Description

  The present invention is a winch for moving a wire rope suspended between wall surfaces, a ceiling portion, etc., and is used for performing various work sites by moving a winch along a suspended wire rope. To move the construction site, the UV cut net or sheet member that covers the outdoor pool, the sheet member that is covered to prevent rain at the construction site such as the retaining wall construction, and the sheet member of the temporary roof The present invention relates to a moving system using a winch to be used and a moving system using a net or seat winch.

  One example of a moving system using a winch is a wall inspection work for a building. As this wall inspection work, there is a system that moves the operator up and down directly / indirectly while moving the wire rope suspended in the vertical direction with a winch, and as another example, as a blame for hotels etc. There is a system that moves down by using a wire rope installed on a winch fixed outdoors from the wall of a high place.

  In addition, as a moving system using a net or sheet winch, a temporary roof is provided in a desired space of the work place by using a net or sheet in order to avoid strong sunlight on the construction site and avoid rain, and the net or sheet. There is a system that opens and closes using a winch, and as another device, a plurality of support ropes installed in parallel between the support posts standing in the installation space and extending in parallel are stretched between adjacent support ropes. There is a system that slides and opens the membrane roof by moving the traversing cable and the opening and closing cable with a winch.

  For the inspection of the wall surface of the construction, an arm provided to project laterally from the wall surface, a winch for winding the wire rope attached to the arm, a cargo bed fixed to the wire rope of the winch, and an arm And an auxiliary wire rope provided between the ground and the ground part, and the operator checks the wall surface by raising and lowering the loading platform on which the operator is placed by drawing or winding the wire rope from the winch. At this time, in terms of safety, the auxiliary wire rope and the wire rope from the winch are always in tension (tensioned), and the safety is ensured by using an auxiliary brake. In addition, as for blame, it is composed of a column provided outdoors from the wall of a high place, a winch fixed to the column, and a wire rope provided on the winch, and a person with a safety belt attached is wired. There is a system that connects to the tip of the rope and operates the winch to lower the wire rope and blame it.

The temporary roof is composed of two guides provided in parallel to the installation location, a plurality of beam members mounted in a direction that is perpendicular to the guides and parallel to each other and movable to the guides, and between the beam members. A seat member attached to the one end, a one end pulley attached to the one end side opposite to the guide, a second end pulley attached to the other end side opposite to the guide, and one end side pulley and the other end side pulley. It consists of a wire rope provided in a loop shape and a manual winch that moves the wire rope. By moving the wire rope stretched on the pulley with the manual winch forward and backward, the guide is provided in parallel. A plurality of beam members are moved along, and a sheet member provided on the beam members is opened and closed.
Other devices slide and open the membrane roof by moving a traversing cable and an opening and closing cable with a winch. The load supported by the columns is supported by a lightweight load such as a support rope or a membrane roof.

  However, since the winch used for the above wall inspection etc. is used for winding the wire rope, it must be used with the wire rope always in tension. If there is even a slight slack, the loading platform will drop suddenly, so it is necessary to constantly check the tension of the wire rope, and it is necessary to install a separate brake mechanism in the winch or as a separate body.

  Similarly, when using an endless winch with a separate wire rope winding device, tension is applied to both the wire rope draw-out side and the wire rope take-in side from the winch. Otherwise, there was a drawback that the wire rope could not be moved smoothly.

  In addition, the seat member attached to the beam member of the temporary roof is only attached by fixing the pulley to the support column. When the installation space is large, the load of the sheet member on the wire rope provided in a loop shape As a result, when the wire rope moves in the winch, there is a case where slack occurs on one side of the wire rope, and the wire wire cannot be moved smoothly and the sheet member cannot be opened and closed.

  In addition, in the case of a membrane roof stretched between adjacent support ropes, the membrane roof is divided into a plurality of parts, so that the weight of the material such as the support rope and the membrane roof is reduced. Due to this, when the membrane roof is opened and closed, the traversing cable and the opening and closing cord may become slack, and the support rope may not move smoothly as described above, and the membrane roof may not be opened and closed. Need.

  In order to prevent loosening of the wire rope (supporting rope), it is generally used to attach each pulley using a tension mechanism and always provide the wire in a tension state, but in this case, the structure becomes complicated, There was a problem that the entire apparatus was expensive.

