[0035] Reference Figures 1 to 3 As shown, the utility model discloses a lifting frame for vertically lifting the heating surface module of the waste heat boiler of a gas turbine. The lifting frame includes:
[0036] The main body 100 has a first end and a second end that are opposite to each other. The first end and the second end form a support section 110. The heating surface module of the waste heat boiler of the gas turbine can be installed in the support section 110. The support section 110 can provide rigid support for the heating surface module of the waste heat boiler of the gas turbine;
[0037] The ground-supporting portion 300 is provided at the first end of the main body 100 and is used for supporting the ground during the vertical lifting process;
[0038] The hoisting portion 400 is provided at the second end of the main body 100 and is used to connect to a lifting device;
[0039] The bearing portion 500 is provided at the second end and is used to be connected to the heating surface module of the waste heat boiler of the gas turbine to bear the heating surface module of the waste heat boiler of the gas turbine.
[0040] The installation process of vertically hoisting the heating surface module of the waste heat boiler of a gas turbine using the lifting frame of the present invention is as follows:
[0041] When the gas turbine waste heat boiler heating surface module is installed from a horizontal state to a vertical state, the gas turbine waste heat boiler heating surface module body (not shown in the figure) and the packaging rack 220 are installed together on the support section 110. The support section 110 provides rigid support for the gas turbine waste heat boiler heating surface module. Rigid support means that the support section 110 will not deform during the support process. This prevents the gas turbine waste heat boiler heating surface module from deforming during the hoisting process. Among them, the support section 110 adopts a rigid support structure, such as a steel beam structure with a certain rigidity. This ensures that the gas turbine waste heat boiler heating surface module will not deform when supporting it.
[0042] The upper end of the HRSG heating surface module is connected to the support portion 500, which is hoisted to support the weight of the HRSG heating surface module. The upper end of the HRSG heating surface module and the support portion 500 can be connected using various connection structures.
[0043] During the hoisting process, the ground-supporting part 300 supports the ground to provide support for the entire structure. The hoisting part 400 is connected to relevant lifting equipment such as a crane, and the lifting frame is gradually adjusted from a horizontal state to a vertical state through the lifting equipment. Until the lifting frame is in a vertical state, the ground-supporting part 300 supports the ground to provide support for the entire structure. Under the supporting effect of the ground, the hoisting force between the upper end of the heating surface module of the waste heat boiler of the gas turbine and the bearing part 500 can be reduced, the stress condition of the bearing part 500 can be optimized, and safety can be improved. It can also provide a certain positioning effect for the entire structure. Avoid swinging during the hoisting process of the entire structure.
[0044] By adopting the lifting frame of the present invention, a stable rigid support can be provided for the heating surface module of the waste heat boiler of the gas turbine with a slender and flexible structure, ensuring that the module will not be deformed or damaged due to its own structure during the installation process.
[0045] In some embodiments of the present invention, the main body 100 includes two rigid beams 120 , which are arranged parallel to each other to form an installation surface for installing the heating surface module of the gas turbine waste heat boiler. The two rigid beams 120 are connected by a connecting beam 130 .
[0046] In this embodiment, the upper plane formed by two rigid beams 120 arranged parallel to each other serves as the mounting surface for the waste heat boiler heating surface module. The two rigid beams 120 are connected by a connecting beam 130, which connects the two rigid beams 120 into one body and ensures the overall structural strength. The rigid beams 120 can be steel beams or other materials with sufficient strength. Steel beams are preferably used in this embodiment, as they have the advantages of high structural strength and low cost. Furthermore, the steel beams can be fixed to the packaging rack 220 by welding, thereby fixing the packaging rack 220 to the steel beams. This prevents the waste heat boiler heating surface module from shaking during the hoisting process. When necessary, the steel beams are fixed to the packaging rack 220 by welding. After the hoisting work is completed, the steel beams and the packaging rack 220 are cut apart to facilitate the reuse of the lifting rack.
[0047] In some embodiments of the present invention, the first ends of the two rigid beams 120 are both set as arc ends 140. In this embodiment, the first ends of the two rigid beams 120 are both set as arc ends 140, that is, the end supported by the ground adopts an arc design. In this way, during the hoisting process, in the process of transitioning from a horizontal state to a vertical state, since the arc end 140 is in contact with the ground, the arc end 140 is always in arc surface contact with the ground. The arc surface contact reduces the resistance of the arc end 140 to the ground as much as possible. The bearing part 500 is placed in a relatively gentle stress state, and there will be no large force changes. The hoisting force between the upper end of the heating surface module of the waste heat boiler of the gas turbine and the bearing part 500 is reduced, thereby improving safety.
