Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for oil pumping units, and in particular to a portable oil pumping unit unloading bracket with a foldable base. Background Technology

[0002] Pumping units are the core power equipment in oilfield development. During their installation, maintenance, or unloading, specialized unloading supports are usually required to provide stable and reliable temporary support. To ensure sufficient load-bearing capacity and structural stability, most existing unloading supports adopt rigid structures that are integrally welded or spliced ​​from large profiles. Although this design is sturdy, it also results in huge overall size and weight, making it extremely inconvenient to transport between different well sites. This not only occupies a lot of transportation space and increases logistics costs, but also requires a lot of manpower and resources for on-site handling and deployment.

[0003] To address transportation issues, some modular support structures exist, requiring on-site assembly. However, these structures typically rely on numerous bolts and nuts for fastening. In field operations, aligning components, inserting bolts, and tightening them one by one using various tools are extremely cumbersome and time-consuming, especially in harsh environments. This results in low installation and disassembly efficiency, impacting the overall construction progress.

[0004] In summary, existing pumping unit unloading supports generally suffer from a contradiction between portability and ease of installation in their structural design. Integrated structures are inconvenient to transport, while modular structures are too cumbersome to install. This leads to core problems in practical applications, such as high transportation costs, long deployment cycles, and low operational efficiency, making it difficult to meet the requirements of efficient and flexible operations in modern oilfields.

[0005] Therefore, this utility model proposes a portable oil pump unloading bracket with a folding base to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing portable oil pumping unit unloading brackets with foldable bases, such as large size and inconvenient transportation due to fixed structure, as well as cumbersome on-site installation and disassembly steps, reliance on multiple tools, and low work efficiency, this utility model aims to provide a portable oil pumping unit unloading bracket with foldable base that has an improved structure and can effectively solve the above problems.

[0007] This utility model provides a portable oil pump unloading bracket with a folding base, comprising: a first base, a bracket body with a connecting block fixedly connected to the bottom of the bracket body, a second base, a folding component, and a connecting component.

[0008] One end of the first base is rotatably connected to one end of the second base via a folding assembly. This structure allows the first and second bases to be folded together to reduce their storage volume, or unfolded together to form a stable support base.

[0009] Furthermore, the connecting component is fixed to the first base. The connecting component includes a fixing block, in which a second threaded post is rotatably disposed. At the same time, two connecting posts are slidably disposed in the fixing block. A transmission connection is formed between the second threaded post and the two connecting posts. By rotating the second threaded post, the two connecting posts can be driven to slide towards each other to clamp the connecting block located between them, or slide apart to release the connecting block, thereby realizing the quick fixing and separation between the bracket body and the base.

[0010] Preferably, the folding assembly includes a pivot and a first threaded post. The pivot is pivotally connected between the first base and the second base, and the first threaded post is threadedly connected to the first base and used to lock the first base and the second base in the unfolded state.

[0011] Preferably, both the first base and the second base have movable slots, and the folding assembly further includes a connecting plate, which is fixed to the rotating shaft.

[0012] Preferably, each of the connecting posts has a second limiting post fixed at one end facing the connecting block. The second limiting post is used to directly abut against the connecting block to provide a more stable clamping effect with a larger contact area.

[0013] Preferably, a first limiting post is also fixedly connected inside the fixing block. The first limiting post is arranged parallel to the axis of the second threaded post and is used to limit the axial displacement of the second threaded post, so as to ensure that its rotational motion can be stably converted into the linear motion of the connecting post.

[0014] Preferably, the fixing block has an operating through hole, and one end of the second threaded post has a driving part adapted to the internal hex wrench, and the driving part is coaxially opposite to the operating through hole, which facilitates quick operation using tools.

[0015] Preferably, the axis of the first threaded post is perpendicular to the axis of the rotating shaft, and the end of the first threaded post is used to abut or disengage from the second base to lock or unlock the unfolded state.

[0016] Preferably, the two connecting posts slide along a straight line parallel to the length direction of the first base to ensure smooth clamping and centering.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing oil pump unloading brackets being bulky and inconvenient to transport due to their fixed structure by setting up a first base and a second base that can be rotatably connected to each other, and using a folding component to realize their unfolding locking and folding storage. It achieves the technical effect of reducing the transportation and storage volume of the equipment, improving portability and reducing logistics costs.

[0018] 2. This utility model, by setting a connecting component, uses the rotating second threaded column to drive the two connecting columns to move towards or away from each other, so as to clamp or loosen the connecting block at the bottom of the bracket. This solves the problem that the existing bracket installation and disassembly steps are cumbersome, rely on multiple tools, and are time-consuming and labor-intensive. It achieves the technical effect of quickly completing the installation and disassembly with only a single tool, simplifying the operation steps and improving the efficiency of on-site construction.

[0019] 3. This utility model solves the problem of low efficiency in the entire process from transportation to installation of traditional brackets during on-site deployment by combining folding components with quick-connect components. It enables the brackets to be quickly unfolded, deployed, and installed and fixed, shortening the overall work preparation time and enhancing the rapid response and deployment capabilities of the equipment.

[0022] 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.

[0023] Please refer to Figures 1 to 4 This utility model provides a portable pumping unit unloading bracket with a foldable base, which aims to solve the problems of existing pumping unit unloading brackets having a fixed structure, large size leading to inconvenient transportation, and cumbersome and inefficient installation and disassembly steps.

