Description

Technical Field

[0001] This invention belongs to the field of transportation technology, and specifically relates to a transformer transportation device. Background Technology

[0002] Large transformers are heavy and bulky, and transportation is restricted by factors such as height restrictions and the load-bearing capacity of roads and bridges. Therefore, they are usually disassembled into multiple components before transportation to reduce weight, volume, and transportation difficulty. Each transformer component is transported separately after disassembly and then reassembled on site.

[0003] In the existing technology, the coil assembly disassembled from the transformer cannot be disassembled as a whole, otherwise the coil cannot be properly assembled on site due to the rudimentary assembly conditions. As the core component of the transformer, the disassembled coil assembly is fixed to the transport vehicle by means of fixed ropes or other structures during transportation, or a buffer device is set under the coil to reduce the impact of bumpy road conditions on the coil.

[0004] However, when the transport vehicle accelerates or decelerates, the coil assembly experiences a horizontal acceleration. Existing buffer devices, connected to the coil assembly's support, typically use components like a first spring to restrict the support's movement. While this achieves a buffering effect, the coil wound around the support is made of copper wire wound in turns and is not rigidly connected to the support. After the support's movement is restricted by the buffer device, the coil's acceleration differs from the support's. That is, even as the support gradually decelerates, the coil still retains forward inertial force, causing it to slip relative to the support. This leads to problems such as coil twisting and deformation. The copper wire at the bottom of the coil is particularly affected, as it is subjected to concentrated pressure from the entire coil and is located on the support, resulting in even greater twisting and deformation, impacting subsequent installation and use.

[0005] A search revealed Chinese patent application number 201920662933.5, which discloses a transformer transport device, including a transport cabinet. A base plate is fixedly connected to the bottom of the transport cabinet. Clamping frames are slidably connected to both sides of the bottom inner wall of the transport cabinet. Horizontally threaded screws are installed on both sides of the transport cabinet. One end of each screw is fixedly connected to a push plate inside the transport cabinet, with one side of the push plate contacting the clamping frames. A protective cover is installed on the top of the transport cabinet. Baffles are fixedly connected to both sides of the protective cover. Insert rods are symmetrically fixedly connected to the bottom of each baffle. Sleeves matching the insert rods are fixedly connected to the top of both sides of the transport cabinet. A fastening nut is threaded through the sleeve at the bottom of each insert rod. A vertical rod is fixedly connected to the top of each baffle. An anti-slip block is fixedly connected to the top of each vertical rod. Inserts matching the vertical rods are fixedly connected to both sides of the base plate. This invention can stably clamp transformers of different sizes, reduce impact force, and improve transportation efficiency. However, when there is a sudden stop, after the transport cabinet gradually decelerates, the coil assembly itself still has a forward inertial force, causing the coil assembly to slide relative to the transport cabinet, which can still lead to problems such as twisting and deformation of the coil assembly. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a transformer transport device. Under the action of the deceleration mechanism and the fixing mechanism, the coil group can not only be fixed, but also rotate along the center line of the rotating disk and the deceleration mechanism when the vehicle brakes suddenly. Under the action of the deceleration mechanism, the rotating coil group is decelerated, preventing the coil group from twisting and deforming under the inertial force generated in an instant, thus ensuring the safety of the coil group during transportation.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A transformer transport device includes a protective box and a cover plate. A fixing mechanism is provided inside the protective box, and a deceleration mechanism is provided on both the bottom plate and the cover plate of the protective box. A triangular chuck is provided on the deceleration mechanism, and the triangular chuck is located outside the center position of the deceleration mechanism. The fixing mechanism includes a partition, a rotating disk, and a fixing component mounted on the rotating disk. The rotating disk is rotatably mounted on the partition and is concentric with the deceleration mechanism. The fixing component is located outside the center of the rotating disk and is concentric with the triangular chuck on the deceleration mechanism on the bottom plate and cover of the protective box. The triangular chuck, in conjunction with the fixing component, fixes the coil assembly. When the vehicle brakes suddenly, the coil assembly will rotate along the center line of the rotating disk and the deceleration mechanism. Under the action of the deceleration mechanism, the rotating coil assembly can be decelerated. Clamping mechanisms are provided on both sides of the protective box. The cover plate is fixed to the top of the protective box by the clamping mechanisms. A support mechanism is provided on the top of the cover plate, and the support mechanism cooperates with the clamping mechanism.

[0008] Preferably, limit rods are provided on the two symmetrical inner walls of the protective box, and guide grooves are provided on the two symmetrical side walls of the partition. The guide grooves slide with the limit rods. A first positioning groove is also provided at the bottom of the cover plate. The first positioning groove cooperates with the top of the protective box. The limit rods can guide the partition and prevent the partition from tilting during installation and operation, thus ensuring the normal operation of the fixing mechanism.

