Abstract
Description
Technical Field
[0001] This utility model relates to the field of power tower maintenance and protection technology, and in particular to a tower climbing protection safety control device. Background Technology
[0002] Safety fall arrestors for power tower maintenance are crucial equipment for ensuring the safety of power maintenance personnel during tower climbing operations. In the power industry, the maintenance and repair of power towers is of paramount importance, requiring workers to frequently climb towers. However, traditional fall arrestors have several drawbacks. Firstly, their protective mechanisms often rely on relatively simple mechanical structures, making it difficult to provide comprehensive safety in complex tower climbing scenarios. For example, if a person accidentally falls, traditional devices may not be able to quickly and effectively lock the safety rope, leading to a fall accident. Secondly, traditional devices lack intelligent management tools, failing to monitor the personnel's working status in real time or provide timely warnings of potential safety hazards. This makes it difficult for managers to keep track of the operational dynamics, resulting in low safety and management efficiency.
[0003] Therefore, this technology proposes a tower climbing safety control device. Through a multi-component collaborative safety protection design, the device utilizes the gravity generated by a person falling to drive the safety rope, causing the winch to rotate at high speed. Using centrifugal force and a torsion spring, the pawl and inner ratchet engage quickly, locking the safety rope and preventing falls. Simultaneously, it is equipped with an intelligent sensing and remote monitoring system to achieve intelligent management and efficient supervision of tower climbing operations. After the worker inserts the safety buckle into the sensing device, the device senses the distance in real time and automatically controls the motor to adjust the safety rope's extension and retraction, reducing manual operation and improving operational convenience and safety. Once an abnormality is detected, the backend immediately issues an alarm, allowing managers to monitor the operation in real time. This achieves comprehensive tower climbing safety assurance and intelligent management of tower climbing operations, greatly improving operational safety and management efficiency. Utility Model Content
[0004] The technical problems to be solved are: the lack of a single protection mechanism and the lack of intelligent management methods.
[0005] To achieve the above objectives, this utility model proposes a tower climbing protection safety control device, including a steel tower, wherein a fall protection component and an extension component are installed at the top of the steel tower via a bracket assembly;
[0006] The fall arrestor includes a mounting plate, which is connected to the tower via a bracket assembly. An equipment box is mounted on the front of the mounting plate, and a winch is rotatably connected inside the equipment box. A motor is installed inside the equipment box, and the motor is located inside the winch. Gear 1 is fixedly connected to the output end of the motor. Gear 2 is installed inside the equipment box. An internal gear 3 is installed on the side of the winch near the output end of motor 1. Gear 1 meshes with gear 2, and gear 2 meshes with internal gear 3. A safety rope is fixedly connected to the outside of the winch.
[0007] The equipment box is equipped with a sensing device, and the safety rope is equipped with a pin-type sensing device at the end.
[0008] Two pawls are rotatably connected to the side of the winch away from the internal gear three. A torsion spring is fitted at the rotatable connection between the two pawls and the winch. An internal ratchet is installed inside the equipment box at the rotatable connection with the winch, and the internal ratchet is fitted on the outside of the pawls.
[0009] In one example, the sensor is activated by inserting the safety buckle of the worker's safety belt into the sensor's socket. The sensor controls the motor to start by sensing the distance between itself and the sensor in real time; when the distance is close, the motor retracts, and when the distance is far, the motor extends.
[0010] In one example, the centrifugal force of the two pawls rotating counterclockwise is greater than the rebound force of the torsion spring.
[0011] In one example, the extension assembly is mounted on the front side of the mounting plate and includes a folding plate rotatably connected to the front side of the mounting plate. Two electric actuators are mounted on the front side of the mounting plate, with the output ends of the electric actuators connected to the end of the folding plate away from the mounting plate. A folding arm is mounted on the upper side of the folding plate, with a bidirectional threaded rod threadedly connected to the end of the folding arm near the folding plate. A second motor is mounted on the lower side of the folding plate, and a pulley assembly is installed between the output end of the second motor and one end of the bidirectional threaded rod.
