Description

The oblique sheave shaft pore structure of a kind of novel suspension hook

Technical field

The utility model relates to technical field of crane equipment, is specifically related to the oblique sheave shaft pore structure of a kind of novel suspension hook.

Background technology

Electric block, as a kind of material conveyance equipment, is widely used in industry-by-industry, and its relevant matching component is under the prerequisite of safety, reliability, and the requirement of the aspects such as its economy and maintainability is more and more higher.

The commonplace employing version of current electric hoist suspension hook sheave shaft inclined shaft is as shown in accompanying drawing 1,2; As shown in Figure 1, the end face 101,102 of this arrangement pulley wheels axle 1 is plane, shaft end adopts back-up ring 3 to locate, end cap 4 machined inclined hole to install sheave shaft 1, due to this arrangement pulley wheels axle 1 slant setting, cause axle head can not contact completely with boatswain chair 2, therefore reinforce at sheave shaft 1 two ends interpolation end cap 4, the hole of end cap 4 will be consistent with sheave shaft 1 angle of inclination, end cap 4 inclined hole is difficult to processing, complex structure, and shaft end adopts back-up ring 3 to be positioned by sheave shaft 1, back-up ring 3 tilts device reliability is reduced; As shown in Figure 2, this structure boatswain chair 5 has two places bending 501,502, adapt to pulley angle by bending boatswain chair 5, bending boatswain chair 5 is irregular for shape matching straight dress boatswain chair, also not easily processes, cost is higher, also have inconvenience during use, and boatswain chair restricts by bending angle, affect suspension hook overall appearance, not easily lay, in making and installation, also there is the problems such as difficult assembling.

For addressing these problems, the utility model proposes a kind of novel lifting hook pulley axial aperture structure, this structure is without the need to processing end cap inclined hole and bending boatswain chair, and cost is low, easily processes, and reliability is strong.

Utility model content

For above-mentioned the deficiencies in the prior art, the utility model provides the oblique sheave shaft pore structure of a kind of novel suspension hook, this kind of structure simple structure, without the need to processing end cap inclined hole and bending boatswain chair.

The utility model comprises door 6, sheave shaft 7, pulley 8, boatswain chair 9, baffle plate 10, first screw 11, second screw 12; Wherein boatswain chair 9 is two pieces, shape is flat, boatswain chair 9 and door 6 keeping parallelism, upper and lower boatswain chair 9 is parallel to each other and places and have hole 901,902, the inwall of two circular cavities 901,902 be skewed and also their internal diameter identical with sheave shaft 7 external diameter size; Upper surface 701 and the lower surface 702 of sheave shaft 7 are inclined-plane and are parallel to each other, and sheave shaft 7 angle of inclination and two circular cavities 901,902 angle of inclination are consistent, and the upper surface 701 of sheave shaft 7 and lower surface 702 are in same plane respectively with two pieces of boatswain chairs 9; Door 6 use the first screw 11 fix sheave shaft 7.

The beneficial effects of the utility model are: use straight boatswain chair, do not need processing inclined and bending boatswain chair, and make structure simple, difficulty of processing is low, and manufacturability is high, easily assembles, and cost is lower, and reliability is strong.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the first oblique sheave shaft pore structure figure of the prior art;

Fig. 2 is the oblique sheave shaft pore structure figure of the second of the prior art;

Fig. 3 is oblique sheave shaft pore structure figure described in the utility model.

Detailed description of the invention

For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described; Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment:

Fig. 3 is Novel inclined sheave shaft pore structure described in the utility model, comprises door 6, sheave shaft 7, pulley 8, boatswain chair 9, baffle plate 10, first screw 11, second screw 12; Wherein boatswain chair 9 is two pieces, shape is flat, boatswain chair 9 and door 6 keeping parallelism, upper and lower boatswain chair 9 is parallel to each other and places and have hole 901,902, the inwall of two circular cavities 901,902 be skewed and also their internal diameter identical with sheave shaft 7 external diameter size; Upper surface 701 and the lower surface 702 of sheave shaft 7 are inclined-plane and are parallel to each other, and sheave shaft 7 angle of inclination and two circular cavities 901,902 angle of inclination are consistent, and the upper surface 701 of sheave shaft 7 and lower surface 702 are in same plane respectively with two pieces of boatswain chairs 9; Door 6 use the first screw 11 fix sheave shaft 7.
