Abstract

PURPOSE:To restrict a bundle body without loosing it by spirally winding one or more of bands on the outer circumference of a lengthy bundle body in one direction, and spirally winding one or more of other bands on the outside thereof in the other direction. CONSTITUTION:Around an unrestricted lengthy bundle body 17, one or more of bands 6 consisting of elastic bodies are wound in one spiral direction at a pitch according to the longitudinal moving speed of the lengthy bundle body and the rotating speed of a rotating drum 3, and also around the outer circumferential part thereof, one or more of bands 6 consisting of elastic bodies are wound in the other spiral direction, whereby the lengthy bundle body is bundled. Against deformations such as bending, expansion and contraction, increase and decrease in diameter of the lengthy bundle body 17, the spirally wound bands 6 are expanded and contracted to fasten this body. Consequently, the lengthy bundle body 17 is never loosed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a single long length hose that can be used to bundle a plurality of hydraulic hoses, cables, etc. that are fed out into the water so that they do not get tangled, especially when submerging underwater work equipment to the bottom of the water. It is related to the method of binding the body.

[Conventional technology]

Underwater work equipment is lifted by a crane on a work boat and submerged deep into the water, and hydraulic hoses, cables, etc. to operate and control the equipment are brought out into the water. Although these items were paid out at the same time, the hydraulic hoses, cables, etc. were paid out separately.

[Problem to be solved by the invention]

Underwater work equipment has multiple hydraulic hoses and cables connected to the main body of the equipment in order to carry out various tasks, and because these are long, for example, in addition to the ocean currents in the sea, the underwater work equipment itself Due to the movement associated with the work, these items become tangled or twisted.

Next, when the specified work is completed, this underwater work equipment is pulled up, but at that time, each hydraulic hose must be wound up independently on separate reels, so the hydraulic hoses are often tangled or twisted. There was a problem with work efficiency in that the cable had to be unraveled and wound up.

In order to prevent such problems, these may be tied together with strings or the like in advance.

However, such bundling work is sometimes carried out manually by workers, resulting in problems such as poor work efficiency and poor reliability.

Accordingly, an object of the present invention is to provide a method for bundling flexible elongated bodies that can highly efficiently and reliably bundle hydraulic hoses and cables.

[Means for resolving issues]

The present invention has been made to solve the above-mentioned problems, and therefore, the method for bundling flexible elongated bodies according to the present invention is characterized by: are brought into contact to form an unrestrained long bundle, and the long bundle is passed through the center of rotation of a rotary drum having a bobbin around the outer periphery around which a string made of an elastic body is wound, and the long bundle is placed in a predetermined direction in its longitudinal direction. While moving at a high speed, the cord continues to be fed out while rotating the rotating body, one or more straps are wound around the outer periphery of the long bundle in a spiral shape in one direction, and the outside of the cord is wound around the outer circumference of the long bundle in a spiral shape. It is made by wrapping one or more obi cords in a spiral in the other direction.

[Effect]

According to the method for bundling flexible elongated bodies according to the present invention, the unrestrained elongated bundles have one or more elastic bands in one helical direction at a pitch that corresponds to the moving speed in the longitudinal direction and the rotational speed of the rotary drum. The body is wrapped with a band string, and the outer periphery is wrapped in another spiral direction with a band string made of one or more elastic bodies and bundled.

When the long bundle is deformed, such as by bending, expanding or contracting, or expanding or contracting its diameter, the spirally wound webbing string expands and contracts to tighten it, so the long bundle does not come apart. do not have.

〔Effect of the invention〕

According to the method for bundling portable elongated objects according to the present invention, the unrestrained elongated objects can be moved at a pitch corresponding to the moving speed in the longitudinal direction and the rotational speed of the rotary drum without the need for manual work such as an operator. The outer periphery is wrapped in one helical direction by a strap made of one or more elastic bodies, and the outer periphery is wrapped and bundled in the other spiral direction by a strap made of one or more elastic bodies. When the bundle is deformed by bending, expanding or contracting, or expanding or contracting its diameter, the spirally wound webbing string expands and contracts to tighten the bundle, so the bundle does not come apart (which reduces reliability). Excellent restraint is possible.

If multiple hydraulic hoses and cables bundled in this way are used to operate and control underwater work equipment, even if they are long, they will not get tangled or twisted by ocean currents, so they can be used for specific tasks. There is no need to disentangle the tangles when quoting upon completion of the citation, and the work of pulling up the citations can be done easily.

Therefore, it is possible to shorten the construction period and save labor by using the underwater work device, and as a result, the construction cost using the underwater work device can be significantly reduced, and the economic effect thereof is extremely large.

Therefore, according to the present invention, it has been possible to establish an extremely excellent and useful method for bundling flexible elongated bodies that can efficiently and reliably bundle hydraulic hoses and cables.
