The permanent magnet wheel is concentrically installed on the load shaft and can rotate synchronously with the load shaft. The conductor wheel is concentrically installed on the motor shaft and can rotate synchronously with the motor shaft. During operation, the motor drives the conductor wheel to rotate synchronously, the magnetic fields of the conductor wheel and the permanent magnet wheel are coupled with each other, thereby driving the permanent magnet wheel to rotate, and the permanent magnet wheel drives the load to rotate. By adjusting the axial movement of the movable base, the motor moves axially with the movable base, and the coupled magnetic field between the conductor wheel and the permanent magnet wheel changes accordingly, thereby adjusting the rotational speed of the permanent magnet wheel.

[0004] When the above device is actually used, the height of the flange motor cannot be adjusted, and the flange motor and the fixed support seat are connected by bolts, which is rather cumbersome during disassembly and assembly. Content of the Utility Model

[0005] The utility model aims to overcome the disadvantages in the above-mentioned prior art that the height of the flange motor cannot be adjusted during actual use, and the flange motor and the fixed support seat are connected by bolts, which is rather cumbersome during disassembly and assembly.

[0006] A mobile base type magnetic wheel speed regulator for a flange motor is proposed, which includes a flange motor and a permanent magnet component. It also includes a fixed seat, a quick-release device, a support component, a mounting plate, a moving component and a moving seat. The flange motor is horizontally connected to the fixed seat. Through holes are provided at the four corners of the fixed seat, and a quick-release device is vertically arranged inside each through hole. The support component is arranged below the fixed seat, and the fixed seat is connected to the support component through the quick-release device. The mounting plate is located below the support component, and the support component is slidably arranged on the mounting plate. The moving component is arranged inside the support component and connected to the center of the support component, and the moving component is connected to the mounting plate. The permanent magnet component is located on one side of the fixed seat, and the moving seat is located on the other side of the permanent magnet component, and the permanent magnet component is respectively connected to the flange motor and the moving seat.

[0007] In the technical solution of the present utility model, when it is necessary to adjust the horizontal position of the flange motor, only need to start the servo motor, and the rotation direction of the output shaft of the servo motor is the same as the direction in which the flange motor needs to move. The gear will rotate synchronously with the flange motor. When the gear rotates, it can adjust the position of the support component and the fixed seat through the rack. When the fixed seat moves, it can drive the flange motor to move synchronously. When it is necessary to increase the height of the flange motor and the fixed seat, start the electric lead screw to make it rotate forward. On the contrary, when it is necessary to decrease the height of the flange motor and the fixed seat, start the electric lead screw to make it rotate in reverse. When installing the fixed seat, after inserting the fixed cylinder into the inside of the support plate, step on the fixed rod downward until the top end of the fixed rod is completely inserted into the inside of the fixed cylinder. At this time, the flange motor can be fixedly connected to the support plate through the fixed seat and the quick-release device, so as to solve the disadvantages that the height of the flange motor cannot be adjusted during actual use mentioned in the technical background, and the flange motor and the fixed support seat are connected by bolts, and the disassembly and assembly are relatively cumbersome.

[0008] Preferably, in the technical solution of the present utility model, the permanent magnet component includes a permanent magnet rotor and a conductor rotor. The conductor rotor is connected to the flange motor, and the permanent magnet rotor is connected to the moving seat. The permanent magnet rotor and the conductor rotor are magnetically connected. Therefore, when the conductor rotor rotates, it can drive the permanent magnet rotor to rotate. If the permanent magnet rotor stops rotating due to force majeure, the conductor rotor will not drive the permanent magnet rotor to rotate even if it rotates. Therefore, the permanent magnet rotor will not be damaged due to the rotation of the conductor rotor when it stops rotating.

[0009] Preferably, a load shaft is horizontally rotatably connected to the moving seat, and the permanent magnet rotor is connected to one end of the load shaft. When the permanent magnet rotor rotates, it can drive the load to rotate synchronously through the load shaft.

