Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting device for multi-bend pipes. Background Technology
[0002] Multi-bend pipelines are generally pipeline structures with multiple bends, and they are widely used in oil and gas production and transportation sites.
[0003] However, the irregular shape of multi-bend pipes makes it difficult to lift them to a horizontal level when horizontal installation is required. Existing cranes using a two-point lifting method typically lift the pipes at two points and then manually pull them into place, which affects the efficiency of multi-bend pipe installation, is time-consuming and labor-intensive, and poses a significant risk. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as low efficiency and time-consuming and labor-intensive hoisting of multi-bend pipes, and to provide a hoisting device for multi-bend pipes.
[0005] This utility model provides a hoisting device for multi-bend pipes, including... The hanger is a truss-type structural component. At least two hanging parts are provided at intervals on the top surface of the hanger, and a first lifting point and a second lifting point are provided at intervals on the bottom surface of the hanger. The first lifting device includes a first connecting part, a first wire rope and a second connecting part connected in sequence. The first connecting part and the second connecting part are respectively used to connect to a multi-bend pipe. The first wire rope passes through the first lifting point part and the second lifting point part. The second lifting device is disposed between the first lifting point and the second lifting point, and the second lifting device connects the hanger and the multi-bend pipe.
[0006] This utility model discloses a hoisting device for multi-bend pipes. By expanding the number of hoisting points through a truss-type structural bracket, the hoisting process of multi-bend pipes becomes more stable and easier to achieve a horizontal state. At the same time, through the combination of a first hoist and a second hoist, the first hoist can be connected to the positions near the two ends of the multi-bend pipe, and the second hoist can be connected to the position near the middle area of the multi-bend pipe. This allows for the stable connection, hoisting, and leveling of the pipes on both sides of the bend, quickly achieving stable hoisting and leveling of multi-bend pipes, and reducing hoisting time and labor costs.
[0007] Preferably, the hanger is a truss structure, comprising an upper crossbeam and a lower crossbeam, with several connecting rods between the upper and lower crossbeams. The first and second lifting points are located at the longitudinal ends of the hanger. The distance between the first and second lifting points is made as wide as possible to accommodate stable connections at the long longitudinal ends of multi-bend pipes.
[0008] Preferably, the hanger has columns at both longitudinal ends, extending at least below the lower crossbeam. The first lifting point and the second lifting point are respectively located at the bottom of the columns. This ensures that the first wire rope is positioned below the hanger, unaffected by the hanger structure, allowing for smooth lifting.
[0009] Preferably, the first lifting point includes a hanging ring or pulley, the second lifting point includes a hanging ring or pulley, the first connecting part includes a flange or clamp, and the second connecting part includes a flange or clamp. The first and second connecting parts enable a stable connection between the first lifting device and both ends of the multi-bend pipe. The first and second lifting points of the hanging ring or pulley allow the first wire rope to move smoothly, facilitating rapid adaptive adjustment of the first wire rope relative to the lifting frame during the lifting of different multi-bend pipes.
[0010] Preferably, the second lifting device includes a connecting member and a second wire rope. The connecting member is connected to the lifting frame. The connecting member is provided with a third lifting point. The second wire rope passes through the third lifting point. Clamps are provided at both ends of the second wire rope.
[0011] Preferably, the second wire rope is equipped with a length adjustment component. The length adjustment component can be used to adjust the length of the second wire rope, thereby adjusting the relative distance between the multi-bend pipe and the hanger, which helps to speed up the leveling of the multi-bend pipe.
[0012] Preferably, the connecting member is provided with a lifting point transition part, through which the first wire rope passes. This ensures that both the first and second wire ropes pass through the connecting member without interfering with each other, thus guaranteeing the stable use of both wire ropes.
[0013] Preferably, the third lifting point includes a hanging ring or a pulley, and the lifting point transition part includes a hanging ring or a pulley.
[0014] Preferably, the hanger is provided with a slide rail, the connecting member is slidably disposed within the slide rail, and the connecting member is connected to a limiting member. This allows the position of the second hanger relative to the hanger to be adjusted according to the position of the bend in the multi-bend pipe.
