Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0049] According to the structural characteristics of the tank body, the present invention assembles part of the tank body 1 in the order of inversion, and seals it, and uses a high-flow low-pressure blower to send air into the tank body 1. Since the cross-sectional size of the tank body 1 is uniform Larger, a small pressure difference can generate a huge buoyancy. When the buoyancy generated by the gas in the tank 1 exceeds the mass and friction of the tank 1 to be lifted, the tank 1 will float. When the tank 1 floats When the predetermined height is reached, control the air volume and cooperate with the balance limit device to stop it at the predetermined height, quickly carry out the combination of the upper and lower wall panels, after the spot welding is fixed, stop the wind for formal welding, and the board and so on until complete.

Abstract

The invention provides a high altitude mounting method of pressure transformative gas cap of silo, belonging to the high altitude machine mounting method technical field, and comprising a storage tank body. The mounting method includes the following steps: the mounting and welding of the bottom plate of the tank; the mounting of the inner tube; the mounting of first and the second wainscot and the angle steel for wrapping the edge; the mounting of a central space; the mounting of the tank roof; the removing of the central space; wrapping of the plates to be mounted; mounting of the mouth closing device; mounting of the balancing device; mounting of the sealing device. The invention is a mounting method of storage tank, which adopts the gas cap technology. The method is simple and easily grasped, the working space is wide, the construction period is short, few types of equipment are used, the structure is simple and nonbreakable, and the maintenance is convenient. As the invention is an inverted mounting method of gas cap, large-scale crane and high altitude operations are unnecessary, thereby large amount of falsework is saved, and the operations are safe.

Description

Technical field: [0001] The invention relates to a high-altitude mechanical installation method, in particular to a silo high-altitude variable pressure air cap installation method for on-site fabrication and installation of super high-altitude, large-capacity, circular vaulted cone-bottom steel containers. Background technique: [0002] The traditional upright and upside-down installation method of high-altitude machinery requires large-scale hoisting machinery and sufficient work sites, requires a lot of manpower, high labor intensity, and the lifting speed of high-altitude installation machinery is too slow and low in efficiency. Moreover, hydraulic flipping requires expensive hydraulic devices, and the construction cost is high. Invention content: [0003] The object of the present invention is to provide a method for installing a high-altitude variable pressure air cap of a silo in view of the deficiencies in the prior art. This method is an air-top inversion method,...
