Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, specifically to a cable tray support device used in power construction. Background Technology

[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or laid on various building structures and pipe rack supports to support cables.

[0003] A relevant reference is Chinese utility model patent CN220857536U, which discloses a cable tray support device, including a fixed frame. The fixed frame has folding grooves at both ends, and limiting rotating grooves located on both sides of the folding grooves are formed inside the bottom of the fixed frame. A rotating shaft is rotatably connected to the bottom of the fixed frame. A receiving block is integrally formed in the middle of the rotating shaft, located inside the folding groove. Limiting blocks are integrally formed at both ends of the rotating shaft, located inside the limiting rotating groove. A return spring is provided inside the limiting rotating groove, located on one side of the limiting block. By inserting the cable tray into the fixed frame from the bottom, the receiving block rotates upwards into the folding groove. When the cable tray is fully inside the fixed frame, it rotates in the opposite direction under the action of the return spring, and the limiting blocks abut against the inner wall of the limiting rotating groove, making the top of the receiving block horizontal. Placing the cable tray on the receiving block prevents the cable tray from falling, making the installation of the cable tray more convenient.

[0004] The aforementioned cable tray support device uses a spring to drive the receiving block to return to a horizontal position to support the cable tray. This method requires the cable tray to move upwards into the support device and directly above the receiving block to prevent the cable tray from blocking the receiving block from returning to its horizontal position. After installation, a certain space will be left between the cable tray and the ceiling, resulting in a reduction in the installation height of the cable tray, which poses a certain safety hazard. Furthermore, the spring will apply tension to the receiving block. During the maintenance of the cable tray, the receiving block will remain in a horizontal position under the action of the spring, which will hinder the operation of construction personnel and is very inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cable tray support device for power construction, which solves the problems of high space occupation and inconvenient maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cable tray support device for power construction includes a slide rail, and a limit mechanism is provided below the slide rail.

[0007] A connecting component, located below the slide rail, is used to connect the slide rail and the support component;

[0008] The support assembly includes a limiting frame disposed below the connecting assembly. A connecting shaft is inserted and installed below the limiting frame. A support plate is fixedly installed on the outer side of the connecting shaft. A secondary screw is inserted and installed at the center of the limiting frame. A driving block is inserted and installed on the outer side of the secondary screw. A rack is inserted and installed on one side of the driving block. A limiting post is inserted and installed inside the driving block.

[0010] Preferably, the top of the connecting frame is inverted "V" shape, and the support wheels are symmetrically installed on the outside of the columnar structure at the top of the connecting frame. The support wheels are rotatably connected to the connecting frame through bearings.

Beneficial effects

[0014] This utility model provides a cable tray support device for power construction. Compared with the prior art, it has the following advantages:

[0015] (1) The cable tray support device for power construction, through the setting of the rack, and through the linkage of the secondary screw, drive block, rack and support plate, when the secondary screw is rotated, its bottom thread engages with the groove on the inner wall of the drive block. Because the limit post restricts the rotation of the drive block, the drive block moves vertically along the limit post, driving the rack to move synchronously. The rack meshes with the central gear of the support plate, precisely driving the support plate to rotate around the connecting shaft to horizontally support the cable tray. At the same time, the upper thread of the secondary screw engages with the limit block, pulling the connecting frame to move upward along the guide post, reducing the distance between the connecting frame and the limit frame, realizing precise control of the cable tray height, avoiding the stress fatigue and spacing redundancy problems of traditional spring drive, providing stable support and eliminating safety hazards.

[0016] (2) The cable tray support device for power construction has a support wheel. The support wheel is rotatably connected to the connecting frame through the bearing, so that the connecting frame can slide along the slide rail with the help of the support wheel. During maintenance, the secondary screw is rotated in the opposite direction at a certain angle to increase the distance between the connecting frame and the limiting frame. At this time, the limiting mechanism does not bear the weight of the cable tray. The weight of the cable tray is shared by the other limiting mechanisms below the slide rail. Then, the limiting mechanism can be moved to the non-maintenance area by sliding and the secondary screw is rotated in the forward direction to restore the supporting state of the limiting mechanism, so as to facilitate maintenance operations on the contact part between the cable tray and the support device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cable tray support device for power construction, including a slide rail 1, and a limit mechanism 2 is provided below the slide rail 1.

[0024] A connecting component 21 is disposed below the slide rail 1 to connect the slide rail 1 and the support component 22. The connecting component 21 includes a connecting frame 211 fitted and installed below the slide rail 1. A bearing 212 is fixedly installed at the upper end of the connecting frame 211. A support wheel 213 is inserted and installed on the outer side of the bearing 212. A limit block 214 is fixedly installed at the bottom end of the connecting frame 211. A guide post 215 is inserted and installed at the bottom of the connecting frame 211. The top end of the connecting frame 211 is inverted "V" shape. The support wheel 213 is symmetrically installed on the outer side of the columnar structure at the top end of the connecting frame 211. The support wheel 213 is rotatably connected to the connecting frame 211 through the bearing 212. The connecting frame 211 is movably connected to the slide rail 1 through the support wheel 213. The bottom end of the guide post 215 is fixedly connected to the top surface of the limit frame 221. The guide post 215 and the connecting frame 211 are slidably connected.

