[0001] This utility model relates to the field of power equipment technology, specifically a tray-type fireproof cable tray. Background Technology

[0002] Tray-type fireproof cable trays are cable laying devices that combine the structural advantages of tray-type cable trays with fireproof functions. They are widely used in places with high fire safety requirements, such as high-temperature environments, fire lanes, areas prone to fire, as well as in the fields of power, communications, petrochemicals, and construction.

[0003] In the prior art, patent CN218242856U discloses a tray-type fireproof and heat-dissipating cable tray, including a cable tray body. The bottom of the cable tray body has an installation groove that runs through both ends of the cable tray body. Support plates are provided on the inner walls of both sides of the cable tray body near the installation groove. The upper part of the support plate has a track groove.

[0004] This type of tray-type fireproof and heat dissipation cable tray has some problems. For example, the upper and lower fireproof baffles are only connected by plugging, which affects the stability of the connection between the two fireproof baffles. In addition, the fixed installation unit cannot effectively adapt to different installation environments, affecting the stability and convenience of the cable tray. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a tray-type fireproof cable tray. The position of the mounting cylinder can be adjusted by rotating the mounting handle, thereby meeting the installation requirements in different working environments. At the same time, the connection mechanism improves the connection stability between the lower fireproof baffle and the adjacent upper fireproof baffle, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tray-type fireproof cable tray, including a lower fireproof baffle, with an upper fireproof baffle slidably connected to the upper end of the lower fireproof baffle, and also including an installation mechanism and a connection mechanism;

[0007] Installation mechanism: It includes a gathering groove, a limiting post, an adjusting cylinder and an installation handle. The gathering grooves are symmetrically arranged at the left and right ends of the lower fireproof baffle. The middle of each gathering groove is fixedly connected to a limiting post. The outer surface of each limiting post is slidably connected to the inner arc surface of the adjacent adjusting cylinder. The end of the outer arc surface of the adjusting cylinder away from the center of the lower fireproof baffle is rotatably connected to an installation handle.

[0008] Connection mechanism: It is set between the lower fireproof baffle and the adjacent upper fireproof baffle. The position of the mounting cylinder is adjusted by rotating the mounting handle, so as to meet the installation requirements in different working environments. At the same time, the connection mechanism improves the connection stability between the lower fireproof baffle and the adjacent upper fireproof baffle.

[0009] Furthermore, the installation mechanism also includes a limiting groove and a limiting rod. The limiting grooves are all located in the middle of the limiting column, and the inner arc surface of the adjusting cylinder is fixedly connected to the limiting rod. The limiting rod is slidably connected to the adjacent limiting groove to provide guidance and limitation for the sliding of the adjusting cylinder.

[0010] Furthermore, the installation mechanism also includes installation cylinders, which are symmetrically fixedly connected to one end of the installation handle away from the central axis of the adjacent adjustment cylinder. The interior of each installation cylinder is provided with internal threads to facilitate the installation of the cable tray in the working space.

[0011] Furthermore, the connecting mechanism includes a fixed shaft, a connecting handle, a connecting port, and a connecting shaft. The fixed shaft is symmetrically fixed to the inner walls of the left and right sides of the upper fireproof baffle, and the connecting shaft is symmetrically fixed to the inner walls of the left and right sides of the lower fireproof baffle. The outer surface of each fixed shaft is rotatably connected to a connecting handle, and the lower end of each connecting handle is provided with a connecting port. Each connecting port is engaged with the adjacent connecting shaft, thereby improving the connection stability between the lower fireproof baffle and the adjacent upper fireproof baffle.

[0012] Furthermore, the upper fireproof baffle is provided with connecting grooves at both the front and rear ends, and each connecting groove is provided with threaded holes. A connecting plate is inserted between two longitudinally adjacent connecting grooves. Each connecting plate is provided with connecting holes at both the front and rear ends, and bolts are threadedly connected between the connecting holes and the vertically adjacent threaded holes, so as to achieve a stable connection between two longitudinally adjacent upper fireproof baffles, and at the same time achieve a stable connection between two longitudinally adjacent cable trays after installation.

[0013] Furthermore, the bottom four corners of the lower fireproof baffle are provided with recesses. The top walls of the two recesses on the front side of the lower fireproof baffle are fixedly connected to fixing columns. The middle of each fixing column is rotatably connected to a limit plate. The end of the limit plate away from the central axis of the adjacent fixing column is provided with a latch. The top walls of the two recesses on the rear side of the lower fireproof baffle are fixedly connected to connecting columns. The latches are engaged with the adjacent connecting columns, thereby improving the stability of two longitudinally adjacent cable trays after installation.

[0014] Furthermore, the lower fireproof baffle and the upper fireproof baffle are provided with evenly distributed heat dissipation holes at both ends to provide a channel for air exchange inside and outside the cable tray, thereby transferring the heat generated by the cable during operation to the outside.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This tray-type fireproof cable tray has the following advantages:

[0016] 1. By sliding the adjusting cylinder on the outer surface of the corresponding limiting post, the installation handle can be gathered and released inside the gathering groove. Under the rotational support of the adjusting cylinder, the installation handle rotates, thereby adjusting the position of the installation cylinder. This can meet the installation requirements in different working environments, making the installation of the tray-type fireproof cable tray more convenient.

