Description

Technical Field

[0001] This utility model relates to the technical field of electrical cable tray support structure, specifically an electrical installation support structure. Background Technology

[0002] Lateral support structures for electrical cable trays are mechanical support devices used in cable systems. They mainly use components such as brackets, hangers, or connectors to fix the cable trays to the side or bottom of a building structure. Through reasonable mechanical design, this structure can effectively distribute the self-weight of the cables and external loads, preventing lateral displacement or deformation of the cable trays, while avoiding wear, corrosion, or mechanical damage to the cables due to direct contact with walls, floors, or other external environments.

[0003] Extensive searching revealed CN222169214U, which discloses a high-strength lateral support structure for electrical cable trays. The structure includes a bracket and a sliding groove. Sliding grooves are machined on the front and rear sides of the bottom inner wall of the bracket. A partition structure connects to the inner wall of the sliding groove. Bending plates are fixed to the bottom of the left and right sides of the bracket, and a base frame is fixed to the bottom of each bending plate. A handle in the partition structure drives a ring to rotate downwards on the outer wall of a first screw, causing the top of the ring to detach from the bottom of the bracket. The first screw then slides left and right on the inner wall of the sliding groove. This left-right sliding of the first screw, along with a straight plate, adjusts the space within the bracket. Finally, the handle rotates the ring upwards on the outer wall of the first screw, causing the top of the ring to abut against the bottom of the bracket. This improves the protective performance of the lateral support structure for electrical cable trays and ensures its normal operation.

[0004] However, existing technologies still have shortcomings. The main limitation lies in the base support structure, which uses a rigid connection between the bent plate and the cable tray body. While this provides lateral adjustment, the fixed connection between the base and the cable tray makes it difficult to easily add auxiliary reinforcement devices to the existing support system when the cable tray load increases. This structural limitation means that when the cable laying density exceeds the design load, the load-bearing capacity of the support system cannot be increased synchronously, posing a safety hazard of the cable tray overturning or breaking due to gravity overload. Therefore, an electrical installation support structure is proposed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical installation support structure that has the advantages of strong load adaptability, convenient installation and flexible expansion of reinforcement components. It solves the problem in the prior art that the rigid connection between the support structure and the cable tray makes it difficult to flexibly add reinforcement measures under heavy loads, which can easily lead to structural instability.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an electrical installation support structure, including a cable tray, an installation component is slidably installed on the outer side of the cable tray, a lower guide rail and an upper guide rail are fixedly installed on both sides of the cable tray respectively, the lower guide rail and the upper guide rail are welded to the outer wall of the cable tray respectively, and the longitudinal section of the lower guide rail adopts an L-shaped structure design;

[0007] The mounting assembly includes a threaded tie rod, the bottom of which is movably mounted with a first connecting bracket via an adjusting nut. A second connecting bracket is rotatably mounted on one side of the first connecting bracket, and the second connecting bracket is slidably mounted on the opposite side of the lower guide rail and the upper guide rail.

[0008] Preferably, the top of the cable tray is fitted with a cover plate, and the bottom of the cable tray has a rectangular array of reserved holes.

[0009] The design incorporates a movable, snap-fit ​​cover at the top of the cable tray and pre-drilled holes arranged in a rectangular array at the bottom, enabling convenient maintenance and orderly cable securing. The snap-fit ​​connection of the cover facilitates quick opening and closing, while the pre-drilled holes allow for standardized cable bundling with fasteners, preventing cable displacement due to gravity or vibration.

[0010] Preferably, holes are opened on the outer walls of the bridge frame at both ends of the lower guide rail and the upper guide rail on opposite sides, and concealed nuts are embedded therein.

[0011] In the design, the positioning bolts are quickly installed by embedding concealed nuts into the outer wall of the cable tray on the opposite side of the lower and upper guide rails.

[0012] Preferably, the concealed nut is threaded with a positioning bolt, the outer diameter of the bolt head of the positioning bolt is smaller than the distance between the opposite sides of the lower guide rail and the upper guide rail, and the bolt head of the positioning bolt is located on the opposite side of the lower guide rail and the upper guide rail.

[0013] The design effectively seals the gap between the guide rails by using concealed nuts and positioning bolts. The bolt heads of the positioning bolts are located on the opposite side of the lower and upper guide rails. After being fixed by threaded connection, they prevent the mounting components from accidentally sliding off the guide rail grooves, ensuring the stability of the support structure during dynamic adjustment.

[0014] Preferably, the mounting assembly further includes an expansion body, which is welded to the top of the threaded tie rod, and an expansion tube is movably fitted on the outside of the expansion body.

[0015] In the design, a reliable connection between the support assembly and the building substrate is achieved by welding an expansion body to the top of the threaded tie rod and an expansion tube that is movable on the outside. The cooperation between the expansion body and the expansion tube can form a mechanical anchorage in the pre-set holes in the building structure, ensuring the vertical load-bearing capacity of the support system.

[0016] Preferably, a fastening nut is threaded onto the top of the threaded rod, and a washer is movably fitted onto the threaded rod above the fastening nut. The inner diameter of the washer is smaller than the outer diameter of the expansion tube.

