Abstract
The utility model relates to an auxiliary equipment of a pumping unit, in particular to a twin-well pumping unit returning frame device. The twin-well pumping unit returning frame device is composed of a roller chain, a returning frame, a reversing slide block, a roller chain connecting shaft and a belt connection plate. The reversing slide block is arranged in the returning frame, two longitudinal ends of the returning frame are respectively provided with the belt connection plate, while two lateral ends of the returning frame are respectively provided with the roller chain connecting shaft, and the outside of the roller chain connecting shaft is fixed on the roller chain. By means of the twin-well pumping unit returning frame device, reversing of a pumping unit is achieved, and the returning frame always being horizontal and stable operation of the pumping unit are guaranteed. In addition, the twin-well pumping unit returning frame device has the advantages of being simple in structure, high in reversing efficiency, low in energy consumption, wide in application scope and the like.
Description
Technical field
The utility model relates to a kind of oil pumper auxiliary equipment, and particularly a kind of twin-well oil-pumping machine comes and goes rack device.
Background technology
At present, along with the rising year by year of China's oil field oil production, the quantity of taking out well, heavy oil wells and many gas wells deeply also constantly increases, and the exploitation difficulty is increasing.And existing oil pumper stroke is shorter, no beam pumping unit slower development.The stroke of oil pumper has not only determined the tar productivity of oil pumper, and has determined the scope of application of oil pumper, particularly deep-well and heavy oil wells.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of twin-well oil-pumping machine to come and go rack device, realizes the switching-over of oil pumper; Guarantee again that simultaneously come and go frame is horizontal always, guarantees the oil pumper even running.
Its technical scheme is: mainly be made up of roller chain, round frame, switching-over slide block, roller chain connecting axle, belt junction plate; Come and go in the frame and be provided with the switching-over slide block; The vertical two ends that come and go frame are respectively equipped with the belt junction plate; Transverse ends is respectively equipped with the roller chain connecting axle, and the roller chain connecting axle outside is fixed on the roller chain.
The beneficial effect of the utility model is: realize the switching-over of oil pumper; Guarantee again that simultaneously coming and going frame is horizontal always, guarantee the oil pumper even running, have advantages such as simple in structure, that switching-over efficient is high, energy consumption is low, applied widely.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: roller chain 1, round frame 2, switching-over slide block 3, roller chain connecting axle 4, belt junction plate 5.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of roller chain 1, round frame 2, switching-over slide block 3, roller chain connecting axle 4, belt junction plate 5; Come and go and be provided with switching-over slide block 3 in the frame 2; The vertical two ends that come and go frame 2 are respectively equipped with belt junction plate 5; Transverse ends is respectively equipped with roller chain connecting axle 4, and roller chain connecting axle 4 outsides are fixed on the roller chain 1.
1 same position fixing roller chain connecting axle 4 respectively on two roller chains, roller chain connecting axle 4 passes switching-over slide block 3, can rotation in switching-over slide block 3; When round frame 2 moved to roller chain 1 end, switching-over slide block 3 can move up and down in round frame 2, realizes switching-over.Guarantee again that simultaneously come and go frame is horizontal always, guarantees the oil pumper even running.
Claims (1)
