Description

A kind of jigger wheel

Technical field

The utility model relates to parts in a kind of elevator traction machine, a kind of jigger wheel specifically.

Background technology

Jigger wheel is parts in elevator traction machine, when elevator breaks down, needs manually to be set on the center shaft of elevator by jigger wheel, then rotates this jigger wheel to control elevator lifting.On existing market, the general jigger wheel used is iron jigger wheel, its structure comprises a smooth disk and a rotary axle box, a through hole is provided with in the middle of this smooth disk, rotary axle box is bolted on the lead to the hole site of this disk, because the center shaft shape of different elevator is different, be carry out meet requirements by being equipped with difform rotary axle box at present.There is two problems in such jigger wheel, and the first, owing to being iron jigger wheel, and be the center shaft shape carrying out satisfied different elevator by being equipped with difform rotary axle box at present, not only cost is high, and there is volume heaviness, uses inconvenient shortcoming; The second, because its structure adopts smooth circular plate, manually easily skidding with during hand rolling disc wheel, have that labour intensity is large, the shortcoming of poor safety performance.

Utility model content

For the problems referred to above, the problem that the utility model quasi-solution is determined is to provide a kind of rational in infrastructure, cost is low, lightweight, bulk strength is high and easy to use jigger wheel, not only greatly reduce the labour intensity of staff, and greatly improve the safety performance of staff.

For achieving the above object, the utility model is by the following technical solutions: a kind of jigger wheel, this jigger wheel is one-body molded, its material is plastics, structure comprises a disk, described disk cylindrical circle Monday is provided with protruding annular region, the upper surface of described annular region and lower surface are provided with finger recess all uniformly, and the finger recess one_to_one corresponding on described annular region upper surface and lower surface, the middle position of described disk is provided with a rolling bearing, a through hole is provided with in the middle of described rolling bearing, the shape of cross section of described rolling bearing and the shape of cross section of described through hole are hexagon, described disk upper surface and lower surface are equipped with three reinforced ribs, and three reinforced rib one_to_one corresponding on described disk upper surface and lower surface, disk is divided into three regions of area equation.

As preferably, described disk is also provided with a hanging hole.

Effective achievement of the present utility model: the utility model is rational in infrastructure, due to this jigger wheel is designed to one-body molded, material is adopted as plastics, and be all provided with three reinforced ribs at the upper surface of disk and lower surface, disk is divided into three regions of area equation, there is low, lightweight, the easy to use and feature that bulk strength is high of cost; The annular region upper surface of disk cylindrical circle Monday and lower surface are provided with finger recess all uniformly, staff is made to avoid occurring skidding in hand rolling disc wheel, not only greatly reduce the labour intensity of staff, and greatly improve the safety performance of staff; The unique design of rolling bearing, during use, does not need to change rolling bearing according to the center shaft shape of elevator again, as long as fix difform sleeve with glue in the through hole of rolling bearing, convenient and swift; Moreover the design of hanging hole, the jigger wheel do not used can be allowed to hang over assigned address, be convenient to take.

In sum, the utility model has rational in infrastructure, that cost is low, lightweight, bulk strength is high and easy to use jigger wheel, not only greatly reduces the labour intensity of staff, and greatly improves the safety performance of staff.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1-disk, 2-annular region, 3-finger recess, 4-rolling bearing, 5-through hole, 6-reinforced rib, 7-hanging hole.

Detailed description of the invention

In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.

As shown in Figure 1, the utility model discloses a kind of jigger wheel, this jigger wheel is one-body molded, its material is plastics, structure comprises a disk 1, disk 1 cylindrical circle Monday is provided with protruding annular region 2, the upper surface of annular region 2 and lower surface are provided with finger recess 3 all uniformly, and finger recess 3 one_to_one corresponding on annular region 2 upper surface and lower surface, the middle position of disk 1 is provided with a rolling bearing 4, a through hole 5 is provided with in the middle of rolling bearing 4, the shape of cross section of rolling bearing 4 and the shape of cross section of through hole 5 are hexagon, disk 1 upper surface and lower surface are equipped with three reinforced ribs 6, and three reinforced rib 6 one_to_one corresponding on disk 1 upper surface and lower surface, disk 1 is divided into three regions of area equation, disk 1 is also provided with a hanging hole 7.

The utility model is rational in infrastructure, due to this jigger wheel is designed to one-body molded, material is adopted as plastics, and be all provided with three reinforced ribs 6 at the upper surface of disk 1 and lower surface, disk 1 is divided into three regions of area equation, there is low, lightweight, the easy to use and feature that bulk strength is high of cost; Annular region 2 upper surface of disk 1 cylindrical circle Monday and lower surface are provided with finger recess 3 all uniformly, staff is made to avoid occurring skidding in hand rolling disc wheel, not only greatly reduce the labour intensity of staff, and greatly improve the safety performance of staff; The unique design of rolling bearing 4, during use, does not need to change rolling bearing 4 according to the center shaft shape of elevator again, as long as fix difform sleeve with glue in the through hole 5 of rolling bearing 4, has that cost is low, conveniently feature; Moreover the design of hanging hole 7, the jigger wheel do not used can be hung over assigned address, be convenient to take.

Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.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 should belong to the scope of the utility model protection.
