Description

Technical Field

[0001] This application relates to the field of intelligent assembly and manufacturing technology for power equipment, specifically to a device that can adjust the posture of large components online. Background Technology

[0002] In the manufacturing or assembly of equipment such as power equipment, energy equipment, petrochemical equipment, and aerospace equipment, the hoisting of large components is often involved. For example, in automated intelligent assembly and manufacturing production lines for power equipment, hoisting equipment is commonly used to move heavy components or products. To facilitate the adjustment of the attitude of the hoisted object, the lifting devices in existing hoisting equipment are generally equipped with a leveling mechanism. The existing leveling mechanism typically uses four sets of telescopic actuators (such as cylinders or lead screw motors) connected to the hoisted object. A level instrument is installed on the hoisted object to provide real-time feedback on the levelness. The levelness of the hoisted object can be adjusted by controlling one or more sets of telescopic actuators.

[0003] However, in some applications, such as the production of disconnector boxes or high-voltage switches, it is necessary to assemble some heavy components. This assembly process requires more than just simple alignment and insertion; it also requires driving the rotation of shafts or gear rings to achieve gear spline engagement. Therefore, a dedicated quick-change disc fixture is needed on the lifting equipment to perform this operation. Thus, in these applications, the lifting equipment does not merely lift and move a component; rather, a quick-change disc fixture is used to lift and transport an object to a predetermined position for docking with another target component. Existing lifting equipment is only used for leveling the object being lifted and cannot meet the requirements of this process. Currently, the only solution is to manually adjust the quick-change disc fixture on-site, visually inspecting and adjusting it. This process is not only time-consuming but also poses risks of impact and safety hazards.

[0004] In addition, large components are often heavy, and their large size and weight further increase the difficulty of attitude adjustment. Summary of the Invention

[0005] This application aims to address one of the technical problems in related technologies to a certain extent. To this end, this application provides a device for online adjustment of the attitude of large components.

[0013] The application of this application has the following beneficial effects: By setting up an adjustment component and a first detection module, the first detection module monitors the tilt angle of the quick-change tray tooling relative to the horizontal plane in real time. Based on the detection information from the first detection module, the adjustment component is controlled to adjust its operation. The adjustment component adjusts the relative position between the first connecting structure and the second connecting structure, thereby adjusting the angle of the quick-change tray tooling relative to the object being lifted. Thus, the quick-change tray tooling can be adjusted to be horizontal with the mating surface of the object being lifted, facilitating the docking operation. Simultaneously, during the docking and assembly process between the object being lifted and the target component, both the quick-change tray tooling and the object being lifted can be adjusted to be horizontal with the mating surface of the target component, facilitating the docking operation. Furthermore, during the lifting process, the lifting posture can be adjusted in real time according to the actual needs of the object being lifted, ensuring a smooth and safe transfer process.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] Example 1: This example provides a device for online attitude adjustment of large components, such as... Figures 1 to 7 As shown, the device includes a first connecting structure 1, a second connecting structure, an adjustment component, a first detection module 200, and a controller 4. The first connecting structure 1 is used to connect to the hoisting equipment, the second connecting structure is used to connect to the quick-change tray fixture 6, and the adjustment component is disposed between the first connecting structure 1 and the second connecting structure. The first detection module 200 is disposed on the adjustment component and is used to detect the tilt angle of the quick-change tray fixture 6 relative to the horizontal plane. The controller 4 is connected to the first detection module 200 and the adjustment component. In this embodiment, the adjustment component is configured to adjust the relative position between the first connecting structure 1 and the second connecting structure according to the detection information from the first detection module 200 under the control of the controller 4, thereby adjusting the angle of the quick-change tray fixture 6 relative to the hoisted object.

