However, most of the existing crane tubes with submersible pumps have no good sealing measures for the crane tubes with submersible pumps, because they cannot handle the sealing effect when the oil inlet and outlet pipes go down and up with the telescopic tube, when the inlet and outlet oil ports enter and exit the sealing cover Very poor phenomenon, especially for the unloading of volatile and toxic liquids, the sealing effect is particularly important, and in the prior art, it is difficult to accurately measure the liquid level during the unloading process

Abstract
The invention discloses a novel unloading crane pipe with an oil-immersed pump and belongs to the technical field of crane pipes. The novel unloading crane pipe comprises a hydraulic oil storage tank, a vane pump, a negative-pressure oil delivery pipe, a positive-pressure oil delivery pipe, a pneumatic hoist, a vertical pipe, the oil-immersed pump, a supporting frame module, a rotary arm module, a gaseous phase pipe, an oil outlet pipe, an oil inlet pipe, a sleeve, an oil outlet, a telescopic pipe and a seal cover, wherein the supporting frame module comprises a first bent pipe, an inner arm, a second bent pipe, a second rotary connector, a second pneumatic motor, an outer arm, a rotary frame, a rotary rod and a hydraulic cylinder. The novel unloading crane pipe has sealing effect during oil unloading, ensures the safety of volatile toxic liquid during unloading and avoids the phenomenon that an operator is possibly burned by acid. Positive-pressure oil unloading is adopted, so that air resistance and cavitation phenomena of the crane pipe do not exist, oil unloading speed is improved, and the liquid level in a tank truck can be accurately measured.
Description
technical field [0001] The invention belongs to the technical field of crane pipes, and more specifically relates to an unloading crane pipe with a submersible oil pump. Background technique [0002] At present, there are many types of crane pipes for unloading vehicles, but because most of the crane pipes for unloading oil are prone to air resistance and cavitation when unloading tanks in high temperature and low pressure areas, oil depots around the world have to add submerged pipes to the oil unloading system. oil pump. However, most of the existing crane tubes with submersible pumps have no good sealing measures for the crane tubes with submersible pumps, because they cannot handle the sealing effect when the oil inlet and outlet pipes go down and up with the telescopic tube, when the inlet and outlet oil ports enter and exit the sealing cover Very poor phenomenon, especially for the unloading work sealing effect of volatile and toxic liquids is particularly important, ...
