Description
Technical field
The present invention relates to the bont of tractor elevator.Specifically, relate to possess the pulley that is connected with electrical motor and rotates and solderless wrapped connection at the outer peripheral face of pulley and make the bont of elevator of the cable of lift car.
Background technology
The bont of tractor elevator in the past can be illustrated by Fig. 5.Be connected and rotate at Fig. 5 middle pulley 1 and electrical motor (not having diagram).Cable 2 solderless wrapped connections are on the outer peripheral face of pulley 1.One end of cable 2 is connected with lift car 3, and the other end then is connected with counterweight 4.
The situation that also has pulley 1 to rotate via retarder (not having diagram) from electrical motor.
During rotary driving motor, lift car 3 can be by the rotation of pulley 1 and moving up and down and lifting of cable 2.
And the rotary driving force of passing to the electrical motor of cable 2 only utilizes the friction force between the side face of the outer peripheral face of pulley 1 and cable 2 and transmits.This friction force is obtained with the tension force of counterweight 4 by the friction coefficient and the lift car 3 of pulley 1 with cable 2.
Yet, the bont of tractor elevator in the past as mentioned above, rotary driving force for the electrical motor of cable 2 is only to transmit by the outer peripheral face of pulley 1 and the friction force of cable 2, so for anti-limited slip wheel 1 with 2 of cables skid and make the rotary driving force of electrical motor can't be delivered to cable 2, and the weight of lift car 3 with counterweight 4 is increased to more than the needs.Therefore, be difficult to make the lightweight of tractor elevator device.
The present invention makes in view of above-mentioned difficult point, and its purpose is to provide a kind of bont that can realize the weight-saving elevator of tractor elevator device.
Summary of the invention
To achieve these goals, bont according to elevator of the present invention, it possesses the pulley that is connected with electrical motor and rotates and solderless wrapped connection at the outer peripheral face of pulley and order about the cable of lift car lifting, it is characterized in that having the pressure roller (give as security and pay け ロ one ラ) that cable is pressed on the outer peripheral face of pulley.That is to say, the friction force between the outer peripheral face that increases pulley by pressure roller and the side face of cable, thereby can alleviate the weight of lift car 3 and counterweight 4.Therefore can provide a kind of bont of realizing the weight-saving elevator of tractor elevator device.
In addition, the invention is characterized in that pressure roller is supported on the non-rotating thing and rotates freely, and has the pressing mechanism that pressure roller is pressed on cable.Therefore, the rotation of pressure roller becomes smooth and easy, can produce strong pressing force to cable and pulley.
In addition, the invention is characterized in that the periphery of pressure roller has the arc groove that fastens with cable.Therefore, the area of contact of pressure roller and cable hold increases, and can increase the friction force of pressure roller and cable hold.
In addition, the invention is characterized in that the periphery of pressure roller is made of elastic body.That is, the periphery of pressure roller can be deformed into circular-arc along with the circumference of cable.Therefore, the area of contact of pressure roller and cable hold increases, and can increase the friction force of pressure roller and cable hold.
In addition, the invention is characterized in, pressure roller by with respect to the rotating shaft center of pulley roughly at least one pair of of symmetry and configuration constituted.Therefore, be that one situation is compared with pressure roller, can increase the friction force between pressure roller and the cable.
In addition, the invention is characterized in that pressure roller can move with respect to above-mentioned cable.Therefore, can be corresponding to the cable of various cable diameters.
In addition, the invention is characterized in to possess the driving band of solderless wrapped connection on a pair of pressure roller, and a pair of pressure roller is pressed on the outer peripheral face of pulley by the driving band between a pair of pressure roller, with cable.Therefore, increase via the pressure roller of driving band and the area of contact of cable hold, and can increase via the pressure roller of driving band and the friction force of cable hold.

Fig. 2 is the pressure roller detailed cross sectional view partly that first embodiment of the invention relates to.
Fig. 3 is the figure of other examples of the pressure roller that the present invention relates to.
Fig. 4 is the scheme drawing of the second embodiment of the present invention.
Fig. 5 is the scheme drawing of the bont of tractor elevator in the past.
The specific embodiment
Below, with reference to accompanying drawing the first embodiment of the present invention is illustrated.In Fig. 1 and Fig. 2, the 100th, the bont of employed elevator in the tractor elevator device.Fixed parts 10 is installed in the fixed position of tractor elevator device.The rotation of electrical motor (not having diagram) is passed to the input part 111 of pulley 11 by retarder (not having diagram).That is, pulley 11 is connected with electrical motor and rotates.
Spring 20 (pressing mechanism) is pressed on each pressure roller 16 on the cable 12.Because each spring 20 can stretch, so each pressure roller 16 can move with respect to cable 12.
In addition, the fixed part of the pressing mechanism (spring 20) by can making fixed parts 10 moves with respect to fixed parts 10, and can adjust the pressing force of 16 pairs of cables 12 of each pressure roller.By the spring constant of suitable setting spring 20, and pressing force that can 16 pairs of cables 12 of each pressure roller of appropriate change.
One end fixed part 10 of spring 20 supports, and the other end is connected on the circumferential groove 21 of axle 18.Axle is to be used for the location of pair of bearings 19 and to prevent to come off with locating ring 23.
Below, the effect of the first embodiment of the present invention is described.
A pair of pressure roller 16 is pressed on cable 12 outer peripheral face of pulley 1 always by spring 20.That is, increase friction force between the side face of the outer peripheral face of pulleys 1 and cable 12 by a pair of pressure roller 16.Thereby, can alleviate the weight of lift car 3 and counterweight 4.
(another example of pressure roller)
The example of the other a pair of pressure roller that the present invention relates to reference to accompanying drawing explanation.In Fig. 3, elastic bodys 202 cylindraceous such as the rubber of each pressure roller 200 or silicone are maintained at the periphery of rigid roller main body 201.Pressure roller among roller main body 201 and above-mentioned first embodiment in the same manner, by pair of bearings 204 be supported on that axle 203 (non-rotating things) are gone up and rotation freely.
Even the periphery of pressure roller 200 does not form the arc groove shown in above-mentioned first embodiment, also can be deformed into circular-arc along with the circumference of cable 12.Therefore, the area of contact (contact resistance) of 200 pairs of cables 12 of pressure roller increases, and can increase the friction force (friction drag is big) of 12 of pressure roller 200 and cables.
Even elastic body 202 is not installed in addition and is made roller main body 201 own passable yet as elastic body cylindraceous in the periphery of pressure roller 200.