[0009] Preferably, the fixing component includes a threaded rod, a connecting rod, a sliding rod, a support rod, a lifting block, a worm gear, a worm, and a motor. The middle part of the threaded rod is rotatably mounted on a rotating disk, and the threads on both sides of the center line of the threaded rod have opposite directions. The lifting blocks are symmetrically arranged on the upper and lower sides of the rotating disk and are threadedly connected to the threaded rod. A sliding hole is opened on the rotating disk, and several sliding holes are arranged in a circumferential array around the threaded rod. The sliding rod is slidably mounted in the sliding hole. The two ends of the connecting rod are rotatably mounted on the top side of the lifting block and the sliding rod, respectively. The support rod is symmetrically arranged on both sides of the sliding rod, and one end of the support rod is rotatably mounted on the end of the sliding hole on the rotating disk. A slotted hole is opened at both the upper and lower ends of the sliding rod. A fixing post is fixedly mounted on the other end of the support rod, and the fixing post is slidably mounted in the slotted hole. The worm gear is fixedly mounted in the middle of the threaded rod, and the worm is located on one side of the worm gear. The worm gear and worm mesh with each other, and the motor drives the worm to rotate. The fixing component can fix the coil assembly, ensuring that the coil assembly remains stable during transportation. To ensure the coil assembly functions properly, place it on the triangular chuck at the bottom of the protective box and secure it using the chuck. Then, place the fixing mechanism inside the protective box. Next, place another coil assembly on top of the fixing mechanism. Finally, fix the cover plate to the top of the protective box. The motor drives the worm gear to rotate, which in turn drives the worm wheel, which in turn drives the threaded rod. The threaded rod then moves the lifting block away from the partition. This movement of the lifting block moves one end of the connecting rod upward, while the other end of the connecting rod pushes the sliding rod outward. This outward movement of the connecting rod causes the fixing post on the support rod to move upward along the slot on the sliding rod. As the fixing post moves, one end of the support rod moves upward, and the other end of the support rod moves upward around the connection between the support rod and the partition. The angle between the bottom of the support rod and the partition increases, and the support rod also rotates away from the middle of the threaded rod, thus lifting the coil assembly and securing it to the cover plate or the bottom of the protective box.

[0010] Preferably, the fixing component further includes a support plate, with a through hole on the support rod. A sliding block, a guide rod, and a first spring are disposed in the through hole. The two ends of the guide rod are respectively fixedly installed on the two side walls of the through hole. The first spring is sleeved on the guide rod, and the sliding block is slidably installed on the guide rod. The support plate is disposed between the support rods on both sides of the sliding rod, and the support plate is rotatably connected to the sliding block. The support plate can achieve the purpose of supporting the coil assembly, preventing the sharp edges of the support plate from directly contacting the coil assembly and causing damage to the coil assembly, and ensuring that the coil assembly is always in a safe state during transportation.

[0011] Preferably, a placement groove is provided on the support plate to facilitate support of the coil assembly end. Stops are fixedly installed on both the upper and lower sides of the rotating disk on the sliding rod. The stops slide in cooperation with the rotating disk. The stops prevent the sliding rod from moving up and down during operation, ensuring the normal operation of the sliding rod. The placement groove facilitates the placement of the coil assembly, ensuring the safety and stability of the coil assembly during transportation.

[0012] Preferably, the clamping mechanism includes a vertical rod, an L-shaped rod, a support plate, a lower pressure plate, a lead screw, and a handle. The vertical rods are symmetrically arranged on the two outer walls of the protective box. Anti-foolproof grooves are opened on both sides of the cover plate, and the anti-foolproof grooves cooperate with the vertical rods. Fixing holes are opened on the vertical rods. The L-shaped rods are symmetrically arranged on both sides of the vertical rods. A fixing shaft is provided at the end of the L-shaped rods and is slidably arranged in the fixing holes. The support plate is fixedly installed on the other end of the L-shaped rods. A fixing groove is opened on the support plate. The lower pressure plate is slidably arranged in the fixing groove. The lead screw is threadedly installed on the support plate, and the bottom of the lead screw is rotatably installed on the lower pressure plate. The handle is fixedly installed on the top of the lead screw. The clamping mechanism can fix the cover plate to the top of the protective box, ensuring that the coil assembly is always under the protection of the protective box during transportation. Rotating the L-shaped rod makes the support plate position on top of the cover plate. Then, rotating the handle drives the lead screw to rotate. The rotation of the lead screw drives the lower pressure plate to move downward until the lower pressure plate is in close contact with the top of the cover plate, thereby achieving the purpose of fixing the cover plate to the top of the protective box.

