Description

Technical Field

[0001] This invention belongs to the nuclear industry field, specifically relating to the field of equipment hoisting and installation. Background Technology

[0002] The condenser is one of the core pieces of equipment in the turbine building of the conventional island of a nuclear power plant, and the installation of the condenser shell is one of the most challenging aspects of the condenser installation work in the conventional island of a nuclear power plant. Condenser shells are mostly supplied in modular form, usually divided into four modules. Each shell module is large in size and heavy in weight, making the introduction and placement of the modules difficult and technically demanding.

[0003] Reference Figure 1 As shown, the hoisting and introduction of the existing condenser shell module 200 mainly utilizes the balance beam structure, with the crawler crane 101, truck crane hook 102, and gantry crane hook 103 assisting in hoisting the condenser shell module 200. Then, the condenser shell module 200 is positioned by using two gantry cranes in the conventional island turbine plant to switch hooks.

[0004] However, the aforementioned hoisting technologies have significant limitations in the layout and design of indoor overhead cranes and plant structures, and are insufficient to cover all conventional island turbine buildings in current nuclear power plants. Not only does the plant require multiple overhead cranes and corresponding track structures, but the hook-changing process is also quite complex. Furthermore, the condenser shell modules are heavy, with a single module weighing approximately 105 tons, posing a potential safety hazard. Chinese patent document CN212271646 discloses an installation device for condenser shells, but the use of a propulsion method can easily lead to uneven force distribution and trajectory deviation. Summary of the Invention

[0005] One object of the present invention is to provide a condenser shell module introduction device that can safely and practically realize the towing of large condenser shell modules.

[0006] A condenser shell module introduction device, designed to achieve the aforementioned objectives, is used to introduce the condenser shell module from outside the plant into the plant. This device includes a support frame, a transport rail, a tracked heavy-duty transporter, and a traction device. The transport rail is fixedly mounted on the support frame; the tracked heavy-duty transporter carries the condenser shell module and is capable of moving along the transport rail; the traction device applies a pulling force to the condenser shell module and / or the tracked heavy-duty transporter, and the traction device includes a manual hoist or an electric hoist.

[0007] In one or more embodiments, the traction device further includes a traction lug, which is fixedly mounted on the towing rail or an external fastener, and the manual hoist or the electric hoist is connected to the traction lug.

[0008] In one or more embodiments, the tracked heavy object transporter includes a fixed part and a moving part, the moving part including a track and rollers, and the fixed part disposed above the moving part for fixing the condenser shell module.

[0009] In one or more embodiments, the transport track includes a track beam and a first baffle and a second baffle located on both sides of the track beam. The track beam forms a track groove defined by the first baffle and the second baffle, and the track groove is used for the movement of the tracked heavy load transfer device.

[0010] In one or more embodiments, the support frame includes locking casters.

[0011] In one or more embodiments, the condenser shell module introduction device includes multiple rows of the towing rails and multiple tracked heavy load transfer devices, the multiple rows of the towing rails being arranged in parallel on the support frame, and each row of the towing rails including multiple tracked heavy load transfer devices.

[0012] In one or more embodiments, the support frame includes a first support frame and a second support frame, the extension directions of the first support frame and the second support frame intersect each other, the transport track includes a first transport track, a second transport track and an arc-shaped connecting portion connecting the first transport track and the second transport track, the first transport track and the second transport track are respectively disposed on the first support frame and the second support frame, and the tracked heavy object transporter is capable of continuous travel in the first transport track, the second transport track and the arc-shaped connecting portion.

[0013] Another object of the present invention is a method for introducing a condenser shell module, which uses the aforementioned condenser shell module introducing device. The method includes the following steps: assembling the condenser shell module introducing device and moving the support frame of the condenser shell module introducing device to the position to be towed; hoisting the condenser shell module onto a tracked heavy object transfer device on a towing track using external lifting equipment; fixing a traction device to the condenser shell module and / or the tracked heavy object transfer device; pulling the traction device to drag the condenser shell module to a designated position on the towing track; and hoisting the condenser shell module to the installation position using an indoor crane in the plant.

