Abstract
According to one embodiment, a cleaning head for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system is provided. The at least one sheave includes a plurality of grooves for receiving each of the hoisting belts. The cleaning head comprises a base plate and a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate. The cleaning head may be used to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once.
Claims18
A cleaning head for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head may be used to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once;
- wherein the number of wipers corresponds to the number of hoisting belts.
A cleaning head for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head may be used to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once;
- wherein the upper end of the base plate is bent at an angle A with respect to the rest of the base plate, and
- wherein the wipers are each sandwiched between the upper end of the base plate and respective fixing plates bolted onto the upper end of the base plate so that the wipers project outwards from the base plate at the angle A.
A cleaning head for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head may be used to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once;
- wherein each of the wipers comprise an elastic plate and a cleaning sheet wrapped around the elastic plate.
A cleaning head for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head may be used to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once;
- wherein the at least one sheave is an idler sheave.
A cleaning device for cleaning a plurality of hoisting belts and/or at least one sheave of an elevator system, the at least one sheave including a plurality of grooves for receiving each of the hoisting belts, comprising:
- an attachment plate which may be fixed to a machine casing;
- at least one L-shaped first bracket which may be adjustably fixed to the attachment plate;
- at least one L-shaped second bracket which may be adjustably fixed to the first bracket;
- and
- a cleaning head which may be fixed to the second bracket, including:
- a base plate;
- and
- a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- wherein the cleaning head is positioned to clean the plurality of hoisting belts at once and/or the plurality of grooves of the at least one sheave at once.
A method for installing a cleaning device in an elevator system, comprising:
- fixing an attachment plate and at least one L-shaped first bracket to a machine casing;
- fixing at least one L-shaped second bracket to the first bracket;
- fixing a cleaning head to the second bracket, the cleaning head including a base plate and a plurality of wipers fixed to an upper end of the base plate to project outwards from the base plate;
- and
- adjusting the first bracket and the second bracket so that the cleaning head applies an adequate pressure to a plurality of hoisting belts at once or to a plurality of grooves of at least one sheave at once.
