Description

Technical Field

[0001] The utility model belongs to the crane pipe technology, and in particular relates to a submerged oil filling crane pipe sleeve with an anti-winding function and used for submerged oil filling. Background Art

[0002] The crane pipe is a device for conveying fluids, especially used when docking with tank trucks during loading and unloading of liquid media. According to the relevant provisions of the national standard "General Guidelines for Preventing Electrostatic Accidents", the crane pipe should be less than 200mm from the bottom of the tank when filling oil, so as to achieve complete underwater loading, effectively reduce oil splashing and volatilization loss, and prevent static electricity. Therefore, the crane pipe must not only meet the requirements of underwater oil filling, but also meet the elevation of the crane pipe so that the tank truck can enter safely, and shorten the length of the crane pipe, that is, the crane pipe casing must be able to move up and down without power. Generally, a counterweight is set in the crane pipe to balance the weight of the casing. When filling oil, the counterweight and the wire rope will often get entangled and stuck under the action of the oil flow, making the casing unable to retract.

[0003] Therefore, a submerged oil loading crane pipe casing with an anti-winding function which has a simple structure, can effectively prevent the entanglement of the counterweight and the wire rope, and is stable during long-distance transportation is proposed. Summary of the invention
