Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline installation technology, specifically, it relates to a device for pipeline hoisting. Background Technology
[0002] Pipeline hoisting is a systematic operation process that uses lifting equipment to safely and accurately install pipelines and auxiliary components into predetermined positions. Its core lies in solving the spatial positioning problem of heavy, long-span pipelines through mechanization. This process is widely used in high-temperature and high-pressure pipelines in the petrochemical industry, multi-pipe parallel systems in urban underground integrated pipe corridors, and large-scale water and steam transmission networks. Because pipelines come in various forms, such as straight pipes, bends, and reducers, specialized hoisting equipment is required during construction to achieve axial fixation and angle adjustment of the pipelines, ensuring that the flange connection accuracy meets millimeter-level requirements.
[0003] Currently, pipeline hoisting at construction sites is mainly achieved using lifting slings or scissor clamps. Lifting slings require manually winding and securing the pipeline after lifting it, which involves repeated lifting and raising, increasing the risk of falls from heights and making the securing of individual pipes time-consuming, severely impacting construction efficiency. After hoisting, removing the slings requires lifting the pipeline again, which can easily cause a 5-10mm axial misalignment, necessitating repeated recalibration. While scissor clamps simplify the fixing process compared to lifting slings, their rigid structure with an unfolded diameter of 1.2-1.5 meters is difficult to deploy in narrow sections of pipe racks or densely built-up areas. Furthermore, their significant weight makes single-person operation difficult, further limiting their applicability in small spaces or high-rise building pipe shafts, resulting in a significant increase in labor and equipment costs.
[0004] Based on this, the present invention proposes a device for pipeline hoisting to solve the problems existing in the prior art. Utility Model Content
[0005] In view of this, the main purpose of this utility model is to provide a device for pipeline hoisting, so as to solve the problems of long hoisting time and large size of traditional hoisting processes, which make it difficult to deploy in narrow sections of pipe corridors or densely built areas.
[0006] To achieve the above objectives, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] An apparatus for pipe hoisting, comprising:
[0008] The clamping assembly includes two double-arc clamping steel plates. The upper ends of the two clamping steel plates are hinged together by a pivot, and the lower ends are equipped with arc-shaped clamping plates that match the pipe. The two clamping steel plates perform scissor motion along the pivot.
[0009] An axial positioning component is disposed between adjacent clamping components and is fixedly connected to the clamping components;
[0010] The hoisting linkage assembly is located on the upper end of the clamping assembly, hinged to the upper end of the clamping steel plate, and connected to the hoisting cable. Hoisting components are movably mounted on the hoisting cable.
[0011] In a preferred embodiment, the hoisting linkage assembly includes:
[0012] The linkage hinge plate has two ends that are connected to the upper end of the clamping steel plate and the vertically arranged connecting plate to form a double hinge connection, thus forming a spatial parallel four-bar mechanism.
[0013] The slip ring is located at the end of the connecting plate and is slidably connected to the hoisting cable.
[0014] In a preferred embodiment, the axial positioning member is a high-strength threaded rod, and is sleeved with an outer collar disposed on the clamping steel plate.
[0015] In a preferred embodiment, the two ends of the axial positioning member are further threaded with positioning nuts, which are located on both sides of the collar.
[0016] In a preferred embodiment, the inner side of the arc-shaped clamping section of the clamping steel plate is further provided with a groove, which engages with a locking strip provided on the outer side of the flexible pad.
[0017] In a preferred embodiment, the clamping steel plate and the clip are provided with positioning holes that match the position, and the positioning holes are connected to positioning pins.
[0018] In a preferred embodiment, the lower end of the clamping steel plate is further provided with an extension locking plate, which is rotatably disposed inside the clamping steel plate.
[0019] In a preferred embodiment, the rear end of the locking plate is further provided with a locking block, which is rotatably disposed in the clearance groove at the lower end of the clamping steel plate and connected to the clamping steel plate by a pin.