[0014] In one or more embodiments, when the traction device is pulled, it is checked whether the actual towing trajectory of the condenser shell module is parallel to the towing track, and adjustments are made in a timely manner to keep the actual towing trajectory of the condenser shell module parallel to the towing track.

[0015] In one or more embodiments, when pulling the traction device, it is checked whether the pulling direction of the traction device is parallel to the center line of the towing track, and adjustments are made in a timely manner to keep the pulling direction of the traction device parallel to the center line of the towing track.

[0016] The aforementioned condenser shell module introduction device addresses the design of existing nuclear power plants where the conventional island turbine building structure only has a single overhead crane. By setting up support frames and transport tracks, a moving track is formed to introduce the condenser shell module from outside the building into the interior. With the cooperation of a traction device and a tracked heavy-duty transporter, the effective towing and movement of heavy objects is safely and practically achieved, and the operation is simple and convenient. Using a manual or electric hoist, the starting speed and instantaneous movement speed are relatively slow, which provides stable pulling force while avoiding excessive impact on the overall device, ensuring the safety and stability of the pulling process.

[0017] The device has a simple overall structure, will not delay the main construction progress of the conventional island of the nuclear power plant, and will not affect heavy objects such as the nuclear construction condenser during the movement, nor will it pose a safety risk to the installation and construction of heavy objects.

[0053] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0054] It should be noted that these and other accompanying drawings are merely examples and are not drawn to scale, and should not be construed as limiting the scope of protection of the present invention.

[0055] It should be noted that the use of terms such as "first" and "second" to define components in the following description is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0056] In nuclear power plant construction, the difficulty in introducing the condenser shell module lies in the fact that the low-pressure cylinder inlet above the foundation is smaller than the module itself, and the shell module is the heaviest module in the condenser, with a single module weighing approximately 105 tons, presenting numerous challenges. The conventional island turbine building structure and crane layout of nuclear power plants are relatively simple, with dual main cranes typically arranged on the same track level, which cannot be easily altered or added to. Therefore, it is difficult to use a crane-coupler changing method to ensure the safe and smooth placement of the condenser shell module.

[0057] The condenser shell module introduction device disclosed herein, based on practicality, safety, and economy, changes the traditional method of introducing heavy objects, reduces the safety risks brought by this special design to the installation and construction of the conventional island condenser, and ensures the main construction progress of the conventional island of the nuclear power plant.

[0058] Reference Figure 2 and Figure 3 As shown, the condenser shell module introduction device includes a support frame 40, a towing rail 30, a tracked heavy load transfer device 10, and a traction device 20. The towing rail 30 is fixedly mounted on the support frame 40. The tracked heavy load transfer device 10 is used to carry the condenser shell module 200 and can move on the towing rail 30. The traction device 20 is used to apply a pulling force to the condenser shell module 200 and / or the tracked heavy load transfer device 10. The traction device 20 includes a manual hoist or an electric hoist.

[0059] The aforementioned device can safely bring the condenser shell module 200 from outside the plant 105 into the plant. By setting up a transport track 30 extending from the outside to the inside of the plant 105, and by using a tracked heavy load transfer device 10, the movement of the condenser shell module 200 can be achieved safely and practically.

[0060] The condenser shell module 200 outside the plant 105 is hoisted onto the tracked heavy object transfer device 10 on the transport rail 30 using external lifting equipment, such as a common crawler crane 101 or a crane hook.

[0061] The traction device 20 pulls the condenser shell module 200 to the designated position according to the arrangement of the transport track 30. With the force applied by the manual hoist or electric hoist, its starting speed is relatively slow and the instantaneous movement speed is slow. This can provide a stable pulling force while avoiding excessive impact on the overall device, ensuring the safety and stability of the pulling process.

[0062] At this point, the condenser shell module 200 enters the plant 105 from outside, for example, by being directly towed to the area below the indoor trolley 300. In conventional island turbine plant buildings, the indoor trolley 300 mostly moves on indoor tracks 301 and can pull objects up and down or move left and right. However, the trolley 300's range of motion is limited, moving only within the trolley movement space 307 formed by the indoor tracks 301.

