Description

TECHNICAL FIELD

[0001] The utility model belongs to tank car cleaning equipment technical field, concretely relates to a tank car oil scraping device. BACKGROUND

[0002] Train tank car is the main tool for transporting petrochemical products, and undertakes the transportation task from crude oil to various chemical products. However, during the transportation process, a large amount of oil stains often accumulates at the bottom of the tank car, which not only comes from the transported petrochemical products itself, but also may include sediments, moisture and impurities during the transportation process. These oil stains are usually sticky and difficult to remove by simple flushing or natural flow, which brings great challenges to the cleaning work of the tank car.

[0003] The traditional tank car cleaning method mainly relies on manual tank car scraping operation. However, this method not only has low efficiency, but also has serious safety hazards. The internal space of the tank car is small, the ventilation is poor, and there may be toxic and harmful gases or flammable and explosive substances left. The workers work in the limited space for a long time, not only the physical consumption is huge, but also face the high risk of poisoning, suffocation, fire and explosion. In addition, due to the sticky and difficult to remove oil stains, manual scraping often cannot achieve the ideal cleaning effect, which is easy to leave dead angles and residues, affecting the subsequent use of the tank car and the product quality.

[0004] In order to solve the safety hazards and low efficiency of manual tank scraping during the cleaning process of train tank car, it is particularly important to develop a high-efficiency and safe tank scraping device. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at least to solve one of the technical problems existing in the prior art, and provides a tank car oil scraping device, which adopts the technical scheme as follows:

[0006] A tank car oil scraping device, comprising a tank mouth cover plate assembly, a tank mouth locking mechanism is fixed on the tank mouth cover plate,

[0007] The tank mouth locking mechanism comprises a cylinder, a hollow shaft rotating groove, a lock tongue and a locking rod. The cylinder is used as the drive to drive the internal locking rod to move upward and rotate around the hollow shaft rotating groove to the lower part of the tank mouth and lock. The upper part of the tank mouth cover plate assembly is connected with the lifting driving mechanism, and the middle part is connected with the oil suction fixed pipe.

[0008] The lower part of the lifting driving mechanism is connected with the up-down moving rod, and the lifting driving mechanism is a left-right symmetrical structure.

[0009] The beneficial effects of the utility model are as follows: through the structural design, the oil stains at the bottom of the tank car can be quickly cleaned, manual operation is replaced, and the generation of cleaning danger is reduced; since the whole device is automatically designed, the whole working efficiency is significantly improved, and the cleaning effect is remarkable in the actual application process.
