The working principle is as follows: when the pumping unit is shut down remotely or on site, the mechanism can brake immediately or delay to brake after the pumping unit is static, and the tensioning stroke of the brake is adjusted and the brake is locked by adjusting the linkage of a travel switch of the mechanism; when the pumping unit is started, the mechanism firstly releases the brake, and the motor of the pumping unit is unlocked and started after the brake is released. The field personnel can also shake the handle of the worm gear mechanism to adjust the position of the crank, and can also directly and manually tighten or loosen the brake.

The device is an automatic brake linkage system for remote start and stop of a petroleum beam pumping unit and a cone embedded auxiliary brake device, and the device consists of two parts: the main brake remote start-stop electric linkage actuating mechanism and the cone embedded auxiliary brake device. The main brake remote start-stop electric linkage actuating mechanism has 4 working modes, 1 remote stop, and the main brake mode is automatically locked after the pumping unit stops; 2, remotely starting the pumping unit after automatically releasing the brake in place; 3, manually performing an elastic operation mode of electric braking by starting and stopping the pumping unit on site; 4, manually performing an elastic operation mode of manual braking by starting and stopping the pumping unit on site; the cone embedded auxiliary brake device is a mechanical hard combined protection device with a secondary brake anti-slip function, which is used for manually locking when relevant maintenance operation is carried out after the field pumping unit is shut down. When the remote shutdown operation is carried out on the pumping unit, the production command center sends out a shutdown instruction of the pumping unit, the pumping unit is shut down, after the pumping unit is completely static for 30 seconds (time can be set by self), the electric brake is started, the electric push rod lead screw is contracted, the brake block is driven to hold the brake hub tightly, and the braking action is completed. When the pumping unit is started, the production command center sends a pumping unit starting command, the electric brake starts to release the brake, the electric push rod lead screw extends outwards, the brake pad is released under the action of the elastic force of the return spring and the push rod thrust, and after the brake pad is in place, the limit travel switch is triggered to start the pumping unit.

The auxiliary brake mechanism (dead brake) is a crank handle positive and negative screw rotation locking mechanism: under the condition that an original brake is not disassembled (the field installation workload is effectively reduced), a limiting spacing ring 24 is firstly installed on the outer side of an original brake wheel, three jackscrew holes 241 are uniformly distributed on the circumference of the limiting spacing ring 24, jackscrews are arranged in the jackscrew holes 241, the inner diameter of the limiting spacing ring 24 is slightly larger than the diameter of a middle shaft protruding part of the brake wheel, the three jackscrews are used for adjusting and concentricity, the end part plane is tightly attached to the end surface of a spoke of the brake wheel 14, a tight fit brake disc 21 is installed on the limiting spacing ring 24, 4 tooth sheets with nuts are installed in the spoke and correspond to installation bolt holes of the brake disc 21, high-strength bolts are installed, the spoke is clamped in a pairwise mode, and the fixation of a dead brake cone is achieved. Simple installation and strong practical operability.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
