、プラットホーム用積込み橋に関する。DETAILED DESCRIPTION OF THE INVENTION In order to facilitate the upward pivoting of the bridge plate, a spring-loaded lever acts on the bridge plate from below, in particular via a cam plate. The lower end of the lever is supported on the platform, and a tension spring is provided, one end of which acts on the lever, the tension spring extending rearward from a fixed point on the lever to a region of a pivot point on the bridge plate. Regarding platform loading bridges.

バーによって補償される。Particularly in the case of manually operated loading bridges, the bridge plate must be swiveled upwards and this plate, which is not supported at its free end, must be swiveled downwards without any problems. , the dead weight of the pivotable bridge section is compensated by a spring-loaded lever.
公知のこの種の橋の場合、引張りばねは真直なレバーか
ら橋板の後方区間または橋板の下にあるプラットホーム
構造体の固定点まで延びている。In known bridges of this type, the tension springs extend from a straight lever to a fixed point in the platform structure located in the rear section of the deck or under the deck.
この構造はばねを最適に利用することができ ゛ないと
いう欠点がある。ばねの自由高さ、すなわち初期長さは
比較的に短く、前記レバーを揺動すると、引張りばねの
伸長量がきわめて大である。This structure has the disadvantage that the springs cannot be utilized optimally. The free height, ie the initial length, of the spring is relatively short, and when the lever is swung, the amount of extension of the tension spring is quite large.
本発明の課題は、ばねの初期長さが比較的に長く、橋板

頭に述べた種の積込み橋を改良することである。The object of the invention is to improve a loading bridge of the type mentioned at the outset, in such a way that the initial length of the springs is relatively long and the extension of the springs when the bridge deck is swung is relatively small.

てもよい。In order to solve this problem, the invention provides that the tension spring extends beyond the line connecting the pivot point of the lever on the platform and the contact point of the lever on the bridge plate, towards the front free end of the bridge. It is extending. For this purpose preferably curved or bent levers are used. Thereby, relatively long tension springs can be used. This long tension spring only grows slightly when the bridge plate pivots. Furthermore, it is possible to use a straight lever and to guide the spring to the side of the lever and to fasten it to the arm of the lever or the like.
図に基づいて本発明を更に詳しく説明する。The present invention will be explained in more detail based on the figures.

される。The bridge plate 1 is supported at its rear end so as to be pivotable about a horizontal axis 2 on a plant platform or ramp 3. The front free end of the bridge plate 1 is preferably provided with a foldable extension. During operation, the loading bridge is supported via this extension on the platform to be loaded or unloaded.

のほぼ中央において、はぼＳ字状のカム面を有するカム
板８が橋板１の下に設けられている。A lever 6 is provided below the bridge deck 1, which lever 6 is pivotably supported about a horizontal axis 7 on the bottom surface of a platform recess or pit 5 which serves to sink the bridge deck 1. This lever extends obliquely forward and upward, ie towards the free end of the bridge plate 1. Bridge board 1
A cam plate 8 having an S-shaped cam surface is provided below the bridge plate 1 at approximately the center of the bridge plate 1 .
このカム板８はレバー６の上端に支承されたローラ９に
よって付勢される。This cam plate 8 is biased by a roller 9 supported on the upper end of the lever 6.

れている。An arm 10 is fixed at about 2/3 of the height of the lever 6. The length of this arm is approximately 20% of the length of lever -6. The front end of a tension spring 11 is fixed to the free end of this arm 10. The tension spring 11 extends rearward and its rear end is fixed to the bridge plate 1 near the horizontal axis 2.

くなり、そして軸７が橋板１の後端の近くまたはその下
にあると仮定すると、伸長量△Ｌが比較的に短くなる。In FIG. 1, tension spring 11 has the shortest length LO. When the bridge plate 1 sinks, the tension spring 11 expands a certain amount. In this final length, the tension spring 11 occupies its lower end position. In this case, the tension springs are stretched or tensioned to such an extent that the tension springs 11 facilitate the pivoting up of the bridge deck 1 into the position shown in FIG. In this case, it is important to not fix the front end of the tension spring 11 directly to the lever 6, but to fix it in front of the lever 6 as seen in the direction of passage of the bridge. Thereby, the initial length of the tension spring 11 is increased and, assuming that the axis 7 is near or below the rear end of the bridge plate 1, the amount of extension ΔL is relatively short.

と゛カム板８のほぼ中間に設けられている。In the embodiment of the invention, the axis 7 is the axis 2 when the bridge is viewed from above.
It is provided approximately in the middle of the cam plate 8.
