[0033] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the implementation of this application will be described in more detail below in conjunction with the drawings in the implementation of this application. In the drawings, the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. The described implementation is a part of the implementation of this application, not all of the implementations. The implementation described below with reference to the drawings is exemplary and is intended to be used to explain this application, and should not be understood as a limitation on this application. Based on the implementation in this application, all other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The implementation of this application is described in detail below in conjunction with the drawings.

[0034] This application provides a wing flipping device, such as Figures 1-19 As shown, it mainly includes: The frame 1 includes a base 102 and a vertical beam 107 located on the base 102; The bottom end of the slide rail 2 is hinged to the base 102 of the frame 1, and the top end is connected to the top end of the vertical beam 107 through a spiral transmission structure. The slide rail 2 is provided with a slideway extending from the bottom end to the top end; The guide wheel 15 is slidably arranged in the slideway of the slide rail 2; The reducer 3 is fixed on the guide wheel 15. The reducer 3 includes a first rotating mechanism, a second rotating mechanism and a shifting mechanism 348. The first rotating mechanism includes a large worm gear shaft 302 driven by a large gear 331, and the second rotating mechanism includes a small worm gear shaft 324 driven by a small gear 336. The shifting mechanism 348 has a handle at one end and a gear 345 at the other end. The handle pushes the gear 345 to engage with the large gear 331 or the small gear 336. The gear 345 is also connected to a spline shaft 341 via a spline. The spline shaft 341 is connected to the output shaft of the motor 17. The connecting frame 6 has one end connected to the large worm gear shaft 302 of the reducer 3 and the other end has an interface for connecting to the wing; One end of the steel cable 4 is connected to the housing 301 of the reducer 3, and the other end passes through the large pulley assembly 10 set at the top of the slide rail 2, and is connected to and wound on the roller 7 set on the housing of the reducer 3. The roller 7 is connected to the small worm gear shaft 324 of the reducer 3.

[0035] The present application fixes the wing through a connecting frame 6, and the connecting frame 6 and the reducer 3 are fixed on the guide wheel 15 together. After the small gear 336 is rotated by the shifting mechanism 348 in the reducer 3, the reducer 3 and the guide wheel 15 can be driven to slide up and down in the slide rail 2, that is, the wing can be driven to move up and down. After the large gear 331 is rotated by the shifting mechanism 348 in the reducer 3, the connecting frame 6 at the front end of the reducer 3 can be driven to rotate, that is, the wing can be driven to flip. The spiral transmission structure at the top of the slide rail 2 can drive the slide rail 2 to deflect, that is, it can drive the wing to deflect up or down around the connection point. The above method ensures all-round motion control of the wing. When flipping the wing or cleaning the wing fuel tank, the operation is simple, safe and reliable.

[0036] In some optional embodiments, the base 102 of the frame 1 is connected to the traction rod 101 , and a plurality of universal wheels are provided at the bottom of the base 102 .

[0037] like Figures 1 to 4 As shown, the frame 1 consists of a traction rod 101, a base 102, a fixing plate 103, a support 104, a stud 105, a nut 106 and a vertical beam 107. The base 102 is welded from square steel and sheet metal. There are two universal wheels on the left side. The traction rod 101 is installed on the left side to adjust the direction of traction. Two fixed wheels are installed on the right side. The bottom of the base 102 is in the shape of a "only" Figure 3 The left end of Figure 1 There is a vertical beam 107 at the right end of the middle, and a fixed support 104 is welded to the upper end of the vertical beam 107. The vertical plates at both ends of the support 104 are threaded holes for installing a spiral transmission structure.

[0038] In some optional embodiments, two fixing plates 103 are fixedly connected to the base 102, a stud bolt 105 is installed between the two fixing plates 103, and a sleeve 204 that can be sleeved on the middle polished rod of the stud bolt 105 is provided at the bottom of the slide rail 2.

