Description

Technical Field

[0001] The utility model relates to a train sewage discharge gun head, in particular to a train sewage discharge gun head breaking structure. Background Art

[0002] When a train enters a station to carry out sewage suction operations, the train stops for a limited time. After the sewage suction operation is completed, the remaining operation time is often limited, which makes it impossible for workers to remove the sewage discharge gun head in time. Therefore, when the train moves, the sewage discharge gun head is still connected to the sewage outlet of the train. This will cause the sewage discharge gun head and the sewage discharge pipe to move synchronously when the train is running, which will cause the sewage discharge pipe to break. The train will bring safety hazards when driving with a broken sewage discharge pipe, thus affecting driving safety. Utility Model Content

[0003] In order to solve the problems in the related technology, the present application provides a train sewage discharge gun head breaking structure, which solves the problem that the sewage discharge gun head is not removed in time, resulting in the sewage discharge pipe being dragged after the train is running, thereby affecting driving safety.

[0004] The technical solution is as follows:

[0005] The train sewage discharge gun head breaking structure includes a sewage discharge gun head body, one end of the sewage discharge gun head body is used to be connected to the train sewage outlet, and the other end of the sewage discharge gun head body is used to be connected to the pipeline of the sewage discharge equipment; its characteristic is that there is a breaking groove on the sewage discharge gun head body, and the strength of the section of the sewage discharge gun head body corresponding to the breaking groove is less than the strength of other positions of the sewage discharge gun head body.

[0006] Through the above technical scheme, by setting a breaking groove on the sewage gun head body, even if the workers do not have time to remove the sewage gun head body, after the train starts, as the pulling force of the train on the sewage gun head body continues to increase, when the pulling force exceeds 50KG-70KG, because the strength of the sewage gun head body where the breaking groove is set is lower than the strength of other parts of the sewage gun head body, the sewage gun head body will first break at the breaking groove, and then complete the separation of the train and the sewage gun head body, thereby avoiding the sewage pipe being damaged after the train drags the sewage equipment pipe together, thereby ensuring the safety of train driving.

[0007] Preferably, the thickness from the bottom of the fracture groove to the inner peripheral surface of the sewage discharge gun head body is 0.4mm-0.7mm.

[0008] Preferably, the sewage discharge gun head body includes a quick connector and a pagoda connector; one end of the quick connector is used to connect to the sewage outlet of the train, and the other end of the quick connector has a connector, and the connector and the pagoda connector are both reducers, and the connector and the pagoda connector both include a first end and a second end that are concentrically arranged, the diameter of the first end is larger than the diameter of the second end, and the outer wall surfaces of the first end and the second end are both provided with threads;

[0009] The first end of the connector is connected to the other end of the quick connector, the second end of the connector is connected to a control valve, the other end of the control valve is connected to the first end of the pagoda connector, and the second end of the pagoda connector is used to be connected to the pipeline of the sewage discharge equipment.

[0010] Preferably, the fracture groove is arranged at the outer periphery of the connection between the first end and the second end in the connector.

[0011] Through the above technical solution, by setting a breaking groove on the outer periphery of the connection between the first end and the second end, when there is no time to remove the sewage discharge gun head body from the sewage outlet of the train, after the train starts, as the pulling force of the train on the quick connector continues to increase, when the pulling force exceeds 50KG-70KG, the breaking groove in the connector breaks first, which makes the quick connector and the control valve lose connection, and then completes the separation of the train and the sewage pipe, thereby ensuring driving safety.

[0012] Preferably, the fracture groove is arranged at the outer periphery of the connection between the first end and the second end of the pagoda joint.

[0013] Through the above technical solution, by setting a breaking groove on the outer peripheral surface of the pagoda joint, when there is no time to remove the sewage gun head body from the sewage outlet of the train, after the train starts, as the pulling force of the train on the pagoda joint continues to increase, when the pulling force exceeds 50KG-70KG, the breaking groove in the pagoda joint will break first, which makes the pagoda joint and the control valve lose connection, and then completes the separation of the train and the sewage pipe, thereby ensuring driving safety.

[0014] Preferably, the fracture groove comprises a first fracture groove respectively arranged at the outer periphery of the connection between the first end and the second end in the connector and a second fracture groove respectively arranged at the connection between the first end and the second end in the pagoda joint.

[0015] Through the above technical scheme, by respectively setting the breaking grooves on the outer periphery of the connection between the first end and the second end and the outer periphery of the pagoda joint, when there is no time to remove the sewage discharge gun head body from the sewage outlet of the train, after the train starts, as the pulling force of the train on the sewage discharge gun head body continues to increase, when the pulling force exceeds 50KG-70KG, the breaking grooves set in the connecting head and the pagoda joint will break, which makes the quick connector and the control valve lose connection, and the control valve and the pagoda joint lose connection, thereby completing the separation of the train and the sewage pipe, thereby ensuring driving safety.

[0016] Preferably, when the connector is a nylon connector or a plastic connector, the thickness from the bottom of the fracture groove to the inner circumference of the connector is 0.5 mm-0.7 mm.

