Description

Technical Field

[0001] This invention belongs to the field of superconducting coil assembly technology, and specifically relates to a dynamic assembly device and method for magnetically pulled single-crystal multi-coil. Background Technology

[0002] The magnetically pulled single-crystal coil is designed in a ring shape, and the corresponding magnetically pulled single-crystal coil support frame is placed flat on the ground. Its mounting holes are actually parallel to the ground. The mounting holes suitable for matching the mounting holes of the support frame can only be set on the side of the magnetically pulled single-crystal superconducting coil.

[0003] Currently, the assembly method for magnetically pulled single-crystal coils involves using a crane hoisting device to directly pass the sling through the inner ring of a magnetically pulled single-crystal coil. The two ends of the sling are directly fixed to the hooks of the crane hoisting device. After the magnetically pulled single-crystal superconducting coil is close to the mounting side wall of the support frame, it is then fixed with bolts. This method not only results in unstable installation due to the obstruction of the sling side during installation, preventing the coil from fitting snugly against the mounting side wall, but also allows only one coil to be installed at a time, leading to low installation efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where the coil cannot fit snugly against the mounting sidewall, resulting in insecure installation and low installation efficiency as only one coil can be installed at a time.

[0005] To address the aforementioned technical problems, embodiments of the present invention disclose a dynamic assembly device for a magnetically pulled single-crystal multi-coil system. The coils have an annular cross-section perpendicular to their thickness direction. The dynamic assembly device is used to install the coils to be installed from among multiple coils onto the side wall of a coil frame. The dynamic assembly device includes a coil placement frame, a lifting bracket, and a propulsion assembly. The coil placement frame is used to place multiple coils in a vertical position, with the multiple coils spaced apart along the length of the coil placement frame. The lifting bracket includes a lifting device with a U-shaped structure, comprising a first and second crossbeam arranged at intervals, and a side beam. The length directions of the first and second crossbeams are parallel to each other, and one end of the first and second crossbeams passes through the side beam. The first and second crossbeams are fixedly connected, with one end forming a U-shaped opening. A hoisting part is provided on the side of the first crossbeam away from the second crossbeam for hoisting. The other end of the second crossbeam is used to insert multiple coils into the interior. The multiple coils are supported on the outer periphery of the second crossbeam and can move along the length direction of the second crossbeam. The thickness direction of the coils, the length direction of the coil placement frame, and the length direction of the second crossbeam are parallel to each other. A propulsion assembly is installed on the second crossbeam and can push the coil to be installed to move along the length direction of the second crossbeam. When the coil to be installed moves to the other end of the second crossbeam, the coil to be installed can be detachably fixedly connected to the side wall of the coil frame. The coil to be installed is the coil furthest from the side beam among the multiple coils.

[0006] Using the above technical solution, the dynamic assembly device includes a coil placement frame, a lifting bracket, and a propulsion assembly. Multiple coils in a vertical position are placed on the coil placement frame, and the multiple coils are spaced apart along the length of the coil placement frame. The lifting bracket includes a U-shaped lifting device, which includes a first crossbeam and a second crossbeam arranged at relative intervals, as well as side beams. The other end of the second crossbeam of the lifting device, i.e., the open end, is inserted into the interior of multiple coils, so that the multiple coils are supported on the outer periphery of the second crossbeam. A lifting part for lifting is provided on the side of the first crossbeam away from the second crossbeam. By using the lifting part in conjunction with lifting tools such as a lifting trolley, multiple coils and the lifting bracket are lifted and moved, realizing the single lifting of multiple coils. The coil furthest from the side beam among multiple coils, i.e., the coil to be installed, is positioned close to the side wall of the coil frame. A propulsion assembly, mounted on the second crossbeam, pushes the coil to be installed along the length of the second crossbeam, moving it to the end of the second crossbeam furthest from the side beam. At this point, the coil to be installed can be pressed against the side wall of the coil frame, allowing for a detachable and secure connection between the coil to be installed and the side wall of the coil frame. This provides a safer and more convenient detachable and secure connection. After the coil to be installed is complete, a new coil furthest from the side beam can be selected as the new coil to be installed. The coil and the lifting bracket are moved further, and the same method is used to bring the new coil to be installed close to the other side wall of the coil frame, allowing for a detachable and secure connection. This enables dynamic installation of multiple coils, improving installation efficiency.

[0007] According to another specific embodiment of the present invention, the dynamic assembly device for a magnetically pulled single-crystal multi-coil disclosed in this embodiment has a through hole extending along its length direction inside the second crossbeam, and a slot extending along the length direction of the second crossbeam on one side of the second crossbeam, the slot communicating with the through hole. The pushing assembly includes an abutment, a pushing member, and a first driving mechanism; the first driving mechanism is mounted on the side beam, the pushing member is located inside the through hole, one end is drivenly connected to the output end of the first driving mechanism, and the other end extends along the length direction of the second crossbeam to the other end of the second crossbeam; the abutment is adapted to the slot and engages with the slot, so that the abutment moves only along the length direction of the second crossbeam within the slot; the abutment is drivenly connected to the pushing member; if the abutment is located on the side of the coil to be installed near the first driving mechanism, the first driving mechanism drives the pushing member, causing the abutment to move along a first direction, and after the abutment abuts the coil to be installed, it pushes the coil to be installed to move along the first direction, which can move the coil to be installed to the other end of the second crossbeam; the first direction is the direction from one end of the second crossbeam to the other end.

[0008] Using the above technical solution, the propulsion assembly includes an abutment, a propulsion member, and a first driving mechanism. The propulsion member is located inside the through hole of the second crossbeam. The first driving mechanism is mounted on the side beam, so that the abutment member is located on the side of the coil furthest from the side beam (i.e., the coil to be installed) close to the first driving mechanism. The abutment member is adapted to and engaged with the slot on one side of the second crossbeam and is connected to the propulsion member for transmission. The first driving mechanism drives the propulsion member, causing the abutment member to move only along the first direction. After the abutment member abuts the coil to be installed, it continues to push the abutment member and the coil to be installed to move only along the first direction, which can move the coil to be installed to the other end of the second crossbeam. In this way, the abutment member, the propulsion member, and the first driving mechanism realize the propulsion of the coil to be installed to move along the first direction to the other end of the second crossbeam, which makes it easier for the coil to be installed to be tightly attached to the side wall of the coil frame, thereby realizing the installation of the two.

[0009] According to another specific embodiment of the present invention, the dynamic assembly device for a magnetically pulled single-crystal multi-coil disclosed in this embodiment of the present invention has a worm gear as the propulsion component and a first driving mechanism including a first driving component, a first bevel gear, and a second bevel gear. The first driving component is fixed on a side beam, and the output shaft of the first driving component is connected to the first bevel gear for transmission. The first bevel gear and the second bevel gear are perpendicular to each other and mesh with each other. The second bevel gear is fixedly connected to one end of the worm gear. The abutment component has a slot adapted to the worm gear on the side near the worm gear, and engages with the outer wall of the worm gear through the slot. Limiting protrusions are provided on both opposite sides of the abutment component, and limiting grooves adapted to the limiting protrusions are provided on the opposite side walls of the slot. The limiting grooves extend along the length direction of the second crossbeam. The abutment component engages with the slot through the limiting protrusions and the corresponding limiting grooves, so that the abutment component can only move along the length direction of the second crossbeam. The slot is provided with multiple engaging parts adapted to the abutment component, and the abutment component can engage with the slot through any one of the multiple engaging parts. If the abutment engages with the slot from a snap-in portion located on the side of the coil to be installed near the first drive mechanism, the first drive unit drives the first bevel gear to rotate, which in turn drives the second bevel gear and the worm gear to rotate, pushing the abutment and the coil to be installed to move along the first direction.