[0039] In this embodiment, reference Figure 4 、 Figure 5 、 Figure 6 , there is a mounting hole on the fixing plate 103, and the stud 105 is installed through the nut 106. The stud 105 is sleeved on the sleeve 204 of the slide rail 2 to realize the deflection of the slide rail 2 around the axis where the stud 105 is located. The slide rail 2 is welded by the ear 201, the bracket 202, the ear 203, and the sleeve 204. The bracket 202 is welded into a rectangular structural member by channel steel, and the inside of the channel steel on both sides serves as a slideway. The ear 203 is welded to both sides of the lower end of the bracket 202, and the sleeve 204 is welded between the ear 203. The slide rail 2 is installed on the stud 105 through the inner hole of the sleeve 204, so that the slide rail can rotate around the stud 105. The ear 201 is welded to the upper end of the bracket 202, as shown Figure 6 As shown, there are two sets of lugs. One set is used to install the large pulley assembly 10, which drives the reducer up and down based on the steel cable 4. The other set is used to horizontally install the shaft sleeve 11 of the spiral transmission structure through bolts. The left end of the shaft sleeve 11 has an internal trapezoidal thread, and the right end has a hole and a through hole for installing the bolt. The shaft sleeve 11 can rotate around the bolt.

[0040] In some optional embodiments, the spiral transmission structure includes a screw assembly 12 and a sleeve 11. The screw assembly 12 includes a screw 121. One end of the screw 121 passes through a bearing seat 125 hinged to the top of the vertical beam 107 and is connected to the ratchet wrench 13. The other end of the screw 121 passes into the sleeve 11 and is threadedly connected to the sleeve 11. The other end of the sleeve 11 is hinged to the top of the slide rail 2.

[0041] refer to Figure 1 and Figure 7 The screw assembly 12 is composed of a screw 121, a thrust ball bearing 122, an oil filling cup 123, a washer 124, a bearing seat 125, and a first locking nut 126. Figure 7 In the figure, the right side of the screw rod 121 is a threaded rod with a trapezoidal thread, which is threadedly connected to the sleeve 11. The outside of the left side has an external thread to install the first locking nut 126, and the left end has a threaded hole, on which the ratchet wrench 13 can be installed through a bolt. The thrust ball bearing 122 and the washer 124 are installed in the holes on the left and right ends of the bearing seat 125, and the oil filling cup 123 is installed in the threaded hole at the upper end. The bearing seat 125 is installed on the step surface at the left end of the screw rod 121, and the axial position of the bearing seat 125 is locked by the first locking nut 126. The bearing seat 125 is then installed in the middle of the upper plate of the support 104, and the positioning screw 14 is screwed into the threaded hole of the support 104, and then screwed into the hole in the front and rear directions of the bearing seat 125 to limit the rotation of the bearing seat 125. It can be understood that when the ratchet wrench 13 is rotated, the screw 121 rotates. Since the sleeve 11 cannot rotate, the screw 121 and the sleeve 11 constitute a spiral transmission structure, which causes the screw 121 and the sleeve 11 to be relatively shortened or elongated, thereby controlling the rotation position of the slide rail 2 relative to the stud bolt 105, thereby realizing the overall deflection control of the slide rail 2.

[0042] In this embodiment, the ratchet wrench 13 is rotated to control the rotation angle of the slide rail 2. The reducer 3 is mounted on the slide rail 2 and rotates synchronously. The connecting frame 6 is mounted on the reducer 3, and the rotation axis of the connecting frame 6 is perpendicular to the end face of the slide rail 2. The tilt angle of the connecting frame 6 is adjusted to facilitate wing flipping. This embodiment optimizes the height of the slide rail 2 of the wing flipping device. If the wing is flipped in a horizontal position, the slide rail 2 needs to be designed to be extremely high, which is inconvenient to use.

[0043] In some optional embodiments, the guide wheels 15 include two sets, each set of guide wheels 15 includes a wheel axle 155, and the two ends of the wheel axle 155 are rotatably connected to the guide wheels 151.

An upper cover 312 is bolted to the opening to seal the box body. The support leg 30101 and the rectangular steel bar 30110 are welded to the lower left corner of the outer side of the box. A clamp 305 is welded to the lowermost contact point of the support leg 30101 and the rectangular steel bar 30110. A clamp 305 is also welded to the upper left corner of the outer left side of the box. The clamp 305 is bolted to the guide wheel 15, enabling the reducer 3 to slide on the slide rail 2. A pad 30112 is welded to the upper center of the bottom of the box. A support frame 30109 is welded below the pad 30112. The support arm 30103 is welded to the upper left portion of the outer side of the box. The front bearing seat 30102 is located at the left end of the support arm 30103 and the upper end of the support leg 30101. A cable connecting plate 30116 is welded to the support arm 30103 to secure one end of the cable 4. The left bearing seat 30114 is welded to the left of the center of the inner wall of the box-shaped part, and the right bearing seat 30115 is welded to the right of the center. There is a through hole in the center of the left side of the box-shaped part.

