Heavy fixture suitable for transfer of cylindrical thin shell and application method thereof

Abstract

The invention discloses a heavy fixture suitable for transfer of a cylindrical thin shell and an application method thereof. The furniture comprises a base, clamping jaws and power devices for pushingand pulling the clamping jaws, wherein the bottom of the base is provided with an arc-shaped clamping plate, the shape of the clamping jaws is matched with the shape of the arc-shaped clamping plate,the pair of clamping jaws are symmetrically connected to the bottom of the base relative to the arc-shaped clamping plate, the upper ends of the two clamping jaws are hinged with the power devices, the arc-shaped clamping plate at the bottom of the base simultaneously serves as a sliding rail during movement of the clamping jaws, and the power devices push the clamping jaws to move along the sliding rail so as to realize the operation of clamping and loosening a product. The clamping jaws can almost slide to the maximum coated clamping position against the outer wall of the cylindrical thin shell, so that guarantee is provided for safe and stable hoisting and transfer of the product; the clamping jaws can slide along the outer wall of the cylindrical thin shell, so that the fixture can clamp the cylindrical thin shell under the condition that the space gap is small; and a matched rigid hoisting mechanism can enable a travelling crane or a crane to stably and safely hoist the cylindrical thin shell under the condition that the space gap is small.

Description

technical field [0001] The invention relates to a hoisting fixture, in particular to a heavy-duty fixture suitable for the transfer of cylindrical thin shells and an application method thereof. Background technique [0002] In the process of transshipment of large cylindrical thin shell products, hoisting is required, but due to its large aspect ratio, usually several meters or even tens of meters long, it is affected by space constraints during hoisting, and the weight can reach several Ten tons, but the shell is thin, so the general lifting fixture cannot be directly applied. [0003] At present, the transfer of large cylindrical thin shell products mainly adopts manual hoisting, but due to the above characteristics of this type of product, the equipment for manual hoisting generally uses cranes or cranes, which are lifted by wire ropes, and wire ropes It is a flexible body, and there is a situation of wobbling and instability during the lifting process, which is prone to...

AI Technical Summary

Problems solved by technology

When transferring from the vehicle after being transported to the designated place, it is also impossible to use the driving and crane to lift it, because when using the driving or crane to lift, it is necessary to manually use the sling to wrap the product radially. Obviously, the distance between the product and the compartment wall is very large Inoperable in small cases

Moreover, general lifting fixtures cannot operate in a narrow gap space to clamp and lift large cylindrical thin shell products.
