Technical Field
[0001] This utility model specifically relates to a fireproof busbar structure that can be easily installed. Background Technology
[0002] In modern power transmission systems, fire-resistant busbars serve as core power distribution equipment in power-intensive locations such as high-rise buildings, data centers, and medical institutions, undertaking the dual functions of efficient power distribution and emergency power supply during fires. Fire-resistant busbars must maintain circuit integrity for 90 to 180 minutes of fire resistance. Their outer shells are typically coated with fire-retardant paint, and their interiors are equipped with fire-resistant mica tape, ceramicized silicone rubber, and other insulating and fire-resistant materials to meet safety requirements in high-temperature environments.
[0003] During the hoisting process, because the surface of the trunking lacks a dedicated attachment structure, rope binding is required during construction. However, the lack of positioning points leads to insecure binding, posing a significant risk of slippage during hoisting, especially in confined spaces such as electrical shafts in high-rise buildings. In the assembly stage, traditional busbar trunking is mostly constructed by bolting horizontal and side plates together. The trunking is heavy and requires manual handling and alignment, which can easily create safety hazards.
[0004] Therefore, it is necessary to invent a fireproof busbar structure that can be easily installed to solve the above problems. Utility Model Content
[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a fireproof busbar structure that can be easily installed and is capable of rapid hoisting.
[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a fireproof busbar trunking structure that can be easily installed, including hoisting components installed on both sides of the fireproof busbar trunking and a transport component at the bottom; The fireproof busbar trunking has grooves on both sides, and the hoisting assembly is installed in the grooves. The hoisting assembly includes a movable plate installed in the groove. The movable plate has limiting plates at its upper and lower ends, which are located on the upper and lower sides of the fireproof busbar trough. An extension plate matching the groove is provided on the inner side of the movable plate. The movable plate is inserted into the groove and moves along the side of the fireproof busbar trough. A screw hole is provided on the movable plate, and a hoisting lug is provided in the screw hole. Multiple limiting assemblies are provided on both the top and bottom sides of the fireproof busbar trough, and the movable plate is positioned between adjacent limiting assemblies. The handling assembly includes multiple fixed shafts fixed to the bottom of the fireproof busbar trough, a rotating plate is mounted on the multiple fixed shafts, and two sets of symmetrical moving slots are provided inside the rotating plate. Handles are installed in the two sets of moving slots. The two ends of the rotating plate rotate to the outside of the fireproof busbar trough, and the handling handles at both ends are placed on both sides of the fireproof busbar trough.
[0007] Preferably, the limiting component includes multiple telescopic grooves disposed on both sides of the top and bottom of the fireproof busbar trough, telescopic protrusions are installed in the multiple telescopic grooves, a telescopic spring is provided between the bottom of the multiple telescopic protrusions and the bottom of the telescopic groove, a mutually matching limiting structure is provided between the bottom edge of the telescopic protrusion and the opening of the telescopic groove, and the moving plate is placed between adjacent telescopic protrusions.
[0008] Preferably, the top of each telescopic protrusion is hemispherical, and the overall height of the telescopic protrusion is higher than the height of the upper and lower ends of the movable plate.

[0018] This utility model provides, for example Figure 1-5 The fireproof busbar structure shown includes a hoisting assembly 2 installed on both sides of the fireproof busbar 1 and a handling assembly 3 at the bottom. The fireproof busbar trunking 1 has grooves 11 on both sides, and the hoisting assembly 2 is installed in the grooves 11. The hoisting assembly 2 includes a movable plate 21 installed in the groove 11. The movable plate 21 has limiting plates 22 at its upper and lower ends. The limiting plates 22 are located on the upper and lower sides of the fireproof busbar trough 1. The inner side of the movable plate 21 has an extension plate 23 that matches the groove 11. The movable plate 21 is inserted into the groove 11 and moves on the side of the fireproof busbar trough 1. The movable plate 21 has screw holes 24 and hoisting ears 25 in the screw holes 24. Multiple limiting assemblies 4 are provided on the top and bottom sides of the fireproof busbar trough 1. The movable plate 21 is positioned between adjacent limiting assemblies 4. The handling assembly 3 includes multiple fixed shafts 31 fixed to the bottom of the fireproof busbar 1. A rotating plate 32 is installed on the multiple fixed shafts 31. The rotating plate 32 has two sets of symmetrical moving slots 33 inside. The two sets of moving slots 33 are equipped with handling handles 34. The two ends of the rotating plate 32 rotate to the outside of the fireproof busbar 1, and the handling handles 34 at both ends are placed on both sides of the fireproof busbar 1.
