Abstract
The invention discloses a crane hook assembly which comprises a plurality of pulleys, two clamping plates and a hook, wherein the two clamping plates are connected and fixed by an upper cross beam and a lower cross beam, the upper end of the hook is fixed on the lower cross beam, the upper end of the hook is screwed and fixed on the lower cross beam by a combined nut, the pulleys are arranged between the two clamping plates and are rotatably fixed by a pulley shaft, a guide rope block is arranged in the chute of each pulley, the upper side and the lower side of the pulley are provided with round bar nuts arranged between the two clamping plates so as to limit the displacement of the pulleys. According to the crane hook assembly, a pulley block is arranged between the two clamping plates, and limit screws are arranged at the upper and lower positions of the pulley, so as to avoid the safety problem caused by pulley separation due to failure of the pulley shaft; an anti-tripping gear is arranged on the hook to ensure that a weight cannot be unhooked; secondary anti-tripping rope penetration holes are formed in the two clamping plates, so as to play a role of buffering when the hook separates, thus reducing the damage of accidents. The crane hook assembly is compact in structure and convenient and practical.
Description
Technical field
The present invention relates to lifting technique field, particularly to a kind of crane hook assembly being applied to crane.
Background technology
Crampon, is the parts of a kind of crane, and crampon designs the risk brought lack of standardization, and as malfunctioning in overload protection, balancing axle insufficient strength, nothing prevent the selection of tripping gear, suspender rigging unreasonable；Next to that manufacturing defect and defective mounting etc., such as selection is improper, crudy is bad, makes to use with the equipment investment of hidden danger.And substantial amounts of problem is present in use link, for instance, changing faulty part not in time, lack necessary security protection, maintain bad being operating only haltingly, so that causing uncontrolled movements, part or structural deterioration, irregularly carrying out Safety Inspection etc..In a word, design, manufacture, install, use and the defect of any link such as inspection is all likely to bring suspension hook to hang the serious consequence that thing falls.The essential safety of crane is to ensure that the primary condition of hoisting operation safety.
Summary of the invention
In order to overcome drawbacks described above, the invention provides a kind of stabilized structure, the crane hook assembly of essential safety.
The present invention is to solve that its technical problem be the technical scheme is that a kind of crane hook assembly, including some pulleys, two clamping plate and coupler body, said two clamping plate connect fixing by entablature and sill, the upper end of described coupler body is fixed on sill, coupler body upper end is tightened to sill by combination nut, described pulley is arranged between two clamping plate, and rotated fixing by pulley spindle, conductor rope block is installed in the chute of each pulley, the both sides up and down of described pulley are provided with the round bar nut being arranged between two clamping plate for limiting the displacement of pulley.
As a further improvement on the present invention, the upper end of described coupler body is rotated by a bearing and is arranged on sill, and the lower end of described coupler body is provided with Anti-hook releasing device.
As a further improvement on the present invention, the top of said two clamping plate is provided with the perforation for wearing secondary mousing hawser.
The invention has the beneficial effects as follows: the crane hook assembly of the present invention arranges assembly pulley between two clamping plate, and Limit screw is set at the upper-lower position place of pulley, prevent owing to the problem of pulley spindle causes that pulley departs from the safety problem caused, suspension hook is installed Anti-hook releasing device, it is ensured that weight will not break off relations, two clamping plate arrange the perforation of secondary mousing hawser, for guaranteeing to play cushioning effect when suspension hook departs from, the hazardness of reduction accident, present configuration is compact, convenient practicality.
