Description

Stator internal stay lifting device

Technical Field

The utility model belongs to the technical field of lifting device, in particular to stator internal stay lifting device.

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.

Disclosure of Invention

The utility model discloses a main aim at provides a stator internal stay lifting device to overcome prior art's is not enough.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an embodiment of the utility model provides a stator internal stay lifting device, it includes

The connecting base comprises a circular base and a threaded connecting rod, the threaded connecting rod is vertically arranged in the center of the circular base, and the top of the threaded connecting rod is hinged with a hanging ring;

the support base is sleeved on the threaded connecting rod at the upper part, and the threaded connecting rod between the support base and the round base is further sleeved with a buffer assembly;

hang the foot subassembly, hang the foot subassembly including setting up the foot base that hangs between buffering subassembly and support pedestal hang evenly on the outer circumference of foot base along its circumferencial direction and have at least three and hang the foot, hang the foot and be rectangular form, the equal swing joint in bottom that each hung the foot has the ear foot that is used for the bearing, just hang the foot and hang the foot base and pass through hinge structure and be connected.

Furthermore, the circular base is also movably connected with a U-shaped limiting plate which is correspondingly arranged with the hanging foot, and the hanging foot is arranged in a U-shaped cavity of the U-shaped limiting plate.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses stator internal stay lifting device, the bracing piece through frame support piece is fixed with the inside connection of stator frame, and the ear foot of hanging foot subassembly is closely laminated with the stator winding inside and is fixed, adopts dual fixed connection structure, has guaranteed the fastness of connection between lifting device and the stator greatly, can effectively avoid the stator to take place to drop in the hoist and mount process, safe in utilization; meanwhile, a similar triangular hoisting structure is adopted, so that the gravity can be dispersed from the center to the side part, and the stable hoisting is effectively ensured;

(2) the utility model discloses prop lifting device in stator, wherein, still swing joint has and hangs the U type limiting plate that the foot corresponds the setting on the circular base, through setting up U type limiting plate, avoids hanging the foot unlimited to the lateral part struts, causes to strut the degree and is greater than the stator winding internal diameter, damages stator winding.
