Description

Technical Field

[0001] The present invention provides a device and method for road piping that can reduce equipment movement time, reduce the road width occupied by equipment, and reduce the complexity of hoisting operations. Prior Technology

[0002] In current water pipe installation projects, high-density polyethylene (HDPE), known for its corrosion resistance and long lifespan, is commonly used as the pipe material. However, as shown in Figures 1 and 2, which are schematic diagrams of conventional road piping (I) and (II), due to the large weight and length of the HDPE pipe 91, a large crane 92 is usually required to move the pipe 91 to the pipe trench 911 for positioning and installation. This process is not only costly but also requires a lot of space. Especially when the pipe 91 needs to be moved to narrow or busy urban roads for construction, it will occupy several lanes, greatly impacting traffic.

[0003] Especially in areas with high groundwater levels, the trench 911 often accumulates a lot of water, making it impossible to perform welding operations within the trench 911. Therefore, in existing technologies, it is usually necessary to weld the pipe 91 next to the trench 911 before using a crane 92 to lower the connected pipe 911 into the trench 911. Since the welding equipment 93 and crane 92 need to be moved frequently as the pipe location changes, each relocation requires a significant amount of manpower and time, increasing construction difficulty and extending the construction period. Furthermore, the frequent relocation of the welding equipment 93 and crane 92 at the construction site leads to low equipment operation and usage efficiency, further increasing construction costs and environmental impact.

[0004] The current construction method involves welding work next to the pipe trench 911, which typically requires occupying three to four lanes to place construction equipment and materials. In order to ensure construction safety and efficiency, the entire process requires the use of multiple cranes 92 and welding equipment 93, occupying a large amount of construction space and affecting traffic flow. If construction is carried out in busy road sections, it often causes traffic jams, putting great pressure on urban traffic.

[0005] Therefore, current HDPE pipe laying technology is inefficient in terms of handling, welding, and moving construction equipment, and the construction process has a significant impact on traffic, especially in construction environments with high groundwater levels, where pipe handling and installation are even more challenging. How to optimize handling and welding methods to reduce the need for cranes and shorten equipment movement time, thereby reducing the impact of construction on traffic, is the direction that the applicant of this invention and related manufacturers in this industry are eager to research and improve. Summary of the Invention

[0006] Therefore, in view of the above-mentioned deficiencies, the applicant of this invention collected relevant information, conducted multiple evaluations and considerations, and, based on years of experience accumulated in this industry, and through continuous trial and modification, designed this invention patent holder for a road piping device and method that can reduce equipment movement time, reduce the road width occupied by equipment, and reduce the complexity of hoisting operations.

[0007] The main objective of this invention is to combine the conveying device and the welding device on a mobile platform, so that the welding device can be fixed in one place without disassembly and assembly, shortening the equipment movement time. Furthermore, since the mobile platform is set along the direction of the pipeline laying, it can reduce the traffic impact caused by construction land occupation, and also reduce the requirements for the strength, quantity and operation difficulty of the suspended equipment.

[0008] To achieve the above objectives, the structure of the present invention includes: a mobile platform, a plurality of conveying devices, at least one sliding part, a welding device, and at least one suspension device including a control element and a lifting claw. The mobile platform moves along the extension direction of the pipeline, the conveying devices are arranged at intervals on the mobile platform, the sliding part is used to support and convey the plurality of pipes, the welding device is located on the mobile platform and on one side of any conveying device so that each pipe can be welded on the mobile platform, and the lifting claw is connected to the control element and moves vertically above the trench of the pipeline.

[0009] When users utilize this invention for road piping construction, a mobile platform is first installed along the extension direction of the pipeline. Multiple conveying devices are arranged at intervals on the mobile platform, and their sliding parts support and convey the pipes. A welding device is then installed on the mobile platform, allowing each pipe to be welded on the platform. Next, a suspension device is used to move the welded pipe from the end of the conveying device to the trench where the pipeline is to be laid. Then, a control element drives the lifting claw to vertically lift and lower the pipe above the trench to place it into the trench. In this way, since the equipment is all set along the direction of the pipeline, the road area occupied is smaller. The welding and conveying devices are also set on the mobile platform, saving time and manpower from frequent disassembly and assembly of equipment. The suspension device's hanging action is simpler and safer, with lower requirements for strength and quantity. After some pipes are placed into the trench, the mobile platform can be slowly moved backward, allowing the pipes to slide naturally into the trench using the material properties, significantly shortening the construction period.

[0010] The above-mentioned technologies can overcome the problems of low mobility of construction equipment, significant impact on traffic during construction, and high requirements for hanging strength in conventional pipeline laying technologies, thus achieving the practical and progressive advantages mentioned above.

[0012] To achieve the above objectives and effects, the technical means and structure adopted in this invention are described in detail below with reference to the first preferred embodiment of the invention, so as to facilitate a complete understanding.