[0010] Using the above technical solution, the propulsion component is a worm gear, and the first driving mechanism includes a first driving component, a first bevel gear, and a second bevel gear. The abutment component is inserted into the slot from a snap-fit ​​portion located on the side of the coil to be installed near the first driving mechanism. The abutment component engages with the slot through a limiting protrusion and a limiting groove, and engages with the outer wall of the worm gear through the slot opening. The first driving component drives the first bevel gear to rotate, which in turn drives the second bevel gear and the worm gear to rotate, causing the abutment component to move along the first direction. After the abutment component abuts against the coil to be installed, it pushes the coil to be installed to move along the first direction. In this way, the movement of the coil to be installed along the first direction can be achieved through a simple structure.

[0011] According to another specific embodiment of the present invention, the dynamic assembly device for magnetically pulled single-crystal multi-coil disclosed in this embodiment of the present invention includes a support portion in the hoisting bracket. The support portion is fixed to the outer wall of the second crossbeam near the first crossbeam, and multiple coils are supported on the support portion. The support portion includes multiple sets of support member groups spaced apart along the length direction of the first crossbeam. One coil is supported on one set of support member groups. Each set of support member groups includes two symmetrically arranged support members. The side of each support member near the corresponding coil is adapted to the inner wall of the corresponding coil and can abut against the inner wall of the corresponding coil. The side away from the corresponding coil is fixedly connected to the outer wall of the second crossbeam. The cross section of the second crossbeam perpendicular to its length direction is a regular hexagon.

[0012] Using the above technical solution, one side of each support member is adapted to the inner wall of the coil and can abut against the inner wall of the coil, while the other side is fixedly connected to the outer wall of the second crossbeam. A coil is supported on the outer periphery of the second crossbeam by two support members of a set of support members, which can achieve complete fit between the coil and the side wall of the coil frame, thereby realizing the detachable and fixed connection between the coil to be installed and the side wall of the coil frame, which is convenient and efficient.

[0013] According to another specific embodiment of the present invention, the dynamic assembly device for magnetically pulled single-crystal multi-coil disclosed in this embodiment further includes a first anti-slip part and a second anti-slip part in the hoisting bracket; the first anti-slip part includes a plurality of first anti-slip components spaced apart along the length direction of the second crossbeam, the number of first anti-slip components being the same as the number of coils, and fixedly connected one by one; each first anti-slip component includes two first anti-slip members, each first anti-slip member including a sliding plate and an anti-slip plate that are perpendicular to each other and fixedly connected, the sliding plate being adapted to the inner wall of the corresponding coil and the corresponding support member, the sliding plate being located between the inner wall of the corresponding coil and the support member, and being able to slide relative to the corresponding support member, the anti-slip plate being located on the side of the corresponding coil closer to the first driving mechanism; the second anti-slip part includes a plurality of second anti-slip members spaced apart along the length direction of the second crossbeam, the plurality of second anti-slip members being detachably fixed to the outer wall of the second crossbeam, and each coil having a second anti-slip member on each opposite side along its thickness direction.

[0014] By adopting the above technical solution, the first and second anti-slip parts can be set to prevent the coil from sliding and hitting other adjacent coils, thus avoiding damage caused by coil collision. Furthermore, each of the second anti-slip parts is detachably fixed to the outer wall of the second crossbeam. If it is necessary to move the coil to be installed to the other end of the second crossbeam along the first direction, it is only necessary to remove the second anti-slip part on the side of the coil to be installed away from the side beam.

[0015] According to another specific embodiment of the present invention, the dynamic assembly device for magnetically pulled single-crystal multi-coil disclosed in this embodiment further includes a balancing component, which includes a counterweight and a slider; the counterweight is fixedly connected to the other end of the first crossbeam; the slider is located on the side of the first crossbeam away from the second crossbeam and can slide relative to the first crossbeam along the length direction of the first crossbeam; the lifting part includes a first lifting lug and a second lifting lug, the first lifting lug is fixed above the slider, and the second lifting lug is fixed above the side of the first crossbeam away from the second crossbeam and is spaced apart from the first lifting lug in the length direction of the first crossbeam.

[0016] By adopting the above technical solution and setting counterweights, the lifting support and multiple coils can be kept in a roughly balanced state during the lifting and movement process, that is, the first and second crossbeams remain parallel to the horizontal direction. Since both the first and second lifting lugs are hung on a hook via lifting rods, by setting a first lifting lug that can move along the length of the first crossbeam and a second lifting lug fixed to the first crossbeam, if the center of gravity shifts during the lifting and movement of the lifting support and multiple coils, making it impossible to keep the first and second crossbeams parallel to the horizontal direction, the sliding distance of the first lifting lug along the length of the first crossbeam can be adjusted to adjust the position of the lifting point, thereby adjusting the center of gravity of the lifting support and multiple coils. This ensures that the first and second crossbeams are always parallel to the horizontal direction, that is, the multiple coils supported on the outer periphery of the second crossbeam always remain vertical, improving the stability and safety of the lifting, and facilitating the installation of the vertically positioned coils onto the side wall of the coil frame.

[0017] According to another specific embodiment of the present invention, the dynamic assembly device for a magnetically pulled single-crystal multi-coil disclosed in this embodiment further includes a slide rail and a second driving mechanism in the balancing component. The slide rail is adapted to the slider, fixed on the side of the first crossbeam away from the second crossbeam, and extends along the length direction of the first crossbeam. The slider is slidably connected to the slide rail. The second driving mechanism includes a lead screw, a lead screw bearing seat, and a second driving member. The lead screw bearing seat and the second driving member are fixed on the side of the first crossbeam away from the second crossbeam. One end of the lead screw is rotatably connected to the lead screw bearing seat, and the other end of the lead screw extends along the length direction of the first crossbeam and is drivenly connected to the second driving member through a coupling. The slider is sleeved on the outer circumference of the lead screw and threadedly connected to the lead screw. The second driving member drives the lead screw to rotate, causing the slider and the first lifting lug to slide along the length direction of the first crossbeam.

[0018] Using the above technical solution, the slide rail and lead screw work together to achieve dual-guided transmission for the slider and the first lifting lug, ensuring the straightness and stability of the slider and the first lifting lug as they slide along the length of the first crossbeam, avoiding offset and jamming, and improving the accuracy of lifting point adjustment. The lead screw and nut transmission, in conjunction with the second drive component, achieves automated, stepless, and precise positioning of the first lifting lug, allowing for rapid adjustment of the center of gravity of the lifting bracket and multiple coils, quickly achieving the balance of the lifting bracket and multiple coils, with convenient operation and high adjustment accuracy. The slide rail and the second drive mechanism are both integrated on the side of the first crossbeam away from the second crossbeam, resulting in a compact overall layout. The lead screw transmission has a self-locking characteristic, ensuring the slider and the first lifting lug remain stable after positioning, without slippage or movement, guaranteeing safety during lifting.

[0019] According to another specific embodiment of the present invention, the dynamic assembly device for magnetically pulled single-crystal multi-coil disclosed in this embodiment further includes two biaxial tilt sensors and two plate ring type tension sensors in the balancing component; the two biaxial tilt sensors are fixed on the first crossbeam and are spaced apart along the length direction of the first crossbeam, and are used to measure whether the first crossbeam is in a horizontal state; the two plate ring type tension sensors are rotatably and fixedly connected to the first lifting lug and the second lifting lug respectively, and are used to measure the tension of the first lifting lug and the second lifting lug.

