A slide rail 17 is fixed on the other side of the lower surface of the platform 18, a slide rail seat 16 is installed on the slide rail 17, and the second support rod 11 slides on the slide rail 17 through the slide rail seat 16.

The middle position of the first supporting rod 10 and the middle position of the third supporting rod 12 rotate mutually through a fifth movable rotating shaft 25, and the middle position of the second supporting rod 11 and the middle position of the fourth supporting rod 13 rotate mutually through a sixth movable rotating shaft 26. One end of a hydraulic pump 21 is fixed on a support rod 19 between the upright rods 2 through a rotating seat 20, the support rod 19 can also be fixed between mutually parallel support rods of the square frame 1, and one end of a hydraulic cylinder 21 rotates on the support rod 19 through the rotating seat 20. The push rod at the other end of the hydraulic cylinder 21 can rotate at the middle position of the horizontal connecting rod 22 through a third movable rotating shaft 23. The hydraulic cylinder 21 may be an electric hydraulic cylinder connected to a lift button box provided on the platform 18, or a mechanical hydraulic cylinder having an operating handle provided on the platform 18.

The construction platform is pushed to an elevator well mouth through the idler wheel 7, the construction platform is hung and placed in an elevator shaft through the hoisting tower, and the construction surface of the construction platform is adjusted to be in a horizontal state by the length of the adjusting screw 6 extending out of the square frame 1. When the hydraulic pump 21 is an electric hydraulic pump, a lift button provided on the platform 18 is pressed, and a push rod of the hydraulic pump 21 pushes the horizontal connecting rod 22 to move upward. The first support rod 10, the second support rod 11, the third support rod 12, the fourth support rod 13, the first movable rotating shaft 14, the second movable rotating shaft 15, the fifth movable rotating shaft 25 and the sixth movable rotating shaft 26 are combined together to form two groups of superposed X-shaped support structures.

X type supporting structure progressively changes from folding the horizontal condition into propping up the vertical condition like this, promotes platform 18 progressively upward movement to make things convenient for constructor construction, reduced because of constructor takes the time waste that transport equipment of ascending a height caused, platform 18 fixes on the bottom support through X type supporting structure simultaneously, and constructor stands and can be more firm on platform 18, safer.

A descending button arranged on the platform 18 is pressed, a push rod of a hydraulic cylinder 21 pulls a horizontal connecting rod 22 to move downwards, the X-shaped support structure is folded downwards, and one end of a first supporting rod 10 rotates on the sliding seat 9 and simultaneously drives the sliding seat 9 to horizontally move towards the opposite direction of one end of a third support in the sliding groove 8; one end of the second support rod 11 rotates on the slide rail seat 16, and simultaneously drives the slide rail seat 16 to horizontally move on the slide rail 17 in the opposite direction to one end of the fourth support rod 13. The X-shaped frame structure is thus gradually transformed from an erected vertical position to a folded horizontal position, pulling the movable platform 18 gradually downwards.

The X-shaped support structure can be formed by combining one or more groups of X-shaped supports, the lifting height of the X-shaped support structure supporting platform 18 can be set to be the height of a two-layer floor, and a constructor can construct two layers and then upwards improve the construction platform through the tower crane, so that the number of times of lifting the height of the construction platform through the tower crane can be reduced, and the construction efficiency is improved.

The above description is for further details of the present invention, and the detailed implementation of the present invention is not limited to these descriptions, and for those skilled in the art to which the present invention pertains, the present invention can be easily replaced, modified and changed without departing from the inventive concept of the present invention, and all of the simple replacements, modifications and changes should be considered as belonging to the protection scope of the present invention.
