Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and in particular to a method and equipment for installing pipelines in an overhead pipe gallery. Background Art

[0002] When constructing pipelines in an overhead pipe gallery, usually two sections of pipelines are pre-spot welded first, and then a crane is used to hoist and place the pipelines at the pre-installation positions of the two sections of pipelines on the overhead pipe gallery. During the hoisting process, hoisting equipment such as a chain block is required to assist in hoisting and positioning. After hoisting, in order to facilitate subsequent welding operations, a welding operation platform also needs to be erected at the position corresponding to the welding joint of the two sections of pipelines on the periphery of the overhead pipe gallery, and then the welding of the remaining welds is completed on the welding operation platform. By repeating the above processes of spot welding, hoisting, erecting the platform, and welding, all the pipelines in the pipeline can be welded in sequence, thus completing the pipeline construction.

[0003] However, the overhead pipe gallery and pipelines are usually long. When constructing using the existing pipeline construction method, it is necessary to frequently change the crane standing positions and erect multiple scaffolding operation platforms for construction. And the crane standing positions have relatively high requirements for the foundation conditions of the construction site, and it is necessary to ensure that the crane standing position site is flat. For areas where the bearing capacity does not meet the requirements of the crane standing position, additional compaction and other treatment work are also required. Therefore, when constructing using the existing pipeline construction method, the construction process is complex, a large amount of manpower and mechanical equipment are required during the whole construction process, the construction cost is relatively high, and the efficiency is relatively low.

[0022] In a second aspect, the present invention provides an overhead pipe gallery pipeline installation device, which applies the overhead pipe gallery pipeline installation method according to any one of the foregoing embodiments, and includes a construction operation platform and a conveying device;

[0023] The construction operation platform is fixed to one side of the overhead pipe gallery and is used to support the pipes in the pipeline to be constructed; the conveying device is used to drive the pipes to move along the extension direction of the overhead pipe gallery.

[0024] The overhead pipe gallery pipeline installation method provided by the present invention includes: S1: Build a construction operation platform on one side of the overhead pipe gallery, and place the pipes in the pipeline to be constructed on the construction operation platform; S2: Transfer two of the pipes on the construction operation platform to the overhead pipe gallery, and butt-weld one end of the two pipes on the construction operation platform to form a welded group; S3: Use the conveying device to drive the welded group to move along the extension direction of the overhead pipe gallery, so as to leave a pipe vacancy at the position of the overhead pipe gallery opposite to the construction operation platform; S4: Transfer one of the pipes on the construction operation platform to the pipe vacancy, and butt-weld the pipe to the pipe in the welded group close to the pipe vacancy on the construction operation platform to form a new welded group; S5: Repeat step S3-step S4 until the welding operation of all the pipes in the pipeline is completed. The overhead pipe gallery pipeline installation method provided by the present invention is used in the pipeline construction process in the overhead pipe gallery. During construction, first, according to step S1, a construction operation platform can be built on one side of the overhead pipe gallery, and multiple sections of pipes used for butt-welding to form a pipeline can be hoisted onto the construction operation platform. At this time, only the crane standing position needs to be arranged at the construction operation platform. Then, according to step S2, the construction workers can transfer two pipes from the construction operation platform to the overhead pipe gallery and butt-weld the two pipes to form a welded group. Since the construction operation platform is located on one side of the overhead pipe gallery, the construction workers can realize the above pipe transfer and welding process at this time, and the welded group formed after welding is located at the position of the overhead pipe gallery opposite to the construction operation platform.

After leaving the pipe vacancy, then according to step S4, the construction workers on the construction operation platform transfer the next pipe to the overhead pipe gallery and butt-weld the next pipe to the pipe in the aforementioned welded group close to the pipe vacancy, thereby forming a new welded group. Then, in step S5, repeat the above step S3-step S4, and realize the welding operation of all the pipes in the pipeline by continuously moving the welded group and the welding pipes. At the same time, the pipeline can also be moved into place after all the pipes are welded by continuously moving the welded group, so that the pipeline is distributed in the overhead pipe gallery without further adjusting the position of the pipeline. Among them, the conveying device can be installed on the ground, and at this time, the conveying device can adopt a traction device; or, the conveying device can also be installed in the overhead pipe gallery, and at this time, the conveying device can adopt a telescopic driving device, a sliding device, etc. Correspondingly, when placing the pipe in the overhead pipe gallery, the pipe needs to be placed on the conveying device.

