Abstract
The utility model relates to an anti-falling device for a carrying platform of a stacker crane, which is composed of a braking mechanism arranged between two hanging columns on the same side of the carrying platform, a braking starting mechanism and a vertical braking rail fixed on the inner lateral surface of a crane frame column, wherein the braking mechanism is provided with a pair of braking wheel shafts arranged on a braking wheel shaft seat; a pair of eccentric braking wheels arranged on one end of each braking wheel shaft are positioned on both sides of the vertical braking rail, and the other end of each braking wheel shaft is connected with a linking plate. The braking starting mechanism is provided with a screw rod of which the upper end is connected to a driving chain of the carrying platform; the screw rod downward passes through a crossbeam hole of a hanger rod, a spring and a reverse T column hollow spring seat sheathed in the hole, and is connected with a connecting plate connected with a push rod below. The utility model has the advantages of simpler structure, low cost and high safety.
Description
Technical field
The utility model belongs to the safety device of hoisting crane, particularly relates to stakcer crane and be used for a kind of device of keeping the load suspender member not drop under its chain or wire cable rupture situation.
Background technology
Aisle stacking crane is a kind of high speed weight-lifting equipment, be mainly used in automatic stereowarehouse input, output goods, be characterized in that lifting altitude height, hoisting capacity are big, the loading platform rising or falling speed is fast, therefore prevent that loading platform from falling in the work, guarantee that safety in operation is very important.At present, the anti-dropping safety device of relevant hoisting crane has multiple structures such as electromagnetic type, electromechanical, but most complex structure, the cost height.
Summary of the invention
The purpose of this utility model provides a kind of safe and reliablely, and structure is simpler, and manufacturing cost is lower, is particularly useful for the loading platform anti-fall device of stakcer crane.
Technical solution of the present utility model is: it is formed with the stop mechanism between avris two davits, brake actuating mechanism and the vertical braking rail that is fixed in hoisting crane framework pillar medial surface by being installed on loading platform, its stop mechanism have below the davit crossbeam, be fixed in the brake wheel axle bed between two davits, a pair of brake axle on even keel passes the brake wheel axle bed, the one end is respectively equipped with eccentric brake wheel, two eccentric brake wheels just in time are positioned at the both sides of vertical braking rail, and the other end of brake axle respectively is connected with an interlock plate; Brake actuating mechanism has the screw rod that the upper end is connected with the loading platform messenger chain, be connected with a connecting panel behind the spring that this screw rod lower ends downward is passed socket in suspension rod crossbeam hole and the hole and the cylindricality of the falling T hollow projectile cartridge spring abutment, the hole upper oral part of davit crossbeam is provided with spring limiting board, above-mentioned screw rod connecting panel is connected with the horizontal push of its below again simultaneously, and the horizontal push two ends are connected with two interlock plates of below stop mechanism by extension spring.
Stakcer crane is in service in work, in case the messenger chain fracture takes place, the screw rod of brake actuating mechanism promptly loses pulling force, originally hung the spring that tension and compression are contracted by screw rod and the cylindricality of falling T hollow projectile cartridge spring abutment, this moment, release spring power made the screw rod that connects together, spring perch, connecting panel and push rod move downward fast, and then two interlock plates of promotion stop mechanism, the left avertence heart brake wheel of stop mechanism is rotated counterclockwise, right avertence heart brake wheel clockwise rotates, be clamped on the vertical braking rail of hoist frame column medial surface, and because the action of gravity of loading platform, eccentric brake wheel presss from both sides tighter and tighter to braking rail about making, thereby prevents that reliably loading platform from falling.
The utility model structure is simpler, and cost is low, and is safe and reliable.
