[0001] This application relates to the field of auxiliary equipment technology for gas-fired power plants, and in particular to a heavy equipment hoisting device and a main equipment hoisting system for gas-fired power plants. Background Technology

[0002] The gas-fired power plant mainly includes main equipment such as steam turbines, gas turbines, gas turbine generators, and steam turbine generators. The gas turbines and gas turbine generators, when delivered as a complete unit, weigh over 300 tons; the steam turbine generators, when delivered as a complete unit, weigh nearly 300 tons; and the steam turbines, when delivered as a complete unit, weigh nearly 200 tons. For the hoisting of such large equipment, large crawler cranes are currently generally used. The equipment is "threaded" through pre-drilled openings in the plant walls, and another crane is used in conjunction with pre-drilled openings in the roof for lifting. A single crane is insufficient for directly hoisting such heavy equipment, posing a significant risk of equipment damage during the hoisting process and incurring high machinery rental costs.

Therefore, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0026] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0027] like Figures 1 to 3 As shown, this application constructs a heavy equipment hoisting device 1, which can perform hoisting operations on heavy equipment weighing hundreds of tons. The heavy equipment hoisting device 1 may include a hoisting frame 10, a drive mechanism 30, and multiple hoisting mechanisms 20. The hoisting frame 10 defines a hoisting space 100 for accommodating the heavy equipment. The hoisting mechanisms 20 are spaced apart at the top of the hoisting frame 10, and their connecting ends extend retractably into the hoisting space 100 for hoisting heavy equipment. The drive mechanism 30 is disposed on the hoisting frame 10 and is connected to the multiple hoisting mechanisms 20 respectively, for synchronously driving the multiple hoisting mechanisms 20.

[0028] This application, by setting multiple lifting mechanisms 20 on the lifting frame 10, enables the coordinated operation of these mechanisms to lift heavy equipment. By incorporating a drive mechanism 30, the multiple lifting mechanisms 20 can be driven synchronously, facilitating synchronized extension and retraction of their connecting ends and ensuring stable lifting of heavy equipment. Furthermore, by providing a lifting frame 10 with a lifting space 100, the application can stably support the lifting mechanisms, eliminating the need for pre-drilling holes in the factory walls during lifting, thus reducing the requirements for on-site civil engineering.

[0029] like Figure 2 As shown, in some embodiments, the hoisting frame 10 may be in the shape of a gate, and may include a top wall 11, a first side wall 12, and a second side wall 13. The first side wall 12 and the second side wall 13 are arranged in parallel on opposite sides of the top wall 11, and the three together define a hoisting space 100 with openings at both ends.

[0030] By setting the hoisting space 100 to be open at both ends, it is easier for heavy equipment to enter and exit, thus improving the convenience of hoisting operations.

[0031] Of course, in some embodiments, the hoisting frame 10 may also include a plurality of reinforcing members 14, which may be detachably connected between the first side wall 12 and the second side wall 13 to improve the stability of the hoisting frame 10 support.

[0032] During use, the user can first transport the heavy equipment to the hoisting space 100, and then connect the reinforcing member 14 between the first side wall 12 and the second side wall 13. Further, the heavy equipment can then be hoisted using the hoisting mechanism 20.

[0033] Furthermore, the top wall 11, the first side wall 12, and the second side wall 13 can all be assembled from several steel sections. The lifting frame 10 constructed from these steel sections reduces the overall weight while providing strong support and stability, facilitating operation and transportation. During operation, the lifting frame 10 can be brought in and out of the site by transporting the steel sections to the lifting site for assembly, reducing the need for on-site space and expanding the applicability of the heavy equipment lifting device 1.

[0034] exist Figure 1 and Figure 2 In the illustrated embodiment, the hoisting frame 10 is generally a hollow rectangular body with a rectangular top wall 11. A rectangular frame is defined by multiple steel sections connected end-to-end, and at least two steel sections are connected in the middle of the frame for mounting the hoisting mechanism 20 and the drive mechanism 30. The first side wall 12 and the second side wall 13 can be composed of multiple vertically arranged and spaced-apart steel sections, with their top ends connected to the outer periphery of the top wall 11.

[0035] Furthermore, the hoisting frame 10 may also include a plurality of reinforcing ribs 15, which may be disposed between two connected steel sections in the top wall 11, the first side wall 12 and the second side wall 13, so as to further improve the structural strength of the hoisting frame 10.

[0036] It should be understood that the top wall 11, the first side wall 12, and the second side wall 13 formed by the steel assemblies have many connection methods, which will not be elaborated here. The reinforcing rib 15 and the reinforcing member 14 can be the same type of steel as the steel structure in the top wall 11, the first side wall 12, and the second side wall 13, or they can be steel with different structures, or they can be other structural members such as rods or plates, which are not specifically limited here.

[0037] In some other alternative embodiments, the hoisting frame 10 may also be a hollow cylindrical, cylindrical, polygonal, irregular, or other frame structures. The top wall 11, and / or the first side wall 12, and / or the second side wall 13 may also be configured as a plate structure, a mesh structure, or other non-frame structures.

