The sprockets 23 transmit rotation to the plurality of rollers 24, respectively. The pair of handrails 12 are cyclically moved by frictional force between the rollers 24 in contact with each other by receiving pressure from each of the rollers 25 in contact with each other. The pair of handrails 12 are cyclically moved at the same moving speed as the respective moving speeds of the plurality of steps 11.
During an upward operation of the passenger conveyor 1, which is an escalator, a user grips one of the pair of handrails 12 and gets on any one of the steps 11 from the 2 nd entry/exit 2 b. The user gets on the step 11 moving on the forward path and moves to the 1 st landing entrance 2 a.
Next, an outline of the method of pulling out the drive pulley 15 will be described with reference to fig. 2.
Fig. 2 is a plan view of an upper machine room of a passenger conveyor to which a pull-out assist of a rotating body of an elevator in embodiment 1 is applied.
As shown in fig. 2, the drive pulley 15 is adjacent to a structure such as the main frame 3 on one side in the upper machine room 14 a. In this state, the operator inserts the auxiliary pulling-out tool 26 into the drive pulley 15 from above the drive pulley 15. Then, the operator operates the pullout aid 26 to pull out the drive pulley 15 from the distal end portion of the rotation shaft of the drive device 4 toward the structure body side such as the main frame 3.
Next, the pullout aid 26 will be described with reference to fig. 3 and 4.
Fig. 3 is a front view of a pulling-out aid of a rotating body of an elevator in embodiment 1. Fig. 4 is a plan view of the auxiliary tool for pulling out the rotating body of the elevator according to embodiment 1.
As shown in fig. 3 and 4, the auxiliary extraction tool 26 includes a main body 27, a screw body 28, a pair of side claws 29, a pair of movement inhibitors 30, and an upper claw 31.
For example, the main body 27 is formed of a metal in a square tube shape. The main body 27 is arranged to straddle the surface of the drive pulley from one side to the other side on the distal end side of the rotary shaft of the drive device.
For example, the screw-in body 28 is a ball stud. The screw body 28 is screwed into the center of the main body 27. When the main body 27 is disposed so as to extend from one side to the other side of the surface of the drive pulley 15, the screw body 28 faces the distal end portion of the rotation shaft of the drive device 4.
For example, the pair of side claws 29 are each formed of L-shaped metal. The pair of side claws 29 has an upper adjustment knob 29a and a lower adjustment knob 29b, respectively.
One of the pair of lateral claws 29 has a base portion penetrating one side of the main body 27. One of the pair of lateral claws 29 is coupled to one side of the main body 27 by an upper adjustment knob 29a and a lower adjustment knob 29b so as to be movable in a direction approaching the screw-in body 28 and in a direction separating from the screw-in body 28. When the main body 27 is disposed so as to straddle the drive pulley 15 from one side of the front surface to the other side thereof, one of the pair of side pawls 29 is disposed so as to extend from the outer side of the one side of the drive pulley 15 to the rear surface of the drive pulley 15.
The base of the other of the pair of lateral claws 29 penetrates one side of the main body 27. The other of the pair of side claws 29 is coupled to the other side of the main body 27 by an upper adjustment knob 29a and a lower adjustment knob 29b so as to be movable in a direction approaching the screw-in body 28 and a direction separating from the screw-in body 28. When the main body 27 is disposed so as to straddle the drive pulley 15 from one side of the front surface to the other side thereof, the other of the pair of lateral pawls 29 is disposed so as to go around from the outside of the other side of the drive pulley 15 to the other side of the rear surface of the drive pulley 15.
For example, one of the pair of movement inhibitors 30 is a round head embedded screw. One of the pair of movement suppressing members 30 is screwed into the upper surface of the main body 27 at a position closer to the main body 27 than one of the pair of lateral claws 29 on the upper surface of the main body 27. One of the pair of movement restraining bodies 30 restrains one of the pair of side claws 29 from coming off from one side of the main body 27.
For example, the other of the pair of movement inhibitors 30 is a round head embedded screw. The other of the pair of movement suppressing members 30 is screwed into the upper surface of the main body 27 at a position on the other side of the main body 27 than the other of the pair of lateral claws 29 on the upper surface of the main body 27. The other of the pair of movement restraining bodies 30 restrains the other of the pair of lateral claws 29 from coming off from the side of the main body 27.
For example, the upper claw 31 has a lower angle iron 31a, an upper angle iron 31b, and an adjusting screw 31 c. For example, the lower angle iron 31a is formed of metal. For example, the upper side angle iron 31b is formed of metal. The lower angle iron 31a and the upper angle iron 31b are fastened by an adjusting screw 31 c.