  The present invention uses a winch that can move the wire rope smoothly without causing a problem of the tension of the wire rope, which has been a drawback of the above-described conventional apparatus, and without considering the load of the net or the sheet. The above-described problems are solved by providing an operating system using a net or seat winch.

Means to solve the problem

  The present invention is a moving system using a winch that performs various operations by moving a suspended wire rope with a winch, and moves the wire rope while eliminating the slack generated in the wire rope with the winch. This is a moving system using a winch.

  Moreover, it is a moving system using the winch which moves a winch along a wire rope, eliminating the slack which generate | occur | produces in a wire rope along the suspended wire rope with a winch.

  In addition, the winch eliminates slack due to the load of the net or sheet on the wire rope provided for lifting the net or sheet for covering the space or the net or sheet for cutting wind and ultraviolet rays. While the wire rope is moved endlessly, the net or sheet is opened and closed to move the net or sheet winch.

  In addition, the net or sheet is divided into a plurality of pieces, and the divided nets or sheets are moved in an endless manner along the dividing direction so that the divided nets or sheets are in the same direction. It is a moving system using a net or sheet winch that opens and closes in the opposite direction.

Effect of the invention

  The moving system using the winch of the present invention moves using a winch fixed with a wire rope suspended endlessly in a vertical direction or a horizontal direction with respect to the ground. When a sufficient load is not applied to the wire rope when the wire rope is moved, the wire rope is slackened. The winch moves the wire rope while eliminating the slack of the wire rope.

  In addition, when a winch is moved along a wire rope suspended in a vertical or horizontal direction with respect to the ground, even if the suspended wire rope becomes slack, the slack of the wire rope is eliminated by the winch. While moving the winch, various work is performed.

  Moreover, when opening and closing a net | network or a sheet | seat, a support | pillar is standingly arranged on the outer periphery of an installation place, and a wire rope is suspended endlessly through the winch between this support | pillar. The method of suspending this wire rope in an endless manner is also possible to hang a plurality of wire ropes by suspending wire ropes between struts, and to hang them with one wire rope But it is possible.

  Next, the net or sheet is directly or indirectly connected to the opposing wire rope, and the wire rope is moved directly or indirectly along the wire rope by moving the wire rope by operating the winch fixed to one column. The net or sheet can be freely opened and closed.

  Since the load on the net or sheet is applied directly or indirectly to the wire rope suspended endlessly, when the net or sheet is opened and closed, when the wire rope is moved by driving the winch, the wire to the winch Since the load applied to the wire rope is different between the rope take-in side and the take-out side (with respect to the drive unit of the winch), slack is likely to occur particularly on the take-out side of the wire rope to the winch. In the present invention, the wire rope can be moved endlessly while eliminating the slack at the winch portion, so that the net or the sheet can be opened and closed smoothly.

  The loosening of the wire rope in the winch described above will move while the wire rope is always in tension in the winch. It is possible to eliminate the slack in the winch without causing a problem and to move the wire rope smoothly.

The invention's effect

  Since the present invention can move the wire rope while eliminating the slack of the wire rope with the winch, there is no trouble caused by the slack of the wire rope, and it is particularly effective in terms of safety, and can handle various work can do.

  Also, even if the wire rope is subjected to a net or sheet load, and the wire rope can be moved even if the wire rope is taken out or taken into the winch, the trouble can be caused by the slack of the wire rope. Therefore, the need for maintenance can be minimized and maintenance costs can be reduced.

  In addition, the smooth opening and closing movement of the net or seat allows the effects of the wind to be eliminated by quickly opening the net or seat on a windy day such as a gust of wind. I can hold it down.

  Furthermore, since the load of the net or sheet on the wire rope can be eliminated by the winch, the plurality of tension means that are the wire rope and net or sheet suspension equipment that were required in the past are not required, and it was installed in a large space. In particular, the installation cost can be greatly reduced.

  The movement system 1 using the winch of the present invention is provided on a wire rope 3 having one end fixed to an upper portion such as a ceiling via a connector 2 and the other end hanging downward, and the wire rope 3. The winch 4 and a key-like hook 5 provided at the lower end of the winch 4 are configured to move the winch 4 up and down along the wire rope 3 when the winch 4 operates.