[0019] The limiting component 4 includes multiple telescopic grooves 41 set on the top and bottom sides of the fireproof busbar trough 1. Telescopic protrusions 42 are installed in the multiple telescopic grooves 41. Telescopic springs 43 are provided between the bottom of the multiple telescopic protrusions 42 and the bottom of the telescopic grooves 41. The bottom edge of the telescopic protrusions 42 and the groove opening of the telescopic grooves 41 are provided with matching limiting structures. The moving plate 21 is placed between adjacent telescopic protrusions 42.
[0020] The top of each telescopic protrusion 42 is hemispherical, and the overall height of the telescopic protrusion 42 is higher than the height of the upper and lower ends of the movable plate 21.
[0021] The end of the lifting lug 25 is provided with a stud 26 that matches the screw hole 24, and the lifting lug 25 is provided with a lifting hole 27.
[0022] The inner wall of the moving groove 33 is provided with rolling grooves 35 on both sides, the bottom of the handling handle 34 is provided with a movable sleeve 36, a rotating shaft 37 is installed in the movable sleeve 36, the two ends of the rotating shaft 37 are set in the rolling grooves 35, and the middle of the rotating plate 32 is provided with a rotating hole 38 that matches the fixed shaft 31.
[0023] The length of the moving groove 33 is such that when the handling handle 34 is moved to the end, it can rotate to a position perpendicular to the rolling groove 35.
[0024] The widths of both the movable plate 21 and the rotating plate 32 do not exceed the distance between adjacent limiting components 4.
[0025] In this embodiment, the telescopic protrusion 42 compresses the telescopic spring 43 and is embedded in the telescopic grooves 41 on both sides of the top and bottom of the fireproof busbar trough 1. The limiting structure of the two edges is used to prevent them from falling off, thus completing the installation of the limiting component 4. Then, the extension plate 23 on the inner side of the moving plate 21 is aligned with the grooves 11 on both sides of the busbar trough and inserted, so that the limiting plates 22 at the upper and lower ends of the moving plate 21 fit against the upper and lower sides of the busbar trough. At this time, the moving plate 21 is located between adjacent telescopic protrusions 42.
[0026] Specifically, according to the on-site hoisting requirements, the movable plate 21 is pushed along the groove 11. When pushed, the movable plate 21 presses the top of the hemispherical telescopic protrusion 42, causing it to compress the spring and retract into the telescopic groove 41. After the movable plate 21 slides to the target position, the telescopic protrusion 42 is reset under the action of the spring and repositioned. Finally, the stud 26 at the end of the hoisting lug 25 is screwed into the screw hole 24 of the movable plate 21 to complete the installation. During hoisting, the hoisting tool can be connected through the hoisting hole 27.
[0027] Specifically, the rotating hole 38 in the middle of the rotating plate 32 is fitted onto the fixed shaft 31 at the bottom of the fireproof busbar trough 1 to connect the rotating plate 32 with the busbar trough; then the movable sleeve 36 at the bottom of the handling handle 34 is fitted onto the rotating shaft 37, and the two ends of the rotating shaft 37 are embedded into the rolling groove 35 on the inner wall of the moving groove 33 of the rotating plate 32 to complete the assembly of the handling component 3.
[0028] Specifically, before handling, rotate the rotating plate 32 around the fixed shaft 31 so that both ends of the rotating plate 32 extend outside the busbar trough; push the handling handle 34 along the rolling groove 35 until it reaches the end of the moving groove 33. At this time, rotate the handling handle 34 around the rotating shaft 37 to a position perpendicular to the rolling groove 35, and the operator can grasp the handle to handle it; when there is no need to handle it, rotate the handle in the opposite direction to retract the moving groove 33, and then rotate the rotating plate 32 back to fit the bottom of the busbar trough.
[0029] In this embodiment, the movable plate 21 can slide along the groove 11 and automatically limit the position with the telescopic protrusion 42, which can quickly adjust the position of the lifting point to adapt to different site requirements; the lifting lug 25 is connected to the screw hole 24 through the stud 26, which eliminates the need for complicated assembly and improves installation efficiency.
[0030] In this embodiment, the hoisting component 2 is hidden in the groove 11, and the handling component 3 can fit against the bottom of the busbar trunking when not in use. The width of the moving plate 21 and the rotating plate 32 does not exceed the spacing between adjacent limiting components 4, and does not protrude from the busbar trunking body, which facilitates stacking, storage and transportation, and reduces the space occupied.
[0031] In this embodiment, the handle can be rotated to a vertical position during handling, which facilitates the application of force and prevents hand slippage during handling; the components have no protruding structures after being stored, which can reduce bumps and damage during transportation and storage and extend the service life of the busbar.
[0032] In this embodiment, the limiting component 4 is automatically reset by the telescopic spring 43 without the need for manual locking, and the limiting structure of the telescopic protrusion 42 and the telescopic groove 41 can prevent the protrusion from falling off; the rotating shaft 37 of the conveying component 3 cooperates with the rolling groove 35 to ensure stable movement and rotation of the handle, and the overall structure operates reliably.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
