Note that FIGS. 12 to 15 are views of the climbing device 1 viewed from the front side).

  Next, the guard plate 42 is rotated counterclockwise in FIG. 12, and the push button 43 is passed from one end side to the back side of the bulging portion 45 (see arrow G in FIG. 12, arrow H in FIG. 13). ) While pushing the push button 43 slightly in the middle, it is exposed to the engagement hole 44 from the end edge 48 on the other end side. The push button 43 returns to the original return state, and fixes the guard plate 42 at a position where the opening 30 is closed (see FIG. 14). The lower side 112b of the hanging rope 112 hangs downward from the climbing device 1.

The climbing device 5 is also configured in exactly the same way as the climbing device 1, and can be attached to the hanging rope 113 by the same method as described in the climbing device 1.
The carabiner 2 is removably attached to the carabiner hooking hole 40 of the support shaft 41 of the climbing device 1, and hooks (not shown) on one end side of the wire ropes 3 and 4 are suspended on the carabiner 2, and the wire rope The hooks (not shown) on the other end side of 3 and 4 are hooked to the rope attachment plates 145 and 146 fixed to the upper left end portion of the device main body 121 of the hanging type curing device 120 (see FIG. 2). Similarly, the carabiner 6 is removably attached to the carabiner hooking hole 40 of the support shaft 41 of the climbing device 5, and hooks (not shown) on one end side of the wire ropes 3 and 4 are suspended from the carabiner 6. By hooking hooks (not shown) on the other end side of the wire ropes 7 and 8 to rope attachment plates 147 and 148 fixed to the upper right end portion of the apparatus main body 121 of the hanging type curing device 120 (see FIG. 2). ), The hanging type curing device 120 can be lifted and lowered using a pair of climbing devices 1 and 5.
The carabiners 2 and 6 are vertically long, and when the guard plate 42 is opened for the operation of the operation member 54, the guard plate 42 is greatly rotated while passing through the gaps inside the carabiners 2 and 6, The finger can be hooked on the finger hook 59 of the operation member 54.

  When the load of the suspension type curing device 120 is applied to the climbing devices 1 and 5 via the ropes 3 and 4, 7 and 8 (floating from the ground), the upper side 112 a of the hanging rope 112 and the upper side 113 a of the 113 14 is generated in the pulley 16 in the clockwise direction in FIG. 14. At this time, a rotational force in the direction of approaching the pulley 16 is generated in the cam 50, and the rope contact portion 51 bites into the rope 2 and is pinched. At the same time, the teeth 52 are stuck in the rope surface and the rotation of the pulley 16 is restricted. For this reason, the ascending / descending apparatuses 1 and 5 do not descend with respect to the hanging ropes 112 and 113.

  When it is desired to raise the suspension type curing device 120, the worker A on the left side fits and fastens the input shaft 17 of the climbing device 1 to the chuck 151 as the output shaft of the electric driver 150 carried by himself / herself (FIG. 5). Reference), the electric driver 150 is rotated clockwise in FIG. Then, the rotational force of the electric driver 150 is decelerated by the transmission mechanism 20 and the pulley 16 rotates counterclockwise in FIG. 15, and the suspension rope 112 is moved counterclockwise along the circumferential direction of the pulley 16. At this time, since the cam 50 receives a force in a direction away from the pulley 16, the pulley 16 is not restrained from rotating, and the suspension rope 112 is continuously moved in the counterclockwise direction (the climbing direction of the climbing device 1).

In parallel with the worker A, the worker B on the right side fits and fastens the input shaft 17 of the climbing device 5 to the chuck 151 as the output shaft of the electric driver 150 carried by himself (see FIG. 5). By rotating the driver 150 clockwise in FIG. 15, the hanging rope 113 can be continuously moved in the counterclockwise direction (the climbing direction of the climbing device 5).
Thereby, the workers A and B can raise the suspension type curing device 120 along the suspension ropes 112 and 113 while keeping the suspension type curing device 120 substantially horizontal. If the electric driver 150 is stopped at a desired height position, the rise can be stopped. At this time, tension is applied to the upper side 112a of the suspension rope 112 and the upper side 113a of the suspension rope 112 by the load of the suspension type curing device 120, and a clockwise rotational force is generated in the pulley 16, but the rope contact portion 51 of the cam 50 is The rotation of the pulley 16 is constrained by clamping. For this reason, the ascending / descending apparatuses 1 and 5 do not descend with respect to the hanging ropes 112 and 113.
The workers A and B may alternately lift the climbing devices 1 and 5 by the electric driver 150.

  On the other hand, when the suspension type curing device 120 is to be lowered, the worker A on the left presses the push button 43 of the climbing device 1 to open the guard plate 42 widely, and puts his thumb on the finger rest 59 of the operation member 54. 3 is rotated clockwise or pulled away from the pulley 16 to loosen the holding pressure of the suspension rope 112 by the cam 50, and the pulley 16 is moved by the weight of the suspension type curing device 120. 3, the ascending / descending apparatus 1 is lowered with respect to the hanging rope 112 while rotating clockwise.

In parallel, the operator B pushes the push button 43 of the ascending / descending apparatus 5 to open the guard plate 42 widely, puts his thumb on the finger-hooking portion 59 of the operation member 54, rotates in the clockwise direction in FIG. The lifting device 5 is moved relative to the hanging rope 113 while the pulley 16 is rotated in the clockwise direction in FIG. 3 by the weight of the hanging type curing device 120 by loosening the holding pressure of the hanging rope 113 by the cam 50. Descent.
Thereby, the workers A and B can be lowered along the suspension ropes 112 and 113 while keeping the suspension type curing device 120 substantially horizontal. If the operation member 54 is released at a desired height and the suspension ropes 112 and 113 are clamped by the cam 50, the descent can be stopped.
In addition, the workers A and B may lower the climbing devices 1 and 5 alternately.

Next, a working method for the outer surface of the building 1 will be described with reference to FIG.
In advance, two support tools 110 and 111 are attached to the parapet 103 on the roof of the building 100 at the same interval as the width of the suspension type curing device 120, and the suspension ropes 112 and 113 suspended from the respective end portions. The safety ropes 101 and 102 on the main side and the backup side for the worker A, and the safety ropes 104 and 105 on the main side and the backup side for the worker B are parapets. It is assumed that it is overhanging 103 and hangs near the ground.

Further, the climbing device 5 is attached to the hanging rope 113, and the other ends of the ropes 6 and 7 suspended from the carabiner 6 hung in the hole 40 of the climbing device 5 are hooked to the rope mounting plates 147 and 148. To wear. At this time, the suspension type curing device 120 floats about several tens of cm to 1 m from the ground so that the load is applied to the climbing devices 1 and 5. The lower sides 112 a and 113 a of the hanging ropes 112 and 113 are allowed to hang inside the apparatus main body 121.

