A non-slip and durable steel pipe isolation ring

Abstract

A non-slip and durable steel pipe isolation ring includes a ring body, which is a circular ring with an opening. The ring body has two staggered ends at the opening and a skirt. When the isolation ring is installed onto a steel pipe, the skirt is in close contact with the outer surface of the steel pipe. The steel pipe isolation ring of this invention, by providing a skirt, ensures a tight fit between the skirt and the steel pipe surface after installation, greatly increasing the friction between them and effectively preventing slippage of the isolation ring on the steel pipe surface. Furthermore, the width of the skirt on the steel pipe isolation ring can be set to be greater than the diameter of the rope used for hoisting. This allows the rope to be tied to the skirt during hoisting, thus preventing the rope from scratching the surface of the steel pipe.

Description

Technical Field

[0001] This invention relates to the field of pipeline protection components, and in particular to a non-slip and durable steel pipe isolation ring. Background Technology

[0002] With the development of the steel industry, stainless steel has long been one of the most common production materials in human society. It has indispensable applications in fields such as chemical engineering, petroleum, light industry and textiles, food processing, power, machinery manufacturing, and instrumentation. Currently, one of the most common ways to use stainless steel is to manufacture stainless steel pipes. These pipes are generally manufactured in steel mills and then transported to the construction site by trains, trucks, ships, and other means of transportation.

[0003] During the transportation or storage of stainless steel pipes, because the pipes are long, straight, cylindrical, adjacent pipes can fit very tightly together. This makes it inconvenient to install slings or hooks when lifting the pipes. Furthermore, when lifting the pipes, the slings or hooks are usually in direct contact with the pipes, which can easily cause scratches on the pipe surface. In addition, if the pipes are bumped during transportation, two adjacent pipes are also prone to collision or friction, which can damage or deform the pipe walls. In the prior art, isolation rings are commonly used to separate steel pipes during transportation or stacking. For example, the steel pipe isolation ring disclosed in CN104555063A has a circular ring structure with two staggered open ends. An annular cavity is formed between the isolation ring body and the open ends. When in use, the open ends are pulled to both ends to form an opening. After the steel pipe is fitted, the open ends are released, and the two open ends return to their original closed state. In this invention, the two open ends are frequently pulled outwards during installation and use, which makes them prone to loosening, thus affecting the anti-slip performance of the isolation ring. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a non-slip and durable steel pipe isolation ring with good anti-slip performance.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a non-slip and durable steel pipe isolation ring, including a ring body, the ring body being a circular ring with an opening, having two intersecting ends at the opening of the ring body, and a skirt provided on the ring body. When the isolation ring is installed on the steel pipe, the skirt can make close contact with the outer surface of the steel pipe, thereby increasing the friction between the isolation ring and the steel pipe and preventing the isolation ring from slipping on the steel pipe.

[0006] Furthermore, the skirt is provided on the left and right sides of the ring body, and the connection point between the skirt and the ring body is located near the inner ring of the ring body. Preferably, the inner side of the skirt is smoothly connected to the inner ring surface of the ring body.

[0007] Furthermore, the skirt has an arc-shaped cross-section, and the curvature is directed towards the interior of the ring body.

[0008] Furthermore, the cross-section of the skirt is straight and slopes inward toward the inside of the ring body.

[0009] Furthermore, the inner surface of the skirt is designed to fit against the steel pipe, and the inner surface is provided with serrations that extend circumferentially along the skirt.

[0010] Furthermore, the width of the skirt is adapted to the thickness of the ring body; preferably, the skirt and the ring body have the same thickness. Since one function of the isolation ring is to separate the two steel pipes, facilitating the passage of the lifting rope or chain through the gap between the pipes for binding, and finally for hoisting, it is evident that the thickness of the ring body must be greater than the diameter of the rope; otherwise, the aforementioned effect cannot be achieved. Therefore, this invention sets the width of the skirt and the thickness of the ring body to be the same, ensuring that the width of the skirt is not less than the diameter of the lifting rope. Consequently, during hoisting, the lifting rope can be completely placed on the skirt, thus preventing wear on the surface of the steel pipes caused by the lifting rope or chain.

[0011] Furthermore, a limiting element is provided on the outer surface of the skirt hem, which can be used to fix and limit the suspension rope or chain. The limiting element can be a protrusion, and the protrusion is located on the outer surface of the skirt hem at the end away from the ring body.

[0012] Furthermore, the skirt wraps around one side of the ring body exactly once, avoiding the inner parts of the intersecting ends.

[0013] Furthermore, the cross-section of the ring body is rectangular or trapezoidal, or it can be other quadrilaterals. Preferably, stripes are provided on the inner surface of the ring body, and the stripes extend in the axial direction of the ring body.

