Description

Technical Field

[0001] This utility model relates to the field of hydraulic rod stable placement technology, specifically to a hydraulic rod anti-detachment suspension device. Background Technology

[0002] In oil extraction, the sucker rod is a key component connecting the surface pumping unit and the downhole pump. Its main functions are to withstand alternating loads, adapt to long-term reciprocating motion, and be corrosion-resistant so that it can be used in the downhole environment containing corrosive media.

[0003] Since oil development is a cyclical process, sucker rods are subjected to heavy loads and require maintenance. During maintenance, clamping rings are usually used to help stabilize the sucker rods. This method can prevent the rods from shaking to some extent. However, the shape of the sucker rod is not straight and its mass distribution is uneven. The clamping rings cannot meet the long-term suspension requirements of the sucker rod. Therefore, a deflectable and stable device should be used to meet the requirement of preventing the sucker rod from detaching during maintenance. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hydraulic rod anti-detachment suspension device, which can effectively solve the problem of suspension instability caused by uneven hydraulic rod mass in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a hydraulic rod anti-detachment suspension device, including a base, the base is fitted with an inner component, the inner component is provided with a hydraulic rod, and the hydraulic rod is fitted with a suspension component and a reinforcing component;

[0007] The suspension assembly includes a locking ring sleeved on the outer surface of the hydraulic rod, with a mating buckle between two locking rings. An ear plate seat is fitted onto the upper surface of the locking ring, and a release element is provided on the side of the ear plate seat. The release element includes a long connecting rod rotatably connected to the ear plate seat. A shaft is rotatably sleeved on the inner side of the long connecting rod, and a push frame is fixedly connected to the outer surface of the shaft. A square internal tooth is movably engaged on the side of the push frame, and a straight plate is fitted onto the side of the square internal tooth.

[0008] Furthermore, the inner component includes a rubber plug ring, which is sleeved on the outer surface of the oil rod. A tension block is snapped onto the top of the rubber plug ring, and the plurality of rubber plug rings are arranged in a straight line.

[0009] Furthermore, a spring is adapted to be installed on the outer side of the straight plate, and an inner bending strip is fixedly connected to the end face of the spring. The inner bending strip is an integrally formed curved elastic strip, and one end of the inner bending strip is hinged to the surface of the long connecting rod. The reinforcing assembly also includes a reinforcing rod, which is rotatably installed on the side of the long connecting rod.

[0010] Furthermore, the number of the slow-release components is two sets, and the two sets of slow-release components are symmetrically arranged on the outer side of the oil rod.

[0011] Furthermore, the maximum deflection angle of the long connecting rod is an acute angle, and the rotating parts of the long connecting rod and the shaft are coated with grease.

[0012] Furthermore, there are two inner bends, and the top end faces of the two inner bends are provided with wrapping blocks.

[0013] Furthermore, the wrapping block is an integrally formed tightening block, and the wrapping block is always wrapped around the outer surface of the oil rod during the tightening process.

[0014] Furthermore, the center of the rubber stopper ring is aligned with the center of the oil rod.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] First, the internal components allow for more comprehensive coverage of the hydraulic rod, improving its suspension stability. A locking ring on the outer surface of the hydraulic rod allows it to be directly locked in position, mitigating suspension sway caused by uneven mass distribution. Next, a shaft is installed inside the long connecting rod, allowing it to rotate continuously. The hydraulic rod's weight causes the shaft to droop, offsetting gravity with rotational force. The shaft's wide rotation range meets the suspension requirements of different areas. Furthermore, a push frame is installed on the shaft's surface, engaging with the internal teeth of the block. This ensures stable engagement of different areas of the hydraulic rod during suspension. The unique block structure of the internal teeth provides significant support to the push frame, further ensuring static stability during suspension and achieving the hydraulic rod's anti-detachment function.

[0018] Second, by using the combination of the rubber plug ring and the tension block, the bottom of the oil rod contacts the rubber plug ring first. Then, the oil rod continuously adjusts its position, and the tension block, affected by this, drives the other rubber plug rings to stretch, which greatly expands the wrapping area of ​​the rubber plug ring, effectively reduces the bottom sway of the oil rod, and achieves the stability of the bottom suspension.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] See attached document Figure 1-5 A hydraulic rod anti-detachment suspension device includes a base 1, an inner connection component 2, a hydraulic rod 3 inside the inner connection component 2, and a suspension component 4 and a reinforcing component 5.

[0029] The suspension assembly 4 includes a locking ring 41 sleeved on the outer surface of the hydraulic rod 3. A mating buckle 42 is provided between the two locking rings 41. An ear plate seat 43 is adapted to be installed on the upper surface of the locking ring 41. A release element 44 is provided on the side of the ear plate seat 43. The release element 44 includes a long connecting rod 441 rotatably connected to the ear plate seat 43. A shaft 442 is rotatably sleeved on the inner side of the long connecting rod 441. A push frame 443 is fixedly connected to the outer surface of the shaft 442. A square internal tooth 45 is movably engaged on the side of the push frame 443. A straight plate 46 is adapted to be installed on the side of the square internal tooth 45.

