[0043] The application will be further described below in combination with the drawings and examples.

[0044] The in-pile component transportation and lifting method comprises the following steps:

[0045] S1, a support tool is prepared, as shown in the figure, comprising a horizontal bracket 1, one end of the horizontal bracket 1 is provided with a detachable lifting bracket 2, the lifting bracket 2 is perpendicular to the horizontal bracket 1, the other end of the horizontal bracket 1 is connected with a vertical end support 3 through a 1 / 4 circular connecting plate 4, and the outer wall of the connecting plate 4 is provided with a detachable support seat 5; a positioning assembly is arranged on the horizontal bracket 1. Figures 1 to 4

[0046] The horizontal bracket 1 is used for supporting and positioning the in-pile component during transportation, and the positioning assembly is used for fixing the in-pile component on the horizontal bracket 1 to prevent the in-pile component from shaking during transportation. During transportation, the lifting bracket 2 and the end support 3 are located at both ends of the in-pile component, which plays an auxiliary positioning role and improves the stability and safety of the in-pile component. The horizontal bracket 1 can be welded from various existing steel profiles or connected into a frame structure through bolts, which has sufficient carrying capacity. After the in-pile component is transported to the installation site, the lifting bracket 2 is used to be connected with the lifting equipment, and the entire support tool can be lifted through the lifting bracket 2, so as to adjust the position of the tool and the in-pile component. The lower end of the outer wall of the connecting plate 4 is tangent to the lower surface of the horizontal bracket 1, and the upper end of the outer wall of the connecting plate 4 is tangent to the outer side surface of the end support 3.

[0047] S2, the in-pile component is hoisted onto the horizontal bracket 1, and the in-pile component is fixed horizontally on the horizontal bracket 1 through the positioning assembly.

[0048] ​In the workshop processing, the in-pile component is in a horizontal state, and the in-pile component itself is provided with a lifting lug for assisting lifting, so that the process of lifting and transporting the in-pile component to the horizontal bracket 1 does not have high difficulty, and the same, directly lifting and transporting the support tool in a horizontal state also does not have high difficulty. The lifting process with high difficulty is to change the position state of the in-pile component, that is, to adjust the in-pile component from a horizontal state to a vertical state.

[0049] S3, the support tool together with the in-pile component is transported to the installation site by the transport vehicle.

[0050] The transport vehicle can be a large truck, and the support tool together with the in-pile component is lifted and transported to the transport vehicle, and then the support tool together with the in-pile component is transported to the installation site of the nuclear power station by the transport vehicle. During installation, the support tool together with the in-pile component can be lifted and transported to the ground, and then the in-pile component is adjusted from a horizontal state to a vertical state.

[0051] S4, the lifting device is connected with the lifting frame 2, the lifting device pulls the lifting frame 2 to move upward, so that the whole support tool rotates upward, and in the rotating process, the connecting plate 4 supports the whole support tool, until the support tool rotates to a vertical state, and the in-pile component falls on the end support 3.

[0052] The lifting frame 2 is provided with a lifting rod 10, which can be one or two, and the lifting device can be connected with the lifting rod 10, so as to pull the lifting frame 2 to move upward through the lifting rod 10, and the lifting frame 2 drives the whole support tool together with the in-pile component to rotate. In the rotating process of the support tool, the connecting plate 4 supports the whole support tool, and since the connecting plate 4 is in the shape of 1 / 4 circle, the connecting plate 4 can play a good guiding role, so as to ensure that the support tool rotates smoothly and stably, reduce the adjustment difficulty, and improve the safety.

[0053] In the rotating process of the support tool, the in-pile component is always in the support tool and is kept stable through the positioning assembly, so as to prevent the in-pile component from rolling and other difficult-to-control movements.

[0054] The application adjusts the position of the cuboid-shaped support tool, instead of directly adjusting the position of the cylindrical in-pile component, so that the cuboid-shaped support tool has better stability and will not roll and have other difficult-to-control movements, thereby reducing the lifting difficulty.

[0055] S5, the support seat 5 is installed to the outer wall of the connecting plate 4.