  Next, on the roof of the building 100, the lanyard on the main side of the safety belt attached to the worker A is hooked on a lifting device (not shown) attached to the safety rope 101, and the lanyard on the backup side is secured. Hang on a fall prevention device (not shown) attached to the rope 102 and pass through the parapet 103 and hang on the safety rope 101 along the outer surface of the building 100 to the inside or just above the hanging type curing device 120 Descend. In parallel with worker A, worker B also attaches the lanyard on the main side of the safety belt attached to himself / her to a lifting device (not shown) attached to safety rope 104, and uses the safety lanyard on the backup side as the safety rope. Hang on a fall prevention device (not shown) attached to 105 and descend to the inside of the hanging type curing device 120 or just above the parapet 103 while hanging on the safety rope 101 along the outer surface of the building 100. To do.

  Workers A and B make sure that no weight is applied to the hanging type curing device 120, and the lower sides of the safety ropes 101, 102, 104, and 105 are suspended in the device main body 121, and both hands are dropped. Work such as inspection and repair on the outer surface of the building 100 is performed at a position on the prevention plate 125 at the building side opening of the enclosure curing unit 122. A repairing device or a debris such as a wall generated by the operation hits the enclosure curing unit 122 or the fall prevention plate 125 and falls to the apparatus main body 121 or directly falls into the apparatus main body 121 to be suspended. The falling and scattering of 120 to the outside are prevented. Further, even when the work tool is accidentally dropped, it falls on the floor 152 of the apparatus main body 121, so that it is prevented from dropping to the ground.

When it is desired to move the building 100 to the upper working range at the time of the current work, the workers A and B slightly move the positions of the lifting and falling devices attached to the safety ropes 101 and 102, 104 and 105 upward. While moving and climbing, the climbing devices 1 and 5 are slightly driven in the climbing direction by the electric driver 150 carried by each, and the suspension type curing device 120 is slightly lifted along the suspension ropes 112 and 113 to move up one level. (Both hands are placed on the fall prevention plate 125 at the height position of the building-side opening of the curing unit 122). Before and after the movement and during the movement, the workers A and B make sure that the weight is not applied to the suspension type curing device 120 at all. When the rising height is insufficient, the climbing height of the workers A and B and the lifting of the hanging type curing device 120 are repeated several times. Then, a repair work or the like is performed on the outer surface of the building 100 slightly above the previous work.

The exit side ropes 112 b and 113 b of the suspension ropes 112 and 113 are allowed to hang down in the apparatus main body 121 of the suspension type curing apparatus 120.
When the suspension type curing device 120 is lifted about several tens of centimeters to 1 m from the ground so that the load is applied to the left and right rope pulling devices 501, the entrance side ropes 112a and 113a of the suspension ropes 112 and 113 are moved upward from the entrance portion 532. The pulley 520 tries to rotate in the reverse direction by applying a force in the direction of pulling outward, but the tip of the pawl 564 of the ratchet mechanism 560 engages with the ratchet gear 562 to limit the rotation of the input shaft 507. 520 does not rotate, the entrance side ropes 112a and 113a of the suspension ropes 112 and 113 are pulled out, and the rope pulling device 501 and the suspension type curing device 120 are prevented from descending.

  To start work on the exterior of the building, on the roof of the building 100, the worker A attaches the lanyard on the main side of the safety belt attached to himself / her to the lifting / lowering device (not shown) attached to the safety rope 101 and backs up. The lanyard on the side is attached to a fall prevention device (not shown) attached to the safety rope 102, and is suspended from the safety rope 101 along the outer surface of the building 100 across the parapet 103 while Descent to the middle or just above. In parallel with worker A, worker B also attaches the lanyard on the main side of the safety belt attached to himself / her to a lifting device (not shown) attached to safety rope 104, and uses the safety lanyard on the backup side as the safety rope. Hang on a fall prevention device (not shown) attached to 105 and descend to the inside of the hanging type curing device 120 or just above the parapet 103 while hanging on the safety rope 101 along the outer surface of the building 100. To do.

Workers A and B make sure that no weight is applied to the hanging type curing device 120, and the lower sides of the safety ropes 101, 102, 104, and 105 are suspended in the device main body 121, and both hands are dropped. Work such as inspection / repair on the outer surface of the building 100 is performed at a position on the prevention plate 125 at the building-side opening of the enclosure curing unit 122.
When moving to the work range one level higher than that at the time of the current work with respect to the building 100, the workers A and B slightly raise the positions of the lifting and falling devices and the fall prevention devices attached to the safety ropes 101 and 102, 104 and 105. Move and climb. Then, the workers A and B drive the forward rotation of the input shaft 507 of the left and right rope traction devices 501 by the rechargeable electric driver 515 carried by each, and the suspension type curing device 120 is suspended along the suspension ropes 112 and 113. Slightly raise and move to the work area one level above (both hands are placed on the fall prevention plate 125 so that they are at the height of the building-side opening of the curing unit 122).

Specifically, the worker A (B) removes the exit side rope 112b (113b) of the hanging rope 112 (113) loaded in the rope pulling device 501 from the latching portions 580 and 581, and the operation knob 571 is the first. The position P1 remains fixed. As shown in FIG. 28 (1), a cylindrical shank 518 with a keyway 517 is attached to a chuck 516 of a rechargeable electric driver 515, and the key 519 is attached to the keyways 514 and 517 of the input shaft 507 of the rope traction device 501. The shank 518 is inserted and connected to the shaft hole 513 while being fitted, and the rechargeable electric driver 515 is driven in the forward rotation direction.
In the rope traction device 501, the ratchet mechanism 560 allows the input shaft 507 to rotate forward, so the input shaft 507 rotates forward, is decelerated by the speed reducer body 506, is transmitted to the output shaft 508, and is coupled to the output shaft 508. The pulley 520 thus rotated rotates counterclockwise in FIG. As a result, the inlet side of the suspension rope 112 (113) is drawn into the upper left portion of the pulley 520 through the left side of the inlet passage portion 534 and the separation portion 540, and slightly turns around the right side of the separation portion 540 from the upper right portion of the pulley 520. And exits through the exit passage portion 535. As a result, the suspension type curing device 120 rises from near the ground.

  When the desired height is reached, the driving of the rope traction device 501 by the rechargeable electric driver 515 is stopped. Then, the entrance side rope 112a (113a) of the suspension rope 112 (113) is pulled upward as viewed from the rope traction device 501 by the load of the suspension type curing device 120, but the ratchet mechanism 560 rotates the input shaft 507 in the reverse direction. Since the reverse rotation of the pulley 520 is restricted and the suspension rope 112 (113) is prevented from being pulled out from the entrance side of the rope traction device 501 in the outward direction. Therefore, the suspension type curing device 120 is stopped at a desired height.

