Abstract
Description
Technical Field
[0001] This utility model relates to the field of downhole single-column lifting technology, and in particular to an auxiliary device for downhole single-column lifting, specifically a downhole single-column vertical lifting device. Background Technology
[0002] Single-unit columns are common support devices in downholes, and lifting them is one of the most common operations. Common lifting methods involve two workers carrying them on their shoulders or multiple workers working together to lift them by binding them with wire. When a single-unit column tilts, multiple workers are needed to forcefully lift and straighten it. However, due to the weight of the single-unit column and the lack of a lifting point, lifting is difficult, resulting in low efficiency, high labor intensity for workers, and a low safety factor. Summary of the Invention
[0003] In order to solve the problem of difficult lifting of single-unit columns in wells, this utility model provides a new downhole single-unit column vertical lifting device.
[0004] This utility model is achieved using the following technical solution: A downhole single-unit column vertical lifting device includes a C-shaped collar and a support handle. Both ends of the inner ring of the C-shaped collar are provided with rubber blocks. The support handle is fixed to one end of the outer ring of the C-shaped collar. When in use, the C-shaped collar is tilted and placed on the single-unit column with one end of the C-shaped collar higher than the other end. The C-shaped collar cannot move upward relative to the single-unit column and is stuck on the single-unit column.
[0005] In use, two operators each use a vertical lifting device. The C-shaped collars of the two vertical lifting devices are distributed vertically and tilted onto the single column. At the same time, the two vertical lifting devices are distributed horizontally, so that they are obliquely locked onto the single column. The rubber blocks increase the friction between the vertical lifting devices and the single column, making the vertical lifting devices more firmly locked onto the single column. Utilizing the lever principle, it is easy for two operators to lift the single column vertically using this device. It also changes the previous method of multiple people working together to lift the single column and straighten it. It saves time and effort and has a high safety factor.
[0006] Furthermore, the support handle and the C-shaped collar are arranged on the same plane for easy application of force.
[0007] Furthermore, the support handle is a T-shaped handle, which makes it easier to apply force.
[0008] Furthermore, the support handle is welded and fixed to the C-shaped collar, ensuring structural stability.
[0009] Furthermore, the C-shaped collar is made from anchor bolts, which are strong and easy to source.
[0010] Furthermore, the support handle is covered with a rubber sleeve for easy operation by workers.
[0011] The beneficial effects of this utility model are as follows: The vertical lifting device of this utility model cleverly arranges the C-shaped collar at an angle, so that the C-shaped collar is locked onto the single column. At the same time, it cleverly utilizes the lever principle to solve the problem of difficult lifting of a single column. Moreover, the device has a simple structure, low manufacturing cost, is easy to carry, is suitable for downhole environments, and is highly practical. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0017] In this description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0019] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] like Figure 1 As shown, a downhole single-unit column vertical lifting device includes a C-shaped collar 1 and a support handle 2. Both ends of the inner ring surface of the C-shaped collar 1 are provided with rubber blocks 3. The support handle 2 is fixed to one end of the outer ring surface of the C-shaped collar 1. When in use, the C-shaped collar 1 is tilted and fitted onto the single-unit column 4, and one end of the C-shaped collar 1 is arranged higher than the other end. The C-shaped collar 1 cannot move upward relative to the single-unit column 4 and is stuck on the single-unit column 4.
[0021] When in use, two operators each need a vertical lifting device, such as... Figure 2 As shown, the C-shaped collars 1 of the two vertical lifting devices are distributed vertically and inclinedly fitted onto the single column 4. At the same time, the two vertical lifting devices are distributed horizontally. At this time, the two vertical lifting devices are obliquely locked onto the single column 4. The friction between the vertical lifting devices and the single column 4 is increased by the rubber block 3, making the vertical lifting devices more firmly locked onto the single column 4. Utilizing the lever principle, it is easy for two workers to lift the single column 4 vertically using this vertical lifting device. It also changes the previous method of multiple people working together to lift the single column 4 and straighten it. It saves time and effort and has a high safety factor.
[0022] In practice, the support handle 2 and the C-shaped collar 1 are arranged on the same plane to facilitate the application of force.
[0023] In practice, the support handle 2 is a T-shaped handle, which makes it easy to apply force.
[0024] In this specific embodiment, the support handle 2 is welded and fixed to the C-shaped collar 1, resulting in a stable structure.
[0025] In this specific embodiment, the C-shaped collar 1 is made of anchor rod, which has high strength and is easy to obtain materials for.
[0026] In this specific embodiment, the support handle 2 is covered with a rubber sleeve to facilitate operation by the operator.
[0027] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
