Description

Technical Field

[0001] The invention belongs to the technical field of well station pipeline technology and valve equipment integrity and maintenance, and particularly relates to a self-supporting spring support device and an adjustment method. Background Art

[0002] The pipeline process system is one of the main facilities for gas field production. The pipeline support seat is an important accessory for the safe operation of the pipeline system. It is mainly used for load-bearing support at pipeline connection valves, compressor pipeline vibration parts, and long-distance pipelines that produce downward heavy stress. It controls pipeline deformation due to its own weight and pipeline vibration, and prevents mechanical stress from causing pipeline leakage and triggering safety and environmental protection incidents.

[0003] The rigid pipe support seat is composed of a base, a support rod, an adjusting nut and other components. By adjusting the adjusting nut, the support rod of the rigid pipe support seat is adjusted upward to achieve rigid support for the pipeline valve. The rigid pipe support seat cannot effectively deal with support failure caused by pipeline vibration and ground subsidence, and the support force cannot be calculated during the installation process. The installation can only be performed based on experience and feel.

[0004] In order to release pipeline vibration, cope with ground subsidence, and eliminate assembly errors, we consulted relevant standards and specifications for pipeline supports, innovatively designed pipeline support seats, installed and tested them in different pipeline locations, identified deficiencies, and made continuous improvements. We comprehensively analyzed the shortcomings of the installation and use of rigid pipeline support seats, conducted an in-depth analysis of the causes of failure, and proposed a self-supporting spring support device and adjustment method. Summary of the invention

[0005] The purpose of the present invention is to provide a self-supporting spring support device and an adjustment method to solve the existing problem: the rigid pipe support seat is composed of a base, a support rod, an adjustment nut and other components. By adjusting the adjustment nut, the support rod of the rigid pipe support seat is adjusted upward to achieve rigid support for the pipeline valve. The rigid pipe support seat cannot effectively deal with the support failure caused by pipeline vibration and ground subsidence, and the support force cannot be calculated during the installation process. The installation can only be performed based on experience and feel.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a self-supporting spring support device, comprising a support outer cylinder and a support inner cylinder, wherein the support outer cylinder is sleeved on the outside of the support inner cylinder, the support inner cylinder comprises an inner cylinder, a spring, a positioning groove, a bottom plate, a reinforcement hole and a reinforcing plate, the cross section of the bottom plate is circular, the top of the bottom plate is welded with an inner cylinder, the cross section of the inner cylinder is annular, the central axis of the inner cylinder coincides with the central axis of the bottom plate, a positioning groove is provided on the side of the inner cylinder, two positioning grooves are provided and are symmetrically arranged, and a spring is fixedly connected to the inside of the inner cylinder.

[0008] Furthermore, a reinforcing plate is welded to the top of the bottom plate, and four reinforcing plates are provided. The four reinforcing plates are arranged in a ring array along the circumference of the inner tube.

[0009] Furthermore, a reinforcement hole is opened inside the bottom plate, and there are four reinforcement holes, and the four reinforcement holes are staggered with the reinforcing plate.

[0010] Furthermore, the supporting outer cylinder comprises an arc-shaped tray, an adjusting nut, an outer cylinder, a supporting screw, a positioning screw hole and a positioning screw, and the center of the outer cylinder is threadedly connected with the supporting screw.

[0011] Furthermore, the top of the support screw rod passes through the top of the outer cylinder and is connected to the arc-shaped tray through a retaining spring, and an adjusting nut is arranged outside the support screw rod.

[0012] Furthermore, a positioning screw hole is provided on the side of the outer cylinder, and two positioning screw holes are provided. The two positioning screw holes are respectively opposite to the two positioning grooves, and the interiors of the positioning screw holes are both threadedly connected with positioning screws.

[0013] Furthermore, the top of the spring extends to the inner top wall of the outer cylinder and is fixedly connected to the inner top wall of the outer cylinder.

[0014] The present invention is a self-supporting spring adjustment method, which comprises the following steps:

[0015] Step 1: By writing a calculation formula and inputting basic information such as pipe specifications, wall thickness, spring parameters, etc., the pipe weight and the deformation of the supporting spring are automatically generated, and the effectiveness and accuracy of the support are achieved by accurately calculating the elastic force of the spring;

[0016] Step 2: Move the support device to the position where the pipeline needs to be supported, insert the fixing nails into the ground through the reinforcement holes, and reinforce the bottom plate;

[0017] Step 3: Rotate the adjusting nut, so that the supporting screw rod moves upward in cooperation with the thread of the outer tube, so that the arc-shaped tray abuts against the outer wall of the pipeline;

[0018] Step 4: When the pipeline vibrates or the ground sinks, the spring further adjusts the height of the arc tray through elastic action, compensates for the support gap between the arc tray and the outer wall of the pipeline, and the cooperation between the positioning screw and the positioning groove limits the expansion and contraction distance of the spring.

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention automatically generates the pipe weight and the deformation of the supporting spring by setting the spring, writing the calculation formula, inputting the basic information such as pipe specifications, wall thickness, spring parameters, etc., so as to achieve the effectiveness and accuracy of the support and achieve the purpose of load bearing and vibration damping. If the ground sinks, the compression energy of the spring can play the role of gap compensation.

[0021] 2. The present invention sets a positioning groove, a positioning screw hole and a positioning screw for use. The positioning screw is used to fix the pipe in the positioning groove. Once the anti-fatigue performance of the spring fails, the positioning screw can continue to meet the function of supporting the pipeline without any gap. The upper and lower limits of the positioning groove can be designed to control the telescopic distance. The support gravity is visualized to ensure the safe operation of the pipeline.

