Description

本発明は、線材吊上げ式昇降ゲートに関するものである。   The present invention relates to a wire lifting type lifting gate.

高速道路等の自動車専用道路には、緊急車両や除雪車等の作業車両が沿線の一般道路からも直接アクセスできるように緊急進入路が設けられており、この緊急進入路の出入り口は、定常時は一般車両が進入できないようにゲート等で閉鎖していて、所定の車両が通過する際に、リモコン操作等でゲートを操作して出入り口を開放し、通過後、また、閉鎖状態に戻している。   Emergency roads are provided on motorways such as expressways so that work vehicles such as emergency vehicles and snow plows can be accessed directly from the general roads along the road. It is closed by a gate or the like so that a general vehicle cannot enter, and when a predetermined vehicle passes, the gate is opened by operating a remote controller or the like to open the doorway, and after passing, it is returned to the closed state.

この緊急進入路の出入り口に設置されるゲートは、従来、例えば特許文献１のような、巻き取りドラムから巻き出され上方から垂下させた線材で吊設したゲート体を出入り口に昇降自在に配設し、巻き取りドラムを回動させて線材を巻き取ることでゲート体を上昇させて出入り口を開放し、線材を巻き出すことでゲート体を下降させて出入り口閉鎖するように構成したものが一般的であった。   Conventionally, the gate installed at the entrance / exit of the emergency approach path is, for example, as disclosed in Patent Document 1, a gate body suspended from a winding drum and hung from above is hung up and down at the entrance / exit. It is generally configured to rotate the winding drum to wind up the wire, raise the gate body to open the entrance, and to unwind the wire to lower the gate body and close the entrance Met.

特開２００８−２９１５２８号公報JP 2008-291528 A

この従来の線材吊上げ式昇降ゲートは、ゲート体33を吊設する線材32はゲート体33の重みによって常に引き下げ付勢が生じて張設状態になっているが、図６に示すように、ゲート体33の下降軌道上に降り積もった雪や除雪によって生じた雪の塊等の障害物38が下降軌道上にあると、この障害物38にゲート体33が当接して所定の位置（最下点）まで下降しきらないうちに途中で停止してしまう。   In this conventional wire lifting type elevating gate, the wire 32 for suspending the gate body 33 is always in a tensioned state due to the weight of the gate body 33, and as shown in FIG. If an obstacle 38 such as snow piled up on the descending orbit of the body 33 or a snow lump caused by snow removal is on the descending orbit, the gate body 33 abuts on the obstacle 38 and the predetermined position (the lowest point) ) Stops halfway before descending.

この際、ゲート体33が途中で停止しても線材32の巻き出しは直ぐに停止せず、巻き取りドラム31は所定量の線材32を巻き出すまで停止しないため、巻き出された線材32分だけ線材32が弛んでしまい、この線材32が弛むことによって規則的に整列状態で巻き取りドラム31に巻かれている線材32が外方に広がり不規則な状態となり、この不規則な状態で線材32を巻き取ると乱巻になってしまい、引っ掛かりや線材32同士の絡みつきが生じて巻き取りドラム31の動作不良等、故障の原因となっていた。   At this time, even if the gate body 33 stops halfway, the unwinding of the wire 32 does not stop immediately, and the winding drum 31 does not stop until a predetermined amount of the wire 32 is unwound. When the wire 32 is loosened, the wire 32 wound around the winding drum 31 in a regularly aligned state spreads outwardly and becomes an irregular state due to the loosening of the wire 32, and the wire 32 is irregular in this irregular state. When the wire is wound up, it becomes a turbulent winding, and the wire rods 32 are caught or entangled with each other, causing malfunction such as malfunction of the winding drum 31.

本発明は、上述のような現状に鑑みなされたもので、ゲート体が下降軌道上に存在する障害物によって下降途中で停止しても、このゲート体を吊設している線材が弛まず乱巻が生じない実用性に優れた線材吊上げ式昇降ゲートを提供することを目的とする。   The present invention has been made in view of the current situation as described above, and even when the gate body is stopped in the middle of lowering by an obstacle present on the descending trajectory, the wire rod suspending the gate body is not disturbed. An object of the present invention is to provide a wire lifting type lifting gate excellent in practicality that does not cause winding.

添付図面を参照して本発明の要旨を説明する。   The gist of the present invention will be described with reference to the accompanying drawings.

In the wire lifting type lifting gate that lifts the gate body 3 by winding the wire 3 to open the entrance 5 and closes the entrance 5 by lowering the gate body 3 by unwinding the wire 2. 2 is provided with a retaining locking portion 6 that is latched to the gate body 3 when the wire body 2 is wound up and lifted and lifted and the wire body 2 is wound to prevent the retaining member. The stop portion 6 is engaged with the gate body 3, and the wire body 2 is further wound in a state in which the retaining portion 6 is engaged with the gate body 3, so that the gate body 3 is lifted and raised. Composed and drooped A weight 7 is provided on the material 2, and the wire 2 is configured to be pulled down and biased by the weight 7, and the wire 2 is held in a state where the retaining locking portion 6 is retained and locked to the gate body 3. When unwinding and lowering the gate body 3, even if the gate body 3 stops or lowers during the lowering due to the obstacle 8 existing on the descending trajectory of the gate body 3, the weight 7 The wire rod lifting and lowering gate is characterized in that the wire rod 2 does not sag by moving downward with the unwinding amount of the winding drum 1.

