Abstract

The utility model discloses a kind of oil pumping machine crank balance weight shifter, it is characterized in that by the way of turning parts into the whole, outside occlusion ratchet, drive rod, hand-operated rocker arm lever three are connected in order.Positioned by outboard gears, inside lever movement effectively controls the sliding speed of balance weight；Get around pumping unit connecting bar, build operating platform, by reduction box of the opereating specification on the outside of balance weight on the inside of steering, effectively mitigate labor strength, improve the operating efficiency of balancing, reduce the potential safety hazard of operation.

Description

A kind of oil pumping machine crank balance weight shifter

Technical field：

The utility model belongs to the balancing tool used in field of oil field oil extraction, especially a kind of oil pumping machine crank balance weight Shifter.

Background technology：

Current field production management is become more meticulous increasingly, and oil pump energy-saving consumption reduction, Analysis of Oil Well System Efficiency, oil pumper are run Balance requires more and more higher, and the balancing workload of oil pumper increasingly increases therewith.Needed during balancing according to test Current conditions move oil pumping machine crank balance weight, and this operation is more time-consuming, while there is potential safety hazard.Moving During dynamic crankshaft balance weight, position of the balance weight generally not as required by operating personnel stops, or even balance weight can be slided voluntarily sometimes It is dynamic, cause crank tooth to damage.Simultaneously with existing hand-operated moving ratchet in mobile balanced block, there is pumping unit connecting bar and hinder shifting The problem of dynamic pawl wheel, it is therefore desirable to more than two people operated, i.e., there is a people to shake dynamic balance weight, and another person uses Crowbar mobile balanced block, also needs a people to control the slip of crank block in the other end of crank block.Whole process is very time-consuming laborious, And there is great risk.

Utility model content：

In order to overcome the shortcomings of that existing hand-operated moving ratchet is wasted time and energy, there is larger potential safety hazard when in use, this Utility model provides a kind of oil pumping machine crank balance weight shifter, and the crankshaft balance weight shifter is connected in order by each part Connect, reach safety, purpose that is steady, effectively moving oil pumping machine crank balance weight.

The utility model is adopted the technical scheme that：The crankshaft balance weight shifter, including outside occlusion ratchet, driving Bar, hand-operated rocker arm lever, the square bar at drive rod two ends, outside occlusion ratchet square hole and hand-operated rocker arm lever square Hole.The square bars of the long 70mm of square hole and drive rod of outside occlusion ratchet are riveted, the square hole of hand-operated rocker arm lever with The square bar rivetings of the long 35mm of drive rod.

The utility model has an advantageous effect in that：Due to taking such scheme, outboard gears are positioned during normal operating, interior Side lever movement, effectively controls the sliding speed of balance weight；Get around oil pumping connecting rod, build operating platform, by opereating specification by Reduction box on the inside of being turned on the outside of balance weight, effectively mitigates labor strength, improves the operating efficiency of balancing, reduces behaviour The potential safety hazard of work.

Brief description of the drawings：

Fig. 1 is a kind of oil pumping machine crank balance weight shifter design of part schematic diagram of the utility model.

Fig. 2 is that a kind of oil pumping machine crank balance weight shifter part of the utility model is shifted one's position structural representation

Fig. 3 is a kind of oil pumping machine crank balance weight shifter structural representation of the utility model.

Ratchet, 2- drive rods, 3- hand-operated rocker arm levers are engaged in figure on the outside of 1-.

Embodiment：

The utility model is described in further detail below in conjunction with the accompanying drawings：

As shown in accompanying drawing, the oil pumping machine crank balance weight shifter includes outside occlusion ratchet 1, drive rod 2, hand-operated rocker arm There is square bar 4,5 at lever 3, drive rod two ends, and outside occlusion ratchet has square hole 6, and hand-operated rocker arm lever has square hole 7.The square bars 4 of the square hole 6 and long 70mm of drive rod of outside occlusion ratchet are riveted, the square hole 7 of hand-operated rocker arm lever Riveted with the square bars 5 of the long 35mm of drive rod.Outside occlusion ratchet 1, drive rod 2, the three of hand-operated rocker arm lever 3 have during balancing Sequence is connected.Positioned by outboard gears, inside lever movement effectively controls the sliding speed of balance weight；Get around oil pumping connecting rod, Operating platform is built, by reduction box of the opereating specification on the outside of balance weight on the inside of steering, effectively mitigates labor strength, improves The operating efficiency of balancing, reduces the potential safety hazard of operation.
