Description

Technical Field

[0001] This utility model relates to the field of circuit construction technology, and in particular to a multi-dimensional adjustable support frame for cable trays. Background Technology

[0002] Cable trays are metal or non-metal support systems used to support and protect cables. They are commonly used for cable laying in construction, mining and other places. The support frame is the core component. By fixing the cable tray body, it bears the weight of the cables and the cable tray, prevents deformation or falling, and ensures the stability and flatness of the cable tray installation, ensuring the safe and orderly arrangement of cables.

[0003] A search revealed that the document with publication number "CN222673799U" states, "This utility model discloses a cable tray support frame, relating to the field of cable tray installation technology. It includes a fixed base, a boom hinged to the lower part of the fixed base via pins, a first spring vibration damper hinged to the top of the boom via pins, and the other end of the first spring vibration damper hinged to the fixed base via pins." In use, this cable tray support frame, through the cooperation between the boom and the first screw, allows for easy adjustment of the cable tray's installation height according to the site environment. Through the cooperation between the clamping plates and the fastening bolts, it allows for easy adjustment of the clamping distance for different specifications of cable trays, thus supporting cable trays of different widths. Simultaneously, the cooperation of the first and second spring vibration dampers effectively improves the cable tray's seismic performance, enhances its stability and safety, and prevents swaying, thereby ensuring the normal operation and safe stability of the cables.

[0004] However, in electrical engineering, cable trays are widely used for laying cables to facilitate cable management and maintenance. Traditional cable tray support structures are usually relatively fixed and lack flexible adjustment functions. Common fixed supports can only be installed according to preset positions and heights and cannot be fine-tuned according to actual conditions. When encountering complex building structures or special wiring requirements, such fixed supports often cannot meet the requirements. Some existing adjustable supports can only be adjusted in one direction, such as only adjusting the height up and down or adjusting the position forward and backward, and cannot achieve multi-dimensional comprehensive adjustment. In addition, they are insufficient in terms of stability and load-bearing capacity.

[0005] Therefore, we provide a multi-dimensional adjustable support frame for cable trays to solve the above problems. Utility Model Content

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.

[0030] Please see Figure 1-5 As shown, this utility model provides a technical solution: a multi-dimensional adjustable support frame for cable trays, including a cable tray 1, a cable tray cover 2 installed on the upper side of the cable tray 1, a cable tray support assembly 3 provided on the outer side of the cable tray 1, the cable tray support assembly 3 including a receiving bracket 301 connected to the lower side of the cable tray 1 by slots, a vertical adjustment slot 302 welded on the outer side of the receiving bracket 301, a vertical adjustment rod 303 on the inner side of the vertical adjustment slot 302, a top plate 305 welded to the top of the vertical adjustment rod 303, a turntable cover 306 installed on the upper side of the top plate 305, a horizontal adjustment slot 310 welded to the right side of the top plate 305, an L-shaped adjustment rod 311 installed on the right side of the horizontal adjustment slot 310, a top plate 312 welded to the top of the L-shaped adjustment rod 311, a lower bushing 313 provided on the outer side of the horizontal adjustment slot 310, and an upper bushing 314 welded to the left and right ends of the lower side of the top plate 312.

[0031] Furthermore, a rotating bolt 307 runs through the middle of the turntable cover 306 and the top plate 305. The turntable cover 306 and the rotating bolt 307 are sleeved together. The turntable cover 306 and the top plate 305 are rotated and adjusted by the rotating bolt 307. The top plate 305 and the rotating bolt 307 are threaded together. When installation is required, the staff can adjust the angle of the turntable cover 306 according to the subsequent installation position and lock it by the rotating bolt 307, thereby changing the support direction of the cable tray and improving installation flexibility.

[0032] Furthermore, a limiting side plate 308 is welded to the left side of the turntable cover 306. An adjusting bolt 309 is threadedly connected to the middle of the limiting side plate 308. The end of the adjusting bolt 309 contacts the top plate 305. When needed, the turntable cover 306 is rotated to a suitable angle. Since the turntable cover 306 is a cross-force support point, only the rotating bolt 307 is used for fixing and bearing force. At this time, the adjusting bolt 309 is tightened by the thread, and the end contacts the top plate 305. The limiting side plate 308, together with the turntable cover 306 and the top plate 305, forms a side support structure, which improves the structural stability.

