Description

Technical Field

[0001] The invention relates to the technical field of oil pipeline transportation, in particular to a shock-absorbing oil delivery pipeline clamping device. Background Art

[0002] Most of the oil production and processing requires pipelines for oil transportation. After processing and forming, such pipelines need to be transported to oil production bases or processing workshops for installation and use. Pipeline transportation generally chooses land or water transportation according to geographical location and economic investment. Regardless of the mode of transportation, the pipeline needs to be clamped and stabilized during transportation to avoid damage to the pipeline due to inertia or bumps. Since some specifications of such pipelines have large diameters, large overall volume and weight, the traditional transportation method is mainly to use straps to bundle and stack them in containers. Since the pipe body is a round pipe structure, it is easy to loosen the bundle due to bumps during transportation, and then it is easy to misalign and collide with each other, which not only causes wear and damage to the structure (especially some pipes made of special materials), but also poses a great transportation safety hazard. Some will set a U-shaped bracket at the bottom of the pipeline before loading the pipeline, but this type of bracket is often a welded part with a fixed structure. It can only be used to support the bottom layer and cannot effectively fix the longitudinal stacking of multiple pipelines.

[0003] Therefore, there is an urgent need for a pipe clamping device that can solve the above-mentioned defects. Summary of the invention

[0004] The present invention provides a shock-absorbing oil product transportation pipeline clamping device, which is helpful to solve the problem that some existing large oil product pipelines do not have a suitable tooling clamping structure when they are stacked in multiple layers during transportation. The bundling structure of the pipeline is easily loosened due to bumps during transportation, and then it is easy to be misaligned, collide and squeeze each other, which not only causes wear and damage to the structure, but also poses a major transportation safety hazard.

[0005] The present invention is achieved in that:

[0006] A shock-absorbing oil product delivery pipeline clamping device, comprising at least two spaced-apart clamping assemblies, adjacent clamping assemblies are connected to each other via a plurality of connecting rods; the clamping assembly is a triangular frame structure composed of three bases, and a clamping cavity for clamping the pipeline is provided in the middle; the base comprises a main board, and a first straight plate, a second straight plate and an arc-shaped plate connected end to end in sequence are vertically provided on the outer side of the main board, the inner corner of the first straight plate and the second straight plate is 60°, the inner wall profile of the arc-shaped plate can fit the outer wall of the pipeline to be clamped, the inner walls of the arc-shaped plates on the three bases cooperate to form a clamping structure, and the inner area of ​​the clamping structure is the clamping cavity; A shock-absorbing plate is provided on the inner wall of the arc-shaped plate, and the shock-absorbing plate includes an inner layer and a surface layer. A pulling rope is provided on the composite side of the inner layer and the surface layer. The outer end of the pulling rope extends to the outside of the shock-absorbing plate and is connected to a pull ring. The inner side of the pulling rope can be movably clamped between the inner layer and the surface layer. The pulling rope is located in the internal area of ​​the shock-absorbing plate and is provided with a plurality of extension ropes. The outer side of the extension rope is compositely connected to the surface layer, and the inner side of the extension rope is gap-matched with the inner layer. One side of the pull ring is provided with an adhesive surface for attaching to the outer wall of the pipe. When the pipe is clamped, it rotates about its axial center line toward the threshold direction, which will pull the pulling rope outward, and the extension rope will undergo follow-up deformation to form a wrinkled anti-slip structure on the surface of the surface layer.

[0007] Based on the above technical solution, a flange is provided at the connection between the arc plate and the first straight plate and the second straight plate, and a splicing hole with a through hole structure is provided on the flange. The flanges of adjacent bases are fitted together, and after the splicing holes are aligned, a splicing combination structure is formed through splicing pieces.

[0008] Based on the above technical solution, a rounded corner structure is provided at the outer corner of the base.

[0009] Based on the above technical solution, a shock absorbing groove is provided on the inner wall of the arc plate, the inner end of the shock absorbing sheet is fixed in the shock absorbing groove, and the outer end of the shock absorbing sheet extends to the outside of the shock absorbing groove.

[0010] On the basis of the above technical solution, reinforcing ribs are provided on the front and rear side walls of the main board, the inner end of the reinforcing rib in the length direction is connected to the arc plate, and the outer end is connected to the connection between the first straight plate and the second straight plate. The reinforcing rib is provided with a connecting hole near the outer end in the long side direction, and the connecting hole passes through the reinforcing rib and the main board for installing the connecting rod.

[0011] On the basis of the above technical solution, the pulling rope and the extension rope form a feather-like vein structure.

