[0036] The implementation principle of the triangular truss and the climbing formwork construction device of the bridge lifting platform for the concrete cylinder wall of the heat absorption tower in the embodiment of the present application is as follows: During the construction of the heat absorption tower cylinder wall, first, the inner formwork 31 and the outer formwork 32 are assembled. After the inner formwork 31 and the outer formwork 32 are assembled, the inner formwork 31 and the outer formwork 32 are fixed on the heat absorption tower cylinder wall that has been poured by the tie rod 3311, the hollow sleeve 3312 and the limit nut 3313. Then, the staff on the platform operation component 21 pour concrete into the annular pouring cavity 34. After the concrete is cured and formed, the hydraulic station 221 and the through-hole jack 223 are adjusted. The through-hole jack 223 climbs along the support rod 222, and the through-hole jack 223 drives the bridge lifting platform 1 to rise. The bridge lifting platform 1 drives the platform operation component 21 and the lifting component 23 to rise synchronously. Continue to tie the steel bars and remove the lowermost inner formwork 31 and outer formwork 32. Subsequently, the horizontal adjusting part 233 is adjusted. The horizontal adjusting part 233 drives the lowermost inner formwork 31 and the lowermost outer formwork 32 to move away from the heat absorption tower cylinder wall. Then, the hydraulic cylinder 231 is adjusted. The piston rod of the hydraulic cylinder 231 drives the lifting ring 232 to rise. The lifting ring 232 drives the horizontal adjusting part 233 to rise synchronously. The horizontal adjusting part 233 drives the lowermost inner formwork 31 and the lowermost outer formwork 32 to rise synchronously, and rises above the inner formwork 31 and the outer formwork 32 that are still fixed to the heat absorption tower cylinder wall. The horizontal adjusting part 233 is adjusted again. The horizontal adjusting part 233 drives the lowermost inner formwork 31 and the lowermost outer formwork 32 to move towards the heat absorption tower cylinder wall, forming a new annular pouring cavity 34. Repeat the above operations until the required height of the heat absorption tower is poured.

[0037] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