また、前記巻き取りドラム１の巻き出し動作を自動的に停止する自動巻き出し停止機構を備えたことを特徴とする請求項１記載の線材吊上げ式昇降ゲートに係るものである。   The wire lifting type lifting gate according to claim 1, further comprising an automatic unwinding stop mechanism that automatically stops unwinding operation of the winding drum 1.

また、前記線材２の下端部に設けた前記錘７の下方に、前記ゲート体３が下降途中で停止しても前記線材２の巻き出し動作に伴って前記錘７が下降移動可能な移動空間部９を設けたことを特徴とする請求項１，２のいずれか１項に記載の線材吊上げ式昇降ゲートに係るものである。   Further, below the weight 7 provided at the lower end portion of the wire 2, a moving space in which the weight 7 can move downward along with the unwinding operation of the wire 2 even when the gate body 3 stops in the middle of lowering. The wire rod lifting type lifting gate according to any one of claims 1 and 2, wherein a portion 9 is provided.

また、前記ゲート体３に、前記線材２に設けた抜け止め係止部６を受け止め係止する板状若しくは棒状に形成した受け止め部10を設けて、前記抜け止め係止部６がこの受け止め部10に点接触若しくは線接触状態で当接し係止する構成としたことを特徴とする請求項１〜３のいずれか１項に記載の線材吊上げ式昇降ゲートに係るものである。   Further, the gate body 3 is provided with a receiving portion 10 formed in a plate shape or a rod shape for receiving and locking the retaining locking portion 6 provided on the wire 2, and the retaining locking portion 6 is configured to receive this locking portion. It is set as the structure which contact | abuts and latches to 10 in a point contact or a line contact state, It concerns on the wire rod lifting type raising / lowering gate of any one of Claims 1-3 characterized by the above-mentioned.

本発明は上述のように構成したから、ゲート体を下降させて出入り口を閉鎖する際、ゲート体の下降軌道上に障害物が存在し、この障害物によってゲート体が下降途中で停止したり、或いは障害物が抵抗となってゲート体の下降速度が巻き取りドラムの線材を巻き出す速度よりも低下したりしても、巻き取りドラムから巻き出された線材に弛みが生じず、線材の張設状態が保持されるので、この巻き出した線材を次に巻き取る際に線材を規則正しく巻き取りドラムに巻きとることができ、よって、従来のように乱巻によって引っ掛かりや線材同士の絡みつきが生じて巻き取りドラムの動作不良等の故障が発生することがない実用性に優れた画期的な線材吊上げ式昇降ゲートとなる。   Since the present invention is configured as described above, when the gate body is lowered to close the doorway, there is an obstacle on the descending orbit of the gate body, and the obstacle stops the middle of the gate body by the obstacle, Alternatively, even if the obstacle acts as a resistance and the descending speed of the gate body is lower than the speed of unwinding the wire rod of the winding drum, the wire rod unwound from the winding drum does not sag, and the wire rod is not stretched.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

本発明は、ゲート体３を吊設した線材２を、巻き取りドラム１を回動させて巻き取り、巻き出しすることによって、入出ゲート４の出入り口５に配設したゲート体３を昇降させて出入り口５の開閉が行われる。   In the present invention, the wire body 2 suspended from the gate body 3 is wound up by rotating the winding drum 1 and unwound to move the gate body 3 disposed at the entrance / exit 5 of the entrance / exit gate 4 up and down. The doorway 5 is opened and closed.

具体的には、巻き取りドラム１を線材２の巻き取り方向に回動させてゲート体３を吊設した線材２を巻き取ると、この線材２に設けた抜け止め係止部６がゲート体３に係止し、この抜け止め係止部６がゲート体３に係止した状態で更に線材２を巻き取ると、抜け止め係止部６が上昇すると共にこの抜け止め係止部６がゲート体３を持ち上げて、このゲート体３を吊上げ上昇することで入出ゲート４の出入り口５を開放し、また、巻き取りドラム１を線材２の巻き出し方向に回動させてゲート体３を吊設した線材２を巻き出すと、抜け止め係止部６が下降し、この抜け止め係止部６の下降に伴い、ゲート体３は自重によって抜け止め係止部６に係止した状態で下降し入出ゲート４の出入り口５を閉鎖する。   Specifically, when the wire 2 with the gate body 3 suspended is wound by rotating the winding drum 1 in the winding direction of the wire 2, the retaining latching portion 6 provided on the wire 2 is used as the gate body 3. 3, and when the wire 2 is further wound up in a state where the retaining locking portion 6 is locked to the gate body 3, the retaining locking portion 6 rises and the retaining locking portion 6 is The body 3 is lifted and the gate body 3 is lifted and lifted to open the entrance / exit 5 of the entrance / exit gate 4 and the winding drum 1 is rotated in the unwinding direction of the wire 2 to suspend the gate body 3. When the wire 2 is unwound, the retaining latch 6 is lowered. As the retaining latch 6 is lowered, the gate body 3 is lowered while being locked to the retaining latch 6 by its own weight. The entrance / exit 5 of the entrance / exit gate 4 is closed.

