Description

Technical Field

[0001] This invention belongs to the field of parts transportation and lifting equipment, and in particular a method for transporting and lifting components within a stack. Background Technology

[0002] A cylindrical reactor internal component, used in a nuclear power plant reactor, is manufactured in the workshop and then transported to the nuclear power plant for installation inside the reactor. To ensure stability during transport, the internal component is typically horizontally fixed to supporting fixtures. After arriving at the nuclear power plant, the fixtures are released, and the internal component is then lifted to a vertical position before being placed into the reactor for installation. Due to the large size of this internal component (8500mm in length, 3500mm in outer diameter, and relatively heavy), its cylindrical shape presents significant challenges in lifting it from a horizontal to a vertical position, making the lifting process difficult. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for transporting and lifting in-core components, which facilitates the transportation, lifting and installation of in-core components.

[0004] To solve the above problems, the technical solution adopted by the present invention is: a method for transporting and lifting in-core components, comprising the following steps: S1. Prepare a support fixture, which includes a horizontal bracket. One end of the horizontal bracket is provided with a detachable lifting frame, which is perpendicular to the horizontal bracket. The other end of the horizontal bracket is connected to a vertical end bracket through a 1 / 4 circular connecting plate. The outer wall of the connecting plate is provided with a detachable support seat. The horizontal bracket is provided with a positioning component. S2. Hoist the in-stack components onto the horizontal bracket and fix the in-stack components horizontally onto the horizontal bracket using the positioning components; S3. Transport vehicles are used to transport the supporting tooling along with the stacked internal components to the installation site; S4. Connect the lifting equipment to the lifting frame, and use the lifting equipment to pull the lifting frame upward, so that the entire support fixture rotates upward. During the rotation, use the connecting plate to support the entire support fixture until the support fixture rotates to a vertical position and the stacked components fall onto the end support. S5. Install the support base onto the outer wall of the connecting plate; S6. Remove the lifting frame, release the fixation on the in-core components, and the lifting equipment will move the in-core components upwards, so that the in-core components are freed from the supporting fixtures, and then lift the in-core components into the reactor.

[0005] Furthermore, the positioning component includes multiple arc-shaped pads, and a wire clamp is provided above the pads. The two ends of the wire clamp are detachably connected to the horizontal bracket, and the wire clamp and the pads form a positioning cavity. In step S2, the internal components are hoisted onto the pad block, and then the internal components are tightened with steel wire clamps.

[0006] Further, before step S3, a transportation model is established, which includes a transport vehicle, a support fixture fixed on the transport vehicle, and stack components fixed in the support fixture; the transportation route is planned, and the transportation process is simulated using Emulate3D software to obtain the operating parameters of the transport vehicle; In step S3, the transport vehicle operates according to the operating parameters obtained from the simulation.

[0007] Furthermore, a first pressure sensor and a second pressure sensor are respectively provided below both ends of the pad, and the first pressure sensor and the second pressure sensor are connected to a controller. During the simulated transportation process, when the transport vehicle passes through each curve, the pressure difference between the two ends of the pad block and the horizontal bracket is obtained under various turning radii and turning speeds. The ultimate pressure difference when the internal components fail to be fixed is determined, and the turning radius and turning speed of the transport vehicle when passing through each curve are determined. In step S3, the transport vehicle turns according to the determined turning radius and turning speed, and the first pressure sensor and the second pressure sensor detect the pressure of the two ends of the pad block on the horizontal bracket in real time and transmit the detection signal to the controller. The controller calculates the pressure difference between the first pressure sensor and the second pressure sensor and determines whether the internal components have failed to be fixed.

[0008] Furthermore, in step S3, two detachable limiting frames are provided on the floor of the transport vehicle. The limiting frames are semi-rectangular rings, and the two limiting frames form a rectangular limiting window. After hoisting the support fixtures and internal components to the bottom plate of the car body, install the two limiting frames onto the bottom plate of the car body, with the inner side wall of the limiting frames fitting against the outer side wall of the horizontal bracket. After transporting the support fixtures and internal components to the installation site, first remove the limit frame, and then hoist the support fixtures and internal components to the ground.

