Technical Field
[0001] This utility model belongs to the field of high-altitude operation safety protection technology, specifically an adjustable safety protection device suitable for high-altitude operations. Background Technology
[0002] In the field of high-altitude operations, the performance of safety protection devices is directly related to the life safety of construction workers and work efficiency. At present, high-altitude operation protection devices are widely used in many industries such as construction, power, and wind power. However, most of these devices adopt fixed structures or single-function designs, which makes it difficult to make flexible adjustments according to different working environments, resulting in limited applicability and inability to fully meet complex and ever-changing construction needs.
[0003] For example, a Chinese invention patent (patent number: CN112431398B) discloses a protective frame and a safety protection device for high-altitude operations. Its description includes a first frame through which a construction platform is erected on a steel structure. The structure is simple and low-cost, applicable to steel structures of any shape, with no blind spots, facilitating construction. However, the protective frame in this design is a fixed installation structure, lacking adjustability and making it difficult to dynamically adjust according to different heights and angles of operation, thus limiting its flexibility in various working conditions. Furthermore, the device lacks an automatic locking or emergency braking mechanism, which may prevent timely and effective protection in emergencies, posing a certain safety hazard.
[0004] For example, a Chinese invention patent (patent number: CN117142288B) discloses a protective device for high-altitude operations in wind power generation. Its description states that the friction between the brake block and the guide rail enables emergency braking of the work platform to prevent uncontrolled falls. Simultaneously, rollers monitor the moving speed, and when it exceeds the expected value, feedback is sent to the control system to bring it to a stop, thereby maximizing the safety of maintenance personnel. However, this device still has certain limitations: First, its protection range is fixed and cannot be expanded or contracted according to changes in the work area, resulting in poor adaptability. Second, the device relies on electronic monitoring equipment for control; if the system malfunctions or the signal is interrupted, the emergency braking may fail, and its reliability needs improvement. Furthermore, the device does not consider the ergonomic support issues for workers during prolonged high-altitude operations, lacking comfort and adjustability design.
[0005] The aforementioned problems indicate that current high-altitude work safety devices on the market still have certain limitations in terms of structural flexibility, intelligent response capabilities, and ergonomic design, making it difficult to fully meet the comprehensive requirements of modern high-altitude operations for safety, adaptability, and ease of operation. Therefore, this invention proposes an adjustable safety protection device suitable for high-altitude operations to overcome the shortcomings of existing technologies, such as non-adjustable protective structures, untimely response, and poor adaptability, thereby improving the safety and efficiency of high-altitude operations.

The support adjustment module 1 consists of multiple telescopic connecting units, its main components being two symmetrically arranged telescopic rods 4 and a crossbeam 5 connecting them. Locking bolts are provided on the outer side of the telescopic rods 4, penetrating the outer wall of the telescopic rods 4 and fixing their length by tightening. Through holes are provided at both ends of the crossbeam 5, with bearings 6 embedded within them. The inner ring of the bearings 6 is fixedly connected to the top of the telescopic rods 4, allowing the crossbeam 5 to rotate smoothly on the telescopic rods 4. A connecting seat is fixedly provided in the middle of the crossbeam 5, with sliding grooves on both sides of the connecting seat. Sliding blocks are installed in the sliding grooves, and these sliding blocks are connected to the upper part of the balance and stabilization module 2. This design ensures the flexibility of the support adjustment module 1 when adjusting height and angle. To prevent safety hazards caused by excessive extension and retraction of the telescopic rods 4, a limiting pin 7 is inserted into the outer wall of the telescopic rods 4, with a rubber sleeve at the end of the limiting pin 7 to prevent scratches to workers.
[0029] Balanced stabilization module 2, such as Figure 3As shown, it includes a base 8 and multiple legs 9. The top of the base 8 has a boss whose shape matches the bottom of the slider, and the two are fixed together by a threaded connection.

The surface of the armrest 15 is covered with an anti-slip sleeve, which is formed on the outside of the armrest 15 by injection molding to improve the stability of gripping.
[0031] Lighting components such as Figure 5 As shown, it includes a lamp holder 16 and an LED light 17. The lamp holder 16 is fixed to the bottom of the crossbeam 5 by bolts, and the LED light 17 is embedded inside the lamp holder 16. A switch button 18 is provided on the side of the lamp holder 16. The switch button 18 is electrically connected to the LED light 17 through a wire and is used to control the lighting function. The arrangement of the lighting components ensures that workers have sufficient light source at night or in low-light environments.
