Description

Technical Field

[0001] The utility model relates to the technical field of slips installation, in particular to a slips fastener. Background Art

[0002] At present, during the construction process of the drill used in the mine, when the drill rubber cylinder is severely worn, oil leakage is likely to occur. At this time, it is necessary to repair it, and the machine often needs to be stopped to replace the rubber cylinder during the repair process. When replacing the traditional drill rubber cylinder, it is necessary to first disassemble the chuck, take out the slips assembly and the rubber cylinder in sequence, then install the new rubber cylinder into the chuck, and finally install the slips assembly into the new rubber cylinder. However, when the traditional slips assembly is installed into the new rubber cylinder, since there are many springs on the slips assembly, when installing the slips assembly into the new rubber cylinder, it is necessary to manually fasten the slips inward. Due to the large spring force of the springs on the slips assembly, manual operation is very laborious. The above operation steps take about 2 hours, affecting the drilling efficiency.