[0030] By incorporating the inner component 2, the hydraulic rod 3 is more fully covered, which helps maintain its suspension stability. A locking ring 41 is fitted onto the outer surface of the hydraulic rod 3, allowing it to be directly locked in place, thus mitigating suspension sway caused by uneven mass distribution. Next, a shaft 442 is installed inside the long connecting rod 441, allowing it to rotate continuously. The hydraulic rod 3's weight causes the shaft 442 to droop, offsetting the gravity with rotational force. The shaft 442 has a large rotation range, meeting the suspension requirements of different areas of the hydraulic rod 3. Furthermore, a push frame 443 is installed on the surface of the shaft 442, engaging with the internal teeth 45. This ensures stable engagement of different areas of the hydraulic rod 3 during suspension. The unique block structure of the internal teeth 45 also provides significant support to the push frame 443, ensuring static stability of the hydraulic rod 3 during suspension and achieving its anti-detachment function.

[0031] The inner component 2 includes a rubber plug ring 21, which is sleeved on the outer surface of the oil rod 3. A tension block 22 is snapped onto the top of the rubber plug ring 21, and the multiple rubber plug rings 21 are arranged in a straight line.

[0032] By cooperating with the rubber plug ring 21 and the tension block 22, the bottom of the oil rod 3 first contacts the rubber plug ring 21. Then, the oil rod 3 continuously adjusts its position. The tension block 22 is affected by this and drives the other rubber plug rings 21 to stretch, which greatly expands the wrapping area of ​​the rubber plug ring 21, effectively reduces the bottom shaking of the oil rod 3, and achieves the stability of the bottom suspension.

[0033] A spring 47 is fitted to the outer side of the straight plate 46. An inner bending strip 52 is fixedly connected to the end face of the spring 47. The inner bending strip 52 is an integrally formed curved elastic strip, and one end of the inner bending strip 52 is hinged to the surface of the long connecting rod 441. The reinforcing component 5 also includes a reinforcing rod 51, which is rotatably mounted on the side of the long connecting rod 441.

[0034] By cooperating with the inner bending strip 52 and the spring 47, the long connecting rod 441 is elastically supported on one side of its surface when it rotates. The reinforcing rod 51 installed on the other side of the long connecting rod 441 allows the bottom of the long connecting rod 441 to be rigidly supported when it rotates, and the top can deflect over a large range. This can absorb a large amount of shaking in the middle area of ​​the hydraulic rod 3, thereby ensuring the suspension stability of the hydraulic rod 3.

[0035] There are two sets of slow-release components 44, which are symmetrically arranged on the outer side of the oil rod 3. The maximum deflection angle of the long connecting rod 441 is an acute angle, and the rotating parts of the long connecting rod 441 and the shaft 442 are coated with grease.

[0036] The symmetrical arrangement of the two sets of slow-release components 44 makes the suspension effect on the hydraulic rod 3 more uniform, which helps to reduce the tilting and swaying of the hydraulic rod 3.

[0037] There are two inner bending strips 52. The top end face of the two inner bending strips 52 is provided with wrapping blocks 53. The wrapping blocks 53 are integrally formed tightening blocks, and the wrapping blocks 53 are always wrapped around the outer surface of the oil rod 3 during the tightening process.

[0038] The inner bend 52 and the wrapping block 53 are designed to work together to pull the wrapping block 53. After the wrapping block 53 is tightened, it continuously wraps around the outer surface of the oil rod 3, reducing the suspension sway of the top area of ​​the oil rod 3.

[0039] The center of the rubber stopper ring 21 and the center of the oil rod 3 are aligned in a straight line.

[0040] Working principle: After the oil rod 3 is removed from the pumping unit, it first falls into the inner cavity of the rubber plug ring 21. Then, the locking ring 41 is installed on the outer surface of the middle area of ​​the oil rod 3. The two locking rings 41 are fastened and aligned with the butt buckle 42 for the stability of the middle area of ​​the oil rod 3.

[0041] It is particularly noteworthy that the hydraulic rod 3 wobbles due to its excessive weight. With the help of an external crane, the hydraulic rod 3 continues to be pressed into the rubber plug ring 21. During this process, the long connecting rod 441 will drive the push frame 443 to deflect and drive the reinforcing rod 51 to deflect synchronously, thus achieving its own hinge support. Then, the push frame 443 will continue to slide along the inner side of the straight plate 46 and engage with the inner teeth 45 of the block. The engagement movement will significantly consume the deflection force of the long connecting rod 441, making the long connecting rod 441 gradually stable, thereby providing rigid support for the hydraulic rod 3 and achieving the effect of suspension stability.

[0042] Then, the long connecting rod 441 pulls the inner bending strip 52, which further tightens the wrapping block 53, so that the wrapping block 53 is stably wrapped on the outer surface of the oil rod 3, thus achieving the function of preventing detachment.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
