Anti-loosening devices and tunneling equipment

Abstract

The invention provides an anti-loosening device and driving equipment. Among them, the anti-loosening device includes: at least two glands, any one of the at least two glands is provided with a mounting groove, and the mounting groove is used to locate the fastener that matches it; the bracket, at least two A gland is set on the bracket. At least two glands of the present invention are connected as a whole through brackets, at least two glands interact and cannot move relative to each other, so that when the anti-loosening device is assembled with the fastener, on the one hand, due to the installation of the gland The groove is adapted to one end of the fastener, so the fastener is limited by the structure of the installation groove and cannot be displaced relative to each other. On the other hand, since the position between at least two glands is relatively fixed, therefore, The fasteners assembled with the anti-loosening device cannot move relative to each other, thereby ensuring a good anti-loosening effect. At the same time, the structure is easy to assemble and disassemble, and can be used repeatedly, which improves the efficiency of assembly and disassembly.

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.
