In the prior art, the cylindrical stator barrel needs to be tied to the gantry truck by ropes for lifting. After the stator barrel is moved to a designated location, the ropes need to be disassembled to separate the cylindrical stator barrel from the gantry truck, thereby increasing the difficulty of lifting the cylindrical stator barrel.

A support plate 6 is coaxially fixed to the end of the boom 1 away from the limit ring 2. The bottom of the support plate 6 abuts the ground to form a support, so that the boom 1 is not easy to swing, thereby improving the stability of the placement of the boom 1; the guide ring 1 31 is coaxially fixed to the end of the boom 1 close to the support plate 6. The number of articulated arms 1 34 can be two, three or more. In the embodiment of the present application, the number of articulated arms 1 34 is three. One ends of the three articulated arms 1 34 are rotatably connected to the outer peripheral surface of the guide ring 1 31 at uniform intervals. The other ends of the three articulated arms 1 34 correspond to and are rotatably connected to the clamping blocks 4 one by one. The clamping blocks 4 are provided with a rotating cavity 41 for rotating the end of the articulated arms 1 34 toward the end face of the boom 1.

In the embodiment of the present application, the number of articulated arms 36 is three, and one end of the three articulated arms 36 is evenly spaced and rotatably connected to the outer circumference of the guide ring 3 33, and the other ends of the three articulated arms 36 correspond one-to-one with the tightening blocks 4 and are rotatably connected to the inner wall of the rotating chamber 41, and the articulated arms 3 36 and the articulated arms 1 34 are located at both ends of the tightening block 4, and the articulated arms 2 35 are close to the articulated arms 1 34.

[0036] Reference Figure 1When the stator cylinder needs to be moved in the production workshop, the gantry driving end passes through the inner ring of the limit ring 2, and the inner ring wall of the limit ring 2 abuts against the surface of the gantry driving end to form a limit, thereby fixing the boom 1 on the gantry driving end. At the same time, the gantry driving end drives the boom 1 to lift, and the guide ring 1 31 approaches the guide ring 2 32 along the axis of the boom 1, driving the end of the articulated arm 1 34 and the end of the articulated arm 2 35 close to the boom 1 to rotate in the direction away from each other, driving the end of the articulated arm 1 34 and the end of the articulated arm 2 35 located on the clamping block 4 to rotate in the direction close to each other, driving the clamping block 4 away from the boom 1, and the surface of the clamping block 4 away from the rotating cavity 41 abuts against the inner wall of the stator cylinder to form a limit. At the same time, the articulated arm 3 36 rotates in the direction close to the articulated arm 2 35, and the articulated arm 3 36 and the articulated arm 1 34 are located at both ends of the clamping block 4, and the end of the articulated arm 3 36 provides support for the clamping block 4 to abut against the inner wall of the stator cylinder, thereby ensuring that the surface of the clamping block 4 is The stability of the stator barrel inner cavity wall is tightened. When the gantry crane lifts the stator barrel through the motor stator lifting equipment, the gravity of the stator barrel itself is equal to the static friction force between the tightening block 4 and the inner cavity wall of the stator barrel, making it difficult for the stator barrel to separate from the tightening block 4, thereby realizing the stable transportation of the stator barrel by the gantry crane. When the stator barrel moves to the specified position, the support plate 6 abuts against the ground, driving the guide ring 33 to slide along the axis of the suspension rod 1 in the direction away from the guide ring 1 31, driving the end of the articulated arm 1 34 and the end of the articulated arm 36 close to the suspension rod 1 to rotate in the direction away from each other, driving the end of the articulated arm 1 34 and the end of the articulated arm 36 located on the tightening block 4 to rotate in the direction close to each other, driving the tightening block 4 to approach the suspension rod 1, so that the tightening effect between the surface of the tightening block 4 and the inner cavity wall of the stator barrel disappears, realizing the rapid separation of the stator barrel and the tightening block 4, without the user using ropes to tie and fix the stator barrel to the driving end of the gantry crane, thereby reducing the difficulty of lifting the stator barrel.

[0037] Reference Figure 1 A support ring 7 is coaxially fixed to the end of the guide ring three 33 away from the guide ring two 32. The support ring 7 is for the staff to hold and drive the guide ring three 33 to slide along the axis of the suspension rod 1. The support ring 7 provides a force point for the staff, thereby improving the convenience of using the motor stator lifting equipment.

[0038] The implementation principle of a motor stator hoisting device in Example 1 of the present application is as follows: when the stator barrel needs to be transported in a production workshop, the gantry driving end passes through the inner ring of the limiting ring 2, and the inner ring wall of the limiting ring 2 abuts against the surface of the gantry driving end to form a limit, thereby fixing the boom 1 on the gantry driving end. At the same time, the gantry driving end drives the boom 1 to be lifted, and the guide ring 1 31 approaches the guide ring 2 32 along the axis of the boom 1, driving the end of the articulated arm 1 34 and the end of the articulated arm 2 35 close to the boom 1 to move toward each other. The two arms 36 and 37 rotate in a direction away from each other, driving the ends of the articulated arm 1 34 and the ends of the articulated arm 2 35 on the pressing block 4 to rotate in a direction close to each other, driving the pressing block 4 away from the suspension rod 1, and the surface of the pressing block 4 facing away from the rotating cavity 41 presses against the inner wall of the stator tube to form a limit, and at the same time, the articulated arm 3 36 rotates in a direction close to the articulated arm 2 35, and the articulated arm 3 36 and the articulated arm 1 34 are located at both ends of the pressing block 4, and the ends of the articulated arm 3 36 provide support for the pressing block 4 to press against the inner wall of the stator tube , thereby ensuring the stability of the contact between the surface of the clamping block 4 and the inner wall of the stator barrel. When the gantry lifts the stator barrel through the motor stator hoisting equipment, the gravity of the stator barrel itself is equal to the static friction between the clamping block 4 and the inner wall of the stator barrel, making it difficult for the stator barrel to separate from the clamping block 4, thereby realizing the stable transportation of the stator barrel by the gantry. When the stator barrel moves to the specified position, the support plate 6 contacts the ground, driving the guide ring 3 33 to slide along the axis of the suspension rod 1 in the direction away from the guide ring 1 31, driving the stator barrel near the suspension rod 1 to move. The end of the articulated arm 1 34 and the end of the articulated arm 36 of the rod 1 rotate in the direction away from each other, driving the end of the articulated arm 1 34 and the end of the articulated arm 36 located on the clamping block 4 to rotate in the direction close to each other, driving the clamping block 4 to approach the suspension rod 1, so that the clamping effect between the surface of the clamping block 4 and the inner wall of the stator tube disappears, and the stator tube and the clamping block 4 are quickly separated, without the user having to tie and fix the stator tube to the driving end of the gantry car with ropes, thereby reducing the difficulty of hoisting the stator tube.

The material of the tightening airbag 8 can be rubber or silicone. In the embodiment of the present application, the material of the tightening airbag 8 is rubber, which has a certain deformation ability. The tightening airbag 8 is located on the side of the rotation axis of the second articulated arm 35 close to the third articulated arm 36. When the second articulated arm 35 and the first articulated arm 34 located on the tightening block 4 rotate in the direction away from each other, the tightening block 4 is driven to approach the suspension rod 1, reducing the storage space of the motor stator hoisting equipment, thereby realizing the storage of the motor stator hoisting equipment. At the same time, the tightening airbag 8 is embedded in the rotating cavity 41, and the surface of the tightening airbag 8 is pressed against the inner wall of the rotating cavity 41 to form a limit, so that the second articulated arm 35 is not easy to rotate in the rotating cavity 41, thereby ensuring the stability of the storage of the motor stator hoisting equipment.

The inflatable component 9 includes an inflatable piston 91, an elastic member 92, a driving rod 93, a limit block 94, a gear 95 and a rack 96. The material of the inflatable piston 91 can be rubber or silicone. In the embodiment of the present application, the material of the inflatable piston 91 is rubber, which has a certain deformation ability. An inflatable flow channel 42 for the inflatable piston 91 to slide is opened on the inner wall of the rotating cavity 41 toward the second articulated arm 35. An inflatable flow channel 351 for the end of the inflatable piston 91 to be embedded is opened on the surface of the second articulated arm 35. The inflatable flow channel 351 is connected to the inner cavity of the clamping airbag 8; the elastic member 92 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 92 is a compression spring with It has a certain deformation ability. One end of the elastic member 92 in the elastic direction is fixed to the inner wall of the inflation channel 1 42, and the other end of the elastic member 92 in the elastic direction is fixed to the surface of the inflation piston 91. When the surface of the airbag 8 is pressed against the inner wall of the rotating chamber 41, the inflation channel 1 42 is connected to the inflation channel 2 351, and the elastic force of the elastic member 92 drives the inflation piston 91 to slide in the direction close to the inflation channel 2 351. The end of the inflation piston 91 is embedded in the inflation channel 2 351, and the outer peripheral surface of the inflation piston 91 is pressed against the inner wall of the inflation channel 2 351 to form a seal, pushing the air in the inflation channel 2 351 into the inner cavity of the airbag 8, pressing against the surface of the airbag 8 to increase pressure and expand, and pressing against the inner wall of the rotating chamber 41 to form a limit, further improving the limit stability of the articulated arm 2 35 in the rotating chamber 41.

When the limit block 94 moves toward the driving cavity 43, the guide surface 941 is in the shape of a circular arc convex. When the direction rotates, the guide surface 941 abuts against the inner wall of the driving chamber 43 and guides the limit block 94 to be embedded in the driving chamber 43. The guide surface 941 abuts against the inner wall of the driving chamber 43 to form a limit, thereby reducing the wear between the limit block 94 and the clamping block 4, and at the same time drives the inflation piston 91 to slide in the direction away from the inflation flow channel 2 351. The end of the inflation piston 91 is separated from the inflation flow channel 2 351, so that the limiting effect of the inflation piston 91 on the articulated arm 2 35 disappears, thereby realizing the directional sliding of the inflation piston 91.

[0042] Reference Figure 2 and Figure 3The gear 95 is coaxially fixed on the rotating shaft of the articulated arm 2 35 located in the rotating chamber 41. The inner wall of the rotating chamber 41 is provided with a sliding chamber 44 for the rack 96 to slide. The sliding direction of the rack 96 and the sliding direction of the inflatable piston 91 are perpendicular to each other. The gear 95 meshes with the rack 96. The sliding chamber 44 is connected to the inflatable flow channel 1 42. When the end of the articulated arm 1 34 and the end of the articulated arm 2 35 located on the abutting block 4 rotate in a direction away from each other, the gear 95 rotates to drive the rack 96 to slide in a direction close to the inflatable flow channel 1 42. The surface of the rack 96 abuts against the inner wall of the sliding chamber 44 and closes the inflatable flow channel 1 42. The surface of the inflatable piston 91 abuts against the surface of the rack 96 and limits the inflatable piston 91 in the inflatable flow channel 1 42, so that the inflatable piston 91 It is not easy to separate from the inflation channel 42, thereby improving the limiting stability of the inflation piston 91 in the inflation channel 42; when the end of the articulated arm 2 35 and the end of the articulated arm 1 34 located on the abutting block 4 rotate in the direction approaching each other, the rotation of the gear 95 drives the rack 96 to slide in the direction away from the inflation channel 42, and the sealing effect of the rack 96 on the inflation channel 42 disappears, the inflation channel 1 42 is connected to the inflation channel 2 351, and the elastic force of the elastic member 92 drives the inflation piston 91 to embed into the inflation channel 2 351 along the inner wall of the inflation channel 1 42, and the outer peripheral surface of the inflation piston 91 presses against the inner wall of the inflation channel 2 351, so that the articulated arm 2 35 is not easy to deflect in the rotating chamber 41, thereby improving the stability of the motor stator hoisting equipment storage.

[0043] The implementation principle of a motor stator lifting device in Example 2 of the present application is as follows: when the end of the articulated arm 2 35 and the end of the articulated arm 1 34 located on the clamping block 4 rotate in a direction approaching each other, the rotation of the gear 95 drives the rack 96 to slide in a direction away from the inflation channel 1 42, and the sealing effect of the rack 96 on the inflation channel 1 42 disappears. The inflation channel 1 42 is connected to the inflation channel 2 351, and the elastic force of the elastic member 92 drives the inflation piston 91 to embed into the inflation channel 2 351 along the inner wall of the inflation channel 1 42. The outer peripheral surface of the inflation piston 91 presses against the inner wall of the inflation channel 2 351, so that the articulated arm 2 35 is not easy to deflect in the rotating chamber 41, thereby improving the stability of the storage of the motor stator lifting device.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