  The basic configuration of the winch 4 is configured to wind the wire rope 3 around a winding ring 6 that is rotationally driven by a driving source (manual or automatic), and to move the wire rope 3 endlessly. Regarding the taking-in and taking-out of the wire rope 3 to and from the winding ring 6, three rotatable guide rings 7 and the role of the route of taking-in and taking-out of the wire rope 3 are provided in the vicinity of the guide ring 7. (Each road is formed into a groove shape or a cylindrical shape, and the diameter of the wire rope 3 is substantially the same as the diameter of the wire rope 3), the wire rope 3 is taken in along the guide guide 8, The wire rope 3 is moved to the winding ring 6 while holding and pressing the wire rope 3 between the guide guide 8 and the guide ring 7, and the wire rope 3 is wound around the outer periphery of the winding ring 6 by driving the winding ring 6. The wire rope 3 is taken out again along the guide guide 8, and the wire rope 3 is removed while holding and pressing the wire rope 3 between the guide guide 8 and the guide ring 7. Taken out from the switch 4.

  When the wire rope 3 is wound around the outer periphery of the take-up ring 6, tension is provided at both ends, and the wire rope 3 is attached to the outer periphery side of the take-up ring 6 with a pressing body 9 provided along the outer periphery of the take-up ring 6. Therefore, the wire rope 3 can be reliably moved without rotating the wire rope 3 when the winding ring 6 is rotationally driven.

  That is, the wire rope 3 is clamped by the guide guide 8 and the guide ring 7, pressed, and the wire rope 3 by the pressing body 9 is pressed against the outer peripheral side of the take-up ring 6 to release the slack of the wire rope 3. Even if slack occurs on the intake side of the rope 3, the wire rope 3 can be moved endlessly by the winch 4 regardless of the slack of the wire rope 3.

  The mobile system 1 using the winch of the present invention is configured as described above. Next, an example of using the mobile system 1 will be described.

  When raising and lowering a lighting fixture provided with a ceiling portion of an indoor facility for sports or the like having a large space portion, first, four connecting tools 2 are attached to the ceiling portion at predetermined intervals, and wires are connected to the connecting tools 2. A winch 4 to which the other end side of the rope 3 is fixed is attached. Each wire rope 3 is provided with a winch 4, the four corners of a rectangular frame 20 provided with a lighting fixture are connected to the hook 5 of the winch 4, and the winch 4 is operated to move the frame up and down. Moving. The winch is operated using, for example, a control panel (not shown) and a wireless remote control panel (not shown). At this time, if the conventional winch has the same configuration as described above, the frame body 20 can be moved up and down smoothly unless the initial setting is made in a state where sufficient tension is applied to the wire rope 3 provided in each winch. In addition, when the wire rope 3 used for one winch is slackened during the up-and-down movement, there is a problem that it is necessary to reset the initial setting. However, the moving system 1 using the winch of the present invention. Is used, it is sufficient to adjust the length of the wire rope 3 even if the wire rope 3 is not sufficiently tensioned at the initial setting, and the initial setting can be performed easily, and the elevator is moving up and down. Even if slack occurs in one of the wire ropes 3, the winch 4 can be used to eliminate the slack, so there is no need to re-initialize and use continuously. Can.

  The looseness of the wire rope 3 by the winch 4 is solved by taking the wire rope 3 taken into the winch 4 along the guide guide 8 and holding and pressing the wire rope 3 by the rotation of the guide guide 8 and the guide ring 7. While moving the wire rope 3 to the winding ring 6, the winding rope 6 is driven to wind the wire rope 3 around the winding ring 6, and the wire rope 3 is taken out again along the guide guide 8 and guided. Since the wire rope 3 is taken out from the winch 4 while holding and pressing the wire rope 3 by the rotation of the guide 8 and the guide ring 7, it is in a constant state regardless of the looseness of the wire rope 3. The wire rope 3 can be moved. Further, since the wire rope 3 wound around the outer periphery of the winding ring 6 is pressed against the outer peripheral side of the winding ring 6 by the pressing body 9, the pressing body 9 is rotated when the winding ring 6 is driven to rotate. The wire rope 3 can be reliably moved without idling while moving in a tensioned state in the rotational direction 6.

