[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the lifting cylinder 8, small cylinder 13 and motor 25 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0032] The drawings in the specification of this application are for illustration only, and the sizes and shapes of the components shown therein are not actually limited, but are only for illustration. In the actual implementation process, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0033] The working principle and usage process of this technical solution are as follows: When it is used for the first time, multiple main trusses 101 and secondary trusses 102 are spliced ​​and installed by bolts on the roof of a high-rise building according to the design drawings to form a complete truss platform 1, ensuring that all connection points are reliably fastened to ensure the stability and safety of the platform structure, and then the upper platform 2 (a rigid platform) is fixedly installed on the top of the truss platform 1, and a fence 3 is set on the top outer ring of the upper platform 2 to ensure the safety of personnel, and then a plurality of connecting rods 4 are welded on the bottom outer ring of the upper platform 2, and then the lower platform 5 (a rigid platform) is welded on the plurality of connecting rods 4, so that the lower platform 5 is located below the truss platform 1; Then install the four lifting mechanisms, support mechanisms and anti-fall components (such as Figure 5 As shown in FIG. 1 ), the upper support frame 6 is installed in a rectangular shape at the bottom of the truss platform 1, and then the multiple small oil cylinders 13 on both sides of the upper support box beam 7 and the lower support box beam 10 are started simultaneously. The eight small oil cylinders 13 are started simultaneously so that their output ends push the support legs 11 out through the slider (as shown in FIG. 1 ). Figure 6 As shown), the eight protruding legs 11 are respectively inserted into the reserved holes on the two side walls, and the overall support and fixation of the platform is completed. Then, a temporary yard with reinforced steel structure is set on the upper platform 2, and a material placing machine and a waste yard are set on it. The central control room, batching room, material yard, welding room and power distribution room are set on the lower platform 5; Then, slide rails 27 are installed at the four corners of the bottom of the truss platform 1, and the hanger 28 and the connecting frame 30 and the frame plate 31 thereon are installed on the slide rails 27, so that the hanger 28 as a whole can be moved on the slide rails 27 through the rollers 29, which can meet the requirement of the hanger 28 as a whole moving inward when the outer wall is retracted, and is used to complete the decoration of the poured concrete layer, the erection formwork and the retreat of the concrete layer to be poured, and at the same time, the steel bar binding of the upper layer of the concrete layer to be poured can be completed; When it is necessary to lift the truss platform 1, first clear the weight and debris on the upper platform 2. After the cleaning is completed, start the sixteen small oil cylinders 13 on the four upper support box beams 7 at the same time, and control their output ends to retract. When the output ends of the sixteen small oil cylinders 13 retract, all the legs 11 are driven to retract into the upper support box beam 7 through the slider. At this time, control the four lifting cylinders 8. The output ends of the four lifting cylinders 8 simultaneously push the upper support box beam 7 and the upper support frame 6 to rise. When the upper support box beam 7 and the upper support frame 6 rise, they push the truss platform 1 and the objects thereon to rise at the same time. When the upper support box beam 7 is lifted by one floor height to the reserved opening, the four upper support box beams The sixteen small oil cylinders 13 on the upper support box beam 7 are started at the same time, and all the legs 11 are pushed out from the upper support box beam 7 and inserted into the reserved hole through the output ends thereof. When the upper support box beam 7 is supported in place, the sixteen small oil cylinders 13 on the four lower support box beams 10 are started at the same time according to the above-mentioned operation principle and process to retract the legs 11, and the four jacking oil cylinders 8 are started to retract their output ends to drive the lower support box beam 10 to rise one floor height to the reserved hole. The sixteen small oil cylinders 13 push all the legs 11 out from the lower support box beam 10 and insert them into the reserved hole for fixing through the output ends thereof, thereby completing the jacking process of the truss platform 1; When the upper supporting box girder 7 rises, the sleeve 16 at the bottom thereof will be driven to rise synchronously. At this time, the claw 20 rises together with the sleeve 16 on the connecting seat 17. When one end of the claw 20 inserted into the slot 15 passes by the step on the slot 15 of the guide rod 14 during the rising process, it will be pushed out by the step. At this time, the torsion spring 22 is deformed by the force. When the claw 20 passes over the step and enters the next slot 15, the torsion spring 22 drives the claw 20 to rotate through its own elastic principle so that one end of it is again inserted into the corresponding slot 15. If an emergency situation causes the jacking mechanism to fail or the jacking cylinder fails and the cylinder slips, the claw 20 will quickly get stuck in the slot 15 and lock it to prevent the platform from falling. When the supporting box beam 10 rises, the motor 25 is started at the same time, and one end of its output shaft drives the driving block 26 to rotate toward the protrusion 23. When the output shaft drives the driving block 26 to rotate, it will first contact with the protrusion 23, and then push the protrusion 23 to drive the rotating rod 19 to rotate. When the rotating rod 19 rotates, it will drive the claw 20 to rotate and disengage from the corresponding slot 15 (at this time, the torsion spring 22 is deformed by the force). After the fixing of the supporting box beam 10 is completed, the electric motor 25 rotates in the opposite direction, so that the driving block 26 disengages from the contact between the protrusion 23 and returns to its original position. At the same time, the torsion spring 22 drives the claw 20 to reset and snap into the corresponding slot 15 through the limit block 21 and the rotating rod 19 through its own elastic principle; After the platform is raised to the right position, the construction workers can work on the upper platform 2, and when descending, they can just operate in the reverse direction according to the above operating principle.

[0034] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
