Abstract
The utility model relates to the technical field of petroleum pumping machines and discloses a mobile-counterweight double-drum petroleum pumping machine which includes a load-bearing line shaft, a distance reducing box, heterotype walking beams, drums, a connecting rod and a crank. The load-bearing line shaft serially connects a coaxial round horsehead, double orientation gears and a distance-reducing-box upper pinion. Double external gears coaxial with a lower gear of the distance reducing box are engaged with the double hetertotype walking beams. The double drums are connected to the tail ends of the double heterotype walking beams which are connected with a tail bearing block. Double extension rods of the double drums are inserted into the sides of chains of the double orientation chain gears. The tail bearing block is connected to a speed reducer through the connecting rod and the crank. The speed reducer is connected with a motor through a belt. The mobile-counterweight double-drum petroleum pumping machine realizes increase and decrease of the pumping distance through increase and decrease of the radius of the round horsehead; through change of the angles of the drums, counterweight roll balls in the drums are enabled to move back and force freely and walking-beam front-tail-end weight adjustment, drum-front-tail-end weight adjustment and movement-gravity-ball weight adjustment are carried out so that alternating load balance equipoise during up-down strokes of any well is achieved at last.
Description
Technical field
The utility model relates to petroleum recovering equipment, is a kind of counterweight double drum type petroleum extractor that moves about.
Background technology
The counterweight of moving about double drum type petroleum extractor is compared with existing counter weight type oil pumper, has advantages of long take out distance, low energy consumption, high stability.At present domestic and international all counterweight oil pumpers, the stress alternation difference that its bascule can only reach while making upper and lower stroke reduces, and motor is not burned, and equipment can be run well.Stress alternation balance while not reaching counterweight and upper and lower stroke, can not make motor power energy-conservation effect completely.The second, because the design of horse head and walking beam is unreasonable, be subject to the restriction of the upper and lower movement angle of walking beam; Belt type pumping unit is subject to the restriction that frame is high, and stroke is not broken through 13 meters, and technological deficiency is very large.
Summary of the invention
In the present utility model structure, overturned the structure of traditional counter weight type oil pumper completely, its most the change of core be that horse head, three places adjust reprovision weights, increased and subtracted apart from case apparatus.
Horse head: in the present utility model, the change in radius of circle horse head makes it can infinitely increase or reduce the distance of taking out of petroleum extractor in theory.
Three places adjust reprovision weights: the counterweight in the present utility model is that twin-roll spin moves about before counterweight, walking beam that to adjust before heavy, cylinder tail end to adjust heavy for tail end, makes any a bite well remain that polished rod is up, the Balance of descending stress alternation.
Subtract apart from case apparatus: make moving up and down of walking beam only have 20 centimetres apart from being reduced to.
The stress alternation when counterweight of the counterweight of moving about double drum type petroleum extractor has reached upper and lower stroke completely remains Balance, makes motor power reach energy-conservation effect completely.The transformation of horse head is made full use of to round rule, stroke is broken through more than 50 meters, and frame is high is no more than 15 meters.When taking out when reaching 50 meters, steel band replaces polished rod.The mechanical stability of the counterweight of moving about double drum type petroleum extractor has also completed its science, reasonability design completely.
The counterweight double drum type petroleum extractor that moves about of my invention has been captured mechanical stability and the low energy consumption of puzzlement petroleum extractor completely, and long taking out apart from the century-old difficult problem having concurrently, makes petroleum extractor complete ultimate design.

1-1,1-2/1-2`, subtracts apart from the cogging as coaxially of case, and 1-1 is circle horse head, and 1-2/1-2` is connected and is become sprocket by chain with the pinion on base.
Cambered surface heterotypic gear key (3-1/3-1`) respectively with subtract pinion interlock outside case gear 2 lower gears coaxial.Walking beam 4-1; 4-1` and cylinder 6-1; 6-1` connects; Cylinder extension rod 7-1; 7-1` tail end inserts sprocket 1-2; Thereby in the chain of 1-2`, make spin 8 with the variation of cylinder angle, in cylinder, roll counterweight is changed in cylinder; Walking beam 4-1; 4-1` end is connected with tailing axle bearing 5; Connecting rod 9-1; The upper connection of 9-1` tailing axle bearing, lower connection bent axle 10-1; 10-1`, bent axle 10-1; The other end of 10-1` is connected with reducer 11 output shafts, and the power shaft of reducer connects motor 12.End at circle horse head 1-1 is fixed on support 13.
Specific embodiments
As shown in Figure 2, its Balance principle is that 1-1 is horse head; 1-2,1-2` are guide gear; 2 for subtracting apart from case; 3 (cambered surface heterotypic gear keys), 4 (walking beams) form special-shaped walking beam, and lower use 34 replaces; 6-1,6-1` are cylinder.Transmission reduction box drives 34 to move up and down, 34 3 drive 1-1, 1-2, 1-2`, 2 do along motion counterclockwise by concentric shafts, 1-1 drives polished rod to move up and down along moving counterclockwise, play oil pumping effect, 1-2, 1-2` drives chain to move up and down along moving counterclockwise, one side of chain drives 6-1, 6-1` moves up and down, 6-1, moving up and down of 6-1` forms the angle of 34 °, 6-1, counterweight spin in 6-1` is done the back and forth movement of physics under the condition of the gradient, thereby it is up to reach polished rod, the counterpoised balance balance of descending different suspending weights, the gradient of 34 ° of angle formation makes counterweight spin from one end Free-rolling of cylinder to the needed time of the other end, just in time equal jig frequency polished rod top dead-centre in the situation that of 3 times, bottom dead centre angle of lag is 1.4 seconds stagnant left and right times temporarily, therefore, different suspending weights and the counterweight of the upper and lower stroke of polished rod remain Balance, the move about Balance principle of counterweight double drum type petroleum extractor that Here it is.
Fig. 3 has provided the counterweight double drum type petroleum extractor plunger displacement pump that moves about stressed schematic diagram when up, and this figure shows that the weight G of sucker rod when sucker rod is up equates with counterweight F with fluid column weight G1 sum.
Fig. 4 has provided the counterweight double drum type petroleum extractor plunger displacement pump that moves about stressed schematic diagram when descending, and this figure shows that the weight G of sucker rod sucker rod when descending equates with counterweight F.
