Description

Technical Field

[0001] This invention relates to the field of pipeline construction technology for petrochemical pipeline corridor modules, specifically a method and auxiliary device for pipe laying of large-size pipelines on pipeline corridor modules. Background Technology

[0002] As the scale of projects in the petrochemical industry increases, the application of modular pipe rack installations is also growing. Whether it's a plant-wide pipe rack or a pipe rack within a specific plant area, the high height, long distances, and limited workspace make pipe installation on these racks extremely difficult. Therefore, modular pipe rack construction is increasingly being adopted for project construction. This involves technically cutting long pipe rack installations into several prefabricated modules for installation. Traditional pipe rack installation methods often employ chain hoisting, pipe threading tools, and rail-mounted trolley methods. However, for large-diameter pipe installations, traditional methods are no longer sufficient to meet requirements regarding safety, quality, schedule, and project preservation. Summary of the Invention

[0003] The purpose of this invention is to provide a method and auxiliary device for pipe installation of large-size pipes on pipe gallery modules, so as to solve the problem mentioned in the background art that traditional pipe installation methods can no longer meet the requirements of safety, quality, progress, and protection of results for the installation of large-size pipes.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for pipe laying construction of large-size pipes on a pipe gallery module, comprising: an installation block, and the auxiliary device further comprising: an installation box disposed above the installation block;

[0005] The mounting box is equipped with a rotating rod, and a connecting rope is wound around the rod. The end of the connecting rope extends to the outside of the mounting box and is connected to the lifting lug.

[0006] The mounting block has a placement groove, and a rotating rod is rotatably mounted in the placement groove. A binding rope is wound around the rotating rod, and the end of the binding rope extends to the outside of the mounting block and connects to the insertion block. The mounting block is provided with a fixing member, and the fixing member has a slot.

[0007] The mounting block has mounting grooves parallel to the pipe on both sides. A stop block and an elastic element connected to the stop block are slidably installed in the mounting groove. The mounting block has moving grooves on both sides. A contact block for fitting against the top of the pipe and an elastic element connected to the contact block are slidably installed in the moving groove. The moving path of the contact block is perpendicular to the pipe. A pull rope is installed between the contact block and the stop block.

[0008] Preferably, a pressure roller is provided below the stop for fitting against the top of the pipe;

[0009] The connection between the stop block and the pressure roller is provided with a slot, the pressure roller is slidably inserted into the slot, and a spring is provided between the slot and the pressure roller.

[0010] Preferably, an elastic pad is provided below the mounting block, and a groove for filling gas is formed in the elastic pad.

[0011] Preferably, the insert is provided with a telescopic sleeve for fitting over the outside of the binding rope, and the telescopic sleeve is a multi-stage telescopic sleeve.

[0012] Preferably, the fixing member is slidably provided with a connecting member, the connecting member is provided with a magnetic block, and the insertion block is a magnetic block.

[0013] Preferably, the movable slot is equipped with a touch switch, the mounting slot is equipped with an electromagnet electrically connected to the touch switch, and the side of the stop block facing the electromagnet is equipped with a magnet, the magnetic poles of the magnet and the electromagnet being close to each other are the same.

[0014] As a preferred embodiment, a method for installing large-size pipes on a pipe rack module, based on an auxiliary device for installing large-size pipes on a pipe rack module, specifically includes the following steps:

[0015] S1: Install full-span scaffolding under the crossbeams on the first floor of the pipe gallery module where large-sized pipes will be installed, and set up two cranes on both sides of the same end of the pipe gallery module.

[0016] S2: Use an auxiliary device to secure the center of the pipe and hang the auxiliary device on one of the cranes. Use the crane to place one end of the pipe flat on the crossbeam of the pipe gallery module and make one end of the pipe extend beyond the crossbeam by a certain distance.

[0017] S3: Use an auxiliary device to tie the outer end of the pipe, then use another crane to connect to the auxiliary device, then remove the auxiliary device at the center of the pipe and tie it to the inner end of the pipe. Then, the two cranes lift the pipe at the same time and move it horizontally onto the two crossbeams of the pipe gallery module.

[0018] S4: Remove the auxiliary device from the pipeline and re-tie it to the pipeline. Then, use two cranes to move the pipeline inward toward the inside of the pipe gallery module.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see Figure 1 and Figure 2 An auxiliary device for pipe laying construction of large-size pipes on a pipe gallery module includes: an installation block 1, an installation box 2 installed above the installation block 1; a coil rod 9 is rotatably installed inside the installation box 2, a torsion spring is sleeved on the coil rod 9, the two ends of the torsion spring are respectively connected to the outer wall of the coil rod 9 and the inner wall of the installation box 2, a connecting rope 4 is wound on the coil rod 9, and the end of the connecting rope 4 away from the coil rod 9 extends to the outside of the installation box 2 and is connected to the lifting lug.

[0038] Please see Figure 1 , Figure 2 and Figure 4 The mounting block 1 has a mounting groove, and a rotating rod 10 is rotatably mounted in the mounting groove (a torsion spring is fitted on the rotating rod 10, and the two ends of the torsion spring are respectively connected to the outer wall of the rotating rod 10 and the inner wall of the mounting groove). A binding rope 11 is wound around the rotating rod 10, and the end of the binding rope 11 extends to the outside of the mounting block 1 and is connected to the insert block 12. The mounting block 1 is provided with a fixing member 5, and a slot 51 is provided on the fixing member 5. When the insert block 12 is inserted into the slot 51, the end of the binding rope 11 away from the rotating rod 10 is connected to the fixing member 5.