[0056] After the support tool is adjusted to the vertical state, the end support 3 supports the whole support tool, since the size of the end support 3 is small and the height of the support tool is large, there is a gap below the arc-shaped connecting plate 4, which cannot contact the support surface, so that the stability of the support tool is poor. In order to improve the stability of the support tool, the support seat 5 is installed on the lower surface of the connecting plate 4, the support seat 5 fills the gap between the connecting plate 4 and the support surface, and the end support 3 supports the support tool at the same time, so that the stability of the support tool can be improved, and the support tool can be prevented from falling over.

[0057] S6, the lifting frame 2 is removed, the fixing of the in-core component is released, the in-core component is moved upward by the lifting device, so that the in-core component is separated from the support tool, and the in-core component is lifted into the reactor.

[0058] The lifting frame 2 can be connected to the horizontal bracket 1 through a plurality of bolts, the in-core component is supported by the end support 3 after the support tool is adjusted to the vertical state, the lifting frame 2 is removed, and the fixing of the positioning assembly to the in-core component is released, so that the in-core component is no longer constrained by the support tool, at this time, the lifting device can be connected to the upper end of the in-core component, the in-core component is vertically moved upward by the lifting device, so that the in-core component is separated from the support tool, then the in-core component is lifted to above the reactor, and the in-core component is vertically lowered into the reactor.

[0059] In the application, the positioning assembly can adopt various existing mechanisms capable of fixing the cylindrical parts, specifically, the positioning assembly comprises a plurality of arc-shaped pads 6, the pads 6 are fixedly installed on the horizontal bracket 1, the upper surface of the pad 6 is in a circular arc shape, and the diameter of the upper surface of the pad 6 is the same as the outer diameter of the in-core component, so that the upper surface of the pad 6 can be attached to the outer wall of the in-core component. The pad 6 can be two, which support the two ends of the in-core component. A steel wire hoop 7 is arranged above the pad 6, the two ends of the steel wire hoop 7 are connected to the horizontal bracket 1, and the steel wire hoop 7 and the pad 6 form a positioning cavity. The steel wire hoop 7 adopts a steel wire rope, two steel wire hoops 7 are arranged above each pad 6, threaded columns are arranged at the two ends of the steel wire rope, through holes are arranged on the horizontal bracket 1, the threaded columns penetrate through the through holes, and lock nuts are arranged on the threaded columns, so that the tightening degree of the steel wire hoop 7 to the cylindrical part can be adjusted through the lock nuts.

[0060] In step S2, the in-core component is lifted to the pad 6, and then the steel wire hoop 7 is tightened around the in-core component, so that the in-core component is kept stable.

[0061] During the transportation, some unexpected risks can occur, in order to evaluate the reliability of the transportation scheme, before step S3, a transportation model is established, the transportation model comprises a transportation vehicle, a support tool fixed on the transportation vehicle and an in-pile component fixed in the support tool; a transportation route is planned, the transportation process is simulated by using Emulate3D software, and the operation parameters of the transportation vehicle are obtained; in step S3, the transportation vehicle is operated according to the operation parameters obtained by simulation.

[0062] The Emulate3D software is a commonly used industrial automation system simulation software, which provides a high-fidelity logistics system animation, simulation and control platform, supports agile design, scheme verification and process optimization and the like. In the present application, the transportation model and the transportation route are input into the Emulate3D software, the transportation process is simulated by using the Emulate3D software, during the simulation, the transportation model can be operated under various operation parameters, the transportation conditions under various operation parameters are obtained, and the better operation parameters ensuring the safety of the in-pile component are determined. The operation parameters can include the acceleration when the transportation vehicle starts, the acceleration when the transportation vehicle brakes, the straight running speed, the turning speed, the turning radius and the like. The forces of the in-pile component on the support tool under various operation parameters can also be obtained. There can be various transportation routes, the transportation model is simulated in the transportation process of each transportation route, and thus the best transportation route is obtained.

