These technologies are commonly to install a safety rope in a fixed installation, such as a transmission tower.

However, when the safety rope is fixedly installed in the facility, there is a problem that the safety rope is installed in the facility even when not working, and it is easily deteriorated by rain, wind, or sunlight, etc. Even if the safety rope is damaged by any factor, there is a problem that the operator or facility manager cannot confirm the damage.

Document 1: Korean Patent Publication No. 10-2031562 Document 2: Korean Patent Publication No. 10-1322660

In this invention, when not working on the facility, the safety rope is not installed, but a method was considered to allow the safety rope to be installed during the operation.

As such, a safety rope installation system has been proposed in which the installation wire is installed in the facility instead of the safety rope, and the safety rope is disposed at the location of the installation wire instead of the installation wire during work.

This invention, in the above-described installation system of the safety rope, allows the installation wire to be placed in the facility, and the safety rope is towed by the installation wire in the operation of recovering the installation wire and recovering the installation wire at the time of operation of the installation wire It is intended to provide a winding machine that allows it to be placed in position.

In particular, it is intended to provide a winding machine that does not have a complicated configuration such as a motor or a sensor, but is composed of simple and inexpensive elements so that a worker can easily and safely install a safety rope.

The present invention relates to a winding machine that is installed in a facility to be operated at height adjacent to the ground and used to install a safety rope for work at height in the facility.

The installation system of the safety rope in which the winding machine of this invention is used,

The safety rope is installed by being fixed to the winding machine at both ends, extending along the facility to be operated at height, and wound on a roller that is arranged on the upper part of the winding machine in the facility, and both ends are fixed to the winding machine and extended to the upper part of the facility to be wound on the roller. When a wire is provided, when the safety rope is installed, one end of the safety rope is combined with one end of the installation wire and the installation wire is wound with a winding machine. By passing the roller and returning to the winding machine, the installation wire is replaced by one end of the installation wire to which the safety rope is coupled. Thus, the safety rope is placed at the installation location.

Winding machine according to the present invention,

a housing coupled to and installed in a facility; A drum having a rotating shaft and rotatably coupled to the housing, one end of the installation wire is fixed and the installation wire is wound by rotation; a handle coupled to the rotating shaft of the drum and allowing the operator to rotate the rotating shaft; and a ratchet mechanism for switching between a state in which the drum is rotatable in only one direction and a state in which the drum is rotatable in both directions;

When the safety rope is installed, one end of the safety rope is connected to the other end of the installation wire and the ratchet mechanism is switched to a state where the drum can rotate in only one direction. Instead of the installation wire, it is arranged at the arrangement position of the installation wire in the facility.

According to this configuration, as a configuration for installing a safety rope in a facility subject to work at height, a roller is installed on the upper part of the facility and the winding machine according to the present invention is installed in a position adjacent to the ground, and a safety rope is installed between the winding machine and the roller The installation wire used to install is extended.

To install the safety rope, release one end of the installed wire for installation fixed to the winding machine, and couple one end of the safety rope to the released end. Then, the ratchet mechanism is switched to a state in which the drum can rotate in only one direction, and the drum is rotated with a handle so that the installation wire is wound around the drum.

The installation wire is wound on the drum from the end fixed to the drum, and the opposite end to which the safety rope is coupled is pulled. Thereby, the safety rope is towed by the installation wire and is arrange|positioned at the position where the installation wire was installed.

When the end of the installation wire to which one end of the safety rope is coupled reaches the winding machine, the end of the safety rope is released from the end of the installation wire and fixed to the winding machine.

Thereby, the installation wire is wound on the drum of the winding machine, and the safety rope is extended between the winding machine and the roller and disposed in the facility, so that the operator can perform the work at height on the facility while securing safety using the safety rope.

When the work at height is completed and the safety rope is retrieved, the ratchet mechanism is switched to a freely rotatable state, one end of the installation wire is coupled to one end of the safety rope, and the other end of the safety rope is pulled.

Accordingly, the safety rope is recovered and the installation wire is disposed at a location where the safety rope is installed instead of the safety rope. When all of the safety rope is recovered, the end of the installation wire coupled to one end of the safety rope is released and fixed to the winding machine.

On the other hand, during the installation of the safety rope, the installation operation of the safety rope can be stopped and the operator can perform other operations without manipulating the handle.

The weight per unit length of the installation wire and the safety rope may be different, and in this case, the load on both sides centered on the roller during installation of the safety rope is different, so the force may act in the direction in which the safety rope being towed is descending.

However, since the rotary shaft of the drum can be rotated only in the direction of pulling the installation wire by the ratchet mechanism, the safety rope does not fall while the drum rotates in the opposite direction and the installation wire is released from the drum.

In addition, in the operation of recovering the safety rope, since the ratchet mechanism can rotate the drum in both directions, a force that promotes the rotation of the drum by the weight of the safety rope can act. At this time, the operator controls the rotation speed of the drum by gripping the handle, thereby promoting the rotation of the drum by the weight of the safety rope, thereby preventing the safety rope from falling at high speed.

In this configuration of the present invention, the ratchet mechanism,

a ratchet wheel coupled to the rotating shaft of the drum and rotating together with the drum; and

The ratchet bar may be configured to include a ratchet bar rotatably provided between an operating position in engagement with the ratchet wheel and allowing only one-way rotation of the ratchet wheel and an inoperative position in which the disengagement of the ratchet wheel is released from the leading end.

