Abstract
The utility model discloses a braking and stopping synchronizer for an oil pumping unit, the braking and stopping synchronizer comprises a braking lever, a motor, a travel switch and a signal relay; the travel switch is electrically connected with the signal relay and the braking lever, and the signal relay can control the starting and stopping of the motor. The braking and stopping synchronizer is characterized in that the travel switch is connected with the braking lever, and the signal relay can control the starting and stopping of the motor, so that the braking and stopping synchronizer achieves the purpose of braking by the operation of a person and simultaneously achieves the purpose of stopping, and lessens the labor intensity of working personnel. The utility model has the advantages of simple structure, low cost, less required components and safe and reliable motion.
Description
Technical field
The utility model relates to the used for oil extractor electric motor protective device, the device that especially a kind of brake is synchronous with shutdown.
Background technology
When at present oil pumper is plucked load, shut down, brake needs two people operation, because two people cooperate and badly easily cause shutdowns, brake asynchronous during operation, occurs burning the end of a thread easily, the problem such as not in place of braking, cause device damage, thereby bring economic loss.
The utility model content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, shutting down synchronizer and provide a kind of simple in structure, easy to operate oil pumper to brake.
The utility model is taked following technical measures: synchronizer is shut down in a kind of oil pumper brake; comprise brake lever, motor; also comprise travel switch, signal relay; described travel switch is electrically connected with signal relay, brake lever respectively, the startup of described signal relay control motor, quits work.
The beneficial effects of the utility model are to utilize travel switch and brake lever to link together, and by the startup and the shutdown of relay control motor, reach the purpose that the one man operation brake also reaches shutdown simultaneously, have alleviated staff's labour intensity.The utility model is simple in structure, and is with low cost, and required element is few, moves safe and reliable.
Description of drawings
Fig. 1 is the utility model circuit theory schematic diagram
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, synchronizer is shut down in a kind of oil pumper brake, comprises brake lever, motor; also comprise travel switch 1, signal relay 2; described travel switch 1 is electrically connected with signal relay 2, brake lever respectively, and travel switch 1 can be installed in the brake lever side, and normality is a not on-state.The startup of signal relay 2 control motors 3, quit work.
The course of work is as follows: when oil pumper brakes, and along with increase travel switch 1 conducting of brake stroke, signal relay 2 adhesives, its normally closed interlock disconnects, motor starter 4 outages, motor 3 quits work, and oil pumper brake, shutdown are finished simultaneously automatically.When releasing of brake, along with the travel switch 1 of reducing of brake stroke disconnects, signal relay 2 separates, its normally closed interlock conducting, and motor starter 4 conductings, machine operation starts oil pumper.
Claims (1)
1, synchronizer is shut down in a kind of oil pumper brake; comprise brake lever, motor; it is characterized in that also comprising travel switch, signal relay, described travel switch is electrically connected with signal relay, brake lever respectively, the startup of described signal relay control motor, quits work.
