Description

Technical Field

[0001] The present invention relates to the field of electromechanical installation and construction, and specifically to a pipeline lifting device and a method of use. Background Art

[0002] In the prior art, high-altitude lifting of pipelines usually adopts the lifting method of placing the pipeline horizontally, which is safe and reliable. However, when lifting in a small or narrow space, vertical lifting is often selected.

[0003] However, the existing vertical pipeline lifting technology has the following problems:

[0004] ① When the pipeline is hoisted, the center of gravity of the vertical pipeline will rise. During this process, the pipeline is prone to shaking. Even in windy weather, if the pipeline connection is not firm enough, there is a risk of falling, which seriously threatens the safety of construction site personnel.

[0005] ② To prevent the pipeline from falling during the lifting process, the relevant operators adopted the method of welding and fixing the pipeline and its related components before lifting, and then cutting and removing them after the lifting was completed. This process greatly increased the time cost and resulted in very low construction efficiency.

[0006] ③Cutting and dismantling the pipeline after welding can easily cause pipeline corrosion, shortening the service life of the pipeline.

[0007] Therefore, there is an urgent need to invent a new vertical pipe lifting device that can take into account both safety and efficiency. It must ensure that the pipeline is always in a stable state during the lifting process, without shaking or even falling, effectively eliminating safety hazards during the lifting process and ensuring the safety of the construction site; and it must be simple to operate, convenient and fast, and can ensure construction efficiency.

[0054] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0055] In the technical solutions disclosed in the present application, unless otherwise stated, the directional words used, such as "up, down, left, right", are generally defined based on the drawing direction of the corresponding drawings, and "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description of the reference drawings, the same mark in different drawings represents the same element.

[0056] According to the first aspect of the present application, a pipeline lifting device is provided, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown, it includes: a supporting frame 4, a top frame 2 and a hanging rope 1;

[0057] The support bracket 4 is used to vertically place the pipe 3. At least two support clamps 6 are provided on the support bracket 4 along the circumference of the pipe 3. The support clamps 6 are used to clamp the pipe 3. When two support clamps 6 are provided, the line connecting the two support clamps 6 passes through the axis of the pipe 3.

[0058] The top frame 2 is used to be installed on the top of the pipe 3. The top frame 2 is formed with a rope hole 202 for passing the lifting rope 1. The lower end surface of the top frame 2 is provided with at least two top frame clamps 8 arranged along the circumference of the pipe 3. The top frame clamps 8 are used to clamp the pipe 3. Similarly, when the number of top frame clamps 8 is two, the connecting line of the two top frame clamps 8 passes through the axis of the pipe 3.

[0059] The lifting rope 1 is coaxially arranged with the pipeline 3 , the bottom end of the lifting rope 1 is fixedly connected to the supporting frame 4 , and the upper end of the lifting rope 1 passes through the top frame 2 .

[0060] In the above technical solution, the support bracket 4 is first fixedly connected to the bottom end of the lifting rope 1, and the bottom end of the lifting rope 1 is completely fixed and locked. The lifting rope 1 is usually a steel wire rope, and there are two ways to lock the steel wire rope:

[0061] Method 1. Twist and lock method: stagger and cross-wrap the two ends of the wire rope, and then use pliers or a wrench to twist the two ends of the wire rope to lock it tightly.

[0062] Method 2. Mechanical locking method: Use a mechanical device to install a pliers or clamps at both ends of the wire rope, and tighten the screws or handles to keep it tight.

[0063] The pipe 3 is then placed vertically on the support frame 4, the lifting rope 1 passes through the pipe 3, and then the top frame 2 is installed on the top of the pipe 3 and the upper end of the lifting rope 1 passes through the rope hole 202, that is, the support frame 4 and the top frame 2 clamp the pipe 3 from the top and bottom respectively, and at the same time, the support clamp 6, the top frame clamp 8 and the rope hole 202 cooperate to keep the pipe 3 and the lifting rope 1 in a coaxial position relationship, preventing the two from shaking when hoisting at high altitude. This lifting device is firmly connected to the pipe 3 and is simple and quick to install, solving the problem of the pipe 3 being prone to shaking when hoisting vertically, and avoiding the time-consuming and labor-intensive problem of welding the pipe 3 and the related lifting device in the prior art for vertical pipe hoisting, thereby achieving the purpose of safely and efficiently hoisting the pipe 3 at high altitude. The supporting frame 4 and the top frame 2 may be shaped like a circular plate, a circular frame, a square plate, a square frame, a cross, or other similar shapes, and are not limited to the above-mentioned shapes. The supporting clamp 6 and the top frame clamp 8 may be shaped like a plate, a tube, a block, or other similar types, and are also not limited to the above-mentioned clamps. This application does not impose any specific restrictions on these.

