Description

本発明は、高所用作業者のバケット内等での間接活線作業で使用される共用操作棒の固定台及びこれを用いた共用操作棒に関する。   TECHNICAL FIELD The present invention relates to a common operating rod fixing base used in indirect hot-line work in a bucket of an aerial worker and a common operating rod using the same.

たとえば、高所作業車のバケット内で間接活線作業を行う場合、複数の共用操作棒を用いて作業内容に応じた先端工具に先端部を付け替えて作業をし、作業工程の一部が終了すると次の作業工程で必要になるまでバケット内に共用操作棒を立て掛けている。   For example, when performing indirect hot-line work in a bucket of an aerial work vehicle, use a plurality of common operation rods to change the tip to the tip tool according to the work content, and part of the work process is completed Then, the common operation stick is stood in the bucket until it becomes necessary in the next work process.

ところが、バケット内に共用操作棒を斜めに立て掛けると、作業の邪魔になったり、共用操作棒同士が絡まったりするため作業性が悪化する問題がある。
また、作業者が立て掛けた共用操作棒を手にしたときに、絡まった共用操作棒が不意に飛び出して怪我するおそれや、バケット内を整理する手間と時間がかかり、作業時間が延びる問題もある。 However, when the common operation rod is stood diagonally in the bucket, there is a problem that workability is deteriorated because it interferes with the work or the common operation rods are entangled with each other.
In addition, when the operator holds the common operation rod leaning up, there is a risk that the tangled common operation rod may unexpectedly jump out and get injured. .

そこで、複数の共用操作棒を収容可能な収納袋をバケットの外側にフックで取り付けて、使用していない共用操作棒をこの収納袋に入れて管理することが考えられている（特許文献１参照）。   Therefore, it is considered that a storage bag that can accommodate a plurality of common operation rods is attached to the outside of the bucket with a hook, and an unused common operation rod is placed in the storage bag for management (see Patent Document 1). ).

また、２本の共用操作棒を同時に使用して作業する場合には、バケットの淵を挟み込むようにして固定台を設置し、この固定台に一方の共用操作棒を固定する固定器具を使用して作業を行うことも提案されている（特許文献２参照）。   Also, when working with two shared operation bars at the same time, install a fixing base with the bucket hooks in between, and use a fixing device that fixes one of the common operation bars to the fixed base. It is also proposed to perform the work (see Patent Document 2).

しかしながら、特許文献１に記載の収納袋では、共用操作棒を収納袋から引き上げるときに、絡まった他の共用操作棒も同時に引き上げられるおそれがあるため、不意に共用操作棒を落下させないように慎重に共用操作棒を出し入れしたり、共用操作棒同士が絡まるのを防止するため、収納袋に収納する都度整理をしなくてはならないため手間がかかり作業性が悪い問題がある。
また、共用操作棒に先端工具を取り付けて収納袋に収納するため、重い先端工具が共用操作棒に装着されている場合、収納袋が反転して落下するおそれがある。 However, in the storage bag described in Patent Document 1, when the common operation rod is pulled up from the storage bag, other common operation rods that are entangled may be lifted at the same time, so be careful not to accidentally drop the common operation rod. In order to prevent the common operation rods from being taken in and out and the common operation rods from being entangled with each other, it must be arranged every time it is stored in the storage bag.
Further, since the tip tool is attached to the common operation rod and stored in the storage bag, when the heavy tip tool is mounted on the common operation rod, the storage bag may be inverted and dropped.

さらに、特許文献２に記載の固定器具は、複数の操作棒を固定するためには、固定器具もその数に応じて必要になり、重い固定器具をバケットに取り付けなければならず、作業時間が長くなり作業性が悪い問題がある。   Furthermore, in order to fix a plurality of operation rods, the fixing device described in Patent Document 2 requires fixing devices according to the number thereof, and a heavy fixing device must be attached to the bucket. There is a problem that it becomes long and the workability is bad.

本発明は、かかる事情に鑑みてなされたものであり、間接活線作業の作業性を損なわずに作業箇所（たとえば、高所作業車のバケット内）を容易に整理することができる共用操作棒の固定台及びこれを用いた共用操作棒を提供することを主たる課題としている。   The present invention has been made in view of such circumstances, and a common operation bar that can easily organize work locations (for example, in the bucket of an aerial work vehicle) without impairing the workability of indirect hot-line work. The main object is to provide a fixed base and a shared operation rod using the same.

