Abstract
The utility model provides a lifting hook with a three-sided rope blocking rack structure, comprising a pulley and a hanger arranged below the pulley, wherein rope blocking racks are respectively arranged at the left side, the right side and the lower side of the pulley, each rope blocking rack comprises a panel and a rope blocking plate vertically arranged on the panel, wherein the distance between two adjacent rope blocking plates is larger than the diameter of the head of a steel wire rope wound on the pulley. For the lifting hook with the three-sided rope blocking rack structure, the rope blocking racks are respectively arranged at the left side, the right side and the lower side of the pulley, so that the steel wire rope is prevented from jumping out of the pulley, and simultaneously the winding of the steel wire rope without disassembling is also realized, thus greatly reducing the work quantity of workers on site, and effectively improving the labor efficiency.
Description
Technical field
The utility model relates to a kind of lifting hook, particularly, relates to a kind of lifting hook of three ward off rope support structures.
Background technology
Usually, lifting hook is by the steel rope weight of slinging.But because the operating mode of hoisting operation and hoisting heavy is different, steel rope is easy to occur the unhook phenomenon, thereby has influenced work efficiency, and has certain potential safety hazard.
Therefore, having the lifting hook that keeps off rope structure just arises at the historic moment.China utility model granted patent CN201485173U just discloses a kind of single hook rope warding machine mechanism that is used for hoisting crane, it is captiveed joint block back with spring by bearing pin with suspension hook neck place, make block back to be placed on suspension hook groove neck by actv., thereby realize having stoped the outer cunning of steel rope.
In addition, in the prior art, also have a kind of lifting hook that has retaining rope bar structure, its structure as shown in Figure 1.Fix a retaining rope bar in the pulley flanks of lifting hook, thereby prevent that steel rope from jumping out and the disorder cable phenomenon takes place from pulley groove.
But above-mentioned lifting hook is loading or during the dismounting steel rope, is all needing operation or dismounting retaining rope structure, the so not only concrete operations of inconvenient lifting hook, but also increased the labor content of field worker.
The utility model content
The purpose of this utility model is to provide a kind of lifting hook of three ward off rope support structures, it can prevent that steel rope from jumping out from pulley groove and disorder cable takes place, and need not dismounting and get final product reeve, thereby reduced the labor content of field worker, effectively raise work efficiency.
To achieve these goals, the lifting hook of a kind of three ward off rope support structures of the present utility model, it comprises pulley and places the suspension hook of pulley below, wherein, the left side of described pulley, right side and downside all are set with a ward off rope support, and described ward off rope support comprises a dull and stereotyped and dull and stereotyped vertically disposed rope blocking plate, wherein, the distance between adjacent two rope blocking plates is greater than the diameter of the cable wire end that twines on the pulley.
The lifting hook of three above-mentioned ward off rope support structures, wherein, described three ward off rope support centers all are positioned on the line of centers extended line of described pulley.
The lifting hook of three above-mentioned ward off rope support structures, wherein, the ward off rope support on described left side and right side upper end is separately installed with roller.
The lifting hook of three above-mentioned ward off rope support structures, wherein, described roller is the long cylinder roller.
The lifting hook of three above-mentioned ward off rope support structures, wherein, described ward off rope support is fixed on the described pulley by the sleeve pipe on the pulley.
The lifting hook of three above-mentioned ward off rope support structures, wherein, described ward off rope support is fixed on the described pulley by the mode of welding.
The lifting hook of three above-mentioned ward off rope support structures, wherein, described ward off rope support is formed from steel.
The lifting hook of three above-mentioned ward off rope support structures, wherein, described rope blocking plate surface scribbles lubricant.
Therefore, the lifting hook of three ward off rope support structures of the present utility model is by the left side at pulley, right side and downside all fixedly install a ward off rope support structure, preventing that steel rope is when pulley groove is jumped out, also realized the winding of carrying out steel rope of exempting to dismantle, thereby reduced the labor content of field worker greatly, effectively raised efficiency.

The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
In the utility model, the lifting hook of three ward off rope support structures comprises pulley 4 and places the suspension hook 3 of pulley below.In the left side of pulley 4, right side and downside all are provided with a ward off rope support 1, and its structure as shown in Figure 2.This ward off rope support 2 comprises a base plate 21, and is vertically set on the rope blocking plate 22 on the flat board.Can penetrate steel rope in order to guarantee need not dismantle, the distance between adjacent two rope blocking plates 22 need be greater than the diameter of the cable wire end that is twined on the pulley 4.
Fig. 3 and Fig. 4 are the side and the front schematic view of the lifting hook of three ward off rope support structures of the present utility model.As seen from the figure, the both sides that are arranged on pulley 4 of ward off rope support 2 symmetries on left side and right side, and on the extended line of the horizontal center line that is centered close to pulley 4 of ward off rope support 2.The ward off rope support 2 of downside then is positioned on the extended line of vertical center line of pulley 4.Thereby, on the side that is arranged on pulley 4 of above-mentioned three ward off rope support 2 symmetries.
In preferred embodiment of the present utility model, the upper end at the ward off rope support 2 on left side and right side is provided with a roller 1, is generally a long cylinder roller 1.This roller 1 is mainly used in the steel rope of winding on the anti-limited slip wheel 4 and the friction between the ward off rope support 2, thereby increases the flexibility of operation of the lifting hook of whole three ward off rope support structures, is of value to and increases work efficiency.In addition, in order to reduce the friction between steel rope and the pulley, can also on the surface of ward off rope support, scribble lubricant.
Usually, ward off rope support 2 is a steel.As shown in Figure 5, ward off rope support 2 is fixedly connected on the pulley 4 by the sleeve pipe 5 that is positioned on the pulley 4.Under this mounting structure, ward off rope support 2 can optionally be installed on pulley 4 or remove, so that be adapted to different working condition requirements.
In addition, this ward off rope support directly can also be welded on the pulley 4, thereby guarantee the steadiness of whole lifting hook structure.
Therefore, the lifting hook of three ward off rope support structures of the present utility model is by the left side at pulley, right side and downside all fixedly install a ward off rope support structure, preventing that steel rope is when pulley groove is jumped out, also realized the winding of carrying out steel rope of exempting to dismantle, thereby reduced the labor content of field worker greatly, effectively raised efficiency.
More than specific embodiment of the utility model is described in detail, but the utility model is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications that the lifting hook of these three ward off rope support structures is carried out and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.
