Description

Technical Field

[0001] This utility model relates to a retractable protective device for a transfer machine, belonging to the field of transfer machine safety protection technology. Background Technology

[0002] In underground coal mining operations, the coordinated operation of the scraper conveyor and the transfer conveyor at the working face is crucial. They typically employ an end-discharge unloading method, where the head of the scraper conveyor overlaps one side of the transfer conveyor's unloading chute. In actual production, as coal mining progresses, the scraper conveyor moves forward, resulting in relative movement between it and the transfer conveyor.

[0003] In the unloading section of the transfer conveyor, the side space near the conveyor head is not enclosed. In other words, the tail of the transfer conveyor and the unloading section are designed in an open manner. This open area directly faces the underground workers, and it is a crucial path for their daily operations, equipment maintenance, and passage. Due to the lack of effective protective measures in this area, there is a significant safety hazard when underground workers pass through this section while operating, inspecting, or maintaining equipment. Past cases have frequently shown that materials accidentally fall from the unloading section, or personnel inadvertently approach moving parts, leading to personal injury accidents, causing varying degrees of injury, and even death, resulting in heavy losses for the company's production and the families of its employees.

[0004] To effectively address the aforementioned safety issues, protective devices for transfer conveyors are commonly used in actual operations. These devices encompass a range of equipment and systems designed to protect the safety of transfer conveyor operators and equipment. Their core function is to prevent personnel from accidentally entering hazardous areas and to stop materials from falling and injuring people, thus ensuring the safety of personnel and equipment in all aspects. However, existing protective devices still suffer from numerous problems in design and practical application, such as inadequate protective effects and inconvenient installation and maintenance, making it difficult to fully meet the safety protection needs of the complex and ever-changing underground working environment. Therefore, developing a more efficient, reliable, and adaptable protective device for transfer conveyors suitable for complex underground working conditions is of urgent practical significance.
