Description
Technical field
The invention belongs to suspenders, particularly relate to a kind of inner-supporting type hanger for lifting hollow cylinder.
Background technology
With electric power facility development with it is universal, every profession and trade increasingly increases the demands such as generator, motor, stator
The increasing numbers such as processing, installation, so the demand of special hanger is consequently increased, while as the demand of hollow profile increases
Add, the special equipment of the vertical handling of demand also increases as.
Currently, domestic handling roll bending is using clamping outer circle or is directly lifted with the method that rigging pocket is hung, it is outer when encountering
When the irregular object of shape, the form handling of clamping outer circle can not be just used.It is hung with common rigging pocket, not only efficiency is low, and handling
It is not perfectly flat steady, rigging or suspended object can be also damaged sometimes, be difficult to realize perfection handling installation.
Invention content
The purpose of the present invention is to provide a kind of inner bearing types that can be lifted to the irregular hollow cylinder of shape to hang
Tool.
Inner-supporting type hanger, including platform sling, mechanism for opening/closing, executing agency；The use of wherein each mechanism and parts is tied as follows
Structure：
A, platform sling is a longitudinally disposed stripe board, and top opens up lifting hole(eyelet), and middle part longitudinally offers strip-shaped hole；
B, mechanism for opening/closing includes the suspension hook that top is rotatably assorted with platform sling top, is slidably matched and hang on strip-shaped hole
The axis pin of suspension hook hook-holding part；
C, executing agency includes interior tong arm, the outer tong arm for being axisymmetricly distributed and being stacked with strip-shaped hole, with interior tong arm, outer pincers
The pincers tooth of rolling assembling at the protrusion of arm middle part outside；Axis pin in the top and mechanism for opening/closing of interior tong arm and outer tong arm rotates coaxially
The lower part of assembly, interior tong arm and outer tong arm offers right slideway and left slideway respectively, and the left slideway and right slideway are in scissor
Distribution and bottom end and the assembly of synchronizing shaft coaxially slide, synchronizing shaft are coupled with platform sling bottom, and the working face for clamping tooth is equipped with anti-skid chequer.
The particular technique construction of the present invention also has：Synchronizing shaft in executing agency is adapted to the trepanning that platform sling bottom opens up.
Fixing assembling may be used with the trepanning that platform sling bottom opens up in synchronizing shaft in executing agency, and a variety of positioning sides such as be rotatably assorted
Formula, more preferred and easy mode are the trepanning fixing assemblings that the synchronizing shaft in executing agency is opened up with platform sling bottom.
For the smooth folding of tong arm, outer tong arm in guarantee, multiple structural forms may be used in left slideway, right slideway, wherein
It is preferable in the following way, left slideway and right slideway in executing agency are the arc for being distributed, overlapping in scissor
Shape long slot bore.
For convenience of the work of suspension hook, preferred frame mode is that the suspension hook surface of mechanism for opening/closing is equipped with handle.
It is rotatably assorted by axis pin realization with platform sling top at the top of suspension hook.
Working principle of the present invention is as follows：Crown block hook carries out handling by lifting hole(eyelet) to platform sling, and the top of inside and outside tong arm is logical
It is hinged to cross axis pin, is slided along platform sling strip-shaped hole under Gravitative Loads.The right slideway and left slideway of inside and outside tong arm are along platform sling
Synchronizing shaft sliding, interior tong arm is equivalent to be rotated clockwise along upper suspension centre, outer tong arm be equivalent to along upper suspension centre counterclockwise side
To rotation, in lifting process, circle diameter where pincers tooth gradually increases platform sling, until stretching suspended object inner wall, clamps tooth and quilt
The contact of hanging object inner wall generates frictional force, and suspension hook continues to rise, and lifting force also gradually increases, until lifting force is equal to suspended object weight
Power, lifting force are converted to outer tension by suspender, and outer tension increases the frictional force of pincers tooth and suspended object inner wall, realizes safety
Lifting.
The parts mix selection of the present invention is reasonable, and the structure of scissors tong arm and pincers tooth is dexterously utilized and realizes to by handling
The inner wall of hollow cylindrical object is fixed, and does not form damage to the outer surface of hanging object and lifting is safe and reliable.
Specific implementation mode
