Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hose clamp for a construction machine, and more particularly to a hose clamp corresponding to an increase or decrease of a hydraulic line and a change in the curved shape of the hydraulic line accompanying rotation of an attachment .
[0002]
[Prior art]
FIG. 5 shows a hydraulic excavator 1 as an example of a construction machine. A hydraulic line 4 is piped between the airframe 2 and the boom attachment 3, and the hydraulic line 4 is bundled by a hose clamp 5 and fixed to the boom attachment 3. It is. As shown in FIGS. 5 and 6, the conventional hose clamp 5 is made of a metal strip such as a steel plate or an aluminum plate, has a length equal to or greater than the installation width of the plurality of hoses 6, 6. , 6... Are pressed from above or from the side and fixed with bolts 7 or the like. In the illustrated example, the hose clamp 5 is curved in accordance with the outer shape of the hose 6 and has a waveform when viewed from the front.
[0003]
[Problems to be solved by the invention]
The conventional hose clamp is made of metal and its size is determined in advance, so if the hydraulic line is changed, it will not be possible to respond to the increase or decrease of the hose, and another hose clamp must be prepared. I had to. Further, since the hose is pressed against the hose clamp, there is a possibility that an unreasonable force acts on the hose against a change in the curved shape of the hydraulic line accompanying the rotation of the attachment.
[0004]
Therefore, there is a technical problem to be solved in order to provide a hose clamp corresponding to the increase / decrease of the hydraulic line and the change of the curved shape of the hydraulic line accompanying the rotation of the attachment. The present invention aims to solve this problem.
[0005]
[Means for Solving the Problems]
The present invention has been proposed to achieve the above object, and is a hose clamp for bundling a hydraulic line piped between an airframe and a boom attachment, and the hose clamp is a flexible belt-like sheet. forming a through hole of the tie wire is perforated in the appropriate intervals in the belt-like sheet, substantially of the hydraulic lines the ends of the belt-shaped sheet when surrounding the hydraulic line by bending the belt-like sheet in the longitudinal direction A belt-like sheet is placed on a part of the hydraulic line by being positioned so as to be overlapped with the central portion and by sewing a gap between the hydraulic lines from one side of the belt-like sheet surrounding the hydraulic line to penetrate the binding line to the other side of the belt-like sheet. while fixed, to provide a hose clamp of the construction machine which is fastened to the belt-like sheet by the binding wire as a gap between the hydraulic line and the belt-like sheet other than hydraulic line which is fixed to the belt-like sheet It is intended.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. For convenience of explanation, the same reference numerals are used for the same components as in the prior art. FIG. 1 shows a hydraulic excavator 1 as an example of a construction machine. A hydraulic line 4 is piped between an airframe 2 and a boom attachment 3, and the hydraulic line 4 is bundled by a hose clamp 11.
[0007]
As shown in FIG. 2, the hose clamp 11 is made of a flexible belt-like sheet 12, and is formed of a sheet of synthetic resin or synthetic rubber, for example. In the longitudinal direction of the belt-like sheet 12, holes 13, 13... Are perforated at appropriate intervals, and the belt-like sheet 12 is curved in the longitudinal direction to surround the hydraulic line 4. The ends 12 a and 12 a are fastened with a binding wire 14.
[0008]
When the ends 12a, 12a of the belt-like sheet 12 are fastened together by the binding wire 14, the belt-like sheet ends 12a, 12a are positioned so as to overlap each other at a substantially central portion of the hydraulic line 4. A gap between a plurality of hoses constituting the hydraulic line 4 is sewn from one side of the belt-like sheet 12 surrounding the hydraulic line 4, and the binding wire 14 is passed through to the other side of the belt-like sheet 12 to be fixed . That is, the central hose 15 is fixed to the belt-like sheet 12 through the binding wire 14 above and below the central hose 15. In addition, a gap is provided between the hose other than the hose 15 at the center and the belt-like sheet 12.
[0009]
Thus, even if the boom attachment 3 rotates and the curved shape of the hydraulic line 4 changes by bundling the hydraulic line 4 with the hose clamp 11 composed of the belt-like sheet 12, the hoses are bundled. Therefore, there is no risk of interference with other objects. Further, since there is a gap between the hose 15 other than the central hose 15 and the belt-like sheet 12, when the curved shape of the hydraulic line 4 changes, the upper and lower hoses appropriately slide in the longitudinal direction, It is possible to prevent excessive force from being applied to the hose.
[0010]
Since the belt-like sheet 12 has a sufficient length so as to cope with the increase in the hydraulic line 4 in advance, the hydraulic line 4 is composed of three hoses as shown in FIGS. If it is, an extra length is generated at the end portion 12a of the belt-like sheet. However, as shown in the drawing, the one end portion 12a is folded and overlapped with the other end portion 12a, so that the surplus amount becomes an obstacle. There is no.
[0011]
3 and 4, shows the hose clamp 11 when the hydraulic line 4 is increased, in the same manner as described above even in this case, the belt-like sheet 12 is curved in the longitudinal direction and surrounds the hydraulic line 4, the hydraulic line 4, the end portions 12 a of the belt-like sheet 12 are positioned so as to overlap each other, and a gap between a plurality of hoses constituting the hydraulic line 4 is formed from one side of the belt-like sheet 12 surrounding the hydraulic line 4. The binding wire 14 is penetrated to the other side of the belt-like sheet 12 and fixed . In this case, since the hydraulic line 4 is increased and the number of hoses is increased, no excessive length is generated at the end 12a of the belt-like sheet 12 . Thus, even when the hydraulic line 4 is increased, the hydraulic line 4 can be bundled with the same belt-like sheet 12, and the operation is extremely easy.
[0012]
It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
[0013]
【The invention's effect】
As described in detail in the above embodiment, the invention according to the first aspect of the present invention is such that a hose clamp is formed by a flexible strip-shaped sheet, and a through hole for a binding wire is appropriately formed in the strip-shaped sheet. Since the holes are opened at intervals , it is possible to cope with the increase or decrease of the hydraulic line with one kind of hose clamp by selecting an arbitrary hole and penetrating the binding wire. Further, when the belt-like sheet is curved in the longitudinal direction to surround the hydraulic line, the binding line penetrates from the one side of the belt-like sheet surrounding the hydraulic line to the other side of the belt-like sheet by sewing the interval between the hydraulic lines. The belt-like sheet is fixed to the hose at the center and the belt-like sheet is fastened with a binding wire so that a gap is formed between the hose other than the hose at the center and the belt-like sheet. By sliding, it is possible to prevent excessive force from being applied to each hose.
