Description

TECHNICAL FIELD

[0001] The utility model relates to the field of surface well pumping unit, especially to a self-adjusting deflection pumping unit rope hanger and beam pumping unit. BACKGROUND

[0002] The rope hanger is used for connecting the horse head and the polished rod. It is composed of a jump-preventing baffle, a load hanging plate and fasteners. The jump-preventing baffle includes a dynamometer chuck and a polished rod righting hemisphere. The load hanging plate is a cuboid structure with a hemispherical polished rod deflection adjusting groove in the middle and U-shaped grooves at both ends for suspending the rope.

[0003] As shown in Figure 1 , the load hanging plate 102 of the rope hanger often deflects during use due to the lack of effective constraints. The bending of the rope 101 at the stress uneven and the cutting of the rope by the inner edges of the U-shaped slot 103 end face cause 80% of the rope 101 to break and consume at the root.

[0004] To solve the above problems, the Chinese utility model patent with the authorization announcement date of June 23, 2023 (CN219241856U) discloses a rope hanger load hanging plate structure, as shown in Figure 2 and Figure 3 , which includes a universal hemisphere 202, a polished rod ball head 203, a rope ball groove 206 and a rope head ball groove 209. The load hanging plate 201 has a first side opening 207 and a second side opening 205 on the left and right sides, respectively. The top of the first side opening 207 and the second side opening 205 is provided with a rounded side edge 204. The bottom of the load hanging plate 201 is provided with a rope head ball groove 209. The universal hemisphere has an opening groove 208. The universal hemisphere 202 is installed in the rope head ball groove 209. During the operation of the pumping unit, the universal hemisphere 202 can rotate in the rope head ball groove 209. Through the polished rod ball head 203 and the two universal hemispheres 202, it can automatically adjust the deflection to center the rope in the rope hanger, reduce the rope loss, prolong the service life of the rope and reduce the production cost.

[0005] However, the universal hemisphere 202 designed in this scheme is too large compared to the ball groove 209 at the lower end of the rope hanger, causing the universal hemisphere 202 to have an arc-shaped side exposed to the external environment after assembly. The pumping unit is often used in harsh environments, and after a long period of work, the exposed part of the universal hemisphere 202 is easily eroded by the external harsh environment, and impurities may accumulate at the exposed position, causing damage to the ball groove 209 when the universal hemisphere 202 moves in the ball groove 209.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] The specific implementation method of the self-adjusting deflection oil pumping unit suspension rope device of this utility model is as follows:

[0035] The concept of this utility model is that, compared with the prior art, the height of the universal hemisphere 304 of this utility model is smaller than the depth of the ball groove 307 at the lower end of the suspension rope fixing hole 306. The universal hemisphere 304 will be completely protected in the ball groove 307 at the lower end of the suspension rope fixing hole 306. During use, there are no exposed parts for most of the time, which can avoid corrosion from wind, sand, oil and other environmental factors, and also prevent sand and dust from adhering to its surface. This can avoid or slow down the damage to the universal hemisphere 304 and the ball groove 307, and solve the problem that the existing suspension rope device is easily corroded by the outside world and the problem of damage to the ball groove 307.

[0036] like Figures 4-8 As shown, based on the above-mentioned inventive concept, a self-adjusting deflection pumping unit suspension device is designed. The suspension device includes a load hanging plate 302, a smooth rod ball groove 305 in the middle of the load hanging plate 302, and suspension rope fixing holes 306 at both ends. A universal hemisphere 304 is installed inside the ball groove 307 at the lower end of the suspension rope fixing hole. The universal hemisphere 304 will be completely protected in the ball groove 307 at the lower end of the suspension rope fixing hole.

[0037] like Figure 5As shown, the suspension rope fixing hole 306 is provided at both ends of the load hanging plate 302, and a reverse tapered ball groove 308 is provided at the upper end of the suspension rope fixing hole 306, so that the suspension rope fixing hole 306 has a whole hourglass shape. The suspension rope fixing hole 306 is designed to have a short axial length of the central hole 309, and the shorter the axial length of the central hole 309, the less likely the suspension rope 301 is to contact the suspension rope fixing hole 306, thereby better protecting the suspension rope 301.

[0038] Specifically, the upper end of the suspension rope fixing hole 306 is designed to be reverse tapered, so that the suspension rope does not directly contact the suspension rope fixing hole 306 during deflection, thereby achieving the purpose of protecting the suspension rope 301 and reducing loss. However, the upper end of the suspension rope fixing hole 306 does not necessarily have to be designed to be reverse tapered, and shapes such as semicircles can also be used, as long as they can reduce the contact area with the suspension rope.

[0039] As shown in the figure, Figure 5 The load hanging plate 302 is provided with a hanging plate opening at both ends for the suspension rope to enter the corresponding suspension rope fixing hole 306 in the radial direction.

[0040] Specifically, the suspension rope 301 can be installed through the opening side of the load hanging plate 302, so that the suspension rope 301 is easier to install or replace. The width of the two side openings is greater than the diameter of the suspension rope 301, and the inner surface of the two side openings of the load hanging plate 302 is as smooth as possible, so that the suspension rope 301 is less likely to be scratched during installation, thereby better protecting the suspension rope 301, reducing the loss of the suspension rope 301, and improving work efficiency.

[0041] As shown in the figure, Figure 8 A universal hemisphere 304 is designed, and a centering groove 310 for centering the rope head of the suspension rope 301 is provided on the lower side of the bottom of the universal hemisphere 304.

[0042] Specifically, the suspension rope 301 of the suspension rope device is installed at the suspension rope head 303 of the suspension rope device, and the suspension rope head 303 is mostly a lead head. The suspension rope head 303 of the suspension rope device has a stepped circular sleeve structure, and the radius of the upper stepped circular sleeve is smaller than the radius of the lower stepped circular sleeve. The suspension rope head 303 of the suspension rope device can cooperate with the centering groove 310 at the bottom of the universal hemisphere to keep the suspension rope root fixed in the suspension rope device and prevent it from shaking, thereby protecting the suspension rope root of the suspension rope device, reducing the loss of the suspension rope 301, and improving work efficiency.

[0043] As shown in the figure, Figure 8 One side of the universal hemisphere 304 is provided with a hemisphere opening in communication with the suspension rope through hole, so that the suspension rope 301 enters the suspension rope through hole in the radial direction.

[0044] Specifically, the universal hemisphere 304 is provided with an opening on one side, so that the installation and replacement of the suspension rope 301 become more simple. The width of the side opening of the universal hemisphere 304 also needs to be greater than the diameter of the suspension rope 301. The optimal solution is that the width of the side opening of the universal hemisphere 304 is consistent with the width of the side opening of the load hanging plate 302 and is greater than the diameter of the suspension rope 301. However, the width of the side opening of the universal hemisphere 304 is not limited to being consistent with the width of the side opening of the load hanging plate 302. As long as the width of the side opening of the universal hemisphere 304 is greater than the diameter of the suspension rope 301, the implementation can be adopted.

[0045] The specific implementation of the beam type oil pumping unit of the utility model is as follows:

[0046] The innovation of the beam type oil pumping unit of the utility model lies in that a self-adjusting deflection oil pumping unit suspension rope device of the utility model is adopted, other structures are prior art, the structure of the suspension rope device can refer to the specific implementation of the above suspension rope device, and details are not described herein.