[0049] The large worm gear shaft 302 is mounted horizontally on the housing 301, supported in the middle by the front bearing seat 30102. A first tapered roller bearing 304 is mounted within the front bearing seat 30102 and secured with a screw-fastened baffle 303. The rightmost end of the large worm gear shaft 302 is mounted within the left bearing seat 30114, which houses a second tapered roller bearing 315. A first round nut 313 and a first retaining washer 314 are installed to the right of the second tapered roller bearing 315, providing a locking mechanism. The large worm gear 310 is mounted to the right of the large worm gear shaft 302 and the left end of the left bearing seat 30114. It is secured by a first retaining ring 308, a first flat key 309, and a shaft spring collar 311. The first transparent cover 306 is screwed to the point where the large worm gear shaft 302 meets the left hole of the box-shaped component. The first transparent cover 306 contains a first dustproof gasket 307. The left end of the large worm gear shaft 302 has a keyway and a threaded hole, which is connected to the connecting frame 6.

[0050] The small worm gear shaft 324 has keyways at both ends, and its left end is supported by the right bearing seat 30115. A third tapered roller bearing 318 is mounted within the right bearing seat 30115 and secured by a second round nut 316, a second retaining washer 317, and a second retaining ring 319. The small worm gear 320 is mounted on the right end of the small worm gear shaft 324, to the right of the second retaining ring 319, and secured by a fifth flat key 349. A second sleeve 321 is mounted on the right end of the small worm gear 320. To the right of the second sleeve 321 is a second transparent cover 323, screwed into the center hole on the right side of the box-shaped member. The second transparent cover 323 houses a fourth tapered roller bearing 322 and a second dustproof pad 325. The right side of the small worm gear shaft 324 extends out of the box-shaped member and has a slot and threads for threaded connection to the roller 7.

[0051] On the front of the box, two circular holes are located on the lower left and right sides for mounting a small worm 333 and a large worm 339, respectively. The worms are installed with their axes oriented forward and backward. Two corresponding mounting holes are located on the rear of the box. The worms are mounted by screwing a cover at the front and an end cap at the rear. These holes contain tapered roller bearings to ensure rotation. A portion of the worm protrudes from the end of the cover and connects to a socket wrench 5, which is rotated by turning the socket wrench 5. When assembled, the large worm 339 forms a worm-gear mechanism with the large worm wheel 310. When assembled, the small worm 333 forms a worm-gear mechanism with the small worm wheel 320. A large gear 331 is mounted at the rear end of the large worm 339, near the rear inner side of the box. A small gear 336 is mounted at the rear end of the small worm 333, near the rear inner side of the box. The end face of the small gear 336 faces in front of the large gear 331. At the back of the box-shaped part, a mounting hole is set between the worm mounting holes for mounting a spline shaft 341. The front of the spline shaft is fixed to the support frame 30109, and the back is connected to the motor 17 through the coupling 16. A gear 345 is installed in the middle of the spline shaft 341, which is fitted with a spline in a sliding manner.

[0052] The upper front portion of the box-shaped member has a mounting hole for the shift mechanism 348. The shift mechanism 348 is connected to the upper portion of the reversing mechanism 340 via a nut, and the center of the reversing mechanism is locked onto the shaft of gear 345. The shift mechanism 348, reversing mechanism 340, and gear 345 form a motion mechanism. The shift mechanism 348 has three gear positions. When the handle of the shift mechanism 348 is pushed forward, gear 345 moves forward and contacts the large gear 331. When the motor rotates, it drives the spline shaft 341, which in turn drives gear 345, which in turn drives the large gear 331, which in turn drives the large worm 339, which in turn drives the large worm gear 310, and finally the large worm gear shaft 302, thereby driving the connecting frame 6 to rotate and causing the wings to flip. When the shift mechanism 348 is in the neutral position, gear 345 is not in contact with the large gear 331 or the pinion 336, and the mechanisms do not rotate. When the handle of the shift mechanism 348 is pushed backward, the gear 345 moves backward and contacts the small gear 336. When the motor rotates, it eventually drives the small worm gear shaft 324 to rotate. When the small worm gear shaft 324 rotates, it pulls or releases the steel cable, driving the entire reducer 3 to move up and down along the slide rail.

