Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable tray technology, specifically, it relates to a pipeline cable tray device. Background Technology
[0002] In complex engineering systems, cable trays, as a widely used infrastructure, play a crucial role in centrally carrying and organizing cables. Through systematic layout, they orderly integrate previously scattered and disorganized cables, significantly improving the overall structure's organization and functionality. From a space utilization perspective, cable trays effectively prevent disorderly cable stacking, improving space efficiency, making the system layout more compact and rational, and creating conditions for the installation and operation of other equipment. From an operation and maintenance management perspective, the orderly arrangement of cables in cable trays, coupled with clear labeling, greatly facilitates subsequent inspection and maintenance work. Personnel can quickly locate target cables, thereby improving efficiency and reducing operating costs.
[0003] Currently, cable trays still face technical bottlenecks in pipe fixing, with the industry commonly employing multiple clamp joints for segmented fixing. While theoretically feasible, this method presents significant problems in practical application. Due to the long length of the pipes installed, numerous clamps are required for segmented work, and the U-shaped structure of the cable tray itself results in limited internal operating space. Construction workers must perform a series of delicate operations within this confined space, including precise fitting, position adjustment, and reliable connection, demanding extremely high technical precision and easily leading to insecure fixing or damage to the pipe surface. Furthermore, the repetitive installation work further increases the difficulty and complexity of construction, heavily relying on the skill level of the operators, easily causing errors and delays, ultimately affecting the overall construction progress and efficiency of the system.
[0004] Based on this, the present invention proposes a pipeline cable tray device to solve the problems existing in the prior art. Utility Model Content
[0005] In view of this, the main purpose of this utility model is to provide a pipeline cable tray device to solve the problems of difficulty in installing and adjusting clamp joints, easy errors and delays in construction period in the existing cable trays for fixing pipelines.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0007] A cable tray device includes a cable tray frame and a pipe installed on the cable tray frame. The cable tray frame is a horizontally arranged U-shaped steel frame, and a plurality of sliding supports are fixedly installed inside the cable tray frame. The pipe is installed on the upper side of the sliding supports, and a plurality of clamps that are detachably installed inside the cable tray frame to match the pipe are also provided.
[0008] In a preferred embodiment, the clamp is a sheet-like steel strip structure, and connecting portions are formed at both ends of the clamp, the connecting portions being connected to the cable tray frame via connecting bolts.
[0009] In a preferred embodiment, the two ends of the clamp are provided with a number of connecting holes, which are matched with connecting bolts.
[0010] In a preferred embodiment, a rubber friction pad is further provided on the inner side of the clamp, and the rubber friction pad is in contact with the outer surface of the pipe.
[0011] In a preferred embodiment, the sliding support includes a base and a slide block; the base is fixedly disposed inside the cable tray frame; the slide block is slidably disposed on the base, and an arc-shaped notch is specially provided on the slide block in a direction perpendicular to the sliding direction, the arc-shaped notch being adapted to the shape of the pipe.
[0012] In a preferred embodiment, a plurality of rollers are rotatably disposed within the inner limiting cavity of the base, and the rollers are evenly distributed.
[0013] In a preferred embodiment, the roller is also matched with a limiting block disposed at the lower end of the slide.
[0014] In a preferred embodiment, the length of the limiting cavity in the direction perpendicular to the roller is greater than the length of the limiting block.
[0015] In a preferred embodiment, movable grooves are provided on the side plates located at both ends of the roller within the base. A strip is movably installed in the movable groove, and the upper movable groove of the strip matches the roller. A first spring is provided in the lower movable groove of the strip.
[0016] In a preferred embodiment, insert rods are movably mounted at both ends of the roller via second springs. The insert rods are mounted at both ends of the roller via second springs and match the movable grooves on the upper side of the strip.