[0025] Compared with the prior art, the overhead pipe gallery pipeline installation method provided by the present invention enables construction workers to complete the welding process of all pipelines in the pipeline on the construction operation platform on one side of the overhead pipe gallery by using a conveying device.

[0037] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0038] Embodiment:

[0039] As Figure 1 shown, the method for installing the pipeline of the overhead pipe gallery provided by this embodiment includes:

[0040] Step S1: Build a construction operation platform 2 on one side of the overhead pipe gallery 1, and place the pipeline 3 in the pipeline to be constructed on the construction operation platform 2;

[0041] Step S2: Transfer two of the pipelines 3 on the construction operation platform 2 to the overhead pipe gallery 1, and butt-weld one end of the two pipelines 3 on the construction operation platform 2 to form a welding group;

[0042] Step S3: Use the transmission device 4 to drive the welding group to move along the extension direction of the overhead pipe gallery 1, so as to leave a pipeline 3 vacancy at the position of the overhead pipe gallery 1 opposite to the construction operation platform 2;

[0043] Step S4: Transfer one of the pipes 3 on the construction platform 2 to the vacant position of the pipe 3, and butt-weld the pipe 3 with the pipe 3 in the welding group close to the vacant position of the pipe 3 on the construction platform 2 to form a new welding group;

[0044] Step S5: Repeat Step S3 - Step S4 until the welding operation of all the pipes 3 in the pipeline is completed.

[0045] The overhead pipe gallery pipeline installation method provided in this embodiment is used for the pipeline construction process in the overhead pipe gallery 1. During construction, the construction platform 2 can be first built on one side of the overhead pipe gallery 1 according to Step S1, and multiple sections of pipes 3 used for butt-welding to form the pipeline are hoisted onto the construction platform 2. At this time, only the crane standing position needs to be arranged at the construction platform 2. The structures of the pipe 3, the construction platform 2, and the conveying device 4 are as Figure 2 shown. Then, according to Step S2, the construction workers can transfer two pipes 3 into the overhead pipe gallery 1 on the construction platform 2 and butt-weld the two pipes 3 to form a welding group. Since the construction platform 2 is located on one side of the overhead pipe gallery 1, the construction workers can realize the above-mentioned pipe 3 transfer and welding process at this time, and the welding group formed after welding is located at the position of the overhead pipe gallery 1 opposite to the construction platform 2.

[0046] The overhead pipe gallery pipeline installation method provided in this embodiment can be applied to the overhead pipe gallery 1 in Figures 3 - 5 shown by the overhead pipe gallery pipeline installation equipment as Figures 3 - 5 above. As shown in Figure 3 and Figure 4 shown, the overhead pipe gallery 1 generally includes a plurality of columns 10 spaced at intervals along its extending direction and cross beams 11 fixed to the tops of the columns 10. When placing the pipe 3 in the overhead pipe gallery 1, the pipe 3 can be placed on the cross beams 11 to support the pipe 3 by using the cross beams 11.

[0047] After completing the pipe 3 welding process in Step S2 and forming a welding group, then start according to Step S3 Figure 2 and Figure 3The shown conveying device 4 drives the welding group to move along the extending direction of the overhead pipe gallery 1 until a pipe 3 vacancy sufficient to accommodate the next pipe 3 is left at the position of the overhead pipe gallery 1 opposite to the construction operation platform 2. After leaving the pipe 3 vacancy, then according to step S4, the construction workers on the construction operation platform 2 transfer the next pipe 3 into the overhead pipe gallery 1 and butt-weld the next pipe 3 with the pipe 3 in the aforementioned welding group close to the pipe 3 vacancy, thereby forming a new welding group. Then in step S5, repeat the above steps S3 - step S4, and realize the welding operation of all the pipes 3 in the pipeline by continuously moving the welding group and welding the pipes 3. At the same time, the pipeline can also be moved into place after completing the welding operation of all the pipes 3 by continuously moving the welding group, so that the pipeline is distributed in the overhead pipe gallery 1 without further adjusting the position of the pipeline.

