- the outer periphery of the pressing roller has an arc groove that engages with the rope. Therefore, the contact area of the pressing roller with the rope increases, and the frictional force between the pressing roller and the rope can be increased.
- the outer periphery of the pressing roller is made of an elastic material. ing. That is, the outer periphery of the pressing roller can be transformed into an arc following the circumference of the rope. Therefore, the contact area of the pressing roller with the rope increases, and the frictional force between the pressing roller and the rope can be increased.
- the pressing roller is movable with respect to the rope. Therefore, it can be adapted to various rope diameters.
- a belt wound around a pair of pressing rollers is provided, and the pair of pressing rollers presses the rope against the outer peripheral surface of the sheave via the belt between the pair of pressing rollers. ing. Therefore, the contact area between the pressing roller and the rope via the belt increases, and the frictional force between the pressing roller and the rope via the belt can be increased.
- FIG. 1 is a diagram showing a first embodiment of the present invention.
- FIG. 2 is a detailed sectional view of a pressing roller portion according to the first embodiment of the present invention.
- FIG. 3 is a diagram of another example of the pressing roller according to the present invention.
- FIG. 4 is a diagram showing a second embodiment of the present invention.
- FIG. 5 is a diagram showing a conventional traction-type elevator hoisting device. BEST MODE FOR CARRYING OUT THE INVENTION
- reference numeral 100 denotes a hoisting device for an elevator used in a traction-type elevator device.
- the fixing member 10 is attached to a fixing point of the traction-type elevator device.
- the rotation of the motor (not shown) is transmitted to the input unit 11 of the sheave 11 via a speed reducer (not shown). That is, the sheave 11 is connected to the motor and rotated.
- the rope 12 is wound around the groove 13 on the outer peripheral surface 13 of the sieve 11 to raise and lower the elevator 14.
- the elevator is connected to one of the suspended ropes.
- the counterweight 15 has a pair of pressing rollers 16 connected to the other suspended rope 12, and a pair of pressing rollers 16 are arranged substantially symmetrically with respect to the rotation center of the sheave 11, and the rope 12 is connected to the sheave 1. Press against the outer peripheral surface 1 3 of 1.
- the pair of pressing rollers 16 are arranged substantially symmetrically with respect to the upper and lower sides including the rotation center of the sheave 11.
- the outer periphery of the pair of pressing rollers 16 has an arcuate groove 17 that engages with the rope 11.
- Each pressing roller 16 is rotatably supported on a shaft 18 (non-rotating object) via a pair of bearings 19.
- the spring 20 presses each pressing roller 16 against the rope 12. Since each spring 20 can expand and contract, each pressing roller can move with respect to the rope 16.
- the pressing force of each pressing roller 16 to the rope 12 is adjusted. be able to.
- the pressing force of each pressing roller 16 on the rope 12 can be appropriately changed.
- the shaft retaining ring 23 is used for positioning the pair of bearings 19 and for preventing the bearing from coming off.
- the pair of pressing rollers 16 always press the rope 12 against the outer peripheral surface of the tube 1 by the spring 20. That is, the frictional force between the outer peripheral surface of the sheave 1 and the outer peripheral surface of the rope 12 is increased by the pair of pressing rollers 16. Therefore, the weight of the elevator car 3 and the counterweight 4 can be reduced. (Other examples of pressing roller)
- each pressing roller 200 has a cylindrical elastic body 202 such as rubber or silicon held on the outer periphery of a metallic roller body 201.
- the roller body 201 is rotatably supported on a shaft 203 (non-rotating object) via a pair of bearings 204 similarly to the pressing roller of the first embodiment.
- the outer circumference of the pressing roller 200 can be deformed into an arc following the circumference of the rope 12 even if it does not form an arc groove as in the first embodiment. Accordingly, the contact area (contact resistance) of the pressing roller 200 with the rope 12 increases, and the frictional force between the pressing roller 200 and the rope 12 can be increased (the friction resistance is large).
- the mouth body 201 itself may be a cylindrical elastic body.

- the pair of pressing rollers 3 16 presses the rope 3 12 against the outer peripheral surface of the sheave 3 11 via a belt 3 17.
- Each pressing roller 316 is rotatably supported by a shaft 318 (non-rotating object) via a pair of bearings (not shown), as in the first embodiment.
- the spring 320 presses each pressing roller 3 16 against the rope 3 12. Since each spring 3 20 can expand and contract, each pressing roller 3 16 can move with respect to the rope 3 12.
- One end of the spring 320 is supported by the fixing member 310, and the other end is connected to a circumferential groove (not shown) of the shaft 318.
- a pair of pressing rollers 3 16 always presses the rope 3 12 against the outer peripheral surface of the sheave 3 11 via a belt 3 17 by a spring 3 20.