[0025] Specifically, there are two slide rails 1, which are fixed to the ceiling with bolts to restrict the movement direction of the connecting component 21. The connecting frame 211 can restrict the position of the support wheel 213. Since the support wheel 213 is rotatably connected to the connecting frame 211 through the bearing 212, the connecting frame 211 can slide inside the slide rail 1 through the support wheel 213. The limiting block 214 can connect the connecting frame 211 to the top of the secondary screw 224. The guide post 215 is located at the four corners of the bottom of the slide rail 1 and is slidably connected to the slide rail 1 to prevent the relative angle between the limiting frame 221 and the connecting frame 211 from being affected when the secondary screw 224 rotates.

[0026] The support assembly 22 includes a limiting frame 221 disposed below the connecting assembly 21. A connecting shaft 222 is inserted and installed below the limiting frame 221. A support plate 223 is fixedly installed on the outer side of the connecting shaft 222. A secondary screw 224 is inserted and installed at the center of the limiting frame 221. A drive block 225 is inserted and installed on the outer side of the secondary screw 224. A rack 226 is inserted and installed on one side of the drive block 225. A limiting post 227 is inserted and installed inside the drive block 225. The limiting frame 221 and the connecting shaft 222 are connected. A rotating connection is formed, with a gear structure at the center of the support plate 223. The secondary screw 224 is rotatingly connected to the support plate 223. The top end of the secondary screw 224 is inserted into the interior of the limiting block 214. The inner wall of the driving block 225 is provided with a groove that fits into the threaded structure at the bottom of the secondary screw 224. The rack 226 meshes with the central gear structure of the support plate 223. The top end of the limiting post 227 is fixedly connected to the limiting frame 221. The limiting post 227 and the driving block 225 are slidingly connected.

[0027] Specifically, the limiting frame 221 can restrict the position of the lower support plate 223. Since the central gear structure of the support plate 223 meshes with the rack 226, and the rotation angle of the drive block 225 is limited by the limiting post 227, the drive block 225 can only move in the vertical direction. When the secondary screw 224 rotates, it will drive the drive block 225 and the rack 226 on one side of the drive block 225 to move downward, thereby driving the support plate 223 to rotate to a horizontal state with the axis of the connecting shaft 222 as the reference through the rack 226. At the same time, the threaded structure at the upper end of the secondary screw 224 will reduce the distance between the support frame and the limiting frame 221 through the limiting block 214 at the bottom of the support frame, so as to drive the lower support assembly 22 to move upward as a whole, thereby reducing the space above the bridge. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0028] During operation, the construction workers first erect the cable tray between the two side slide rails 1, using the slide rails 1 to initially constrain the horizontal displacement of the cable tray. Then, each limiting mechanism 2 is operated one by one: rotating the secondary screw 224 of a single limiting mechanism 2 causes its bottom thread to engage with the groove on the inner wall of the drive block 225. Because the limiting post 227 restricts the rotation of the drive block 225, the drive block 225 moves vertically downwards along the limiting post 227, causing the rack 226 to move synchronously; the rack 226 meshes with the central gear of the support plate 223, driving the support plate 223 to rotate around the connecting shaft 222 to horizontally support the cable tray. Simultaneously, the upper thread of the secondary screw 224 engages with the limiting block 214, pulling the connecting frame 211 upwards along the guide post 215, reducing the distance between the connecting frame 211 and the limiting frame 221, causing the cable tray to partially move upwards. After adjusting all the limiting mechanisms 2 in sequence, the overall support and height adaptation of the cable tray are completed, reducing the space between the cable tray and the installation surface.

[0029] During maintenance, each limiting mechanism 2 is rotated in reverse one by one, with the secondary screw 224 rotating. The drive block 225 moves upward, causing the support plate 223 to rotate and avoid the obstruction. First, operate the limiting mechanism 2 closest to the maintenance area, rotating the secondary screw 224 in reverse at a certain angle. The upper thread of the secondary screw 224 engages with the limiting block 214, increasing the distance between the connecting frame 211 and the limiting frame 221. This limiting mechanism 2 no longer bears the weight of the cable tray, which is then shared by the other limiting mechanisms 2. Next, using the movable connection between the support wheel 213 and the slide rail 1, the limiting mechanism 2 is slid to a non-maintenance area. Then, the secondary screw 224 is rotated in the forward direction to restore its supporting state. The limiting mechanisms 2 are adjusted one by one in this sequence to create operating space for the construction personnel and complete the cable tray maintenance.
