Description

The present invention relates to a winch that can reliably wind a rope and move endlessly, and a method for taking in / out a string-like body such as a wire rope using the winch.

For example, as an example of an outdoor facility that uses an endless winch, there is a ball game facility such as baseball or a soccer player, a golf ball or a ball-proof net used in its practice field. The ball for netting is moved by moving a wire rope suspended between pillars with a winch so that the net is moved up and down, opened and closed left and right, or a combination thereof.
In recent years, a UV sheet for cutting off ultraviolet rays has been provided above the outdoor pool, and the UV sheet can be opened and closed by moving the wire rope suspended between the support columns with a winch in the same manner as described above. ing.
In addition, endless winches are used for moving rain / fog / snow nets / seats on construction sites and highways, and for lifting observation balloons and the like.

As an example of an indoor facility that uses an endless winch, in a multipurpose indoor ball game field having a school gymnasium or a large space part, the partitioning net and / or the ball-proofing net of the space part can be moved up and down. Used for opening and closing movement.
The ball-proof net or the partition net is provided indirectly or directly on the wire rope by moving a wire rope suspended from one side wall of the ceiling along the other side wall using a winch. The net attached to the wire rope is moved up and down by moving the opened / closed net or moving the wire rope suspended along the arcuate part of the ceiling using the winch. ing.

The wire rope used outdoors is easily affected by the wind. Especially in facilities where nets / seats are installed, the wind influence is strong and the column may be damaged. Use a winch on windy days. The wire rope must be moved to quickly store the net.

Also, in the indoor facilities described above, the wire rope is moved using a winch and the net is moved up and down to change the partition according to the purpose of indoor use, but the net load is applied to one wire rope near the winch when moving up and down. In order to move the wire rope smoothly with the winch, it is necessary to apply tension to the other wire rope to maintain the whole wire rope in a tensioned state.

As the winch for moving the wire rope, a wind-up winch provided with a take-up reel or an endless winch for moving the wire rope endlessly according to the purpose is used. Since it is necessary to install a number of winches corresponding to the number of wire ropes used, the number of used winches increases and costs increase compared to the case of using endless winches. Many.

As the endless winch, for example, there is a winch disclosed in Japanese Patent Application Laid-Open No. 2000-351580.
This winch is composed of a winch body, a winding drum provided on the winch body for winding and moving the wire rope, and a roller chain for pressing the wire rope against the circumferential surface of the winding drum, and both ends of the roller chain. The side is stretched by an elastic body provided on the winch body.

In the winch, since both ends of the roller chain are stretched by an elastic body provided on the winch body, the roller chain is always pulled in the rotating direction of the winding drum, and the wire rope is attached to the winding drum. The take-in side is pressed, and the take-out side of the wire rope from the winding drum becomes free (no tension is applied). Moreover, since the wire rope can be moved while being pressed against the peripheral surface of the winding drum, there is no loss of force during the movement of the wire rope, and there is no displacement of the wire rope during the movement, thereby enabling an appropriate movement. .

Problems to be solved by the invention

However, since the above conventional endless winch is provided with elastic bodies on both ends of the roller chain, it can move smoothly even in the case of a wire rope that is not tensioned or weakly tensioned. The roller chain may move more than necessary around the outer circumference of the winding drum due to the size of the tension applied or the change in tension, or may not be able to move sufficiently, resulting in insufficient pressing force to the winding drum. If you cannot move smoothly.

In addition, since the configuration in which the elastic body is provided on both ends of the roller chain is complicated, a roller roller having a fixed type is usually used on both ends or one end. In this case, the roller chain is disposed on the circumferential surface of the winding drum. There was a drawback in that the wire rope was heavily worn due to the pressing action only.

Moreover, in the conventional winch, when moving the wire rope to the winding drum side, it is necessary to strengthen the winding of the wire rope around the winding drum by narrowing the space between the guide rollers that guide and move the wire rope. When the gap between the rollers is narrowed, the wire rope taken out from the winch has a refracted wrinkle, which causes wear.

In addition, the conventional winch has a drawback that the roller chain cannot be installed on the winding drum, particularly when the direction of the wire rope winch to the take-in side and the take-out side are different, especially when changing 180 degrees. It was.

In addition, in facilities (such as indoor net moving devices) using winding reels and endless winches that are already installed, the rotation shafts of the endless winch and the winding reel are separate. The movement amount of the wire rope moved by the endless winch and the winding amount of the wire rope moved by the take-up reel are not the same, and the adjustment of the movement amount is complicated and the wire rope cannot be wound smoothly. There is a case.

In particular, when slack or the like occurs in the movement of the wire rope in the winch, there is a serious problem that the movement cannot be performed smoothly and the appropriate wire rope cannot be taken in.

In addition, since the conventional endless winch cannot freely change the direction of the wire rope take-in side and take-out side, the installation position of the take-up reel is limited to a position close to the winch or an integrated position. There was a drawback.

Therefore, the present invention can appropriately convey the rotational drive of the winding drum without being related to slack or the like, such as a wire rope, and can move / take in smoothly, and can be attached to a conventional facility. It is an object of the present invention to provide a winch that can be simplified and a method of taking in / out a string-like body such as a wire rope using a winch that is frequently used.

Means for solving the problem

According to the present invention, a first means of a winch for solving the above-mentioned problems includes: a winding drum for winding a string-like body such as a wire rope; and a drive source for driving the winding drum to rotate forward / reversely. In a winch configured to take in a string-like body such as a wire rope from one side and to take out and move a string-like body such as a wire rope from the other side, at least a part of the outer periphery of the winding drum has a winding drum positive / according to the reverse rotation drive, while the incorporation side to the winding drum of the cord-like body such as the wire rope to rotate or move along the side of the rail or the like to the winding drum direction, or set the winch body By intermittently repeating pressing while rotating / oscillating along the fixed axis, the taking-in is assisted, and the take-out side of the string-like body such as a wire rope from the winding drum is separated from the winding drum. In the direction Rotate or move along the side of a tool, etc., or rotate / oscillate along a fixed shaft provided on the winch body and move to a free position to press on a wire rope or other string-like body It is characterized in that a movement assisting means for releasing is provided.