上記課題を達成するために、本発明に係る共用操作棒の固定台は、共用操作棒のジョイント部に接続可能に形成された接続部と、前記接続部の軸線上に設けられ床面に対して自立可能に形成された土台部とを有して構成され、前記土台部の底面の幅は、前記共用操作棒のツバの幅よりも大きく形成されることを特徴としている。   To achieve the above object, a common operating rod fixing base according to the present invention includes a connecting portion formed to be connectable to a joint portion of the common operating rod, and a floor provided on an axis of the connecting portion. And a base portion formed so as to be able to stand by itself, wherein the width of the bottom surface of the base portion is larger than the width of the flange of the common operation rod.

共用操作棒の固定台の土台部の底面の幅が、共用操作棒のツバの幅よりも大きく形成されることで、共用操作棒に接続して床面に立設したときに共用操作棒が転倒することを防ぐことができ、作業性を損なわずに作業箇所を容易に整理することが可能となる。
特に、共用操作棒を横倒しに置いたときに、共用操作棒に設けられたゴム製のツバは、荷重を受けることにより変形し、その状態が長期間継続するとツバが劣化して塑性変形することになるが、土台部の底面の幅がツバの幅より大きいことで、ツバに共用操作棒の荷重がかかることを防ぎ、ツバの塑性変形を防止することが可能となる。
また、高所作業車のバケットの床面に立設させた場合には、収納袋を利用せずにバケット内を整理することが可能となるため、袋が反転して共用操作棒が落下する落下事故を防ぐことができる。 The width of the bottom of the base of the fixed base of the common operation rod is formed to be larger than the width of the common operation rod head, so that the common operation rod can be connected to the common operation rod when standing on the floor. It is possible to prevent the vehicle from toppling over, and it is possible to easily arrange the work points without impairing workability.
In particular, when the common operation rod is placed on its side, the rubber collar provided on the common operation rod is deformed by receiving a load, and if the state continues for a long time, the collar deteriorates and plastically deforms. However, if the width of the bottom surface of the base portion is larger than the width of the brim, it is possible to prevent the load of the common operation rod from being applied to the brim and to prevent plastic deformation of the brim.
Also, when standing on the floor of a bucket of an aerial work vehicle, it is possible to organize the bucket without using a storage bag, so the bag is inverted and the common operation rod falls A fall accident can be prevented.

土台部の重量は、共用操作棒よりも重くしてもよい。
土台部の重量は、共用操作棒よりも重いことにより、固定台がより安定して共用操作棒を支えることができ、共用操作棒の転倒を防ぐことが可能となる。 The weight of the base portion may be heavier than the common operation rod.
Since the weight of the base portion is heavier than the common operation rod, the fixed base can more stably support the common operation rod and prevent the common operation rod from falling.

また、土台部は、円錐台状に形成されるようにしてもよい。
土台部が円錐台に形成されることで、共用操作棒の重心をより床面方向にすることが可能となり、また、床面との接触面積を大きく確保することが可能となり安定して共用操作棒を立てることが可能となる。
また、共用操作棒を横倒しにして置いたときに、基端部に重心が偏ることを防止することが可能になるため、土台部の重みにより共用操作棒が不意に立ち上がることを防止することが可能となる。 Further, the base portion may be formed in a truncated cone shape.
By forming the base in a truncated cone, it is possible to make the center of gravity of the common operation rod more toward the floor surface, and it is possible to secure a large contact area with the floor surface, and stable common operation It is possible to stand a stick.
In addition, when the common operation rod is placed on its side, it is possible to prevent the center of gravity from being biased to the base end, so that the common operation rod can be prevented from unexpectedly rising due to the weight of the base portion. It becomes possible.

共用操作棒の軸方向を床面と略平行にして前記共用操作棒を載置するとき、前記共用操作棒の先端部近傍と前記土台部の底面の淵とのみが前記床面に接触するように前記土台部の底面の大きさが設定されていることを特徴とするように形成されてもよい。   When the common operation rod is placed with the common operation rod axially substantially parallel to the floor surface, only the vicinity of the tip of the common operation rod and the bottom surface of the base portion are in contact with the floor surface. The base may be formed so that the size of the bottom surface is set.

