[0002] In the field of oil drilling, hydraulic stations provide power to multiple hydraulically driven equipment, such as iron roughnecks, mud blowout preventers, pipe support manipulators, etc. When the hydraulic station system of the drilling rig is not equipped with an integrated control system, each hydraulically driven equipment is operated by a remote control or a local operating console. When the emergency stop button of the remote control or the local operating console is pressed, the relevant hydraulically driven equipment will stop, but the output of the hydraulic source cannot be stopped. In addition, when the solenoid valve of the hydraulically driven equipment is stuck or other problems cause the solenoid valve core to be unable to return to the center position, the delivery of the hydraulic source is not stopped. Even if the emergency stop button of the remote control or the local operating console is pressed, the hydraulically driven equipment still cannot stop moving, seriously affecting the safety of personnel and equipment. Summary of the invention

[0003] The purpose of the present invention is to provide a safe emergency stop control device, which solves the problem that the existing drilling hydraulic system cannot emergency stop and cut off the hydraulic output of the hydraulic station.

[0004] The technical solution adopted by the present invention is to include a hydraulic drive equipment system, the hydraulic drive equipment system is connected to an emergency stop control unit system via wires, the emergency stop control unit system is connected to an auxiliary unit via wires, and the auxiliary unit is connected to a hydraulic station electronic control system via wires.

[0005] The present invention is also characterized in that:

[0006] The hydraulic drive equipment system comprises a plurality of hydraulic drive equipment units, each of which is connected to an emergency stop control unit system.

[0007] The emergency stop control unit system comprises emergency stop control unit groups corresponding to the number of hydraulic drive equipment units, and each emergency stop control unit group is connected to the corresponding hydraulic drive equipment unit through a wire.

[0008] The hydraulic drive equipment unit includes a circuit breaker and an equipment output terminal block. The circuit breaker is connected to a switching power supply through a wire. The switching power supply is respectively connected to a power-on relay and an emergency stop relay through wires. The power-on relay is connected to the emergency stop relay through a wire. The emergency stop relay is connected to an equipment emergency stop button through a wire. The switching power supply, the power-on relay and the emergency stop relay are respectively connected to the equipment output terminal block through wires.

[0009] The emergency stop control unit group includes an equipment emergency stop power-on relay and an equipment input terminal block. The equipment emergency stop power-on relay is connected to an emergency stop unit emergency stop relay through a wire. The equipment emergency stop power-on relay and the emergency stop unit emergency stop relay are respectively connected to the equipment input terminal block through wires.

[0010] The auxiliary unit and the equipment input terminal block are connected through wires.

[0011] The hydraulic station electronic control system includes a hydraulic pump emergency stop relay, which is connected to the hydraulic pump emergency stop switch power supply through wires, which is connected to the hydraulic station terminal block through wires, which is connected to the hydraulic pump control relay through wires, which is connected to the hydraulic pump emergency stop relay through wires, which is connected to the hydraulic pump control relay through wires, which is connected to the hydraulic pump emergency stop relay, which is connected to the hydraulic pump motor contactor through wires, which is connected to the hydraulic pump motor and the hydraulic pump power supply terminal block through wires.

[0015] 2. This system solves the problem that the emergency stop of a single device cannot stop the hydraulic station's fluid supply: when the solenoid valve core cannot return to the center position due to problems such as solenoid valve core jamming, even if the equipment is emergency stopped and the equipment emergency stop system sends an electrical stop signal, the hydraulic source can still be supplied to the actuator through the solenoid valve, threatening the safety of operators and equipment.

[0016] 3. The system will automatically block unmatched equipment. When the equipment is not connected to the system, the system will automatically block the equipment and the hydraulic station will operate normally, solving the following problem: If all equipment emergency stop normally closed contacts are directly connected in series to the control contacts of the hydraulic station, when any equipment is not matched or one needs to be powered off for maintenance, the hydraulic station will not be able to start because the control contacts are disconnected.