[0020] Using the above technical solution, the tilt angle of the first crossbeam can be obtained through a dual-axis tilt sensor, thereby detecting whether the first crossbeam is in a horizontal state and determining the balance state of the lifting support, preventing coil damage due to the tilt of the first crossbeam. The plate ring type tension sensor can obtain the tension of the first and second lifting lugs, which not only prevents overloading of a single lifting lug and improves lifting safety, but also determines the balance state of the lifting support based on whether the tension of the two lifting lugs is consistent. By setting up two types of sensors, dual monitoring of the horizontal state of the first crossbeam and the consistency of the tension of the two lifting lugs is achieved, improving the accuracy of the balance state judgment of the lifting support, thus making balance state adjustment more precise and efficient.

[0021] According to another specific embodiment of the present invention, the dynamic assembly device for magnetically pulled single-crystal multi-coil disclosed in this embodiment of the present invention further includes a controller, which is fixed on the side beam and electrically connected to two biaxial tilt sensors, two plate ring type tension sensors, a first driving member and a second driving member.

[0022] Using the above technical solution, two dual-axis tilt sensors acquire the tilt angle of the first crossbeam, and two plate-ring tension sensors acquire the tension of the first and second lifting lugs, respectively. The controller can determine whether the lifting support is in a balanced state based on the tilt angle, the tension of the first and second lifting lugs, and so on. If the lifting support is not in a balanced state, the controller activates the second drive unit. The second drive unit drives the lead screw to rotate, causing the slider and the first lifting lug to slide along the length of the first crossbeam, thereby adjusting the position of the first lifting lug, i.e., adjusting the position of the lifting point, to bring the lifting support into a balanced state. Additionally, the controller can also activate the first drive unit, which drives the first bevel gear to rotate, causing the second bevel gear and worm gear to rotate, pushing the contact piece and the coil to be installed to move along the first direction. In this way, by setting the controller, the start and stop of the first and second drive units can be realized, improving the degree of automation of the control.

[0023] This invention also discloses a dynamic assembly method for a magnetically pulled single-crystal multi-coil, performed using the aforementioned dynamic assembly device for magnetically pulled single-crystal multi-coil. The dynamic assembly method includes: S1: Multiple coils are placed vertically on a coil placement frame, spaced apart along the length of the frame. S2: The other end of the second crossbeam of the dynamic assembly device is inserted into the interior of the multiple coils, which are supported on the outer periphery of the second crossbeam and movable along its length. S3: The hoisting bracket, the pushing assembly, and the multiple coils are moved so that the coil to be installed is close to the side wall of the coil frame, and the coil to be installed is the one furthest from the side beam among the multiple coils. S4: The pushing assembly pushes the coil to be installed along the length of the second crossbeam to the other end of the second crossbeam. S5: The coil to be installed is detachably and fixedly connected to the side wall of the coil frame.

[0024] Using the above technical solution, multiple coils are supported on the outer periphery of the second crossbeam. This not only allows for the simultaneous hoisting of multiple coils, but also enables the use of a propulsion component to move the coil furthest from the side beam (i.e., the coil to be installed) along the length of the second crossbeam to one end of the side beam furthest from the second crossbeam. This allows the coil to be installed to directly adhere to the side wall of the coil frame, achieving a safer and more convenient detachable and fixed connection between the coil to be installed and the side wall of the coil frame. Then, a new coil furthest from the side beam is selected as the new coil to be installed, and it is detachably and fixedly connected to the other side wall of the coil frame using the same method. This allows for the installation of multiple coils, improving installation efficiency.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention provides a dynamic assembly device and method for magnetically pulled single-crystal multi-coil assembly. The dynamic assembly device includes a coil placement frame, a lifting bracket, and a propulsion assembly. Multiple coils in a vertical position are placed on the coil placement frame, and the multiple coils are spaced apart along the length of the coil placement frame. The lifting bracket includes a U-shaped lifting device, which includes a first crossbeam and a second crossbeam arranged at relative intervals, as well as side beams. The other end of the second crossbeam of the lifting device, i.e., the open end, is inserted into the interior of the multiple coils, so that the multiple coils are supported on the outer periphery of the second crossbeam. A lifting part for lifting is provided on the side of the first crossbeam away from the second crossbeam. By using the lifting part in conjunction with lifting tools such as a lifting trolley, the multiple coils and the lifting bracket are lifted and moved, realizing the single lifting of multiple coils. The coil furthest from the side beam among multiple coils, i.e., the coil to be installed, is positioned close to the side wall of the coil frame. A pushing assembly, mounted on the second crossbeam, propels the coil to be installed along the length of the second crossbeam until it reaches the end of the crossbeam furthest from the side beam. At this point, the coil can be pressed against the side wall of the coil frame, allowing for a detachable and secure connection. This method provides a safer and more convenient way to detachably and securely connect the coil to the side wall of the coil frame. After the coil to be installed is complete, the new coil furthest from the side beam is selected as the new coil to be installed. The coil and the lifting bracket are moved further, bringing the new coil closer to the other side wall of the coil frame. Following the same method, a detachable and secure connection can be achieved between the new coil and the other side wall of the coil frame. This allows for the installation of multiple coils, improving installation efficiency. Attached Figure Description

[0059] A magnetically pulled single-crystal coil is a high-performance superconducting coil used in magnetically controlled Czochralski (CZ) single-crystal technology, playing a crucial role in fields such as single-crystal silicon production. The magnetically pulled single-crystal coil is designed in a ring shape, and its corresponding support frame lies flat on the ground. The mounting holes are actually parallel to the ground, and the mounting holes suitable for mates with the support frame can only be located on the side of the magnetically pulled single-crystal superconducting coil.

[0060] Currently, the assembly method for magnetically pulled single-crystal coils involves using a crane hoisting device to directly pass the sling through the inner ring of a magnetically pulled single-crystal coil. The two ends of the sling are directly fixed to the hooks of the crane hoisting device. After the magnetically pulled single-crystal superconducting coil is close to the mounting side wall of the support frame, it is then fixed with bolts. This method not only results in unstable installation due to the obstruction of the sling side during installation, preventing the coil from fitting snugly against the mounting side wall, but also allows only one coil to be installed at a time, leading to low installation efficiency.

[0061] To address the aforementioned technical problems, this invention provides a dynamic assembly device for magnetically pulled single-crystal multi-coil systems. The dynamic assembly device includes a coil placement frame, a lifting bracket, and a propulsion assembly. The coil placement frame is used to place multiple coils in a vertical position. The lifting bracket includes a lifting device with a U-shaped structure, comprising a first and second crossbeam arranged at relative intervals and parallel to each other, as well as side beams. The other end of the second crossbeam, i.e., the open end, is inserted into the interior of multiple coils, so that the multiple coils are supported on the outer periphery of the second crossbeam. A lifting part for lifting is provided on the side of the first crossbeam away from the second crossbeam. Through the lifting part in conjunction with a crane lifting device, multiple coils and the lifting bracket are lifted and moved, realizing the single lifting of multiple coils. The coil furthest from the side beam among multiple coils, i.e., the coil to be installed, is positioned close to the side wall of the coil frame. A pushing assembly, mounted on the second crossbeam, propels the coil to be installed along the length of the second crossbeam until it reaches the end of the crossbeam furthest from the side beam. At this point, the coil can be pressed against the side wall of the coil frame, allowing for a detachable and secure connection. This method provides a safer and more convenient way to detachably and securely connect the coil to the side wall of the coil frame. Following this method, other new coils furthest from the side beam can be moved, and these other coils can be detachably and securely connected to the other side wall of the coil frame. This enables dynamic installation of multiple coils, improving installation efficiency.

