Document Type and Number:
WIPO Patent Application WO/2013/159381
Kind Code:
A1
Abstract:
Disclosed is a shear pin (100), comprising: a gas cylinder (1), a first interface (11) and a second interface (12) being provided on the gas cylinder; a piston (2), provided in the gas cylinder (1) so as to separate the gas cylinder (1) into a first cavity (13) communicating with the first interface (11) and a second cavity (14) communicating with the second interface (12); an inserted pin (3) fixed onto the piston (2); and a compressed air supply device (4), supplying compressed air to the first cavity (13) or the second cavity (14). The shear pin (100) uses the inserted pin (3) fixed to the piston (2), the piston (2) dividing the cavity of the gas cylinder (1) into two, and compressed air being injected into the gas cylinder (1) in order to push the inserted pin (3) to retract, achieving the function of automatic insertion or retraction of the shear pin, and eliminating the safety risks of manual insertion of a shear pin.