[0013] Preferably, the support mechanism includes a fixed shell and a handle. The fixed shell is fixedly installed on the top of the cover plate. Inside the fixed shell, there is a rotating shaft, a reset component, a rotating arm, a push-pull rod, and a pad. The rotating shaft is rotatably installed on the top of the cover plate, and the top of the rotating shaft extends through the fixed shell to the top of the fixed shell. The handle is located above the fixed shell and is fixedly connected to the rotating shaft. The middle part of the rotating arm is fixedly installed on the rotating shaft. The pads are symmetrically arranged on both sides of the rotating arm. The two ends of the push-pull rod are rotatably connected to the ends of the rotating arm and the pads, respectively. A groove is formed on the pad, and the lower pressure plate cooperates with the groove. The reset component is installed on the rotating shaft. The support mechanism can cooperate with the clamping mechanism to fix the cover plate on the top of the protective box. The reset component can drive the pad to move to both sides, so that the pad is located below the lower pressure plate. The pad, together with the action of the lower pressure plate, fixes the cover plate on the top of the protective box.

[0014] Preferably, the reset component includes a fixed base, a gear, a rack, a guide rod, a movable block, and a second spring. The gear is fixedly mounted on the rotating shaft, the rack is disposed on one side of the gear and meshes with the gear, the movable block is fixedly mounted on one end of the rack, the fixed base is fixedly mounted on the inner wall of the fixed shell, the two ends of the guide rod are respectively fixedly mounted on the fixed base, the movable block is slidably mounted on the guide rod, and the second spring is sleeved on the guide rod. The reset component can drive the pad to reset, ensuring that the pad is always below the lower pressure plate, thereby ensuring the clamping quality of the clamping mechanism on the cover plate. The second spring can drive the rack to move. The rack and gear cooperate with each other. The movement of the rack will drive the gear to rotate, the rotation of the gear will drive the rotating arm to rotate, the rotation of the rotating arm will drive the push-pull rod to move, and the movement of the push-pull rod will continuously push the pad outward, ensuring that the pad is always below the lower pressure plate, thus also ensuring the clamping quality of the clamping mechanism on the cover plate.

[0015] Preferably, a second positioning groove is formed on the outer side of the pad, and a positioning block is also provided on the top of the cover plate. The second positioning groove cooperates with the positioning block. A first sliding groove is formed on the rack, and a first slide rail is provided on the inner wall of the fixed shell. The first slide rail is slidably engaged with the first sliding groove. A second slide rail is also provided on the cover plate, and a second sliding groove is also formed on the pad. The second slide rail is slidably engaged with the second sliding groove. The positioning block is used to position the pad and ensure the normal operation of the pad. The first sliding groove and the first slide rail not only guide the rack but also support it, preventing the rack from tilting during operation and ensuring the normal operation of the rack.

[0016] Preferably, the deceleration mechanism includes a mounting plate with a mounting cavity in the bottom plate or cover plate of the protective box. The mounting plate is rotatably mounted on the bottom plate or cover plate of the protective box, and its lower part is located within the mounting cavity. A mounting groove is formed in the middle of the mounting plate, and a fixed rod, a movable plate, a third spring, a pulling rod, and a pushing rod are arranged in the mounting groove. The two ends of the fixed rod are respectively fixedly mounted on the two side walls of the mounting groove. The pushing rod and the pulling rod are symmetrically arranged on both sides of the fixed rod. The movable plate is slidably mounted on the fixed rod. The third spring is sleeved on the fixed rod. The pushing rod is slidably mounted on the mounting plate. The two ends of the pulling rod are respectively rotatably mounted on one end of the movable rod and one end of the pushing rod. Several limiting blocks are provided on the inner wall of the mounting cavity. The limiting blocks are symmetrically arranged on both sides of the center line of the mounting plate. The limiting blocks cooperate with the push rod. The deceleration mechanism can decelerate the rotating coil group, preventing the coil group from always being in a high-speed rotation state, ensuring that the coil group can be quickly stabilized, and ensuring the safety of the coil group during transportation. When the end of the push rod cooperates with the limiting block, the push rod will move closer to the mounting groove. During the movement of the push rod, it will drive one end of the pull rod to move closer to the fixed rod. The other end of the pull rod will drive the moving plate to move downward. During the downward movement of the moving plate, the third spring will be stretched. During the stretching of the third spring, the friction between the push rod and the limiting block will be increased, thereby achieving the purpose of decelerating the rotating coil group.

