Description

【０００１】
【発明の属する技術分野】
本発明は乗物検査設備及び乗物移動装置に係り、特に荷物を積載したトレーラやトラック等の重量物の乗物検査設備及び乗物移動装置に関するものである。
【０００２】
【従来の技術】
従来の検査設備としては、ＥＰ０４９１９７７Ａ１公報に記載のような、トレーラやトラック等の牽引ルートの牽引方向に直行する方向の両サイドにピットを設け、該両サイドのピット部にそれぞれ牽引装置を配置し、両サイドからトレーラやトラック等のタイヤを保持し、牽引装置を移動させてトレーラやトラック等を移動搬送するものが知られている。
【０００３】
【発明が解決しようとする課題】
上記の従来技術は、両サイドへのピットの設置により、ピットが２箇所になるとともに重量物が載る部分のフロアがカンチレバー構造となっており、充分な強度を持たせる必要があり、土木工事の負担増や、両サイドへの牽引装置配置で装置自体も２台必要になるとともに２台の同期運転制御が必要となり、複雑になるという問題がある。
【０００４】
本発明の目的は、検査ライン下側に設けられる検査物の移動用搬送装置を配置するピットの土木工事の負担を軽減することのできる乗物検査設備及び乗物移動装置を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的は、搬入，検査，搬出の一連の建屋内の乗物移動ラインの中央下側で、乗物の下方から乗物の前輪をアームにより保持し、昇降装置によってアームを昇降させ、昇降装置が取付けられた台車を走行装置によって乗物移動ラインの下方のガイドレールに沿って搬入建屋から搬出建屋へ移動させ、旋回装置によってアームの長手方向の向き全体を回転させて方向転換し、走行方向に対する直角方向の幅寸法を狭くして、搬出建屋から搬入建屋方向へ移動制御される乗物移動装置を用いることにより、達成される。
【０００６】
【発明の実施の形態】
以下、本発明の一実施例を図１から図８によって説明する。まず、図８に検査設備の全体概要を示す。１は検査建屋であり、２は搬入建屋であり、３は搬出建屋であり、一連の建屋となっている。搬入建屋２，検査建屋１，搬出建屋３の走行フロア４の中央下部にはピット５が設けられ、ピット５の底面には搬入建屋２から搬出建屋３に至るガイドレール６が敷設してある。ガイドレール６上には搬送装置１０が配置され、ガイドレール６上を長手方向に往復動する。検査建屋１の上部にはＸ線照射装置７が設けられ、Ｘ線照射装置７に対向してピット５下部にＸ線受光装置８が設けられて、垂直Ｘ線検査装置が構成される。検査建屋１内の垂直Ｘ線検査装置近傍には水平Ｘ線検査装置９が設置されている。
【０００７】
乗物である、この場合、トレーラ２０は、走行フロア４上を走行し、搬入建屋２内の所定の位置Ａ点で停止し、運転者はここでトレーラから離れる。運転者が搬入建屋から離れたことを確認し、搬入建屋２と検査建屋１との間の仕切りが開き、搬送装置１０がトレーラ２０の前輪を保持して検査建屋２方向に移動を開始する。搬送装置１０の移動によってトレーラ２０の最後尾が検査建屋１内に入ったことを確認して、搬入建屋２と検査建屋１との間の仕切りを閉める。トレーラ２０が検査建屋１内の所定位置に来たら垂直、水平Ｘ線検査装置が作動を開始し、トレーラ２０は所定の速度で通過する。トレーラ２０がＸ線検査装置を通過したら、Ｘ線の照射が停止され、検査建屋１と搬出建屋３との間の仕切りが開き、搬送装置１０がトレーラ２０を搬出建屋３内の所定の停止位置Ｂ点まで移動させる。搬送装置１０がトレーラ２０の前輪保持を解除したことを確認して、運転者はトレーラ２０に乗り込み、トレーラ２０を搬出建屋から運び出す。
【０００８】
なお、搬入建屋２からトレーラ２０が移動して、搬入建屋２内にトレーラ２０がいなくなれば、新たなトレーラの持込が可能となり、順次検査処理が実行される。
【０００９】
次に、図１及び図２により乗物移動装置である搬送装置１０について説明する。図２は図１をＩ−Ｉから見た矢視図である。台車１１の長手方向前後には走行装置１５が設けられ、台車１１上面には旋回装置１２を介して昇降装置１３が取付けられている。昇降装置１３の先端にはアーム１４が取付けられている。アーム１４は、この場合、トレーラ２０の車輪径の約１／２の間隔で２本のアームによって構成され、少なくともトレーラ２０の左右の前輪幅よりも長く構成されている。昇降装置１３は旋回装置１２によって、アーム１４の長手方向の向きを
