Accompanying drawing explanation
Fig. 1 is overall structure front schematic view of the present utility model;
Fig. 2 is overall structure schematic rear view of the present utility model;
Fig. 3 is balance weight protective device structural scheme of mechanism of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
embodiment 1
A ratchet machine commutating long stroke beam unit, comprises brake gear 1, base 2, motor 3, ratchet chang-over speed reducing box 4, frame 5, belt crown sheave 6, mechanism 7 steps down, steel wire crown sheave 8, wire rope 9, balance weight protective device 10, balance weight 11, wide belt 12, shaft coupling 13 and driving drum 14, brake gear 1, motor 3, ratchet chang-over speed reducing box 4, frame 5, belt crown sheave 6, mechanism 7 steps down, steel wire crown sheave 8, wire rope 9, balance weight protective device 10, balance weight 11, wide belt 12, shaft coupling 13 and driving drum 14 are all arranged on base 2, and motor 3 connects ratchet chang-over speed reducing box 4, belt crown sheave 6, step down mechanism 7 and steel wire crown sheave 8 is arranged in frame 5, belt crown sheave 6 connects the mechanism 7 that steps down, steel wire crown sheave 8 connecting steel wire ropes 9, balance weight protective device connects 10 and connects balance weight 11, wide belt 12 connection frames 5, shaft coupling 13 connection for transmission cylinders 14, described balance weight protective device comprises guide rail 15, ratchet 16, wedge 17, spring 18, wire rope 9 and balance weight pull bar 19, guide rail 15 connects ratchet 16, and spring 18 connects balance weight pull bar 19, and described oil pumper adopts equilibrium principle to realize the work of oil pumper.
embodiment 2
Operating principle: starter motor after ratchet commutation gearbox setting stroke and jig frequency working system, the rotation of driven by motor gearbox.During upstroke, the rotation of driven by motor gearbox positive direction, motor and balance sysmte release energy and drive driving drum to be rotated in the forward, and driving drum drives belt and sucker rod to move upward, and oil pumper completes upstroke; When oil pumper motion arrives the upper dead center position of setting, the commutation of gear box hydraulic system, the opposite spin of driven by motor gearbox, balance weight is up, and sucker rod drives the descending down stroke that completes of belt; While arriving lower dead point position, the commutation of gear box hydraulic system, so iterative cycles completes the upper and lower stroke of oil pumper.
During normal work, at lineoutofservice signal pull effect lower spring, in compressive state, lose and carry expansion fixture block mechanism and move back and forth in guide tracked wedge block mechanism guide rail with tandem-driving bogie; When occurring that sucker rod breaks suddenly bar; the wire rope that connects balance weight and suspension point loses and carries suddenly; at this moment losing a year expansion fixture block for expansion fixture block mechanism opens automatically; be stuck in immediately on the wedge block of guide tracked wedge block mechanism; thereby balance loaded van is blocked to be safely sitting in frame; can not pound suddenly earthward protection equipment and personnel's safety.
