Description

Technical Field

[0001] The present invention relates to the technical field of pipeline installation, and particularly relates to a pipeline hoisting device. Background Art

[0002] Fire pipelines refer to pipeline materials used for fire protection, connecting fire-fighting equipment and appliances, and conveying fire-fighting water, gas or other media.

[0003] When installing and laying fire pipelines, the common methods are overhead installation and underground burial. Considering the installation space and maintenance convenience, some fire pipelines are installed and laid in buildings by overhead hoisting. When hoisting fire pipelines overhead, a hoisting device is needed to hoist the pipelines. Existing hoisting devices mostly use a hanging tooling plate and a clamp to clamp and hoist the fire pipelines.

[0004] However, the entire hoisting device mainly relies on the clamping force of the clamp to fix the pipeline. Once the clamp loosens or is damaged, the pipeline will lose its fixation and there is a risk of falling, seriously threatening the safety of on-site personnel and equipment. Moreover, when hoisting the pipeline using the clamp, the adjustment range of its clamping interval is small, and it has poor applicability to fire pipelines with different diameters. During use, the clamp needs to be matched and replaced according to different pipe diameters. Summary of the Invention

[0005] The purpose of the present invention is to provide a pipeline hoisting device with strong stability, high safety and wide application range.

[0006] With the above concept, the technical solution adopted by the present invention is as follows:

[0007] A pipeline hoisting device, comprising:

[0008] Two parallel and spaced-apart mounting seats, each mounting seat is provided with a mounting channel, and the central axes of the mounting channels of the two mounting seats coincide to form a continuous threading space for accommodating the pipeline;

[0009] A plurality of locking components, at least two of the locking components are circumferentially and evenly arranged on one side of each mounting seat around the mounting channel. Each locking component includes a sliding block and a locking block. The sliding block is movably arranged on the mounting seat and can move towards the mounting channel, and the locking block is fixedly connected to one end of the sliding block facing the mounting channel;

[0010] A connecting component for connecting the two mounting seats.

[0011] Further, the pipeline hoisting device further includes two protective rings, the two protective rings are correspondingly sleeved at both ends of the pipeline, the two mounting seats are located between the two protective rings, and the outer diameters of the two protective rings are greater than the inner diameter of the mounting channel.

[0012] Further, the locking assembly further includes a connecting block, a telescopic member and a limiting plate. The connecting block is arranged on the mounting seat and is provided with a guiding groove along the length direction. The sliding block is slidably arranged in the guiding groove. The limiting plate is arranged on the mounting seat and is provided with a plurality of limiting holes along the length direction. The telescopic member includes a fixed part and a telescopic part which are movably connected. The fixed part is fixedly connected to the sliding block, and the telescopic part can lock the sliding position of the sliding block by inserting into different limiting holes.

[0013] Further, the locking assembly further includes a guiding rod. The two ends of the guiding rod are fixedly connected to the opposite inner walls of the guiding groove along the length direction. The sliding block is sleeved on the guiding rod and can slide axially along the guiding rod.

[0014] Further, the locking assembly further includes a mounting plate. The connecting block and the limiting plate are fixedly arranged on the mounting plate, and the mounting plate is mounted on the mounting seat by bolts.

[0015] Further, the locking assembly further includes a connecting block and a screw rod. The connecting block is arranged on the mounting seat and is provided with a guiding groove along the length direction. The screw rod extends into the guiding groove from one end of the connecting block away from the mounting channel and is rotatably connected to the connecting block. The sliding block is located in the guiding groove and is screwed on the screw rod.

[0016] Further, the mounting seat includes two parallel and spaced-apart mounting discs and at least two connecting members. The mounting discs are provided with mounting holes. The mounting holes of the two mounting discs are coaxially aligned to form the mounting channel. The connecting members are evenly distributed around the mounting channel and are used to connect the two mounting discs.