９０度毎回転可能になっている。この場合、アーム１４の回転方向は一方向に設定してあり、アーム１４が１８０度回転してアーム１４の左右が入れ替わるようにしてある。これにより、アーム１４の片側のみへの偏過重を防止する。
【００１０】
図１は図８における位置Ａ点での様子を示しており、アーム１４の長手方向が搬送装置１０の走行方向に向けられ、昇降装置１３によってアーム１４を最下部まで下げて、搬送装置１０は位置Ａ点に入って来る。位置Ａ点で停止した搬送装置１０は、図３及び図４に示すようにアーム１４を回転移動させる。図４は図３をＩＩ−ＩＩから見た矢視図である。旋回装置１２はアーム１４を、この場合、右回転で９０度回転させ、すなわち、搬送装置１０の走行方向に対して直角方向に回転させて、トレーラ２０の左右両前輪の下方に位置させる。次に、図５及び図６に示すようにアーム１４を上昇させる。図６は図５をＩＩＩ−ＩＩＩから見た矢視図である。昇降装置１３はアーム１４を所定位置まで上昇させる。これにより、アーム１４が左右両前輪に当接し、その後前輪を支持して持上げ、走行フロア４から浮かせる。搬送装置１０は、トレーラ２０の前輪を持上げた状態で、前述のように検査建屋方向にトレーラ２０を移動させる。
【００１１】
また、搬出建屋３の停止位置Ｂ点においては、上述した位置Ａ点での逆動作を行い、図１に示す搬送装置１０の状態で、すなわち、アーム１４の長手方向の向きを搬送装置１０の走行方向に対して平行にした状態で、搬送装置１０が位置Ａ点に戻って来る。
【００１２】
なお、ピット５における位置Ａ点及びＢ点では、搬送装置１０の点検スペースも含めアーム１４が回転可能な幅のスペースが確保され、その他の部分のピット内は、図５をＩＶ−ＩＶから見た矢視図である図７に示すように搬送装置１０が通過可能でアーム１４の長手方向の長さＨ_０よりも狭いピット幅Ｈ_２となっている。これにより、建屋長手方向のピット５を設ける土木工事における負担を軽減させることができる。さらに、ピット幅Ｈ_２をトレーラ２０の車輪中心幅より狭くすることにより、ピット５上部の走行フロア４のカンチレバー構造の強度を小さくでき、さらに土木工事における負担を軽減させることができる。また、ピット５における位置Ａ点及びＢ点のみに、アーム１４がピット５内から走行フロア４上に抜けられる開口が設けてある。
【００１３】
また、搬送装置１０は、搬出建屋３の方向への移動速度よりも搬入建屋２の方向への移動速度を早くしてあり、全体の処理時間を短縮するようにしてある。移動速度の切替は、アーム１４の回転位置又は旋回装置１２の回転位置を検出して、切替信号の１つの信号として用いるのが良い。すなわち、アーム１４の長手方向が搬送装置１０の走行方向に向いている場合に、移動速度を早くする。さらに、搬送装置１０においては、少なくとも検査建屋１の区間はＸ線検査に必要な移動速度で走行移動し、その前後は速度を速めるようにしても良い。
【００１４】
これにより、土木工事の負担を軽減するとともに効率的な移動を可能にすることができる。すなわち、本実施例における他の特徴は、搬入，検査，搬出の建屋内に一連の乗物移動ラインを形成し、乗物移動ラインの中央下側にピットを設け、該ピット内に搬入建屋に持ち込まれた乗物の前輪を浮かせて保持し乗物を搬出建屋まで移動させる搬送装置を設け、移動速度制御手段により少なくとも検査中の乗物の移動速度を所定の速度で移動させ、乗物を保持していないときの搬送装置の移動速度を検査中の移動速度より速い速度で移動させることにある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle inspection equipment and a vehicle moving device, and more particularly to a vehicle inspection equipment and a vehicle moving device for heavy objects such as a trailer or a truck loaded with luggage.