[0048] In some embodiments of the present invention, the ground supporting portion 300 includes two supporting beams 310 and a ground supporting beam 320. The two supporting beams 310 are respectively arranged on two rigid beams 120 and are arranged perpendicular to the rigid beams 120. The two supporting beams 310 are connected through the ground supporting beam 320. The end face of the ground supporting beam 320 facing away from the second end and the end face of the arc end 140 constitute a ground supporting surface 330. The ground supporting surface 330 is perpendicular to the installation surface.
[0049] In this embodiment, after the HRSG heating surface module is hoisted from a horizontal position to a vertical position, the support surface 330 formed by the support beams 320 and the arc ends 140 provides support for the entire structure. Furthermore, because the support surface 330 is perpendicular to the installation surface, the HRSG heating surface module remains vertical, thereby ensuring smooth installation of the HRSG heating surface module.
[0050] In some embodiments of the present invention, a reinforcement beam 340 is provided between the support beam 310 and the rigid beam 120. In this embodiment, by providing the reinforcement beam 340 between the support beam 310 and the rigid beam 120, the support strength of the support beam 310 is improved.
[0051] In some embodiments of the present invention, the hoisting unit 400 includes a lifting lug 410 and a hoisting rope (not shown). The second ends of the two rigid beams 120 are each provided with a lifting lug 410, and the ends of the hoisting rope are connected to the lifting lug 410. In this embodiment, the hoisting unit 400 is composed of the lifting lug 410 and the hoisting rope. When the hoisting unit 400 is connected to the hoisting equipment, the hoisting hook of the hoisting equipment is connected to the hoisting rope. The hook, hoisting rope, and lifting lug 410 work together to vertically lift the entire structure.
[0052] In some embodiments of the present invention, the load-bearing portion 500 includes a load-bearing bracket 510 and a load-bearing connector 520. The load-bearing bracket 510 is disposed at the second ends of the two rigid beams 120, and the load-bearing bracket 510 is disposed on the load-bearing connector 520. In this embodiment, the weight of the heat recovery steam heating surface module is borne by the load-bearing bracket 510 and the load-bearing connector 520, and the upper end of the heat recovery steam heating surface module and the load-bearing connector 520 are supported by the load-bearing bracket 510 and the load-bearing connector 520.
[0053] In some embodiments of the present invention, the load-bearing connector 520 is a connecting pin, and the waste heat boiler heating surface module is provided with a connection hole that is compatible with the connecting pin. In this embodiment, the load-bearing connector 520 is a connecting pin that connects to the connection hole on the heat boiler heating surface module to complete the connection between the upper end of the heat boiler heating surface module and the load-bearing portion 500.
[0054] In some embodiments of the present invention, the two rigid beams 120 are provided with fixing members near the first ends thereof for fixing the lower ends of the heating surface modules of the waste heat boiler of the gas turbine.
[0055] To prevent the lower portion of the gas turbine waste heat boiler heating surface module from shaking during the hoisting process, in this embodiment, a fixing member is provided on the rigid beam 120 near the first end to fix the lower end of the gas turbine waste heat boiler heating surface module. The fixing member can be a connecting member consisting of a pin shaft and a pin hole that cooperate with each other. In addition, a detachable connection structure can also be used to fix the lower portion of the gas turbine waste heat boiler heating surface module. After the gas turbine waste heat boiler heating surface module is installed, it can be disassembled without affecting the reusability of the lifting frame.
[0056] In some embodiments of the present invention, the two rigid beams 120 are metal parts, and the lower end of the heating surface module of the waste heat boiler of the gas turbine can be welded and fixed to the rigid beam 120.
[0057] In this embodiment, the rigid beam 120 is a metal beam and can be fixed to the packaging rack 220 by welding, so that the packaging rack 220 is fixedly connected to the steel structure beam. This prevents the lower part of the gas turbine waste heat boiler heating surface module from shaking during the hoisting process. The rigid beam 120 is specifically a steel structure beam. It should be noted that welding fixation is mainly to prevent the gas turbine waste heat boiler heating surface module from shaking during the hoisting process, so the welding position only needs to be at the lower position. After the installation is completed, the welded part can be cut open. It does not affect the reuse of the lifting frame.
[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