[0062] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Figure 1As shown, the magnetically pulled single-crystal coil (referred to as coil 10) has a ring-shaped cross-section perpendicular to its thickness direction, meaning the thickness direction of coil 10 is parallel to its axial direction. It should be noted that, as... Figure 1 As shown, each coil 10 has a plurality of coil mounting holes 11 spaced apart along the circumference of the coil 10 on its side wall.

[0065] The dynamic assembly device is used to install the coil 10A to be installed from among a plurality of coils 10 to a position such as Figure 2 The side wall 21 of the coil holder 20 shown. It should be noted that, as... Figure 2 As shown, the side wall 21 of the coil frame 20 is provided with a plurality of coil frame fixing holes 22.

[0066] Multiple coil frame fixing holes 22 and multiple coil mounting holes 11 are one-to-one and compatible. The coil 10A to be installed can be detachably fixed to the side wall 21 of the coil frame 20 through multiple coil mounting holes 11, multiple coil frame fixing holes 22, and multiple fasteners (not shown in the figure). Each fastener passes through the corresponding coil frame fixing hole 22 and is threaded to the corresponding coil mounting hole 11.

[0067] like Figures 3-20 As shown, the dynamic assembly device 30 includes a coil placement rack 100, a hoisting bracket 200, and a propulsion assembly 300.

[0068] Among them, such as Figures 3-5 As shown, the coil placement rack 100 is used to place multiple coils 10 in a vertical position, with the multiple coils 10 extending along the length direction of the coil placement rack 100. Figures 3-5 (X-direction) interval settings.

[0069] It should be noted that "coil 10 is in a vertical position" means that the thickness direction of coil 10 is parallel to the horizontal direction. After coil 10 is placed on coil placement rack 100, the length direction of coil placement rack 100 is parallel to both the horizontal direction and the thickness direction of coil 10. The specific structure of coil placement rack 100 can be described as follows: Figures 3-5 As shown, other structures are also possible, as long as they can accommodate multiple vertically arranged coils 10. This embodiment does not impose specific limitations on this. The coil placement rack 100 can be placed on the ground or on other surfaces parallel to the ground.

[0070] like Figures 6-11 As shown, the hoisting support 200 includes a lifting device 210, which has a U-shaped structure and includes a first crossbeam 211 and a second crossbeam 212 arranged at relatively intervals, as well as side beams 213. The length direction of the first crossbeam 211 and the length direction of the second crossbeam 212 are ( Figure 6 The X-direction of the first crossbeam 211 is parallel to each other, and one end of the first crossbeam 211 (e.g.) Figure 6 The right end of the middle) and one end of the second crossbeam 212 (e.g. Figure 6 The right end of the first crossbeam 211 is fixedly connected via the side beam 213, and the other end of the first crossbeam 211 (e.g.) Figure 6 (left end of the middle) and the other end of the second crossbeam 212 (e.g.) Figure 6 The left end of the middle) forms a U-shaped opening. For example... Figure 6 and Figure 7 As shown, a lifting section 220 for hoisting is provided on the side of the first crossbeam 211 away from the second crossbeam 212. It should be noted that the lifting section 220 needs to cooperate with the hook of the overhead crane hoisting device to hoist the coil 10. The length direction of the first crossbeam 211 is parallel to the length direction of the coil placement frame 100.

[0071] like Figure 3 and Figure 4 As shown, the other end of the second crossbeam 212 (i.e., the open end, for example) Figure 3 The left end of the coil 10 is used to insert multiple coils 10 into the interior. The multiple coils 10 are supported on the outer periphery of the second crossbeam 212 and can move along the length direction of the second crossbeam 212. The thickness direction of the coil 10, the length direction of the coil placement rack 100, and the length direction of the second crossbeam 212 are parallel to each other.

[0072] It should be noted that, in this embodiment, the specific number of coils 10 supported on the outer periphery of the second crossbeam 212 can be determined according to the load-bearing capacity of the dynamic assembly device 30. For example, it can be 3 coils, or it can be as follows: Figure 3 The diagram shows four coils, but more are possible. A support structure can be provided on the outer periphery of the second crossbeam 212 to support multiple coils 10. The support structure can be ring-shaped or other shapes, as long as one end is fixed to the second crossbeam 212, the other end is adapted to and supported on the inner wall of each coil 10, and the movement of each coil 10 along the length of the second crossbeam 212 is not restricted.

[0073] like Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the propulsion assembly 300 is mounted on the second crossbeam 212 and can push the coil 10A to be installed to move along the length of the second crossbeam 212. When the coil 10A to be installed moves to the other end of the second crossbeam 212 (e.g., ...), ... Figure 3 When the coil to be installed (at the left end of the coil frame 20) is at the left end, the coil 10A to be installed can be detachably fixed to the side wall 21 of the coil frame 20. The coil 10A to be installed is the coil 10 furthest from the side beam 213 among the multiple coils 10.

[0074] It should be noted that the propulsion assembly 300 can be a component consisting of a push rod, a worm gear, and a drive motor. One side of the push rod is detachably and fixedly connected to the coil 10A to be installed, and the other side is detachably and fixedly connected to the worm gear. The worm gear is driven by the drive motor, which drives the worm gear to rotate, thereby moving the push rod and the coil 10A to be installed along the length direction of the second crossbeam 212. Alternatively, the propulsion assembly 300 can be a component consisting of a telescopic member and a drive motor. The telescopic member is fixed to the second crossbeam 212, with one end detachably and fixedly connected to the coil 10A to be installed, and the other end driven by the drive motor. The drive motor drives the telescopic member to extend along the length direction of the second crossbeam 212, thereby pushing the coil 10A to be installed along the length direction of the second crossbeam 212. The propulsion assembly 300 can also have other structures, as long as they can push the coil 10A to be installed along the length direction of the second crossbeam 212.

[0075] It should be further explained that a coil frame through hole 23 is provided on the side wall 21 of the coil frame 20. When the coil 10A to be installed moves to the other end of the second crossbeam 212, that is, the end of the second crossbeam 212 away from the side beam 213 (i.e., the open end of the second crossbeam 212), the second crossbeam 212 can be inserted into the coil frame through hole 23, so that the side of the coil 10A to be installed away from the side beam 213 is close to the side wall 21 of the coil frame 20, and the multiple coil frame fixing holes 22 of the side wall 21 correspond one-to-one with the multiple coil mounting holes 11 of the coil 10A to be installed. Each fastener passes through the corresponding coil frame fixing hole 22 and is threadedly connected to the corresponding coil mounting hole 11 to achieve the threaded connection between the coil 10A to be installed and the side wall 21 of the coil frame 20.

