Support device for large pipeline installation

Abstract

This application discloses a support device for large pipeline installation, relating to the field of pipeline installation technology. It includes a base, with a slide rail arranged along its length on the top of the base. A sliding mounting plate is provided on the slide rail and engages with it. The slide rail includes a groove, the dimension of which along the thickness direction of the sliding mounting plate is greater than the thickness of the sliding mounting plate. The sliding mounting plate has several positioning holes along the length of the slide rail, each equipped with a positioning bolt. The base has fixing holes for fixing the positioning bolts. By providing a sliding mounting plate that engages with the slide rail and positioning holes, the device increases the tolerance for displacement of the large pipeline in the radial direction. When the large pipeline shifts, it mitigates the problem of localized high-intensity compression in the connection area, thereby maintaining the normal support function of the device and protecting the pipeline.

Description

Technical Field

[0001] This application relates to the field of pipeline installation technology, and in particular to a support device for large pipeline installation. Background Technology

[0002] Large pipeline installation support devices are closely related to key applications in industries such as industry, energy, petrochemicals, and municipal engineering. As pipeline systems develop towards larger scale, greater complexity, and higher parameters, the technical requirements for support devices are also constantly being upgraded.

[0003] In existing methods, when installing large pipelines, the support device is fixed to the ground or the installation plane by threaded fixing, and then the large pipeline is fixed in position by the pipeline clamp set on the support device. The common method is to connect the base of the support device and the pipeline sleeve by a welded connecting seat, so that the large pipeline is stably fixed on the support device.

[0004] Regarding the aforementioned technologies, the inventors believe that when a large pipeline is fixed by a support device, the contact point between the support device and the pipeline will be subject to long-term vibration from the pipeline; the threaded support device will vibrate due to vibration, and the connection area between the support device and the large pipeline is prone to local high-intensity compression, which will lead to accelerated damage to the support device and damage to the pipeline. Utility Model Content

[0005] The purpose of this application is to provide a support device for the installation of large pipelines, so as to improve the problem of local high-intensity extrusion that can easily occur in large pipelines due to vibration.

[0006] The technical solution for a support device for large pipeline installation provided in this application is as follows:

[0007] A support device for installing large pipelines includes a base, a slide rail provided on the top of the base along its length, a sliding mounting plate slidably engaging with the slide rail, the slide rail including a groove, the dimension of the groove along the thickness direction of the sliding mounting plate being larger than the thickness of the sliding mounting plate; the sliding mounting plate having a plurality of positioning holes along the length direction of the slide rail, the positioning holes being provided with positioning bolts, the base having fixing holes for fixing the positioning bolts; a mounting seat provided on the top of the sliding mounting plate, and a pipe sleeve for fixing large pipelines provided on the top of the mounting seat.

[0008] By adopting the above technical solution, and by setting a sliding mounting plate that slides with the slide rail and a positioning waist hole, the displacement tolerance of large pipelines in the radial direction of the pipeline on the support device is increased. When the large pipeline is displaced, the problem of local high-intensity extrusion in the connection area is improved, thereby maintaining the normal support work of the support device and protecting the pipeline.

[0009] Optionally, the positioning bolt is fitted with an elastic element, one end of which abuts against the base and the other end of which abuts against the sliding mounting plate.

[0010] By adopting the above technical solution, the displacement tolerance of the pipeline and support device along the vertical direction of the mounting seat is increased by adding elastic elements to the positioning bolts, thereby maintaining the normal support function of the support device and protecting the pipeline.

[0011] Optionally, a metal washer is provided between the positioning bolt and the positioning hole.

[0012] By adopting the above technical solution and setting metal washers, the fit between the positioning bolt and the positioning hole is made tighter, thus stabilizing the support device.

[0013] Optionally, an elastic sleeve is provided on the inner wall of the positioning waist hole.

[0014] By adopting the above technical solution and setting an elastic sleeve, the fit tolerance between the positioning bolt and the inner wall of the positioning hole is increased, thus improving the problem of local high-intensity extrusion caused by vibration.

[0015] Optionally, the inner wall of the positioning waist hole is provided with a retaining groove for the elastic sleeve to be embedded.

[0016] By adopting the above technical solution, the elastic sleeve is embedded into the locking groove by setting the locking groove, so that the elastic sleeve is fixed on the positioning waist hole.

[0017] Optionally, the inner sidewall of the slide rail is provided with an elastic pad that abuts against the sidewall of the sliding mounting plate.

[0018] By adopting the above technical solution, and by setting an elastic pad on the side wall of the sliding mounting plate to abut against it, when the support device vibrates, its offset tolerance space along the width direction of the base can be increased, thereby protecting the support device and the pipeline.

[0019] Optionally, one end of the slide rail is provided with an elastic baffle that can abut against the end of the sliding mounting plate along the length of the slide rail.

[0020] By adopting the above technical solution, the elastic baffle assists in positioning the sliding mounting plate within the slide rail, facilitating the threaded connection between the positioning bolts and the fixing holes. When the sliding mounting plate undergoes displacement along the length of the slide rail, the offset tolerance space is increased.

[0021] Optionally, the pipe sleeve includes a pair of interlocking annular plates, with a plurality of connecting screws provided at the interlocking points of the annular plates, and the connecting screws being provided with fixing nuts.

[0022] By adopting the above technical solution and setting up interlocking annular plates, when large pipelines need to be installed on support devices, the interlocking installation method can be used instead of insertion, making it easier to install large pipelines on support devices.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a sliding mounting plate that slides with the slide rail and positioning holes, the displacement tolerance of large pipelines in the radial direction of the pipeline on the support device is increased. When the large pipeline is displaced, the problem of local high-intensity extrusion in the connection area is improved, thereby maintaining the normal support function of the support device and protecting the pipeline.