[0014] Furthermore, grooves are provided at both ends of the ring body, which facilitates pulling the two ends during use.

[0015] Furthermore, it also includes a locking mechanism for connecting the two ends of the ring body together.

[0016] Furthermore, the locking mechanism is located near the two open ends of the ring body.

[0017] Furthermore, the locking mechanism can adopt any of the following: Velcro, magnetic structure, or snap-on structure. The locking mechanism only needs to be able to connect and fix the two ends, and its specific structure is not limited.

[0018] The beneficial effects of this invention compared to the prior art are as follows:

[0019] 1. The steel pipe isolation ring in this invention is provided with a skirt. After the isolation ring is installed, the skirt can fit tightly against the surface of the steel pipe, thereby increasing the friction and preventing the isolation ring from sliding in the axial direction of the steel pipe.

[0020] 2. In this invention, the width of the skirt on the steel pipe isolation ring is greater than the diameter of the rope used during hoisting. During hoisting, the rope can be tied on the skirt to avoid scratching the surface of the steel pipe. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way.

[0028] Example 1

[0029] like Figure 1-2 As shown, this embodiment is a non-slip and durable steel pipe isolation ring, including a ring body 1. The ring body 1 is a circular ring with an opening. At the opening of the ring body 1 are two staggered ends. A skirt 2 is provided on the ring body 1. When the isolation ring is installed on the steel pipe, the skirt 2 can make close contact with the outer surface of the steel pipe, thereby increasing the friction between the isolation ring and the steel pipe and preventing the isolation ring from slipping on the steel pipe. The skirt 2 is provided on the left and right sides of the ring body 1, and the connection point between the skirt 2 and the ring body 1 is located near the inner ring of the ring body 1. The inner surface of the skirt 2 is smoothly connected to the inner ring surface of the ring body 1.

[0030] In this embodiment, the skirt 2 has an arc-shaped cross-section, and the curvature is directed towards the interior of the ring body 1. The skirt 2 spirals around the steel pipe once around the ring body 1, and the left and right skirts 2 remain symmetrical on the ring body 1 except for the two intersecting end portions. In this embodiment, the ring body 1 has a rectangular cross-section, and grooves 3 are provided at both ends of the ring body 1. The grooves 3 are used to facilitate pulling apart the two ends of the isolation ring during use, thereby fitting the isolation ring onto the steel pipe.

[0031] Example 2

[0032] like Figure 3-4 As shown, the anti-slip and durable steel pipe isolation ring in this embodiment includes a ring body 1, which is a circular ring with an opening. The opening of the ring body 1 has two intersecting ends. A skirt 2 is provided on the ring body 1. When the isolation ring is installed on the steel pipe, the skirt 2 can make close contact with the outer surface of the steel pipe, thereby increasing the friction between the isolation ring and the steel pipe and preventing the isolation ring from slipping on the steel pipe. The skirt 2 is provided on the left and right sides of the ring body 1, and the connection point between the skirt 2 and the ring body 1 is located near the inner ring of the ring body 1. The inner surface of the skirt 2 is smoothly connected to the inner ring surface of the ring body 1.

[0033] In this embodiment, the cross-section of the skirt 2 is straight and inclined inward towards the inside of the ring body 1, with an inclination angle between 5 and 30 degrees. This allows the top part of the skirt 2 away from the ring body 1 to be in close contact with the surface of the steel pipe after the isolation ring is installed. At the same time, serrations 4 are provided on the inner surface of the skirt 2, and the serrations 4 extend circumferentially along the skirt 2.

[0034] Example 3

[0035] like Figure 5 As shown, the difference between this embodiment and Embodiment 2 is that in this embodiment, the width of the skirt 2 is the same as the thickness of the ring body 1, that is, the difference between the outer diameter and the inner diameter of the ring body 1 is the same as the width of the skirt 2, and a limiting member 5 is provided on the outer surface of the skirt 2. By setting the width of the skirt 2 and the thickness of the ring body 1 to be the same, the present invention ensures that the width of the skirt 2 is not less than the diameter of the lifting rope (generally a steel wire rope), so that during hoisting, the lifting rope can be completely tied to the skirt 2, thus avoiding wear on the surface of the steel pipe caused by the lifting rope or chain.

[0036] Example 4

[0037] The difference between this embodiment and Embodiment 1 is that the isolation ring in this embodiment further includes a locking mechanism. The locking mechanism is located near the two open ends of the ring body 1 and is used to connect the two ends of the ring body 1 together. The locking mechanism can be any one of Velcro, magnetic structure, or snap-on structure. By providing the locking mechanism, the isolation ring in this embodiment can solve the problem of the two ends becoming loose due to frequent pulling during installation and use. The technical solution in this embodiment has been clearly described in text and can be clearly understood by those skilled in the art; therefore, no further drawings are provided.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
