BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 The utility model discloses an embodiment related to the structure diagram of hydraulic station.

[0012] The figure sign is: 1, working oil pump, 2, first clutch, 3, double output shaft motor, 4, second clutch, 5, standby oil pump, 6, first input, 7, first output shaft, 8, second output shaft, 9, second input. DETAILED DESCRIPTION

[0013] The utility model discloses an embodiment related to the structure diagram of hydraulic station.

[0014] The utility model provides a kind of hydraulic station with quick switching of standby oil pumps, as shown in Figure 1 Figure, including double output shaft motor 3, working oil pump 1, standby oil pump 5, first clutch 2 and second clutch 4, the two ends of double output shaft motor 3 are respectively equipped with first output shaft 7 and second output shaft 8, first output shaft 7 is detachably connected with working oil pump 1 by first clutch 2, second output shaft 8 is detachably connected with the standby oil pump 5 by second clutch 4, and the shape of first output shaft 7 is engaged with the shape of the first clutch 2, the shape of second output shaft 8 is engaged with the shape of the second clutch 4. When working, first clutch 2 is closed, working oil pump 1 is connected into double output shaft motor 3, and second clutch 4 is disconnected;When working oil pump is damaged, second clutch 4 is closed, first clutch 2 is disconnected after standby oil pump 5 is connected into double output shaft motor 3.

[0015] More specifically, working oil pump 1 and standby oil pump 5 are symmetrically arranged relative to double output shaft motor 3, and symmetrically arranged can better adapt to general motor.

[0016] Specifically, working oil pump 1 is provided with first input 6 at one end, and first input 6 is fixedly connected with first clutch 2, and one end of standby oil pump 5 is provided with second input 9, and second input 9 is fixedly connected with second clutch 4.

[0017] Specifically, first clutch 2 and second clutch 4 are both manual clutches, so that the operator can rotate the handle flexibly to switch the oil pump according to the actual situation.

[0018] The working process of the above-mentioned hydraulic station with quick-switching standby oil pump 5 includes the following steps:

[0019] Step 1, ensure that the first clutch 2 has connected the first input port 6 with the first output shaft 7, start the double-output shaft motor 3, at this time the double-output shaft motor 3 is connected with the working oil pump 1.

[0020] Step 2, when the working oil pump 1 fails, first open the second clutch 4, connect the second input port 9 with the second output shaft 8, connect the standby oil pump 5 with the double-output shaft motor 3, then close the first clutch 2, disconnect the first input port 6 from the second output shaft 8, and disconnect the standby oil pump 5 from the double-output shaft motor 3.