[0017] Further, the connecting assembly includes two groups of symmetrically arranged connecting brackets and a suspension rod. The two groups of connecting brackets are correspondingly arranged on the two mounting seats. The connecting bracket includes two strip-shaped plates. One ends of the two strip-shaped plates are mutually abutted, and the other ends are respectively clamped between the two mounting discs and are fixedly connected to the two mounting discs through the two connecting members. Coaxially corresponding first connecting holes are provided at the abutting ends of the two strip-shaped plates. The suspension rod sequentially passes through the first connecting holes of the two groups of connecting brackets.

[0018] Further, at least two of the locking assemblies are arranged on the two opposite outer side surfaces of the mounting seat.

[0019] Furthermore, at least two of the connecting components are provided, and the connecting components are arranged circumferentially around the mounting base.

[0020] Advantages of the present invention:

[0021] A pipeline hoisting device provided by the present invention realizes the preliminary positioning of a pipeline by placing the pipeline to be hoisted in the passing space formed by the installation channels of two mounting bases, laying a foundation for subsequent fixing and hoisting operations. Then, according to the pipe diameter of the pipeline, the sliding block is driven to move towards the pipeline. When the sliding block moves to a suitable position, the locking block abuts against the surface of the pipeline. Since the locking components are evenly arranged circumferentially around the installation channel, the locking blocks will apply clamping forces to the pipeline from different directions. These clamping forces act together to tightly fix the pipeline in the installation channel, preventing the pipeline from moving or shaking. Finally, an external hoisting device applies an upward pulling force to the entire hoisting device through the connecting component to hoist the pipeline. During the hoisting process, even in some special cases, such as the loosening or damage of the locking components, the installation channels of the mounting bases can still hold the pipeline to prevent the pipeline from falling, thereby ensuring the safety and reliability of the hoisting operation.

It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0039] As Figures 1 - 4As shown in the figure, the present invention provides a pipeline hoisting device, which includes two mounting seats 1, a plurality of locking components 2 and a connecting component 3. The two mounting seats 1 are arranged in parallel and at intervals. Each mounting seat 1 is provided with a mounting channel, and the central axes of the mounting channels of the two mounting seats 1 coincide to form a continuous threading space for accommodating the pipeline 100. On one side of each mounting seat 1, at least two locking components 2 are evenly arranged circumferentially around the mounting channel. Each locking component 2 includes a sliding block 21 and a locking block 22. The sliding block 21 is movably arranged on the mounting seat 1 and can move towards the mounting channel. The locking block 22 is fixedly connected to one end of the sliding block 21 facing the mounting channel. The connecting component 3 is used to connect the two mounting seats 1.

[0040] By placing the pipeline 100 to be hoisted in the threading space formed by the mounting channels of the two mounting seats 1, the preliminary positioning of the pipeline 100 is realized, laying a foundation for subsequent fixing and hoisting work. Then, according to the diameter of the pipeline 100, the sliding block 21 is driven to move towards the pipeline 100. When the sliding block 21 moves to a suitable position, the locking block 22 abuts against the surface of the pipeline 100. Since the locking components 2 are evenly arranged circumferentially around the mounting channel, the locking blocks 22 will apply clamping forces to the pipeline 100 from different directions. These clamping forces act together to tightly fix the pipeline 100 in the mounting channel, preventing the pipeline 100 from moving or shaking. Finally, an external hoisting device applies an upward pulling force to the entire hoisting device through the connecting component 3 to lift the pipeline 100. During the lifting process, even in some special cases, such as when the locking components 2 become loose or damaged, the mounting channels of the mounting seats 1 can still hold the pipeline 100 to prevent the pipeline 100 from falling, thereby ensuring the safety and reliability of the hoisting operation.

