Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a polymer composite cable bridge. Background Art

[0002] Cable tray is a device used to support, protect and arrange cables. It is usually used in buildings, factories and other industrial sites. It is installed on the ceiling, wall or ground to span and support cables so that they are arranged neatly and orderly inside the building, which helps to improve the safety, reliability and maintainability of the cables, while facilitating the repair and replacement of cables.

[0003] The traditional cable tray consists of two side panels with hooks on the outside of the top and a support rod fixedly connected to the bottom of the side panels. The top cover plate is provided with an arc-shaped hook facing inward, and the installation layout is achieved by connecting the arc-shaped hook on the inside of the cover plate with the hooks on the outside of the top of the two side panels.

[0004] However, after the cable is installed in this structure, due to its heavy weight, the support rods at the bottom of the two side panels are pressed, causing the top ends of the two side panels to tilt inward, which results in gaps between the arc-shaped hooks of the two side panels and the arc-shaped hooks of the cover plate, which cannot be tightly engaged, thus easily causing the bridge to become loose and not sealable, resulting in the side panels and the cover being separated during long-term use, or easy entry of rainwater or dust from the outside into the bridge, affecting its service life and easily causing safety hazards. Therefore, a polymer composite cable bridge is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a polymer composite cable tray, which aims to improve the problem that the arc hooks of the traditional structure cannot be tightly engaged with the arc hooks of the cover plate, which is very easy to cause looseness and unsealing, allowing external rain or dust to enter the tray, affecting the service life and easily causing safety hazards.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a polymer composite cable tray, comprising two side panels, the surface of the side panels is provided with reinforcing ribs, the top of the side panels is provided with fixing hooks, a cover plate is provided between the tops of the two side panels, positioning grooves are provided on the left and right sides of the top of the cover plate, component one is provided on the left and right sides of the cover plate, component two is provided on the left and right sides of the bottom of the cover plate, and multiple support components are installed between the two side panels.

[0007] As a further description of the above technical solution:

[0008] The support assembly comprises a steel frame, the left and right sides of which are slidably connected between the insides of the two side panels, the steel frame and the side panels are fixedly connected by two bolts, and the outside of the steel frame is covered with a polymer composite material.

[0009] As a further description of the above technical solution:

[0010] The first component is engaged with the outer side of the fixing hook, and the second component is engaged with the inner side of the fixing hook.

[0011] As a further description of the above technical solution:

[0012] A cover cap is sleeved on the bottom of the bolt.

[0013] As a further description of the above technical solution:

[0014] The cover cap is externally fixedly connected to the bottom of the side plate.

[0015] As a further description of the above technical solution:

[0016] The left and right sides of the top of the cover plate are both arc structures, and the middle side of the top of the cover plate is a flat structure.

[0017] As a further description of the above technical solution:

[0018] The bottom wall of the cover plate is a curved surface structure.

[0019] As a further description of the above technical solution:

[0020] The steel frame is a C-shaped structure as a whole.

[0021] The utility model has the following beneficial effects:

[0022] In the utility model, by transferring the weight to the side panels on both sides, in this process the force direction of the bottom of the side panels on both sides is toward the outside, and the force direction of the top is toward the inside, the fixing hook is squeezed inward to engage with the component two more firmly and tightly, facilitating assembly while ensuring sufficient connection strength and better sealing, achieving the goal of component two becoming tighter and tighter, effectively preventing the deformation and detachment of the cover plate, and significantly improving the structural stability and sealing of the bridge frame.

[0023] In the utility model, the side plates and the bottom C-shaped steel frame of the bridge are made of metal on the inside and are covered with a polymer composite material on the outside, which not only enhances the corrosion resistance of the bridge and prevents rust, but also improves the aesthetics and service life of the bridge and greatly improves safety.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a polymer composite cable tray, comprising two side panels 1, the surface of the side panels 1 is provided with reinforcing ribs 2, the top of the side panels 1 is provided with a fixing hook 3, a cover plate 4 is provided between the tops of the two side panels 1, positioning grooves 5 are provided on the left and right sides of the top of the cover plate 4, components 1 6 are provided on the left and right sides of the cover plate 4, components 2 7 are provided on the left and right sides of the bottom of the cover plate 4, a plurality of supporting components are installed between the two side panels 1, component 1 6 is engaged with the outside of the fixing hook 3, component 2 7 is engaged with the inside of the fixing hook 3, the left and right sides of the top of the cover plate 4 are both arc surface structures, the middle side of the top of the cover plate 4 is a plane structure, and the bottom wall of the cover plate 4 is an arc surface structure.

