Specific implementation mode
Below in conjunction with the accompanying drawings and the utility model is described in detail in specific implementation mode.
The utility model provides a kind of Portable manual hydraulic pressure spanner, as shown in Figure 1, include shell 1, shell 1 it is upper
Side is rotatably connected to rocking arm 2, and hydraulic cylinder 3, hydraulic motor 4 and fuel reserve tank 5 are fixed in shell 1, and the piston rod of hydraulic cylinder 3 stretches out
It is rotatablely connected outside shell 1 and with rocking arm 2, the sleeve for stretching out in 1 side of shell is coaxially connected on the output shaft of hydraulic motor 4
Interface 6 is communicated with flowline 7 between hydraulic motor 4 and hydraulic cylinder 3, be provided with delivery valve 8 in flowline 7, hydraulic motor 4 with
Oil return pipe 9 is communicated between fuel reserve tank 5, fuel reserve tank 5 is also connected to by pipeline with hydraulic cylinder 3, the company of fuel reserve tank 5 and hydraulic cylinder 3
Check valve 10 and safety valve 11 are provided in take over road.
As shown in Figures 2 and 3, planetary gear mechanism can be also connected between the output shaft of hydraulic motor 4 and sleeve interface 6,
Planetary gear mechanism includes gear ring 12, and one end of the outside opposing hydraulic motor 4 of gear ring 12 is connected with sleeve interface 6, gear ring
Sun gear 13 is coaxially arranged in 12, sun gear 13 can be fixedly connected with the output shaft of hydraulic motor 4, gear ring 12 and sun gear 13
Between uniform intervals be engaged with several planetary gears 14, the center of planetary gear 14 is connected with pinion frame 15 jointly.
In use, pushing the piston of hydraulic cylinder 3 to do straight reciprocating motion by wanting rocking arm 2 to pump, on piston
