Cleaning vehicle for cleaning welding seams on inner wall of steel storage tank

Abstract

The invention discloses a cleaning vehicle for cleaning welding seams on the inner wall of a steel storage tank. The cleaning vehicle comprises a chassis, the two sides of the chassis are each connected with a set of travelling device capable of driving the chassis to move along the inner wall of the storage tank, and the travelling devices are arranged symmetrically. The chassis is provided with a cleaning device, a dust collection mechanism, a sampling pan-tilt and illuminating lamps, wherein the cleaning device is located in the middle of the chassis and used for cleaning the inner wall of the storage tank; the dust collection mechanism is located on the cleaning object discharging side of the cleaning device and used for collecting cleaning objects; the sampling pan-tilt is located in the position, away from the cleaning object discharging side, of the cleaning device and used for monitoring the cleaned inner wall of the storage tank; and the illuminating lamps are located on the two sides of the sampling pan-tilt correspondingly and used for sampling lighting. According to the cleaning vehicle for cleaning the welding seams on the inner wall of the steel storage tank, workers are replaced with the cleaning vehicle to clean the inner wall of the storage tank, operation is easy, any additional pollution is avoided, and cleaning work is not limited by the height and the size of the storage tank; thus, the working environment of the workers is greatly improved, and the physical health and the life safety of the workers are ensured; and the cleaning efficiency is high, time and effort are saved, expansive large-size cleaning equipment is not needed any more, and a large amount of cost is reduced.

Description

technical field [0001] The invention relates to a vehicle for cleaning the inner wall of a steel storage tank. In particular, it relates to a cleaning vehicle suitable for cleaning and anticorrosion of round steel containers and used for cleaning welds on the inner wall of steel storage tanks. Background technique [0002] Many circular containers, such as large and medium-sized boilers, containers for liquid nitrogen, chlorine, etc., are special equipment, and annual inspections must be carried out on their welds. Due to the harsh internal environment of the container, there will be thick and difficult to clean rust, etc., so the weld seam on the inner wall must be cleaned before the inspection. At present, this cleaning work is mainly done manually. Because the manhole on the container is usually only 600mm×600mm, the diameter is small, and the working environment of the workers is very harsh, especially the container containing toxic gas, which will also cause damage to ...

Problems solved by technology

At present, this cleaning work is mainly done manually, because the manhole on the container is usually only 600mm×600mm, the diameter is small, and the working environment of the workers is very harsh, especially the container containing toxic gas, which will also cause damage to the worker’s body

However, the existing cleaning equipment is huge and cannot work inside the storage tank at all.