[0017] Preferably, a limiting post is provided at the end of the fixing rod, and a clearance groove is provided at the edge of the mounting plate. The clearance groove cooperates with the limiting post. A through hole is opened on the side wall of the mounting groove on the mounting plate. The push rod slides with the through hole. The through hole ensures the normal operation of the push rod. The clearance groove can avoid the limiting post. At the same time, the clearance groove can also prevent the limiting post from interfering with the limiting block during the rotation of the mounting plate, thus ensuring the normal operation of the limiting post.

[0018] The beneficial effects of this invention are: 1) Under the action of the deceleration mechanism and the fixing mechanism, this device can not only fix the coil group, but also rotate along the center line of the rotating disk and the deceleration mechanism when the vehicle brakes suddenly. Under the action of the deceleration mechanism, the rotating coil group is decelerated to prevent the coil group from twisting and deforming under the inertial force generated in an instant, thus ensuring the safety of the coil group during transportation.

[0019] 2) The limit rod of this device can guide the partition and prevent the partition from tilting during installation and operation, thus ensuring the normal operation of the fixing mechanism.

[0020] 3) The fixing components of this device can secure the coil assembly, ensuring its stability during transportation and normal operation. The coil assembly is placed on the triangular chuck at the bottom of the protective box and secured there. The fixing mechanism is then placed inside the protective box, followed by another coil assembly placed on top of the fixing mechanism. Finally, the cover plate is fixed to the top of the protective box. The motor drives the worm gear, which in turn drives the worm wheel, which in turn drives the threaded rod. The threaded rod's rotation then moves the lifting block away from the isolation area. As the plate moves, the lifting block moves, causing one end of the connecting rod to move upward. The other end of the connecting rod then pushes the sliding rod outward. This outward movement of the connecting rod causes the fixed post on the support rod to move upward along the slot on the sliding rod. As the fixed post moves, it causes one end of the support rod to move upward, while the other end of the support rod moves upward around the connection between the support rod and the partition. The angle between the bottom of the support rod and the partition increases, and the support rod also rotates away from the middle of the threaded rod, thus lifting the coil assembly and fixing it to the bottom of the cover plate or protective box.

[0021] 4) The support plate of this device can support the coil assembly, prevent the sharp edges of the support plate from directly contacting the coil assembly and causing damage, and ensure that the coil assembly is always in a safe state during transportation.

[0022] 5) The stop block of this device can prevent the sliding rod from moving up and down during operation, ensuring the normal operation of the sliding rod. The placement slot facilitates the placement of the coil group, ensuring the safety and stability of the coil group during transportation.

[0023] 6) The clamping mechanism of this device can fix the cover plate to the top of the protective box, ensuring that the coil group is always under the protection of the protective box during transportation. Rotate the L-shaped rod to make the support plate position on the top of the cover plate, and then rotate the handle to drive the lead screw to rotate. The rotation of the lead screw drives the lower pressure plate to move downward until the lower pressure plate is in close contact with the top of the cover plate, thereby achieving the purpose of fixing the cover plate to the top of the protective box.

[0024] 7) The support mechanism of this device can cooperate with the clamping mechanism to fix the cover plate to the top of the protective box. The reset component can drive the pad plate to move to both sides, so that the pad plate is located below the lower pressure plate. The pad plate, together with the action of the lower pressure plate, fixes the cover plate to the top of the protective box.

[0025] 8) The reset component of this device can drive the pad to reset, ensuring that the pad is always below the lower pressure plate, thereby ensuring the clamping quality of the clamping mechanism on the cover plate. The second spring can drive the rack to move. The rack and gear cooperate with each other. The movement of the rack will drive the gear to rotate. The rotation of the gear will drive the rotating arm to rotate. The rotation of the rotating arm will drive the push-pull rod to move. The movement of the push-pull rod will continuously push the pad outward, ensuring that the pad is always below the lower pressure plate, thus ensuring the clamping quality of the clamping mechanism on the cover plate.

[0026] 9) The positioning block of this device is used to position the pad and ensure the normal operation of the pad. The first slide groove and the first slide rail not only guide the rack, but also support the rack to prevent it from tilting during operation and ensure the normal operation of the rack.

