Description

Technical Field

[0001] This application relates to the field of optical equipment technology, specifically to a flexible fixing device and its control method. Background Technology

[0002] With the continuous development of heavy optical equipment in practical engineering applications, higher requirements are being placed on the precision of its internal optical path. Due to the large weight and inconvenience of moving heavy optical equipment, it is often necessary to use a vehicle for transportation when it needs to be moved.

[0003] To prevent heavy optical equipment from shifting on the carrier during transport, it is typically secured to the carrier. Once transported to the designated location, it is detached to allow the heavy optical equipment to operate. Traditional securing devices usually use rigid mechanical connections to fix the optical equipment to the carrier, which can cause deformation of the optical equipment itself during transport. Simultaneously, the deformation and vibration of the carrier are transmitted to the optical equipment, further exacerbating the deformation. Although the materials used for the optical equipment have good rigidity, this is insufficient to offset the deformation that occurs during transport. Summary of the Invention

[0004] In view of the technical problems existing in the background art, this application provides a flexible fixing device and its control method. The flexible fixing device avoids the deformation of heavy optical equipment during transportation by the cooperation of locking components and vibration damping components. The cooperation of the first inclined surface and the second inclined surface makes the locking and unlocking process of the locking components and vibration damping components proceed smoothly. At the same time, it can also ensure that the distance between the upper surface of the locking tongue and the lower surface of the upper support plate is very small in the locked state, suppressing the impact of the vehicle vibration on the heavy optical equipment during transportation, further avoiding the deformation of the heavy optical equipment during transportation, and ensuring the accuracy of the optical path during the detection process of the heavy optical equipment.

[0005] In a first aspect, embodiments of this application provide a flexible fixing device disposed between a heavy optical device and a carrier, comprising a locking assembly and a vibration damping assembly disposed vertically; the locking assembly is detachably connected to the heavy optical device, and the vibration damping assembly is detachably connected to the carrier; the locking assembly includes a latch and a drive unit for rotating the latch; the upper surface of the latch has a first inclined surface; the vibration damping assembly includes an upper support plate, a flexible unit, and a lower support plate disposed sequentially from top to bottom; the upper support plate has a first opening through which the latch passes, and the length of the first opening, the length of the latch, and the width of the first opening decrease sequentially; the lower surface of the upper support plate has a second inclined surface matching the first inclined surface; the drive unit drives the latch to rotate, thereby realizing the locking and unlocking of the locking assembly and the vibration damping assembly.

[0006] In the technical solution of this application embodiment, by providing a first inclined surface on the upper surface of the latch and a second inclined surface on the lower surface of the upper support plate, compared to a planar latch and upper support plate, the gap between the first and second inclined surfaces continuously changes when the drive unit rotates the latch to lock or unlock. This inclined surface structure effectively prevents the latch and upper support plate from rubbing against each other or getting stuck, allowing the rotational locking and unlocking processes to proceed smoothly. This achieves the fixing and disengagement of the locking assembly and the vibration damping assembly, thereby achieving the fixing and disengagement of heavy optical equipment from the carrier. The vibration damping assembly effectively prevents the impact of vibration or even deformation of the carrier during transportation on the heavy optical equipment, playing a buffering role. Furthermore, when the locking assembly and the vibration damping assembly are locked together, the distance between the upper surface of the locking tongue and the lower surface of the upper support plate is very small, ensuring that the locking assembly and the vibration damping assembly are firmly fixed into a single structure. Even if the carrier vibrates or even deforms during the transportation of heavy optical equipment, the locking assembly does not undergo relative displacement with respect to the vibration damping assembly. This means that the space for movement of the heavy optical equipment relative to the carrier is very small, further suppressing the impact of carrier vibration on the heavy optical equipment during transportation, preventing deformation of the heavy optical equipment during transportation, and ensuring the accuracy of the optical path during the testing process of the heavy optical equipment. In other words, this application, through the mutual cooperation of the vibration damping assembly, the first inclined surface, and the second inclined surface, prevents the optical equipment from deforming during transportation and ensures the accuracy of the internal optical path of the heavy optical equipment itself.

