Multifunctional filling vertical pipe for fluid tank car butt joint

Abstract

The invention discloses a multifunctional filling vertical pipe for fluid tank car butt joint. The multifunctional filling vertical pipe comprises a power driving mechanism, a rotating mechanism, a transmission part and a liquid scraping and supporting mechanism installed on the vertical pipe. The rotating mechanism comprises an outer spiral track moving part, a rotating guide column, an upper spring and a lower spring; the liquid supporting barrel is installed on the liquid supporting barrel supporting device, the liquid scraping and supporting mechanism is composed of a tank opening sealing assembly and a liquid supporting barrel, the tank opening sealing assembly comprises a tank opening sealing cover and a liquid scraping ring, and the liquid scraping ring is embedded in the tank opening sealing cover and forms a whole with the tank opening sealing cover to guarantee that the liquid scraping ring and the vertical pipe are coaxial. And the surface of the vertical pipe is sleeved with the lower spring and moves relatively along with the driving of the elastic force of the lower spring and the upward movement of the vertical pipe, so that the dropping liquid on the outer wall of the vertical pipe is cleaned. The problem that liquid drips from the vertical pipe after loading operation of an existing petrochemical fluid automatic loading device is finished is solved, follow-up of the liquid supporting barrel and the vertical pipe is achieved, independent operation can be achieved, efficiency is high, and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to automatic equipment in the process of fluid loading and unloading in the petrochemical industry. Background technique [0002] At present, domestic and foreign petrochemical fluid automatic loading devices basically adopt telescopic vertical pipe mechanisms driven by pneumatic or hydraulic motors and pulled by wire ropes. Most of them have not solved the problem of dripping when the vertical pipe moves. Liquid, on the one hand, pollutes the vehicle body and the ground, on the other hand, it will bring hidden dangers to the operating safety of the operators, which will inevitably affect the environment and safety of the enterprise. The existing treatment method is to install a liquid holding bucket outside the vertical pipe. After the loading operation is completed, the liquid holding bucket needs to be manually operated to rotate the liquid holding bucket to the bottom of the vertical pipe, and the dripping liquid on the inner ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a multi-functional filling vertical pipe for fluid tanker docking, which solves the problem of liquid dripping from the vertical pipe after the loading operation of the current petrochemical fluid automatic loading device, and realizes the random connection between the liquid holder and the vertical pipe. It can be operated independently, with high efficiency and no potential safety hazard