[0048] Among them, as Figure 3 shown, the conveying device 4 can be installed on the ground. At this time, the conveying device 4 can adopt a traction device; or, the conveying device 4 can also be installed in the overhead pipe gallery 1. At this time, the conveying device 4 can adopt devices such as a telescopic driving device, a sliding device, a conveying chain, etc. Correspondingly, when placing the pipe 3 in the overhead pipe gallery 1, the pipe 3 needs to be placed on the conveying device 4.

[0049] Compared with the prior art, the method for installing the pipeline in the overhead pipe gallery provided in this embodiment enables the construction workers to complete the welding process of all the pipes 3 in the pipeline on the construction operation platform 2 on one side of the overhead pipe gallery 1 by adopting the conveying device 4, and after completing the welding operation of all the pipes 3, the pipeline can be distributed in place in the overhead pipe gallery 1. There is no need to set up multiple crane standing positions along the extending direction of the overhead pipe gallery 1 to arrange multiple sections of pipes 3 in sequence along the pipe gallery direction, nor is it necessary to set up multiple scaffolding operation platforms along the extending direction of the overhead pipe gallery 1 to weld the adjacent two pipes 3 in sequence. Thus, the pipeline construction process is greatly simplified, the construction efficiency is improved, at the same time, the input of manpower and mechanical equipment is effectively reduced, the construction cost and construction safety risk are reduced. In addition, the coordination and management difficulty of the construction site can be significantly reduced.

[0050] It should be noted that after completing the construction of the overhead pipe gallery 1 and before carrying out the pipeline construction, as Figure 2 shown, it is also possible to pre-divide a transportation vehicle parking area and a crane standing area 5 at a position on the ground close to the construction operation platform 2 in advance. The transportation vehicle parking area is used to park the transportation vehicles for transporting the pipes 3, and the crane standing area 5 is used to set up lifting equipment such as cranes to facilitate the pipe 3 lifting operation. During the pipeline construction process, in order to reduce the safety risk caused by the lifting operation, based on the daily construction progress and the demand for construction materials, in step S1, all the pipes 3 required for the construction on the current day can be lifted onto the construction operation platform 2 before proceeding to step S2.

[0051] It should also be noted that, for the convenience of the pipeline 3 to be distributed in place in the overhead pipe gallery 1 after welding, as Figure 2 shown, in this embodiment, the construction operation platform 2 is preferably arranged at one end of the overhead pipe gallery 1. Among them, the construction operation platform 2 can adopt brackets such as scaffolding, and the top of the bracket is provided with a top plate for supporting construction workers, construction materials and construction tools.

[0052] Among them, there are various choices for the conveying device 4, and its structure is not limited, as long as it can drive the pipeline 3 to move in the overhead pipe gallery 1. As Figures 2 - 4 shown, in this embodiment, the conveying device 4 preferably includes a traction assembly 40, and the traction assembly 40 is used to connect with the pipeline 3 in the welding group far from the construction operation platform 2 and drive the welding group to move along the extension direction of the overhead pipe gallery 1.

[0053] Specifically, the traction assembly 40 can adopt a winch. As Figure 3 shown, the traction assembly 40 can be placed on the ground and on one side of the end of the overhead pipe gallery 1 far from the construction operation platform 2. When the traction assembly 40 is started, it can pull the welding group to move away from the construction operation platform 2 along the extension direction of the overhead pipe gallery 1 through a rope, so as to realize the movement process of the pipeline 3 on the cross beam 11 of the overhead pipe gallery 1.

[0054] Furthermore, as Figure 2 and Figure 3 shown, the conveying device 4 further includes a conveying assembly 41. The conveying assembly 41 is installed on the overhead pipe gallery 1 and is used to support the pipeline 3 and assist the pipeline 3 to move along the extension direction of the overhead pipe gallery 1.

