Description

本発明は、照明装置を備えるとともに、車両上面に梯子や折畳式ボート等の長尺物を積載することが可能な照明付昇降装置に関するものである。   The present invention relates to an illumination lifting apparatus that includes an illumination device and can load a long object such as a ladder or a folding boat on an upper surface of a vehicle.

例えば、消防用車両等の車体上面には、デッドスペースの有効活用のため梯子や折畳式ボート等の長尺物を積載し、それらを必要に応じて救助活動等に用いることが行われている。しかしながら、車体上面への長尺物の上げ降ろしは、人間がその都度車体上面にまで登って、上と下とで長尺物の受け渡しをする必要があり、迅速な上げ下ろしが難しく、また危険を伴うものでもあった。   For example, long objects such as ladders and folding boats are loaded on the upper body of fire fighting vehicles, etc. for effective use of dead space and used for rescue activities as necessary. Yes. However, it is difficult for humans to climb up and down the upper surface of the vehicle body every time the human body climbs up to the upper surface of the vehicle body, and to transfer the upper and lower objects. But it was.

この問題点に対し本願発明者らは下記[特許文献1]に記載の昇降装置及び昇降装置付車両を発明した。この図8に示す[特許文献1]に記載の昇降装置2は、車両1の上面1Aに長尺物を搭載する荷台3を有し、この荷台3を駆動軸7を支点に回動するスイングアーム9と、荷台3をスライド可能に支持する支持体5とで保持している。そして、積載状態において荷台3は、図8中の実線に示すように車両1の上面1Aに沿って略水平の状態に保持される。また、長尺物の昇降時にはスイングアーム9が回動して、荷台3が図8中の一点鎖線で示すように車両1の上面1Aから支持体5を支点として傾きながら車両1の後方に降下する。よって、この[特許文献1]に記載の発明によれば、長尺物を簡単かつ迅速に昇降することができる。   In order to solve this problem, the inventors of the present invention invented a lifting device and a vehicle with a lifting device described in [Patent Document 1] below. The lifting device 2 described in [Patent Document 1] shown in FIG. 8 has a loading platform 3 on which a long object is mounted on the upper surface 1A of the vehicle 1, and a swing that rotates the loading platform 3 with a drive shaft 7 as a fulcrum. The arm 9 and the support body 5 that slidably supports the loading platform 3 are held. In the loaded state, the loading platform 3 is held in a substantially horizontal state along the upper surface 1A of the vehicle 1 as shown by a solid line in FIG. Further, the swing arm 9 is rotated when the long object is raised and lowered, and the loading platform 3 descends from the upper surface 1A of the vehicle 1 to the rear of the vehicle 1 while tilting from the upper surface 1A of the vehicle 1 with the support body 5 as a fulcrum as shown by a dashed line in FIG. To do. Therefore, according to the invention described in [Patent Document 1], a long object can be lifted and lowered easily and quickly.

ところで、例えば夜間や暗所での作業では、作業場所を照らす照明灯が必要不可欠である。この際の照明は高所から照らすことが好ましい。ここで、下記[特許文献2]には昇降自在なアンテナ型照明体を備えた消防車に関する考案が開示されている。   By the way, for example, at night or in a dark place, an illumination lamp that illuminates the work place is indispensable. It is preferable to illuminate from a high place. Here, the following [Patent Document 2] discloses a device relating to a fire engine equipped with an antenna-type illuminator that can be moved up and down.

特許第4217193号公報Japanese Patent No. 4217193 実開昭63−79951号公報Japanese Utility Model Publication No. 63-79951

しかしながら[特許文献2]のように高所照明の用途のためにアンテナ型照明体を設置することは費用の面からも省スペースの面からも好ましいものではない。また、クレーン装備車やはしご車には照明灯を備えたものも存在するが、高所照明のためにクレーン装備車やはしご車を常時出動させるのは現実的ではない。   However, as in [Patent Document 2], it is not preferable from the viewpoint of cost and space saving to install an antenna-type illuminating body for the purpose of lighting in high places. In addition, some crane-equipped vehicles and ladder vehicles are equipped with illumination lights. However, it is not practical to always use a crane-equipped vehicle or a ladder vehicle for lighting at high places.

