Description

Technical Field

[0001] The utility model relates to the field of steel pipe production, in particular to a steel pipe hoisting structure. Background Art

[0002] The patent document with the Chinese patent authorization announcement number CN212924133U discloses a technical solution entitled "A special hook for steel pipes", which includes the following technical features: a horizontal plate, a strip plate, and a round rod. During actual lifting, the round rod is inserted into the port of the steel pipe, and then the steel pipe is lifted upward. Among them, in the process of lifting the steel pipe, the round rod supports the upper port of the steel pipe, and the circumferential surface of the round rod and the steel pipe port are both arc-shaped, so the contact area between the round rod and the steel pipe port will be very small during lifting. Since most steel pipes are very heavy, there is a large force between the steel pipe port and the round rod, which will cause the force per unit area of ​​the steel pipe port to be very large, which is prone to wear, deformation, cracking and other adverse conditions; especially when lifting bundles of steel pipes, the above-mentioned adverse conditions are particularly obvious. Therefore, it is very necessary to design a steel pipe lifting structure that can solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of the present invention is to solve the above-mentioned problems and shortcomings and to provide a steel pipe lifting structure, which not only facilitates lifting operations but also avoids excessive force per unit area during lifting, thereby greatly reducing the probability of adverse conditions such as wear, deformation and cracking during the steel pipe lifting process. The structure is particularly suitable for lifting bundles of steel pipes and has very high reliability and applicability.

[0004] The technical solution of the present utility model is achieved as follows:

[0005] A steel pipe lifting structure is characterized in that it includes an annular belt and at least one confining belt, wherein the two ends of the confining belt are connected to the annular belt, and the inner wall of the confining belt and the inner wall of the annular belt jointly enclose a sleeve groove for sleeved steel pipe ends.

[0006] Preferably, the loop belt is an annular polyester synthetic fiber flat belt.

[0007] Preferably, the crotch belt is a flat belt made of polyester synthetic fiber.

[0008] Preferably, the two ends of the apron band are located below the horizontal center line of the annular band, and the two ends of the apron band are respectively located on both sides of the vertical center line of the annular band.

[0009] Preferably, a lifting steel ring is provided on the top of the ring belt.

[0010] The beneficial effects of the present invention are as follows: on the steel pipe hoisting structure, an annular belt can be used to encircle the end of the steel pipe, which not only increases the contact area, but also helps to ensure that the hoisting is very safe and stable; a confining belt can be used to encircle the end of the steel pipe, which can prevent the steel pipe hoisting structure from sliding toward the middle of the steel pipe when the steel pipe is hoisted, thereby helping to make the steel pipe hoisting structure have high safety and stability. The confining belt and the annular belt are jointly enclosed to form a sleeve groove for sleeved end of the steel pipe, which can help to achieve safe and stable hoisting. Therefore, the steel pipe hoisting structure can not only facilitate the hoisting operation, but also avoid excessive force per unit area during hoisting, thereby greatly reducing the probability of adverse conditions such as wear, deformation and cracking during the steel pipe hoisting process. It is particularly suitable for hoisting bundles of steel pipes and can have very high reliability and applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figures 1 to 3 As shown, the steel pipe lifting structure described in the present invention includes an annular belt 1 and at least one circumferential belt 2. The two ends of the circumferential belt 2 are connected to the annular belt 1. The inner wall of the circumferential belt 2 and the inner wall of the annular belt 1 together enclose a sleeve groove 10 for sleeved the end of the steel pipe.