  In the above embodiment, the lighting apparatus is used for lifting, but the use of the present invention is not limited to this. For example, for lifting a stage apparatus, for lifting a building member, or for other lifting Can be used as

  Moreover, although the implementation of the present invention is configured to move the winch 4 in the vertical direction along the wire rope 3, the wire rope 3 is suspended between the wall surfaces (parallel to the ground), and the wire rope 3 can be configured to move in the horizontal direction, and in this case, it is possible to move the net or the sheet 16 in the horizontal direction by hooking the tip end side of the net or the sheet 16 on the wire rope 3. A safety suspending rope 21 is provided above, a loading platform 22 is movably provided on the safety suspending rope 21, and a handle 23 provided on the take-up ring 6 is rotated so as to move laterally. In addition, two winding rings 6 are provided on the winch 4, and the winch 4 moves laterally along the wire rope 3 in one winding ring 6 and stops at a predetermined position. By using the clutch mechanism or the like to switch to the other winding ring 6 and rotating the winding ring 6, the hook 5 is configured to be lifted and lowered from the winch 4, so that the moving system 1 using the winch can be used. Can be further expanded.

  Further, for example, the winch 4 can be fixed upward, and the wire rope 3 can be moved up and down by operating the winch 4. In this case (when the winch 4 is fixed), even if the wire rope 3 is slack in the initial state where no load is applied to the wire rope 3, the wire rope 3 can be smoothly moved while being eliminated by the winch 4.

  Next, an embodiment using the moving system 1A using a net or sheet winch will be described.

  The moving system 1A using a net or a seat winch is endless along a direction in which the sheet 16 is covered with a plurality of pulleys 14 provided on a support (not shown). It is provided so that its end side is moved in the forward and reverse directions by the winch 4. And the sheet | seat divided | segmented into plurality is attached between the wire ropes 3 suspended in the parallel direction (between A and B). As for the method of attaching the sheet 16, the endless suspension direction of the wire rope 3 can be changed according to the opening / closing direction of the plurality of sheets 16, and the sheet 16 can be attached freely in the same direction or in the opposite direction.

  The basic configuration of the winch 4 is the same as the winch 4 used in the moving system 1 using the winch.

  The sheet 16 is attached to the wire rope 3 by attaching the sheet 16 to the suspension wire 17 suspended in parallel along the opening and closing direction so that the sheet 16 is waved via the insertion body 18. It fixes to the wire rope 3 via the fixing tool 19. In addition, the attachment method to the wire rope 3 of the sheet | seat 16 is not limited to this, For example, it is also possible to attach the sheet | seat 16 to the wire rope 3 via the insertion body 18 and the fixing tool 19 directly.

  The mobile system 1A using the net or seat winch is configured as described above, and the case where the system 1A is used for an outdoor pool will be described next.

  Struts are erected on the outer periphery of the pool at regular intervals, pulleys 14 are attached between the opposing struts, wire ropes 3 are stretched between the plurality of pulleys 14, and the winches 4 are taken in and out of one pillar, and are endlessly formed. Hanging. Depending on the size (installation area) of the pool, the same wire rope 3 suspended endlessly and the winch 4 moving the wire rope 3 are suspended throughout the pool, A suspension wire 17 is fixed to the lower side of the attachment position of the pulley 14.

  Next, the divided | segmented sheet | seat 16 which has a UV cut function is attached along the same moving direction of the wire rope 3 suspended. The sheet 16 is attached by inserting the insertion bodies 18 attached at equal intervals on opposite sides of the sheet 16 through the suspension wires 17 provided in parallel, and attaching the sheet 16 in a wave shape. Fixing tools 19 provided at both ends of the tip in the direction of movement 16 are fixed to the wire rope 3 in the same direction of movement.

  The winches 4 provided on the support columns at the predetermined intervals are driven in synchronization with an operation panel (not shown), for example. As for the drive source of the winch 4, a manual type or an electric type is selected depending on the size of the installation area of the seat 16, and when it is difficult to secure a power source, a solar power source or a rechargeable assist drive is provided in consideration of the environment. Winch 4 is selected.

