In order to achieve the above purpose, the present utility model provides the following technical solutions: a safe power supply circuit of a mobile cab comprises a crane power supply, a UPS uninterrupted power supply and the mobile cab; the power supply main loop of the crane power supply is provided with a total breaker and a total contactor, and a power supply of a moving mechanism of the moving cab takes electricity from the front of the total breaker; the UPS uninterrupted power supply provides a standby power supply for a moving mechanism of the mobile cab.
Preferably, a relay is also connected in series between the crane power supply and the main breaker, and a normally closed contact of the relay is connected in series in a power supply circuit of the UPS and a moving mechanism of the mobile cab.
Preferably, the UPS uninterrupted power source is located in a mobile cab.
Compared with the prior art, the utility model has the beneficial effects that: the movable cab gets power from the front end of the total breaker, and after the total contactor of the crane is abnormally powered off or the total breaker is abnormally tripped, the power supply of the movable cab is not affected; and the UPS uninterrupted power supply is arranged in the mobile cab to provide a standby power supply for the mobile cab, when the power is off, the normally closed contact of the relay is closed, the UPS uninterrupted power supply supplies power to the mobile cab, and under abnormal conditions, a driver operates the mobile cab to a specific position and then safely leaves the crane, so that the safety of the driver is ensured.
Drawings
FIG. 1 is a schematic diagram of the present utility model.
In the figure: 1 crane power supply, 2 relays, 3 total circuit breakers, 4 total contactors, 5 mobile cabs, 6 UPS uninterrupted power sources and 7 normally closed contacts.
Detailed Description
The present utility model will be explained in detail by the following examples, and the purpose of the present utility model is to protect all technical improvements within the scope of the present utility model, and in the description of the present utility model, it should be understood that if there is an orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", etc., only correspond to the drawings of the present utility model, and in order to facilitate description of the present utility model, it is not necessary to indicate or imply that the apparatus or element referred to has a specific orientation.
Referring to fig. 1, the present utility model provides a technical solution: a safe power supply circuit of a mobile cab comprises a crane power supply 1, a UPS uninterrupted power supply 6 and the mobile cab 5; the main power supply circuit of the crane power supply 1 is provided with a total breaker 3 and a total contactor 4, and a power supply of a moving mechanism of the moving cab 5 takes power from the front of the total breaker 3; the UPS uninterrupted power supply 6 provides a standby power supply for a moving mechanism of the moving cab 5;
the power supply of the mobile cab 5 is taken from the front of the total breaker 3, so that the mobile cab 5 still has the power supply after the total breaker 3 and the total contactor 4 are abnormally disconnected, a driver can operate the mobile cab 5 to a specific position to leave the crane, meanwhile, the UPS uninterrupted power supply 6 is arranged in the mobile cab, the mobile cab 5 can be temporarily powered after power failure, the driver can leave the crane after the crane is powered off, and therefore, whether the total breaker 3 and the total contactor 4 are abnormally disconnected or the crane is powered off, the driver can be ensured to leave the crane safely, and the safety of the driver is ensured;
further, a relay 2 is also connected in series between the crane power supply 1 and the main breaker 3, a normally closed contact 7 of the relay 2 is connected in series in a power supply circuit of a moving mechanism of the UPS uninterrupted power supply 6 and the moving cab 5, when the relay 2 is powered off after power failure, the normally closed contact 7 is closed, namely the UPS uninterrupted power supply 6 immediately supplies power to the moving cab 5 after power failure;
in addition, a UPS 6 is located within the mobile cab 5.
