DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of arranging a plurality of long hoses such as hydraulic hoses and cables in parallel and binding them to a drum or the like so as to be able to pay out or take up a predetermined length. The present invention relates to a long and multiple parallel flexible binding band that can be used as a power or signal cable or the like that connects a fixed part and a movable part in a substantially U shape.

[0002]

2. Description of the Related Art In civil engineering works and the like, when excavating an underground trench or foundation pile hole and constructing an underground continuous wall or foundation pile, when a hydraulic drive is performed by an underwater excavator, a long hydraulic hose is used. Used.

[0003] The hydraulic hose is wound around a drum fixed on the ground and extends into an underground trench, and is unwound as the excavator progresses. After completion of the excavation, the hydraulic hose rises together with the excavator and is wound around the drum.

There are at least three hydraulic hoses for supplying hydraulic oil to the excavator, for recovering hydraulic oil discharged after operating the excavator to the hydraulic unit, and for draining the hydraulic motor. Is required. The at least three hydraulic hoses hang down in the underground trench.

[0005] Therefore, at least three hydraulic hoses for supply and recovery must be wound around the drum at the same time. However, since the recovery hydraulic hose has a low hydraulic pressure and a high elongation rate over the entire length, there is a problem that the lengths of both hydraulic hoses are different during the operation of the excavator, even if they are the same length.

Therefore, if the supply and collection hydraulic hoses are wound around the same drum and are fed and wound, the collection hydraulic hose is slackened, so that the collection hydraulic hose protrudes from the drum and dances. It is known that there are disadvantages such as falling off from a drum, damaging the outside, and generating noise.

Conventionally, in order to avoid such a situation, a plurality of drums must be arranged on the ground near the underground groove by independently winding supply and recovery hydraulic hoses around separate drums. I had to. Alternatively, the winding drum portion of the same drum is divided into two parts by a disk, and one of them is wound with a hydraulic hose for supply and the other is wound with a hydraulic hose for use.

[0008]

However, in the system in which the supply and recovery hydraulic hoses are individually wound around the drums, it is necessary to install as many drums as the required number of hydraulic hoses. Space is an issue, and separate drive units are required because each must be driven separately for winding or unwinding, which increases running costs and requires control of multiple drums. Therefore, there is a disadvantage that the cost is generally increased, for example, a machine and a special operator are required for that.

In the system in which the body of one drum is divided by a disk and a plurality of hydraulic hoses are wound, the elongation ratios for supply and recovery are different from each other as described above. Since the rotation is the same for both, it is better than winding both around the same body without distinction, but it is the same that the hydraulic hose for recovery may fall off and become unwound, It has the disadvantage that measures to prevent it are necessary.

In view of the above circumstances, it is an object of the present invention to minimize the difference in elongation rate and maintain a predetermined length by bundling and integrating a plurality of hydraulic hoses or the like whose elongation rates change with each other. The present invention provides a long and multiple parallel flexible tying band which can be used.

[0011]

According to the first aspect of the present invention, there is provided a long and continuous parallel flexible tying band having cutout grooves forming a half section of a long object in both sides in the longitudinal direction. An inner shroud made of a flexible elongate body having a substantially rectangular cross-section formed, and a long elongate body having a substantially square cross-section formed in one side in a longitudinal direction with a cutout groove forming a half cross section of the long object And a spacer belt composed of an outer shroud arranged on the outermost side of the connected inner shroud, and an outer shroud, the inner shroud, and a long object which are orthogonal to each other at a predetermined interval in a longitudinal direction of the spacer belt and are integrally fastened. And a band.

According to a second aspect, the long object is a hydraulic hose to be wound around a drum, and according to a third aspect, the long object is a cable for electric power or a signal. It is characterized by the following.

[0013]

[Function] Since a plurality of long objects can be bound by a flexible spacer belt integrally fastened with a band, the difference in expansion and contraction of each long object is absorbed by the spacer belt and converted into expansion and contraction as a whole. A long continuous multiple flexible tying band can be formed.

Therefore, if this is used for binding a plurality of hydraulic hoses of an underground trench excavator, the hydraulic hoses can be wound around the drum, and the hydraulic hoses protrude from the drum and dance, drop off from the drum, and remove the outside. Damage
Further, inconveniences such as generation of noise can be prevented.