[0020] In a preferred embodiment, the lower inner end of the clamping steel plate is further provided with a relief slope, which matches the outer surface of the locking plate.
[0021] In a preferred embodiment, the hoisting cable is a flexible cable.
[0022] Compared with the prior art, this utility model provides a device for pipe hoisting, which has the following beneficial effects:
[0023] 1. By setting up the clamping components, the double-arc clamping steel plate structure can automatically wrap and clamp the outer surface of the pipe under the action of gravity and reaction force, effectively improving construction efficiency.
[0024] 2. By setting up the hoisting linkage components, the unfolding height and width of the upper part of the clamping steel plate can be effectively reduced, thus effectively reducing the size of the device. It can be adapted to operation in narrow sections of pipe corridors and densely built areas, and is simple and convenient to use.
[0025] 3. By setting up axial positioning components, the relative distance between adjacent clamping components can be controlled, preventing the two clamping components from moving towards each other due to external lifting force during hoisting, which would affect the safety and standardization of pipeline hoisting.
[0026] 4. By using lifting winches and lifting components, the lifting components can automatically align themselves during lifting by sliding on the lifting winches, ensuring that the lifting point is always located at the geometric center of the pipeline and avoiding eccentric lifting. This solves the problems of long lifting time, large size, and difficulty in deployment in narrow sections of pipe corridors or densely built-up areas that are inherent to traditional lifting processes.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] The following is combined Figures 1 to 6 The structure of the device for pipe hoisting according to this utility model is described.
[0042] A device for pipe hoisting includes a hoisting linkage assembly, an axial positioning component 7, and several clamping assemblies. Specifically, the clamping assembly adopts a double-arc clamping steel plate 2 with an opposing opening and closing structure. The upper ends of the two blades are hinged together by a rotating shaft 10, and the lower ends are equipped with arc-shaped clamping plates to clamp the pipe 1. When the hoisting linkage assembly drives the upper ends of the clamping steel plates 2 to move towards each other, the clamping steel plates 2 perform a scissor motion along the rotating shaft 10, and the opposing displacement of the lower arc plates achieves a wrapping clamping of the outer wall of the pipe 1. The axial positioning component 7 is arranged between adjacent clamping assemblies to control the axial distance between adjacent clamping assemblies. The hoisting linkage assembly is located at the upper end of the clamping assembly and is hinged to the upper end of the clamping steel plate 2. The upper end is connected to the flexible hoisting winch 5. A hoisting component 6 is also movably installed on the hoisting winch 5. During use, the hoisting component 6 slides on the hoisting winch 5 to achieve automatic centering of the hoisting component 6 during hoisting, so that the hoisting point is always located at the geometric center of the pipeline, effectively avoiding eccentric hoisting of the pipeline 1.
[0043] In a preferred embodiment, such as Figure 1 and Figure 2As shown, the hoisting linkage assembly includes a linkage hinge plate 3, a connecting plate 8, and a slip ring 4. The two ends of the linkage hinge plate 3 are respectively connected to the upper end of the clamping steel plate 2 and the vertically arranged connecting plate 8, forming a spatial parallel four-bar linkage. The axial displacement of the connecting plate 8 drives the simultaneous opening and closing of the clamping steel plates on both sides. The slip ring 4 is fitted onto the end of the connecting plate 8 and forms a sliding connection with the hoisting winch 5. During hoisting, the hoisting point position is automatically adjusted by the winch tension. This design ensures that the lateral dimension of the linkage mechanism in its retracted state is less than or equal to the outer diameter of the pipe, and the unfolded height and width are effectively reduced compared to traditional scissor-type hoists. It is particularly suitable for operations in narrow sections of pipe corridors and densely built-up areas, enabling rapid deployment by a single person at multiple points while ensuring that the space occupancy rate of hoisting operations is reduced to the industry average.
