Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of trenching and pipe burying construction, and particularly relates to a device for trenching and pipe burying construction and a trenching and pipe burying construction method. BACKGROUND

[0002] The steel pipe trenching and pipe burying technology is a traditional construction method widely used in the fields of municipal engineering, oil and gas transportation, water conservancy system, etc. Its core process includes ground trenching, pipe laying, backfilling and compaction, etc. Among them, pipe connection is a key link in the construction of steel pipe trenching and pipe burying, which directly affects the sealing performance, structural strength and long-term operation safety of the pipe. The conventional construction method for pipe laying is as follows: ① cushion construction; ② pipe hoisting and positioning; ③ pipe alignment; ④ pipe welding. According to article 5.3.16 of (GB 50268-2008) "Water Supply and Drainage Pipe Engineering Construction and Acceptance Specification": "When the pipe diameter is greater than 800 mm, double-sided welding shall be used." For large-diameter steel pipes, internal welding is convenient for construction, but external pipe bottom welding is difficult, which needs local over-excavation and support support at the welding position, which is more dangerous and difficult to operate, and it is difficult to guarantee the welding quality.

[0011] In one embodiment, the welding mechanism is arranged outside one side of the two guide rails in the length direction of the guide rail;

[0012] Further comprising a detection mechanism, the detection mechanism is arranged outside the other side of the two guide rails in the length direction of the guide rail and is arranged opposite to the welding mechanism, and is used for detecting the weld.

[0015] In one embodiment, the guide rail mechanism further comprises a connecting rod, the connecting rod is used for connecting the two guide rails, and the connecting rod is a plurality of connecting rods, the plurality of connecting rods are arranged at intervals along the length direction of the guide rail.

[0016] In one embodiment, the connecting rod is detachably connected with the guide rail; and / or

[0017] The connecting rod is a telescopic rod, so as to adapt to the pipeline with different diameters by adjusting the spacing of the two guide rails.

[0018] In one embodiment, further comprising a pad, the pad is arranged between the pipeline mounting area and the pipeline, so as to replace the pipeline supported by the support transmission mechanism; and / or

[0019] The guide rail is detachably connected with the pipeline mounting area; and / or

[0020] The support transmission member is detachably connected with the guide rail; and / or

[0021] The guide rail mechanism also includes connecting rods for connecting two guide rails. There are multiple connecting rods, which are arranged at intervals along the length of the guide rails. Each connecting rod includes a middle section and two end sections. The two end sections are retractably connected to the two ends of the two middle sections, and the end of each end section away from the middle section is detachably connected to the guide rail.

[0022] The present invention also provides a method for trenching and embedding pipes, comprising the following steps:

[0023] Based on the installation locations of multiple pipes in the pipe installation area, multiple installation stations are determined, and two adjacent installation stations are designated as the hoisting and unloading station and the material receiving station, respectively.

[0024] The trenching and pipe-laying construction device as described in any one of claims 1-8 is installed in the pipe installation area, wherein the guide rail extends along the arrangement direction of multiple installation positions, the welding mechanism is correspondingly set at the boundary position between the hoisting and unloading position and the material-bearing position, and at least one of the support transmission groups is correspondingly set to one of the installation positions; and

[0025] When both the hoisting and unloading station and the repositioning and receiving station have pipes to be welded, the support transmission group controls the pipes on it to rotate at least one revolution. At the same time, the welding mechanism welds the pipes to be welded on the hoisting and unloading station and the repositioning and receiving station. After the welding is completed, the support transmission group controls the pipes on it to move along the length of the guide rail so that the pipes on the hoisting and unloading station move to the repositioning and receiving station. Then, the pipes to be welded are hoisted at the hoisting and unloading station. The above process is repeated until multiple pipes are welded.

[0026] In one embodiment, before the first welding, a pipe to be welded is first hoisted at the hoisting and unloading station, then the support transmission assembly controls the pipe to be welded to move along the length of the guide rail to the buffer receiving station, and then another pipe to be welded is hoisted at the hoisting and unloading station; and / or

[0027] After the final welding is completed, do not move the pipe from the hoisting and unloading station to the buffer receiving station; and / or

[0028] After welding is completed, and both the hoisting and unloading station and the receptacle station have welded pipes, the support transmission assembly controls the pipes on it to rotate at least one revolution to check if the weld is qualified. After the weld is qualified, the support transmission assembly controls the pipes on it to move along the length of the guide rail, so that the pipes at the hoisting and unloading station move to the receptacle station; and / or

[0029] After all the pipes have been welded, the process also includes the step of removing the trenching and pipe-burying construction device, and before removing the support transmission mechanism, a pad is placed between the pipe installation area and the pipe.

