Technical Field

[0001] This utility model belongs to the field of cable tray support technology, specifically, it relates to a cable tray support anti-seismic system. Background Technology

[0002] Cable trays, as an important component in cable laying, have advantages such as accommodating a large number of lines, strong transmission capacity, and convenient unified management. They are widely used in industries such as power, light industry, and telecommunications, and are mainly used for laying overhead power cables, control cables, lighting circuits, and telecommunications cables.

[0003] However, in the actual use of existing technology, cable trays are usually fixed with bolts. In order to make the installation more stable, a suitable mounting plate is usually used for connection to further enhance the stability of the cable tray. However, this method is prone to problems during installation because the bolts are not properly fixed.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a seismic-resistant system for cable tray supports.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A seismic-resistant system for cable tray supports includes a support base plate, support frames at both ends of the support base plate, two auxiliary diagonal braces at both ends of the support base plate, and a cable tray body on the upper side of the support base plate.

[0008] Two L-shaped mounting plates are provided on the upper side of the support base plate. Fixing bolts are provided on the upper side of the L-shaped mounting plates, and fixing grooves are provided on one side of the L-shaped mounting plates, with screws installed in the fixing grooves.

[0009] The L-shaped mounting plate has a cavity that communicates with the fixing groove, and a lever plate is movably connected in the fixing groove. A rotating frame connected to the lever plate is rotatably fitted in the cavity. A limit block is provided on one side of the rotating frame. A through groove is opened in the L-shaped mounting plate, and a positioning plate is elastically fitted in the through groove. A limit groove is provided on one side of the positioning plate that engages with the limit block.

[0010] Optionally, guide grooves are provided on both sides of the inner wall of the fixing groove, and the side plates on both sides of the positioning plate are slidably fitted in the guide grooves.

[0011] Optionally, the dial plate has a through hole, and the screw body is located inside the through hole.

[0012] Optionally, torsion springs are provided on both sides of the rotating frame, with one side of the torsion spring connected to the inner wall of the cavity.

[0013] Optionally, two limiting guide frames are provided on the upper side of the support base plate, and limiting plates are provided on both sides of the L-shaped mounting plate. The limiting plates slide within the limiting guide frames.

[0014] Optionally, two auxiliary diagonal braces are hinged to both sides of the support base plate, with one auxiliary diagonal brace located on the side of the support base plate and the other auxiliary diagonal brace located on the longitudinal surface of the support base plate; one end of each auxiliary diagonal brace is movably connected to a fixing plate, and the fixing plate has multiple fixing holes.

[0015] Optionally, expansion anchors are provided on the upper side of the support frame.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] The positioning plate, once the screws are in place, can be released from its position by a lever and a rotating bracket. This allows the positioning plate to protect and secure the screws under its own elasticity, preventing them from loosening after installation. It also prevents the positioning plate from falling if a screw is not properly installed, alerting installers to any misalignment and further improving the stability of the cable tray in actual use. The guide groove further limits the movement of the positioning plate and provides stable protection against loose screws, enhancing safety after installation and significantly reducing the likelihood of the cable tray becoming loose during use.

[0029] Please see Figure 1-5 As shown, this embodiment provides a cable tray support seismic system, including a support base plate 1, support frames 2 are provided at both ends of the support base plate 1, two auxiliary diagonal braces 3 are provided at both ends of the support base plate 1, and a cable tray body 4 is provided on the upper side of the support base plate 1.

[0030] Two L-shaped mounting plates 5 are provided on the upper side of the support base plate 1. Fixing bolts 6 are provided on the upper side of the L-shaped mounting plates 5. Fixing grooves 7 are provided on one side of the L-shaped mounting plates 5. Screws 8 are provided in the fixing grooves 7.

[0031] The L-shaped mounting plate 5 has a cavity that communicates with the fixing groove 7, and a lever 9 is movably connected in the fixing groove 7. A rotating frame 10 connected to the lever 9 is rotatably fitted in the cavity. A limit block 11 is provided on one side of the rotating frame 10. A through groove is opened in the L-shaped mounting plate 5, and a positioning plate 12 is elastically fitted in the through groove. A limit groove 13 that engages with the limit block 11 is provided on one side of the positioning plate 12.

[0032] like Figure 3-4 As shown, guide grooves 14 are provided on both sides of the inner wall of the fixing groove 7 in this embodiment, and the side plates on both sides of the positioning plate 12 are slidably fitted in the guide grooves 14.

