Abstract
The utility model relates to a drilling appliance and in particular relates to a novel frame-free super-long stroke pumping unit. The existing oil exploitation most is still implemented by virtue of up-and-down movement of the pumping unit, the drilling equipment is developing towards chain transmission, and the existing transmission mechanisms are varied, including steel wire rope transmission, four-connecting rod transmission, belt transmission, chain transmission and the like. The presently common pumping units are huge in body and relatively short in stroke, and need to be improved in efficiency. The novel frame-free super-long stroke pumping unit is designed with a small frame and even without frame, and therefore, materials are greatly saved, and meanwhile, the cost of maintaining the frame is further saved. The novel frame-free super-long stroke pumping unit is designed with a movable pulley block and mounted underground, and consequently, the stroke is greatly increased and the oil extraction efficiency is improved. Due to simple and reliable crank-slider mechanism design, the novel frame-free super-long stroke pumping unit avoids the use of parts such as a gear and thus is reduced in loss.
Description
Technical field
The utility model relates to a kind of drilling equipment, particularly a kind of novel inorganic frame ultra long stroke beam-pumping unit.
Background technology
The now exploitation of oil mostly remain by oil pumper move up and down realize, drilling equipment is to chain drive future development, transmission mechanism is varied now, comprises wire rope gearing, four link transmissions, belt transmission and chain drive etc.At present common oil pumper is bulky, and stroke is relatively short, and efficiency need to improve.
The design applies the even no frame design of small-sized frame, has saved material greatly, has more saved the expense of maintenance frame simultaneously.The design adopts running block design, under tie surface, installs, and has improved greatly stroke, has improved oil recovery efficiency.The design adopts simple and reliable slider-crank mechanism design, the application of having removed the parts such as gear, and loss reduces.
Utility model content
The purpose of this utility model is exactly for present situation, and a kind of novel inorganic frame ultra long stroke beam-pumping unit is provided, and overcomes current oil pumper bulky, the shortcoming that stroke is shorter, and its technical scheme adopting is as follows:
A kind of novel inorganic frame ultra long stroke beam-pumping unit.It comprises roller, wire rope, fixed pulley group, running block, connecting groove, horizontal slide, slide block, connecting rod, crank, crank support, ground, reduction box, motor, fixed pulley axis, fixed pulley support, balancing weight, vertically slideway, Roller Shaft, belt, small-sized frame, described roller is arranged in frame by Roller Shaft, described wire rope connects fixed pulley group and fixed pulley group and running block and slide block, described connecting groove connects running block and wire rope by axle, described slide block moves in horizontal rail, described connecting rod, crank, slide block and crank frame connect into slider-crank mechanism, described balancing weight moves in vertical rail, very littlely even ignoring of can doing of small-sized frame.
The mechanisms such as above-mentioned small-sized frame are positioned on ground, and vertical rail is positioned at ground line digs pit, and a part of belt is also positioned under ground digs pit;
The number that above-mentioned fixed pulley group and running block can be adjusted movable pulley, realizes different gearratios.
Above-mentioned horizontal slide slide block, connecting rod and crank composition crank-link mechanism, realize motion commutation function.
The utlity model has following advantage: adopt the even no frame design of small-sized frame, saved material greatly, more saved the expense of maintenance frame simultaneously; The design adopts running block design, under tie surface, installs, and has improved greatly stroke, has improved oil recovery efficiency; The design adopts simple and reliable slider-crank mechanism design, the application of having removed the parts such as gear, and loss reduces.
