Device for Fixing a Safety Wire Rope to a Structure

The present invention relates to a fixing device for fixing a safety wire rope to a structure, and more specifically, to a fixing device for fixing one end of a safety wire rope to a channel forming a structure for preventing a fall of a worker working on a structure such as a power transmission tower. it's about

A power transmission tower for supporting an electric power transmission wire or communication cable at a high position is a structure formed by combining steel channels horizontally, vertically and diagonally, and a transmission line is supported on the upper end of the structure.

For installation and maintenance of transmission towers and transmission lines, workers climb to a high position of the transmission tower and work. For the safety of workers, a safety wire rope is installed in the transmission tower, and a safety lanyard is installed between the operator and the safety wire rope. Prevents workers from falling.

These safety wire ropes are installed vertically and horizontally in the transmission tower, and the fixing devices to which one end of the safety wire rope are coupled are fixedly coupled to the channels constituting the transmission tower, and the safety wire ropes are installed in the transmission tower by having both ends coupled to the fixing devices, respectively. do.

When a worker falls from a power transmission tower, the load due to the fall is transmitted to the fixing device through the safety wire rope, so the fixing device must have sufficient strength to sufficiently withstand the shock load caused by the worker's fall It should be fixed in the channel of the transmission tower with sufficient strength and stability to prevent it from being separated from the transmission tower by the factors of

Korean Patent Laid-Open Publication No. 10-2021-0039623 (Document 1) discloses a device for preventing a fall of a worker working on a pylon, and the device includes a device for guiding a wire rope for fall prevention.

The guide device disclosed in Document 1 has a shape corresponding to the shape of both ends of a 'L'-shaped channel having a horizontal portion and a vertical portion constituting a pylon, and is disposed through a clamp between a pair of clamps facing each other and the clamps bolts are provided, and the nut is held on the outer surface of each clamp at both ends of the bolt, and a tensile force is applied to a pair of clamps to fix the clamp to the channel.

A hook through which a wire rope passes is attached to the end of the clamp on one side to prevent a worker from falling, and the wire rope is guided so as not to deviate from the position of the channel of the pylon.

Korean Patent Publication No. 10-2202866 (Document 2) discloses a wire clamp mounted on both ends of a 'L'-shaped channel constituting a truss structure of a pylon.

The wire clamp disclosed in Document 2 has a pair of clamps and bolts placed in contact with both ends of the channel by borrowing the structure of the guide device of Document 1 as it is, and one clamp has a ring for fixing one end of the wire rope. The equipped member is fixed.

Since the guide device or the fixing device according to Documents 1 and 2 is coupled to the channel of the pylon by a clamp element having the same shape and a bolt connecting them, the assembly is easy.

However, in these devices, since the clamp element is supported in contact with only both ends of the channel, an impact load is concentrated on the clamp element and the channel, so there is a problem in that the channel or clamp element must be manufactured to have high strength and rigidity.
