Description

Technical Field

[0001] This utility model relates to the field of suspended platform technology, and in particular to a device for preventing the lower anchor rod tie line from loosening. Background Technology

[0002] A suspended platform is a temporary, liftable platform suspended from the exterior of a building or structure to carry personnel and tools for high-altitude operations. It functions like an "aerial workstation" and is widely used in building exterior construction, cleaning, and maintenance. However, during dynamic high-altitude operations, if the hoist fails or the suspension mechanism malfunctions, and without proper protection, the personnel and equipment inside the platform face imminent danger. Furthermore, under the influence of wind, mechanical vibration, or improper operation, if the suspended platform is not securely fastened to a reliable structure (such as guy wires) to prevent detachment, it may violently sway, loosen, or even collide with the building, endangering personnel safety and causing property damage.

[0003] In existing technologies, the installation position adjustment of traditional anti-loosening devices is extremely inconvenient. Their support span is fixed, making it difficult to flexibly adapt to different roof structures or work surface requirements. As a result, the stability of the suspended platform largely depends on the operator's experience and limited site conditions, leaving huge safety uncertainties. Therefore, we propose a lower anchor rod and tie line anti-loosening device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a device to prevent the anchor rod and tie line from loosening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-loosening device for a lower anchor rod includes a flagpole. Two U-shaped components are fixedly embedded in the outer wall of the flagpole. U-shaped components are fixedly connected to the inner walls of the two U-shaped components. A support rod and a crossbar are slidably connected to the inner walls of the two U-shaped components, respectively. A traction wheel is rotatably connected to the top of the flagpole and one end of the support rod. Two second I-shaped components are rotatably connected to the outer wall of the support rod. A first I-shaped component and a pull rod are rotatably connected to the outer wall of the support rod. An anchor plate is rotatably connected to the bottom of the pull rod. Two ear plates are fixedly connected to the outer wall of the anchor plate. A rope puller is rotatably connected to both the ear plates and the outer wall of the first I-shaped component. Steel wire ropes are sleeved on the outer walls of the three rope pullers. One end of two steel wire ropes is fixedly connected to the outer walls of the two second I-shaped components, respectively. A limiting component is provided on the outer wall of the crossbar.

[0007] Preferably, the limiting component includes two mounting plates. The outer walls of both mounting plates are provided with rectangular grooves. The inner walls of the two rectangular grooves are slidably connected to the outer wall of the crossbar. The outer walls of both mounting plates are provided with threaded holes. The inner walls of the two threaded holes are threaded with hand-tightening screws. One end of each hand-tightening screw is rotatably connected to a metal disc. The outer walls of both mounting plates are provided with mating holes. The metal disc and the rubber pad on the outer wall are pressed against the side of the structural beam. With the help of the anchor plate, the flagpole can be fixed in position.

[0008] Preferably, the outer walls of the two U-shaped parts, the support rod, and the crossbar are provided with multiple insertion holes, and the inner walls of four of the insertion holes are slidably connected with pins.

[0009] Preferably, the outer wall of the anchor plate is provided with multiple anchor holes, which are used to fix the anchor plate to the roof plane with anchor bolts.

[0010] Preferably, one end of the other wire rope is slidably connected to the outer wall of both traction wheels.

[0011] Preferably, rubber pads are fixedly connected to the outer walls of both metal discs.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution allows for adjustment of the limit components via a rotating hand-tightening screw, adapting to roof beams or stable structures of different sizes. No special fixing parts are required. The mounting plate position can be flexibly adjusted using multiple insertion holes. Combined with the telescopic and crossbar extension and pin positioning, the span of the support can be changed according to the roof structure or work surface requirements, making it more adaptable. The anchor plate is fixed to the roof plane with anchor bolts. The pull rod, support rod, wire rope and flagpole together form a triangular support system, resulting in more balanced structural stress and improved anti-overturning ability.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a device for preventing loosening of the anchor rod and guy wire is disclosed, comprising a flagpole 1. Two U-shaped parts 2 are fixedly embedded in the outer wall of the flagpole 1. U-shaped parts 3 are fixedly connected to the inner walls of the two U-shaped parts 2. Support rods 4 and crossbars 5 are slidably connected to the inner walls of the two U-shaped parts 3 respectively. Multiple insertion holes 6 are provided on the outer walls of the two U-shaped parts 3, the support rods 4, and the crossbars 5. Pins are slidably connected to the inner walls of four of the insertion holes 6. The support rods 4 and the crossbars 5 slide on the inner walls of the U-shaped parts 3 respectively. The pins are inserted into the corresponding insertion holes 6 for positioning. The extension length of the support rods 4 and the crossbars 5 can be flexibly changed, thereby adjusting the span of the support and adapting to different roof structures and working surface requirements.

