〔産業上の利用分野〕
本発明は主として、荷台式の貨物トラックに装備される
荷役装置の姿勢調整機構に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to an attitude adjustment mechanism for a cargo handling device installed in a bed type cargo truck.
荷台タイプの貨物トラックに於て、クレーン式の荷役装
置を装備したものは公知である。また、荷台の後側板が
水平な姿勢で昇降をするように構成されたリフト式の荷
役装置を具備したものも公知である。BACKGROUND OF THE INVENTION Among platform-type cargo trucks, those equipped with a crane-type cargo handling device are known. Further, there is also known a lift-type cargo handling device configured such that the rear side plate of the cargo platform moves up and down in a horizontal position.
しかし、上記従来の荷役装置には様々な難点があること
に鑑み、本発明の発明者は先に貨物トラックに装備して
有用な荷役装置を実願昭６３−１０６０３０号として提
案した。However, in view of the various drawbacks of the above-mentioned conventional cargo handling devices, the inventor of the present invention previously proposed a useful cargo handling device that can be installed on cargo trucks as U.S. Pat. No. 63-106030.
先に提案した装置は、貨物トラックにおける運転席キャ

材の下端に荷物の支持部を形戊したものである。The previously proposed device has a first arm member, which has a length that fits approximately within the front width of the cabin, on the upper part of the external rear side of the driver's cabin in a cargo truck, and has a vertical axis at the rear end of the arm member. At the same time, a second arm member is rotatably connected to the tip of the first arm member, a hoisting mechanism is attached to the tip of the second arm member, and the hoist is rolled up from there.
A rope member is suspended by a belt or the like that is wound down, and a cargo support portion is formed at the lower end of the rope member.

更に、上記荷役装置の巻上機構を第二腕部材の後端側に

２１号として提案している。In addition, the inventor of the present invention proposed a mounting frame for this cargo handling device in which support members such as poles are erected on the bed of a cargo truck as U.S. Pat. No. 63-168767,
Furthermore, a cargo handling device for a cargo truck in which the hoisting mechanism of the cargo handling device is disposed on the rear end side of the second arm member is disclosed in Utility Model Application No. 1-70.
It is proposed as No. 21.
これらの荷役装置は、その主要構或メンバーである腕部

てそのキャビンと平行に収納されるので、邪魔になるこ
とがないという特徴がある。These cargo handling devices are shaped so that the arm member, which is the main structural member, is attached to the outside of the rear surface of the driver's cabin so that the rear end of the arm member can pivot around a vertical axis. It has the inherent advantage that even if this cargo handling device is installed, it will hardly narrow the loading bed of the truck.In addition, when not in use, the arm member is attached to the upper rear of the driver's cabin. It has the characteristic that it is stored parallel to the cabin within its width, so it does not get in the way.
特に、実願平１− ７０２１号として提案した荷役装置

う特有の効果がある。In particular, the cargo handling device proposed in Utility Model Application No. 1-7021 has good load balance on the left and right sides of the cargo truck bed. In addition, since a tilt sensor is provided, it is possible to detect that the first arm member is tilted with respect to the left or right of the loading platform of the vertical shaft (mounting shaft) attached to the upper end of the support member at the rear end of the first arm member. At the same time, based on the tilt signal from this tilt sensor, the swinging mechanism installed in the strut mounting base that erects the strut member on the loading platform can be operated to tilt the strut member left and right. , The unique effect is that the mounting axis can be prevented from tilting even if it is tilted to the right, and it is possible to prevent the arm drifting phenomenon in which the arm member of the cargo handling device moves to the left or right due to the left or right tilt of the loading platform. There is.
しかしながら、この荷役装置にも更に、解決すべき課題
がある。However, this cargo handling device also has problems to be solved.
即ち、実願平１− ７０２１号として提案した荷役装置

ム流れ現象を回避できない。In other words, the cargo handling device proposed in Utility Application No. 1-7021 only corrects the inclination of the mounting shaft when the loading platform of a cargo truck tilts to the left or right; Since there is no structure for correcting the inclination of the cargo platform, it is impossible to avoid the arm drift phenomenon in which the arm member on which the cargo is suspended moves in the front and rear directions of the cargo platform if the cargo platform is inclined in the front-rear direction.

載する作業の過程や，坂道等に停止して荷積卸し作業時
には、荷台が除々に前，後に傾斜したり、当初から傾斜
しているため、アームが荷台の前後に関して流れること
が生じる。In particular, during the process of unloading cargo one by one, loading cargo one after another, or stopping on a slope etc. for loading and unloading work, the loading platform may gradually tilt forward or backward, or may tilt from the beginning. As a result, the arm may flow in relation to the front and rear of the loading platform.

作を行うことは煩わしい面があった。In addition, even though it is possible to correct the inclination of the mounting shaft based on the signal from the inclination sensor when the loading platform is tilted to the left or right, it is difficult to correct the inclination during loading or unloading operations. It was a hassle to do so.

とができる。In FIG. 13, 9c' is a telescoping arm member, 3' is a telescoping column, and other symbols are the same as in the embodiment shown in FIG. [Effects of the Invention] As described above, the attitude adjustment mechanism of the present invention detects, using a verticality sensor, the inclination with respect to the verticality of the pivot shaft on which the cargo handling device is attached, which has an arm that can freely pivot within a plane. Based on the tilt signal, the mounting member on which the pivot shaft is erected is corrected horizontally by controlling the drive of the rotation or stroke actuator such as a motor or motor cylinder. Since the swing of the arm member of the cargo truck can always be maintained horizontally even if the loading platform of the cargo truck is tilted back and forth or left and right, it is possible to prevent so-called arm flow development in all directions within the horizontal plane.
