Description

Technical Field

[0001] This utility model relates to the field of geological exploration equipment technology, specifically a fall protection safety device for high-altitude operations in geological exploration. Background Technology

[0002] In the field of geological exploration, high-altitude operations are a common form of work, especially when exploring mineral resources in mountainous and hilly areas. Workers often need to use high-altitude lifting equipment (such as elevators, suspended baskets, etc.) to carry out sampling, observation and other work. These high-altitude work equipment usually rely on ropes for support and suspension to ensure that workers can work safely at different heights.

[0003] However, in actual operation, the hoisting rope is at risk of breaking due to long-term exposure to gravity and external environmental factors (such as wear, corrosion, aging, etc.). Once the hoisting rope breaks, the high-altitude work equipment will lose support, which may cause workers to fall and cause serious safety accidents.

[0004] To ensure the safety of workers, some fall protection devices for high-altitude operations are already available on the market. However, these devices often have some shortcomings. For example, some devices cannot respond in time when the suspension rope breaks, resulting in poor fall protection. Some devices can respond to suspension rope breakage, but there are unstable factors when they are used in conjunction with the safety rope, which may not be able to effectively prevent falls. Some devices have complex structures and high maintenance and usage costs, which are not conducive to their widespread application in actual operations.

[0005] Therefore, in view of the shortcomings of the existing technology, there is an urgent need to provide a fall protection safety device for high-altitude operations in geological exploration that can respond quickly when the suspension rope breaks, work stably with the safety rope, has a simple structure and is easy to maintain.