[0032] The operating principle of this utility model is as follows: When workers need to perform high-altitude operations, they first adjust the height and angle of the support adjustment module 1 according to the working height and angle. Specifically, this is done by loosening the locking bolts on the telescopic rod 4, adjusting the length of the telescopic rod 4, and limiting the extension range of the telescopic rod 4 by the limit pin 7. The crossbeam 5 is connected to the telescopic rod 4 through the bearing 6, allowing the crossbeam 5 to rotate flexibly. Subsequently, the outriggers 9 of the balance stabilization module 2 are adjusted to adapt to different terrain conditions. The spring design of the outriggers 9 can automatically adapt to uneven ground, and the anti-slip pad 10 further improves the friction between the device and the ground. The storage cavity 11 inside the base 8 can be used to store tools or emergency rescue equipment, improving the practicality of the device. Next, workers can adjust the angle of the seat 12 of the ergonomic auxiliary module 3 according to their personal needs by rotating the knob. The flexible pad of the backrest assembly 13 and the armrests 15 significantly improve the comfort and ease of operation for workers, while the hydraulic damping device of the shock absorber 14 effectively reduces vibration and impact during high-altitude operations. Finally, the LED light 17 is turned on by pressing the switch button 18 on the lamp holder 16 to provide lighting for the work area.
[0033] The various modules of this invention achieve synergistic effects through reasonable connection and positional relationships, solving the problems of fixed structure, poor adaptability, and lack of comfort and safety guarantees in existing high-altitude work protection devices. To better enable those skilled in the art to fully understand and implement this invention, the following supplementary explanation of its implementation principles is provided in conjunction with specific application scenarios.
[0034] In high-altitude work scenarios, such as external maintenance of wind turbine towers, workers need to complete maintenance tasks at different heights and angles. First, the worker must place the device on the tower platform or other stable location and adjust the height and angle of the support adjustment module 1 according to actual needs. By loosening the locking bolts on the telescopic rod 4, the worker can manually pull the telescopic rod 4 to extend it from its initial length to the required height. During this process, the limiting pin 7 plays a crucial role; its end rubber sleeve not only prevents scratches to the operator but also limits the maximum extension range of the telescopic rod 4, avoiding structural damage or safety hazards due to overstretching. Once the telescopic rod 4 is adjusted to the appropriate height, the locking bolts are tightened to fix its length. The crossbeam 5 is connected to the telescopic rod 4 via bearings 6, ensuring that the crossbeam 5 can rotate flexibly in the horizontal direction, thus adapting to different angle work requirements.
[0035] Subsequently, the balancing and stabilizing module 2 enters its working state. Operators need to place the base 8 on the ground or platform and adjust the outriggers 9 to adapt to uneven terrain. Each outrigger 9 consists of two sleeves, with a spring design between the sleeves that automatically compresses or extends to match changes in ground elevation. Anti-slip pads 10 further enhance the friction between the device and the ground, effectively preventing the device from sliding or tipping over. Notably, the scale on the outer wall of the outriggers 9 is coated with a fluorescent coating, allowing for clear reading even in low-light conditions and facilitating quick adjustment of the outrigger length. Furthermore, the storage cavity 11 inside the base 8 provides additional storage space for operators, which can be used to store tools, emergency rescue equipment, and other items, enhancing the device's practicality.
[0036] Next, the ergonomic auxiliary module 3 comes into play. Operators can adjust the angle of the seat 12 according to their individual needs by rotating a knob to rotate the pivot, allowing the seat 12 to rotate around the hinge point at the top of the connecting seat to the desired position. The flexible pad in the backrest assembly 13 is attached to the support plate surface with Velcro, facilitating easy removal, cleaning, or replacement, ensuring hygienic conditions for long-term use. Simultaneously, the hydraulic damping device within the shock absorber 14 is connected to an external pressure regulating valve via an oil circuit. Operators can adjust the hydraulic damping force by adjusting the valve, thereby mitigating vibration and impact during high-altitude work and improving comfort. The anti-slip sleeves covering the surface of the armrests 15 are injection molded, not only improving grip stability but also reducing fatigue from prolonged operation.
[0037] Finally, the lighting assembly provides support for operations at night or in low-light environments. When the work area is poorly lit, the operator presses the switch button 18 on the side of the lamp holder 16, and the wire transmits an electrical signal to the LED light 17, illuminating the work area. The lamp holder 16 is fixed to the bottom of the crossbeam 5 with bolts, ensuring that the lighting assembly remains stable and does not shake due to device movement.
[0038] In summary, this utility model achieves adjustable height and angle, strong terrain adaptability, and optimized ergonomics through the synergistic effect of its various modules. The support adjustment module 1 solves the problem of fixed and non-adjustable traditional protective devices; the balance and stabilization module 2, through the spring design of the outriggers 9 and the application of anti-slip pads 10, significantly improves the stability of the device in complex terrain; and the ergonomic auxiliary module 3, through the design of the seat 12, backrest assembly 13, and shock absorber 14, greatly enhances the comfort and safety of the workers. These improvements collectively overcome the limitations of existing technologies and meet the comprehensive requirements of modern high-altitude operations for flexibility, safety, and ease of operation.