[0055] The conveying assembly 41 is installed on the cross beam 11 of the overhead pipe gallery 1. When placing the pipeline 3 in the overhead pipe gallery 1, that is, placing the pipeline 3 on the conveying assembly 41. Among them, the conveying assembly 41 can adopt structures such as slide rails and pulleys. At this time, the conveying assembly 41 can not only support the pipeline 3 to improve the stability of the pipeline 3, but also reduce the friction between the pipeline 3 and the cross beam 11 of the overhead pipe gallery 1, thereby improving the smoothness of the movement process of the pipeline 3 in the overhead pipe gallery 1.

[0056] It can be seen that compared with the process of only using the traction assembly 40 to pull the pipeline 3 to move, using the cooperation of the conveying assembly 41 and the traction assembly 40 to realize the movement process of the pipeline 3 in the overhead pipe gallery 1 can improve the smoothness of the movement process of the pipeline 3, thereby improving the construction efficiency. At the same time, it can reduce the friction between the pipeline 3 and the cross beam 11 of the overhead pipe gallery 1 and reduce the surface scratches of the pipeline 3.

[0057] It should be noted that after the pipeline construction is completed, the conveying component 41 can be fixed in the overhead pipe gallery 1 without disassembly. At this time, only the traction component 40 needs to be separated from the pipeline 3 and the traction component 40 is recycled.

[0058] In addition, the installation process of the conveying component 41 can be carried out synchronously during the construction process of the overhead pipe gallery 1. For example, the conveying component 41 is fixed on the cross beam 11 before the cross beam 11 in the overhead pipe gallery 1 is fixed to the column 10, so that after the installation of the cross beam 11 is completed, the conveying component 41 is installed on the cross beam 11. Compared with the installation process of the conveying component 41 after the construction of the overhead pipe gallery 1 is completed, the construction difficulty can be effectively simplified, thereby improving the construction efficiency.

[0059] It should also be noted that in practical applications, if the position of the pipeline still needs to be adjusted after the welding operation of the pipeline 3 in the pipeline is completed, at this time, the traction component 40 and the conveying component 41 can be used in cooperation to continue to adjust the position of the pipeline in the overhead pipe gallery 1. Compared with the existing pipeline construction process of calibrating the position of the pipeline 3 at any time, the construction steps can also be simplified and the construction efficiency can be improved.

[0060] As Figure 2 and Figure 3 shown, in this embodiment, the traction component 40 preferably includes a traction driving member 400, a traction rope 401 and a fixed pulley 402; the traction driving member 400 is fixed on the ground, one end of the traction rope 401 is connected to the output end of the traction driving member 400, and the other end is connected to the pipeline 3 far from the construction platform 2 in the welding group; the fixed pulley 402 is installed at a position in the overhead pipe gallery 1 far from the construction platform 2, and the traction rope 401 is wound around the fixed pulley 402.

[0061] Among them, the traction driving member 400 can adopt a motor, and the traction driving member 400 and the traction rope 401 together form a winch. The fixed pulley 402 can support the traction rope 401 and play a guiding role for the traction rope 401 at the same time, effectively improving the stability and smoothness of the process of the traction component 40 pulling the pipeline 3 to move, avoiding damage due to excessive tension of the traction rope 401, and avoiding damage to the cross beam 11 due to the traction rope 401 overlapping with the cross beam 11 in the overhead pipe gallery 1.

[0062] Among them, the fixed pulley 402 can be fixed to the cross beam 11 of the overhead pipe gallery 1 by welding or by bolts, and the fixed pulley 402 can be recycled after the pipeline construction is completed.

[0063] As Figure 3 and Figure 6 shown, the conveying component 41 includes rolling members 410, and the rolling members 410 are used for rotating self when the pipeline 3 moves along the extension direction of the overhead pipe gallery 1; and there are multiple conveying components 41, and the multiple conveying components 41 are distributed in sequence along the extension direction of the overhead pipe gallery 1.

