Description

The present invention relates to a winch capable of moving a string-like body such as a plurality of wire ropes endlessly at the same time, and a moving system using the winch.

For example, a net used for ballproofing in an outdoor facility such as a driving range is a wire rope for a guide between a plurality of endless winches installed in accordance with the size of the space and a support column forming the space. A plurality of nets suspended along the top and bottom of each column, and a driving wire rope suspended via a pulley between the upper and lower sides of each column. By driving each winch, the drive shaft is driven to rotate. Rotate the drum once. Then, the driving wire rope wound in the groove formed on the outer peripheral edge of the winding drum is moved endlessly between the pulleys, and a net having one end connected to the driving wire rope is used as a guide wire rope. Move up and down along.

In addition, nets used for ballproofing and partitioning in indoor facilities such as indoor practice fields have a large area in order to accommodate large spaces. Used for partitioning. When opening and closing each of the nets, a plurality of suspension wire ropes are connected to the upper end side of the net, and the suspension wire ropes are moved up and down using a plurality of winches, or the same as described above. By moving a plurality of nets suspended along a wire rope, endlessly between a plurality of drive wire ropes driven by a plurality of winches, and moving the net along a guide wire rope A system that opens and closes is adopted.

In addition, other facilities are used to open / close UV sheets (sheets divided into multiple parts) to cut ultraviolet rays over the large pool of leisure facilities, and to prevent rain / safety at construction sites such as high-rise buildings. There are nets and sheets for anti-fogging / snow protection on highways, as well as up and down movement of countermeasure nets and sheets.

As described above, a mobile system using a winch can be roughly divided into an indoor system and an outdoor system.

For indoor use, install a winch using the ceiling or the upper part of the periphery and attach a ball-proof net to surround the space according to the purpose of use, or attach a partitioning net to open / close and move up and down When used outdoors, it is necessary to store the net quickly on a windy day because it is susceptible to the influence of nature, especially the wind. A system that quickly opens and closes a net that opens and closes by attaching a ball net is used.

The winch used indoors and outdoors is composed of a winch body having a rectangular shape as a whole and a drive unit (in the case of an electric type) made of a motor attached to the winch body via a drive shaft, and the drive shaft Is attached with a winding drum that moves by winding the wire rope around a groove formed on the outer periphery, and presses the wire rope toward the groove along the range where the wire rope is wound around the outer periphery of the winding drum A roller chain that moves is provided, and both ends of the roller chain are stretched by an elastic body provided on the winch body (see JP 2000-351580 A).

Due to the above configuration, the conventional winch is in a state where the roller chain is always pulled in the direction of rotation of the winding drum, the take-in side of the wire rope to the winding drum is pressed, and the take-out side of the wire rope from the winding drum is free Therefore, the force during the movement of the wire rope can be appropriately moved without loss. For this reason, in each said facility etc., the said several winch was synchronized via the control panel, and the large area net | network and several net | networks were moved to opening and closing.

However, since the winch conventionally used moves one wire rope with one winding drum, in a system that moves a plurality of nets with a wire rope, a plurality of winches are synchronized. However, when the number of winches increases, the movement distances of the wire ropes that move with each winch are different, so the wire ropes tend to be loosened and bent, and each winch is driven synchronously. It is difficult to do.

Further, in order to use the space widely, a plurality of winches are required. However, depending on the facility, the installation space for the winch is not sufficient, and all the winches cannot be properly installed.

Therefore, by providing two or more winding drums in the main body of the winch, it is possible to move a plurality of wire ropes simultaneously with one winch, so that each winch can be easily synchronized, and the installation space is reduced. It was considered to solve each of the above problems with less.

Problems to be solved by the invention

However, in the winch provided with the two or more winding drums, if the load applied to the wire rope wound around each winding drum is different, the wire rope is slackened or bent, and each wire rope is smoothly moved. There was a drawback of being unable to move.

Even when one wire rope is wound between each winding drum, the wire rope is slackened or bent depending on the width of the groove of the winding drum and the like because it is wound around the winding drum a plurality of times. There was a drawback that each wire rope could not be moved smoothly.

In addition, there is a drawback in that the winding on each winding drum cannot be sufficiently performed due to the difference in load applied to each wire rope.

Therefore, the present invention simplifies the entire drive system by moving a plurality of wire ropes and other string-like bodies with a single winch, making it easy to adjust the wire rope and other string-like bodies for safety. It is an object of the present invention to provide a fast winch and a moving system using the winch.

