Summary of the invention
For overcoming the deficiency of above-mentioned technology, meet long stroke, commutation steadily new demand reliably, a kind of reversing arrangement for planetary gear ring type pumping unit that the utility model proposes has that structure is simple, easy to maintenance, cost of production is low, commutation is steadily reliable, can realize the advantages such as long stroke.
The purpose of this utility model is achieved through the following technical solutions:
For a reversing arrangement for planetary gear ring type pumping unit, be made up of guide rail, internal gear slide block and planet wheel and tie bar system.External impetus drives the sprocket rotation on tie-rod back shaft, sprocket wheel will be moved with transmission of power to planet wheel shaft by Chain conveyer, planet wheel shaft rotates and tie-rod is moved in the chute of internal gear slide block and realizes the swing of tie-rod, and then planet wheel is engaged with internal gear and completes internal gear slide block to pump in guide rail, the final sucker rod that drives moves and realizes oil pumping in oil fields.
The upper and lower two ends of described guide rail are respectively provided with position, pole block and position, lower pole block.
Described internal gear is assembled by two semicircle internal gears and two toothed rack and is formed, and can be changed the stroke of pumping unit, realize the oil pumping demand of different occasion by the length changing tooth bar.
Described planet wheel shaft along slide, guarantees the correct internal messing relation of internal gear and planet wheel by upper saw pulley.
The symmetrical Semi surrounding type of described internal gear slide block.
Described internal gear slide block is made up of internal gear, baffle plate, draw-in groove and connecting rod.Semicircle internal gear and tooth bar are accurately fixed on baffle plate by hinged bolts, baffle plate have and the standard pitch circle of semicircle internal gear and the equally spaced chute of the reticule of tooth bar simultaneously; The right and left of block is provided with draw-in groove to ensure that internal gear slide-block mechanism pumps on guide rail.
Described planet wheel and tie bar system are made up of planet wheel, upper saw pulley, planet wheel shaft, tie-rod, sprocket wheel, tie-bar support axle and tie-rod support.Tie-bar support axle is installed on tie-rod support, and is provided with two root system bars and two sprocket wheels; The other end installed rows spider gear shaft of two root system bars, planet wheel shaft is also provided with simultaneously two sprocket wheels, two planet wheels and two upper saw pulleys, wherein planet wheel shaft is fixedly connected with belonging between planet wheel and sprocket wheel, belongs to chain connection between planet wheel shaft and tie-rod and upper saw pulley; Undertaken moving by Chain conveyer between planet wheel shaft and tie-bar support axle and the transmission of power; The slip of upper saw pulley in chute ensure that the correct engagement between planet wheel and internal gear.
The beneficial effects of the utility model are: internal gear slide block and planet wheel adopt the mode of internal messing, improve its bearing capacity and stability; Internal gear, tie-rod, chute system can realize steadily commutation reliably, and avoid producing large vibrations and moment impact; By adjusting gear rack length, different stroke needs can be realized; There is long stroke, the commutation steadily advantage such as reliable, be applicable to conventional well oil pumping, deep well, ultradeep well pump and the occasion such as ocean oil pumping.