[0012] On the basis of the above technical solution, the inner layer is provided with a plurality of suction cup grooves in the area below the extension rope, and the openings of the suction cup grooves face outwards.

[0014] On the basis of the above technical solution, a plurality of pull ropes arranged at intervals are provided on the same shock-absorbing plate, and all the pull ropes are connected to the same pull ring.

[0021] 6. Anti-slip pads and suction cup grooves enhance the connection stability between the clamping device and the pipeline and transport vehicle, reducing safety hazards during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0037] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0039] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Example 1: Combination Figures 1 to 8 As shown, this embodiment discloses a shock-absorbing oil pipeline clamping device, which aims to provide a pipeline clamping solution with stable structure, strong clamping force and good shock-absorbing effect to meet the safety fixation requirements of large oil pipelines in multi-layer stacking transportation.

[0041] The shock-absorbing oil product delivery pipeline clamping device specifically comprises two clamping assemblies 100 spaced apart along the axial direction of the pipeline, and the two clamping assemblies 100 are connected to each other through three horizontal connecting rods 300. The two clamping assemblies 100 are respectively sleeved on the axial ends of the pipeline a to clamp and fix the pipeline a.

[0042] Further, such as Figure 2 As shown, the clamping assembly 100 is a triangular frame structure composed of three bases 10, and a clamping cavity 200 for clamping the pipe a is provided in the middle.

[0043] Combination Figure 3As shown, the base 10 includes a main board 1, and a first straight board 2, a second straight board 3 and a curved board 4 which are connected end to end in sequence are vertically arranged on the outer side of the main board 1, that is, the main board 1 is vertically arranged, and the first straight board 2, the second straight board 3 and the curved board 4 are all horizontal board structures perpendicular to the main board 1. This structure similar to an I-beam is conducive to improving the structural strength of the base 10 to support a large-volume and heavy-weight pipeline structure.

[0044] The inner corner of the first straight plate 2 and the second straight plate 3 is 60°, the inner wall profile of the arc plate 4 can fit the outer wall of the pipe a to be clamped, and the inner walls of the arc plates 4 on the three bases 10 cooperate to form a clamping structure, and the inner area of ​​the clamping structure is the clamping cavity 200. Figure 2 As shown, the spliced ​​clamping cavity 200 is a complete circular cavity structure, and the outer contour of the clamping assembly 100 is an equilateral triangle structure, which is conducive to improving the stability of the pipe a during transportation and will not shake easily, and is also conducive to improving the stacking convenience and stability by regularizing the external structure. Fig.12 shown.

[0045] The arc plate 4 is provided with a flange 41 at the connection with the first straight plate 2 and the second straight plate 3, and a splicing hole 42 of a through-hole structure is provided on the flange 41. The flanges 41 of adjacent bases 10 fit together, and after the splicing holes 42 are aligned, a splicing assembly structure is formed through the splicing piece 20 (a structure such as a bolt or a latch). This design not only facilitates the assembly and disassembly of the base 10, but also improves the flexibility and adaptability of the clamping device.

[0046] The outer corners of the base 10 are provided with rounded corners, which helps to reduce potential damage to personnel or surrounding objects during transportation and installation, and also helps to improve the structural strength of the base 10.

[0047] Reinforcement ribs 6 are provided on the front and rear side walls of the main board 1. The inner end of the reinforcement rib 6 in the length direction is connected to the arc plate 4, and the outer end is connected to the connection between the first straight plate 2 and the second straight plate 3. The reinforcement rib 6 not only enhances the overall structural strength of the base 10, but also provides an additional connection point for installing the connecting rod 300. The reinforcement rib 6 is provided with connection holes 61 near the outer end in the long side direction. These connection holes 61 penetrate the reinforcement rib 6 and the main board 1 to facilitate the insertion and fixation of the connecting rod 300. In addition, when the connecting rod 300 is not installed, the connection holes 61 can be used as hoisting holes due to their location advantages.

[0048] The outer side walls of the first straight plate 2 and the second straight plate 3 are provided with anti-skid pads 7. This helps to increase the friction between the clamping device and the transport vehicle or other supporting structure to prevent sliding during transportation.

[0049] A shock-absorbing sheet 5 is provided on the inner wall of the arc plate 4. Specifically, a shock-absorbing groove is provided on the inner wall of the arc plate 4. The inner end of the shock-absorbing sheet 5 is fixed in the shock-absorbing groove, and the outer end of the shock-absorbing sheet 5 extends to the outside of the shock-absorbing groove. This design enables the shock-absorbing sheet 5 to fit more closely on the arc plate 4, thereby improving the shock-absorbing effect. The function of the shock-absorbing sheet 5 is to provide a corresponding buffering and shock-absorbing effect after the base 10 clamps the pipeline a, which helps to appropriately reduce the bumping vibration during transportation, avoid excessive rigid collision between the base 10 and the pipeline a, and thus protect the pipeline structure.