Means for solving the problem

According to the present invention, the first means of the winch for solving the above-mentioned problem is a winding drum for winding a string-like body such as a wire rope around a groove formed on the outer periphery thereof as described in claim 1. And a winch main body provided with a drive shaft for driving the winding drum to rotate forward or backward, and by rotating and driving the winding drum, a string-like body such as a wire rope is taken in and moved out. In a moving endless winch, the winch body is provided with at least two or more drive shafts, each drive shaft is provided with a winding drum having the same or different diameter, and one or more of each winding drum is provided. In order to assist the movement of taking in and out of the wire rope or the like wound around the groove of the wire or the movement between the winding drums, the wire rope or the like is cut off in conjunction with the rotation of each winding drum. While pressed against the pressing guide means for guiding the movement of the string-like member such as wire rope, characterized in that provided one or a plurality.

According to the present invention, a first solving means of a moving system using a winch for solving the above-described problems is that, as described in claim 2, the winding drum is rotated forward using a drive shaft provided in the winch body. Alternatively, a winch that opens / closes / lifts a suspended body such as a net using an endless winch that takes in and moves a string-like body such as a wire rope to the winding drum side by reverse rotation driving. In the moving system, the winding drums of the same or different diameters respectively provided on at least two drive shafts provided on the winch body are simultaneously driven to rotate respectively in one or a plurality of grooves of each winding drum. Guide the movement according to the direction of movement while intermittently pressing a plurality of turned wire ropes or the like to the groove side, and simultaneously Wherein the opening and closing / lifting movement depending on the hanging-clad shape Tsuhari body such as a plurality of nets by the string-like body uptake moving and unloading movement and the like.

According to the second aspect of the present invention, there is provided a moving system using a winch for solving the above-mentioned problems. Alternatively, a winch that opens / closes / lifts a suspended body such as a net using an endless winch that takes in and moves a string-like body such as a wire rope to the winding drum side by reverse rotation driving. In the moving system, the winding drums of the same or different diameters respectively provided on at least two drive shafts provided on the winch body are simultaneously driven to rotate respectively in one or a plurality of grooves of each winding drum. A string-like body such as a wire rope that guides its movement in accordance with its moving direction while intermittently pressing the turned wire-like rope-like body toward the groove side. Characterized in that each winding drum between in opening and closing / elevator moves Tsuhari body such as a plurality of nets by extraction movement from the other capture moving the winding drum than the one of the winding drum to drive the movement.

Effects and effects of the invention

The winch according to the first means of the present invention is firstly connected to a net and has at least two or more winding drums provided on the winch body with a string-like body such as a plurality of wire ropes suspended endlessly between pulleys. Are wound around one or a plurality of grooves formed on the outer periphery. In this state, a plurality of wire-like members such as wire ropes are wound around separate winding drums, and the rotation of the winding drums is transmitted separately.

Thereafter, each drive shaft provided in the winch body is rotated in the forward direction to rotate in synchronization with each of the two or more winding drums, so that the string-like body such as a wire rope is rotated along with the rotation of the winding drum. As a result, the suspended body such as a net connected to the string-shaped body such as the wire rope is suspended and moved in a desired direction (horizontal direction or elevating direction).

At this time, because the winch body is provided with a pressing guide means, the wire rope or the like wound around the groove of each winding drum is intermittently moved toward the winding drum while being interlocked with each other. While pressing, the wire-like bodies such as the wire ropes are moved along the guides, and the wire-like bodies such as the wire ropes are smoothly taken in and moved from one side of each winding drum and from the other side of each winding drum. Take out and move.

Next, each drive shaft provided in the winch body is rotated in the opposite direction to the above, so that two or more winding drums are rotated in reverse in synchronization with each other to wind a string-like body such as a wire rope. By moving in the opposite direction to the above along with the rotation of the drum, the connected nets are accommodated and moved in the horizontal direction or the up-and-down direction.

Also in this case, the wire guides are intermittently pressed to the winding drum side while interlocking the wire ropes and the like wound around the grooves of the winding drums by the pressing guide means in the same manner as described above. The cords such as wire ropes are smoothly moved along the guides to smoothly take in and move the cords such as the wire ropes from the other side of the winding drums and move out from the other side of the winding drums to the one side.

Further, when driving the drive shafts, if the winding drums provided on the respective drive shafts have the same size (diameter), the same string-like body such as a wire rope wound around each winding drum is used. When only the distance can be moved and the size (diameter) of each winding drum is different, the winding drum corresponding to the different moving distance is selected, and the string-like body such as the different distance wire rope is moved. can do.