共用操作棒の先端部の近傍と土台部の底面の淵とのみが床面に接触するように前記土台部の底面の大きさが設定されることで、ツバに共用操作棒の荷重がかかることを確実に防ぎ、ツバの塑性変形を防止することが可能となる。   The size of the bottom surface of the base portion is set so that only the vicinity of the tip of the common operation rod and the ridges on the bottom surface of the base portion are in contact with the floor surface, so that the load of the common operation rod is applied to the brim Can be reliably prevented, and the plastic deformation of the brim can be prevented.

このように構成された共用操作棒の固定台がジョイント部に接続された共用操作棒として使用されてもよい。   The fixed base of the common operation rod configured as described above may be used as a common operation rod connected to the joint portion.

以上述べたように、本発明の共用操作棒の固定台によれば、共用操作棒の固定台の土台部の底面の幅が、共用操作棒のツバの幅よりも大きく形成されることで、共用操作棒に接続して床面に立設したときに共用操作棒が転倒することを防ぐことができ、作業性を損なわずに作業箇所を容易に整理することが可能となることで作業時間の短縮を図ることができる。
特に、共用操作棒を横倒しに置いたときに、共用操作棒に設けられたゴム製のツバは、荷重を受けることにより変形し、その状態が長期間継続するとツバが劣化して塑性変形することになるが、土台部の底面の幅がツバの幅より大きいことで、ツバに共用操作棒の荷重がかかることを防ぎ、ツバの塑性変形を防止することが可能となる。
また、高所作業車のバケットの床面に立設させた場合には、収納袋を利用せずにバケット内を整理することが可能となるため、袋が反転して共用操作棒が落下する落下事故を防ぐことができる。 As described above, according to the common operation rod fixing base of the present invention, the width of the bottom surface of the base portion of the common operation rod fixing base is formed larger than the width of the common operation rod flange, Work time by connecting the common operation rod and standing on the floor can prevent the common operation rod from falling over and easily organize the work place without impairing workability Can be shortened.
In particular, when the common operation rod is placed on its side, the rubber collar provided on the common operation rod is deformed by receiving a load, and if the state continues for a long time, the collar deteriorates and plastically deforms. However, if the width of the bottom surface of the base portion is larger than the width of the brim, it is possible to prevent the load of the common operation rod from being applied to the brim and to prevent plastic deformation of the brim.
Also, when standing on the floor of a bucket of an aerial work vehicle, it is possible to organize the bucket without using a storage bag, so the bag is inverted and the common operation rod falls A fall accident can be prevented.

The work time can be shortened by making it possible to organize the work.
In particular, when the common operation rod 2 is placed on its side, the width L of the bottom surface 18 of the base portion 12 is larger than the width M of both the flanges 25 and 26, so that the load of the common operation rod is applied to the flanges 25 and 26. , And the plastic deformation of the flanges 25 and 26 can be prevented.
In addition, since the common operation rod 2 is erected on the floor 31 of the bucket 3 of the aerial work vehicle, the inside of the bucket 3 can be arranged without using the storage bag. A fall accident in which the common operation rod 2 falls can be prevented.

また、土台部１２の重量は、共用操作棒２よりも重いことにより、共用操作棒の固定台１がより安定して共用操作棒２を支えることができ、共用操作棒２の転倒を防ぐことが可能となる。   Further, since the weight of the base portion 12 is heavier than the common operation rod 2, the common operation rod fixing base 1 can more stably support the common operation rod 2 and prevent the common operation rod 2 from falling over. Is possible.

さらに、土台部１２が円錐台に形成されることで、共用操作棒２の重心をよりバケット３の床面３１方向にすることが可能となり、また、バケット３の床面３１との接触面積を大きく確保することが可能となり安定して共用操作棒２を立てることが可能となる。
また、共用操作棒を横倒しにして置いたときに、基端部に重心が偏ることを防止することが可能になるため、土台部の重みにより共用操作棒が不意に立ち上がることを防止することが可能となる。 Furthermore, since the base portion 12 is formed in a truncated cone, the center of gravity of the common operation rod 2 can be made more toward the floor surface 31 of the bucket 3, and the contact area with the floor surface 31 of the bucket 3 can be increased. It is possible to secure a large size, and it is possible to stand the common operation rod 2 stably.
In addition, when the common operation rod is placed on its side, it is possible to prevent the center of gravity from being biased to the base end, so that the common operation rod can be prevented from unexpectedly rising due to the weight of the base portion. It becomes possible.