[0012] In one example, the support assembly includes two hanging rods and two side rods. The hanging rods and side rods are connected in a "well" shape by bolts. The upper end of the hanging rod can be hung on the iron tower and fixed by bolted clamps. The two sides of the side rod are hung on the iron tower by bolted side hanging plates. Bolt grooves are provided at the top of the hanging rod and in the middle of the side rod.
[0013] In one example, the support assembly is equipped with a monitoring system that is connected in real time to a back-end management center. When the monitoring system detects that someone is climbing the tower and no sensors are detected, the back-end management center issues an alarm to check the situation on site and take appropriate action.
[0014] In one example, the end of the folding arm away from the bidirectional threaded rod is rotatably connected to a pulley.
[0015] The tower climbing protection and safety control device proposed in this utility model has the following beneficial effects:
[0016] 1. In this utility model, through the multi-component collaborative safety protection design, all-round tower climbing safety protection is achieved. In the fall protection component, the gravity generated by the fall of personnel will drive the safety rope to rotate counterclockwise at high speed. When the winch rotates at a high speed, its centrifugal force is greater than the rebound force of the torsion spring. The pawl will open outward in the direction of the winch rotation. When it contacts the inner ratchet, the pawl and the inner ratchet engage, thereby restricting the rotation of the winch and thus quickly locking the safety rope, thereby preventing personnel from falling.
[0017] 2. This utility model utilizes an intelligent sensing and remote monitoring system to achieve intelligent management and efficient supervision of tower climbing operations. After the worker inserts the safety buckle into the sensing device, the device detects the distance between them in real time and automatically controls the motor to adjust the safety rope's extension and retraction, adapting to different needs of climbing or descending, reducing manual operation, and improving operational convenience and safety. Simultaneously, the monitoring system is connected to the back-end management center in real time. If a worker is detected climbing the tower but the sensing device is not activated, the back-end immediately issues an alarm. Workers can then view the situation on-site and take appropriate action. This not only allows for the timely detection of potential safety hazards but also facilitates real-time monitoring of the operational dynamics by management personnel, enabling intelligent management of the entire tower climbing process and improving operational safety and management efficiency.

Detailed Implementation
[0025] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0026] like Figures 1-5 As shown, an embodiment of this utility model proposes a tower climbing safety control device, which includes a tower 1 and a fall arrestor 3 and an extension component 4 installed on the tower 1 via a support assembly 2. It also includes a monitoring device 5 installed on the support assembly 2. The support assembly 2 serves to install the fall arrestor 3 and the monitoring device 5. The extension component 4 is used to extend the safety rope 311. The monitoring device 5 is used for daily inspection and personnel monitoring.
[0027] The support assembly 2 includes two hanging rods 201 and two side rods 202. The hanging rods 201 and the side rods 202 are connected in a "well" shape by bolts. The upper end of the hanging rod 201 can be hung on the iron tower 1. The hook is connected to the clamp plate 203 by bolts. The clamp plate 203 can fix the hanging rod 201 to the iron tower 1. Both sides of the side rod 202 are connected to the side hanging plate 204 by bolts. The side hanging plate 204 has a hook-shaped design and can be hung on both sides of the iron tower 1. It is fixed by bolts so that it can be connected to the iron tower 1. The top of the hanging rod 201 and the middle of the side rod 202 are provided with bolt grooves 205. The position of the bolt can be adjusted by bolt grooves 205, thereby making the connection between the support assembly 2 and the iron tower 1 more secure.
[0028] Fall arrestor assembly 3 includes mounting plate 301, which is connected to tower 1 via bracket assembly 2. Equipment box 302 is mounted on the front of mounting plate 301. Winch 303 is rotatably connected inside equipment box 302. Motor 304 is installed inside equipment box 302 and located inside winch 303. Gear 305 is fixedly connected to the output end of motor 304. Gear 306 is installed inside equipment box 302. Winch 303 is located near the output of motor 304. An internal gear 307 is installed on one side of the end. Gear 1 305 meshes with gear 2 306, and gear 2 306 meshes with internal gear 307. Motor 1 304 drives gear 1 305 and then drives internal gear 307 to rotate through gear 2 306. Internal gear 307 causes winch 303 to rotate inside equipment box 302. A safety rope 311 is fixedly connected to the outside of winch 303. The rotation of winch 303 realizes the raising and lowering of safety rope 311.