[0021] The top of the flagpole 1 and one end of the support pole 4 are rotatably connected to a traction wheel 7 via an existing shaft. The outer wall of the support pole 4 is rotatably connected to two second I-shaped parts 9 via an existing shaft. The outer wall of the support pole 4 is rotatably connected to a first I-shaped part 8 and a pull rod 10 via an existing shaft. The bottom of the pull rod 10 is rotatably connected to an anchor plate 11 via an existing shaft. The outer wall of the anchor plate 11 has multiple anchor holes. The anchor plate 11 is fixed to the roof plane with anchor bolts through the multiple anchor holes on the outer wall. The pull rod 10 rotatably connected to its top forms a triangular support system with the flagpole 1 and the support pole 4.

[0022] Two ear plates 12 are fixedly connected to the outer wall of the anchor plate 11. Both ear plates 12 and the outer wall of the first I-shaped part 8 are rotatably connected to a rope puller 13 via an existing shaft. The outer walls of the three rope pullers 13 are all fitted with steel wire ropes 14. One end of two steel wire ropes 14 is fixedly connected to the outer walls of the two second I-shaped parts 9 respectively, and one end of the other steel wire rope 14 is slidably connected to the outer walls of the two traction wheels 7. The first I-shaped part 8 and the ear plates 12 on the outer wall of the support rod 4 provide rotational support for the rope pullers 13, ensuring that the rope pullers 13 can flexibly adjust their angle when tightening the steel wire ropes 14, thus ensuring stable tension transmission.

[0023] The outer wall of the crossbar 5 is equipped with a limiting component, which includes two mounting plates 15. The outer wall of each mounting plate 15 has a rectangular groove, and the inner wall of each rectangular groove is slidably connected to the outer wall of the crossbar 5. The outer wall of each mounting plate 15 has a threaded hole, and the inner wall of each threaded hole is threaded with a hand-tightening screw 16. One end of each hand-tightening screw 16 is rotatably connected to a metal disc 17 via an existing shaft. The outer wall of each mounting plate 15 has a mating hole, and the mounting plate 15 is fixed in position by inserting a pin into the mating hole and the insertion hole 6. The outer wall of each metal disc 17 is fixedly connected with a rubber pad 18. Rotating the hand-tightening screw 16 in the threaded hole of the mounting plate 15 can drive the metal disc 17 and the rubber pad 18 on the outer wall to press against the side of the structural beam. It can be adapted to roof beams or stable structures of different sizes without special accessories, making installation and adjustment more convenient.

[0024] Working principle: During use, the flagpole 1 is securely installed on the roof beam or other stable structure through its limiting components. This process is achieved by rotating the hand-tightening screw 16, which drives the metal disc 17 and rubber pad 18 to press tightly against the side of the structural beam, thereby reliably fixing the flagpole 1 in the working position. The positions of the two mounting plates 15 can be adjusted according to the positions of the multiple insertion holes 6. Subsequently, by adjusting the extension length of the support rod 4 and the crossbar 5 and inserting the pin shaft for positioning, a stable external support is formed. The anchor plate 11 is fixed to the lower side of the structural beam through components such as anchor bolts and anchor holes. The pull rod 10, together with the support rod 4, the wire rope 14 and the flagpole 1, form a stable triangular support system. Finally, the wire rope 14 passes around the traction wheel 7, one end is tightened and fixed by the rope puller 13, and the other end is used to connect and suspend the basket. This tensioned wire rope 14 provides reliable anti-loosening and anti-sway protection for the basket.