[0038] It should be understood that the various steel sections in the top wall 11, the first side wall 12, and the second side wall 13 of the hoisting frame 10 can be assembled using various methods such as bolt connection and welding, without specific limitations here.

[0039] like Figure 1 As shown, in some embodiments, the end of the hoisting frame 10 opposite to the hoisting mechanism 20 may also be provided with multiple moving mechanisms 40. By providing moving mechanisms 40, the hoisting frame 10 can be movably set, thereby facilitating the adjustment of the specific position of the heavy equipment hoisting device 1 at the hoisting site.

[0040] Specifically, the mobile mechanism 40 can be implemented using existing mobile devices such as casters, rollers, and small tanks, without any specific limitations.

[0041] It is important to understand that current technologies use large crawler cranes to lift heavy equipment. However, large crawler cranes require a lot of space for crane boom assembly, load testing, crane positioning, and lifting rotation. For gas-fired power plant projects that aim for a compact layout, coordinating the entry and exit of crawler cranes will cause significant disruption to the construction of surrounding plant buildings.

[0042] By setting up the moving mechanism 40, the entry and exit operations of the heavy equipment hoisting device 1 can be simplified, reducing the space occupied, so as to adapt to the gas-fired power plant project that pursues a compact layout.

[0043] In some embodiments, the heavy equipment hoisting device 1 may further include a guardrail 50 and a ladder 60. The guardrail 50 is disposed circumferentially at the top of the hoisting frame 10 to protect workers located at the top of the hoisting frame 10. The ladder 60 is disposed on one side of the hoisting frame 10, with its top extending to the top wall 11 of the hoisting frame 10 and its bottom located at the bottom of the hoisting frame 10, allowing workers to climb to the top of the hoisting frame 10 for assembly, inspection, maintenance, and operation of the hoisting mechanism 20 and drive mechanism 30 located at the top of the hoisting frame 10.

[0044] In some embodiments, the lifting mechanism 20 may employ an existing tension jack, on which at least one tension strand 22 is mounted. The connecting end of the tension strand 22 extends telescopically into the lifting space 100, and the tension jack can lift the heavy equipment connected to its connecting end by moving the tension strand 22.

[0045] Specifically, the connecting end of the tensioned strand 22 can be provided with a connecting structure 23 for connecting heavy equipment. This connecting structure 23 can be a large, flexible ring structure to be fitted onto the heavy equipment. It can also be a smaller, flexible or rigid ring structure for fitting or attaching to the connecting parts of the heavy equipment, such as lifting lugs. Alternatively, it can be a non-ring structure such as a lug or hook for attaching to the corresponding connecting parts of the heavy equipment. Its shape can be flexibly adjusted according to the structure of the connecting parts on the heavy equipment, and is not specifically limited here.

[0046] In some embodiments, the number of lifting mechanisms 20 can be multiple, which can be spaced apart from each other and movably distributed at the top of the lifting frame 10.

[0047] By setting up multiple lifting mechanisms 20, the rated lifting force of the heavy equipment lifting device 1 can be increased to stabilize the lifting of heavy equipment. By setting them in a matrix distribution at the top of the lifting frame 10, they can be arranged around the outer contour of the heavy equipment, thereby facilitating the lifting of the heavy equipment.

[0048] By movably mounting the lifting mechanism 20 on the lifting frame 10, the heavy equipment lifting device 1 can lift heavy equipment of different sizes. For the lifting of each piece of heavy equipment, the position of the lifting mechanism 20 on the lifting frame 10 can be adjusted so that the tensioning cable 22 is vertically positioned after connecting to the heavy equipment, thereby improving the utilization rate of the lifting mechanism 20.

[0049] exist Figure 3In the illustrated embodiment, there are four hoisting mechanisms 20. The top wall 11 of the hoisting frame 10 may include a profile frame 111, two mounting platforms 112, and four movable frames 113. The profile frame 111 may be a rectangular frame formed by four steel sections connected end-to-end. The two mounting platforms 112 are arranged parallel and spaced apart, with each platform 112 connected at both ends to opposite sides of the profile frame 111. Two movable frames 113 are movably mounted on each mounting platform 112, and the hoisting mechanisms 20 are mounted on the movable frames 113, thereby enabling movement at the top of the hoisting frame 10.

[0050] The installation platform 112 can be composed of two parallel steel sections spaced apart, with a longitudinal gap 110 between them. The tensioning strand 22 of the hoisting mechanism 20 can extend into the hoisting space 100 through this gap 110. The movable frame 113 is movably mounted on the two steel sections of the installation platform 112, and has clearance holes (not shown in the figure) corresponding to the gap 110. The connecting end of the tensioning strand 22 of the hoisting mechanism 20, mounted on the movable frame 113, can extend into the hoisting space 100 sequentially through the clearance holes and the gap 110.

