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 combination with the drawings.

[0040] The present application provides a wing flipping device, such as Figure 1-Figure 19 As shown, it mainly includes:

[0041] The frame 1 includes a base 102 and a vertical beam 107 located on the base 102;

[0042] The slide rail 2 has a bottom end hinged on the base 102 of the frame 1, and a top end 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;

[0043] A guide wheel 15 is slidably arranged in the slideway of the slide rail 2;

[0044] 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. One end of the shifting mechanism 348 is a handle, and the other end is connected to a gear 345. 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 through a spline, and the spline shaft 341 is connected to the output shaft of the motor 17.

[0045] A connecting frame 6, one end of which is connected to the large worm gear shaft 302 of the reducer 3, and the other end of which has an interface for connecting to the wing;

[0046] The steel cable 4 has one end connected to the housing 301 of the reducer 3, and the other end passes through the large pulley assembly 10 arranged at the top of the slide rail 2, and is connected to and wound on the drum 7 arranged on the housing of the reducer 3, and the drum 7 is connected to the small worm gear shaft 324 of the reducer 3.

[0047] The present application fixes the wing via a connecting frame 6, and the connecting frame 6 is fixed on the guide wheel 15 together with the reducer 3. 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, and the operation is simple, safe and reliable when flipping the wing and cleaning the wing tank.

[0048] 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 disposed at the bottom of the base 102 .

[0049] like Figures 1 to 4 As shown, the frame 1 is composed of a traction rod 101, a base 102, a fixing plate 103, a support 104, a stud bolt 105, a nut 106 and a vertical beam 107. The base 102 is welded by square steel and sheet metal. There are two universal wheels on the left. 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 a "only"-shaped structure. 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 on 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.

[0050] In some optional embodiments, two fixing plates 103 are fixedly connected to the base 102 , stud bolts 105 are installed between the two fixing plates 103 , and a sleeve 204 that can be sleeved on the middle polished rod of the stud bolts 105 is provided at the bottom of the slide rail 2 .

[0051] 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 and formed by the ear 201, the bracket 202, the ear 203, and the sleeve 204. The bracket 202 is welded by channel steel into a rectangular structural member, 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 pieces 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, such as Figure 6 As shown, there are two sets of lugs, one set is used to install the large pulley assembly 10, so as to drive the reducer to move up and down based on the steel cable 4, and the other set is used to horizontally install the sleeve 11 of the spiral transmission structure through bolts, the left end of the sleeve 11 is an internal trapezoidal thread, and the right end is a hole and a through hole for installing the bolt. The sleeve 11 can rotate around the bolt.

[0052] 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 at the top of the vertical beam 107, and is connected to a ratchet wrench 13, the other end of the screw 121 passes through the sleeve 11 and is threadedly connected to the sleeve 11, and the other end of the sleeve 11 is hinged at the top of the slide rail 2.

[0053] 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 outer part of the left side has an external thread to install the first locking nut 126, and the left end has a threaded hole, through which the ratchet wrench 13 can be installed by bolts. The thrust ball bearing 122 and the washer 124 are installed in the holes at 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. Then install the bearing seat 125 in the middle of the upper plate of the support 104, screw it into the threaded hole of the support 104 through the positioning screw 14, and then screw it 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 achieving overall deflection control of the slide rail 2.

[0054] 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 surface of the slide rail 2. The tilt angle of the connecting frame 6 is adjusted to facilitate the wing flipping. This embodiment optimizes the height of the slide rail 2 of the wing flipping device. If the wing flips in a horizontal state, the slide rail 2 needs to be designed to be particularly high, which is inconvenient to use.

[0055] In some optional embodiments, the guide wheels 15 include two sets, each set of guide wheels 15 includes an axle 155, and the two ends of the axle 155 are rotatably connected to guide wheels 151, and the guide wheels 151 can slide in the slideway of the slide rail 2.

The support arm 30103 is welded to the upper left part of the outer side of the box-shaped part. 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. The cable connecting plate 30116 is welded to the support arm 30103 and is used to fix one end of the cable 4. The left bearing seat 30114 is welded to the left of the middle of the inner wall of the box-shaped part, and the right bearing seat 30115 is welded to the right of the middle. A through hole is provided in the middle of the left side of the box-shaped part.