[0033] like Figure 5 As shown, the dial plate 9 in this embodiment has a through hole 15, and the screw 8 is located inside the through hole 15.

[0034] like Figure 3-5 As shown, in this embodiment, torsion springs 16 are provided on both sides of the rotating frame 10, and one side of the torsion spring 16 is connected to the inner wall of the cavity.

[0035] like Figure 1-3 As shown, in this embodiment, two limiting guide frames 17 are provided on the upper side of the support base plate 1, and limiting plates are provided on both sides of the L-shaped mounting plate 5. The limiting plates are slidably fitted within the limiting guide frames 17.

[0036] like Figure 1-2 As shown, in this embodiment, the two auxiliary diagonal braces 3 are respectively hinged to the two sides of the support base plate 1. One auxiliary diagonal brace 3 is located on the side of the support base plate 1, and the other auxiliary diagonal brace 3 is located on the longitudinal surface of the support base plate 1. One end of each of the two auxiliary diagonal braces 3 is movably connected to a fixing plate 18, and the fixing plate 18 is provided with a plurality of fixing holes 19.

[0037] like Figure 1 As shown, an expansion anchor 20 is provided on the upper side of the support frame 2 in this embodiment.

[0038] In this embodiment, a spring is provided at one end of the positioning plate 12, and one end of the spring is connected to the inner wall of the through groove.

[0039] One application of this embodiment is as follows: When it is necessary to fix the cable tray body 4, firstly, the two support frames 2 and the support base plate 1 are installed on the predetermined wall top using expansion anchors 20. Then, the cable tray body 4 to be installed is placed on the support base plate 1, and the L-shaped mounting plate 5 is moved within the limiting guide frame 17 to move to one side of the cable tray body 4. After the movement, the position of the L-shaped mounting plate 5 is first fixed using fixing bolts 6. After fixing, the cable tray body 4 is then fixed using screws. During the fixing process, the nuts on the screws 8 will drive the lever plate 9 to move. The movement of the lever plate 9 can... The rotating frame 10 rotates slightly around the two torsion springs 16. During the rotation, the limiting block 11 can be squeezed out from the limiting groove 13 on the positioning plate 12. This releases the limiting on the positioning plate 12 when the screw 8 is installed in place. After the limiting is released, the positioning plate 12 can move under the elastic force of the spring itself. Under the limiting of the two guide grooves 14, the positioning plate 12 can block and limit the screw 8, preventing the screw 8 from loosening during use. After installation, the two auxiliary diagonal braces 3 are fixed through the fixing holes 19 on the fixing plate 18 by expansion screws or bolts, thus completing the installation of the cable tray.

[0040] With the positioning plate 12 in place, after the screw 8 is installed in place, the limiting block 11 can be released from the positioning plate 12 by the lever 9 and the rotating frame 10. This allows the positioning plate 12 to protect and fix the screw in place under its own elasticity, while preventing the screw 8 from loosening after installation. It also prevents the positioning plate 12 from falling if the screw 8 is not installed in place, reminding the installer that the screw 8 is not installed in place. This further improves the stability of the cable tray in actual use. With the guide groove 14 in place, the movement of the positioning plate 12 can be limited. If the screw 8 becomes loose later, the guide groove 14 can stably block the loose screw, improving the safety of the cable tray after installation and greatly reducing the possibility of the cable tray becoming loose during use.

[0041] With the torsion spring 16 in place, the limiting plate 11 on the rotating frame 10 can press and limit the positioning plate 12. Only when the screw 8 drives the lever 9 to move can the limitation on the positioning plate 12 be released. This can prevent the positioning plate 12 from falling off prematurely due to vibration or other factors during installation, ensuring the stability of the positioning plate 12 before use. Through the limited guide frame 17, the L-shaped mounting plate 5 can slide within the limited guide frame 17 before being fixed. This not only limits the L-shaped mounting plate 5 but also prevents it from falling off during the installation of the cable tray, making installation convenient. While the installers are operating the system, the safety issue of personnel below being injured by falling L-shaped mounting plates 5 during installation is also resolved. With the setting of multiple auxiliary diagonal braces 3, the cable trays can be prevented from falling off or shaking at different installation angles, both lateral and longitudinal, thus avoiding cable tray misalignment or falling. This improves the seismic resistance of the entire seismic support and the overall safety of the support system. Furthermore, with the installation of expansion anchors 20, it is easy to fix the support frame 2 to the predetermined wall top, facilitating the installation and positioning of the overall cable tray frame, making subsequent cable tray installation more convenient and labor-saving.
