DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for a hydraulic hose , and more particularly to a winding device for a plurality of hydraulic hoses used to supply hydraulic pressure to various equipment.

[0002]

2. Description of the Related Art Various hydraulic devices are used in construction sites of civil engineering and construction, factories and the like. The hydraulic pressure as the power source of the device is transmitted from the hydraulic pressure supply source to the device at the tip end via the hydraulic hose. These hydraulic hoses have a length that can follow the range of movement of advanced equipment.When the amount of movement of equipment is small, the remaining hydraulic hoses can be hung in tufts or collected on the ground manually. However, depending on the structure of the hydraulic equipment and the work space, the work site becomes complicated, which causes a problem in work efficiency and safety management.
On the other hand, there is known a method of winding the hydraulic hose by using a reel in order to organize the remainder of the hydraulic hose compactly and prevent complication.

[0003]

However, in such a conventional method of winding a hydraulic hose, a predetermined hydraulic pressure,
For example, for a hydraulic hose with a diameter of about 25 mm that is used to supply a relatively small hydraulic pressure of about 210 kg / cm ^2, it is possible to wind two or three hydraulic hoses at the same time, but the size of the advanced equipment increases. Therefore, when the diameter and the number of hydraulic hoses increase, irregular winding occurs, which makes it difficult to wind them simultaneously. In order to deal with this, it is possible to increase the number of reels, but it is not easy to set a large number of reels in a place where the work space is narrow. Further, there is a problem that the hydraulic hose is stretched due to the winding force and its own weight during winding.

Therefore, the present invention has been made to solve the above-mentioned problems, and makes it possible to wind a plurality of hydraulic hoses in an orderly manner without causing irregular winding.
An object of the present invention is to provide a hydraulic hose winding device capable of preventing the hydraulic hose from being stretched due to a winding force or its own weight.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned object, and its gist is a winding device for winding a plurality of hydraulic hoses for supplying hydraulic pressure to various equipment by a reel. there are, in order to juxtaposed without intersecting the hydraulic hose, and clip means each of which holds a plurality of hydraulic hoses in a row while being disposed at a predetermined interval in the longitudinal direction of the hydraulic hose, 該Ku The clip means is composed of at least two pulling members that connect the lip units to each other and support the winding force of the reel and the weight of the hose continuously in the lengthwise direction of the hydraulic hose , and adjacent to the pulling members. A series of insertion holes for connecting the pulling member are formed continuously, and when the reel is wound, the gap between the reel and the pulling member and the radial direction of the reel are overlapped. Meet in the winding device for a hydraulic hose having a guide means which retains the spacing between the traction member.

Further, in the winding device for the hydraulic hose of the present invention, a series of insertion holes for inserting the pulling member are formed continuously between the adjacent clip means, and at the time of winding on the reel. , The distance between the drum outer circumference of the reel and the pulling member and the distance between the pulling members overlapping in the reel radial direction are substantially the same as, for example, the distance between the drum outer circumference and the center of the hydraulic hose and the center distance between the hydraulic hoses overlapping in the reel radial direction. It is also possible to further provide a guide means for the pulling member that holds the space at the interval.

[0007]

In the present invention, the clip means has, for example, a row of openings partitioned at predetermined intervals, holds the hydraulic hoses in the respective openings, and clips arranged at predetermined intervals in the longitudinal direction of the hydraulic hose. Since the means holds the hydraulic hoses in each opening in the same order, it is possible to arrange a plurality of hydraulic hoses side by side in a row without crossing. Further, the traction member connects adjacent clip means and is continuous in the longitudinal direction of the hydraulic hose, and bears the pulling force applied to the hydraulic hose due to winding, self-weight, etc. to prevent the hydraulic hose from extending. Further, by providing a guide means which is continuously provided between the adjacent clip means and forms a series of insertion holes for inserting the pulling member, when the reel is wound by the reel, the outer circumference of the drum of the reel and the pulling member are provided. The spacing and the spacing between the pulling members that overlap in the reel radial direction are maintained at a spacing that is substantially the same as the spacing between the drum outer circumference and the center of the hydraulic hose and the spacing between the hydraulic hoses that overlap in the radial direction of the reel, respectively. The hydraulic hose can be efficiently wound by the traction force of the traction member without causing slack in the hydraulic hose.

[0008]

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a hydraulic hose take-up device 11 of the present invention is used as an excavating device 10 for cutting the ground to construct an underground wall. That is, the eight hydraulic hoses 13 for supplying hydraulic pressure to the cutting cutter 12 and other devices attached to the tip of the excavator 10 are arranged at predetermined intervals in the longitudinal direction of the hydraulic hoses, for example, at intervals of about 1.3 m. Wires 15 that are arranged and held in a row in parallel by the arranged clips 14 and that connect the clips 14 to each other are formed by a top 16 as a guide means that is continuously provided between the clips 14 at both ends of the clips 14. It is arranged in the hole. Then, following the cutting depth of the excavator 10, the reel 17 is rotated to unwind the hydraulic hose 13 via the pulley 18, or after the cutting is completed, the cutting cutter 12 is lifted and the hydraulic hose 13 is wound.