[0013] Please refer to Figures 3 through 10, which are perspective views and flowcharts illustrating the steps of the first preferred embodiment of the present invention. The figures clearly show that the present invention includes:

[0014] A mobile platform 1 moves along the extension direction of the pipeline laying;

[0015] The multiple conveying devices 2 are arranged at intervals on the moving platform 1, and include at least one sliding part 21 for supporting and conveying multiple tubes 7, and two limiting parts 22 provided at both ends of the sliding part 21;

[0016] A transmission element 3 is disposed on one side of the front end of the conveying device 2 to drive each of the tubes 7 to move;

[0017] A welding device 4 is mounted on the moving platform 1 and located on one side of any of the conveying devices 2, so that each of the tubes 7 can be welded on the moving platform 1;

[0018] At least one suspension device 5 includes a control element 51 and a lifting claw 52 connected to the control element 51, and the lifting claw 52 is vertically raised and lowered above the pipe trench 8 where the pipeline is laid; and

[0019] A plurality of support seats 6 are arranged at intervals across the trench 8, and each support seat 6 is simultaneously provided with the conveying device 2, and has a plurality of auxiliary wheels 61.

[0020] The road piping method of the present invention includes the following steps:

[0021] (a) Equipment layout: A movable platform 1 is movably installed in the extension direction of the pipeline, and a plurality of conveying devices 2 are arranged at intervals on the movable platform 1;

[0022] (b) Conveying pipe: Each pipe 7 is supported and moved on the sliding part 21 by a transmission element 3;

[0023] (c) Pipe body welding: Using a welding device 4 installed on the moving platform 1, each pipe body 7 is welded on the moving platform 1. If each pipe body 7 in the pipe trench 8 can be fixed in the pipe trench 8, proceed to step (f); otherwise, proceed to step (d).

[0024] (d) Lifting and moving pipes: Using at least one suspension device 5, each of the welded pipes 7 is moved from the end of the conveying device 2 to the trench 8 where the pipeline is laid;

[0025] (e) Lowering the tube body: The suspension device 5 uses a control element 51 to drive a lifting claw 52, ​​which clamps each tube body 7 and vertically lowers it above the trench 8, so as to lower each tube body 7 vertically into the trench 8 without lateral movement. If each tube body 7 can be fixed in the trench 8, proceed to step (f); otherwise, return to step (b); and

[0026] (f) Moving the mobile platform backward: Move the mobile platform 1 away from the trench 8 and along the extension direction of the pipeline, so that each of the welded pipe bodies 7 is lowered into the trench 8, and then return to step (b).

[0027] The pipe body 7 is exemplified by a high-density polyethylene (HDPE) pipe used for tap water pipes; the mobile platform 1 is the trailer of a large flatbed truck; each conveying device 2 is a support structure capable of smoothly carrying heavy objects, and therefore has at least one roller-like sliding part 21. In this embodiment, two are used as an example. In this embodiment, the sliding part 21 has limiting parts 22 at both ends to prevent the pipe body 7 from detaching. The limiting part 22 is exemplified by a columnar structure, and can directly stop on both sides of the sliding part 21, or raise both ends of the sliding part 21 to form a V-shape for limiting. In this embodiment, the latter is used as an example; the transmission element 3 is a mechanism that can drive the pipe body 7 to move on the conveying device 2. The structure includes a crane or a motor driving the sliding part 21. In this embodiment, a crane is used as an example. Of course, if the volume of the pipe body 7 is small, the transmission element 3 can be omitted and manually pushed instead. The welding device 4 is exemplified by a hot-melt butt welding machine. The suspension device 5 is one of a crane, hoist, or overhead crane. In this embodiment, a mobile crane combined with a mobile platform 1 is used as an example. The control element 51 is its manual operation platform or computer control system. The lifting claw part 52 is the part from the steel cable to the hook or gripper. Each support base 6 is a long rod that can provide sufficient support strength. In this embodiment, an H-shaped steel sleeper is used as an example. However, the corresponding forms of the above-mentioned components are only examples of preferred embodiments. Any form with the same function is within the scope of this invention and is not limited to the above examples.

[0028] The above description has provided an understanding of the structure of this technology. Based on the corresponding configuration of this structure, it offers advantages such as reducing equipment movement time, minimizing road width occupied by equipment, and reducing the complexity of hanging operations. As can be clearly seen from the figures, when using this invention for road piping construction, the user simply needs to move the mobile platform 1 along the extension direction of the pipeline. Multiple conveying devices 2 are then arranged at intervals on the mobile platform 1, and their sliding parts 21 support and convey the pipe body 7. Due to the conveying... The device 2 itself does not have power, so a transmission element 3 can be set on one side of the front conveying device 2 to push the pipe 7 to move on the conveying device 2. Then, a welding device 4 is set on the moving platform 1. Specifically, it can be set between two adjacent conveying devices 2. When multiple pipes 7 move close to each other on the conveying device 2, the welding device 4 can make each pipe 7 complete welding on the moving platform 1 and continue to push it to the next conveying device 2. Then, the suspension device 5 is used to move the welded pipe 7 from the end conveying device 2 to the trench 8 where the pipeline is laid.

