Description

Technical Field

[0001] The present invention belongs to the field of lifting tools, and particularly relates to a special lifting device for the shaft-type agitator paddle of rare earth smelting equipment. Background Art

[0002] Traditional lifting mechanisms mostly use hooks to hang on machinery and are fixed with steel wire ropes or lifting belts. When lifting circular materials, it is necessary to use steel wire ropes or lifting belts for multiple bundlings, or to lift them after clamping with single-point claws. The operation is very inconvenient, and the safety cannot be guaranteed. There is no place on some extractors and precipitation equipment that can cooperate with the hook, so it can only be lifted by clamping it with a steel wire rope. However, when lifting a single and long agitator paddle, at least two bundling points or two clamping points are required for lifting to prevent imbalance and slipping. Finding the center of gravity of the long material and the reasonable positions of the two bundling points or clamping points takes a long time, which brings great inconvenience to the operation and there is also a safety risk caused by imbalance, seriously affecting the operation safety. At the same time, the clamping operation will affect the surface roughness of the components. Especially during equipment maintenance, if the clamping is not tight, the workpieces such as the agitator paddle will fall off and cause damage, thus reducing the work efficiency and not meeting the use requirements. Summary of the Invention

[0003] The purpose of the present invention is to provide a special lifting device for the shaft-type agitator paddle of rare earth smelting equipment to solve the deficiencies in the lifting of existing extractors and precipitation equipment.

[0004] To achieve the above purpose, the technical solution used in the present invention is:

[0005] A special lifting device for the shaft-type agitator paddle of rare earth smelting equipment, comprising: a lifting lug, a connecting handle, a first connecting sleeve, a second connecting sleeve, a pin, a first semi-circular clamping block, a second semi-circular clamping block, and a screw; the connecting handle is connected to the bottom end of the lifting lug, the top of the first semi-circular clamping block is connected to the bottom end of the connecting handle, two first connecting sleeves are respectively connected to the outer walls of the first semi-circular clamping block and the second semi-circular clamping block, and two second connecting sleeves are respectively connected to the outer walls of the first semi-circular clamping block and the second semi-circular clamping block; the two first connecting sleeves are opposite in position, the two second connecting sleeves are opposite in position, the inner wall of the second connecting sleeve is provided with internal threads, the pin is sleeved in the two first connecting sleeves, and the screw is connected to the two second connecting sleeves; the bottom end of the first semi-circular clamping block is provided with a semi-circular first half-ring, and the bottom end of the second semi-circular clamping block is provided with a semi-circular second half-ring.

[0006] Furthermore, the first semi-circular clamping block and the second semi-circular clamping block are opposite in position, and the first half-ring and the second half-ring are opposite in position.

[0007] Furthermore, the two first connecting sleeves are respectively connected to the opening edges of the first semi-circular clamping block and the second semi-circular clamping block, and the two second connecting sleeves are respectively connected to the opening edges of the first semi-circular clamping block and the second semi-circular clamping block.

[0008] The technical effects of the present invention include:

[0009] The present invention is applicable to shaft-like objects with radial grooves on the sling. The first half-ring and the second half-ring of the hoisting device are connected to the shaft-like object by a card slot, with flexible rotation and convenient operation. The two semi-circular clamping blocks are connected together in the form of a hinge, with stable connection. The inner hole forms a clamping ring with an annular structure, increasing the contact area between the clamping block and the radial card slot of the shaft, thereby increasing the fixing force between the clamping block and the card slot of the shaft.

[0010] During the hoisting process, the device of the present invention does not contact the outer edge surface of the shaft at all, preventing scratching of the important surface and affecting the fitting accuracy. At the same time, no radial force is generated during hoisting, preventing bending deformation.

[0011] The present invention has higher efficiency and convenience. The hoisting device can improve the efficiency of the hoisting process and increase the convenience of operation, can easily move the hoisted object, and reduce the manpower requirement for the operator.

[0012] The present invention is easier to operate for setting up and disassembling, and does not require professional tools or technical support.

[0013] The present invention has a lower cost and maintenance cost, with the advantages of low cost and maintenance cost. The common 45# steel material with low price and durability is selected, and the volume is more compact and small. Description of the Drawings