[0010] For the optimization of the technical solution of the present utility model, the quick-release device includes a nut, a fixing rod, a first spring, a stopper, a fixing cylinder, a bottom cylinder, a second spring, and an electromagnetic component. The fixing cylinder is located below the fixing seat and is arranged in the opening of the fixing seat. The nut is arranged above the fixing seat and is threadedly connected to the fixing cylinder. The fixing rod is vertically slidably arranged at the central position of the fixing cylinder. The first spring is vertically arranged below the fixing rod and sleeved on the fixing rod. There are two stoppers, which are respectively vertically arranged on both sides of the fixing rod. There are two groups of second springs, which are both arranged above the bottom cylinder, and the two groups of second springs are respectively arranged outside the two stoppers. The bottom cylinder is vertically arranged below the support plate of the support component and is connected to the support plate. There are two groups of electromagnetic components, which are both arranged inside the bottom cylinder and are respectively arranged on both sides of the fixing rod. When the flange motor is placed on the support plate and the fixing cylinder is inserted into the openings preset at the four corners of the support plate, the fixing rod can be stepped on downward. When the bottom end of the fixing rod is inserted into the inside of the bottom cylinder, the flange motor and the base can be fixed to each other.

[0011] For the optimization of the technical solution of the present utility model, the electromagnetic component includes a housing, a clamping block, a third spring, and an electromagnet. The housing is arranged inside the bottom cylinder and is connected to the inner wall of the bottom cylinder. The clamping block is slidably connected inside the housing. The third spring is located on one side of the clamping block. The electromagnet is vertically arranged inside the housing and is connected to the side plate of the housing, and the electromagnet is located on the other side of the third spring. When the electromagnet is energized, it will adsorb the slider into the inside of the housing. At this time, the fixing rod will pop out of the bottom cylinder under the action of the first spring, and the flange motor can be moved at this time.

[0012] For the optimization of the technical solution of the present utility model, the support component includes a box body, a support plate, an electric screw rod, a support rod, a fixing block, and a sliding block. The support plate is located above the box body, and openings are provided at the four corner positions of the support plate. A bottom cylinder is vertically arranged below each opening. There are four sliding blocks, which are divided into two groups. The two groups of sliding blocks are respectively arranged on both sides of the support plate. One end of each sliding rod is hinged to one end of the support rod. Two fixing blocks are arranged inside the two groups of sliding rods, and the two fixing blocks are respectively arranged at both ends of the sliding rod and are both fixed to the bottom plate of the box body. The other end of the support rod is hinged to the fixing block. The electric screw rod is connected below the support plate, and the two groups of sliding blocks are both threadedly connected to the electric screw rod. The moving component is located inside the box body and is connected to the bottom plate of the box body. When the electric screw rod rotates forward or backward, it will drive the sliding block to slide inside the chute of the support plate. When the sliding blocks slide relative to each other, they will drive the support plate to move up and down through the support rod, and then drive the flange motor to move up and down.

[0013] For the optimization of the technical solution of the present utility model, the moving component includes a servo motor, a gear, a rack and a slide rail. The servo motor is connected to the center position of the bottom plate of the box body. The gear is located on one side of the servo motor and is connected to the output shaft of the servo motor. The rack is connected to the mounting plate, and the gear passes through the bottom plate of the box body and meshes with the rack. There are two groups of slide rails, which are respectively arranged on both sides of the gear. Both groups of slide rails are connected to the bottom plate of the box body, and both groups of slide rails are slidably arranged on the mounting plate. When the servo motor drives the support component to move through the gear and the rack, the support component will synchronously drive the flange motor to move horizontally, so as to adjust the horizontal position of the flange motor.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] When the height of the flange motor needs to be adjusted in the present utility model, only need to rotate the electric screw rod forward or backward. When the electric screw rod rotates forward or backward, the relative distance between the two sliding blocks can be adjusted, and the height of the support plate will also move up and down following the relative distance between the two sliding blocks. And when installing the fixing seat on the support plate, only need to insert the fixing cylinder at the bottom of the fixing seat into the preset grooves at the four corners of the support plate, and then step on the fixing rod downward until the top end of the fixing rod is completely inserted into the inside of the fixing cylinder. At this time, the flange motor can be fixedly connected to the support plate through the fixing seat and the quick-release device, and the operation is simple and effective.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be described in detail in combination with the attached Figures 1-10 drawings in the embodiments of the present invention.