[0027] 10) The deceleration mechanism of this device can decelerate the rotating coil assembly, preventing it from always being in a high-speed rotation state, ensuring the rapid stabilization of the coil assembly, and ensuring the safety of the coil assembly during transportation. When the end of the push rod engages with the limit block, the push rod will move closer to the mounting groove. During the movement of the push rod, one end of the pull rod will move closer to the fixed rod, and the other end of the pull rod will move the moving plate downward. During the downward movement of the moving plate, the third spring will be stretched. During the stretching of the third spring, the friction between the push rod and the limit block will be increased, thereby achieving the purpose of decelerating the rotating coil assembly.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0047] like Figure 1 , Figure 2 , Figure 3 As shown, a transformer transport device includes a protective box 1 and a cover plate 3. A fixing mechanism 5 is provided inside the protective box 1. A deceleration mechanism 7 is provided on both the bottom plate of the protective box 1 and the cover plate 3. A triangular chuck 6 is provided on the deceleration mechanism 7, and the triangular chuck 6 is located outside the center position of the deceleration mechanism 7. The triangular chuck 6 is provided to facilitate the fixing of the ends of the coil group and ensure the safety of the coil group during transportation. Clamping mechanisms 2 are provided on both sides of the protective box 1. The cover plate 3 is fixed to the protective box 1 by the clamping mechanisms 2. A support mechanism 4 is provided on the top of the cover plate 3, and the support mechanism 4 cooperates with the clamping mechanism 2.

[0048] like Figure 1 As shown, an observation window 8 can also be set on the protective box 1 to facilitate staff to observe the clamping status of the coil group inside the protective box 1.

[0049] In this embodiment, as Figure 4 As shown, the fixing mechanism 5 includes a partition 502, a rotating disk 503, and a fixing member 505 mounted on the rotating disk 503. The rotating disk 503 is rotatably mounted on the partition 502. The rotating disk 503 is concentric with the deceleration mechanism 7. The fixing member 505 is located outside the center of the rotating disk 503, and the fixing member 505 is concentric with the triangular chuck 6 on the bottom plate of the protective box 1 and the deceleration mechanism 7 on the cover plate 3. The triangular chuck 6, in conjunction with the fixing member 505, fixes the coil group. When the vehicle brakes suddenly, the coil group will rotate along the center line of the rotating disk 503 and the deceleration mechanism 7. Under the action of the deceleration mechanism 7, the rotating coil group can be decelerated.

[0050] In this embodiment, as Figure 2 , Figure 4 As shown, limit rods 501 are provided on the two symmetrical inner walls of the protective box 1, and guide grooves 504 are provided on the two symmetrical side walls of the partition 502. The guide grooves 504 are slidably engaged with the limit rods 501. like Figure 11 As shown, a first positioning groove 302 is also provided at the bottom of the cover plate 3. The first positioning groove 302 cooperates with the top of the protective box 1. The setting of the limiting rod 501 can guide the partition 502, prevent the partition 502 from tilting during installation and operation, and ensure the normal operation of the fixing mechanism 5.

[0051] In this embodiment, as Figure 5 , Figure 6As shown, the fixing component 505 includes a threaded rod 509, a connecting rod 5010, a sliding rod 507, a support rod 5011, a lifting block 5012, a worm gear 5013, a worm 5015, and a motor 5016. The threaded rod 509 is rotatably mounted on a rotating disk 503 at its center. The threads on both sides of the center line of the threaded rod 509 have opposite directions of rotation. The lifting blocks 5012 are symmetrically arranged on the upper and lower sides of the rotating disk 503 and are threadedly connected to the threaded rod 509. A sliding hole 506 is opened on the rotating disk 503, and several sliding holes 506 are arranged in a circumferential array around the threaded rod 509. The sliding rod 507 is slidably mounted in the sliding hole 506. The connecting rod 5011... The two ends of 10 are respectively rotatably installed on the top side of the lifting block 5012 and the sliding rod 507. The support rod 5011 is symmetrically arranged on both sides of the sliding rod 507. One end of the support rod 5011 is rotatably installed on the end of the sliding hole 506 on the rotating disk 503. The upper and lower ends of the sliding rod 507 are both provided with strip holes 508. The other end of the support rod 5011 is fixedly installed with a fixing post 5023. The fixing post 5023 is slidably arranged in the strip hole 508. The worm gear 5013 is fixedly installed in the middle of the threaded rod 509. The worm 5015 is arranged on one side of the worm gear 5013. The worm gear 5013 and the worm 5015 mesh with each other. The motor 5016 is used to drive the worm 5015 to rotate.

[0052] The fixing component 505 secures the coil assembly, ensuring its stability during transport and guaranteeing its normal operation. The coil assembly is placed on the triangular chuck 6 at the bottom of the protective box 1 and secured using this chuck. The fixing mechanism 5 is then placed inside the protective box 1, followed by another coil assembly placed on top of the fixing mechanism 5. Finally, the cover plate 3 is fixed to the top of the protective box 1. The motor 5016 drives the worm gear 5015 to rotate, which in turn drives the worm wheel 5013. The worm wheel 5013 then drives the threaded rod 509, which in turn moves the lifting block 5012 away from the partition 502. This movement of the lifting block 5012... This will cause one end of the connecting rod 5010 to move upward, while the other end of the connecting rod 5010 will push the sliding rod 507 outward. The outward movement of the connecting rod 5010 will cause the fixing post 5023 on the support rod 5011 to move upward along the strip hole 508 on the sliding rod 507. During the movement of the fixing post 5023, one end of the support rod 5011 will move upward, and the other end of the support rod 5011 will move upward around the connection between the support rod 5011 and the partition 502. The angle between the other end of the support rod 5011 and the partition 502 will increase, and one end of the support rod 5011 will also rotate away from the middle of the threaded rod 509, thereby lifting the coil group and fixing the coil group to the bottom of the cover plate 3 or the protective box 1.

