Background
The stator of the motor has large mass, and needs to be installed in the motor when in use, and the stator is of a cylindrical structure consisting of a stator core, a stator winding and a machine base, so that the movement is inconvenient. When the motor stator is moved or installed, the stator is generally lifted up manually, a steel wire rope penetrates through the bottom surface of the stator, and then a loader or a crane is used for hoisting, but the stator is easily collided and damaged. The manual operation also has many potential safety hazards, which brings inconvenience to the installation, especially for large motors, the manual operation cannot be carried out, and mechanical hoisting is necessary.
In order to solve the above problems, people have developed a corresponding hoisting tool, for example, patent CN 201758338U discloses a motor stator hoisting clamp, which is formed by connecting two semicircular clamps with screw holes at two ends through bolts and nuts, wherein two sides of the two semicircular clamps are respectively provided with a lifting lug for placing a hoisting rope, the specification of the semicircular clamps is matched with that of a motor stator to be hoisted, and the hoisting tool of the structure fixes the motor stator through the two semicircular clamps for facilitating hoisting; patent CN 204355965U discloses a hoisting device for a motor stator, which comprises two clamping arms and two connecting pieces, wherein the clamping arms correspond to the connecting pieces one by one, the two clamping arms are hinged together in an X-shaped cross manner, the upper ends of the two clamping arms are rotatably connected with one end of the corresponding connecting piece, the lower ends of the two clamping arms are both provided with clamping parts, and the other ends of the two connecting pieces are rotatably connected together; the hoisting device with the structure can facilitate the assembly of the stator, improve the working efficiency, reduce the labor force, ensure firm locking of the hoop, prevent the stator from falling off when the hoop is matched with a crane to move and ensure safe use; however, the hoisting tools with the two structures have certain defects: the hoisting tool and the stator are connected in an outward holding mode, and during hoisting, gravity is concentrated from two sides of the stator to the middle part, so that unstable hoisting can be caused.
Therefore, it is very necessary to develop a stator internal stay hoisting tool which is safe to use and ensures stable hoisting.
