Abstract

The utility model relates to a crank connecting rod type beam-free oil pumping machine. The rotary movement of a power device is changed to the vertical movement from top to bottom for driving a sucker rod through an adjustable trigone bracket, a fixed pulley which is arranged at the top part of the bracket, a movable pulley which is arranged at one end of a cross rod, and a device which is wound by a rope hanger, so that an oil pump is driven to carry out the work of oil absorption and oil drain. The utility model solves the problems of the run out tolerance of a horse head and the scissors difference of a crank. When a well is repaired, the bracket can be reversed in a reversal way, and the operation can not be affected. The utility model has the advantages of simple structure, light weight, good performance and simple manufacturing process. According to the matching change of the pulley block, the working range with wider stroke can be satisfied.

Description

Crank-guide blue elephant

The utility model relates to that petroleum production crude oil elevating mechanism---crank-linkage type does not have the beam pumping unit.

The utility model improves development on the beam pumping unit basis and comes.

Current, public pumping unit, because walking beam and horse head are arranged, weight increases, easily swing brings the sucker rod accident to increase, and influences crude output.

The utility model purpose, it is little to provide a kind of volume, in light weight, easy to install, the novel device that the sucker rod accident is few.

The purpose of this utility model is to realize like this, adjustable triangular support, supporting leg links to each other with base [14] with movable joint [9], [11] before and after it, cantilever tip is equipped with static pulley [1], cross bar [22] connects movable pulley [6], and rope hanger [5] one ends are fixed on the support, around interlock pulley [6], static pulley [1] is sagging, and its other end is equipped with transverse slat and links to each other with the oil pump bar with tapered sleeve.Motor [16] drives speed reducer [13] by belt [15], crank [12] counterweight [19] is rotatablely moved, affect down at crank pin [20], connecting rod [21] cross bar [22] movable pulley [6], move reciprocatingly, by static pulley [1], make rope hanger do back and forth vertical motion up and down, drive oil pump and carry out oil suction oil extraction work.

Advantage of the present utility model is compared with beam pumping unit, it simple in structure, and size is little, and is in light weight, and performance is good, and technology is simple, can satisfy the using scope of broad stroke, the economical with materials and the energy according to the combined transformation of sheave block;

Avoid the defective of insoluble horse head run-out tolerance and crank price scissors, improved the technical-economic index of sucker-rod pumping equipment effectively; Adjustable triangular support is fixed with movable joint, and support can oppositely reverse during well workover, does not influence operation.Aim at the browpiece fine setting during installation and do not need the complete machine displacement.

Following legend has been described embodiment of the utility model.

Fig. 1 is the utility model vertical profile schematic representation

Fig. 2 is the static pulley organigram

The utility model specifically can implement to make base [14] like this, motor on it [16] is fixed on the motor cabinet [17], link to each other with speed reducer [13] by belt [15], speed reducer is equipped with brake [18], crank [12], the crank top connects counterweight [19], and cross bar [22] joins through connecting rod [21] and crank pin [20], front leg strut has fine setting silk short [8], and front leg strut [7] and two rear support legs [10] are taken out [3] the adjustable triangular support that is composed of a fixed connection with pin.Link to each other with base [14] with movable joint [9], [11], the nearly bearing pin [3] in front leg strut [7] upper end has been located hanging head steel [4], cross bar [22] termination connects running block [6], rear support leg [11] connects support static pulley group [1] through bearing pin [3] extended spot, rope hanger [5] one ends are fixed on hanging head steel [4], walk around fixed wheel [2], sagging through deciding slide-bar group [1] again through running block [6], its end is equipped with transverse slat and links to each other with the oil pump bar with tapered sleeve, the movable pulley vertical motion about static pulley becomes sucker rod that back and forth moves up and down, carry out oil suction and oil extraction work by outstanding rope.

When the installation adjustment, to aim at well head and adjust a silk square [8], static pulley [1] just can be shifted front and back, and rope hanger center and sucker rod center are overlapped; During well workover, extract the pin of movable joint [9] out, support just can be around the reverse rear and do not influence work-over operation of movable joint [11] and bearing pin [3].