[0061] The large worm gear shaft 302 is horizontally mounted on the box body 301, and the middle position is supported by the front bearing seat 30102. The first tapered roller bearing 304 is installed in the front bearing seat 30102, and the baffle 303 is locked by screws. The rightmost end of the large worm gear shaft 302 is installed in the left bearing seat 30114, and the left bearing seat 30114 has a second tapered roller bearing 315. The first round nut 313 and the first stop washer 314 are installed on the right side of the second tapered roller bearing 315 to play a locking role. The large worm gear 310 is installed at the right end of the large worm gear shaft 302 and the left end of the left bearing seat 30114, and is fixed by the first retaining ring 308, the first flat key 309, and the shaft spring clamp 311. The first transparent cover 306 is fixed by screws at the contact point between the large worm gear shaft 302 and the left hole of the box-shaped part, and the first transparent cover 306 has a first dustproof pad 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.

[0062] The small worm gear shaft 324 has keyways at both ends, and the left end is supported by the right bearing seat 30115. The third tapered roller bearing 318 is installed in the right bearing seat 30115 and locked by the second round nut 316, the second stop washer 317, and the second retaining ring 319. The small worm gear 320 is installed on the right end of the small worm gear shaft 324, and is fixed by the fifth flat key 349 on the right side of the second retaining ring 319. The second sleeve 321 is installed on the right end of the small worm gear 320. The right end of the second sleeve 321 is the second transparent cover 323, which is fixed to the hole in the middle of the right side of the box-shaped part by screws. The second transparent cover 323 contains the fourth tapered roller bearing 322 and the second dustproof pad 325. The right side of the small worm gear shaft 324 extends out of the box-shaped part, with a slot and a thread, and is connected to the roller 7 by a thread.

[0063] In front of the box-shaped part, there are two round holes on the left and right sides of the lower part for installing the small worm 333 and the large worm 339 respectively. When the worm is installed, the axis is in the front-to-back direction. There are also two corresponding mounting holes on the back of the box-shaped part. The worm is installed by fixing the transparent cover with screws at the front of the box-shaped part and fixing the end cover with screws at the back. The tapered roller bearing is installed inside to ensure that the worm can rotate. A part of the worm protrudes from the end face of the transparent cover and is connected to the socket wrench 5. The worm is rotated by rotating the socket wrench 5. After the large worm 339 is assembled, it forms a worm-gear mechanism with the large worm wheel 310. After the small worm 333 is assembled, it forms a worm-gear mechanism with the small worm wheel 320. At the rear end of the large worm 339, close to the inner rear of the box-shaped part, a large gear 331 is installed. At the rear end of the small worm 333, close to the inner rear of the box-shaped part, a small gear 336 is installed. The end face of the small gear 336 is in front of the large gear 331. At the back of the box-shaped part, there is a mounting hole 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 assembled with the spline sliding fit.

[0064] A mounting hole is provided on the upper part of the front of the box-shaped part for mounting the shift mechanism 348. The shift mechanism 348 is connected to the upper part of the reversing mechanism 340 through a nut, and the middle of the reversing mechanism is locked on the shaft of the gear 345. The shift mechanism 348, the reversing mechanism 340, and the gear 345 form a motion mechanism. The shift mechanism 348 has three gears. When the handle of the shift mechanism 348 is pushed forward, the gear 345 moves forward and contacts the large gear 331. When the motor rotates, it drives the spline shaft 341 to rotate, drives the gear 345 to rotate, drives the large gear 331 to rotate, drives the large worm 339 to rotate, drives the large worm wheel 310 to rotate, and finally drives the large worm wheel shaft 302 to rotate, thereby driving the connecting frame 6 to rotate and driving the wing to flip. When the shift mechanism 348 is in the middle position, the gear 345 does not contact the large gear 331 and the small gear 336, and each mechanism does not rotate. When the handle of the shift mechanism 348 is pushed backward, the gear 345 moves backward and contacts the pinion 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.

