Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Fig. 1 to Fig. 5, a kind of water brake screw pump ground driving device, including motor 1, motor output shaft are logical
It crosses gear to be connected with retarder gear wheel 2, the retarder gear wheel 2 is fixed in intermediate tooth shaft 7, wherein retarder gear wheel
2 are connected with hydraulic pump driving tooth shaft 3, and intermediate tooth shaft 7 is connected with output shaft gear wheel 8, and output shaft gear wheel 8 is fixed on output
On axis 9, output shaft 9 can be driven to rotate.Wherein output shaft 9 passes through square clamp connection polished rod, and 9 top of output shaft is fixed with brake
Hull 10.3 lower end of hydraulic pump driving tooth shaft connects freewheel clutch, and freewheel clutch lower end connects hydraulic pump 5, so that liquid
Press pump be driven tooth shaft 3 can only one-way tape hydrodynamic press pump 5 work, i.e., hydraulic pump driving tooth shaft 3 rotate forward when, hydraulic pump 5 does not work, liquid
When press pump is driven the reversion of tooth shaft 3, hydraulic pump 5 starts.It is connected separately with hydraulic oil container 5 and flow divider 6 on the hydraulic pump 5,
Middle flow divider 6 is connected with hydraulic caliper 11 and hydraulic oil container 5 respectively.
The structure of the flow divider 6 be it is such, the center culvert of horizontal direction is provided in flow divider 6, in center culvert
Equipped with elastic force spool 63,63 left end of elastic force spool is equipped with valve ball 62, and 63 right end of elastic force spool is equipped with adjustment spring 65, adjusts bullet
65 right end of spring is fixed by adjusting nut 67, shunts and is corresponded on valve body equipped with positioning screw 66 at adjusting nut 67, for solid
Determine adjusting nut 67.The hydraulic pump interface 68 being connected with hydraulic pump 5 is provided in the center culvert, by fluid pressure line with it is hydraulic
Pump 5 is connected, and center culvert left end is hydraulic caliper interface 61, is connected by fluid pressure line with hydraulic caliper 11.In center culvert
The right side of valve ball 62 connects fuel tank interface 64, is connected by fluid pressure line with hydraulic oil container 4.
