Example 3:
fig. 5 is a schematic structural diagram of an embodiment 3 of a rapid hoisting sling for annular workpieces according to the present invention; as shown in fig. 5, in which the same or corresponding components as those in embodiment 1 are denoted by the same reference numerals as those in embodiment one, only the points of difference from embodiment 1 will be described below for the sake of convenience. This embodiment 3 differs from embodiment 1 shown in fig. 1 in that:
as shown in fig. 5 to 8, a sliding groove 113 for sliding the sliding block 21 is provided in the sliding rail portion 112, and a mounting groove 114 for mounting the reset driving member 22 is provided at the bottom of the sliding groove 113

This embodiment 4 differs from the embodiment 3 shown in fig. 5 in that:
as shown in fig. 10 and 11, a positioning step 231 for supporting and limiting the annular workpiece 10 at the bottom of the pile 10a is provided at an end of the moving body 23 facing away from the slide rail portion 112.
Further, the positioning step 231 is arranged in an arc shape with the side wall against which the annular workpiece 10 abuts.
It should be noted that, when the moving body 23 moves below the pile 10a, the positioning step 231 is engaged with the inner wall of the annular workpiece 10 at the bottommost layer of the pile 10a to realize the load bearing of the whole pile 10a, and it should be emphasized that, in the process of engaging the moving body 23 with the pile 10a to realize the load bearing, the engaging pressure between the positioning step 231 of the moving body 23 and the pile 10a is completely dependent on the whole mass of the pile 10a, the larger the mass of the pile 10a is, the larger the force of the pile acting on the cone 31 is when the inner spreader group 3 is pulled, the larger the force of the cone 31 abutting against the slider of the slider 21 is, the larger the engaging pressure of the moving body 23 against the pile 10a is, and vice versa, which realizes the self-adjustment of the grasping strength of the annular workpiece, and ensures the stability of the annular workpiece 10 in the lifting process.
It is further noted that, the positioning step 231 and the side wall of the annular workpiece 10 abutting against each other are arranged in an arc shape, so that the moving body 23 can avoid damaging the smoothness of the inner side wall of the annular workpiece 10 during the bearing process.
Example 5:

Example 6:
a hoisting method of a rapid hoisting hanger for annular workpieces according to embodiment 6 of the present invention will be described with reference to embodiments 1 to 5.
As shown in fig. 12, the method comprises the following steps:
stacking, namely coaxially stacking a plurality of annular workpieces 10 on sizing blocks 101 which are arranged at equal intervals on the circumference to form a stock pile 10a, wherein adjacent annular workpieces 10 are separated by a cylindrical support 102;
step two, placing a lifting appliance, hooking an outer lifting ring 122 on an outer lifting appliance group 1 through a lifting device, lifting and transferring the whole lifting appliance into an inner ring of the material pile 10a, and enabling a movable supporting mechanism 2 for carrying and lifting the material pile 10a to be in a contraction state;
carrying and positioning, namely switching a lifting device from hooking the outer lifting ring 122 to hooking the inner lifting ring 33 on the inner lifting tool group 3, lifting the inner lifting ring 33 upwards, so that the cone 31 connected with the inner lifting ring 33 through the inner lifting shaft 32 is lifted upwards synchronously, and the cone 31 is in sliding interference fit with the movable supporting mechanism 2, so that the movable supporting mechanism 2 is expanded to the lower part of the material pile 10a along the length direction of the sliding rail part 112 in an outward sliding manner, and the material pile 10a is carried;
hoisting, namely, a hoisting device hooks the inner hoisting ring 33 to continuously lift upwards, and hoists and transfers the material pile 10a through the movable supporting mechanism 2 to separate from the sizing block 101; and
and step five, resetting and separating, namely after the material pile 10a is lifted, transferred and placed on the sizing block 101 at the designated position, switching the lifting device from hooking the inner lifting ring 33 to hooking the outer lifting ring 122, enabling the cone 31 to fall down, enabling the mobile supporting mechanism 2 to be retracted inwards by virtue of the reset driving piece 22 for resetting, lifting the lifting device, and separating the whole lifting appliance from the inner ring of the material pile 10 a.
In step one, the annular workpieces 10 in the present application refer to bearing rings, the annular workpieces 10 need to be transferred to a heating furnace for heat treatment after being stacked into a material pile, and in order to ensure the airflow between the annular workpieces 10, the annular workpieces are separated by the support 102, so that the cavities can be flowed, and the heat treatment is ensured to be performed.
It is further noted that, in the second step, when the lifting appliance is placed, since the movable supporting mechanism 2 is in the contracted state at this time, the overall external dimension of the lifting appliance is much smaller than the inner diameter of the annular workpiece 10, and the lifting appliance can be smoothly placed into the inner ring of the annular workpiece 10 without any interference.
It should be further noted that, in the third step, when the material pile 10a is supported, the movable supporting mechanism 2 is expanded outwards at the same time, and since the lifting appliance is not necessarily located at the axis of the inner ring of the annular workpiece 10 when being placed, the movable supporting mechanism 2 can be adjusted by multi-point touch, so that when the lifting appliance lifts the material pile 10a, the lifting appliance is located at the axis of the annular workpiece 10, and the balance of the stress of the lifting appliance is ensured.
Furthermore, in step five, the movable support means 2 is retracted and returned by the return actuator 22, the return actuator 22 preferably being a spring element, the return actuator 22 being compressed when the movable support means 2 is expanded, and the return actuator 22 releasing the elastic compression when the movable support means is retracted.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
