Description
本発明は、取付対象物を取付相手に取り付けるための取付対象物取付治具に関する。
The present invention relates to a mounting object mounting jig for mounting a mounting object to a mounting partner.
測定器などの取付対象物を測定期間中において一時的に測定対象の底面等に取り付けることがある。測定器の取付にあっては、測定器を作業者自らの手で把持して行う方法や、棒状工具の先端に取り付けたヤットコ等の把持用工具で把持して行う方法などがある。また、測定器を測定対象に密着して取り付けておくために、測定器側に設けた吸盤の吸着力や磁石の磁力を利用する場合がある。
取 付 Attachment objects such as measuring instruments may be temporarily attached to the bottom surface of the measurement object during the measurement period. In attaching the measuring instrument, there are a method in which the measuring instrument is gripped by the operator's own hand, a method in which the measuring instrument is gripped with a gripping tool such as a hook attached to the tip of the rod-shaped tool, and the like. In addition, in order to attach the measuring instrument in close contact with the object to be measured, the suction force of a suction cup provided on the measuring instrument side or the magnetic force of a magnet may be used.
なお、特許文献１には、支柱ホルダーを同一位置に保ったまま回動できる支柱支持具が開示されている。
Note that Patent Document 1 discloses a column support that can be rotated while maintaining the column holder in the same position.
作業者自らの手で測定器を把持する方法や、把持用工具で把持する方法を採用した場合、作業者の負担が高く、疲労の原因にもなる。また、この疲労のために作業者に手の震えやブレが生じ、この振動が測定器に伝達されて、測定精度に影響を与えるおそれもある。また、前述の吸盤等の取付補助具を用いる場合において、取付対象物が取付相手から外れてしまったときの落下を防止しなければならない。
When the method of gripping the measuring instrument with the operator's own hand or the method of gripping with the gripping tool is adopted, the burden on the worker is high and also causes fatigue. In addition, the operator may shake hands and shake due to this fatigue, and this vibration may be transmitted to the measuring instrument, affecting the measurement accuracy. In addition, in the case of using the above-described attachment aid such as a suction cup, it is necessary to prevent a drop when the attachment object is detached from the attachment counterpart.
よって、測定器などの取付対象物を取付相手に取り付けようとする際に確実に取付対象物を保持することができ、取付後においては作業者等からの外力が取付対象物に伝達されにくいことが望まれる。また、取付補助具を用いているにもかかわらず取付対象物が取付相手から外れてしまった場合には、取付対象物が落下しないようにすることが望まれる。
Therefore, when mounting an object such as a measuring instrument to the mounting partner, the mounting object can be securely held, and external force from the operator or the like is not easily transmitted to the mounting object after mounting. Is desired. In addition, it is desired that the attachment object does not fall when the attachment object is detached from the attachment partner even though the attachment aid is used.
本発明は、このような事情に鑑みてなされたものであり、その目的は、取付対象物を取付相手に取り付けようとする際に確実に取付対象物を保持することができ、取付後においては作業者等からの外力が取付対象物に伝達されにくいようにすることができる一方、取付対象物が取付相手から外れてしまった場合には、取付対象物が落下しないようにする取付対象物取付治具を提供することにある。
The present invention has been made in view of such circumstances, and the purpose of the present invention is to reliably hold the mounting object when attempting to mount the mounting object on the mounting partner. While it is possible to make it difficult for external forces from workers to be transmitted to the mounting target, the mounting target mounting prevents the mounting target from dropping if the mounting target is removed from the mounting partner. To provide a jig.
前述の目的を達成するため、本発明は、取付対象物取付治具であって、一端側に取付対象物が保持される棒状部材と、前記棒状部材の他端側を軸方向に挿入可能な筒状部材と、を備え、前記棒状部材の前記他端の前記筒状部材に挿入される部分には、前記棒状部材の軸に交差する方向に貫通する貫通孔が設けられ、前記筒状部材の前記棒状部材が挿入される側の端部には、前記貫通孔を挿通する挿通部材が設けられ、前記貫通孔は、前記挿通部材の太さよりも広い開口を有することを特徴とする。
In order to achieve the above-mentioned object, the present invention is a mounting object mounting jig, in which a rod-shaped member that holds the mounting object on one end side and the other end side of the rod-shaped member can be inserted in the axial direction. A through-hole penetrating in a direction intersecting the axis of the rod-shaped member is provided in a portion inserted into the cylindrical member at the other end of the rod-shaped member. An insertion member for inserting the through hole is provided at an end portion on the side where the rod-shaped member is inserted, and the through hole has an opening wider than the thickness of the insertion member.
本発明の取付対象物取付治具によれば、取付対象物を取付相手に取り付ける際には、棒状部材を筒状部材に挿入した状態とすることで、筒状部材に対する棒状部材の移動が拘束される。これにより、筒状部材を把持する作業者により確実に取付対象物を取付相手に接触させることができる。また、取付対象物を取付相手に取り付けた後においては、棒状部材から筒状部材を引き抜くことで、棒状部材に対する筒状部材の拘束を解除することができる。このとき、貫通孔は挿通部材の太さよりも広い開口を有することから、被挿入部材の変位を棒状部材に伝達しにくくすることができる。また、このような状況下で、仮に、取付対象物が取付相手から外れた場合であっても、挿通部材が貫通孔に挿通していることから、棒状部材は被挿入部材に連結されたままである。よって、棒状部材に固定された取付対象物が落下するのを防止することができる。
According to the mounting object mounting jig of the present invention, when the mounting object is mounted on the mounting partner, the rod-shaped member is inserted into the cylindrical member so that the movement of the rod-shaped member with respect to the cylindrical member is restrained. Is done. Thereby, the attachment object can be made to contact an attachment other party reliably by the operator who holds the cylindrical member. In addition, after the attachment object is attached to the attachment counterpart, the restriction of the tubular member with respect to the rod-shaped member can be released by pulling the tubular member out of the rod-shaped member. At this time, since the through-hole has an opening wider than the thickness of the insertion member, it is possible to make it difficult to transmit the displacement of the inserted member to the rod-shaped member. Further, under such circumstances, even if the attachment object is removed from the attachment counterpart, since the insertion member is inserted through the through hole, the rod-like member remains connected to the inserted member. is there. Therefore, it can prevent that the attachment target fixed to the rod-shaped member falls.
