Description

Technical Field

[0001] The utility model relates to the technical field of tank container train loading and unloading, in particular to a liquid tank container unloading device. Background Art

[0002] The liquid tank container unloading valve is installed at the bottom of the tank end face, and the opening direction is perpendicular to the end face. When transporting heavy oil by liquid tank container trains, the existing train tank car side unloading solution and unloading equipment cannot be used. At present, for the unloading of the medium in the tank container, a combined unloading arm is usually used. The combined unloading arm is composed of a plurality of arm tubes that are rotatably connected to each other. The rotation between the plurality of arm tubes can adjust the distance between the two ports of the combined unloading arm to meet the distance between the tank container unloading port and the oil pipeline inlet; when in use, one port of the combined unloading arm is connected to the tank container unloading port, and the other port of the combined unloading arm is connected to the oil pipeline inlet, but this unloading method has great limitations and needs to be improved.

The utility model is provided with a supporting mechanism, and when the adjusting screw nut is rotated, the adjusting screw rod will realize the linear motion in the vertical direction, thereby driving the lower arm tube to follow the adjusting screw rod to perform the linear motion in the vertical direction, thereby playing the role of adjusting the overall height of the combined unloading arm.

[0004] However, the device still has some shortcomings: the unloading arm of the device is difficult to adjust during the extension and contraction process, and the response is slow. At the same time, the device is easily restricted by the site. During the unloading process, the unloading arm tube needs to undergo multiple sets of rotations to reach the unloading position. This action requires the linkage of multiple sets of driving parts, which is time-consuming and labor-intensive. Summary of the invention

[0022] A tank body 2 is arranged inside the support frame 1, and a discharge pipe 3 connected to the inside of the tank body 2 is arranged on the tank body 2, and the output end of the discharge pipe 3 is connected to a connecting pipe 4, and a solenoid valve A5 for switching on and off inside the controller is arranged on the connecting pipe 4.

[0023] The storage box 6 is arranged on the support frame 1, and a roller 7 connected to the storage box 6 for rotation is arranged inside the storage box 6, a driving member for driving the roller 7 to rotate is arranged inside the storage box 6, and a locking member for limiting the rotation of the roller 7 is arranged on the storage box 6. The locking member includes a clamping block 16 and a hydraulic cylinder 17, and a slide groove is symmetrically arranged inside the side plate of the storage box 6, and the slide groove is connected to the circular hole of the roller 7. The clamping block 16 is slidably arranged in the corresponding side slide groove, and the hydraulic cylinder 17 is arranged in the slide groove, and the hydraulic cylinder 17 drives the connecting clamping block 16. Elastic gaskets are arranged on the sides where the clamping blocks 16 on both sides are close to each other, and a plurality of anti-slip teeth are arranged on the elastic gaskets. The external pipe 10 is wound around the roller 7 and communicated with the inside thereof, and the connecting pipe 4 is inserted into the roller 7 and communicated with the external pipe 10, and the connecting pipe 4 is connected to the roller 7 for rotation. The external pipe 10 is connected to the discharge pipe 11, a wireless control handle 12 is arranged on the discharge pipe 11, a control box 102 is arranged on the support frame 1, and the wireless control handle 12 is communicatively connected with the control box 102. A plurality of card holders 101 are arranged on the support frame 1, a card slot is arranged in the card holder 101, two elastic limit blocks are symmetrically arranged in the card slot, the discharge pipe 11 is inserted into the card slot and slidably connected thereto, and the elastic limit block elastically abuts against the discharge pipe 11.