It should be noted that the workers A and B do not apply any weight to the hanging type curing device 120 before or after the movement or during the movement. When the rising height is insufficient, the climbing height of the workers A and B and the lifting of the hanging type curing device 120 are repeated several times. Then, a repair work or the like is performed on the outer surface of the building 100 slightly above the previous work.
Hereinafter, in the same manner, while repeating the work such as repairing the outer surface of the building 100 surrounded by the suspension type curing device 120, the height of the workers A and B and the lifting of the suspension type curing device 120. The work such as repair on the outer surface of the building 100 is performed from the ground side to the rooftop.

If it is desired to change the work position slightly below the building 100 on the way, the workers A and B slightly move the positions of the lifting and falling devices attached to the safety ropes 101 and 102, 104 and 105 downward. To descend to the desired height position. Then, each of the workers A and B releases the restriction of the ratchet mechanism 60 of the left and right rope traction devices 501, and along the suspension ropes 112 and 113 by the own weight of the suspension type curing device 120 while reversing the pulley 520. Lower it a little.
Specifically, the exit side rope 112b (113b) of the hanging rope 112 (113) is first wound around the latching portions 580 and 581 and fixed so as not to be pulled back to the pulley side. Next, in order to release the rotation restriction by the ratchet mechanism 560 of the rope traction device 501, the operation knob 571 is turned to the second position P <b> 2 to engage the engagement protrusion 574 with the engagement recess 576 and fix it. The rope traction device 501 and the suspension-type curing device 501 load the rope 520 so that the entrance-side rope 112a (113a) pulled strongly upward as viewed from the rope traction device 501 urges the pulley 520 clockwise. The gear 562 strongly presses the tip of the pawl 564, and the pawl 564 is difficult to rotate.

  Therefore, as shown in FIG. 29 (1), the rotary shaft portion 592 is inserted into the shaft hole 513 while fitting the protrusion 591 of the manual rotary tool 590 into the key groove 514 of the input shaft 507. Then, while rotating the handle portion 593 in the counterclockwise direction (forward rotation direction) of FIG. 29A to loosen the pressure of the ratchet gear 562 against the pawl 564, the operation knob 571 is rotated to the second position P2 to engage the protrusion. 574 is engaged with the engagement recess 576 and fixed. Thereby, the pawl 564 is separated from the ratchet gear 562, and the rotation restriction of the input shaft 507 is released.

In this state, when the outlet side rope 112b (113b) is grasped by hand and removed from the latching portions 580 and 581 of the rope traction device 501, the inlet side rope 112a is reduced when the gripping force of the outlet side rope 112b (113b) is weakened. The pulley 520 rotates in the clockwise direction in FIG. 30 by the pulling force of (113a), and the outlet side rope 112b (113b) is pulled back to the inlet side. At this time, since the differential speed reduction mechanism of the speed reducer main body 506 becomes a large load, the suspension rope 112 (113) is slowly pulled out from the inlet portion 532, and the suspension type curing device 120 is slowly lowered. If the exit-side rope 112b (113b) of the suspension rope 112 (113) is pressed against the latching portions 580 and 581, it can be lowered more slowly by applying a friction brake.
When the height is lowered to the desired height, the outlet side rope 112b (113b) is hooked on the hooking portions 580 and 581 and the operation knob 571 is changed to the first position P1. When the descending height is insufficient, the descending of the workers A and B and the descending of the hanging type curing device 120 may be repeated several times. Then, work such as repair is performed on the outer side of the building 100 slightly below the previous work.
First, if the suspension type curing device 120 is raised to near the rooftop, the repair work for the outer surface of the building 100, the lowering of the workers A and B, and the lowering of the suspension type curing device 120 are repeated. However, it is also possible to perform work such as repair on the outer surface of the building 100 from the roof side.

According to the rope traction device 501 shown in FIG. 16, the suspension ropes 112 and 113 can be pulled by using the rotary electric tool as a drive source, and the suspension type curing device 120 can be raised and lowered. There is no need to incorporate it, and since it is wound around the pulley 520 and pulled, no take-up drum is required, and the apparatus can be made compact as a whole. In addition, a normal tool carried for work such as an electric driver 515 can be used as the rotary electric tool, and there is no need to prepare a special drive source. If the rotary electric tool is rechargeable, there is no need to bother the power cord.
Further, by using the differential reduction type reduction gear main body 506 that is small and has a large reduction ratio, the suspension ropes 112 and 113 are moved outward from the inlet portion 532 while the pulley 520 is reversed with the restriction means 510 released. When the suspension type curing device 120 is pulled out and lowered, a slowing operation can be performed.
In addition, the rope entrance / exit part 531 is composed of an entrance part 532 and an exit part 533 that are arranged to face each other with a gap, and a rope suspended between the outside and the entrance part 532 through a gap 544 between the entrance part 532 and the exit part 533. 112 and 113 can be taken in and out, and the suspension ropes 112 and 113 can be inserted and removed between the outside and the outlet portion 533, so that the suspension ropes 112 and 113 can be easily loaded into and removed from the pulley 520.
In addition, the rope entrance / exit part 531 is provided at a distance from the pulley 520, and the separation part 540 for separating the entrance side ropes 112a, 113a and the exit side ropes 112b, 113b is provided between the rope entrance / exit part 531 and the pulley 520. Further, it is possible to prevent the outlet side ropes 112b and 113b from being wound around the inlet side of the pulley 520 during the forward rotation of the pulley 520, and the inlet side ropes 112a and 113a from being caught into the outlet side of the pulley 520 when the pulley 520 is rotated in reverse.
In addition, since the suspension members 580 and 581 are provided on the support body 502 so that the suspension ropes 112 and 113 are wound and stopped, the restriction by the restriction means 510 is performed while tension is applied to the entrance side of the suspension ropes 112 and 113. , And when the suspension type curing device 120 is to be lowered by moving the entrance side ropes 112a and 113a upward and outward from the entrance part 532, the exit side ropes 112b and 113b are previously attached to the latching parts 580 and 581. By winding and retaining, it is possible to prevent the inlet side ropes 112a and 113a from being suddenly pulled out upward and outward from the inlet portion 532 when the restricting means 510 is released. In addition, the friction brake can be applied by moving the latching portions 580 and 581 while making sliding contact.
Further, when it is desired to cancel the restriction of the rope movement from the inlet 532 to the upper outside by the restricting means 510, the input shaft 507 of the speed reducer main body 506 is manually rotated forward by using the manual rotary tool 590 so that the pulley 520 is moved. It can be easily released by performing a release operation with the operation knob 571 while slowly rotating forward.