すなわち、取付対象物を取付相手に取り付けようとする際に確実に取付対象物を保持することができ、取付後においては作業者等からの外力が取付対象物に伝達されにくくすることができる一方、取付対象物が取付相手から外れてしまった場合には、取付対象物が落下しないようにする取付対象物取付治具を提供することができる。
That is, the attachment object can be reliably held when attempting to attach the attachment object to the attachment partner, and it is possible to make it difficult for external force from the operator or the like to be transmitted to the attachment object after the attachment. When the attachment object has come off the attachment counterpart, it is possible to provide an attachment object attachment jig that prevents the attachment object from falling.
前述の取付対象物取付治具において、前記筒状部材の前記棒状部材が挿入される側の端部には、前記筒状部材の軸方向に突出する少なくとも２つの突出部を有し、前記挿通部材は、前記突出部間に掛け渡され、前記貫通孔を挿通することが好ましい。
In the above-described mounting object mounting jig, the end of the tubular member on the side where the rod-shaped member is inserted has at least two projecting portions projecting in the axial direction of the tubular member, and the insertion member It is preferable that the member is stretched between the protruding portions and inserted through the through hole.
このようにすることで、挿通部材は突出部により筒状部材から突出することになるので、貫通孔に対する挿通部材の移動の自由度を高めることができる。また、より大きく棒状部材から筒状部材を引き抜いた状態でも両者の連結状態を維持することができる。そして、作業者が筒状部材の位置をより大きく変位させてしまう場合であっても棒状部材にその変位による外力を伝達しにくくすることができる。
By doing in this way, since the insertion member protrudes from the cylindrical member by the protruding portion, the degree of freedom of movement of the insertion member relative to the through hole can be increased. Further, even when the cylindrical member is pulled out from the rod-shaped member larger, the connection state between the two can be maintained. And even if it is a case where an operator displaces the position of a cylindrical member largely, it can make it difficult to transmit the external force by the displacement to a rod-shaped member.
前述の取付対象物取付治具において、前記貫通孔は、前記棒状部材の軸に交差する方向に貫通する第１貫通孔であって、前記棒状部材の軸方向に長い第１貫通孔と、前記棒状部材の軸に交差する方向に貫通し、前記棒状部材の前記他端側から前記第１貫通孔に接続する第２貫通孔であって、前記第１貫通孔の孔幅よりも広い孔幅を有する第２貫通孔と、を備え、前記棒状部材を前記筒状部材に挿入するときにおいて、前記第１貫通孔は前記挿通部材を前記棒状部材の軸方向に案内することが好ましい。
In the above-described mounting object mounting jig, the through-hole is a first through-hole penetrating in a direction intersecting the axis of the rod-shaped member, the first through-hole being long in the axial direction of the rod-shaped member, A second through-hole penetrating in a direction intersecting the axis of the rod-shaped member and connected to the first through-hole from the other end side of the rod-shaped member, and having a hole width wider than the hole width of the first through-hole When the rod-shaped member is inserted into the cylindrical member, the first through-hole preferably guides the insertion member in the axial direction of the rod-shaped member.
このようにすることで、棒状部材を筒状部材に挿入するときにおいて、第１貫通孔に挿通部材が通りその移動経路を案内することにより、棒状部材をより容易に筒状部材に挿入することができる。また、第２貫通孔は第１貫通孔よりも広い孔幅を有することから、筒状部材が棒状部材から引き抜かれているときにおいて、第２貫通孔において挿通部材を接触しにくくすることができる。そして、作業者が被挿入部材の位置をより大きく変位させてしまう場合であっても棒状部材にその変位による外力を伝達しにくくすることができる。
Thus, when the rod-shaped member is inserted into the cylindrical member, the rod-shaped member can be more easily inserted into the cylindrical member by guiding the moving path through the first through hole. Can do. In addition, since the second through hole has a wider hole width than the first through hole, it is possible to make the insertion member difficult to contact in the second through hole when the cylindrical member is pulled out from the rod-like member. . And even if it is a case where an operator displaces the position of a member to be inserted more largely, it can make it difficult to transmit external force by the displacement to a rod-shaped member.
前述の取付対象物取付治具において、前記貫通孔において、前記第１貫通孔の孔幅から前記第２貫通孔の孔幅に遷移するための傾斜部を有することが好ましい。
In the above-described mounting object mounting jig, it is preferable that the through hole has an inclined portion for making a transition from the hole width of the first through hole to the hole width of the second through hole.
このようにすることで、挿通部材が第２貫通孔から第１貫通孔に移動する際に、傾斜部を摺動することができるので、挿通部材の移動を行いやすくすることができる。これにより、第１貫通孔に挿通部材が通りやすくなるため、棒状部材をより容易に被挿入部材に挿入することができる。
By doing in this way, when the insertion member moves from the second through hole to the first through hole, the inclined portion can be slid, so that the insertion member can be easily moved. Thereby, since the insertion member can easily pass through the first through hole, the rod-like member can be more easily inserted into the member to be inserted.
前述の取付対象物取付治具において、前記棒状部材の前記他端の外形形状は半球形状を有することが好ましい。
In the above-described mounting object mounting jig, the outer shape of the other end of the bar-shaped member preferably has a hemispherical shape.
このように、端部の外形形状が半球形状であるので、棒状部材が外筒部材に対して挿通部材を軸として回転する場合において、棒状部材の挿入される側の端部が筒状部材の端部に掛かりにくくすることができる。そのため、作業者が筒状部材の位置について挿通部材を軸として回転させるような変位を生じさせた場合であっても、棒状部材にその変位による外力を伝達しにくくすることができる。
Thus, since the outer shape of the end portion is hemispherical, when the rod-shaped member rotates about the insertion member with respect to the outer cylindrical member, the end portion on the side where the rod-shaped member is inserted is the cylindrical member. It is possible to make it difficult to hang on the end. Therefore, even if the worker causes a displacement that rotates the insertion member about the position of the cylindrical member as an axis, it is difficult to transmit an external force due to the displacement to the rod-shaped member.
前述の取付対象物取付治具において、前記棒状部材の前記他端の外周形状及び前記筒状部材の前記棒状部材が挿入される端部の外周形状は、ともに円筒形状を有することが好ましい。
In the above-described mounting object mounting jig, it is preferable that both the outer peripheral shape of the other end of the rod-shaped member and the outer peripheral shape of the end portion of the cylindrical member into which the rod-shaped member is inserted have a cylindrical shape.
