Lifting rope head of pumping unit and lifting rope

Abstract

The invention discloses a lifting rope head of a pumping unit and a lifting rope. The lifting rope head includes a lifting rope head body, a first cavity for a steel wire rope to be inserted is formedin the lifting rope head body, the first cavity is internally provided with a bolt body, and a locking seat is connected to the lower end of the lifting rope head body. According to the arrangement,the required lifting rope length is calculated according to actual needs, after the excess part is cut off, the steel wire rope is inserted into the first cavity, the bolt body is wedged along the center of the steel wire rope so that the steel wire rope is closely connected with the lifting rope head, the locking seat is installed, and it is ensured that the steel wire rope and the lifting rope head are connected reliably. Working at heights is not required, only the excess part of the steel wire rope is need to be cut, the lifting rope head can be reinstalled for use, the potential safety hazards are reduced, downtime is shortened, a new lifting rope is not required to be replaced, the used lifting rope can be repaired and reused, the cost is saved, the structure is simple, operation isconvenient, installation is easy, and the occurrence of staff hand clamping accidents are avoided effectively.

Description

technical field [0001] The invention relates to the technical field of pumping unit accessories, in particular to a braid head of an oil pumping unit and a braid. Background technique [0002] As the main equipment for surface oil production, the pumping unit is connected to the underground sucker rod through braids. The braids are composed of a certain length of steel wire rope and two braid heads installed at both ends of the wire rope. When in use, hang the braids on the donkey head of the pumping unit, and the two braid heads are connected with the sucker rod in the downhole through the rope hanger, and bear the weight of 7-10 tons in the downhole. Different models of pumping units have different lengths of braids, and braid manufacturers will make braids of corresponding specifications according to the model of pumping units. [0003] Due to factors such as downhole operations, building construction around the wellhead, and the foundation sinking of the pumping unit du...

AI Technical Summary

Problems solved by technology

However, the braid head used in the pumping unit is fixed at present, and is fixedly connected with the steel wire rope through the cold rolling process, so the length of the braid cannot be changed. The current solution is to pull the braid up to the head of the donkey and use a crane to ascend , carry out high-altitude operations, remove it and replace it with a new hair braid

However, the high-altitude operation has a low safety factor and is prone to danger. There are fewer cranes on the production site, and it is easy to be in short supply. This increases the replacement time of braids and the downtime of pumping units, reduces production efficiency, and the replaced braids cannot be used again. It causes waste, and if the new hair braid is a special size, it needs to be customized, the production cycle is long, and the processing cost is high
