Abstract
The utility model relates to an elevator rope sheave structure, including the rope sheave main part the side of rope sheave main part be equipped with the V type recess that is used for placing the rope the rope sheave main part in the middle of be equipped with the bearing the side of V type recess on be equipped with a plurality of ball recesses the ball recess in be equipped with the ball, the ball at ball recess internal rotation. After having adopted above -mentioned structure, through the ball structure can be fine with the rope restriction in V type recess, be difficult to drop, the ball can rotate moreover, reduces the rope to the wearing and tearing of ball, after a ball took place to damage, other balls can normally be worked, owing to being spaced distribution ball, the rope can be inserted simple to operate, simple structure in the very convenient clearance of passing through between the ball to the life of rope sheave can be prolonged, the cycle of maintaining is increased.
Description
Technical field
This utility model relates to elevator and produces and manufacturing technology industry, especially relates to the elevator rope pulley structure of a kind of elevator.
Background technology
Elevator rope pulley is the conventional components in elevator landing door system, and it acts primarily as weight rope or the guiding of miscellaneous part rope or draw in whole elevator landing door.The opening or close of elevator landing door system middle level door is closed and is produced certain vibration effect to the layer door system in whole service, and elevator rope pulley does not carry out spacing position limiting structure to its interior rope in existing elevator door technology, therefore during elevator motion, between rope and the rope sheave of elevator, relaxation occurs, rope is easy to come off, affect the properly functioning of elevator, security incident the most easily occurs, and keeps in repair very inconvenient.
Utility model content
Even if technical problem to be solved in the utility model is to provide a kind of elevator rope pulley structure lax safety also not come off occur.
The technical scheme in the invention for solving the technical problem is: a kind of elevator rope pulley structure, including rope sheave main body, the V-type groove for placing rope it is provided with in the side of described rope sheave main body, it is provided with bearing in the middle of described rope sheave main body, the side of described V-type groove is provided with some ball grooves, being provided with ball in described ball groove, described ball rotates in ball groove.
The most concrete, described ball is resilient balls.
The most concrete, it is provided with wearing layer in described V-type groove.
The most concrete, the end face of described rope sheave main body is provided with the cell body of indent, is provided with some reinforcements in described cell body.
The beneficial effects of the utility model are: after have employed said structure, can be well limited in V-type groove by rope by roll structure, it is not easy to come off, and ball can rotate, reducing the rope abrasion to ball, after a ball is damaged, other balls can normally work, owing to being the distribution ball at interval, rope can be inserted by the gap between ball very easily, easy for installation, simple in construction, and the service life of rope sheave can be extended, increase the cycle of maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, rope sheave main body；2, V-type groove；3, bearing；4, ball；5, wearing layer；6, cell body；7, reinforcement.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is explained in detail.
A kind of elevator rope pulley structure as shown in Figure 1, including rope sheave main body 1, the V-type groove 2 for placing rope it is provided with in the side of described rope sheave main body 1, in the middle of described rope sheave main body 1, it is provided with bearing 3, the side of described V-type groove 2 is provided with some ball grooves, in described ball groove, is provided with ball 4, described ball 4 rotates in ball groove, realize rolling friction by rope and ball 4, reduce the infringement of friction, extend the service life of rope sheave；Described ball 4 is resilient balls, can be directly pressed into rope at V-type groove 2 very easily by resilient balls；It is provided with wearing layer 5 in described V-type groove 2, increases the wearability of rope sheave, improve the service life of rope sheave；The end face of described rope sheave main body 1 is provided with the cell body 6 of indent, alleviates the overall weight of rope sheave, is provided with some reinforcements 7 in described cell body 6, on the premise of alleviating rope sheave overall weight, improves the intensity of rope sheave.
The use of ball 4, the position of the rope both limited is not easy to come off, and can reduce the friction of rope and ball 4, improves the service life of rope sheave, adds maintenance cycle.
It is emphasized that: be the most only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, every any simple modification, equivalent variations and modification made above example according to technical spirit of the present utility model, all still falls within the range of technical solutions of the utility model.