[0009] Furthermore, multiple monitoring stands are provided on both limit frames, and horizontal fixed columns are provided on the monitoring stands. A sliding sleeve is fitted on the outer wall of the end of the fixed column facing the limit window. One end of the sliding sleeve is connected to an arc-shaped transmission plate through a third pressure sensor, and a spring is provided between the monitoring stands at the other end. In step S3, the transmission plate is in contact with the outer wall of the in-core component, and the spring is in a compressed state. The offset of the in-core component is detected by the third pressure sensor.

[0010] Furthermore, the inner wall of the end support is provided with multiple pairs of connecting frames perpendicular to the end support, and a support plate is provided at the end of each pair of connecting frames away from the end support. In step S4, after the support fixture is rotated to a vertical state, the support plate supports the stack components.

[0011] Furthermore, the inner wall of the lifting frame is provided with an adjusting column that is threadedly engaged with the lifting frame, and the end of the adjusting column is provided with a limiting block; in step S2, after the in-core component is hoisted onto the horizontal bracket, the adjusting column is rotated to drive the limiting block to press the end face of the in-core component.

[0012] Furthermore, multiple detachable tie rods are provided between the top of the end support and the top of the lifting frame; in step S2, after the stack components are fixed, the two ends of the tie rods are installed to the top of the end support and the lifting frame; after step S4, the tie rods are removed.

[0013] Furthermore, a horizontal movable support plate is set up at the installation site. The movable support plate is connected to a drive mechanism that drives the movable support plate to move horizontally and linearly. One end of the movable support plate is provided with a pair of connecting ears. A worm shaft is provided on the connecting ears. A vertical baffle is fixed on the worm shaft. The worm shaft is connected to a worm wheel, and the worm wheel is connected to a motor. In step S4, the supporting fixture and the stacked components are first lifted and transported to the movable support plate using lifting equipment, and the outer wall of the end bracket contacts the side wall of the baffle. Then connect the lifting equipment to the lifting frame. The lifting equipment pulls the lifting frame vertically upward. At the same time, the drive mechanism drives the movable support plate to move linearly. The movable support plate then drives the connecting plate to move horizontally in the direction of the lifting frame. The motor drives the worm shaft to rotate through the worm gear, so that the baffle gradually rotates from the vertical state to the horizontal state.

[0014] The beneficial effects of this invention are: when transporting stack components, the stack components are placed horizontally on a horizontal bracket, and the positioning components are used to position the stack components, so that the stack components remain stable.

[0015] When transporting the in-core components to the installation site, the lifting equipment is connected to the lifting frame, which pulls the lifting frame upward, causing the entire tooling, along with the in-core components, to rotate to a vertical position. During the rotation, the positioning components maintain the positioning of the in-core components, preventing them from rolling and improving their stability.

[0016] This invention uses a cuboid-shaped support fixture for position adjustment, replacing direct adjustment of the cylindrical internal components. The cuboid shape provides better stability and prevents uncontrollable movements such as rolling, thus reducing lifting difficulty. Furthermore, the entire support fixture is supported by a quarter-circular connecting plate, which serves as a guide, support, and positioner, ensuring smooth rotation of the support fixture and further reducing lifting difficulty and safety risks.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] The method for transporting and lifting in-core components according to the present invention includes the following steps: S1. Prepare the support fixture, such as... Figures 1 to 4 As shown, it includes a horizontal bracket 1, one end of which is provided with a detachable lifting bracket 2, the lifting bracket 2 being perpendicular to the horizontal bracket 1, and the other end of the horizontal bracket 1 being connected to a vertical end bracket 3 via a 1 / 4 circular connecting plate 4, the outer wall of which is provided with a detachable support seat 5; a positioning component is provided on the horizontal bracket 1.

