Background Art

[0002] In industrial production, especially in the manufacturing and logistics industries, loading and flipping of products are common operations. In the assembly, testing and production process of solid rocket engines, the loading and flipping of engine casings are more frequent. Traditional methods mostly rely on manual or simple mechanical devices, which are not only inefficient, but also pose safety hazards, such as work-related accidents caused by heavy object handling or crane lifting. With the development of automation technology, the demand for efficient, safe and intelligent loading and flipping equipment in work is increasing. However, the products on the existing market often have problems such as complex structure, inconvenient operation and high cost, which make it difficult to meet the broad market demand.

[0003] After consulting relevant information, it is found that the existing small solid rocket engine shells are generally supported by fixed brackets during operation and flipped by crane lifting. The relevant automated load-bearing operation platforms are relatively few and not universal. In the article "An Automatic Flipping Device and Flipping Operation Method" published by Chengdu Guoruntong Technology Development Co., Ltd. with publication number CN118145292A, the flipping structure design makes it possible for the cylindrical product to be rotated only along its central axis and cannot be flipped in the direction perpendicular to the central axis.

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The present application embodiment discloses a solid rocket engine ultrasonic flaw detection loading and flipping platform, such as Figure 1 and Figure 2 As shown, it includes a loading platform, a fastening mechanism, a lifting mechanism and a control system. The loading platform is used to install the engine housing, the fastening mechanism is used to stably connect the engine housing to the loading platform; the lifting mechanism is connected to the bottom of the loading platform and is used to adjust the height of the loading platform.

[0034] like Figure 1 , Figure 5 As shown, the loading platform is used to support the product to be turned over, and the loading platform includes a support frame 8, a propulsion block 7, a flip disk 9, a flip motor 10 and a control system. The support frame 8 has a vertical installation through hole, and the flip disk 9 is connected to the installation through hole of the support frame 8 through a rotating shaft 13. The flip disk 9 is a cylindrical structure, so that the staff can operate or process the product installed on the flip disk 9 under the support frame 8. A plurality of bearing blocks 1 are fixedly connected to the inner side of the flip disk 9 for supporting the engine housing; the propulsion block 7 is connected to the flip disk 9 by sliding along the radial direction of the flip disk 9, and the propulsion block 7 is connected to the propulsion screw by rotation. The propulsion screw is threadedly connected to the flip disk 9. When the engine housing is placed on the bearing block 1 of the flip disk 9, the propulsion screw is rotated, and the propulsion screw drives the propulsion block 7 to tighten the engine housing to fix the product. The flip motor 10 is fixedly connected to the support frame 8, and the output shaft of the flip motor 10 is used to drive the flip disk 9 to rotate, and the rotation of the flip disk 9 is realized by precise control; the control system is responsible for the precise automatic operation of the flip action. At least four support screws 3 are fixedly connected to the bottom of the support frame 8.

[0035] like Figure 3 , Figure 6 and Figure 8As shown, the support frame 8 is also threadedly connected with a locking pin 2. When the flip plate 9 is rotated to a horizontal state, the locking pin 2 is rotated, and the end of the locking pin 2 is pressed against the flip plate 9, thereby ensuring the position stability of the flip plate 9 in a horizontal state.

[0036] like Fig. 9 As shown, the fastening mechanism: the fixing mechanism also includes a fastening mechanism, which includes a snap block 15, a push spring 16 and a stroke tube 14, and the engine is provided with a supporting portion that cooperates with the snap block 15; the bottom of the bearing block 1 protrudes toward the side close to the axis of the flip disk 9 to form an L shape, and the stroke tube 14 is fixedly connected to the bearing block 1 and is located above the protrusion at the bottom of the bearing block 1, one end of the push spring 16 is connected to the bottom of the stroke tube 14, and the other end extends out of the stroke tube 14 and is connected to the snap block 15, and the snap block 15 is slidably connected to the stroke tube 14 along the axis direction of the stroke tube 14, and the side of the snap block 15 facing the axis of the flip disk 9 is an inclined surface, and along the direction close to the protrusion at the bottom of the bearing block 1, the inclined surface gradually tilts toward the direction close to the axis of the flip disk 9; when the engine is lowered for loading, the snap block 15 is pushed to automatically move backward, and the push spring 16 shrinks to the stroke tube 14. After the engine is loaded on the bearing block 1, the snap block 15 is pushed by the push spring 16 to clamp the engine support portion to ensure that the engine does not move up and down. The spring locking device is used to automatically lock after the engine is placed to prevent the product from accidentally falling or moving.

