Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-5, to avoid dragging the metal hose on the ground when the metal hose is connected, the metal hose is broken. The utility model provides a metal hose anti-dragging storage device for an LNG tank wagon, which comprises a winding frame 1, a winding drum 8 rotatably installed on the winding frame 1 and a metal hose 2 wound on the winding drum 8, wherein two ends of the metal hose 2 are respectively wound on two ends of the metal hose 2 in the same rotation direction, two ends of the metal hose 2 are respectively positioned above and below the winding drum 8, a limiting roller 3 for supporting the end wall of the metal hose 2 and taking a flange plate at the end part of the metal hose 2 as a limit is arranged on the inner wall of the winding frame 1, the winding drum 8 is connected with the winding frame 1 through an elastic reset structure, and a roller 5 is arranged at the bottom of the winding frame 1.

The winding frame 1 is U-shaped, the winding drum 8 is horizontally rotatably arranged in the winding frame 1, two ends of the metal hose 2 are respectively wound at two ends of the winding drum 8 and are wound in a winding mode shown in fig. 5, so that when any one end of the metal hose 2 is unreeled, the winding drum 8 can rotate in the same direction, the elastic reset structure generates corresponding winding force, and therefore the metal hose 2 is prevented from being rubbed on the ground while leaving the winding frame 1. The roller 5 adopts a common universal castor, and is also provided with a pedal brake, so that the roller 5 is locked by one pedal, and the roller 5 is unlocked by one pedal.