In the rope traction device shown in FIG. 16, the rechargeable electric driver is cited as the rotary electric tool. However, the present invention is not limited to this, and other rotary electric tools such as an electric drill may be used. . Moreover, you may use the electric tool which is not rechargeable.
In the rope traction device shown in FIG. 16, there is a gap between the inlet portion and the outlet portion after the hanging rope is loaded. However, as shown in the rope traction device 501A in FIGS. The fitting portion of 550A is extended upward so that it can be fitted to the upper ends of the inlet portion 532A and the outlet portion 533A, and between the inlet portion 532A and the outlet portion 533A on the back side of the upper extension portion of the pulley cover 550A. The gap 544A is blocked and the entrance-side rope inserted into the entrance passage 534 of the entrance 532A is prevented from shifting to the gap 544A, or the exit-side rope inserted into the exit passage 535 of the exit 533A is directed to the gap 544A. You may project the baffle part 586 which disturbs shifting. When the rope traction device 501A is in use, the hindering portion 586 causes the suspension rope to be shifted to the gap 544A between the inlet portion 532A and the outlet portion 533A, and collides with the rear surface of the upper end portion of the pulley cover 550A to be inadvertently opened. Can be prevented.
In the rope traction device shown in FIG. 16, the pawl is urged in the direction of the ratchet gear by the compression coil spring, but may be urged by a plate spring, a torsion spring, or the like. Moreover, although the case where the limiting means for restricting the loaded suspension rope from being pulled back from the inlet side is provided on the input shaft side of the differential speed reducer main body has been described as an example, it should be provided on the output shaft side. Also good.

  Further, the restricting means replaces the ratchet mechanism, and when the suspension rope tries to move in a direction to be pulled out from the entrance portion, the restriction means bites into the suspension rope and restricts the movement, and when trying to move in the opposite direction, Cam configured to allow movement away from the suspension rope, biasing means for biasing the cam in the direction of biting the suspension rope, and release for releasing the restriction by separating the cam from the suspension rope It is good also as a structure containing a means.

  One specific example of the cam-type limiting means is shown in FIG. In the rope traction device 501B of FIG. 340, the upper portion of the support body 502B extends upward, and a cam-type limiting means 600 is mounted on the front side. Of the restricting means 600, reference numeral 601 denotes a support plate mounted on the front side of the upper end portion of the support body 502B, and the left side portion is bent into a U shape to form a rope insertion portion 602 as a rope contact portion on the inside. The bent portion 603 is formed into a bent portion 605 in which the right side portion is bent in a U shape and the rotating shaft 604 is rotatably mounted. The rope insertion part 602 is arranged along the path on the inlet side of the suspension rope loaded in the rope pulling device 501B, and is arranged linearly with respect to the inlet passage part 534 of the inlet part 532. The rotation shaft 604 is fitted with a base end portion of a cam 608 having a large number of teeth 607 protruding from an outer peripheral portion 606. The cam 608 approaches the suspension rope inserted through the rope insertion part 602 with the rotation shaft 604 as the center of rotation (see arrow i in FIG. 33) and moves away (see arrow j in FIG. 33). It can be turned. A mainspring spring (not shown) that constantly biases the cam 608 clockwise in FIG. 33 is interposed between the rotation shaft 604 and the cam 608.

  A rotating shaft 609 is rotatably mounted near the center of the cam 608, and a base end portion of an L-shaped release operation member 610 is fitted to the rotating shaft 609. A columnar operation protrusion 611 that protrudes forward of the support 602B is attached to a corner portion of the release operation member 610, and the release operation member 610 centering on the rotation shaft 609 by operating the operation protrusion 611 with a finger. Is freely rotatable (see arrows k and l in FIG. 33). The distal end side of the release operation member 610 is bent into a J shape, and is an engaging portion 612 that is detachably engaged with the outside of the bent portion 605 of the support plate 601. A mainspring spring (not shown) that constantly biases the release operation member 610 in the counterclockwise direction of FIG. 33 is interposed between the rotation shaft 609 and the release operation member 610.

  The method of loading the hanging rope onto the rope traction device 501B of FIG. 33 will be described. First, the operation protrusion 611 of the limiting means 600 is operated with a finger, and the cam 608 and the release operation member 610 are rotated in parallel. 34, the engaging portion 612 is engaged with the outside of the bent portion 605. The pulley cover 550 is opened and one end of the suspension rope 112 (113) is inserted into the rope insertion portion 602 of the restricting means 600, and further inserted into the inlet passage portion 534 through the gap 544 between the inlet portion 532 and the outlet portion 533. Then, the pulley 520 is slightly wound around the pulley 520 through the left side of the separating portion 540, and inserted into the outlet passage portion 535 through the right side of the separating portion 540 through the gap 544 between the inlet portion 532 and the outlet portion 533 (see FIG. 34), and then the latching portion 580. , Wrap around 581 and hang.

  Then, the pulley cover 550 is closed, and the operation protrusion 611 of the release operation member 610 is operated with a finger to disengage the engagement portion 612, and the cam 608 and the release operation member 610 are rotated in parallel. Then, the cam 608 is brought close to the hanging rope 112 (113) and the finger is released. The cam 608 is urged in the direction of the rope in which the outer peripheral portion 606 is inserted into the rope insertion portion 602 by the spring, and presses against the hanging rope 112 (113). When the suspension rope 112 (113) is pulled downward (see arrow r in FIG. 35) on the exit side of the rope insertion portion 602, an external force in the counterclockwise direction is applied to the cam 608, but the outer peripheral portion 606 is a suspension rope. Since the cam 608 is easily rotated counterclockwise because the direction is away from 112 (113), movement of the inlet side rope 112a (113a) in the pulley direction is allowed. Conversely, when the hanging rope 112 (113) is pulled upward (see arrow s in FIG. 35) on the entrance side of the rope insertion portion 602, an external force in the clockwise direction is applied to the cam 608, but the outer peripheral portion 606 is suspended. Since the cam 608 is in the direction approaching the lowering rope 112 (113), the cam 608 bites into the lowering rope 112 (113) and restricts the movement (the lowering rope 112 (113) is sandwiched between the rope insertion part 602 and the cam 608).

