As a result, the movable grip portion 26 moves in the longitudinal direction of the body portion 19 in a direction approaching the fixed grip portion 24.
Next, the operation of conveying the weight 14 will be described with reference to fig. 4 and 5.
Fig. 4 and 5 are diagrams for explaining a transporting operation of a weight by the auxiliary weight transporting device for an elevator according to embodiment 1.
As shown in fig. 4, the plurality of counterweight blocks 14 are guided by a pair of grooves, not shown, formed in the counterweight frame 13. The counterweight blocks 14 are stacked in the vertical direction between the counterweight frames 13. In the uppermost counter weight 14, the counter weight transfer aid 18 is attached to either the right or left side of the center portion of the counter weight 14. At this time, the handle 23 is gripped by the operator.
Specifically, in the auxiliary weight transfer device 18, the main body 19 is disposed on the upper surface of the uppermost counter weight 14 such that the longitudinal direction thereof is perpendicular to the longitudinal direction of the uppermost counter weight 14. The fixed grip portion 24 is disposed to face one side surface of the long side of the weight 14 on the uppermost layer. The movable grip 26 is disposed to face the other side surface on the long side of the weight 14 on the uppermost layer.
At this time, the distal end portion of the fixed insertion portion 25 is disposed on the boundary line between the lower surface of the uppermost counter weight 14 and the upper surface of the counter weight 14 immediately below the lower surface from the side surface on one long side of the plurality of counter weights 14. Specifically, the distal end portion of the fixed insertion portion 25 is arranged so as to contact the boundary surface between the lower surface of the uppermost counter weight 14 and the upper surface of the counter weight 14 immediately below the lower surface from the direction perpendicular to the longitudinal direction of the uppermost counter weight.
Subsequently, the movable grip portion 26 is moved in the longitudinal direction of the body portion 19.
At this time, the distal end portion of the movable insertion portion 27 is disposed on the boundary line between the lower surface of the uppermost counter weight 14 and the upper surface of the counter weight 14 immediately below the uppermost counter weight from the side surface on the other long side of the plurality of counter weights 14. Specifically, the distal end portion of the movable insertion portion 27 is disposed so as to contact the boundary surface between the lower surface of the uppermost counter weight 14 and the upper surface of the counter weight 14 immediately below the lower surface, from the direction perpendicular to the longitudinal direction of the uppermost counter weight.
As a result, the fixed grip portion 24 and the movable grip portion 26 are arranged to sandwich the weight 14 on the uppermost layer.
Subsequently, the screw body 22 is screwed by an electric screwdriver or the like. The upper portion of the movable grip portion 26 is moved in a direction toward the weight 14 at the uppermost stage by a force of screwing the screw body 22. The movable insertion portion 27 follows the movement of the movable grip portion 26 and enters a boundary surface between the lower surface of the uppermost counter weight 14 and the upper surface of the counter weight 14 immediately below the uppermost counter weight. Meanwhile, the fixing insertion portion 25 enters a boundary surface between the lower surface of the uppermost pair of weights 14 and the upper surface of the pair of weights 14 immediately below.
As a result, a gap is formed between the pair of weights 14 on the uppermost layer and the pair of weights 14 immediately below. The load on the weight 14 at the uppermost layer is supported by the fixed insertion portion 25 and the movable insertion portion 27. At this time, when the fixed gripping portion 24 and the movable gripping portion 26 are disposed at positions in contact with the weight 14 on the uppermost layer, the loads on the weight 14 borne by the fixed insertion portion 25 and the movable insertion portion 27 are equalized.
Next, the hanging ropes 17 are attached to the pair of hook portions 21, respectively.
Next, as shown in fig. 5, the hoist rope 17 lifts the pair of weights 14 on the uppermost layer. At this time, the uppermost counter weight 14 is obliquely lifted so that one end portion side is positioned further upward. After that, the uppermost counterweight 14 is detached from the counterweight frame 13.
These steps are performed sequentially for a plurality of counterweight blocks 14. As a result, all the counterweight blocks 14 are removed from the counterweight frame 13.
According to embodiment 1 described above, the movable grip 26 is moved in the direction toward the top-most counterweight 14 by the screw 22, whereby the fixed insertion portion 25 and the movable insertion portion 27 are inserted below the counterweight 14. Therefore, the counterweight 14 of the elevator can be easily lifted.
The movable grip portion 26 moves along a notch portion provided in the body portion 19. Therefore, the movable grip 26 can be freely disposed with respect to the weight 14.
The main body 19 is provided with a handle 23. Therefore, the screw body 22 can be screwed stably.
The body 19 includes a pair of hooks 21. The lifting ropes 17 are attached to the pair of hook portions 21, respectively. Therefore, the counterweight 14 can be stably suspended.
The screw body 22 is connected to a rotation shaft of the electric screwdriver. The screw body 22 is screwed by a power screwdriver. Therefore, the operator can easily insert the movable insertion portion 27 under the counter weight 14.
The weight transfer aid 18 further includes a fixed grip buffer 24a and a movable grip buffer 26 a. The fixed grip part damper 24a and the movable grip part damper 26a grip the counterweight 14 in an elastically deformed state. Therefore, the counterweight 14 can be stably held.
The auxiliary weight transfer tool 18 can be attached near one end of the counter weight 14. Therefore, the counterweight 14 is obliquely lifted with one end side being positioned further upward. As a result, the counterweight 14 can be more easily removed from the counterweight frame 13.
The counterweight transportation assist device 18 according to embodiment 1 may be applied to an elevator in which the hoisting machine 4 is installed in the lower part of the hoistway 1, or an elevator in which the hoisting machine 4 is installed in a machine room provided directly above the hoistway 1.
