Abstract
An anti-tripping device for a crank pin of an oil pumping unit comprises anti-tripping blocks, a ratchet wheel, a crank pin nut and the crank pin. An internal thread of the crank pin is connected with an external thread of the crank pin, the ratchet wheel is arranged on the crank pin nut, ratchet wheel grooves are evenly arranged on the ratchet wheel, the anti-tripping blocks are mounted in the ratchet wheel grooves and fixed onto the oil pumping unit, the ratchet wheel and the anti-tripping blocks form an anti-tripping mechanism, and the anti-tripping blocks cannot rotate. Therefore, the crank pin nut cannot be tripped, stop and tip-off of the oil pumping unit can be avoided, personal injury accidents and economic loss are prevented, the oil pumping unit can normally work, and the anti-tripping device has remarkable economic and social benefits.
Description
Technical field
The utility model is the device on the oil-field oil pumper, is a kind of oil pumping machine crank pin trip-proof device.
Background technique
The crank pins of pumping unit is to be fixed on the crank with nut, and through running for a long time, nut can become flexible, and causes the pumping unit cisco unity malfunction, influences oil well production, also can cause the pumping unit overturning, and major accident takes place, generation personnel injury and economic loss.
Summary of the invention
The purpose of the utility model is a kind of oil pumping machine crank pin trip-proof device of design, makes it prevent that fixedly the nut of oil pumping machine crank pin is threaded off, and guarantees the oil well ordinary production.
The purpose of the utility model is achieved in that and comprises anti-drop block, ratchet, crank pins nut, crank pins; The crank pins nut inner thread is connected with the crank pins outside thread; On the crank pins nut ratchet is arranged; Evenly be provided with ratchet slot on the ratchet, anti-drop block is installed in the ratchet slot, anti-drop block is fixed on the pumping unit.
The beneficial effect of the utility model is: ratchet and anti-drop block are formed escapement; Anti-switch block can not rotate, and therefore, the crank pins nut can not threaded off; Can avoid shutdown of pumping machine and overturning takes place; Personal injury accident and economic loss can not take place, oil pumping function proper functioning has remarkable economic efficiency and social benefit.