[0064] The rolling member 410 can be driven to rotate by the pipeline 3 during the movement of the pipeline 3 along the extending direction of the overhead pipe gallery 1, so as to convert the sliding friction between the pipeline 3 and the cross beam 11 of the overhead pipe gallery 1 into rolling friction, and further improve the smoothness of the movement process of the pipeline 3.

[0065] When there are multiple conveying components 41, the multiple conveying components 41 can cooperate with each other to stably support the pipeline 3 in the welding group. In this embodiment, a conveying component 41 can be installed on each cross beam 11 of the overhead pipe gallery 1. Correspondingly, at this time, the multiple conveying components 41 are distributed in sequence along the extending direction of the overhead pipe gallery 1.

[0066] Furthermore, near the construction operation platform 2, the distance between two adjacent conveying components 41 in the overhead pipe gallery 1 can be less than the distance between two adjacent conveying components 41 far from the construction operation platform 2. Specifically, the distance between two adjacent conveying components 41 near the construction operation platform 2 can be 3 meters, and the distance between two adjacent conveying components 41 far from the construction operation platform 2 can be 6 meters. Among them, the 3-meter distance is used to meet the stability of the pipeline 3 on the conveying component 41 during the welding process of the pipeline 3, while the 6-meter distance is used to meet the requirement of the pipeline deformation amount after the pipeline length gradually increases during the construction process, so that the pipeline deformation amount is minimized, thereby ensuring that the pipeline 3 is not affected by its deformation during the conveying process.

[0067] Among them, the rolling member 410 can be a horizontal roller. At this time, there can be multiple rolling members 410 in each conveying component 41. The multiple rolling members 410 are distributed in sequence along the extending direction of the pipeline 3, and the axial direction of each rolling member 410 is perpendicular to the extending direction of the pipeline 3.

[0068] As Figure 6 shown, the conveying component 41 can further include an upper support 411. The multiple rolling members 410 are all rotatably installed on the upper support 411, and the upper support 411 is fixed on the cross beam 11 of the overhead pipe gallery 1.

[0069] At this time, to further improve the stability of the movement process of the pipeline 3, as Figure 6 shown, a limiting roller 412 can also be rotatably installed on the upper support 411. There are two groups of limiting rollers 412, and the two groups of limiting rollers 412 are respectively distributed on both sides of the pipeline 3 on the rolling member 410, and the shaft body of the limiting roller 412 abuts against the pipeline 3, so that the limiting roller 412 is driven to rotate during the movement of the pipeline 3 along the extending direction of the overhead pipe gallery 1.

[0070] It can be seen that the limiting roller 412 can limit the pipeline 3 to prevent the pipeline 3 from shifting in position during transmission, thus ensuring the smooth transmission of the pipeline 3. At the same time, the limiting roller 412 can rotate automatically driven by the pipeline 3 during the movement of the pipeline 3, effectively reducing the friction between it and the pipeline 3.

[0071] As Figure 6 shown, to improve the limiting effect of the limiting roller 412, in this embodiment, it is preferred that one end of the limiting roller 412 is higher than the other end so that the limiting roller 412 is inclined relative to the horizontal plane, and the limiting roller 412 is inclined in the direction away from the central axis of the pipeline 3 on the rolling member 410 from its lower end to its higher end. At this time, an included angle is formed between the two groups of limiting rollers 412, and the pipeline 3 on the rolling member 410 is located in the above-mentioned included angle, and the two groups of limiting rollers 412 can cooperate with each other to further improve the stability of the movement process of the pipeline 3.

[0072] Among them, the upper support 411 can include a bottom plate and side plates fixed to both sides of the bottom plate. Two groups of opposing support plates are provided on the bottom plate, and the horizontal roller is rotatably installed between the two groups of support plates; the limiting roller 412 is rotatably installed between the bottom plate and the side plates.

[0073] To improve the structural stability of the upper support 411, a reinforcing plate can also be fixed between the side plate and the bottom plate, and a reinforcing plate can also be fixed between the support plate and the bottom plate.

[0074] As Figure 6 shown, the transmission assembly 41 provided in this embodiment can also include a lower support 413. The lower support 413 is fixed below the upper support 411, and the lower support 413 is used to be fixed on the cross beam 11 of the overhead pipe gallery 1.