また、ゲート体３を下降させて入出ゲート４の出入り口５を閉鎖する際、通常時は、巻き取りドラム１から巻き出される線材２の巻き出し量に応じてゲート体３が下降してゆき、例えば所定の巻き出し量に達したり所定の巻き出し時間が経過すると、巻き取りドラム１の回動が停止してこの巻き取りドラム１からの線材２の巻き出し動作が停止することでゲート体３の下降が停止することとなるが、ゲート体３の下降軌道上に例えば降り積もった雪や除雪によって生じた雪の塊等の障害物８があると、ゲート体３はこの障害物８に当接して所定の巻き出し量や所定の巻き出し時間に達する前、即ち巻き取りドラム１からの線材２の巻き出し動作が停止しないうちに停止してしまったり或いは障害物８が抵抗となって下降速度が低下したりしてしまう。   Further, when the gate body 3 is lowered to close the entrance / exit 5 of the entry / exit gate 4, the gate body 3 is lowered according to the amount of unwinding of the wire 2 unwound from the winding drum 1, at normal times. For example, when a predetermined unwinding amount is reached or a predetermined unwinding time elapses, the rotation of the winding drum 1 is stopped, and the unwinding operation of the wire 2 from the winding drum 1 is stopped, whereby the gate body 3 is stopped. However, if there is an obstacle 8 such as snow piled up on the descending track of the gate body 3 or a snow lump caused by snow removal, the gate body 3 comes into contact with the obstacle 8. Before reaching a predetermined unwinding amount or a predetermined unwinding time, that is, before the unwinding operation of the wire 2 from the winding drum 1 stops, or the obstacle 8 acts as a resistance and the lowering speed Or drop Mau.

このような状況になると、従来は、図６に示すように、線材32が弛んで巻き取りドラム31に巻かれている線材32が不規則に広がってしまい次の巻き取りで乱巻になって引っ掛かりや線材32同士の絡みが生じて巻き取りドラム31の巻き取り動作不良等の不具合が生じてしまうが、本発明は、ゲート体３を吊設した線材２が、このゲート体３に固定されておらず抜け止め状態に設けたので、ゲート体３が障害物８によって下降途中で停止しても、線材２の下端部、具体的には線材２に設けた抜け止め係止部６は下降し続けることができ、しかも、本発明の線材２は、この線材２に設けた錘７による引き下げ付勢がこの線材２の張力となって常にこの線材２を張設状態に保持しているので、巻き取りドラム１が線材２を巻き出している途中でゲート体３が停止したり下降速度が低下したりしてこの線材２とゲート体３との係止状態が解除されてこのゲート体３の重みによる引き下げ付勢がなくなっても、この線材２に設けた錘７が巻き取りドラム１の巻き出し量に伴って下降移動することで、この線材２を引き下げ付勢して上方から垂下させた線材２に張設付勢を付与して張設状態を保持することとなり、巻き取りドラム１が線材２を巻き出している途中でゲート体３が停止したり下降速度が低下したりしても、巻き取りドラム１から巻き出され上方から垂下させた線材２は弛みを生じることなく張設状態を保持したまま巻き出されることとなる。   In such a situation, conventionally, as shown in FIG. 6, the wire 32 is loosened and the wire 32 wound around the take-up drum 31 spreads irregularly, resulting in random winding in the next winding. However, the wire rod 2 in which the gate body 3 is suspended is fixed to the gate body 3 in the present invention. Even if the gate body 3 is stopped by the obstacle 8 in the middle of being lowered, the lower end portion of the wire 2, specifically, the retainer locking portion 6 provided on the wire 2 is lowered. In addition, the wire 2 according to the present invention always keeps the wire 2 in the tensioned state because the pulling force by the weight 7 provided on the wire 2 becomes the tension of the wire 2. In the middle of the winding drum 1 unwinding the wire 2, the gate body 3 Even if the wire 2 and the gate body 3 are released from the locked state due to the stoppage or the lowering speed being reduced, and the downward biasing force due to the weight of the gate body 3 disappears, the weight provided on the wire 2 7 moves downward along with the amount of unwinding of the take-up drum 1, so that the wire 2 is pulled down and biased from above to give a tensioning force to maintain the tensioned state. Thus, even if the gate body 3 stops or the lowering speed decreases while the winding drum 1 is unwinding the wire 2, the wire 2 unwound from the winding drum 1 and suspended from above is It will be unwound while maintaining the tensioned state without causing slack.

このように、本発明は、巻き取りドラム１が線材２を巻き出している途中でゲート体３が停止したり下降速度が低下したりしても、線材２に弛みが生じないので、巻き取りドラム１に巻かれている線材２も不規則に広がらず規則正しく整列した状態が維持され、次の上昇動作の巻き取り時に乱巻が生じず、引っ掛かりや線材２同士の絡みによる巻き取りドラム１の動作不良等の故障が発生することがない実用性に優れた画期的な線材吊上げ式昇降ゲートとなる。   Thus, the present invention does not cause slack in the wire 2 even if the gate body 3 stops or the lowering speed decreases while the winding drum 1 is unwinding the wire 2. The wire 2 wound around the drum 1 does not spread irregularly and is kept in a regularly aligned state, and no turbulent winding occurs during winding of the next ascending operation. It becomes an epoch-making wire-lifting lift gate with excellent practicality that does not cause malfunction such as malfunction.