[0040] By setting up an adjustment component and a first detection module 200, the first detection module 200 monitors the tilt angle of the quick-change tray fixture 6 relative to the horizontal plane in real time. Based on the detection information from the first detection module 200, the adjustment component is controlled to adjust the relative position between the first connecting structure 1 and the second connecting structure, thereby adjusting the angle of the quick-change tray fixture 6 relative to the object being lifted. Thus, the quick-change tray fixture 6 can be adjusted to be horizontal with the mating surface of the object being lifted, facilitating the docking operation. Simultaneously, during the docking and assembly process between the object being lifted and the target component 9, both the quick-change tray fixture 6 and the object being lifted can be adjusted to be horizontal with the mating surfaces of the target component 9, facilitating the docking operation. Furthermore, during the lifting process, the lifting posture can be adjusted in real time according to the actual needs of the object being lifted, ensuring a smooth and safe transfer process.

[0041] Meanwhile, the device provided in this embodiment can also select a suitable quick-change plate tool 6 according to the actual situation of the object being lifted. It is only necessary to disassemble and assemble the quick-change plate tool 6 relative to the second connecting structure, thereby improving the applicability of the device.

[0042] Combination Figure 1 and Figure 6 As shown, the adjustment assembly in this embodiment includes a first adjustment mechanism 2 and a second adjustment mechanism 3. The first adjustment mechanism 2 is connected to the first connecting structure 1 and is used to drive the first connecting structure 1 to reciprocate along the first direction P. The second adjustment mechanism 3 is connected to the first adjustment mechanism 2 and is used to drive the first adjustment mechanism 2 to reciprocate along the second direction S. The second connecting structure is fixed to the second adjustment mechanism 3. The first direction P and the second direction S are perpendicular to each other. By designing the first adjustment mechanism 2 and the second adjustment mechanism 3 as a cross-shaped motion structure, the complex spatial angle adjustment is simplified to translational drive, simplifying the overall structure of the adjustment assembly. At the same time, under the action of gravity, the spatial angle adjustment of the quick-change tray tooling 6 can be achieved by the translational movement of the internal components of the adjustment assembly along the first direction P and the second direction S.

[0043] Specifically, in combination Figure 4 As shown, in this embodiment, the first adjustment mechanism 2 includes a first support frame 20, a first slide rail 21, and a first drive mechanism 22, and the second adjustment mechanism 3 includes a second support frame 30, a second slide rail 31, and a second drive mechanism 32. The first slide rail 21 and the first drive mechanism 22 are both disposed on the first support frame 20. The first slide rail 21 extends along a first direction P, and the first connecting structure 1 is slidably disposed on the first support frame 20 via the first slide rail 21. The first drive mechanism 22 is connected to the first connecting structure 1 and is used to drive the first connecting structure 1 to reciprocate along the first slide rail 21. The second slide rail 31 and the second drive mechanism 32 are both disposed on the second support frame 30. The second slide rail 31 extends along a second direction S, and the first support frame 20 is slidably disposed on the second support frame 30 via the second slide rail 31. The second drive mechanism 32 is connected to the first support frame 20 and is used to drive the first support frame 20 to reciprocate along the second slide rail 31. By driving the first adjustment mechanism 2 and the quick-change plate fixture 6, the position of the object being lifted relative to the lifting point can be changed, thereby adjusting the center of gravity of the entire structure of the object being lifted, the first adjustment mechanism 2 and the quick-change plate fixture 6, and realizing the tilt angle adjustment of the quick-change plate fixture 6 relative to the horizontal plane.

[0044] Compared to existing technologies that use cylinders or other drive structures to connect vertically to the object being lifted, the perpendicular design of the first adjustment mechanism 2 and the second adjustment mechanism 3 in this embodiment provides superior rigidity and eliminates concerns about damage to the drive structure due to excessive weight of the object being lifted. Furthermore, it effectively resists the torque generated by a heavy object during adjustment, preventing unexpected twisting of the quick-change disc fixture 6 during adjustment operations.

