Description
【０００１】[0001]
本考案は、管路に発生した変形を補修する装置に関するものである。 The present invention relates to a device for repairing a deformation that has occurred in a pipeline.
【０００２】[0002]
地中等に埋設してある電線管や水道管等は、地上を走行する大型車両等の重圧 による土圧で部分的に変形することがあり、この変形不良管を交換している。 Conduit pipes and water pipes buried in the ground etc. may be partially deformed by the earth pressure due to the heavy pressure of large vehicles traveling on the ground, and this defective pipe is replaced.
【０００３】[0003]
地中等に埋設してある電線管や水道管が変形した場合に、その変形不良管を交 換するには、掘り起こしや、管の切断、接続及び埋め戻し等の面倒な作業を必要 としている。殊に電線管や水道管等では交換作業には短時間が要求されるが、上 記のような作業では時間がかかり、このような管の変形を短時間で行うことが課 題になっている。 When a conduit or water pipe buried in the ground is deformed, replacing the defective pipe requires complicated work such as dug up, cutting, connecting and backfilling. Especially for conduits and water pipes, a short time is required for the replacement work, but the work described above takes time, and it is an issue to perform such pipe deformation in a short time. There is.
【０００４】 本考案の目的は、上記従来の課題を解決した管の変形補修装置を提供すること である。An object of the present invention is to provide a pipe deformation / repair device that solves the above-mentioned conventional problems.
【０００５】[0005]
上記の目的を達成するための本考案の要旨は、円周上で複数に分割した円筒状 のドラムと、このドラム内に設置した油圧シリンダと、この油圧シリンダによっ てドラムの軸線方向に進退移動し、前記ドラムの内周面とテーパ対接してドラム を径方向に拡開するテーパコーンとを備えたものである。 The gist of the present invention for achieving the above object is to divide a cylinder into a plurality of cylindrical drums, a hydraulic cylinder installed in the drum, and a forward / backward movement in the axial direction of the drum by the hydraulic cylinder. A taper cone that moves and expands the drum in the radial direction by being in taper contact with the inner peripheral surface of the drum.
【０００６】[0006]
上記の構成により、ドラムを管の変形部位まで挿入し、油圧シリンダによって テーパコーンを前進移動させることにより、複数に分割されているドラムが径方 向に拡開し、このドラムの拡開力によって管の変形部を押し拡げて正規の形状に 修復する。 With the above configuration, the drum is inserted into the deformed portion of the pipe, and the taper cone is moved forward by the hydraulic cylinder, whereby the drum divided into multiple parts expands radially, and the expansion force of this drum expands the pipe. The deformed part of is expanded and restored to the regular shape.
【０００７】[0007]
以下本考案の実施例を図面に基づいて説明する。図１において、１は円筒状の ドラムであり、図２及び図３で示すように、円周上で複数に分割され、各分割間 をスプリング６で連結している。 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a cylindrical drum, which is divided into a plurality of pieces on the circumference as shown in FIGS. 2 and 3, and each division is connected by a spring 6.
【０００８】 前記ドラム１内には油圧シリンダ２がドラム１の軸線方向に設置されている。 この油圧シリンダ２内には２つのピストンが嵌装され、このそれぞれのピストン にロッド４ａ，４ｂを介してテーパコーン３ａ，３ｂが結合されている。A hydraulic cylinder 2 is installed in the drum 1 in the axial direction of the drum 1. Two pistons are fitted in the hydraulic cylinder 2, and taper cones 3a and 3b are connected to the respective pistons via rods 4a and 4b.
【０００９】 前記テーパコーン３ａ，３ｂは、前記ドラム１の内周面に形成されたテーパ面 ５ａ，５ｂに対接し、テーパコーンの前進移動によりドラム１を径方向に拡開す る。前記スプリング６は、この拡開したドラム１を縮径する。The taper cones 3 a and 3 b are in contact with the taper surfaces 5 a and 5 b formed on the inner peripheral surface of the drum 1, and the drum 1 is expanded in the radial direction by the forward movement of the taper cone. The spring 6 reduces the diameter of the expanded drum 1.
