Description

The present invention relates to a winch that can move a string-like body such as a wire rope having different diameters and can be freely attached to a drive shaft.

For example, as an example of an outdoor facility that uses a winch that moves a wire rope endlessly, there are a ball game facility such as baseball and a circur, a golf course, or a practice field thereof. The ball-proof net used in these facilities moves the net up and down or opens and closes along the support by moving the wire rope suspended between the support in an endless manner with a winch.
As another method of use, it is used for safety measures at construction sites (especially high-rise construction sites), or for movement of mist and snow protection seats on dam construction and highways.

An example of an indoor facility that uses a winch that moves a wire rope endlessly is a school gymnasium or a multipurpose indoor ballpark having a large space. These facilities are used for opening / closing movement of partition nets or ball nets.

The ball-proof net or the partition net used indoors is either indirectly or 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. A net provided indirectly or directly on the wire rope by moving the net provided directly or opening or moving the wire rope suspended along the arc of the ceiling using a winch Is moving up and down.

The wire rope used outdoors is easily affected by wind, and particularly in facilities where nets / seats are provided, it is strongly affected by wind, and in some cases, the support column may be damaged. Therefore, on windy days, it is necessary to move the wire rope using a winch and quickly store it on a net or the like.

Moreover, in the said indoor facility, the diameter of the wire rope used according to the load of a net | network and the distance to move differs.

Problems to be solved by the invention

However, when moving the wire ropes having different diameters, the conventional winches must use different winches. For example, in a device once installed indoors, the diameters are different for safety. When changing to a wire rope to be used, it is necessary to replace all winches, and the replacement work is complicated, which may lead to a delay in the work.

Further, in changing the wire rope, if the winch is completely replaced, there is a disadvantage that the cost of the winch and the burden of the replacement work are large.

In addition, since the groove provided on the winding drum of the winch is formed in a substantially V shape, depending on the width of the wire rope, it may be difficult to pinch the groove. There was a drawback that it could not be transmitted to the wire rope.

Therefore, the present invention can move the wire rope or the like appropriately with the same winch even in the case of the wire rope or the like having different diameters, and can be easily attached to the conventional facility. It is an object of the present invention to provide a winch that can be used frequently and can be used frequently.

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 having a groove formed on the outer periphery to wind a string-like body such as a wire rope, and a forward / reverse rotation drive of the winding drum. The winding drum winds in a winch that takes in a string-like body such as a wire rope from one side along the groove and moves the string-like body such as a wire rope from the other side. The groove portion is divided into a plurality of portions along the axial direction so as to correspond to the diameter of a string-like body such as a wire rope.

The second means of the present invention comprises a winding drum having a groove formed on the outer periphery to wind a string-like body such as a wire rope, and takes in the string-like body such as a wire rope along the groove from one side. In addition, in the winch in which a string-like body such as a wire rope is taken out and moved from the other side, the winding drum is configured to be divided in the radial direction at the drive shaft portion.

Further, specifically, a movement assisting means for assisting the take-in movement while pressing the take-in side of the string-like body such as a wire rope in the direction of the wind drum in accordance with forward / reverse rotation driving of the wind drum. Or, and / or an outer periphery of the winding drum is provided with a long press moving body provided in close contact with a portion where a string-like body such as a wire rope is wound along the groove. It is.

Effects and effects of the invention

The winch of the present invention first moves a string-like body such as a wire rope to a position in contact with the winding drum, and drives the drive shaft to rotate the winding drum along the outer circumferential groove from one side of the winding drum. Then, it moves so as to wind a string-like body such as a wire rope and takes it out from the other side of the winding drum.

At this time, since the winding drum is divided into a plurality of portions along the axial direction at the groove portion, the width of the groove is adjusted to be enlarged / reduced in accordance with the diameter of the string-like body such as a wire rope in contact with the groove. It is possible to move a string-like body such as a wire rope of all kinds of diameters so as to be surely in contact with the groove.

Therefore, in order to be able to cope with one winch without preparing separate winches according to the diameter of the string-like body such as a wire rope like a conventional winch, in the apparatus once installed, Even if it is replaced with a string with a different diameter for safety, etc. after a certain period of use, it can easily handle the string by simply increasing the diameter of the groove of the winding drum without replacing the winch. Can do.

For this reason, in terms of working time and cost associated with the change of the string-like body, it can be remarkably reduced (reduced) compared to the conventional case.