このようにすることで、円筒形状の棒状部材が円筒形状の筒状部材に挿入されることになるので、挿入の際において長手方向を軸とした回転を若干ながら許容することができる。そして、挿入をより容易にし、作業性を向上させることができる。
By doing so, since the cylindrical rod-shaped member is inserted into the cylindrical tubular member, the rotation around the longitudinal direction can be allowed while being inserted. And insertion can be made easier and workability | operativity can be improved.
前述の取付対象物取付治具において、前記棒状部材の前記一端側に自在継手が取り付けられ、前記棒状部材は前記自在継手を介して前記取付対象物を保持することが好ましい。
In the above-described mounting object mounting jig, a universal joint is preferably attached to the one end side of the rod-shaped member, and the rod-shaped member holds the mounting object via the universal joint.
このようにすることで、自在継手によって棒状部材と取付対象物との間の角度を可変にすることができるので、取付対象物を所定の角度に傾けた状態で取付相手に取り付けることができる。
By doing in this way, the angle between the rod-shaped member and the object to be attached can be made variable by the universal joint, so that the object to be attached can be attached to the attachment partner in a state of being inclined at a predetermined angle.
前述の取付対象物取付治具において、前記被挿入部材にグリップを設けることが好ましい。
In the above-described mounting object mounting jig, it is preferable to provide a grip on the inserted member.
このようにすることで、作業者は被挿入部材を把持しやすくなるため、作業性を向上させることができる。
This makes it easier for the operator to grip the member to be inserted, thus improving workability.
前述の取付対象物取付治具において、前記筒状部材に当該筒状部材の長手方向に長さを延長する棒状工具を設けることを特徴とすることとしてもよい。
In the above-described mounting object mounting jig, the cylindrical member may be provided with a rod-shaped tool that extends in the longitudinal direction of the cylindrical member.
このようにすることで、作業者から取付相手が離れている場合においても、取付対象物を取付相手に取り付けることができる。
By doing in this way, even when the mounting partner is away from the operator, the mounting target can be mounted on the mounting partner.
本発明によれば、取付対象物を取付相手に取り付ける際には、棒状部材を被挿入部材に挿入した状態とすることで、被挿入部材に対する棒状部材の移動が拘束される。これにより、被挿入部材を把持する作業者により確実に取付対象物を取付相手に接触させることができる。また、取付対象物を取付相手に取り付けた後においては、棒状部材から被挿入部材を引き抜くことで、棒状部材に対する被挿入部材の拘束を解除することができる。このとき、貫通孔は挿通部材の太さよりも広い開口を有することから、被挿入部材の変位を棒状部材に伝達しにくくすることができる。また、このような状況下で、仮に、取付対象物が取付相手から外れた場合であっても、挿通部材が貫通孔に挿通していることから、棒状部材は被挿入部材に連結されたままである。よって、棒状部材に固定された取付対象物が落下するのを防止することができる。すなわち、取付対象物を取付相手に取り付けようとする際に確実に取付対象物を保持することができ、取付後においては作業者等からの外力が取付対象物に伝達されにくくすることができる一方、取付対象物が取付相手から外れてしまった場合には、取付対象物が落下しないようにする取付対象物取付治具を提供することができる。
According to the present invention, when the attachment object is attached to the attachment counterpart, the movement of the rod-shaped member relative to the member to be inserted is restrained by setting the rod-shaped member to be inserted into the member to be inserted. Thereby, the attachment object can be made to contact an attachment other party reliably by the operator holding the member to be inserted. Further, after the attachment object is attached to the attachment counterpart, the restriction of the inserted member with respect to the rod-shaped member can be released by pulling out the inserted member from the rod-shaped member. At this time, since the through hole has an opening wider than the thickness of the insertion member, it is possible to make it difficult to transmit the displacement of the inserted member to the rod-shaped member. Further, under such circumstances, even if the attachment object is removed from the attachment counterpart, since the insertion member is inserted through the through hole, the rod-like member remains connected to the inserted member. is there. Therefore, it can prevent that the attachment target fixed to the rod-shaped member falls. That is, the attachment object can be reliably held when attempting to attach the attachment object to the attachment partner, and it is possible to make it difficult for external force from the operator or the like to be transmitted to the attachment object after the attachment. When the attachment object has come off the attachment counterpart, it is possible to provide an attachment object attachment jig that prevents the attachment object from falling.
図１は、心棒１１が外筒１２に挿入された状態における測定器取付治具１の正面図である。図２は、心棒１１が外筒１２から引き出された状態における測定器取付治具１の正面図である。以下、これらの図を参照しつつ、測定器取付治具１（取付対象物取付治具に相当）の構成について説明する。
FIG. 1 is a front view of the measuring instrument mounting jig 1 in a state where the mandrel 11 is inserted into the outer cylinder 12. FIG. 2 is a front view of the measuring instrument mounting jig 1 in a state where the mandrel 11 is pulled out from the outer cylinder 12. Hereinafter, the configuration of the measuring instrument mounting jig 1 (corresponding to the mounting object mounting jig) will be described with reference to these drawings.
測定器取付治具１は、心棒１１（棒状部材に相当）と、外筒１２（筒状部材に相当）と、心棒側継手部材１３と、グリップ１５と、連結ピン１２１（挿通部材に相当）を備える。
The measuring instrument mounting jig 1 includes a mandrel 11 (corresponding to a rod-like member), an outer cylinder 12 (corresponding to a tubular member), a mandrel-side joint member 13, a grip 15, and a connecting pin 121 (corresponding to an insertion member). Is provided.
心棒１１は、円筒形状の部材である。心棒１１は、外筒１２に挿入する挿入端１１ａと、後述する測定器２００が取り付けられる非挿入端１１ｂを有する。心棒１１の非挿入端１１ｂ側には、測定器２００を固定するための心棒側継手部材１３が設けられる。また、心棒１１の挿入端１１ａ側は、その先端外形が半球形状を有するように形成される。心棒１１と心棒側継手部材１３は、一体として射出成形することができる。
The mandrel 11 is a cylindrical member. The mandrel 11 has an insertion end 11a to be inserted into the outer cylinder 12, and a non-insertion end 11b to which a measuring instrument 200 described later is attached. A mandrel side joint member 13 for fixing the measuring device 200 is provided on the non-insertion end 11 b side of the mandrel 11. Further, the insertion end 11a side of the mandrel 11 is formed so that the tip outer shape has a hemispherical shape. The mandrel 11 and the mandrel side joint member 13 can be injection-molded as a single unit.
