Description

Technical Field

[0001] The utility model belongs to the technical field of railway transportation, and in particular relates to a stress-induced automatic separation device for a water pipe on a train. Background Art

[0002] Train refers to a train with a locomotive and specified train signs. EMU trains are self-propelled fixed trains. Single locomotives, large track maintenance machinery and heavy rail vehicles should also be handled as trains even if they do not fully meet the conditions of a train.

[0003] The existing technology has the following problems: there are many water supply stations during the operation of existing trains. If any of the water supply workers, integrated controllers, and passenger service officers do not strictly follow the operating standards and forget to pull out the pipe or press the button (intelligent pipe disconnection) during the operation, it will cause personal and driving safety hazards and risks when pulling the pipe to start the train. Automatic disconnection cannot be achieved based on the existing water supply equipment. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a device for automatically detaching a water pipe under stress on a train, which has the characteristic that the water pipe can automatically fall off when the water pipe is under stress.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for automatically disengaging a water pipe on a train under force, comprising a water inlet hose, a steering tube being provided at one end of the water inlet hose, a telescopic hose being provided at the other end of the steering tube, a disconnecting pipe being provided at the other end of the telescopic hose, a water inlet pipe being provided on one side of the disconnecting pipe, an annular plate being provided on one side of the surface of the water inlet pipe, a fixed pipe being provided at one end of the water inlet pipe away from the annular plate, and a plug-in tube being provided inside the fixed pipe.

[0006] Preferably, connecting rings are provided at both ends of the annular plate, a spring is provided at one end of the connecting ring, a hook is provided at the other end of the spring, two fixing ears are provided at both ends of the disjointed tube, a connecting rod is provided between the two fixing ears, a fixing ring is provided at one end of the connecting rod, and notches are provided at positions corresponding to the fixing ears at both ends of the fixed tube.

[0007] Preferably, the annular plate and the water inlet pipe are welded into an integral structure, and the fixed pipe and the water inlet pipe as well as the fixed ear and the disconnected pipe are spot welded.

[0008] Preferably, the connecting rod and the fixing ear are connected via damping rotation, and through holes corresponding to the connecting ring and the fixing ring are respectively provided in the connecting rod and the annular plate.

[0009] Preferably, after the disjoint pipe enters the fixed pipe, the side of the disjoint pipe is in close contact with the inner wall of the fixed pipe, and after the plug-in pipe enters the disjoint pipe, the side of the plug-in pipe is in close contact with the inner wall of the disjoint pipe.

[0010] Preferably, the connecting rod and the fixing ear are connected via damping rotation, and through holes corresponding to the connecting ring and the fixing ring are respectively provided in the connecting rod and the annular plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model sets a disconnect pipe, and the end of the water inlet pipe away from the fixed pipe is connected to the water pipe, the water inlet hose is connected to the water inlet of the train, and then the disconnect pipe is inserted into the fixed pipe. At the same time, the plug-in pipe in the fixed pipe enters the disconnect pipe, and the water pipe injects water into the water inlet pipe. Water enters the train through the water inlet pipe, the fixed pipe, the steering pipe and the water inlet hose. When the train forgets to unplug the water inlet hose during running, the train pulls the plug-in pipe to separate it from the disconnect pipe, so as to achieve the effect of automatic detachment of the water pipe, thereby avoiding the safety hazards and risk escalation of the train running with water pipes.

[0013] 2. The utility model sets a spring. When the plug-in tube and the disconnecting tube are connected, the connecting rods at both ends of the disconnecting tube enter the notch of the fixed tube, and the connecting rod is moved to a vertical state. Then the spring is pulled to make the hook at one end of the spring enter the fixed ring at one end of the connecting rod, so that the disconnecting tube and the plug-in tube are more firmly connected. When the train is running, the spring stretches the connecting rod to rotate on the fixed ear. During the rotation of the connecting rod, the hook separates from the fixed ring, and the disconnecting tube is separated from the plug-in tube. By setting the spring and the fixed ring, the disconnecting tube and the plug-in tube are more firmly connected. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] By adopting the above technical solution, when the plug-in tube 12 is docked with the disconnecting tube 4, the connecting rods 13 at both ends of the disconnecting tube 4 enter the notch 15 of the fixed tube 5, and the connecting rod 13 is moved to a vertical state, and then the spring 8 is pulled to make the hook 9 at one end of the spring 8 enter the fixing ring 14 at one end of the connecting rod 13, so that the disconnecting tube 4 and the plug-in tube 12 are more firmly connected. When the train is running, the spring 8 stretches the connecting rod 13 to rotate on the fixing ear 11. During the rotation of the connecting rod 13, the hook 9 is separated from the fixing ring 14, and the disconnecting tube 4 is separated from the plug-in tube 12. By setting the spring 8 and the fixing ring 14, the disconnecting tube 4 and the plug-in tube 12 are more firmly connected.

[0022] Specifically, the annular plate 10 and the water inlet pipe 6 are welded into an integrated structure, and the fixed pipe 5 and the water inlet pipe 6 as well as the fixed ear 11 and the disconnected pipe 4 are all welded by spot welding.

[0023] By adopting the above technical solution, the annular plate 10 and the water inlet pipe 6 are welded into an integrated structure, which is more solid. Spot welding makes the fixed pipe 5 and the water inlet pipe 6 and the fixed ear 11 and the disconnected pipe 4 more solid.

[0026] Specifically, after the disjoint pipe 4 enters the fixed pipe 5 , the side of the disjoint pipe 4 is in close contact with the inner wall of the fixed pipe 5 , and after the plug-in pipe 12 enters the disjoint pipe 4 , the side of the plug-in pipe 12 is in close contact with the inner wall of the disjoint pipe 4 .

When the water inlet hose 1 is forgotten to be unplugged when the train is running, the train pulls the plug-in pipe 12 to separate from the disconnecting pipe 4, so as to achieve the effect of automatic detachment of the water pipe, and avoid the train driving with the water pipe Safety hazards and risks are upgraded. By setting the spring 8, when the plug-in tube 12 is docked with the disconnected tube 4, the connecting rods 13 at both ends of the disconnected tube 4 enter the notch 15 of the fixed tube 5, and the connecting rod 13 is moved to a vertical state. Then, the spring 8 is pulled to make the hook 9 at one end of the spring 8 enter the fixed ring 14 at one end of the connecting rod 13, so that the disconnected tube 4 and the plug-in tube 12 are more firmly connected. When the train is running, the spring 8 stretches the connecting rod 13 to rotate on the fixed ear 11. During the rotation of the connecting rod 13, the hook 9 is separated from the fixed ring 14, and the disconnected tube 4 is separated from the plug-in tube 12. By setting the spring 8 and the fixed ring 14, the disconnected tube 4 and the plug-in tube 12 are more firmly connected.
