[0002] In the nuclear power sector, diesel generator sets are often used for emergency power supply. After a certain number of years of use, these generator sets need to be replaced. A generator set consists of a diesel engine and a generator, and each diesel engine and generator weighs over ten tons.

[0003] In actual applications, the generator set is usually installed on a foundation in the machine room, and there is often a large height difference between the foundation and the ground, which makes it difficult to move the generator set. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a generator set transport auxiliary tooling and transport method to solve the technical problem of difficulty in transporting the generator set.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] In a first aspect, a generator set transport auxiliary tooling is provided, wherein the generator set is installed on a foundation in a machine room, the foundation is arranged on the internal floor of the machine room, and the top surface of the foundation is higher than a preset value of the internal floor of the machine room, and the generator set transport auxiliary tooling includes a first leveling component, the first leveling component is used to be laid on the internal floor of the machine room, so that the height difference between the top surface of the foundation and the top surface of the first leveling component is less than a preset value, the area of ​​the first leveling component is larger than the area of ​​the projection of either the diesel engine or the generator on the internal floor of the machine room, and the first leveling component is arranged along the edge of the foundation and can extend to the door of the machine room.

[0007] The generator set transport auxiliary tooling provided in this application can utilize a first leveling assembly positioned along the edge of the foundation. This allows a transport truck to stably transition between the foundation and the first leveling assembly when transporting the diesel engine and generator, reducing the risk of the transport truck tipping over and easing the difficulty of transport. Furthermore, the first leveling assembly can extend to the engine room door, allowing the transport truck to be moved to the engine room door. Furthermore, the area of ​​the first leveling assembly is larger than the projected area of ​​either the diesel engine or the generator on the floor inside the engine room. This allows the transport truck to steer and deviate from the predetermined trajectory to a certain extent when transporting the diesel engine and generator, thus easing the difficulty of transport.

[0008] Therefore, the generator set transport auxiliary tooling provided in this application can reduce the difficulty of transport, thereby solving the technical problem of difficulty in transporting the generator set.

[0009] In some embodiments, the first leveling portion surrounds the foundation; or a groove is formed on one side of the first leveling component, and the groove can accommodate one end of the foundation.

[0010] In some embodiments, the generator set includes two diesel engines and a generator, the generator is located between the two diesel engines, the foundation includes a first part, a second part and a third part arranged in sequence, the two diesel engines are installed on the first part and the third part respectively, and the generator is installed on the second part. Compared with the second part and the third part, the first part is closer to the door of the machine room, and the first leveling assembly includes a first leveling part and a second leveling part connected to each other. The first leveling part is arranged along the edge of the foundation, and the second leveling part is located on the side of the first leveling part close to the door of the machine room and can extend to the The door of the machine room; the first leveling portion includes a first leveling sub-portion, a second leveling sub-portion and a third leveling sub-portion, the first leveling sub-portion is located on the side of the first part away from the second part, the second leveling sub-portion and the third leveling sub-portion are both located on the side of the first leveling sub-portion close to the first part, and are respectively located on opposite sides of the first part; compared with the second leveling sub-portion, the third leveling sub-portion is closer to the door of the machine room, and along the direction from the first part to the second part, the size of the third leveling sub-portion is larger than the size of the second leveling sub-portion, and / or the size of at least one of the second leveling sub-portion and the third leveling sub-portion is larger than or equal to the size of the first part.

[0011] In this way, the first leveling portion surrounds the foundation, allowing the transport vehicle to smoothly transition between the foundation and the first leveling assembly when transporting the diesel engine and generator, reducing the risk of the transport vehicle tipping over and easing the difficulty of transport. Furthermore, the transport vehicle can turn and deviate from the predetermined trajectory to a certain extent when transporting the diesel engine and generator off the foundation, further reducing the difficulty of transport.

[0013] This allows the use of a larger steel platform to be laid where the foundation pit is located within the machine room, preventing the nylon pads from being laid where the foundation pit is located. This prevents the nylon pads from warping when a truck travels over the pit. Furthermore, the nylon pads' small size simplifies their processing.

[0014] In some embodiments, the nylon pad is cast from monomer casting nylon (MC nylon); and / or, at least one nylon pad is provided with a notch that matches the edge of the foundation; and / or, the steel platform includes a frame, a second steel plate and a third steel plate, the second steel plate and the third steel plate are respectively fixed on both sides of the frame in the thickness direction, the third steel plate is located on the side of the frame close to the first steel plate, and is provided with a plurality of hollow grooves; and / or, the support frame includes a plurality of spaced support beams, the first steel plate is fixed above the support beams, the auxiliary tooling also includes a plurality of support legs, the support legs are arranged between the two support beams, and support the first steel plate, and the bottom of at least one support leg is provided with a avoidance groove for avoiding pipelines.