[0007] In some embodiments, the first inclined surface has a centrally symmetrical structure, and the first inclined surface is set at different heights along the rotation direction of the locking tongue; after the locking tongue is rotated and locked, the second inclined surface corresponds to the first inclined surface vertically, and the high position of the first inclined surface corresponds to the low position of the second inclined surface.

[0008] In this embodiment, by controlling the high position of the first inclined surface and the low position of the second inclined surface to correspond when the latch is locked, during the rotational locking process, the low position of the first inclined surface first passes below the low position of the second inclined surface, and then moves to below the high position of the second inclined surface. This means the gap between the upper surface of the latch and the lower surface of the upper support plate gradually decreases. This operation ensures a smooth locking process and also minimizes the distance between the upper surface of the latch and the lower surface of the upper support plate when the latch is locked, effectively suppressing the impact of vehicle vibration on heavy optical equipment during transportation. Conversely, during the rotational unlocking process, the gap between the upper surface of the latch and the lower surface of the upper support plate gradually increases, effectively preventing friction or jamming between the latch and the upper support plate, thus ensuring a smooth rotational unlocking process.

[0009] In some embodiments, when the latch is rotated and locked, the distance between the lower surface of the upper support plate and the upper surface of the latch is 0.5mm ± 0.2mm.

[0010] In some embodiments, the flexible unit is a spiral steel wire rope; both the lower surface of the upper support plate and the upper surface of the lower support plate are provided with fixing blocks, and the spiral steel wire rope is connected to the upper support plate and the lower support plate respectively through the fixing blocks.

[0011] In this embodiment, by setting the flexible unit as a spiral steel wire rope, when the vehicle vibrates or even deforms during transportation, the steel wire rope can, to a certain extent, isolate the impact of the vehicle's vibration or deformation on the heavy optical equipment, playing a buffering and vibration reduction role. At the same time, the steel wire rope has high rigidity and small deformation under load, ensuring the stable transportation of heavy optical equipment.

[0012] In some embodiments, the locking assembly further includes an L-shaped support frame, one side of which is connected to the heavy-duty optical device and the other side is in contact with the upper support plate; the drive unit is disposed on the support frame, and the support frame has a second opening located directly above the first opening, the locking tongue passing through the second opening and the first opening.

[0013] In some embodiments, the vibration damping assembly further includes a guide pin disposed on the upper surface of the upper support plate; the support frame is provided with a third opening, and the guide pin is sleeved in the third opening.

[0014] In this embodiment, the locking assembly and the vibration damping assembly are fixed horizontally by the cooperation of the guide pin and the third opening, while the locking tongue and the upper support plate fix the locking assembly and the vibration damping assembly vertically. This arrangement makes the fixation between the locking assembly and the vibration damping assembly more secure. That is, the cooperation between the L-shaped support frame of the locking assembly and the guide pin of the vibration damping assembly, as well as the cooperation between the locking tongue and the upper support plate, makes the fixation between the locking assembly and the vibration damping assembly more secure.

[0015] In some embodiments, the locking assembly further includes an automatic control unit electrically connected to the drive unit; the automatic control unit includes a control box and an operating switch and a display screen disposed on the outer surface of the control box; the operating switch includes a locking switch and an unlocking switch; the display screen is used to display overcurrent, overvoltage, undervoltage and the open / locked status information of the operating switch.

[0016] In this embodiment, by setting up an automatic control unit, the locking and disengaging of the locking and vibration damping components can be achieved simply by operating the locking and unlocking switches, thereby enabling the fixation and disengagement of heavy optical equipment and carriers, making operation simple. Simultaneously, the display screen can also show overcurrent, overvoltage, undervoltage, and the status information of the operating switches (open / locked), facilitating real-time monitoring of the control box by staff and ensuring high safety.

[0017] In some embodiments, the drive unit includes a driver, a motor, and a power unit connected in sequence; the driver is energized and connected to the operating switch; and the power unit is connected to the locking tongue.