さらに、共用操作棒２の軸方向をバケット３の床面３１と略平行にして共用操作棒２を載置するとき、共用操作棒２の先端部２０の近傍（固定ネジ２０ａ）と土台部１２の底面の淵１８ａとのみがバケット３の床面３１に接触するように土台部１２の底面１８の大きさが設定されることで、雨切りツバ２５と限界ツバ２６とに共用操作棒２の荷重がかかること確実に防ぎ、両ツバ２５，２６の塑性変形を防止すること可能となる。   Further, when the common operation rod 2 is placed with the axial direction of the common operation rod 2 substantially parallel to the floor 31 of the bucket 3, the vicinity of the distal end portion 20 of the common operation rod 2 (fixing screw 20 a) and the base portion 12. The size of the bottom surface 18 of the base portion 12 is set so that only the ridge 18a on the bottom surface contacts the floor surface 31 of the bucket 3, so that the common operation rod 2 can be attached to the rain-cut flange 25 and the limit flange 26. It is possible to reliably prevent a load from being applied, and to prevent plastic deformation of both the flanges 25 and 26.

本発明は、高所用作業者のバケット内等での間接活線作業で使用される共用操作棒の共用操作棒の固定台及びこれを用いた共用操作棒に関する。   The present invention relates to a common operation rod fixing base for a common operation rod used in indirect hot-line work in a bucket of an aerial worker and a common operation rod using the same.

たとえば、高所作業車のバケット内で間接活線作業を行う場合、複数の共用操作棒を用いて作業内容に応じた先端工具に先端部を付け替えて作業をし、作業工程の一部が終了すると次の作業工程で必要になるまでバケット内に共用操作棒を立て掛けている。   For example, when performing indirect hot-line work in a bucket of an aerial work vehicle, use a plurality of common operation rods to change the tip to the tip tool according to the work content, and part of the work process is completed Then, the common operation stick is stood in the bucket until it becomes necessary in the next work process.

ところが、バケット内に共用操作棒を斜めに立て掛けると、作業の邪魔になったり、共用操作棒同士が絡まったりするため作業性が悪化する問題がある。
また、作業者が立て掛けた共用操作棒を手にしたときに、絡まった共用操作棒が不意に飛び出して怪我するおそれや、バケット内を整理する手間と時間がかかり、作業時間が延びる問題もある。 However, when the common operation rod is stood diagonally in the bucket, there is a problem that workability is deteriorated because it interferes with the work or the common operation rods are entangled with each other.
In addition, when the operator holds the common operation rod leaning up, there is a risk that the tangled common operation rod may unexpectedly jump out and get injured. .

そこで、複数の共用操作棒を収容可能な収納袋をバケットの外側にフックで取り付けて、使用していない共用操作棒をこの収納袋に入れて管理することが考えられている（特許文献１参照）。   Therefore, it is considered that a storage bag that can accommodate a plurality of common operation rods is attached to the outside of the bucket with a hook, and an unused common operation rod is placed in the storage bag for management (see Patent Document 1). ).

また、２本の共用操作棒を同時に使用して作業する場合には、バケットの淵を挟み込むようにして固定台を設置し、この固定台に一方の共用操作棒を固定する固定器具を使用して作業を行うことも提案されている（特許文献２参照）。   Also, when working with two shared operation bars at the same time, install a fixing base with the bucket hooks in between, and use a fixing device that fixes one of the common operation bars to the fixed base. It is also proposed to perform the work (see Patent Document 2).