[0076] The specific assembly process of an assembly method based on this dynamic assembly device is as follows: First, multiple coils 10 in a vertical state are spaced apart along the length of the coil placement frame 100, and the hoisting trolley cooperates with the hoisting part 220; then, the other end of the second crossbeam 212 of the lifting device 210, i.e., the open end of the second crossbeam 212, is inserted into the interior of the multiple coils 10, and the hoisting part 220 is slowly lifted so that the multiple coils 10 are supported on the outer periphery of the second crossbeam 212; the hoisting part 220 is continued to be lifted, and the multiple coils 10 and the hoisting bracket 210 are moved. 00, so that the coil 10 furthest from the side beam 213 among the multiple coils 10, i.e. the coil to be installed 10A, is brought close to the side wall 21 of the coil frame 20; the coil to be installed 10A is pushed along the length direction of the second crossbeam 212 by the push assembly 300, and the coil to be installed 10A is moved to the end of the second crossbeam 212 away from the side beam 213. At this time, the side of the coil to be installed 10A away from the side beam 213 can be pressed against the side wall 21 of the coil frame 20; so that the coil to be installed 10A is detachably fixed to the side wall 21 of the coil frame 20. Then, the remaining coils 10 and the lifting bracket 200 are moved. The coil 10 furthest from the side beam 213 among the remaining coils 10 is selected as the new coil to be installed. The new coil to be installed is brought close to the other side wall 21 of the coil frame 20. The new coil to be installed is pushed along the length of the second crossbeam 212 by the pushing component 300, so that the new coil to be installed is moved to the end of the second crossbeam 212 furthest from the side beam 213. By continuing to follow the above method, the new coil to be installed can be detachably fixed to the other side wall 21 of the coil frame 20. In this way, multiple coils 10 can be lifted at a time. When each coil 10 is fixed to the corresponding side wall 21 of the coil frame 20, the coil 10 is supported on the outer periphery of the second cross beam 212. This allows the side of the coil 10 furthest from the side beam 213 to be close to the side wall 21 of the coil frame 20, which can achieve a safer and more convenient fixed connection between the coil 10 and the side wall 21 of the coil frame 20. In addition, a propulsion component 300 is provided, which can push the coil 10 furthest from the side beam 213 to move along the length direction of the second crossbeam 212 each time, thereby enabling the dynamic installation of multiple coils 10 and improving installation efficiency.

[0077] In one embodiment of the present invention, such as Figure 8 , Figure 9 and Figure 11 As shown, the second crossbeam 212 has a through hole 2121 extending along its length, and a slot 2122 extending along its length is provided on one side of the second crossbeam 212, the slot 2122 communicating with the through hole 2121. Figures 10-12 As shown, the propulsion assembly 300 includes an abutment member 310, a propulsion member 320, and a first drive mechanism 330; the first drive mechanism 330 is mounted on the side beam 213, and the propulsion member 320 is located inside the through hole 2121, with one end (e.g.) Figure 11The right end of the first drive mechanism 330 is connected to the output end of the first drive mechanism 330, and the other end (e.g.) is connected to the output end of the first drive mechanism 330. Figure 11 The left end of the second crossbeam 212 extends along its length to the other end of the second crossbeam 212 (i.e., the left end of the second crossbeam 212). Figure 12 (Left end of the second crossbeam 212); the abutment 310 is adapted to and engages with the slot 2122, so that the abutment 310 moves only along the length of the second crossbeam 212 within the slot 2122; the abutment 310 is connected to the pusher 320 in a transmission manner; if the abutment 310 is located on the side of the coil 10A to be installed close to the first drive mechanism 330, the first drive mechanism 330 drives the pusher 320, causing the abutment 310 to move along the first direction. After the abutment 310 abuts against the coil 10A to be installed, it pushes the coil 10A to be installed to move along the first direction, which can move the coil 10A to the other end of the second crossbeam 212; if Figure 11 As shown, the first direction (Y direction) is the direction from one end of the second crossbeam 212 to the other end.

[0078] It should be noted that the first drive mechanism 330 includes drive devices such as a motor, hydraulic device, and pneumatic device. The propulsion member 320 can be a worm gear, a telescopic rod, or other structure capable of driving the contact member 310 and the coil 10A to be installed to move along the first direction. If the propulsion member 320 is a worm gear, the first drive mechanism 330 drives the worm gear to rotate, thereby driving the contact member 310 and the coil 10A to be installed to move along the first direction. If the propulsion member 320 is a telescopic rod, the first drive mechanism 330 drives the telescopic rod to extend along the first direction, thereby driving the contact member 310 and the coil 10A to be installed to move along the first direction.

[0079] It should be further explained that the first drive mechanism 330 drives the pusher 320, which in turn moves the abutment 310 along the first direction until it abuts the coil to be installed 10A. This allows the abutment 310 to be detachably and fixedly connected to the coil to be installed 10A, forming a rigid linkage that ensures the accuracy of the movement of the coil to be installed 10A along the first direction. If the abutment 310 is detachably and fixedly connected to the coil to be installed 10A, and the coil to be installed 10A is detachably and fixedly connected to the side wall 21 of the coil frame 20, the abutment 310 needs to be disassembled.

[0080] In one embodiment of the present invention, such as Figures 11-13 As shown, the propulsion component 320 is a worm gear. (As indicated...) Figures 14-16 As shown, the first drive mechanism 330 includes a first drive member 331, a first bevel gear 332, and a second bevel gear 333; the first drive member 331 is fixed to the side beam 213, and the output shaft of the first drive member 331 is connected to the first bevel gear 332 in a transmission manner, as shown. Figure 15As shown, the first bevel gear 332 and the second bevel gear 333 are perpendicular and mesh with each other, and the second bevel gear 333 is fixedly connected to one end of the worm. Figure 12 and Figure 17 As shown, the abutment 310 has a groove 311 adapted to the worm on the side near the worm, and is engaged with the outer wall of the worm through the groove 311.

[0081] Specifically, by setting a first drive mechanism 330 including a first drive member 331, a first bevel gear 332, and a second bevel gear 333, with the first bevel gear 332 and the second bevel gear 333 being perpendicular and meshing with each other, a 90° reversal of power can be achieved through a simple structure, avoiding conflict between the output shaft of the first drive member 331 and the extension direction of the propulsion member 320, making the layout more compact.

[0082] It should be noted that the first driving component 331 is the first driving motor. The propulsion assembly 300 also includes two worm gear cover plates, which are respectively fixed to both ends of the through hole 2121 of the second crossbeam 212. The fixed connection method of each worm gear cover and the second crossbeam 212 includes, but is not limited to, threaded connection, snap-fit, etc. The propulsion component 320, i.e., one end of the worm, passes through the worm gear cover plate and is fixedly connected to the second bevel gear 333.

[0083] In one embodiment of the present invention, such as Figure 12 and Figure 17 As shown, limit protrusions 312 are provided on both opposite sides of the abutment member 310, such as... Figure 8 and Figure 9 As shown, the opposite side walls of the slot 2122 are provided with limiting grooves 2123 that are adapted to the limiting protrusions 312. The limiting grooves 2123 extend along the length of the second crossbeam 212. The abutting member 310 is engaged with the slot 2122 through the limiting protrusions 312 and the corresponding limiting grooves 2123, so that the abutting member 310 can only move along the length of the second crossbeam 212.

[0084] Specifically, the abutment 310 achieves unidirectional movement constraint only along the length direction of the second crossbeam 212 through the snap-fit ​​cooperation of the double-sided limiting protrusions 312 and the double-sided limiting grooves 2123 of the slot 2122, thereby avoiding the coil 10 from being pushed off-center.

[0085] In one embodiment of the present invention, such as Figure 8 , Figure 9 and Figure 11 As shown, the slot 2122 is provided with a plurality of snap-in portions 2124 adapted to the abutment member 310. The abutment member 310 can be snapped into the slot 2122 and into the outer wall of the worm gear through any one of the snap-in portions 2124.

[0086] It should be noted that each coil 10 on the slot 2122 is provided with at least one engaging portion 2124 on the side near the first drive mechanism 330. The number of engaging portions 2124 can be the same as or more than the number of coils 10, to ensure that the abutment 310 can push each of the multiple coils 10 supported on the outer periphery of the second crossbeam 212.

[0087] Specifically, the multiple insertion parts 2124 enable the adjustment of the position of the abutment 310 and the slot 2122. Only one abutment 310 is needed. By adjusting the position, multiple coils 10 at different positions can be pushed, thus improving versatility.

