2. Description of the Related Art Conventionally, as this kind of product, Jitsuko Sho 58
According to Japanese Patent Laid-Open No. 41208, a pair of gate suspension members, which are located inside both guide members, are fixed to a beam main body having guide members guided to the door groove at both ends, and fixed at predetermined intervals. A counter or a spring is connected to the gate suspending member, and the gate suspending member is angled and locked to the gate suspending rod of the gate to lift and lower the gate. In the publication, a slide guide, which is a guide member fitted to a rail provided in a door groove, is provided on a lifting beam so as to be slidable in a direction orthogonal to the rail, and a pair of gate suspension members interlocking with the lifting beam are provided. According to Japanese Utility Model Laid-Open No. 3-46528, there is a structure for suspending a door block of a cornering gate provided with a lift, which is rotatably supported by a lifting base and hung by its own weight. Lifting hook that locks the corner drop in the moving position, hook rotation lever that rotates the lifting hook to the non-operating position, and lifting through the hook rotation lever by contacting the upper part of the corner drop There has been proposed an attachment / detachment device for an angled hoisting hook, which comprises a push-up bar for turning the hook for hooking, and a locking member for locking the hook turning lever to hold the hoisting hook in a non-operating position. There is.

When the gate is suspended by using these things, for example, when the gate suspension member is lowered, the gate suspension member is automatically locked to the gate and can be suspended. When the gate is lowered by operation and landing, and then only the beam main body is further lowered, the gate suspension member is removed from the gate.

It And as shown in the prior art, with this type of lifting beam,
It is relatively expensive because it has a hanging member that automatically engages and disengages with the gate so that it can be easily engaged with and disengaged from the gate. That is, it is necessary to prepare a plurality of lifting beams for each of the gates having different left and right widths. And this type of corner drop gate is generally not suitable for waterways that are frequently opened and closed, and is rarely used for maintenance and maintenance of equipment attached to the waterways or when there is a failure. It was very uneconomical to keep.

Therefore, an object of the present invention is to provide a lifting beam for a gate capable of suspending a plurality of gates having different widths.
