Description

Technical Field

[0001] The present invention belongs to the technical field of high-altitude steel structure construction, and in particular, relates to a special hanging basket for hoisting a high-altitude steel structure platform for a solar thermal project. Background Art

[0002] Currently, in CSP projects, high-altitude steel structure platforms serve as the core carriers for the installation, overhaul, maintenance, and material transportation of key equipment. For example, in tower-type CSP power stations, the cantilevered steel platform outside the absorber tower serves as a docking platform for the tower crane's overhaul cage and a temporary storage platform for absorber maintenance equipment and materials. When the absorber tower steel structure is constructed to this platform, completing the platform construction as soon as possible can provide a safe isolation layer for the construction of the tower's external structure above the absorber concrete. This can catch any falling materials during the construction of the external structure, and provide a safe working environment for the normal construction of buildings around the base of the absorber tower. However, existing high-altitude steel structure platforms face challenges such as complex structural design, high operating heights, and high risks of aerial operations. In addition, high-altitude steel structure platforms often play a transitional role in the overall construction process, and their efficient and safe lifting directly affects the project progress and the safety of construction personnel. Currently, there is not much basis for the hoisting of high-altitude steel structure platforms for solar thermal projects. Traditional hanging basket work platforms have problems such as poor structural adaptability, insufficient safety protection, and low installation efficiency when dealing with large-span cantilevered steel structures and multi-angle welding.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, the present invention provides a special hanging basket for hoisting high-altitude steel structure platforms for solar thermal projects. It includes an upper support frame 1, a lower working frame 2, and support uprights 3. The upper support frame 1 is welded from an outer support beam 101, an intermediate longitudinal beam 102, and an inner support beam 103. The bottom of the lower working frame 2 is paved with patterned steel plates 7 to facilitate welding operations. One end of the support upright 3 is welded to the upper support frame 1, and the other end is welded to the lower working frame 2, forming the entire hanging basket framework. This special hanging basket for hoisting high-altitude steel structure platforms for solar thermal projects is generally shaped like a shoulder pole.

[0029] The support rods 3 include a first support rod 301, a second support rod 302, a third support rod 303, a fourth support rod 304, a fifth support rod 305, a sixth support rod 306, a seventh support rod 307, and an eighth support rod 308, which are arranged in a fan-shaped pattern. A support step 4 and a first connecting rod 501 are provided between the first support rod 301 and the second support rod 302, a second connecting rod 502 is provided between the third support rod 303 and the fourth support rod 304, a third connecting rod 503 is provided between the fifth support rod 305 and the sixth support rod 306, and a fourth connecting rod 504 is provided between the seventh support rod 307 and the eighth support rod 308.

[0030] Internal support steps 6 are provided between the first support rod 301 and the fifth support rod 305, between the second support rod 302 and the sixth support rod 306, between the third support rod 303 and the seventh support rod 307, and between the fourth support rod 304 and the eighth support rod 308. These steps facilitate workers to enter another lower work platform frame from one lower work platform frame through the cantilevered steel platform main structure.

[0031] In order to prevent objects from falling from high altitude and improve the safety of use during the use of the present invention, a bottom safety net and a dense mesh net 8 are installed in sequence on the side and lower surface of the hanging basket body.

[0032] The design angle of the main body of the special hanging basket for hoisting the high-altitude steel structure platform of the solar thermal project is consistent with the installed high-altitude steel structure platform, which can accurately carry out high-altitude in-place welding of the high-altitude steel structure platform.

[0033] In order to cooperate with the high-altitude steel structure platform to be installed and meet the circular structure of the tower body on which the high-altitude steel structure platform acts, the special hanging basket for the high-altitude steel structure platform is designed as a fan-shaped + shoulder pole structure, so as to achieve the purpose of rapid lifting and maximizing the convenience of use. Figure 7 As shown, when using the special hanging basket for high-altitude steel structure platform hoisting, it is hoisted onto the assembled high-altitude steel platform hoisting unit on the ground, and four sets of channel steel clamps are used to fix the hanging basket and steel structure hoisting unit into a whole. The 60T tower crane 12 is used in conjunction with the relevant lifting locks to hoist the high-altitude steel platform hoisting unit and hanging basket combination to the designed position.

[0034] like Figure 8 As shown, this is an embodiment of the present invention and the combined hoisting of the cantilevered steel platform outside the heat absorption tower. According to the structural design of the concrete 10 of the heat absorption tower, three ventilation and air conditioning reserved windows 11 are opened thereon, and the lower plane of the window is flush with the 176m platform elevation. In order to facilitate the hoisting of the 176m cantilevered steel platform outside the tower, and considering that the construction of the 176m heat absorption tower inner platform 13 has been completed when the outer cantilevered steel platform is hoisted, the operating personnel can pass through the inner platform 13 of the heat absorption tower, through the ventilation and air conditioning reserved windows 11, and enter the structure where the outer cantilevered steel platform is hoisted to the positioning height for welding. The hoisting unit on the easternmost side is defined as the first hoisting unit, and the second to eleventh hoisting units are hoisted into place in sequence. In actual use, the present invention does not produce 11 sets of a full circle of special platforms to cooperate with the hoisting of the outer cantilevered steel platform units. In actual use, only 3 sets need to be produced, and repeated recycling can meet the needs of on-site construction.

[0035] The method for using the special hanging basket for hoisting the high-altitude steel structure platform of the solar thermal project provided by the present invention includes: hoisting the hanging basket to the assembled high-altitude steel platform hoisting unit on the ground, and fixing the hanging basket and the steel structure hoisting unit into a whole with 4 sets of channel steel clamps. The 60T tower crane 12 is used in conjunction with relevant lifting locks to hoist the high-altitude steel platform hoisting unit and the hanging basket assembly to the designed position. After the first hoisting assembly is in place, the operator begins to enter the hanging basket to weld the steel beams of the high-altitude steel platform, and then uses the 60T tower crane 12 to continue hoisting the second and third hoists assembled on the ground. When hoisting to the fourth hoist, the steel beams of the first hoist have been basically welded, so the hanging basket can be lifted out of the welded first hoisting structure, and after returning to the ground, it continues to be combined with the fourth hoisting structure to form a hoisting assembly. And so on, the recycling process of the other two sets of special hanging baskets for hoisting high-altitude steel structure platforms is deduced.

[0036] The initial design weight of the special hanging basket for hoisting high-altitude steel structure platforms is 300Kg, and the maximum load weight is 300Kg (including one operator and some construction tools on the upper part). After ANSYS finite element stress analysis, it meets the safety load requirements.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
