Description

Technical Field

[0001] This utility model relates to the field of oil extraction equipment technology, and more specifically, to an auxiliary installation device for oil extraction pipelines. Background Technology

[0002] In oil extraction operations, it is often necessary to install, replace, or connect oil pipelines such as tubing and casing at the wellhead. Traditional methods mainly rely on cranes in conjunction with manual operation to lift, straighten, and align the tubing strings to the center of the wellhead.

[0003] However, traditional pipeline transportation is inefficient and requires manual alignment, which is time-consuming and labor-intensive, especially in oil pipeline operations where tubing is frequently pulled up and down. Moreover, manual operation makes it difficult to ensure that the tubing axis is precisely aligned with the wellhead centerline, which can easily cause thread damage or poor sealing. Furthermore, manual adjustment can cause the oil pipeline to shake during transportation, which can easily collide with the inner wall of the channel and cause damage.

[0004] In existing pipeline transportation processes, guide structures are also used to assist in guiding oil pipelines to replace manual adjustment. However, these guide structures are generally only suitable for a single type of pipeline and usually adopt surface contact guidance. In oil extraction, an operating environment that requires high safety, the greater the damage to the pipeline, the greater the hidden hazards and the lower the safety. Therefore, it is necessary to reduce the damage to the pipeline during pipeline transportation. Utility Model Content

[0005] The purpose of this application is to provide an auxiliary installation device for oil pipelines, which solves the technical problem of adjusting and aligning with the oil extraction channel during oil pipeline transportation and reducing damage to the pipeline during transportation.

[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0007] An auxiliary installation device for oil pipeline development includes a support frame.

[0008] Preferably, a ring plate is provided on the upper surface of the support frame, and an arc-shaped push plate is radially slidably provided on the surface of the ring plate, the arc-shaped push plate being connected to a radial drive assembly.

[0009] Preferably, two arc-shaped push plates are radially symmetrically arranged on the ring plate.

[0010] Preferably, the inner arc side of the arc-shaped push plate is provided with a plurality of round wheels, which are evenly arranged along the arc of the arc, and the rotation direction of the round wheels is vertical.

[0011] Preferably, the ring plate is provided with two layers of symmetrical arc-shaped push plates in a vertical direction.

[0012] Preferably, the ring plate is connected to a rotary drive assembly, and the rotation direction is along the radial direction of the ring plate.

[0013] Preferably, the arc-shaped push plate is provided with a speed sensing component.

[0014] Preferably, the radial drive assembly includes a slide rod, and a sliding hole is radially opened on the surface of the ring plate. The slide rod is slidably disposed in the sliding hole, and an arc-shaped push plate is fixed to one end of the slide rod facing the center of the ring plate.

[0015] Preferably, a sliding rod is fixedly connected to each end of the outer arc of the arc-shaped push plate.

[0016] Preferably, the two sliding rods are fixedly connected together by a connecting plate at one end that passes through the outside of the ring plate. A screw is radially inserted into the connecting plate and connected by a threaded connection.

[0017] Preferably, one end of the screw passes through the surface of the ring plate, and the screw is engaged with the surface of the ring plate by the locking blocks on both sides of the ring plate.

[0018] Preferably, the inner arc openings of the two symmetrical arc-shaped push plates are arranged facing each other, and when the two symmetrical arc-shaped push plates clamp the pipe, several wheels on the inner arc of the arc-shaped push plates roll into contact with the surface of the pipe.

[0019] Preferably, the rotary drive assembly includes an annular protrusion.

[0020] Preferably, the annular protrusion is fixed on the upper surface of the support frame, the annular protrusion matches the bottom of the ring plate, and the ring plate is rotated relative to the support frame through the annular protrusion.

[0021] Preferably, the rotary drive assembly includes a gear ring, and a gear ring is fixedly disposed on the outer ring of the ring plate. The gear ring meshes with a gear, and the gear is rotatably disposed on the upper surface of the support frame.

[0022] Preferably, the gear has a vertical through-hole, and a screw is fitted into the thread of the through-hole.

[0023] Preferably, after the ring plate is rotated into place, the bottom of the screw abuts against the upper surface of the support frame below the gear.

