Summary of the invention
the utility model provides a kind of wire cable rupture and loses a year protection vertical oil-pumping machine; overcome the deficiency of above-mentioned prior art; it effectively can solve one fracture any in two strand steel wire ropes be looped around on pulley; cause vertical oil-pumping machine to lose to carry; balance weight drops instantaneously, there is the problem of certain potential safety hazard.
the technical solution of the utility model is realized by following measures: a kind of wire cable rupture loses and carries protection vertical oil-pumping machine, comprises vertical oil pumping thermomechanical components; Vertical oil pumping thermomechanical components comprises wire rope and balance weight; Wire rope above balance weight is installed with the card rope assembly that two strand steel wire ropes can be mutually permanently connected.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned card rope assembly can comprise front clamp, rear clamp, locking screw screw bolt and nut; Clamp and rear clamp before the wire rope front-end and back-end of balance weight upper end are respectively equipped with, longitudinal front bayonet slot that two cross sections are circular arc is provided with in the lateral separation, rear end of front clamp, the longitudinally rear draw-in groove that two cross sections corresponding with longitudinal front bayonet slot are circular arc is provided with in the front end of rear clamp, form wire rope hole clipping between the longitudinal front bayonet slot of mutual correspondence and longitudinal rear draw-in groove, two strand steel wire ropes lay respectively in two wire rope hole clippings; Front clamp and rear clamp are respectively equipped with at least two sagittal and mutually corresponding clamp connecting holes, in clamp connecting hole, be separately installed with lock bolt, be installed with the nut that front clamp and rear fastening lock can be fastened on two strand steel wire ropes in the rear end of lock bolt respectively by screw thread.
above-mentioned front clamp and rear clamp can be respectively equipped with the clamp connecting hole of four, four clamp connecting holes lay respectively at left side and the right side of two wire rope hole clippings.
the utility model reasonable and compact in structure, easy to use; Two strand steel wire ropes of balance weight upper end can be fixedly connected with rear clamp by the front clamp of locking mutually, and structure is simple, easy accessibility; When in two strand steel wire ropes of vertical oil-pumping machine, there is fracture in one arbitrarily, by another strand steel wire rope, hanger is connected with balance weight, effectively prevent from vertical oil-pumping machine from losing instantaneously to carry, avoid bringing danger because balance weight drops to field personnel, safety is high.