[0018] In this embodiment, the driver receives the command issued by the operation switch and drives the motor to work, thereby driving the power unit to work, which in turn drives the bolt to rotate, realizing the locking and unlocking of the bolt.

[0019] In some embodiments, the power unit includes a worm gear, a worm wheel, a rotating shaft, and a position switch. The worm gear is connected to the output shaft of the motor, and the worm gear and the worm wheel are meshed together. One end of the rotating shaft is connected to the worm wheel, and the other end is connected to the locking tongue. The position switch is energized and connected to the driver.

[0020] Secondly, this application provides a control method for a flexible fixing device. When the heavy optical equipment needs to be moved, the heavy optical equipment is lowered by a lifting device so that the locking tongue passes through the first opening. Then, the driving unit drives the locking tongue to rotate and lock, thereby fixing the heavy optical equipment and the carrier. After the heavy optical equipment is moved to a designated position, the driving unit drives the locking tongue to rotate and unlock, thereby separating the heavy optical equipment from the carrier. Then, the lifting device raises the heavy optical equipment to the position to be measured, thereby measuring the heavy optical equipment.

[0021] In the technical solution of this application embodiment, the locking component and the vibration damping component cooperate to achieve flexible fixation of heavy optical equipment and carrier, thereby avoiding the impact of carrier deformation on heavy optical equipment during transportation.

[0022] The above description is only an overview of the technical solution of this application.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0040] Traditional fastening devices for heavy optical equipment and their carriers typically use rigid mechanical connections. This leads to deformation of the heavy optical equipment during transport, and the deformation and vibration of the carrier are transmitted to the heavy optical equipment, further exacerbating the deformation. Therefore, achieving a flexible connection between heavy optical equipment and its carrier is of paramount importance.

[0041] To address the technical problem of deformation of heavy optical equipment caused by rigid connections between heavy optical equipment and carriers, this application provides a flexible fixing device and its control method. The flexible fixing device, through the cooperation of locking and vibration damping components, prevents deformation of the heavy optical equipment during transportation. The cooperation of the first and second inclined surfaces ensures smooth locking and unlocking of the locking and vibration damping components, while also maintaining a small gap between the upper surface of the locking tongue and the lower surface of the upper support plate in the locked state. This suppresses the impact of carrier vibration on the heavy optical equipment during transportation, further preventing deformation and ensuring the accuracy of the optical path during the detection process.

[0042] For ease of explanation, the following embodiments will be described using a flexible fixing device 1000 according to an embodiment of this application as an example.