[0024] Preferably, the speed sensing component includes a sensing block and a sensor.

[0025] Preferably, a sensing block is provided at the eccentric end of the wheel, the sensor is fixedly mounted on the arc-shaped push plate, the sensing head of the sensor is close to the outer circle of the wheel, the sensor is connected to the controller through a circuit, the controller is connected to the signal light through a circuit, and the signal light is fixed on the arc-shaped push plate.

[0026] The technical solution of this application has at least the following advantages and beneficial effects:

[0027] In order to achieve accurate alignment of oil pipelines, this invention is equipped with radially rotatable arc-shaped push plates. By using the "four-point" rolling clamping of the vertical double-layered arc-shaped push plates symmetrically arranged in each layer, the pipeline is statically constrained in any radial section. This ensures coaxial alignment and allows for controllable tilting through different axial amounts between the upper and lower layers. This solves the limitations of traditional conveying methods, which are difficult to align with oil channels and can only be conveyed vertically.

[0028] In this invention, in order to achieve rapid and stepless adjustment of the alignment position of pipes with different diameters, each arc-shaped push plate is independently controlled by a radial drive assembly consisting of a screw, a slide bar, and a connecting plate.

[0029] In this invention, in order to reduce damage to the pipe surface during pipe guidance, vertically rotating wheels are evenly distributed on the inner side of the arc-shaped push plate, changing the line-to-surface contact to multi-point rolling contact, reducing friction, significantly reducing scratches and coating peeling on the pipe surface, and improving safety in oil extraction operations.

[0030] In this invention, to reduce the excessively high pipeline transport speed, which could cause excessive friction between the pipeline and the channel and lead to pipeline damage, the real-time downward speed of the pipeline is converted into a rotational speed signal by using an eccentric sensing block and sensor on the wheel. The controller illuminates an indicator light the instant the speed exceeds the threshold to remind the operator to slow down and avoid high-speed impacts on the channel wall or underground tools.

[0040] Example 1

[0041] Please refer to Figures 1-6 This utility model provides an auxiliary installation device for oil and gas pipelines, including a support frame 1. The support frame 1 is placed above the surface channel of oil extraction. The support frame 1 is movable by casters 11. The middle part of the frame is hollow, so that the hoisting equipment above it will pass through the support frame 1 when hoisting oil and gas pipelines into the channel.

[0042] Positioning nails 9 are vertically slidably fitted on the four corners of the support frame 1. When the support frame 1 moves to the passage, the positioning nails 9 can be vertically inserted into the ground to limit the displacement of the support frame 1 and maintain its stability.

[0043] Furthermore, in order to solve the problems of inaccurate channel positioning caused by swaying during traditional oil pipeline hoisting and transportation, as well as frictional damage to the pipeline surface during positioning and guidance, a pipeline guiding structure is installed above the middle of the support frame 1.

[0044] The pipeline guiding structure includes a ring plate 2, an arc-shaped push plate 3, rollers, and a radial drive assembly 5.

[0045] The radial drive assembly 5 includes a slide bar 51, a connecting plate 52, a screw 53, and a handle 54.

[0046] Specifically, a ring plate 2 is provided on the upper surface of the support frame 1. A sliding hole is radially opened on the surface of the ring plate 2. A sliding rod 51 is slidably installed in the sliding hole (the sliding direction is radial). An arc-shaped push plate 3 is fixed to one end of the sliding rod 51 facing the center of the ring plate 2. A sliding rod 51 is fixedly connected to each end of the outer arc of the arc-shaped push plate 3, thereby ensuring that the arc-shaped push plate 3 slides radially (without rotating).

[0047] The two sliding rods 51 are fixedly connected together by a connecting plate 52 at one end, which passes through the outside of the ring plate 2. A screw 53 is radially passed through the connecting plate 52 and is connected by a threaded connection. One end of the screw 53 passes through the surface of the ring plate 2 and is locked onto the surface of the ring plate 2 by the locking blocks on both sides of the surface of the ring plate 2, thereby restricting the radial sliding of the screw 53 and allowing it to rotate only. The other end of the screw 53 is fixed with a handle 54.

