Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting technology, and in particular to a hoisting device for dual-machine lifting of H-class gas turbine equipment. Background Technology

[0002] H-class gas turbines, currently the largest single-unit gas turbine type, are increasingly widely used in construction projects in China. The high-pressure and intermediate-pressure cylinders and the lower section of the gas turbine are key structural components of H-class gas turbines, characterized by their significant weight and high installation precision requirements. They are typically hoisted using dual cranes within the main plant. For example, if an H-class gas turbine is arranged at a high position, with the gas turbine, steam turbine, and generator on the same axis, the traditional hoisting method involves parallel operation and control of two overhead cranes, lowering both hooks into the equipment transport channel, connecting the hooks to a specialized lifting tool, and then connecting the lifting tool to the equipment. However, due to the increasingly integrated layout of H-class gas turbine plant spaces and the continuous increase in the size and specifications of overhead cranes, the width of the plant's equipment transport channel is no longer sufficient for both crane hooks to be lowered to the ground simultaneously. This renders the original lifting tools unusable, compromising the installation operation of the H-class gas turbine. Summary of the Invention

Figures 1 to 6As shown, the hoisting device includes a double-machine lifting beam 3, a hydraulic lifting suspension device 4, and lifting ramps 5. The double-machine lifting beam 3 includes a box girder 31 and a first lifting lug 33 and a second lifting lug 34 symmetrically arranged on the top of the box girder 31.

The center of the first lifting lug 33 and the center of the second lifting lug 34 are 750mm from the end of the box beam 31. The two sides of the box beams 31 are connected by H-beams 32. To ensure the overall stability and dimensional accuracy of the dual-machine lifting beam 3, the box beams 31 and the H-beams 32 are bolted together. Each set of box beams 3 has a through hole 36. The first lifting lug 33 and the second lifting lug 34 are each equipped with a pin 331, a pin sleeve 332, and a pin stop 333 on both sides.

The first lifting lug 33 and the second lifting lug 34 each contain two symmetrical sets of pin-shaft lifting lugs, which are respectively connected to the special lifting ropes 24 of the two sets of lifting mechanisms 2.

[0032] Examples, such as Figure 3As shown, the suspended lifting frame includes an upper suspension device 41, a connecting frame 42, connecting struts 43, and a lower load-bearing lifting device 45.

The upper part of the triangular lifting tool has a pin connection hole, and the lower part has a pin. The component anchor 51 and the triangular lifting tool are rotatably connected by the pin. The steel strand 46 is connected to the component anchor 51. The lifting tool 52 has multiple pin holes 523 to facilitate the use of different lifting ropes. The lower part of the lifting device 5 is provided with a first pin 521 and a second pin 522.

The first lifting steel wire rope 1 is provided on the first pin 521 and the second pin 522.

[0034] During the hoisting process, the steel wire ropes 23 on both cranes remain perpendicular to the H-class gas turbine unit 1, greatly ensuring the safe load of the cranes and steel wire ropes and reducing safety risks during hoisting operations. When hoisting and transferring the H-class gas turbine unit, the two cranes can be connected in parallel for operation, requiring only one person to directly operate the trolleys on both cranes, reducing operator workload and improving the accuracy of hoisting operations.

[0035] The lifting device will be further described below with reference to its usage method. When using this utility model, the specific steps include:

[0036] Step 1: Connect the hydraulic lifting suspension device 4 to the double-machine lifting beam 3; pass the hydraulic lifting suspension device 4 through the middle hole of the double-machine lifting beam 3 from top to bottom until the hydraulic lifting suspension device 4 is lowered to the upper plane of the double-machine lifting beam 3; hoist the hydraulic lifting device 44 above the positioning middle hole of the double-machine lifting beam 3, and slowly lower it to the upper plane of the lower load-bearing lifting device 45, and connect the hydraulic lifting suspension device 4 to the double-machine lifting beam 3.

[0037] Step 2: Connect the hydraulic lifting suspension device 4 to the lifting ramp 5. The hydraulic lifting suspension device 4 is equipped with a steel strand 46, and the lower part of the lifting ramp 5 is equipped with a component anchor 51 and a special steel wire rope 6. The steel strand 46 is connected to the component anchor 51.

[0038] Step 3: Connect the H-class gas turbine equipment 6 to the hoisting platform 5; the lower part of the hoisting platform 5 is provided with a first pin 521 and a second pin 522, the first pin 521 and the second pin 522 are respectively located at both ends of the hoisting platform 5, and a first hoisting wire rope 1 is provided on the first pin 521 and the second pin 522, and the first hoisting wire rope 1 is connected to the hoisting platform 5.

[0039] Step 4: Connect the double-machine lifting beam 3 to the two sets of lifting mechanisms. Each of the two sets of cranes 21 is equipped with a second lifting wire rope 22. The lower end of each second lifting wire rope 22 is equipped with a hook 23 for lifting. The lower part of the hook 23 is equipped with a special lifting rope 24 for connecting the lifting lug. The upper part of the box beam 31 is equipped with a lifting lug for connecting with the hooks on the two sets of cranes. The lifting lug includes a first lifting lug 33 and a second lifting lug 34. The first lifting lug 33 and the second lifting lug 34 are respectively set at both ends of the box beam 31. The distance between the first lifting lug 33 and the second lifting lug 34 is equal to the distance between the hooks 23 of the two cranes. The first lifting lug 33 and the second lifting lug 34 each include two symmetrical sets of pin-shaft lifting lugs. The first lifting lug 33 and the second lifting lug 34 are connected to the special lifting rope 24.

[0040] Step 5: The hydraulic lifting device 44 lifts the H-class gas turbine unit 6. The hydraulic lifting device 44, through the steel strands 46, synchronously moves the lifting platform 5 upwards, lifting the H-class gas turbine unit 6 off the ground, until the hydraulic lifting device 44 reaches its maximum upward position. After the hydraulic lifting device 44 lifts the steel strands 46 and tauts them, the stress on each steel strand 46 needs to be checked, and any unstressed steel strands 46 need to be pre-tightened to ensure uniform stress. When the H-class gas turbine unit 6 is lifted 500mm off the ground, the connection points between the steel strands 46 and the hydraulic lifting device 44 and lifting platform 5 need to be inspected.

[0041] Step Six: Two sets of cranes lift the H-class gas turbine unit 6; the two sets of cranes synchronously drive the lifting platform 5 upward, driving the H-class gas turbine unit 6 above the positioning plane.

[0042] Step 7: Lowering and installing the H-class gas turbine equipment 6; Two sets of cranes synchronously drive the lifting platform 5 to move downwards until the H-class gas turbine equipment 6 falls onto the foundation platform. After the H-class gas turbine equipment 6 has completely fallen onto the foundation platform, disconnect the first hoisting wire rope 1 from the H-class gas turbine equipment 6.

[0043] The above description is merely one embodiment of this utility model, and while it is quite specific and detailed, it should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
