The working principle of the invention is as follows:
when the adjustable support structure 3 is mounted on the end platform, the adjustable support structure 3 can freely rotate at the lower end of the platform end span 2 due to the existence of a rotating shaft.
When the end platform is in a non-working state, the platform end span 2 is folded downwards to the lower part of the platform midspan 1, and the adjustable supporting structure 3 can rotate freely, so that when the platform end span 2 is folded, the adjustable supporting structure 3 is driven to rotate upwards. When the platform end span 2 is fully folded, the gap between the platform end span 2 and the platform midspan 1 is larger than the thickness of the adjustable supporting structure 3, and the adjustable supporting structure 3 is positioned in the gap between the platform end span 2 and the platform midspan 1 and is in a horizontal state.
When the end station is in operation, station end span 2 is folded upwardly until it remains level with the plane of station midspan 1. While the platform end span 2 rotates, the adjustable support structure 3 loses the support force of the platform end span 2 and rotates freely downwards until the adjustable support structure 3 reaches a free vertical state. When the adjustable supporting structure 3 is vertical, the supporting surfaces 13 at the lower ends of the supporting brackets 12 at the two sides are contacted with the upper end surfaces of the rails at the two sides.
At this time, the adjustable supporting structure 3 is in a working state, and the telescopic rod of the control oil cylinder 9 extends out, so that the upper end platform can gradually move upwards under the guiding action of the guide shaft 10. When the working position is reached, the cylinder 9 stops extending the telescopic rod. When the end station is erected, one end of the end station can leave the rail surface, and the No. 1 platform plate is inserted into the lower part of the station erected at the straight top end.
When the end platform is not working any more, the telescopic rod of the control oil cylinder 9 is retracted, and the end platform starts to gradually descend. After the descent is completed, the platform end span 2 is controlled to fold and retract, and meanwhile, the adjustable supporting structure 3 is also retracted into a gap between the platform end span 2 and the platform midspan 1 to wait for the next work.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