[0063] During the transportation, one end of the in-pile component faces the vehicle head, and the other end faces the vehicle tail, the biggest instability of the in-pile component comes from the inertia and centrifugal force during the turning, when the transportation vehicle turns, the in-pile component is subjected to the inertia and centrifugal force, which causes the uneven force of the in-pile component on the pad 6, assuming that the transportation vehicle turns left, the in-pile component exerts greater force on the right end of the pad 6, if the inertia or centrifugal force is too large, the in-pile component can roll to the right side, and it is difficult to keep stable. Therefore, it is necessary to strictly control the inertia and centrifugal force of the in-pile component during the turning.

[0064] In the present application, as shown in Figure 5 The lower parts of the two ends of the pad 6 are respectively provided with a first pressure sensor 61 and a second pressure sensor 62, and the first pressure sensor 61 and the second pressure sensor 62 are connected with a controller 63.

[0065] During the simulation of the transportation process, the pressure difference of the two ends of the pad 6 on the horizontal bracket 1 under various turning radii and turning speeds is obtained when the transportation vehicle passes through each curve, the limit pressure difference when the in-pile component is fixed to fail is determined, and the turning radius and the turning speed when the transportation vehicle passes through each curve are determined.

[0066] In step S3, the transport vehicle turns according to the determined turning radius and turning speed, and the first pressure sensor 61 and the second pressure sensor 62 detect the pressure of the pad 6 on the horizontal bracket 1 in real time and transmit the detection signal to the controller 63, the controller 63 calculates the pressure difference of the first pressure sensor 61 and the second pressure sensor 62, and judges whether the in-pile component is fixedly failed.

[0067] In the Emulate3D software simulation process, the pressure of the first pressure sensor 61 and the second pressure sensor 62 can be automatically obtained by the software. The limit pressure difference is the pressure difference detected by the first pressure sensor 61 and the second pressure sensor 62 when the in-pile component is fixedly failed. The Emulate3D software is used to simulate the fixed failure of the in-pile component during turning, the turning radius and the turning speed at the time of fixed failure are recorded, the pressure values of the first pressure sensor 61 and the second pressure sensor 62 at the time of fixed failure are obtained, and the limit pressure difference is calculated. The turning speed of the transport vehicle through each bend should be less than the turning speed at the time of fixed failure, and the turning radius should be greater than the turning radius at the time of fixed failure.

[0068] First, the appropriate turning radius and turning speed are determined by simulating the turning condition, which can ensure the safety of transportation. At the same time, in the formal transportation, the first pressure sensor 61 and the second pressure sensor 62 detect the pressure value of the pad 6 on the horizontal bracket 1 in real time and calculate the pressure difference, when the pressure difference approaches the limit pressure difference obtained by simulation, the transport vehicle reduces the turning speed, which further ensures the safety of transportation.

[0069] During transportation, the support tool has a large inertia when the transport vehicle starts and brakes. In order to prevent the support tool from sliding on the carriage floor 100 of the transport vehicle, as shown in Figure 6 The present application sets two detachable limiting frames 101 on the carriage floor 100 of the transport vehicle, the limiting frame 101 is a half-rectangular ring, and the two limiting frames 101 form a rectangular limiting window 102.

[0070] After the support tool and the in-pile component are lifted to the carriage floor 100, the two limiting frames 101 are installed on the carriage floor 100, and the inner side wall of the limiting frame 101 is attached to the outer side wall of the horizontal bracket 1.

[0071] The limiting frame 101 can be fixed to the carriage floor 100 by screws. Specifically, after the support tool is lifted to the carriage floor 100, according to the position of the horizontal bracket 1, threaded holes are drilled on the carriage floor 100, and then the limiting frame 101 is installed on the carriage floor 100 by screws, so that the limiting frame 101 can effectively attach to the horizontal bracket 1 and effectively limit the horizontal bracket 1, preventing the support tool from sliding.

[0072] After transporting the support fixtures and internal components to the installation site, first remove the limit frame 101, and then hoist the support fixtures and internal components to the ground.

[0073] To further detect whether there is a significant shift in the position of the internal components, such as... Figure 7 As shown, multiple monitoring stands 103 are provided on both limit frames 101. A horizontal fixed column 104 is provided on the monitoring stand 103. A sliding sleeve 105 is fitted on the outer wall of the end of the fixed column 104 facing the limit window 102. One end of the sliding sleeve 105 is connected to an arc-shaped transmission plate 106 through a third pressure sensor 107. A spring 108 is provided between the monitoring stands 103 at the other end.