本発明は上記事情に鑑みてなされたものであり、長尺物を積載する昇降装置の先側に照明灯を備え、高所からの照明灯としても利用可能な照明付昇降装置を提供することを目的とする。   The present invention has been made in view of the above circumstances, and provides an illumination lifting apparatus that includes an illumination lamp on the front side of an elevation apparatus that loads a long object and can be used as an illumination lamp from a high place.

Moreover, although the elongate thing W here mainly assumes the ladder and the folding boat, it is not limited to this in particular.

照明付昇降装置80の荷台3はアングルプレートなどから成る長方形の枠体であり、その後端には接地用脚12を有している。ここで、荷台3の好ましい一例の段面図を図3(a)、(b)に示す。図3(a)、(b)に示す荷台3は、左右の側枠部材11に2つのアングルプレートを結合したものを用い、底面側に形成される幅狭な第1収納部13(13A、13B)と、上面側に形成される幅広な第2収納部14とを持つ二段構造としている。また、左右の側枠部材11は横リブ15により連結され、その横リブ15に直交して固定される縦リブ16にはL字形の仕切部材17がヒンジ18を介して設置されている。そして、仕切部材17は図3(a)に示す直立状態と、図3(b)に示す倒伏状態とに切換が可能である。この仕切部材17の構成によれば、第1収納部13は仕切部材17により左右2つの領域13A、13Bに区分され、仕切部材17の直立時には図3(a)に示すように、第2収納部14に折畳式ボート等の幅広の長尺物W1を積載可能としている。また、仕切部材17の倒伏時には図3(b)に示すように、第1収納部13の左右の領域13A、13Bに伸縮式の救助梯子等の長尺物W2、W3を2つ積載可能としている。尚、上記の例は荷台3の好ましい一例であるから、特にこの構成に限定されるものではなく、仕切部材17を設けずに単純に第1収納部13と第2収納部14の2段構造、もしくは収容部が1段の構造としても良い。   The loading platform 3 of the illuminated lifting device 80 is a rectangular frame made of an angle plate or the like, and has a grounding leg 12 at the rear end. Here, a step view of a preferable example of the loading platform 3 is shown in FIGS. The loading platform 3 shown in FIGS. 3A and 3B uses a combination of two angle plates to the left and right side frame members 11, and a narrow first storage portion 13 (13A, 13A, 13B) and a wide second storage portion 14 formed on the upper surface side. The left and right side frame members 11 are connected by horizontal ribs 15, and L-shaped partition members 17 are installed via hinges 18 on the vertical ribs 16 fixed orthogonally to the horizontal ribs 15. The partition member 17 can be switched between an upright state shown in FIG. 3A and a lying state shown in FIG. According to the configuration of the partition member 17, the first storage portion 13 is divided into two left and right regions 13 </ b> A and 13 </ b> B by the partition member 17, and when the partition member 17 stands upright, as shown in FIG.

Here, FIG. 5 is a plan view showing a schematic configuration of the illumination lifting apparatus 80 according to the present invention. As shown in FIG. 5, the lifting mechanism of the lighting lift 80 according to the present invention has a drive unit 6 installed on the vehicle upper surface 1 </ b> A, and this drive unit 6 uses a battery of the lift-equipped vehicle 100 as a power source. Drive means such as a known electric motor, a known speed reducer that reduces the rotational force of the drive means and improves the torque, and a drive that is connected to the speed reducer and extends in the vehicle width direction of the vehicle 100 with the lifting device And a shaft 7. In addition, an operation box (not shown) for operating the drive unit 6 is installed in the vehicle 100 with the lifting device, and the drive shaft 7 of the drive unit 6 is operated by operating a lift switch installed in the operation box. Rotates in the forward and reverse directions.

