Abstract
The utility model discloses a tower crane mounted with an anti-fall off safe lifting hook. The tower crane mainly comprises a tower crane body, the lifting hook, a pulley, a self-locking nut, a bilateral rack, a fixing pin shaft and an elastic cylindrical pin, wherein the bilateral rack is mounted on the pulley; the fixing pin shaft is connected with the bilateral rack and the pulley; the self-locking nut as well as the elastic cylindrical pin is connected with the bilateral rack and the lifting hook. The tower crane has the benefits that the structure is simple; the realization is easy; the falling possibility of the lifting hook is greatly reduced during practical operation.
Description
Technical field
The utility model relates to a kind of construction trade tower crane device, is specially a kind of tower crane that is mounted with drop proof safety hook.
Background technology
At present, known crane hook, all that the hook head of suspension hook is hung on steel cable pulley, its crotch is directly hooked in transportation brick, on the hopper lifting rope of stone material, when in lifting, the steel rope the hanging larger swing that happens occasionally, especially that swing to and fro and bob, the masonry being contained in hopper that will happen occasionally dishes out to fall from high-altitude, especially there is lift hook unhooking accident, light spolied materials, heavy the hopper generation human casualty accident that falls down, this class accident, concerning tower crane promotes, of common occurrence, current harmonious society, people-oriented, so propose to solve this safety related technical problems, extremely urgent.
Utility model content
The purpose of this utility model is the deficiency existing according to above-mentioned prior art, and a kind of tower crane that is mounted with drop proof safety hook is provided.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of tower crane that is mounted with drop proof safety hook, mainly by tower crane body, suspension hook, pulley, self lock nut, double sided rack, fixed pin shaft and elastic cylindrical pin, formed, on described pulley, be mounted with double sided rack, fixed pin shaft connects double sided rack and pulley, self lock nut connects double sided rack and suspension hook, and elastic cylindrical pin connects double sided rack and suspension hook.
Described fixed pin shaft is provided with screw thread and coordinates with double sided rack.
Described elastic cylindrical pin has four, two tops that are positioned at self lock nut wherein, and two other is positioned at the below of self lock nut.
Described elastic cylindrical pin connects up and down between two.
The beneficial effects of the utility model are: simple in structure, be easy to realize, by tooth bar and screw thread self-locking with cylindrical pin, the locking function of self lock nut also has the fixation of elastic cylindrical pin, for the safety of suspension hook, do three insurances, in practical operation, greatly reduced the possibility of suspension hook landing.
