Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a low-speed, high-torque permanent magnet direct-drive motor that is easy to fix. Background Art

[0002] In recent years, direct drive systems have been adopted in products of international ropeway companies. Ropeways using direct drive technology have eliminated bulky reducers and directly connected low-speed, high-torque direct drive motors to the drive wheels. Compared with traditional motor and reducer drives, direct drive omits a series of disadvantages brought by the reducer and thus has many advantages. At present, direct drive ropeways have been built and put into use in China.

[0003] For example, a Chinese patent with announcement number CN216252325U discloses a motor fixing structure, including a frame, a snap base and a snap cover arranged on one side of the frame, wherein a through hole is provided in the middle area of ​​the snap base, and a motor shaft hole is provided in the center of the snap cover; the snap base is circumferentially provided with at least one fixed tooth opening and at least one guide fixing groove; the snap cover is provided with at least one elastic tooth opening corresponding to at least one fixed tooth opening, and at least one guide stop opening corresponding to at least one guide fixing groove, and the at least one elastic tooth opening is correspondingly engaged with at least one fixed tooth opening by rotating the snap cover, and at least one guide stop opening is correspondingly entered into at least one guide fixing groove.

[0004] However, the above scheme has the following shortcomings: in the above patent, the motor and the frame can be fixed together by rotating the snap cover clockwise, but in the installation process of the cableway motor, since low-speed and high-torque permanent magnet direct-drive motors are now used, the weight of the commonly used low-speed and high-torque permanent magnet direct-drive motors is generally much greater than that of conventional ordinary direct-drive motors, so the installers need to use a crane to lift the low-speed and high-torque permanent magnet direct-drive motor to the cableway motor installation location before installation. However, since most cableways are located in mountains and forests, when the trees in the installation area are dense, the crane cannot lift the motor due to the obstruction of the trees. At this time, the staff needs to lift the low-speed and high-torque permanent magnet direct-drive motor by manpower for installation, which is time-consuming and labor-intensive, and is not convenient for quick fixation of the low-speed and high-torque permanent magnet direct-drive motor. For this reason, we have introduced a low-speed and high-torque permanent magnet direct-drive motor that is easy to fix. Summary of the invention

A plurality of groups of inclined teeth 30 are provided on the middle part of the outside of the T-shaped ring 11. The positioning ring 5 rotates to drive the T-shaped ring 11 connected to its lower end to start rotating. During the rotation process, the T-shaped ring 11 drives the bevel gear 20 to start rotating through the inclined teeth 30. The rotation of the bevel gear 20 drives the take-up wheel 4 to start rotating. The four groups of take-up wheels 4 rotate synchronously to start winding the corresponding wire ropes 7. At this time, the low-speed and high-torque motor body 1 starts to move upward;

[0027] Bevel gears 20 are arranged all around the outer side of the T-shaped ring 11, and several groups of inclined teeth 30 are meshed with the bevel gear 20. The bevel gear 20 is movably connected to the T-shaped ring 11. When the T-shaped ring 11 moves downward, it will drive the bevel gear 20 to move downward synchronously.

When the positioning ring 5 drops to the final position, the four groups of screws 10 are screwed into the corresponding nut 13. At this time, the low-speed and high-torque motor body 1 is fixed.

[0028] Embodiment 2:

[0029] On the basis of Example 1, in order to ensure that the motor shaft 6 will not drive the positioning ring 5 to rotate during the rotation of the low-speed and high-torque motor body 1 after it is installed, and at the same time ensure that the positioning ring 5 can move to the highest point under normal conditions, the positioning ring 5 is movably connected with four groups of limit blocks 24 on the side close to the motor shaft 6, and the limit blocks 24 are slidably connected in the limit grooves 23, and the limit grooves 23 are arranged in the motor shaft 6.

The adjusting screw 33 is rotated to disengage the limit blocks 24 from the limit grooves 23 and enter the receiving grooves 32. At this time, the motor shaft 6 will not drive the positioning ring 5 to rotate when it rotates;

[0030] The side of the take-up wheel 4 away from the bevel gear 20 is movably connected to the slider 27, the slider 27 is slidably connected to the slide groove 28, the slide groove 28 is opened in the connecting groove 3, the upper and lower ends of the nut 13 are fixedly connected with the guide ring 25, the guide ring 25 is slidably connected to the guide groove 26, the guide groove 26 is opened in the connecting ring 2, the nut 13 drives the guide ring 25 connected to the upper and lower ends to start rotating during the rotation process, and the guide ring 25 moves along the guide groove 26 to limit the nut 13, the upper and lower sides of the nut 13 are provided with screw mounting holes 17, and the screw mounting holes 17 are opened in the connecting ring 2;

[0031] A T-shaped guide tube 15 is provided on the upper side of the screw mounting hole 17, and the lower end of the T-shaped guide tube 15 is slidably connected to the annular groove 18, and the annular groove 18 is provided in the connecting ring 2. Two groups of first springs 14 are fixedly connected in the annular groove 18, and the other end of the first spring 14 is fixedly connected to the T-shaped guide tube 15. A T-shaped limiting groove 16 is provided in the lower end of the positioning ring 5, and an I-shaped rod 22 is slidably connected in the T-shaped limiting groove 16.

A screw 10 is movably connected in the upper end of the clamping ring 9, and hooks 8 are fixedly connected to the lower end of the clamping ring 9. The upper end of the wire rope 7 and the hook 8 are clamped together.

[0032] Working principle: when in use, the clamping ring 9 is clamped to the upper end of the motor mounting hole opened in the cableway motor mounting frame 29. After the installation is completed, the four sets of steel wire ropes 7 located in the upper end of the low-speed and high-torque motor body 1 are clamped to the corresponding hooks 8. After the clamping is completed, the low-speed and high-torque motor body 1 is connected to an external power supply to make its motor shaft 6 start to rotate. The rotation of the motor shaft 6 drives the positioning ring 5 to start to rotate. The rotation of the positioning ring 5 drives the T-shaped ring 11 connected to its lower end to start to rotate. During the rotation process, the T-shaped ring 11 drives the cone through the inclined teeth 30 The gear 20 starts to rotate, and the rotation of the bevel gear 20 drives the take-up wheel 4 to start rotating. The four groups of take-up wheels 4 rotate synchronously to start winding the corresponding wire ropes 7. At this time, the low-speed and high-torque motor body 1 starts to move upward. During the upward movement of the low-speed and high-torque motor body 1, the T-shaped guide tube 15 can guide the screw 10, so that the lower end of the screw 10 enters the screw mounting hole 17 for storage. When the upper end of the positioning ring 5 contacts the lower end of the cableway motor mounting frame 29, the low-speed and high-torque motor body 1 continues to move upward.

[0033] The positioning ring 5 is squeezed to move inward and drives the T-ring 11 to move synchronously. When the T-ring 11 moves downward, the bevel gear 20 moves downward synchronously, so that the low-speed and high-torque motor body 1 can always move upward. The teeth on the side of the T-ring 11 mesh with several groups of connecting teeth 12 when moving downward. At this time, the nut 13 starts to rotate. The nut 13 screws the screw 10 into the nut 13 during the rotation. When the positioning ring 5 drops to the final position, the four groups of screws 10 are screwed into the relative nuts 13. At this time, the low-speed and high-torque motor body 1 is fixed. The adjusting screw 33 is rotated to make the limit block 24 disengage from the limit groove 23 and enter the storage groove 32. At this time, the motor shaft 6 will not drive the positioning ring 5 to rotate when it rotates.