[0029] Two pawls 308 are rotatably connected to the side of the winch 303 away from the internal gear 307. Torsion springs 309 are fitted at the rotatable connection points of the two pawls 308 and the winch 303. The rebound force of the torsion springs 309 pushes the pawls 308 to fold inward. An inner ratchet 310 is installed inside the equipment box 302 at the rotatable connection point of the winch 303. The inner ratchet 310 is fitted over the pawls 308. When a person falls, the person is connected to the safety rope 311, which causes the winch 303 to rotate counterclockwise at high speed. When the winch 303 rotates at a high speed, its centrifugal force is greater than the rebound force of the torsion springs 309. The pawls 308 open outward in the direction of the winch 303's rotation. When they contact the inner ratchet 310, the pawls 308 engage with the inner ratchet 310, thus restricting the rotation of the winch 303 and quickly locking the safety rope 311, thereby preventing a fall.
[0030] An extension assembly 4 is installed on the front side of the mounting plate 301. Since the iron tower 1 is generally narrower at the top and thicker at the bottom, if the safety rope 311 falls naturally from the top of the iron tower 1 under gravity, it may be obstructed by the iron tower 1, preventing it from falling properly. Therefore, the extension assembly 4 can push the safety rope 311 a certain distance outward from the iron tower 1, thus avoiding the influence of the iron tower 1. Specifically, it includes a folding plate 401 rotatably connected to the front side of the mounting plate 301. Two electric actuators 402 are installed on the front side of the mounting plate 301. The output ends of both electric actuators 402 are connected to the end of the folding plate 401 furthest from the mounting plate 301. The upper part of the folding plate 401... A folding arm 403 is installed on the side. The end of the folding arm 403 near the folding plate 401 is threaded with a bidirectional threaded rod 404. A second motor 405 is installed on the lower side of the folding plate 401. A pulley set 406 is installed between the output end of the second motor 405 and one end of the bidirectional threaded rod 404. The second motor 405 drives the pulley set 406, which in turn drives the bidirectional threaded rod 404 to rotate. The forward and reverse rotation of the bidirectional threaded rod 404 realizes the extension and retraction of the folding arm 403. A pulley 407 is rotatably connected to the end of the folding arm 403 away from the bidirectional threaded rod 404. The pulley 407 plays the role of making the safety rope 311 fall more smoothly.
[0031] The equipment box 302 is equipped with a sensor 6, and the end of the safety rope 311 is equipped with a sensor 7. The sensor 7 is a pin-type design. When the safety buckle on the worker's body is inserted into the socket on the sensor 7, the sensor 7 is triggered to open. After the sensor 7 is opened, the sensor 6 can sense the distance between the sensor 6 and the sensor 7 in real time. When the worker climbs the iron tower 1, the sensor 7 will rise with him, and the distance between the sensor 6 and the sensor 7 will become shorter and shorter. At this time, the sensor 6 will open the motor 304 according to the distance between it and the sensor 7, and then adjust the rotation of the winch 303 to raise and lower the safety rope 311. When the distance is close, it will be raised; when the distance is far, it will be lowered.
[0032] In summary, the specific implementation is as follows:
[0033] 1. Equipment Installation and Preparation
[0034] Hang the hooks at the upper ends of the two hanging rods 201 of the support assembly 2 on the iron tower 1, and fix the hanging rods 201 on the iron tower 1 by bolting the clamp plate 203; at the same time, hook the side hanging plates 204 on both sides of the side rod 202 on both sides of the iron tower 1 and fix them with bolts. Adjust the position of the bolts in the bolt groove 205 at the top of the hanging rod 201 and the middle of the side rod 202 to make the connection between the support assembly 2 and the iron tower 1 more secure and ensure that the entire device is stably installed on the iron tower 1.
[0035] Confirm that the fall arrestor assembly 3, extension assembly 4, and monitoring equipment 5 are correctly installed on the support assembly 2. Check whether the connections of components such as winch 303, motor 1 304, gear 1 305, gear 2 306, and internal gear 3 307 in the fall arrestor assembly 3 are secure, and whether the safety rope 311 is damaged. Check whether the components such as folding plate 401, electric push rod 402, folding arm 403, bidirectional threaded rod 404, motor 2 405, and pulley 407 in the extension assembly 4 are normal. Check whether the power connections of each component are normal and whether the monitoring equipment 5 can work normally.