[0074] In step S3, the transmission plate 106 is in contact with the outer wall of the in-core component, and the spring 108 is in a compressed state. The offset of the in-core component is detected by the third pressure sensor 107.

[0075] The monitoring stand 103 is detachably connected to the limiting frame 101. After the limiting frame 101 is installed on the floor 100 of the vehicle, the monitoring stand 103 is then installed on the limiting frame 101. The spring 108 is telescopic, ensuring that the transmission plate 106 is in contact with the outer wall of the in-stack component. After the transmission plate 106 is in stable contact with the in-stack component, the pressure value detected by the third pressure sensor 107 is recorded. During transportation, when the in-stack component shows significant displacement, the transmission plate 106 will shift synchronously with the in-stack component, the length of the spring 108 will change, the elastic force will also change, and the pressure value detected by the third pressure sensor 107 will also change. The displacement of the in-stack component can be calculated based on the change in pressure value. When the displacement of the in-stack component reaches a set value, transportation will be stopped in time and the position of the in-stack component will be adjusted. There can be four monitoring stands 103, located on the left and right sides of both ends of the in-stack component.

[0076] The inner wall of the end support 3 is provided with multiple pairs of connecting frames 8 perpendicular to the end support 3. Each pair of connecting frames 8 has a support plate 9 at the end away from the end support 3. In step S4, after the support fixture is rotated to a vertical position, the support plate 9 supports the in-core components. There can be two support plates 9, which can stably support the in-core components. After the in-core components are placed on the pad block 6, the end face of the in-core components can fit against the support plate 9.

[0077] To prevent axial movement of the internal components, the inner wall of the lifting frame 2 is provided with an adjusting column 12 that is threadedly engaged with the lifting frame 2, and a limit block 13 is provided at the end of the adjusting column 12. In step S2, after the internal components are hoisted onto the horizontal bracket 1, the adjusting column 12 is rotated to drive the limit block 13 to press the end face of the internal components.

[0078] In order to improve the balance of the force borne by the lifting frame 2 and the end support 3, improve the structural strength and stability of the support tool, a plurality of detachable pull rods 14 are arranged between the top of the end support 3 and the top of the lifting frame 2 when the support tool is adjusted to the vertical state together with the in-pile component. In step S2, after the in-pile component is fixed, the two ends of the pull rod 14 are installed to the top of the end support 3 and the lifting frame 2. After step S4, the pull rod 14 is removed. When the lifting device drives the lifting frame 2 to move upward, the lifting frame 2 simultaneously transmits the lifting force to the pull rod 14 and the horizontal bracket 1, and then the pull rod 14 and the horizontal bracket 1 transmit the force to the end support 3, so that the force borne by the two ends of the end support 3 and the lifting frame 2 is uniform, thereby improving the stability of the structure.

[0079] After the in-pile component is transported to the installation site, the support tool can be directly hoisted together with the in-pile component to the ground, and the support tool is supported by the ground. When the lifting frame 2 starts to move upward, the horizontal bracket 1 is separated from the ground, and at this time the entire support tool is supported by the connecting plate 4. In order to make the entire support tool rotate from the horizontal state to the vertical state, the lifting device needs to make an arc motion, which is difficult to control. If the lifting device does not make an arc motion, the connecting plate 4 will slide on the ground, affecting the stability.

[0080] In order to further improve the stability of the support tool, as shown in Figure 8 , a horizontal movable support plate 201 is arranged at the installation site, the movable support plate 201 is connected with a driving mechanism 202 for driving the horizontal linear motion of the movable support plate 201, one end of the movable support plate 201 is provided with a pair of connecting ears 203, the connecting ears 203 are provided with a worm shaft 204, the worm shaft 204 is fixedly provided with a vertical baffle 205, and the worm shaft 204 is connected with a turbine 206, and the turbine 206 is connected with a motor 207. When the motor 207 operates, the worm shaft 204 can be driven to rotate through the turbine 206, thereby driving the baffle 205 to rotate, so that the baffle 205 rotates from the vertical state to the horizontal state, and when the baffle 205 rotates to the horizontal state, the upper surface of the baffle 205 and the upper surface of the movable support plate 201 are in the same horizontal plane.