[0048] Preferably, when the handle 54 is turned, the screw 53 is rotated, and the radial displacement of the arc-shaped push plate 3 on the slide rod 51 is driven by the thread. When the hoisting equipment hoists and transports the pipeline into the oil extraction channel, the radial position of the arc-shaped push plate 3 can be adjusted to abut against the pipeline, thereby adjusting the radial position of the pipeline and maintaining alignment accuracy with the oil extraction channel below.

[0049] Preferably, in order to improve the stable conveying (no shaking) of the pipeline during the guiding process of the arc-shaped push plate 3, two arc-shaped push plates 3 are radially symmetrically arranged on the ring plate 2 (the symmetrical point is the center of the ring plate 2). Both arc-shaped push plates 3 are radially displaced by matching screws 53 to clamp the pipeline, thereby maintaining the stability of the pipeline during conveying without shaking. In addition, when adjusting the radial position accuracy of the pipeline, one arc-shaped push plate 3 moves towards the inside of the ring plate 2, while the symmetrical arc-shaped push plate 3 moves towards the outside of the ring plate 2, so that the two arc-shaped push plates 3 can always clamp the pipeline and maintain stability.

[0050] In addition, several round wheels 4 are rotatably arranged on the inner arc side of the arc-shaped push plate 3, and are evenly arranged along the arc shape. The rotation direction of the round wheels 4 is vertical. When the arc-shaped push plate 3 moves close to the pipeline, the round wheels 4 on the arc-shaped push plate 3 will contact and abut the surface of the pipeline. When the pipeline is vertically transported by the hoisting equipment, the round wheels 4 will roll and contact the surface of the pipeline, replacing the surface friction of the existing guide structure with rolling friction, thereby reducing the damage to the pipeline surface when guiding the pipeline, and thus improving the safety of subsequent transportation of oil extraction pipelines.

[0051] Preferably, the inner arc openings of the two symmetrical arc-shaped push plates 3 are arranged facing each other. When the two symmetrical arc-shaped push plates 3 clamp the pipe, the several round wheels 4 on the inner arc of the arc-shaped push plate 3 can achieve matching clamping (several rolling contact points form arc clamping) when transporting pipes of different diameter specifications to the oil extraction channel. Thus, while guiding pipes of different diameters, they can simultaneously maintain rolling contact with the pipe, reducing damage to the pipe surface during transportation.

[0052] Preferably, because the roller 4 makes rolling contact with the pipe, the point contact cannot restrict the vertical state of the pipe. Therefore, two symmetrical arc-shaped push plates 3 are vertically arranged on the ring plate 2 (each arc-shaped push plate 3 is provided with a radial drive component 5). The two arc-shaped push plates 3 and the roller 4 on them are used to restrict the vertical guidance of the pipe (the point contact of the two rollers 4 restricts the vertical conveying state of the pipe).

[0053] Furthermore, although the radial position of the pipe is adjusted by the symmetrically arranged arc-shaped push plate 3 with radial displacement of the shell, it can only match the adjustment of a single radial direction and cannot adjust the entire radial plane, which is limiting. Therefore, the ring plate 2 is also connected to the rotary drive assembly 6, which drives the arc-shaped push plate 3 on the ring plate 2 to rotate in the radial plane, thereby realizing radial alignment adjustment in the entire plane.

[0054] The rotary drive assembly 6 includes an annular protrusion 61, a toothed ring 62, a gear 63, a rotary handle 54, a screw hole 65, and a mounting hole 66.

[0055] Specifically, the annular protrusion 61 is fixed on the upper surface of the support frame 1. The annular protrusion 61 matches the annular groove at the bottom of the ring plate 2, allowing the ring plate 2 to rotate relative to the support frame 1. A toothed ring 62 is fixedly installed on the outer ring of the ring plate 2. The toothed ring 62 meshes with a gear 63. The gear 63 is rotatably mounted on the upper surface of the support frame 1. A rotating handle 54 is coaxially fixed on the gear 63. When the knob handle 64 is manually turned, the ring plate 2 can be rotated through the meshing structure of the gear 63, thereby causing the arc-shaped push plate 3 on the ring plate 2 to rotate, thereby adjusting the alignment position of the pipeline and the oil extraction channel.