In addition, when slack / deflection occurs in the string-like body, a long press-moving body provided in close contact with a portion wound along the groove is provided so that the press-moving body is in the form of a string. By moving the body along the winding drum while pressing the body against the groove side of the winding drum, the slack / deflection of the string-like body is suppressed, or when the winding drum is driven forward / reversely, respectively. By providing a movement assist means at a part of or near the outer periphery of the drum, the string-like body is slackened by pressing the take-in side of the string-like body into the winding drum and making the take-out side free from the winding drum. / The occurrence of bending can be suppressed, and a string-like body such as a wire rope can be reliably moved.

In addition, the winding drum is configured to be divided in the radial direction at the drive shaft portion thereof, so that, for example, the divided winding drum is reattached to a drive shaft of a winch of a conventionally installed device, and a string such as an attachment wire rope is attached. By simply winding the shape body around the groove on the outer periphery of the winding drum, it can be easily installed without requiring a large-scale operation such as removing the entire device or winch as in the prior art. It has become possible to reduce time and costs.

Also in this case, a long pressing moving body wound along the outer peripheral groove of the winding drum is provided in the same manner as described above, or a movement assisting means is provided at a part of or near the outer periphery of the winding drum. As described above, it is possible to obtain the operational effect that the string-like body such as the wire rope can be reliably moved while suppressing the slack / deflection of the string-like body.

As described above, the present invention can freely cope with a string-like body such as a wire rope having a different diameter with one winch, is economical, and can greatly expand its use range.

In addition, since the winding drum can be attached using the drive shaft of a conventional winch, the installation is easy and the conventional apparatus can be used.

Hereinafter, an embodiment of the winch of the present invention will be described with reference to the following drawings.

1 to 7 are drawings showing the structure of a winch.
1 is a schematic explanatory view showing a two-part state of a winding drum used in the winch of the present invention, FIG. 2 is a schematic explanatory view showing a winch to which the winding drum of FIG. 1 is attached, and FIG. FIG. 4 is a schematic explanatory view showing a state where the groove portion of FIG. 1 is enlarged, FIG. 4 is a schematic explanatory view showing a three-divided state of the winding drum, and FIG. 5 is a schematic view showing a state where the groove portion of FIG. FIG. 6 is a schematic explanatory view showing a state where the winding drum is divided into two at the drive shaft portion, and FIG. 7 is a schematic front view showing the winch to which the winding drum of FIG. 6 is attached, FIG. 8 is a schematic explanatory view showing a state where the movement auxiliary body 6 is provided on the outer periphery of the winding drum.

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); A substantially circular winding drum 2 provided on the drive shaft 12 and having a substantially V-shaped groove 2A formed on the outer peripheral side surface, and a string-like body 7 is taken into the winding drum 2 from one side and from the other side. Two guide rollers 3 rotatably supported in parallel positions on the intake side and the take-out side, respectively, in order to assist in taking out the string-like body 7 from the winding drum 2, and the guide roller 3 A guide guide 4 is provided between the guide drum 3 and a guide drum 4 that guides the string-like body 7 while being sandwiched between the guide drum 3 and the guide drum 3.

In the winding drum 2, the bottom surface portion (width M1) of the groove 2A is divided into two (2a, 2b) along the axial direction, and is limited to three points (three points) in the middle of the winding drum 2. The adjusting screw 11 is provided at two or four points, and the division width (M2) is adjusted by the adjusting screw 11 and the entire winding drum 2 is fixed.

The division of the groove 2A of the winding drum 2 at the bottom surface portion (width M1) is not limited to two divisions. For example, three divisions (2a, 2b, 2c) of both side surfaces and the bottom surface portion of the groove 2A are performed. ), The width (M3) of the groove 2A can be enlarged as described above. In short, the dividing method is not particularly limited as long as the groove 2A can be enlarged in a stable state.

Further, the winch 1 of the present invention clearly describes the characteristics of the winch main body portion, and a drive source that is normally used is used as the drive source (particularly when the rotational drive of the winding drum 2 is electric). Therefore, a known technique is used to use an electromagnetic brake or the like for the brake mechanism, or to use a crack mechanism or the like, or to provide an auxiliary brake for safety.

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 side of the guide guide 4 ( On the intake side), the winding drum 2 is provided along the groove 2A by rotational drive, moves along the rotational drive, and is taken out from the other along the guide guide 4 again (extraction side).

The winch 1 of the present invention is constructed as described above, and the operation of the winch 1 will now be specified.

First, after confirming the diameter of the string-like body 7 such as a wire rope in an apparatus used indoors and outdoors, the diameter (M1) of the groove 2A portion of the winding drum 2 of the winch 1 to be used is set to an appropriate diameter (M2). Adjustment is performed using the adjusting screw 11.