また、駆動軸7には左右のスイングアーム9の一端がそれぞれ固定されている。よって、スイングアーム9は駆動軸7の回転に伴って、駆動軸7を支点に回動する。また、スイングアーム9の他端は、図1、図2に示すように、荷台連結軸62を介して荷台3に接続される。尚、左右のスイングアーム9は駆動軸7と平行な横架バー41によって連結し、駆動軸7に過大な捩りモーメントが作用しないようにすることが好ましい。また、駆動軸7にはその回転力を調整するための調速機10を取り付け、駆動部6にかかる負荷を軽減しながらスイングアーム9を安定した速度で回動させることが好ましい。尚、スイングアーム9の長さは荷台3の半分程度とすることが好ましい。また、スイングアーム9と接地用脚12とには図示せぬセンサ(例えば、接触型のリミットスイッチ)が設けられ、スイングアーム9の原点位置及び終点位置を検知して駆動部6の停止動作を行う。ここで、スイングアーム9の原点位置とは、図1に示す荷台3が車両上面1A上で略水平に支持された積載状態での位置であり、終点位置とは図2に示す荷台3の降下が完了した降下状態での位置である。   In addition, one end of each of the left and right swing arms 9 is fixed to the drive shaft 7. Therefore, the swing arm 9 rotates with the drive shaft 7 as a fulcrum as the drive shaft 7 rotates. Moreover, the other end of the swing arm 9 is connected to the loading platform 3 via a loading platform coupling shaft 62 as shown in FIGS. The left and right swing arms 9 are preferably connected by a horizontal bar 41 parallel to the drive shaft 7 so that an excessive torsional moment does not act on the drive shaft 7. Further, it is preferable to attach a speed governor 10 for adjusting the rotational force to the drive shaft 7 and to rotate the swing arm 9 at a stable speed while reducing the load applied to the drive unit 6. The length of the swing arm 9 is preferably about half that of the loading platform 3. The swing arm 9 and the grounding leg 12 are provided with a sensor (not shown) (for example, a contact type limit switch), which detects the origin position and the end position of the swing arm 9 to stop the driving unit 6. Do. Here, the origin position of the swing arm 9 is a position when the loading platform 3 shown in FIG. 1 is supported substantially horizontally on the vehicle upper surface 1A, and the end position is the lowering of the loading platform 3 shown in FIG. Is the position in the lowered state.

また、スイングアーム9の先側にはシャフトプレート63が設置され、このシャフトプレート63にはスイングアーム9と照明灯50の台座部52とを繋ぐ連結シャフト66の一端が回転可能に接続される。尚、本例では連結シャフト66の一端に第1シャフト軸64aを設け、この第1シャフト軸64aをシャフトプレート63の軸孔に回転可能に嵌入することでスイングアーム9と連結シャフト66とを接続している。尚、連結シャフト66の一端の接続位置、即ち本例における第1シャフト軸64aの位置は、後述の図7に示すように、スイングアーム9の長辺方向から回動側(終点側)に向かって角度θ1をなしている。   A shaft plate 63 is installed on the front side of the swing arm 9, and one end of a connecting shaft 66 that connects the swing arm 9 and the pedestal portion 52 of the illumination lamp 50 is rotatably connected to the shaft plate 63. In this example, a first shaft shaft 64 a is provided at one end of the connecting shaft 66, and the swing arm 9 and the connecting shaft 66 are connected by rotatably inserting the first shaft shaft 64 a into the shaft hole of the shaft plate 63. doing. Note that the connection position of one end of the connecting shaft 66, that is, the position of the first shaft shaft 64a in this example is from the long side direction of the swing arm 9 toward the rotation side (end point side) as shown in FIG. Angle θ1.

Here, FIG. 6 is an enlarged perspective view of the illuminating lamp portion of the lighting lift 80 according to the present invention. Moreover, FIG. 7 is a figure explaining the installation structure of an illumination lamp.