[0015] In this way, the nylon pad has the characteristics of high strength and light weight, strong pressure bearing capacity and easy transportation. The notch of the nylon pad can match the edge of the foundation, making it convenient to lay the nylon pad on the floor inside the machine room. The third steel plate is provided with multiple hollow grooves, which is conducive to welding the second steel plate to the frame and can reduce the weight of the third steel plate. The support legs support the first steel plate, which can increase the strength of the first steel plate and prevent the first steel plate from deforming.

[0016] In some embodiments, the auxiliary tooling also includes a second leveling component, which is at least used to be laid on the ground outside the machine room and is located at the door of the machine room. The height difference between the top surface of the second leveling component and the top surface of the first leveling component is less than or equal to a preset value.

[0017] In this way, the auxiliary tooling can reduce the height difference between the top surface of the second leveling assembly and the top surface of the first leveling assembly, so that the transport vehicle can be moved stably to the outside of the machine room.

Furthermore, by laying the second leveling assembly on the floor outside the machine room, ensuring that the height difference between the top surface of the second leveling assembly and the top surface of the first leveling assembly is less than or equal to a preset value, the transport truck can be stably moved outside the machine room.

[0062] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0065] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0066] In the nuclear power field, diesel generator sets are usually used for emergency power supply. After a certain number of years of use, the generator sets need to be replaced as a whole.

[0067] See also Figure 1 In the related art, a generator set (not shown in the figure) is suitable for being installed on a foundation 2 in a machine room 1. The foundation 2 is arranged on the internal ground 101 of the machine room, and the height difference between the top surface of the foundation 2 and the internal ground 101 of the machine room is greater than a preset value. The top surface of the foundation 2 is higher than the internal ground 101 of the machine room. Usually, the top surface of the foundation 2 is 130 mm or more higher than the internal ground 101 of the machine room. For example, the top surface of the foundation 2 is 130 mm higher than the internal ground 101 of the machine room. The generator set includes two diesel engines and a generator. The generator is located between the two diesel engines. The foundation 2 includes a first part 21, a second part 22 and a third part 23 arranged in sequence. The two diesel engines are respectively installed on the first part 21 and the third part 23, and the generator is installed on the second part 22. Compared with the second part 22 and the third part 23, the first part 21 is closer to the machine room door 102.

[0068] In related art, when replacing and transporting a generator set, the diesel engine mounted on the first section 21 is moved first, followed by the generator, and finally the diesel engine mounted on the third section 23. The process for moving both diesel engines and the generator is the same, so the diesel engine mounted on the first section 21 will be used as an example. During transport, the diesel engine must be lifted with a jack and then moved to its base using a transport truck.

[0069] The inventor found that there is a large height difference (greater than the preset value) between the internal floor 101 of the machine room where the generator set is located and the top surface of the foundation 2 used to place the generator set. When using a transport truck to transport the diesel engine from the foundation 2 to the internal floor 101 of the machine room, the transport truck is prone to tipping over, making transportation difficult.

[0070] To solve the above problems, an embodiment of the present application provides a generator set transport auxiliary tooling and a transport method.

[0071] Please also refer to Figure 1 and Figure 2The auxiliary tooling for transporting a generator set provided in an embodiment of the present application will now be described. This auxiliary tooling includes a first leveling assembly 3, which is laid on the floor 101 within the machine room, ensuring that the height difference between the top surface of the foundation 2 and the top surface of the first leveling assembly 3 is less than a preset value. This allows a transport truck to stably transition between the foundation 2 and the first leveling assembly 3 when transporting a diesel engine and generator, reducing the risk of the truck tipping over and simplifying the handling process.

[0072] For example, the height difference between the top surface of the first leveling component 3 and the top surface of the foundation 2 is less than or equal to the above-mentioned preset value. It is understandable that the above-mentioned preset value may be 10 mm.

[0073] The first leveling assembly 3 is arranged along the edge of the foundation 2 and can extend to the machine room door 102. The first leveling assembly 3 can be laid to the machine room door 102, so that the transport truck can smoothly transport the diesel engine and generator to the machine room door 102.

