Quick construction device for inner wall of arch crown oil tank

Abstract

The invention relates to a quick construction hanger for an inner wall of an arch crown oil tank. The quick construction hanger comprises a supporting frame with height equivalent to the height of the inner wall of the oil tank, wherein universal wheels and brake mechanisms are arranged at the bottommost layer of the supporting frame; a combined stand column is vertically sleeved in a central manhole in the upper end of the oil tank and comprises a plurality of column jackets which are mutually sleeved and butt-jointed; the column jacket at the topmost end and the column jacket at the bottommost end are provided with thrust bearings respectively; the upper end of the combined stand column is fixed to the outer edge of the manhole, and the lower end of the combined stand column is provided with an adjustable lifting mechanism; and the combined stand column is fixed to the supporting frame through a connecting rod. According to the quick construction hanger, a sunken steel pipe in the manhole in the center of the arch crown on the upper part of the oil tank is used as the stand column, the stand column is utilized as a selection axis, and the bracket is connected with the stand column through the connecting rod and 360-degree random selection and brake positioning can be realized, so that the quick construction hanger has a simple structure and is rational in design. The stability and the safety are improved, the working period is greatly shortened, a large number of scaffolds and labor cost can be saved, and the quick construction hanger can be repeatedly used, has obvious economic benefit and is suitable for being widely implemented.

Description

technical field [0001] The invention relates to an auxiliary tool for the construction field of the inner wall of a building, in particular to a rapid construction device for the inner wall of a vault oil tank. Background technique [0002] Steel oil tanks used in oil fields are relatively large, usually with a volume of 500m 3 ~30000m 3 , when the inner surface is subjected to anti-corrosion treatment, as well as the installation of radiographic flaw detection and electrical instrument accessories, high-altitude operations are required. The existing construction methods usually use a full house of scaffolding (stacked together to form a circle), and the number of scaffolding used is huge. Sporadic installation, testing, quality inspection, etc. need to be carried out, which is time-consuming and laborious. It usually takes more than 20 workers and more than ten days to complete the assembly. The construction period is long, and a lot of scaffolding and labor costs are wast...
