Abstract

The utility model discloses an automatic braking force regulating device for a screw oil pump and particularly relates to an oil field screw oil pump automatic ground braking force regulating device. The problems that during oilfield exploitation, when the screw oil pump halts or is jammed during operation, parts on a ground driving device are thrown out at a high speed, accidents are caused, and the safety of oil field workers is poor are solved. A branch pipe is respectively is rotating connection with a casing and a base, a braking disk connecting pipe is sleeved outside the branch pipe, the braking disk connection pipe is connected with a braking base disk fixedly, the braking base disk is installed on the base, two ratchet wheels are installed on the branch pipe fixedly, pawls are installed on the upper end face of the braking disk, the braking disk is sleeved on the branch pipe, two levers are installed on the braking pipe, balance weight blocks are sleeved on the levers, the levers are connected with multi-functional supports, special-shaped cams are installed on side walls of the levels, two multi-functional supports are installed on the braking base disk fixedly, and a friction sheet is installed on a side wall of a friction sheet fixing support. The device is applied to the technical field of oilfield exploitation.

Description

Technical field [0001] The invention relates to the technical field of oilfield exploitation, in particular to an automatic adjustment device for the ground braking force of a screw oil pump in an oilfield. Background technique [0002] At present, the power source of the screw oil pump in the oil field is the ground motor through the gearbox to change the speed and slowly twist the sucker rod up to several hundred meters to drive the downhole screw pump rotor to rotate and lift the downhole liquid to the ground, due to the screw pump rotor and the surface drive device The distance between the screw pumps is long. Therefore, to make the screw oil pump work, the sucker rod must store enough energy (elastic energy) to drive the downhole screw pump to work; also when the screw pump is stopped or the stuck pump is stopped, due to pumping The driving force of the oil rod disappears instantly, and the ground equipment has anti-reversal, which is easy to cause shutdown. The energy store...