[0041] Specifically, as Figure 1 and Figure 2 shown, the mounting seat 1 includes two mounting disks 11 arranged in parallel and at intervals and at least two connecting pieces 12. The mounting disks 11 are provided with mounting holes 110. The mounting holes 110 of the two mounting disks 11 are coaxially aligned to form a mounting channel. The connecting pieces 12 are evenly distributed around the mounting channel and are used to connect the two mounting disks 11. The integral mounting seat 1 is usually a large integral structure with a large volume and a fixed shape. During transportation, its large size may be restricted by the space of the transportation vehicle and it is difficult to place flexibly, and even may require special large transportation equipment to carry. However, for the mounting seat 1 composed of two mounting disks 11 and connecting pieces 12, it can be disassembled before transportation. The mounting disks 11 are relatively flat and have a small volume. Multiple mounting disks 11 can be conveniently stacked and placed, which not only saves transportation space, but also makes the entire pipeline hoisting device more portable and flexible during handling, installation and operation.

[0042] More specifically, the connecting component 3 includes two sets of symmetrically arranged connecting brackets and a suspension rod 31. The two sets of connecting brackets are correspondingly arranged on the two mounting seats 1. The connecting bracket includes two strip plates 32. One end of the two strip plates 32 abuts against each other, and the other ends are respectively clamped between the two mounting discs 11 and fixedly connected to the two mounting discs 11 through two connecting pieces 12. The abutting ends of the two strip plates 32 are provided with coaxially corresponding first connecting holes, and the suspension rod 31 sequentially passes through the first connecting holes of the two sets of connecting brackets. The symmetric arrangement of the two sets of connecting brackets enables the load to be evenly distributed, and the two strip plates 32 of each set of connecting brackets are arranged with one end overlapping each other and the other end respectively fixed to the mounting disc 11, forming a stable triangular support structure, further improving the stability of the overall structure. Moreover, in the installation process, the two strip plates 32 of each connecting bracket can be first fixed to the corresponding mounting disc 11 respectively, and then the suspension rod 31 is sequentially passed through the first connecting holes of the two sets of connecting brackets to complete the assembly of the entire connecting component. This step-by-step installation method reduces the operational complexity during the installation process and improves the installation efficiency.

[0043] In this embodiment, one end of the connecting piece 12 is provided with an anti-detachment portion, and the other end is provided with a threaded portion. Each connecting piece 12 is configured with a nut. One end of the strip plate 32 away from the first connecting hole is provided with a second connecting hole. At least two third connecting holes are circumferentially and evenly arranged around the mounting hole 110 on the mounting disc 11. The strip plate 32 is clamped between the two mounting discs 11. The second connecting hole communicates with the two third connecting holes. The connecting piece 12 sequentially passes through one of the third connecting holes, the second connecting hole, and the other third connecting hole. The nut is screwed onto the threaded portion and respectively abuts against the two opposite sides of the two mounting discs 11 with the anti-detachment portion to lock and fix the strip plate 32 between the two mounting discs 11.

[0044] In other embodiments, the nut may not be provided, but washers are provided in both the second connecting hole and the third connecting hole to fix the strip plate 32 and prevent the connecting piece 12 from loosening easily.

[0045] Specifically, at least two connecting components 3 are provided, and the connecting components 3 are arranged circumferentially around the mounting seat 1. When the pipeline 100 is relatively heavy, by setting multiple connecting components 3, the force borne by each connecting component 3 is relatively small and is not easily damaged due to exceeding its load-bearing capacity, thereby improving the load-bearing capacity of the entire hoisting device and ensuring the safety and reliability of the hoisting process.

[0046] In this embodiment, referring to Figure 1 , four connecting components 3 and eight connecting pieces 12 are provided. Eight connecting pieces 12 are circumferentially and evenly spaced around the mounting disc 11, and every two adjacent connecting pieces 12 correspond to one connecting component 3.