[0088] Specifically, if the abutment 310 engages with the slot 2122 from a snap-in portion 2124 on the side of the coil 10A to be installed near the first drive mechanism 330, and the abutment 310 engages with the slot 2122 from the snap-in portion 2124 on the right side of the coil 10A to be installed, the first drive member 331 drives the first bevel gear 332 to rotate, thereby driving the second bevel gear 333 and the worm to rotate, and pushing the abutment 310 and the coil 10A to be installed to move along the first direction.

[0089] In one embodiment of the present invention, such as Figure 6 , Figure 7 , Figure 11 , Figure 14 and Figure 16 As shown, the lifting bracket 200 also includes a support portion 230, which is fixed to the outer wall of the second crossbeam 212 near the first crossbeam 211, i.e., the support portion 230 is fixed to the top of the second crossbeam 212. Multiple coils 10 are supported by the support portion 230. The support portion 230 includes multiple sets of support members spaced apart along the length of the first crossbeam 211. One coil 10 is supported by one set of support members. Each set of support members includes two symmetrically arranged support members 231. The side of each support member 231 near the corresponding coil 10 is adapted to the inner wall of the corresponding coil 10 and can abut against the inner wall of the corresponding coil 10. The side away from the corresponding coil 10 is fixedly connected to the outer wall of the second crossbeam 212. The cross section of the second crossbeam 212 perpendicular to its length is a regular hexagon, i.e., the second crossbeam 212 is a hexagonal tube. Specifically, the first crossbeam 211 and the side beams 213 are both I-beams, ensuring the reliability of the lifting device 210.

[0090] like Figure 14 and Figure 18As shown, each support member 231 is I-shaped, including an abutment plate 2311, a connecting plate 2312, and a fixing plate 2313. Specifically, the connecting plate 2312 extends radially along the coil 10. The abutment plate 2311 and the fixing plate 2313 are respectively fixed to both ends of the connecting plate 2312. The abutment plate 2311 is adapted to the inner wall of the coil 10 and can abut against the inner wall of the coil 10. The connecting plate 2312 is adapted to the outer wall of the second crossbeam 212 and is detachably fixedly connected to the outer wall of the second crossbeam 212. In one specific embodiment, the connecting plate 2312 and the outer wall of the second crossbeam 212 are threadedly connected.

[0091] It should be noted that the fixing connection methods of the abutment plate 2311, fixing plate 2313, and connecting plate 2312 include, but are not limited to, integral molding, welding, and threaded connection. Each coil 10 can move relative to the support part 230 along the length direction of the second crossbeam 212. The number of multiple sets of support components can be set according to actual needs, for example... Figure 14 As shown, three sets of support components can be set, that is, six support components 231 are set.

[0092] In one embodiment of the present invention, such as Figure 6 , Figure 7 , Figure 10 , Figure 11 , Figure 14 and Figure 16 As shown, the hoisting bracket 200 also includes a first anti-slip part 240 and a second anti-slip part 250; the first anti-slip part 240 includes a plurality of first anti-slip components spaced apart along the length direction of the second crossbeam 212, the number of first anti-slip components being the same as the number of coils 10, and each being fixedly connected. Each first anti-slip component includes two first anti-slip parts 241, such as... Figure 19 As shown, each first anti-slip component 241 includes a sliding plate 2411 and an anti-slip plate 2412 that are perpendicular to each other and fixedly connected.

[0093] The slide plate 2411 is adapted to the inner wall of the corresponding coil 10 and the corresponding support member 231. The slide plate 2411 is located between the inner wall of the corresponding coil 10 and the corresponding support member 231 and can slide relative to the support member 231. The stop slide plate 2412 is located on the side of the corresponding coil 10 near the first drive mechanism 330.

[0094] Specifically, each first anti-slip member 241 is detachably and fixedly connected to the corresponding coil 10. This detachable connection includes, but is not limited to, threaded connections and adhesive bonding for easy disassembly. Each first anti-slip member 241 can be a sliding plate 2411 detachably and fixedly connected to the corresponding coil 10, or an anti-slip plate 2412 detachably and fixedly connected to the corresponding coil 10, or both sliding plate 2411 and anti-slip plate 2412 can be detachably and fixedly connected to the corresponding coil 10. The second anti-slip portion 250 includes a plurality of second anti-slip members 251 spaced apart along the length of the second crossbeam 212. These second anti-slip members 251 are detachably fixed to the outer wall of the second crossbeam 212. Each coil 10 has one second anti-slip member 251 on each opposite side along its thickness direction.

[0095] Specifically, by setting the first anti-slip part 240 and the second anti-slip part 250, it is possible to prevent each coil 10 from sliding and hitting other adjacent coils 10, thus avoiding collisions between coils 10 and causing damage.

[0096] It should be noted that each of the second anti-slip components 251 is detachably fixed to the outer wall of the second crossbeam 212. If it is necessary to move the coil to be installed 10A along the first direction to the end of the second crossbeam 212 away from the side beam 213, it is only necessary to remove the second anti-slip component 251 on the side of the coil to be installed away from the side beam 213. Then, the first drive mechanism 330 drives the worm gear to rotate, causing the abutment component 310 to move along the first direction. After the abutment component 310 abuts against the coil to be installed 10A, it further drives the abutment component 310, the coil to be installed 10A, and the corresponding first anti-slip component 241 together to move along the first direction relative to the corresponding two support components 231. Additionally, after or during the detachable fixed connection between the coil to be installed 10A and the side wall 21 of the coil frame 20, it is necessary to remove the second anti-slip component 251 corresponding to the coil to be installed 10A. Figure 16 A schematic diagram is shown showing the structure with the second anti-slip component 251 on the left side of the coil 10A to be installed removed.

[0097] In one embodiment of the present invention, such as Figure 6 , Figure 7 and Figure 20 As shown, the dynamic assembly device 30 also includes a balancing component 400, which includes a counterweight 410 and a slider 420; the counterweight 410 is detachably fixedly connected to the other end of the first crossbeam 211, that is, the end of the first crossbeam 211 away from the side beam 213, for example... Figure 6 , Figure 7 and Figure 20The left end of the first crossbeam 211 is shown; the slider 420 is located on the side of the first crossbeam 211 away from the second crossbeam 212 and can slide relative to the first crossbeam 211 along the length direction of the first crossbeam 211; the lifting part 220 includes a first lifting lug 221 and a second lifting lug 222. The first lifting lug 221 is fixed above the slider 420, and the second lifting lug 222 is fixed above the side of the first crossbeam 211 away from the second crossbeam 212 and is spaced apart from the first lifting lug 221 along the length direction of the first crossbeam 211.

[0098] It should be noted that the first lifting lug 221 and the second lifting lug 222 of the lifting unit 220 need to be used in conjunction with the overhead crane lifting device for lifting. The overhead crane lifting device generally includes a hook and two lifting rods. One end of each lifting rod is hung on the hook, and the other end is connected to the first lifting lug 221 and the second lifting lug 222 respectively, forming a triangular lifting structure together with the first crossbeam 211. The specific weight of the counterweight 410 needs to be determined based on the weight of the lifting bracket 200 and the multiple coils 10 supported on the outer periphery of the second crossbeam 212, to ensure that the lifting bracket 200 always remains in a balanced state, that is, the length direction of the first crossbeam 211 and the length direction of the second crossbeam 212 are both parallel to the horizontal direction, and the multiple coils 10 are always in a vertical state. The slider 420 and the first lifting lug 221 can be as follows: Figure 20 As shown, the second lifting lug 222 is located to the left of the first crossbeam 211, or it can be located to the right of the first crossbeam 211. This embodiment does not impose specific restrictions on this, as long as the second lifting lug 222 and the first lifting lug 221 are spaced apart in the length direction of the first crossbeam 211.

