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...

Embodiment Construction

[0027] Such as Figure 1 to Figure 5 As shown, the present embodiment provides a tank container train loading and unloading arm, including a support mechanism, a lower arm tube 15, an inner arm tube 3, a middle arm tube 5, an outer arm tube 6, a metal hose 7, an upper arm tube 8 and a fast Parts such as joint 9.

[0028] The supporting mechanism is arranged on one side of the train track, and the lower arm pipe 15 is fixedly connected to the supporting mechanism. One end of the lower arm pipe 15 extends horizontally, and one end of the lower arm pipe 15 is provided with a pipe joint (flange 13 in this embodiment) One end of the lower arm pipe 15 can be connected to the oil pipeline through the flange 13, and the other end of the lower arm pipe 15 is bent upward to form a 90° elbow to connect with the inner arm pipe 3.

[0029] In this embodiment, the support mechanism is a supporting column 1, the bottom of which is fixed on the ground through an assembly plate 16, and a lowe...
