Abstract
The utility model relates to a walking beam type braking device of an oil pumping machine in the oil field, in particular to an anti-theft device of a braking hoop of a oil pumping machine. In the technical proposal, an external cylinder is arranged on the fixing bolt of the braking hoop; a coded lock and a sealing cover are arranged in the external cylinder; the external cylinder consists of a longer-diameter cylinder and a shorter-diameter cylinder; the inner wall of the shorter-diameter cylinder is provided with an annular groove; the bulge at the inner end of the coded lock matches the annular groove; the sealing cover is arranged at the outer end of the longer-diameter cylinder. The anti-theft device of the braking hoop of the oil pumping machine has the beneficial effect of high anti-theft performances because of a plurality of anti-theft layers; the original braking hoop and the fixing bolt are not changed; the anti-theft device can be added onto the oil pumping machine, which is quire simple and practical. In addition, the anti-theft device reduces the stopping times of the oil well as a result of theft, improves the time rate of oil exploration, guarantees the normal operation of the equipment, and prevents the insecurity accidents.
Description
One, technical field:
The utility model relates to a kind of beam pumping unit braking device, particularly relates to a kind of pumping unit brake hoop anti-theft device.
Two, background technique:
At present, the oil field is along with the prolongation of exploitation time, the corresponding increase of comprehensive regulation difficulty, the stolen phenomenon of oilfield material is now serious day by day, particularly the stolen phenomenon of pumping unit accessory is more and more serious, and the stolen phenomenon of brake hoop is serious day by day so far, has had a strong impact on the normal operation of pumping unit.Because braking device plays an important role in the every operation of beam pumping unit; all must under the state of shutting down, brake, cutting off the power supply, carry out in any operation on the pumping unit; it plays the effect of guarantee to the Security of operation; very big loss has been brought to enterprise in the stolen back of brake hoop; because special-purpose anti-theft device is not bound round in brake; usually the way that adopts is that the weldering of brake hoop retaining screw is dead, but the problem that exists like this is to bring a lot of inconvenience to operation.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of pumping unit brake hoop anti-theft device is provided, and solves the oil field stolen problem of pumping unit brake hoop in process of production.
Its technological scheme is: install urceolus on the fixing bolt of brake hoop, be provided with cipher lock and sealing cover in the urceolus; Described urceolus is made up of large diameter cylinder and small diameter cylinder, is provided with circular groove at the inwall of small diameter cylinder, and the inner projection of cipher lock is cooperated with circular groove; Outer end at described large diameter cylinder is provided with sealing cover.
The beneficial effects of the utility model are: multilayer is antitheft, and theftproof performance is higher, and does not change original brake hoop and fixing bolt, just adds this anti-theft device, and very letter is practical; In addition, reduced the stolen well number of times that stops, rate when having improved oil recovery has guaranteed the normal operation of equipment, has avoided the generation of dangerous accident.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described: its technological scheme is: install urceolus on the fixing bolt of brake hoop, be provided with cipher lock 3 and sealing cover 2 in the urceolus; Described urceolus is that the large diameter cylinder 1 of 90mm and the small diameter cylinder 4 of external diameter 78mm are formed by external diameter, is provided with circular groove at the inwall of small diameter cylinder, and the inner projection of cipher lock is cooperated with circular groove; Be provided with sealing cover 2 in the outer end of described large diameter cylinder 1.
Wherein, four cipher locks that have the tapered end of password are housed on the cipher lock, the password that has only four tapered ends certainly, also can adopt other locks well-known to those skilled in the art all to just opening after last.
When the utility model is installed in pumping unit installation brake hoop, the spanner place circle of beating of bolt is wrapped, if want to unload the brake hoop, the outer tubular device of common handling instrument rotational fixation bolt outside, it can play antitheft effect, in order to increase theftproof performance along with handling instrument rotates together, put into cipher lock again, refill at last and have externally threaded sealing cover.