[0025] 2. By adding elastic elements to the positioning bolts, the displacement tolerance of the pipeline and support device along the vertical direction of the mounting base is increased, thus maintaining the normal support function of the support device and protecting the pipeline;

[0026] 3. By setting up interlocking ring plates, when large pipelines need to be installed on support devices, the interlocking installation method is used instead of insertion, making it easier to install large pipelines on support devices. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0032] A support device for large pipeline installation, as shown in the reference. Figure 1The system includes a horizontal base 1, which is fixed to the predetermined installation position of the pipe by screws and threads; a slide rail 11 is fixedly installed on the top of the base 1 along its length by welding, and in this embodiment, the number of slide rails 11 is preferably two; the slide rail 11 is provided with a sliding mounting plate 2 that slides and engages with it, and the sliding mounting plate 2 is horizontal.

[0033] Reference Figure 1 The sliding mounting plate 2 has several positioning holes 21 along the length of the slide rail 11. The positioning holes 21 are elongated strips with semi-circular ends. In this embodiment, the number of positioning holes 21 is preferably four. Positioning bolts 22 are inserted into the positioning holes 21. The base 1 has a fixing hole 12 for threaded connection and fixation of the positioning bolts 22. The fixing hole 12 is cylindrical. When the large pipeline vibrates and displaces, the positioning bolts 22 move along the length of the positioning holes 21, which improves the problem of local high-intensity compression caused by displacement.

[0034] Reference Figure 1 The top of the sliding mounting plate 2 is fixedly provided with a mounting base 4 by welding. In this embodiment, the mounting base 4 is preferably a trapezoidal plate with three equally spaced arrays.

[0035] Reference Figure 1 The top of the mounting base 4 is fixedly equipped with a pipe sleeve 3 for fixing a large pipe by welding. The pipe sleeve 3 includes a pair of interlocking annular plates 31. The annular plates 31 are semi-circular and have several support beams at both ends to distribute the contact stress between the support device and the large pipe. In this embodiment, the number of support beams is preferably 6. Several connecting screws 32 are provided at the interlocking ends of the annular plates 31 by thread fixing. In this embodiment, the connecting screws 32 are preferably 4. The ends of the connecting screws 32 are provided with fixing nuts 33 by thread connection.

[0036] Reference Figure 2 The inner wall of the positioning waist hole 21 is provided with a retaining groove 212 for the elastic sleeve 211 to be embedded and fixed. The elastic sleeve 211 is provided at the retaining groove 212 on the inner wall of the positioning waist hole 21. The elastic sleeve 211 is a long strip with semi-circular ends. In this embodiment, the material of the elastic sleeve 211 is preferably rubber. When the support device vibrates, the positioning bolt 22 that is close to the elastic sleeve 211 can move in the radial direction of the pipe in the positioning waist hole 21, which improves the situation of local high-intensity compression.

[0037] Reference Figure 1 and Figure 3The slide rail 11 includes a slide groove 113. The dimension of the slide groove 113 along the thickness direction of the sliding mounting plate 2 is greater than the thickness dimension of the sliding mounting plate 2. The slide groove 113 is elongated. The slide groove 113 abuts against the bottom surface of the sliding mounting plate 2, so that the sliding mounting plate 2 is more stably installed in the slide rail 11.

[0038] Reference Figure 1 and Figure 3 The inner sidewall of the slide rail 11 is provided with an elastic pad 111 that abuts against the sidewall of the sliding mounting plate 2. In this embodiment, the elastic pad 111 is preferably made of rubber and is in the shape of a strip. An elastic baffle 112 is fixedly provided at one end of the slide rail 11. The elastic baffle 112 is preferably made of rubber. The sliding mounting plate 2 slides into the slide rail 11 from the end of the slide rail 11 without the elastic baffle 112. When the sliding mounting plate 2 slides into the slide rail 11 and abuts against the elastic baffle 112, the positioning waist hole 21 is located directly above the fixing hole 12, which facilitates the positioning bolt 22 to pass through the positioning waist hole 21 and be threadedly connected to the fixing hole 12.

[0039] Reference Figure 1 and Figure 3 The positioning bolt 22 is fitted with an elastic element 221. One end of the elastic element 221 abuts against the top of the base 1, and the other end abuts against the bottom of the sliding mounting plate 2. In this embodiment, the elastic element 221 is preferably a plurality of overlapping disc springs, and the number of disc springs is preferably 6.

[0040] Reference Figure 1 and Figure 3 A metal washer 222 is provided between the positioning bolt 22 and the positioning hole 21. By providing the metal washer 222, the support device is made more stable and the fit between the positioning bolt 22 and the positioning hole 21 is made tighter. In this embodiment, the material of the metal washer 222 is preferably carbon spring steel.

[0041] The implementation principle of this application embodiment is as follows:

[0042] After the fixed base 1 is fixed, the sliding mounting plate 2 slides into the slide rail 11 from the side of the slide rail 11 without the elastic baffle 112. When the sliding mounting plate 2 abuts against the elastic baffle 112, the positioning waist hole 21 is located above the fixing hole 12. After the elastic element 221 is placed on the fixing hole 12, the positioning bolt 22 passes through the elastic element 221 and is threadedly connected to the fixing hole 12. After the large pipe is fixed to the support device by the interlocking of the annular plate 31, when the large pipe vibrates, the positioning waist hole 21 and the elastic element 221 provide displacement tolerance for the support device, improving the problem of local high-intensity compression that is prone to occur in the support device.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