The attached seat 16 drives each winch 4 when using the pool, and moves the wire rope 3 to move the fixture 19 along the wire rope 3. The seat 16 moves along the suspension wire 17. Moves and covers the pool with the divided sheets 16.
Further, when the wind becomes strong in the covered state, the fixing tool 19 moves in the reverse direction along the wire rope 3 by driving the winches 4 in the reverse direction and moving the wire rope 3 in the reverse direction. The sheet 16 moves along the wire 17 in the storage state, stores all the divided sheets 16 and opens the pool. For this reason, the pool can be used in a safe state without being affected by wind.

  When the wire moves in the positive direction (covering direction for closing the sheet 16), the load of the sheet 16 is applied to the side of the wire rope 3 that is taken into the winch 4 (direction b), and the wire rope 3 is always pulled. However, since the load of the sheet 16 is not directly applied to the side of the wire rope 3 that is pulled out from the winch 4 (direction a), slack occurs. In addition, when the wire rope 3 moves in the reverse direction (the storage direction in which the seat 16 is opened), a load is applied to the take-in side (direction a) of the wire rope 3 to the winch 4 and loosening occurs. The side to be pulled out (b direction) is always pulled by the load of the sheet 16.

  Conventionally, as a means for eliminating the slack, the pulley 14 is attached to the support column via a tension to try to eliminate the slack. However, in the case of the seat 16 having a large outdoor installation area, only the tension is obtained although it is divided. However, there are many cases where the slack cannot be resolved. Therefore, in the present invention, the slack is eliminated by the winch 4 that moves the wire rope 3, and the opening and closing movement of the sheet 16 can be performed smoothly.

  Specifically, in the case of the wire rope 3 on the take-in side to the winch 4 that is always pulled and the wire rope 3 that is on the pull-out side from the winch 4 in which the slack occurs, the wire rope 3 in the pulled state is guided. When the wire rope 3 is taken in along the groove of the guide 8 and is taken in such a manner that the wire rope 3 is sandwiched or / and pressed between the guide guide 8 and the guide ring 7, and the wire rope 3 is taken up by the take-up ring 6 By pressing the wire rope 3 to the outer peripheral side of the winding ring 6 by the pressing body 9, the rotational drive of the winding ring 6 is transmitted to the wire rope 3 without spinning, and further, the wire rope 3 The pull-out side is pulled out along the groove of the guide guide 8 in the same manner as the intake side, and the wire rope 3 is sandwiched between the guide guide 8 and the guide ring 7 or And pull out so as to press. For this reason, the pulled wire rope 3 can also be taken into the winch 4 in a fixed state, and the wire rope 3 can be pulled from the winch 4 regardless of the slackness of the wire rope 3 on the pulling side from the winch 4. The drawer can be moved.

  When the loose wire rope 3 is taken into the winch 4, the wire rope 3 is taken along the groove of the guide guide 8, and the wire rope 3 is sandwiched between the guide guide 8 and the guide ring 7 or / and / or. Since it is taken in like a press, it can be taken in a certain state while sufficiently eliminating the slack of the wire rope 3 alone, and the wire rope 3 is wound around the winding ring 6. At that time, by pressing the wire rope 3 to the outer peripheral side of the winding ring 6 by the pressing body 9, the rotational driving of the winding ring 6 can be transmitted to the wire rope 3 without being idle. Further, the drawing side of the wire rope 3 can be drawn out along the groove of the guide guide 8 in the same manner as the taking-in side, and the wire rope 3 can be drawn and / or pressed by the guide guide 8 and the guide ring 7.

  Since the above-described wire rope 3 take-in side, the drive part of the take-up ring 6 and the draw-out side are provided with a smooth moving means of the wire rope 3, the wire rope 3 take-in side to the winch 4 is provided. In order to enable smooth movement of the wire rope 3 even if slack is generated on either the drawer side or on both sides of the intake side and the drawer side, it has been conventionally required. Various tensions on the wire rope 3 are not required.

