Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See Figure 1 and Figure 2 As shown, a movable lift control console with a backup power supply includes a main circuit pump station 1, a mains connection terminal 2 connected to the main circuit pump station, and a control circuit 3 connected to the main circuit pump station. A backup power supply circuit 4 is connected in parallel to the mains connection terminal, and a conversion switch 5 (ZHK) is provided between the mains connection terminal and the main circuit pump station; a charging button switch NK is provided on the mains connection terminal. In actual application, the conversion switch is disconnected, and the mains connection terminal charges the backup power supply circuit. In this embodiment, a 24V fully intelligent pulse battery repair charger 6 connected to the backup power supply circuit is provided on the mains connection terminal. In actual application, the backup power supply circuit is a 24V rechargeable battery. Among them, the main circuit pump station is a mobile hydraulic pump station.

[0025] In this embodiment, the control circuit includes a circuit breaker 31, an ascending control circuit 32, a descending control circuit 33, a locking control circuit 34 and an unlocking electromagnet circuit 35; wherein the circuit breaker is 10A-DLQ2, when connected, the circuit breaker is connected to the conversion switch, the ascending control circuit and the descending control circuit are connected in parallel, and the input ends of the ascending control circuit and the descending control circuit are connected to the output ends of the circuit breaker, and the output ends are connected to the neutral line; the unlocking electromagnet circuit is connected in series with the locking control circuit, and the input end of the locking control circuit is connected to the circuit breaker, and the output end is connected to the neutral line. In actual application, the ascending control circuit includes a series-connected ascending normally open double button SA, an upper limit single normally closed switch SXW, a high current DC contactor JQ, and a motor thermal protection switch RB;

[0026] The descending control circuit includes a descending normally open double button XA, a synchronous single normally closed limit switch TB and a descending solenoid valve DCF connected in series;

[0027] There are two normally closed locking buttons LSA, one is connected in parallel to the descending normally open double button, and the other is connected between the unlocking electromagnets DC1, DC2 and the descending normally open double button.

[0028] In this embodiment, the control circuit further includes a power indicator light circuit 36. The power indicator light circuit 36 ​​includes an indicator light XD.

[0029] In this embodiment, the mobile hydraulic pump station includes an oil tank 11, a hydraulic pump 12 connected to the oil tank, and a motor 13 connected to the hydraulic pump. The output end of the hydraulic pump is provided with a check valve 14, a pressure regulating valve 15, and a buffer 16; a filter 17 is provided between the hydraulic pump and the oil tank; and a throttle valve 18 is provided between the output end of the check valve and the oil tank. The oil tank is an 8L oil tank, and the motor is connected to the hydraulic pump mainly for the start and stop control operation of the hydraulic pump. The check valve 14, the pressure regulating valve 15, the buffer 16, the filter 17, and the throttle valve 18 are all conventional structures of the prior art, which are simply applied, so they are not recorded in detail.

[0030] Its working principle is briefly described as follows: When in normal use, disconnect the charging button switch NK and close the circuit breaker of the main circuit, control the circuit breaker, and energize the circuit. When the rising normally open double button SA is pressed and held, the current passes through the rising normally open double button SA→upper limit single normally closed switch SXW→motor thermal protection switch RB to energize the high-current DC contactor JQ, so that the DC 24V / 2.2KW motor runs and drives the gear pump to rotate, output 25MPa high-pressure hydraulic oil, push the oil cylinder piston to make the lift rise, release the button, and the lift stops rising;

[0031] When the normally open double button XA for descending is pressed and held, the current passes through the normally open double button XA for descending → the synchronous single normally closed limit switch TB → energizes the descending solenoid valve DCF. At the same time, the current passes through the normally open double button XA for descending → the normally closed locking button LSA → energizes the unlocking electromagnets DC1 and DC2. The oil in the lift cylinder returns to the oil tank through the descending solenoid valve DCF, and the lift descends. Release the button and the lift stops descending.

[0032] When the normally closed locking button LSA is pressed and held, the current passes through the normally closed locking button LSA → synchronizes the single normally closed limit switch TB → energizes the descending solenoid valve DCF, and at the same time, the normally closed locking button LSA → de-energizes the unlocking electromagnets DC1 and DC2. The oil in the lift cylinder returns to the oil tank through the descending solenoid valve DCF, and the lift descends until the lock teeth lock and stop descending. Release the button and the locking is completed.

[0033] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a backup power supply circuit is provided and cooperates with a conversion switch. When the conversion switch is disconnected, it can not only charge the backup power supply circuit, but also when the city power is cut off, the backup power supply can be supplied, thereby ensuring the stability and reliability of subsequent operations, which is conducive to ensuring emergency maintenance of vehicles, and is stable and reliable to use, with strong applicability and good practicality.

At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