[0017] Compared with the prior art, the present invention provides a pipeline cable tray device, which has the following advantages:
[0018] 1. By setting up sliding supports;
[0019] (1) Several rollers are rotatably installed in the inner limiting cavity of the base of the sliding support. The limiting block at the lower end of the slide cooperates with the rollers, allowing the slide to slide on the base. Furthermore, the length of the limiting cavity in the direction perpendicular to the rollers is greater than the length of the limiting block, ensuring sliding space. At the same time, the rollers and the limiting block have rolling friction, which greatly reduces the friction force compared to sliding friction, making the slide smoother and less strenuous, and facilitating flexible adjustment of the pipeline position according to actual needs;
[0020] (2) Movable grooves are opened on the side plates at both ends of the roller inside the base. The movable plates are installed in the movable grooves, and the plates cooperate with the rollers to facilitate the installation of the rollers. The rollers are installed with insert rods at both ends by second springs. The insert rods cooperate with the movable grooves on the upper side of the plates to limit their movement. This design not only ensures the convenience of installation, but also makes the position of the rollers relatively stable, thereby ensuring the stability of the entire sliding support for the pipeline.
[0021] (3) A first spring is installed on the underside of the strip plate. When the pipeline experiences micro-vibration during use, the first spring can buffer the strip plate with its own elasticity, disperse and weaken the vibration energy, effectively reduce the impact of vibration on the overall device, provide reliable protection for the pipeline, and extend the service life of the device.
[0022] 2. By setting the clamps;
[0023] (1) The clamp adopts a sheet-like steel strip structure, which allows construction workers to easily wrap it around the outside of the pipe and then fix the clamp to the cable tray frame by connecting the bolts and connecting holes on the two ends of the clamp. The construction process is simple and easy to operate, effectively saving construction time and labor costs.
[0024] (2) Several sets of connection holes are opened on the connection parts at both ends of the clamp. By matching the connection bolts with the connection holes at different positions, the clamp can be well adapted to pipes of different diameters, meet diverse engineering needs, and improve the versatility and practicality of the device.
[0025] (3) A rubber friction pad is adhered to the inside of the clamp. When the clamp fixes the pipe, the rubber friction pad is in close contact with the outer surface of the pipe. The rubber material itself has a large coefficient of friction, which can effectively increase the friction between the clamp and the pipe, thereby making the pipe more securely fixed, reducing the risk of shaking and displacement, and ensuring the stable operation of the pipe on the cable tray frame. This solves the problems of difficult installation and adjustment of clamp joints, easy errors and delays in the construction period of existing cable trays for pipe fixing.

[0039] As per the instruction manual Figures 1-5 As shown, this utility model provides a technical solution:
[0040] A cable tray device includes a cable tray frame 16 and a pipe 1 installed on the cable tray frame 16. The cable tray frame 16 is a horizontally arranged U-shaped steel frame, and several sliding supports 3 are fixedly installed inside the cable tray frame 16. The pipe 1 is installed on the upper side of the sliding supports 3, which are used to limit the position of the pipe 1, thereby reducing the number of clamps 2 used and simplifying the installation process. The pipe 1 is used for cable laying, and several clamps 2 are detachably installed inside the cable tray frame 16 to fix the pipe 1 during installation and use, thereby limiting the lateral and vertical bending of the pipe 1, ensuring the stability and safety of the pipe 1, and ensuring the smooth progress of cable laying.
[0041] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the clamp 2 is a sheet-like steel strip structure with connecting parts at both ends. These connecting parts are connected to the cable tray frame 16 via connecting bolts 4 to fix the pipe 1. In actual construction, the sheet-like steel strip structure of the clamp 2 demonstrates significant advantages. Due to its shape, construction workers can easily install it on the outside of the pipe 1, simplifying the construction process and effectively saving construction time and labor costs. Simultaneously, the sheet-like structure of the clamp 2 allows for large-area effective contact with the pipe 1, increasing friction and ensuring a good fixing effect, thus ensuring the stable operation of the pipe 1 on the cable tray frame 16.
[0042] Specifically, several sets of connecting holes are provided on the connecting parts at both ends of the clamp 2. These connecting holes cooperate with the connecting bolts 4 to provide flexible adjustment space for the installation and use of the clamp 2. In actual construction, since the diameter of the pipe 1 to be fixed varies in different scenarios, the clamp 2 can be well adapted to pipes 1 of different diameters by matching the connecting bolts 4 with the connecting holes at different positions, thereby achieving a stable and reliable fixing effect and meeting diverse engineering needs.
[0043] Specifically, a rubber friction pad 5 is also adhered to the inner side of the clamp 2, which contacts the outer surface of the pipe 1. When the clamp 2 is used to fix the pipe 1, the rubber friction pad 5 will directly contact the outer surface of the pipe 1. The rubber material itself has a large coefficient of friction, which can effectively increase the friction between the clamp 2 and the pipe 1, thereby making the pipe 1 more securely fixed and reducing the risk of shaking and displacement.