  Accordingly, it is not necessary to provide various tension-attached pillars and the like, and the equipment cost can be greatly reduced. Also, since the entire structure is simple, the maintenance cost can be significantly reduced.

  In addition, since the seat 16 can be securely stored against the influence of the wind peculiar to the outdoors, the safety and durability are remarkably excellent.

  In the above embodiment, the method of moving the divided sheets 16 at the same time has been described. However, in the present invention, the movement of the sheets 16 is controlled by the control panel so that only a part of the divided sheets 16 is moved open. Of course it is also possible.

  In the above embodiment, the moving system 1A using a net or sheet winch is used for the UV cut sheet of the pool in a system in which the sheet 16 is provided in parallel to the installation surface. However, the net or sheet winch of the present invention is used. The use of the used mobile system 1A is not limited to this. For example, it can be used as follows.

  A pulley 14 is attached to the upper side between adjacent columns 24 among the plurality of columns 24 erected, a wire rope 3 is stretched between the pulleys 14, and a wire is attached to a winch 4 attached to the lower side of one column 24. The rope 3 is hung, and a hanging wire 17 is hung parallel to the lower side close to the wire rope 3, and the sheet 16 is hung in the vertical direction via the insertion body 18 on the hanger wire 17. The fixing tools 19 provided at both ends of the leading end in the moving direction of the sheet 16 are fixed to the wire rope 3.

  The use of the sheet 16 suspended in the vertical direction is used, for example, for fog prevention on a highway. That is, the seat 16 is suspended in the vertical direction so as to face both sides of the highway.

  When fog occurs on the expressway, for example, the winch 4 is actuated by sensing with a sensor, the wire rope 3 is moved in a loop shape, and the sheet 16 fixed to the wire rope 3 at the tip side is moved in the vertical direction. Move to prevent fog from entering the highway, and if the wind is strong, move the seat 16 in the vertical direction in the opposite direction and store the seat 16 on the side of one column 24 to influence the wind. Can be avoided.

  Also in this case, as in the case of the embodiment, since the slack of the wire rope 3 can be eliminated by the winch 4, the need for maintenance can be drastically reduced as compared with the elimination of the slack by the conventional tension configuration.

  In addition, when the wire rope 3 is looped, it can also be spanned between the plurality of support columns 24, so that the moving system 1A using a net or seat winch can be simplified. It was possible to reduce the cost.

  As described above, the case where the sheet 16 is moved in parallel with respect to the installation surface and the case where the sheet 16 is moved in the vertical direction have been described. However, in the present invention, the sheet 16 can be moved by a combination thereof.

  In other words, the installation space is framed with a plurality of columns 24 and beams 25, and the suspension wires 17 are stretched over each surface (roof portion A, B surface, side wall portion C surface, D surface, E surface). The sheet 16 is suspended, and the wire rope 3 is looped over the adjacent upper side of the suspension wire 17 so that the sheet 16 on each surface can be opened and closed independently (for example, It is also possible to open only the sheet 16 on the D surface and close the other surface).

  At the work site, the entire space of the work site is framed with pillars and beams in a tent style, and the sheets 16 divided into all the faces are suspended respectively (the winch 4 is changed depending on the length of the sheet 16 and the moving direction of the sheet 16). A predetermined number is installed (a plurality of divided sheets 16 are moved by one winch 4 (even if the moving directions are different)), and the wire rope 3 is looped around the winch 4 respectively. Each winch 4 is independently controlled by a control panel (not shown).

  And only necessary surfaces (for example, on summer days, only the working part is closed and moved to avoid sunlight, and other parts are moved to open) Is possible.

  Also in this case, even if slack is generated in each wire rope 3, the slack can be eliminated at the winch 4 portion, so that maintenance is not required, and it can be used without delaying work.

  The use of the moving system 1A using the net or sheet winch of the present invention is not limited to the above-described embodiment, and can be used at any construction site where a large area net or sheet is used. As an example, a frame (scaffold) is provided for the entire building for repair and inspection of an apartment house, etc., a net or sheet is attached along the frame, and the net or sheet is installed so as to be opened and closed using a winch. It is also possible to configure.