[0099] Specifically, the first lifting lug 221 can slide and cooperate with the second lifting lug 222, which is fixedly connected to the first crossbeam 211, to achieve adjustable lifting point position, thereby adjusting the center of gravity of the lifting bracket 200 and multiple coils 10. This ensures that the first crossbeam 211 and the second crossbeam 212 are always parallel to the horizontal direction, that is, the lifting bracket 200 always maintains a balanced state and the multiple coils 10 supported on the outer periphery of the second crossbeam 212 always maintain a vertical state, improving the stability and safety of the lifting, and facilitating the installation of the vertically positioned coils 10 onto the side wall 21 of the coil frame 20.

[0100] In one embodiment of the present invention, such as Figure 20As shown, the balancing assembly 400 also includes a slide rail 430 and a second drive mechanism 440. The slide rail 430 is adapted to the slider 420, fixed to the side of the first crossbeam 211 away from the second crossbeam 212, and extends along the length direction of the first crossbeam 211. The slider 420 is slidably connected to the slide rail 430. The second drive mechanism 440 includes a lead screw 441, a lead screw bearing seat 442, and a second drive member 443. The lead screw bearing seat 442 and the second drive member 443 are fixed to the side of the first crossbeam 211 away from the second crossbeam 212. One end of the lead screw 441 is rotatably connected to the lead screw bearing seat 442, and the other end of the lead screw 441 extends along the length direction of the first crossbeam 211 and is connected to the second drive member 443 via a coupling. The slider 420 is sleeved on the outer periphery of the lead screw 441 and threadedly connected to the lead screw 441. The second drive member 443 drives the lead screw 441 to rotate, causing the slider 420 and the first lifting lug 221 to slide along the length direction of the first crossbeam 211.

[0101] It should be noted that the second driving component 443 is a second driving motor, used to drive the lead screw 441 to rotate. In this embodiment, the number of slide rails 430 can be one, or it can be as follows: Figure 20 The two shown can be replaced with more, depending on the actual situation. This embodiment does not impose specific limitations on this. The slider 420 has a slider through-hole with an internal thread that matches the external thread of the lead screw 441. Specifically, the slide rail 430 and the lead screw 441 cooperate to achieve dual-guided transmission between the slider 420 and the first lifting lug 221, ensuring the straightness and stability of the slider 420 and the first lifting lug 221 sliding along the length of the first crossbeam 211, avoiding offset and jamming, and improving the accuracy of lifting point adjustment. The lead screw 441 and nut drive, in conjunction with the second drive component 443, achieve automated, stepless, and precise positioning of the first lifting lug 221, quickly adjusting the center of gravity of the lifting bracket 200 and multiple coils 10, and rapidly adjusting the balance of the lifting bracket 200 and multiple coils 10. Operation is convenient and adjustment accuracy is high. The slide rail 430 and the second drive mechanism 440 are both integrated on the side of the first crossbeam 211 away from the second crossbeam 212, resulting in a compact overall layout. The lead screw 441 transmission has a self-locking characteristic. After adjustment, the slider 420 and the first lifting lug 221 are in a stable position without slippage or movement, ensuring that the lifting point position is constant and the force is stable during lifting, thereby ensuring the safety of lifting.

[0102] In one embodiment of the present invention, such as Figure 6 , Figure 7 and Figure 20As shown, the balancing assembly 400 also includes two biaxial tilt sensors 450 and two plate ring type tension sensors 460; the two biaxial tilt sensors 450 are fixed on the first crossbeam 211 and are spaced apart along the length of the first crossbeam 211, and are used to measure whether the first crossbeam 211 is in a horizontal state; the two plate ring type tension sensors 460 are rotatably and fixedly connected to the first lifting lug 221 and the second lifting lug 222 respectively, and are used to measure the tension of the first lifting lug 221 and the second lifting lug 222.

[0103] It should be noted that the dual-axis tilt sensor 450 typically employs microelectromechanical systems (MEMS) technology, converting changes in the static gravitational field into tilt angle changes. Its internal sensing element detects the components of gravitational acceleration along two vertical axes, and then a signal processing circuit converts these components into corresponding tilt angle values. The plate-ring type tension sensor 460's elastic body undergoes elastic deformation under external force, causing the resistance strain gauge attached to its surface to deform accordingly. After deformation, the resistance of the strain gauge changes, and this change in resistance is converted into an electrical signal by a corresponding measurement circuit, thus completing the process of converting external force into an electrical signal. By adjusting its structural dimensions, the plate-ring type tension sensor 460 can meet measurement needs ranging from micro-forces of 0.1 kg to industrial loads of thousands of tons.

[0104] It should be further explained that the two biaxial tilt sensors 450 are arranged at intervals to obtain the tilt angle of the first crossbeam 211, which can accurately detect the horizontal state of the first crossbeam 211, that is, determine the balance state of the entire lifting bracket 200 and whether the lifting posture of the lifting bracket 200 is balanced, that is, whether the multiple coils 10 supported on the outer periphery of the second crossbeam 212 are in a vertical state. Specifically, if the absolute value of the tilt angle of the first crossbeam 211 detected by the two biaxial tilt sensors 450 is less than a preset angle, it is determined that the first crossbeam 211 is in a horizontal state; otherwise, it is determined that the first crossbeam 211 is not in a horizontal state. The preset angle can be set as needed. In one specific embodiment, the preset angle is 5°. One end of each of the two plate ring type tension sensors 460 is fixed to a hook of the crane lifting device by two tie rods, and the other end is rotatably and fixedly connected to the first lifting lug 221 and the second lifting lug 222 by two axle pins. Two plate-ring type tension sensors 460 detect the tension of the double lifting lugs one-to-one, which can also accurately detect the balance state of the lifting bracket 200, that is, whether the multiple coils 10 supported on the outer periphery of the second crossbeam 212 are in a vertical state. Specifically, if the two plate-ring type tension sensors 460 detect that the tension difference between the first lifting lug 221 and the second lifting lug 222 is less than a preset tension, it is determined that the tension of the first lifting lug 221 and the second lifting lug 222 is similar, and the lifting bracket 200 is in a balanced state; otherwise, it is determined that the lifting bracket 200 is not in a balanced state. The preset tension can be set as needed. In one specific embodiment, the preset tension is 20N. By using two types of sensors for collaborative monitoring, accurate detection of the balance state of the lifting bracket 200, i.e., the vertical state of the coils 10, is achieved. It can also provide reliable data support for the movement position of the first lifting lug 221, thereby improving the safety of the lifting operation.

[0105] In one embodiment of the present invention, such as Figures 6-11 and Figure 20 As shown, the dynamic assembly device 30 also includes a controller 500, which is fixed on the side beam 213 and electrically connected to two dual-axis tilt sensors 450, two plate ring tension sensors 460, a first drive member 331, and a second drive member 443.