[0043] Please refer to Figure 1 , Figure 1 This is a schematic diagram showing the overall state after the heavy optical equipment 1 and the carrier 2 are connected by a flexible fixing device 1000 according to some embodiments of this application. The flexible fixing device 1000 is disposed between the heavy optical equipment 1 and the carrier 2. Please refer to... Figure 2 and Figure 3The flexible fixing device 1000 includes a locking assembly 3 and a vibration damping assembly 4 arranged vertically. The locking assembly 3 is detachably connected to the heavy optical equipment 1, and the vibration damping assembly 4 is detachably connected to the carrier 2. The locking assembly 3 includes a locking tongue 31 and a drive unit 32 for rotating the locking tongue 31. The upper surface of the locking tongue 31 is provided with a first inclined surface 33. The vibration damping assembly 4 includes an upper support plate 41, a flexible unit 42, and a lower support plate 43 arranged sequentially from top to bottom. The upper support plate 41 is provided with a first opening 44 through which the locking tongue 31 passes. The length of the first opening 44, the length of the locking tongue 31, and the width of the first opening 44 decrease sequentially. The lower surface of the upper support plate 41 is provided with a second inclined surface 45 that matches the first inclined surface 33. The drive unit 32 drives the locking tongue 31 to rotate, so as to realize the locking and unlocking of the locking assembly 3 and the vibration damping assembly 4. Specifically, by providing a first inclined surface 33 on the upper surface of the locking tongue 31 and a second inclined surface 45 on the lower surface of the upper support plate 41, compared to a planar locking tongue and upper support plate, when the driving unit 32 drives the locking tongue 31 to rotate for locking or unlocking, the gap between the first inclined surface 33 and the second inclined surface 45 continuously changes. The inclined surface structure can effectively prevent the locking tongue 31 and the upper support plate 41 from rubbing against each other or getting stuck, allowing the rotation locking and unlocking process to proceed smoothly. This achieves the fixing and disengagement of the locking assembly 3 and the vibration damping assembly 4, thereby achieving the fixing and disengagement of the heavy optical equipment 1 and the carrier 2. When the carrier 2 vibrates or even deforms during the transportation of the heavy optical equipment 1, the vibration damping assembly 4 absorbs the deformation energy, effectively preventing the impact of vibration or deformation on the heavy optical equipment 1. That is, the vibration damping assembly 4 can isolate the impact of the vibration or deformation of the carrier 2 on the heavy optical equipment 1, playing a buffering role. Furthermore, when the locking component 3 and the vibration damping component 4 are locked together, the distance between the upper surface of the locking tongue 31 and the lower surface of the upper support plate 41 is very small. This makes the locking component 3 and the vibration damping component 4 firmly fixed into an integrated structure. Even if the carrier 2 vibrates or even deforms during the transportation of the heavy optical equipment 1, the locking component 3 will not have any relative displacement with respect to the vibration damping component 4. That is, the space for the heavy optical equipment 1 to move relative to the carrier 2 is very small, which further suppresses the impact of the carrier 2 vibration on the heavy optical equipment 1 during transportation, avoids the deformation of the heavy optical equipment 1 during transportation, and ensures the accuracy of the optical path during the detection process of the heavy optical equipment 1. (If the distance between the upper surface of the locking tongue 31 and the lower surface of the upper support plate 41 is large, the fixation between the locking component 3 and the vibration damping component 4 will not be tight. The locking component 3 can have a large relative displacement with respect to the vibration damping component 4. That is, the space for the heavy optical equipment 1 to move relative to the carrier 2 is large. When the carrier 2 vibrates or even deforms during the transportation of the heavy optical equipment 1, the heavy optical equipment 1 will shake violently relative to the carrier 2, which will affect the accuracy of its optical path.)In other words, through the synergy of the vibration damping components, the first inclined surface, and the second inclined surface, this application achieves highly reliable and convenient locking while avoiding the deformation of the heavy optical equipment 1 caused by the mechanical hard connection method of the traditional locking structure. At the same time, it reduces the impact of the vibration and deformation of the carrier 2 on the heavy optical equipment 1, and meets the requirement of maintaining the optical path accuracy of the heavy optical equipment 1 during transportation. That is, the present invention largely avoids the impact of hard contact, long distance, and large vibration transportation process on the internal optical path accuracy of the heavy optical equipment 1, and ensures the accuracy of the detection of the heavy optical equipment 1.

[0044] Please see Figure 5 The structure of the locking tongue 31 shown and Figure 6 The structure of the upper support plate 41 shown has the same shape for the upper and lower surfaces of the latch 31 as the first opening 44, and ensures that the length of the first opening 44 is greater than the length of the latch 31, and the width of the first opening 44 is greater than the width of the latch 31 but less than the length of the latch 31. With this configuration, when the length direction of the latch 31 is parallel to the length direction of the first opening 44, the latch 31 passes smoothly through the first opening 44. Then, the drive unit 32 drives the latch 31 to rotate, so that the length direction of the latch 31 is perpendicular to the length direction of the first opening 44, and the latch is locked by rotation.

