Anti-electrostatic crane tube telescopic oil drain device

Abstract

The invention relates to an anti-electrostatic crane tube telescopic oil drain device, nylon is taken as material of a telescopic sleeve, a connecting tube is welded at the lower end of a crane tube, a fixed tube is in threaded connection with the connecting tube, a shoulder is arranged at the lower end of the fixed tube, the telescopic sleeve consists of a plurality of levels by mutual sheathing, the shoulder is arranged at the lower end of each level of the telescopic sleeve, the plurality of levels of the telescopic sleeves are mutually hung at the shoulders, the first level of the telescopic sleeve is sheathed outside the fixed tube, the lower end of a spring is hung on the lower side outside the lowest level of the telescopic sleeve, the upper end of the spring is hung on a spring bracket, the spring bracket is welded on the connecting tube, the lower end of a support is fixed outside the lowest level of the telescopic sleeve, the upper end of the support is hung on a hanging rod, the hanging rod is fixed on the crane tube, a seal ring is mounted between each two levels of the telescopic sleeves, and the seal ring is mounted between the fixed tube and the first level of the telescopic sleeve. The plurality of levels of the telescopic sleeves are combined together and can contract and expand, thereby meeting the requirement on extending into an inlet of an oil pulling tank truck; and the telescopic sleeve is made of the nylon material, thereby avoiding producing static electricity when in contact with the inlet of the oil pulling tank truck, preventing combustion of combustible gas and explosion, and avoiding economic loss, personal injuries and accidents.

Description

technical field [0001] The invention belongs to equipment for transferring crude oil in an oil field, and is an oil discharge device installed on an oil storage tank, in particular to a telescopic oil discharge device for an antistatic crane tube. Background technique [0002] At present, the crane pipe oil discharge pipeline of single well oil storage tank adopts rubber threaded pipe. After a certain period of use, the spiral steel wire in the rubber threaded pipe is easy to be exposed, and static electricity is easy to be generated when the oil tank truck entrance is contacted and rubbed, which is easy to ignite the tank Combustible gas can cause an explosion, resulting in major economic losses and personal injury accidents. Therefore, there is a relatively large safety hazard in the existing crane pipe oil discharge pipeline. Contents of the invention [0003] The purpose of the present invention is to design a telescopic oil discharge device for anti-static crane pipes...
