Abstract
The utility model relates to a screw type device for moving oil-pumping equipment. The screw type device consists of a left-hand screw nut, fixing screw nails, a right-hand screw nut and a lead screw, wherein the left-hand screw nut is connected with the upper part of the lead screw; the right-hand screw nut is fixed on slide rails by the fixing screw nails; threads of the lead screw are screwed with the right-hand screw nut; the upper section of the lead screw comprises left-hand male threads; the lower section of the lead screw comprises right-hand male threads; the left-hand screw nut and the upper part of the lead screw are connected with left-hand male threads through the left-hand male threads on the lead screw; the oil-pumping equipment is moved to a required position through rotating the lead screw; and a large axial thrust can be generated by rotating the lead screw. Thus, the screw type device has the advantages of reaching the aim of designing, time saving and labor saving, low labor intensity of operating personnel, high degree of automation, capability of tightening a belt without interrupting a machine, short time for finishing moving the oil-pumping equipment, increasing the working time of the equipment and enhancing the economic benefit of the equipment.
Description
Technical field
The utility model is the device of oil field oil recovery usefulness, is a kind of screw pumping unit mobile device.
Background technology
In the oil pumping of oil field; Oil pumper drives sucker rod, oil well pump moves back and forth oil pumping; The essential motor of installing on the oil pumper is earlier motor to be put in the appropriate location when motor is installed, and driving belt is installed on motor and the belt of oil pumping machine wheel again; Adjust motor then and make the driving belt tensioning, by the bolt group motor base is fixed on the motor track at last.During the adjustment motor, unclamp the motor fixed screw earlier, again with crowbar or jackscrew mobile motor, this move mode trouble, effort, the used time of mobile motor is long.
Summary of the invention
The purpose of the utility model provides a kind of screw pumping unit mobile device, and it is convenient, fast, laborsaving to move it pumping unit.
The purpose of the utility model is achieved in that by left-hand thread nut, setscrew, right-hand thread nut, leading screw to be formed; The left-hand thread nut is connected with leading screw top; The right-hand thread nut is fixed on the slide rail by setscrew, and threads of lead screw and right-hand thread nut screwing, leading screw epimere are the left-hand thread male thread; The leading screw hypomere is the right-hand thread male thread, and the left-hand thread nut is connected with the left-hand thread male thread by the left-hand thread male thread on it with leading screw top.
The beneficial effect of the utility model is: rotating threaded shaft moves to needed position with pumping unit, because rotating threaded shaft can produce very big end thrust, therefore; The utility model can reach purpose of design, and is time saving and energy saving, and operator's labour intensity is low; Automaticity is high, can not shut down tightening belt, accomplishes and moves pumping unit time weak point; The working time of increase equipment, the economic benefit of raising equipment.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 the utility model embodiment is described.
Can know by Fig. 1; The embodiment of the utility model is made up of fixedly left-hand thread nut 1, screw 2, setscrew 2, right-hand thread nut 3, leading screw 4, slide rail 5, and left-hand thread nut 1 is connected with leading screw 4 tops, and right-hand thread nut 3 is fixed on the slide rail 5 by setscrew 2; Leading screw 4 screw threads and right-hand thread nut 3 screw; Leading screw 4 epimeres are the left-hand thread male thread, and leading screw 4 hypomeres are the right-hand thread male thread, and left-hand thread nut 1 is connected with the left-hand thread male thread by the left-hand thread male thread on it with leading screw 4 tops.
During use, with the left-hand thread fixed by nut on pumping unit, rotating threaded shaft 4; Left-hand thread nut 1, right-hand thread nut 3 do not rotate after fixing, and right-hand thread nut 3 transfixions, so; During rotating threaded shaft 4, leading screw 4 promotes button nut 1 and moves ahead, and pumping-unit motor is moved on to needed position; Because rotating threaded shaft 4 can produce very big end thrust, thereby accomplishes the pumping unit mobile working quickly and easily.Because the leading screw epimere is the left-hand thread male thread, be connected with leading screw top left-hand thread male thread, during rotating threaded shaft 4, leading screw 4 produces with left-hand thread nut 1 and relatively moves, thereby moves pumping unit more fast.