[0022] 3. The present invention adopts a retaining spring to connect the support screw and the arc tray. The support screw is threadedly connected to the outer tube. The design is ingenious and can be rotated arbitrarily. The support screw is driven to rotate in the outer tube by adjusting the nut, thereby driving the arc tray to move up and fit tightly with the pipeline flange to support the pipeline.

[0023] 4. The cost of the self-supporting spring support device of the present invention is relatively low compared to the adjustable rigid pipeline support seat. According to the number of tools used in the first operation area, the cost saving effect is considerable, and it has a good application prospect in the process pipeline area of ​​oil and gas fields.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the reinforcement holes 205 are provided in a ground environment where holes can be drilled, the bottom plate 204 can be further reinforced by reinforcing nails inside the reinforcement holes 205 to improve the support stability.

[0038] Embodiment 3:

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the supporting outer cylinder 1 includes an arc tray 101, an adjusting nut 102, an outer cylinder 103, a supporting screw 104, a positioning screw hole 105 and a positioning screw 106. The center of the outer cylinder 103 is threadedly connected with the supporting screw 104, and the supporting screw 104 can be rotated arbitrarily to achieve lifting. The top of the supporting screw 104 passes through the top of the outer cylinder 103 and is connected to the arc tray 101 through a retaining ring. The outside of the supporting screw 104 is provided with an adjusting nut 102. The adjusting nut 102 facilitates the rotation of the supporting screw 104 with the help of an external tool.

The interiors of the positioning screw holes 105 are threadedly connected with positioning screws 106. By setting the positioning grooves 203, the positioning screw holes 105 and the positioning screws 106, the positioning screws 106 are used to fix in the positioning grooves 203. Once the fatigue resistance of the spring 202 fails, the positioning screws 106 can continue to meet the function of supporting the pipeline without any gap. The upper and lower limit designs of the positioning grooves 203 can control the telescopic distance. The support gravity is visualized to ensure the safe operation of the pipeline.

[0042] Embodiment 5:

[0043] See also Figure 4 and Figure 5As shown, the top of the spring 202 extends to the inner top wall of the outer tube 103 and is fixedly connected to the inner top wall of the outer tube 103. The automatic adjustable pipe support seat uses the elastic deformation of the spring 202 to convert mechanical work into elastic potential energy to adjust the height of the pipe support seat. The control of the telescopic distance of the spring 202 is limited by the pipe support seat positioning screw 106 in the positioning groove 203, which can compensate for the gap between the pipe and the support part, so as to achieve automatic adjustment of the pipe support seat.

[0044] Embodiment 6:

[0045] A self-supporting spring adjustment method, the adjustment method comprising the following steps:

[0046] Step 1: By writing a calculation formula and inputting basic information such as pipe specifications, wall thickness, spring parameters, etc., the pipe weight and the deformation of the support spring are automatically generated, and the effectiveness and accuracy of the support are achieved by accurately calculating the elastic force of the spring 202;

[0047] Calculation of total pipe weight support

[0048]

[0049] By combining the calculation basis with the calculation parameters, calculate the total weight support force (N) of the pipeline;

[0050] Spring compression height calculation data table

[0051]

[0052] The elastic coefficient of the spring is calculated through various parameters of the spring steel;

[0053] Spring selection and compression height

[0054]

[0055] The spring compression height h (mm) is calculated by selecting the spring model, the total pipe weight support force (N) and the spring elastic coefficient (N). The spring compression height h (mm) is used for judgment to facilitate the effectiveness and accuracy of the support.

[0056] Step 2: Move the support device to the position where the pipeline needs to be supported, insert the fixing nails into the ground through the reinforcement holes 205, and reinforce the bottom plate 204;

[0057] Step 3: Rotate the adjustment nut 102 to adjust the nut 102 so that the support screw 104 moves upward under the action of the thread cooperation with the outer tube 103, so that the arc tray 101 abuts against the outer wall of the pipeline;

[0058] Step 4: When the pipeline vibrates or the ground sinks, the spring 202 further adjusts the height of the arc tray 101 through elastic action, compensates for the support gap between the arc tray 101 and the outer wall of the pipeline, and the positioning screw 106 cooperates with the positioning groove 203 to limit the expansion and contraction distance of the spring 202.

[0059] A specific application of this embodiment is as follows: first, by writing a calculation formula and inputting basic information such as pipeline specifications, wall thickness, and spring parameters, the pipeline weight and the deformation of the support spring are automatically generated. By accurately calculating the elastic force of the spring 202, the purpose of bearing weight and vibration damping is achieved, and the effectiveness and accuracy of the support are realized. Then, the device is moved to the position where the pipeline needs to be supported. According to needs, when the ground conditions permit, the fixing nail is passed through the reinforcement hole 205 to connect with the ground, and then the adjustment nut 102 is rotated. The adjustment nut 102 allows the support screw 104 to move upward under the action of the thread cooperation with the outer cylinder 103, so that the arc tray 101 abuts against the outer wall of the pipeline. When the pipeline vibrates or the ground sinks, the spring 202 further adjusts the height of the pipeline support seat under its own elastic action, compensates for the support gap, releases the pipeline vibration, and responds to the ground sinking. At the same time, the telescopic distance of the spring 202 is limited by the cooperation of the positioning screw 106 and the positioning groove 203. Once the anti-fatigue performance of the spring 202 fails, the positioning screw 106 can also continue to meet the function of pipeline support to avoid the occurrence of gap placement.