In order to start pulling the suspension rope 112 (113) in order to raise the suspension type curing device 120, the exit side rope 112b (113b) is removed from the winding portions 580 and 581, and the rechargeable electric driver 515 inputs the input shaft. 507 is rotated forward. Then, since the pulley 520 rotates in the forward direction, and the restricting means 600 allows the suspension rope 112 (113) to move at this time, the entrance side rope 112a (113a) is smoothly pulled by the pulley 520, and the suspension rope The rope traction device 501 </ b> B and the suspension type curing device 120 rise along the lines 112 and 113.
When it is desired to stop towing the hanging rope 112 (113), the driving of the input shaft 507 by the rechargeable electric driver 515 is stopped. When the suspension rope 112 (113) is pulled upward as viewed from the rope traction device 501B on the entrance side of the rope insertion portion 602 by the weight of the suspension type curing device 120 and the rope traction device 501B, an external force in the clockwise direction is applied to the cam 608. However, since the outer peripheral portion 606 is in a direction approaching the hanging rope 112 (113), the cam 608 bites into the hanging rope 112 (113) and restricts movement. Therefore, the exit side rope 112b (113b) is not pulled back to the entrance side, and the rope traction device 501B and the suspension type curing device 120 are not lowered.
In response to the weight of the rope pulling device 501B and the suspension type curing device 120, the entrance side rope 112a (113a) is pulled upward in FIG. 35 as viewed from the rope pulling device 501B and pulled back in the pulling direction. When the rope pulling device 501B and the suspension type curing device 120 are to be lowered, the exit side rope 112b (113b) is wrapped around the latching portions 580 and 581 and latched, and the manual rotary tool 590 is attached to the input shaft 507. Coupling and rotating forward, the cam 608 bites into the hanging rope 112 (113) is loosened, the operation projection 611 of the limiting means 600 is operated with a finger, and the cam 608 and the release operation member 610 rotate in parallel. Then, the engaging portion 612 is engaged with the outside of the bent portion 605 as shown in FIG. When the gripping force for gripping the outlet side rope 112b (113b) removed from the latching portions 580 and 581 is weakened, the pulley 520 is reversed by the pulling force of the inlet side rope 112a (113a), and the outlet side rope 112b (113b). ) Is pulled back to the entrance side, and the rope pulling device 501B and the hanging type curing device 120 are lowered by the hanging rope 112 (113).

  33, without using the ratchet mechanism, the rope traction device 501B is lowered by pulling back the exit side rope 112b (113b) while the suspension rope 112 (113) is being pulled up or stopped. In addition, it is also possible to release the restriction when it is desired to pull out and lower the entrance side of the hanging rope 112 (113). Further, since the rope insertion portion 602 of the restricting means 600 is disposed on the inlet side of the support body 502B from the inlet portion 532, the rope passage on the inlet side becomes longer, and the rope 112 (113) suspended from the pulley 520 is extended. ) Can be performed more smoothly.

  Other specific examples of the cam type limiting means are shown in FIGS. In the rope traction device 501C of FIGS. 36 and 37, a cam-type limiting means 700 is mounted between the outlet portion 533, the pulley 520, and the latching portion 580 at the upper right portion on the front side of the support body 502C. Of the restricting means 700, reference numeral 701 denotes a support plate attached to the upper right portion on the front side of the support 502C. The support plate is bent such that the right portion is bent in a U shape and the rotation shaft 704 is rotatably attached to the inside. Part 705. The rotation shaft 704 is fitted with a base end portion of a cam 708 having a large number of teeth 707 protruding from an outer peripheral portion 706. The cam 708 is rotatable about a rotation shaft 704 as a rotation center in a direction approaching and separating from a rope passed through a rope groove of a rope contact portion described later (arrow m in FIG. 37). , N). A mainspring spring (not shown) that urges the cam 708 in the counterclockwise direction in FIGS. 36 and 37 is interposed between the rotating shaft 704 and the cam 708.

  A rotating shaft 709 is rotatably mounted near the center of the cam 708, and a base end portion of an L-shaped release operation member 710 is fitted to the rotating shaft 709. A columnar operation projection 711 protruding forward of the support body 502C is attached to a corner portion of the release operation member 710. By operating the operation projection 711 with a finger, the release operation member 710 is centered on the rotation shaft 709. (See arrows o and q in FIG. 37). The distal end side of the release operation member 710 is an engagement portion 712 that is bent in a J-shape and is detachably engaged with the outside of the bent portion 705 of the support plate 701. A mainspring (not shown) that constantly biases the release operation member 710 in the clockwise direction of FIGS. 36 and 37 is interposed between the rotation shaft 709 and the release operation member 710.

  The separation part 540C is a rope abutment part 545 that is extended in a slanting nose shape on the right side in FIGS. 36 and 37 and loosely inserted into the H-shaped groove 521 of the pulley 520. A rope groove 546 having an arcuate cross section is formed on the outer surface side of the portion 545. The pulley cover 550C has an opening 800 formed on the side surface in the upper right part of FIG. 36 so that the pulley cover 550C does not interfere with the pulley cover 550C even if the cam 708 and the release operation member 710 rotate.

  36 and 37, the suspension rope loading method to the rope traction device 501C will be described. First, the operation protrusion 711 of the limiting means 700 is operated with a finger, and the cam 708 is rotated and released. The rotation is performed in parallel, and the engaging portion 712 is engaged with the outside of the bent portion 705 as shown in FIG. The pulley cover 550C is opened, and one end of the hanging rope 112 (113) is inserted into the inlet passage 534 through the gap 544 between the inlet 532 and the outlet 533, and is slightly wound around the pulley 520 through the left side of the separating portion 540C. Hang, fit into the rope groove 546 of the rope guide portion 545 of the separation portion 540C, insert into the outlet passage portion 535 through the gap 544 between the inlet portion 532 and the outlet portion 533 (see FIG. 38), and then wind around the hooking portions 580 and 581 Multiply it.

  Then, the pulley cover 550C is closed and the operation protrusion 711 of the release operation member 710 is operated with a finger to disengage the engagement portion 712, and the rotation of the cam 708 and the release operation member 710 are performed in parallel. Then, the cam 708 is brought close to the hanging rope 112 (113) and the finger is released. In the cam 708, the outer peripheral portion 706 is urged to rotate in the rope direction by the spring, and the hanging rope 112 (113) is pressed against the rope contact portion 545 (see FIG. 39). When a force is applied to the suspension rope 112 (113) from the vicinity of the rope outlet of the pulley 520 (near the entrance of the rope groove 546) toward the outlet 533 (see the arrow t in FIG. 39), the cam 708 is rotated clockwise. However, since the outer peripheral portion 706 is away from the suspension rope 112 (113) fitted in the rope groove 546, the cam 708 easily rotates clockwise, and the outlet portion of the outlet side rope 112b (113b) Movement in the outward direction from 533 is allowed. On the other hand, when a force in the direction of pulling upward from FIG. 39 (see arrow U) is applied to the hanging rope 112 (113) from the inlet 532, an external force in the counterclockwise direction is applied to the cam 708. Since the direction of the cam 708 approaches the suspension rope 112 (113) fitted in the rope groove 546, the outer peripheral portion 706 bites into the suspension rope 112 (113) and restricts the movement, but between the cam 708 and the rope contact portion 545. Pinched).

