Description

Technical Field

[0001] This utility model belongs to the field of oil drilling equipment technology, and relates to an auxiliary operation device for oil drilling sites. Specifically, it is a mechanized lifting device for oil drill pipe alignment operations. Background Technology

[0002] Oil drill pipe is a core tool in drilling operations, connecting the drill bit, transmitting torque, and transporting drilling fluid. Alignment during routine management is crucial for ensuring on-site safety and improving hoisting and transport efficiency. Currently, oil drill pipe alignment mainly relies on traditional manual methods. A typical procedure involves at least four people working together: two use pry bars to lift the drill pipe, while the other two stand on either side of the pipe rack. Once the drill pipe is lifted, they push both ends towards a predetermined baseline, thus achieving alignment.

[0003] This traditional manual operation mode has the following significant drawbacks: Firstly, it requires a large manpower investment and is labor-intensive. Each operation requires at least four people to work together, and the operators need to exert a great deal of physical strength to pry and push, which is inefficient heavy physical labor; Secondly, the work is inefficient. Because it relies on manpower and simple tools, the entire process of prying, pushing, and aligning is repetitive and time-consuming. Thirdly, there are significant safety risks during the operation. During the prying process, the pry bar may slip, causing personnel to lose their balance and fall; when the heavy oil drill pipe is pried up and pushed, there is a risk of it suddenly rolling or falling, which can easily cause crushing, bumping, and crushing injuries to the hands, feet, and bodies of personnel working nearby.

[0004] Therefore, there is an urgent need in this field for a device that can achieve mechanized lifting to replace manual labor and fundamentally overcome the above-mentioned defects. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a lifting device for aligning oil drill pipes, thereby achieving mechanized lifting of oil drill pipes during oil drill pipe alignment operations, and ultimately reducing labor intensity and safety risks.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lifting device for aligning oil drill pipes, comprising a base and a lifting linkage mechanism and a linear drive mechanism mounted on the base; The lifting linkage mechanism includes a first crossbar, a second crossbar, a linkage group, and a support member; the first crossbar and the second crossbar are spaced apart and arranged opposite to each other on the base, and the second crossbar can move on the base in a direction close to or away from the first crossbar; the linkage group is connected between the first crossbar, the second crossbar, and the support member to convert the reciprocating linear motion of the second crossbar into the lifting motion of the support member; The output end of the linear drive mechanism is connected to the second crossbar drive.

[0007] As a limitation of this utility model, the middle part of the support member is recessed inward to prevent the oil drill pipe from slipping off.

[0008] As a further limitation of this utility model, the outer surface contour of the support member extends symmetrically in a conical shape from the center to both ends, so that the middle part of the support member forms the part with the smallest diameter and the two ends form the part with the largest diameter.

[0009] As another limitation of this utility model, the linkage assembly includes a first linkage assembly connected between the first crossbar and the support member, and a second linkage assembly connected between the second crossbar and the support member.

[0010] As a further limitation of this utility model, the first crossbar is fixedly assembled on the base; The first connecting rod assembly is rotatably connected to the first crossbar and the support member at both ends.

[0011] As a further limitation of this utility model, the first crossbar is rotatably mounted on the base; The first connecting rod assembly is rotatably connected to the first crossbar and the support member at both ends, respectively. Alternatively, one end of the first connecting rod assembly is fixedly connected to the first crossbar, and the other end is rotatably connected to the support member.

[0012] As a further limitation of this utility model, the second crossbar is slidably assembled on the base through a linear guide structure; The two ends of the second connecting rod are rotatably connected to the second crossbar and the support member, respectively.

[0013] As a further limitation of this utility model, the second crossbar is rolled onto the base via a linear guide structure; The two ends of the second connecting rod are respectively rotatably connected to the second crossbar and the support member; Alternatively, one end of the second connecting rod assembly is fixedly connected to the second crossbar, and the other end is rotatably connected to the support member.

[0014] As a further limitation of this utility model, the linear drive mechanism includes a linear electric push rod, a controller, and a battery. The output end of the linear electric push rod is connected to the second crossbar via a transmission connection, and the battery is electrically connected to the linear electric push rod through the controller.