[0045] Furthermore, the adjustment components in the device provided in this embodiment adopt the aforementioned cross-shaped structural design. Compared to the prior art's method of adjusting posture using vertically arranged telescopic actuators, the device provided in this embodiment, when hoisting large components with significant weight, avoids power failure or decreased accuracy due to excessive weight because the movement directions of the first adjustment mechanism 2 and the second adjustment mechanism 3 are not in the same direction as the weight direction during the adjustment process. This ensures a stable and reliable adjustment process. Further, in this embodiment, both the first drive mechanism 22 and the second drive mechanism 32 are lead screw stepper motors. Lead screw stepper motors can convert the rotational motion of the motor into the linear motion of the lead screw nut, possessing excellent properties such as high precision and self-locking capability. This facilitates high-precision position locking during the adjustment process.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, the first connecting structure 1 in this embodiment is a cuboid connecting frame 10, and the connecting frame 10 is provided with a lifting ring 11 for connecting to the hoisting equipment. In this embodiment, the controller 4 is also installed in the internal area formed by the connecting frame 10. This facilitates the arrangement of the controller 4 and allows for the addition of counterweight through the controller 4, which is beneficial for improving the adjustment capability of the adjustment component. In this embodiment, the bottom of the second support frame 30 forms a second connecting structure. Specifically, a connecting crossbeam is provided at the bottom of the second support frame 30, and a suitable quick-change disc fixture 6 can be locked and fixed to the bottom of the second support frame 30 by locking screws.

[0047] It should be noted that different quick-change plate fixtures 6 can be selected according to different objects being lifted, in order to perform corresponding docking operations. At the same time, based on the lifting point position and center of gravity distribution of the object being lifted, the approximate tilt direction after lifting can be predicted in advance. Therefore, when installing the quick-change plate fixture 6, one end of the quick-change plate fixture 6 can be pre-installed near one end of the second support frame 30, which can increase the ability to adjust the components.

[0048] Combination Figure 4 and Figure 5As shown, in this embodiment, the first detection module 200 is mounted on the first support frame 20. The first detection module 200 is a tilt sensor, which can accurately monitor in real time the tilt angle of the first support frame 20, the second support frame 30 mounted on the first support frame 20, and the quick-change tray fixture 6 relative to the horizontal plane. In other optional embodiments, the first detection module 200 can also be mounted on the second support frame 30.

[0049] Using the above design, the first detection module 200 can detect the pose information of the quick-change tray fixture 6 in real time. The controller 4 determines whether the poses of the quick-change tray fixture 6 and the object being lifted meet the requirements based on the detected pose information. When a deviation is detected between the real-time pose of the quick-change tray fixture 6 and the target pose, the controller 4 controls the adjustment component to perform online adjustment and correction of the poses of the quick-change tray fixture 6 and the object being lifted until the real-time pose of the quick-change tray fixture 6 matches the target pose. In this embodiment, the target pose refers to the horizontal pose of the quick-change tray fixture 6 and the object being lifted. This achieves online pose closed-loop control for the lifting of large components during the installation process, improving the automation and reliability of the docking process.

[0050] Combination Figure 7 As shown, the process of operating the device provided in this embodiment will be described. For ease of distinction, the object to be lifted in this embodiment is referred to as the first object to be lifted 7. At the start of the operation, a suitable quick-change disc fixture 6 is first installed at the bottom of the second support frame 30. Figure 7 When the first docking surface 70 of the first object to be lifted 7 shown is horizontal, the controller 4, based on feedback from the first detection module 200, controls the adjustment component to operate, driving the first connecting structure 1 and the controller 4 to move along the first direction P, and driving the first adjustment mechanism 2, the first connecting structure 1, and the controller 4 to move along the second direction S, adjusting the quick-change tray fixture 6 to a horizontal state. Then, the lifting equipment drives the device and the quick-change tray fixture 6 to move directly above the first object to be lifted 7, and then controls the device to descend until the positioning pin on the quick-change tray fixture 6 aligns and inserts with the positioning hole on the docking surface of the first object to be lifted 7, thus achieving the docking operation between the quick-change tray fixture 6 and the first object to be lifted 7.

[0051] Next, the hoisting equipment moves the device, quick-change tray fixture 6, and the first object to be hoisted 7 together to be directly above the target component 9. During this movement, if necessary, the tilt angle of the quick-change tray fixture 6 can be adjusted again based on feedback from the first detection module 200 to ensure that the posture of the first object to be hoisted 7 meets the operational requirements. Finally, the control device lowers until the first object to be hoisted 7 is docked with the target component 9.