[0028] As Figures 1-2 shown, a moving base type magnetic wheel speed governor for a flange motor includes a flange motor 1 and a permanent magnet component 2, and also includes a fixed seat 3, a quick-release device 4, a support component 5, a mounting plate 6, a moving component 7 and a moving seat 8. The flange motor 1 is horizontally arranged on one side of the fixed seat 3 and is fixedly connected to the fixed seat 3 through a flange. The output shaft of the flange motor 1 passes through the fixed seat 3 and is connected to the conductor rotor 22 of the permanent magnet component 2. The permanent magnet component 2 is located on the other side of the fixed seat 3.

[0029] As Figures 1-2As shown, the permanent magnet assembly 2 includes a permanent magnet rotor 21 and a conductor rotor 22. The conductor rotor 22 is connected to the output shaft of the flange motor 1 by a pin key. Therefore, when the flange motor 1 rotates forward or backward, the conductor rotor 22 will be driven to rotate synchronously. The fixing seat 3 is vertically arranged above the support assembly 5, and through holes are provided at the four corners of the fixing seat 3. Quick-release devices 4 are arranged inside the through holes at the four corners of the fixing seat 3. The fixing seat 3 is connected to the support assembly 5 through the quick-release devices 4.

[0030] As Figures 1-2 shown, therefore, when needed, the support assembly 5 can drive the flange motor 1 and the conductor rotor 22 to move up and down through the fixing seat 3. The support assembly 5 is arranged below the fixing seat 3 and is slidably connected to the mounting plate 6. A moving assembly 7 is arranged inside the support assembly 5. The mounting plate 6 is arranged below the support assembly 5, and the moving assembly 7 passes through the support assembly 5 and is connected to the mounting plate 6. Therefore, when the flange motor 1 needs to be adjusted horizontally, the moving assembly 7 can drive the support assembly 5 to move horizontally on the mounting plate 6.

[0031] As Figures 1-2 shown, when the support assembly 5 moves horizontally, it can drive the flange motor 1 and the conductor rotor 22 to move horizontally. The moving seat 8 is on the other side of the permanent magnet assembly 2. A load shaft is horizontally rotatably arranged on the moving seat 8. The permanent magnet rotor 21 is fixed to the load shaft by a pin key, and the conductor rotor 22 is sleeved on the permanent magnet rotor 21. Therefore, when the flange motor 1 drives the conductor rotor 22 to rotate, the conductor rotor 22 will drive the permanent magnet rotor 21 to rotate synchronously. Since the permanent magnet rotor 21 is fixed to the load shaft, when the permanent magnet rotor 21 rotates, it will drive the load shaft to rotate synchronously.

[0032] As Figures 3-5 shown, the support assembly 5 includes a box body 51, a support plate 52, an electric screw rod 53, a support rod 54, a fixing block 55 and a sliding block 56. The support plate 52 is arranged above the box body 51 along the length direction of the box body 51. Through holes are provided at the four corners of the support plate 52, and a bottom cylinder 46 of the quick-release device 4 is vertically arranged below each through hole. The fixing cylinder 45 of the quick-release device 4 passes through the through hole and is connected to the bottom cylinder 46 below the through hole of the support plate 52. The bottom cylinder 46 is welded to the support plate 52. Therefore, when the support plate 52 moves up and down, it can drive the fixing seat 3 to move up and down through the fixing cylinder 45.