また、心棒１１には、直径方向に貫通する貫通孔１１１が設けられる。貫通孔１１１は、連結ピン摺動溝１１１ａと遊び空間１１１ｂを有する。連結ピン摺動溝１１１ａは、心棒１１の軸方向に長い貫通孔であって、連結ピン１２１の直径よりもわずかに大きい程度の孔幅（すなわち、連結ピン１２１が摺動移動可能な程度の孔幅）を有する貫通孔である。また、遊び空間１１１ｂは、連結ピン摺動溝１１１ａの幅よりも広い孔幅を有し、心棒１１の挿入端１１ａ側から連結ピン摺動溝１１１ａに接続する貫通孔である。遊び空間１１１ｂは、連結ピン１２１の直径よりも十分に広い開口を有する。
Further, the mandrel 11 is provided with a through hole 111 penetrating in the diameter direction. The through hole 111 has a connecting pin sliding groove 111a and a play space 111b. The connecting pin sliding groove 111a is a through hole that is long in the axial direction of the mandrel 11, and has a hole width that is slightly larger than the diameter of the connecting pin 121 (that is, a hole that allows the connecting pin 121 to slide and move). (Width). The play space 111b is a through hole having a hole width wider than the width of the connecting pin sliding groove 111a and connected to the connecting pin sliding groove 111a from the insertion end 11a side of the mandrel 11. The play space 111 b has an opening that is sufficiently wider than the diameter of the connecting pin 121.
連結ピン摺動溝１１１ａと遊び空間１１１ｂは、互いにその孔幅が異なることから、連結ピン摺動溝１１１ａの孔幅から遊び空間１１１ｂの孔幅に遷移するための傾斜部１１３を有する。そして、心棒１１を外筒１２に挿入するときにおいて、連結ピン摺動溝１１１ａは、連結ピン１２１を心棒１１の軸方向に案内する。
Since the connecting pin sliding groove 111a and the play space 111b have different hole widths, the connecting pin sliding groove 111a and the play space 111b have an inclined portion 113 for transition from the hole width of the connecting pin sliding groove 111a to the hole width of the play space 111b. When the mandrel 11 is inserted into the outer cylinder 12, the connecting pin sliding groove 111 a guides the connecting pin 121 in the axial direction of the mandrel 11.
外筒１２は、その内部を中空とした円筒形状の部材である。外筒１２は、心棒１１が挿入される被挿入端１２ａと、グリップ１５が取り付けられるグリップ端１２ｂを有する。外筒１２の被挿入端１２ａには、外筒１２の軸方向に突出する突出部１２４が対向して２つ設けられる。
The outer cylinder 12 is a cylindrical member having a hollow inside. The outer cylinder 12 has an inserted end 12a into which the mandrel 11 is inserted and a grip end 12b to which the grip 15 is attached. Two protruding portions 124 protruding in the axial direction of the outer cylinder 12 are provided on the insertion end 12 a of the outer cylinder 12 so as to face each other.
突出部１２４は、略三角形状を有しており、その三角形状のほぼ中心に貫通孔を有する。そして、これらの突出部１２４に掛け渡されるように連結ピン１２１としてのボルトが貫通孔と座金１２３を挿通し、ナット１２２に螺合される。連結ピン１２１は、心棒１１における貫通孔１１１を挿通する。なお、本実施形態において突出部１２４は略三角形状としたが、形状はこれに限られず、半円形状であったり台形形状であってもよい。
The projecting portion 124 has a substantially triangular shape, and has a through hole at substantially the center of the triangular shape. Then, a bolt as the connecting pin 121 is inserted through the through hole and the washer 123 so as to be spanned over the protrusions 124 and screwed into the nut 122. The connecting pin 121 is inserted through the through hole 111 in the mandrel 11. In the present embodiment, the protruding portion 124 has a substantially triangular shape, but the shape is not limited to this, and may be a semicircular shape or a trapezoidal shape.
また、心棒１１において、挿入端１１ａの先端から遊び空間１１１ｂの縁までの距離が短く構成されている。また、突出部１２４により連結ピン１２１を外筒１２の被挿入端１２ａよりも突出した位置に設けることを可能としている。このため、心棒１１から外筒１２が引き抜かれた状態において、心棒１１の挿入端１１ａが外筒１２の被挿入端１２ａに接触しにくい構成となっている。
Further, in the mandrel 11, the distance from the tip of the insertion end 11a to the edge of the play space 111b is configured to be short. Further, the connecting pin 121 can be provided at a position protruding from the insertion end 12 a of the outer cylinder 12 by the protruding portion 124. For this reason, in a state where the outer cylinder 12 is pulled out from the mandrel 11, the insertion end 11 a of the mandrel 11 is difficult to contact the inserted end 12 a of the outer cylinder 12.
外筒１２は、外筒側継手部材１４を備える。外筒１２と外筒側継手部材１４は、一体として射出成形することができる。また、グリップ１５は、グリップ側継手部材１５１を備える。グリップ側継手部材１５１は、外筒側継手部材１４の凹形状部分に嵌合する。グリップ側継手部材１５１及び外筒側継手部材１４は、図の左右方向に貫通する不図示の貫通孔を有し、この貫通孔を連結ボルト１４１が挿通する。そして、連結ボルト１４１が座金１４３にも挿通し、ナット１４２に螺合されることにより、グリップ１５は外筒１２に固定される。このようにグリップ１５を有することにより、作業者は測定器取付治具１を把持しやすくなるため、作業性を向上させることができる。
The outer cylinder 12 includes an outer cylinder side joint member 14. The outer cylinder 12 and the outer cylinder side joint member 14 can be integrally injection-molded. The grip 15 includes a grip side joint member 151. The grip side joint member 151 is fitted into the concave portion of the outer cylinder side joint member 14. The grip side joint member 151 and the outer cylinder side joint member 14 have a through hole (not shown) penetrating in the left-right direction in the figure, and the connecting bolt 141 is inserted through the through hole. The connecting bolt 141 is also inserted into the washer 143 and screwed into the nut 142, whereby the grip 15 is fixed to the outer cylinder 12. By having the grip 15 in this manner, the operator can easily grip the measuring instrument mounting jig 1, and thus the workability can be improved.
