Background technology
At present, countries in the world put into substantial amounts of capital, the unconventional petroleum resources such as exploiting coal bed methane and shale gas, but coal
Compared with conventional gas and oil exploitation, shaft bottom level change is larger, it is necessary to frequently before and after there is exploitation for the exploitation of layer gas and shale gas
Regulation is balanced, is to improve gas production efficiency, should be using the relatively low pumping unit of jig frequency, unconventionaloil pool initial stage of production, typically
It is to be exploited using the original larger load oil pumper in oil field, but as the exploitation scale of unconventionaloil pool gradually increases, it is former
The large-scale oil pumper having cannot adapt to the demand of low cost exploitation, and a large amount of large-scale oil pumpers are used as small-sized oil pumper,
Cause to waste to oilfield surface construction and equipment investment, increased unnecessary cost.
The content of the invention
The invention provides a kind of small-sized oil pumper of the exploitation needs that can meet unconventionaloil pool field, realizing can spirit
Adjustment living, whole machine floor space is small, lightweight, so as to reduce the effect of oilfield construction cost, has adapted to current to oil gas
The demand of winning apparatus.
In order to solve the above technical problems, the technical solution used in the present invention is：Small-sized oil pumper, including base, support,
Crank, polished rod eye, horse head, walking beam body, bottom bracket, tail balance beam balance device, tailing axle bearing, connecting rod crossbeam, decelerator, shield
Column, crank-pin, brake and motor assembly, the base are provided with decelerator, and the output shaft of decelerator is connected with crank one end,
The connecting rod that crank is hinged on walking beam with one end by crossbeam is connected, the support support walking beam body middle part on base, walking beam body one
End is fixed with preceding horse head, it is characterised in that the other end of the walking beam body is provided with tail balance beam balance device, the tail beam balance
Device afterbody is tubular structure, and the balance beam balance device is fixed by portable safety pin and is locked at walking beam body end.
Said structure is described further, the ballast box of the tail balance beam balance device is designed to cylindrical shape, in cylinder
Portion is designed to grid-like, and the adjustable square balancing weight of quantity can be placed in grid, and each square balancing weight passes through safety pin
It is fixed as one, ballast box is provided with two charging ports, larger particulate matter of proportion etc. can be added thereto to by charging port and filled
Work as counterweight.The base to be mounted directly on sill for low base structure, i.e. decelerator.The motor assembly is installed to
On base below support.The motor is frequency control motor.The guardrail is totally-enclosed guardrail.Described brake is side
Rotary brake.
Said structure is described further, two charging ports of the ballast box are furnished with closure, the closure leans on bolt
It is fixed on counterweight casing.
It is using the beneficial effect produced by above-mentioned technical proposal：The present invention on the basis of conventional beam-pumping unit,
A kind of small-sized oil pumper obtained from four bar parameters and balance mode are optimized with design, using pure beam balance, and designs
Special tail balance beam balance device, the square balancing weight weight in bascule is 12.5kg, and a people can be completed to taking out
The increase and decrease of oil machine balance weight, when can so meet oil-gas mining, needs frequently and the need for accurate adjustment balance, time saving and energy saving,
Save the cost that large scale equipment participates in balancing；If Oil/gas Well load is larger individually, can also be by filling out on ballast box
Mouth is filled to the inexpensive content such as sandstone is increased in ballast box to serve as counterweight, can also save input cost；It is anti-using decelerator
To the mounting technique below installation and motor preposition to support, and decelerator is set to be mounted directly on sill, these are all
Package size and main screw lift are reduced, the need for meeting the small and inexpensive exploitation of floor space.In addition, tail beam balance
Device installs simple, employs portable safety pin and fixes locked, reduces installation labour intensity.