本発明の具体的な実施例について図面に基づいて説明する。   Specific embodiments of the present invention will be described with reference to the drawings.

本実施例は、巻き取りドラム１から巻き出され上方から垂下させた線材２で吊設したゲート体３を入出ゲート４の出入り口５に昇降自在に配設し、前記巻き取りドラム１を回動させて前記線材２を巻き取ることで前記ゲート体３を上昇させて出入り口５を開放し、前記線材２を巻き出すことで前記ゲート体３を下降させて前記出入り口５を閉鎖する線材吊上げ式昇降ゲートにおいて、前記線材２に、この線材２を巻き取って前記ゲート体３を吊上げ上昇する際にこのゲート体３に係止する抜け止め係止部６を設けて、この線材２を巻きとることで前記抜け止め係止部６が前記ゲート体３に係止し、この抜け止め係止部６が前記ゲート体３に係止した状態で更に前記線材２を巻き取ることで、このゲート体３を吊上げ上昇するように構成し、前記垂下させた線材２に錘７を設けて、前記線材２をこの錘７により引き下げ付勢するように構成し、前記ゲート体３に前記抜け止め係止部６を抜け止め係止した状態で前記線材２を巻き出して前記ゲート体３を下降させてゆく際、このゲート体３の下降軌道上に存在する障害物８によって前記ゲート体３が下降途中で停止若しくは下降速度が低下しても、前記錘７が前記巻き取りドラム１の巻き出し量に伴って下降移動することで前記線材２に弛みが生じないように構成した線材吊上げ式昇降ゲートである。   In this embodiment, a gate body 3 suspended from a wire 2 unwound from the take-up drum 1 and suspended from above is disposed at the entrance / exit 5 of the entrance / exit gate 4 so as to be movable up and down, and the take-up drum 1 is rotated. The wire body 2 is wound up to raise the gate body 3 to open the entrance / exit 5, and the wire 2 is unwound to lower the gate body 3 to close the entrance / exit 5. In the gate, the wire 2 is wound around the wire 2 and provided with a retaining locking portion 6 that is locked to the gate body 3 when the gate body 3 is lifted and lifted, and the wire 2 is wound up. In this state, the retaining member 6 is locked to the gate body 3, and the wire member 2 is further wound while the retaining member 6 is locked to the gate body 3. Configured to lift and lift A weight 7 is provided on the suspended wire 2, and the wire 2 is configured to be pulled down and biased by the weight 7. In the state where the retaining locking portion 6 is retained and locked to the gate body 3. When the wire body 2 is unwound and the gate body 3 is lowered, even if the gate body 3 is stopped or lowered at a lower speed due to the obstacle 8 on the descending orbit of the gate body 3, It is a wire lifting hoisting gate configured such that the wire 7 does not slack due to the weight 7 moving downward with the winding amount of the winding drum 1.

具体的には、本実施例の巻き取りドラム１の巻き取り、巻き出し動作は、電動モータを用いた駆動部11によって行われ、操作リモコンの上昇スイッチをオンすると、駆動部11が駆動しこれに連動して巻き取りドラム１が回動して線材２を巻き取り、巻き出ししてゲート体３を昇降させる構成としている。   Specifically, the winding and unwinding operations of the winding drum 1 of this embodiment are performed by the driving unit 11 using an electric motor. When the raising switch of the operation remote controller is turned on, the driving unit 11 is driven and this operation is performed. The winding drum 1 rotates in conjunction with the winding to wind up the wire 2 and unwind it to raise and lower the gate body 3.

また、本実施例は、巻き取りドラム１の巻き取り動作を自動的に停止する自動巻き取り停止機構と、巻き取りドラム１の巻き出し動作を自動的に停止する自動巻き出し停止機構との両方を備えた巻き取りドラム動作制御機構を備えた構成とし、この巻き取りドラム１の巻き取り、巻き出し動作を作業者が操作することなく自動的に停止するように構成している。   Further, in this embodiment, both an automatic winding stop mechanism that automatically stops the winding operation of the winding drum 1 and an automatic winding stop mechanism that automatically stops the winding operation of the winding drum 1. The take-up drum operation control mechanism is provided, and the take-up and unwind operations of the take-up drum 1 are automatically stopped without the operator's operation.

具体的には、自動巻き取り停止機構は、二つのセンサ（減速センサ12と停止センサ13）とシーケンサで構成し、上昇してきたゲート体３を下方側に設けた減速センサ12が検知すると、シーケンサによって巻き取りドラム１を回動する駆動部11が減速して巻き取りドラム１の回動動作速度が低下してゲート体３の上昇速度を低下させ、この上昇速度が減速したゲート体３を減速センサの上方に設けた二つ目の停止センサ13がゲート体３を検知すると、シーケンサによって駆動部11の動作を停止させて巻き取り動作を停止させることでゲート体３の上昇を自動的に停止する構成としている。   Specifically, the automatic winding stop mechanism is composed of two sensors (deceleration sensor 12 and stop sensor 13) and a sequencer. When the deceleration sensor 12 provided on the lower side of the rising gate body 3 detects the sequencer As a result, the drive unit 11 that rotates the take-up drum 1 is decelerated, the turning operation speed of the take-up drum 1 is reduced, and the rising speed of the gate body 3 is reduced. When the second stop sensor 13 provided above the sensor detects the gate body 3, the operation of the drive unit 11 is stopped by the sequencer and the winding operation is stopped by the sequencer to automatically stop the raising of the gate body 3. It is configured to do.

