Tank container train loading and unloading arm

Abstract

The invention provides a tank container train loading and unloading arm, and belongs to the technical field of tank container train loading and unloading equipment. The tank container train loading and unloading arm comprises a supporting mechanism, a lower arm tube, an inner arm tube, a middle arm tube, an outer arm tube, a hose, an upper arm tube, a quick joint and other parts. The tank container train loading and unloading arm has the beneficial effects that the bottom unloading of the end surface of a tank container train is realized under the condition that the train is not unlocked, thedesign of each arm tube meets the requirement that the dead point and cecum phenomenon is required not occur on a conveying pipeline when the heavy-mass oil such as fuel oil is loaded and unloaded, noliquid bag exists in the flowing direction of a medium in the whole process, and the oil discharging efficiency and the safety and reliability are greatly improved; and the upper arm tube, the metalhose, the outer arm tube, the middle arm tube, the inner arm tube, the lower arm tube, the rotary joint and the like cooperate in a collaborative mode so that the connecting port plane of the quick joint can be kept parallel to the connecting port plane of a liquid discharging port, and then the quick joint and the liquid discharging port can be smoothly, accurately and hermetically connected.

Description

technical field [0001] The invention relates to the technical field of tank container train loading and unloading equipment, in particular to a tank container train loading and unloading arm. Background technique [0002] In order to reduce the cost of fuel oil train transportation, the train transportation of fuel oil is gradually replaced by tank containers by existing train tank cars. Liquid tank container transportation, compared with train tank car transportation, greatly reduces the cost, which is the development direction of railway liquid transportation. The liquid tank type container unloading valve is installed at the bottom of the end face of the tank body, the pipe diameter is generally Dn80, and the opening direction is perpendicular to the end face. When transporting heavy oil by liquid tank container trains, the existing scheme and oil unloading equipment for side unloading of train tank cars cannot be used. Currently known liquid tank container train unload...

AI Technical Summary

Problems solved by technology

The liquid discharge port of the tank container is on the end face of the tank container, right above the train connecting hook, and the operator drags and lifts the Dn80 elastic hose, which makes it difficult to move smoothly and stably from the ground to the top of the train hook and connect the liquid discharge port , prone to operational safety issues such as pipeline slipping off

[0005] Second, even if a Dn80 metal hose is used to connect to the discharge port on the end surface, the hose needs a certain turning radius and takes up a large space

However, the space at the hooks of the two carriages is small. When the two carriages are unloaded at the same time, the tank containers on the two trains need to be connected with hoses, which makes it difficult to connect to the unloading port normally. Operators have no safe standing and working space, making it difficult to operate safely

[0006] The third is that currently known land-use liquid loading and unloading arms lack loading and unloading equipment for liquid tank container unloading, and it is impossible for the liquid in the tank container to flow by gravity along the loading and unloading arm to the pump inlet manifold. bag

If one unloading pump is installed for each tank container as in the case of truck unloading, for a tank container train with a train of generally 50 cars, it cannot be realized in terms of the installation site and operability of the unloading pump.