In addition, the adjustment of the load and the like due to the difference in the moving distance of the string-like bodies such as the wire ropes can be smoothly performed by the pressing guide means, so that the diameter of the winding drum can be easily adjusted.

For this reason, even if it is one winch, the same effect as the number of winches according to the number of drive shafts provided in the winch body can be obtained.

Moreover, even if the moving directions of the string-like bodies such as the wire ropes are different from each other, it is possible to deal with them freely by changing the mounting position of the pressing guide means to the winch body. Even if there is a restriction on the position of the winch in the facility, etc., it can be handled freely.

Therefore, in maintenance, the number of winches to be inspected / replaced is small, and the slack / deflection due to the use of string-like bodies such as wire ropes can be easily handled by replacing the winding drum. This is much smoother.

In addition, by winding a single wire rope or other string-like body around two or more winding drums provided in the winch body, the single wire rope or other string-like body can be moved by the winch as in the conventional case. it can. At this time, by rotating each winding drum synchronously, the string rope such as a wire rope can be smoothly moved with a strong rotational driving force as compared with the case where the string rope such as a wire rope is moved by one winding drum. Can be taken in and taken out.

For this reason, the winding drum cannot respond to the load of the string-like body such as the wire rope as in the conventional case, and can move reliably without idling, and the wear of the string-like body such as the wire rope is suppressed as much as possible. be able to.

Thus, since the winch of this invention can move a string-like body, such as a several wire rope, at the same time, the number of winches to be installed can be reduced and the cost can be reduced.

Therefore, since a string-like body such as a plurality of wire ropes can be moved with a simple configuration, a winch can be installed in a small space.

In addition, since the winding drum can be attached to and detached from the drive shaft, it can be installed and used with an appropriate size (diameter) winding drum, so it should be installed and used for all types of facilities and equipment. Can do.

Further, even when the take-in side and the take-out side of a string-like body such as a wire rope to each winding drum are different, they can be freely wound around each winding drum.

In addition, at least one winding drum of the same or different diameter provided on the drive shaft is simultaneously rotated and driven, and a plurality of wire ropes and other string-like bodies are simultaneously moved in the same direction or different directions. Then, a suspended body such as a net can be moved left and right / up and down.

Hereinafter, an embodiment of a winch of the present invention and a moving system using the winch will be described with reference to the following drawings.

It is explanatory drawing.

A winch 1 according to the present invention includes a winch body 2 having a substantially rectangular box shape, and a drive unit (not shown, a handle for manual operation, a motor for electric operation, etc.) connected to the winch main body 2. Yes.

The winch body 2 has two drive shafts 3 (3A, 3B) that are rotatably provided at a desired interval, and a cross-sectional view on the outer peripheral side surface attached to each of the drive shafts 3 (3A, 3B). Two substantially circular winding drums 5 (5A, 5B) having a V-shaped groove and having the same diameter, and a pressure guide detachably fixed in the vicinity of each winding drum 5 (5A, 5B) A pressing guide body 6 is provided as means.

Each winding drum 5 (5A, 5B) has a string-like body 7 along the groove 4 (hereinafter, the string-like body 7 is a wire rope, a normal reinforcing rope, a linear body provided with vinyl on the outer periphery, and (It is described as a general term for recently developed strong resin ropes or the like).

The pressing guide body 6 is attached to the substantially central portion of the winch main body 2 between the winding drums 5 (5A, 5B), and each winding drum 5 (5A, 5A, 5B, 5B, 5B) is elastically (not shown). 5B) a plate-like mounting plate 10 pressed to the side, and three roller bodies 8 (8A, 8B, 8C) rotatably attached to the mounting plate 10, and each roller body 8 is While guiding the one string-like body 7 wound around the groove of the winding drum 5 (5A, 5B) according to the rotation direction of the winding drum 5 (5A, 5B) while swinging by the elastic body. The pressure is released while the other string-like body 7 is guided and moved.

The basic configuration of the winch 1 of the present invention is configured as described above. Next, the case where the two string-like bodies 7 are moved simultaneously using the winch 1 having the above basic configuration will be described.

First, in the case of two string-like bodies 7 that are suspended and moved in the same direction, each string-like body 7 is separately taken into the winding drum 5 (5A, 5B) side, and then each drive shaft 3 (3A). , 3B), the string-like body 7 is wound along the grooves of the respective winding drums 5 (5A, 5B), and the string-like body 7 is taken out and moved in the same direction as the taking-in direction.