[0024] like Figure 1 As shown, the portable oil pump unloading bracket includes a first base 1, a bracket body 2, a second base 4, a folding assembly 5, and a connecting assembly 6. A connecting block 3 is fixedly connected to the bottom of the bracket body 2. One end of the first base 1 is rotatably connected to one end of the second base 4 through the folding assembly 5, so that the first base 1 and the second base 4 can be folded or unfolded relative to each other. The connecting assembly 6 is fixed to the first base 1 and is used to clamp or loosen the connecting block 3, thereby realizing the quick installation and disassembly of the bracket body 2 and the first base 1. Specifically, the connecting assembly 6 includes a fixing block 601, a second threaded post 602 is rotatably disposed in the fixing block 601, and two connecting posts 604 are slidably disposed in the fixing block 601. The second threaded post 602 is connected to the two connecting posts 604 in a transmission manner. When the second threaded post 602 rotates, it can drive the two connecting posts 604 to slide towards or away from each other.

[0025] To solve the above-mentioned technical problems, a specific foldable rotating connection structure is formed between the first base 1 and the second base 4 through the folding component 5. This structure allows the base to be unfolded during use to ensure stability and folded during transportation to reduce volume.

[0026] Please refer to Figure 2 and Figure 3The folding assembly 5 includes a pivot 501, a first threaded post 502, a connecting plate 503, and movable slots 504 formed in the first base 1 and the second base 4. The pivot 501 is pivotally connected between the first base 1 and the second base 4, providing a pivot center for the relative rotation of the first base 1 and the second base 4. Movable slots 504 are formed in the ends of both the first base 1 and the second base 4. The connecting plate 503 is fixed to the pivot 501 and is used to provide structural reinforcement and guidance during rotation. The first threaded post 502 is threadedly connected to the first base 1, and its axis is perpendicular to the axis of the pivot 501. When the first base 1 and the second base 4 are fully unfolded to form a flat state, the first threaded post 502 is tightened so that its end abuts against the second base 4, thereby firmly locking the two bases and forming a stable and reliable overall base platform. When folding is required, the first threaded post 502 is loosened so that its end is disengaged from the second base 4, thereby releasing the lock. At this time, the first base 1 can rotate relative to the second base 4 around the pivot 501, realizing the folding of the base.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 4 To achieve a more stable and reliable clamping of the connecting block 3, each connecting post 604 has a second limiting post 605 fixed at one end facing the connecting block 3. The second limiting post 605 is used to directly abut against the connecting block 3, thereby increasing the contact area to disperse stress and enhance the firmness of the fixation.

[0028] As another preferred implementation, refer to the following: Figure 4 The fixing block 601 is also fixedly connected with a first limiting post 603. The first limiting post 603 is set parallel to the axis of the second threaded post 602 and is used to limit the axial displacement of the second threaded post 602. This structure ensures that the second threaded post 602 will not move axially when rotating, thereby ensuring that its rotational motion can be efficiently converted into the linear sliding of the connecting post 604. In a specific arrangement, the two connecting posts 604 slide along a straight line parallel to the length direction of the first base 1. This linear sliding method ensures that the clamping force on the connecting block 3 is stable and centered.

[0029] As another preferred embodiment, for ease of operation, please refer to... Figure 4 The fixed block 601 has an operating through hole, and one end of the second threaded post 602 has a drive part that is compatible with the internal hex wrench. The drive part is coaxial with the operating through hole, and the operator can pass the internal hex wrench through the operating through hole and directly engage with the drive part to perform a rapid rotation operation.

[0030] As a further limitation on folding component 5, please refer to Figure 3The axis of the first threaded post 502 is perpendicular to the axis of the rotating shaft 501. The end of the first threaded post 502 is used to abut or disengage from the second base 4. This vertically arranged abutment-type locking structure is simple and effective, and can provide a strong locking force to prevent the base from accidentally folding when under load.

[0031] The working principle of this portable oil pump unloading bracket with a folding base is as follows: During transportation or storage, the first base 1 and the second base 4 are folded by the folding assembly 5, resulting in a small volume. When on-site deployment is required, first loosen the first threaded post 502 to separate it from the second base 4. Then, rotate the first base 1 and the second base 4 around the pivot 501 to unfold them into a flat state. During this process, the connecting plate 503 rotates in the movable groove 504. Finally, tighten the first threaded post 502 so that its end abuts against and locks the second base 4, thereby quickly forming a large-area stable base.

[0032] After the base is unfolded and locked, the connecting block 3 at the bottom of the bracket body 2 is placed in the predetermined position of the connecting component 6 on the first base 1. An Allen wrench is used to rotate through the operating through hole on the fixing block 601 and cooperate with the driving part of the second threaded post 602. The second threaded post 602 rotates purely under the limiting action of the first limiting post 603 and drives the two connecting posts 604 to slide towards each other until the second limiting post 605 at the end of the connecting post 604 firmly clamps the connecting block 3. When disassembling, the second threaded post 602 can be rotated in the opposite direction. Through the synergistic effect of the folding component 5 and the connecting component 6, this utility model solves the problems of the existing pumping unit unloading bracket being large in size, inconvenient to transport, and cumbersome and time-consuming to install and disassemble on site.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