[0017] 2. Using the projection points of the central axes of the fixed shaft and the connecting shaft in the vertical plane as the connecting fulcrum, a trapezoidal mechanism is formed under the connecting action of the connecting handle and the coordinated action of the side plates of the upper and lower fireproof baffles. This achieves longitudinal position locking between the lower fireproof baffle and the adjacent upper fireproof baffle, ensuring the connection stability between the lower fireproof baffle and the adjacent upper fireproof baffle, making the installation of the tray-type fireproof cable tray more secure and stable.

[0025] 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.

[0026] Please see Figure 1-6 This embodiment provides a technical solution: a tray-type fireproof cable tray, including a lower fireproof baffle 1, with an upper fireproof baffle 2 slidably connected to the upper end of the lower fireproof baffle 1. Both the lower fireproof baffle 1 and the upper fireproof baffle 2 can be made of fireproof board composite of glass fiber reinforced material and inorganic adhesive, which has the advantages of light weight, large load, and long service life, and has excellent fireproof and flame-retardant effect, which can effectively prevent the spread of fire and protect cables from fire damage. It also includes an installation mechanism 3 and a connection mechanism 4.

[0027] Installation mechanism 3 includes a gathering groove 31, a limiting post 32, an adjusting cylinder 33, and an installation handle 34. The gathering grooves 31 are symmetrically arranged at the left and right ends of the lower fireproof baffle 1. The middle of each gathering groove 31 is fixedly connected to a limiting post 32. The outer surface of each limiting post 32 is slidably connected to the inner arc surface of the adjacent adjusting cylinder 33. The end of the outer arc surface of each adjusting cylinder 33 away from the center of the lower fireproof baffle 1 is rotatably connected to an installation handle 34. Installation mechanism 3 also includes a limiting groove 36 and a limiting rod 37. The limiting grooves 36 are all located at the middle of the limiting post 32. The inner arc surface of each adjusting cylinder 33 is fixedly connected to a limiting rod 37. The limiting rod 37 is slidably connected to the adjacent limiting groove 36. Installation mechanism 3 also includes an installation cylinder 35. The installation cylinders 35 are symmetrically fixedly connected to the end of the installation handle 34 away from the central axis of the adjacent adjusting cylinder 33. The interior of each installation cylinder 35 is provided with an internal thread to hold the required installation handle. Pulling the mounting handle 34 away from the center of the lower fireproof baffle 1 causes the adjacent adjusting cylinder 33 to move away from the center of the lower fireproof baffle 1. The limiting rods 37 inside the adjusting cylinder 33 slide away from the center of the lower fireproof baffle 1 inside the corresponding limiting grooves 36. When the limiting rods 37 reach the end of the corresponding limiting grooves 36 away from the center of the lower fireproof baffle 1, stop pulling the mounting handle 34. At this time, the mounting handle 34 is completely removed from the inside of the gathering groove 31. Then rotate the mounting handle 34. The rotation of the mounting handle 34 causes the internal mounting cylinder 35 to rotate around the central axis of the adjacent adjusting cylinder 33, thereby realizing the position adjustment of the mounting cylinder 35. When the mounting cylinder 35 can meet the installation requirements of the current working environment, the mounting bolt is threaded into the inside of the corresponding mounting cylinder 35 and passes through the mounting cylinder 35 into the working surface, thereby realizing the stable installation of the tray-type fireproof cable tray.

[0028] Connection mechanism 4: It is disposed between the lower fireproof baffle 1 and the adjacent upper fireproof baffle 2. The connection mechanism 4 includes a fixed shaft 41, a connecting handle 42, a connecting port 43, and a connecting shaft 44. The fixed shaft 41 is symmetrically fixed to the inner walls of the left and right sides of the upper fireproof baffle 2, and the connecting shaft 44 is symmetrically fixed to the inner walls of the left and right sides of the lower fireproof baffle 1. The outer surface of the fixed shaft 41 is rotatably connected to the connecting handle 42. The lower end of the connecting handle 42 is provided with a connecting port 43, and the connecting port 43 is connected to the adjacent connecting shaft. 44. When the upper fireproof baffle 2 is completely vertically aligned with the adjacent lower fireproof baffle 1, the connecting handle 42 is moved towards the center of the lower fireproof baffle 1. The connecting handle 42 rotates around the central axis of the adjacent fixed shaft 41. When the connecting port 43 at the lower end of the connecting handle 42 is engaged with the middle of the adjacent connecting shaft 44, the movement of the connecting handle 42 is stopped. The oblique connection of the connecting handle 42 forms a trapezoidal mechanism, thereby locking the longitudinal position of the upper fireproof baffle 2 with the adjacent lower fireproof baffle 1.

