Background technology:
Existing counterweight box of vertical oil pumping unit up and down reciprocatingly moves and adopts T-shaped guide pillar and C type to lead boots mode to lead.
Existing T-shaped guide pillar and C type are led boots and are operated steadily under calm condition, but along with wind-force increases, guide pillar and lead frictional force between boots and increase; lead boots serious wear; cause gradually ballast box derailing, with the distortion that bumps of guide pillar or pylon main body, finally cause destructive malfunction, shutdown.Summary of the invention:
The vertically-guided device that the object of this invention is to provide a kind of vertical oil-pumping machine, it is simple in structure, easy to operate, and operation is simple, keeps in repair easyly, can effectively prevent ballast box derailing, has extended the application life of ballast box.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of vertically-guided device of vertical oil-pumping machine, comprise cylindricality guide rail, described cylindricality guide rail is fixed on column by guide rail bearing, described guiding device comprises the V-type directive wheel being fixedly installed on ballast box, the V groove of described V-type directive wheel coordinates with cylindricality guide rail, and described cylindricality guide rail is provided with guide rail clip.
Further concrete, described V-type directive wheel is positioned at the inner side of cylindricality guide rail.
Further concrete, described cylindricality guide rail is two, and described V-type directive wheel is four.
Further concrete, described V-type directive wheel is positioned at same plane and is uniformly distributed.
The present invention has following beneficial effect: it is simple in structure, easy to operate, and operation is simple, keeps in repair easyly, can effectively prevent ballast box derailing, has extended the application life of ballast box.
The specific embodiment:
Referring to Fig. 1, this specific embodiment is by the following technical solutions: a kind of vertically-guided device of vertical oil-pumping machine, comprise cylindricality guide rail 2, described cylindricality guide rail 2 is fixed on column by guide rail bearing 4, described guiding device comprises the V-type directive wheel 1 being fixedly installed on ballast box 5, the V groove of described V-type directive wheel 1 coordinates with cylindricality guide rail 2, and described cylindricality guide rail 2 is provided with guide rail clip 3; Described V-type directive wheel 1 is positioned at the inner side of cylindricality guide rail 2; Described cylindricality guide rail 2 is two, and described V-type directive wheel 1 is four; Described V-type directive wheel 1 is positioned at same plane and is uniformly distributed.
This specific embodiment operating principle: be that tumbling-type slides between cylindricality guide rail 2 and V-type directive wheel 1, when wind-force is larger, because cylindricality guide rail 2 only to move up and down, has effectively prevented the phenomenon of ballast box 5 derailings.
This specific embodiment has following beneficial effect: it is simple in structure, easy to operate, and operation is simple, keeps in repair easyly, can effectively prevent ballast box derailing, has extended the application life of ballast box.