[0016] In the steel pipe hoisting structure, the annular belt 1 is used to encircle the end of the steel pipe, which not only increases the contact area, but also helps to ensure that the hoisting is very safe and stable; the confining belt 2 is used to surround the end of the steel pipe, which can prevent the steel pipe hoisting structure from sliding toward the middle of the steel pipe when the steel pipe is hoisted, thereby helping to make the steel pipe hoisting structure have high safety and stability. The confining belt 2 and the annular belt 1 are jointly enclosed to form a sleeve groove 10 for sleeved steel pipe ends, which can help to achieve safe and stable hoisting. Therefore, the steel pipe hoisting structure can not only facilitate the hoisting operation, but also avoid excessive force per unit area during hoisting, thereby greatly reducing the probability of adverse conditions such as wear, deformation and cracking during the steel pipe hoisting process. It is particularly suitable for hoisting bundles of steel pipes and can have very high reliability and applicability.

[0017] The structure of the steel pipe hoisting structure is very simple and reliable, which not only facilitates manufacturing but also helps to reduce the manufacturing cost.

[0018] like Figures 1 to 3 As shown, the loop belt 1 is an annular polyester synthetic fiber flat belt. This not only makes the loop belt 1 have good flexibility, but also ensures that the loop belt 1 has high structural strength and durability, and can effectively increase the contact area between the loop belt 1 and the steel pipe. This also makes storage and management easier, thereby helping to further improve the reliability and applicability of the steel pipe lifting structure.

[0019] like Figures 1 to 3 As shown, the apron strap 2 is a flat polyester synthetic fiber strap. This not only makes the apron strap 2 flexible, but also ensures high structural strength and durability, and effectively increases the contact area between the apron strap 2 and the steel pipe. This also makes storage and management easier, thereby helping to further improve the reliability and applicability of the steel pipe lifting structure.

[0020] The ends of the apron band 2 can be tied with a knot or sewn on the hoop band 1 with high-strength sutures, or the ends of the apron band 2 and the hoop band 1 can be woven into an integral structure, and the ends of the apron band 2 and the hoop band 1 can be locked together by rivets, bolts or other locking components. In this way, a very stable and reliable steel pipe lifting structure can be assembled, which can meet the needs of actual use.

[0021] like Figure 1 and Figure 2 As shown, the two ends of the confinement belt 2 are located below the horizontal centerline of the hoop belt 1, and the two ends of the confinement belt 2 are located on both sides of the vertical centerline of the hoop belt 1. This enables the confinement belt 2 to stably achieve the confinement effect, thereby effectively preventing the steel pipe hoisting structure from sliding toward the middle of the steel pipe, thereby making the hoisting safer and more stable.

[0022] like Figure 1 and Figure 2 As shown, when more than two apron bands 2 are provided, one of the apron bands 2 can be located in the middle of the annular band 1 .

[0023] like Figures 1 to 3 As shown, a hoisting steel ring 3 is provided on the top of the ring belt 1. This not only facilitates the hanging of the hook, but also ensures that the hanging part of the hook has high structural strength, thereby helping to further improve the reliability and applicability of the steel pipe hanging structure.

[0024] like Figures 1 to 3 As shown, the lifting steel ring 3 can be either sleeved on the ring belt 1 or connected to the ring belt 1 through a connecting belt, thus meeting the installation and positioning requirements of the lifting steel ring 3.

[0025] like Figure 4 As shown, when it is necessary to hoist a steel pipe, two steel pipe hoisting structures are used, and the ring belts 1 on the two steel pipe hoisting structures are respectively sleeved on the two ends of the steel pipe 100, and the confinement belts 2 on the two steel pipe hoisting structures are respectively wrapped around the two end ports of the steel pipe 100; two slings 200 with hooks 201 at the ends are selected, and one end of the two slings 200 with hooks 201 is hung on the hoisting steel rings 3 on the two steel pipe hoisting structures through the hooks 201, and the other ends of the two slings 200 are hoisted by the main hoisting rope 300. In this way, there is no need to set a crossbar between the two slings 200, and the two steel pipe hoisting structures can be prevented from sliding toward the middle of the steel pipe, which not only reduces the difficulty of hoisting, but also reduces the cost of steel pipe hoisting. This steel pipe hoisting structure can hoist both single steel pipes and bundles of steel pipes, and it has very strong applicability.