【００１０】 ７は前記油圧シリンダ２に油圧を給排する油圧ホースである。８はアイボルト であり、図４及び図５で示すようにロープが結合される。Reference numeral 7 is a hydraulic hose for supplying and discharging hydraulic pressure to and from the hydraulic cylinder 2. Reference numeral 8 is an eyebolt, to which a rope is coupled as shown in FIGS. 4 and 5.
【００１１】 本考案は上記の通りの構造であるから、図４で示すように、管１０の一部に凹 み１１の変形が生じた場合、アイボルト８にロープ９を結合したドラム１を縮径 状態で管１０に挿入し、ロープ９でドラム１を引き動かして凹み１１の部位に位 置する。Since the present invention has the above-described structure, as shown in FIG. 4, when the recess 11 is partially deformed in the tube 10, the drum 1 in which the rope 9 is connected to the eyebolt 8 is compressed. The tube is inserted into the tube 10 in a diameter state, and the drum 1 is pulled by the rope 9 to move it to the position of the recess 11.
【００１２】 その後、油圧シリンダ２に油圧を供給してテーパコーン３ａ，３ｂを前進移動 する。これにより、テーパコーン３ａ，３ｂはドラム１の内周面のテーパ面５ａ ，５ｂを摺動し、いわゆる楔作用によって、テーパコーン３ａ，３ｂの軸線方向 の推力をドラム１の径方向に変換伝達し、複数に分割されたドラム１を径方向に 拡開する。After that, hydraulic pressure is supplied to the hydraulic cylinder 2 to move the taper cones 3a and 3b forward. As a result, the taper cones 3a and 3b slide on the taper surfaces 5a and 5b of the inner peripheral surface of the drum 1, and by a so-called wedge action, the thrust in the axial direction of the taper cones 3a and 3b is converted and transmitted in the radial direction of the drum 1, The drum 1 divided into a plurality is expanded in the radial direction.
【００１３】 このドラム１の拡開によって、前記管１０の凹み１１が押し広げられ、図５で 示すように管１０は凹み１１の変形が修復されて正規の形状に復元される。By the expansion of the drum 1, the recess 11 of the pipe 10 is expanded and the pipe 10 is restored to the normal shape by repairing the deformation of the recess 11 as shown in FIG.
【００１４】 前記管１０の凹み１１が修復された後には、油圧シリンダ２の油圧を排出する ことにより、拡開していたドラム１はスプリング６によって縮径され、管１０か ら抜き取る。After the recess 11 of the pipe 10 is repaired, the hydraulic pressure of the hydraulic cylinder 2 is discharged, so that the expanded drum 1 is contracted by the spring 6 and pulled out from the pipe 10.
【００１５】[0015]
以上のように本考案によると、円周上で複数に分割した円筒状のドラムと、こ のドラム内に設置した油圧シリンダと、この油圧シリンダによってドラムの軸線 方向に進退移動し、前記ドラムの内周面とテーパ対接してドラムを径方向に拡開 するテーパコーンとを備えた構成であるから、地中等に埋設してある電線管や水 道管の凹み変形を短時間で補修することができ、従来のように地面等の掘り起こ し、管の切断、接続及び埋め戻し等の面倒な作業を行う必要がなくなる。 As described above, according to the present invention, a cylindrical drum divided into a plurality of parts on the circumference, a hydraulic cylinder installed in the drum, and a forward / backward movement in the axial direction of the drum by the hydraulic cylinder, Since it is equipped with a taper cone that tapers the inner peripheral surface and expands the drum in the radial direction, it is possible to repair the dent deformation of the conduit tube or the water tube buried in the ground in a short time. Therefore, it is not necessary to dig up the ground or the like and perform the troublesome work such as cutting, connecting and backfilling the pipe as in the conventional case.