[0053] The 5016 motor can be controlled using wireless remote control technology, which is an existing technology and will not be discussed in detail here.

[0054] In this embodiment, as Figure 7 As shown, the fixing member 505 also includes a support plate 5021. A through hole 5017 is opened on the support rod 5011. A sliding block 5020, a guide rod 5018, and a first spring 5019 are arranged in the through hole 5017. The two ends of the guide rod 5018 are respectively fixedly installed on the two side walls of the through hole 5017. The first spring 5019 is sleeved on the guide rod 5018. The sliding block 5020 is slidably installed on the guide rod 5018. The support plate 5021 is arranged between the support rods 5011 on both sides of the sliding rod 507, and the support plate 5021 is rotatably connected to the sliding block 5020.

[0055] The support plate 5021 is designed to support the coil assembly, preventing the sharp edges of the support plate 203 from directly contacting the coil assembly and causing damage, thus ensuring that the coil assembly remains in a safe state during transportation.

[0056] In this embodiment, as Figure 7 As shown, a placement groove 5022 is provided on the support plate 5021 to facilitate the support of the coil assembly end. The placement groove 5022 facilitates the placement of the coil assembly and ensures the safety and stability of the coil assembly during transportation.

[0057] like Figure 6 As shown, stop blocks 5014 are fixedly installed on both the upper and lower sides of the rotating disk 503 on the sliding rod 507. The stop blocks 5014 slide in cooperation with the rotating disk 503. The setting of the stop blocks 5014 can prevent the sliding rod 507 from moving up and down during operation, thus ensuring the normal operation of the sliding rod 507.

[0058] In this embodiment, as Figure 10 As shown, the clamping mechanism 2 includes a vertical rod 201, an L-shaped rod 202, a support plate 203, a lower pressure plate 207, a lead screw 205, and a handle 204. The vertical rod 201 is symmetrically arranged on the two outer walls of the protective box 1, and a fixing hole 209 is opened on the vertical rod 201. The L-shaped rod 202 is symmetrically arranged on both sides of the vertical rod 201, and a fixing shaft 208 is provided at the end of the L-shaped rod 202. The fixing shaft 208 is slidably arranged in the fixing hole 209. The support plate 203 is fixedly installed on the other end of the L-shaped rod 202, and a fixing groove 206 is opened on the support plate 203. The lower pressure plate 207 is slidably arranged in the fixing groove 206. The lead screw 205 is threadedly installed on the support plate 203, and the bottom of the lead screw 205 is rotatably installed on the lower pressure plate 207. The handle 204 is fixedly installed on the top of the lead screw 205.

[0059] Among them, the upright pole 201 can also strengthen the protective box 1, prevent the protective box 1 from bending or being damaged during the transportation of the coil assembly, and ensure the safety of the coil assembly during transportation.

[0060] The clamping mechanism 2 can fix the cover plate 3 to the top of the protective box 1, ensuring that the coil group is always under the protection of the protective box 1 during transportation. Rotating the L-shaped rod 202 makes the support plate 203 located on top of the cover plate 3. Then, rotating the handle 204 drives the lead screw 205 to rotate. The rotation of the lead screw 205 drives the lower pressure plate 207 to move downward until the lower pressure plate 207 is in close contact with the top of the cover plate 3, thereby achieving the purpose of fixing the cover plate 3 to the top of the protective box 1.

[0061] In this embodiment, as Figure 11 As shown, anti-misfit grooves 301 are provided on both sides of the cover plate 3. The anti-misfit grooves 301 cooperate with the uprights 201. The anti-misfit grooves 301 improve the installation efficiency and installation quality of the cover plate 3.

[0062] In this embodiment, as Figure 12 , Figure 14 As shown, the support mechanism 4 includes a fixed shell 401 and a handle 402. The fixed shell 401 is fixedly installed on the top of the cover plate 3. Inside the fixed shell 401, there is a rotating shaft 405, a reset component 4010, a rotating arm 406, a push-pull rod 407, and a pad 408. The rotating shaft 405 is rotatably installed on the top of the cover plate 3, and the top of the rotating shaft 405 extends through the fixed shell 401 to the top of the fixed shell 401. The handle 402 is located above the fixed shell 401 and is fixedly connected to the rotating shaft 405. The middle part of the rotating arm 406 is fixedly installed on the rotating shaft 405. The pad 408 is symmetrically arranged on both sides of the rotating arm 406. The two ends of the push-pull rod 407 are rotatably connected to the ends of the rotating arm 406 and the pad 408, respectively. A groove 409 is opened on the pad 408, and the lower pressure plate 207 cooperates with the groove 409. The reset component 4010 is installed on the rotating shaft 405.