図３は、測定器取付治具１における遊び空間１１１ｂの第１説明図である。図４は、測定器取付治具１における遊び空間１１１ｂの第２説明図である。図５は、測定器取付治具１における遊び空間１１１ｂの第３説明図である。
FIG. 3 is a first explanatory view of the play space 111 b in the measuring instrument mounting jig 1. FIG. 4 is a second explanatory view of the play space 111 b in the measuring instrument mounting jig 1. FIG. 5 is a third explanatory view of the play space 111 b in the measuring instrument mounting jig 1.
図３から図５には、心棒１１と、外筒１２の一部と、連結ピン１２１と、ナット１２２と、心棒側継手部材１３が示されている。また、心棒１１においては、連結ピン摺動溝１１１ａと遊び空間１１１ｂが示されている。また、図３から図５は、いずれも心棒１１から外筒１２が引き抜かれた状態を示している。
3 to 5 show the mandrel 11, a part of the outer cylinder 12, the connecting pin 121, the nut 122, and the mandrel side joint member 13. FIG. Further, in the mandrel 11, a connecting pin sliding groove 111a and a play space 111b are shown. 3 to 5 show a state where the outer cylinder 12 is pulled out from the mandrel 11.
遊び空間１１１ｂは、図３から図５に示されるように、連結ピン１２１に対して十分に広い開口を有している。このため、図３に示されるように連結ピン１２１が遊び空間１１１ｂの中央部よりも若干下側を挿通している状態においては当然に連結ピン１２１が遊び空間１１１ｂの縁には接触しにくい。
The play space 111b has a sufficiently wide opening with respect to the connecting pin 121, as shown in FIGS. For this reason, as shown in FIG. 3, in a state where the connecting pin 121 is inserted slightly below the center of the play space 111b, the connecting pin 121 naturally does not come into contact with the edge of the play space 111b.
また、前述のように、心棒の挿入端１１ａの先端から遊び空間１１１ｂの縁までの距離が短く、かつ、前述のように突出部１２４により連結ピン１２１が外筒１２の被挿入端１２ａよりも突出した位置に設けられている。また、心棒１１に遊び空間１１１ｂがあるため外筒１２の力が伝わりにくい。そして、連結ピン１２１を軸として外筒１２を回転させるような変位を生じさせた場合であっても、心棒１１にその変位による外力を伝達しにくくすることができる。
Further, as described above, the distance from the tip of the insertion end 11a of the mandrel to the edge of the play space 111b is short, and as described above, the connecting pin 121 is more than the insertion end 12a of the outer cylinder 12 by the protruding portion 124. It is provided at the protruding position. Further, since the mandrel 11 has the play space 111b, the force of the outer cylinder 12 is not easily transmitted. And even if it is a case where the displacement which rotates the outer cylinder 12 centering on the connection pin 121 is produced, it can make it difficult to transmit the external force by the displacement to the mandrel 11.
また、図４及び図５に示されるように、外筒１２が心棒１１の軸回りに若干の回転角を有した状態でも、遊び空間１１１ｂ内で連結ピン１２１が移動できるので、連結ピン１２１が遊び空間１１１ｂの縁に接触することなく、外筒１２は心棒１１に対して比較的自由に軸回りに回転することができる。そして、外筒１２からの外力を心棒１１に伝達しにくくすることができる。
As shown in FIGS. 4 and 5, the connecting pin 121 can move in the play space 111b even when the outer cylinder 12 has a slight rotation angle around the axis of the mandrel 11. The outer cylinder 12 can rotate about the axis relatively freely with respect to the mandrel 11 without contacting the edge of the play space 111b. Then, it is possible to make it difficult to transmit the external force from the outer cylinder 12 to the mandrel 11.
図６は、遊び空間が設けられていない参考例の心棒の説明図である。図６には、参考例における心棒１０１１と外筒１０１２が示されている。また、外筒１０１２に掛け渡された連結ピン１１２１と、連結ピン１１２１を外筒１０１２に固定するナット１１２２が示されている。
FIG. 6 is an explanatory diagram of a mandrel of a reference example in which no play space is provided. FIG. 6 shows a mandrel 1011 and an outer cylinder 1012 in the reference example. Further, a connection pin 1121 spanned over the outer cylinder 1012 and a nut 1122 for fixing the connection pin 1121 to the outer cylinder 1012 are shown.
参考例の心棒１０１１は、本実施形態における遊び空間のような広い開口を有しておらず、貫通孔１１１の縁で必ず連結ピン１１２１が接触してしまう。すなわち、作業者が把持する外筒１０１２の位置がブレた場合に、連結ピン１１２１が心棒１０１１の内側に接触し、作業者からの外力が心棒１０１１に伝わってしまう。
The mandrel 1011 of the reference example does not have a wide opening like the play space in this embodiment, and the connecting pin 1121 always comes into contact with the edge of the through hole 111. That is, when the position of the outer cylinder 1012 held by the worker is shaken, the connecting pin 1121 comes into contact with the inner side of the mandrel 1011, and the external force from the worker is transmitted to the mandrel 1011.
これに対し、本実施形態における測定器取付治具１であれば、上述の通り、大きな遊び空間１１１ｂを有するので、心棒１１から外筒１２を引き抜いた状態において、連結ピン１２１は遊び空間１１１ｂの縁に接触しないようにすることができる。すなわち、作業者からの外力が心棒１１に伝わりにくくすることができる。
On the other hand, the measuring instrument mounting jig 1 according to the present embodiment has the large play space 111b as described above. Therefore, in the state where the outer cylinder 12 is pulled out from the mandrel 11, the connecting pin 121 is connected to the play space 111b. The edges can be prevented from touching. That is, it is possible to make it difficult for the external force from the operator to be transmitted to the mandrel 11.