また、自動巻き出し停止機構は、一つのセンサ（減速センサ14）とシーケンサとタイマで構成し、下降してきたゲート体３を減速センサ14が検知すると、シーケンサによって巻き取りドラム１を回動する駆動部11が減速して巻き取りドラム１の回動動作速度が低下してゲート体３の下降速度を低下させると共に、タイマを始動させて、このタイマの設定時間が経過したら、駆動部11の動作を停止させて巻き取り動作を停止させることでゲート体３の下降を自動的に停止する構成としている。   The automatic unwinding stop mechanism is composed of one sensor (deceleration sensor 14), a sequencer, and a timer. When the deceleration sensor 14 detects the descending gate body 3, the sequencer drives the winding drum 1 to rotate. When the part 11 is decelerated and the rotating speed of the winding drum 1 is lowered to lower the descending speed of the gate body 3 and the timer is started and the set time of this timer has elapsed, the operation of the drive part 11 The descent of the gate body 3 is automatically stopped by stopping the winding and stopping the winding operation.

このゲート体３の縦フレーム17は、中空構造の角形フレームで上面部にこのゲート体３を吊設する線材２を挿通し得る挿通孔20を形成し、更に、この挿通孔20を形成した上面部の裏面に後述する抜け止め係止部６を受け止め係止する受け止め部10を設けた構成としている。   The vertical frame 17 of the gate body 3 is a hollow square frame, and has an upper surface formed with an insertion hole 20 through which the wire 2 for suspending the gate body 3 can be inserted. Further, the upper surface on which the insertion hole 20 is formed. A receiving portion 10 for receiving and locking a retaining locking portion 6 described later is provided on the back surface of the portion.

具体的には、この受け止め部10は、板状若しくは棒状に形成して縦フレーム17の上面部裏面に垂設し、抜け止め係止部６がこの受け止め部10の端面に点接触若しくは線接触状態で当接し係止するように構成しており、本実施例では、この受け止め部10を円筒状に形成して、縦フレーム17の上面部に形成した挿通孔20を囲うように配設した構成としている。   Specifically, the receiving portion 10 is formed in a plate shape or a rod shape and is suspended from the back surface of the upper surface portion of the vertical frame 17, and the retaining locking portion 6 is in point contact or line contact with the end surface of the receiving portion 10. In this embodiment, the receiving portion 10 is formed in a cylindrical shape so as to surround the insertion hole 20 formed in the upper surface portion of the vertical frame 17. It is configured.

また、本実施例では、この縦フレーム17の内部に後述する錘７が下降移動可能な移動空間部９を備えると共に、錘７の昇降移動をガイドするガイド体21を設けて、この錘７が移動空間部９を下降する際、このガイド体21に沿設状態に下降することによって移動空間部９を錘７がふらつくことなく垂直に下降するように構成としている。   Further, in this embodiment, a moving space portion 9 in which a weight 7 described later can move downward is provided inside the vertical frame 17, and a guide body 21 for guiding the lifting and lowering movement of the weight 7 is provided. When the moving space portion 9 is lowered, the moving space portion 9 is lowered vertically without the wobbling of the weight 7 by being lowered along the guide body 21.

更に、本実施例は、このゲート体３の左右の縦フレーム17に補助スライド体22を設け、ゲート体３が昇降する際、この補助スライド体22が入出ゲート４の支柱15をスライドガイド部として沿設状態にスライド走行移動することでゲート体３が前後左右方向にふらつくことなく安定して昇降移動するように構成している。   Further, in this embodiment, auxiliary slide bodies 22 are provided on the left and right vertical frames 17 of the gate body 3, and when the gate body 3 moves up and down, the auxiliary slide body 22 uses the column 15 of the entrance / exit gate 4 as a slide guide portion. The gate body 3 is configured to move up and down stably without sliding in the front-rear and left-right directions by sliding and moving in the side-by-side state.

また更に、本実施例のゲート体３は、上下方向に対向配設した一対の横フレーム18の下方側に、複数の方形状に形成した小動物進入防止シート23を垂設して、下降して入出ゲート４の出入り口５を閉鎖した状態において、ゲート体３の下側横フレーム18と地面との間に生じる隙間からのタヌキ等の小動物の侵入を防止する構成としている。   Furthermore, the gate body 3 of the present embodiment is lowered by hanging a small animal intrusion prevention sheet 23 formed in a plurality of square shapes below the pair of horizontal frames 18 arranged opposite to each other in the vertical direction. In a state where the entrance / exit 5 of the entrance / exit gate 4 is closed, a small animal such as a raccoon dog is prevented from entering from a gap formed between the lower lateral frame 18 of the gate body 3 and the ground.