[0106] Specifically, two dual-axis tilt sensors 450 acquire the tilt angle of the first crossbeam 211, and two plate-ring type tension sensors 460 acquire the tension of the two lifting lugs respectively. The controller 500 can determine whether the lifting bracket 200 is in a balanced state based on the tilt angle and the tension of the two lifting lugs. If it is determined that the lifting bracket 200 is not in a balanced state, the controller 500 activates the second drive component 443. The second drive component 443 drives the lead screw 441 to rotate, causing the slider 420 and the first lifting lug 221 to slide along the length direction of the first crossbeam 211, adjusting the position of the first lifting lug 221, that is, adjusting the position of the lifting point, thereby adjusting the center of gravity of the lifting bracket 200 and the multiple coils 10, so that the lifting bracket 200 is in a balanced state. In addition, the controller 500 can activate the first drive component 331, which drives the first bevel gear 332 to rotate, driving the second bevel gear 333 and the pusher component 320, that is, the worm gear, to rotate, pushing the abutment component 310 and the coil 10A to be installed to move along the first direction. By setting the controller 500, the start and stop of the first drive unit 331 and the second drive unit 443 can be realized, thereby improving the degree of automation of the control.

[0107] It should be noted that the dynamic assembly device 30 may also include a touch screen display. The touch screen display and the controller 500 are integrated into a control box, which is connected to an external power supply. The controller 500 stores the control program, and the touch screen display is used to display the control program. Before installation, it is necessary to test whether each sensor and motor can start normally, and whether the control program displayed on the touch screen can operate normally.

[0108] In one embodiment of the present invention, such as Figures 7-11 and Figure 20 As shown, the hoisting bracket 200 also includes a first fixing plate 260 and a second fixing plate 270, with the first fixing plate 260 fixed to the side of the first crossbeam 211 away from the second crossbeam 212. Figure 7 and Figure 20 As shown, the first fixing plate 260 fixes the upper side of the first crossbeam 211, and the slide rail 430 and the second drive mechanism 440 are fixed on the first fixing plate 260; the second fixing plate 270 is fixed on the side beam 213, and the controller 500 and the first drive component 331 are fixed on the second fixing plate 270.

[0109] It should be noted that the size of the first fixing plate 260 is larger than the side dimension of the first crossbeam 211 away from the second crossbeam 212, which facilitates fixing the slide rail 430 and the second drive mechanism 440. The size of the second fixing plate 270 is larger than the side dimension of the side beam 213 away from the first crossbeam 211, which facilitates fixing the controller 500 and the first drive component 331.

[0110] The specific assembly process of another assembly method based on this dynamic assembly device is as follows:

[0111] First, multiple vertical coils 10 are spaced apart along the length of the coil placement frame 100, and each first anti-slip component 241 is fixed on the corresponding coil 10. The hoisting trolley and the hoisting unit 220 cooperate to ensure the safety of subsequent hoisting.

[0112] Second, insert the other end of the second crossbeam 212 of the lifting device 210, i.e. the open end, into the interior of the multiple coils 10, fix each second anti-slip member 251 to the outer wall of the second crossbeam 212, and ensure that each coil 10 is provided with a second anti-slip member 251 on both sides along its thickness direction to further ensure the safety of subsequent lifting. Then, slowly lift the lifting part 220 so that the multiple coils 10 are supported on the outer periphery of the second crossbeam 212.

[0113] Third, continue to lift the hoisting unit 220, move the multiple coils 10 and the hoisting bracket 200, so that the coil 10 furthest from the side beam 213, i.e., the coil 10A to be installed, is close to the side wall 21 of the coil frame 20. It should be noted that during the movement, the hoisting bracket 200 is always in a balanced state (the first crossbeam 211 is always parallel to the horizontal direction). Once the hoisting bracket 200 is not in a balanced state, the center of gravity of the hoisting bracket 200 and the multiple coils 10 is adjusted. The adjustment method is as follows: the second drive member 443 drives the lead screw 441 to rotate, which drives the slider 420 and the first lifting lug 221 to slide along the length direction of the first crossbeam 211, and adjusts the distance between the first lifting lug 221 and the second lifting lug 222 until the hoisting bracket 200 is in a balanced state.

[0114] Fourth, the abutment 310 is inserted into the slot 2122 from a snap-in portion 2124 on the side of the coil 10A to be installed near the first drive mechanism 330, and engages with the slot 2122 and the outer wall of the pusher 320 (i.e., the worm). After the second anti-slip member 251 on the side of the coil 10A to be installed away from the first drive mechanism 330 is removed, the first drive member 331 drives the first bevel gear 332 to rotate, which in turn drives the second bevel gear 333 and the worm to rotate, pushing the abutment 310 to move along the first direction. After receiving the coil 10A to be installed, further push the coil 10A to be installed along the first direction, so that the coil 10A to be installed moves to the end of the second crossbeam 212 away from the side beam 213. At this time, the side of the coil 10A to be installed away from the side beam 213 is close to the side wall 21 of the coil frame 20. It should be noted that during the movement of the abutment 310 and the coil 10A to be installed, the hoisting bracket 200 also needs to be in a balanced state at all times. If the hoisting bracket 200 is not in a balanced state, the center of gravity can be adjusted according to the above method.

[0115] Fifth, the coil to be installed 10A is detachably and fixedly connected to the side wall 21 of the coil frame 20 through multiple coil mounting holes 11, multiple coil bracket fixing holes 22, and multiple fasteners; and the first anti-slip member 241 on the coil to be installed 10A is removed, completing the assembly of the coil to be installed 10A to the side wall 21 of the coil frame 20. Then, another coil 10 can be installed using the above method, thereby achieving dynamic installation of multiple coils 10 and improving installation efficiency.

[0116] Example 2

[0117] The present invention also provides a dynamic assembly method for a magnetically pulled single-crystal multi-coil, which is executed based on the dynamic assembly device for the magnetically pulled single-crystal multi-coil in Example 1. The dynamic assembly method includes:

[0118] S1: Multiple coils are placed vertically on a coil holder, spaced apart along the length of the holder. It should be noted that the thickness of the coils is parallel to the length of the coil holder.

[0119] S2: Insert the other end of the second crossbeam of the dynamic assembly device into the interior of multiple coils. The multiple coils are supported on the outer periphery of the second crossbeam and can move along the length of the second crossbeam. Specifically, the other end of the second crossbeam is the end of the second crossbeam away from the side beam, and is also the open end of the second crossbeam.

[0120] S3: Move the hoisting bracket, the propulsion assembly, and multiple coils to bring the coil to be installed closer to the side wall of the coil frame. The coil to be installed is the one furthest from the side beam among the multiple coils.

[0121] S4: The coil to be installed is moved along the length of the second crossbeam by the propulsion component, so that the coil to be installed is moved to the other end of the second crossbeam.

[0122] It should be noted that the specific structure of the propulsion component has been described in Embodiment 1, and will not be repeated in this embodiment. After the coil to be installed is moved to the other end of the second crossbeam, the side of the coil to be installed away from the side beam can be attached to the side wall of the coil frame.

[0123] S5: The coil to be installed is detachably and securely connected to the side wall of the coil holder.

[0124] It should be noted that the coil can be detachably and fixedly connected to the side wall of the coil frame through multiple coil mounting holes, multiple coil frame fixing holes, and multiple fasteners. The specific structure of the multiple coil mounting holes and multiple coil frame fixing holes has been described in Embodiment 1, and will not be repeated in this embodiment.

[0125] Using the above technical solution, multiple coils are supported on the outer periphery of the second crossbeam. This not only allows for the simultaneous hoisting of multiple coils, but also enables the use of a propulsion component to move the coil furthest from the side beam (i.e., the coil to be installed) along the length of the second crossbeam to one end of the side beam furthest from the side beam. This allows the coil to be installed to directly adhere to the side wall of the coil frame, achieving a safer and more convenient detachable and fixed connection between the coil to be installed and the side wall of the coil frame. Then, a new coil furthest from the side beam is selected as the new coil to be installed, and the new coil is detachably and fixedly connected to the other side wall of the coil frame using the same method. This enables dynamic installation of multiple coils, improving installation efficiency.