[0063] After the condenser shell module 200 is placed within the overhead crane's operating space 307, the condenser shell module 200 can be moved further using the indoor overhead crane 300 until the heavy object is hoisted to the installation position. This method solves the problem of design limitations in moving heavy objects to indoor plant buildings, eliminates the need for multiple overhead cranes and hook changes, and is simple, safe, and practical to operate.

[0064] The following continues the description of the components of the condenser shell module introduction device. Specific terms are used in the following description to describe embodiments of this application. For example, "one embodiment" and / or "some embodiments" refer to a particular feature, structure, or characteristic related to at least one embodiment of this application. It should be emphasized and noted that references to "one embodiment," "an embodiment," or "an alternative embodiment" in different locations throughout this specification do not necessarily refer to the same embodiment. Furthermore, certain features, structures, or characteristics in one or more embodiments of this application can be appropriately combined.

[0065] Reference Figure 2 As shown, in one embodiment, the traction device 20 further includes a traction lug 201, which is fixedly mounted on the external fixing member 50, and a manual hoist or an electric hoist is connected to the traction lug 201.

[0066] Reference Figure 3 As shown, in one embodiment, the traction device 20 further includes a traction lug 201, which is fixedly mounted on the transport rail 30. A manual hoist or an electric hoist is connected to the traction lug 201. The traction lug 201 may be directly welded to the rail groove 313, for example.

[0067] If the structure of factory building 105 is solid, then adopt... Figure 2 As shown in the example, external fasteners can be selected from load-bearing components such as structural columns of the factory building, other retaining walls, or embedded plates. If the stress on factory building 105 is considered excessive, then... Figure 3 As shown in the example, the traction lug 201 is welded to the end of the towing rail 30, and the force point is directly provided through the towing rail 30.

[0068] Furthermore, in one embodiment, reference is made to... Figure 3 , Figure 9 and Figure 10 As shown, the towing track 30 includes a track beam 311 and a first baffle 312 and a second baffle 314 located on both sides of the track beam 311. The track beam 311 forms a track groove 313 under the constraint of the first baffle 312 and the second baffle 314. The track groove 313 is used for the movement of the tracked heavy-duty transporter 10. The track groove 313 prevents the tracked heavy-duty transporter 10 from slipping out of the track groove during traction of the condenser shell module, thus preventing a potential hazard.

[0069] Continue to refer to Figure 3 As shown, the traction device 20 also includes a rope 202 and a shackle. One end of the rope 202 is used to fix the condenser shell module 200 or the tracked heavy load transfer device 10. The electric hoist or manual hoist is connected to the traction lug 201 via the shackle and the rope 202. The load capacity of the traction lug 201 is preferably 5 tons or more, and the capacity of the manual hoist or electric hoist is preferably 5 tons or more to provide sufficient load-bearing strength.

[0070] Using electric or manual hoists as the traction power source, their starting speed is relatively slow and their instantaneous movement speed is slow. This can provide stable traction force while avoiding excessive impact on the overall equipment, thus ensuring the stability of the plant 105 and the overall equipment.

[0071] In addition, by using the traction device 20 to directly fix the rope 202 to the center or center of gravity of the condenser shell module 200 or the tracked heavy object transfer device 10, the balance and stability of the pulling force during the traction process can be ensured. Furthermore, by adjusting the overlap between the rope 202 and the moving path of the condenser shell module 200 at any time, the synchronization between the two can be ensured, effectively preventing the traction path from deviating, thereby ensuring the safety of the traction process.

[0072] Continue to refer to Figure 4 As shown, in one embodiment, the tracked heavy load transfer device 10 includes a fixed part 11 and a moving part 13. The moving part 13 includes a track 131 and rollers 132. The fixed part 11 is disposed above the moving part 13 and is used to fix the condenser shell module 200. The force driving the rollers 132 to rotate is the pulling force of the traction device 20.

[0073] On the one hand, the tracked heavy load transfer device 10 can provide sufficient load-bearing capacity to ensure the load-bearing strength for the condenser shell module 200, which weighs only one hundred tons; on the other hand, the rolling friction coefficient of the tracked heavy load transfer device 10 is very small, so the traction force can be further reduced, thereby reducing the cost and complexity of the device.

