Abstract

The utility model discloses a durable pulley for an elevator tractor. The durable pulley comprises a pulley body (2) and is characterized in that an inlet pipe (4) and an outlet pipe (6) for enabling a haulage rope to penetrate in and out are arranged on the pulley body (2), sponge bodies (8) which are in a contact with the haulage rope are arranged in the inlet pipe (4) and the outlet pipe (6), an oil storage box (10) is installed on the pulley body (2), an oil tube (12) is mounted at the bottom of the oil storage box (10), and the oil tube (12) is communicated with the sponge bodies (8). The durable pulley for the elevator tractor has the advantages of being simple in structure and good in lubrication effect.

Description

Elevator traction machine durable type pulley

Technical field

The utility model relates to a kind of pulley, relates in particular to a kind of elevator traction machine durable type pulley.

Background technology

Elevator, especially the elevator of vertical lift is to rely on the pulling force of many hauling ropes to do the vertical takeoff and landing (VTOL) operation aloft, in case hauling rope fracture in operational process, might cause casualties, the consequences such as device damage, therefore reduce the hauling rope wearing and tearing, can prevent the hauling rope fracture by actv. the service life that prolongs hauling rope, at present, the means that reduce the hauling rope wearing and tearing are varied, wherein comparatively commonly used is the oil lubrication that increases between hauling rope and the pulley, although this kind method is effectively simple, but waste lubricating oil, use too much lubricating oil not only can increase the maintenance cost of elevator, also pollute the environment, so the urgent hope of people can reduce by other means the wearing and tearing of hauling rope.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, and lubricant effect is elevator traction machine durable type pulley preferably.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of elevator traction machine durable type pulley, comprise the pulley body, have on the described pulley body for hauling rope and penetrate induction pipe and the outlet pipe that passes, be provided with in described induction pipe and the described outlet pipe and the contacted cavernous body of hauling rope, on the described pulley body oil storage box is installed, the bottom of described oil storage box is provided with oil pipe, and described oil pipe communicates with described cavernous body.

Described cavernous body is the ring-type cavernous body, has the hole of passing for steel wire on the described cavernous body.

Described oil storage box is transparent oil storage box.

Compared with prior art, the beneficial effects of the utility model are:

Because elevator traction machine of the present utility model includes induction pipe and outlet pipe with the durable type pulley, be respectively arranged with cavernous body in this induction pipe and the outlet pipe, this cavernous body communicates with oil storage box by oil pipe, the cavernous body that is positioned at induction pipe when hauling rope when induction pipe penetrates just can be coated in lubricating oil the surface of hauling rope uniformly, when being contacted, hauling rope slideway each and on the pulley body all has enough lubricating oils, thereby has preferably lubricant effect, well avoided causing because of lack of lubrication the defective of hauling rope wearing and tearing, in addition, the cavernous body that is positioned at outlet pipe when hauling rope when outlet pipe passes can absorb lubricating oil unnecessary on the hauling rope, not only fuel-efficient, simultaneously can also avoid unnecessary lubricant pollution environment, therefore the utility model is simple in structure, and lubricant effect is better.

Description of drawings

Describe the utility model in detail below in conjunction with drawings and embodiments:

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

Among the figure: pulley body 2, hauling rope 3, induction pipe 4, outlet pipe 6 cavernous bodies 8, oil storage box 10, oil pipe 12.

The specific embodiment

As shown in Figure 1, a kind of elevator traction machine durable type pulley of the present utility model, comprise pulley body 2, have on this pulley body 2 for hauling rope 3 and penetrate induction pipe 4 and the outlet pipe 6 that passes, be provided with in this induction pipe 4 and the outlet pipe 6 and hauling rope 3 contacted cavernous bodies 8, oil storage box 10 is installed on the pulley body 2, and the bottom of this oil storage box 10 is provided with oil pipe 12, and cavernous body 8 communicates with oil storage box 10 by oil pipe 12.

The utlity model has preferably oiling effect for making, preferred cavernous body 8 is the ring-type cavernous body, has the hole of passing for steel wire on the cavernous body 8; Be the surplus that makes the elevator maintenance personnel can easier observe lubricating oil, oil storage box 10 is transparent oil storage box.

Action principle of the present utility model is: the cavernous body 8 that is positioned at induction pipe 4 when hauling rope 3 when induction pipe 4 penetrates just can be coated in lubricating oil the surface of hauling rope 3 uniformly, when being contacted, hauling rope 3 slideways each and on the pulley body 2 all have enough lubricating oils, thereby has preferably lubricant effect, well avoided causing because of lack of lubrication the defective of hauling rope 3 wearing and tearing, in addition, the cavernous body 8 that is positioned at outlet pipe 6 when hauling rope 3 when outlet pipe 6 passes can absorb lubricating oil unnecessary on the hauling rope 3, not only fuel-efficient, can also avoid unnecessary lubricant pollution environment simultaneously.

In sum, the utility model is simple in structure, and lubricant effect is better.

The above only is preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