[0063] The support mechanism 4 can cooperate with the clamping mechanism 2 to fix the cover plate 3 on the top of the protective box 1. The reset member 4010 can drive the pad 408 to move to both sides, so that the pad 408 is located below the lower pressure plate 207. The pad 408, together with the action of the lower pressure plate 207, fixes the cover plate 3 on the top of the protective box 1.

[0064] In this embodiment, as Figure 15As shown, the reset component 4010 includes a fixed base 4015, a gear 4012, a rack 4013, a guide rod 4017, a moving block 4016, and a second spring 4018. The gear 4012 is fixedly mounted on the rotating shaft 405. The rack 4013 is disposed on one side of the gear 4012 and meshes with the gear 4012. The moving block 4016 is fixedly mounted on one end of the rack 4013. The fixed base 4015 is fixedly mounted on the inner wall of the fixed housing 401, one in front and one behind. The two ends of the guide rod 4017 are respectively fixedly mounted on the fixed base 4015. The moving block 4016 is slidably mounted on the guide rod 4017. The second spring 4018 is sleeved on the guide rod 4017.

[0065] The reset component 4010 can reset the pad 408, ensuring that the pad 408 is always below the lower pressure plate 207, thereby ensuring the clamping quality of the clamping mechanism 2 on the cover plate 3. The second spring 4018 can drive the rack 4013 to move. The rack 4013 cooperates with the gear 4012. The movement of the rack 4013 will drive the gear 4012 to rotate. The rotation of the gear 4012 will drive the rotating arm 406 to rotate. The rotation of the rotating arm 406 will drive the push-pull rod 407 to move. The movement of the push-pull rod 407 will continuously push the pad 408 outward, ensuring that the pad 408 is always below the lower pressure plate 207, which also ensures the clamping quality of the clamping mechanism 2 on the cover plate 3.

[0066] In this embodiment, as Figure 13 , Figure 16 As shown, a second positioning groove 4019 is provided on the outer side of the pad 408, and a positioning block 403 is also provided on the top of the cover plate 3. The second positioning groove 4019 cooperates with the positioning block 403. The positioning block 403 is used to position the pad 408 to ensure the normal operation of the pad 408.

[0067] like Figure 15 As shown, a first groove 4014 is formed on the rack 4013, and a first slide rail is provided on the inner wall of the fixed shell 401. The first slide rail and the first groove 4014 are slidably engaged. The first groove 4014 and the first slide rail not only guide the rack 4013, but also support the rack 4013, preventing the rack 4013 from tilting during operation and ensuring the normal operation of the rack 4013.

[0068] like Figure 13 , Figure 15As shown, a second slide rail 404 is also provided on the cover plate 3, and a second slide groove 4011 is also provided on the pad plate 408. The second slide rail 404 and the second slide groove 4011 slide in cooperation. The second slide rail 404 can guide the pad plate 408 and also support the pad plate 408, preventing the pad plate 408 from tilting during operation and ensuring the normal operation of the pad plate 408.

[0069] In this embodiment, as Figure 8 As shown, the deceleration mechanism 7 includes a mounting plate 701. A mounting cavity 101 is formed on the bottom plate or cover plate 3 of the protective housing 1. The mounting plate 701 is rotatably mounted on the bottom plate or cover plate 3 of the protective housing 1, with its lower part located within the mounting cavity 101. A mounting groove 703 is formed in the middle of the mounting plate 701. A fixed rod 707, a movable plate 705, a third spring 7010, a pulling rod 706, and a pushing rod 709 are arranged within the mounting groove 703. Both ends of the fixed rod 707 are respectively fixedly mounted in the mounting groove. On both sides of the 703, the push rod 709 and the pull rod 706 are symmetrically arranged on both sides of the fixed rod 707. The moving plate 705 is slidably mounted on the fixed rod 707. The third spring 7010 is sleeved on the fixed rod 707. The push rod 709 is slidably mounted on the mounting plate 701. The two ends of the pull rod 706 are respectively rotatably mounted on one end of the moving rod and one end of the push rod 709. Several limiting blocks 704 are provided on the inner wall of the mounting cavity 101. The limiting blocks 704 cooperate with the push rod 709.