Means relating to a method of winding a string-like body such as a wire rope using a winch includes a winding drum for winding a string-like body such as a wire rope, and a drive source for driving the winding drum to rotate forward / reversely. After taking a string-like body such as a wire rope from one side and moving a string-like body such as a wire rope from one side to the other using a winch that takes out and moves the string-like body from the other side, In the method for taking in / out a string-like body such as a wire rope using a winch that takes in / out a string-like body such as a wire rope moved to the other side by a take-out means such as a take-up reel. roll along the sides of such rail / using a moving auxiliary means the uptake side of the string-like body such as a wire rope winding drum direction according to the moving direction of the cord-like body such as the wire rope during the reverse rotation drive Is supported by intermittently pressing repeatedly while moving or rotating / swinging along a fixed axis provided on the winch body, and a string-like body such as a wire rope from a winding drum extraction side is rotated or moved along the side of the rail or the like in a direction away from the winding drum, or to rotate / swing movement along a fixed shaft provided on the winch body moves in a free position of After moving in the desired direction with the gap between the take-in and take-out of the wire rope and the like being widened, the moved amount of the wire rope and other cord-like bodies can be freely accommodated in the desired direction. And taking in / out by the taking-out means.

Effects and effects of the invention

In the winch of the present invention, first, a string-like body such as a wire rope is moved to a position in contact with the winding drum, and the winding drum is rotated to drive a string such as a wire rope along the circumferential surface from one side of the winding drum. It moves so as to wind the state body and takes it out from the other side of the winding drum.

At this time, the string-like body such as the wire rope is made of the wire rope or the like by the movement assisting means provided at least in part / near the outer periphery of the winding drum at the time of forward / reverse rotation of the winding drum. By assisting the movement of the wire body while pressing it toward the winding drum side, it is possible to appropriately move the wire rope or other string-like body into the winding drum even if slack / deflection occurs. Thus, the winding drum can be reliably moved without idling as in the prior art.

The specific method of assisting the movement to the string-like body such as the wire rope is to assist the take-in while pressing and moving the take-in side of the wire-like string-like body to the winding drum toward the winding drum, In addition, by moving to a free position while releasing the pressing of the wire rope or other string-like body from the winding drum, the rotation drive of the winding drum is reliably transmitted to the string-like body such as the wire rope, It is possible to reliably take in and take out a string-like body such as a wire rope.

For this reason, for example, even if slack / deflection occurs in a string-like body such as a wire rope, it can be taken into the winding drum, and the winding drum moves reliably without idling as in the prior art. In addition, it is possible to suppress wear of the string-like body such as the wire rope as much as possible by moving in a desired direction in a state where the space between the taking-in and taking-out of the string-like body such as the wire rope is widened .

In a winch in which a pressing moving body is provided on the outer periphery of the winding drum, the rotational drive of the winding drum is transmitted while pressing a string-like body such as a wire rope against a groove on the outer periphery of the winding drum with the pressing moving body. When pressing and moving, at least one end of the pressing moving body is pressed toward the winding drum by the movement assisting means provided on the outside of one end of the pressing moving body (on the side of taking in the string-like body such as a wire rope). However, it indirectly assists the take-in movement of a string-like body such as a wire rope.

Alternatively, when the movement assisting means is provided inside the one end of the pressing moving body, the pressing moving body assists the pressing of the moving assisting means toward the winding drum, and a string such as a wire rope. It directly assists the uptake movement of the body.

As described above, the wire rope or the like on the take-in side of the winding drum is pressed against the winding drum while the string-like body is pressed toward the winding drum, and can move without spinning to the take-out side along the rotation of the winding drum. it can.

Also in this case, by moving to a free position while releasing the pressing to the winding drum side by the pressing moving body on the take-out side of the string-like body such as the wire rope by the movement assisting means in the same manner as described above, the wire rope etc. The string-like body can be appropriately taken out and moved.

As in the above examples, when the movement assisting means of the present invention is used, the rotational driving force of the winding drum can be reliably transmitted to a string-like body such as a wire rope, and a smooth and appropriate wire rope or the like can be transmitted without waste. The string-like body can be moved. For this reason, even if slack / deflection occurs in the string-like body such as a wire rope, the string-like body such as the wire rope can be reliably moved without causing the winding drum to idle as in the prior art. And

In addition, by adjusting the pressing by the pressing moving body corresponding to the winding drum, the rotational driving of the winding drum can be reliably transmitted to a string-like body such as a wire rope, When the string-like body moves from one side to the other, the string-like body such as a wire rope can move smoothly without being idle.

In addition, a method of taking in / out a string-like body such as a wire rope using a winch is wound around a winding drum so that the string-like body such as a wire rope moves from one side to the other, and the winding drum is forward / reverse. By rotating, at least a part or the vicinity of the outer periphery of the winding drum around which the wire rope or the like is wound, any wire rope or the like when the winding drum is driven forward / reversely. Depending on the direction of movement, on the take-in side of a string-like body such as a wire rope, the wire-like body such as a wire rope is pushed and moved toward the winding drum while assisting the take-in, and the take-out side of the wire-like body such as a wire rope Then, while releasing the pressure of the wire rope or the like to the winding drum side , move to the free position and move the wire rope or the like to the desired direction (the direction of taking in and the direction of taking out is the same, different Direction (reverse, After moving in unfolded between the capture and removal of the wire material, such as wire rope in different directions, etc.)) of 0 degree angle, the fatigue bending a string-like body such as a wire rope moving amounts It takes in / draws out by the taking-out means corresponding to a desired direction freely without giving .

In this way, the location of the winch or the location of the take-out means can be set by freely installing the winch or the distance from the winch depending on the method of use of the winch (the direction of movement from one side of the wire rope or other string-like body) can do.

As described above, in the winch of the present invention, since the movement assisting means is provided on the outer periphery / near the winding drum, the tension is not applied even when the string-like body such as the wire rope is tensioned. Similarly, even in a slack / deflection state, it can move smoothly without waste, and a constant amount of wire-like body such as a wire rope can always be accurately moved as compared with conventional winch movement.