[0074] The first leveling assembly 3 is laid on the interior floor 101 of the machine room as follows: the first leveling assembly 3 includes a first leveling portion 301 and a second leveling portion 302. The first leveling portion 301 is positioned along the edge of the foundation 2, allowing a transport truck to smoothly move the diesel engine and generator from the foundation 2 to the first leveling assembly 3. The second leveling portion 302 is located on the side of the first leveling portion 301 near the machine room door 102. The second leveling portion 302 is connected to the first leveling portion 301 and is laid at least on the portion of the interior floor 101 between the foundation 2 and the machine room door 102, extending to the machine room door 102. Therefore, the transport truck can move stably on the first leveling assembly 3, thereby smoothly transporting the diesel engine and generator to the machine room door 102.

[0075] In addition, the area of ​​the first leveling component 3 is larger than the projected area of ​​either the diesel engine or the generator on the floor 101 inside the machine room. The transport vehicle can turn and deviate from the predetermined trajectory to a certain extent when transporting the diesel engine and the generator, which helps to reduce the difficulty of transportation.

[0076] Therefore, the generator set transport auxiliary tooling provided in this application can reduce the difficulty of transport, thereby solving the technical problem of difficulty in transporting the generator set.

[0077] In some embodiments, a groove 303 is formed on one side of the first leveling assembly 3, and one end of the base 2 can be accommodated in the groove 303, that is, the first leveling assembly 3 can semi-enclose the base 2. This allows the transport vehicle to move stably to the first leveling assembly 3 when moving toward the machine room door 102 or turning.

[0078] The end of the base 2 adapted to be accommodated in the groove 303 may be the end having the first portion 21 or the end having the third portion 23. In other words, at least a portion of the first portion 21 is located in the groove 303, or at least a portion of the third portion 23 is located in the groove 303.

[0079] Exemplarily, the first portion 21 is located within the groove 303. Specifically, the first leveling portion 301 includes a first leveling sub-portion 3011, a second leveling sub-portion 3012, and a third leveling sub-portion 3013. The first leveling sub-portion 3011 is located on the side of the first portion 21 away from the second portion 22, while the second leveling sub-portion 3012 and the third leveling sub-portion 3013 are located on the side of the first leveling sub-portion 3011 closer to the first portion 21. The second leveling sub-portion 3012 and the third leveling sub-portion 3013 are located on opposite sides of the first portion. In other words, the first leveling sub-portion 3011, the second leveling sub-portion 3012, and the third leveling sub-portion 3013 collectively form the groove 303.

[0080] It is understood that the first leveling portion 301 can semi-enclose the first portion 21, allowing the transport vehicle to stably move to the first leveling assembly 3 when moving toward the machine room door 102 or turning. In addition, compared to the second portion 22 and the third portion 23, the first portion 21 is closer to the machine room door 102. The first portion 21 is located in the groove 303, allowing the transport vehicle to move to the machine room door more quickly.

[0081] In this way, the transport vehicle can stably turn and deviate from the predetermined trajectory to a certain extent when transporting the diesel engine and the generator away from the foundation 2, thereby reducing the difficulty of transportation.

[0082] In some embodiments, the third leveling sub-section 3013 is closer to the engine room door 102 than the second leveling sub-section 3012. Along the direction from the first portion 21 to the second portion 22, the third leveling sub-section 3013 is larger than the second leveling sub-section 3012. This allows the transport vehicle to stably turn on the third leveling sub-section 3013 and deviate from the predetermined trajectory to a certain extent while transporting the diesel engine and generator off the foundation 2, thereby reducing the difficulty of transport.

[0083] In some embodiments, along the direction from the first portion 21 to the second portion 22, at least one of the second leveling sub-portion 3012 and the third leveling sub-portion 3013 has a size greater than or equal to that of the first portion 21. In this way, when a transport truck is transporting the diesel engine and generator off the foundation 2, the second leveling sub-portion 3012 and the third leveling sub-portion 3013 can provide stable support for the transport truck, preventing the transport truck from becoming suspended in the air.

[0084] In other embodiments, the first leveling portion 301 can also be arranged to surround the foundation 2, that is, the first leveling portion 301 extends along the edge of the foundation 2. In this way, the transport vehicle can move the diesel engine and the generator away from the foundation 2 from all directions. This embodiment does not limit this.

[0085] In addition, in order to make it more convenient for the transport vehicle to move in the machine room 1, the first leveling assembly 3 can cover the entire interior floor 101 of the machine room.

[0086] See also Figure 3 The inventors also discovered that a foundation pit (not shown) is provided on the interior floor 101 of the machine room. The interior floor 101 of the machine room includes a first floor and a second floor for laying the first leveling assembly 3, with the foundation pit located on the first floor. A support frame 5 is provided within the foundation pit, and a first steel plate 52 is provided on top of the support frame 5. The top surface of the first steel plate 52 is flush with the second floor of the interior floor 101 of the machine room. When a transport truck moves to the first steel plate 52, the first steel plate 52 is easily deformed, and the first leveling assembly 3 is easily tilted, causing the transport truck to tip over.