[0050] Furthermore, the shock absorbing sheet 5 includes an inner layer 5a and a surface layer 5b. In this embodiment, the inner layer 5a is made of rubber material, and the surface layer 5b is made of a wear-resistant PET and PP composite film. Figure 4-6 A pulling rope 51 is provided on the composite side of the inner layer 5a and the surface layer 5b, the outer end of the pulling rope 51 extends to the outside of the shock-absorbing plate 5 and is connected with a pull ring 53, the inner side of the pulling rope 51 can be movably clamped between the inner layer 5a and the surface layer 5b, the pulling rope 51 is located in the internal area of ​​the shock-absorbing plate 5 and is provided with a plurality of extension ropes 52, the outer side of the extension rope 52 is compositely connected with the surface layer 5b (that is, the fitting surface 521 of the extension rope 52 close to the surface layer 5b is fixedly connected to the surface layer 5b), and the inner side of the extension rope 52 is gap-fitted with the inner layer 5a (that is, the free surface 522 of the extension rope 52 close to the inner layer 5a is gap-fitted with the inner layer 5a, and the two are not compositely fixed), so that after the extension rope 52 is deformed, it can drive the surface layer 5b in the connected area to undergo synchronous corresponding deformation, but will not drive the inner layer 5a to undergo synchronous corresponding deformation.

[0051] In this embodiment, the pulling rope 51 and the extension rope 52 form a feather-like vein structure, which enables the pulling rope 51 to evenly distribute stress when subjected to external force, thereby improving shock absorption performance. At the same time, the feather-like vein structure is also conducive to maintaining structural stability and continuity of the extension rope 52 during the dynamic deformation process.

[0052] Furthermore, one side of the pull ring 53 is provided with an adhesive surface 531 for attaching to the outer wall of the pipe a. Before use, the adhesive surface 531 is protected by release paper. When in use, the release paper is torn off first, and then the adhesive surface 531 is used to fix one side of the pull ring 53 to the outer wall of the pipe a. When the pipe a is clamped, it rotates around its axial centerline toward the threshold direction, which will pull the pulling rope 51 outward, and the extension rope 52 will deform with the movement, forming a wrinkled anti-slip structure on the surface layer 5b. Figure 7 As shown in the figure, when the pipe a rotates counterclockwise during transportation, the pipe a will drive the pull ring 53 to rotate because the pull ring 53 is connected and fixed thereto. The displacement of the pull ring 53 acts on the pulling rope 51 to pull outward, as shown in FIG. Figure 4 and 5As shown, after the pulling rope 51 is pulled outward, the pulling rope 51 drives the extension rope 52 to tilt outward, and then as shown in FIG. Figure 6 As shown, the extension rope 52 drives the surface layer 5b to deform during this process, so the surface layer 5b forms wrinkles 5c, which increase the friction between the surface layer 5b and the outer wall of the pipe a to prevent or weaken the continued rotation and axial sliding of the pipe a. It should be noted that the pulling rope 51 and the pull ring 53 on different bases 10 in the same clamping assembly 100 are arranged in the same or opposite directions to improve the comprehensiveness of the anti-slip direction. Compared with the existing rope bundling method, this anti-slip structure has a more accurate and efficient action time. Through reasonable combination, it can greatly improve the clamping stability of the pipe a.

[0053] Example 2: Based on Example 1, Fig. 9 As shown, in this embodiment, two pull ropes 51 are arranged at intervals on the same shock-absorbing plate 5, and all the pull ropes 51 are connected to the same pull ring 53, and each pull rope 51 is connected to a plurality of extension ropes 52. This design simplifies the operation process, so that one pull ring 53 can drive multiple pull ropes 51 at the same time, thereby increasing the formation area of ​​the pleats 5c and improving the anti-slip effect.

[0054] Embodiment 3: Based on Embodiment 1, Fig.10 and Fig.11 In this embodiment, the inner layer 5a is provided with a plurality of suction cup grooves 54 in the area below the extension rope 52, and the openings of the suction cup grooves 54 face outward. During use, the suction cup grooves 54 utilize the elasticity of the inner layer 5a itself, and the extrusion force applied to the inner layer 5a after the pipe a is clamped causes the openings of the suction cup grooves 54 to deform appropriately, thereby achieving an adsorption effect, and increasing friction through changes in the concave-convex structure, and further improving the anti-slip effect and clamping stability with the folds 5c of the surface layer 5b.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
