[0020] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0021] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0022] A multifunctional overhead crane is usually installed in the electrolysis workshop to meet the special needs of the electrolysis workshop. A multifunctional overhead crane hydraulic station is also installed to provide power for the multifunctional overhead crane, so that the multifunctional overhead crane can perform operations such as replacing anodes, breaking shells, and slag removal. However, when the multifunctional overhead crane hydraulic station is in operation, affected by the environment or other factors, the multifunctional overhead crane hydraulic station may fail to start due to a fault, which in turn causes the multifunctional overhead crane to be unable to replace anodes or break shells, affecting its use, and it takes a long time for maintenance personnel to troubleshoot the fault. If the multifunctional overhead crane hydraulic station fails to start during the pole-changing operation, the tool mechanism of the multifunctional overhead crane will remain above the electrolytic cell, and the temperature of the electrolytic cell is high, making it difficult for maintenance personnel to perform maintenance above the electrolytic cell, and there are certain safety hazards.

[0023] To this end, an embodiment of the present application provides an emergency starting device and a hydraulic station control system for a multifunctional overhead crane hydraulic station. The emergency starting device can provide electrical energy to the electric motor of the multifunctional overhead crane hydraulic station when the multifunctional overhead crane hydraulic station fails and cannot be started, so that the multifunctional overhead crane hydraulic station can work normally, thereby ensuring the reliability of the use of the multifunctional overhead crane.

[0024] The emergency starting device and hydraulic station control system of the multifunctional overhead crane hydraulic station provided in the present application are exemplarily introduced below in conjunction with the accompanying drawings.

[0025] like Figure 1As shown, an embodiment of the present application provides a hydraulic station control system, including an emergency starting device 1 and a multifunctional overhead crane hydraulic station 2, wherein the multifunctional overhead crane hydraulic station 2 includes a multifunctional three-phase power supply 21 and a motor 22, one end of the emergency starting device 1 is connected to the three-phase power supply 21, the three-phase power supply 21 includes three live wires U, V, and W, and each live wire is connected to the emergency starting device 1, a first end of the motor 22 is connected to the other end of the three-phase power supply 21, at this time each live wire in the three-phase power supply 21 is connected to the emergency starting device 1, and a second end of the motor 22 is connected to the emergency starting device 1.

[0026] Under normal circumstances, in order to achieve the reliability of the power supply of the three-phase power supply 21 to the motor 22 and control the working state of the motor 22, in one example, Figure 2 As shown, the hydraulic station control system may further include a starting module 23, one end of the starting module 23 is connected to the three-phase power supply 21, and the other end of the starting module 23 is connected to the first end of the motor 22. When the multifunctional overhead crane hydraulic station 2 needs to work, the starting module 23 is turned on to send the electric energy of the three-phase power supply 21 to the motor 22, so that the multifunctional overhead crane hydraulic station 2 operates so that the multifunctional overhead crane can operate normally; when the multifunctional overhead crane hydraulic station 2 does not need to work, the starting module 23 is disconnected, at which time, the circuit between the three-phase power supply 21 and the motor 22 is disconnected, the motor 22 loses electric energy, and the multifunctional overhead crane hydraulic station 2 does not work.

[0027] Optionally, the starting module 23 can be a contactor, one end of the contactor is connected to the three-phase power supply 21, and the other end of the contactor is connected to the first end of the motor 22. The contactor has strong current breaking capacity, fast action, safe operation, and can be remotely controlled. It is easy to operate and avoids certain safety hazards when the operator is in close contact.

[0028] Under the above-mentioned normal circumstances, the multifunctional three-phase power supply 21 can directly provide electric energy to the motor 22, so that the motor 22 can work normally, and then the multifunctional overhead crane hydraulic station 2 can work normally, so that the multifunctional overhead crane can perform operations such as replacing anodes or shelling. However, when the multifunctional overhead crane hydraulic station 2 is in operation, affected by the environment or other factors, the multifunctional overhead crane hydraulic station 2 may have a problem of failure to start, that is, the three-phase power supply 21 cannot directly provide electric energy to the motor 22, or the starting module 23 fails and cannot be started normally, resulting in the multifunctional overhead crane hydraulic station 2 being unable to start. In order to ensure that the multifunctional overhead crane hydraulic station 2 can start normally, the emergency starting device 1 provided in the present application can transfer the electric energy of the three-phase power supply 21 to the motor 22, so that the motor 22 can work.

