Description

Technical Field

[0001] This utility model belongs to the field of cable reel support technology, specifically a modular cable reel support. Background Technology

[0002] Cable reel supports, also known as cable laying racks or conductor reel racks, are indispensable specialized equipment in the power and communication engineering fields. Their core function is to stably support and accurately fix the cable reel, while providing efficient cable laying assistance for cable laying operations. The current mainstream design adopts a sleeve-type installation structure: the cable reel is sleeved onto a horizontal mounting rod through a central hole. The two ends of the mounting rod are symmetrically supported by two sets of high-load-bearing pulleys, forming a rotatable support system. Through the rolling cooperation between the pulleys and the mounting rod, it ensures low-friction and smooth rotation of the cable reel during the laying process, and the modular design allows for the assembly and disassembly of the mounting rod.

[0003] Utility model patent application publication number 201721370184.6 discloses a cable reel bracket, belonging to the category of bracket equipment. The aim is to provide a cable reel bracket capable of automatically adjusting the height of the rotating shaft. The key technical point is to first measure the diameter of the cable reel to determine which threaded holes (two and one) will mate with it. Then, a servo motor is driven, and the servo motor's rotating rod drives a lead screw to rotate. The lead screw converts the rotational motion into the linear motion of a nut, which in turn drives a lifting rod fixedly connected to the nut to move up and down via a slide rail and groove. Once the lifting rod reaches the correct position, a vertical steel plate and a fixing plate are threadedly connected by bolts. Finally, the cable reel is threaded onto the connecting rod, which is placed in a semi-circular groove. A semi-circular buckle is then fastened, and the connecting piece of the fixing device engages with the fixing block of the semi-circular buckle. The fixing piece presses against the fixing block, thus securing the connecting rod.

[0004] According to the aforementioned patent, there is a cable reel bracket, but it still has shortcomings in actual use. The most obvious one is that the pulleys need to be disassembled, inspected, and maintained after long-term use. The pulleys and U-shaped brackets are usually connected to the movable column by bolts. When the cable reel bracket is in the working environment, water or corrosive liquids can easily enter the gaps between the bolts, accelerating the corrosion of the bolt heads and thread surfaces, and reducing the stability of the cable reel bracket. Therefore, we propose a modular cable reel bracket. Utility Model Content

[0005] The purpose of this invention is to provide a modular cable reel bracket to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Specifically, this application describes a modular cable reel bracket, comprising: a base plate, a mounting frame, and a U-shaped frame. The mounting frame is located above the base plate, and the U-shaped frame is positioned above the mounting frame. Fixed frames are fixedly connected to both ends of the top of the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the scheme of this application:

By rotating the support pulleys of the U-shaped frame and setting the mounting block at the bottom of the U-shaped frame, and by opening a limiting groove on the mounting frame to set the mounting block in the limiting groove, and by rotating the bidirectional screw in the mounting frame, the bidirectional screw drives the moving rods at both ends to move towards each other, and the moving rods drive the limiting block to move into the positioning groove on the mounting block, thereby fixing the U-shaped frame and pulleys. By setting the bidirectional screw in the mounting frame, the impact of water or corrosive liquids on the bidirectional screw can be reduced, ensuring the stability of the cable reel bracket.

[0017] 2. By rotating a threaded rod within a fixed frame and installing a worm gear at the lower end of the threaded rod, and installing a worm gear within the fixed frame to drive the worm gear to rotate, the worm gear drives the worm gear and threaded rod to rotate.