[0017] 4. When adding a device to the system, add an emergency stop control unit to the new device and insert the multi-core cable of the unit's output into any group of equipment for processing. No special control contacts are required, and it has strong interchangeability and high fault tolerance.

The changes to the original equipment, hydraulic station, driller's room, etc. are relatively minor, which is convenient for production and convenient and efficient for later maintenance.

When the equipment is not equipped, the system will automatically shield the equipment, and the hydraulic station will not be caused to stop suddenly when the equipment is not connected; when the equipment is powered on and not stopped suddenly, the hydraulic station operates normally and provides hydraulic source to each equipment; when the equipment is powered on and the equipment is stopped suddenly, the hydraulic station stops running, each equipment stops providing hydraulic source, and the equipment stops, achieving the purpose of safe production.

[0030] The safety emergency stop control device provided by the present invention has a working principle that, for equipment, according to the matching conditions, power-on conditions and emergency stop conditions, there are three working conditions in total.

[0031] 1. The equipment is not matched or the equipment is matched but not powered on. In this case, the system will automatically bypass the equipment and send the no emergency stop signal to the hydraulic station according to the logic, which will not cause the emergency stop of the hydraulic station and affect other operating equipment. The specific process is as follows: the switch power supply 102 is not powered on, and the D point of the switch power supply 102 is at a low level. Therefore, A1 and A2 of the power-on relay 103 are blocked, resulting in 11 and 14 of the relay being blocked. Therefore, the power-on signal of terminal 1 of the equipment output terminal block 106 is at a low level; A1 of the equipment emergency stop relay 105 is not powered on, so 13 and 14 of the relay are disconnected, resulting in the emergency stop signal of terminal 2 of the equipment output terminal block 106 being at a low level. It can be seen at this time that in this state, terminals 1 and 2 of the equipment output terminal block 106 are both at a low level. According to the signal of the previous process, terminal 1 of the device input terminal row 203 is connected to terminal 1 of the device output terminal row 106, terminal 2 of the device input terminal row 203 is connected to terminal 2 of the device output terminal row 106, and terminal 3 of the device input terminal row 203 is connected to terminal 3 of the device output terminal row 106. At this time, terminal 1 is at a low level, and contacts 13 and 12 of the device emergency stop power-on relay 201 are connected; terminal 2 of the device input terminal row 203 is at a low level, and contacts 11 and 14 of the relay are disconnected. The signal of terminal 4 of the device input terminal row 203 is directly connected to terminal 5 of the device input terminal row 203 through contacts 13 and 12 of the device emergency stop power-on relay 201, and is in the on state. At this time, terminals 1A and 1B of auxiliary unit 3 are in the on state. If m similar devices are equipped, then An and Bn are both in the on state, and the auxiliary power supply terminals A and B are also in the on state. In this case, the emergency stop signal sent to the emergency stop control unit 4-9 of the hydraulic station is turned on, and no emergency stop is performed at this time.

