Summary of the invention
The utility model to be stepped down greatly present situation to solve oil well, puts compound and step down device after providing a kind of wide-band beam-pumping unit.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions: comprise pylon, guide wheel bracket, the top fixed guide wheel support of described pylon, guide wheel bracket comprises front jockey wheel support and rear guide wheel bracket, guide wheel after fixing by rotating shaft on rear guide wheel bracket, front jockey wheel support fixes front jocket wheel by rotating shaft, described front jockey wheel support is provided with upper rail and lower guideway, rear guide wheel bracket is provided with insertion block, the end of rear guide wheel bracket fixes limited block, connected by screw-rod structure between front jockey wheel support and rear guide wheel bracket, the mechanism that steps down is put after described front jockey wheel support is provided with front jockey wheel, put the mechanism that steps down after described front jockey wheel and comprise guide wheel limited block, movable holddown, front jockey wheel axle, bolt, nut, bearing pin, postive stop baffle, the inside top of front jockey wheel support is provided with guide wheel limited block, the top outer of front jockey wheel support fixes postive stop baffle, one end of movable holddown connects front jockey wheel support by screw bolt and nut, the other end of movable holddown is by pinned connection postive stop baffle, front jockey wheel axle is provided with between described movable holddown and postive stop baffle.
The inner side of described movable holddown is wedge-shaped impression structure.
Described screw mechanism is made up of screw rod and two nuts, and one end of screw rod connects front jockey wheel support, and the other end of screw rod connects rear guide wheel bracket, and screw rod promotes front jockey wheel support guide wheel bracket slip location backward.
The beneficial effects of the utility model: structure is simple, easy to operate, time saving and energy saving again, after front jockey wheel, step down mechanism and front jockey wheel support and rear guide wheel bracket plug-in type of pendulum steps down the combination of mechanism, can realize workover treatment and to step down greatly requirement.The compound mode of stepping down of the present utility model can adopt minor diameter front jockey wheel, reduces the quality of front jockey wheel assembly, greatly reduces the overturning moment of the relative pylon outer guide of built-in insertion block; Rear pendulum is stepped down more laborsaving when making operation, simple, convenient, more science and objective.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is syndeton schematic diagrames of front jockey wheel support and rear guide wheel bracket;
Accompanying drawing 3 is the structural representations putting the mechanism that steps down after front jockey wheel;
In upper figure: pylon 1, front jockey wheel support 2, rear guide wheel bracket 3, rear guide wheel 4, front jocket wheel 5, puts the mechanism 7 that steps down after screw-rod structure 6, front jockey wheel, upper rail 2.1, lower guideway 2.2, inserts block 3.1, limited block 3.2, guide wheel limited block 7.1, movable holddown 7.2, front jockey wheel axle 7.3, bolt 7.4, nut 7.5, bearing pin 7.6, postive stop baffle 7.7.
Detailed description of the invention:
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in more detail.