[0045] Furthermore, in this embodiment, the first inclined surface 33 has a centrally symmetrical structure, and the first inclined surface 33 is set at varying heights along the rotation direction of the latch 31, such as... Figure 5 As shown, the first inclined plane 33 is set from high to low along the arrow directions of X1 and X2. Figure 6 As shown, the second inclined plane 45 is set from high to low along the arrow directions of Y1 and Y2. Figure 7As shown, when the latch 31 is rotated clockwise to lock, the second inclined surface 45 corresponds vertically to the first inclined surface 33, and the higher position of the first inclined surface 33 corresponds to the lower position of the second inclined surface 45. At this time, the vertically corresponding first inclined surface 33 and second inclined surface 45 are parallel to each other (the inclined surface where arrow X1 is located corresponds vertically to the inclined surface where arrow Y1 is located, and the inclined surface where arrow X2 is located corresponds vertically to the inclined surface where arrow Y2 is located). When the latch 31 is rotated to lock, the distance between the lower surface of the upper support plate 41 and the upper surface of the latch 31 is 0.5mm ± 0.2mm. During the clockwise rotation locking process, the lower position of the first inclined surface 33 first passes below the lower position of the second inclined surface 45, and then moves to below the higher position of the second inclined surface 45. This means the gap between the upper surface of the latch 31 and the lower surface of the upper support plate 41 gradually decreases. This design ensures a smooth locking process (if foreign objects prevent locking between the first and second inclined surfaces 33 and 45 during the rotation locking process, the latch can be unlocked first, allowing the foreign objects to fall off the first inclined surface 33, and then the rotation locking operation can be performed again). Simultaneously, it ensures that the distance between the upper surface of the latch 31 and the lower surface of the upper support plate 41 is very small when the latch is locked, effectively suppressing the impact of vibrations from the carrier 2 on the heavy optical equipment 1 during transportation. Conversely, during the clockwise rotation unlocking process, the gap between the upper surface of the latch 31 and the lower surface of the upper support plate 41 gradually increases, effectively preventing friction or jamming between the latch 31 and the upper support plate 41, ensuring a smooth clockwise unlocking process. For the latch with a planar upper surface and the upper support plate with a planar lower surface, in order to keep the distance between the upper surface of the latch and the lower surface of the upper support plate very small during rotation, the gap between the upper surface of the latch and the lower surface of the upper support plate must always be maintained at a very small distance throughout the rotation process. Even minor imperfections on the upper surface of the latch and the lower surface of the upper support plate (such as unevenness, coating peeling, etc.) will affect the smooth progress of the locking and unlocking process. At this time, in order to achieve the smooth progress of the rotation locking and unlocking process, the distance between the upper surface of the latch and the lower surface of the upper support plate must be increased. However, a larger distance will amplify the impact brought by the carrier 2 at the heavy optical device 1, thereby causing the internal optical path to deviate.

[0046] Furthermore, in the embodiments of this application, such as Figure 4As shown, the flexible unit 42 is a spiral steel wire rope. Fixing blocks 46 are provided on the lower surface of the upper support plate 41 and the upper surface of the lower support plate 43. Each fixing block 46 has several fifth openings. The spiral steel wire rope passes through these fifth openings and connects to the upper support plate 41 and the lower support plate 43, respectively. By configuring the flexible unit 42 as a spiral steel wire rope, when the carrier 2 vibrates or even deforms during transportation, the steel wire rope can, to a certain extent, isolate the impact of the vibration or deformation of the carrier 2 on the heavy optical equipment 1, thus providing buffering and vibration reduction. Simultaneously, the steel wire rope has high rigidity and minimal deformation under load, ensuring stable transportation of the heavy optical equipment 1.

[0047] Furthermore, in the embodiments of this application, such as Figure 2 and Figure 3 As shown, the locking assembly 3 also includes an L-shaped support frame 34. One side of the support frame 34 is detachably connected to the heavy optical equipment 1 by screws, and the other side is in contact with the upper support plate 41. The drive unit 32 is disposed on the support frame 34. The support frame 34 is provided with a second opening located directly above the first opening 44. The locking tongue 31 passes through the second opening and the first opening 44.

