Abstract
The utility model relates to a novel beam-pumping unit which adopts a coaxial line single output step-down gear to replace the double reduction gear of the prior art, so the volume of the beam-pumping unit is greatly reduced, the weight is lighted, the price is lowered and the operating performance is more steady and reliable. The utility model is suitable for being used in mountain areas. The design of a counterweight adjusting mechanism, a crank connecting rod mechanism, etc. of the beam-pumping unit improves the equilibrium property and the operating performance of the beam-pumping unit. The utility model has the advantages of favorable balancing effect, convenient use and high safety.
Description
The utility model belongs to the oil field machinery oil manufacturing field of equipment.
Background technique of the present utility model is: conventional formula pumping unit (CONVENTIONAL PUMPING UNITS) is the conventional pumping unit that has used both at home and abroad, they are power by motor or internal-combustion engine, by v belt with transmission of power to the gear reducer input shaft of double reduction, after slowing down, power continues to be sent on the connecting rod of pumping unit from reducer output shaft.Conventional formula pumping unit has paired connecting rod, and connecting rod is sent to the walking beam afterbody with power, and walking beam is swung up and down, thereby pumping unit just can reach the purpose of pumping crude oil up and down.
Purpose of design of the present utility model is: cancel double reduction gear of the prior art, the new pumping unit that to change two brace and connecting rod frameworks be the half crank linkage mechanism.
Design proposal of the present utility model is:
1, cancelled traditional double reduction gear, alternative is coaxial line list output decelerator (5).
2, owing to adopted coaxial line list output decelerator, therefore has only an end output shaft (double reduction gear has two output axle heads), adorn crank (6) linkage mechanism (8) of one pair of single armed on the output shaft, rather than conventional formula pumping unit there are two connecting rods.
3, owing to be the half crank linkage mechanism, so spin balancing pouring weight (7) is arranged on the crank of single armed.
4, for ease of regulating and improving equilibrium response, the walking beam afterbody also can add counterweight block (10), make adjusting balance can take independent balance of walking beam afterbody or crank to rotate the mode of independent balance, the combined balance system mode that also can take walking beam afterbody balance and crank spin balancing to superpose.
5, in order to keep the half crank linkage mechanism to be unlikely at the volley because of the assembling reason causes connecting rod to suppress strength, so connecting rod top and X-axis is made in walking beam afterbody joint, Y-axis can double-swing pin rocker bearing (9).
6, because this axial retarder has only an end input shaft, so input shaft end removes and to be equipped with transmission pulley links by v belt (3) and power engine (1), also is provided with internal expansion type or hem type mechanical friction braking brake (2) or establishes electromagnetic brake.
7, other structure of this new pumping unit, is similar with support (4) etc. to conventional formula pumping unit as walking beam (12), horse head (13), support (11), wire rope and sucker rod rope hanger (14), therefore this same levels new pumping unit can be general with the identical parts of conventional formula pumping unit, brought many conveniences for transforming conventional formula pumping unit.
8, detailed structure scheme: new pumping unit, wire rope and beam hanger rope hanger (14) are connected with horse head (13), one end of walking beam (12) connects with horse head (13), the front-axle beam of walking beam is hinged by articulated elements and support (11), one end of connecting rod (8) is by having X, Y-axis double-swing pin rocker bearing (9) is hinged with the back rest of walking beam, the other end of connecting rod (8) is connected with crank (6), one end and the spin balancing of crank (6) reconnect, the other end of crank (6) is connected with the pto of coaxial line list output decelerator (5), coaxial line list output decelerator (5) is fixed on the base of support (11) by support (4), motor or internal-combustion engine (1) are fixed on the base of support (11) and adopt v belt (3) to give coaxial line list output decelerator (5) with transmission of power, and braking mechanism (2) is positioned on the base of support (11).Connecting rod (8) and crank (6) constitute the half crank linkage mechanism.The structure of the adjustment balancer weight of new pumping unit is the combined balance system that independent balance of walking beam (12) afterbody or crank rotate independent balance or walking beam afterbody balance and the stack of crank spin balancing.Walking beam counterbalance (10) is positioned at the afterbody of walking beam (12).
Description of drawings:
The utility model is compared with background technique, and the one, adopt coaxial line list output decelerator to be used for the design of pumping unit, make that its volume reduces, weight saving, cheap, stable and reliable working performance, be convenient to the mountain area and use; The 2nd, the design of pumping unit adjustment balance and connecting rod is convenient to regulate and improve the equilibrium response and the service behaviour of pumping unit.
Fig. 1 is a kind of main TV structure schematic representation of new pumping unit.
Fig. 2 is a kind of plan structure schematic representation of new pumping unit.
1 and 2 pair of the utility model is done following narration in conjunction with the accompanying drawings.
Wire rope and beam hanger rope hanger (14) are connected with horse head (13), one end of walking beam (12) connects with horse head (13), the front-axle beam of walking beam is hinged by articulated elements and support (11), one end of connecting rod (8) is by having X, Y-axis bidirectional swinging pin rocker bearing (9) is hinged with the back rest of walking beam, the other end of connecting rod (8) and crank (6) are for flexibly connecting, one end and the spin balancing of crank (6) reconnect, the other end of crank (6) is connected with the pto of coaxial line list output decelerator (5), coaxial line list output decelerator (5) is fixed on the base of frame (11) by support (4), motor or internal-combustion engine (1) are fixed on the base of support (11) and adopt v belt (3) to give coaxial line list output decelerator (5) with transmission of power, braking mechanism (2) is positioned on the base of support (11), its brake modes is same as the prior art, walking beam counterbalance (10) is fixed on the afterbody of walking beam (12), and purpose is a balance of being convenient to regulate and improve pumping unit.