[0039] Please see Figure 1 , Figure 5 and Figure 6 Mounting block 1 has mounting grooves 16 on both sides (according to...) Figure 1The mounting groove 16 is located on the front and rear sides of the mounting block 1 (i.e., the mounting groove 16 is parallel to the pipe). A stop block 6 is slidably installed in the mounting groove 16, and an elastic element is installed between the mounting groove 16 and the stop block 6. A movable groove 17 is opened on both sides of the mounting block 1 (the movable groove 17 and the stop block 6 are located on the same side). A contact block 8 is slidably installed in the movable groove 17, and an elastic element is installed between the movable groove 17 and the contact block 8. The end of the contact block 8 is in contact with the outer wall of the pipe, and the contact block 8 can move up and down. A pull rope is installed between the contact block 8 and the stop block 6. When the crane 20 lifts the pipe (by binding the center of the pipe with an auxiliary device), if the pipe tilts to both ends, one end of the pipe will tilt upwards, pushing the contact block 8 upwards and pulling the rope, causing the stop block 6 to move outwards (along the length of the pipe). The stop block 6 restricts the pipe and reduces the degree of tilt, thus ensuring the stability and safety of the pipe during lifting. Below the mounting block 1, there is a rubber elastic pad 3 with a gas-filled groove inside.

[0040] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 6 A pressure roller 7 is provided below the stop block 6; a slot is provided at the connection between the stop block 6 and the pressure roller 7, and the mounting frame of the pressure roller 7 is slidably inserted into the slot. A spring is provided between the slot and the mounting frame of the pressure roller 7; the stop block 6 can restrict the pipe and prevent the pipe from deforming by contacting the pressure roller 7 with the top of the pipe.

[0041] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 3 The insert 12 is equipped with a telescopic sleeve 13, which is fitted over the outside of the binding rope 11. The telescopic sleeve 13 is a multi-stage telescopic sleeve, specifically consisting of multiple sets of pipes that are sequentially slidably fitted together (i.e., the second pipe slides onto the first pipe, the third pipe slides onto the second pipe, and so on). By extending the telescopic sleeve 13, the worker holds the end of the telescopic sleeve 13 and passes the insert 12 through the bottom of the pipe (because the binding rope 11 is soft, if the insert 12 passes directly through the bottom of the pipe, it will sag, making it inconvenient for the insert 12 to pass through the pipe and to reach the other side from the bottom of the pipe). This prevents the insert 12 from sag and makes it easier for the worker to insert the insert 12 into the slot 51.

[0042] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 4A connector 14 (made of flexible plastic) is slidably provided on the fixing member 5. A magnet 15 is provided on the connector 14, and the insert 12 is a magnetic block. During the process of the insert 12 passing under the pipe, the connector 14 is moved to make the magnet 15 and the insert 12 stick together and attract them together. Pulling the connector 14 can pull the insert 12 out from under the pipe, making it easy to pass the insert 12 under the pipe and make it easy to tie the binding rope 11 to the outside of the pipe.

[0043] In this embodiment, as a further optimization, please refer to... Figure 5 and Figure 6 The movable slot 17 is equipped with a touch switch 18, and the mounting slot 16 is equipped with an electromagnet. The electromagnet is electrically connected to the touch switch 18 through a wire. The side of the stop block 6 facing the electromagnet is equipped with a magnet, and the magnetic poles of the magnet and the electromagnet are the same on the side that are close to each other. When the pipe tilts and moves the contact block 8 on one side upward, the upward movement of the contact block 8 will also increase as the tilt of the pipe increases. This will cause the contact block 8 to press the touch switch, which will energize the electromagnet and generate a magnetic force that repels the magnet. This will push the stop block 6 to move outward, increasing the contact area between the stop block 6 and the pipe, thereby preventing the pipe from tilting and increasing the ability of the stop block 6 to prevent the pipe from tilting.

[0044] A method for installing large-size pipes on a pipe rack module, utilizing an auxiliary device for this installation, specifically includes the following steps:

[0045] Please see Figure 7 and Figure 8 S1: Install full-span scaffolding 21 under the crossbeam of the first floor of the pipe gallery module 19 where large-sized pipes will be installed, and set up two cranes 20 on both sides of the same end of the pipe gallery module 19.

[0046] Please see Figure 7 and Figure 8 S2: Use an auxiliary device to secure the center of the pipe and hang the auxiliary device on one of the cranes 20. Use the crane 20 to place one end of the pipe flat on the crossbeam of the pipe gallery module 19 and make one end of the pipe extend beyond the crossbeam by a certain distance (the crossbeam refers to e, f, g, h, i).

[0047] Please see Figure 8 , Figure 9 and Figure 10 S3: Use an auxiliary device to tie the outer end of the pipe, then use another crane 20 to connect to the auxiliary device, then remove the auxiliary device at the center of the pipe and tie it to the inner end of the pipe. Then, the two cranes 20 lift the pipe at the same time and move it horizontally to the two crossbeams of the pipe gallery module 19.

[0048] Please see Figure 10 and Figure 11 S4: Remove the auxiliary device on the pipeline and re-tie the auxiliary device to the pipeline. Then, use two cranes 20 to move the pipeline inward to the inside of the pipe gallery module 19.

[0049] The specific method for the auxiliary device to bind the pipe is as follows: place the mounting block 1 above the pipe, then pull the insert block 12 to release the binding rope 11 from the outer wall of the rotating rod 10 and wrap the binding rope 11 around the outside of the pipe. Then insert the insert block 12 into the slot 51 of the fixing member 5 and hang the lifting ring on the hook of the crane 20.

[0050] Please see Figure 12 When the pipe is placed on the crossbeam, two sets of wooden wedges 22 are installed on the crossbeam and positioned on both sides of the pipe to prevent the pipe from sliding left and right on the crossbeam.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
