Abstract
The utility model relates to an anti-falling device for lifter platform, comprising a braking device on the lateral plate of the platform, a starter and a vertical brake rail fixed on the inner side an upright column of a lifter; the upper end of a suspender of a starter device is connected with a drive chain of the platform and the lower end is connected with the bottom of a slide block of the braking device through an elastic connecting plate and a brake chain, a spring is arranged in the low part of vertical rod of the slide block, and a pair of horizontal axes are positioned through the brake wheel plate, and one end is connected with the sliding block and a brake wheel is arranged on the other end. The two brake wheels are arranged on two sides of the brake rail as well as between a pair of bevel wedge brake guide bars arranged on the brake wheel seat. With the advantages of simple structure and easy installation and operation, the utility model is especially applicable to the platform of the lifter against falling of a platform due to sudden breakage of the transmission chain.
Description
Technical field
The utility model belongs to the safety device of gig, particularly relates to gig and be used for a kind of device of keeping the load suspender member not drop under its driving chain or wire cable rupture situation.
Background technology
Back and forth gig is a kind of heavy load transfer device, is mainly used in the vertical-lift of goods, is characterized in the hoisting depth height, weight is big, the loading platform rising or falling speed is fast, therefore prevents that loading platform from falling in the work, guarantees that safety in operation is very important.At present, relevant anti-dropping safety device has multiple structures such as electromagnetic type, electromechanical, but most complex structure, the cost height.The applicant had once designed a kind of loading platform anti-fall device (number of patent application is 200520014957.8) of stakcer crane.Its stop mechanism is brake component with the camshaft, and anti-fall braking force is the application force between two eccentric brake wheels and the frame braking rail, and whole stop mechanism firmly is welded on the loading platform.Its structure is comparatively simple, flexible movements, loading platform falling accident in the time of preventing the fracture of hoisting crane messenger chain accident reliably.But this device is had relatively high expectations to the straightness accuracy and the installation site of braking rail.
Summary of the invention
The purpose of this utility model provides a kind of reliable operation, and is simple in structure, installation, easy to use, and manufacturing cost is lower, is particularly useful for the loading platform anti-fall device of reciprocal gig.
Technical solution of the present utility model is: it comprises the stop mechanism that is installed on the loading platform side plate, brake actuating mechanism and the vertical braking rail that is fixed in gig column medial surface, its stop mechanism has the brake wheel seat board, on the backboard face of brake wheel seat board, be provided with the inclined wedge-shaped braking gib block in the up-small and down-big space of a pair of mutual formation, offer hole on the seat board between the two-system action-oriented bar, a pair of brake axle on even keel passes hole, and brake wheel is installed at the end between two-system action-oriented bar, the other end connects slide block, slide block then is sleeved on a pair of vertical guide stem versatilely, the upper and lower side of vertical guide stem be fixed on the positive plate face of brake wheel seat board on, on the lower protruding block, on the vertical guide stem section between slide block and the lower protruding block, spring is installed also, above-mentioned brake wheel seat board is installed on loading platform side plate medial surface middle and lower part, the braking gib block at the seat board back side and brake wheel then pass the hole on the side plate, and make a pair of brake wheel lay respectively at the both sides of vertical braking rail; Brake actuating mechanism has the suspension rod that the upper end is connected with the loading platform messenger chain, this suspension rod lower ends downward is passed the protruding beam in side plate medial surface top, be connected with connecting panel, be set with spring on the boom sections between connecting panel and the protruding beam, be fixed with the chain pipe link on the connecting panel simultaneously, the braking chain is connected in by the changed course sprocket wheel between the chain pipe link at slider bottom center of the chain pipe link of connecting panel and stop mechanism.
During the gig normal operation, loading platform is hung on the messenger chain, spring between suspension rod pull-up connecting panel compression connection plate and the protruding beam is held the braking chain simultaneously and is made slide block move down the spring that compresses between slide block and the lower protruding block, and the brake wheel that link to each other with slide block this moment is in no restrained condition.In case the messenger chain fracture takes place, the suspension rod of brake actuating mechanism promptly loses pulling force, originally discharged elastic force by the spring of suspension rod and connecting panel compression, promoting connecting panel moves downward and the braking chain that relaxed, and then make the spring that is braked chain and the drop-down compression of slide block originally discharge elastic force, slide block is driven move on the brake wheel braking rail to brake the stenosis between the gib block with inclined wedge-shaped and be stuck, this moment is under the action of gravity of loading platform, brake wheel can be blocked tighter and tighter, thereby prevents that reliably loading platform from falling.
The utility model structure is simpler, and is easy to install, loading platform falling accident in the time of preventing the fracture of gig messenger chain accident reliably.
