Description

  The present invention relates to a hose restraint tool and a hose with a restraint tool.

  Conventionally, a construction method is known in which concrete or steel bars are cut using a high-pressure fluid, or old paint is peeled off. Such a construction method is carried out by connecting one or more hoses capable of withstanding high pressure between the apparatus for generating high-pressure fluid and the work place, and ejecting the high-pressure fluid from the nozzle at the tip of the hose.

However, if the connection between the hose and the hose and the connection between the high-pressure fluid generator and the hose are damaged due to fatigue due to long-term use and the connection state of the hose is released, the reaction force of the pressure The internal fluid is sprinkled around while the edges are violent.
For this reason, in Patent Documents 1 and 2, a restraint is attached in the vicinity of the end of the hose, and a connecting member such as a chain provided in the restraint is attached to a fixed object to be attached. By connecting the objects to be attached, the end of the hose whose connected state has been released is prevented from being ramped up.

And the above-mentioned ring part 27 is formed in the front end side of each extension part 26B.

Next, an example of a procedure for attaching the hose restraint 20 to the hose 14 will be described.
First, the hose 14 is inserted into the in-cylinder hollow 22S from one end side of the cylindrical member 22 in the cylinder axis direction. Then, a plurality (two in this embodiment) of the split pieces 24 are arranged on the outer periphery of the hose 14 at intervals in the circumferential direction Y, and the clamping member 25 is configured on the outer periphery of the hose 14 (see FIG. 3). Here, it is preferable that the position where the clamping member 25 (divided piece 24) is arranged is in the vicinity of the end portion 14E of the hose 14. In the present embodiment, the clamping member 25 (divided piece 24) is arranged so that the distance L between the end portion 14E and the other end of the clamping member 25 (divided piece 24) in the cylinder axis direction is within 10 cm. is doing.

  Next, the central portion in the longitudinal direction of the connecting cord member 26 is hooked on one end portion 24X of one divided piece 24, and both outer portions in the longitudinal direction from the central portion are between the circumferential end portions 24Y of the adjacent divided pieces 24. Pass through.

Then, the cylindrical member 22 is slid along the hose 14 so that the clamping member 25 is inserted into the in-cylinder hollow 22S from the other end side in the cylinder axis direction. Here, as described above, since the outer peripheral wall 25A of the clamping member 25 is shaped along the inner peripheral wall 22B of the cylindrical member 22, the cylindrical member 22 is moved from the other end side in the cylinder axis direction. It becomes easy to insert into the hollow 22S in the cylinder. Thereby, the attachment work to the hose 14 of the hose restraint tool 20 becomes easy.
The sandwiching member 25 is inserted into the cylindrical member 22 until the center portion in the longitudinal direction of the connecting cord member 26 is sandwiched between the one end portion 25X and the inner extending portion 23. Thereby, the 1st to-be-clamped part 26A, the extension part 26B, and the 2nd to-be-clamped part 26C of the connection cord member 26 are comprised.

Thereafter, by clamping the cylindrical member 22, the clamping member 25 is crimped together with the cylindrical member 22, and the cylindrical member 22 and the clamping member 25 are attached to the hose 14. Accordingly, the first sandwiched portion 26 </ b> A sandwiched between the circumferential end portions 24 </ b> Y of the adjacent divided pieces 24 is attached to the hose 14 via the sandwiching member 25.
In this way, the hose 28 with restraint device to which the hose restraint device 20 is attached is configured.

Moreover, since the hose restraint tool 20 is attached to the hose 14 by crimping the clamping member 25 together with the cylindrical member 22, for example, the thickness of a part of the restraint tool is made thicker than the other parts. The thickness can be made to be uniform compared with the case where the bolt is fixed (see FIG. 4).
Furthermore, the hose restraining tool 20 is clamped by the clamping member 25 arranged along the inner periphery of the cylindrical member 22, for example, the outer periphery of the cylindrical member 22. The thickness can be made closer to that of the wall 22 </ b> A compared to the case in which the projection for attaching the connecting member is provided on the wall 22 </ b> A.
As described above, according to the hose restraint 20, since the thickness can be made closer to that of the conventional one, the winding operation of the hose 14 in the hose-mounted state can be facilitated and the wound hose 14 can be easily wound. It is possible to suppress the occurrence of problems such as damage by suppressing the local application of load.

  Moreover, in this embodiment, since the hose restraint tool 20 is arrange | positioned in the vicinity of the edge part 14E of the hose 14 (position where the distance L is less than 10 cm), rampage of the edge part 14E of the hose 14 is more effectively performed. It is suppressed. And the winding operation | work can be made easier by arrange | positioning the hose restraint tool 20 to the edge part 14E vicinity of the hose 14. FIG.