[0015] Preferably, the limiting member includes a telescopic mechanism disposed on the hanger. This telescopic mechanism adjusts and limits the position of the connecting member relative to the hanger to accommodate lifting multi-bend pipes in different states and structures.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a hoisting device for multi-bend pipes.

Detailed Implementation
[0022] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.
[0023] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.
[0024] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.
[0025] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.
[0026] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.
[0027] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
[0028] Example 1 like Figures 1-3 As shown, a lifting device for a multi-bend pipe includes a hanger 1, a first lifting device 4, and a second lifting device 5. The top surface of the hanger 1 is provided with at least two hanging parts 11 spaced apart, and the bottom surface of the hanger 1 is provided with a first lifting point 2 and a second lifting point 3 spaced apart. The first lifting device 4 includes a first connecting part 41, a first wire rope 42, and a second connecting part 43 connected in sequence. The first connecting part 41 and the second connecting part 43 are respectively used to connect to the multi-bend pipe 8.

[0029] In one or more embodiments, the hanger 1 may include an upper crossbeam 12 and a lower crossbeam 13, with a plurality of connecting rods 14 provided between the upper crossbeam 12 and the lower crossbeam 13 to form a truss-type structural member hanger 1. The first lifting point 2 and the second lifting point 3 are respectively provided at the longitudinal ends of the bottom of the hanger 1. The first wire rope 42 passes through the first lifting point 2 and the second lifting point 3, so that the first connecting part 41 and the second connecting part 43 can be located separately at the longitudinal ends of the hanger 1 with the spacing as wide as possible, so as to be able to connect the two ends of the multi-bend pipe 8 to be lifted, and realize a stable connection of the long longitudinal ends of the multi-bend pipe 8.
[0030] In an optional embodiment, hooking parts 11 are respectively provided at both ends of the top of the upper crossbeam 12. In use, the two hooking parts 11 can be connected by a sling, and then connected to the hook of the crane by the sling to achieve stable lifting of the gantry 1.
[0031] In an optional embodiment, the longitudinal ends of the hanger 1 can be provided with columns 15 respectively. The columns 15 can be rod-shaped structural members that are longer than the connecting rod 14. The columns 15 extend at least to the bottom of the lower crossbeam 13. The first lifting point 2 and the second lifting point 3 are respectively provided at the bottom of the columns 15, so that the first wire rope 42 is always below the hanger 1 and is not affected by the structure of the hanger 1, so that the connection and lifting of the multi-bend pipe 8 can be carried out smoothly.
[0032] In an optional embodiment, the first lifting point 2 can be a hanging ring or a pulley, and the second lifting point 3 can be a hanging ring or a pulley, such as... Figure 1 As shown, both the first lifting point 2 and the second lifting point 3 use pulleys. In use, the first wire rope 42 is threaded through the two pulleys.
[0033] In an optional embodiment, the first connecting part 41 can be a flange or a clamp, and the second connecting part 43 can be a flange or a clamp, such as... Figure 2 As shown, both the first connecting part 41 and the second connecting part 43 use flanges. In use, the two flanges are bolted to the end flanges of the multi-bend pipe 8 respectively, so as to achieve a stable connection between the first lifting device 4 and the two ends of the multi-bend pipe 8. When the first connecting part 41 and the second connecting part 43 use clamps, the clamps are clamped at the ends of the multi-bend pipe 8 near the end flanges, so as to achieve a connection between the first lifting device 4 and the multi-bend pipe 8.
[0034] In an optional embodiment, the first connecting part 41 and the second connecting part 43 of the flange or clamp can be detachably connected to the first wire rope 42 according to the actual situation, so that it can be replaced with different sizes and types according to the actual situation to adapt to the stable connection with different models of multi-bend pipes 8.

The connecting member 51 extends below the lower crossbeam 13 and is provided with a third lifting point 53. The third lifting point 53 may be a hanging ring or pulley provided on the connecting member 51, such as... Figures 1-3 As shown, the third lifting point 53 uses a pulley that is rotatably mounted on the connecting member 51. After the second wire rope 52 passes through the pulley of the third lifting point 53, its two ends are connected to clamps 55. In use, it is connected to the multi-bend pipe 8 through the clamps 55.