[0048] Furthermore, in the embodiments of this application, such as Figure 2 and Figure 3 As shown, the vibration damping component 4 also includes a guide pin 47 disposed on the upper surface of the upper support plate 41; the support frame 34 has a third opening, and the guide pin 47 is fitted into the third opening. Through the cooperation of the guide pin 47 and the third opening, the locking component 3 and the vibration damping component 4 are fixed in the horizontal direction. Simultaneously, the cooperation of the locking tongue 31 and the upper support plate 41 can fix the locking component 3 and the vibration damping component 4 in the vertical direction. That is, the guide pin 47 bears the lateral load on the horizontal plane, while the locking tongue 31, the upper support plate 41, and the drive unit 32 bear the load in the normal direction of the horizontal plane. Through the cooperation between the locking tongue and the upper support plate, and the cooperation between the support frame 34 and the guide pin 47, the locking component and the vibration damping component are firmly fixed into an integral structure. This arrangement makes the fixation between the locking component 3 and the vibration damping component 4 more secure. The material of the guide pin 47 is 05Cr. 17 The Ni4Cu4Nb stainless steel has a diameter of 39.5mm at the contact point with the third opening, and a fit length (i.e., the gap between the third opening and the guide pin 47 after installation) of 5mm. A single guide pin 47 can bear a radial load of approximately 2.3 tons.

[0049] Furthermore, in the embodiments of this application, such as Figure 2As shown, the locking assembly 3 also includes an automatic control unit electrically connected to the drive unit 32. The automatic control unit includes a control box 35 and an operating switch and display screen (not shown in the figure) disposed on the outer surface of the control box 35. The drive unit 32 is disposed in the control box 35. The operating switch includes a locking switch and an unlocking switch. The display screen is used to display overcurrent, overvoltage, undervoltage, and the status information of the operating switch being open or locked. By setting up an automatic control unit, the locking assembly 3 and the vibration damping assembly 4 can be locked and disengaged simply by operating the locking and unlocking switches, thereby achieving the fixation and disengagement of the heavy optical equipment 1 and the carrier 2, which is simple to operate. At the same time, the display screen can also display overcurrent, overvoltage, undervoltage, and the status information of the operating switch being open or locked, which is convenient for staff to monitor the status inside the control box 35 in real time, ensuring high safety. A knob (not shown in the figure) is also provided on the outer surface of the control box 35, which can be used to open the control box 35 for regular maintenance of its interior.

[0050] Further, in this embodiment, the drive unit 32 includes a driver 321, a motor 322, and a power unit connected in sequence. One end of the driver 321 is energized and connected to the operation switch, and the other end is energized and connected to the motor 322. The driver 321 is also connected to a display screen via a signal line to control and display the working status. The power unit is connected to the latch 31. In this embodiment, the driver 321 receives commands from the operation switch and drives the motor 322 to work, thereby driving the power unit to work, which in turn drives the latch 31 to rotate, thus locking and unlocking the latch 31. See [link to locking and unlocking process] for details. Figure 9 As shown, when locking is required, pressing the locking switch sends a "locking command" to the driver 321, which in turn activates the motor 322, thereby driving the power unit to rotate the bolt 31 90° clockwise. Locking is complete when the length of the bolt 31 is perpendicular to the length of the first opening 44. When unlocking is required, pressing the unlocking switch sends a "unlocking command" to the driver 321, which in turn activates the motor 322, driving the power unit to rotate the bolt 31 90° counterclockwise. Unlocking is complete when the length of the bolt 31 is parallel to the length of the first opening 44. The operation is simple and convenient, allowing for one-button locking and unlocking.

[0051] Furthermore, in the embodiments of this application, such as Figure 8 As shown, the power unit includes a worm gear 323, a worm wheel 324, a rotating shaft 325, and a position switch 326. The worm gear 323 is connected to the output shaft of the motor 322. The worm gear 323 and the worm wheel 324 have a meshing structure. The self-locking lead angle of the worm wheel 324 and the worm gear 323 transmission is 3°16′. One end of the rotating shaft 325 is connected to the worm wheel 324, and the other end is connected to the locking tongue 31 (e.g., ...). Figure 5As shown, the latch 31 has a fourth opening 36 for the rotating shaft 325 to pass through. The position switch 326 is energized and connected to the driver 321. After receiving a command, the driver 321 drives the motor 322 to work. The motor 322 drives the worm gear 323 to rotate, which in turn drives the worm wheel 324 to rotate, thereby driving the rotating shaft 325 to rotate, thus realizing the rotation of the latch 31. When the latch 31 reaches the locked or unlocked state, the position switch 326 transmits the signal to the driver 321, thereby stopping its operation and realizing the limit feedback function of the driver 321. The diameter of the rotating shaft 325 is 40mm, and the material is 17Cr. 14 Ni2 stainless steel, a single pivot 325 can bear an axial load of approximately 6 tons; the locking tongue 31, upper support plate 41, and pivot 325 bear the load in the horizontal normal direction. That is, the guide pin 47 and pivot 325 achieve the large load-bearing function in all directions.