先ず、照明灯50はLEDやキセノンランプ、ハロゲンランプ等の周知の照明装置であり、昇降装置付車両100に搭載されたバッテリを電源として発光する。また、照明灯50は雲台部54a、54bを介して台座部52に設置される。ここで、雲台部54aは例えばコの字状のホルダにて照明灯50を回動可能に挟持し、照明灯50の照射角度を変化させるものである。また、雲台部54bは照明灯50を雲台部54aごと360°回転可能とし、照明灯50の照射方向を変化させるものである。尚、照明灯50のオン・オフ、及び雲台部54a、54bの操作は無線及び有線の照明コントローラを用いて行うことができる。例えば、照明灯50を使用する際には、照明コントローラの点灯ボタンを押下することで照明灯50が点灯する。また、照明コントローラの角度調整ボタンを押下することで雲台部54aに内蔵されたモータが駆動し、照明灯50の照射角度が上下方向に変化する。また、照明コントローラの回転ボタンを押下することで雲台部54bに内蔵されたモータが駆動して照明灯50が回転し、照明灯50の照射方向が変化する。この照明灯50の動作は、後述の荷台3の昇降動作とは別に独立して行うことができる。   First, the illuminating lamp 50 is a well-known illuminating device such as an LED, a xenon lamp, or a halogen lamp, and emits light using a battery mounted on the vehicle 100 with a lifting device as a power source. The illuminating lamp 50 is installed on the pedestal 52 through the pan heads 54a and 54b. Here, the pan head part 54a is configured to change the irradiation angle of the illumination lamp 50 by holding the illumination lamp 50 rotatably with a U-shaped holder, for example. In addition, the pan head part 54b allows the illuminating lamp 50 to rotate 360 ° together with the pan head part 54a to change the irradiation direction of the illuminating lamp 50. The illumination lamp 50 can be turned on / off and the pan head portions 54a and 54b can be operated using wireless and wired illumination controllers. For example, when the illuminating lamp 50 is used, the illuminating lamp 50 is turned on by pressing a lighting button of the illumination controller. Further, when the angle adjustment button of the illumination controller is pressed, the motor built in the camera platform 54a is driven, and the irradiation angle of the illumination lamp 50 changes in the vertical direction. Further, when the rotation button of the illumination controller is pressed, the motor built in the camera platform 54b is driven to rotate the illumination lamp 50, and the irradiation direction of the illumination lamp 50 is changed. The operation of the illuminating lamp 50 can be performed independently of the lifting / lowering operation of the loading platform 3 described later.

また、照明灯50(雲台部54b)が設置される台座部52は、図7に示すように、角度θ2で上方に屈曲した台座アーム部52aを有しており、この台座部52の屈曲部には連結シャフト66の他端が回転可能に接続する。尚、本例では台座部52の屈曲部に第2シャフト軸64bを設け、この第2シャフト軸64bに連結シャフト66の他端を回転可能に嵌入することで台座部52と連結シャフト66とを接続している。そして、台座アーム部52aの先側には荷台3の先側に設置されたアーム回転軸60が回転可能に嵌入し、これにより台座部52は荷台3の先側と連結する。尚このとき、雲台部54bのXY面が略水平となるよう各部の寸法を設計する。また、台座部52と荷台3との間には、図6に示すように、荷台3から台座部52に伝達する衝撃等を緩和するダンパ部材68を設けても良い。   Further, as shown in FIG. 7, the pedestal portion 52 where the illuminating lamp 50 (the pan head portion 54 b) is installed has a pedestal arm portion 52 a bent upward at an angle θ 2, and the pedestal portion 52 is bent. The other end of the connecting shaft 66 is rotatably connected to the part. In this example, the second shaft shaft 64b is provided at the bent portion of the pedestal portion 52, and the other end of the connecting shaft 66 is rotatably fitted into the second shaft shaft 64b so that the pedestal portion 52 and the connecting shaft 66 are connected. Connected. And the arm rotating shaft 60 installed in the front side of the loading platform 3 is rotatably inserted in the front side of the base arm part 52a, and, thereby, the base part 52 connects with the front side of the loading base 3. At this time, the dimensions of each part are designed so that the XY plane of the pan head part 54b is substantially horizontal. Further, as shown in FIG. 6, a damper member 68 may be provided between the pedestal portion 52 and the loading platform 3 to relieve an impact transmitted from the loading platform 3 to the pedestal portion 52.