[0070] The deceleration mechanism 7 can reduce the speed of the rotating coil group, preventing the coil group from always being in a high-speed rotation state, ensuring that the coil group can be quickly stabilized, and ensuring the safety of the coil group during transportation.

[0071] Since both the fixing component 505 and the triangular chuck 6 are eccentrically positioned, when the vehicle brakes suddenly, due to the inertia of the coil assembly, the coil assembly will rotate around the center of the rotating disk 503 and the mounting disk 701. When the mounting disk 701 rotates, it will drive the reduction mechanism 7 to rotate. During the rotation of the push rod 709 on the reduction mechanism 7, the end of the push rod 709 will cooperate with the limiting block 704. When one end of the push rod 709 moves along the outer wall of the limiting block 704, the other end of the push rod 709 will move towards the mounting groove 703 until the limiting post 708 moves into the clearance groove 702. During the movement of the other end of the push rod 709, one end of the pull rod 706 will move closer to the fixed rod 707. The other end of the pull rod 706 will move the moving plate 705 downward. During the downward movement of the moving plate 705, the third spring 7010 will be stretched. During the stretching process, the third spring 7010 will provide a reaction force to the moving plate 705. The reaction force is used to limit the movement of the moving plate 705, the pull rod 706 and the push-pull rod 407, thereby increasing the friction between the push rod 709 and the limit block 704, and achieving the purpose of decelerating the rotating coil group.

[0072] like Figure 3 , Figure 8 As shown, several limiting blocks 704 are symmetrically arranged on both sides of the center line of the mounting plate 701. Since there are no limiting blocks 704 installed on both sides of the center line (along the vehicle movement direction) near the mounting groove 703, when it is necessary to limit the mounting plate 701, the pushing rod 709 can cooperate with the limiting block 704 far away from the center line of the mounting groove 703, so that the triangular chuck 6 on the mounting plate 701 always has an angle with the vehicle movement direction, ensuring that the coil group can rotate around the mounting plate 701 during the vehicle's emergency braking or sudden acceleration.

[0073] In this embodiment, as Figure 8 As shown, a limiting post 708 is provided at the end of the fixing rod 707, and an avoidance groove 702 is provided at the edge of the mounting plate 701. The avoidance groove 702 cooperates with the limiting post 708. The setting of the avoidance groove 702 can avoid the limiting post 708. At the same time, the setting of the avoidance groove 702 can also prevent the limiting post 708 from interfering with the limiting block 704 during the rotation of the mounting plate 701, thus ensuring the normal operation of the limiting post 708.

[0074] like Figure 9 As shown, a through hole 7011 is formed on the side wall of the mounting groove 703 on the mounting plate 701. The push rod 709 slides with the through hole 7011, and the through hole 7011 ensures the normal operation of the push rod 709.

[0075] The installation process of the coil assembly: First, place the first coil group on the triangular chuck 6 at the bottom of the protective box 1, and then use the triangular chuck 6 at the bottom of the protective box 1 to initially fix the first coil group. Place the fixing mechanism 5 into the protective box 1, so that the fixing piece 505 below the partition 502 on the fixing mechanism 5 is inserted into the inside of the coil assembly; Place the second coil assembly on the fixing member 505 above the partition 502 of the fixing mechanism 5, and ensure that the fixing member 505 above the partition 502 can be inserted into the coil assembly. Place the cover plate 3 on top of the protective box 1, and fix the cover plate 3 on top of the protective box 1 under the action of the clamping mechanism 2 and the support mechanism 4, and ensure that the triangular chuck 6 on the cover plate 3 can clamp the top of the second coil group. Finally, the motor 5016 is turned on, driving the worm gear 5015 to rotate. The worm gear 5015 meshes with the worm wheel 5013. The rotation of the worm gear 5015 drives the worm wheel 5013 to rotate, which in turn drives the threaded rod 509 to rotate. The rotation of the threaded rod 509 causes the lifting block 5012 to move away from the partition plate 502. The movement of the lifting block 5012 causes one end of the connecting rod 5010 to move upward, and the other end of the connecting rod 5010 pushes the sliding rod 507 outward. The outward movement of the connecting rod 5010 causes the fixed column 5023 on the support rod 5011 to move along... As the sliding rod 507 moves upward through the slot 508, the fixed post 5023 moves, causing one end of the support rod 5011 to move upward. The other end of the support rod 5011 moves upward around the connection between the support rod 5011 and the partition 502, increasing the angle between the other end of the support rod 5011 and the partition 502. The other end of the support rod 5011 also rotates away from the center of the threaded rod 509, thus lifting the coil assembly away from the partition 502. Together with the cover plate 3 and the protective box 1, the two coil assemblies are fixed inside the protective box 1.

[0076] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