[0032] 2. The equipment has been assembled and powered on, and has not been emergency stopped. At this time, the equipment is working normally and the hydraulic station is not emergency stopped. The specific process is as follows: the switching power supply 102 is powered on, and point D of the switching power supply 102 is at a high level. Therefore, A1 and A2 of the power-on relay 103 are turned on, causing 11 and 14 of the relay to be turned on, and the high-level signal from point D passes through the 11 and 14 contacts of the power-on relay 103 to reach terminal 1 of the equipment output terminal block 106. At this time, the power-on signal is high level; A1 of the equipment emergency stop relay 105 is energized. After power-on, the equipment emergency stop button 104 is not pressed, and the 11 and 12 contacts of the equipment emergency stop button 104 are turned on. The control contacts S11 and S12 of the equipment emergency stop relay 105 are turned on. At this time, 13 and 14 of the equipment emergency stop relay 105 are turned on, and the high-level signal from point D passes through the 11 and 14 contacts of the power-on relay 103 and the 13 and 14 contacts of the equipment emergency stop relay 105 to reach terminal 2. At this time, the emergency stop signal is high level. At this time, it can be seen that in this state, both the No. 1 and No. 2 terminals of the device output terminal row 106 are at high level. According to the signal of the previous process, the No. 1 terminal of the device input terminal row 203 is connected to the No. 1 terminal of the device output terminal row 106, the No. 2 terminal of the device input terminal row 203 is connected to the No. 2 terminal of the device output terminal row 106, and the No. 3 terminal of the device input terminal row 203 is connected to the No. 3 terminal of the device output terminal row 106. The No. 1 terminal of the device input terminal row 203 is at a high level, at which time the 13 and 12 contacts of the device emergency stop power-on relay 201 are disconnected, and the 11 and 14 contacts are turned on; the No. 2 terminal of the device input terminal row 203 is at a high level, at which time the No. 11 and 14 contacts of the relay are turned on. The signal of terminal 4 of the equipment input terminal row 203 passes through the 11th and 14th contacts of the equipment emergency stop power-on relay 201, and then passes through the 11th and 14th contacts of the emergency stop unit emergency stop relay 202 and the 5th terminal of the equipment input terminal row 203, which is in the on state. At this time, the 1A terminal and the 1B terminal of the auxiliary unit 3 are in the on state. If m similar devices are equipped, then An and Bn are both in the on state, and at this time, the auxiliary power supply terminals A and B are also in the on state. In this case, the emergency stop signal sent to the emergency stop control unit 4-9 of the hydraulic station is on, and there is no emergency stop at this time.

[0033] 3. The equipment has been powered on and has been emergency stopped. At this time, the hydraulic station stops running and the equipment stops moving. The switching power supply 102 is powered on, and point D of the switching power supply 102 is at a high level. Therefore, A1 and A2 of the power-on relay 103 are turned on, causing 11 and 14 of the relay to be turned on. The high-level signal from point D passes through contacts 11 and 14 of the power-on relay 103 to reach terminal 1 of the device output terminal block 106. At this time, the power-on signal is at a high level; A1 of the device emergency stop relay 105 is energized. After power-on, the device emergency stop button 104 is pressed, and contacts 11 and 12 of the device emergency stop button 104 are disconnected. Control contacts S11 and S12 of the device emergency stop relay 105 are disconnected. At this time, contacts 13 and 14 of the device emergency stop relay 105 are disconnected. The high-level signal from point D passes through contacts 11 and 14 of the power-on relay 103. Since contacts 13 and 14 of the device emergency stop relay 105 are disconnected, the high-level signal cannot reach terminal 2. At this time, the emergency stop signal is at a low level. At this time, it can be seen that in this state, terminal 2 of the device output terminal row 106 is at a low level and terminal 1 is at a high level. According to the signal of the previous process, terminal 1 of the device input terminal row 203 is connected to terminal 1 of the device output terminal row 106, terminal 2 of the device input terminal row 203 is connected to terminal 2 of the device output terminal row 106, and terminal 3 of the device input terminal row 203 is connected to terminal 3 of the output terminal row 106. Terminal 1 of the device input terminal row 203 is at a high level, at which time contacts 13 and 12 of the device emergency stop power-on relay 201 are disconnected, and contacts 11 and 14 are connected; terminal 2 of the device input terminal row 203 is at a low level, at which time contacts 11 and 14 of the relay are disconnected. The signal of terminal 4 of the equipment input terminal row 203 passes through the 11th and 14th contacts of the equipment emergency stop power-on relay 201. Since the 11th and 14th contacts of the emergency stop unit emergency stop relay 202 are disconnected, the signal of terminal 5 of the equipment input terminal row 203 cannot be connected. At this time, the A1 and B1 terminals of the auxiliary unit 3 are in the disconnected state. In this case, the emergency stop signal sent to the hydraulic station electronic control system 4 is in the disconnected state, and the emergency stop is performed.