しかしながら、特許文献１に記載の収納袋では、共用操作棒を収納袋から引き上げるときに、絡まった他の共用操作棒も同時に引き上げられるおそれがあるため、不意に共用操作棒を落下させないように慎重に共用操作棒を出し入れしたり、共用操作棒同士が絡まるのを防止するため、収納袋に収納する都度整理をしなくてはならないため手間がかかり作業性が悪い問題がある。
また、共用操作棒に先端工具を取り付けて収納袋に収納するため、重い先端工具が共用操作棒に装着されている場合、収納袋が反転して落下するおそれがある。 However, in the storage bag described in Patent Document 1, when the common operation rod is pulled up from the storage bag, other common operation rods that are entangled may be lifted at the same time, so be careful not to accidentally drop the common operation rod. In order to prevent the common operation rods from being taken in and out and the common operation rods from being entangled with each other, it must be arranged every time it is stored in the storage bag.
Further, since the tip tool is attached to the common operation rod and stored in the storage bag, when the heavy tip tool is mounted on the common operation rod, the storage bag may be inverted and dropped.

さらに、特許文献２に記載の固定器具は、複数の操作棒を固定するためには、固定器具もその数に応じて必要になり、重い固定器具をバケットに取り付けなければならず、作業時間が長くなり作業性が悪い問題がある。   Furthermore, in order to fix a plurality of operation rods, the fixing device described in Patent Document 2 requires fixing devices according to the number thereof, and a heavy fixing device must be attached to the bucket. There is a problem that it becomes long and the workability is bad.

本発明は、かかる事情に鑑みてなされたものであり、間接活線作業の作業性を損なわずに作業箇所（たとえば、高所作業車のバケット内）を容易に整理することができる共用操作棒の固定台及びこれを用いた共用操作棒を提供することを主たる課題としている。   The present invention has been made in view of such circumstances, and a common operation bar that can easily organize work locations (for example, in the bucket of an aerial work vehicle) without impairing the workability of indirect hot-line work. The main object is to provide a fixed base and a shared operation rod using the same.

上記課題を達成するために、本発明に係る共用操作棒の固定台は、共用操作棒のジョイント部に接続可能に形成された接続部と、前記接続部の軸線上に設けられ床面に対して自立可能に形成された土台部とを有して構成され、前記土台部は、内部が充填された円錐台状に形成され、また、前記土台部の底面の幅は、前記共用操作棒のツバの幅よりも大きく形成され、前記土台部の重量は、前記共用操作棒よりも重くなっており、前記共用操作棒の軸方向を前記床面と略平行にして前記共用操作棒を前記床面に載置するときに、前記共用操作棒の先端部近傍と前記土台部の底面の淵とのみが前記床面に接触するように前記土台部の底面の大きさが設定されていることを特徴としている。 To achieve the above object, a common operating rod fixing base according to the present invention includes a connecting portion formed to be connectable to a joint portion of the common operating rod, and a floor provided on an axis of the connecting portion. And the base portion is formed in a truncated cone shape filled with the inside, and the width of the bottom surface of the base portion is the same as that of the common operation rod. It is formed larger than the width of the brim, and the weight of the base portion is heavier than the common operation rod, and the common operation rod is placed in the floor with the axial direction of the common operation rod being substantially parallel to the floor surface. When mounting on a surface, the size of the bottom surface of the base portion is set so that only the vicinity of the tip of the common operation rod and the ridges on the bottom surface of the base portion are in contact with the floor surface. It is a feature.