[0064] In this embodiment, if Figure 1 、 Figure 3 、 Figure 7 As shown, each supporting clamp 6 is movably mounted on the upper end face of the supporting frame 4 in the radial direction of the pipe 3; each top frame clamp 8 is movably mounted on the lower end face of the top frame 2 in the radial direction of the pipe 3. In the technical solution disclosed herein, both the supporting clamp 6 and the top frame clamp 8 are installed in a radially movable manner, so that the supporting clamp 6 and the top frame clamp 8 can be moved and adjusted according to the diameter of different pipes 3 until the clamp is adjusted to a suitable position to achieve the clamping degree required for lifting the pipe 3. This design makes the device suitable for lifting pipes 3 of different specifications, realizing the multi-purpose use of a lifting device. Among them, the movable methods include but are not limited to: slide rails, long holes, elastic parts, etc., and the technical solution does not make specific limitations here.

[0065] In some embodiments, as Figure 3 As shown, the support bracket 4 is provided with a first long hole 401 for connecting the support card 6; Figure 7 As shown, the top frame 2 is formed with a second elongated hole 201 for connecting the top frame clamp 8. In the technical solution disclosed herein, the supporting clamp 6 is movably mounted on the supporting frame 4 through the first elongated hole 401 by means of a bolt connection; the top frame clamp 8 is movably mounted on the top frame 2 through the second elongated hole 201 by means of a bolt connection. The bolt connection is not only simple in structure, easy to install, and has a strong effect, but also allows the clamping strength of the clamp to be adjusted arbitrarily and the workpiece can be replaced at any time as needed.

[0066] In some specific embodiments, such as Figure 3 and Figure 4 As shown, the supporting clamp 6 includes an outer supporting clamp 601, and the outer supporting clamp 601 is used to clamp the outer wall of the bottom end of the pipe 3; and / or, as shown Figure 7 、 Figure 8 As shown, the top frame clamp 8 includes an outer top frame clamp 801, which is used to clamp the outer wall of the top end of the pipe 3. The outer support clamp 601 and / or the outer top frame clamp 801 are provided to act on the outer wall of the pipe 3, so that the pipe 3 is always in a stable vertical state during the lifting process, and at the same time, it can prevent the pipe 3 from shaking and falling during the lifting process.

[0067] In other specific embodiments, Figure 4 As shown, the supporting clamp 6 also includes an inner supporting clamp 602. When hoisting, the inner supporting clamp 602 is placed inside the pipe 3, and the inner supporting clamp 602 is arranged correspondingly to the outer supporting clamp 601. The inner supporting clamp 602 is used to clamp the inner wall of the bottom end of the pipe 3, so that the outer supporting clamp 601 and the inner supporting clamp 602 cooperate to form a common clamping on the pipe wall of the pipe 3, so that the clamping effect is better; and / or, as Figure 8 The top frame clamp 8 shown also includes an inner top frame clamp 802. When hoisting, the inner top frame clamp 802 is placed inside the pipe 3, and the inner top frame clamp 802 is arranged correspondingly with the outer top frame clamp 801. The inner top frame clamp 802 is used to clamp the inner wall of the top of the pipe 3, so that the outer top frame clamp 801 and the inner top frame clamp 802 cooperate to form a common clamping on the pipe wall of the pipe 3, which also makes the clamping effect better. Preferably, as Figure 4The outer support fixture 601 shown is an angle steel, which is bolted to the upper end face of the support bracket 4. The angle steel is used to clamp the outer wall of the pipe 3. The support fixture 6 also includes a lower connecting plate 603. One end of the lower connecting plate 603 is formed with a lower connecting plate hole (not shown in the drawings) that matches the first long hole 401. The lower connecting plate 603 is bolted to the angle steel and the support bracket 4 through the lower connecting plate hole. The other end of the lower connecting plate 603 is fixed with an inner support fixture 602. The distance between the angle steel and the inner support fixture 602 is adjusted by sliding the angle steel to ensure that the pipe wall is clamped. Among them, the inner support fixture 602 is made of galvanized steel pipe in this solution. There are three main reasons:

[0068] ① Galvanized steel pipe is made of metal with high hardness, solidity and durability. It can press the pipe wall to the maximum extent and is not easily deformed or damaged by squeezing;

[0069] ②The galvanized material is of high quality and not easy to rust;

[0070] ③ The galvanized steel pipe has a tubular structure and can be well matched to the shape of the pipe wall when placed in the pipe 3, resulting in a better clamping effect.

[0071] Similarly, if Figure 8 The outer top frame clamp 801 is also an angle steel, which is bolted to the lower end surface of the top frame 2 and is used to clamp the outer wall of the pipe 3. The top frame clamp 8 also includes an upper connecting plate 803, one end of which is formed with an upper connecting plate hole (also not shown in the drawings) that matches the second long hole 201. The upper connecting plate 803 is bolted to the angle steel and the top frame 2 through the upper connecting plate hole. The other end of the upper connecting plate 803 is fixed with the inner top frame clamp 802. In this solution, the inner top frame clamp 802 is also made of galvanized steel pipe. The reasons for selecting galvanized steel pipe are the same as above and will not be repeated here.

[0072] In some other embodiments, such as Figure 1 、 Figure 2 As shown, a lifting ring 10 is installed at the upper end of the lifting rope 1, and the lifting ring 10 is used to be fixedly connected to the lifting device, making the device more convenient to use.