[0065] 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.

[0066] like Fig.15 and Fig.16 As shown, the connecting frame 6 is a Y-shaped structure, located on the left side of the reducer 3, and is composed of an upper connecting piece 601, a tube 602, a barrel 603, a lower connecting piece 604, a short pin 605, a long pin 606, etc. The barrel 603 has a keyway at the left end, which is installed 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 at the left end. By clamping the two ends of the transverse key 18 in the keyways of the barrel 603 and the large worm gear shaft 302, and then installing the baffle 19, tightening the bolts to lock the transverse key 18, the connecting frame 6 and the large worm gear shaft 302 are fixed together. When the large worm gear shaft 302 rotates, the connecting frame 6 also rotates. The upper connecting piece 601, the tube 602, the cylinder 603, and the 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 shaft 605 and the long pin shaft 606. There are fuse holes at the heads of the short pin shaft 605 and the long pin shaft 606, and the fuses are installed after installation.

[0067] 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 .

[0068] In this embodiment, if Figure 1 As shown, after the steel cable 4 is led down from the large pulley assembly 10, it is 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 release control of the steel cable.

[0069] The structure of the drum 7 is as follows Fig.17 and Fig.18 As shown, the first stopper 701, the second stopper 702, the outer cylinder 703, the inner cylinder 704, and the wedge block 705 are welded and formed. The first stopper 701 and the second stopper 702 are welded at 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 block 705. The inner cylinder 704 is provided with a thread, which is connected to the right end of the small worm gear shaft 324 through a thread, and then the second locking nut 20 and the third stop washer 21 are installed to lock it, so that the small worm gear shaft 324 and the drum 7 rotate synchronously.

[0070] The small pulley assembly 9 of the present application is installed on the upper left and right sides of the housing 301 of the reducer 3. The structure is similar to the large pulley assembly 10 and is fixed by screws. One end of the steel cable 4 is fixed to the drum 7 through the wedge block 705, and then wound on the drum 7, and then turned upward through the first small pulley assembly, turned left through the second small pulley assembly, passed through the large pulley assembly 10 upward, and then passed through the hole of the support arm 30103 downward, and locked with the steel cable clip 22. When the small worm 333 rotates, the small worm gear shaft 324 rotates, the drum 7 rotates, and the steel cable is wound, so that the steel cable moves up and down, driving the reducer 3 and the connecting frame 6 to move up and down.

[0071] 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 Fig.19 As shown, the electrical component 8 is composed of a plug 801, a first waterproof line 802, a circuit breaker 803, a wire 804, a forward and reverse remote control switch 805, a second waterproof line 806, and a motor 17 connected in sequence. It is installed behind the housing 301 of the reducer 3. When driven manually, as described above, the two worms protrude a portion of the end surface of the cover of the reducer 3, so that they can be connected to the socket wrench 5, and the socket wrench 5 is used to manually drive the two worms to rotate.

[0072] The speed of the wing when flipping is calculated, the speed of the motor 17 is n=1000R / min, the number of teeth Z1 of the gear 345 is 17, the number of teeth Z2 of the large gear 331 is 85, and the number of teeth Z3 of the large worm gear 310 is 126. The calculated wing speed is approximately equal to 1.5R / min. When powered, the wing rotates 1.5 times per minute, which is ergonomic and easy to control the angle of the wing when flipping.

[0073] To calculate the up and down moving speed V of the reducer 3, first calculate the rotation speed of the drum 7, the number of teeth Z1 of the gear 345 = 17, the number of teeth Z4 of the pinion 336 = 60, and the number of teeth Z5 of the small worm gear 320 = 48. The diameter d of the drum 7 is 100 mm, and the circumference of the drum is about 314 mm. The up and down moving speed V of the reducer 3 is calculated to be about 15.7 mm / s. The reducer 3 moves 15.7 mm per second, which is ergonomic and easy to control the up and down moving distance of the reducer 3.

[0074] Based on the above 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.

[0075] (1) When there is power, flip the wing on the bracket. The specific steps are as follows:
