Clamping structure-based double-charging-barrel hoisting device and method

Abstract

The invention discloses a clamping structure-based double-charging-barrel hoisting device and method, and relates to the technical field of hoisting. The hoisting device comprises an upper charging barrel and a lower charging barrel, wherein the upper end of the upper charging barrel is of an open structure; a plurality of clamping strips are evenly distributed and fixed to the outer side wall of the lower end of the upper charging barrel in the annular direction; the lower discharging barrel is arranged below the upper charging barrel, and the upper end of the lower discharging barrel is of an open structure; a plurality of inlet and outlet notches are uniformly formed in the edge of the upper port of the lower discharging barrel in the annular direction, and the inlet and outlet notches are vertically arranged; a communicating clamping notch is vertically formed in the bottom surface of each inlet and outlet notch; and the plurality of clamping strips are in one-to-one correspondence with the plurality of inlet and outlet notches. On the basis of the clamping strip and clamping groove structure, the clamping strips penetrate through the inlet and outlet notches and are clamped in the clamping notches, so that connection of the upper charging barrel and the lower charging barrel is achieved; synchronous hoisting of the upper charging barrel and the lower charging barrel is achieved through movement of an electric hoist on a directional sliding rail; and the connecting efficiency and the hoisting effect of the upper charging barrel and the lower charging barrel can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of hoisting, and in particular relates to a double-barrel hoisting device and method based on a clamping structure. Background technique [0002] Airgel is known as the "miracle material that changes the world", also known as the "ultimate thermal insulation material", and is currently the lightest solid material. Airgel is a material with a three-dimensional nano-network porous structure, which has a low density (0.03-0.1g / cm 3 ), high specific surface area (500~1200m 2 / g), high porosity (80~99.8%), low dielectric constant (k=1.0~2.0), low thermal conductivity (0.005~0.02W / (m.K)), etc. , sound insulation and noise reduction, optics, electricity and other fields have broad application prospects. [0003] At present, there are two drying processes for preparing airgel products: supercritical drying and atmospheric pressure drying, and these two processes usually need to be completed in a cylindrical dryin...

AI Technical Summary

Problems solved by technology

For the supercritical drying process, due to the need for a high-pressure environment, usually the diameter of the kettle body will not be made very large, but will expand in the length direction, and the lengthening of the drying kettle body will bring a series of lifting problems. The traditional connection between barrels The method adopts the bolt connection method, but it often happens that the bolts are dislocated and deformed after being dried at high temperature and cannot be disassembled. Therefore, how to solve the problem of rapid lifting and disassembly of the vertical double barrel becomes the key to the problem.