[0074] Reference Figure 5 As shown, in one embodiment, the tracked heavy load transfer device 10 further includes a side plate 136 and a roller track 137, the roller track 137 being fixed by the side plate 136, and the drive roller 132 rotating around the roller track 137. The fixing part 11 is used to fix the condenser shell module 200, for example, the condenser shell module 200 can be fixed above the fixing part 11 by ropes or the like.

[0075] Embodiments of the tracked heavy object transporter 10 include, but are not limited to, those of other types. Figure 4 and Figure 5 Examples are provided. Those skilled in the art will understand that any heavy-duty transporter with a roller track structure can be applied to this disclosure without exceeding its scope.

[0076] Continue to refer to Figure 6 As shown in one embodiment 2, the condenser shell introduction device includes multiple rows of towing tracks 30 and multiple tracked heavy load transfer devices 10. The multiple rows of towing tracks 30 are arranged in parallel on the support frame 40, and each row of towing tracks 30 includes multiple tracked heavy load transfer devices 10.

[0077] Multiple tracked heavy-duty transporters 10 provide sufficient support strength for the condenser shell module 200. The tracked heavy-duty transporters 10 are evenly distributed according to the weight and structure of the shell module, and the number of them is determined according to the load. Setting up multiple rows of towing tracks 30 allows two condenser shell modules 200 to be towed simultaneously, improving efficiency.

[0078] The tracked heavy-duty transporter 10 requires a stable track with strong load-bearing capacity. In one embodiment, the columns and beams of the support frame 40 are made of HW250×250×9×14 or larger steel. The columns and beams are connected by bolts or welding through connecting plates. The diagonal braces are made of double-span HW150×150×7×10 or larger steel. The bottom of the columns is fixed to the foundation with chemical bolts to improve load-bearing strength. The track beam 311 is made of HN400×200 or larger H-beams, installed and welded parallel to the support frame 10 to improve support strength and provide a flat and sturdy track for the tracked heavy-duty transporter 10.

[0079] In another embodiment, the support frame 40 includes locking casters. After use, unlocking the locking casters allows the mobile support frame 40 to be moved to another location or stored, making operation simple and convenient. The locking casters should be made of a material with strong load-bearing capacity, and multiple casters should be provided under the support frame 40 to provide sufficient load-bearing capacity.

[0080] In one embodiment, the support frame 40 includes a first support frame and a second support frame, the extension directions of the first support frame and the second support frame intersect each other, the transport track 30 includes a first transport track, a second transport track and an arc-shaped connecting portion connecting the first transport track and the second transport track, the first transport track and the second transport track are respectively disposed on the first support frame and the second support frame, and the tracked heavy object transporter 10 can travel continuously in the first transport track, the second transport track and the arc-shaped connecting portion.

[0081] Setting up a first and second transport track with an arc-shaped connection allows for direct reversal of the condenser shell module 200. However, during the reversal process, an auxiliary traction device needs to be installed on the outside of the curve to achieve segmented traction and ensure traction safety and stability.

[0082] In addition, to ensure transport safety, in one embodiment, the transport track 30 also includes a limiting component (not shown in the figure). The limiting component is located at one end of the transport track 30 and is arranged perpendicular to the track extension direction. It is used to limit the movement range of the heavy object transferor 10 on the transport track 30, so as to prevent the heavy object transferor 10 from moving too much during the pulling process and causing the condenser shell module 200 to exceed the predetermined movement range.

[0083] Based on the description of the condenser shell introduction device, a condenser shell introduction method can also be understood. This method uses the condenser shell introduction device and specifically includes the following steps.

[0084] Assemble the condenser shell introduction device and move the support frame 40 of the condenser shell introduction device to the position to be towed; hoist the condenser shell module 200 onto the tracked heavy object transfer device 10 of the towing track 30 using external lifting equipment; fix the traction device 20 to the condenser shell module 200 and / or the tracked heavy object transfer device 10; pull the traction device 20 to drag the condenser shell module 200 to the designated position on the towing track 30; hoist the condenser shell module 200 to the installation position using the indoor crane in the plant.

