Cantilever type automatic aligning oil-unloading crane tube

Abstract

The invention relate to train tank car liquid loading and unloading equipment, in particular to a cantilever type automatic aligning oil-unloading crane tube. The upper-end pipe orifice of a first connecting pipe is in stationary sealing communication with the lower-end pipe orifice of a second connecting pipe, any two adjacent third connecting pipes in an articulated pipe set are in dynamic sealing communication, the upper-end pipe orifice of the first section of third connecting pipe in the articulated pipe set communicates with a fourth connecting pipe, the lower-end pipe orifice of a horizontal rotating pipe is in dynamic sealing communication with the upper-end pipe orifice of a fourth connecting pipe, the lower-end pipe orifice of a lower arc segment-shaped connecting pipe is in dynamic sealing communication with the upper-end pipe orifice of the horizontal rotating pipe, the upper-end pipe orifice of an upper arc segment-shaped connecting pipe is in dynamic sealing communicationwith the upper-end pipe orifice of a second vertical rotating pipe, the lower-end pipe orifice of the second vertical rotating pipe is in stationary sealing communication with the upper-end pipe orifice of a vertical hanging pipe, the lower-end pipe orifice of the hanging pipe fixedly hangs an immersed pump and is in stationary sealing communication with a liquid outlet of the immersed pump. One-key automatic loading and unloading can be realized, and the closed loading operation can be completed.

Description

technical field [0001] The invention relates to liquid loading and unloading equipment for train tank cars, in particular to a cantilever type automatic alignment oil unloading crane pipe. Background technique [0002] Ordinary cantilever oil unloading crane mainly includes column, inner arm, spring steel balance system, outer arm, drop pipe, submersible oil pump. Ordinary cantilever oil unloading crane pipe is manually operated, and the submersible oil pump is placed on the bottom of the tank car by manually pulling the vertical pipe. The spring steel balance system is used to balance the moment generated by the outer arm, vertical pipe and submersible pump to ensure manual operation; the submersible pump is used to unload oil. Some problems of ordinary cantilever crane tubes: 1. High labor intensity. During the loading process, the operator needs to pull the crane pipes one by one, put the drop pipe into the tank car, and the train trestle is usually about 200 meters, an...