[0073] In this embodiment, if Figure 3 As shown, the support frame 4 is a cross-shaped structure, with two symmetrical cross angles of the support frame 4 fixed with lifting rope connectors 5. In the technical solution disclosed herein, the support frame 4 is designed as a cross-shaped structure. While ensuring the stability of the device during lifting, the cross shape saves more material than circular or other shaped frames.

[0074] Preferably, Figure 3As shown, the support frame 4 is composed of a cross consisting of a long channel steel and two short channel steels. The outer ends of the two short channel steels are welded to the two side ends of the long channel steel. The two symmetrical angles on the cross are respectively fixed with hanging rope connectors 5. Figure 5 As shown, the lifting rope connector 5 is made of galvanized steel pipe (galvanized steel pipe is strong, durable and rust-resistant). The galvanized steel pipe is installed on the cross through the corner connector 7. At the same time, the four ends of the cross are respectively installed with support clamps 6. During the lifting operation, the lower end of the lifting rope 1 is sequentially passed through the two galvanized steel pipes, and the support clamps 6 clamp the pipe wall of the pipe 3 from four directions.

[0075] In some embodiments, as Figure 3 As shown, a rope protection sleeve 9 is installed in the rope connector 5 to prevent the rope 1 from repeatedly rubbing against the rope connector 5 during use, thereby protecting the rope 1.

[0076] In this embodiment, if Figure 1 and Figure 7 As shown, the top frame 2 is designed as a cross-shaped structure (the advantages of the cross-shaped structure are not repeated here); wherein the cross can be welded or connected by bolts through corner connecting pieces 7, and the lower end surfaces of the four ends of the cross are respectively installed with top frame clamps 8; Figure 2 As shown, a rope protection sleeve 9 is also installed in the rope hole 202. The purpose is: in actual construction, in order to facilitate installation, the diameter of the rope hole 202 is usually slightly larger than the diameter of the lifting rope 1. However, sometimes the diameter of the rope hole 202 is designed to be too large, so that after the installation of the device is completed, the rope 1 shakes in the rope hole 202 due to the large size difference between the rope hole 202 and the lifting rope 1. It is easy for the lifting rope 1 to repeatedly rub against the hole wall in the rope hole 202, thereby causing wear on the lifting rope 1. In the long run, it will not only shorten the service life of the lifting rope 1, but also pose a certain risk. Therefore, a rope protection sleeve 9 is installed in the rope hole 202 to prevent the lifting rope 1 from repeatedly rubbing against the rope hole 202 during use, thereby shortening the service life of the lifting rope 1 and protecting the lifting rope 1. At the same time, it also reduces the shaking of the lifting rope 1, and further improves the limiting effect of the rope hole 202. In some other specific embodiments, such as Figure 3 As shown, a rope protection sleeve 9 is also installed in the rope connector 5, which is also used to prevent the rope 1 from repeatedly rubbing against the rope connector 5 during use, thereby shortening the service life of the rope 1 and protecting the rope 1.

[0077] The rope guard 9 can be made of a wide variety of materials, usually elastic materials, such as rubber, industrial sponge, etc., as long as it can be inserted into the rope hole 202 to fill the excess space of the rope hole 202. Preferably, a rubber guard ring can be used.

[0078] In some embodiments, as Figure 6 、 Figure 7 As shown, the top frame 2 is composed of two L-shaped pieces 203 bolted together by corner connecting pieces 7. In this technical solution, the top frame 2 is a detachable structure, and the corner connecting pieces 7 are symmetrically fixed at the cross angles, making it more convenient to install the suspension rope 1 through the rope hole 202.

[0079] The second aspect of the present application further provides a method for using a pipeline lifting device, comprising the following steps:

[0080] Step 1: Fix the bottom end of the hanging rope 1 to the supporting bracket 4;

[0081] The bottom end of the sling rope 1 is fixedly connected to the sling rope connector 5 on the support bracket 4, and one end (i.e. the bottom end) of the sling rope 1 is firmly fixed and locked by a mechanical device;

[0082] Step 2: Fix the pipe 3 on the support frame 4;

[0083] Install the pipe 3 on the support frame 4, adjust the support clamps 6 so that the outer support clamps 601 and the inner support clamps 602 respectively clamp the pipe wall of the pipe 3, and pass the top end of the suspension rope 1 through the inside of the pipe 3, out from the top end of the pipe 3, and through the rope hole 202 of the top frame 2;

[0084] Step 3: Fix the top frame 2 to the upper end of the pipe 3;

[0085] Install the top frame 2 on the upper end of the pipe 3, adjust the top frame clamp 8 so that the outer top frame clamp 801 and the inner top frame clamp 802 respectively clamp the pipe wall of the pipe 3, and fill the rope hole 202 with the rope sleeve 9;

[0086] Step 4: Install the lifting ring 10 and hang it on the lifting device;

[0087] Install a lifting ring 10 on the upper end of the lifting rope 1, and hang the lifting ring 10 on the hook of the lifting device;

[0088] Step 5: Start lifting;

[0089] Turn on the lifting button to start lifting.
