Description
本考案は、特に構成がシンプルで使用上に利便性が高いネジ用エキストラクターに関するものである。 The present invention relates to a screw extractor that has a particularly simple structure and is highly convenient to use.
既存のボルトは、ネジ部を備える連接または締付け用の結合部材であり、簡単に取り付けたり取り外したりすることができると共に、捻じ込み操作により締め付ける程度を調整できることから、機械の結合や、建築の組み立てに使用されている。また、ボルトを締付ける過程において、捻じ込みすぎると、ボルトが折れる虞があり、折れてしまうと、ボルトまたはそのネジ部が物体の穴の中に残ってしまうことから、折れたボルトを取り出すことができないという問題があった。 Existing bolts are connecting or tightening coupling members with threaded parts, and can be easily attached and removed, and the degree of tightening can be adjusted by a screwing operation. Is used. Also, in the process of tightening the bolt, if the screw is tightened too much, the bolt may be broken, and if it is broken, the bolt or its screw part will remain in the hole of the object, so that the broken bolt can be taken out. There was a problem that I could not.
前記既存のボルトの残骸を取り除く方法としては、以下の３つがある。
方法一：鋭い棒を用いて折れたボルトに当接させながら叩き、折れたボルトを取り出す。しかし、この方法は、ボルトが穴の浅い所に残った場合にしか利用できないと共に、取り除き作業にかなりの時間及び労力を必要とし、穴のネジ山にも傷を付けてしまうという問題があった。
方法二：折れたボルトをアルゴン溶接などの溶接手段で他の棒体に溶接して、棒体と共に取り出す。しかし、この方法は、方法一と同様にボルトが穴の浅い所に残った場合にしか利用できなく、また、溶接作業が難しく、作業コストが高いという問題があった。
方法三：折れたボルトを抜き出し装置を利用して折れたボルトを取り出す。
There are the following three methods for removing the existing bolt debris.
Method 1: Use a sharp stick to strike the broken bolt against the broken bolt and take out the broken bolt. However, this method has a problem that it can be used only when the bolt remains in the shallow part of the hole, and requires a considerable time and labor for the removal work, and also damages the screw thread of the hole. .
Method 2: The broken bolt is welded to another rod body by welding means such as argon welding and taken out together with the rod body. However, this method can be used only when the bolt remains in a shallow hole as in Method 1, and there is a problem that the welding operation is difficult and the operation cost is high.
Method 3: Take out the broken bolt using a device.
既存の折れたボルトの取り出し装置は、例えば、台湾特許公告第１６３１６４号及び、台湾実用新案第Ｍ２９０４５２号に開示されている。図７に示すように、既存の取り出し装置９０は、細長状の棒体を有し、該棒体の一端に、円錐状かつネジ山を有する締め頭部９１が設けられると共に、他端に六角形の連結部が凹設され、該連結部に補助工具が挿設され、補助工具を回して取出し装置９０を駆動すると、折れたボルトを取り出すことができる。例えば、図７に示すように、そのボルト６０が折れて物体５０のねじ穴５１内に残った場合は、まずドリル８０を用いて、折れたボルト６０の端面の中心に穴６１を開け、取り出し装置９０の締め頭部９１をボルト６０の穴６１に捻じ込み、この時、締め頭部９１にあるネジ山は、ボルト６０のネジ山と異なる方向であるため、取り出し装置９０を締め頭部９１を介して穴６１に捻じ込むと、ボルト６０が同期的に回転するので、物５０のねじ穴５１から取り出すことができる。 Existing broken bolt take-out devices are disclosed in, for example, Taiwan Patent Publication No. 163164 and Taiwan Utility Model No. M290454. As shown in FIG. 7, an existing take-out device 90 has an elongated rod body, and a conical and threaded fastening head 91 is provided at one end of the rod body, and a hexagonal head is provided at the other end. A rectangular connecting portion is recessed, and an auxiliary tool is inserted into the connecting portion. When the auxiliary tool is turned to drive the take-out device 90, the broken bolt can be taken out. For example, as shown in FIG. 7, when the bolt 60 is broken and remains in the screw hole 51 of the object 50, first, using the drill 80, a hole 61 is opened at the center of the end surface of the broken bolt 60 and taken out. The fastening head 91 of the device 90 is screwed into the hole 61 of the bolt 60. At this time, the thread on the fastening head 91 is in a different direction from the thread of the bolt 60. When the screw 60 is screwed into the hole 61, the bolt 60 rotates synchronously, so that it can be taken out from the screw hole 51 of the object 50.
しかしながら、既存の取り出し装置を用いれば、折れたボルトを物のねじ穴から取り出すことはできるが、取り出し装置を使用する前に、ボルトの折れた端面に、穴を開ける必要があることから、操作上非常に面倒であり、ドリルなどの切削工具を利用する必要があるので、狭い現場では操作が困難であった。 However, if the existing take-out device is used, the broken bolt can be taken out from the screw hole of the object, but before using the take-out device, it is necessary to make a hole in the broken end surface of the bolt. In addition, it is very troublesome, and it is necessary to use a cutting tool such as a drill.
本考案に係るネジ用エキストラクターは、柱状を呈するネジロッドと、該ネジロッドの外周面に形成されるネジ山と、該ネジロッドの一端に形成される少なくとも１つの爪刃と、該ネジロッドの他端に形成される駆動部とを有する。 A screw extractor according to the present invention includes a screw rod having a columnar shape, a thread formed on an outer peripheral surface of the screw rod, at least one claw blade formed on one end of the screw rod, and the other end of the screw rod. And a drive unit to be formed.
かかるネジ用エキストラクターにおいて、前記ネジロッドに、３つの爪刃が等間隔で環状に配列されることが好ましい。 In such a screw extractor, it is preferable that three claw blades are annularly arranged at equal intervals on the screw rod.
かかるネジ用エキストラクターにおいて、前記駆動部が非円形の凹部であることが好ましい。 In such a screw extractor, it is preferable that the drive unit is a non-circular recess.
かかるネジ用エキストラクターにおいて、前記駆動部が六角形の凹部であることが好ましい。 In such a screw extractor, the drive unit is preferably a hexagonal recess.
かかるネジ用エキストラクターにおいて、前記駆動部に対応する、駆動頭部及び連結部を備える連接棒を有することが好ましい。 In such a screw extractor, it is preferable to have a connecting rod provided with a driving head and a connecting portion corresponding to the driving portion.