[0020] Horizontal bracket 1 is used to support and position the in-core components during transportation. Positioning components are used to fix the in-core components to the horizontal bracket 1, preventing them from swaying during transport. During transportation, lifting frame 2 and end supports 3 are located at both ends of the in-core components, providing auxiliary positioning and improving the stability and safety of the in-core components. Horizontal bracket 1 can be welded from various existing steel profiles or bolted together to form a frame structure, as long as it has sufficient load-bearing capacity. After the in-core components are transported to the installation site, lifting frame 2 is used to connect with lifting equipment, allowing the entire support fixture to be lifted and the position of the fixture and in-core components to be adjusted. The lower end of the outer wall of connecting plate 4 is tangent to the lower surface of horizontal bracket 1, and the upper end of the outer wall of connecting plate 4 is tangent to the outer side of end supports 3.

[0021] S2. Hoist the internal components onto the horizontal bracket 1 and fix them horizontally onto the horizontal bracket 1 using the positioning components.

[0022] During workshop processing, the internal components are in a horizontal position, and the internal components themselves are equipped with lifting lugs for auxiliary lifting. Therefore, the process of lifting the internal components to the horizontal bracket 1 is not particularly difficult. Similarly, the process of directly lifting the horizontal support fixture is also not particularly difficult. The more difficult lifting process is changing the position of the internal components, that is, adjusting the internal components from a horizontal position to a vertical position.

[0023] S3. Transport vehicles are used to transport the supporting fixtures and internal components to the installation site.

[0024] The transport vehicle can be a large truck. The support fixtures, along with the reactor internals, are hoisted onto the transport vehicle, which is then used to transport them to the installation site at the nuclear power plant. During installation, the support fixtures, along with the reactor internals, can first be hoisted to the ground, and then the reactor internals can be adjusted from a horizontal to a vertical position.

[0025] S4. Connect the lifting equipment to the lifting frame 2, and use the lifting equipment to pull the lifting frame 2 upward, so that the entire support fixture rotates upward. During the rotation, the connecting plate 4 supports the entire support fixture until the support fixture rotates to a vertical position and the stacked components fall onto the end support 3.

[0026] The lifting frame 2 is equipped with lifting rods 10, which can be one or two. The lifting equipment can be connected to the lifting rods 10, thereby pulling the lifting frame 2 upward through the lifting rods 10. The lifting frame 2 then drives the entire support fixture, along with the stacked components, to rotate. During the rotation of the support fixture, the connecting plate 4 supports the entire support fixture. Since the connecting plate 4 is 1 / 4 circular, it can play a good guiding role, ensuring smooth and stable rotation of the support fixture, reducing adjustment difficulty, and improving safety.

[0027] During the rotation of the support fixture, the internal components remain within the support fixture and are kept stable by the positioning components, which can prevent uncontrollable movements such as rolling of the internal components.

[0028] This invention uses a cuboid-shaped support fixture to adjust its position, instead of directly adjusting the position of the cylindrical internal components. The cuboid-shaped support fixture has better stability and will not exhibit uncontrollable movements such as rolling, thus reducing the difficulty of lifting.

[0029] S5. Install the support base 5 onto the outer wall of the connecting plate 4.

[0030] After adjusting the support fixture to a vertical position, the end bracket 3 supports the entire support fixture. However, due to the small size of the end bracket 3 and the large height of the support fixture, there is a gap below the arc-shaped connecting plate 4, preventing it from contacting the support surface and resulting in poor stability of the support fixture. To improve the stability of the support fixture, this invention installs a support seat 5 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 together with the end bracket 3, supports the support fixture, thereby improving its stability and preventing it from tipping over.

[0031] S6. Remove the lifting frame 2, release the fixation on the in-core components, and the lifting equipment will move the in-core components upward so that the in-core components are detached from the support fixtures and then hoist the in-core components into the reactor.