[0047] Specifically, at least two locking components 2 are provided on the two outer sides of the mounting base 1 facing away from each other. Compared with only providing the locking component 2 on one side, this bilateral setting method makes the binding force on the pipeline 100 stronger, effectively preventing the pipeline 100 from shifting in the installation channel and further improving the stability of the fixation of the pipeline 100.

[0048] In this embodiment, eight locking components 2 are provided on both sides of the two mounting discs 11 of the mounting base 1 facing away from each other. Along the circumferential direction of the mounting disc 11, the locking components 2 and the connecting members 12 are alternately arranged in sequence. Such a layout not only makes the structural design of the mounting base 1 more compact and reasonable, but also can provide an equal fixing force for the pipeline 100 while ensuring a firm connection.

[0049] There are various ways in which the sliding block 21 is movably arranged on the mounting base 1 and can move towards the installation channel.

[0050] In this embodiment, as Figure 1 and Figure 3 shown, the locking component 2 further includes a connecting block 23, a telescopic member 24 and a limiting plate 25. The connecting block 23 is arranged on the mounting base 1 and is provided with a guiding groove 230 along the length direction. The sliding block 21 is slidably arranged in the guiding groove 230. The limiting plate 25 is arranged on the mounting base 1 and is provided with a plurality of limiting holes 250 along the length direction. The telescopic member 24 includes a fixed part and a telescopic part which are movably connected. The fixed part is fixedly connected to the sliding block 21, and the telescopic part can lock the sliding position of the sliding block 21 by inserting into different limiting holes 250. When installing or replacing the pipeline 100, the staff only needs to pull out the telescopic part from the current limiting hole 250, and the sliding block 21 can slide freely in the guiding groove 230. When the locking block 22 abuts against the new pipeline 100, and then insert the telescopic part into the corresponding limiting hole 250 to complete the adjustment. The whole process does not require the aid of complex tools, the operation steps are simple, the adjustment time is shortened, and the work efficiency is improved.

[0051] An arc-shaped concave surface is provided on the side of the locking block 22 facing the pipeline 100. Compared with the contact between a flat surface and the outer wall of the pipeline 100, the arc-shaped concave surface can achieve a larger area of fitting with the outer wall of the pipeline 100, thereby improving the clamping effect.

[0052] More specifically, the locking assembly 2 further includes two adapter plates 28. The two adapter plates 28 are connected to opposite sides of the sliding block 21. On one side of each adapter plate 28 facing the mounting plate 11, two telescopic members 24 are arranged at intervals. There are also two limiting plates 25, which are located on opposite sides of the sliding block 21. On one side of each limiting plate 25 facing the telescopic member 24, a plurality of limiting holes 250 are evenly arranged at intervals along the length direction. The distance between the two telescopic members 24 on the adapter plate 28 is an integer multiple of the distance between two adjacent limiting holes 250 on the limiting plate 25. When the pipeline 100 is subjected to an external force, the telescopic members 24 on both sides can effectively disperse the force to the limiting plate 25, preventing the sliding block 21 from displacing, thereby further improving the stability of the locking block 22 when fixing the pipeline 100.

[0053] More specifically, the locking assembly 2 further includes a guide rod 26. The two ends of the guide rod 26 are fixedly connected to the opposite inner walls of the guide groove 230 along the length direction. The sliding block 21 is sleeved on the guide rod 26 and can slide axially along the guide rod 26. The arrangement of the guide rod 26 enables the sliding block 21 to always move stably in the expected direction, thereby ensuring the stable clamping of the pipeline 100 by the locking block 22 and improving the structural stability of the entire pipeline hoisting device.

[0054] More specifically, the locking assembly 2 further includes a mounting plate 27. The connecting block 23 and the limiting plate 25 are fixedly arranged on the mounting plate 27. The mounting plate 27 is installed on the mounting seat 1 by bolts. During the installation process, the staff can first pre-fix the connecting block 23 and the limiting plate 25 on the mounting plate 27 in a more convenient working area, and then install the entire mounting plate 27 on the mounting seat 1 by bolts, thereby reducing the complexity of operating all components on the mounting seat 1.

