Description

Two belt roller formula oil pumpers
Technical field
The present invention relates to the oil pumper that the oil field is used, particularly a kind of pair of belt roller formula oil pumper.
Background technology
In the oil exploitation, producing well generally all uses traditional beam pumping unit, and this machine mainly is made up of walking beam, horse head, support, crossbeam, connecting rod crank mechanism, dynamic retarding mechanism, for oil exploitation contributes, for energy-saving and cost-reducing, Chinese patent CN2537812 has announced a kind of " the compound tail boom slide balance of curved beam oil pumper ", mainly by horse head, walking beam, support, crossbeam, connecting rod, crank, dynamic retarding mechanism forms, and purpose is oil pumping and energy-saving and cost-reducing.But this device exists following shortcoming or deficiency: 1. big in walking beam adjusted balance difficulty; 2. can't improve stroke; 3. complex structure, weight is big, and consumptive material is many.
Summary of the invention
The object of the invention provides a kind of pair of belt roller formula oil pumper; adopt frame and go up and low-speed big automatic reverse motor, power drum, the anti-mistake are installed are carried the combining structure that protection brake, two belt and counterweight directly link to each other; simple and reasonable reliable; can the simple realization long stroke, the shortcoming or the deficiency that overcome effectively or avoided existing in the above-mentioned prior art.
Of the present invention pair of belt roller formula oil pumper; comprise guardrail; motor; the anti-mistake carried the protection brake; set upright cylinder; the suspending weight belt; the balance belt; security platform; balance weight; electric control box; frame; base; tiltedly draw support; power drum and cylinder bearing; it is characterized in that in the guardrail of described frame top motor being installed; power drum; cylinder bearing and anti-the mistake are carried the protection brake; balance belt one end is connected with power drum; the other end is connected on the balance weight; suspending weight belt one end is connected on the balance weight; the other end is walked around power drum and is connected with the well head load with the balance belt; the frame outside is equipped with security platform; tiltedly draw and support and electric control box, frame lower is equipped with base.
Wherein, described motor is a low-speed big automatic reverse motor.Described motor output shaft carries the protection brake with power drum and anti-mistake in turn and is connected.Described power drum is installed on the cylinder bearing, is equipped with under the power drum and sets upright cylinder.Described electric control box is installed on the base of frame.Described frame is the frame shelf structure, and guardrail 1 is installed on the top of frame, and balance weight places in the rack framework.The described cylinder of setting upright is two, is installed on respectively on the frame of power drum front and rear portions lower end.Described suspending weight belt, balance belt are flat wideband structural.Described balance belt one end connects and is wound on the power drum, and the other end is connected on the balance weight.Described balance belt be installed on the suspending weight belt below, the suspending weight belt is taken above the balance belt, suspending weight belt one end is connected with the well head load, the other end is connected on the balance weight.
The present invention has following advantage compared with prior art:
1, adopt long stroke, low jig frequency, oil pumper reduces loss of plunger stroke, system effectiveness height.
2, be easy to adjust the stroke jig frequency, only need increase support height when improving stroke, get final product otherwise only need reduce support height; Jig frequency only needs to adjust motor speed by control cabinet and gets final product.
3, good balance effect, balance weight directly links to each other with sucker rod by the suspending weight belt, and around riding on power drum and the balance belt, reaches accurate balance.
4, energy-conservation obviously owing to adopted accurate balance, the load of fluid column 1/2 is only born in the output of low-speed big motor, has significantly reduced the motor maximum torque installed power, operates steadily, and transmission link is few, and is energy-conservation obvious.
5, adopt decelerator-free, no walking beam structure, rational in infrastructure, machine volume is little, saves steel, and is simple compact.
6, the balance belt on power drum be put, around rolling movement, the suspending weight skin is rolling movement on the balance belt, has the anti-effect of carrying protective effect and increasing suspending weight belt frictional force of losing.
