Embodiment

[0024] combine Figure 1-4 , a beam type crank balanced oil pumping equipment, comprising a donkey head 1, a beam 2, a mounting sleeve 3 and 8 adjusters 4, the contact end of the donkey head 1 and the beam 2 is a block 11, the The contact end between the traveling beam 2 and the donkey head 1 is a slot 21, the block 11 cooperates with the slot 21, and the donkey head 1 and the traveling beam 2 are provided with screw holes. The installation sleeve 3 is sleeved at the joint between the donkey head 1 and the swimming beam 2, and a plurality of through holes 31 are provided on the installation sleeve 3. After the bolts are screwed into the through holes 31, they can be connected with the donkey head 1 and the donkey head 1. The screw holes on the beam 2 are threadedly connected, and the regulator 4 is evenly arranged on each surface of the installation sleeve 3, and each surface of the installation sleeve 3 is provided with two regulators 4. The donkey head 1, the traveling beam...

Abstract

The invention relates to the technical field of oil pumping equipment, in particular to walking beam type crank balance oil pumping equipment. The walking beam type crank balance oil pumping equipmentis characterized in that a horsehead and a walking beam have good connecting strength, when a connecting structure is unbalanced in stress, adjustment can be conducted through adjusters, damage and breakage of bolts due to uneven stress can be avoided, loosening of the joint of the horsehead and a cross beam is prevented, the walking beam type crank balance oil pumping equipment has practical significance and popularization value, is expected to produce good economic benefits and comprises the horsehead, a walking beam, a mounting sleeve and the plurality of adjusters, the horsehead is matched with the contact end of the walking beam, the mounting sleeve sleeves the joint of the horsehead and the walking beam, a plurality of through holes are formed in the mounting sleeve, and the bolts can be in threaded connection with the horsehead and the walking beam after being screwed into the through holes. Each adjuster comprises two lead screws and a sleeve, the tail ends of the lead screwsare movably arranged on the horsehead and the walking beam respectively, and the sleeve and the lead screws form a screw pair.

Description

technical field [0001] The invention relates to the technical field of oil pumping equipment, in particular to beam-type crank balanced oil pumping equipment. Background technique [0002] The pumping unit is the main lifting equipment in the rod pumping system, commonly known as the kowtow machine. According to whether the structure of the pumping unit has a beam, it can be divided into a beam pumping unit and a beam pumping unit without a beam. , the structure of the beam pumping unit is relatively simple. During the oil pumping operation, the driving mechanism provides power to drive the crank of the pumping unit to rotate at a low speed, and through the crank-connecting rod-beam mechanism, the rotational motion is changed into the vertical motion of the donkey head. The reciprocating motion in the direction, use the rope hanger to drive the well pump to work to realize oil pumping. [0003] Due to the large acceleration of the donkey head movement of the pumping unit, t...
