Description

本考案は、作業現場などを囲繞するフェンスに設けられた作業車両の出入り口の扉体の開閉を行うゲート開閉装置に関するものである。   The present invention relates to a gate opening and closing device that opens and closes a door body at a doorway of a work vehicle provided on a fence surrounding a work site or the like.

ゲート開閉装置(扉体駆動装置)として種々の構成のものが知られているが、本考案は、ゲート上方に横架した駆動用螺軸に、扉体に螺軸回転を軸方向移動に変換する作動部を備えさせ、前記作動部を螺軸に螺合し、螺軸の回転で扉体の開閉移動を行う装置に係るものである。特にゲート間隔が広い場合、螺軸として、撓みが生じない程度の太径の丸棒から切削形成した棒状ネジ軸を採用したのではコスト高となってしまう。このため螺軸に替えて平鋼を螺旋状に形成したスパイラルロッド(螺旋ロッド)を採用することが提案されている(特許文献1)。   Although various types of gate opening / closing devices (door body drive devices) are known, the present invention converts the screw shaft rotation to axial movement in the door body to the drive screw shaft laid horizontally above the gate. The operation part is provided, and the operation part is screwed onto the screw shaft, and the door body is opened and closed by rotating the screw shaft. In particular, when the gate interval is wide, if a rod-like screw shaft formed by cutting a large-diameter round rod that does not cause bending is used as the screw shaft, the cost increases. For this reason, it has been proposed to adopt a spiral rod (spiral rod) in which flat steel is formed in a spiral shape instead of the screw shaft (Patent Document 1).

特開2008−223449号公報。Japanese Patent Application Laid-Open No. 2008-223449.

回転駆動軸として平鋼で螺旋状に形成したスパイラルロッド(螺旋ロッド)を採用した特許文献1に開示されている作動部は、螺旋ロッドに噛みあわせた移動子である。前記の移動子は、図示によると螺旋ロッドの螺旋面に当接することで噛みあわせを実現しているものである。即ち螺旋ロッドが回転すると、螺旋ロッドの螺旋面(平鋼板の表裏面)で移動子の当接面を擦りながら軸方向に押し出すものである。このため摩擦抵抗が扉体の開閉移動の抵抗となり、低コストの平鋼スパイラルロッドを採用しても開閉動作のスムーズ性が阻害される。   The operation unit disclosed in Patent Document 1 that employs a spiral rod (spiral rod) formed in a spiral shape with flat steel as a rotational drive shaft is a moving element meshed with the spiral rod. As shown in the drawing, the moving element is in contact with the spiral surface of the spiral rod to realize the meshing. That is, when the spiral rod rotates, it is pushed out in the axial direction while rubbing the contact surface of the moving element with the spiral surfaces (front and back surfaces of the flat steel plate) of the spiral rod. For this reason, the frictional resistance becomes the resistance of the opening and closing movement of the door body, and the smoothness of the opening and closing operation is hindered even if a low-cost flat steel spiral rod is adopted.

そこで本考案は、平鋼スパイラルロッドの回転を扉体の開閉駆動に変換する作動部を改良したゲート開閉装置を提案したものである。   In view of this, the present invention proposes a gate opening / closing device with an improved operating portion that converts the rotation of a flat steel spiral rod into the door body opening / closing drive.

本考案の請求項1記載に係るゲート開閉装置は、開閉可能に設けた扉の上方に、回転駆動部を付設した平鋼スパイラルロッドで形成された螺旋ロッドを横架すると共に、前記螺旋ロッドの回転を軸方向移動に変換する作動部を扉体に固着してなるゲート開閉装置において、作動部が、螺旋ロッドの軸方向と交る軸方向で、且つ前記螺旋ロッドの回転外周円より内側に進出して螺旋ロッドの外縁部と当接する自由回転軸体で構成してなることを特徴とするものである。   A gate opening and closing device according to claim 1 of the present invention horizontally spans a spiral rod formed of a flat steel spiral rod provided with a rotation drive unit above a door that can be opened and closed. In a gate opening and closing device in which an operating part for converting rotation to axial movement is fixed to a door body, the operating part is in an axial direction intersecting with the axial direction of the spiral rod and inside the rotational outer circumference of the spiral rod. It is composed of a free rotating shaft that advances and contacts the outer edge of the spiral rod.

