Problems solved by technology

In the related technology, when the cutting head and the main shaft are assembled with bolts, the thread fastening glue is applied to prevent the bolts from loosening. Therefore, the problem of bolt loosening frequently occurs during the working process of the cutting head, and the anti-loosening effect is unreliable. And after the bolts are loose, it is easy to cause the bolts to break or even the cutting head to fall, which cannot guarantee the safety and reliability of the equipment.

Abstract

The invention provides an anti-loose device and excavating equipment. The anti-loose device comprises at least two press covers and a support, wherein an installation groove is formed in one arbitrarypress cover in the two press covers, the installation groove is used for locating a fastening part matched with the installation groove, and the two press covers are arranged on the support. According to the anti-loose device, the two press covers are connected into one through the support, and the two press covers interact so that the two press covers cannot move relatively, then when the anti-loose device and the fastening part are matched, on one hand, due to the fact that the installation groove of the corresponding press cover is matched with one end of the fastening part, the fasteningpart is limited by the structure of the installation groove, and cannot take place relative displacement, and on the other hand, due to the fact that positions of the two pressure covers are relatively fixed, the anti-loose device and the fastening part which are fit together cannot move relatively, so that an excellent anti-loose effect is guaranteed. Meanwhile, the structural device is easy to disassemble and assemble, and can be used over and over again, so that the efficiency of assembly and disassembly is improved.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to an anti-loosening device and excavation equipment. Background technique [0002] As the main working mechanism of the engineering roadheader, the cutting head's working performance and the safety of the bolt connection determine the construction efficiency of the entire equipment and affect the overall construction progress of the project. In the related technology, when the cutting head and the main shaft are assembled with bolts, the thread fastening glue is applied to prevent the bolts from loosening. Therefore, the problem of bolt loosening frequently occurs during the working process of the cutting head, and the anti-loosening effect is unreliable. And after the bolt is loosened, it is easy to cause the bolt to break or even the cutting head to fall, so that the safety and reliability of the equipment cannot be guaranteed.