[0033] Specifically, a trapezoidal wire trough is provided on the surface of the side panel 1. The design of the trapezoidal wire trough provides a larger visual space and is easy to install, while enhancing the overall structural rigidity of the bridge. The front and rear sides of the side panel 1 are fixedly connected with a sheath for protecting the side panel 1. The reinforcing ribs 2 are for further improving the structural strength and rigidity of the bridge and preventing the longitudinal bending deformation of the bridge. The fixing hooks 3 are used to engage with the cover plate 4. The cover plate 4 adopts a curved surface design with arcs at both ends and the inner surface and a flat top in the middle. This design is not only convenient for the stacking and storage of the cover plate 4, but also can effectively disperse the pressure when carrying heavy cables to prevent the cover plate 4 from excessive deformation. The positioning groove 5 is used for positioning. By drilling self-tapping screws from this position, it can be directly connected to the top of the side panel 1 to fix it. Component one 6 and component two 7 are for firmly engaging with the fixing hooks 3 for sealing. Example

[0034] Reference Figure 3 , Figure 5 The utility model provides an embodiment: the top and bottom of the cover plate 4 can also be a flat structure, such as the attached Figure 5 Compared with the curved surface structure of the first embodiment, the manufacturing cost is relatively low and the cost is saved, and it is suitable for narrower bridges or bridges with lighter cables.

[0035] Reference Figure 1 , Figure 3 , Figure 4 The support assembly includes a steel frame 11, and the left and right sides of the steel frame 11 are slidably connected between the inside of the two side panels 1. The steel frame 11 and the side panels 1 are fixedly connected by two bolts 9. The outside of the steel frame 11 is covered with a polymer composite material 8, and the bottom of the bolt 9 is covered with a cover cap 10. The cover cap 10 is fixedly connected to the bottom of the side panel 1. The steel frame 11 is a C-shaped structure as a whole.

[0036] Specifically, a metal frame is provided inside the side panel 1 to support the structure of the side panel 1 and ensure the stability of the structural strength of the side panel 1. The outer layer is coated with a polymer composite material 8. The polymer composite material 8 is used to enhance the corrosion resistance of the bridge frame, prevent rust, improve the aesthetics and service life of the bridge frame, and greatly improve the safety. The design of the C-type structure of the steel frame 11 not only improves the load-bearing capacity of the bridge frame, but also makes the bridge frame lighter and easier to install. The bolts 9 are used to fix the side panel 1 and the steel frame 11. The caps 10 are to protect the bolts 9, prevent the bolts 9 from rusting, and extend the service life.

[0037] Working principle: first install the side panel 1 at the designated position of the building, then place the cable on top of the steel frame 11, and then select a cover plate 4 of appropriate size according to the on-site space, and press the cover plate 4 downward to cover the top of the side panel 1. When the cable is placed on the top of the steel frame 11, the weight of the cable will be pressed on the steel frame 11, and the steel frame 11 transfers the weight to the side panels 1 on both sides. In this process, the force direction of the bottom of the side panels 1 on both sides is toward the outside, and the force direction of the top is toward the inside. The fixing hook 3 on the top is squeezed inward and the engagement between the component 2 7 is more firmly and tightly, which facilitates assembly while ensuring sufficient connection strength and better sealing. The outside of the entire bridge frame is wrapped with a polymer composite material 8 such as the support component. By wrapping the bridge frame with the polymer composite material 8, the entire bridge frame has stronger resistance to rainwater or other weather corrosion, thereby increasing the service life of the bridge frame.

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