[0055] In other embodiments, the locking assembly 2 includes a connecting block 23 and a screw rod. The connecting block 23 is arranged on the mounting seat 1 and is provided with a guide groove 230 along the length direction. The screw rod extends into the guide groove 230 from one end of the connecting block 23 away from the installation channel and is rotatably connected to the connecting block 23. The sliding block 21 is located in the guide groove 230 and is screwed to the screw rod. The screw thread transmission of the screw rod can precisely control the moving distance of the sliding block 21, thereby accurately adjusting the clamping force on the pipeline 100. And when the pipeline 100 is subjected to an external force, the screw thread of the screw rod can effectively prevent the displacement of the sliding block 21, enhancing the structural stability of the entire locking assembly 2.

[0056] Specifically, as Figure 4As shown in the figure, the pipe hoisting device further includes two protective rings 4. The two protective rings 4 are correspondingly sleeved at both ends of the pipe 100. The two mounting seats 1 are located between the two protective rings 4, and the outer diameters of the two protective rings 4 are larger than the inner diameter of the installation channel. During the hoisting process of the pipe 100, the locking assembly 2 may be loosened under the action of various external forces. At this time, the protective ring 4 can play a limiting role to prevent the pipe 100 from undergoing excessive displacement in the axial direction and disengaging from the mounting seat 1. Moreover, during the hoisting, transportation or installation of the pipe 100, both ends of the pipe 100 are the parts most vulnerable to collision and damage. The protective rings 4 are sleeved at both ends of the pipe 100. When an accidental collision occurs, the protective ring 4 will bear the impact force first, avoiding problems such as rupture and deformation of the pipe 100 directly being hit.

[0057] As Figure 5 shown, in this embodiment, the installation steps of the pipe hoisting device are as follows:

[0058] Step 1, install the locking assembly 2, and fix the mounting plate 27 of the locking assembly 2 to the mounting disc 11 through bolts.

[0059] Step 2, assemble the mounting seat 1 and install the strip plate 32. Place the two mounting discs 11 of the mounting seat 1 parallel and at intervals, ensure that the two mounting holes 110 are coaxially aligned, clamp the strip plate 32 between the two mounting discs 11, ensure that the two third connecting holes of the two mounting discs 11 and the second connecting hole of the strip plate 32 are connected and communicated, then insert the connecting piece 12, and fix it with a nut screwed to the connecting piece 12.

[0060] Step 3, install the pipe 100, and pass the pipe 100 through the four mounting holes 110 of the two mounting seats 1 in sequence.

[0061] Step 4, install the protective rings 4, and sleeve the two protective rings 4 at both ends of the pipe 100.

[0062] Step 5, install the suspension rod 31. Select a suspension rod 31 with a suitable length according to the length of the pipe 100, and insert the suspension rod 31 into the second connecting holes of two groups of strip plates 32 in sequence.

[0063] Step 6, adjust the locking assembly 2, move the sliding block 21, insert the telescopic part of the telescopic member 24 into a suitable limiting hole 250, so that the locking block 22 evenly presses against the outer wall of the pipe 100 to fix the pipe 100.

[0064] As Figure 6 shown, in this embodiment, the inspection process of the pipe hoisting device is as follows:

[0065] First, check the locking assembly 2. Check whether the mounting plate 27 is loose. If it is loose, tighten the bolts and record it. If it is not loose, continue to check the connection assembly 3. Check whether the strip plate 32 and the hanging rod 31 are damaged. If they are damaged, replace the relevant damaged parts and record it. If they are not damaged, continue to check the mounting seat 1. Check whether the connecting piece 12 is loose. If it is loose, tighten the nut and record it. If it is not loose, check the protective ring 4. If the protective ring 4 is damaged, replace the protective ring and record it. If it is not damaged, the inspection is completed.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
