Although current hovering locking mechanism can be realized locking, its complex structure, inconvenient operation, and be arranged on actuating device or assembly pulley, strengthened to a certain extent the risk of these component failures. more
For example " 201120079130.0; a kind of catch gear of lifting machinery "; the utility model discloses a kind of catch gear of lifting machinery, the structure of its catch gear is: vertical supporting plate hanger bar and its bottom and lifting supporting plate are set on lifting supporting plate and are fastenedly connected; Catch gear is established vertical locking push rod, pushing rod sleeve and hanger bar cover, and supporting plate hanger bar and locking push rod are bearing fit with hanger bar cover and pushing rod sleeve respectively; Supporting plate hanger bar and the relative side of locking push rod, establish respectively the inclined-plane low-angle, direction of tilt is identical.This apparatus structure is complicated, and has potential safety hazard.
Summary of the invention
The utility model aims to provide a kind of locker, and the reliable locking of the cage that can guarantee gig when hovering loading, unloading goods, avoids derailing accident to occur, and guarantees safety.
For achieving the above object, the utility model is by the following technical solutions: a kind of locker, comprise 1～4 group of clamping unit and locking lever, clamping unit is arranged on integral elevating cage, match with the vertical main framework of cage, locking lever is arranged on cage fluctuating orbit, locking when both cooperations realize cage hovering.
Clamping unit comprises block shell 1, moving slider 2, pull bar 3, nut 4 and pulley 5, described block shell 1 is for there being the convex structure of gear mouth 6 on hollow and camber line, its bottom surface is fixedly connected with the vertical main framework of cage, the lower end of block shell 1 inside is provided with the moving slider 2 that cross section is equilateral triangle, the base of moving slider 2 is parallel with the bottom surface of block shell 1, one end of pull bar 3 is fixed by nut 4 and the top of block shell 1, the other end through behind the top of block shell 1 with one side sliding block joint of moving slider 2, moving slider 2 can along be positioned at the pulley 5 on base and under the directional tagging of pull bar 3 along on the bottom surface of block shell 1, lower slider.
Locking lever comprises gusset piece 7, push rod 8, elastomeric element 9 and hanger bar cover 10, described hanger bar cover 10 is fixed by gusset piece 7 and cage fluctuating orbit, described push rod 8 and elastomeric element 9 are installed in hanger bar cover 10 and overlap 10 bearing fits with hanger bar, hanger bar is overlapped to 10 rear bolt tightenings and make elastomeric element 9 compressions, promote the moving slider 2 of push rod 8 compression clamping units to complete locking.
principle of work: the utility model is in the normal uphill process of cage, because the limit of moving slider 2 is hypotenuse, the rear continuation of compressible elastomeric parts 9 is risen, when cage arrives predetermined altitude, while needing handling goods, motor stops, now, push rod 8 is pulled to the gear mouth 6 places locking of block shell 1 under the effect of elastomeric element 9, blocks cage tenesmus.When cargo handing completes need to rise time, push rod 8 is abdicated under the effect of moving slider 2 hypotenuses, and cage just can rise; During decline, need cage first upwards to carry a segment distance, so that push rod 8 allows the bottom of moving slider 2, moving slider 2 rises along pulley under the effect of push rod 8, makes its high point be positioned at gear mouth 6 places of block shell 1, and cage just can normally decline.
Described elastomeric element 9 is springs.
For improving stability and the reliability of cage hovering, above-mentioned locker is set to the structure being comprised of 2 groups or 4 groups of clamping units and locking lever, and is arranged on the place, diagonal angle of cage.
The utility model locker drive transmission device for gig in cage operational process does not does not wear and tear, can guarantee that the cage of gig is in hovering maintenance motor, reliable locking during loading, unloading goods, shut-down operation safety, avoid derailing accident to occur, guarantee safety.And simple in structure, processing technology is simple, operation and control are convenient.