[0029] Since the pipe body 7 is made of HDPE material, although it is large and heavy, its long length allows for slight bending. Therefore, in this embodiment, a conveying device 2 is simultaneously installed above the trench 8. The device is installed by placing a support base 6, longer than the width of the trench 8, across both sides of the trench 8, and fixing the conveying device 2 to the support base 6. Thus, the height of the conveying device 2 on the moving platform 1 is greater than that on the support base 6, and the height of the conveying device 2 on the support base 6 is greater than the height of the bottom of the trench 8, forming a two-stage height difference, allowing the pipe body... 7 can be lowered in sections. Therefore, the present invention first uses the suspension device 5 to move the front section of the pipe body 7 from the conveying device 2 of the moving platform 1 to the conveying device 2 above the pipe trench 8. Then, the control element 51 drives the lifting claw part 52 to clamp the pipe body 7 (the welded pipe body 7 is hereinafter referred to as the welded pipe body 71) and raise it slightly above the pipe trench 8. As long as the rising height is higher than the conveying device 2, the user can pull the support base 6 together with the conveying device 2 above it. Then, the lifting claw part 52 is controlled to lower vertically to place the welded pipe body 71 into the pipe trench 8.

[0030] Next, since the length of each pipe body 7 is longer after being fused together, as long as the inclination of the fused pipe body 71 from the moving platform 1 to the bottom of the trench 8 is controlled, the fused pipe body 71 can be continuously inserted into the trench 8 without damaging it. Of course, the suspension device 5 is used to slightly raise the fused pipe body 71 to avoid the movement of the conveying device 2. Only the front section of the fused pipe body 71 needs to be raised. For the middle section, as long as the support base 6 and the conveying device 2 above it are removed in sequence before the fused pipe body 71 descends, it can naturally descend into the trench 8 without having to drag the fused pipe body 71 through the suspension device 5. In other words, the suspension device 5 only needs to be operated when the front section of the fused pipe body 71 is inserted into the trench 8, and can be removed afterwards. To reduce road occupancy, the support base 6 can slide using the auxiliary wheels 61 at its bottom when it is removed, reducing the suspension strength required for the removal action. The rear part is the welded pipe body 71 on the moving platform 1. Since a large section of the welded pipe body 71 is already located in the trench 8, at this time, as long as the moving platform 1 is slowly moved away from the trench 8, the welded pipe body 71 on the moving platform 1 will be unable to move back with the moving platform 1 because it is dragged by the welded pipe body 71 in the trench 8. Instead, it will move relative to the conveying device 2 on the moving platform 1 and naturally descend into the trench 8. Therefore, after reaching step (f), the action of conveying the pipe body 7 in step (b) can be repeated.

[0031] In this way, since the mobile platform 1, conveying device 2, suspension device 5, support base 6 and other components are all set along the direction of the pipeline laying, the road occupies only about two lanes, and the area is small. In the best case, only the trench 8 and the mobile platform 1 will occupy the road. The welding device 4 and the conveying device 2 are also set on the mobile platform 1, which can save the time and manpower of frequent disassembly and assembly of equipment. The suspension device 5 has a simple vertical lifting action, which is relatively simple and safe. The strength and quantity requirements are low. After some of the welded pipe body 71 is placed into the trench 8, the mobile platform 1 can be slowly moved backward and naturally slide into the trench 8 by utilizing the material properties of the pipe body 7. This greatly shortens the construction period and indirectly reduces costs and improves equipment utilization efficiency.

[0032] Please refer to Figure 11 for further details. This figure is a schematic diagram of the second preferred embodiment of the present invention. As can be clearly seen from the figure, this embodiment is very similar to the above embodiments, except that the use of the support base is eliminated and the form of the suspension device 5 is changed to a mast crane. This suspension device 5 is referred to as the U-shaped form and is generally used for container lifting. It can be installed on both sides of the conveying device 2 on the mobile platform 1 or move along with the end of the mobile platform 1. Although the cost of use is higher, it can be more easily integrated into the mobile platform 1, hardly occupying the road on both sides, and has a higher load-bearing capacity. It can basically save the installation of the conveying device 2 and the support base above the trench 8, or use fewer suspension devices 5. Therefore, it can be used according to the user's needs. It also shows that the present invention does not limit the form of use of the suspension device 5.

[0033] Please also refer to Figure 12, which is a usage diagram of the third preferred embodiment of the present invention. As can be clearly seen from the figure, this embodiment is very similar to the above embodiments, except that the design of the limiting part is cancelled and the transmission element is changed to the power source of the sliding part 21, such as a motor that drives the sliding part 21. Specifically, the conveying device 2 is changed to the form of a conveyor belt, which uses a large number of sliding parts 21 to support the weight of the tube body 7, avoids the sliding part 21 from bearing excessive pressure, and reduces the structural strength requirements of the conveying device 2.

[0034] However, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, any simple modifications and equivalent structural changes made based on the description and drawings of the present invention should also be included within the patent scope of the present invention and are hereby stated.
