Platform structure for assembling and dissembling carrying vehicle

Abstract

The invention discloses a platform structure for loading and unloading a carrying vehicle. The platform structure comprises load-bearing supporting leg oil cylinders, a plurality of folding plates which are sequentially arranged in parallel and a plurality of lap plates, wherein every two adjacent folding plates are connected through a hinge mechanism, and folding and unfolding functions of the folding plates are realized through a turnover connector and two telescopic oil cylinders; the connecting end of each folding plate is connected with the corresponding lap plate capable of turning over,and a space used for mounting the lap plate is reserved in the top of the connecting end of each folding plate; each lap plate is used for compensating a seam during butt-joint of the platform and arailway flatcar; each lap plate and each folding plate are connected through a folding mechanism, and the lap angle and self-locking of each lap plate are realized through the corresponding folding mechanism and the corresponding oil cylinder; and the load-bearing supporting leg oil cylinders are mounted on the bottom surfaces of the folding plates, and stretching-out and drawing-back of the load-bearing supporting leg oil cylinders are completed by pushing-pulling oil cylinders. The platform structure can be used for positively unloading and laterally loading, adopts a folding type structurewhich is relatively wide after being unfolded, does not depend on terrain, is flexible to unload, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of railway loading and unloading, in particular to a platform structure for loading and unloading vehicles. Background technique [0002] At present, in railway transportation, the loading and unloading platforms for special equipment mainly include artificially built loading and unloading platforms using sleepers and rails, light assembled railway platforms, and heavy motorized railway platforms. [0003] Using sleepers and rails to manually build loading and unloading platforms requires a lot of personnel input, high labor intensity, and low efficiency; light assembled railway platforms rely on manual erection, require a lot of personnel input, high labor intensity, and low efficiency; heavy motorized railway platforms, after the platform is unfolded The size is narrow, and wheeled and crawler-type equipment can only be loaded and unloaded along the direction of train travel, and cannot be unloaded laterally perpend...

AI Technical Summary

Problems solved by technology

[0005] 1. The passage surface of the trestle bridge is narrow, which is only suitable for mechanically driven folding trestle bridges on fixed platforms at sea. The light-bearing load can only be used for small equipment and is not suitable for loading and unloading heavy wheeled and crawler equipment on railway flat cars;

[0006] 2. It is cumbersome to lay cables, fire pipelines and other facilities on the edge of the trestle bridge;

[0007] 3. The existing technology has no load-bearing legs, is not suitable for unloading heavy equipment on railway flat cars, and has no side unloading function
