Utility model content
The technical matters that the utility model solves is to provide a kind of safer pulley suspension hook.
The utility model solves the technical scheme that its technical matters adopts: pulley suspension hook, comprise housing, hanging parts and head pulley, described hanging parts are arranged on the lower end of housing, described head pulley is rotating to be arranged on housing, also comprise auxiliary pulley, described auxiliary pulley is rotating to be arranged on housing, and auxiliary pulley is positioned at the below of head pulley, the chute of described head pulley and the mutual corresponding matching of chute of auxiliary pulley.
Further: the left and right sides corresponding with auxiliary pulley on housing is respectively arranged with chute, be provided with slide block moving up and down in chute, the support end axle of auxiliary pulley both sides is rotating to be respectively arranged on the slide block of respective side; Also comprise elastic component, one end of described elastic component is connected with the bottom of slide block, and the other end is against the bottom of chute.
Further: the cross-sectional plane of the chute of head pulley is identical with the shape of cross section of the chute of auxiliary pulley.
Further: described elastic component is spring.
Further: described hanging parts are suspension hook.
Further: the rotating lower end being arranged on housing of described suspension hook.
Further: the opening part of suspension hook is provided with opening sealing clamp.
The beneficial effects of the utility model are: by the corresponding matching of the chute of auxiliary pulley and the chute of head pulley, improve the spacing constraint to hawser by auxiliary pulley, reduce the situation occurring de-wheel or card wheel; And then the safety of pulley suspension hook can be improved.In addition, auxiliary pulley also can up-down adjustment automatically by arranging that corresponding structure realizes, and makes pulley suspension hook can adapt to the hawser of different size.
Accompanying drawing explanation
Fig. 1 is the front view of pulley suspension hook described in the utility model;
Fig. 2 is the lateral plan of pulley suspension hook described in the utility model;
Fig. 3 is the enlarged diagram of regional area A in Fig. 1;
Be labeled as in figure: housing 1, hanging parts 2, head pulley 3, auxiliary pulley 4, support end axle 41, chute 5, slide block 6, elastic component 7, opening sealing clamp 8, crack 9, spacing preiection 10.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1 to Figure 3, pulley suspension hook described in the utility model, comprise housing 1, hanging parts 2 and head pulley 3, described hanging parts 2 are arranged on the lower end of housing 1, described head pulley 3 is rotating to be arranged on housing 1, also comprises auxiliary pulley 4, and described auxiliary pulley 4 is rotating to be arranged on housing 1, and auxiliary pulley 4 is positioned at the below of head pulley 3, the chute of head pulley 3 and the mutual corresponding matching of chute of auxiliary pulley 4.
Wherein, the chute of so-called head pulley 3 and the mutual corresponding matching of chute of auxiliary pulley 4, refer to the crack 9 that can be formed after being matched by the chute of head pulley 3 and the chute of auxiliary pulley 4 and pass for hawser; And after installing, the both sides up and down of hawser should be subject to the restriction of the chute of head pulley 3 and the chute of auxiliary pulley 4 respectively; Such safety that could improve pulley suspension hook.Head pulley 3 should be positioned at the top of auxiliary pulley 4, because head pulley 3 needs to bear whole pulley suspension hook and hangs over the gravity of device on pulley suspension hook etc., auxiliary pulley 4 then only plays the restriction to hawser.
As for the chute of head pulley 3 and the mutual corresponding matching of chute of auxiliary pulley 4, optimum is set to as shown in Figures 1 and 2, the i.e. chute of head pulley 3 and the chute in the vertical direction correspondence of auxiliary pulley 4, and the pivot center of the pivot center of head pulley 3 and auxiliary pulley 4 be level to, and to be parallel to each other.
In addition, can coordinate with the hawser of different-diameter size to make pulley suspension hook, the left and right sides that can be corresponding with auxiliary pulley 4 on housing 1 is respectively arranged with chute 5, in chute 5, be provided with slide block 6 moving up and down, the support end axle 41 of auxiliary pulley 4 both sides is rotating to be respectively arranged on the slide block 6 of respective side; Also comprise elastic component 7, one end of described elastic component 7 is connected with the bottom of slide block 6, and the other end is against the bottom of chute 5.Like this by the adjustment of elastic component 7, can realize changing the relative position between head pulley 3 and auxiliary pulley 4, and then change the size of crack 9, to adapt to the hawser of different size.The effect of elastic component 7 realizes the self-adaptative adjustment to slide block 6, and after usually installing, elastic component 7 keeps compressive state.Elastic component 7 can adopt variously has elastomeric part, usually preferably adopts spring.
When adopting spring as elastic component 7, the two ends of spring can be enclosed within the spacing preiection 10 of the bottom spacing preiection 10 of slide block 6 and the bottom of chute 5 respectively, making the easier for installation of spring like this, also can preventing spring from easily being occurred the situation of distortion or distortion when compressing simultaneously.
In theory, the size of head pulley 3 and auxiliary pulley 4 is any relation not, and consider that head pulley 3 will bear usually larger stressed, the diameter of the auxiliary pulley of ratio 4 that therefore usually the diameter of head pulley 3 can be done is larger.Consider cooperatively interacting between the chute of head pulley 3 and the chute of auxiliary pulley 4, preferably that the cross-sectional plane of the chute of head pulley 3 is identical with the shape of cross section of the chute of auxiliary pulley 4, the two can form roughly symmetrical crack 9 after coordinating like this, makes the matching relationship of itself and hawser better.As the cross-sectional plane of the chute of head pulley 3 and the cross-sectional plane of the chute of auxiliary pulley 4 being arranged to the identical half slot structure of radius, as shown in Figure 2.
In addition, hanging parts 2 are the structures for hanging other parts or device, and hanging parts 2 itself can be the structures on housing 1, also can be mounted in the parts on housing 1, as being arranged to a suspension hook.In addition, for improving the alerting ability of above-mentioned suspension hook, usually can by rotating for the suspension hook lower end being arranged on housing 1.As shown in FIG..
In addition, in order to improve the safety of suspension hook further, also the opening part of suspension hook is provided with opening sealing clamp 8.