[0029] Wherein: the front and rear ends of the upper fireproof baffle 2 are provided with connecting grooves 9, and the interior of each connecting groove 9 is provided with threaded holes. A connecting plate 10 is inserted between two longitudinally adjacent connecting grooves 9. Both the front and rear ends of the connecting plate 10 are provided with connecting holes. Bolts 11 are threadedly connected between the connecting holes and the vertically adjacent threaded holes. The connecting plate 10 is inserted between two longitudinally adjacent connecting grooves 9, and then the bolts 11 are connected between the connecting holes and the vertically adjacent threaded holes to achieve the connection stability of two longitudinally adjacent upper fireproof baffles 2.

[0030] The lower fireproof baffle 1 has four recesses 5 at its bottom corners. The top walls of the two recesses 5 on the front side of the lower fireproof baffle 1 are fixedly connected to fixing posts 6. The middle of each fixing post 6 is rotatably connected to a limiting plate 7. The end of the limiting plate 7 away from the central axis of the adjacent fixing post 6 is provided with a latch. The top walls of the two recesses 5 on the rear side of the lower fireproof baffle 1 are fixedly connected to connecting posts 8. The latches engage with the adjacent connecting posts 8. The appropriate number of lower fireproof baffles is selected based on the cable length. 1. Arrange each lower fireproof baffle 1 in an orderly manner in the longitudinal direction, then place the cable inside the lower fireproof baffle 1, and then rotate the limiting plate 7 located on the front side of the lower fireproof baffle 1 forward. The limiting plate 7 rotates forward 180 degrees around the central axis of the adjacent fixed column 6. The buckles of the limiting plate 7 are engaged with the middle of the adjacent connecting column 8, thereby realizing the stable connection of two longitudinally adjacent lower fireproof baffles 1. Then slide the corresponding number of upper fireproof baffles 2 into the upper end of the lower fireproof baffle 1.

[0031] The lower fireproof baffle 1 and the upper fireproof baffle 2 are provided with evenly distributed heat dissipation holes 12 at both ends to provide a channel for air exchange inside and outside the cable tray and to transfer the heat generated by the cable during operation to the outside.

[0032] The working principle of the tray-type fireproof cable tray provided by this utility model is as follows: During operation, according to the length of the cable, a corresponding number of lower fireproof baffles 1 are selected, and the lower fireproof baffles 1 are arranged in an orderly manner in the longitudinal direction. Then, the cable is placed inside the lower fireproof baffle 1. Then, the limiting plate 7 located on the front side of the lower fireproof baffle 1 is rotated forward. The limiting plate 7 rotates forward 180 degrees around the central axis of the adjacent fixed column 6. The latches of the limiting plate 7 are engaged with the middle of the adjacent connecting column 8, thereby realizing a stable connection between two longitudinally adjacent lower fireproof baffles 1. Then, personnel... The corresponding number of upper fireproof baffles 2 are slidably connected to the upper end of the lower fireproof baffles 1. After all the upper fireproof baffles 2 are completely vertically aligned with the adjacent lower fireproof baffles 1, personnel move the connecting handles 42 towards the center of the lower fireproof baffles 1. The connecting handles 42 rotate around the central axis of the adjacent fixed shafts 41. When the connecting ports 43 at the lower end of the connecting handles 42 are engaged with the middle of the adjacent connecting shafts 44, the movement of the connecting handles 42 is stopped. The oblique connection of the connecting handles 42 forms a trapezoidal mechanism, thereby locking the longitudinal position of all the upper fireproof baffles 2 with the vertically adjacent lower fireproof baffles 1. Then, the personnel insert the connecting plate 10 between two longitudinally adjacent connecting slots 9, and then connect the bolt 11 between the connecting hole and the vertically adjacent threaded hole to achieve the connection stability of the two longitudinally adjacent upper fireproof baffles 2. Then, the personnel pull the installation handle 34 to be used in a direction away from the center of the lower fireproof baffle 1. The outward movement of the installation handle 34 causes the adjacent adjusting cylinder 33 to move away from the center of the lower fireproof baffle 1. The limiting rods 37 inside the adjusting cylinder 33 slide away from the center of the lower fireproof baffle 1 in the corresponding limiting grooves 36. When the limiting rod 37 reaches the corresponding... When the limiting groove 36 is far away from the center of the lower fireproof baffle 1, stop pulling the installation handle 34. At this time, the installation handle 34 is completely moved out of the inside of the gathering groove 31. Then rotate the installation handle 34. The rotation of the installation handle 34 drives the internal installation cylinder 35 to rotate around the central axis of the adjacent adjusting cylinder 33, thereby realizing the position adjustment of the installation cylinder 35. When the installation cylinder 35 can meet the installation requirements of the current working environment, the personnel thread the installation bolt into the inside of the corresponding installation cylinder 35 and pass it through the installation cylinder 35 into the working surface, thereby realizing the stable installation of the tray-type fireproof cable tray.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
