Detailed Description

In fig. 1, the invention is composed of a telescopic rod, a support rod 5, a sliding sleeve 6, a hoisting main rod 7 and a hoisting ring 9; the telescopic rod consists of a telescopic rod near-end component 1, a telescopic rod pin 2, a telescopic rod far-end component 3 and a telescopic rod tail-end component 4.

The hoisting ring 8 is hung on a crane hook and is fixedly connected with the hoisting main rod 7, and the hoisting main rod end component 11 is fixed at the lower end of the hoisting main rod 7.

Sliding sleeve 6 cover is on hoisting mobile jib 7, can be free slide on hoisting mobile jib 7, and sliding sleeve 6 external fixation has 3 and above bracing piece 5, and sliding sleeve 6 drives bracing piece 5 and slides from top to bottom along hoisting mobile jib 7.

The outermost end of each support rod 5 is connected to a hole in the middle of the distal assembly of telescopic rods 3 by an upper pivot pin 9, by which the distal assembly of telescopic rods 3 can be pivoted.

The hole in the telescopic link distal end subassembly 3 outside is connected with telescopic link near-end subassembly 1 through telescopic link round pin 2, is equipped with both ends confined waist type hole on the telescopic link near-end subassembly 1, when the telescopic link round pin 2 slides in the waist type hole on telescopic link near-end subassembly 1, has realized the change of telescopic link near-end subassembly 1 and telescopic link distal end subassembly 3 furthest apart from, has realized flexible function promptly.

The telescopic rod near-end component 1 is connected with the hoisting main rod stop end component 11 through the lower rotating pin 10, so that the relative rotation of the telescopic rod near-end component 1 and the hoisting main rod stop end component 11 can be realized.

The telescopic link distal end subassembly 3 outside is equipped with the terminal subassembly 4 of telescopic link, and the terminal subassembly 4 of telescopic link is promptly be used for with the joint portion of treating hoist and mount spare part tang looks adaptation, and the terminal subassembly 4 of telescopic link is soft in the spare part in ground of quality, and possesses certain elasticity.

In fig. 2, sliding sleeve 6 down slides along hoisting mobile jib 7, drive telescopic link distal end subassembly 3 and rotate and the downstream, sliding sleeve 6 and hoisting mobile jib end subassembly 11 between the distance reduce, telescopic link round pin 2 slides in the waist type hole on telescopic link near-end subassembly 1, along with the effect of round pin 10 is changeed to the lower part, the angle grow between telescopic link near-end subassembly 1 and hoisting mobile jib 7, the angle that drives telescopic link distal end subassembly 3 changes together, telescopic link end subassembly 4 removes to the direction of principle hoisting mobile jib 7. The plurality of telescopic rods change synchronously, and the diameter of a circle formed by the outer sides of the telescopic rod end components 4 (hereinafter referred to as the outer circle diameter of the hanger) is increased.

In fig. 3, state one: the state of packing up, the distance between sliding sleeve 6 and hoisting mobile jib tang subassembly 11 is great on the hoist promptly, and hoist outside circle diameter is less than spare part tang diameter, and the crane descends, and the hoist moves down, and telescopic link end subassembly 4 descends under the product tang.

In fig. 4, state two: the expansion in-process removes the external force of exerting on sliding sleeve 6 promptly, and sliding sleeve 6 is close to hoist and mount mobile jib ending subassembly 11 under the action of gravity this moment, and hoist outside circle diameter increases gradually.

In fig. 5, in the state three, after the external force applied to the sliding sleeve 6 is removed, the sliding sleeve 6 continues to be close to the main hoisting rod stop end assembly 11, the outside circular diameter of the hanger increases until the outside circular diameter of the hanger meets the inner wall of the part or increases to the limit, the sliding sleeve 6 stops moving, and at this time, the outside circular diameter of the hanger is greater than the diameter of the part stop opening. In the process, even if the diameter of the inner wall or the seam allowance of the part is changed to a certain extent, the diameter of the outer circle of the lifting appliance can be continuously adjusted under the action of the sliding sleeve 6 until the sliding sleeve 6 stops moving.

In fig. 6, the telescopic rod terminal assembly 4 is softer than the component and has certain elasticity, and even if the outer side circle diameter is increased at a higher speed, the telescopic rod terminal assembly 4 slides or collides with the inner wall, and the component and the hanger cannot be damaged after the outermost side of the telescopic rod terminal assembly 4 contacts the inner wall of the component.

In fig. 7, the hoisting hook pulling hoisting ring 8 is lifted upwards, the lifting appliance is moved upwards integrally, the diameter of the outer side circle of the lifting appliance is always larger than the diameter of the part seam allowance opening, the upper part of the outermost side of the telescopic rod distal end component 3 can be attached to the inner wall surface positioned at the lower part of the part seam allowance opening, the part is lifted along with the integral upward movement of the lifting appliance, and the lifting is realized.

The support rod 5 is arranged in the lifting appliance, so that the position of the far end of the telescopic rod tail end component 4 is not lower than the upper non-rotating pin 9, and the downward force applied by the parts at the far end of the telescopic rod tail end component 4 is combined, so that the lifting appliance is prevented from returning to the retracted state in the lifting and transferring processes.

After the hoisting is finished, the part is hoisted to the designated position, the crane hook descends, the downward force applied to the far end of the telescopic rod tail end component 4 by the part disappears gradually, the lifting appliance can be changed into the state shown in fig. 5, an upward force is applied to the sliding sleeve 6 at the moment, the sliding sleeve 6 is far away from the hoisting main rod end stopping component 11, the diameter of the circle outside the lifting appliance is reduced gradually, the state in the expanding process of fig. 4 is changed into the retracting state shown in fig. 3 gradually, the diameter of the circle outside the lifting appliance is smaller than the minimum diameter of the part end stopping part at the moment, the lifting appliance can be completely separated from the part, and the whole hoisting.

When the spare part inner wall that needs hoist and mount is when the casting face of roughness, because telescopic link end component 4 is softer and possess certain thickness, combine spare part dead weight can provide ascending frictional force to rough inner wall surface, when frictional force was big enough, the hoist also can promote spare part through frictional force.
