Description

Technical Field

[0001] This utility model relates to the field of sucker rod storage technology, and in particular to an oilfield sucker rod storage rack. Background Technology

[0002] In oilfield development operations, sucker rods are key components connecting the pumping unit and the pump. They need to be frequently pulled out to maintain oil well production. Since a single sucker rod is usually 6-9 meters long and weighs tens of kilograms, the safety, convenience, and space utilization of its storage and transportation directly affect oilfield production efficiency and operating costs.

[0003] In existing technologies, some oilfield sucker rod storage racks are based on modular positioning and adaptive support design: the main frame is constructed with high-strength steel, and each layer is equipped with movable V-shaped support blocks distributed along the length direction. The spacing of the support blocks is adjusted by sliding rails to match the placement requirements of sucker rods of different diameters. The support blocks have built-in buffer rubber pads, which not only avoid electrochemical corrosion caused by direct contact between the rod and metal, but also offset the impact caused by slight shaking of the sucker rod through elastic deformation.

[0004] However, in actual use, sucker rods of different lengths need to be stored separately. If the storage racks are incompatible, they can only be piled on the ground or in temporary areas, resulting in a messy situation. When retrieving a sucker rod of a specific length, it is necessary to search for each one individually, which greatly increases the time spent on selection and transportation and slows down the work pace. In response to the above problems, a sucker rod storage rack for oilfields is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an oilfield sucker rod storage rack, which aims to improve the problem that some existing oilfield sucker rod storage racks cannot accommodate sucker rods of different lengths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An oilfield sucker rod storage rack includes a base, with support rods fixedly connected to the top four corners of the base, and storage plates fixedly connected to the outer sides of two support rods on their adjacent sides. A position adjustment mechanism is fixedly connected to the top of the storage plate, and disassembly and assembly mechanisms are slidably connected to the upper and lower ends of the support rods.

[0008] The position adjustment mechanism includes a motor, which is fixedly connected to the outside of the storage plate. A drive rod is fixedly connected to the outside of the motor, and a pulley assembly is fixedly connected to the outside of the drive rod. A driven rod is fixedly connected to the other end of the pulley assembly. A drive plate is fixedly connected to the drive end of the drive rod. Fixed shafts are fixedly connected to the front and rear sides of the drive plate. A follower plate is rotatably connected to the outside of the fixed shafts. A sliding plate is rotatably connected to the outside of the follower plate. A limit assembly is fixedly connected to the top of the storage plate, and an adjustment and clamping assembly is fixedly connected to the top of the sliding plate.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting plate, which is fixedly connected to the top of the storage plate. Limiting blocks are fixedly connected to both the front and rear sides of the limiting plate.

[0011] As a further description of the above technical solution:

[0012] The adjusting clamping assembly includes a through-hole mounting plate, which is externally fixedly connected to the top of the sliding plate. A connecting plate is slidably connected inside the through-hole mounting plate. Multiple mounting plates are fixedly connected to the top of the through-hole mounting plate. Connecting rods are fixedly connected to the top left and right sides of the top of each mounting plate. A rubber ring is fixedly connected to the top of each connecting rod.

[0013] As a further description of the above technical solution:

[0014] The disassembly and assembly mechanism includes a sliding latch rod, which is slidably connected to the outside of the support rod. A cavity is provided on the outside of the support rod, and a limit plate is slidably connected to the outside of the cavity. A return spring is sleeved on the outside of the sliding latch rod.

[0015] As a further description of the above technical solution:

[0016] The limiting plate 2 is fixedly connected to the outside of the sliding rod, and the sliding rod is slidably connected to the inside of the cavity.

[0017] As a further description of the above technical solution:

[0018] A pull plate is fixedly connected to the outside of the sliding lever, and the outside of the pull plate is in contact with the outside of the support rod;

[0019] As a further description of the above technical solution:

[0020] The base is fixedly connected to connecting frames on both the left and right sides of the outside, and a supporting base plate is fixedly connected to the bottom of the connecting frames.

[0021] As a further description of the above technical solution:

[0022] One end of the reset spring is fixedly connected to the outside of the second limiting plate, and the other end of the reset spring is fixedly connected to the inside of the support rod.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the motor drives the active rod, which drives the driven rod through the pulley set, causing the drive plate and follower plate to rotate. This causes the sliding plate to slide on the limiting plate, causing the through hole mounting plate to retract. This allows the sucker rods of different lengths to be placed inside the rubber ring. The limiting block prevents the sliding plate from disengaging. A single motor enables multi-component linkage, automatically adapting to the sucker rod length. The structure is compact, the operation is efficient, and it ensures stable placement of the sucker rod, improving applicability and reliability.