そして、図7に示すように、台座部52の屈曲部の角度θ2と前述の角度θ1とは略同等の値とする。また、スイングアーム9の荷台連結軸62から連結シャフト66の一端の接続位置(第1シャフト軸64aの位置)までの長さをL1とし、台座部52における連結シャフト66の接続位置(第2シャフト軸64bの位置)からアーム回転軸60までの長さをL2としたときに、長さL1と長さL2とは略同等の値とする。   Then, as shown in FIG. 7, the angle θ2 of the bent portion of the pedestal portion 52 and the aforementioned angle θ1 are set to substantially the same value. Further, the length from the loading platform connecting shaft 62 of the swing arm 9 to the connecting position of one end of the connecting shaft 66 (the position of the first shaft shaft 64a) is L1, and the connecting position of the connecting shaft 66 in the pedestal portion 52 (the second shaft). When the length from the position of the shaft 64b) to the arm rotation shaft 60 is L2, the length L1 and the length L2 are substantially equal values.

次に、本発明に係る照明付昇降装置80の昇降動作を説明する。先ず、照明付昇降装置80上に積載された長尺物Wを降ろす場合、昇降装置付車両100に設置された図示せぬ昇降スイッチを操作して駆動部6を正方向(図面中時計回り方向)に回転させる。これにより、駆動軸7が正方向に回転し、スイングアーム9が駆動軸7を支点として正方向に回動する。これにより、荷台3との連結部である荷台連結軸62は駆動軸7を中心としスイングアーム9を半径とした円軌道に沿って移動する。このとき、荷台3の後部側は支持体5でスライド可能に保持されているため、荷台3はスイングアーム9の回動に伴い支持体5を支点にして徐々に傾斜する。またこれと同時に荷台3の後部側は支持体5をスライドして昇降装置付車両100の後端から徐々に迫り出す。そして、スイングアーム9が終点位置近傍に達すると、接地用脚12が着地するとともに図示せぬセンサ等がこれを検知して駆動部6が停止し、図2に示す降下状態となる。そして、この降下状態において、長尺物Wを固定しているチェーンやベルト等を解除し長尺物Wを取り外して目的の用途に使用する。   Next, the raising / lowering operation | movement of the raising / lowering apparatus 80 with illumination which concerns on this invention is demonstrated. First, when unloading the long object W loaded on the illuminated lifting device 80, the drive unit 6 is moved in the forward direction (clockwise direction in the drawing) by operating a lifting switch (not shown) installed in the vehicle 100 with the lifting device. ) To rotate. As a result, the drive shaft 7 rotates in the forward direction, and the swing arm 9 rotates in the forward direction with the drive shaft 7 as a fulcrum. As a result, the loading platform connecting shaft 62, which is a connecting portion with the loading platform 3, moves along a circular path centering on the drive shaft 7 and having the swing arm 9 as a radius. At this time, since the rear side of the loading platform 3 is slidably held by the support body 5, the loading platform 3 is gradually inclined with the support body 5 as a fulcrum as the swing arm 9 rotates. At the same time, the rear side of the cargo bed 3 slides the support 5 and gradually approaches the rear end of the vehicle 100 with the lifting device. When the swing arm 9 reaches the vicinity of the end point position, the grounding leg 12 is landed, and a sensor or the like (not shown) detects this, and the drive unit 6 stops, and the lowered state shown in FIG. In this lowered state, the chain or belt that fixes the long object W is released, and the long object W is removed to be used for the intended use.

使用後の長尺物Wを昇降装置付車両100上へ積載する場合には、先ず、降下状態の荷台3の所定の位置に長尺物Wを配置し、チェーンやベルト等で固定する。次に、昇降スイッチを操作して駆動部6を逆方向に回転させる。これにより、スイングアーム9は逆方向(図面中反時計回り方向)に回動し、荷台3は車両上面1A方向に徐々に倒伏する。そして、スイングアーム9が原点位置に達すると、図示せぬセンサ等がこれを検知して駆動部6が停止し、図1に示す長尺物Wの積載状態となる。   When loading the long object W after use onto the vehicle 100 with the lifting device, first, the long object W is disposed at a predetermined position of the loading platform 3 in the lowered state, and fixed with a chain, a belt, or the like. Next, the elevating switch is operated to rotate the drive unit 6 in the reverse direction. As a result, the swing arm 9 rotates in the reverse direction (counterclockwise direction in the drawing), and the loading platform 3 gradually falls in the direction of the vehicle upper surface 1A. When the swing arm 9 reaches the origin position, a sensor or the like (not shown) detects this, and the drive unit 6 stops, and the long object W shown in FIG.

