Abstract
The utility model relates to a handrail driving device of automatic staircase belonging to the technical field of the automatic staircase. The center of a disc-shaped traction wheel is provided with a through-hole, the diameter of which is 44mm. A cylindrical protruding part is vertically connected with the part of the traction wheel, which is close to the through-hole, and the thickness of the protruding part is 30mm. The utility model has advantages of simple structure, convenient installation and use, and costs saving.
Description
Technical field
The utility model relates to the technical field of escalator.
Background technology
Traction sheave is a mechanical part commonly used in the escalator, mainly be to drive traction sheave by actuating unit, hoist ropes is wrapped on traction sheave and the track adjusting wheel, and hoisting motor rotates by driving traction sheave after the retarder speed change, by hoist ropes and the fricative tractive force of traction sheave, reach the transportation purpose.Therefore realize the cage lifter of vertical uplink and downlink, not only be wound with hoist ropes on the traction sheave of use, and be connected with brake equipment, stop the rotation of traction sheave under special circumstances by force, more complicated structurally.
The traction sheave that uses on escalator at present generally is the structure of directly having diverted from one use to another the vertical lift elevator, because escalator has certain gradient, so the requirement height that the intensity and the braking effect of traction sheave required not have the vertical lift elevator.Directly use the traction sheave structure of vertical lift elevator simultaneously, install and maintenance inconvenience.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and it is convenient to install and overhaul, and saves the escalator traction sheave of cost.
A kind of escalator traction sheave, the center of discoid traction sheave body is provided with through hole, and the diameter of described through hole is 44mm, and near the columniform protruding part of vertical connection on the traction sheave body of through hole, the thickness of described protruding part is 30mm.
6 auxiliary holes evenly are set on the circumference of the utility model traction sheave body.
The utility model adopts technique scheme, and compared with prior art have following advantage: traction sheave of the present utility model is processed into the workpiece of fixed measure under standard compliant situation, simple in structure, is useful for specific environment for use, and it is convenient to install and overhaul.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1 and Figure 2, a kind of escalator traction sheave, the center of discoid traction sheave body 1 is provided with through hole 2, and the diameter of described through hole 2 is 44mm, near the columniform protruding part 3 of vertical connection on the traction sheave body 1 of through hole 2, the thickness of described protruding part 3 is 30mm.
6 auxiliary holes 4 evenly are set on the circumference of the utility model traction sheave body 1.
Claims (2)
1. escalator traction sheave, the center that it is characterized in that discoid traction sheave body (1) is provided with through hole (2), the diameter of described through hole (2) is 44mm, go up the vertical columniform protruding part (3) that connects near the traction sheave body (1) of through hole (2), the thickness of described protruding part (3) is 30mm.