In addition, the winch of the present invention has a simple structure, and at least one winding drum can be provided on a single winch on the same axis or on separate axes. In addition, it is possible to reduce the number of winches and reduce the cost as compared with the conventional case.

In addition, the winch of the present invention is installed so as to interlock with a conventional winch (winding winch, endless winch), or the winch winding drum of the present invention is provided on the drive shaft of the conventional winch. Thus, the driving safety of the winch can be remarkably improved, and the existing facility can be used as it is without greatly modifying the existing facility, so that the installation cost can be significantly reduced.

In addition, the method using the winch can surely adjust the pressing force and the amount of movement of the string-like body such as a wire rope to the winding drum with a simple configuration, so that the range of use can be greatly expanded. It becomes possible.

Moreover, since a movement assistance means can also be set freely, the utilization range of the various facilities which use the winch, an apparatus, etc. can be expanded further.

A winch 1 according to the present invention will be described with reference to FIGS. 1 and 14.
A winch 1 according to the present invention is provided in a winch body 1A, and a drive shaft 12 that is rotationally driven (a drive means such as a configuration that is rotated by manual electric power or an assist power source can be freely selected according to the purpose); Generally provided in the drive shaft 12 and having a substantially circular shape with a substantially V-shaped groove 2A formed on the outer peripheral side surface (the case where the groove 2A is formed once is used, When the take-in direction and the take-out direction are different, it is possible to form 1.5 rounds or the like.) The winding drum 2, and the string-like body 7 is taken into the winding drum 2 from one side and the string from the other side. Between the guide rollers 3 and two guide rollers 3 rotatably supported in parallel positions on the take-in side and the take-out side, respectively, in order to assist in taking out the body 7 from the winding drum 2 The winding drum 2 side is It is formed in a par-like shape and guides the route of the string-like body 7 in a state of being sandwiched between the guide drums 3 (formed in a cylindrical shape or a semi-cylindrical shape depending on the type of the string-like body 7, the place of use, etc. Further, the distance to the winding drum 2 side is also changed depending on the type of the string-like body 7, for example, a wire rope is formed with a slightly shorter overall length, and a resin rope is used on the winding drum 2 side. The guide guide 4 is formed adjacent to the winding drum 2, and the movement auxiliary body 6 as movement auxiliary means attached to the take-in side of the string-like body 7 to the winding drum 2 and the take-out side of the string-like body 7. Has been.

In the present invention, the movement assisting means is provided at two locations around the winding drum 2, and has a configuration in which the string-like body 7 is added to the groove 2 </ b> A side of the winding drum 2 and pressed, and the string-like body 7. A structure that moves to a free position while releasing the pressure on the.

As described above, the winch 1 of the present invention clearly describes the characteristics of the winch body 1A, and the drive source (especially when the rotational drive of the winding drum 2 is electrically driven) is variously used in general. Use the drive source. Therefore, the use of an electromagnetic brake or the like for the brake mechanism or the use of a clutch mechanism or the like, or providing an auxiliary brake for safety is also a well-known technique in the field of drive sources. In short, the drive source can be selected according to the size of the winch 1 and the purpose of use.

The string-like body 7 (wire rope / ordinary reinforced rope / linear body provided with vinyl on the outer periphery, etc.) is taken into the winding drum 2 side along the guide guide 4 from one of the guide guides 4 ( The take-up drum 2) is provided along the groove 2A by rotational drive, moves along the rotary drive, and is taken out again from the other along the guide guide 4 (take-out side).

The movement auxiliary body 6 is formed in a flat plate shape or a three-dimensional circular or elliptical shape (the size is determined by the type of the string-like body 7 and the size of the winding drum 2), and the side surface 1B of the winch body 1A. Rotate or move along side surface 1B of the rail or the like along a slide groove 1C (which assists, corrects, or adjusts the movement width swing width) formed in (or as a separate rail). In the case of an oval shape, it is configured to move while swinging or rotating while swinging along the side surface 1B such as a rail. In this case, an elliptical groove 6A may be formed in the center of the movement assisting body 6 so as to rotate / oscillate along a fixed shaft 6B provided on the winch body 1A (see FIG. 2 and FIG. 2). (See FIG. 9).

Therefore, on the side of the string-like body 7 taken into the winch 1, the movement assisting body 6 rotates / swings along the moving direction of the string-like body 7 (direction close to the winding drum 2) while sliding the slide groove 1 </ b> B. The movement and repeated pressing of the string-like body 7 toward the groove 2A side of the winding drum 2 are repeated, and the string-like body 7 is smoothly taken into the groove 2A of the winding drum 2. Then, after moving along the rotation to the winding drum 2, on the take-out side of the string-like body 7, the movement auxiliary body 6 rotates along the moving direction of the string-like body 7 (direction away from the winding drum 2). / While swinging, the slide groove 1B moves in the direction opposite to the intake side (the direction away from the winding drum 2) and moves away from the string 7 and moves to the free position. 7 is smoothly taken out without being pressed to the groove 2A side of the winding drum 2 (see FIGS. 2 to 4).

When the take-out side and the take-in side of the string-like body 7 are interchanged by forward / reverse rotation drive of the drive shaft 12 of the winding drum 2, the movement auxiliary body 6 changes the movement direction in the opposite direction to the above according to the rotation drive. In order to change, the string 7 can be moved freely in either direction with respect to the winding drum 2.

In the above description, the slide groove 1C is provided on the side surface 1B of the winch body 1A in order to assist the movement of the movement auxiliary body 6. However, the configuration of the slide groove 1C as described above is not an essential component. For example, by changing the shape of the movement auxiliary body 6, even if there is no slide groove 1C, the same effect as described above can be obtained. The shape of the movement auxiliary body 6 that is preferable in the experiment is formed in the shape of a water droplet (a structure having three-dimensionality), and is configured to move while swinging using the side surface 1B of the winch body 1A. Worked optimally.