図７は、測定器２００を測定器取付治具１に固定する様子の説明図である。なお、同図に示す状態では、心棒１１は外筒１２に挿入されている。本実施形態における測定器２００は、測定器取付治具１を用いて気中開閉器３００（図８を参照。取付相手に相当）に取り付けられる。気中開閉器３００は、電柱等に固定される開閉器であるが、外面の腐食等によりその内部に雨水の浸水が発生する場合がある。そのため、測定器２００は、気中開閉器３００内の浸水量を推定するためデータを取得することに用いられる。
FIG. 7 is an explanatory diagram showing a state in which the measuring device 200 is fixed to the measuring device mounting jig 1. In the state shown in the figure, the mandrel 11 is inserted into the outer cylinder 12. The measuring device 200 in this embodiment is attached to the air switch 300 (refer to FIG. 8, which corresponds to a mounting partner) using the measuring device mounting jig 1. The in-air switch 300 is a switch that is fixed to a utility pole or the like, but rainwater may be flooded inside due to corrosion of the outer surface or the like. Therefore, the measuring device 200 is used to acquire data in order to estimate the amount of water in the air switch 300.
前述のように、気中開閉器３００は主に電柱に取り付けられ、また仮に浸水している場合に底部に水が溜まることから、測定器２００は気中開閉器３００の底面に取り付けられることになる。そのため、本実施形態における測定器２００は、その上面側に温度を測定するための温度センサー２２０と、加熱するためのヒーター２３０を備える。また、測定器２００は、その上面側に気中開閉器３００に吸着するための真空ポンプ付吸盤２１０を備える。そして、ヒーター２３０により気中開閉器３００を加熱し、そのときの温度上昇を測定する。そして、その測定値に基づいて浸水量が推定される。
As described above, the aerial switch 300 is mainly attached to the utility pole, and water is collected at the bottom when it is submerged, so that the measuring instrument 200 is attached to the bottom surface of the aerial switch 300. Become. Therefore, the measuring instrument 200 in this embodiment includes a temperature sensor 220 for measuring temperature and a heater 230 for heating on the upper surface side. Moreover, the measuring device 200 is equipped with the suction cup 210 with a vacuum pump for adsorb | sucking to the air switch 300 in the upper surface side. And the air switch 300 is heated with the heater 230, and the temperature rise at that time is measured. And the amount of inundation is estimated based on the measured value.
測定器２００は、その底面側に本実施形態における測定器取付治具１に固定されるための測定器側継手部材２０１を備える。図７に示されるように、測定器側継手部材２０１の嵌合部２０１ａの形状は、心棒側継手部材１３の嵌合部１３ａの形状と一致している。このため、図７の図中奥側から図中手前側に向かって測定器側継手部材２０１を心棒側継手部材１３を摺動移動させることにより、測定器側継手部材２０１の嵌合部２０１ａが心棒側継手部材１３の嵌合部１３ａに嵌合した状態となり、図中左右方向における移動を拘束する。
The measuring instrument 200 includes a measuring instrument side joint member 201 for fixing to the measuring instrument mounting jig 1 in the present embodiment on the bottom surface side. As shown in FIG. 7, the shape of the fitting portion 201 a of the measuring instrument side joint member 201 matches the shape of the fitting portion 13 a of the mandrel side joint member 13. For this reason, the fitting part 201a of the measuring instrument side joint member 201 is moved by sliding the measuring instrument side joint member 201 from the back side in FIG. It will be in the state fitted to the fitting part 13a of the mandrel side coupling member 13, and restrains the movement in the left-right direction in the figure.
また、測定器側継手部材１０１及び心棒側継手部材１３には、図７の図中左右方向にそれぞれの中心軸が一致する貫通孔２０１ｂ、１３ｂが形成されている。そのため、連結ボルト１３１を貫通孔２０１ｂ、１３ｂ及び座金１３３に挿通し、ナット１３２と螺合することにより、確実に、測定器側継手部材１０１を心棒側継手部材１３に固定することができる。そして、測定器２００と心棒１１を確実に固定することができる。
Further, the measuring instrument side joint member 101 and the mandrel side joint member 13 are formed with through holes 201b and 13b whose center axes coincide with each other in the left-right direction in FIG. Therefore, the measuring instrument side joint member 101 can be reliably fixed to the mandrel side joint member 13 by inserting the connecting bolt 131 through the through holes 201b and 13b and the washer 133 and screwing with the nut 132. And the measuring device 200 and the mandrel 11 can be reliably fixed.
図８は、測定器２００を気中開閉器３００に接触させる様子の説明図である。上記のようにして測定器２００が測定器取付治具１に固定されると、作業者はグリップ１５を把持して上方に移動させることにより測定器２００を測定対象３００に接触させることができる。
FIG. 8 is an explanatory diagram showing a state in which the measuring device 200 is brought into contact with the air switch 300. When the measuring instrument 200 is fixed to the measuring instrument mounting jig 1 as described above, the operator can bring the measuring instrument 200 into contact with the measuring object 300 by holding the grip 15 and moving it upward.
このとき、心棒１１は自重及び測定器２００の重量により外筒１２内に挿入される。そして、心棒１１の半径方向の移動は外筒１２により拘束される。そのため、外筒１２を単に上方に移動させることで測定器２００を安全に上方に移動させることができる。そして、測定器２００の上面を確実に気中開閉器３００の下面に接触させることができる。
At this time, the mandrel 11 is inserted into the outer cylinder 12 due to its own weight and the weight of the measuring device 200. The radial movement of the mandrel 11 is restrained by the outer cylinder 12. Therefore, the measuring instrument 200 can be safely moved upward by simply moving the outer cylinder 12 upward. And the upper surface of the measuring device 200 can be made to contact the lower surface of the air switch 300 reliably.
測定器２００が気中開閉器３００に接触させられると、真空ポンプ付吸盤２１０において真空ポンプが作動される。すると真空ポンプ付吸盤２１０が気中開閉器３００の底面に吸着するため、測定器２００は気中開閉器３００の底面に固定される。また、このとき、温度センサー２２０とヒーター２３０も気中開閉器３００の底面に接触する。このようにすることにより、ヒーター２３０により気中開閉器３００の底面を加熱して、このときの温度変化を温度センサー２２０で測定することができる。
When the measuring device 200 is brought into contact with the air switch 300, the vacuum pump is operated in the suction cup 210 with the vacuum pump. Then, since the suction cup 210 with the vacuum pump is adsorbed on the bottom surface of the air switch 300, the measuring device 200 is fixed to the bottom surface of the air switch 300. At this time, the temperature sensor 220 and the heater 230 are also in contact with the bottom surface of the air switch 300. By doing in this way, the bottom face of the air switch 300 can be heated by the heater 230, and the temperature change at this time can be measured by the temperature sensor 220.