[0033] As Figures 3-5As shown in the figure, two chutes are opened below the support plate 52 along the length direction of the support plate 52. There are four sliding blocks 56, which are divided into two groups. The two groups of sliding blocks 56 are slidably arranged in the chutes below the support plate 52. One end of each support rod 54 is hinged to both ends of each sliding block 56. Two fixing blocks 55 are arranged inside each group of sliding blocks 56. The two fixing blocks 55 are both arranged at the central positions of the two sliding blocks 56, and the two fixing blocks 55 are respectively arranged at both ends of the sliding blocks 56.

[0034] As Figures 3-5 shown, the two fixing blocks 55 are both fixedly connected to the bottom plate of the box body 51 by bolts. The other ends of the support rods 54 at both ends of each group of sliding blocks 56 are hinged to the fixing blocks 55. The electric screw rod 53 is located below the support plate 52 and is fixedly connected to the support plate 52 by bolts. And the two groups of sliding blocks 56 are both threadedly connected to the electric screw rod 53. Therefore, when the electric screw rod 53 rotates forward, the two sliding rods in each group of sliding rods will approach each other. At this time, the support plate 52 will be lifted upward. On the contrary, when the electric screw rod 53 rotates reversely, the two sliding rods in each group of sliding rods will move away from each other. At this time, the support plate 52 will gradually fall.

[0035] As Figure 6 shown, the moving assembly 7 includes a servo motor 71, a gear 72, a rack 73 and a slide rail 74. The servo motor 71 is horizontally arranged inside the box body 51, and the servo motor 71 is fixedly connected to the central position of the bottom plate of the box body 51 by bolts. The gear 72 is located on one side of the servo motor 71, and the gear 72 is fixedly connected to the output shaft of the servo motor 71 by a pin key. Therefore, when the servo motor 71 rotates forward or reversely, the gear 72 will be driven to rotate synchronously. The gear 72 passes through the bottom plate of the box body 51 and meshes with the rack 73.

[0036] As Figure 6 shown, the rack 73 is arranged on the mounting plate 6 along the length direction of the mounting plate 6, and the rack 73 is fixedly connected to the mounting plate 6 by screws. There are two groups of slide rails 74, which are respectively arranged on both sides of the rack 73, and the slide rails 74 are fixedly connected to the bottom plate of the box body 51 by screws. The box body 51 is slidably arranged on the mounting plate 6 through the slide rails 74. Therefore, when the servo motor 71 drives the gear 72 to rotate forward or reversely, the gear 72 will mesh with the rack 73 and drive the box body 51 and the fixed seat 3 to slide horizontally through the slide rails 74. When the fixed seat 3 slides horizontally, the flange motor 1 can be driven to slide horizontally.

[0037] As Figures 7-9As shown in the figure, the quick-release device 4 includes a nut 41, a fixed rod 42, a first spring 43, a stop block 44, a fixed cylinder 45, a bottom cylinder 46, a second spring 47, and an electromagnetic assembly 9. Through holes are provided at the four corner positions of the fixed seat 3, and a fixed cylinder 45 is vertically arranged below each through hole. The top end of the fixed cylinder 45 passes through the through hole of the fixed seat 3 and is arranged above the fixed seat 3. The nut 41 is arranged above the fixed seat 3 and is threadedly connected to the fixed cylinder 45. After the nut 41 is connected to the fixed cylinder 45, the fixed cylinder 45 can be fixedly connected to the fixed seat 3.

[0038] As Figures 7-9 shown, the bottom end of the fixed cylinder 45 passes through the support plate 52 and is connected to the bottom cylinder arranged at the bottom end of the support plate 52. The fixed rod 42 is vertically slidably arranged at the central position of the fixed cylinder 45. A groove is provided at the central position of the top end of the fixed cylinder 45. The first spring 43 is located below the fixed rod 42 and is vertically arranged in the groove, and the first spring 43 is sleeved on the fixed rod 42. A chute is provided on the bottom cylinder 46, and two stop blocks 44 are both slidably arranged in the chute above the bottom cylinder 46, and the two stop blocks 44 are respectively arranged on both sides of the fixed rod 42.