At this time, the winding drum 5 (5A, 5B) in which the two string-like bodies 7 are separately wound along the groove is different in the drive shaft 3 (3A, 3B). The effect that two string-like bodies 7 can be moved synchronously as in the case of using a winch can be obtained.

Further, the two string-like bodies 7 wound in the grooves of the winding drum 5 (5A, 5B) are swung while the mounting plate 10 of one pressing guide body 6 is pressed, so that the mounting plate 10 The two roller bodies 8 of the three roller bodies 8 (8A, 8B, 8C) provided on the side are pressed while guiding one string-like body 7 in the taking-in direction and the other string in the taking-out direction. The pressure is released while guiding the body 7.

Thereby, two string-like bodies 7 can be taken in and taken out at the same time, smooth movement becomes possible, and synchronization of the winding drum 5 (5A, 5B) becomes easy.

Next, the movement system of the winch 1 using the movement of the string-like body 7 using the winch 1 having the above basic configuration will be described.

The movement system of the winch 1 of this configuration is mainly used in an indoor space, and the feature of the configuration is the groove of the winding drum 5 (5A, 5B) of one winch 1 installed on the floor side. Two string-like bodies 7 that are wound and respectively taken out from the ceiling side and suspended endlessly between the pulleys 12 along the inclination of the ceiling, and a plurality of suspensions having one end connected to the string-like body 7 The rope 13 and the net 11 connected to the other end of the suspension rope 13 are configured.

When the net 11 is suspended, when the drive shaft 3 (3A, 3B) of the winch 1 is rotated in the forward direction by a drive source, the winding drum 5 (5A, 5B) is also rotated in the forward direction. The net 11 is suspended in the space by moving the string 7 between the pulleys 12 and moving the suspension rope 13 up and down.

Next, when the net 11 is stored, if the drive shaft 3 (3A, 3B) of the winch 1 is driven to rotate in the opposite direction, the winding drums 5 (5A, 5B) are also rotated in the opposite direction, respectively. The string-like body 7 is moved between the pulleys 12, the suspension rope 13 is lowered, the net 11 is moved to the floor surface side, and the net 11 is removed from the suspension rope 13 so that only the net 11 is removed. Store.

In the above embodiment, the movement direction of the two string-like bodies 7 is described as the same direction. However, in the present invention, even when the movement directions of the two string-like bodies 7 are different, it can be handled. it can. For example, the net 11 is moved up and down in the same manner as described above by installing the winch 1 on the ceiling side and taking out the two string-like bodies 7 wound around the winding drum 5 (5A, 5B) in the left-right direction. be able to. In this case, by attaching one pressing guide body 6 between the winding drums 5 (5A, 5B), the guide moves while simultaneously pressing the two string-like bodies 7 with the one pressing guide body 6 as described above. can do.

Next, the movement system of the winch 1 that moves by winding the single string-like body 7 around both the winding drums 5 (5A, 5B) will be described.

First, the string-like body 7 is wound around the winding drum 5 (5A, 5B) of the winch 1 attached to the lower end side of the column 15 and is suspended endlessly in the vertical direction in the vicinity of the column 15 via the pulley 12. The upper end side of the net 11 provided on the guide rope 16 is connected.

In this state, the drive shaft 3 (3A, 3B) of the winch 1 is rotationally driven, whereby the winding drum 5 (5A, 5B) is rotated in the forward direction and the reverse direction so that the string-like body 7 is moved between the pulleys 12. By moving, the net 11 is lifted or lowered along the guide rope 16 to be hung or stored.

At this time, the string-like body 7 crosses the winding drum 5 (5A, 5B) and is wound a plurality of times, and the winding drum 5 (5A, 5B) formed with a plurality of grooves is used. Since the strings 7 are not continuous in a spiral shape, the string-like body 7 is wound in a spiral manner with a slight shift between the winding drums 5 (5A, 5B), and the friction received from the groove portion. Each tension is different due to, for example, loosening or bending when used continuously. However, between the winding drums 5 (5A, 5B), one pressing guide body 6 forms a width L (each roller body 8 (8A, 8B, 8C) in a cylindrical shape along the groove direction, or Each of the plurality of roller bodies 8 is provided in the width direction so as to press and guide each of the wound string-like bodies 7, and each winding drum 5 (5A, 5B) side is provided by an elastic body. Since each of the winding drums 5 (5A, 5B) is pressed and guided while adjusting the pressing force according to the degree of tension of the string-like body 7 wound in each groove. Even if slack or deflection occurs due to friction received from the groove part, the string-like body 7 can be reliably moved to the groove side by adjusting the pressing force, so it can be used continuously. It becomes.