[0052] Figure 7 When the locking tongue 31 is rotated and locked, the locking tongue 31 is not located in the center of the upper support plate 41. In practical applications, the position of the locking tongue 31 can be adjusted according to the position of the rotating shaft 325, and the position of the second inclined surface 45 can be adjusted accordingly.

[0053] The number and specific placement of the flexible fixing devices 1000 are determined based on the shape and weight of the heavy optical equipment 1. For example... Figure 1 In the embodiment shown, the heavy optical equipment 1 weighs 14 tons, and there are three flexible fixing devices 1000, that is, two flexible fixing devices 1000 are symmetrically arranged on both sides of the heavy optical equipment 1. Figure 1 In the side view, another flexible fixing device 1000 is located... Figure 1 On the other side of point A, where the two flexible fixing devices 1000 overlap, one flexible fixing device 1000 is located at the bottom of the heavy-duty optical device 1 (the bottom of the heavy-duty optical device 1 has a groove, the sidewall of which is connected to the support frame 34). In addition, four vibration damping components 4 are also provided. Figure 1 Only two vibration damping components 4 are shown in the figure, and the other two overlap with the two shown in the figure. The upper surface of the support plate 41 of the vibration damping component 4 is not provided with guide pins 47. The vibration damping component 4 is connected to the carrier 2, but not to the heavy optical equipment 1, and only serves as a support.

[0054] Secondly, this application also provides a control method for the aforementioned flexible fixing device. When it is necessary to move the heavy optical equipment 1, the heavy optical equipment 1 is lowered by the lifting device, so that the locking tongue 31 passes through the first opening 44. Then, the drive unit 32 drives the locking tongue 31 to rotate and lock, thereby fixing the heavy optical equipment 1 and the carrier 2. After the heavy optical equipment 1 is moved to the designated position, the drive unit 32 drives the locking tongue 31 to rotate and unlock, thereby separating the heavy optical equipment 1 from the carrier 2. Then, the lifting device raises the heavy optical equipment 1 to the position to be tested, enabling the use of the heavy optical equipment 1. In practical applications, the locking component 3 remains connected to the heavy optical equipment 1 without disassembly, and the vibration damping component 4 remains connected to the carrier 2 without disassembly. The fixing and detachment of the heavy optical equipment 1 and the carrier 2 can be achieved simply by locking and unlocking the locking component 3 and the vibration damping component 4.

[0055] In the technical solution of this application embodiment, the locking component 3 and the vibration damping component 4 cooperate to achieve flexible fixation of the heavy optical equipment 1 and the carrier 2, thereby avoiding the impact of the deformation of the carrier 2 on the heavy optical equipment during transportation.

[0056] Please also refer to Figures 1 to 8 According to one or more embodiments of this application, the locking component 3 and the vibration damping component 4 cooperate to prevent the heavy optical equipment 1 from deforming during transportation; the cooperation of the first inclined surface 33 and the second inclined surface 45 makes the locking and unlocking process of the locking component 3 and the vibration damping component 4 proceed smoothly, while also ensuring that the distance between the upper surface of the locking tongue 31 and the lower surface of the upper support plate 41 is very small in the locked state, suppressing the impact of the vibration of the carrier 2 on the heavy optical equipment 1 during transportation, further preventing the heavy optical equipment 1 from deforming during transportation, and ensuring the accuracy of the optical path during the detection process of the heavy optical equipment 1.

The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