Further, the net or sheet is divided into a plurality of pieces, and the divided nets or sheets are moved endlessly using a winch by respectively suspending the wire ropes suspended along the dividing direction. 3. The moving system using a net or sheet winch according to claim 2, wherein the moving system opens and closes in the same direction or opposite direction of the sheet.

The movement system using the winch of the present invention moves endlessly by driving the winding ring of the winch fixed to the wire rope suspended endlessly in the vertical or horizontal direction with respect to the ground. . When a sufficient load is not applied to the wire rope when the wire rope is moved, the wire rope is slackened. The winch moves the wire rope while eliminating the slack of the wire rope.

In addition, when the winch is moved by driving the winding ring of the winch along the wire rope suspended in the vertical or horizontal direction with respect to the ground, the suspended wire rope is slackened. However, various operations are performed by moving the winch while eliminating the slack of the wire rope with the winch.

Since the load of the net or sheet is applied directly or indirectly to the wire rope suspended endlessly, when the net or sheet is opened and closed, when the wire rope is moved by driving the winding ring of the winch, Because the load applied to the wire rope is different between the wire rope take-in side to the winch and the take-out side (with respect to the drive unit of the winch), slack may occur particularly on the wire rope winch take-out side. Cheap. In the present invention, the wire rope can be moved endlessly while eliminating the slack at the winch portion, so that the net or the sheet can be opened and closed smoothly.

The loosening of the wire rope in the winch is achieved by pressing the wire rope between a plurality of guide rings and guide guides provided on the winch , and a pressing body in which tension is provided on both ends on the outer periphery of the winding ring. Since the wire wire rope always moves in a tensioned state by moving with the tension applied in the direction of rotation of the winding ring , the wire rope winch to the winch or slack on the intake side Even if there is a problem, it is possible to eliminate the slack in the winch without causing a problem and to move the wire rope smoothly.

The present invention uses a winch to move each net or sheet divided between a plurality of endless wire ropes according to the opening and closing direction in order to cut wind and ultraviolet rays or to cover the space. Or, in a moving system using a seat winch, the wire rope is clamped by a plurality of guide rings and guide guides provided on the winch, and the outer circumference of the winding ring With a pressing body with tension on both ends, it moves endlessly with tension applied in the rotational direction, eliminating the looseness on the take-out side or intake side of the wire rope and moving the wire rope use the winch, characterized in that for opening and closing movement in a direction or opposite to the direction that is divided the net or sheet to It was a mobile system.

In order to cut the wind and ultraviolet rays, or to cover the space, each net or sheet provided between endless wire ropes and divided into a plurality of nets or sheets is moved according to the opening and closing direction using a winch . Since the load is applied directly or indirectly to the wire rope suspended endlessly, when the wire rope is moved by driving the winding ring of the winch during opening and closing movement of the net or sheet, the wire rope to the winch Since the load applied to the wire rope is different between the take-in side and the take-out side (with respect to the drive unit of the winch), slack is likely to occur particularly on the take-out side of the wire rope to the winch. In the present invention, the wire rope can be moved endlessly while eliminating the slack at the winch portion, so that the net or the sheet can be opened and closed smoothly.

The loosening of the wire rope in the winch is achieved by pressing the wire rope between a plurality of guide rings and guide guides provided on the winch , and a pressing body in which tension is provided on both ends on the outer periphery of the winding ring. by moving in a state where tension is applied in the direction of rotation of the winding ring, in order to be able to move the wire rope always state tension is applied, the slack take-out side or inlet side of the winch wire rope Eliminating and moving the wire rope, the net or sheet can be opened and closed in the divided direction or in the opposite direction .

The present invention uses a winch to move each net or sheet divided between a plurality of endless wire ropes according to the opening and closing direction in order to cut wind and ultraviolet rays or to cover the space. Or, in a moving system using a seat winch, the wire rope is clamped by a plurality of guide rings and guide guides provided on the take-out side and the take-in side of the winch , respectively , for slack of the wire rope caused by the net or seat load. At the same time, the wire rope is unscrewed into the winch or taken into the winch by moving in an endless manner with tension applied in the rotational direction with a pressing body provided with tension on both ends on the outer periphery of the winding ring. Move the wire rope and open or close the net or sheet in the divided direction or in the opposite direction And performing.
