In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the lifting hook structure of the tower crane comprises a lifting mechanism 1 and a hoisting mechanism, wherein the hoisting mechanism is connected to the lower end of the lifting mechanism; the hoisting mechanism comprises a mounting part and a plurality of lifting hooks, and the lifting hooks are uniformly arranged along the lower end of the mounting part.

Preferably, the lifting mechanism comprises a connecting seat, wherein a group of movable pulleys are symmetrically arranged at the upper end of the connecting seat, and a group of vertical beams are symmetrically arranged at the lower end of the connecting seat; the upper end of the lifting mechanism is connected with the tower crane through a movable pulley, and the lower end of the lifting mechanism is connected with the hoisting mechanism through a vertical beam.

Preferably, the mounting part comprises a balance weight, a group of lifting lugs are symmetrically arranged at the upper end of the balance weight, and the lifting lugs are detachably connected with the corresponding vertical beams through pin shafts.

Preferably, the installation part is rectangular frame structure, and the lifting hooks are uniformly arranged on four corners of the rectangular frame.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

this application is through setting up four couples and will four couples are fixed on rectangular frame, just couple even symmetry sets up, when using, is in four couples accurate hanging on the hoisting frame, further promotes standard festival again, in the promotion in-process, because the lifting hook structure even symmetry of this application sets up, can improve the stability of hoist and mount in-process, thereby avoid too rocking the condition that the standard festival drops in hoist and mount in-process appears, further promotes the security of hoist and mount in-process to improve hoist and mount efficiency.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Example 1

As shown in fig. 1, a lifting hook structure of a tower crane comprises a lifting mechanism 1 and a hoisting mechanism 2, wherein the hoisting mechanism 2 is connected to the lower end of the lifting mechanism 1; the hoisting mechanism 2 comprises a mounting portion 21 and a plurality of hooks 22, wherein the hooks 22 are uniformly arranged along the lower end of the mounting portion 21. The application has set up hoist mechanism 1, hoist mechanism 1 is used for promoting the standard festival that hoist mechanism 2 lifted, hoist mechanism 2 is used for hoisting standard festival. When the lifting mechanism is used, the lifting mechanism 1 is connected with the tower crane, the lifting mechanism 2 is connected with the lower end of the lifting mechanism 1, the lifting hook is hung on the lifting frame, the lifting frame is connected with the standard section, and the lifting and descending of the standard section are performed through the movable pulley 12 on the lifting mechanism 1.

Specifically, the lifting mechanism 1 comprises a connecting seat 11, a group of movable pulleys 12 are symmetrically arranged at the upper end of the connecting seat 11, and a group of vertical beams 13 are symmetrically arranged at the lower end of the connecting seat 11; the upper end of the lifting mechanism 1 is connected with the tower crane through a movable pulley 12, and the lower end of the lifting mechanism 1 is connected with the hoisting mechanism 2 through a vertical beam 13. The utility model provides a lifting mechanism, including connecting seat 11, hoisting mechanism 2, standard festival, movable pulley 12, the symmetry is provided with a set of movable pulley 12 on the connecting seat 11, movable pulley 12 with the tower machine is connected, when using, adjusts through movable pulley 12 the height of standard festival, right the standard festival promotes, simultaneously 11 lower extreme symmetries of connecting seat set up a set of vertical beam 13, vertical beam 13 with hoist mechanism 2 connects, hoist mechanism 2 is used for hoisting the hoisting frame and further lifts up the standard festival again, or directly lifts up the standard festival, because the structure setting of hoist mechanism 2 of this application, when promoting the standard festival, stability is higher.
