Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a pipeline continuous processing device. Background Art

[0002] The traditional pipeline construction process often follows a linear and relatively time-consuming model: First, the construction team must carefully plan and lay the pipeline route, transporting prefabricated pipe materials to the site one by one and laying them out one by one. This process not only requires a high degree of precision to ensure the pipeline's route aligns with the design, but also involves a significant amount of manpower and material resources. Then, in the assembly phase, workers must meticulously align adjacent pipe sections and adjust their positions to ensure tightness and parallelism at the joints. This process tests the workers' professional skills and patience.

[0003] However, traditional assembly is followed by welding. Due to the rigid construction process, it is difficult to form efficient parallel operations between the various processes, resulting in low overall construction efficiency and increased costs. Utility Model Content

[0022] To illustrate the features of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] See also Figure 1An embodiment of the utility model provides a continuous pipeline processing device, including a pipe rack 1 and a conveying device 2. The pipe rack 1 is arranged on the side of the starting point of the conveying device 2. A welding processing unit 3, a flaw detection unit 4 and an anti-corrosion processing device 5 are sequentially arranged on the conveying device 2. The distance between adjacent units is adapted to the length of a single section of pipeline. A traction device 6 is arranged at the end of the conveying device 2 to pull the welded pipes to the trench.

[0025] The conveying device 2 includes 6 pulleys 21 of the same height that support the tube. The pulleys 21 are connected to the motor 22 for driving. Specifically, the motor 22 is provided with a combined transmission shaft to synchronously drive all the pulleys 21. The combined transmission shaft includes a driving shaft 23 and 6 driven shafts 24. The driving shaft 23 is vertically arranged to the driven shaft 24. The driving shaft 23 is provided with a steering device to drive the driven shaft 24. The driven shaft 24 is fixedly connected to the pulley 21, so that one motor drives all the pulleys 21, thereby achieving controllable conveying speed.

[0026] The traction device 6 is an excavator provided with a traction rope for traction of the pipeline, which can realize digging a trench while traction is performed, and the welded and assembled pipeline is pulled into place.

[0027] At the same time, in order to smoothly move the pipeline from the pipe rack 1 to the conveying device 2, a connecting bridge 11 is provided on the pipe rack 1 to be fixedly connected to the conveying device 2, and the pipeline can be rolled from the connecting bridge 11 to the conveying device 2.

[0028] The method of using this embodiment is:

[0029] The transmission device 2 is placed on a leveled surface. The pipe rolls from the pipe rack 1 onto the pulley 21 on the transmission device 2, which then transfers the pipe to the welding processing unit 3. If the pipe is light, a pulley block can be used to manually push the pipe into the welding processing unit 3, eliminating the need for motors and drive shafts. The horizontal placement of the transmission device 2 greatly facilitates pipe assembly and significantly improves assembly efficiency.

[0030] Welding unit 3 consists of an assembly device and automatic welding equipment. Utilizing this unit improves assembly and welding efficiency and quality. The selection of the automatic welding machine and welding materials depends on the pipe diameter, wall thickness, and pipe material. In this example, the pipe is made of 20-gauge steel, so E4303 gas shielded flux-cored wire LQ122 can be used. A Panasonic automatic welding machine is used.

[0031] After welding, the transmission device 2 is used to transport it to the flaw detection unit 4. The detection instrument detects the welding quality, directly records the welding quality data, and performs AUT non-destructive testing at the same time. If there is a problem with the welding quality and rework is required, the transmission device 2 will drag the pipeline back to the welding processing unit 3 for rework. After passing the inspection, the transmission device is used to pull the pipeline into the anti-corrosion patching unit. After the patching construction is completed, the pipeline can be directly lowered into the trench using the traction device 6, which replaces the traditional pipe laying. The choice of anti-corrosion patching method is based on design requirements for anti-corrosion. Similar to assembly line construction, simultaneous welding, testing, patching, and trenching greatly improves the efficiency of pipeline construction.