By providing the movement auxiliary body 6 as described above, it is possible to press the take-in side of the string-like body 7 into the winding drum 2 and to release it by releasing the take-out side, so that it is free from the conventional winch. , Between the guide rollers 3 provided on the take-in side and take-out side of the string-like body 7 (conventionally, the distance of C1 (previously, it was necessary to appropriately transmit the rotation of the winding drum 2 by making this distance as narrow as possible). )) Can be expanded to C2. (See FIG. 5) can be expanded, and the string-like body 7 is not subjected to great fatigue bending when moving between the winding drums 2. For this reason, the wear of the string-like body 7 is minimized as much as possible (in the conventional winch, by narrowing the gap between the guide rollers 3, the difference in tension due to the load on the string-like body 7 on the take-in side and the take-out side is eliminated. Since the rotation drive of the rotating drum 2 is configured to be smoothly transmitted, the string-like body 7 is greatly bent at the guide roller 3 portion, and the string-like body 7 is worn at this portion. Therefore, the maintenance work at the basic part such as the frequent replacement of the string-like body 7 and the repair can be omitted as much as possible.

Further, conventionally, in order to give the string-like body 7 a large fatigue bend, the refracted wrinkles often remain on the taken-out string-like body 7, and the string-like body 7 cannot be moved appropriately thereafter. However, in the present invention, since the refracted wrinkles do not remain in the string-like body 7, the subsequent movement and storage can be performed smoothly.

Further, when moving the string-like body 7, the load is applied to the string-like body 7 or the property of the string-like body 7 (in the case of a wire rope, a plurality of thin wires are wound several times to form a linear shape. It moves while rotating a little due to the nature of returning to Therefore, in the conventional winch, the string-like body 7 is pressed against the groove portion of the winding drum and the rotation of the string-like body 7 is suppressed, which causes wear. However, in the case of the winch 1 of the present invention, the movement auxiliary body 6 Therefore, the string-like body 7 moves smoothly without forcibly pressing the rotation of the string-like body 7, and the string-like body 7 moves smoothly. Therefore, it is possible to eliminate the cause of wear of the string-like body 7 as much as possible as compared with the conventional case.

Next, the winch 1 of the present invention is configured as described above, and the following operation will be described.

First, when the distal end side of the string-like body 7 made of a wire rope or a strong resin rope is taken into the winch body along one guide guide 4, the string-like body 7 is moved by the guide guide 4 and the guide roller 3. It is easily moved to the winding drum 2 side in a sandwiched state, and is automatically taken into the guide guide 4 from the tip end side by rotating the drive shaft 12 of the winding drum 2, and the winding drum 2 It moves along the groove 2 </ b> A on the outer peripheral surface, takes out again toward the guide guide 4, and is taken out along the other guide guide 4.

At this time, since the space between the guide rollers 3 is wider than that of the conventional winch, the bending of fatigue at the guide roller 3 portion of the string-like body 7 becomes as small as possible. Move smoothly. Moreover, since the string-like body 7 taken out from the winch 1 does not have a bent wrinkle as in the case of using a conventional winch depending on the type (especially a wire rope), the subsequent movement of the string-like body 7 does not occur. Easy to do.

Further, the movement auxiliary body 6 provided on the take-in side and the take-out side of the string-like body 7 on the winding drum 2 side rotates (in the case of a circle) / swings along the slide groove 1C. Move (in the case of an elliptical shape) to the winding drum 2 side (in the case of the elliptical groove 6A and the fixed shaft 6B, move only the distance of the elliptical groove 6A), and press the string 7 to the winding drum 2 side To do. On the take-out side, the movement auxiliary body 6 moves in a direction away from the winding drum 2 while rotating / swinging along the slide groove 1C, and the pressing of the string-like body 7 toward the winding drum 2 is released. The Accordingly, the string-like body 7 can be easily taken in along the outer circumferential groove 2A on the take-in side of the string-like body 7 and the string-like body 7 on the take-out side is released from being pressed to the string-like body 7. Thus, it can be easily taken out from the groove 2A.

For this reason, even if the string-like body 7 has slack / deflection or the like, the take-in side of the string-like body 7 is pressed against the groove 2A side of the winding drum 2, so that the slack / deflection or the like is reliably eliminated. The string-like body 7 can be taken in, and the take-out side can be taken out in a state where the slack / deflection of the string-like body 7 is eliminated.

Further, since the movement assisting body 6 rotates / oscillates along the slide groove 1C, on the side where the string-like body 7 is taken into the winch 1, the rotation of the string-like body 7 is appropriately assisted and the winding drum 2 is rotated. Since it is taken in and moved into the groove 2A and is not freely rotated / oscillated by pressing the string-like body 7 on the take-out side, the string-like body 7 can be smoothly taken out and moved while being appropriately rotated. In this way, by pressing the appropriate string-like body 7, the cause of wear at the groove 2A portion of the winding drum 2 can be eliminated as much as possible in comparison with the case where the conventional winch groove is taken in.

Moreover, in the said Example, although the movement auxiliary body 6 pressed the taking-in side to the winding drum 2 of the string-like body 7, the effect | action of the movement auxiliary body 6 is not limited to this in this invention, For example, The same effect can be obtained by pressing the take-out side of the string-like body 7.

Next, another embodiment of the winch 1 of the present invention will be described with reference to FIG.

The winch 1 is based on the configuration shown in FIG. 1, and a different configuration is that a roller chain (otherwise connected to the portion where the string-like body 7 is wound along the groove 2 </ b> A on the outer peripheral surface of the winding drum 2 is used. A press moving body 8 composed of a spherical body, a plate spring, a fastening body, and the like. A spring or the like is provided near the guide roller 3 at both ends of the press moving body 8 according to the purpose of use. The elastic body 5 which consists of an elastic body or a weight body is provided.

In the present invention, the press moving body 8 refers to the string-like body 7 wound around the entire portion provided along the groove 2 </ b> A on the outer peripheral surface of the winding drum 2 and moving in the moving direction of the winding drum 2. The string 7 is pressed so as to prevent the string 7 from protruding from the groove 2A.

