Further improve as the utility model, described upper anti-break pin is two, is symmetricly set in the both sides of the longitudinal plane of symmetry formed by sheave shaft and crossbeam respectively.
Further improve as the utility model, described upper anti-break pin is positioned at the top of described pulley.
Further improve as the utility model, described lower anti-break pin is two, is symmetricly set in the both sides of the longitudinal plane of symmetry formed by sheave shaft and crossbeam respectively.
Further improve as the utility model, described lower anti-break pin is positioned at the below of described pulley.
Further improve as the utility model, described crossbeam is provided with through hole, the bottom of described suspension hook 1 is passed described through hole and is connected on described crossbeam by suspension hook pin mother.
Further improve as the utility model, described closing appliance comprises the insurance clamp being hinged in described suspension hook root, is provided with torsion spring between described insurance clamp and suspension hook.
Further improve as the utility model, bottom described suspension hook and between described crossbeam, be provided with pressure bearing.
Further improve as the utility model, described first backplate and the second side guard plate are heavier-duty backplate.
Compared with prior art, the beneficial effect acquired by the utility model is as follows:
In the utility model, upper anti-break pin and lower anti-break pin can prevent from steel rope from spending because of angle of pull departing from race greatly, avoid the generation of steel rope casualty accident, greatly enhance the steadiness of coaster entirety simultaneously.
Bottom suspension hook of the present utility model, crossbeam binding site is provided with pressure bearing, this just adds the harmony of the entirety of coaster to a great extent, prevents the generation of drawing inclined phenomenon.
The heavier-duty backplate that the utility model is used, makes the tensile property of coaster strengthen, improves the safety factor of coaster.
The utility model possesses the feature that simple, easy to use, the overall tensile strength of structure is high, safety performance is stronger.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is right elevations of the present utility model.
In the accompanying drawings:
