[0035] Specifically, the accommodating member 101 includes a bearing box 101a, a connecting plate 101b, a movable groove 101c, an inner plate 101d and a groove to be embedded 101e. The bearing box 101a can make the rotor inside it and a bearing box 101a is provided at both ends of the rotor. The connecting plate 101b is arranged on the bearing box 101a, and the connecting plate 101b is fixedly connected to the bearing box 101a. The connecting plate 101b is arranged between the two bearing boxes 101a. The movable groove 101c is arranged on the connecting plate 101b. The movable groove 101c is arranged on the connecting plate 101b. Two movable grooves 101c are arranged on one connecting plate 101b. The two movable grooves 101c are stacked so that a groove of a certain width is left in the middle position of the connecting plate 101b. The inner plate 101d is arranged in the movable groove 101c. The inner plate 101d moves It is connected to the movable groove 101c, and the inner plate 101d is a structure after the "convex" character is rotated 180 degrees, and a part of the wider part on the upper side is cut off so that a semicircular arc shape is left on the top of the inner plate 101d, and the narrower part is in the movable groove 101c, so that the entire inner plate 101d can move in the movable groove 101c, wherein the semicircular arc shape on the top of the inner plate 101d can be used to contact the rotor to facilitate further lifting of the rotor to assist in the tile turning work, and the groove 101e to be embedded is set on the inner plate 101d, and the groove 101e to be embedded is opened on the inner plate 101d.

The storage slot 102a is opened on the bearing box 101a, so that a slot with the same structure as the embedded plate 101d is opened on one side of the bearing box 101a, so that the embedded plate 101d is moved into the storage slot 102a, so that the embedded plate 101d is moved out of the bearing box 101a when it is used. In this way, the inner plate 101d can be used to lift the rotor to facilitate the tile turning operation. The inner block 102b is fixedly connected to the bearing box 101a and is located at the bottom of the storage slot 102a. It is used to move the inner plate 101d to the storage slot 102a and cooperate with the inner block 102b to better position the inner plate 101d in the storage slot 102a. Since the inner block 102b is rectangular, other objects can be embedded and positioned on the inner block 102b, which will not affect the operation of the equipment in the bearing box 101a. The drop groove 102c is arranged on the storage groove 102a. The drop groove 102c is opened on the storage groove 102a. The drop groove 102c is connected to the storage groove 102a.

[0037] Furthermore, the moving member 103 includes an adjustment groove 103a, a transverse movement groove 103b, a moving rod 103c, a lifting column 103d, an adaptation groove 103e, and a lifting plate 103f. The adjustment groove 103a and the transverse movement groove 103b are provided on the connecting plate 101b. The adjustment groove 103a is opened on both sides of the connecting plate 101b, runs through the entire connecting plate 101b, and is located on both sides of the movement groove 101c. The adjustment groove 103a has a certain length and width, facilitating the adjustment of objects thereon within a certain range. The transverse movement groove 103b is opened on the connecting plate 101b and is perpendicular to the opening direction of the adjustment groove 103a on both sides of the adjustment groove 103a. The transverse movement groove 103b can control the longitudinal movement range of the objects provided thereon on the connecting plate 101b. The moving rod 103c is provided on the transverse movement groove 103b, and the moving rod 103c is movably connected to the transverse movement groove 103b.

Moreover, the lifting column 103d can move along with the longitudinal movement of the moving rod 103c. The lifting column 103d can move upward to disengage from the moving rod 103c, and the lifting column 103d is a structure after rotating a "T" shape clockwise by 90 degrees. The "|" part thereof can be embedded into the embedding groove 101e of the embedded plate 101d, so that the lifting column 103d and the embedded plate 101d can be connected.

The adaptation groove 103e is opened on the lifting column 103d and is provided in the "-" part, and is adapted to the moving column at the bottom side. The adaptation groove 103e is one that allows the moving column to enter. Conversely, moving the lifting column 103d upward can disengage it from the moving column. When not moving upward, the lifting column 103d can move horizontally arbitrarily on the moving column and can also move along with the movement of the moving column. There are two lifting columns 103d on one moving rod 103c, located on both sides of the embedded plate 101d. Thus, due to the connection relationship of the lifting columns 103d, the embedded plate 101d can be adjusted in the front, back, left, and right directions, and the embedded plate 101d can be moved to a position suitable for lifting the rotor. The lifting plate 103f is fixed on the lifting column 103d. The lifting plate 103f is a semi-circular arc structure, which is a reserved connection structure for facilitating the lifting operation of the lifting column 103d.

[0038] During the operation, during the process of lifting the rotor during the tile turning work, first, the lifting column 103d is connected to the moving column under the action of the adaptation groove 103e. As the moving column moves in the transverse movement groove 103b, the lifting column 103d is pushed, so that a part of the lifting column 103d is embedded into the embedding groove 101e of the embedded plate 101d, realizing the connection between the embedded plate 101d and the lifting column 103d.

[0039] With the connection between the lifting column 103d and the inner plate 101d, the inner plate 101d can be moved out of the storage slot 102a, and under the action of the falling block 102d and the falling slot 102c, the inner plate 101d gradually moves into the moving slot 101c. Since there is an inner plate 101d in a moving slot 101c, the inner plate 101d can move in the moving slot 101c to the position that is most conducive to lifting the rotor, so the lifting operation of the rotor can be realized more stably, and accurate lifting of any position of the rotor can be achieved, ensuring uniform force and stability of the entire rotor during the lifting process.

[0045] The remaining structures are the same as those of Example 1.

[0046] Operation process: by setting the inclined groove 201c, the moving shaft 202a on the inclined groove 201c and the pushing column 202b on the moving shaft 202a in the operation groove 201a on the inner panel 101d, the pushing column 202b is pushed by the lifting column 103d when entering the slot to be inserted 101e, so that the pushing column 202b moves a certain distance and height with the first spring 203a and the arc plate 203b on the first spring 203a, so that the arc plate 203b moves out of the inner panel 101d, As the lifting plate 103f on the lifting column 103d is connected and lifted, the arc plate 203b on the embedded plate 101d contacts the rotor and lifts it accordingly.

The width of the connecting frame 301c is larger than the lifting column 103d, so the bottom of the connecting frame 301c is reserved to allow the lifting column 103d to contact, and the lifting column 103d is extended on both sides, and the extended part carries There are grooves for matching bolts 301b and connecting holes 301a, so that the lifting column 103d and the connecting frame 301c can be connected together by using bolts 301b. When the connecting frame 301c is lifted, the lifting column 103d can move accordingly. The connecting frame 301c is a structure after the "concave" character is rotated 180 degrees, and the concave side has the same curvature as the semi-circular arc surface of the inner plate 101d. In this way, when the connecting frame 301c and the inner plate 101d are connected together, a circular hole with a certain diameter is formed in the middle. The circular hole is convenient for wrapping and lifting the rotor and improving the stability of the lifting operation. The lifting hole 301d is arranged on the connecting frame 301c. The lifting hole 301d is opened on the connecting frame 301c and is located on both sides of the connecting frame 301c. In this way, the lifting hole 301d is the same as the lifting plate 103f, and is a structure for lifting and clamping the rotor.

[0050] Furthermore, the rotating member 302 includes a rotating groove 302a, a support shaft 302b and a rotating block 302c. The rotating groove 302a is arranged on the connecting frame 301c. The rotating groove 302a is opened on the connecting frame 301c and is arranged on both sides of the connecting frame 301c, so that other objects can be set on the rotating groove 302a for operation. The support shaft 302b is arranged on the rotating groove 302a. The support shaft 302b is fixedly connected to the rotating groove 302a and is arranged at the top position of the rotating groove 302a, so that more moving space is provided for the object on the support shaft 302b. The rotating block 302c is arranged on the support shaft 302b, and the rotating block 302c is rotatably connected to the support shaft 302b. The rotating block 302c has a certain length, and one side of the rotating block 302c is connected to the support shaft 302b, so that the rotating block 302c can be subjected to force to deflect at a certain angle under the action of the support shaft 302b.

[0051] Furthermore, the fixing member 303 includes a rotation groove 303a, a rotation rod 303b, a pushing surface 303c, an outer surface 303d, a hidden surface 303e and a positioning surface 303f. The rotation groove 303a is arranged on the connection frame 301c. The rotation groove 303a is opened on the connection frame 301c and is located on both sides of the connection frame 301c. The rotation groove 303a is a groove with a thread. The rotation grooves 303a are symmetrically arranged on both sides of a connection frame 301c. The rotation rod 303b is arranged on the rotation groove 303a. The rotation rod 303 b is rotatably connected to the rotating groove 303a, and the rotating rod 303b has a thread adapted to the rotating groove 303a, so that when the rotating rod 303b is rotated, it can enter the rotating groove 303a, and also enter the connecting frame 301c, so that the rotating rod 303b can gradually push the rotating block 302c when rotating, so that the pushing block gradually moves toward the inner plate 101d, so that the movement of the inner plate 101d can be fixed, so that when the rotor is lifted, the first lifting component 200 can be more firmly wrapped and enhanced;

[0052] Among them, the pushing surface 303c and the external surface 303d, the hidden surface 303e and the positioning surface 303f are arranged on the rotating block 302c, the pushing surface 303c is arranged on the rotating block 302c towards the rotating rod 303b, the pushing surface 303c is a convex surface of the rotating block 302c, which can make the rotating rod 303b move and push the contact surface, the external surface 303d is arranged on the opposite side of the pushing surface 303c, and the external surface 303d is biased towards the middle position of the connecting frame 301c, when the rotating rod 303b will not be pushed into the rotating groove 303a, the external surface 303d is in the rotating groove 302a, so that the rotating block 302c is in the rotating groove 302a, and does not affect the work of other devices, the hidden surface 303e is connected to the external surface 303d, and its hidden surface 303e has a certain curvature, This curvature is the same as the curvature of the semicircular arc surface on the connecting frame 301c, but when the rotating block 302c is in the rotating groove 302a, the hidden surface 303e is just set between the embedded plate 101d and the connecting frame 301c, and is adapted to the curvature of the two. The positioning surface 303f is connected to the hidden surface 303e and is located at the bottom side of the rotating block 302c. Its positioning surface 303f is adapted to the outer side surface of the arc plate 203b, so that when the rotating rod 303b pushes the rotating block 302c, the positioning surface 303f of the rotating block 302c can be in contact with the arc plate 203b, and when the arc plate 203b contacts the rotor, the arc plate 203b will not be displaced, which is used to fix the position of the arc plate 203b, so that it can better play a positioning role when the rotor is wrapped and lifted, thereby reinforcing the stability of the lifting.

[0053] The remaining structure is the same as that of Example 2.

[0054] Operation steps: through the setting of the first lifting component 200, the bolt 301b is used to connect the connection frame 301c and the lifting column 103d, and then the rotating rod 303b is rotated to make the rotating rod 303b enter the rotating groove 303a and move. When the rotating rod 303b moves, it will push the rotating block 302c, so that the part of the rotating block 302c with the positioning surface 303f moves and contacts the position of the arc plate 203b, so that the arc plate 203b is positioned, so that the wrapping clamping effect when lifting the rotor can be achieved, which can assist the tile turning operation. When the rotating rod 303b is moved in the reverse direction, the rotating block 302c will fall back into the rotating groove 302a and will not be exposed outside the connection frame 301c;

[0055] The entire device effectively avoids the shaking or deviation of the rotor during the lifting process; the design of the entire lifting device fully considers the safety of operation.