[0085] The following is combined with Figure 7 and Figure 8 The method of introducing the condenser shell is explained.

[0086] (1) Preparation and setup stage: Install the support frame 40 and the towing rail 30. Place the tracked heavy load transfer device 10 on the towing rail 30. Connect the electric hoist or manual hoist and the rope 202 to the traction lug 201 through shackles. Assemble the condenser shell introduction device and move it to a suitable position, ensuring that the axis of each tracked heavy load transfer device 10 is parallel to the axis of the towing rail 30.

[0087] (2) Lifting stage: The condenser shell module 200 is lifted onto the heavy object transfer device 10 of the transport track 30 by external lifting equipment. For example, the condenser shell module 200 is lifted into place onto the heavy object transfer device 10 of the transport track 30 by an external crane.

[0088] (3) Traction stage: Connect one end of the pre-arranged traction device 20 to the center of the condenser shell module 200 or the center of the tracked heavy object transfer device 10, slowly operate the traction device 20, and after it is tightened by force, check and adjust the traction device 20 to be parallel to the center line of the towing track 30.

[0089] (4) Traction and transport stage: Pull the traction device 20 to drag the condenser shell module 200 on the transport track 30 to the designated position. The transport module moves a certain distance along the track, and checks whether the actual transport trajectory of the module is parallel to the track. If necessary, make appropriate adjustments to ensure that the module is parallel to the transport track 30. After confirming that the transport track 30 is stable and reliable multiple times, use the traction device 20 to horizontally transport the condenser shell module 200 to the upper part of the hot well.

[0090] For example in Figure 7 In the process, the traction device 20 is slowly operated to tow the condenser shell module 200 a certain distance along the track to position 200'. The actual towing trajectory of the condenser shell module 200 is checked in real time to ensure it is parallel to the track. If necessary, appropriate adjustments are made to ensure the condenser shell module 200 remains parallel to the towing track 30. After confirming the towing track is stable and reliable, the forward-moving traction device 20' is used to horizontally tow 200' to the upper part of the hot well.

[0091] (5) Heavy object hoisting and positioning stage: The condenser shell module 200' is hoisted to the installation position and positioned using an indoor overhead crane 300, as shown in the attached figure. Figure 6 The hoisting process was completed at the location of the condenser shell module 200 shown.

[0092] In one embodiment, when the traction device 20 is pulled, it is checked whether the actual towing trajectory of the condenser shell module 200 is parallel to the towing track 30, and adjustments are made in a timely manner to ensure that the actual towing trajectory of the condenser shell module 200 remains parallel to the towing track 30. By adjusting the actual towing trajectory of the condenser shell module 200 in a timely manner, it is ensured that the condenser shell module 200 will not deviate from the transfer track, thus guaranteeing safety during the towing phase.

[0093] In one embodiment, when pulling the traction device 20, it is checked whether the pulling direction of the traction device 20 is parallel to the center line of the transport track 30, and adjustments are made in a timely manner to ensure that the pulling direction of the traction device 20 remains parallel to the center line of the transport track 30. By maintaining the parallelism between the pulling direction of the traction device 20 and the center line of the transport track 30, the force direction of the condenser shell module 200 is always parallel to the center line of the transport track 30, effectively preventing deviation of the traction path, thereby ensuring the safety of the pulling process and ensuring the uniformity and stability of the pulling force.

[0094] The aforementioned method for introducing the condenser shell addresses the technical challenge of safely and smoothly positioning the condenser shell modules, which are designed with the same track layer and cannot be achieved using a crane-coupler swapping system. From a practical and safety perspective, it changes the traditional method that requires the use of a balance beam and two cranes in the conventional island turbine building for coupler swapping. By setting up support frames and transport tracks, a moving track is created for the condenser shell modules to be introduced from outside the building into the building. With the cooperation of a traction device and a tracked heavy-duty transporter, the effective towing and movement of heavy objects is safely and practically achieved. This overcomes the limitations of the aforementioned technology, significantly reduces the safety risks posed by this special design to the installation and construction of the conventional island condenser, ensures the main construction progress of the nuclear power plant's conventional island, and effectively simplifies the traditional operation process, saves resources, and improves transportation efficiency.