[0015] As a further limitation of this utility model, the linear drive mechanism includes a linear electric push rod, a controller, and a battery. The output end of the linear electric push rod is connected to the second crossbar via a transmission connection, and the battery is electrically connected to the linear electric push rod through the controller.

[0016] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) This utility model completely replaces the traditional manual pry bar operation with mechanical jacking, so that operators no longer need to make direct and laborious contact with the heavy and unstable oil drill pipe. This fundamentally eliminates the safety risks such as squeezing, bumping and crushing caused by pry bar slippage or oil drill pipe rolling during the prying process, and greatly reduces the accident rate; (2) This utility model utilizes a linear drive mechanism in conjunction with a lifting linkage mechanism to replace human labor with mechanical force, enabling a single oil drill pipe to be lifted easily and smoothly in one go. It simplifies the heavy physical labor that originally required at least four people to work together into a simple operation that can be completed by two people, significantly reducing manpower input, greatly reducing the labor intensity of operators, and improving the efficiency of oil drill pipe alignment operations; (3) This utility model adopts a specially designed support component with its middle part recessed inward. This structure can effectively restrict the lateral movement of the drill rod during the lifting and alignment process, and plays a good role in preventing slippage and rolling, further ensuring the stability and safety of the operation process.

[0017] In summary, this utility model has a compact structure and simple operation. Its mechanized operation method is not affected by factors such as differences in the physical strength of operators, and it can adapt to the complex and diverse working environment of oil drilling sites. It provides a safe, efficient and reliable mechanized solution for oil drill pipe alignment operations, and has high practical value and promotion prospects. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0021] This embodiment discloses a lifting device for aligning oil drill pipes, such as... Figure 1 and Figure 2 As shown, this embodiment includes a base 1 and a lifting linkage mechanism and a linear drive mechanism 2 mounted on the base 1. Using this embodiment, only two people are needed to easily complete the alignment of the oil drill pipe 9.

[0022] The base 1 serves as the mounting foundation for the lifting linkage mechanism and the linear drive mechanism 2. In use, it enables stable placement of the base above the drill pipes 9 already aligned on the pipe rack, or on a scissor lift platform. In this embodiment, the base 1 is made of manganese steel.

[0023] The lifting linkage mechanism is the core structure of this embodiment. Its function is to convert the horizontal movement of the linear drive mechanism 2 into vertical lifting, thereby lifting or lowering the oil drill pipe 9. Figure 1 and Figure 2 As shown, the lifting linkage mechanism includes a first crossbar 3, a second crossbar 4, a linkage group, and a support member 5. The first crossbar 3 and the second crossbar 4 are spaced apart and opposite to each other on the base 1, and the second crossbar 4 can move on the base 1 in a direction close to or away from the first crossbar 3. The linkage group connects the first crossbar 3 and the support member 5, and the second crossbar 4 and the support member 5, forming a height-variable triangular support structure.

[0024] Furthermore, the linkage assembly includes a first linkage assembly 6 connecting the first crossbar 3 and the support member 5, and a second linkage assembly 7 connecting the second crossbar 4 and the support member 5. In this embodiment, the first linkage assembly 6 includes two parallel first rocker arms that connect both ends of the first crossbar 3 to both ends of the support member 5; the second linkage assembly 7 includes two parallel second rocker arms that connect both ends of the second crossbar 4 to both ends of the support member 5.

[0025] The support component 5 is rotatably connected to both the first link assembly 6 and the second link assembly 7, so that after supporting the oil drill pipe 9, the operator can easily push the oil drill pipe 9 axially to align it with other oil drill pipes 9. For example... Figure 1 and Figure 2 As shown, the middle part of the support member 5 has a radially recessed structure. This structure can effectively restrict the lateral movement of the drill rod during the lifting and alignment process, and plays a good role in preventing slippage and rolling. In this embodiment, it is specifically manifested as a double conical support roller, that is, the outer surface contour of the support member 5 extends symmetrically in a conical shape from the center to both ends, so that the middle part of the support member 5 forms the part with the smallest diameter and the two ends form the part with the largest diameter.

