Description
Technical field
The utility model belongs to safety protection field, is specifically related to a kind of movable pulley falling proof device.
Background technology
Pulley is a kind of important lifting device, simple in structure and easy to use, at present, widely used in lifting industry construction is that steel rope adds movable pulley and carries out lifting work, in lifting process, running into steel rope breaks suddenly or blocks fag end and deviate from, suspension hook and weight meeting free fall, cause the person or property safety accident.
Summary of the invention
The purpose of this utility model is to provide a kind of movable pulley falling proof device, its simple in structure, convenient and practical, safety.
Based on above-mentioned purpose, the utility model is taked following technical scheme:
A kind of movable pulley falling proof device, comprise the movable pulley being installed on bracing frame, and be sheathed on the steel rope on movable pulley, bracing frame bilateral symmetry is provided with anti-falling mechanism, described anti-falling mechanism comprises sleeve, slipper is in the inner set and is sheathed on and carry support outside sleeve, steel wire penetrating sleeve inner, slipper top with carry support upper articulation.
Preferably, sleeve with carry support and be articulated with the hinge hole being arranged on bracing frame by bearing pin, it is above-mentioned that both are positioned at inside steel rope with the articulated position of bracing frame.
Further preferred, described hinge hole is horizontal slotted hole, and bearing pin both sides are provided with pad, and pad is bolted on bracing frame, so that according to the fixing fall arrest holding position of pulley size and position.
Further preferred, sleeve top wire rope inner side is provided with small sheave.
Further preferred, described slipper bottom is provided with the spring being connected with sleeve bottom, and movable pulley and steel rope normal condition lower spring are in extended state, and spring plays the effect of auxiliary braking.
Further preferred, described slipper top with carry the center-of-gravity position of support upper articulation position in slipper.
The beneficial effects of the utility model: the utility model is simple and reasonable for structure, safety, fabrication and installation convenient, practical, when steel rope disconnects, carry support moment and swing to a side, slipper falls simultaneously, now play the effect of auxiliary braking in the spring of extended state, give slipper a pulling force, impel slipper to lock firm steel rope, anti-locking pulley falls, and can be widely used in the occasion of the lifting heavies such as lifting industry, parking systems.