尚、本実施例の小動物進入防止シート23は、柔軟性を有する合成樹脂で形成し、ゲート体３が下降する際に、この小動物進入防止シート23が障害物８に当接しても、この小動物進入防止シート23が変形することによってゲート体３がこの小動物進入防止シート23の変形した分だけ下降し得るように構成している。   The small animal entry prevention sheet 23 of this embodiment is formed of a flexible synthetic resin. Even when the small animal entry prevention sheet 23 comes into contact with the obstacle 8 when the gate body 3 is lowered, the small animal entry prevention sheet 23 is formed. The gate body 3 can be lowered by the amount of deformation of the small animal entry prevention sheet 23 by the deformation of the entry prevention sheet 23.

このように構成した本実施例のゲート体３は、入出ゲート４の左右両側の上方から垂下した二本の線材２で吊設した構成としている。   The gate body 3 of the present embodiment configured as described above is configured to be suspended by two wire rods 2 suspended from the upper left and right sides of the input / output gate 4.

このゲート体３を吊設する二本の線材２の内の一方の線材２は、入出ゲート４の下方側若しくはこの入出ゲート４の近傍に設置した巻き取りドラム１から入出ゲート４の一側（巻き取りドラム１を設けた側）の支柱15に沿って上方に向けて巻き出し、この支柱15の上部に設けた滑車24Ａ及び滑車24Ｂによって下方に向けて折り返し垂下し、下端部をゲート体３の一方の縦フレーム17の上面部に形成した挿通孔20に挿通している。   One wire 2 out of the two wires 2 suspending the gate body 3 is placed on one side of the entry / exit gate 4 from the take-up drum 1 installed below or near the entry / exit gate 4 ( Unwinds upward along the support column 15 on the side where the take-up drum 1 is provided), hangs downward by a pulley 24A and a pulley 24B provided on the upper portion of this support column 15, and lowers the lower end portion of the gate body 3 One of the vertical frames 17 is inserted through an insertion hole 20 formed in the upper surface portion.

また、もう一方の線材２は、出ゲート４の下方側若しくはこの入出ゲート４の近傍に設置した巻き取りドラム１から入出ゲート４の一側（巻き取りドラム１を設けた側）の支柱15に沿って上方に向けて巻き出し、この支柱15の上部に設けた滑車24Ａによって直交方向に向きを変え、横架材16に沿って反対側のもう一方の支柱15の上部に設けた滑車24Ｃによって垂直方向に向きを変えて垂下し、下端部をゲート体３のもう一方の縦フレーム17の上面部に形成した挿通孔20に挿通している。   The other wire 2 is fed from a take-up drum 1 installed on the lower side of the exit gate 4 or in the vicinity of the entrance / exit gate 4 to a column 15 on one side of the entrance / exit gate 4 (the side where the take-up drum 1 is provided). Unwinding upward along the rail, the direction is changed in the orthogonal direction by a pulley 24A provided on the upper portion of the column 15, and a pulley 24C provided on the other column 15 on the opposite side along the horizontal member 16. The direction is lowered in the vertical direction, and the lower end portion is inserted through an insertion hole 20 formed in the upper surface portion of the other vertical frame 17 of the gate body 3.

本実施例では、このゲート体３の左右の縦フレーム17内に挿通した夫々の線材２に抜け止め係止部６と錘７とを設けて、この抜け止め係止部６によってゲート体３に挿通した線材をゲート体３に対して抜け止め状態に設けると共に、この下端部に設けた錘７によって線材２を引き下げ付勢してこの線材２に常時、張設付勢が付与されるように構成している。   In the present embodiment, a retaining locking portion 6 and a weight 7 are provided on each wire 2 inserted into the left and right vertical frames 17 of the gate body 3, and the retaining body 6 is attached to the gate body 3 by the retaining locking portion 6. The inserted wire is provided so as not to be detached from the gate body 3, and the wire 2 is pulled down and biased by the weight 7 provided at the lower end so that the wire 2 is always provided with tension. It is composed.

即ち、従来は、線材２がゲート体３に固定状態に設けられていて、更に、この線材２で吊設するゲート体３の重みによって線材２が引き下げ付勢されて線材２に張設付勢が付与されることで線材２の張設状態が保持される構成であったため、異常事態、例えばゲート体３の下降軌道上に障害物８が存在し、この障害物８によってゲート体３が下降途中で停止したり、この障害物８が抵抗となってゲート体３の下降速度が巻き取りドラム１の線材２を巻き出す速度よりも低下したりしてゲート体３の重みによる引き下げ付勢がなくなると、線材２の張設状態が解除されて線材２に弛みが生じて巻き取りドラム１に巻かれている線材２が不規則に広がって乱巻が生じる原因となっていたが、本実施例は、定常時においては、ゲート体３と錘７との両者の重みによって線材２に張設付勢を付与して線材２の張設状態を保持し、また、異常事態でゲート体３の引き下げ付勢が無くなっても、線材２をゲート体３に対して抜け止め状態に設けたことで、この線材２の下端部に設けた錘７がゲート体３の縦フレーム17に設けた移動空間部９を下降しながらこの線材２を引き下げ付勢して線材２に張設付勢を付与し、これによって、線材２は張設状態を保持して弛むことがない構成としている。   That is, conventionally, the wire 2 is fixedly attached to the gate body 3, and the wire 2 is further urged down by the weight of the gate body 3 suspended by the wire 2, and the wire 2 is stretched and urged Since the stretched state of the wire 2 is maintained by the application of an obstacle, there is an obstacle 8 on the descending orbit of the gate body 3, for example, and the gate body 3 is lowered by the obstacle 8. The obstacle 8 acts as a resistance, and the lowering speed of the gate body 3 is lower than the speed at which the wire 2 of the winding drum 1 is unwound. When the wire rod 2 disappears, the tension state of the wire rod 2 is released, the wire rod 2 is slackened, and the wire rod 2 wound around the take-up drum 1 spreads irregularly, causing irregular winding. The example shows that the gate body 3 and the weight 7 A tension is applied to the wire 2 by the weight of the person to maintain the tension state of the wire 2, and the wire 2 is attached to the gate body 3 even if the gate body 3 is not pulled down due to an abnormal situation. Since the weight 7 provided at the lower end of the wire 2 descends the moving space portion 9 provided in the vertical frame 17 of the gate body 3, the wire 2 is pulled down and biased by being provided in the retaining state. A tension is applied to 2 so that the wire 2 is kept in a tensioned state and does not loosen.