[0032] The lifting frame 2 can be connected to the horizontal bracket 1 by multiple bolts. After the support fixture is adjusted to a vertical position, the in-core components are supported by the end bracket 3. After the lifting frame 2 is removed and the positioning components are released from fixing the in-core components, the in-core components are no longer constrained by the support fixture. At this time, the lifting equipment can be connected to the upper end of the in-core components. The lifting equipment can be used to move the in-core components vertically upward, so that the in-core components are separated from the support fixture. Then, the in-core components are hoisted to the top of the reactor and vertically lowered into the reactor.

[0033] In this invention, the positioning component can employ various existing mechanisms capable of fixing cylindrical parts. Specifically, the positioning component includes multiple arc-shaped pads 6, which are fixedly mounted on a horizontal bracket 1. The upper surface of the pad 6 is arc-shaped, and the diameter of the upper surface of the pad 6 is the same as the outer diameter of the internal component, allowing the upper surface of the pad 6 to conform to the outer wall of the internal component. There can be two pads 6, supporting both ends of the internal component respectively. A wire clamp 7 is provided above the pad 6, with both ends of the wire clamp 7 connected to the horizontal bracket 1. The wire clamp 7 and the pad 6 form a positioning cavity. The wire clamp 7 is made of wire rope, with two wire clamps 7 provided above each pad 6. Threaded posts are provided at both ends of the wire rope. A through hole is provided on the horizontal bracket 1, through which the threaded post passes, and a locking nut is provided on the threaded post. The tightness of the wire clamp 7 on the cylindrical part can be adjusted by the locking nut.

[0034] In step S2, the internal components are hoisted onto the pad block 6, and then the internal components are tightened with steel wire clamps 7 to keep them stable.

[0035] During transportation, some unexpected risks may occur. In order to assess the reliability of the transportation plan, a transportation model is established before step S3. The transportation model includes a transportation vehicle, a support fixture fixed on the transportation vehicle, and stack components fixed in the support fixture. The transportation route is planned, and the transportation process is simulated using Emulate3D software to obtain the operating parameters of the transportation vehicle. In step S3, the transportation vehicle operates according to the operating parameters obtained from the simulation.

[0036] Emulate3D is a commonly used industrial automation system simulation software that provides a high-fidelity animation, simulation, and control platform for logistics systems, supporting agile design, solution verification, and process optimization. This invention inputs a transportation model and route into Emulate3D, using the software to simulate the transportation process. During simulation, the transportation model can run under various operating parameters to obtain transportation conditions under different parameters, thereby determining the optimal operating parameters to ensure the safety of the stack components. Operating parameters can include the acceleration of the transport vehicle at startup, acceleration during braking, straight-line speed, turning speed, and turning radius. The forces exerted by the stack components on the supporting fixtures under various operating parameters can also be obtained. Multiple transportation routes can also be used, simulating the transportation process of the model on each route to obtain the optimal transportation route.

[0037] During transportation, one end of the stack components faces the front of the vehicle, and the other end faces the rear. The greatest instability of the stack components comes from the inertia and centrifugal force during turns. When the transport vehicle turns, the stack components are subjected to inertia and centrifugal force, resulting in uneven force on the pad block 6. Assuming that when the transport vehicle turns left, the stack components exert a greater force on the right end of the pad block 6, if the inertia or centrifugal force is too large, the stack components may roll to the right and become difficult to stabilize. Therefore, it is necessary to strictly control the inertia and centrifugal force on the stack components during turns.

[0038] In this invention, such as Figure 5 As shown, a first pressure sensor 61 and a second pressure sensor 62 are respectively installed below both ends of the pad 6, and the first pressure sensor 61 and the second pressure sensor 62 are connected to a controller 63.

[0039] During the simulated transportation process, when the transport vehicle passes through each curve, the pressure difference between the two ends of the pad 6 and the horizontal bracket 1 is obtained to determine the ultimate pressure difference when the internal components fail to fix, and to determine the turning radius and turning speed of the transport vehicle when passing through each curve.

