Abstract
The utility model provides a cross beam with a positioning function for a lifting hook, which is used for penetration by the lifting hook. The cross beam comprises a central through hole which is fixedly provided with a copper sleeve at the lower end. The copper sleeve is closely connected with the central through hole. According to the utility model, the cross beam with positioning function for lifting hook effectively restrains transverse movement of the lifting hook through inlaying the copper sleeve at the lower part, thereby preventing friction between the lifting hook and the inner hole of the cross beam and performing good positioning function. The cross beam with the structure has the following advantages: simple structure, convenient operation, ensured flexible rotation in lifting by the lifting hook, greatly facilitated accurate positioning of the lifted object, prevention for steel wire winding in lifting, and effectively ensured safety in construction operation of a crane.

Background technology
In hoisting crane machinery, lifting hook is realized the lifting and the decline of weight by the winding of steel rope.Lifting hook is used for directly carrying the quality of weight.Thereby the structure of lifting hook has fundamental influence for whole hoisting crane performance.
Fig. 1 is the structural representation of lifting hook in the prior art.As seen from the figure, this lifting hook mainly comprises nut 1, bearing 2, crossbeam 3 and suspension hook 4.Wherein, after suspension hook 4 passes crossbeam 3 and bearing 2, be connected with nut 1, thereby constituted the basic structure of lifting hook by the mode that is threaded.In this structure, suspension hook 4 can be rotated around vertical direction.
Yet, in said structure, because bearing 2 is a split-type structural; be installed between crossbeam 3 and the nut 1; and suspension hook 4 situation of unbalance loading occurs through regular meeting, thereby suspension hook 4 is unavoidable in hanging the process of carrying rubs with crossbeam 3 endoporus, to such an extent as to the inflexible problem of suspension hook 4 rotations occurs.Suspension hook rotates the dumb difficulty in place that then can cause hanging loading, even disorder cable phenomenons such as steel rope twines mutually can take place.This will increase the security hidden trouble in the hoisting crane lifting operating process undoubtedly.Thereby, be badly in need of a kind of device that can play the role of positioning to lifting hook, so that its flexible rotation adapts to hoisting crane concrete operations need of practice.
The utility model content
The purpose of this utility model is to provide a kind of lifting hook crossbeam that plays the role of positioning, but its actv. is avoided the friction between crane hook and the crossbeam endoporus, thus the problem of fundamentally having avoided suspension hook not rotate flexibly.
To achieve these goals, a kind of lifting hook crossbeam that plays the role of positioning of the present utility model, it passes for the lifting hook suspension hook, comprises a center through hole, and the lower end of described center through hole is fixed with a copper sheathing, described copper sheathing and described center through hole leak-tight joint.
With the crossbeam that plays the role of positioning, wherein, described crossbeam is a steel according to above-mentioned lifting hook.
According to the above-mentioned lifting hook crossbeam that plays the role of positioning, wherein, the outside face of described center through hole scribbles lubricant.
According to the above-mentioned lifting hook crossbeam that plays the role of positioning, wherein, respectively there is an annular groove at described crossbeam two ends.
According to the above-mentioned lifting hook crossbeam that plays the role of positioning, wherein, described crossbeam center through hole inwall is smooth.
According to the above-mentioned lifting hook crossbeam that plays the role of positioning, wherein, described copper sheathing is embedded in the lower end of described center through hole.
In addition, the utility model also provides a kind of lifting hook, it comprises suspension hook, crossbeam, bearing and nut, wherein, described crossbeam comprises a center through hole, and the lower end of described center through hole is fixed with a copper sheathing, described copper sheathing and described center through hole leak-tight joint, described suspension hook passes the center through hole and the described bearing of described crossbeam, captives joint by screw thread with nut.
According to above-mentioned lifting hook, wherein, described copper sheathing is embedded in the lower end of described center through hole.
According to above-mentioned lifting hook, wherein, respectively there is an annular groove at described crossbeam two ends.
According to above-mentioned lifting hook, wherein, the outside face of described center through hole scribbles lubricant.
Therefore, by inlay a copper sheathing in the bottom, actv. has limited the side travel of suspension hook to a kind of lifting hook of the present utility model, thereby has avoided the friction between suspension hook and the crossbeam endoporus, has played good positioning action with the crossbeam that plays the role of positioning.The beam structure of this structure is simple, and is easy to operate, and guaranteed that suspension hook hangs the flexible rotation when carrying, and greatly facilitate and hang the accurately in place of loading, the generation of steel rope wrapping phenomena when having avoided lifting, actv. has guaranteed the safety of hoisting crane construction operation.
Description of drawings
Fig. 1 is the structural representation of lifting hook in the prior art;
Fig. 2 is a kind of lifting hook structural representation of the crossbeam that plays the role of positioning in the utility model.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 2 is the structural representation of lifting hook of the present utility model with the crossbeam that plays the role of positioning.This crossbeam 31 is used for passing through for the lifting hook suspension hook, to play firm effect.Therefore, as shown in Figure 2, this crossbeam 31 position in the central is provided with a center through hole 33, and the lower end of this center through hole 33 is set with a copper sheathing 32.Wherein, copper sheathing 32 is embedded in the lower end of center through hole 33.Hang when carrying operation at hoisting crane, copper sheathing 32 can limit the side travel that passes suspension hook wherein, the starting positioning action, thus avoided friction between suspension hook and the crossbeam endoporus, actv. has avoided suspension hook to rotate inflexible problem.
In a preferred embodiment of the present utility model, the inwall of center through hole 33 this as smooth structure.Can also scribble lubricant at the outside face of center through hole 33, as lubricating oil, grease, graphite etc. are with the slickness of further assurance center through hole 33 inwalls.
In another preferred embodiment of the present utility model, this crossbeam is a steel, its smooth surface.And respectively there is an annular groove at the crossbeam two ends, and this annular groove is used for the miscellaneous part of this crossbeam and hoisting crane is fixedly linked.
According to the crossbeam of said structure, the utility model can also provide a kind of lifting hook, and it includes the crossbeam of said structure, thereby makes this lifting hook can realize rotating flexibly, has guaranteed the safety of concrete operations.