[0017] Preferably, when the connector is a steel connector, the thickness from the bottom of the fracture groove to the inner circumference of the connector is 0.3 mm-0.5 mm.

[0018] Preferably, when the connector is a copper connector or an aluminum connector, the thickness from the bottom of the fracture groove to the inner circumference of the connector is 0.4 mm-0.6 mm.

[0019] In summary, the beneficial effects of the train sewage discharge gun head breaking structure are:

[0020] 1. By setting a fracture groove on the sewage lance body, even if the workers do not have time to remove the sewage lance body, after the train starts, as the pulling force of the train on the sewage lance body continues to increase, when the pulling force exceeds 50KG-70KG, the sewage lance body where the fracture groove is set is weaker than other parts of the sewage lance body, so the sewage lance body will first break at the fracture groove, and then complete the separation of the train and the sewage lance body, thereby avoiding the sewage pipeline being damaged after the train drags the sewage equipment pipeline together, thereby ensuring the safety of train driving;

[0021] 2. By setting a fracture groove on the outer periphery of the connection between the first end and the second end, when there is no time to remove the sewage discharge gun head body from the train sewage outlet, after the train starts, as the pulling force of the train on the quick connector continues to increase, when the pulling force exceeds 50KG-70KG, the fracture groove in the connector will break first, which makes the quick connector and the control valve lose connection, and then completes the separation of the train and the sewage discharge pipe, thereby ensuring driving safety;

[0022] 3. By setting a fracture groove on the outer peripheral surface of the pagoda joint, when there is no time to remove the sewage discharge gun head from the train sewage outlet, after the train starts, as the pulling force of the train on the pagoda joint continues to increase, when the pulling force exceeds 50KG-70KG, the fracture groove in the pagoda joint will break first, which makes the pagoda joint and the control valve lose connection, and then completes the separation of the train and the sewage discharge pipe, so as to ensure driving safety;

[0023] 4. By respectively setting breaking grooves on the outer periphery of the connection between the first end and the second end and the outer periphery of the pagoda joint, when there is no time to remove the sewage discharge gun head body from the sewage outlet of the train, after the train starts, as the pulling force of the train on the sewage discharge gun head body continues to increase, when the pulling force exceeds 50KG-70KG, the breaking grooves set in the connecting head and the pagoda joint will break, which makes the quick connector and the control valve lose connection, and the control valve and the pagoda joint lose connection, thereby completing the separation of the train and the sewage pipe, thereby ensuring driving safety.

Even if the workers do not have time to remove the sewage gun head body, after the train starts, as the pulling force of the train on the sewage gun head body continues to increase, when the pulling force exceeds 50KG-70KG, because the strength of the sewage gun head body at the fracture groove 5 is lower than that of other places of the sewage gun head body, the sewage gun head body will first break at the fracture groove 5, and then complete the separation of the train and the sewage gun head body, thereby avoiding the damage of the sewage pipe after the train drags the pipeline of the sewage equipment together, thereby ensuring the safety of the train driving.

[0036] The sewage discharge gun head body includes a quick connector 1 and a pagoda connector 3; one end of the quick connector 1 is used to connect to the sewage outlet of the train, and the other end of the quick connector 1 is provided with a connector 4, and the connector 4 and the pagoda connector 3 are both reducers, and the connector 4 and the pagoda connector 3 both include a first end and a second end that are concentrically arranged, the diameter of the first end is larger than the diameter of the second end, and the outer wall surfaces of the first end and the second end are both provided with threads;

[0047] Even if the workers do not have time to remove the sewage gun head body, after the train starts, as the pulling force of the train on the sewage gun head body continues to increase, when the pulling force exceeds 50KG-70KG, the sewage gun head body will first break at the breaking groove 5 because the strength of the part of the sewage gun head body with the breaking groove 5 is lower than the strength of other parts of the sewage gun head body, and then complete the separation of the train and the sewage gun head body, thereby avoiding the sewage pipe being damaged when the train drags the sewage equipment pipe together after running, thereby ensuring the safety of the train running.

[0051] By respectively setting the breaking groove 5 at the outer periphery of the connection between the first end and the second end and the outer periphery of the pagoda joint 3, when there is no time to remove the sewage discharge gun head body from the train sewage outlet, after the train starts, as the pulling force of the train on the sewage discharge gun head body continues to increase, when the pulling force exceeds 50KG-70KG, the breaking groove 5 set in the connecting head 4 and the pagoda joint 3 will break, which makes the quick connector 1 and the control valve 2 lose connection, and the control valve 2 and the pagoda joint 3 lose connection, thereby completing the separation of the train and the sewage discharge pipe, thereby ensuring driving safety.

When the pulling force exceeds 50KG-70KG, the breaking groove 5 set on the sewage discharge gun head body will break, and then the sewage discharge gun head body and the pipeline of the sewage discharge equipment will be separated, thereby ensuring the safety of the train travel.