[0026] The linear drive mechanism 2 includes a linear electric actuator fixed to the base 1 and a battery electrically connected to the linear electric actuator via a controller. In this embodiment, the controller and battery are integrated into a control box. For ease of movement during use, the control box can be placed on a flatbed trolley. Figure 1 and Figure 2 As shown, the output end of the linear electric actuator is perpendicular to the second crossbar 4 and is connected to the second crossbar 4 in a transmission manner. When the output end of the linear electric actuator extends, it drives the second crossbar 4 to approach the first crossbar 3. When the output end of the linear electric actuator retracts, it drives the second crossbar 4 to move away from the first crossbar 3.

[0027] It should be noted that, depending on the actual situation, linear electric actuators can also be replaced by linear motors, linear cylinders, etc.

[0028] Based on the above basic structure, the assembly methods of the first crossbar 3, the second crossbar 4, and the base 1, as well as their connection relationships with the linkage assembly, can have the following feasible combinations: 1. The two ends of the first crossbar 3 are fixedly assembled on the base 1 by supports and cannot rotate on its own; the two first rocker arms in the first linkage group 6 must be rotatably connected to the first crossbar 3. The two ends of the second crossbar 4 are slidably assembled with the base 1 via a linear guide structure 8. Specifically, the linear guide structure 8 includes two relatively parallel slide rails fixed on the base 1, and the two ends of the second crossbar 4 form a sliding pair with the slide rails via sliders. The two second rocker arms in the second linkage group 7 must be rotatably connected to the second crossbar 4.

[0029] 2. The two ends of the first crossbar 3 are rotatably assembled on the base 1 through bearings and bearing seats, and can rotate on its own; the two first rocker arms in the first connecting rod group 6 can be rotatably connected to the first crossbar 3 or fixedly connected. The two ends of the second crossbar 4 are slidably assembled with the base 1 via a linear guide structure 8. Specifically, the linear guide structure 8 includes two relatively parallel slide rails fixed on the base 1. The two ends of the second crossbar 4 form a sliding pair with the slide rails via sliders, and the ends of the second crossbar 4 are fixedly connected to the sliders. The two second rocker arms in the second linkage group 7 must be rotatably connected to the second crossbar 4.

[0030] 3. The first crossbar 3 and the base 1, and the second crossbar 4 and the first connecting rod group 6, can adopt the first method or the second method mentioned above; The two ends of the second crossbar 4 are rolled together with the base 1 via a linear guide structure 8. Specifically, the linear guide structure 8 includes two relatively parallel slide rails fixed to the base 1. The two ends of the second crossbar 4 form a sliding pair with the slide rails via sliders, and ball bearings are embedded inside the sliders to allow the second crossbar 4 to rotate relative to the sliders. The two second rocker arms in the second linkage group 7 can be rotatably connected to the second crossbar 4 or fixedly connected.

[0031] Combination Figure 3 and Figure 4 The on-site operation process in this embodiment is as follows: S1. Preparation and Positioning: After the operators check that all connections of the device are safe and reliable, two operators each hold one device and place it at both ends of the oil drill pipe 9, aligning the support 5 directly below the oil drill pipe 9. Figure 3 Status. It should be noted here that, during use, the device can be placed directly on top of the lower, already aligned oil drill pipes 9, or it can be placed on a scissor lift platform for auxiliary operation; S2. Lifting Operation: Activate the linear electric push rod, extending its output end to drive the second crossbar 4 to slide along the linear guide structure 8 towards the first crossbar 3. Through the linkage of the first linkage group 6 and the second linkage group 7, the support member 5 rises smoothly, lifting the oil drill pipe 9 away from the pad bar 10 of the pipe rack. Figure 4 state; S3. Push and Align: After the oil drill pipe 9 is fully lifted and suspended in the air, the operators on both sides can easily push the oil drill pipe 9 by hand under the action of the rotatable support 5, so that it moves axially and quickly aligns with the baseline. S4. Retraction and Cycling: After alignment, the output end of the linear electric actuator retracts, driving the second crossbar 4 away from the first crossbar 3. Through the linkage of the first linkage group 6 and the second linkage group 7, the support 5 smoothly lowers the oil drill pipe 9 onto the pad bar 10, completing the alignment of a single oil drill pipe 9. The device is then moved to perform the alignment operation for the next pipe.

[0032] It should be noted that the above description is merely 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 above embodiments, those skilled in the art can still modify the technical solutions described in the above 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.