[0037] like Figure 4 and Figure 7 As shown, the lifting mechanism includes a disc base 12, a support rod 4, a transmission gear structure 5, a transmission shaft 6 and a transmission motor 11. Four transmission gear structures 5 are arranged in sequence along the circumference of the disc base 12. Each transmission gear structure 5 includes a box body, a turbine is vertically rotatably connected in the box body, and the turbine is fixedly connected to the support rod 4. The support rod 4 is sleeved outside the support screw 3 and is threadedly connected to the support screw 3. The rotation of the turbine drives the support screw 3 to vertically lift and lower; two transmission shafts 6 are arranged, one transmission shaft 6 is connected between the two boxes, and the other transmission shaft 6 is connected between the other two boxes, and the transmission shaft 6 is rotatably connected to the box body. The two end parts of each transmission shaft 6 are worm structures, and the worm structure of the transmission shaft 6 is meshed with the turbine; a driving shaft is rotatably connected between a box body at one end of a transmission shaft 6 and a box body at one end of another transmission shaft 6, and a support shell is connected between the two boxes. The drive shaft and the end of the transmission shaft 6 are driven by a bevel gear. A transmission motor 11 is fixedly connected to the support shell, and the transmission motor 11 is used to drive the drive shaft to rotate. The transmission motor 11 is used to synchronously drive the four support rods 4 to rotate synchronously, thereby driving the support screw rod 3 to rise and fall.

[0038] The present invention realizes the lifting process of the engine housing by pushing the loading platform mechanism through the screw transmission. The lifting drive structure is driven by the transmission motor 11, and the power is transmitted to the transmission shaft 6 through the internal bevel gear of the transmission structure. The transmission of the worm gear is used to rotate the turbine inside the transmission structure 5, driving the screw 3 to make axial movement inside the support rod 4. The center of the turbine is a threaded structure, which is equivalent to the nut of the lifting screw, and is matched with the lifting screw. The screw is movable and the turbine is fixed. The design of the screw thread makes each rotation correspond to a certain displacement. By changing the number of rotations of the motor or adjusting the motor speed, precise lifting and lowering control can be achieved. At the same time, the guiding cooperation between the support screw 3 and the support rod 4 ensures that the screw maintains linear motion during the rising or falling process to prevent shaking.

[0039] The rotation of the flip plate 9 is driven by the flip motor 10, and the flipping action of the flip plate 9 is realized through a precise reducer and a transmission device. The flip motor 10 has the characteristics of high precision and high response speed, and can ensure the smoothness and accuracy of the flipping action. The control system controls the operation of the servo motor through a preset program or real-time instructions to realize the precise flipping of the flip frame.

[0040] Safety protection: The platform is equipped with limit switches, overload protection and other safety devices to prevent abnormal situations such as overload and over-limit during the flipping process. At the same time, the control system also has an emergency stop function to ensure that the equipment can be stopped quickly in an emergency.

[0041] The operation process is divided into the following stages:

[0042] 1 Preparation stage: The operator first places the product to be flipped on the load-bearing platform, inserts the latch into the hole or slot on the product through the operating handle, and fixes the latch with the spring locking device. Then, start the control system and set parameters such as the flip angle.

[0043] 2. Flipping stage: After receiving the flipping command, the control system starts the servo motor. The servo motor drives the flip frame to rotate around the axis to a preset angle through the reducer and transmission device. During the flipping process, the control system monitors the operating status of the servo motor and the position information of the flipping frame in real time to ensure the smooth and accurate flipping action.

[0044] 3. Lifting and lowering stage: Click the lifting and lowering button on the control system to realize real-time start and stop or lifting and lowering operations at a predetermined angle through the servo motor drive.

[0045] 4 Reset stage: After the operation is completed, the control system can control the servo motor to reverse and reset the flip frame to its initial position. At the same time, the operator can manually pull out the pin and remove the product for the next operation.