而して螺旋ロッド(平鋼スパイラルロッド)を回転させると、自由回転軸体は、常に螺旋ロッドの外縁部に当接するので、自由回転軸体を備えた作動部は螺旋ロッドの回転に伴って軸方向に移動する。同時に作動部が設けられている扉体が移動し、ゲートの開閉動作を行うことになる。   Thus, when the spiral rod (flat steel spiral rod) is rotated, the free rotating shaft always comes into contact with the outer edge of the spiral rod, so that the operating portion having the free rotating shaft is accompanied by the rotation of the spiral rod. Move in the axial direction. At the same time, the door provided with the operating portion moves to open and close the gate.

また本考案の請求項2記載に係るゲート開閉装置は、自由回転軸体が、螺旋ロッドを挟んで一対で構成してなるもので、螺旋ロッドを挟む状態で装着されるので、扉体に開閉動作中に移動方向以外の外力が加わっても、自由回転軸体が螺旋ロッド外縁部から離れることなく、スムーズなゲート開閉がなされる。   In the gate opening and closing device according to claim 2 of the present invention, the free rotating shaft body is constituted by a pair of sandwiching the spiral rod, and is mounted in a state of sandwiching the spiral rod. Even when an external force other than the moving direction is applied during operation, the free rotating shaft body is smoothly opened and closed without leaving the outer edge of the spiral rod.

また本考案の請求項3記載に係るゲート開閉装置は、螺旋ロッドの中間から螺旋方向を逆転させ、螺旋方向の異なるロッドに各々扉体を設けてなるもので、螺旋ロッドの回転で左右の扉体が同時に開閉動作を行い、両開き・両閉じがなされる。   According to a third aspect of the present invention, there is provided a gate opening / closing device in which the spiral direction is reversed from the middle of the spiral rod, and doors are provided on the rods having different spiral directions. The body opens and closes at the same time, and opens and closes.

本考案は上記の構成で、ゲートの開閉駆動の回転軸として低コストの平鋼スパイラルロッドを採用しても、何ら支障なくスムーズなゲートの開閉動作を実現したものである。   The present invention achieves a smooth gate opening / closing operation without any trouble even if a low-cost flat steel spiral rod is used as the rotation shaft for the gate opening / closing drive.

次に本考案の実施形態について説明する。本考案のゲート開閉装置が適用されるゲートは、例えばフェンス01で囲繞された作業現場に設けられた出入口に、左右の支柱02と支柱間に扉用のレール03を備えた横架材04を架設し、扉体05の上方に突設した吊下げ腕06に戸車07を設け、戸車07をレール03に装着して扉体05を吊下げ、レール03に沿って扉体05が移動することで、ゲートの開閉を行うものである。   Next, an embodiment of the present invention will be described. The gate to which the gate opening and closing device of the present invention is applied is, for example, a horizontal member 04 provided with door rails 03 between left and right columns 02 and a column at a door provided at a work site surrounded by a fence 01. A door frame 07 is provided on a hanging arm 06 that is installed and protrudes above the door body 05, the door wheel 07 is mounted on the rail 03, the door body 05 is suspended, and the door body 05 moves along the rail 03. The gate is opened and closed.

ゲート開閉装置は、回転駆動部1と、ロッド部2と、作動部3で構成され、回転駆動部1は、一方の支柱02に装着された駆動モータ部(適宜な減速装置を備えている)11と、前記駆動モータ部11への電力供給のオンオフ並びに回転方向の制御を行う制御スイッチ部12を備えてなる。   The gate opening / closing device includes a rotation drive unit 1, a rod unit 2, and an operation unit 3. The rotation drive unit 1 includes a drive motor unit (equipped with an appropriate speed reduction device) attached to one of the columns 02. 11 and a control switch unit 12 for controlling on / off of the power supply to the drive motor unit 11 and the rotation direction.