[0025] 2. In this utility model, pulling the pull plate causes the sliding lever to disengage from the storage plate, allowing the storage plate to be quickly removed. During installation, releasing the pull plate causes the return spring to snap back and lock the lever into place, making the operation simple and efficient. No tools are required for efficient disassembly and assembly. The spring assists in securing the lever, facilitating the maintenance and replacement of the storage plate, improving the flexibility of space utilization, and adapting to diverse storage needs.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of an oilfield sucker rod storage rack, comprising a base 1, with support rods 2 fixedly connected to the four corners of the top of the base 1. The base 1 has an overall rectangular structure, and its bottom is fixed to the ground via pre-embedded bolts or a weighted design, providing strong load-bearing capacity and stability. Storage plates 3 are fixedly connected to the outer, adjacent sides of the two support rods 2. The support rods 2 are key components connecting the base 1 and the storage plates 3, providing not only vertical support for the storage plates 3 but also ensuring the structural stability of the entire storage rack through their rigidity, preventing deformation under stress. A position adjustment mechanism is fixedly connected to the top of the storage plate 3. The upper and lower ends of the support rod 2 are slidably connected to a disassembly mechanism. The disassembly mechanism includes a sliding latch 24, which achieves clamping or separation from the storage plate 3 by sliding itself. When the sliding latch 24 is inserted into the mounting hole of the storage plate 3, the storage plate 3 is fixed on the support rod 2. When the sliding latch 24 is pulled out from the mounting hole, the storage plate 3 can be removed from the support rod 2. The operation is simple and convenient. The sliding latch 24 is slidably connected to the outside of the support rod 2. A cavity 25 is opened on the outside of the support rod 2.

[0035] The dimensions of cavity 25 match those of limiting plate 19, ensuring smooth sliding of limiting plate 19 within cavity 25 while limiting its sliding range to prevent it from detaching from cavity 25. Limiting plate 19 is slidably connected to the outside of cavity 25, limiting the sliding stroke of sliding lever 24 and preventing it from completely dislodging from the sliding hole of support rod 2. It also provides a force point for return spring 20, allowing its elastic force to effectively act on sliding lever 24. Return spring 20 is sleeved on the outside of sliding lever 24. When storage plate 3 needs to be disassembled, pulling the handle of sliding lever 24 compresses return spring 20, causing sliding lever 24 to retract into the sliding hole and separate from storage plate 3. The main function of return spring 20 is to provide automatic reset force for sliding lever 24, ensuring it remains locked to storage plate 3 when no external force is applied, thus guaranteeing the stability of storage plate 3 installation.

[0036] The position adjustment mechanism includes a motor 4, which serves as a power source and converts electrical energy into mechanical energy, providing a stable power output for the entire position adjustment mechanism. By precisely controlling the speed and direction of the motor 4, the precise adjustment of the sucker rod storage position can be achieved. The motor 4 is externally fixedly connected to the outside of the storage plate 3. The motor 4 is externally fixedly connected to a drive rod 5. The main function of the drive rod 5 is to transmit the power of the motor 4, converting the rotational motion of the motor 4 into its own rotation, providing power input for subsequent components. The drive rod 5 is externally fixedly connected to a pulley group 10. The main function of the pulley group 10 is to transmit power and adjust the speed through belt drive, transmitting the power of the drive rod 5 to the driven rod 11. At the same time, the difference in the diameter of the pulleys is used to achieve deceleration or acceleration to meet different transmission requirements. The other end of the pulley group 10 is fixedly connected to the driven rod 11. The main function of the driven rod 11 is to receive the power transmitted by the pulley group 10 and transmit it to the drive plate 6, driving the drive plate 6 to rotate synchronously, thus realizing the transmission of power between different components.

[0037] A drive plate 6 is fixedly connected to the drive end of the drive rod 5. The main function of the drive plate 6 is to convert the rotational motion of the drive rod 5 into the swinging motion of the follower plate 8. Its own rotation drives the fixed shaft 7 to perform circular motion, thereby driving the follower plate 8 to move, thus achieving a conversion of motion mode. Fixed shafts 7 are fixedly connected to both the front and rear sides of the drive plate 6. The main function of the fixed shafts 7 is to provide a pivot point for the follower plate 8, allowing it to swing around the fixed shafts 7, converting the circular motion of the drive plate 6 into the reciprocating swinging motion of the follower plate 8, providing power for the linear motion of the sliding plate 9. The fixed shafts 7 are rotatably connected to the outside of... The follower plate 8's main function is to convert the circular motion of the drive plate 6 into the linear motion of the sliding plate 9. When the drive plate 6 rotates, the fixed shaft 7 rotates accordingly, causing the follower plate 8 to swing, which in turn pushes the sliding plate 9 to make linear reciprocating motion under the restriction of the limiting component, thereby achieving position adjustment. The follower plate 8 is externally rotatably connected to the sliding plate 9. The main function of the sliding plate 9 is to make linear reciprocating motion along the top of the storage plate 3 under the push of the follower plate 8, driving the adjusting clamping component to move synchronously, thereby achieving adjustment of the sucker rod storage position, so that the adjusting clamping component can accurately align the sucker rod in different positions.