[0044] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the axial positioning component 7 is a high-strength threaded rod, which is used in conjunction with the outer collar 21 set on the clamping steel plate 2. Positioning nuts are threaded to both ends of the axial positioning component 7. The positioning nuts are located on both sides of the collar 21 and are used to control the relative position of the axial positioning component 7 and the collar 21. This controls the relative distance between adjacent clamping components during use, and prevents the two clamping components from moving towards each other due to the external lifting force during hoisting, which would affect the safety and standardization of the hoisting of the pipeline 1.
[0045] In a preferred embodiment, such as Figure 1 , Figure 2 Figure 3 and Figure 4 As shown, the inner side of the arc-shaped clamping section of the clamping steel plate 2 is also provided with a groove 22, which engages with a locking strip 13 located on the outer side of the flexible gasket 11. During use, the locking strip 13 is inserted into the groove 22 to install the flexible gasket 11 on the inner side of the arc-shaped clamping section of the clamping steel plate 2, thus facilitating protection of the outer surface of the pipe 1 and the inner surface of the clamping steel plate 2 during pipe hoisting. The locking strip 13 is preferably made of flexible rubber.
[0046] Specifically, the clamping steel plate 2 and the clamping strip 13 are provided with positioning holes that match the positioning pins 12. This allows the clamping strip 13 to be locked on the clamping steel plate 2 by the positioning pins 12 during use, preventing the flexible gasket 11 from moving due to the disturbance of the pipe 1 during hoisting. It also makes it easy to replace the damaged flexible gasket 11.
[0047] In a preferred embodiment, such as Figure 1 , Figure 2 Figure 3 and Figure 5As shown, the lower end of the clamping steel plate 2 is also provided with an extended locking plate 9, which is rotatably installed on the inner side of the clamping steel plate 2. When the pipe 1 enters the clamping range of the clamping steel plate 2, the upper end of the locking plate 9 is squeezed by the outer wall of the pipe to generate a lever effect, driving the lower end arc-shaped claw to fit against the surface of the pipe. The inner friction plate of the locking plate 9 forms a ring engagement with the surface of the pipe, realizing a secondary force-enhancing locking in addition to the basic clamping force, further ensuring the clamping and lifting effect of the pipe 1, and at the same time, it can also match the lifting and installation of pipes 1 with different outer diameters.
[0048] Specifically, such as Figure 1 , Figure 2 Figure 3 and Figure 5 As shown, the rear end of the locking plate 9 is also provided with a locking block 91. The locking block 91 is rotatably installed in the clearance groove 23 at the lower end of the clamping steel plate 2, and is connected to the clamping steel plate 2 through the pin 14, so as to realize the rotatable installation of the locking plate 9 at the lower end of the clamping steel plate 2.
[0049] Specifically, such as Figure 1 , Figure 2 Figure 3 and Figure 5 As shown, the lower inner end of the clamping steel plate 2 is also provided with a clearance slope that cooperates with the outer surface of the locking plate 9.
[0050] The operating principle of the pipeline hoisting device described in this utility model is as follows:
[0051] Before hoisting, assemble the corresponding number of clamping components and hoisting cables 5 of suitable length according to the pipe specifications. Form a modular hoisting unit through the axial positioning component 7, and connect the hoisting component 6 to the crane hook. When hoisting, the hook presses down, causing the clamping steel plate 2 to automatically open under the reaction force of the pipe 1 surface. After being lowered to the predetermined clamping position, the axial positioning component 7 is manually fine-tuned to ensure that the pipe is centered. Then, the hook is lifted to trigger the linkage hinge plate 3 to drive the clamping steel plate 2 to close. At the same time, the locking plate 9 extends and clamps the pipe wall through the lever self-locking mechanism, realizing automatic force increase and locking at the moment of hoisting.
[0052] When in use, this device effectively shortens the single hoisting cycle compared to traditional processes. Furthermore, the lateral dimension of the device when it is stowed is less than or equal to the outer diameter of the pipe, making it particularly suitable for operations in narrow sections of pipe corridors and densely built-up areas. It can also significantly improve construction efficiency and positioning accuracy under complex working conditions.
[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