In order to start pulling the suspension rope 112 (113) in order to raise the suspension type curing device 120, the exit side rope 112b (113b) is removed from the winding portions 580 and 581, and the rechargeable electric driver 515 inputs the input shaft. 507 is rotated forward. Then, the pulley 520 rotates in the forward direction, and at this time, the restricting means 700 permits the movement of the hanging rope 112 (113), so the inlet side rope 112a (113a) is smoothly pulled by the pulley 520, and the hanging rope The rope traction device 501C and the suspension type curing device 120 rise along 112 (113).
When it is desired to stop towing the hanging rope 112 (113), the driving of the input shaft 507 by the rechargeable electric driver 515 is stopped. When the entrance side rope 112a (113a) is pulled upward from the entrance portion 532 when viewed from the rope traction device 501C by the weight of the suspension type curing device 120 and the rope traction device 501C, the rope 546C is inserted into the rope groove 546 of the rope contact portion 545. The fitted exit-side rope 112b (113b) is pulled in the direction of the pulley 520 and a counterclockwise external force is applied to the cam 708, but the cam 708 is suspended because the outer peripheral portion 706 approaches the suspension rope 112 (113). The movement is restricted by cutting into the lowering rope 112 (113). Therefore, the exit side rope 112b (113b) is not pulled back to the entrance side, and the rope traction device 501C and the suspension type curing device 120 are not lowered.
In the state where the rope traction device 501C and the suspension type curing device 120 receive their own weights and the inlet side rope 112a (113a) is pulled upward in FIG. 39, the rope traction device 501C is lowered by pulling back in the pulling direction. In this case, the exit-side rope 112b (113b) is wrapped around the latching portions 580 and 581 and latched, and the manual rotation tool 590 is coupled to the input shaft 507 to perform normal rotation, and the suspension rope 112 (113) is rotated. The cam 708 is loosened, the operation protrusion 711 of the limiting means 700 is operated with a finger, the cam 708 is rotated and the release operation member 710 is rotated in parallel, and the engaging portion 712 is bent as shown in FIG. 705 engages outside. When the gripping force for gripping the outlet side rope 112b (113b) removed from the latching portions 580 and 581 is weakened, the pulley 520 is reversed by the pulling force of the inlet side rope 112a (113a), and the outlet side rope 112b (113b). ) Is pulled back to the entrance side, and the rope pulling device 501C and the hanging type curing device 120 are lowered by the hanging rope 112 (113).

36 and 37, it is possible to restrict the return side rope 112b (113b) from being pulled back while the suspension rope 112 (113) is being lifted or stopped without using the ratchet mechanism. In addition, the restriction can be released when it is desired to pull out and lower the entrance side of the hanging rope 112 (113). Further, since the limiting means 700 is provided between the outlet portion 533, the pulley 520, and the latching portion 580 in the support body 502C, the apparatus does not have to be large. In addition, since the suspension rope 112 (113) is sandwiched between the rope contact portion 545 and the cam 708, the entrance side of the suspension rope 112 (113) is pulled out (the direction in which the rope traction device 501C is lowered). Can be reliably restricted.
The restricting means 700 may be provided between the inlet portion 532 and the pulley 520 (in this case, the left side in FIGS. 36 and 37 of the separating portion is extended obliquely downward to form the rope contact portion. Just do it).

In the first embodiment, the lifting type curing device is lifted and lowered by two climbing devices. Instead of the lifting device, a rope lifting device such as a winch that lifts and lowers the hanging rope (FIG. 16). Thru various rope towing devices described in FIG. 39) may be provided on the rooftop, on a support, or on the ground.
For example, when two rope traction devices 501 shown in FIG. 16 are deployed on the roof, as shown in FIGS. 40 and 41, two support tools 201 and 207 are attached to the parapet 103 on the repair target side in the roof of the building 100. The four rope fixtures 901 to 904 are installed on the parapet 900 opposite to the parapet 103 (note that the safety ropes 101, 102, 104, and 105 are omitted in FIG. 40). The third worker arranged on the roof prepared two rope pulling devices 501-1 and 501-2 and two hanging ropes 200, 206 with the pulley cover 550 closed and the operation knob 571 fixed at the P1 position. Then, the lock member 553 of the rope pulling device 501-1 is pushed downward in the direction of FIG. 17 (in the direction of arrow a in FIG. 24 (1)), the engagement claw 558 is separated from the engagement grooves 538 and 539, and the lock is released. 550 is opened in the direction of arrow c in FIG.

One end of the hanging rope 200 is inserted into the inlet passage 535 through the gap 544 between the inlet 532 and the outlet 533 of the rope pulling device 501-1, and is slightly wound around the pulley 520 through the left side of the separating part 540 and separated. After being inserted into the outlet passage portion 535 through the gap 544 between the inlet portion 532 and the outlet portion 533 through the right side of the portion 540 (see FIG. 30), it is wrapped around the latching portions 580 and 581 and latched. Then, the pulley cover 550 is closed while the lock member 553 is pushed downward in FIG. 17 (see arrow b in FIG. 24 (1)), and the fitting portion 552 is fitted to the mated portions 536 and 537. When the depression of the lock member 553 is released, the lock member 553 is biased upward by the compression springs 554 and 555, and the engagement claws 558 are engaged and locked in the engagement grooves 538 and 539.
Similarly, the hanging rope 206 is loaded into the rope pulling device 501-2.

Two ropes 905 and 906 are stretched between the rope attachment hole 4 of the rope traction device 501-1 and the rope fixtures 901 and 902, and the rope attachment hole 4 and the rope fixture 903 of the rope traction device 501-2. Two ropes 907 and 908 are stretched between 904 to secure a fulcrum. The other end of the suspension rope 200 is wrapped around a sheave 203 and a tip sheave 204 provided on the upright support column 202 of the support 201 and hung on the ground. Similarly, the other end side of the suspension rope 206 is wound around the sheave 209 and the tip sheave 210 provided on the standing column 208 of the support 207 and hung on the ground.
The operator on the ground side connects one end side of the two ropes 3 and 4 to the lower end of the suspension rope 200 via the carabiner 205, and the other end side of the ropes 3 and 4 is a device of the suspension type curing device 120. Attached to the two rope attachment plates 145 and 146 on the left side of the main body 121. Similarly, one end side of the two ropes 7 and 8 is connected to the lower end of the suspension rope 206 via the carabiner 211, and the other end side of the ropes 7 and 8 is connected to the two rope attachment plates 147 on the right side of the apparatus main body 121.