また、このゲート体３の縦フレーム17に設けた移動空間部９は、錘７が下降可能なスペースが狭いと、巻き取りドラム１からの線材２の巻き出し動作が停止しないうちに錘７がゲート体３の縦フレーム17の底面に到達して下降が停止してしまい、この錘７が停止した以降に巻き出された線材２の分だけ線材２が弛んでしまい乱巻の原因となってしまう為、できるだけ錘７が長い距離を下降することが可能なスペースに設定することが好ましく、本実施例では、上述したように、ゲート体３の下降は自動巻き出し停止機構の減速センサ14の検知によって始動したタイマの設定時間が経過すると自動的に停止する構成としたので、このタイマに設定した時間で巻き取りドラム１から巻き出される線材２の長さ分だけ錘７が下降することができるスペースに設定して、下降時に、この減速センサ14をゲート体３が通過してから停止するまでの間に、障害物８によってこのゲート体３の下降が途中停止しても、タイマが停止する前に錘７が縦フレーム17の底面に到達して下降を停止することなくタイマが停止するまで移動空間部９を下降し続けて、線材２の張設状態を保持して線材２に弛みが生じないように構成している。   Further, in the moving space portion 9 provided in the vertical frame 17 of the gate body 3, if the space in which the weight 7 can be lowered is narrow, the weight 7 is moved before the unwinding operation of the wire 2 from the winding drum 1 is stopped. The descent stops after reaching the bottom surface of the vertical frame 17 of the gate body 3, and the wire 2 is loosened by the amount of the wire 2 that has been unwound after the weight 7 is stopped, causing a turbulent winding. Therefore, it is preferable to set a space in which the weight 7 can descend a long distance as much as possible. In this embodiment, as described above, the gate body 3 is lowered by the deceleration sensor 14 of the automatic unwinding stop mechanism. Since it is configured to automatically stop when the set time of the timer started by the detection elapses, the weight 7 may be lowered by the length of the wire 2 to be unwound from the winding drum 1 in the time set in this timer. Spice that can When the gate body 3 passes through the deceleration sensor 14 and stops, the timer stops even if the gate body 3 descends due to the obstacle 8 during the downward movement. Before the weight 7 reaches the bottom surface of the vertical frame 17 and the timer stops without stopping the descent, the moving space portion 9 continues to descend, the tension state of the wire 2 is maintained and the wire 2 is slackened. It is configured not to occur.

尚、移動空間部９のスペースを上記のように設定できなくても、この移動空間部９を錘７が下降可能なスペースがあることによって、この錘７が下降した分だけ線材２の弛みが緩和されて、乱巻の発生を抑制する効果は生じることとなる。   Even if the space of the moving space portion 9 cannot be set as described above, there is a space in which the weight 7 can be lowered in the moving space portion 9, so that the wire 2 is slackened by the amount that the weight 7 is lowered. It is relaxed and the effect of suppressing the occurrence of turbulence occurs.

本実施例は、以上のように構成したので、以下のような作用・効果を発揮する。   Since the present embodiment is configured as described above, the following actions and effects are exhibited.

入出ゲート４の出入り口５の開放は、リモコン操作によって駆動部11を駆動させ巻き取りドラム１を線材２の巻き取り方向に回動させてゲート体３を吊設した線材２を巻き取ることで、この線材２に設けた抜け止め係止部６がゲート体３の縦フレーム17の受け止め部10に係止し、この抜け止め係止部６が受け止め部10に係止した状態で更に線材２を巻き取ることで、抜け止め係止部６が上昇すると共にこの抜け止め係止部６がゲート体３を持ち上げてこのゲート体３を吊上げ上昇させ、この上昇したゲート体３を入出ゲート４の支柱15に設けた減速センサ12が検知すると、シーケンサによって駆動部11の駆動速度が低下してゲート体３の上昇速度を減速させ、この上昇速度が減速したゲート体３を停止センサ13が検知することで、駆動部11に停止信号が行き、動作を停止して巻き取りが停止することでゲート体３の上昇が自動定期に停止して完了する。   The entrance / exit 5 of the entrance / exit gate 4 is opened by driving the drive unit 11 by a remote control operation and rotating the take-up drum 1 in the take-up direction of the wire 2 to wind up the wire 2 in which the gate body 3 is suspended. The retaining locking part 6 provided on the wire 2 is locked to the receiving part 10 of the vertical frame 17 of the gate body 3, and the wire 2 is further held in a state where the retaining locking part 6 is locked to the receiving part 10. By winding up, the retaining latching portion 6 rises and the retaining latching portion 6 lifts the gate body 3 and lifts and raises the gate body 3. When the deceleration sensor 12 provided in 15 detects, the sequencer decreases the drive speed of the drive unit 11 to decelerate the ascending speed of the gate body 3, and the stop sensor 13 detects the gate body 3 whose ascent speed is decelerated. The stop signal is sent to the drive unit 11. But go, complete stop rise of the gate body 3 to automatic regular by winding to stop the operation is stopped.

