One-touch smart brake device of pumping unit

Abstract

The invention relates to a one-touch smart brake device of a pumping unit. The one-touch smart brake device comprises a brake, a programmable controller and a sensor. The sensor is used for collecting signals and sending the signals to the programmable controller to control the brake by means of programming, so that start and stop of the pumping unit and control of stop position of the pumping unit are achieved. The brake comprises a speed reducer (10), a brake actuating mechanism and a self-locking mechanism (11); the speed reducer (10) comprises a speed reducer shaft (9), a brake disc (6), connecting plate fixing columns (12) and a connecting plate (13); the brake actuating mechanism comprises a magnetism device and a brake device and is fixed on the connecting plate (13); the self-locking mechanism (11) comprises a brake disc positioning hole (14), a cylinder (15) and an energy storage device (18) and is also fixed on the connecting plate (13). One-touch operation of the brake device is realized on site. Smart control and remote control of the brake device are realized, the pumping unit can be stopped at the optimal starting position, and purposes of energy saving and safety are achieved.

Description

technical field [0001] The invention relates to oilfield production equipment, in particular to a braking device for a pumping unit. Background technique [0002] At present, most of the braking (braking) systems widely used in oil fields are manual braking, which is difficult to operate, unable to control the parking position, and dangerous. Although some other semi-automatic braking devices solve the problem of difficult control, there are still operating steps Complex, uncontrollable problem of parking position. [0003] The manual brake relies on manpower to operate the mechanical brake. Because the pumping unit has a large parking inertia, it is not suitable for control, and there are personal safety problems. In addition, it will also damage the pumping unit; [0004] The semi-automatic brake device mainly includes a brake actuator and an electric control cabinet. The actuator mainly uses electromagnetic force for braking, and the electric control cabinet is operated...

AI Technical Summary

Problems solved by technology

[0007] Therefore, the semi-automatic brake device uses an electromagnetic force brake actuator to solve the manpower problem, but the operation steps are complicated, and the buttons need to be manually pressed in sequence, and the position cannot be judged, so it cannot be precisely positioned, and it is impossible to control where the pumping unit stops. ;resulting in high energy consumption during start-up; it simply uses an actuator instead of manual labor, and does not have the function of intelligent control; there are potential safety hazards, such as the safety pin is placed and pushed out, and manual inspection is still required to see if it is in place, which increases the operating time dangerous