[0087] To address the above issues, in some embodiments, the first leveling assembly 3 includes at least one steel platform 32 and a plurality of nylon pads 31. The steel platform 32 is used to be laid on the top surface of the first steel plate 52, and the nylon pads 31 are used to be laid on the second floor of the interior floor 101 of the machine room. The area of ​​the first steel plate 52 is larger than the area of ​​the nylon pads 31.

[0088] The auxiliary tooling provided in the embodiments of the present application utilizes a larger steel platform 32, which is laid on the first surface of the machine room interior floor 101, where the foundation pit is located, to prevent the nylon pad 31 from being laid on the first surface of the machine room interior floor 1. The high strength of the steel platform 32 prevents deformation of the first steel plate 52 when the transport vehicle travels over the location with the foundation pit, and also prevents the nylon pad 31 from tilting. Furthermore, the small area of ​​the nylon pad 31 reduces the difficulty of machining the nylon pad 31.

[0089] It is understandable that the nylon pad 31 is cast from monomer casting nylon (MC nylon), so that the nylon pad 31 has the characteristics of high strength and light weight, strong pressure bearing capacity and convenient transportation.

[0090] It should be noted that, in the first leveling portion 301 , the first leveling sub-portion 3011 includes a steel platform 32 , the second leveling sub-portion 3012 includes multiple nylon pads 31 , the third leveling sub-portion 3013 includes multiple nylon pads 31 , and the second leveling portion 302 includes multiple nylon pads 31 .

[0091] Please also refer to Figure 4 and Figure 5In some embodiments, the first leveling assembly 3 further includes an ear plate 33, which can be connected to two adjacent nylon pads 31 via a connector. The nylon pads 31 have a plurality of first connecting holes 311 defined on their sides, and the ear plates 33 have a plurality of second connecting holes 331 defined on their sides. The connector passes through the first connecting holes 311 and the second connecting holes 331, thereby securely connecting the nylon pads 31 and the ear plates 33.

[0092] The connecting member can be a threaded connecting member such as a screw or bolt, and correspondingly, the first connecting hole 311 and the second connecting member hole are threaded holes, and at least the first connecting hole 311 is a threaded hole. Of course, the connecting member can also be other connecting members such as rivets and pins that can fix the nylon pad 31 and the ear plate 33.

[0093] It can be understood that two adjacent nylon pads 31 are connected by the ear plate 33, so that the nylon pads 31 can restrict each other, which can help prevent the nylon pads 31 from warping.

[0094] Please also refer to Figure 1 and Figure 6 In some embodiments, at least one nylon pad 31 is provided with a notch 312 that matches the edge of the foundation 2. The notch 312 of the nylon pad 31 can match the edge of the first portion 21 of the foundation 2, making it easier to lay the nylon pad 31 on the floor 101 inside the machine room.

[0095] The inventors also discovered that the foundation 2 has a shock-absorbing spring at the bottom and has gaps around it. When the entire generator set is removed from the foundation 2, the foundation 2 rises a certain distance, easily lifting the nylon pad 31 and causing it to tilt. For example, the foundation 2 rises by 15 mm.

[0096] It is understandable that there is a gap between the nylon pad 31 and the side of the first portion 21 of the foundation 2, so that the nylon pad 31 avoids the dynamic and static gaps around the foundation 2. In this way, the nylon pad 31 will not tilt.

[0097] Please also refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In some embodiments, the steel platform 32 includes a frame 323, a second steel plate 321 and a third steel plate 322, and the second steel plate 321 and the third steel plate 322 are respectively fixed to the frame 323 in the thickness direction (such as Figure 6 On both sides of the frame 323 (in the Z direction), the third steel plate 322 is located on one side of the frame 323 close to the first steel plate 52 and is provided with a plurality of hollow grooves 3221.

[0098] It is understood that the steel platform 32 is made by welding, and the second steel plate 321 is first welded to the frame 323. During welding, it is not affected by the third steel plate 322, making welding convenient. However, when the third steel plate 322 is welded, the second steel plate 321 is already welded to the frame 323, and the second steel plate 321 will affect the welding of the third steel plate 322. In the embodiment of the present application, the third steel plate 322 is provided with a plurality of hollow grooves 3221, so that the third steel plate 322 can be welded to the frame 323 through the hollow grooves 3221, thereby facilitating the welding of the second steel plate 321 to the frame 323. In addition, the provision of hollow grooves 3221 on the third steel plate 322 can reduce the weight of the third steel plate 322, thereby reducing the overall weight of the steel platform 32, and facilitating transportation and handling.

