Embodiment 1
[0041] image 3 A schematic diagram of the working principle of the reversing control unit 8 in the hydraulic pressure-driven injection pump according to an embodiment of the present invention and its enlarged view are illustrated. Figure 4 A schematic diagram of the first state of the reversing control unit 8 in the hydraulic pressure-driven injection pump according to an embodiment of the present invention is illustrated. Figure 5 A schematic diagram of the second state of the reversing control unit 8 in the hydraulic pressure-driven injection pump according to an embodiment of the present invention is illustrated.
[0042] Such as Figures 3 to 5 As shown, the hydraulic pressure-driven injection pump of this embodiment includes a reversing control unit 8, and the reversing control unit 8 is used to control the piston rod 502 to switch the movement direction at the stroke end of the piston rod 502. The reversing control unit 8 includes a first trigger 803 , a second trig...
Embodiment 2
[0052] This embodiment is further improved on the basis of Embodiment 1. During the continuous operation of the pressure-driven injection pump, due to the sticking of the spool of the hydraulic valve or other reasons, there is a possibility of reversing failure.
[0053]In the hydraulic pressure-driven injection pump of this embodiment, the reversing control unit 8 further includes a fixed bracket 801 and a floating bracket 802 . The fixed frame 801 is fixedly connected with the frame 9 , and the floating bracket 802 is horizontally slidably connected with the fixed frame 801 . The first rotating shaft 803b is rotatably connected to the floating bracket 802 , and the second rotating shaft 804b is rotatably connected to the floating bracket 802 . Two ends of the floating bracket 802 are respectively connected to the fixed frame 801 through support springs 810 . The swing gear 807 is rotatably connected to the floating bracket 802 , and the connecting rod 805 is horizontally s...
Embodiment 3
[0058] In the middle of two consecutive commutations, the commutation control unit 8 needs to maintain the position. In order to meet the above requirements, this embodiment is further improved on the basis of embodiment 1.
[0059] Such as Figure 6 and Figure 7 As shown, in this embodiment, the swing gear 807 further includes an arc-shaped protrusion 807d, and the arc-shaped protrusion 807d is located at the opposite end of the tooth-shaped portion 807a. Specifically, the swing gear 807 is sequentially provided with a toothed portion 807a, a supporting hole 807b, a slide groove 807c and an arc-shaped protrusion 807d.
[0060] The reversing control unit 8 further includes a limit assembly 808, and the limit assembly 808 includes a housing 808a, a sliding rod 808b, a roller 808c and a limit support spring 808d. The housing 808a is fixedly connected with the floating bracket 802 . The sliding rod 808b is slidably connected to the housing 808a. One end of the limit support...