[0040] 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 two ends of the pad block 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 between the first pressure sensor 61 and the second pressure sensor 62 and determines whether the internal components have failed to be fixed.

[0041] During the Emulate3D software simulation, the pressure magnitudes of the first pressure sensor 61 and the second pressure sensor 62 can be automatically obtained. The ultimate pressure difference is the pressure difference detected by the first pressure sensor 61 and the second pressure sensor 62 when the internal components fail to hold. Emulate3D software is used to simulate the scenario of internal component failure during a turn, recording the turning radius and turning speed at the time of failure, obtaining the pressure values ​​of the first pressure sensor 61 and the second pressure sensor 62 at the time of failure, and calculating the ultimate pressure difference. The turning speed of the transport vehicle when passing through each curve should be less than the turning speed at the time of failure, and the turning radius should be greater than the turning radius at the time of failure.

[0042] First, simulated turning conditions are used to determine the appropriate turning radius and speed, ensuring transportation safety. Simultaneously, during actual transport, the first pressure sensor 61 and the second pressure sensor 62 continuously monitor the pressure values ​​of the two ends of the pad 6 against the horizontal bracket 1 and calculate the pressure difference. When the pressure difference approaches the simulated limit pressure difference, the transport vehicle is controlled to reduce its turning speed, further ensuring transportation safety.

[0043] During transportation, the supporting fixture has significant inertia when the transport vehicle starts and brakes. To prevent the supporting fixture from sliding on the floor 100 of the transport vehicle, such as... Figure 6 As shown, the present invention provides two detachable limiting frames 101 on the floor 100 of the transport vehicle. The limiting frames 101 are semi-rectangular rings, and the two limiting frames 101 form a rectangular limiting window 102.

[0044] After the supporting fixtures and internal components are hoisted to the car floor 100, the two limiting frames 101 are installed on the car floor 100, with the inner side wall of the limiting frame 101 fitting against the outer side wall of the horizontal bracket 1.

[0045] The limiting frame 101 can be fixed to the carriage floor 100 with screws. Specifically, after the supporting fixture is hoisted to the carriage floor 100, threaded holes are drilled on the carriage floor 100 according to the position of the horizontal bracket 1. Then, the limiting frame 101 is installed on the carriage floor 100 with screws to ensure that the limiting frame 101 can effectively fit the horizontal bracket 1 and effectively limit the horizontal bracket 1 to prevent the supporting fixture from sliding.

[0046] 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.

[0047] 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. 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] When adjusting the support fixture along with the internal components to a vertical position, in order to improve the balance of forces on the lifting frame 2 and the end support 3, and to improve the structural strength and stability of the support fixture, multiple detachable tie rods 14 are installed between the top of the end support 3 and the top of the lifting frame 2. In step S2, after the internal components are fixed, the two ends of the tie rods 14 are installed on the top of the end support 3 and the lifting frame 2. After step S4, the tie rods 14 are removed. When the lifting equipment moves the lifting frame 2 upward, the lifting frame 2 transmits the lifting force to the tie rods 14 and the horizontal bracket 1 simultaneously, and then from the tie rods 14 and the horizontal bracket 1 to the end support 3. The end support 3 and the two ends of the lifting frame 2 are evenly stressed, improving the stability of the structure.

[0052] After the stack components are transported to the installation site, the support fixture, along with the stack components, can be directly hoisted to the ground, where it is supported by ground supports. When the lifting frame 2 begins to move upwards, the horizontal bracket 1 detaches from the ground, and the entire support fixture is then supported by the connecting plate 4. To rotate the entire support fixture from a horizontal to a vertical position, the lifting equipment needs to make an arc-shaped movement, which is quite difficult to control. If the lifting equipment does not make this arc-shaped movement, the connecting plate 4 will slide on the ground, affecting stability.

