Description

Technical Field

[0001] The present utility model relates to the technical field of scraper conveyors, and particularly to a protection device for a scraper conveyor. Background Art

[0002] A scraper conveyor refers to a transportation machine used in coal mining working faces. When the scraper conveyor is in operation, in order to ensure its normal operation and prevent flying stones and other foreign objects from impacting and damaging the internal transmission machinery of the scraper conveyor, a protective structure such as a protective net is generally provided outside the body of the scraper conveyor to intercept flying stones and other foreign objects and prevent them from entering the inside of the scraper conveyor body through the open end at the top of the scraper conveyor body. However, the protective structure currently set outside the scraper conveyor body only has a single interception function. When a foreign object impacts and contacts the scraper conveyor or foreign objects such as coal transported are splashed out due to a fault inside the scraper conveyor body, it can only intercept, but cannot remind the staff at the same time of the interception, so that the staff cannot timely discover the fault of the scraper conveyor and know the reason why there is a foreign object impact at present. Summary of the Invention

[0003] The present utility model relates to a protection device for a scraper conveyor. When a foreign object impacts and contacts the woven net used for covering and shielding from the inside or outside of the scraper conveyor body, the shielding frame plate will move along the shielding frame block following the impact direction, thereby synchronously enabling a group of warning switches to be in a pressed and activated state. Through the command feedback of the warning switches, a message will be wirelessly sent to the staff immediately, so that when a foreign object impacts and contacts, the staff can know immediately, facilitating their timely visit for observation and maintenance to avoid the fault damage of the scraper conveyor caused by the foreign object impact.

[0032] Working principle of this embodiment:

[0033] The front mounting seat 1 is fixedly installed on the scraper conveyor body through fasteners that pass through the mounting hole positions a101 and are fixedly connected to the scraper conveyor body. Similarly, the rear mounting seat 2 is fixedly installed on the scraper conveyor body through fasteners that pass through the mounting hole positions b201 and are fixedly connected to the scraper conveyor body.

At this time, a section of the opening end at the top of the scraper conveyor body is covered and shielded by the shielding frame block 3, the shielding frame plate 4, and the woven mesh 401. For the complete coverage and shielding of the opening end at the top of the scraper conveyor body, the corresponding number of this utility can be selected according to the length of the scraper conveyor body to cover and shield the entire area of the opening end at the top of the scraper conveyor body;

[0034] When the bottom end surface of the shielding frame block 3 is in contact with the top of the long ends of the front mounting seat 1 and the rear mounting seat 2, at this time, the two stud bolts 103 are respectively inserted into the two insertion hole positions 302, and are temporarily fixed by the nuts 104 in the threaded locking state along the stud bolts 103;
