Embodiment Construction
[0022] 1. Production process steps:
[0023] 1. Braided rope:
[0024] First, 8-16 strands of high-molecular polyethylene rope are braided to form a high-molecular polyethylene rope core, and then 32-48 strands of polyester fiber rope are wrapped around the rope core to obtain continuous polyester fiber rope wrapped around the rope core. rope.
[0025] 2. Obtain the rope body:
[0026] Cut a section of rope body with a length of 12.3m from the continuous rope according to the service length requirements of the pumping unit.
[0027] 3. Prepare the cylindrical coat:
[0028] A cylindrical jacket is formed by pouring nylon rods, and one end of the cylindrical jacket is provided with a flat bottom, and a central through hole with a diameter equal to the diameter of the cable is opened in the center of the flat bottom, and the other end is open.
[0029] 4. Fix a cylindrical jacket at both ends of the rope body. The production process is:
[0030] At a distance of 10-15 cm fr...

Abstract
The invention discloses a high-molecular horsehead driving rope braid of a pouring oil pumping unit and a production method of the high-molecular horsehead driving rope braid, and relates to the technical field of ropes and oil pumping devices of oil pumping units. The production method includes the steps that polyester fiber ropes are knitted on the periphery of a high-molecular polyethylene ropecore, and a rope body is obtained; columnar outer sleeves are connected to the two ends of the rope body through colloid respectively, and protruding annular step faces perpendicular to the length direction of the rope body are arranged at the portions, on the periphery of the rope body, of the columnar outer sleeves. According to the high-molecular horsehead driving rope braid and the productionmethod, a technology is simple and reasonable; on the basis of the rope body formed by high molecular materials, the columnar outer sleeves are connected to the two ends of the rope body to form a whole. The whole high-molecular horsehead driving rope braid is made of high molecular materials, good abrasion resistance, acid resistance, alkalis resistance, weather fastness and aging resistance areachieved, the high-molecular horsehead driving rope braid is suitable for various severe environments, a production halting probability is greatly lowered, and the labor cost caused by frequent maintenance is also avoided.
Description
technical field [0001] The invention relates to the technical field of rope production, and also relates to the technical field of the oil pumping device of the pumping unit. Background technique [0002] The donkey head driving rope braid is the key part of the pumping unit, the middle ring is set on the output end of the donkey head driving device, and the ring heads at both ends of the donkey head driving rope braid extend out of the pressure plate of the rope hanger, and then extend out of the pressure plate Insert pins between the two ring heads and the connecting heads of the sucker rods, and connect nuts at both ends of the pins, so as to connect the donkey head driving rope braids with the sucker rod, and realize the sucker rod through the donkey head driving rope braids. The up and down reciprocating motion in the well is used for pumping oil. [0003] The current donkey head driving rope braids are all made of steel cables. Since the open-pit oil production wells ...