図９は、測定器２００の取付後の説明図である。上記のようにして、測定器２００が気中開閉器３００の底面に固定されると、外筒１２を下方に引き下ろして心棒１１が外筒１２から引き出された状態とすることができる。このように、測定器２００が気中開閉器に吸着してしまえば、測定器２００を支える必要がないため作業者の負担が軽減される。
FIG. 9 is an explanatory diagram after the measuring instrument 200 is attached. As described above, when the measuring instrument 200 is fixed to the bottom surface of the air switch 300, the outer cylinder 12 can be pulled downward so that the mandrel 11 is pulled out from the outer cylinder 12. In this way, if the measuring device 200 is adsorbed to the air switch, it is not necessary to support the measuring device 200, so the burden on the operator is reduced.
また、外筒１２を引き下げて心棒１１が外筒１２から引き出された状態とすることで、心棒１１に対する外筒１２の拘束を解除することができる。前述のように、心棒１１の遊び空間１１１ｂは、連結ピン１２１よりも広い開口を有することから、遊び空間１１１ｂの縁に連結ピン１２１が接触しにくいため、外筒１２の変位を心棒１１に伝達しにくくすることができる。そのため、作業者が外筒１２を多少動かした場合であっても、測定装置２００には外筒の変位に伴う力はほとんど作用しない。
Further, by pulling down the outer cylinder 12 to bring the mandrel 11 into a state of being pulled out from the outer cylinder 12, the restraint of the outer cylinder 12 with respect to the mandrel 11 can be released. As described above, since the play space 111b of the mandrel 11 has an opening wider than the connecting pin 121, the connecting pin 121 is unlikely to contact the edge of the play space 111b, so that the displacement of the outer cylinder 12 is transmitted to the mandrel 11. Can be difficult. Therefore, even when the operator moves the outer cylinder 12 to some extent, the force accompanying the displacement of the outer cylinder hardly acts on the measuring apparatus 200.
図１０は、測定器２００の取付後における外筒１２の自由度の説明図である。前述の図９のように外筒１２を引き抜いた後において、図１０に示すように外筒１２を心棒１１に対して傾けるようにその位置を変更することができる。
FIG. 10 is an explanatory diagram of the degree of freedom of the outer cylinder 12 after the measuring instrument 200 is attached. After the outer cylinder 12 is pulled out as shown in FIG. 9, the position of the outer cylinder 12 can be changed so as to be inclined with respect to the mandrel 11 as shown in FIG.
このような動きが可能なのは、前述のように、心棒の挿入端１１ａの先端から遊び空間１１１ｂの縁までの距離が短く、かつ、前述のように突出部１２４により連結ピン１２１が外筒１２の被挿入端１２ａよりも突出した位置に設けられているためである。このように構成することにより、心棒１１から外筒１２が引き抜かれた状態において、心棒１１の挿入端１１ａを外筒１２の被挿入端１２ａに接触しにくくすることができる。
As described above, such movement is possible because the distance from the tip of the insertion end 11a of the mandrel to the edge of the play space 111b is short, and the connecting pin 121 of the outer cylinder 12 is caused by the protrusion 124 as described above. This is because it is provided at a position protruding from the insertion end 12a. By configuring in this way, it is possible to make it difficult for the insertion end 11 a of the mandrel 11 to come into contact with the inserted end 12 a of the outer cylinder 12 in a state where the outer cylinder 12 is pulled out from the mandrel 11.
このように、外筒１２を心棒１１に対して傾けることが可能であるので、グリップ１５を介して外筒１２を把持する作業者は、測定器２００の取付後において比較的自由に外筒１２の位置を移動させることができる。そのため、作業者は同じ位置でグリップ１５を把持し続けなくてもよいため、その負担を軽減することができる。
Thus, since the outer cylinder 12 can be tilted with respect to the mandrel 11, an operator who holds the outer cylinder 12 via the grip 15 can freely move the outer cylinder 12 after the measuring instrument 200 is attached. Can be moved. Therefore, the operator does not have to keep gripping the grip 15 at the same position, so that the burden can be reduced.
また、心棒１１の挿入端１１ａの先端部が半球形状を有するので、心棒１１が外筒１２に対して連結ピン１２１を軸として回転する場合において、心棒１１の挿入端１１ａが外筒１２の被挿入端１２ａに引っかかりにくい。そのため、連結ピン１２１を軸として作業者が外筒１２を回転させるような変位を生じさせた場合であっても、心棒１１にその変位による外力を伝達しにくくすることができる。
Further, since the distal end portion of the insertion end 11 a of the mandrel 11 has a hemispherical shape, when the mandrel 11 rotates about the connecting pin 121 with respect to the outer cylinder 12, the insertion end 11 a of the mandrel 11 is covered by the outer cylinder 12. It is difficult to catch on the insertion end 12a. Therefore, even if the worker causes a displacement that rotates the outer cylinder 12 around the connecting pin 121 as an axis, it is difficult to transmit the external force due to the displacement to the mandrel 11.
以上のように測定器２００を気中開閉器３００に取り付けた後、測定が終了すると、測定器２００の取り外しを行う。取り外しを行うに際には、外筒１２に心棒１１を挿入するように外筒１２を持ち上げる。そして、心棒１１の半径方向の動きを拘束する。
After the measurement device 200 is attached to the air switch 300 as described above, the measurement device 200 is removed when the measurement is completed. When removing, the outer cylinder 12 is lifted so that the mandrel 11 is inserted into the outer cylinder 12. Then, the movement of the mandrel 11 in the radial direction is restrained.
このとき、心棒１１は連結ピン摺動溝１１１ａを備えるので、連結ピン摺動溝１１１ａに連結ピン１２１が通り、その移動経路を案内することにより、心棒１１をより容易に外筒１２に挿入することができる。さらに、心棒１１は傾斜部１１３を備えるので、連結ピン１２１が遊び空間１１１ｂから連結ピン摺動溝１１１ａに移動する際に傾斜部１１３を摺動することができる。これにより、連結ピン摺動溝１１１ａに連結ピン１２１を案内しやすくなるため、心棒１１をより容易に外筒１２に挿入することができる。
At this time, since the mandrel 11 is provided with the connecting pin sliding groove 111a, the connecting pin 121 passes through the connecting pin sliding groove 111a, and the mandrel 11 is more easily inserted into the outer cylinder 12 by guiding its moving path. be able to. Furthermore, since the mandrel 11 includes the inclined portion 113, the inclined portion 113 can be slid when the connecting pin 121 moves from the play space 111b to the connecting pin sliding groove 111a. Thereby, since it becomes easy to guide the connecting pin 121 to the connecting pin sliding groove 111a, the mandrel 11 can be inserted into the outer cylinder 12 more easily.
