Description

Technical Field

[0001] This utility model relates to the field of communication tower fall protection technology, specifically a communication tower fall protection device. Background Technology

[0002] Communication towers are a type of signal transmission tower, also called signal transmission towers or signal towers. Their main function is to support signal transmission and provide support for signal transmission antennas. They are used by communication departments such as mobile / China Unicom / traffic satellite positioning systems, etc. Currently, existing communication towers are quite tall. At high altitudes, they are easily damaged by birds and wind, which can cause parts of the towers to fall, resulting in falling objects or accidents during maintenance and repair work.

[0003] In the prior art, Chinese utility model patent CN222045158U discloses a communication tower fall protection device, including an annular guard plate. The annular guard plate has a buffer cavity inside, and a sliding foot is installed in the buffer cavity. A buffer spring is installed between the bottom end of the sliding foot and the buffer cavity. An annular mesh ring is connected to the upper part of the sliding foot. Two layers of rubber bands are installed on the inner side of the annular mesh ring in an up-down arrangement. The inner sides of the two layers of rubber bands are connected to a fixing cover. A receiving mesh is also fixed to the bottom of the annular guard plate by bolts.

[0004] In the aforementioned technology, the device is first fixed to the frame of the communication tower using fixing blocks and external bolts, and the communication tower frame passes through the space between the receiving mesh and the rubber band strip. Then, the opening on the receiving mesh is tightened and fixed, and the device can be put into use. However, since the device is fixed to the communication tower, when workers need to climb it for inspection and maintenance, it cannot be adjusted to the correct position as the workers climb. Therefore, the higher the workers climb, the greater the impact force when they fall, resulting in poor overall protection. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a communication tower fall protection device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fall protection device for a communication tower includes a communication tower body. Mounting plates are fixed to both sides of the communication tower body. A drive motor is fixed to the top of the mounting plates. A lead screw is fixed to the output end of the drive motor. A connecting block is threaded onto the outer wall of the lead screw. A support plate is fixed to one side of the connecting block. A storage frame is fixed to the top of the support plate. An inflatable cushion is placed inside the storage frame. Two air pumps are fixed inside the storage frame. The air outlets of the air pumps are connected and fixed to the bottom of the inflatable cushion. A discharge pipe is connected and fixed to the bottom of the inflatable cushion. An electric valve is installed inside the discharge pipe.

[0008] Preferably, the bottom of the support plate is fixed with multiple fixing blocks, an electric push rod is fixed to one side of each fixing block, a connecting rod is fixed to one side of each electric push rod, and a protective plate is fixed to one end of each connecting rod. The protective plate is made of a material with a certain degree of flexibility.

[0009] Preferably, multiple buzzers are fixed on both sides of the storage frame, and a PLC controller is fixed on both sides of the storage frame, with the buzzers electrically connected to the PLC controller.

[0010] Preferably, a buffer layer is fixed inside the support plate, and the buffer layer is made of rubber.

[0011] Preferably, guide plates are fixed on both sides of the communication tower body, and guide blocks are slidably installed inside the guide plates, with one side of the guide block being fixedly connected to one side of the support plate.

[0012] Preferably, the connecting rod is U-shaped and made of corrosion-resistant material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The output of the drive motor rotates, causing the lead screw to rotate, which in turn moves the connecting block up and down. This drives the support plate to move up and down, allowing the storage frame to move upwards with the worker, thus shortening the distance between the storage frame and the worker. Before this, the connecting rod is moved by the telescopic end of the electric push rod, allowing the protective plate to be removed. Then, the air pump starts running, causing the air cushion to inflate. Therefore, by adjusting the distance between the air cushion and the worker, the impact force when the worker falls in the event of an accident can be reduced, thereby improving safety and protection, and reducing the risk of injury. After use, the air in the air cushion is discharged through the discharge pipe, returning it to the inside of the storage frame. The protective plate is then moved above the storage frame, preventing damage to the air cushion. When there are no workers present, the protective plate can prevent some parts from falling, thus improving practicality. Attached Figure Description

