Mine round-link chain split ring quick release mechanism

Abstract

The invention discloses a mine round-link chain split ring quick release mechanism which is characterized in that a split ring is arranged on a round-link chain set; the split ring is locked by a quick release pin which is fixed by a pin and a flat pin. When an operator wants to lock the split ring, the operator can first install the pin on the quick release pin and insert the quick release pin to a hole in the split ring, and then installs the flat pin on the quick release pin, and in such a way, the groove of the flat pin is stuck on the pin and the split ring can be locked. When the operator wants to dismantle the split ring, the operator can knock the protruded part of the flat pin to enable the flat pin to withdraw, then the quick release pin can be taken down and the split ring can be dismantled. The mine round-link chain split ring quick release mechanism has the beneficial effects that the mine round-link chain split ring quick release mechanism solves the problem that a connecting bolt of the round-link chain can not be dismantled due to that the screw threads of the connecting bolt rust, and the mine round-link chain split ring quick release mechanism is simple and quick to install and dismantle.

Description

Technical field [0001] The invention relates to a quick release mechanism of a circular chain split ring, in particular to a quick release mechanism of a circular chain split ring for mining. Background technique [0002] At present, the mine hoists in the prior art usually need to install a large derrick or a well tower at the wellhead, and complete the straight up and down lifting and transportation work through motors, wire ropes, and skips. In addition, the cross-sectional area of ​​the wellbore is large, so the construction volume is large, and the space occupied is also large. The structure is relatively complicated, the operation and maintenance are more troublesome, and the cost is high. The above problems can be solved by installing a chain bucket hoist driven by a circular chain. The circular chain is generally connected by bolts to lock the split ring. In the mine environment, the bolts are easy to be disassembled due to thread corrosion. Contents of the inventi...