The pressing movable body 8 moves while pressing the string-like body 7 wound along the groove 2A on the outer peripheral surface of the winding drum 2 in the axial direction, thereby removing the string-like body 7 from the groove 2A. While preventing, it presses, moving the whole along the movement of the string-like body 7 along this groove | channel 2A.

Next, the movement auxiliary body 6 is provided on both end sides of the pressing moving body 8, and the pressing moving body 8 moves while pressing the pressing moving body 8 from the outer side to the winding drum 2 side on the take-in side of the string-like body 7. Accordingly, the winding drum moves by a predetermined amount along the side surface of the winch 1, and on the take-out side of the string-like body 7, the direction to release the pressure on the press-moving body (the direction opposite to the take-in side) Move away from 2.

For this reason, the string-like body 7 can be pressed and moved more strongly to the winding drum 2 side than the winch 1 without the pressing moving body 8, and the take-in side and the take-out side of the winding drum 2 can be moved between the guide rollers 3. Can be extended to a distance parallel to or more than that, and the wear of the string-like body 7 can be further eliminated.

Each of the elastic bodies 5 is fixed to the winch body 1A at one end side and connected to the pressing moving body 8 at the other end side, so that the pressing moving body 8 is always in a state in which elasticity is loaded on both end sides. When the second drive shaft 12 is driven to rotate forward / reversely, the string-like body 7 is pressed and moved to the groove 2A side of the winding drum 2 while moving in the direction corresponding to the rotation direction.

In the above-described embodiment, the elastic body 5 is described as being provided on both ends of the press moving body 8. However, in the present invention, the configuration of the press moving body 8 is not limited to this. 5 is provided only on one side of the press moving body 8 and the other side is fixed to the winch body 1A so that the pressing force and the moving amount of the press moving body 8 can be limited to one direction. In this case, it is necessary to limit the rotation direction of the winding drum 2 to one direction. It is also possible to divide the pressing moving body 8 into a plurality of parts, fix one and provide the elastic body 5 on the other (for example, the pressing moving body 8 is divided into two at the outer peripheral vertex of the winding drum 2 and the divided portion is divided. It is also possible to configure so that the pressing force and the moving amount are adjusted on the take-in side and the take-out side of the string-like body 7 by fixing each to the winch body and providing the elastic body 5 on the other end side. In such a case, a separate pressing plate is provided at the divided portion so as to prevent wear of the string-like body 7 at the divided portion as much as possible, and without providing the elastic body 5 at both ends of the pressing moving body 8, By fixing both end sides to the winch body, it is possible to prevent the pressing moving body 8 from moving along the winding drum 2 and to limit only the pressing force to the groove 2A side. Even in such a case, in the present invention, the movement auxiliary body 6 is provided on the outside thereof. No string-like body 7 only presses the moving body 8 to which must be pressed and moved. Therefore, it is possible to select the optimal configuration of the pressing movable unit 8 in accordance with the intended use of the winch 1.

Further, the elastic body 5 is not limited to the above-described embodiment. For example, the elastic body 5 is provided outside the winch main body via a connecting string-like body 7A such as a wire rope on both ends of the pressing moving body 8. The elastic body 5 can be attached / detached and the load of the elastic force can be freely changed, so that the load on the string-like body 7, the type of the string-like body 7, or the diameter of the string-like body 7 is changed. It is possible to respond by changing the load etc. freely.

Further, without being limited to the elastic body 5, by connecting the weight body to the both end sides of the pressing moving body via the connecting string-like body 7A, the configuration, the mounting method, and the change can be performed easily and smoothly. It is also possible to do. In addition, it is possible to release the load of the pressing moving body 8 by the elastic force by attaching an elastic force switching mechanism 5A such as a clutch mechanism in the middle of the connecting string-like body 7A. It is also possible to attach the middle part of the string-like body 7 to the winding drum 2 in a state where the load of the pressing moving body 8 is released.

Furthermore, if the release of the load by the elastic force is used, for example, a wire rope (or a resin rope that is easily loosened) because the tip is loosened due to high use frequency in a state in which the load of the pressing movable body 8 is released. ) Can be easily moved along the groove 2A of the winding drum 2 without being caught by the pressing moving body 8 in the middle, and a wire rope is attached to the winding drum 2. The wire rope can be appropriately moved by applying a load by an elastic force after winding (see FIGS. 8 and 9).

Further, the load of the elastic force on the pressing moving body 8 is not limited to the above configuration. For example, the pressing moving body 8 itself is configured by an elastic body (for example, in the case of a roller chain, a spring is used between each roller. It is also possible to obtain the same operation and effect as described above by connecting them together or configuring them as a whole with a ring-shaped spring.

The pressing and moving body 8 wound around the outer peripheral side surface of the winding drum 2 rotates the winding drum 2 so that a desired force is generated along the groove 2A of the winding drum 2 on the take-in side of the string-like body 7. Thus, the pressing force is released on the take-out side of the string-like body 7, so that the string-like body 7 can be smoothly moved from the take-in side to the take-out side without slack.

In this way, the pressing moving body 8 moves in a state where the take-up side is pulled toward the winding drum 2 along the rotation of the winding drum 2 by the elastic bodies 5 at both ends, and the take-out side is separated from the winding drum 2. Then, it is moved (pressed while moving) so as to be pulled in a direction not pressed.

Next, the pressing position on the string-like body 7 by the pressing moving body 8 is further assisted by the movement assisting body 6 and the pushing movement (the pressing side of the pressing moving body 8 on the intake side of the string-like body 7 to the winding drum 2) is performed. In addition, the string-like body 7 is indirectly moved more accurately by moving in a pressed manner in conjunction with the movement and moving away from the winding drum 2 so that the pressure is released in the same manner. The rotation of the winding drum 2 can be reliably transmitted to the string-like body 7 without waste.