[0033] Furthermore, the vertical adjustment rod 303 and the vertical adjustment slot 302 are connected by a slot, and a limiting bolt 304 passes through the middle of the vertical adjustment slot 302 and the vertical adjustment rod 303. The vertical adjustment rod 303 and the vertical adjustment slot 302, together with the limiting bolt 304, form a lifting and adjusting structure. When needed, the vertical adjustment rod 303 is moved up and down along the vertical adjustment slot 302 according to the required installation height, and the position is fixed by the limiting bolt 304 to realize the height adjustment of the cable tray.

[0034] Furthermore, the L-shaped adjusting rod 311 is connected to the horizontal adjusting slot 310 by a slot and is fixed by an external screw. The L-shaped adjusting rod 311 has a right-angled L-shaped structure. When needed, the L-shaped adjusting rod 311 can be moved left or right along the horizontal adjusting slot 310 according to the distance of the horizontal installation position and tightened by the external screw, thereby extending the horizontal installation distance and improving installation flexibility. By combining the vertical adjusting rod 303 with the lifting adjustment and the horizontal adjustment of the L-shaped adjusting rod 311, multi-dimensional cable tray installation adjustment can be achieved.

[0035] Furthermore, the tightening nut 318 and the screw 315 are connected by a thread. The tightening nut 318 and the screw 315 clamp and limit the upper bushing 314 and the lower bushing 313. When needed, the operator rotates the tightening nut 318 along the screw 315 to apply pressure to the upper bushing 314 and the lower bushing 313, thereby clamping the connecting shaft 316 between the upper bushing 314 and the lower bushing 313, ensuring that the connecting shaft 316 is stable and preventing loosening.

[0036] Furthermore, a screw 315 passes through the middle of both the upper bushing 314 and the lower bushing 313. A connecting shaft 316 is sleeved on the outside of the screw 315. A connecting steel wire 317 is connected in the middle of the connecting shaft 316. A tightening nut 318 is installed at the end of the screw 315. The connecting shaft 316 forms a triangular support structure with the horizontal adjustment slot 310 through the L-shaped adjusting rod 311. When the L-shaped adjusting rod 311 and the horizontal adjustment slot 310 are installed, due to the dispersion of the force support points, the L-shaped adjusting rod 311 is prone to deformation due to excessive force after long-term use. At this time, the connecting steel wire 317 connected in the middle of the connecting shaft 316 can cooperate with the L-shaped adjusting rod 311 and the horizontal adjustment slot 310 to form a triangular structure, thereby improving the tensile strength and ensuring the overall safety.

[0037] Working principle: When needed, first insert the cable tray 1 into the receiving bracket 301. Then, according to the required installation height, adjust the vertical adjustment rod 303 along the vertical adjustment slot 302 and fix it with the limiting bolt 304. Next, according to the required installation width and rotation angle, first rotate the turntable cover 306 along the top plate 305 and fix it with the rotating bolt 307. Simultaneously tighten the adjusting bolt 309. The limiting side plate 308, together with the adjusting plate 308, fixes and supports the turntable cover 306 and the top plate 305. Then, adjust the L-shaped adjusting rod 311 along... The horizontal adjustment slot 310 is pulled out and adjusted to the appropriate width. After that, it is fixedly connected using external bolts. After fixing, the corresponding length of connecting steel wire 317 is inserted into the inner side of the upper bushing 314 and the lower bushing 313 through the connecting shaft 316, and then connected through with screw 315. After preparation, tighten the tightening nut 318 to limit and fix the screw 315. After installation, it is fixed to the preset fixed position by the top plate 312. Finally, the cable tray cover 2 is placed on the cable tray 1. This completes the use process of a multi-dimensional adjustment support frame for cable trays.