ロッド部2は、中間に連結筒部21を設け、その左右に螺旋ロッド22a,22bを連結し、回転自在にレール03と平行に架設したものであり、螺旋ロッド22a,22bは、平鋼を螺旋状に捩じった平鋼スパイラルロッドで形成し、左右の螺旋ロッド22a,22bの螺旋方向を逆にしているものである。また中間の連結筒部21は横架材04に固定した軸受部23で支持されている。   The rod portion 2 is provided with a connecting cylinder portion 21 in the middle, and spiral rods 22a and 22b are connected to the left and right of the rod portion 2 and are rotatably mounted in parallel with the rail 03. The spiral rods 22a and 22b are made of flat steel. It is formed of a flat steel spiral rod twisted in a spiral shape, and the spiral directions of the left and right spiral rods 22a, 22b are reversed. The intermediate connecting cylinder portion 21 is supported by a bearing portion 23 fixed to the horizontal member 04.

作動部3は、固定ベース部31を、各扉体05の吊下げ腕06に設け、前記固定ベース部31にロッド部2と水平方向で直交する自由回転軸体32を設けたものである。   The actuating part 3 is provided with a fixed base part 31 on a hanging arm 06 of each door body 05 and a free rotating shaft 32 that is orthogonal to the rod part 2 in the horizontal direction on the fixed base part 31.

自由回転軸体32は、軸全体が自由回転するような構造でも、また固定軸の外側に自由回転する筒状体を外挿する構造でも良く、螺旋ロッド22a,22bの回転外周円より内側に位置すると共に、自由回転軸体32の外周面が螺旋ロッド22a,22bの外縁部と当接させてなり、特に自由回転軸体32は、螺旋ロッド22a,22bの上下を挟んで設けたものである。   The free rotating shaft body 32 may have a structure in which the entire shaft freely rotates, or may have a structure in which a cylindrical body that freely rotates outside the fixed shaft may be extrapolated, and the inner side of the rotating outer circumference of the spiral rods 22a and 22b. In addition, the outer peripheral surface of the free rotating shaft body 32 is in contact with the outer edge of the spiral rods 22a and 22b. In particular, the free rotating shaft body 32 is provided with the upper and lower sides of the spiral rods 22a and 22b interposed therebetween. is there.

而して制御スイッチ部12でゲート開閉指示のスイッチをオンとすると、駆動モータ部11が所定方向に回転駆動する。駆動モータ部11の回転によってロッド部2が回転し、ロッド部2の回転によって自由回転軸体32が螺旋ロッド22a,22bの外縁部で押し出されるので、自由回転軸体32が転がりながら軸方向に移動し、これによって扉体05が開閉動作(両開き・両閉じ)をなすものである。   Thus, when the control switch unit 12 turns on the gate opening / closing instruction switch, the drive motor unit 11 is driven to rotate in a predetermined direction. The rod portion 2 is rotated by the rotation of the drive motor portion 11, and the free rotating shaft body 32 is pushed out by the outer edge portions of the spiral rods 22a and 22b by the rotation of the rod portion 2, so that the free rotating shaft body 32 rolls in the axial direction while rolling. As a result, the door body 05 opens and closes (opens and closes both).

特に自由回転軸体32で螺旋ロッド22a,22bを上下から挟むように設けているものであるから。扉体05に開閉移動と関係ない外部の力、例えば扉体05を持ち上げる力などが加わっても、螺旋ロッド22a,22bから作動部3が外れることが無く、また両開き・両閉じ構造を採用することで、駆動モータ部11の駆動時間を短縮できるものである。   In particular, the free rotation shaft 32 is provided so as to sandwich the spiral rods 22a and 22b from above and below. Even if an external force unrelated to the opening / closing movement, for example, a force for lifting the door body 05, is applied to the door body 05, the operating portion 3 is not detached from the spiral rods 22a, 22b, and a double-open / double-close structure is adopted. Thus, the drive time of the drive motor unit 11 can be shortened.