また、遊び空間１１１ｂは連結ピン１２１よりも広い開口を有しているので、心棒１１の挿入を行う際において、心棒１１と外筒１２は互いに中心軸回りに若干の回転を許容することができる。そして、心棒１１の挿入をより容易にし、作業性を向上させることができる。
Further, since the play space 111b has an opening wider than the connecting pin 121, when the mandrel 11 is inserted, the mandrel 11 and the outer cylinder 12 can allow a slight rotation around the central axis. . Then, the mandrel 11 can be more easily inserted and workability can be improved.
図１１は、測定器２００が気中開閉器３００から外れてしまったときの説明図である。前述の図１０の状態において、吸盤２１０の劣化等を原因として吸着力が低下し、測定器２００が気中開閉器３００の底面から外れてしまう場合が考えられる。このような場合であっても、連結ピン１２１が貫通孔１１１に挿通されているので、心棒１１は外筒１２に連結されたままである。よって、作業者がグリップ１５を把持している限り、心棒１１に固定された測定器２００が落下するのを防止することができる。
FIG. 11 is an explanatory diagram when the measuring device 200 is detached from the air switch 300. In the state of FIG. 10 described above, the suction force may be reduced due to deterioration of the suction cup 210 and the like, and the measuring device 200 may be detached from the bottom surface of the air switch 300. Even in such a case, since the connecting pin 121 is inserted into the through hole 111, the mandrel 11 remains connected to the outer cylinder 12. Therefore, as long as the operator holds the grip 15, the measuring device 200 fixed to the mandrel 11 can be prevented from falling.
以上のように、本実施形態における測定器取付治具１によれば、測定器２００のような取付対象物を気中開閉器３００のような取付相手に取り付ける際には、心棒１１が外筒１２に挿入されることで、外筒１２に対して心棒１１の半径方向の移動が拘束される。これにより、外筒１２を把持する作業者により確実に取付対象物を取付相手に接触させることができる。
As described above, according to the measuring instrument mounting jig 1 in the present embodiment, when mounting an object to be mounted such as the measuring instrument 200 to a mounting partner such as the air switch 300, the mandrel 11 is the outer cylinder. As a result, the movement of the mandrel 11 in the radial direction is restrained with respect to the outer cylinder 12. As a result, the worker holding the outer cylinder 12 can reliably bring the attachment object into contact with the attachment counterpart.
また、取付対象物を取付相手に取り付けた後においては、外筒１２を下方に引き下ろして心棒１１が外筒１２から引き出された状態とすることで、心棒１１に対する外筒１２の拘束を解除することができる。このとき、遊び空間１１１ｂは、連結ピン１２１の直径よりも広い開口を有することから、遊び空間１１１ｂの縁に連結ピン１２１が接触しにくい。そのため、外筒１２の変位を心棒１１に伝達しにくくすることができる。
In addition, after the attachment object is attached to the attachment counterpart, the outer cylinder 12 is pulled downward to bring the mandrel 11 into the state of being pulled out of the outer cylinder 12, thereby releasing the restraint of the outer cylinder 12 with respect to the mandrel 11. be able to. At this time, since the play space 111b has an opening wider than the diameter of the connection pin 121, the connection pin 121 is unlikely to contact the edge of the play space 111b. Therefore, it is possible to make it difficult to transmit the displacement of the outer cylinder 12 to the mandrel 11.
また、このような状況下で、仮に、取付対象物が取付相手から外れた場合であっても、連結ピン１２１が遊び空間１１１ｂに挿通していることから、心棒１１は外筒１２に連結されたままである。よって、心棒１１に固定された取付対象物が落下するのを防止することができる。
Also, under such circumstances, the mandrel 11 is connected to the outer cylinder 12 because the connecting pin 121 is inserted into the play space 111b even if the attachment object is detached from the attachment counterpart. It remains. Therefore, it is possible to prevent the attachment object fixed to the mandrel 11 from falling.
図１２は、自在継手２０を用いて測定器２００を上方の気中開閉器３００に接触させるときの説明図である。前述の実施形態では、測定器２００と心棒１１は、心棒側継手部材１３と測定器側継手部材２０１によってその位置を固定されていた。この場合、測定器２００の取付方向に向かうように作業者がグリップ１５を把持しなければならず、例えば、狭い場所などの作業性の悪い環境においては、測定器２００の取り付けを行いにくい場合もある。
FIG. 12 is an explanatory diagram when the measuring device 200 is brought into contact with the upper air switch 300 using the universal joint 20. In the above-described embodiment, the positions of the measuring instrument 200 and the mandrel 11 are fixed by the mandrel-side joint member 13 and the measuring instrument-side joint member 201. In this case, the operator must hold the grip 15 so as to face the mounting direction of the measuring instrument 200. For example, it may be difficult to mount the measuring instrument 200 in a poor workability environment such as a narrow place. is there.
これに対し、図１２に示すように、心棒１１の非挿入端１１ｂ側に自在継手２０を取り付け、この自在継手２０を介して測定器２００と連結することもできる。自在継手２０は、測定器２００と心棒１１の接合する角度を自由に変化させることができる。このため、例えば図１２に示すように、心棒１１の軸方向と測定器２００の取付方向が一致しない場合であっても、測定器２００を気中開閉器３００に取り付けることができる。そして、作業者の作業性を高めることができる。
On the other hand, as shown in FIG. 12, a universal joint 20 can be attached to the non-insertion end 11 b side of the mandrel 11 and can be connected to the measuring instrument 200 via the universal joint 20. The universal joint 20 can freely change the angle at which the measuring instrument 200 and the mandrel 11 are joined. For this reason, for example, as shown in FIG. 12, even when the axial direction of the mandrel 11 and the mounting direction of the measuring device 200 do not coincide with each other, the measuring device 200 can be mounted on the air switch 300. And the workability | operativity of an operator can be improved.