[0075] Among them, there are various choices for the structure of the lower support 413. To improve the connection convenience between the transmission assembly 41 and the cross beam 11 of the overhead pipe gallery 1, in this embodiment, it is preferred that the lower support 413 is a trough-shaped structure with an opening facing downwards, and a tightening bolt is threadedly connected to the side wall of the lower support 413. When installing the lower support 413 on the cross beam 11 of the overhead pipe gallery 1, the lower support 413 can be first sleeved on the cross beam 11, and then the tightening bolt can be screwed so that the end of the tightening bolt located in the space inside the trough of the lower support 413 abuts against the side wall of the cross beam 11, thereby fixing the lower support 413 on the cross beam 11.

[0076] Further, as Figure 6As shown in the figure, a limiting screw can also be provided on the lower support 413. The limiting screw is threadedly connected between two side walls of the lower support 413 with opposite positions, and the limiting screw is located below the tightening bolt. Before covering the lower support 413 on the cross beam 11, the limiting screw can be detached from the lower support 413. After covering the lower support 413 on the cross beam 11, the limiting screw is threadedly connected between two side walls of the lower support 413 with opposite positions, so that the limiting screw is located below the cross beam 11, thereby limiting the lower support 413 at the cross beam 11 and further improving the installation stability of the conveying assembly 41 at the cross beam 11.

[0077] As Figure 2 and Figure 3 shown, when constructing the construction operation platform 2 in step S1, storage areas 20, alignment areas 21, tack welding areas 22 and welding areas 23 can be provided on the construction operation platform 2 in sequence along the extending direction of the overhead pipe gallery 1; among them, the storage area 20 is used for temporarily storing the pipes 3, the alignment area 21 is used for supporting the construction workers to butt the adjacent ends of two pipes 3, the tack welding area 22 is used for supporting the construction workers to perform tack welding operations on the pipes 3, and the welding area 23 is used for supporting the construction workers to perform welding operations on the pipes 3.

[0078] The conveying device 4 provided in this embodiment can also drive the pipe 3 to move between the storage area 20, the alignment area 21, the tack welding area 22 and the welding area 23, so as to facilitate the processes of aligning, tack welding and welding the pipe 3 in sequence.

[0079] It can be seen that by providing the storage area 20, the alignment area 21, the tack welding area 22 and the welding area 23 on the construction operation platform 2 in sequence along the extending direction of the overhead pipe gallery 1, the storage area 20 of the pipe 3 can be separated from the operation areas of the construction workers, thus facilitating the orderly progress of the construction operations. Moreover, since the operation areas on the construction operation platform 2 include the alignment area 21, the tack welding area 22 and the welding area 23 in sequence along the extending direction of the overhead pipe gallery 1, the processes of aligning, tack welding and welding the pipe 3 can be carried out by different groups of construction workers respectively at this time. This can not only further make the construction operations more orderly, but also improve the operation efficiency through the mutual cooperation of each group of construction workers.

[0080] Among them, when butt-welding the pipes 3, the adjacent ends of two pipes 3 can be beveled first, and then the position of the pipe 3 can be adjusted by the rolling action of the conveying assembly 41 to butt the adjacent ends of the two pipes 3, and ensure that the interval between the adjacent ends of the two pipes 3 reaches the interval required for welding. To keep the interval between the adjacent ends of the two pipes 3 fixed, the adjacent two ends of the pipe 3 can also be fixedly connected by a clamp 6. Based on this, when connecting the towing rope 401 of the towing assembly 40 to the pipe 3 in the welding group, the clamp 6 between the towing rope 401 and the pipe 3 in the welding group can be connected, so as to ensure the connection stability between the pipe 3 and the towing rope 401 and reduce the damage to the pipe 3 at the same time.

