Description

Technical Field

[0001] The utility model relates to the technical field of oil pumping units, in particular to an oil well brake remote intelligent control device and an oil pumping unit. Background Art

[0002] The oil well brake is an important equipment in the process of oil drilling and production. It is mainly used to control the lowering or lifting speed of the drill pipe, drilling tools or pipe string in the well to ensure the safety of the operation process. It is a part of the oil drilling equipment, especially in the drilling operation and completion operation.

[0003] At present, the brakes of beam pumps must be operated on-site by employees. However, under conditions such as unclear visibility at night and bad weather, on-site operations pose safety risks. In addition, factors such as road conditions at the well site and insufficient manpower make it impossible to reach the site in time for brake control.

[0004] Publication (Announcement) No.: CN116951026A discloses a remote-controlled brake system for an oil pump, which adopts a manual and automatic integrated design. When adjusting the anti-shock distance, manual braking can be performed through a manual button, and the digital preset of the walking beam stop posture of the oil pump can be achieved through a drive control device. The brake position is more accurate, which facilitates daily management of oil wells such as adjustment of the anti-shock distance of the oil pump.

[0005] The prior art realizes manual braking by removing the push-pull rod and then combining the manual brake handle with the brake linkage rod and the brake connecting rod. The process is cumbersome and a lot of time is wasted when manual braking is needed.

[0006] Publication (announcement) number: CN211288527U, discloses a remote-controlled automatic brake device for an oil pump, which provides a reinforcement mechanism in the brake pad, aligns the positioning block with the positioning groove, and then moves the reinforcement plate forward, so that the reinforcement plate drives the positioning block to enter the inner side of the installation groove and the positioning groove respectively, and at the same time, the reinforcement plate drives the card slot to move forward, and when the reinforcement plate contacts the connecting plate, pressure is applied to the connecting plate so that the torsion spring is deformed by the pressure of the connecting plate, and when the card slot is parallel to the card plate, the card plate and the connecting plate are subjected to the elastic force of the torsion spring to enter the inner side of the card slot, thereby fixing the reinforcement plate, protecting the brake pad, facilitating subsequent replacement, and reducing safety hazards.

[0007] The prior art does not have a manual brake part, and when a fault occurs, manual braking cannot be performed, which poses a safety hazard.

[0008] Publication (Announcement) No.: CN115263251B discloses a remote automatic brake device for an oil pump, which automatically applies the brake after the oil pump is remotely stopped, and automatically releases the brake before the oil pump is remotely started. When the manual brake is applied in the local mode on site, the electric brake is in a released state, and the double grooves of the pull rod cam do not affect the manual brake performance.

[0009] The electric part of the prior art determines the locking mode by a travel switch. When the brake disc ages and the brake locking point changes, the brake may not be firm.

[0010] In short, the technical solutions of the above-disclosed technologies, the technical problems to be solved and the beneficial effects produced are all different from the present utility model. Regarding more technical features, technical problems to be solved and the beneficial effects of the present utility model, there is no technical inspiration in the above-disclosed technical documents.