[0099] The frame 323 includes a plurality of square steel tubes 3231 that are sequentially connected. The plurality of square steel tubes 3231 are connected along the length direction of the second steel plate 321 (eg Figure 6 The plurality of hollow grooves 3221 on the third steel plate 322 are also arranged in sequence along the length of the second steel plate 321, with each square steel tube 3231 corresponding to at least one hollow groove 3221. This allows the square steel tube 3231 to be welded to the third steel plate 322 through the hollow grooves 3221.

[0100] In some embodiments, the steel platform 32 further includes a plurality of threaded posts 324. The second steel plate 321 is further provided with a plurality of spaced-apart through-holes 3211. The through-holes 3211 correspond one-to-one with the threaded posts 324. The threaded posts 324 are located between the second steel plate 321 and the third steel plate 322 and are welded to the second steel plate 321. The threaded posts 324 are provided with threaded connection holes 3241, which are coaxial with the through-holes 3211 of the second steel plate 321. The threaded posts 324 can be connected to lifting rings or other lifting or transportation components provided through the through-holes 3211 and the threaded connection holes 3241, thereby facilitating transportation of the steel platform 32.

[0101] Among them, at least two through holes 3211 are along the length direction of the square steel tube 3231 (such as Figure 6 The length of the corresponding square steel tube 3231 is less than the width of the second steel plate 321, so that the square steel tube 3231 avoids the through hole 3211 and the threaded column 324, thereby forming an installation space 3201 for accommodating the threaded column 324 between the second steel plate 321 and the third steel plate 322.

[0102] Please also refer to Figure 3 and Figure 11The support frame 5 includes a plurality of spaced support beams 51, and a first steel plate 52 is fixed above the support beams 51. The auxiliary tooling provided in the embodiment of the present application also includes a plurality of support legs 6, which are arranged between two support beams 51 and support the first steel plate 52. The auxiliary tooling provided in the embodiment of the present application uses the support legs 6 to support the first steel plate 52, which can improve the strength of the first steel plate 52 and prevent deformation of the first steel plate 52.

[0103] Among them, the support leg 6 includes a support body 61, a first support plate 62 and a second support plate 63. The first support plate 62 is fixed on the top of the support body 61 and is used to contact the first steel plate 52. The second support plate 63 is fixed on the bottom of the support body 61 and is used to contact the ground of the foundation pit.

[0104] The inventors also discovered that pipelines are provided in the foundation pit. It is understood that the pipelines are pipelines for supplying electricity and water to the machine room 1, electrical wires, communication lines, etc. The support legs 6 are likely to crush the pipelines in the foundation pit.

[0105] See also Figure 12 The bottom of at least one supporting leg 6 of the auxiliary tooling provided in the embodiment of the present application is provided with an avoidance groove 64 for avoiding pipelines. The avoidance groove 64 can avoid the pipelines and prevent the supporting leg 6 from causing damage to the pipelines.

[0106] Please continue reading Figure 2 In some embodiments, the auxiliary tooling further includes a second leveling component 4, which is at least used to be laid on the external ground 103 of the machine room and is located at the door 102 of the machine room.

The first sleepers 41 are laid out in order from high to low on the steps, and the number of first sleepers 41 gradually increases, so that the top surface of the highest first sleeper 41 is flush with the top surface of the nylon pad 31. The top surface of the highest first sleeper 41 is the highest surface of the at least one first sleeper 41, and the top surface of the nylon pad 31 is the top surface of the first leveling assembly 3.

[0110] The second leveling assembly 4 includes a plurality of second sleepers 42, a plurality of third sleepers 43 and a plurality of fourth steel plates 44. The second sleepers 42 are used to be laid on the ground 103 outside the machine room, the third sleepers 43 are used to be laid above the second sleepers 42, and the fourth steel plates 44 are used to be laid above the third sleepers 43. The length direction of the first sleeper 41 is perpendicular to the length direction of the second sleeper 42. Two adjacent fourth steel plates 44 are welded, wherein the top surface of the fourth steel plate 44 is flush with the top surface of the highest first sleeper 41.

[0111] In this way, the second leveling assembly 4 can use the first sleeper 41 to level the step at the machine room door 102. The second leveling assembly 4 lays two layers of sleepers (second sleepers 42 and third sleepers 43) on the ground 103 outside the machine room to improve structural stability. The second leveling assembly 4 also lays a fourth steel plate 44 above the sleepers to further stabilize the structure.
