Abstract
A beam-pumping unit brake locking device comprises a bolt (1), a support (2), a pin (3), a nut (4) and a screw rod (5), and is characterized in that the support (2) of the beam-pumping unit brake locking device is of a U-shaped structure, a through hole is formed in the left end of the support (2), rectangular round head grooves (A) are symmetrically formed in the middle of the support (2), a threaded through hole is formed in the right end of the support (2), the screw rod (5) with the top portion provided with the nut (4) penetrates through the threaded through hole in a matched mode, and the end is movably connected with the middle of the pin (3) inside the grooves (A) of the support (2). The beam-pumping unit brake locking device is novel in structure, convenient to operate, safe and reliable. Personnel injury accidents caused by brake failure when operating personnel works on a pumping unit can be avoided, and oil field safety production is guaranteed.
Description
Technical field
The utility model relates to oil field a kind of beam pumping unit braking safe locking device.
Background technique
The brake of beam pumping unit Main Function is according to need of work, pumping unit horsehead to be rested in the position of needs, then pumping unit is keeped in repair or adjusts operation.Variation along with PRODUCTION STATUS, oil well is carried out the increase of parameter adjustment, oil well operation and maintenance workload, cause oil-pump braking device malfunctioning because of reasons such as brake block wearing and tearing, oil immersion, the pulling force deficiencies of skidding, brake in actual use, in pumping unit is carried out running repairs or adjustment work, the brake failure phenomenon occurs often, and security incident occurs.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of beam pumping unit brake locking device.
The utility model is realized by following technical proposals:
The utility model comprises: bolt, support, pin, nut, screw rod.The support of its beam pumping unit brake locking device is " U " type structure, left end is provided with through hole, be connected with brake lever by bolt, be arranged with rectangular round end groove in the middle of support, right-hand member is provided with tapped through hole, on have the screw rod of nut to coordinate with tapped through hole to pass, the pin intermediate active in the groove of termination and support is connected.
Screw end head in above-mentioned beam pumping unit brake locking device is provided with six square toes, and the centre is provided with through hole.
The beneficial effects of the utility model are: novel structure, easy to operate, and safe and reliable, can avoid operator during operation, because brake failure causes personnel's injury accident, to guarantee oilfield safety production on pumping unit.