[0052] Example 2: This example also provides a device for online attitude adjustment of large components, such as... Figure 8 As shown, the device provided in this embodiment differs from the device provided in Embodiment 1 in that it further includes four sets of docking mechanisms 5. Specifically, the docking mechanism 5 includes a linear driver 50 disposed on the adjustment assembly and a docking connector 51 disposed on the output end of the linear driver 50. The linear driver 50 is used to drive the docking connector 51 to move to contact and position with the docking surface of the object being lifted, and to drive the quick-change tray fixture 6 positioned on the second connecting structure to move to dock with the object being lifted. That is, after the quick-change tray fixture 6 is adjusted to be parallel to the docking surface of the object being lifted, the linear driver 50 can drive the docking connector 51 to move to contact and position with the docking surface of the object being lifted. The contact and positioning refers to the fixing of the docking connector 51 and the docking surface of the object being lifted. In this embodiment, the docking connector 51 is a vacuum suction cup. When the vacuum suction cup contacts the docking surface of the object being lifted, it can be tightly attached to the docking surface by drawing a vacuum to form a negative pressure. Then the linear drive 50 performs a shortening operation. Since the connector 51 is positioned on the mating surface, the linear drive 50 can drive the device and the quick-change plate fixture 6 as a whole to move toward the object being lifted until the quick-change plate fixture 6 and the mating surface of the object being lifted are aligned.

[0053] By setting the docking mechanism 5, the quick-change plate tooling 6 can be stably docked with the object being hoisted, preventing the relative displacement of the quick-change plate tooling 6 and the object being hoisted due to the shaking of the connection structure between the hoisting equipment and the device.

[0054] It should be noted that, in other alternative embodiments, a magnetic connector 51 can also be used, as long as the mating surface of the object being lifted can magnetically engage with the magnetic connector. Additionally, in other alternative embodiments, the docking mechanism 5 can be configured in two or more sets.

[0055] Furthermore, the device provided in this embodiment also includes four sets of second detection modules 300. The second detection modules 300 are connected to the controller 4. The adjustment component is also configured to adjust the relative position between the first connecting structure 1 and the second connecting structure according to the detection information from the second detection modules 300 under the control of the controller 4, so as to adjust the quick-change tray fixture 6 to be parallel to the docking surface of the object being lifted. Setting the second detection modules 300 to cooperate with the aforementioned docking mechanism 5 can increase the applicability of this device, as detailed below:

[0056] Some of the objects being lifted may have their mating surfaces tilted relative to the horizontal plane due to factors such as a small top area or the orientation of their internal structures. To distinguish them from the first object being lifted 7 in Embodiment 1, the object being lifted in this embodiment is referred to as the second object being lifted 8. For example... Figure 9As shown, the second docking surface 80 of the second object being hoisted 8 is inclined relative to the horizontal plane. In this state, the quick-change tray fixture 6 needs to be adjusted to be parallel to the second docking surface 80. If it is difficult to achieve this using only the tilt sensor in Embodiment 1, the second detection module 300 in this embodiment can be used to detect whether the quick-change tray fixture 6 is parallel to the second docking surface 80, and the detection result can be fed back to the controller 4, which can then make corresponding adjustments to the adjustment components.

[0057] In this embodiment, the second detection module 300 is a laser sensor. Specifically, four sets of laser sensors are located at the four corners of the bottom of the second support frame 30. By detecting the distance between each of the four sets of laser sensors and the second mating surface 80, it can be determined whether the four corners of the second support frame 30 are parallel to the second mating surface 80, and thus whether the quick-change tray fixture 6 is parallel to the second mating surface 80. If they are not parallel, the adjustment components can be adjusted accordingly.

[0058] Similarly, the docking surface on the target component 9 that docks with the second hoisted object 8 may also be inclined relative to the horizontal plane. For this type of complex docking operation, precise docking can be achieved through the device provided in this embodiment.

[0059] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art should understand that this application includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this application will be included within the scope of the claims.