On the other hand, when the suspension type curing device 120 is to be lowered, the restriction means 510 of the rope traction devices 501-1 and 501-2 is released, the hand holding the exit side ropes 200b and 206b is slightly loosened and suspended. Pulling force in the direction of the parapet 103 applied to the inlet side ropes 200a and 206a by the load of the type curing device 120 reverses the pulley 520, and the inlet side ropes 200a and 206a are moved outwardly of the inlet part 534 (to the parapet 103 direction). Just pull back.
40 and 41, since the workers A and B can work without putting the weight of the worker on the suspension type curing device 120, the suspension type curing device 120, the support tools 201, 207, The rope traction devices 501-1 and 501-2 do not need to be so large and robust, and the equipment burden can be reduced. In addition, the suspension ropes 200 and 206 can be pulled even on a rooftop without a commercial power source.
The rope traction devices 501-1 and 501-2 may be the rope traction devices 501A, 501B, and 501C shown in FIGS. 31, 33, and 36. Moreover, you may replace with other rope raising / lowering apparatuses, such as a winch.
Alternatively, the two rope pulling devices may be replaced by a rope lifting device such as a rope pulling device that can be pulled up and pulled up in conjunction with the two hanging ropes 200 and 206.

When installing a rope lifting device such as a winch on the ground, for example, for the left side where a pulley is suspended near the tip of each of the two supports attached to the parapet with a left and right spacing, and one end is installed on the ground. Two hanging ropes connected to the right rope lifting device (not shown) are respectively wound around the left and right pulleys, and the other ends of the two hanging ropes are suspended via the carabiner and the rope. What is necessary is just to connect with the right and left of a lowering type curing apparatus. When it is desired to raise and lower the suspension type curing device, a third operator arranged on the ground may raise and lower the suspension rope by operating the rope lifting device. Alternatively, the workers A and B who repair the outer surface of the building may move up and down by remote control.
Thus, by making it possible to raise and lower the suspension rope using the rope elevating device, the burden on the operator is reduced compared to raising and lowering with a combination of the elevating device and the electric tool as in the first embodiment. Moreover, when it is desired to perform work on the outer surface of the building from the roof side, the suspension type curing device can be quickly raised from the ground and installed near the roof.

Next, the operation of the second embodiment will be described.
Here, the building 100 has five or six stories, and the suspension type curing device 120 is installed at a position higher than the ground (for example, the height of the second floor) so that people can pass under the suspension type curing device 120. An example will be described in which a worker performs repair work or the like by rope access technology from the roof top to the height of the hanging type curing device 120.
Pulleys 222 and 223, 224 and 225 suspended in front of and near the tips of the two supports 220 and 221 mounted in advance on the parapet 103 on the roof of the building 100 at the same interval as the width of the hanging type curing device 120. Suspension ropes 226, 228, 227, and 229 are already wound, and the four safety ropes 101, 102, 104, and 105 secured on the roof are suspended over the parapet 103 and close to the ground. To do.

(1) Preparation Workers A and B move the suspension-type curing device 120 on the ground directly below the supports 220 and 221, and attach the carabiner 205 to one lower end of the suspension rope 226. The upper ends of the ropes 3 and 4 are hooked to the carabiner 205, and the lower ends are hooked to the rope attachment plates 145 and 146. Similarly, the carabiner 211 is hooked to one lower end of the hanging rope 227, the upper ends of the two ropes 7 and 8 are hooked to the carabiner 211, and the lower ends are hooked to the rope attachment plates 147 and 148 (see FIG. 43).

  Next, the curing sheet 250 is put into the hanging curing apparatus 120 and the lower end is fixed to the apparatus main body 121, and the horizontal bar 251 attached to the upper end is placed on the frame 133 of the back sheet curing unit 128. . One end side of the hanging rope 228 is attached near the left end of the reed 251, and one end side of the hanging rope 229 is attached near the right end of the reed 251 (see FIG. 44).

Each of the workers A and B pulls the other end side of the suspension ropes 226 and 227 downward, raises the suspension type curing device 120 to, for example, the height of the second floor, and sets the other end side of the suspension ropes 226 and 227 to the ground. (See FIG. 45). Subsequently, each of the workers A and B pulls the other end side of the suspension ropes 228 and 229 downward, pulls the upper end of the curing sheet 250 up to the vicinity of the pulleys 223 and 225 of the support members 220 and 221, and the suspension rope 228. 229 is fixed to the ground (see FIGS. 46 and 47).
Thereafter, the workers A and B move to the roof, and attach the upper left corner and the upper right corner of the curing sheet 250 to the side of the building 100 in the support tools 220 and 221, respectively. Thereby, it cures so that the space above the suspension type curing device 120 outside the outer surface of the building 100 is surrounded by the curing sheet 250 (see FIG. 47).

(2) Work such as repair Worker A on the roof hooks the safety lanyard on the main side of the safety belt attached to the lifting device (not shown) attached to the safety rope 101 to secure the lanyard on the backup side. Hang on a fall prevention device (not shown) attached to the rope 102, get over the parapet 103 above the suspension type curing device 120, enter the space between the outer surface of the building 100 and the curing sheet 250, and a safety rope While hanging on 101, work such as repair on the outer surface is sequentially performed from the roof side of the building 100 to the hanging type curing device 120. The worker B also attaches the lanyard on the main side of the safety belt attached to himself / herself to a lifting / lowering device (not shown) attached to the safety rope 104, and the fall prevention device attaches the lanyard on the backup side to the safety rope 105. (Not shown), climbs over the parapet 103 above the suspension type curing device 120, enters the space between the outer surface of the building 100 and the curing sheet 250, and hangs on the safety rope 104 while Work such as repair on the outer surface is sequentially performed from the roof side to the hanging type curing device 120 (see FIG. 42).

Repair members, debris, etc. generated by the work or accidentally dropped work tools hit the curing sheet 250 and fall into the suspension type curing device 120 or directly into the suspension type curing device 120. As a result, the outside of the curing sheet 250 and the fall or scattering to the ground are prevented.
Even when the work approaches the suspension type curing device 120, the workers A and B make sure that their weight hardly hangs on the suspension type curing device 120.
When the work is completed, the workers A and B descend from the side of the suspension type curing device 120 to the ground, remove the suspension ropes 226 and 227 from the ground side, lower the suspension type curing device 120 to the ground, and suspend them. The fixing of the lowering ropes 228 and 229 on the ground side is removed, and the curing sheet 250 is lowered to the hanging type curing device 120.