[0037] In an optional embodiment, the clamp 55 can be a clamp or other fastener structure that can be engaged and connected, and can be clamped on the multi-bend pipe 8 to connect the multi-bend pipe 8 between the first connecting part 41 and the second connecting part 43, thereby increasing the number of lifting points and achieving stable leveling of the multi-bend pipe 8.
[0038] In one or more embodiments, the second wire rope 52 may be provided with a length adjusting member 6. The length adjusting member 6 can adjust the overall length of the second wire rope 52, thereby adjusting the relative distance between the multi-bend pipe 8 and the hanger 1. This allows the second wire rope 52 to also play a lifting role when the multi-bend pipe 8, connected by the first connecting part 41 and the second connecting part 43, is in the lifting state, and also helps to speed up the leveling of the multi-bend pipe 8.
[0039] In an optional embodiment, the length adjusting member 6 may be a turnbuckle.
[0040] In one or more embodiments, the connecting member 51 may be provided with a lifting point transition part 54, through which the first wire rope 42 passes, so that both the first wire rope 42 and the second wire rope 52 pass through the connecting member 51 without interfering with each other, thus ensuring the stable use of the first wire rope 42 and the second wire rope 52.
[0041] In an optional embodiment, the lifting point adapter 54 can be a hanging ring or a pulley, such as... Figures 2-3 As shown, the lifting point adapter 54 uses a pulley, and the pulley of the lifting point adapter 54 is located above the pulley of the third lifting point 53, so that the first wire rope 42 is located above the second wire rope 52, which can effectively avoid interference between the first wire rope 42 and the second wire rope 52.
[0042] In one or more embodiments, the hanger 1 may be provided with a slide rail 16, and the connecting member 51 may be slidably disposed in the slide rail 16. At the same time, the connecting member 51 is connected to the limiting member 7, so that the position of the second hanger 5 relative to the hanger 1 can be adjusted according to the position of the bend of the multi-bend pipe 8.
[0043] In an optional embodiment, the lower crossbeam 13 of the hanger 1 can be a groove-shaped structural member with a bottom opening to form a slide 16. The top of the connecting member 51 can be provided with a roller or end structure that can slide along the slide 16, so that the connecting member 51 can move smoothly along the lower crossbeam 13 longitudinally to adjust the position of the second hanger 5.
[0044] In optional implementations, such as Figure 3 As shown, the limiting member 7 can be a telescopic mechanism installed on the hanger 1, such as an electric telescopic rod, hydraulic cylinder or other telescopic structure, which can adjust the position of the connecting member 51 relative to the hanger 1 by extending or shortening the telescopic mechanism, so as to adapt to lifting multi-bend pipes 8 in different states and structures.
[0045] This embodiment of a lifting device for a multi-bend pipe involves connecting the first connecting part 41 and one side clamp 55 of the second lifting device 5 to the same side of the bend in the multi-bend pipe 8, and connecting the second connecting part 43 and the other side clamp 55 of the second lifting device 5 to the same side of the bend in the multi-bend pipe 8. This combination of the first lifting device 4 and the second lifting device 5 allows for stable connection and leveling of the multi-bend pipe 8. The entire pipe is lifted by connecting the top hanging part 11 of the hoisting frame 1 with the hoisting rope. The number of lifting points is expanded by the truss-type structural member of the hoisting frame 1, making the lifting process of the multi-bend pipe 8 more stable and easier to achieve a horizontal state. At the same time, by combining the first lifting device 4 and the second lifting device 5, the first lifting device 4 can be connected to the position near both ends of the multi-bend pipe 8, and the second lifting device 5 can be connected to the position near the middle area of the multi-bend pipe 8. This allows for the stable connection, lifting, and leveling of the pipes on both sides of the bend in the multi-bend pipe 8, quickly achieving stable lifting and leveling of the multi-bend pipe 8, and reducing lifting time and labor costs.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
