Abstract
Provided is a vertical type pumping unit well repair abdicating organization. The vertical type pumping unit well repair abdicating organization comprises a roller assembly, a limit plate, a front platform, a belt, a guide wheel assembly, a baffle, a beam hanger, a conduct combination and a truss assembly. The vertical type pumping unit well repair abdicating organization is characterized in that the roller assembly and the limit plate are installed at the top of the truss assembly, the front platform is connected with the upper portion of the front side of the truss assembly through a hinge pin, the guide wheel assembly is fixedly installed on the front portion of the front platform in inclined mode, and the baffle is installed at the outermost end of the front platform. On end of the belt is fixedly connected with the middle portion of the roller assembly, and the other end of the belt gets around the guide wheel assembly, passes through the gap of the baffle, and is connected with the beam hanger. The conduct combination is composed of two square tubes of different size in nesting mode, and the conduct combination is respectively connected with the front platform and the truss combination through the hinge pin. The vertical type pumping unit well repair abdicating organization has the advantages that when the well is repaired, the roller assembly is driven to wind the belt by using a motor, thereby driving the front platform to turn. When the well repair is finished, the vertical type pumping unit well repair abdicating organization dose not need the artificial turning or complete machine moving by a self-repeated and automatic resetting of the front platform and the guide wheel assembly, and the safety and the efficiency of well repair work are improved.
Description
Technical field
The utility model relates to a kind of vertical oil-pumping machine well workover mechanism that steps down, and belongs to oil recovery machiner technical research field.
Background technology
Workover treatment is often carried out in the oil field, and workover treatment divides light maintenance operation and heavy repair task, requires to have above the well head centered by well head the cylindrical space of at least 0.8 meter of radius during the light maintenance operation, then requires to have at least 1.5 meters cylindrical space during heavy repair task.In recent years, vertical oil-pumping machine (claiming again tower shelf type oil pumping machine) becomes a kind of development trend, at present, step down for the well workover space of vertical oil pumping well and to mainly contain two kinds of methods: the one, complete machine moves, but complete machine has moved following deficiency: need special messenger and special equipment in the moving process, the labor intensive material resources, workover cost increases; The 2nd, operating personnel climb to the oil pumper top and move the in advance ad hoc structure of design, the weak point of this method is not only inconvenient operation, and has certain danger, and this method generally can only satisfy the light maintenance job requirements, the method that still must adopt complete machine to move for heavy repair task.
Summary of the invention
In order when vertical oil pumping well carries out workover treatment, to make things convenient for, safety, effectively to abdicate the well workover space, farthest reduce workover cost and well workover time, designed a kind of vertical oil-pumping machine well workover mechanism that steps down.The step down characteristics such as mechanism has simple in structure, safety and stability, easy to operate, maintenance cost is low of a kind of vertical oil-pumping machine well workover suit to promote the use of at various novel vertical oil pumpers.
The utility model is that the technical scheme that problem that solution proposes adopts is: a kind of vertical oil-pumping machine well workover mechanism that steps down is made of roller assembly, limiting plate, front platform, belt, guide wheel assembly, baffle plate, polished rod eye, catheter combination, truss assembly, its principal character is: roller assembly and limiting plate are installed in truss assembly top, limiting plate is in roller assembly front, and front platform is connected to upper lateral part before the truss assembly by bearing pin; The guide wheel assembly tilts to be fixedly mounted on the front end of front platform, and baffle plate is installed in the outermost end of front platform; Belt one end is fixedly connected on the middle part of roller assembly, and the space that the other end is walked around the guide wheel assembly and passed baffle plate is connected with polished rod eye; Catheter combination forms by the square tube of two different sizes is nested, and an end of catheter combination is connected by bearing pin with the end of front platform, and the other end is connected by bearing pin with truss assembly front leg strut, and during front platform upset, catheter combination can free-extension.
The beneficial effects of the utility model are: twine belt by motor-driven roller assembly during well workover, the platform upset is until the limiting plate place abdicates enough well workover spaces before spurring behind the belt drive polished rod eye arrival baffle plate; The deadweight of forward platform and guide wheel assembly automatically reset after workover treatment was finished, and need not artificial upset or complete machine and moved, and had saved time and cost, had improved safety and the efficient of workover treatment.