Thereafter, the winches 1 are respectively installed, and a string 7 such as a wire rope is wound around the winding drum 2 and suspended. If the string 7 having a different diameter is changed for safety or the like after a certain period of use, the installed winch 1 is left as it is, and the groove 2A portion of the winding drum 2 using the adjusting screw 11 is used. By simply enlarging and adjusting the diameter (M1), the string-like body 7 having different diameters can be easily changed.

In addition, in the case of indoors, even when a space portion is partitioned using a plurality of string-like bodies 7 having different diameters, the winding is performed without preparing a plurality of types of winches as in the prior art. Since only the diameter (M1) of the groove 2A portion of the drum 2 can be adjusted, the winch 1 can be changed to a string-like body 7 having a different diameter even after the winch 1 is installed. Work becomes simple and all correspondence becomes possible.

Therefore, it is possible to cope with the string-like bodies 7 having different diameters with the optimum groove width with one kind of winch 1.

Further, when the string-like body 7 is slackened / bent and cannot be moved smoothly due to the difference or type of the diameter of the string-like body 7, the take-in side / string-like body of the string-like body 7 to the winding drum 2 is not possible. This is achieved by providing a movement auxiliary body 6 on each of the 7 take-out sides.
In this case, the take-in side of the string-like body 7 to the winch 1 takes in and moves the string-like body 7 while pressing the string-like body 7 toward the groove 2A of the winding drum 2 by the rotating or swinging movement assisting body 6. On the take-out side 7, the rotating or swinging movement auxiliary body 6 is separated from the winding drum 2, and the pressing to the groove 2 </ b> A side of the winding drum 2 is released to enter a free state, and the string-like body 7 is smoothly taken out. Will be. Further, as another embodiment of the movement assisting body 6, it is possible to obtain the same effect as described above by providing a part of the winding drum 2 so as to swing both ends via the fulcrum 6 </ b> A. .

For the occurrence of slack / deflection of the string-like body 7, in addition to the movement assisting body 6 as described above, a pressing movement comprising a roller chain or the like that presses the string-like body 7 against the groove 2 </ b> A on the outer periphery of the winding drum 2. It is also possible to provide a body 8. In this case, the pressing and moving body 8 is pulled in one direction of rotation of the winding drum 2 and the take-in side of the string-like body 7 to the winding drum 2 is pressed, and the string-like body 7 is wound. Since it can move in the state pressed against the peripheral surface of the drum 2, there is no loss of force during movement of the string-like body 7, and appropriate movement is possible.

Next, another embodiment of the winch of the present invention will be described.

The winch 1 of the present embodiment is provided in the winch body 1A, and a hole 12C for attaching a drive shaft 12 to be rotated and a groove 2A having a substantially V-shaped cross section formed on the outer peripheral side surface to be attached to the drive shaft 12.

And two guide rollers 3 that are rotatably supported in parallel positions on the take-out side and the take-out side, respectively, and the string-like body 7 is route-guided while being sandwiched between the guide rollers 3 and the guide drum 3 It consists of a guide 4.

The winding drum 2 is divided into two vertically (upper part 2H, lower part 2G) at the central hole 12C, and can be freely attached to the drive shaft 12 by the division.

The method for dividing the winding drum 2 is not limited to the above-described two divisions, and can be divided into three or more according to the installation location and the material or shape of the winding drum 2.

The winch 1 of the present invention has the above-described configuration, and its operation will be specified next.

First, the winch 1 of the present invention is usually installed in each facility as the winch 1, the string-like body 7 is taken into the winch body 1 </ b> A with the guide roller 3 and the guide drum 3 being sandwiched, and the outer periphery of the winding drum 2 is It winds and moves along the groove 2A, and is taken out from the winch body 1A while being sandwiched between the guide roller 3 and the guide drum 3 from the other side.

Since the winch 1 of the present invention can mainly use the winch body 1A, for example, a case where the winch 1 is attached to a drive shaft of a winch installed in another facility will be described.

First, the winding drum 2 portion is divided, the drive shaft is inserted into the hole 12C of the winch body 1A, and then the winding drum 2 portion is attached, whereby the conventional winch drive shaft can be used.

In this case, similarly to the above, the string-like body 7 can be wound around the winding drum 2 and suspended, and if the string-like body 7 is slack / deflected, This can be dealt with by providing the pressing moving body 8 on the outer periphery or by providing the movement assisting body 6 on the take-in side of the string-like body 7 to the winding drum 2.

Thus, since the winch 1 of the present invention can move the string-like body 7 using only the drive shaft of the winch without changing the conventional apparatus, the working time required for installation is remarkably shortened. be able to.

Further, in a facility where a conventional winch is used, the winch 1 of the present invention can be connected to the conventional winch to assist the conventional winch function, and the use thereof can be greatly improved.
