Abstract
The utility model relates to a pulley, in particular to a pulley for an elevator. The pulley for the elevator comprises a pulley body which is provided with a sliding groove, the sliding groove is formed in the outer circumferential face of the pulley body in a surrounding mode, a mounting hole is formed in the axial end face of the pulley body, at least two protruding ribs are arranged in the sliding groove of the pulley body, a space between the two protruding ribs is a steel rope placing space, and a plurality of through holes are formed in the side faces of the protruding ribs. The pulley for the elevator is stable in transmission and simple in structure.
Description
Technical field
The utility model relates to a kind of pulley, particularly a kind of elevator pulley.
Background technique
The lifting of elevator mainly relies on cooperating of steel cable and sheave block, if steel cable is by coming off on the pulley, then elevator can't move.Traditional pulley is mainly by wheel body and be opened in chute on the wheel body outer circumferential face, and the cross section of chute is arcuation, and steel cable is as easy as rolling off a log by skidding off in the chute in running, has bigger potential safety hazard.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of transmission stable, simple in structure elevator pulley.
For achieving the above object, the utility model provides following technological scheme: a kind of elevator pulley, include wheel body, offer the chute that arranges around its outer circumferential face on the wheel body, offer mounting hole on the axial end of wheel body, it is characterized in that: be provided with at least two convex tendons in the chute of described wheel body, the space between two convex tendons is the steel cable placement space, and the side of each convex tendon offers some through holes on respectively.
Adopt technique scheme, by at least two convex tendons are set in the chute of wheel body, and the steel cable placement space in the space between each convex tendon, after arranging like this, steel cable can be stable be in operation in the steel cable placement space, in running, be subjected to after the stopping of convex tendon just not can be easily by skidding off in the chute, thereby existing potential safety hazard when having eliminated the elevator operation.The setting that the side of each convex tendon is gone up some through holes respectively can have the effect of absorption to steel cable, the stability when further having guaranteed the steel cable operation.
The utility model further is set to: each convex tendon is provided with short slot towards the inner side surface of steel cable placement space and the joining place of chute.
Adopt technique scheme, the area that the bottom that has increased the steel cable placement space is set of short slot makes the operation of steel cable more stable.
The utility model further is set to: a side of wheel body mounting hole is provided with keyway.
Adopt technique scheme, the installation that has made things convenient for pulley and motor is set like this.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's schematic perspective view;
Fig. 2 is the utility model embodiment's structural representation.
Embodiment
A kind of elevator pulley as shown in Figure 1 and Figure 2, include wheel body 1, offer the chute 11 that arranges around its outer circumferential face on the wheel body 1, offer mounting hole 12 on the axial end of wheel body 1, one side of mounting hole 12 arranges keyway 13, can make things convenient for the installation between wheel body 1 and the motor like this.The space that is provided with in the chute 11 of wheel body 1 between at least two convex tendons 2, two convex tendons 2 is steel cable placement space 21, and the side of each convex tendon 2 offers some through holes 22 on respectively.In the such scheme, by at least two convex tendons 2 are set in the chute 11 of wheel body 1, and the steel cable placement space 21 in the space between each convex tendon 2, after arranging like this, steel cable can be stable be in operation in the steel cable placement space 21, in running, be subjected to after the stopping of convex tendon 2 just not can be easily by skidding off in the chute 11, thereby existing potential safety hazard when having eliminated the elevator operation.The setting of some through holes 22 can have the effect of absorption to steel cable on the side of each convex tendon 2, the stability when further having guaranteed the steel cable operation.Need to prove that the cross section of convex tendon 2 can be triangular shape, also can be rectangle.
In the utility model embodiment, in order to increase the area of steel cable placement space 21 bottoms, make the operation of steel cable more stable.Each convex tendon 2 is provided with short slot 23 towards the inner side surface of steel cable placement space 21 and the joining place of chute 1.
Claims (3)
1. elevator pulley, include wheel body, offer the chute that arranges around its outer circumferential face on the wheel body, offer mounting hole on the axial end of wheel body, it is characterized in that: be provided with at least two convex tendons in the chute of described wheel body, space between two convex tendons is the steel cable placement space, and the side of each convex tendon offers some through holes on respectively.
2. elevator pulley according to claim 1, it is characterized in that: described each convex tendon is provided with short slot towards the inner side surface of steel cable placement space and the joining place of chute.