[0029] In one example, if Figure 3As shown, the emergency starting device 1 may include an emergency circuit 11, one end of the emergency circuit 11 is connected to the three-phase power supply 21, and the other end of the emergency circuit 11 is connected to the motor 22. The emergency circuit 11 is used to transfer the electric energy provided by the three-phase power supply 21 to the motor 22 when connected, so that the motor 22 works. In this way, when the starting module 23 fails and cannot be started normally, the emergency circuit 11 can be connected to transfer the electric energy provided by the three-phase power supply 21 to the motor 22, so that the multifunctional overhead crane hydraulic station 2 can work normally, that is, at this time, the remote control and other equipment that control the multifunctional overhead crane hydraulic station 2 work normally and have input and output points, and the emergency operation tool near the multifunctional overhead crane can be controlled by the remote control to rise, so as to take the multifunctional overhead crane away from the electrolytic cell for convenient maintenance. In addition, the problem of damage to the equipment caused by continuing to operate the multifunctional overhead crane after the multifunctional overhead crane hydraulic station 2 fails is avoided, the reliability of the equipment is improved, and at the same time, a certain degree of safety is improved.

[0030] In one example, if Figure 4 As shown, the emergency circuit 11 may include a switch module 111 and a connection module 112, one end of the switch module 111 is connected to the three-phase power supply 21, one end of the connection module 112 is connected to the other end of the switch module 111, and the other end of the connection module 112 is connected to the motor 22. In this example, when the multifunctional overhead crane hydraulic station 2 works normally, there is no need to start the emergency starting device 1, then the switch module 111 is disconnected, that is, at this time, the emergency circuit 11 is disconnected; when the multifunctional overhead crane hydraulic station 2 fails and cannot work normally, it is necessary to start the emergency starting device 1, at this time, the switch module 111 is controlled to be turned on so that the emergency circuit 11 is connected, and at this time, the connection module 112 can transfer the electric energy provided by the three-phase power supply 21 to the motor 22, so that the multifunctional overhead crane hydraulic station 2 can work normally. In this way, by controlling the on and off of the switch module 111, the on and off of the emergency circuit 11 and the control of the switch of the emergency starting device 1 can be realized, and the operation is simple.

[0031] Optionally, the switch module 111 may include a circuit breaker, one end of which is connected to the three-phase power supply 21, and the other end of which is connected to one end of the connection module 112. The circuit breaker is small in size and occupies a small area, and the on and off of the emergency circuit 11 is controlled by the circuit breaker, which has high reliability. The switch module 111 in the present application may also use other devices or circuits with on and off functions, and the present application does not make specific restrictions on this.

[0032] Optionally, the connection module 112 may include a contactor, one end of which is connected to the other end of the switch module 111, and the other end of the contactor is connected to the motor 22. The contactor has a strong current breaking capacity, quick action, safe operation, and can be remotely controlled, which is convenient to operate and avoids certain safety hazards when the operator is in close contact. The connection module 112 in this application may also use other devices or circuits with the function of connecting and transmitting electrical signals, and this application does not make specific restrictions on this.

[0033] In order to realize the control of the on and off of the switch module 111, in one example, Figure 5 As shown, the emergency circuit 11 also includes a control module 113, one end of the control module 113 is connected to the three-phase power supply 21, and the other end of the control module 113 is connected to the controlled end of the switch module 111. The control module 113 can control the on and off of the switch module 111 to control the on and off of the emergency circuit 11.

[0034] Optionally, the control module may be a control chip, a control circuit, etc., and this application does not impose any specific limitation on this.

[0035] In summary, the hydraulic station control system provided in the embodiment of the present application can connect the emergency circuit 11 when the start module 23 fails and cannot be started normally, so as to transfer the electric energy provided by the three-phase power supply 21 to the motor 22, so that the multifunctional overhead crane hydraulic station 2 can work normally, that is, at this time, the remote control and other equipment that control the multifunctional overhead crane hydraulic station 2 work normally and have input and output points, and the emergency operation tools near the multifunctional overhead crane can be controlled to rise by the remote control to take the multifunctional overhead crane away from the electrolytic cell for easy maintenance. Moreover, it avoids the problem of damage to the equipment caused by continuing to operate the multifunctional overhead crane after the multifunctional overhead crane hydraulic station 2 fails, improves the reliability of the equipment, and at the same time, improves a certain degree of safety.