[0081] In step S4, the support tool together with the in-pile component is first hoisted to the movable support plate 201 by the lifting device, and the outer side wall of the end support 3 contacts the side wall of the baffle 205, as shown in Figure 9 . The baffle 205 plays a role of limiting the support tool, preventing the connecting plate 4 from sliding on the movable support plate 201 during lifting.

[0082] The lifting device is connected with the lifting frame 2, the lifting device pulls the lifting frame 2 to move vertically upward, meanwhile, the driving mechanism 202 drives the movable supporting plate 201 to move linearly, the movable supporting plate 201 drives the connecting plate 4 to move horizontally towards the lifting frame 2, and the motor 207 drives the worm shaft 204 to rotate through the turbine 206, so that the baffle 205 is gradually rotated from the vertical state to the horizontal state, as shown in the figure. Figure 10 As shown in the figure, the lifting frame 2 moves along the direction a, the movable supporting plate 201 moves along the direction b, and the baffle 205 rotates along the direction c.

[0083] Before lifting, the motion track of the supporting tool can be simulated in simulation software, the lifting speed of the lifting device, the moving speed of the movable supporting plate 201 and the rotating speed of the baffle 205 are determined, so that the moving speed of the lifting frame 2, the moving speed of the movable supporting plate 201 and the rotating speed of the baffle 205 are matched when the lifting is formally carried out.

[0084] When the lifting is started, the horizontal bracket 1 of the supporting tool is away from the movable supporting plate 201, and the whole supporting tool is supported by the connecting plate 4, if the connecting plate 4 is only driven to move horizontally by the friction force between the movable supporting plate 201 and the connecting plate 4, the connecting plate 4 is easy to slide relative to the movable supporting plate 201, therefore, the baffle 205 is arranged on the movable supporting plate 201, the baffle 205 moves synchronously with the movable supporting plate 201, and supports the end support 3, so that the lower end of the supporting tool can stably move synchronously with the movable supporting plate 201.

[0085] The upper end (the lifting frame 2) of the supporting tool is pushed vertically upward, the lower end (the end support 3 and the connecting plate 4) of the supporting tool moves horizontally, the motion of the two is combined, so that the supporting tool can be gradually rotated to the vertical state, and the lifting device only needs to drive the lifting frame 2 to move vertically upward, the operation is simple and convenient, and the sliding of the connecting plate 4 is avoided, so that the stability is ensured.

[0086] The movable supporting plate 201 can be installed on the rack, and the horizontal supporting frame is arranged on the rack, when the baffle 205 is rotated to the horizontal state, the baffle 205 can fall on the supporting frame. The driving mechanism 202 can be a gear and rack mechanism driven by a speed reduction motor, a screw mechanism and the like.

[0087] The supporting seat 5 of the present application is as shown in the figure. Figure 4As shown, the support tool includes a bottom plate 51 and an arc-shaped mounting plate 52, the mounting plate 52 is connected to and detachably connected with the connecting plate 4, the side of the bottom plate 51 is in the same plane with the outer side of the end support 3, and a reinforcing plate 53 is arranged between the bottom plate 51 and the mounting plate 52, and the mounting plate 52 is connected with the connecting plate 4 through screws. During transportation, the support seat 5 does not need to be installed. After the support tool is rotated to the vertical state as a whole, the support tool as a whole can be driven to move upward by a distance, so that the end support 3 is away from the ground, and then the support seat 5 is installed on the connecting plate 4, so as to have enough operation space. After the installation of the support seat 5 is completed, the tool as a whole is lowered to the movable support plate 201, and the support seat 5 and the end support 3 simultaneously support the tool.

[0088] The preferred embodiments of the present application have been described above with reference to the drawings, but the present application is not limited to the above examples, and various modifications and changes can be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