In the winch 1 in the case where the pressing moving body 8 is not provided, the position where the movement auxiliary body 6 is provided is provided on the take-in side of the string-like body 7 to the winding drum 2 and on the take-out side of the string-like body 7, respectively. In the present invention, the position where the movement auxiliary body 6 is provided is not limited to this. For example, a plurality of movement auxiliary bodies 6 are provided around the winding drum 2 (a certain frame 36 (at both end sides along the outer periphery of the winding drum 2). A plurality of stoppers are provided), and a roller 35 is provided in the frame 36 so that a desired distance roller 35 can be moved along the frame 36) (FIG. 11). (See FIG. 10), or the winding drum 2 can be provided directly on the case of the winch 1 (with a roller 35 or a leaf spring attached thereto). Ingest / extract It is also possible to provide a guide body 37, and to provide a movement auxiliary body 6 composed of rollers in the frame at the zenith (see FIG. 12), and the string-like body 7 of the winding drum 2 It is also possible to press the string-like body 7 further toward the groove 2A side of the winding drum 2 by providing the movement auxiliary bodies 6 (6a, 6b, 6c) at three places on the taking-in side, taking-out side, and zenith. Yes (see Fig. 12-A)

Further, in the winch 1 having the pressing moving body 8, the movement assisting means is not limited to the moving assisting body 6. For example, the moving assisting body 6 is in close contact with one end side of the pressing moving body 8. By providing the string-like body 7, the string-like body 7 can be directly taken in and moved while the auxiliary moving body 6 is pressed against the winding drum 2 by the pressing moving body 8 on the take-in side of the string-like body 7. Or in the case where the movement auxiliary body 6 is provided outside the one end side of the pressing moving body 8 as in the embodiment, it is possible to press the winding drum 2 side much stronger (FIG. 12-). B).
Further, as another means, for example, a movement assisting means is erected to prevent the movement of the elastic body 5 in the vicinity of the elastic body 5 and the winding drum 2 at the position where the elastic body 5 extends and moves to the winding drum 2 side. By using the movement auxiliary body 6 configured to have the plate-like stopper function (see FIG. 13), the movement of the pressing moving body 8 is prevented and the movement amount and the pressing force of the pressing moving body 8 are adjusted. It is also possible.
Further, for example, the movement assisting means is connected to the guide drum 3 as a movement assisting body 6 formed as a support shaft in one end example of the elastic body 5, and the guide drum 3 is connected to the guide drum 3 via a clutch mechanism. By providing a reverse stopper (not shown) that can rotate only in the direction (see FIG. 14), it is also possible to block the movement amount and the pressing force of the pressing moving body 8 at a fixed position. is there. In this case, when the string-like body 7 is moved in one direction, the guide drum 3 can be rotated in one direction. Therefore, the pressing moving body 8 can be pressed and moved in the same direction while the elastic body 5 is pulled. .

That is, the shape, configuration, and attachment position of the movement assisting body 6 are appropriately changed depending on the use state of the winch 1, the usage method, the type and diameter of the moving string 7, the load applied to the string 7, and the like. Can do.

Further, the shape of the groove 2a of the winding drum 2 is not limited to a substantially V shape, and can be a substantially C shape, a substantially U shape, a substantially O shape, a groove having a width of two steps, or the like. It can correspond to the shape, and even when there is the pressing moving body 8 or when there is no pressing moving body 8, the rotational drive of the winding drum 2 can be reliably transmitted to the string-like body 7 without waste.

Next, the case where the capstan 19 is attached to the winch 1 of the present invention (see FIGS. 15 and 16) will be described.

When the capstan 19 is used for the winding movement of the string-like body 7 in the conventional net / sheet moving system, the capstan 19 is directly attached to the outer peripheral side surface of the winding drum 2 of the winch 1 (or the capstan The string 7 is wound around the outer periphery of the capstan 19 a plurality of times, and both end sides thereof are taken out from the winch 1.

At this time, a wide pressing moving body 8 and a movement auxiliary body 6 are provided on the outer periphery of the capstan 19, so that the string-like body 7 wound around the capstan 19 is pressed by the pressing moving body 8 and the capstan 19. In addition to suppressing the protrusion of the string-like body 7 and pressing the take-in side of the string-like body 7 into the capstan 19 with the movement assisting body 6, the string-like body 7 can be moved smoothly. Or only the movement auxiliary body 6 is provided, and the string-like body 7 can be moved smoothly by pressing the take-in side of the string-like body 7 into the capstan 19.

It is also possible to connect and use another conventional winch 30 and the winch 1 provided with the capstan 19.

Next, a method (system) (see FIGS. 17 and 19) for directly connecting to the drive shaft 31 of the conventional winch 30 using the winch 1 of the present invention will be described.

The drive shaft 31 of the winch 30 is inserted and attached to the drive shaft 12 portion of the winding drum 2 of the winch 1 provided with the movement assisting body 6 and the pressing moving body 8 as described above, so that the winch 30 is rotationally driven. Directly transmitted to the winding drum 2.
At this time, when the cross section of the drive shaft 31 is formed in a rectangular shape (the drawing is a square shape but may be a polygonal shape), the shape of the drive shaft 12 portion of the winding drum 2 is formed to be the same. By doing so, it can also be easily attached. Also in this case, as in the case of each of the above embodiments, the tension of the string-like body 7 is insufficient by pressing the take-in side of the string-like body 7 into the winding drum 2 with at least the movement auxiliary body 6. Even so, the string-like body 7 can be moved smoothly.

It is also possible to attach a pulley (or gear) to the drive shaft 31 of the winch 30 and connect the drive shaft 31 via a rotating belt.

Next, a method (system) for utilizing (assisting) a conventional winch using the winch 1 of the present invention will be described.

First, a pulley (not shown) different from the winding drum 2 is attached to the rotating shaft 12 of the winch 1, and the pulley and a conventional winch 30 (which may be a winding winch or an endless winch) are attached to the driving shaft 31. By connecting the pulley (or gear) via a belt, the rotating shaft 12 of the winch 1 is rotated using the driving force of the winch 30.