According to the second embodiment, workers A and B are supported by safety ropes 101 and 102, 104 and 105 hanging from the roof of the building 100, and the buildings 100 are sequentially installed from the roof to the ground. When performing work such as repair on the outer surface, a work space is opened between the hanging type curing device 120 installed below and the outer surface of the building 100 from the vicinity of the roof on the outer surface of the building 100 to the hanging type curing device 120. However, the work can be performed while being surrounded by the curing sheet 250 arranged. When working from near the rooftop to the hanging type curing device 120, work tools that have been accidentally dropped, such as debris such as walls and repair members, hit the curing sheet 250 and fall into the hanging type device 120. Or dropped directly into the hanging type curing device 120, the falling or scattering of the curing sheet 250 to the outside or the ground is prevented.
In addition, since the hanging type curing device 120 is not lifted or lowered during work such as repair, the work can be rapidly advanced.
Further, since the weights of the workers A and B are not applied to the suspension type curing device 120, it is not necessary to make the suspension type curing device 120 and the support members 220 and 221 robust, and the suspension type curing device 120 can be used. Since the weight is light, it can be moved up and down manually, and the equipment burden can be reduced.

In the second embodiment described above, a hanging type curing sheet (mesh sheet) is used, but it may be replaced with a hanging type curing net.
In addition, the case where the suspension type curing device is installed near the ground of the building has been described as an example, but it is installed near the roof of the building or in the middle of the height direction, and the curing sheet is suspended from the roof. You may make it arrange | position to a curing apparatus.
In addition, when the work target range is below the rooftop, it is not always necessary to raise the upper end of the curing sheet to the vicinity of the rooftop, leaving a work space between the building exterior and the upper part of the suspension-type curing device. You may make it arrange | position from a desired height to a suspension type curing device. Further, instead of fixing the lower end side of the curing sheet in the hanging type curing apparatus, the curing sheet may be taken out of the hanging type curing apparatus and fixed at a certain height position near the ground or from the ground.
Place a curing sheet or curing net from the top of the suspension-type curing device to the vicinity of the suspension-type curing device, or from the top of the suspension-type curing device to the bottom of the suspension-type curing device, while ensuring a working space for the exterior of the building. By installing, even if fragments such as walls and repair members, work tools, etc. are dropped when working above the suspension type curing device, scattering around the building can be prevented.

In the second embodiment described above, the lifting type curing device and the curing sheet are manually raised and lowered. However, the winch for raising and lowering the hanging rope, the rope lifting device such as the rope pulling device shown in FIG. May be installed on the rooftop, on a support or on the ground.
When four rope lifting devices are installed on the roof, for example, as shown in FIG. 48, the left hanging rope 300 having one end connected to the left first rope lifting device (not shown) is supported on the left side. One of the two ropes 3 and 4 is suspended from the lower end of the hanging rope 300 via the carabiner 205 while hanging around the sheave 303 provided on the standing column 302 of the tool 301 and the sheave 304 provided near the tip. The other ends of the ropes 3 and 4 are attached to the two rope attachment plates 145 and 146 on the left side of the apparatus main body 121. Similarly, a right hanging rope 305 having one end connected to a second rope lifting device (not shown) for the right side and a sheave 308 provided on the upright column 307 of the right support 306 and a sheave provided on the tip. The rope hangs downward while being wound around the wire 309, connects one end of the two ropes 7 and 8 to the lower end of the hanging rope 305 via the carabiner 211, and connects the other end of the ropes 7 and 8 to the right side of the apparatus main body 121. Are attached to the two rope attachment plates 147 and 148.

  In addition, a left hanging rope 311 having one end connected to a third rope lifting device (not shown) for the left side is provided near the sheave 312 provided on the upright column 302 of the left support 301 and the tip. While hanging around the sheave 313, it hangs downward and attaches the left end of the reed 251 of the curing sheet 250 to the lower end of the hanging rope 311. Similarly, a sheave 315 provided on the upright column 307 of the right support 306 and a sheave provided on the tip of the right hanging rope 314 having one end connected to a fourth rope lifting device (not shown) for the right side. While hanging around 316, it hangs downward and attaches the right end of the reed 251 to the lower end of the hanging rope 314.

When it is desired to raise and lower the suspension type curing device 120, a third operator disposed on the roof may raise and lower the suspension ropes 300 and 305 by moving up and down the first and second rope lifting devices. Alternatively, the workers A and B who repair the outer surface of the building may move up and down by remote control. Similarly, when it is desired to raise and lower the upper end of the curing sheet 250, a third operator arranged on the roof may raise and lower the hanging ropes 311 and 314 by moving up and down the third and fourth rope lifting devices. . Alternatively, the workers A and B who repair the outer surface of the building may move up and down by remote control.
Even in this case, since the workers A and B can keep the weight of the worker from being applied to the suspension type curing device, the suspension type curing device 120, the support tools 301 and 306, and the first to fourth ropes. The lifting device does not need to be so large and robust, and the equipment burden is small.
Instead of the first and second rope lifting devices, a rope lifting device capable of feeding and lifting the two hanging ropes 300, 305 in conjunction with each other may be used. Instead of the rope lifting device, a rope lifting device capable of feeding and lifting the two hanging ropes 311 and 314 in conjunction with each other may be used.

  When rope lifting devices such as winches and rope pulling devices are installed on the ground, the ground fixing sides of the suspension ropes 226 to 229 in FIG. 42 are respectively used as first to fourth rope lifting devices (not shown). Just connect. When it is desired to raise and lower the suspension type curing device 120, a third operator arranged on the ground moves up and down the first and second rope lifting devices, and the suspension type curing device 120 of the suspension ropes 226 and 227 is operated. What is necessary is just to raise / lower the side (carabiner 205, 211 side). Alternatively, the workers A and B who repair the outer surface of the building may move up and down by remote control. When the hanging type curing sheet 250 is to be raised and lowered, the third operator arranged on the ground moves up and down the third and fourth rope lifting devices, and the hanging ropes 228 and 229 side (the side 251 side) ). Alternatively, the workers A and B who repair the outer surface of the building may move up and down by remote control.

In this way, by making it possible to lift and lower the suspension rope that suspends the suspension type curing device using the rope lifting device and the suspension rope that suspends the curing sheet separately, the roof side of a high-rise building and the height direction If you want to install a suspension type curing device in the middle and place a curing sheet from near the roof to the hanging type curing device, or from the desired height above the hanging type curing device to the hanging type curing device The suspension type curing device can be quickly installed at a desired height, and the curing sheet can be arranged in a desired range. In these cases, the lower part of the curing sheet may be taken out of the hanging type curing apparatus, and the lower end may be fixed near the ground.
Also, when you want to lower the hanging type curing device sequentially as the work progresses from the roof of a high-rise building, use a rope lifting device to place a curing sheet on the hanging type curing device and close to the roof As the repair work progresses to the exterior of the building, the lower part of the curing sheet is lowered by lowering the hanging curing device while keeping the upper end of the curing sheet close to the support. The curing sheet can be arranged in the range from the rooftop to the suspended curing device that is pulled out from the device. Also in this case, the lower part of the curing sheet may be taken out of the hanging type curing apparatus, and the lower end may be fixed near the ground.