共用操作棒の固定台の土台部の底面の幅が、共用操作棒のツバの幅よりも大きく形成されることで、共用操作棒に接続して床面に立設したときに共用操作棒が転倒することを防ぐことができ、作業性を損なわずに作業箇所を容易に整理することが可能となる。
特に、共用操作棒を横倒しに置いたときに、共用操作棒に設けられたゴム製のツバは、荷重を受けることにより変形し、その状態が長期間継続するとツバが劣化して塑性変形することになるが、土台部の底面の幅がツバの幅より大きいことで、ツバに共用操作棒の荷重がかかることを防ぎ、ツバの塑性変形を防止することが可能となる。
また、高所作業車のバケットの床面に立設させた場合には、収納袋を利用せずにバケット内を整理することが可能となるため、袋が反転して共用操作棒が落下する落下事故を防ぐことができる。
また、土台部の重量は、共用操作棒よりも重いことにより、固定台がより安定して共用操作棒を支えることができ、共用操作棒の転倒を防ぐことが可能となる。
さらに、土台部が円錐台に形成されることで、共用操作棒の重心をより床面方向にすることが可能となり、また、床面との接触面積を大きく確保することが可能となり安定して共用操作棒を立てることが可能となる。
さらにまた、共用操作棒を横倒しにして置いたときに、基端部に重心が偏ることを防止することが可能になるため、土台部の重みにより共用操作棒が不意に立ち上がることを防止することが可能となる。
また、共用操作棒の先端部の近傍と土台部の底面の淵とのみが床面に接触するように前記土台部の底面の大きさが設定されることで、ツバに共用操作棒の荷重がかかることを確実に防ぎ、ツバの塑性変形を防止することが可能となる。 The width of the bottom of the base of the fixed base of the common operation rod is formed to be larger than the width of the common operation rod head, so that the common operation rod can be connected to the common operation rod when standing on the floor. It is possible to prevent the vehicle from toppling over, and it is possible to easily arrange the work points without impairing workability.
In particular, when the common operation rod is placed on its side, the rubber collar provided on the common operation rod is deformed by receiving a load, and if the state continues for a long time, the collar deteriorates and plastically deforms. However, if the width of the bottom surface of the base portion is larger than the width of the brim, it is possible to prevent the load of the common operation rod from being applied to the brim and to prevent plastic deformation of the brim.
Also, when standing on the floor of a bucket of an aerial work vehicle, it is possible to organize the bucket without using a storage bag, so the bag is inverted and the common operation rod falls A fall accident can be prevented.
In addition, since the weight of the base portion is heavier than the common operation rod, the fixed base can support the common operation rod more stably, and the common operation rod can be prevented from falling.
Furthermore, since the base part is formed in the truncated cone, the center of gravity of the common operation rod can be made more toward the floor surface, and a large contact area with the floor surface can be ensured stably. It is possible to set up a common operation stick.
Furthermore , it is possible to prevent the center of gravity from being biased to the base end when the common operation rod is placed on its side, so that the common operation rod can be prevented from unexpectedly rising due to the weight of the base portion. Is possible.
In addition, since the size of the bottom surface of the base portion is set so that only the vicinity of the tip portion of the common operation rod and the ridges on the bottom surface of the base portion are in contact with the floor surface, the load of the common operation rod is applied to the brim. This can be reliably prevented, and the plastic deformation of the brim can be prevented.

このように構成された共用操作棒の固定台がジョイント部に接続された共用操作棒として使用されてもよい。   The fixed base of the common operation rod configured as described above may be used as a common operation rod connected to the joint portion.

以上述べたように、本発明の共用操作棒の固定台によれば、共用操作棒の固定台の土台部の底面の幅が、共用操作棒のツバの幅よりも大きく形成されることで、共用操作棒に接続して床面に立設したときに共用操作棒が転倒することを防ぐことができ、作業性を損なわずに作業箇所を容易に整理することが可能となることで作業時間の短縮を図ることができる。
特に、共用操作棒を横倒しに置いたときに、共用操作棒に設けられたゴム製のツバは、荷重を受けることにより変形し、その状態が長期間継続するとツバが劣化して塑性変形することになるが、土台部の底面の幅がツバの幅より大きいことで、ツバに共用操作棒の荷重がかかることを防ぎ、ツバの塑性変形を防止することが可能となる。
また、高所作業車のバケットの床面に立設させた場合には、収納袋を利用せずにバケット内を整理することが可能となるため、袋が反転して共用操作棒が落下する落下事故を防ぐことができる。 As described above, according to the common operation rod fixing base of the present invention, the width of the bottom surface of the base portion of the common operation rod fixing base is formed larger than the width of the common operation rod flange, Work time by connecting the common operation rod and standing on the floor can prevent the common operation rod from falling over and easily organize the work place without impairing workability Can be shortened.
In particular, when the common operation rod is placed on its side, the rubber collar provided on the common operation rod is deformed by receiving a load, and if the state continues for a long time, the collar deteriorates and plastically deforms. However, if the width of the bottom surface of the base portion is larger than the width of the brim, it is possible to prevent the load of the common operation rod from being applied to the brim and to prevent plastic deformation of the brim.
Also, when standing on the floor of a bucket of an aerial work vehicle, it is possible to organize the bucket without using a storage bag, so the bag is inverted and the common operation rod falls A fall accident can be prevented.
