Abstract

The utility model relates an insulation hoisting hook device which is mainly used in the plants adopting the electrolysis process to smelt nonferrous metals such as aluminum and magnesium; the insulation hook device comprises a hoisting hook (1), a pulley housing (2), a cross beam (3), a hanging plate (4), a hook nut (5), a pulley shaft (6) and a pulley (7); wherein the pulley (7) and the pulley housing (2) both adopt insulation materials; the left pulley and the right pulley are respectively arranged on the two ends of the pulley shaft (6) and provided in the pulley housing (2); the left hoisting plate and the right hoisting plate are sleeved on the pulley shaft (6) and provided on the internal side of the pulley housing (2); the cross beam is connected between the left and the right hoisting plates (4) and provided under the pulley shaft (6); the hoisting hook (1) is hoisted in the middle of the cross beam (3); the hook nut (5) is rotatedly provided on the top of the hoisting hook (1). The utility model has the advantages of compact structure, light hoisting device and basically invariable size; furthermore, the utility model doesn't reduce the hoisting height of a crane.

Description

The insulation cargo hook gear
Technical field
The utility model relates to a kind of lifting mechanism of hoisting crane, especially relates to a kind of insulation cargo hook gear of hoisting crane.Belong to the elevator machinery technical field.
Background technology
The supporting weight-lifting equipment of insulation cargo hook gear is mainly used in and adopts electrolysis process (method) to smelt the factory of non-metals equipment such as aluminium, magnesium, effectively to prevent in the course of the work, charging equipment contacts with load hook, causes hoisting crane charged, jeopardizes driver's life and device security.Existing insulation cargo hook gear generally is by the insulation of insulation boatswain chair, though the insulation boatswain chair guarantees to insulate between suspension hook and pulley shell, the pulley.But in order to guarantee mechanical strength and dielectric strength requirement, the boatswain chair thickening that need extend also need be reinforced between two boatswain chairs, and this spline structure is compact inadequately, makes that cargo hook gear is very heavy, external form is big, and is bigger to effective lifting altitude influence of hoisting crane.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of compact conformation, safe and reliable insulation cargo hook gear are provided.
The purpose of this utility model is achieved in that a kind of insulation cargo hook gear, it is characterized in that it comprises suspension hook, pulley shell, crossbeam, boatswain chair, hook nut, sheave shaft and pulley,
Described pulley and pulley shell adopt insulating material, and pulley has two, and left and right each one, be installed on the two ends of sheave shaft respectively, and place in the pulley shell,
Described boatswain chair has two, and left and right each one, be placed on the sheave shaft, and place the inboard of pulley shell,
Described crossbeam is connected between left and right two boatswain chairs, and places the sheave shaft below,
Described suspension hook is lifted in the middle of the crossbeam, and hook nut is spun on the suspension hook top.
Pulley of the present utility model and pulley shell adopt insulating material, cause between steel rope and the suspension hook and insulate, and that is to say between suspension hook and the electric block body and insulate.
Its principle of work is: the weight-lifting equipment steel rope contacts with pulley, pulley shell, pulley and pulley shell contact with boatswain chair and sheave shaft again, pass to steel rope and weight-lifting equipment body because of pulley and pulley shell adopt insulating material to block electric current by suspension hook, thereby reach the non-conductive purpose.
The beneficial effects of the utility model are: owing to adopt pulley and pulley shell insulation, the boatswain chair of the thickening cargo hook gear that need not extend need not reinforced between two boatswain chairs yet, compact conformation like this, make cargo hook gear very light and handy, overall dimensions are constant substantially, can not influence the lifting altitude of hoisting crane.
Description of drawings
Fig. 1 is the utility model insulation cargo hook gear overall structure scheme drawing.
Among the figure: suspension hook 1, pulley shell 2, crossbeam 3, boatswain chair 4, hook nut 5, sheave shaft 6, pulley 7.
The specific embodiment
Referring to Fig. 1, the utility model insulation cargo hook gear mainly is made up of suspension hook 1, pulley shell 2, crossbeam 3, boatswain chair 4, hook nut 5, sheave shaft 6 and pulley 7.
Described pulley and pulley shell adopt insulating material, and pulley 7 has two, and left and right each one, be installed on the two ends of sheave shaft 6 respectively, and place in the pulley shell 2,
Described boatswain chair 4 has two, and left and right each one, be placed on the sheave shaft 6, and place the inboard of pulley shell 2,
Described crossbeam 3 is connected between left and right two boatswain chairs 4, and places sheave shaft 6 belows,
Described suspension hook 1 is lifted in the middle of the crossbeam 3, and hook nut 5 is spun on suspension hook 1 top.
Pulley and pulley shell are selected the TMC nylon material of high rigidity for use, can keep the good mechanical properties under the high temperature.Pulley insulation voltage withstand has good insulating power and fire retardant performance greater than 1500V, and is aesthetic in appearance, easy for installation.
Described above is sister block insulation cargo hook gear, also has single-sheaved block and many pulleys insulation cargo hook gear, and principle is identical with sister block insulation cargo hook gear, does not repeat them here.