[0017] In the design, the uniform transmission of anchoring force is achieved through the fastening nut at the top of the threaded tie rod and the washer in the upper movable sleeve. The limiting fit between the inner diameter of the washer and the outer diameter of the expansion tube effectively disperses the anchoring stress, avoids local overload, and ensures the stability of the support assembly under long-term load.

[0018] Preferably, the upper end face of the first connecting bracket contacts the lower end face of the upper guide rail but is not fixedly connected.

[0019] In the design, the dynamic adaptability of the support system is achieved through a non-fixed connection structure between the upper end face of the first connecting frame and the lower end face of the upper guide rail. This design allows the mounting components to slide freely within a certain range.

[0020] Preferably, the bottom of the second connecting frame is slidably mounted on the side opposite to the lower guide rail and the bridge frame.

[0021] In the design, the sliding structure of the bottom of the second connecting frame and the lower guide rail enables stepless adjustment of the support point position. The second connecting frame can be adjusted arbitrarily along the length of the cable tray, and the support height can be precisely positioned in conjunction with the adjusting nut, improving the flexibility and applicability of the overall structure.

[0022] The beneficial effects of this utility model are:

[0023] This utility model, through the sliding design of the installation components, allows the support point position to be adjusted arbitrarily along the lower and upper guide rails. With the help of the adjusting nut, the support height can be infinitely adjusted, thereby dynamically optimizing the support layout according to the cable load distribution and improving the overall load-bearing capacity.

[0024] The anchoring structure of the expansion body and expansion tube simplifies the connection with the building base and eliminates the need for complex pre-embedded parts; the rotating fit design of the first connecting frame and the second connecting frame can quickly complete the positioning and fixing of the installation components, reducing the difficulty of construction.

[0025] The guide rail sliding structure allows for the convenient addition of auxiliary reinforcement devices along the length of the cable tray without removing the original support, solving the problem of the traditional rigid connection support system being difficult to expand under heavy loads, and effectively preventing the cable tray from becoming unstable or breaking due to overload.

[0026] The non-fixed contact design between the first connecting bracket and the upper guide rail allows the installation components to adjust themselves within a certain range. Combined with the sealing effect of the positioning bolts on the guide rail gap, this significantly improves the stability of the support system under dynamic loads. Attached Figure Description

[0033] 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.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: an electrical installation support structure, including a cable tray 1, an installation component 3 slidably installed on the outer side of the cable tray 1, a lower guide rail 12 and an upper guide rail 13 respectively fixedly installed on both sides of the cable tray 1, the lower guide rail 12 and the upper guide rail 13 are respectively welded to the outer wall of the cable tray 1, and the longitudinal section of the lower guide rail 12 adopts an L-shaped structure design.

[0036] Mounting assembly 3 includes a threaded tie rod 31. A first connecting bracket 32 ​​is movably mounted on the bottom of the threaded tie rod 31 via an adjusting nut 311. A second connecting bracket 33 is rotatably mounted on one side of the first connecting bracket 32. The second connecting bracket 33 is slidably mounted on the opposite side of the lower guide rail 12 and the upper guide rail 13.

[0037] Specifically, through the sliding design of the mounting component 3, the position of the support point can be adjusted arbitrarily along the lower guide rail 12 and the upper guide rail 13. With the help of the adjusting nut 311, the support height can be infinitely adjusted, thereby dynamically optimizing the support layout according to the cable load distribution and improving the overall load-bearing capacity.

[0038] The anchoring structure of the expansion body 34 and the expansion tube 35 simplifies the connection with the building base and eliminates the need for complex pre-embedded parts; the rotational fit design of the first connecting frame 32 and the second connecting frame 33 can quickly complete the positioning and fixing of the installation component 3, reducing the difficulty of construction.

[0039] The guide rail sliding structure allows for the convenient addition of auxiliary reinforcement devices along the length of the cable tray 1 without removing the original support, solving the problem that traditional rigid connection support systems are difficult to expand under heavy loads, and effectively preventing the cable tray 1 from becoming unstable or breaking due to overload.

[0040] The non-fixed contact design between the first connecting bracket 32 ​​and the upper guide rail 13 allows the mounting component 3 to adjust itself within a certain range. Combined with the sealing effect of the positioning bolts 14 on the guide rail gap, this significantly improves the stability of the support system under dynamic loads.

[0041] Example 2

[0042] To achieve convenient maintenance of cable trays and orderly cable fixing, such as Figure 1 , Figure 2 and Figure 3 As shown in this embodiment, the top of the cable tray 1 is movably fitted with a cover plate 2, and the bottom of the cable tray 1 has a rectangular array of reserved holes 11.

[0043] In the design, the cover plate 2, which is movably snapped onto the top of the cable tray 1, and the pre-drilled holes 11 arranged in a rectangular array at the bottom, enable convenient maintenance of the cable tray 1 and orderly fixation of the cables. The snap-fit ​​connection of the cover plate 2 facilitates quick opening and closing, and the pre-drilled holes 11 can be used with fasteners to standardize the bundling of cables, preventing displacement of the cables due to gravity or vibration.

