Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of tank container upper operating platform structures. BACKGROUND

[0002] Tank container is composed of box and frame, which is suitable for highway-railway-waterway intermodal transport. The loading and unloading pipeline, safety accessories, loading and unloading accessories, instruments and other equipment of general tank container are arranged at one end of the end head, and are protected by the valve box, the frame end frame and the door end. When the tank container is stacked due to site restrictions or other reasons, if the upper tank container equipment needs to be operated, it is difficult to operate smoothly standing on the end ladder, and an additional ladder is needed or the tank container needs to be lifted and then operated on the ground. To reduce these additional procedures, a reversible operating platform is needed to be set on the upper part of the end frame to provide a place for the operator to operate the upper tank container equipment.

[0003] The conventional operating platform has an anti-slip walk plate inserted in the middle of the platform skeleton structure, and a lifting chain connecting seat is welded at both ends. Two iron chains pass through the connecting seat and the connecting seat below the end beam to achieve the weight-bearing and fixing effect after the operating platform is turned down. When the operating platform is closed, it is fixed by the container door lock. Due to the structural design, the connecting seat of the operating platform cannot be too large, which results in a small length of the weld between the connecting seat and the operating platform, and the failure risk is high in long-term use. In actual production, it is found that due to manufacturing errors, the anti-slip walk plate will have an interference fit during installation, which is very laborious. In addition, when designing the end frame, the distance between the root of the diagonal brace and the upper end beam after welding may be smaller than the length of the folded iron chain, and the distance between the end surface of the diagonal brace and the surface of the operating platform may also be smaller than the width of the iron chain when the operating platform is closed. At this time, the operating platform cannot be closed due to the obstruction of the iron chain, which needs to be controlled, thereby limiting the design of the tank container. SUMMARY