By simply configuring the ratchet mechanism with a simple manually operated lever and a wheel in which the tip of the lever is engaged, control is easy and the manufacturing cost of the winding machine is reduced.

As an additional feature of this invention, the winding machine of this invention.

It can be configured to further include a winding guide means having a portion through which the installation wire passes and moving along the axis of the rotating shaft of the drum to guide the position where the installation wire is wound on the drum.

When the winding guide means is moved along the axis of the rotating shaft of the drum while rotating the drum with the handle in the operation of winding the mounting wire on the drum, the position at which the mounting wire is wound around the drum moves along the axis of the rotating shaft. Therefore, the wire for installation can be wound evenly around the drum.

As an embodiment of such a winding guide means,

Winding guide means,

a guide bar extending parallel to the rotation axis of the drum and installed in the housing; and

It can be slidable along the guide bar, and can be configured to include a guide block in which a portion through which the installation wire passes is provided.

A fixing ring 60 for fixing both ends of the safety rope 8 is provided on the outer surface of the housing 10 .

After the safety rope 8 is installed at the installation position of the installation wire 7, both ends of the safety rope may be fixed to the transmission tower 1, but in the fixing ring 60 provided in the winding machine 100 of the first embodiment Both ends of the safety rope (8) are fixed respectively.

The operation of the winding machine of the first embodiment having the above configuration will be described.

In the state where the transmission tower 1 is installed, a roller 110 is installed on the upper end of the transmission tower 1, and a winding machine 100 is installed at a position close to the ground where the operator can approach and work, and the roller 110 and A guide bar 120 is installed between the winding machine 100 .

The installation wire 7 has one end fixed to the drum 20 and the other end fixed to the fixed ring 17 , extending between the roller 110 and the winding machine 100 at the top of the transmission tower 1 .

When the safety rope 8 is installed to work in the transmission tower 1, one end of the installation wire 7 fixed to the fixing ring 17 is released, and as shown in FIG. 1, the connection rope 9 Connect one end of the safety rope (8) to the installation wire (7) using

When the connection is completed, the ratchet bar 41 is rotated so that the tip is placed in contact with the gear 31 of the ratchet wheel 30 . The drum 20 is rotated by the handle 22 of the winding machine. The rotation direction of the drum 20 is made in one rotatable direction of the ratchet wheel 30 .

Accordingly, the installation wire 7 is pulled and wound around the drum 20 , and the other end to which the safety rope 8 is connected is pulled up toward the top of the transmission tower where the roller 110 is installed.

The operator rotates the drum 20 with the handle 22 and simultaneously moves the guide block 53 of the winding guide means 50 so that the installation wire 7 is wound side by side on the drum 20 .

According to a winding operation, the safety rope 8 is arrange|positioned at the position where the wire 7 for installation was installed, and the wire 7 for installation is wound around the drum 20.

The installation wire 7 may be made of a stainless steel material having a thickness of 3 mm, and a synthetic fiber rope having a thickness of 14 mm may be used as the safety rope 8 in general. Accordingly, the installation wire and the safety rope may have different weights per unit length.

In the middle of the winding operation, there is a case in which the operator must release his hand from the handle 22 and perform another operation. In a state in which the safety rope 8 is not completely installed, the weight of the installation wire 7 and the safety rope 8 suspended on both sides around the roller 110 may be different.

Due to this weight difference, the safety rope 8 suspended from the transmission tower can be pulled to the ground. However, since the ratchet wheel 30 is rotated in only one direction by the ratchet bar 41, the drum 20 rotates only in the direction in which the installation wire 7 is wound and cannot rotate in the direction in which the installation wire 7 is unwound. , It does not happen that the wire 7 for installation is unwound while the drum is unintentionally reversely rotated by the weight of the safety rope 8 being installed in the power transmission tower 1 .

When the end of the installation wire 7 to which the safety rope 8 is coupled approaches the winding machine 100, the operator releases the end of the safety rope 8 from the installation wire 7 and attaches to the fixing ring 60 of the winding machine. Secure both ends of the safety rope (8).

Thereby, the installation wire 7 is separated from the transmission tower 1 and the safety rope 8 is installed on the transmission tower, so that the operator can climb to the working position of the transmission tower 1 using the safety rope 8 .

When the work in the transmission tower 1 is completed, the safety rope 8 is released from the transmission tower.

The safety rope (8) releases one end from the fixing ring (60), and the end of the wire (7) for installation is coupled thereto. In addition, by rotating the ratchet bar 42 to release the state engaged with the ratchet wheel 30, the drum 20 can rotate in reverse.

When the safety rope 8 is pulled, the drum 20 rotates in reverse, and the wire 7 for installation is released from the drum 20 while the safety rope 8 is installed.

As the safety rope 8 falls by the weight of the safety rope 8, the drum 20 rotates at a high speed and the wire 7 for installation can be released at a high speed. This situation may result in personal injury or damage to the winding machine and other equipment.

The operator can prevent the safety rope 8 from dipping by gripping the handle 22 and allowing the drum 20 to rotate in reverse at an appropriate speed.

When the safety rope 8 is all released from the transmission tower 1 and the installation wire 7 is placed in the place of the safety rope 8, the end of the installation wire 7 is fixed to the fixing ring 17 inside the housing . This completes the release of the safety rope 8 and the reinstallation of the wire for installation.