[0002]
[Prior art]
As conventional inspection equipment, pits are provided on both sides in a direction perpendicular to the towing direction of a towing route such as a trailer or a truck, as described in EP 0491977 A1, and a towing device is arranged at each of the pit portions on both sides. There is also known an apparatus which holds a tire such as a trailer or a truck from both sides and moves and drives a towing device to move and transport the trailer or a truck.
[0003]
[Problems to be solved by the invention]
In the above prior art, the pits are installed on both sides, so that the pits become two places and the floor on which a heavy load is placed has a cantilever structure, and it is necessary to have sufficient strength. There is a problem in that the load is increased, and two devices themselves are required due to the arrangement of the towing devices on both sides, and two synchronous operation controls are required, which is complicated.
[0004]
An object of the present invention is to provide a vehicle inspection equipment and a vehicle moving device capable of reducing the burden of civil engineering work on a pit provided with a transfer device for moving an inspection object provided below the inspection line.
[0005]
[Means for Solving the Problems]
The above object is to hold a front wheel of a vehicle from below the vehicle by an arm at the center lower side of a vehicle moving line in a series of loading, inspection, and unloading buildings, raise and lower the arm by a lifting device, and attach a lifting device. The trolley is moved by the traveling device from the loading building to the unloading building along the guide rail below the vehicle movement line, and the entire longitudinal direction of the arm is rotated by the turning device to change the direction, and the direction perpendicular to the traveling direction is changed. This is achieved by using a vehicle moving device having a reduced width dimension and controlled to move from the carry-out building to the carry-in building.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. First, FIG. 8 shows an overview of the inspection equipment. 1 is an inspection building, 2 is a carry-in building, 3 is a carry-out building, and is a series of buildings. A pit 5 is provided at the lower center of the traveling floor 4 of the loading building 2, the inspection building 1, and the unloading building 3, and a guide rail 6 extending from the loading building 2 to the unloading building 3 is laid on the bottom surface of the pit 5. A transport device 10 is arranged on the guide rail 6 and reciprocates on the guide rail 6 in the longitudinal direction. An X-ray irradiator 7 is provided above the inspection building 1, and an X-ray receiver 8 is provided below the pit 5 so as to face the X-ray irradiator 7, thereby forming a vertical X-ray inspection device. A horizontal X-ray inspection device 9 is installed near the vertical X-ray inspection device in the inspection building 1.
[0007]
In this case, the vehicle is a vehicle, the trailer 20 travels on the traveling floor 4 and stops at a predetermined position A in the loading building 2, and the driver now leaves the trailer. After confirming that the driver has left the loading building, the partition between the loading building 2 and the inspection building 1 is opened, and the transport device 10 starts moving toward the inspection building 2 while holding the front wheels of the trailer 20. After confirming that the trailing end of the trailer 20 has entered the inspection building 1 due to the movement of the transport device 10, the partition between the loading building 2 and the inspection building 1 is closed. When the trailer 20 comes to a predetermined position in the inspection building 1, the vertical and horizontal X-ray inspection apparatus starts operating, and the trailer 20 passes at a predetermined speed. When the trailer 20 passes through the X-ray inspection device, the irradiation of X-rays is stopped, the partition between the inspection building 1 and the unloading building 3 is opened, and the transport device 10 moves the trailer 20 to the predetermined stopping position in the unloading building 3. Move to point B. After confirming that the transport device 10 has released the holding of the front wheels of the trailer 20, the driver gets on the trailer 20 and carries the trailer 20 out of the unloading building.
[0008]
In addition, if the trailer 20 moves from the loading building 2 and the trailer 20 disappears in the loading building 2, a new trailer can be brought in and the inspection process is sequentially performed.
