For realizing above function, device of the present invention is comprised of director, spring, guide cylinder, push rod, lower pilot bar, pins, bar and steel rope.Before lifting, when transferring, suspender rely on suspender deadweight on push rod, to push away, push rod band increment upwards ejects bar to breach along lower pilot bar groove at side surface, bar can be along 45 ° of lower pilot bar upper end helix line breach direction rotations, thereby deviating from lower pilot bar groove at side surface no longer falls, self-position rises and pulls steel rope that pins is moved to the left, thereby realizes locking.After lifting, suspender is transferred to certain distance, utilize suspender deadweight again will on push rod, to push away, after push rod band increment contacts with bar, bar can be along 45 ° of lower pilot bar upper end helix line breach direction rotations.When suspender rises, bar will fall along lower pilot bar groove at side surface, and position declines, and steel rope loosens, and spring pulls pins to move to the right, thereby realizes release.
A kind of mechanical caging of the present invention and tripper, it is mainly by director, the first spring, guide cylinder, lower pilot bar, push rod, sleeve pipe, pins, bearing pin, the second spring, the first sleeve, the second sleeve and bar form, described bar is arranged in the knock hole of director, lower pilot bar is fixed on guide cylinder, described push rod is contained in lower pilot bar, push rod one end is polished rod, the other end is provided with tooth punching, wherein polished rod one end down, in tooth punching one end when work, is along lower pilot bar up-and-down movement, catch bar moves up and down and guide rod rotates, it is characterized in that: described device also comprises steel rope, steel rope one end and director are fixed, the other end is connected with pins, pins can automatically realize the locking of lifting object and lift by crane, can automatic unlocking after having lifted by crane.
Described lower pilot bar side opening is provided with four deep trouths, is evenly distributed on lower pilot bar surrounding, and lower pilot bar top is provided with eight profile of tooth flutings altogether, and wherein four are connected with deep trouth.
Before lifting, when transferring, suspender rely on suspender deadweight on push rod, to push away, when push rod band increment upwards ejects to breach by bar along lower pilot bar groove at side surface, bar can be along 45 ° of lower pilot bar upper end helix line breach direction rotations, thereby deviating from lower pilot bar groove at side surface no longer falls, on position, rise, pull steel rope that pins is moved to the left, thereby realize locking.
After lifting, suspender is transferred to certain distance, utilize suspender deadweight on push rod, to push away, after push rod band increment contacts with bar, bar can be along 45 ° of lower pilot bar upper end helix line breach direction rotations, when suspender rises, bar will fall along lower pilot bar groove at side surface, position declines, and pulls steel rope that pins is moved to the right, thereby realizes release.
Beneficial effect of the present invention:
Structure is relatively simple, is convenient to assembling; Fault is few, and reliability is high; Can realize fast locking and unlocking function, effectively reduce cylinder and play loading lag.