[0053] In some optional embodiments, one end of the connecting frame 6 with the interface is forked to form two branches, one branch includes a tube 602 and an upper connecting member 601 located at the end of the tube 602, and the other branch includes a lower connecting member 604, the upper connecting member 601 is connected to one ear of the wing through a long pin 606, and the lower connecting member 604 is connected to another ear of the wing through a short pin 605.

[0054] like Figure 15 and Figure 16 As shown, the connecting frame 6 is a Y-shaped structure located on the left side of the reducer 3. It consists of an upper connecting piece 601, a tube 602, a barrel 603, a lower connecting piece 604, a short pin 605, and a long pin 606. The barrel 603 has a keyway on its left end and is mounted on the left end of the large worm gear shaft 302 on the reducer 3. The large worm gear shaft 302 has a keyway and a threaded hole on its left end. By locking the ends of the transverse key 18 into the keyways of the barrel 603 and the large worm gear shaft 302, installing the retaining plate 19, and tightening the bolts, the transverse key 18 is locked, securing the connecting frame 6 and the large worm gear shaft 302 together. When the large worm gear shaft 302 rotates, the connecting frame 6 also rotates. The upper connecting piece 601, tube 602, cylinder 603, and lower connecting piece 604 are welded together. The upper connecting piece 601 and the lower connecting piece 604 are connected to the ears of the wing and fixed by the short pin 605 and the long pin 606. There are fuse holes on the heads of the short pin 605 and the long pin 606, which are insulated after installation.

[0055] In some optional embodiments, a small pulley assembly 9 is provided on the housing 301 of the reducer 3 for steering the steel cable 4 led down from the large pulley assembly 10 .

[0056] In this embodiment, Figure 1 As shown, the steel cable 4 is led down from the large pulley assembly 10, turned by two small pulley assemblies 9, and then wound onto the drum 7. The drum 7 is driven to rotate by the reducer 3 to realize the retraction and extension control of the steel cable.

[0057] The structure of the roller 7 is as follows Figure 17 and Figure 18 As shown, the outer cylinder 704 is welded together by a first stopper 701, a second stopper 702, an outer cylinder 703, an inner cylinder 704, and a wedge 705. The first stopper 701 and the second stopper 702 are welded to both ends of the outer cylinder 703. The outer cylinder 703 is sleeved outside the inner cylinder 704. The outer cylinder 703 has an annular spiral groove on its surface for winding the steel cable 4. Before winding the steel cable 4, the end of the steel cable 4 is fixed by the wedge 705. The inner cylinder 704 is provided with threads and is connected to the right end of the small worm gear shaft 324 through threads. The second locking nut 20 and the third stop washer 21 are then installed to lock it, so that the small worm gear shaft 324 and the drum 7 rotate synchronously.

[0058] The small pulley assembly 9 of the present application is mounted on the upper left and right sides of the housing 301 of the reducer 3. Its structure is similar to that of the large pulley assembly 10 and is secured by screws. One end of the steel cable 4 is fixed to the drum 7 via a wedge 705. The cable is then wound around the drum 7, diverted upward through the first small pulley assembly, diverted leftward through the second small pulley assembly, passed upward through the large pulley assembly 10, and then downward through the hole in the support arm 30103, where it is secured with a cable clamp 22. When the small worm 333 rotates, the small worm gear shaft 324 rotates, and the drum 7 rotates, winding the cable and causing it to move up and down, driving the reducer 3 and the connecting frame 6 up and down.

[0059] The reducer 3 of the present application can be driven by an electric motor or manually. When driven by an electric motor, an electrical component 8 is provided. Figure 3 and Figure 19 As shown, electrical assembly 8 consists of a plug 801, a first waterproof cable 802, a circuit breaker 803, an electrical wire 804, a forward / reverse remote control switch 805, a second waterproof cable 806, and a motor 17, all connected in sequence. It is mounted behind the housing 301 of the reducer 3. When manually actuated, as previously described, the two worm gears protrude from the end face of the reducer 3's cover, allowing them to be connected to a socket wrench 5, which allows the two worm gears to be manually driven.

