process, this utility model addresses the following defects in the prior art: "In the prior art, fire-fighting cable trays directly use hooks to suspend cables at a high point indoors, while the cables themselves are exposed to the air. If a fire or other emergency occurs indoors, the unprotected cables may be directly ignited, leading to line damage." Therefore, the landing gear assembly 2 and the outer box assembly 3 are specifically proposed.

[0033] Outer box component 3:

[0034] The outer casing assembly 3 is the external protective structure and storage component of this device. The hollow structure in the middle of the outer casing 9 is where the cable 1 is directly placed. The cable 1 is suspended and routed via the cantilever bracket 4. The cantilever bracket 4 is directly connected to the output end of the cylinder 8 via the rod 7 and the top plate 14. The cylinder 8 pulls the cable 1 from inside the slot 12 back into the outer casing 9 by pulling it up and down. Once pulled back, the slide plate 13 is slid into the slide groove 11 so that the slide plate 13 completely covers the bottom of the slide box 10, sealing the bottom of the slide box 10 and protecting the cable.

[0035] This invention solves the problem in the prior art where the cable 1 is directly suspended on the surface of the cantilever 4, which easily leads to exposure and makes it impossible to avoid fire damage, and greatly protects the cable 1.

[0036] This invention utilizes a lifting frame assembly and a cylinder to control the vertical movement of the cables on the entire cantilever frame. After the cables are suspended, the cylinder indirectly controls the cantilever frame on the mounting plate to rise via a rod, thereby retracting the cables into the outer box. Once retracted, a sliding plate is inserted into the sliding groove to achieve a sealing effect, directly preventing damage to the internal wiring. Furthermore, since the cables are directly stored inside the protective outer box 9, the rigid structure of the outer box 9 also provides physical protection for the cables, preventing damage from external impacts.
