the utility model relates to an oil recovery equipment technical field, concretely relates to pumping unit accessory.
Background art:
the rope hanger is a pumping unit accessory rope hanger, the function of the rope hanger is to connect a hair braid on a horsehead of a pumping unit and a pumping rod, the rope hanger has the functions of connection, shock absorption and eccentric wear prevention, the main reason for eccentric wear is that the rope hanger and a well head are inevitably subjected to deviation during installation, the deviation is eliminated at present mainly by arranging a joint capable of rotating along the deviation direction on the well head, and the mode only can reduce the eccentric wear phenomenon of the pumping rod and cannot radically eliminate the eccentric wear phenomenon.
The utility model has the following contents:
in order to solve the problem, the utility model aims at providing an oil pumping unit accessory.
The technical scheme of the utility model is that: pumping unit accessory, including the clamp, the clamp is the half body structure, and two clamps pass through the bolt-up on the sucker rod, and the mounted position of fastening on the sucker rod, the step axle that two clamp lower parts formed passes through thrust bearing and connects the top shoe, and the top shoe passes through vertical dovetail and connects the bottom shoe, and the bottom shoe passes through horizontal dovetail and connects the fixed block, and the fixed block lower part passes through belleville spring connection supporting seat, and the supporting seat both sides are equipped with the lug and connect the hair pigtail.
The sucker rod comprises an upper sliding block, a lower sliding block, a fixing block and a supporting seat, wherein the upper sliding block, the lower sliding block, the fixing block and the supporting seat are all provided with center holes at the passing positions of the sucker rod, and the diameter of each center hole is larger than the offset between the designed sucker rod rope hanger and a well head.
The diameter of the upper part of the disc spring is small, the diameter of the lower part of the disc spring is large, and the screw pitches of the disc springs are arranged from top to bottom in a small-to-large mode.
The upper sliding block, the lower sliding block and the fixing block are all made of stainless steel.
The roughness of the guide joint surface of the longitudinal dovetail groove and the transverse dovetail groove is 0.08-0.12 mm.
The utility model discloses following beneficial effect has: the upper sliding block, the lower sliding block and the fixed block which are made of stainless steel can prevent the corrosion under the outdoor environment, the high-precision roughness can reduce the friction force of the joint surface of the dovetail grooves, the moving resistance is reduced, the clamp is fixedly connected with the sucker rod, a thrust bearing is arranged between the clamp and the upper sliding block to solve the rotation problem of the sucker rod, the longitudinal dovetail groove and the transverse dovetail groove are arranged to be used for connecting the sucker rod, the clamp, the supporting seat and the hair braid are connected, when the deviation is generated between the rope hanger and the well head, the transverse dovetail groove and the longitudinal dovetail groove generate displacement, the sucker rod on the rope hanger is always aligned with the well head, the eccentric wear problem of the sucker rod is solved, and the butterfly spring with the elastic force.
Description of the drawings:
figure 1 is a schematic structural diagram of the present invention,
FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
fig. 3 is a cross-sectional view B-B of fig. 1.
In the figure, 1-a hoop, 2-a thrust bearing, 3-an upper slide block, 4-a lower slide block, 5-a disc spring, 6-a support seat, 7-a sucker rod, 8-a central hole, 9-a transverse dovetail groove, 10-a longitudinal dovetail groove, 11-a lifting lug and 12-a fixed block.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
shown by figure 1 in combination with figures 2 ~ 3, beam-pumping unit accessory, including clamp 1, clamp 1 is two half body structures, two clamp 1 pass through the bolt-up on sucker rod 7, the mounted position of fastening on sucker rod 7, the step axle that two clamp 1 lower parts formed passes through thrust bearing 2 and connects slider 3, slider 4 is connected down through vertical dovetail 10 to slider 3, slider 4 is connected fixed block 12 through horizontal dovetail 9, disk spring 5 joint support seat 6 is passed through to fixed block 12 lower part, 6 both sides of support seat are equipped with lug 11 and connect the hair pigtail.
