Description

Technical Field

[0001] This utility model specifically relates to a cable tray for installing power facilities. Background Technology

[0002] As the core carrier of power transmission, the stable installation and safe operation of cables directly affect the reliability of the entire power system. To achieve orderly cable arrangement and avoid problems such as sagging or tangling due to cable weight or external environmental influences, cable trays are usually used to support and fix the cables. Therefore, cable trays have become an indispensable key auxiliary component in the field of power facility installation.

[0003] For example, Chinese utility model patent with publication number CN219918251U provides a cable tray for power facilities. This cable tray can adapt to the horizontal and vertical offset of the cable by allowing the drive frame in the adjustment assembly to rotate in the front-back direction and the drive frame in the adjustment assembly to rotate in the up-down direction. After the drive frame rotates in the front-back direction and the up-down direction, it can adapt to the horizontal and vertical offset of the cable, thereby improving the support effect of the cable.

[0004] However, most existing cable trays are connected to cables through rigid structures. However, cables are easily shaken by external forces during installation and use. The rigid connection can cause the cable to be subjected to greater tensile force during shaking and bend at the connection between the cable and the tray, which can easily damage the surface protective layer of the cable. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a cable tray for power facility installation. This solves the technical problem mentioned in the background that most existing cable trays are connected to cables through rigid structures. However, cables are easily subjected to external forces and sway during installation and use. The rigid connection can lead to a large pulling force on the cable during swaying, and bending can occur at the connection between the cable and the tray, resulting in damage to the surface protective layer of the cable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable tray for installing power facilities, comprising: Support frame; An installation frame is provided on the support frame, and a mounting seat is slidably provided inside the frame. A first elastic element is provided between both ends of the mounting seat and the inner wall of the installation frame. A support frame is disposed on one side of the mounting base, and a support plate is slidably mounted thereon. Multiple sets of fixing clips are provided on the support plate. A baffle is provided at the bottom of the support plate, and a second elastic element is provided on both sides of the baffle and between the baffle and the load-bearing frame.

[0007] In a preferred embodiment, the inner wall of the support frame is provided with mounting protrusions, and the mounting frame is slidably disposed on the mounting protrusions.

[0008] In a preferred embodiment, the sidewall of the support frame is provided with a plurality of first fixing holes spaced evenly along the longitudinal direction. A first bolt is inserted into the first fixing hole and is screwed to the mounting frame.

[0009] In a preferred embodiment, a reinforcing rib is provided between the mounting base and the support frame.

[0010] In a preferred embodiment, the support plate has multiple sets of second fixing holes spaced evenly in the transverse direction, and the fixing clamp is provided with a second bolt, which is screwed to the support plate.

[0011] In a preferred embodiment, the top of the baffle extends through the support plate and outwards, and its end is provided with a connecting plate, which is detachably connected to the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When in use, this cable tray fixes the support frame in the area of ​​use and secures the cable with clamps. When the cable is subjected to external force and shakes, the mounting base can slide longitudinally within the mounting frame. The first elastic element acts as a longitudinal buffer, reducing the longitudinal pulling force on the cable. The support plate can move laterally, and the baffle and the second elastic element further buffer the lateral shaking of the cable. Through the cooperation of the above structures, the bending amplitude at the connection between the cable and the clamp can be effectively reduced. Through the buffering of the first and second elastic elements and the relative sliding between the components, the external force on the cable is dispersed and alleviated. Compared with traditional rigid connection cable trays, this greatly improves the protection capability of the cable, extends the service life of the cable surface protective layer, and better adapts to the shaking of the cable during installation and use.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0016] Example: like Figures 1 to 3 As shown, this utility model provides a cable tray for power facility installation, including a support frame 1, an installation frame 4 on the support frame 1, an installation seat 6 that is longitudinally slidably arranged inside the installation frame 4, a first elastic element 13 that is arranged between both ends of the installation seat 6 and the inner wall of the installation frame 4, a bearing frame 7 that is arranged on one side of the installation seat 6, a support plate 9 that is laterally slidably arranged on the bearing frame 7, a plurality of fixing clips 11 that are arranged on the support plate 9, a baffle 14 that is arranged at the bottom of the support plate 9, and a second elastic element 16 that is arranged between both sides of the baffle 14 and the bearing frame 7.

[0017] When in use, the cable tray can install cables in the fixing clamps 11, and multiple sets of fixing clamps 11 can be used to install and support multiple sets of cables. When the cable shakes longitudinally during installation and use, it causes the mounting base 6 to slide in the vertical direction. The first elastic element 13 buffers the movement of the mounting base 6 and provides a certain space for the longitudinal movement of the cable. When the cable shakes laterally, it causes the support plate 9 to slide in the horizontal direction. The second elastic element 16 buffers the movement of the support plate 9 and provides a certain space for the lateral movement of the cable. This effectively prevents the cable from being clamped by the fixing clamps 11 and bending significantly when it moves, and avoids damage to the outer protective layer of the cable.

[0018] like Figure 1 , 2As shown, in this embodiment, the inner wall of the support frame 1 is provided with mounting protrusions 3, and the mounting frame 4 is slidably disposed on the mounting protrusions 3. The mounting protrusions 3 are used to position the sliding of the mounting frame 4 of the support frame 1. A plurality of first fixing holes 2 are evenly spaced longitudinally on the side wall of the support frame 1. First bolts 5 are inserted into the first fixing holes 2 and screwed to the mounting frame 4. The height of the mounting frame 4 can be adjusted by inserting the first bolts 5 into the first fixing holes 2 at different heights, thereby adapting to the support of cables of different heights.

[0019] like Figure 1 , 2 As shown, in this embodiment, a reinforcing rib 8 is provided between the mounting base 6 and the bearing frame 7. The arrangement of the reinforcing rib 8 can improve the bearing capacity of the bearing frame 7 and improve the service life of the cable tray.

[0020] like Figure 1 , 4 As shown, in this embodiment, multiple sets of second fixing holes 10 are evenly spaced laterally on the support plate 9, and second bolts 12 are threaded through the fixing clip 11 and screwed to the support plate 9. By installing the second bolts 12 in the second fixing holes 10 at different positions, the horizontal position of the cable can be adapted, further improving the applicability of the cable tray.

[0021] like Figure 2 , 3 As shown, in this embodiment, the top of the baffle 14 passes through the support plate 9 and extends outward, and its end is provided with a connecting plate 15, which is detachably connected to the support plate 9. The support plate 9 can be disassembled by removing the connecting plate 15 and taking out the baffle 14, and then sliding the support plate 9 laterally. This facilitates the inspection of the internal structure of the bearing frame 7, and also makes it convenient to limit the installation of the support plate 9 to prevent it from sliding off the bearing frame 7.

[0022] The specific usage and beneficial effects of this utility model are as follows: When in use, the support frame 1 is fixed in the area of ​​use, and the cable is fixed by the fixing clip 11. When the cable is shaken by external force, the mounting base 6 can slide longitudinally within the mounting frame 4. The first elastic element 13 plays a longitudinal buffering role, reducing the longitudinal pulling force on the cable. The support plate 9 can move laterally, and the baffle 14 and the second elastic element 16 further buffer the lateral shaking of the cable. Through the cooperation of the above structures, the bending amplitude at the connection between the cable and the fixing clip 11 can be effectively reduced. Through the buffering of the first elastic element 13 and the second elastic element 16 and the relative sliding between the components, the external force on the cable is dispersed and relieved. Compared with the traditional rigid connection cable bracket, it greatly improves the protection capability of the cable, increases the service life of the cable surface protective layer, and better adapts to the shaking of the cable during installation and use.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