[0009]
Next, a transport device 10 which is a vehicle moving device will be described with reference to FIGS. FIG. 2 is an arrow view of FIG. 1 as viewed from II. A traveling device 15 is provided before and after the bogie 11 in the longitudinal direction, and an elevating device 13 is mounted on a top surface of the bogie 11 via a turning device 12. An arm 14 is attached to a tip of the lifting device 13. In this case, the arm 14 is constituted by two arms at an interval of about の of the wheel diameter of the trailer 20, and is longer than at least the left and right front wheel widths of the trailer 20. The elevating device 13 can rotate the direction of the arm 14 in the longitudinal direction by 90 degrees by the turning device 12. In this case, the rotation direction of the arm 14 is set to one direction, and the arm 14 rotates 180 degrees so that the left and right of the arm 14 are switched. This prevents the overload of the arm 14 on only one side.
[0010]
FIG. 1 shows a state at a position A in FIG. 8, in which the longitudinal direction of the arm 14 is directed to the traveling direction of the transfer device 10, the arm 14 is lowered to the lowermost position by the elevating device 13, and the transfer device 10 You come into position A. The transport device 10 stopped at the position A rotates the arm 14 as shown in FIGS. FIG. 4 is an arrow view of FIG. 3 as viewed from II-II. In this case, the turning device 12 rotates the arm 14 by 90 degrees clockwise, that is, by rotating the arm 14 in a direction perpendicular to the traveling direction of the transport device 10 to position the arm 14 below the left and right front wheels of the trailer 20. Next, the arm 14 is raised as shown in FIGS. FIG. 6 is an arrow view of FIG. 5 viewed from III-III. The lifting device 13 raises the arm 14 to a predetermined position. As a result, the arm 14 comes into contact with both the left and right front wheels, and then supports and lifts the front wheel, and lifts it off the traveling floor 4. The transport device 10 moves the trailer 20 in the inspection building direction as described above with the front wheel of the trailer 20 lifted.
[0011]
In addition, at the stop position B of the unloading building 3, the reverse operation at the position A described above is performed, and in the state of the transfer device 10 shown in FIG. The transport device 10 returns to the position A in a state where the transport device 10 is parallel to the traveling direction.
[0012]
At positions A and B in the pit 5, a space is secured for the arm 14 to be rotatable, including a space for inspection of the transfer device 10, and the other pits are shown in FIG. conveying device 10 as shown in FIG. 7 has a narrow pit width H ₂ than the longitudinal length H ₀ of the arm 14 can pass through the an arrow view. Thereby, the burden on the civil engineering work for providing the pits 5 in the longitudinal direction of the building can be reduced. Furthermore, by narrowing the pit width H ₂ from wheel center width of the trailer 20, the strength of the cantilever structure of the pit 5 the upper part of the traveling floor 4 can be reduced, it is possible to further reduce the burden in civil engineering. Further, only at the points A and B in the pit 5, there are provided openings through which the arm 14 can pass out of the pit 5 and onto the traveling floor 4.
[0013]
Further, the transfer speed of the transfer device 10 in the direction of the carry-in building 2 is higher than that in the direction of the carry-out building 3, thereby shortening the overall processing time. The switching of the moving speed is preferably performed by detecting the rotational position of the arm 14 or the rotational position of the turning device 12 and using the detected rotational position as one of the switching signals. That is, when the longitudinal direction of the arm 14 is oriented in the traveling direction of the transfer device 10, the moving speed is increased. Further, in the transport device 10, at least the section of the inspection building 1 may travel at a moving speed necessary for the X-ray inspection, and the speed may be increased before and after that.
[0014]
As a result, the burden of civil works can be reduced and efficient movement can be achieved. That is, another feature of the present embodiment is that a series of vehicle moving lines are formed in the building for carrying in, inspecting, and carrying out, a pit is provided below the center of the vehicle moving line, and the pit is taken into the loading building. A transport device is provided for lifting and holding the front wheels of the vehicle and moving the vehicle to the unloading building, and moving speed of the vehicle under inspection at least at a predetermined speed by the moving speed control means, when the vehicle is not held. It is an object of the present invention to move the transfer device at a speed higher than the test speed during the inspection.