また、入出ゲート４の出入り口５の閉鎖は、リモコン操作によって駆動部11を駆動させ巻き取りドラム１を線材２の巻き出し方向に回動させてゲート体３を吊設した線材２を巻き出すことで抜け止め係止部６を下降させると、この抜け止め係止部６の下降に伴いゲート体３が自重によって抜け止め係止部６に係止した状態で下降し、この下降するゲート体３を入出ゲート４の支柱15の下方側に設けた減速センサ14が検知して、シーケンサによって駆動部11の駆動速度が低下してゲート体３の下降速度が減速すると共に、タイマが始動して、このタイマの設定時間が経過したら、駆動部11が停止して巻き取り動作が停止することでゲート体３の下降が自動的に停止して完了する。   Moreover, closing the entrance / exit 5 of the entrance / exit gate 4 unwinds the wire 2 which suspended the gate body 3 by driving the drive part 11 by remote control operation, rotating the winding drum 1 in the unwinding direction of the wire 2. When the retaining latching portion 6 is lowered, the gate body 3 descends in a state of being latched to the retaining latching portion 6 by its own weight as the retaining latching portion 6 descends. Is detected by the deceleration sensor 14 provided on the lower side of the column 15 of the entrance / exit gate 4, and the sequencer lowers the drive speed of the drive unit 11 to reduce the descending speed of the gate body 3, and the timer starts. When the set time of the timer elapses, the driving unit 11 stops and the winding operation stops, so that the lowering of the gate body 3 is automatically stopped and completed.

また、このゲート体３が下降する際に、ゲート体３の下降軌道上に例えば降り積もった雪や除雪によって生じた雪の塊等の障害物８があり、ゲート体３が減速センサ14を通過してからタイマの設定時間が経過して所定の位置で停止するまでの間に、この障害物８に当接して途中で停止してしまっても、巻き取りドラム１から巻き出された線材２は、この線材２の下端部に設けた錘７が巻き取りドラム１の巻き出し量に伴って下降移動することで、この錘７の引き下げ付勢により張設付勢が付与されて張設状態を保持したまま巻き出され、しかも、自動巻き出し停止機構のタイマに設定した時間が経過して駆動部11が停止するまで錘７が移動空間部９を下降し続けることが可能なので、巻き取りドラム１の巻き出し動作が停止するまで線材２の張設状態は保持されたまま巻き出されることとなる。   Further, when the gate body 3 is lowered, there are obstacles 8 such as snow piled up on the descending trajectory of the gate body 3 or a snow lump caused by snow removal, and the gate body 3 passes through the deceleration sensor 14. The wire 2 unwound from the take-up drum 1 is not contacted with the obstacle 8 until it stops at a predetermined position after the set time of the timer elapses. The weight 7 provided at the lower end of the wire 2 moves downward with the unwinding amount of the take-up drum 1, so that the tension is applied by the pulling-down bias of the weight 7 so that the tensioned state is maintained. Since the weight 7 can continue to move down the moving space 9 until the drive unit 11 stops after the time set in the timer of the automatic unwinding stop mechanism has elapsed, the winding drum can be wound. Tension of the wire 2 until the unwinding operation of 1 stops The installed state is unwound while being held.

従って、ゲート体３が下降する際、障害物８等によりゲート体３が途中で停止してこのゲート体３による引き下げ付勢が解除されても、線材２は錘７によって引き下げ付勢が作用して弛みが生じず張設状態が保持されるので、巻き取りドラム１に巻かれている線材２も不規則に広がらず規則正しく整列した状態が維持され、ゲート体３が下降途中で停止した次の上昇動作の巻き取り時に乱巻が生じず、引っ掛かりや線材２同士の絡みによる巻き取りドラム１の動作不良等の不具合が発生することがない実用性に優れた画期的な線材吊上げ式昇降ゲートとなる。   Accordingly, when the gate body 3 is lowered, even if the gate body 3 stops halfway due to the obstacle 8 or the like and the downward biasing force by the gate body 3 is released, the wire 2 is subjected to the downward biasing force by the weight 7. Since the slack does not occur and the tensioned state is maintained, the wire 2 wound around the take-up drum 1 is not irregularly spread and is kept in a regularly aligned state. A breakthrough wire lifting hoisting gate with excellent practicality that does not cause turbulent winding during winding of the ascending operation, and does not cause problems such as catching or malfunction of the winding drum 1 due to entanglement between the wires 2 It becomes.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