[0081] To facilitate the transfer of the pipes 3 in the storage area 20 to the overhead pipe gallery 1, the storage area 20 can be flush with the bottom of the overhead pipe gallery 1, that is, the elevation of the storage area 20 can be the same as the elevation of the cross beam 11 of the overhead pipe gallery 1; and to facilitate the construction workers to carry out butt-welding, tack-welding and welding operations on the pipes 3, the butt-welding area 21, the tack-welding area 22 and the welding area 23 can all be lower than the bottom of the overhead pipe gallery 1, that is, the elevations of the butt-welding area 21, the tack-welding area 22 and the welding area 23 are all lower than the elevation of the cross beam 11 of the overhead pipe gallery 1.

[0082] To further improve the construction convenience of the construction workers on the construction platform 2, in this embodiment, it is preferably that the elevations of the butt-welding area 21, the tack-welding area 22 and the welding area 23 are all 0.8 meters lower than the elevation of the cross beam 11 of the overhead pipe gallery 1.

[0083] In addition, to ensure that the construction workers have sufficient construction space, in this embodiment, it is preferably that the length and width of the butt-welding area 21 are both 2 meters, the length and width of the welding area 23 are also both 2 meters, and the tack-welding area 22 can share an area with the butt-welding area 21.

[0084] It should also be noted that when the length of the overhead pipe gallery 1 is relatively long, to further improve the construction efficiency, when building the construction platform 2 in step S1, as Figure 4 shown, a plurality of construction platforms 2 can be arranged on one side of the overhead pipe gallery 1, and the plurality of construction platforms 2 are spaced apart along the extending direction of the overhead pipe gallery 1.

[0085] Furthermore, the distance between two adjacent construction platforms 2 can be no more than 120 meters.

[0086] When there are multiple construction platforms 2, a plurality of towing assemblies 40 in the conveying device 4 can also be correspondingly arranged. As Figure 4 shown, at this time, the towing assembly 40 between the two ends of the overhead pipe gallery 1 can be arranged on the construction platform 2, and further, it can be arranged on the storage area 20 of the construction platform 2.

[0087] As Figure 5 shown, when there are multiple corners in the overhead pipe gallery 1, in this embodiment, it is preferred that there are multiple construction operation platforms 2. The multiple construction operation platforms 2 are spaced along the extension direction of the overhead pipe gallery 1, and a construction operation platform 2 is provided at each corner of the overhead pipe gallery 1.

[0088] Setting the construction operation platform 2 at the corner of the overhead pipe gallery 1 facilitates the segmented construction of the pipelines in the overhead pipe gallery 1 and prevents the pipeline 3 from being difficult to pass through the corner and affecting the construction progress.

[0089] In this embodiment, a remote control component may be provided on the construction operation platform 2. The remote control component is used to send start / stop instructions to the conveying device 4 to control the start / stop of the conveying device 4.

[0090] When a remote control component is provided on the construction operation platform 2, the construction personnel on the construction operation platform 2 can send start / stop instructions to the construction personnel for starting and stopping the conveying device 4.

[0091] When the butt-welding area 21 and the tack-welding area 22 share the same area, to further improve the construction efficiency, the distance between the butt-welding area 21 and the welding area 23 can also be designed according to the length of the pipeline 3. Thus, when the construction personnel control the start / stop of the conveying device 4 through the remote control component, when one end of the pipeline 3 reaches the welding area 23, the other end of the pipeline 3 is in the butt-welding area 21, preparing for the butt-welding process of the next section of the pipeline 3.

[0092] As Figures 3 - 5 shown, this embodiment also provides an overhead pipe gallery pipeline installation device. This overhead pipe gallery pipeline installation device applies the above-mentioned overhead pipe gallery pipeline installation method, and it includes a construction operation platform 2 and a conveying device 4; the construction operation platform 2 is fixed on one side of the overhead pipe gallery 1 and is used to support the pipeline 3 in the pipeline to be constructed; the conveying device 4 is used to drive the pipeline 3 to move along the extension direction of the overhead pipe gallery 1. Since the overhead pipe gallery pipeline installation device provided in this embodiment applies the above-mentioned overhead pipe gallery pipeline installation method, this overhead pipe gallery pipeline installation device and the above-mentioned overhead pipe gallery pipeline installation method can solve the same technical problems and achieve the same technical effects, and will not be elaborated here.

[0093] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