The upper claw 31 is coupled to the center of the main body 27 so as to be movable in a direction approaching the screw body 28 and in a direction separating from the screw body 28 by changing the fastening position of the adjusting screw 31c to the lower angle 31a and the upper angle 31b in the vertical direction. The upper claws 31 are arranged such that the lower surfaces of the upper portions of the upper angle bars 31b contact the upper side of the outer peripheral surface of the drive pulley when the main body 27 is arranged so as to straddle the drive pulley 15 from one side to the other side of the surface. At this time, the distal end portion of the upper angle 31b is arranged to extend from the upper outer side of the drive pulley 15 to the upper side of the rear surface of the drive pulley 15.
When the extraction aid 26 is fitted to the drive pulley 15 from above the drive pulley 15, the screw body 28 faces the distal end portion of the rotation shaft of the drive device 4. In this state, when the screw body 28 is screwed by a wrench or the like, the screw body 28 comes into contact with the tip end portion of the shaft of the driving device 4. In this state, when the screw body 28 is further screwed in by a wrench or the like, the pair of side claws 29 and the upper claw 31 contact the back surface of the drive pulley 15. In this state, when the screw body 28 is further screwed in by a wrench or the like, the pair of side claws 29 and the upper claw 31 move the drive pulley 15 in a direction of being pulled out from the distal end portion of the rotation shaft of the drive device 4.
Next, the adjustment of the pullout aid 26 will be described with reference to fig. 5.
Fig. 5 is a front view of the elevator according to embodiment 1 when adjusting the auxiliary device for pulling out the rotating body.
As shown in fig. 5, the pullout aid 26 is adjusted according to the outer diameter of the pulley.
For example, when the drive pulley 15 is pulled out, the distance between the facing surfaces of the pair of side pawls 29 is set to be slightly longer than the outer diameter of the drive pulley 15. In the upper claw 31, the lower surface of the upper portion of the upper angle 31b is set so that the tip end portion of the screw body 28 faces the rotation shaft of the drive device 4 when contacting the upper side of the outer peripheral surface of the drive pulley 15.
For example, when the driven pulley 16a is pulled out, the distance between the facing surfaces of the pair of side claws 29 is set to be slightly longer than the outer diameter of the driven pulley 16 a. In the upper claw 31, the lower surface of the upper portion of the upper angle 31b is set so that the tip end portion of the screw body 28 faces the rotation shaft of the reduction gear 5 when contacting the upper side of the outer peripheral surface of the driven pulley 16 a.
According to embodiment 1 described above, the upper claws 31 are arranged such that the lower surfaces of the upper portions of the upper angle irons 31b contact the upper side of the outer peripheral surface of the pulley when the main body 27 is arranged so as to straddle the pulley from one side to the other side of the surface. Therefore, even if the hand of the operator is separated from the removal aid 26, the rotation shaft of the pulley and the screw body 28 can be easily opposed to each other. As a result, even when the working space is narrow, the pulley can be easily pulled out from the rotating shaft.
At this time, when the pulley is pulled out, the pull-out aid 26 is fitted to the pulley from above. Therefore, even when the working space is narrow, the auxiliary extraction tool 26 can be easily installed.
Further, when the main body 27 is disposed so as to straddle from one side to the other side of the surface of the pulley, the distal end portion of the upper claw 31 winds from the outside of the upper side of the pulley to the upper side of the rear surface of the pulley. Therefore, the pulley can be easily pulled out from the rotating shaft in a stable state by the pair of side claws 29 and the upper claw 31.
The pair of side claws 29 are coupled to the main body 27 so as to be movable in a direction approaching the screw-in body 28 and in a direction separating from the screw-in body 28. Upper claw 31 is coupled to main body 27 so as to be movable in a direction approaching to and a direction separating from screw-in body 28. Therefore, pulleys having different outer diameters can be extracted using 1 extraction aid 26.
The pullout aid 26 according to embodiment 1 may be applied to a rotating body other than a pulley. For example, the pullout aid of embodiment 1 can be applied to a sprocket.
The auxiliary pulling-out tool 26 according to embodiment 1 may be used for a rotating body of an elevator other than an escalator. For example, the pullout aid of embodiment 1 can be used for a drive pulley or a driven pulley of a moving walkway. For example, the extraction aid of embodiment 1 may be used for a pulley that is a sheave of a hoisting machine of an elevator.
