Description
Technical field
The utility model relates to a kind of safety guard, especially relates to a kind of Crank Pin on Pumping Units safety guard.
Background technology
At present, the oil pumper adopted in field of petroleum exploitation is all walking-beam pumping unit substantially, due to the field unattended that oil pumper is mostly installed, and oil pumper is nearly all duty 24 hours every days, so running causes very large load to oil pumper for a long time.And in each parts of oil pumper, Crank Pin on Pumping Units is the parts the most easily occurring accident, there is the oil pumper rollover accident caused because Crank Pin on Pumping Units is deviate from every year.In the oil pumper used at present; substantially all Crank Pin on Pumping Units anti-loosening protector is not installed; but safeguarded by manual inspection; due to crank pin nut loosen after be not easy to realize; manual inspection is difficult to pinpoint the problems timely and effectively; and once crank pin nut loosens, oil pumper will be caused within very short time to turn over machine accident, happen occasionally so cause oil pumper to turn over machine accident.
In existing crank pin anticreep technology, one is strained by force by two connecting rods at small end pull bar, reach the object of crank pin anticreep, but it but can not find that crank pin loosens, and the crank pin loosened can produce wearing and tearing in long-term operation process so that fracture; Another kind is arranged on by detecting element on two connecting rods, and this technology just can detect when crank pin is deviate from more than 1 centimetre, extends the time of discovery accident; Also have a class to be the warning device adopting wireless electron receiving trap, this device circuit is complicated, be unfavorable for on-site maintenance, and this device can only provide warning when crank pin loosens, and can not provide protection for crank pin effective at ordinary times.
Utility model content
In order to overcome the deficiency in background technology; the utility model discloses a kind of Crank Pin on Pumping Units safety guard; pass through the utility model; not only effectively can protect Crank Pin on Pumping Units at ordinary times; prevent the corrosion of crank pin front end nut, and when crank pin loosens, warning can be sent in time; remind staff's on-call maintenance, effectively prevent the generation of crank pin case accident.
Realize the technical solution of the utility model as follows:
A kind of Crank Pin on Pumping Units safety guard, comprise warning lamp, crank pin and crank, above the crank pin perforation of crank, two ends are respectively equipped with holder, rotating shaft is provided with between holder above described crank pin perforation, described rotating shaft is provided with protective cover, in protective cover bottom surface, tail end is provided with multiple ring buckle, described multiple ring buckle is connected in rotating shaft, solar cell is provided with at the upper surface of described protective cover, above described solar cell, warning lamp is installed, wire is provided with bottom described solar cell, joint is provided with at the other end of described wire, inductor is provided with above the external thread of described crank pin front end, described crank pin top upper surface is provided with inductor interface, described inductor carries out circuit connection by the joint access inductor interface on wire, described solar cell, warning lamp and inductor are electrically connected.
Described Crank Pin on Pumping Units safety guard, the warning device in described inductor and Master Control Room carries out wireless connections.
Described Crank Pin on Pumping Units safety guard, the volume of described protective cover be greater than crank pin stretch out perforation after volume.
The beneficial effects of the utility model are, a kind of Crank Pin on Pumping Units safety guard described in the utility model, by installing protective cover in the crank pin perforation of crank, can greatly reduce and prevent rainwater dust storm from touching crank pin, effectively prevent the corrosion of crank pin; By installing inductor in crank pin front end, when crank pin upper cap nut can be made to occur to loosen, get final product induction alarm, make its operating personnel carry out fastening to crank pin nut in time, effectively avoid because crank pin nut loosens, and the crank pin caused is deviate from or is damaged; By installing solar cell on protective cover, making this device to have independent current source, avoiding and circuit hybrid junction on oil pumper, improve the safety and reliability of oil pump running; The utility model is installed simple, easy to use, staff's Timeliness coverage potential safety hazard can not only be made to keep in repair, and effectively prevent the generation of crank pin case accident.