[0053] To further improve the stability of the supporting fixtures, such as Figure 8 As shown, a horizontal movable support plate 201 is set up at the installation site. The movable support plate 201 is connected to a drive mechanism 202 that drives the movable support plate 201 to move horizontally and linearly. One end of the movable support plate 201 is provided with a pair of connecting ears 203. A worm shaft 204 is provided on the connecting ears 203. A vertical baffle 205 is fixedly provided on the worm shaft 204. The worm shaft 204 is connected to a turbine 206, and the turbine 206 is connected to a motor 207. When the motor 207 is running, it can drive the worm shaft 204 to rotate through the turbine 206, thereby driving the baffle 205 to rotate, so that the baffle 205 rotates from a vertical state to a horizontal state. When the baffle 205 rotates to a horizontal state, the upper surface of the baffle 205 is at the same horizontal plane as the upper surface of the movable support plate 201.

[0054] In step S4, the supporting fixture, along with the internal components, is first lifted onto the movable support plate 201 using lifting equipment, with the outer wall of the end bracket 3 contacting the side wall of the baffle 205. Figure 9 As shown. The baffle 205 serves to limit the movement of the support fixture and prevent the connecting plate 4 from sliding on the movable support plate 201 during the lifting process.

[0055] The lifting equipment is then connected to the lifting frame 2. The lifting equipment pulls the lifting frame 2 vertically upward. Simultaneously, the drive mechanism 202 drives the movable support plate 201 to move linearly. The movable support plate 201 then drives the connecting plate 4 to move horizontally towards the lifting frame 2. Furthermore, the motor 207 drives the worm shaft 204 to rotate via the worm gear 206, causing the baffle 205 to gradually rotate from a vertical state to a horizontal state. Figure 10 As shown, the lifting frame 2 moves along direction a, the movable support plate 201 moves along direction b, and the baffle 205 rotates along direction c.

[0056] Before lifting, the motion trajectory of the support fixture can be simulated in simulation software to determine the lifting speed of the lifting equipment, the moving speed of the movable support plate 201 and the rotation speed of the baffle 205, so as to ensure that the upward movement speed of the lifting frame 2, the moving speed of the movable support plate 201 and the rotation speed of the baffle 205 are matched during the actual lifting.

[0057] When lifting begins, the horizontal bracket 1 of the support fixture moves away from the movable support plate 201. The entire support fixture is supported by the connecting plate 4. If the connecting plate 4 is moved horizontally by the friction between the movable support plate 201 and the connecting plate 4, the connecting plate 4 is prone to sliding relative to the movable support plate 201. Therefore, a baffle 205 is provided on the movable support plate 201. The baffle 205 moves synchronously with the movable support plate 201 and supports the end bracket 3 to ensure that the lower end of the support fixture can move stably and synchronously with the movable support plate 201.

[0058] The upper end of the support fixture (lifting frame 2) is pushed vertically upward, while the lower end of the support fixture (end bracket 3 and connecting plate 4) moves horizontally. The combined movement of the two allows the support fixture to gradually rotate to a vertical position. The lifting equipment only needs to move the lifting frame 2 vertically upward, making operation simple and convenient. At the same time, it avoids the sliding of the connecting plate 4, ensuring stability.

[0059] The movable support plate 201 can be mounted on the frame, and a horizontal support frame can be set on the frame. When the baffle 205 rotates to the horizontal position, the baffle 205 can fall on the support frame. The drive mechanism 202 can be a commonly used drive structure such as a gear and rack mechanism or a lead screw mechanism driven by a geared motor.

[0060] The support base 5 of the present invention is as follows Figure 4 As shown, the fixture includes a base plate 51 and an arc-shaped mounting plate 52. The mounting plate 52 is attached to and detachably connected to the connecting plate 4. The side of the base plate 51 is on the same plane as the outer side of the end bracket 3, and a reinforcing plate 53 is provided between the base plate 51 and the mounting plate 52. The mounting plate 52 is connected to the connecting plate 4 by screws. During transportation, the support base 5 does not need to be installed.
