Problems solved by technology

[0008] In view of the above problems, the present invention provides a hoisting tool and a hoisting method for a ring-shaped workpiece. By setting the switch between the outer hoisting gear group and the inner hoisting gear group, the control of the expansion and contraction of the mobile support mechanism is realized, so that the hoisting gear After hoisting the ring-shaped workpiece, it can quickly separate from the ring-shaped workpiece, avoiding the simultaneous heating of the spreader and the ring-shaped workpiece, and solving the technical problem that the traditional spreader cannot quickly separate from the ring-shaped workpiece

Embodiment 1

[0058] Such as Figure 1 to Figure 4 As shown, a ring-shaped workpiece fast hoisting sling is used for hoisting and transferring a pile 10a composed of a plurality of ring-shaped workpieces 10 stacked coaxially, including:

[0059] The outer spreader set 1, the outer spreader set 1 includes a spreader main body 11 and an outer lifting shaft unit 12, the spreader main body 11 is connected to the lower part of the outer lifting shaft unit 12, the spreader main body 11 It includes a cylindrically arranged sleeve portion 111 and a plurality of slide rail portions 112 equidistantly arranged along the circumferential direction of the sleeve portion 111, and the length direction of the slide rail portions 112 is all along the radial direction of the sleeve portion 111. set up;

[0060] The mobile support mechanism 2 is slidably installed on the lengthwise direction of the corresponding slide rail part 112 through a slider 21, and the end of the slider 21 pointing to the shaft center...

Embodiment 2

[0067] Figure 4 It is a schematic structural view of Embodiment 2 of a ring workpiece fast hoisting sling of the present invention; as Figure 4 As shown, the components that are the same as or corresponding to those in Embodiment 1 use the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The Example 2 with figure 1 Example 1 shown differs in that:

[0068] Such as Figure 4 As shown, the outer lifting shaft unit 12 includes:

[0069] Lifting sleeve 121, the interior of the lifting sleeve 121 is hollow, for the insertion of the inner spreader group 3, and the upper end of the lifting sleeve 121 is provided with an outer suspension ring 122;

[0070] The spreader spring sleeve 123, the spreader spring sleeve 123 is coaxially connected and arranged on the lower end of the lifting sleeve 121; and

[0071] The spreader limit sleeve 124, the spreader limit sleeve 124 is coaxially arra...

Embodiment 3

[0076] Figure 5 It is a schematic structural view of Embodiment 3 of a ring workpiece fast hoisting sling of the present invention; as Figure 5 As shown, the components that are the same as or corresponding to those in Embodiment 1 use the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The Example 3 with figure 1 Example 1 shown differs in that:

[0077] Such as Figure 5 to Figure 8 As shown, the slide rail part 112 is provided with a chute 113 for the sliding block 21 to slide, and the bottom of the chute 113 is provided with an installation groove 114 for installing the reset driver 22

Abstract

The invention relates to the technical fields of lifting and transferring of annular workpieces, in particular to a lifting appliance for rapidly lifting annular workpieces and a lifting method. The lifting appliance comprises an outer lifting appliance set, a movable supporting mechanism and an inner lifting appliance set, and the lifting method comprises the steps of stacking, lifting applianceplacement, bearing positioning, lifting and reset separation. Through the arrangement of switching between the outer lifting appliance set and the inner lifting appliance set, the movable supporting mechanism is controlled to expand and contract, so that the lifting appliance can be quickly separated from an annular workpiece after the annular workpiece is lifted, the situation that the lifting appliance and the annular workpiece are synchronously heated is avoided, and the technical problem that a traditional lifting appliance cannot be quickly separated from the annular workpiece is solved.

Description

technical field [0001] The invention relates to the technical field of hoisting and transfer of ring workpieces, in particular to a hoisting tool for fast hoisting of ring workpieces and a hoisting method. Background technique [0002] The spreader is the main tool for moving the products in the factory. The annular workpiece in this application refers to the bearing ring. During the thermal processing of the bearing ring, it is necessary to use the spreader to transfer the bearing ring to the heat treatment furnace for heating. , but the traditional spreader cannot achieve quick detachment after the lifting and transfer of the bearing ring is completed. It is necessary to leave the spreader and the bearing ring in the heat treatment furnace for heating, and there are the following technical problems: [0003] First, it causes the heating speed of the heat treatment furnace to be slow; [0004] Second, the spreader is also heated to increase energy consumption; [0005] Th...