この昇降動作時のスイングアーム9の回動動作に伴い、スイングアーム9と連結シャフト66を介して繋がった台座部52もアーム回転軸60を支点に回動する。このとき、前述のようにスイングアーム9側のなす角θ1と台座部52側のなす角θ2とは略同等の値であり、スイングアーム9側の長さL1と台座部52側の長さL2とは略同等の値であるから、連結シャフト66の一端(第1シャフト軸64a)の荷台連結軸62に対する変位量と、連結シャフト66の他端(第2シャフト軸64b)のアーム回転軸60に対する変位量とは略同等となる。そして、荷台連結軸62とアーム回転軸60との位置関係は連結シャフト66を挟んで両側に位置するから、連結シャフト66の一端(第1シャフト軸64a)の荷台連結軸62を軸とした回動方向と、連結シャフト66の他端(第2シャフト軸64b)のアーム回転軸60を軸とした回動方向とは逆方向となる。これにより、台座部52は荷台3の角度によらず昇降装置付車両100の車両上面1Aに対して略一定の角度を維持する。これにより、雲台部54a、54b及び照明灯50のX、Y、Z軸は常に略一定の方向に保たれる。   As the swing arm 9 is pivoted during the ascending / descending operation, the pedestal 52 connected to the swing arm 9 via the connecting shaft 66 also pivots around the arm rotation shaft 60. At this time, as described above, the angle θ1 formed on the swing arm 9 side and the angle θ2 formed on the pedestal portion 52 side are substantially equal values, and the length L1 on the swing arm 9 side and the length L2 on the pedestal portion 52 side are the same. Are substantially equivalent values, so that the displacement amount of one end (first shaft axis 64a) of the connection shaft 66 with respect to the load carrier connection axis 62 and the arm rotation axis 60 of the other end (second shaft axis 64b) of the connection shaft 66 are. The displacement amount with respect to is substantially the same. Since the positional relationship between the loading platform connecting shaft 62 and the arm rotation shaft 60 is located on both sides of the connecting shaft 66, the rotation of the connecting shaft 66 at one end (the first shaft shaft 64a) with the loading platform coupling shaft 62 as an axis. The direction of movement is opposite to the direction of rotation about the arm rotation shaft 60 at the other end (second shaft shaft 64b) of the connecting shaft 66. Accordingly, the pedestal 52 maintains a substantially constant angle with respect to the vehicle upper surface 1A of the vehicle 100 with a lifting device regardless of the angle of the loading platform 3. As a result, the X, Y, and Z axes of the pan head portions 54a and 54b and the illuminating lamp 50 are always maintained in a substantially constant direction.

ここで仮に、台座部52が上記構成を備えていない場合、台座部52の角度は荷台3の傾斜角度によって変化し、照明灯50の雲台部54a、54bのX、Y、Z軸も荷台3の傾斜角度によって変化する。よって、荷台3の昇降動作中や、照明灯50のXY面が水平でない位置では、照射方向の調整を直感的な上下左右操作で行うことができない。このため、目的の方向に迅速な照明灯50の照射を行うことができない。また、荷台3の傾斜角度によっては雲台部54a、54bの有効動作範囲が制限され、目的の方向を照らすことができない可能性が有る。   Here, if the pedestal portion 52 does not have the above-described configuration, the angle of the pedestal portion 52 varies depending on the inclination angle of the loading platform 3, and the X, Y, and Z axes of the platform portions 54 a and 54 b of the illuminating lamp 50 are loaded. It changes with the inclination angle of 3. Accordingly, the irradiation direction cannot be adjusted by an intuitive up / down / left / right operation during the lifting / lowering operation of the loading platform 3 or at a position where the XY plane of the illumination lamp 50 is not horizontal. For this reason, the illumination lamp 50 cannot be quickly irradiated in the target direction. In addition, depending on the inclination angle of the cargo bed 3, the effective operation range of the pan head portions 54a and 54b is limited, and there is a possibility that the target direction cannot be illuminated.

