Abstract
The utility model relates to a pulley type long stroke oil pumping machine, comprising a base, a bracket, a head pulley, a speed reducer, and a power machine. Two sides of the head pulley are respectively and fixedly connected with a balance block hanging rope and an oil pumping rod hanging rope, and the side surface of the head pulley is fixedly connected with a small pulley. A flexible cable which is connected with a transverse beam is tied on the small pulley, and the transverse beam is connected with the crank of the speed reducer by a connecting rod. The speed reducer is driven by the power machine to drive the small pulley to rotate, the head pulley also follows the small pulley to rotate, and thereby, an oil pumping machine rod and a balance block do up-down peciprocating motion. Due to the fact that the radius of the small pulley is smaller than the radius of the head pulley, and therefore, a stroke can be increased. The pulley type long stroke oil pumping machine has compact structure and low energy consumption.
Description
The utility model relates to the pumping unit that a kind of oil well is used, and refers to a kind of long stroke oil rig of wheeled construction especially.
Many oil wells need to use the method for mechanical oil recovery in later stage exploitation, reaching the high and stable yields effect, and the employed device of mechanical oil recovery is based on pumping unit.The most frequently used pumping unit is a beam pumping unit at present, it is a four-bar type structure, this four-bar pumping unit is because of simple in structure, easy to operate and be widely used, however this beam pumping unit fork swing up and down the stroke that distance is exactly oil pumping, obvious pumping unit stroke is subjected to the restriction of four bar structures, seek out long stroke, must increase each parts particularly size and the intensity of fork, thereby make troubles for manufacturing, installation and transportation, and energy consumption is increased.
The purpose of this utility model provides that a kind of volume is little, and stroke is long, and is easy to operate, and the pumping unit used of the oil well of reliable performance, to overcome the shortcoming of prior art.
For this reason, the utility model adopts following technological scheme: it is by base 1, support 2, head sheave 4, equilibrium block 9, crossbeam 7, connecting rod 8, equilibrium block suspension rope 5, sucker rod suspension rope 3, flexible cable 6, retarder 12 and power engine 13 are formed, described head sheave 4 is positioned at and frame 2 tops, its one or both sides are consolidated with less than the steamboat 41 of head sheave 4 or non-complete cycle steamboat, equilibrium block suspension rope 5 and sucker rod suspension rope 3 lay respectively at head sheave 4 wheel face both sides, flexible cable 6 one ends are cemented on the steamboat 41 or non-complete cycle steamboat of head sheave 4 sides, the other end is connected with crossbeam 7, connecting rod 8 two ends link to each other with crank 11 on the retarder 12 with crossbeam 7 respectively, power engine 13 drives retarder 12, support 2, retarder 12 and power engine 13 all are fixed on the base 1.
The utility model transmission process is as described below: connect power supply, power source 13 is given retarder 12 with transmission of power, then by 11 drivening rods 8 of the crank on the retarder 12, crossbeam 7 and flexible cable 6, flexible cable 6 drives steamboat 41 rotations, 4 of head sheaves are rotated thereupon, and head sheave 4 is rotated sucker rod and equilibrium block 9 are pumped.Because steamboat 41 radiuses are less than head sheave 4, so can reach the purpose that increases stroke.Owing to equilibrium block 9 is housed thereby can reduces the stressed of each driving component.And the steamboat 41 general curved surface wheels that adopt can carry out curve design according to connecting rod 8 mechanism motion characteristics and crank 11 balance characteristics, with minimizing power engine 13 maximum output torques, thereby cut down the consumption of energy, and reach energy-conservation purpose.
The utility model volume is little, and compact structure is owing to adopt steamboat 41 structures of head sheave 4 and side thereof, the oil pumping stroke is increased according to the ratio of head sheave 4 radiuses with steamboat 41 radiuses, so can under the situation that does not increase the pumping unit volume, can increase the oil pumping stroke greatly, and energy consumption be low.
Accompanying drawing is the utility model structural representation.
10 is crankshaft balance weight.