[0060] The wing's rotational speed during flapping is calculated using the following assumptions: motor 17 speed n = 1000 R / min, gear 345 teeth number Z1 = 17, large gear 331 teeth number Z2 = 85, and large worm gear 310 teeth number Z3 = 126. The calculated wing rotational speed is approximately 1.5 R / min. When powered, the wing rotates 1.5 times per minute, which is ergonomic and facilitates control of the wing's angle during flapping.

[0061] To calculate the vertical movement speed V of reducer 3, first calculate the rotational speed of drum 7. Gear 345 has 17 teeth (Z1), pinion 336 has 60 teeth (Z4), and worm gear 320 has 48 teeth (Z5). The diameter d of drum 7 is 100 mm, and the drum circumference is approximately 314 mm. Based on this, the vertical movement speed V of reducer 3 is approximately 15.7 mm / s. The reducer 3 moves 15.7 mm per second, which is ergonomic and convenient for controlling the vertical movement distance of reducer 3.

[0062] Based on the above-mentioned wing flipping device, the present application can realize the wing flipping and wing tank cleaning functions with or without power supply. The details are as follows.

[0063] (1) With power on, flip the wings on the bracket.

[0066] Step 4: Push out the wing flipping device and turn the ratchet wrench 13 to make the slide rail 2 form an acute angle of about 60° with the horizontal plane. At this time, the rotation axis of the connecting frame 6 is tilted upward by 30°. Control the forward and reverse remote control switch 805 to the positive direction, and then control the connecting frame 6 to move upward so that the wing will not touch the ground when flipping. Then, turn the forward and reverse remote control switch 805 to the middle disconnected position.

[0068] Step 6: Push the wing-flipping device toward the bracket until the wing is above the bracket. Push the handle of the shift mechanism 348 backward to the rear position, reverse the forward / reverse remote control switch 805, and then control the connecting frame 6 to move downward. When the lower surface of the wing approaches the upper surface of the bracket, control the forward / reverse remote control switch 805 to the intermediate disconnect position.

[0071] Step 3: Push the wing flipping device toward the wing, align the mounting holes, install the short pin 605 and the long pin 606, and secure them.

[0072] Step 4: Turn the ratchet wrench 13 to make the slide rail 2 form an acute angle of approximately 60° with the horizontal plane. At this time, the rotation axis of the connecting frame 6 is tilted upward by 30°. Use the socket wrench 5 to turn the small worm 333 on the right side clockwise to control the upward movement of the connecting frame 6 so that the wing does not touch the ground when it flips.

[0073] Step 5: Push the handle of the shift mechanism 348 forward to the forward position, use the socket wrench 5 to rotate the large worm 339 on the left clockwise or counterclockwise to flip the wing 180 degrees, and turn the ratchet wrench 13 to make the slide rail 2 vertical. At this time, the wing is horizontal.

[0074] Step 6: Push the wing-flipping device toward the bracket until the wing is above it. Push the handle of the shift mechanism 348 backward to the rear position. Use the socket wrench 5 to rotate the small worm gear 333 on the right side counterclockwise to control the downward movement of the connecting frame 6. When the lower surface of the wing approaches the upper surface of the bracket, stop the rotation. Remove the fuse and the short and long pins 605 and 606. Lower the wing onto the bracket to complete the wing flip.

[0075] (3) When there is power, clean the fuel tank of the wing on the bracket.

[0078] Step 4: Push out the wing flipping device and turn the ratchet wrench 13 to make the slide rail 2 form an acute angle of about 60° with the horizontal plane. At this time, the rotation axis of the connecting frame 6 is tilted upward by 30°. Then control the forward and reverse remote control switch 805 to the positive direction, thereby controlling the connecting frame 6 to move upward so that the wing will not hit the ground when flipping. Then, turn the forward and reverse remote control switch 805 to the middle disconnected position.

[0079] Step 5: Fill the wing tank with cleaning fluid, install the plug cap, push the handle of the shift mechanism 348 forward to the forward position, and control the forward and reverse remote control switch 805 to rotate the wing continuously. The cleaning fluid flows through the tank and completes the cleaning process. After a period of time, return the forward and reverse remote control switch 805 to the intermediate disconnect position, open the plug cap, and pump out the cleaning fluid using the pumping unit. Turn the ratchet wrench 13 to verticalize the slide rail 2, so that the wing is horizontal.