[0044] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the sliding support 3 is arranged inside the cable tray frame 16, including a base 7 and a slide 6. The base 7 is securely fixed inside the cable tray frame 16, forming a reliable fixed connection with the cable tray frame 16, providing a stable support foundation for the entire sliding support 3. The slide 6 is slidably mounted on the base 7 and can slide flexibly in a specific direction. An arc-shaped notch is specially provided on the slide 6 along a direction perpendicular to the sliding direction, and this arc-shaped notch is adapted to the shape of the pipe 1. In actual use, this arc-shaped notch can effectively limit and fix the pipe 1, ensuring the stability of the pipe 1 within the cable tray frame 16.
[0045] Specifically, the base 7 is welded and fixed to the inner side of the cable tray frame 16, forming an integral structure with the cable tray frame 16.
[0046] Specifically, a plurality of rollers 9 are rotatably installed within the inner limiting cavity 10 of the base 7. These rollers 9 are evenly distributed and can rotate freely, providing a basis for subsequent cooperation with the slide block 6. The rollers 9 cooperate with the limiting block 8 located at the lower end of the slide block 6. After installation, the upper surface of the rollers 9 will be in close contact with the lower surface of the limiting block 8. In this way, when the slide block 6 slides on the base 7, rolling friction is achieved between the two, which greatly reduces friction compared to sliding friction, making the sliding of the slide block 6 smoother and less strenuous.
[0047] More specifically, the length of the limiting cavity 10 in the direction perpendicular to the roller 9 is greater than the length of the limiting block 8, so that the slide 6 can slide on the base 7, which meets the needs of pipe position adjustment and other operations in actual use. Specifically, after adjustment, the slide 6 can be fixed by filling the gap between the limiting block 8 and the limiting cavity 10 with a block.
[0048] Specifically, movable grooves 12 are provided on the side plates at both ends of the roller 9 within the base 7. A strip 11 is movably installed within these grooves 12. The upper movable groove 12 of the strip 11 cooperates with the roller 9 to facilitate its installation. A first spring 13 is provided on the lower side of the strip 11. The first spring 13 acts as a buffer for the strip 11. When the pipe 1 experiences slight vibration during use, the first spring 13 can use its elasticity to buffer the strip 11, thereby dispersing and weakening the vibration energy, effectively reducing the impact of vibration on the overall device, providing reliable protection for the pipe 1, and extending the service life of the device.
[0049] Specifically, insert rods 14 are movably mounted at both ends of the roller 9 via second springs 15. These insert rods 14 are mounted at both ends of the roller 9 via the second springs 15 and cooperate with the movable groove 12 on the upper side of the strip 11, which limits the position of the insert rods 14. After installation, the insert rods 14, under the combined action of the second springs 15 and the movable groove 12, ensure both a certain degree of freedom of movement and relative stability of the roller 9's position.
[0050] The construction process of the pipeline cable tray device described in this utility model includes:
[0051] When constructing the above-mentioned pipeline cable tray device, first fix the cable tray frame 16, install the base 7 on its inner side and ensure a stable connection; then, in the limiting cavity 10 of the base 7, with the help of the movable characteristics of the strip 11 in the movable groove 12, insert the roller 9. At this time, the insertion rod 14 connected by the second spring 15 at both ends of the roller 9 will be in place under the limiting of the movable groove 12; then, place the limiting block 8 at the lower end of the slide 6 on the roller 9, so that the slide 6 can slide flexibly on the base 7 with the cooperation of the roller 9 and the limiting block 8; then, place the pipe 1 on the slide 6 and match it with the arc-shaped bayonet, and use the arc-shaped bayonet to initially limit it; then, wrap the clamp 2 of the sheet steel strip structure around the outside of the pipe 1, so that the connecting bolt 4 cooperates with the connecting holes on the connecting parts at both ends of the clamp 2, and fix the clamp 2 on the cable tray frame 16. At the same time, the rubber friction pad 5 on the inner side of the clamp 2 is in close contact with the outer surface of the pipe 1 to increase the friction and complete the fixation, and finally realize the installation of the entire pipeline cable tray device.
[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