[0032] Example 2:

[0033] See also Figures 2 to 3 An embodiment of the utility model provides a continuous pipeline processing device, including a pipe rack 1 and a conveying device 2. The pipe rack 1 is arranged on the side of the starting point of the conveying device 2. A welding processing unit 3, a flaw detection unit 4 and an anti-corrosion processing device 5 are sequentially arranged on the conveying device 2. The distance between adjacent units is adapted to the length of a single section of pipeline. A traction device 6 is arranged at the end of the conveying device 2 to pull the welded pipes to the trench.

[0034] The transmission device 2 includes six pulleys 21 of the same height that support the tube. The pulleys 21 are connected to a motor 22 for driving. Specifically, the motor 22 is provided with a combined transmission shaft to synchronously drive all pulleys 21. The combined transmission shaft includes a driving shaft 23 and nine driven shafts 24. The driving shaft 23 is arranged perpendicular to the driven shaft 24. The driving shaft 23 is provided with a steering device to drive the driven shaft 24. The driven shaft 24 is fixedly connected to the pulley 21, so that one motor drives all pulleys 21, thereby achieving controllable transmission speed. In this embodiment, the steering device includes a first bevel gear 231 fixedly provided on the driving shaft 23 and a second bevel gear 241 fixedly provided at the end of the driven shaft 24. The first bevel gear 231 meshes with the second bevel gear 241. The vertical bevel gears cooperate to achieve transmission steering.

[0035] The traction device 6 is an excavator provided with a traction rope for traction of the pipeline, which can realize digging a trench while traction is performed, and the welded and assembled pipeline is pulled into place.

[0036] At the same time, in order to smoothly move the pipeline from the pipe rack 1 to the conveying device 2, a connecting bridge 11 is provided on the pipe rack 1 to be fixedly connected to the conveying device 2, and the pipeline can be rolled from the connecting bridge 11 to the conveying device 2.

[0037] In this embodiment, the welding processing unit 3 is configured as a mobile welding device. If there is a problem with the welding quality and rework is required, it can be directly moved to the return workpiece to avoid the reversal of the conveying device 2 affecting the processing rhythm.

[0038] In addition, this embodiment also includes a conduit support 7 disposed within the trench to adjust the conduit's laying angle. The support 7 is positioned transversely within the trench, with both ends fixedly connected to the trench wall. The support 7 is fitted with a set of rotatable rollers 71, which convert sliding friction on the conduit into rolling friction, thus preventing wear on the conduit surface.

[0039] The method of using this embodiment is:

[0040] The transmission device 2 is placed on a leveled surface. The pipe rolls from the pipe rack 1 onto the pulley 21 on the transmission device 2, which then transfers the pipe to the welding processing unit 3. If the pipe is light, a pulley block can be used to manually push the pipe into the welding processing unit 3, eliminating the need for motors and drive shafts. The horizontal placement of the transmission device 2 greatly facilitates pipe assembly and significantly improves assembly efficiency.

[0041] Welding unit 3 consists of an assembly device and automatic welding equipment. Utilizing this unit improves assembly and welding efficiency and quality. The selection of the automatic welder and welding materials depends on the pipe diameter, wall thickness, and material. In this example, the pipe is made of 20-gauge steel, so E4303 gas shielded flux-cored wire LQ172 can be used. A Megmeet welder is used as the automatic welder.

[0042] After welding, the transmission device 2 is used to transport it to the flaw detection unit 4. The detection instrument detects the welding quality, directly records the welding quality data, and performs PAUT non-destructive testing at the same time. If there is a problem with the welding quality and rework is required, the transmission device 2 will drag the pipeline back to the welding processing unit 3 for rework. After passing the inspection, the transmission device is used to pull the pipeline into the anti-corrosion patching unit. After the patching construction is completed, the pipeline can be directly lowered into the trench using the traction device 6, which replaces the traditional pipe laying. The choice of anti-corrosion patching method is based on design requirements for anti-corrosion. Similar to assembly line construction, simultaneous welding, testing, patching, and trenching greatly improve the efficiency of pipeline construction.
