Description

Technical Field

[0001] This utility model relates to the technical field of interlocking system for control circuit of gate and barrier at oil unloading station, and particularly to interlocking system for control circuit of gate and barrier at oil unloading station. Background Technology

[0002] An oil unloading station is located in a densely populated residential area with frequent pedestrian and animal traffic. The original safety measures for monitoring pedestrians entering the tracks relied solely on the barrier gate and on-site reminders from staff. There is a curve 100 meters from the station's main gate, creating a blind spot for drivers, passengers, and pedestrians. The existing monitoring technology was insufficient to effectively alert pedestrians and remained a potential hazard.

[0003] The existing technical measures to prevent vehicles and pedestrians from forcibly entering railway crossings when the gates are closed are currently limited to: 1. warning lights; 2. manual operation; and 3. a signal that automatically activates the gate control circuit when a train approaches a set distance from the gate, thus warning pedestrians or vehicles of the prohibition. These methods are insufficient to completely prevent pedestrians from forcibly entering unattended crossings, and many deaths occur each year due to people attempting to force their way through railway crossings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an interlocking system for the control circuit of the unloading station gate and the barrier gate. When a vehicle is passing through, the on-duty personnel close the barrier gate's horizontal bar, and the electric gate cannot be opened due to the electrical interlocking unit, effectively preventing pedestrians or vehicles from entering the barrier gate area.

[0005] This utility model provides an interlocking system for the control circuit of an oil unloading station gate and barrier gate, including a signal acquisition unit and an electrical interlocking unit. The signal acquisition unit includes a limit switch and a barrier gate bar.

[0006] The electrical interlocking unit includes a gate control circuit and a barrier gate control circuit connected in series, and the gate control circuit is connected in series with the normally closed contact of the limit switch.

[0007] When the barrier gate is lowered to the horizontal position, the normally closed contact of the limit switch is open, and the gate control circuit is disconnected; when the barrier gate is in the vertical position, the normally closed contact of the limit switch is closed, and the gate control circuit is connected.

[0008] Preferably, the gate control circuit includes a gate remote control unit and a gate manual unit arranged in parallel.

[0009] Preferably, the gate remote control unit is connected in series with the gate motor coil.

[0010] Preferably, the manual unit includes a gate start manual button and a gate intermediate relay arranged in series.

[0011] Preferably, the barrier gate control circuit includes a barrier gate remote control unit and a barrier gate manual unit arranged in parallel.

[0012] Preferably, the barrier gate remote control unit is connected in series with the barrier gate motor coil.

[0013] Preferably, the manual barrier gate unit includes a manual barrier gate start button and a barrier gate intermediate relay arranged in series.

[0014] Beneficial effects of this utility model

[0015] This utility model provides an interlocking system for the gate and control circuit of an oil unloading station. An electric gate is installed at the gate opening, and a gate arm is provided at the railway track entrance. When the gate arm is lowered to a horizontal position, one end of the gate arm contacts a limit switch, the normally closed contact of the limit switch opens, and the gate control circuit is disconnected. When the gate arm is in an upright position, one end of the gate arm disconnects from the limit switch, the normally closed contact of the limit switch closes, and the gate control circuit is connected. This utility model has a simple structure, low cost, and reliable technology. The interlocking signal from the signal acquisition unit is obtained through the contact or disconnection of the gate arm and the limit switch, realizing the acquisition of gate opening and prohibition signals. The operation procedure is intuitive and simple, and there are no malfunctions caused by complex electronic components. It can completely eliminate warning delays caused by drivers and passengers not being able to spot pedestrians in blind spots, thus preventing pedestrians and vehicles from accidentally crossing the railway tracks. This utility model enables unmanned management of railway level gates and effectively allows pedestrians and vehicles to pass through in an orderly manner according to the level gate signals, completely eliminating the phenomenon of pedestrians and vehicles forcibly breaking through the level gate.

[0020] Reference Figures 1 to 2

[0021] This utility model provides an interlocking system for the control circuit of an unloading station gate and a barrier gate, including a signal acquisition unit 1 and an electrical interlocking unit 2. The signal acquisition unit 1 includes a limit switch 3 and a barrier gate arm 4. The limit switch 3 is fixed to the end of the barrier gate arm 4 to ensure that the limit switch 3 can be reliably pressed when the barrier gate arm 4 is horizontal. The electrical interlocking unit 2 includes a gate control circuit 5 and a barrier gate control circuit 8 connected in series. The gate control circuit 5 is connected in series with the normally closed contact of the limit switch 3. When the barrier gate arm is lowered to a horizontal position, the normally closed contact of the limit switch 3 is open, and the gate control circuit 5 is disconnected. When the barrier gate arm is in an upright position, the normally closed contact of the limit switch 3 is closed, and the gate control circuit 5 is closed. The normally closed contact of the limit switch 3 is connected in series in the gate control circuit 5. When the barrier gate arm is in a horizontal position, the normally closed contact is open, the gate motor power control circuit is disconnected, and the gate cannot be operated. The unloading station's gate access is equipped with safety facilities, including a high wall surrounding the gate and an electric gate. The railway crossing also has turnstiles. However, security monitoring is not synchronized, and without effective supervision by on-duty personnel, pedestrians or vehicles may disregard safety and force their way in, leading to accidents. This utility model's electric gate, which is electrically locked, effectively prevents pedestrians or vehicles from entering the gate area.

[0022] In some embodiments, the gate control circuit 5 includes a gate remote control unit 6 and a gate manual unit 7 connected in parallel, which can open and close the gate respectively. The gate remote control unit 6 is connected in series with the gate motor coil. The manual unit includes a gate start manual button and a gate intermediate relay connected in series.

[0023] In some embodiments, the barrier gate control circuit 8 includes a barrier gate remote control unit 9 and a barrier gate manual unit 10 connected in parallel. The barrier gate remote control unit 9 is connected in series with the barrier gate motor coil. The barrier gate manual unit 10 includes a barrier gate start manual button and a barrier gate intermediate relay connected in series.

[0024] This utility model provides an interlocking system for the gate and control circuit of an oil unloading station. An electric gate is installed at the gate opening, and a gate lever 4 is provided at the railway track entrance. When the gate lever is lowered to a horizontal position, one end of the lever contacts a limit switch 3, causing the normally closed contact of the limit switch 3 to open, thus disconnecting the gate control circuit 5. When the gate lever is in an upright position, one end of the lever disconnects from the limit switch 3, causing the normally closed contact of the limit switch 3 to close, thus connecting the gate control circuit 5. This utility model has a simple structure, low cost, and reliable technology. The interlocking signal from the signal acquisition unit 1 is obtained through the contact or disconnection of the gate lever and the limit switch 3, realizing the acquisition of gate opening and prohibition signals. The operation procedure is intuitive and simple, and there are no malfunctions caused by complex electronic components. It can completely eliminate warning delays caused by drivers and passengers not being able to spot pedestrians in blind spots, thus preventing pedestrians and vehicles from accidentally crossing the railway tracks. This utility model enables unmanned management of railway level gates and effectively allows pedestrians and vehicles to pass through in an orderly manner according to the level gate signals, completely eliminating the phenomenon of pedestrians and vehicles forcibly breaking through the level gate.
