Abstract
The utility model relates to a rod pumping well braking device, in particular to a theftproof electromagnetic brake of an oil pumping unit. The technical scheme is as follows: the theftproof electromagnetic brake of the oil pumping unit comprises an electromagnetic pulse generator, an oil pump unit input shaft, a brake magnetic wheel, a secondary braking preventer, a brake disc, a pullback disc, a shaft end pressure plate, bolts, a power line and an external power supply; the shaft end pressure plate, the pullback disc, the brake disc and the brake magnetic wheel are fixed on the oil pump shaft input shaft in sequence from the outside to the inside; the shaft end pressure plate is connected with the pullback disc and the brake disc through the bolts; the brake magnetic wheel is connected with the brake disc through the secondary braking preventer; the brake magnetic wheel is connected with the electromagnetic pulse generator through the power line; and the electromagnetic pulse generator is connected with the external power supply. The theftproof electromagnetic brake of the oil pumping unit has the beneficial effects of high safety degree, easiness for automatic management, favorable theftproof function, long service life and reduction of maintenance cost; in addition, the electromagnetic pulse generator automatically brakes when no rotation speed of a reduction gearbox is input, so that the aim of protecting the reduction gearbox is achieved.
Description
Technical field
The utility model relates to a kind of pumping well braking device, particularly a kind of pumping unit antitheft electromagnetic brake.
Background technique
Electromagnetic brake is a kind of master end torsion to be conveyed to the connector of passive side, can combine freely according to needs, cuts off or brakes, and comes start because of using electromagnetic force, is referred to as magnetic clutch, break, and it is fast to have speed of response, advantages of simple structure and simple.Electromagnetic brake is the important tool in the oil-field oil pumper operation; Because the pumping unit great majority are positioned at the field; Stolen phenomenon often appears in the electromagnetic brake on the pumping unit, causes speed reducer to destroy easily during the skidding of pumping well, can't realize automatic management.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, and a kind of pumping unit antitheft electromagnetic brake is provided, and safety rate is high, is easy to automatic management.
Its technological scheme is: comprise electromagnetic pulse generator, pumping unit input shaft, break magnet-wheel, secondary braking preventer, brake disc, oppositely draw dish, axle head platen, bolt, power line and external power supply; The axle head platen, oppositely draw dish, brake disc, break magnet-wheel ecto-entad to be fixed on successively on the pumping unit input shaft; The axle head platen oppositely draws dish and brake disc through the bolt connection; The break magnet-wheel is connected through the secondary braking preventer with brake disc; The break magnet-wheel connects electromagnetic pulse generator through power line, and electromagnetic pulse generator connects external power supply.
The beneficial effect of the utility model is: safety rate is high, and when speed reducer did not have the rotating speed input, electromagnetic pulse generator reached the purpose of protection speed reducer with Braking mode; Be easy to automatic management, can realize distant control through location or remote controller; Have good anti-theft feature, long service life can reduce repeatedly and drop into, and practices thrift maintenance cost.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: electromagnetic pulse generator 1, pumping unit input shaft 2, break magnet-wheel 3, secondary braking preventer 4, brake disc 5, oppositely draw dish 6, axle head platen 7, bolt 8, power line 9.
Embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises electromagnetic pulse generator 1, pumping unit input shaft 2, break magnet-wheel 3, secondary braking preventer 4, brake disc 5, oppositely draws dish 6, axle head platen 7, bolt 8, power line 9 and external power supply; Axle head platen 7, oppositely draw dish 6, brake disc 5 and break magnet-wheel 3 ecto-entads to be fixed on successively on the pumping unit input shaft 2; Axle head platen 7 oppositely draws dish 6 and brake disc 5 through bolt 8 connections; Break magnet-wheel 3 is connected through secondary braking preventer 4 with brake disc 5; Break magnet-wheel 3 connects electromagnetic pulse generator 1 through power line 8, and electromagnetic pulse generator 1 connects external power supply.
Safety rate is high, and control voltage is direct current 24-160V, and when speed reducer did not have the rotating speed input, electromagnetic pulse generator reached the purpose of protection speed reducer with Braking mode; Be easy to automatic management, can realize distant control through location or remote controller, no easily damaged parts need not adjustment, once safety, lifelong being benefited; The Applicable temperature scope is wide, but-40 ℃ ~ 70 ℃ interior proper functioning of scope; Have anti-theft feature, long service life can reduce repeatedly and drop into, and practices thrift maintenance cost.