[0044] Furthermore, holes are opened on the outer walls of the bridge frame 1 at both ends of the lower guide rail 12 and the upper guide rail 13 on opposite sides, and concealed nuts 15 are embedded and installed.

[0045] In the design, the positioning bolt 14 is quickly installed by embedding the concealed nut 15 into the outer wall of the bridge frame 1 on the opposite side of the lower guide rail 12 and the upper guide rail 13.

[0046] Furthermore, a positioning bolt 14 is installed on the internal thread of the concealed nut 15. The outer diameter of the bolt head of the positioning bolt 14 is smaller than the distance between the lower guide rail 12 and the upper guide rail 13 on opposite sides. The bolt head of the positioning bolt 14 is located on the opposite side of the lower guide rail 12 and the upper guide rail 13.

[0047] The design effectively seals the gap between the guide rails by using the concealed nut 15 and the positioning bolt 14. The bolt head of the positioning bolt 14 is located on the opposite side of the lower guide rail 12 and the upper guide rail 13. After being fixed by threaded connection, it can prevent the mounting component 3 from accidentally sliding down the guide rail groove, ensuring the stability of the support structure during dynamic adjustment.

[0048] Example 3

[0049] To achieve a reliable connection between the support components and the building substrate, such as Figure 4 As shown, in this embodiment, the mounting assembly 3 also includes an expansion body 34, which is welded to the top of the threaded tie rod 31, and an expansion tube 35 is movably fitted on the outside of the expansion body 34.

[0050] In the design, a reliable connection between the support assembly and the building substrate is achieved by welding an expansion body 34 to the top of the threaded tie rod 31 and an expansion tube 35 that is movably fitted on the outside. The cooperation between the expansion body 34 and the expansion tube 35 can form a mechanical anchorage in the pre-set holes in the building structure, ensuring the vertical load-bearing capacity of the support system.

[0051] Furthermore, a fastening nut 312 is threadedly installed on the top of the threaded rod 31, and a washer 313 is movably fitted on the threaded rod 31 above the fastening nut 312. The inner diameter of the washer 313 is smaller than the outer diameter of the expansion tube 35.

[0052] In the design, the anchoring force is evenly transmitted through the fastening nut 312 at the top of the threaded tie rod 31 and the washer 313 in the upper movable sleeve. The limiting fit between the inner diameter of the washer 313 and the outer diameter of the expansion tube 35 can effectively disperse the anchoring stress, avoid local overload, and ensure the stability of the support component under long-term load.

[0053] Furthermore, the upper end face of the first connecting bracket 32 ​​contacts the lower end face of the upper guide rail 13 but is not fixedly connected.

[0054] In the design, the dynamic adaptability of the support system is achieved through a non-fixed connection structure between the upper end face of the first connecting frame 32 and the lower end face of the upper guide rail 13. This design allows the mounting component 3 to slide freely within a certain range.

[0055] Furthermore, the bottom of the second connecting frame 33 is slidably mounted on the side opposite to the lower guide rail 12 and the bridge frame 1.

[0056] In the design, the sliding structure between the bottom of the second connecting frame 33 and the lower guide rail 12 enables stepless adjustment of the support point position. The second connecting frame 33 can be adjusted arbitrarily along the length of the cable tray 1, and the support height can be precisely positioned in conjunction with the adjusting nut 311, thereby improving the flexibility and applicability of the overall structure.

[0057] In use, the lower guide rail 12 and the upper guide rail 13 are welded and fixed to the outer walls of both sides of the cable tray 1, ensuring that the L-shaped lower guide rail 12 and the upper guide rail 13 are parallel to the top surface of the cable tray. Holes are made in the outer wall of the cable tray on the opposite side of the guide rails, and concealed nuts 15 are inserted and installed.

[0058] The expansion body 34 is welded to the top of the threaded tie rod 31. After the expansion tube 35 is installed, the fastening nut 312 and washer 313 are screwed in in sequence to allow the expansion tube to slide to a certain extent. The first connecting bracket 32, on which the second connecting bracket 33 is rotatably mounted, is movably mounted to the bottom end of the threaded tie rod 31 by adjusting the nut 311.

[0059] Slide the bottom of the second connecting bracket 33 into the mating surface of the lower guide rail 12 and the cable tray 1, while simultaneously ensuring that the upper surface of the first connecting bracket 32 ​​is in contact with the bottom surface of the upper guide rail 13. Insert the expansion tube 35 into the pre-drilled hole in the building structure, and finally tighten the fastening nut 312 to complete the anchoring. Adjust the overall height of the cable tray by rotating the adjusting nut 311, and simultaneously screw the positioning bolt into the concealed nut to prevent the installed components from slipping.

[0060] When the load on the cable tray increases, the positioning bolts can be loosened and installation components can be added to increase auxiliary support points and achieve multi-dimensional reinforcement. Furthermore, after the cable laying is completed, the cover plate 2 must be clipped onto the top of the cable tray, and the cables can be bundled and secured through the pre-drilled holes 11 at the bottom.

[0061] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.

[0062] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