[0051] It is important to understand that the two steel sections of the mounting platform 112 can be provided with numerous parallel and spaced assembly holes, which are correspondingly provided on the movable frame 113. During the assembly process, based on the dimensions of the heavy equipment, the assembly holes on the steel sections are selected, and the movable frame 113 is connected to the movable frame 113 using bolts, thereby adjusting the position of the movable frame 113 on the mounting platform 112.

[0052] Of course, in some other optional embodiments, the installation platform 112 may also be provided with a guide rail structure, and the movable frame 113 may be provided with a corresponding movable structure. The movable structure is movably mounted on the guide rail structure to realize the movement of the movable frame 113 on the installation platform 112.

[0053] It should be understood that the moving structure and the guide rail structure can be guide grooves and guide bars, or guide rails and moving wheels, etc., and no specific limitation is made here.

[0054] In some embodiments, each lifting mechanism 20 may include multiple tension strands 22. The tension strands 22 may be steel wire ropes, and the tension strength of each tension strand 22 is about 15 tons. The tension strength of multiple tension strands 22 is superimposed to achieve the lifting of heavy equipment.

[0055] exist Figure 1In the illustrated embodiment, each lifting mechanism 20 may include 7 to 8 tension strands 22, thereby each lifting mechanism 20 can achieve a rated lifting force of up to 105 to 120 tons. The heavy equipment lifting device 1 is equipped with four lifting mechanisms 20, so the heavy equipment lifting device 1 can achieve a rated lifting force of 420 to 480 tons.

[0056] In some embodiments, when the lifting mechanism 20 is a tension jack, it can be a hydraulic jack. In this embodiment, the drive mechanism 30 can use an existing hydraulic module to drive the lifting mechanism 20 to achieve lifting. The drive mechanism 30 can be connected to multiple lifting mechanisms 20 via hydraulic lines to achieve drive control of multiple lifting mechanisms 20.

[0057] The drive mechanism 30 can be installed on the top wall 11 of the hoisting frame 10. By adding steel profiles to the outline frame 111 of the top wall 11, an installation position for the drive mechanism 30 can be constructed, thus enabling the drive mechanism 30 to be installed on the hoisting frame 10.

[0058] It should be understood that the current drive mechanism 30 may include multiple fluid-conducting pipelines, which are respectively connected to multiple lifting mechanisms 20. At the same time, the multiple pipelines can be interconnected, and by setting valves, the fluid can be supplied to the multiple lifting mechanisms 20 synchronously, thereby enabling the tensioning strands 22 of the multiple lifting mechanisms 20 to extend and retract synchronously, achieving stable lifting of heavy equipment.

[0059] Of course, when the lifting mechanism 20 uses an electric or pneumatic jack, the drive mechanism 30 can use an existing motor or pneumatic module, which will not be discussed in detail here.

[0060] This application also constructs a main equipment hoisting system for a gas-fired power plant, which can hoist main equipment such as steam turbines, gas turbines, gas turbine generators, and steam turbine generators within the gas-fired power plant. This main equipment hoisting system for the gas-fired power plant may include the heavy equipment hoisting device 1 from any of the foregoing embodiments.

[0061] In some embodiments, the main equipment hoisting system of the gas-fired power plant may further include a transfer platform (not shown) and at least one transfer drive mechanism. The transfer drive mechanism is disposed on the transfer platform and is used to drive the heavy equipment hoisting device 1 to move along the transfer platform, so as to realize the horizontal transfer of the main equipment.

[0062] The transfer platform can be defined as having a lifting space and a placement space. The heavy equipment lifting device 1 can be defined as having a lifting space 100. The size of the lifting space, the placement space, and the lifting space 100 can all accommodate the main equipment, so as to realize the lifting and installation of the main equipment by transferring the main equipment between several spaces.

[0063] Specifically, driven by the transfer drive mechanism, the heavy equipment hoisting device 1 can have a lifting position and a placement position on the transfer platform.

[0064] When the heavy equipment hoisting device 1 is in the lifting position on the transfer platform, the hoisting space 100 can be connected to the lifting space, and the hoisting space 100 is located above the lifting space. At this time, the hoisting mechanism 20 can move the main equipment back and forth vertically between the lifting space and the hoisting space 100.

[0065] When the heavy equipment hoisting device 1 is in the placement position on the transfer platform, the hoisting space 100 can be connected to the placement space, and the hoisting space 100 is located above the placement space. At this time, the hoisting mechanism 20 can hoist the main equipment back and forth vertically between the placement space and the hoisting space 100.

[0066] It is understood that the above embodiments only illustrate some implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that for those skilled in the art, without departing from the concept of this application, the above embodiments or technical features can be freely combined, and several modifications and improvements can be made. These all fall within the protection scope of this application, that is, the embodiments described "in some embodiments" can be freely combined with any of the embodiments above and below. Therefore, all equivalent transformations and modifications made within the scope of the claims of this application should fall within the coverage of the claims of this application.
