Background
The stacker is a special crane which takes a fork or a string rod as a fetching device and grabs, carries and stacks the goods in a warehouse, a workshop and the like or takes and places unit goods from a high-rise goods shelf. The stacker is a main operation machine of an automatic stereoscopic warehouse, the lifting capacity of the stacker is 1t, the lifting height is mostly between 8 and 20m and even higher, and high lifting weight and lifting height also mean high risk factor. In the prior art, the starting procedure of the protection device of the stacker is that after a steel wire rope is broken, an object stage loses weight and rapidly falls, and when the falling speed of the object stage reaches a certain speed, a limiter starts the protection device, and the object stage stops falling. Although the object stage can be prevented from falling down in this way, the object stage has a potential safety hazard before falling to the limiting speed in an uncontrolled way, and sometimes the limiting starting device reacts insufficiently and is not started because the object stage falls to the ground and the protection device is not started.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can start instant reaction safety device of stacker safety tongs to the not enough of prior art.
In order to achieve the above purpose, the utility model discloses a technical scheme is: the improvement of the safety device for the instant reaction of the stacker comprises a movable pulley block and a connecting rod mechanism, wherein the movable pulley block comprises a movable pulley, the movable pulley is arranged on a pulley mounting frame, the pulley mounting frame is fixedly arranged on a pulley fixing plate, the pulley fixing plate is arranged on a bottom plate of a cargo carrying platform through two lead screws, and the end of the lead screw positioned at the upper part of the pulley fixing plate is provided with a limit nut; the connecting rod mechanism comprises a short rod, one end of the short rod is connected with the cargo carrying table wall through a fixed pin shaft, the short rod can rotate around the fixed pin shaft, the other end of the short rod is installed on a screw rod below the pulley fixing plate, the middle position of the short rod is hinged with an adjustable connecting rod through a pin shaft, the other end of the adjustable connecting rod is hinged with a safety tongs starting swing arm, and the safety tongs starting arm is used for starting safety tongs.
Preferably, a spring is arranged between the limiting nut and the pulley fixing plate.
The utility model discloses utilize the heavy power of movable pulley dead weight to make link mechanism start safety tongs, can realize that stacker wire rope fracture is in the twinkling of an eye, just start safety tongs when the objective table begins to descend and make the objective table stop the tenesmus, reduce the potential safety hazard.
