Description

Technical Field

[0001] The utility model relates to the technical field of anti-loosening bolts, in particular to an anti-loosening bolt structure for geological mining machinery. Background Art

[0002] Mining machinery is machinery directly used for mineral mining and enrichment, including mining machinery and mineral processing machinery. The working principle and structure of prospecting machinery are mostly the same or similar to those of mining machinery used for mining similar minerals. In a broad sense, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are also used in mining operations. The fixation of mining machinery and various parts requires the use of bolt structures. The existing anti-loosening bolt structures of geological mining machinery mostly use a combination of bolts, washers and nuts to fix the equipment. However, mining machinery vibrates greatly during operation, which makes it easier for the bolts to loosen, thereby affecting the use and operation of the equipment. The China Patent Network discloses a geological and mining machinery anti-loosening bolt structure labeled "CN217234068U", which is designed with several fixing parts. The lower end of the middle fixing part and the inner end face of the lower fixing part are respectively fixed and provided with a middle threaded rod and a threaded groove which are rotatably connected. The lower end of the upper fixing part and the middle part of the middle threaded rod are respectively fixed and provided with an upper threaded rod and a middle threaded hole which are rotatably connected. An upper clamping plate is fixed to the lower end of the spring, and a lower clamping plate is slidably installed on the outer side of the lower threaded rod to push the lower clamping plate and the upper clamping plate to move toward the middle, so that the threaded fit between the upper fixing part and the lower fixing part is tighter. However, the structure is complicated during use and the manufacturing is too troublesome. Therefore, an anti-loosening bolt structure for geological and mining machinery is provided.