[0026] Please see Figure 1-3 A modular cable reel bracket includes: a base plate 100, a mounting frame 200, and a U-shaped frame 250. The mounting frame 200 is located above the base plate 100, and the U-shaped frame 250 is positioned above the mounting frame 200. The U-shaped frame 250 supports pulleys 251, which are rotatably connected to the U-shaped frame 250 via bearings. Fixed frames 110 are fixedly connected to both ends of the top of the base plate 100, supporting movable columns 150. The movable columns 150 are slidably connected to the inner cavity of the fixed frames 110, driving the mounting frame 200 to move longitudinally. The movable columns 150 are fixedly connected to the mounting frame 200. An adjusting element for driving the longitudinal movement of the movable columns 150 is provided within the fixed frames 110. A limiting groove 210 is formed at the top of the mounting frame 200, for connecting mounting blocks 240. Specifically, a sealing ring can be set at the bottom of the mounting block 240. A bidirectional screw 220 is rotatably connected to one side of the inner cavity of the mounting frame 200. The bidirectional screw 220 is used to drive the moving rod 230 and the limiting block 231 to move. The moving rod 230 is threaded to both ends of the side wall of the bidirectional screw 220. The limiting block 231 is fixedly connected to the facing side of the two sets of moving rods 230. The limiting block 231 limits the mounting block 240 through the limiting groove 210. The bottom of the U-shaped frame 250 is fixedly connected to the mounting block 240 that matches the limiting groove 210. The mounting block 240 is used to support the U-shaped frame 250. The side wall of the mounting block 240 is provided with a positioning groove 241 that matches the limiting block 231. The two ends of the inner side wall of the U-shaped frame 250 are rotatably connected to pulleys 251. The horizontal mounting rod on the cable reel is supported by the two sets of pulleys 251.

[0027] Please see Figure 2The adjusting component includes a threaded rod 130, which is rotatably connected to the bottom of the inner cavity of the fixed frame 110. The threaded rod 130 is threadedly connected to the movable column 150. The fixed frame 110 is provided with a power component that drives the threaded rod 130 to rotate. The rotation of the threaded rod 130 can drive the movable column 150 to move longitudinally.

[0028] Please see Figure 2 The power components include a worm gear 131 and a worm 140. The worm gear 131 is fixedly connected to the lower end of the threaded rod 130, and the worm 140 is rotatably connected to the lower end of the inner side wall of the fixed frame 110. The worm gear 131 and the worm 140 are meshed together. A motor 141 that drives the worm 140 to rotate is fixedly connected to the side wall of the fixed frame 110. The motor 141 drives the worm 140 to rotate, and the worm 140 drives the worm gear 131 and the threaded rod 130 to rotate, so that the threaded rod 130 can self-lock after rotation and fix the position of the movable column 150.

[0029] Please see Figure 2 A partition plate 111 is fixedly connected to the lower end of the inner cavity of the fixed frame 110. The partition plate 111 is rotatably connected to the threaded rod 130, and the worm gear 131 and the movable column 150 are isolated by the partition plate 111.

[0030] Please see Figure 1 The top of the base plate 100 is fixedly connected with a reinforcing rib 120, one end of which is fixedly connected to the fixed frame 110. The stability of the fixed frame 110 is improved by the reinforcing rib 120.

[0031] Please see Figure 3 A rotating block 260 is rotatably connected to the side wall of the mounting frame 200. The rotating block 260 is fixedly connected to the bidirectional screw 220. The bidirectional screw 220 is rotated by the rotating block 260. A hexagonal groove can be opened on one side of the rotating block 260 to facilitate the rotation of the rotating block 260.

[0032] Specifically, in use, the modular cable reel bracket is first connected to a power source. The cable reel is then installed by placing the horizontal mounting rod on the cable reel between two sets of pulleys 251. Next, the motor 141 drives the worm gear 140 to rotate, which in turn drives the worm wheel 131 and the threaded rod 130 to rotate. This allows the threaded rod 130 to self-lock after rotation, fixing the position of the movable column 150. The movable column 150 then drives the mounting frame 200 and the mounting block 240 to move longitudinally. 0 drives the pulley 251 and cable reel to adjust their height. Then, when disassembling the U-shaped frame 250 and the pulley 251, the rotating block 260 drives the bidirectional screw 220 to rotate. The bidirectional screw 220 drives the moving rods 230 at both ends to move towards each other. The moving rods 230 drive the limiting block 231 to move out of the positioning groove 241, so that the mounting block 240 loses its limit. The U-shaped frame 250 then drives the mounting block 240 to move out of the limiting groove 210, thus realizing the disassembly of the U-shaped frame 250 and the pulley 251, and completing the use.
