Description

The present invention relates to a winch that is used to move endlessly a string-like body such as a wire rope provided with a net or a sheet.

For example, when moving a net or seat in a partition system using a net in an indoor facility, a UV cut sheet opening / closing system used for an outdoor pool, etc., or a ball-proof net lifting system in a golf driving range, An endless winch is used to move the wire rope endlessly.

Specific examples of the partition system using the net in the indoor facility include an endless winch, a wire rope for a winch suspended in a loop through a pulley along an indoor side or ceiling, and the winch Using a device composed of a plurality of lifting wire ropes connected at one end to a wire rope and a net connected to the other end of the lifting wire rope, the winch winding drum is moved in the forward direction (forward direction). Rotate in the reverse direction (counterclockwise) and move the winch wire rope endlessly to move the lifting wire rope connected to the winch wire rope up and down. The net connected to the lifting wire rope is suspended in the space portion or stored on the floor side, and the space portion is partitioned / opened by the net. (Reference Japanese Patent Laid-Open No. 2003-117046)

In addition, as a specific example of a system for opening and closing a UV cut sheet used for the outdoor pool and the like, an endless winch, a winch wire rope suspended in a loop on the upper side of the pool between pulleys, Winding a winch using a device composed of a guide wire rope suspended in parallel to a winch wire rope and a UV cut sheet provided on the guide wire rope via a connector. The direction in which the UV cut sheet provided on the guide wire rope through the connector is closed along the guide wire rope by rotating the drum in the forward / reverse direction and moving the winch wire rope endlessly. The space portion is closed / opened by moving in parallel or moving in the opening direction. (Japanese Patent Laid-Open No. 2004-285821)

In addition, as a specific example of the lifting system for the ball-proof net of the golf driving range, a plurality of endless winches are suspended in a loop between the pulleys provided in the vertical direction of each column that divides the outdoor space. Using a device composed of a plurality of winch wire ropes and a ball-proof net attached directly to the winch wire rope, the winding drum of each winch is rotated in the forward / reverse direction, A plurality of winch wire ropes are moved up and down between the upper and lower columns to suspend the ball-proof nets, or moved down between the upper and lower columns to store the ball-proof nets. (Japanese Unexamined Patent Publication No. 2000-034792)

In each of the above systems, the wire rope is subjected to its own weight and a load such as a net, and the load is different between the take-in side and the take-out side of the winch that moves the wire rope. Looseness or deflection occurs in the wire rope. In order to eliminate the slack, etc., a winch has been developed in which a guide guide, a guide roller, and a press moving body are provided along the outer peripheral groove of the winding drum in the winch body (Japanese Patent Laid-Open No. 2000-351580, etc.).

Problems to be solved by the invention

However, the winch conventionally used is provided with a guide guide, a guide roller, and a pressing moving body in the vicinity of the winding drum of the winch body, so that the wire rope is taken in and moved to the winding drum side. Pressing can eliminate slack and bending of the wire rope and perform smooth movement, but since each pressing means is configured integrally with the winch body, there is no load on the wire rope when the winding drum rotates. There is a drawback that the wire rope is heavily worn and requires frequent maintenance.

Further, in the conventional winch, since the pressing moving body is provided so as to synchronize with the winding drum, the pressing force to the outer peripheral groove side of the winding drum is the same force (maintains a constant force). The adjustment requires complicated work such as changing the mounting position of the pressing moving body.

In addition, in the conventional winch, the loosening and bending that occur in the wire rope have been eliminated by pressing the outer circumference of the winding drum toward the groove side, but the loosening and deflection that occurs in the wire rope has been eliminated. It is possible to move the wire rope more smoothly if it is performed in the vicinity.

In addition, in the indoor and outdoor areas, the direction of taking out the wire rope from the winch and the direction of taking in the winch may differ depending on the installation space of the winch. However, in the conventional winch, the direction of taking out the wire rope and the winch are different. Since the direction of taking in the wire is constant in the same direction, it is necessary to adjust the direction of taking in and out of the wire rope with respect to the winch using a number of pulleys, and the direction of suspension, and the adjustment is complicated. With this, there was a drawback that the wire rope suspension system had to be changed.

Accordingly, the present invention aims to provide a winch that moves a string-like body such as a wire rope smoothly in order to solve the above-mentioned problems, has little wear on the wire rope, is easy to install a winch, and is safe. And

Means for solving the problem

A first means as a winch for solving the above-described problems of the present invention is that a string-like body such as a wire rope wound around a groove formed on the outer periphery is taken in and taken out from the winch as described in claim 1.

Further, since the groove-side pressing formed on the outer periphery of the winding drum by the belt-like body and the swinging pressing body are interlocked with each other, the cord-like body such as a wire rope can be taken into the winch and taken out from the winch. The movement can be done with a swirl.

As described above, the winch of the present invention can appropriately adjust the taking-in and taking-out of the string-like body such as the wire rope to the winding drum by the swinging pressing body, so that the winding drum can be driven reliably. It can be conveyed to a string such as a rope.

In addition, by interlocking with the belt-like body, it is possible to reliably cope with differences in load in the direction of taking in and taking out the string-like body such as a wire rope.

In addition, the present invention suppresses the wear on the string-like body such as the wire rope that occurs when the bending or slack in the conventional endless winch is eliminated, and enables the smooth movement of the string-like body such as the wire rope, Maintenance work can be reduced.