[0036] 2. Preparation for lowering safety rope 311
[0037] The operator turns on the Bluetooth on their mobile phone and the accompanying APP at the foot of the tower. The device automatically searches for and pairs with the fall protection device via Bluetooth. After successful pairing, the operator gains control of the fall protection device.
[0038] Lowering the safety rope 311 and opening the folding arm 403: Operated via the APP, the motor 1 304 is started, which drives the gear 1 305, which in turn drives the gear 2 306, and finally drives the internal gear 3 307 to rotate. The internal gear 3 307 causes the winch 303 to rotate inside the equipment box 302. The rotation of the winch 303 lowers the safety rope 311. During the lowering process, the electric push rod 402 is started. The electric push rod 402 first retracts, and during the retraction process, it raises the folding plate 401 to be perpendicular to the mounting plate 301, thereby making the extension direction of the folding arm 403 perpendicular to the tower 1.
[0039] Then, the second motor 405 starts and drives the pulley group 406 to rotate the double-threaded rod 404. The rotation of the double-threaded rod 404 pushes the extension of the folding arm 403. The extension of the folding arm 403 pushes the safety rope 311 outward to the outside of the tower 1, thereby preventing the hammer from falling into the tower body during the descent.
[0040] 3. Safety rope 311 attachment and ascent
[0041] After the end of the safety rope 311 descends to the bottom, the inspection personnel insert the safety buckle on their body into the socket on the sensor device 7, triggering the sensor device 7 to open.
[0042] Then the tower climbing work can begin. As the inspection personnel continue to ascend, the distance between the sensor device 7 and the sensing device 6 gets closer and closer. At this time, the sensing device 6 controls the motor 1 304 to start. The output end of the motor 1 304 drives the gear 1 305 to rotate. The gear 1 305 meshes with the gear 2 306. The gear 2 306 drives the internal gear 3 307 to rotate, thereby causing the winch 303 to rotate clockwise in the equipment box 302 and retract the safety rope 311.
[0043] 4. Emergency Handling
[0044] As the winch 303 rotates inside the equipment box 302, the safety rope 311 is retracted. When the inspection personnel suddenly fall, the safety rope 311 will cause the winch 303 to rotate counterclockwise at high speed. When the winch 303 rotates at a high speed, its centrifugal force is greater than the rebound force of the torsion spring 309. The pawl 308 will open outward in the direction of the winch 303's rotation. When it contacts the inner ratchet 310, the pawl 308 engages with the inner ratchet 310, thereby restricting the rotation of the winch 303 and quickly locking the safety rope 311 to prevent personnel from falling. Rescue work can then be carried out.
[0045] 5. The descent and retrieval of safety rope 311
[0046] After the inspection work is completed, the inspection personnel climb down. As the inspection personnel continue to descend, the distance between the sensor 7 and the sensing device 6 becomes farther and farther. At this time, the sensing device 6 controls the motor 304 to start. The motor 304 drives the winch 303 to rotate counterclockwise in the equipment box 302 through a series of transmissions. At this time, because the winch 303 rotates slowly, the centrifugal force of its pawl 308 is less than the rebound force of the torsion spring 309, so that the pawl 308 cannot open, thereby preventing the winch 303 from locking up when the personnel are descending.
[0047] When the inspection personnel return to the ground, they unconnect the safety buckle to the connector on the sensor 7. At this time, the sensing between the sensor 7 and the sensing device 6 is turned off. The motor 304 is started by controlling the APP, and the safety rope 311 can be retrieved.
[0048] 6. Work process monitoring
[0049] During high-altitude operations, monitoring device 5 will monitor personnel in real time. Monitoring device 5 is connected to the back-end management center in real time. When it detects that someone is climbing tower 1 and no sensor device 6 is detected to be working, the back-end management will issue an alarm. The site can be viewed again through monitoring device 5, and then the handling work can be carried out.