When a plurality of the string-like bodies 7 are wound without intersecting between the winding drums 5 (5A, 5B), the pressing guide bodies 6 are attached up and down along the movement of the string-like body 7. At this time, a plurality of roller bodies 8 are provided along the width L of the number of windings of the string-like body 7, and the load applied to the string-like body 7 and the winding drum 5 ( 5A, 5B) in order to eliminate the slack or bending of the string-like body 7 caused by the difference in tension due to the friction received from the groove portions of the groove portions 5A, 5B). ) To move smoothly.

In addition, while attaching the pressing guide body 6 up and down as described above and attaching it to the groove side of the winding drum 5 (5A, 5B), the rotational driving of the winding drum 5 (5A, 5B) is ensured. It is possible to transmit to the string-like body 7.

The pressing guide body 6 includes two roller bodies among the three roller bodies 8 (8A, 8B, 8C) in the string-like body 7 portion that crosses between the winding drums 5 (5A, 5B). In the portion of the string-like body 7 where 8 is pressed and moved by guide and moved horizontally between the winding drums 5 (5A, 5B), the winding drum 5 is moved in order to be pressed and guided by the remaining one roller body 8. Can be reliably transmitted to the string-like body 7, and the smooth string-like body 7 can be taken in and out.

In each of the above-described embodiments, the two drive shafts 3 (3A, 3B) and the two winding drums 5 (5A, 5B) are attached to the winch body 2, but in the present invention, the number of the drive shafts 3 is as follows. It is not limited to this, and three or four is possible. In short, the drive shaft 3 to which the winding drum 5 is attached may be provided according to the number of string-like bodies 7 that move endlessly.

Moreover, in the said Example, although the moving distance of the string-like body 7 was made the same by providing the winding drum 5 (5A, 5B) with the same diameter on the two drive shafts 3 (3A, 3B), it is different in diameter. By providing the winding drum 5 (5A, 5B), it is possible to adjust the moving distance in the winding drum 5 portion. In this case, the shape of the pressing guide body 6 is also changed, and the roller drum 8 having a large diameter is made to correspond to the winding drum 5 having a small diameter, or the mounting plate 10 is changed.

As described above, the winch 1 is provided with two or more drive shafts 3, and the winding drums 5 having two or more and the same diameter or different diameters are provided to synchronize a plurality of string-like bodies 7 with one winch 1. It is possible to move freely, and it is also possible to move when the moving distances are different.

Moreover, in the said Example, although the string-like body 7 moved from one to the other along the groove | channel of the outer periphery of the winding drum 5, it takes out the string-like body 7 by forming in 2 rounds or 3 rounds. It is also possible to move by setting the capture direction freely.

In addition, the configuration of the winch 1 is simple, and in terms of cost, it can be remarkably reduced as compared with the case where a plurality of conventional winches are installed.

In addition, since it is possible to work using two or more string-like bodies 7 at the same time, even if one is damaged, it can be supported by the other one. Gained the effect.

In each of the above embodiments, the winch 1 is mainly used for moving an indoor net body. However, the winch 1 and the moving system using the winch of the present invention are not limited to this. It can also be used as a paddle for a ball or an outdoor ball-proof net, and it can also be used as a construction lift or a hanging wire for work.

In the above embodiment, the groove of the winding drum 5 is not particularly specified, but even when replacing the string-like body 7 having a different diameter, only the winding drum 5 having an enlarged groove is replaced. Can respond.

Moreover, in the said Example, the mounting plate 10 to which the press guide body 6 was attached so that rocking was possible, and the three roller bodies 8 (8A, 8B, 8C) attached to this mounting plate 10 so that rotation was possible. However, the configuration of the pressing guide body 6 is not limited to this in the present invention. For example, the pressing guide body 6 includes a groove that guides the string-like body 7 and a roller that presses the string-like body 7 along the groove. In addition, the width L of each roller body 8 can also be configured by connecting a plurality of pulleys rotatably around the central axis corresponding to the grooves of the winding drum 5. . In short, if the movement of the string-like body 7 is guided and pressed toward the winding drum 5, the configuration is not particularly questioned.
