Description
Technical Field
The utility model relates to an installation of motor, concretely relates to lifting device of motor line stator.
Background
Patent document with the publication number of CN 210973549U discloses a wire stator hoisting tool, which includes a connecting center rod 10 and a plurality of limiting support units 20; the connecting central rod consists of an upper supporting rod 11 at the upper part, a middle supporting rod 12 at the middle part and a connecting threaded rod 13 at the lower part; a movable driving block 16 is vertically sleeved on the upper supporting rod; an upper limiting block is formed at the upper end of the upper supporting rod 11; the upper supporting rod is sleeved with a pressure spring 15.
When the tool is used, the movable driving block 16 is lifted upwards to enable the limiting supporting block 24 to approach the central rod 10, and the overall diameter of the tool is smaller than the inner diameter of the linear stator. Then, the wire stator hoisting tool is axially inserted into the wire stator, then the movable driving block is released, the limiting supporting block 24 is tightly attached to the inner wall of the wire stator under the action of the pressure spring 15, and the hoisting equipment is used for upwards lifting and connecting the central rod, so that the hoisting of the wire stator is completed.
The limiting support block 24 can be tightly supported on the inner wall of the line stator and completely depends on the pressure spring 14. If the pressure spring has large elasticity, an operator is difficult to lift the movable driving block 16, so that the tool releases the wire stator; if the elasticity of the pressure spring is small, the limiting support block 24 is difficult to support tightly on the inner wall of the linear stator.
SUMMERY OF THE UTILITY MODEL
The utility model solves the technical problem that: the wire stator hoisting tool is moderate in elasticity of the pressure spring, but can tightly support the limiting supporting block on the inner wall of the wire stator.
In order to solve the technical problem, the utility model provides a following technical scheme: motor wire stator's hoist and mount frock, including well core rod, the movable assembly on well core rod upper portion of movable fit, with the lower connecting rod of well core rod sub-unit connection, the last connecting rod of being connected with last movable assembly, the cooperation is at the pressure spring that well core rod upper portion and bottom offset with last movable assembly, connect the spacing shoe of connecting rod and lower connecting rod, well core rod includes the upper portion thin rod, the swivel sleeve of movable fit on the thin rod of upper portion, with the thick pole of the thin rod fixed connection's of upper portion lower part, the lower part of swivel sleeve is equipped with the external screw thread, it is equipped with can with external screw thread complex internal thread to go up movable assembly.
When the tool is used, the upper movable assembly is lifted upwards to enable the limiting supporting block to be close to the central rod, and the overall diameter of the tool is smaller than the inner diameter of the linear stator. Then, insert the frock axial in the linear stator, then, release the activity subassembly, under the effect of pressure spring, spacing supporting shoe and linear stator inner wall contact, moreover, the external screw thread that goes up the activity subassembly and the swivel sleeve lower part that descends along well core rod is close. Then, the operator rotates the rotating sleeve to enable the external thread on the rotating sleeve to be in threaded connection with the internal thread on the upper movable assembly. The process of the screw connection enables the upper movable assembly to further descend, and the upper connecting rod further supports the limiting supporting block on the inner wall of the linear stator. And then, lifting the central rod upwards by using a lifting device to finish the lifting of the linear stator.
The elasticity of the pressure spring only needs to enable the upper movable assembly to move downwards along the central rod, so that the limiting support block is in contact with the inner wall of the linear stator, the internal thread of the upper movable assembly is close to the external thread of the rotary sleeve, and the task of supporting the inner wall of the linear stator by the limiting support block is completed by the rotation of the rotary sleeve. So, not only limit support block can prop up line stator inner wall, moreover, this kind of tight state of propping can be kept at line stator in-process of lifting by crane.
When the wire stator is released, an operator rotates the rotary sleeve reversely, the external thread on the rotary sleeve is separated from the internal thread of the upper movable assembly, and the operator lifts the upper movable assembly upwards. Because the elasticity of the pressure spring is not large, an operator can easily lift the upper movable assembly.