[0038] A limiting assembly is fixedly connected to the top of the storage plate 3. The limiting assembly includes a limiting plate 17. The main function of the limiting plate 17 is to provide an installation base for the limiting block 18 and to initially limit the movement range of the sliding plate 9, preventing the sliding plate 9 from slipping off the edge of the storage plate 3. The limiting plate 17 is externally fixedly connected to the top of the storage plate 3. Limiting blocks 18 are fixedly connected to the front and rear sides of the limiting plate 17 to further limit the movement trajectory of the sliding plate 9, ensuring that the sliding plate 9 can only move in a straight line. At the same time, it provides a buffer when the sliding plate 9 moves to its limit position to avoid collision and damage with other components. An adjusting clamping assembly is fixedly connected to the top of the sliding plate 9. The adjusting clamping assembly includes a through-hole mounting plate 12. The main function of the through-hole mounting plate 12 is to provide a sliding guide for the connecting plate 13 and a mounting base for the mounting plate 14, connecting the various components of the adjusting clamping assembly into a whole. The external of the through-hole mounting plate 12 is fixedly connected to the outer top of the sliding plate 9. The internal of the through-hole mounting plate 12 is slidably connected to the connecting plate 13. The main function of the connecting plate 13 is to slide along the through hole of the through-hole mounting plate 12 when the rubber ring 16 is squeezed by external force, and to transmit the external force to the rubber ring 16, so that the rubber ring 16 produces elastic deformation, thereby achieving flexible clamping of the sucker rod and avoiding damage to the surface of the sucker rod. Multiple mounting plates 14 are fixedly connected to the top of the through-hole mounting plate 12. The main function of the mounting plates 14 is to provide an installation position for the connecting rod 15.

[0039] The connecting rod 15 and the rubber ring 16 are fixed to the top of the through-hole mounting plate 12 to ensure the structural stability of the adjusting clamping assembly. The connecting rod 15 is fixedly connected to the top left and right sides of the mounting plate 14. The main function of the connecting rod 15 is to connect the mounting plate 14 and the rubber ring 16, transfer the supporting force of the mounting plate 14 to the rubber ring 16, and provide a fixing point for the rubber ring 16 to ensure that the rubber ring 16 can maintain a stable position when clamping the sucker rod. The top of the connecting rod 15 is fixedly connected to the rubber ring 16. The main function of the rubber ring 16 is to flexibly clamp the sucker rod through its own elastic deformation. When the sucker rod is put into the rubber ring 16, the rubber ring 16 will generate elastic deformation, tightly wrap the sucker rod, provide sufficient friction and clamping force, prevent the sucker rod from shaking or falling during storage, and avoid scratches or indentations on the surface of the sucker rod.

[0040] Reference Figures 3 to 5 The limiting plate 29 is externally fixedly connected to the outside of the sliding latch 24. The sliding latch 24 is externally slidably connected to the inside of the cavity 25. By sliding the sliding latch 24, its end can extend or retract into the cavity 25, thereby achieving clamping or separation with the storage plate 3, facilitating the installation and disassembly of the storage plate 3. A pull plate 21 is externally fixedly connected to the sliding latch 24. The outside of the pull plate 21 contacts the outside of the support rod 2. Connecting brackets 22 are fixedly connected to the left and right sides of the base 1. The main function of the connecting brackets 22 is to connect the base 1 and the support base plate 23, and to support the base 1. The supporting force of the base plate 23 is transferred to the base 1, which enhances the connection stability between the base 1 and the ground and prevents the base 1 from tilting due to uneven force. The outer bottom of the connecting frame 22 is fixedly connected to the supporting base plate 23. The supporting base plate 23 can increase the contact area with the ground and distribute the weight of the storage rack and the load of the sucker rod more evenly to the ground, further improving the overall stability of the storage rack and preventing the storage rack from sinking into the ground when storing a large number of sucker rods. One end of the return spring 20 is fixedly connected to the outside of the limit plate 2 19, and the other end of the return spring 20 is fixedly connected to the inside of the support rod 2.

[0041] Working principle: By starting the motor 4, the motor 4 drives the active rod 5 to rotate. Under the action of the active rod 5, the active rod 5 drives the driven rod 11 to rotate through the pulley group 10. Then, the active rod 5 and the driven rod 11 drive the drive plate 6 to rotate. Under the action of the drive plate 6, the drive plate 6 drives the follower plate 8 to rotate through the fixed shaft 7. Under the action of the follower plate 8, the follower plate 8 can drive the sliding plate 9 to slide outside the limit plate 17. Then, the sliding plate 9 can drive the through hole mounting plate 12 to slide. Then, the connecting plate 13 inside the through hole mounting plate 12 can retract. Then, sucker rods of different lengths can be placed inside the rubber ring 16. Because of the limit block 18, the sliding plate 9 will not detach from the outside of the limit plate 17 during the movement.

[0042] When disassembling and assembling the storage plate 3, by pulling the pull plate 21, the pull plate 21 can drive the limiting plate 19 to slide inside the cavity 25 through the sliding latch 24. Then, the limiting plate 19 can squeeze the return spring 20, which can then separate the sliding latch 24 from the outside of the storage plate 3, and the storage plate 3 can be taken out from the outside of the support rod 2. When installing the storage plate 3, by releasing the pull plate 21, the return spring 20 will rebound, which can then lock the sliding latch 24 into place with the storage plate 3, thus realizing the disassembly and assembly of the storage plate 3.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