[0039] As Figures 7-9 shown, therefore when the fixed rod 42 moves downward, it will push the two stop blocks 44 to slide synchronously towards both sides of the bottom cylinder 46. After the stop blocks 44 slide towards both sides, they can block the fixed cylinder 45 through their own shapes to prevent it from moving. So at this time, the fixed cylinder 45 cannot be separated from the bottom cylinder 46, and when the fixed rod 42 moves downward, it will compress the first spring 43, and the first spring 43 will deform and start to store energy at this time. There are two second springs 47, both of which are arranged in the chute at the top end of the bottom cylinder 46, and the two second springs 47 are respectively arranged on both sides of the two stop blocks 44.

[0040] As Figures 7-9 shown, therefore when the stop blocks 44 are squeezed by the fixed rod 42 and slide towards both sides, the second springs 47 will be squeezed and deformed and start to store energy. So when the fixed rod 42 moves upward to its original position, the two second springs 47 will also synchronously eject the two stop blocks 44 towards the axial position of the bottom cylinder 46 to make the two stop blocks 44 return to their original positions. After the two stop blocks 44 return to their original positions, the fixed cylinder 45 can be separated from the bottom cylinder 46. There are two groups of electromagnetic assemblies 9, both of which are arranged inside the bottom cylinder 46 and are respectively arranged on both sides of the fixed rod 42.

[0041] As Figure 10As shown, the electromagnetic assembly 9 includes a housing 91, a clamping block 92, a third spring 93, and an electromagnet 94. The housing 91 is vertically arranged inside the bottom cylinder 46 and connected to the top plate of the bottom cylinder 46. The clamping block 92 is slidably connected inside the housing 91. The third spring 93 is located on one side of the clamping block 92. The electromagnet 94 is vertically arranged inside the housing 91 and connected to the side plate of the housing 91, and the electromagnet 94 is located on the other side of the third spring 93. When the fixed rod 42 moves downward, the third spring 93 will eject the clamping block 92 towards the fixed rod 42 until the clamping block 92 is stuck into the groove at the bottom of the fixed rod 42.

[0042] As Figure 10 shown, at this time, the fixed rod 42 cannot be reset upward. When it is necessary to take out the fixed cylinder 45 from the support plate 52, just activate the electromagnet 94. After the electromagnet 94 is powered on, it will start to adsorb the slider, so that the slider slides towards the electromagnet 94. At this time, the front end of the slider can be taken out from the slot at the bottom of the fixed rod 42. Subsequently, the fixed rod 42 can bounce back to its original position under the action of the first spring 43. At this time, the fixed cylinder 45 can be taken out from the support plate 52.

[0043] The movement process of this embodiment: After fixing the mounting plate 6 to the ground with bolts, the fixed cylinder 45 can be connected to the fixed seat 3 through the nut 41. Subsequently, after aligning the four fixed cylinders 45 with the through holes at the four corners of the support plate 52, the fixed cylinder 45 can be inserted into the inside of the support plate 52 through the opening. After the bottom ends of the fixed cylinders 45 are all inserted into the inside of the support plate 52, activate the electromagnet 94. After the electromagnet 94 adsorbs the clamping block 92 into the inside of the housing 91, move the fixed rod 42 downward until the top end of the fixed rod 42 is completely inserted into the inside of the fixed cylinder 45.

[0044] If it is necessary to increase the height of the flange motor 1, start the electric lead screw 53 to make it rotate forward. On the contrary, if it is necessary to decrease the height of the flange motor 1, start the electric lead screw 53 to make it rotate backward. If it is necessary to horizontally adjust the position of the flange motor 1, start the servo motor 71 to drive the gear 72 to rotate forward or backward.

[0045] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited by this. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