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a communication tower fall protection device, including a communication tower body 1, mounting plates 2 fixed on both sides of the communication tower body 1, a drive motor 3 fixed on the top of the mounting plate 2, a lead screw 4 fixed on the output end of the drive motor 3, a connecting block 5 threaded to the outer wall of the lead screw 4, a support plate 6 fixed on one side of the connecting block 5, a storage frame 7 fixed on the top of the support plate 6, an inflatable cushion 8 placed inside the storage frame 7, two air pumps 9 fixed inside the storage frame 7, the air outlets of the air pumps 9 connected and fixed to the bottom of the inflatable cushion 8, a discharge pipe 10 connected and fixed to the bottom of the inflatable cushion 8, and an electric valve installed inside the discharge pipe 10;

[0021] Multiple fixing blocks 11 are fixed to the bottom of the support plate 6. An electric push rod 12 is fixed to one side of the fixing block 11. A connecting rod 13 is fixed to one side of the electric push rod 12. A protective plate 14 is fixed to one end of the connecting rod 13. The material of the protective plate 14 has a certain degree of flexibility.

[0022] In this invention, the output of the drive motor 3 rotates, causing the lead screw 4 to rotate, which in turn moves the connecting block 5 up and down. This drives the support plate 6 to move up and down, thus moving the storage frame 7 upwards with the worker, shortening the distance between it and the worker. Before this, the extension end of the electric push rod 12 moves the connecting rod 13, allowing the protective plate 14 to be removed. Then, the air pump 9 starts running, causing the air cushion 8 to inflate. By adjusting the distance between the air cushion 8 and the worker, the impact force when the worker falls in an accident is reduced, thus improving safety and protection and reducing the risk of injury. After use, the air in the air cushion 8 is discharged through the discharge pipe 10, returning it to the inside of the storage frame 7. The protective plate 14 is then moved above the storage frame 7 to prevent damage to the air cushion 8. When there are no workers, the protective plate 14 can prevent some parts from falling, thus improving practicality.

[0023] More specifically, multiple buzzers 15 are fixed on both sides of the storage frame 7, and PLC controllers 16 are fixed on both sides of the storage frame 7. The buzzers 15 and PLC controllers 16 are electrically connected. A buffer layer 17 is fixed inside the support plate 6. The buffer layer 17 is made of rubber. Guide plates 18 are fixed on both sides of the communication tower body 1. A guide block 19 is slidably installed inside the guide plate 18. One side of the guide block 19 is fixedly connected to one side of the support plate 6. The connecting rod 13 is U-shaped and made of corrosion-resistant material.

[0024] In this invention, a buzzer 15 sounds an alarm, promptly alerting those nearby when someone falls, allowing for timely rescue. The buffer plate 17 reduces impact and improves stability. The sliding of the guide block 19 within the guide plate 18 ensures smoother movement of the support plate 6, preventing tilting and enhancing protection. The corrosion-resistant material extends service life and facilitates smoother movement of the protective plate 14, preventing it from becoming impossible to open.

[0025] Working principle: When workers are inspecting and maintaining the communication tower body 1, as they climb upwards, the output end of the drive motor 3 rotates, driving the lead screw 4 to rotate, which in turn moves the connecting block 5 up and down. This drives the support plate 6 to move up and down, causing the storage frame 7 to move upwards with the workers, thus shortening the distance between the storage frame 7 and the workers. Before this, the extension end of the electric push rod 12 moves the connecting rod 13, which can remove the protective plate 14. Then, the air pump 9 starts running, causing the air cushion 8 to inflate. By adjusting the distance between the air cushion 8 and the workers, the impact force when the workers fall in case of an accident can be reduced, thereby improving safety and protection and reducing the risk of injury. After use, the air in the air cushion 8 is discharged through the discharge pipe 10, thus returning it to the inside of the storage frame 7. The protective plate 14 is then moved above the storage frame 7 to prevent damage to the air cushion 8. When there are no workers, the protective plate 14 can prevent some parts from falling down, thus improving practicality.