[0056] Each time the knob handle 64 is turned, causing the ring plate 2 to rotate into position, the ring plate 2 needs to be temporarily fixed to limit its continued rotation, thereby ensuring the adjustment accuracy of the arc-shaped push plate 3 on it and reducing interference. Therefore, a screw hole 65 is vertically through the gear 63. When the ring plate 2 rotates into position, the operator installs the screw thread into the screw hole 65, so that the bottom of the screw abuts against the upper surface of the support frame 1 below the gear 63. The frictional resistance applied by the bottom of the thread is used to limit the rotation of the gear 63, thereby allowing the ring plate 2 to rotate.

[0057] Furthermore, to address the issue of uncontrollable transport speed during traditional oil pipeline hoisting and transportation (especially in cases of manual pipeline hoisting), which can easily lead to excessively fast pipeline entry into the oil extraction channel and excessive friction between the pipeline and the rough channel surface, causing pipeline damage, particularly in oil extraction channels that are not perfectly straight, this embodiment also includes a speed sensing component 7 and a signal light 8 on the arc-shaped push plate 3. This allows for real-time sensing of the pipeline's transport speed, and the signal light 8 alerts workers when the speed is too high.

[0058] Please refer to the following: Figure 4 The speed sensing component 7 includes a sensing block 71 and a sensor 72.

[0059] Specifically, a sensing block 71 is provided at the eccentric end of the wheel 4, and a sensor 72 is fixedly mounted on the arc-shaped push plate 3. The sensing head of the sensor 72 is close to the outer circle of the wheel 4. The sensor 72 is connected to the controller through a circuit, and the controller is connected to the signal lamp 8 through a circuit. The signal lamp 8 is fixed on the arc-shaped push plate 3.

[0060] When the arc-shaped push plate 3 assists in guiding the pipeline transport, the circular wheel 4 on the arc-shaped push plate 3 will rotate, causing the eccentric sensing block 71 on it to move in a circular motion, repeatedly approaching and then moving away from the sensor 72. This allows the sensor 72 to determine the pipeline transport speed by measuring the rotation speed of the sensing block 71 (refer to the speed sensor 72). When the pipeline transport speed is too fast, the rotation speed of the sensing block 71 on the circular wheel 4 will also increase. When the rotation speed signal sensed by the sensor 72 reaches the sensing threshold set by the controller, the electrical signal it emits will cause the controller to send a signal to the indicator light 8, turning on the indicator light 8 and issuing an alarm signal, thereby reminding the staff that the pipeline transport speed is too fast, so that the staff can adjust the pipeline transport speed.

[0061] Example 2

[0062] In actual oil drilling operations, even with personnel and equipment positioning, some channels may still have a slight tilt. While these small tilts do not affect pipeline transport and oil extraction during normal pipeline operation, due to geological differences and uncertainties, some hard rocks may be exposed on the channel surface. When these hard rocks are located at the tilt angle, they can easily approach and contact the outer surface of the pipeline during transport, causing damage. Therefore, sometimes it is necessary to adjust the angle of the transport pipeline to transport oil into the tilted channel, thereby reducing the probability of approaching the exposed hard rocks on the channel wall.

[0063] Therefore, in this embodiment, each of the upper and lower arc-shaped push plates 3 on the ring plate 2 is individually matched with a radial drive component 5 to ensure that each arc-shaped push plate 3 can be individually adjusted radially. Since the arc-shaped push plate 3 and the pipe surface are in rolling contact (point contact) through the wheel 4, when the symmetrical clamping centers of the upper and lower arc-shaped push plates 3 are not on the same axis (normally, the clamping centers of the two layers need to be kept on the same axis to keep the vertical state of the pipe), the tilt adjustment of the pipe can be realized. When the pipe is tilted, the pipe surface is actually in contact with the four rolling points formed by the wheel 4 on the arc-shaped push plate 3, so it will not interfere with the conveying operation of the pipe.

[0064] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description.