Thereby, by moving the conventional string-like body 7 with the winch 1, it becomes possible to install using the conventional winch 30 as it is. At this time, similarly to the above, on the side where the string-like body 7 is taken into the winding drum 2, the groove is formed by the rotation of the winding drum 2 while being pressed against the groove 2A of the winding drum 2 by the pressing moving body 8. In addition to moving to the take-out side along 2A and moving to the end of the take-in side of the press moving body 8 or the vicinity thereof by being accurately pressed by the movement auxiliary body 6, the string-like body 7 has been eliminated. Captured in state. Further, on the side where the string-like body 7 is removed from the winding drum 2, the pressing by the pressing moving body 8 and the movement assisting body 6 is released, so that the string-like body 7 is smoother than the groove 2 </ b> A of the winding drum 2. It can be taken out.

In the case of the winch 1, the equipment is used as it is by using the driving force of the winch 30 installed in the past, but the drive source of the rotary shaft 31 of the winch 30 installed in the conventional manner is reversed. The drive source can be reused by being connected to the drive shaft 2A of the winch 1 of the present invention.

Note that the conventional method (system) of attaching the pulley to the rotating shaft 31 of the winch 30 can be provided outside the rotating shaft 31 of the conventional winch 30 or in the middle of the rotating shaft 31. When attached to the outer side of the rotary shaft 31, it is possible to wind up the string-like body 7 using the rotary shaft 31, and when attached to the middle part, it is used for moving the endless string-like body 7. There are advantages that can be made.

Further, as another method of use, the winding drum 2 is divided into two vertically by the rotating shaft, so that the moving auxiliary body 6 and the pressing movement are directly applied to the drive shaft (rotating shaft) of the winch that has been conventionally installed. The winding drum 2 provided with the body 8 can be attached, and the conventional work apparatus can be attached without simplifying the attaching work process. Further, the winding drum 2 and the drive shaft 12 can be freely attached and detached, and can be replaced with another winding drum 2 having a different diameter.

Further, there is a slack on the side where the string-like body 7 is taken into the take-up drum (not shown), which is generated when the string-like body 7 is not loaded with tension or when the load due to the tension varies greatly. However, the slack of the string-like body 7 can be eliminated by the action of the pressing moving body 8 and the movement auxiliary body 6 (or the action of the movement auxiliary body 6), and the string-like body 7 can be smoothly wound and moved. .

In this case, the entire outer peripheral side surface of the take-up drum (not shown) is pressed and moved by forming the press moving body 8 wide, but the press mover 8 is divided into a plurality of roll-up drums. It is also possible to locate the entire outer peripheral side surface (not shown), and it is also possible to provide two (a plurality of) pressing moving bodies 8. In this case, the string-like body 7 can be smoothly moved by pressing and moving the string-like body 7 on the take-in side and the string-like body 7 on the take-out side to the take-up drum (not shown). The press moving body 8 is separately attached to the outer periphery of each take-up drum (not shown), but may be configured as a single press moving body 8 by coexisting the tension means 5 at the end. Is possible.

Next, a description will be given of a method (see FIGS. 20 to 22) in a case where the winding reel 11 as an example as a take-out means is attached to the winch 1 of the present invention.

First, the winch 1 of the present invention is installed in the middle part of the string-like body 7 used for various purposes and moved from one side to the other side where the object is provided, and then the other side of the string-like body 7 A take-up reel 11 is installed on the side. At this time, the installation position of the winch 1 and the installation of the take-up reel 11 may be close to each other or separated from each other, and the direction may be vertical or horizontal. It can be installed.
That is, since the winding drum 2 of the winch 1 of the present invention is provided with the movement auxiliary body 6, the string-like body 7 moving from one side to the other is the movement auxiliary body 6 on the take-in side of the string-like body 7. Since it is pressed accurately and the pressing by the movement auxiliary body 6 is released on the take-out side of the string-like body 7, it can move without worrying about the slack / deflection of the string-like body 7. In addition, the movement auxiliary body 6 can freely change the direction of taking in and taking out the string-like body 7.

In addition, with the above configuration, the take-up reel 11 is installed at the position / direction that is most suitable for handling (for example, the winch 1 is installed at a position higher than the ground, and the take-up reel 11 is installed on the ground side). can do. That is, when the take-up reel 11 is attached at a position separated from the winch 1, or can be attached above / below the winch 1, the winch 1 can be installed even when the winch 1 is handled in a dangerous place. The take-up reel 11 can be attached to a safe position away from the position so that the string-like body 7 can be easily moved from one to the other. It is possible to attach the take-up reel 11 to a low position on the floor side, and to pursue safety and ease of work when performing maintenance work.

Further, by attaching the winch 1 and the take-up reel 11 to a base (not shown) so as to be rotatable, the moving direction of the string-like body 7 can be freely finely adjusted. Even if the balloon is lifted or lowered for aerial observation at a dangerous place, even if the movement direction of the string 7 changes due to the influence of wind or the like, the winch 1 and the take-up reel 11 are rotated, so that the string-like body 7 can be easily taken up / drawn out. In addition, even if the string-like body 7 is slack / deflection when the string-like body 7 is wound / drawn, the movement assisting body 6 and / or the pressing moving body 8 is provided on the winding drum 2. Even if such tension is applied, the string-like body 7 can be moved smoothly, and the string-like body 7 can be appropriately wound / drawn out.

In particular, when used in an indoor facility, the installation location of the winch 1 and the take-up reel 11 can be freely changed, so that the string-like body 7 to which the net provided on the ceiling side is attached is used. The winch wire is configured to move between the winch 1 installed on the ceiling side and the take-up reel 11 installed on the floor side, so that maintenance work of the take-up reel 11 where trouble occurs frequently is performed safely and easily. be able to. Accordingly, it is possible to suspend and partition the net freely according to the purpose of use.

Further, another embodiment (see FIGS. 23 and 24) in which the take-up reel 11 is attached to the winch 1 of the present invention will be described.

First, a drive shaft 12 (pulley provided on the drive shaft 12) for rotationally driving the winding drum 2 of the winch 1 of the present invention and a rotary shaft of a take-up reel 11 (a ring intended to wind the string-like body 7). 13 (pulley provided on the rotary shaft 13) is connected via a belt 14. The take-up reel 11 is positioned on the rear upper side of the winch 1 by a support 15 so as to be movable up and down.

