Tool scaffold for cargo oil tank of chemical carrier

Abstract

The invention discloses a tool scaffold for a cargo oil tank of a chemical carrier. The tool scaffold comprises a peripheral tank bulkhead scaffold module and a top inverted-hung scaffold module; the peripheral tank bulkhead scaffold module comprises a plurality of steel angle brackets connected to peripheral tank bulkhead eye plates and a plurality of supporting vertical rods arranged in pairs and vertically arranged on the steel angle brackets, a plurality of steel pipe brackets are connected between each pair of supporting vertical rods from bottom to top at intervals, and the steel pipe brackets and the peripheral tank bulkhead eye plates are fixed; junctions of the steel pipe brackets and the supporting vertical rods are fixed through double-pipe embracing hoop modules; and the top inverted-hung scaffold module comprises a plurality of hanging hook rods and supporting transverse rods, wherein the hanging hook rods are hung on a tank top hanging ring in the oil tank and distributed at intervals, the supporting transverse rods are horizontally connected to the lower ends of the hanging hook rods in a hung mode, and the two ends of the supporting transverse rods are fixedly connected with the supporting vertical rods through the double-pipe embracing hoop modules. According to the tool scaffold, convenience and the efficiency of coating operation in the cargo oil tank are improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a tooling scaffold for cargo oil tanks of chemical tankers. Background technique [0002] The interior of the cargo oil tank of a large chemical tanker needs special coating, specifically, the internal surface of the cargo oil tank is sanded first, and then sprayed with special paint. Due to the large space inside the cargo oil tank, scaffolding needs to be erected inside the cargo oil tank before painting. The traditional method of erecting scaffolding is to use full scaffolding. When erecting, the scaffolding steel pipes need to be erected on the bilge. Since there are many scaffolding steel pipes on the bilge, the sanding and painting cannot be completed at one time. It needs to be removed after the scaffolding is removed. The secondary sandblasting paint was carried out, which resulted in a longer special coating cycle for cargo oil tanks and affected the shipping sched...

Problems solved by technology

The traditional method of erecting scaffolding is to use full scaffolding. When erecting, it is necessary to stand the scaffolding steel pipes on the bilge. Since there are many scaffolding steel pipes on the bilge, the sanding and painting cannot be completed at one time. It needs to be removed after the scaffolding is removed. Carry out secondary sanding and painting, resulting in a longer period of special coating for cargo oil tanks, and affecting the shipping schedule