この点、本発明に係る照明付昇降装置80は、荷台3の傾斜角度によらず照明灯50のX、Y、Z軸が常に略一定の方向(通常はXY面が略水平方向)に保たれる。このため、荷台3がどのような角度にあっても照射方向の調整を直感的な上下左右操作で容易に行うことができる。また、荷台3が昇降動作中であっても照射方向の調整を直感的な上下左右操作で容易に行うことができる。これにより、照明灯50の目標方向への照射を極めて迅速に行うことができる。また、台座部52の角度が略一定に保たれるため、照明灯50の照射方向の調整を雲台部54a、54bの動作範囲内で制限無く行うことができる。   In this respect, the illuminated lifting device 80 according to the present invention maintains the X, Y, and Z axes of the illuminating lamp 50 in a substantially constant direction (normally, the XY plane is generally horizontal) regardless of the inclination angle of the loading platform 3. Be drunk. For this reason, it is possible to easily adjust the irradiation direction by an intuitive up / down / left / right operation regardless of the angle of the loading platform 3. Further, even when the loading platform 3 is moving up and down, the adjustment of the irradiation direction can be easily performed by an intuitive up / down / left / right operation. Thereby, irradiation to the target direction of the illuminating lamp 50 can be performed very rapidly. Further, since the angle of the pedestal 52 is kept substantially constant, the irradiation direction of the illuminating lamp 50 can be adjusted without limitation within the operating range of the camera platform 54a, 54b.

以上のように、本発明に係る照明付昇降装置80は、長尺物Wを積載する荷台3の先側に照明灯50を備えている。そして、荷台3を降下状態とすることで照明灯50を高所に位置させ、高所からの効果的な照明を行うことができる。即ち、本発明に係る照明付昇降装置80は長尺物Wの昇降機能と高所照明機能を兼ね備えるものである。よって、本発明に係る照明付昇降装置80によれば、簡単、低コスト、省スペースで車両本体に高所照明灯を設置することができる。   As described above, the illumination lifting apparatus 80 according to the present invention includes the illumination lamp 50 on the front side of the loading platform 3 on which the long object W is loaded. And the illuminating lamp 50 can be located in a high place by making the loading platform 3 into a lowered state, and effective illumination from a high place can be performed. That is, the lighting lifting device 80 according to the present invention has both a lifting function for the long object W and a lighting function for high places. Therefore, according to the illumination lifting device 80 according to the present invention, it is possible to install the high place illumination lamp on the vehicle main body in a simple, low-cost and space-saving manner.

また、本発明の照明灯50の台座部52は、荷台3の角度によらず略一定の角度を維持する。これにより、荷台3がどのような角度にあっても、また昇降動作中であっても照射方向の調整を直感的な上下左右操作で容易に行うことができる。また、照明灯50の照射方向の調整を雲台部54a、54bの動作範囲内で制限無く行うことができる。これにより、照明灯50の目標方向への照射を極めて迅速に行うことができる。   Further, the pedestal portion 52 of the illuminating lamp 50 of the present invention maintains a substantially constant angle regardless of the angle of the loading platform 3. Thereby, it is possible to easily adjust the irradiation direction by an intuitive up / down / left / right operation regardless of the angle of the loading platform 3 or during the raising / lowering operation. Moreover, the irradiation direction of the illumination lamp 50 can be adjusted without limitation within the operating range of the camera platform parts 54a and 54b. Thereby, irradiation to the target direction of the illuminating lamp 50 can be performed very rapidly.

尚、本例で示した照明付昇降装置80の各部の形状、動作機構、寸法等は一例であり、本発明は本発明の要旨を逸脱しない範囲で変更して実施することが可能である。   It should be noted that the shape, operation mechanism, dimensions, and the like of each part of the illuminated lifting device 80 shown in this example are merely examples, and the present invention can be modified and implemented without departing from the scope of the present invention.