In this state, when the drive shaft 12 of the winch 1 is driven, the winding drum 2 rotates, and the string-like body 7 wound around the winding drum 2 is taken in from one side and taken out to the other side. The string-like body 7 taken out from the winch 1 is taken up by the take-up reel 11 provided on the rotary shaft 13 rotating in synchronization with the rotary shaft 13.

At this time, if the moving amount of the string-like body 7 by the winding drum 2 and the winding amount of the winding reel 11 are different, the winding reel 11 supported by the support 15 is moved up and down (the winding drum 2). When the amount of movement of the string-like body 7 is larger than the amount of winding of the take-up reel 11, the take-up reel 11 is moved upward to adjust the amount, and the amount of the string-like body 7 by the winding drum 2 is adjusted. When the amount of movement is smaller than the amount of winding of the winding reel 11, the amount of movement by the winding drum 2 is adjusted by adjusting the amount of difference while moving the winding reel 11 downward and adjusting the amount). Is securely wound around the winding reel 11.

When the string-like body 7 is moved by the winding drum 2, the pressing moving body 8 is moved along the outer periphery of the winding drum 2 by the rotational driving of the winding drum 2, and the take-in side of the pressing moving body 8 is moved. It is pressed accurately by the movement auxiliary body 6 and the string-like body 7 is taken into the groove 2 </ b> A of the winding drum 2 without slack, and then the pressing moving body 8 is pressed and the movement auxiliary body 6 is pressed on the take-out side of the string-like body 7. Each of the presses can be released and the string-like body 7 can be smoothly taken out, and the string-like body 7 moves without spinning when the winding drum 2 is driven to rotate.

As described above, since the rotary shaft 13 of the take-up reel 11 is rotated in synchronism using the driving force of the drive shaft 12 of the winding drum 2, it is compared with the case where the rotary shaft 13 is rotated by different drive shafts. It is easy to adjust the movement amount of the string-like body 7 by the winding drum 2 and the winding amount of the winding reel 11. In addition, since the configuration is simple, the cost can be reduced.

In the above system, the drive shaft 12 of the winch 1 and the rotary shaft 13 of the take-up reel 11 are connected via the belt 14, but the drive transmission means is not limited to this system, and for example, a plurality of It is also possible to transmit via a gear, and by forming the drive shaft 12 in an elongated shape, the take-up reel 11 is directly attached to the extended drive shaft 12, so that A similar effect can be obtained. Furthermore, the same effect can be obtained by using the spring type take-up reel 11.

In the above embodiment, the take-up reel 11 is used as the take-out means. However, the take-out means is not limited to the take-up reel 11 in the present invention. Depending on the type, it may be simply stored in a storage box, or other means are possible.

Further, the string-like body 7 wound around the winding drum 2 of the winch 1 can be obtained by changing the mounting position of the guide roller 3 or increasing the number when the groove 2A of the winding drum 2 is single. 7 can be freely installed and taken out, and the groove 2A of the winding drum 2 is formed continuously so that the taking-in direction and the taking-out direction of the string-like body 7 are changed. Is also possible.

In addition, by manufacturing the moving auxiliary body 6, the pressing moving body 8, the guide roller 3, and the guide guide 4 of the winch 1 of the present invention as separate bodies, the conventional winch 30 used in each system similar to the above is used. It is also possible to easily attach the above-mentioned pressing moving body 8 guide drum 3 and guide guide 4 to the winding drum and use them so as to obtain the same operation and effect as the winch 1 of the present invention.

The attachment of the winch 1 has moved the string-like body 7 endlessly. However, for example, it is also possible to configure the string-like body 7 to be moved by using a take-up type take-up reel 11. . In this case, the rotational drive of the conventional winch 30 is connected to the rotary shaft 12 of the winch 1 of the present invention via the belt 14, the take-up reel 11 is provided near the lower end side of the winch 1, and the rotary shaft 12 and the winding shaft are wound. By connecting the rotary shaft 13 of the take-up reel 11 via the belt 14A, the string-like body 7 connected to the net / sheet 18 is rotated by using the drive of the winch 30 to rotate the winch 1 of the present invention. It is also possible to configure the winding string 11 to be surely wound by the winding reel 11 by rotating the winding reel 11 and moving the string 7.

As shown in each of the above embodiments, the winch 1 of the present invention enables the movement of the string-like body 7 more reliably using the movement auxiliary body 6 and is used for winding the string-like body 7. It can be used for various systems.

Moreover, in the facility where the conventional winch 30 is used, the winch function of the present invention can be assisted by connecting the winch 1 of the present invention to the conventional winch 30, and the use can be remarkably improved.

A great advantage of the winch and each system using the winch according to the present invention is that the string-like body 7 can be reliably moved even in a state where no tension is applied, so that work efficiency including maintenance can be improved.

Further, since the guide rollers 3 and 3 can be freely adjusted according to the type of the string-like body 7, for example, when the string-like body 7 is a wire rope, the guide rollers 3 and 3 are separated from each other. By widening, the wire rope can be moved by the winding drum 2 without bending it greatly, the fatigue wear can be minimized and the replacement of the wire rope can be minimized. The problem can be solved.

Further, even if the string-like body 7 is moved from one direction to the other direction by the winding drum 2, no wrinkles such as bending remain in the string-like body 7, so that the subsequent winding / housing can be easily performed. .

Further, since the string-like body 7 on the intake side is pressed toward the winding drum 2 by the movement auxiliary body 6, the string-like body 7 can be reliably wound around the winding drum 2. Moreover, according to the kind of string-like body 7, the shape of the movement auxiliary body 6, a movement distance movement method, etc. can be set freely.

Further, since the movement auxiliary body 6 also serves as a guide roller used conventionally on the side where the string-like body 7 is taken into the winding drum 2, the side where the string-like body 7 is taken into the winding drum 2. Since the width between the take-out side and the take-out side can be increased to a position approaching the diameter of the winding drum 2, it is not necessary to reduce the width between the take-in side and the take-out side as much as possible to apply tension to the string-like body 7 as in the prior art. In addition, the movement of the string-like body 7 and the rotational driving of the winding drum 2 can be performed smoothly.