[0030] When using the above-mentioned trenching and pipe-laying construction device for trenching and pipe-laying construction, multiple installation positions can be determined first based on the installation locations of multiple pipes in the pipe installation area. Two adjacent installation positions can be designated as the hoisting and unloading position and the repositioning and material-bearing position, respectively. Typically, the foremost or last installation position can be designated as the hoisting and unloading position. Then, the trenching and pipe-laying construction device can be installed in the pipe installation area. The guide rails extend along the arrangement direction of the multiple installation positions. The welding mechanism is set at the boundary position between the hoisting and unloading position and the repositioning and material-bearing position. At least one support transmission group is set at each installation position, so that at least one support transmission group corresponds to one pipe to support it. Next, when both the hoisting and unloading station and the repositioning and receiving station have pipes to be welded, the support transmission group controls the pipes on them to rotate at least one revolution. Simultaneously, the welding mechanism welds the pipes to be welded at both stations. After welding, the support transmission group controls the pipes on them to move along the length of the guide rail, so that the pipe at the hoisting and unloading station moves to the repositioning and receiving station. Then, the pipe to be welded is hoisted at the hoisting and unloading station, and the above process is repeated until multiple pipes are welded. Specifically, before the first weld, one pipe to be welded is hoisted at the hoisting and unloading station, and then the support transmission group controls this pipe to move along the length of the guide rail to the repositioning and receiving station. Then, another pipe to be welded is hoisted at the hoisting and unloading station. After the final weld, the pipe at the hoisting and unloading station is not moved to the repositioning and receiving station.

[0031] When using the aforementioned trenching and pipe-laying construction device, if both the hoisting and unloading position and the repositioning and receiving position have pipes to be welded, the support and transmission assembly controls the pipes on them to rotate at least one revolution. Simultaneously, the welding mechanism welds the pipes to be welded at both positions, facilitating welding at the outer pipe bottom. Furthermore, when using this device, a single pipe can be hoisted at a fixed point, and both single pipes and at least two pipes welded together can be transported on guide rails (the support and transmission assembly controls the pipes to move along the length of the guide rails). This reduces the space requirements for the hoisting equipment (truck crane) and makes it less susceptible to environmental influences such as structures, making it easier to implement. In addition, the welding mechanism allows for fixed-point welding, making welding easier to operate. This trenching and pipe-laying construction device significantly mechanizes the process, thereby accelerating construction speed and better ensuring construction quality. Attached Figure Description

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0052] like Figures 1-3 As shown, this is an embodiment of the trenching and pipe-laying construction device 10 of the present invention. In this embodiment, the trenching and pipe-laying construction device 10 is applied in a foundation pit, the bottom of which has a pipe installation area 20, and the pipe 30 to be buried is a steel pipe.

[0053] The trenching and pipe-laying construction device 10 includes a guide rail mechanism 200, a support transmission mechanism 300, and a welding mechanism 400. The guide rail mechanism 200 includes two guide rails 210, which are spaced apart and positioned relative to each other in the pipe installation area 20. The support transmission mechanism 300 includes multiple support transmission assemblies 300a. These multiple support transmission assemblies 300a are arranged at intervals along the length of the guide rails 210. Each support transmission assembly 300a includes two support transmission members 310 respectively mounted on the two guide rails 210. At least one support transmission assembly 300a corresponds to a pipe 30 to support the pipe 30. The support transmission assembly 300a can control the rotation of the pipe 30 on it and can control the movement of the pipe 30 along the length of the guide rail 210. The welding mechanism 400 is used to weld two pipes 30 to be welded.

[0054] When using the above-mentioned trenching and pipe-laying construction device 10 for trenching and pipe-laying construction, multiple installation positions can be determined first based on the installation locations of multiple pipes 30 in the pipe installation area 20. Two adjacent installation positions are designated as the hoisting and unloading position and the repositioning and material-bearing position, respectively. Usually, the foremost or the last installation position can be designated as the hoisting and unloading position. Then, the above-mentioned trenching and pipe-laying construction device 10 can be installed in the pipe installation area 20. The guide rail 210 extends along the arrangement direction of the multiple installation positions. The welding mechanism 400 is set at the boundary position between the hoisting and unloading position and the repositioning and material-bearing position. At least one support transmission group 300a is set at one installation position, so that at least one support transmission group 300a corresponds to one pipe 30 to support the pipe 30. Next, when both the hoisting and unloading station and the repositioning and receiving station have pipes 30 to be welded, the support transmission group 300a controls the pipes 30 on it to rotate at least one revolution. Simultaneously, the welding mechanism 400 welds the pipes 30 to be welded at both the hoisting and unloading station and the repositioning and receiving station. After welding, the support transmission group 300a controls the pipes 30 on it to move along the length of the guide rail 210, so that the pipes 30 at the hoisting and unloading station move to the repositioning and receiving station. Then, the pipes 30 to be welded are hoisted at the hoisting and unloading station, and the above process is repeated until multiple pipes 30 are welded. Specifically, before the first welding, one pipe 30 to be welded is hoisted at the hoisting and unloading station, and then the support transmission group 300a controls this pipe 30 to move along the length of the guide rail 210 to the repositioning and receiving station. Then, another pipe 30 to be welded is hoisted at the hoisting and unloading station. After the final welding is completed, the pipes 30 at the hoisting and unloading station are not moved to the repositioning and receiving station.

[0055] When using the above-mentioned trenching and pipe-laying construction device 10 for trenching and pipe-laying construction, if there are pipes 30 to be welded at both the hoisting and unloading position and the receptacle and receiving position, the support transmission group 300a controls the pipes 30 on it to rotate at least one revolution. At the same time, the welding mechanism 400 welds the pipes 30 to be welded at the hoisting and unloading position and the receptacle and receiving position, which is very convenient for welding at the bottom of the external pipe. Moreover, when using the above-mentioned trenching and pipe-laying construction device 10 for trenching and pipe-laying construction, a single pipe 30 can be hoisted at a fixed point, and both a single pipe 30 and at least two pipes 30 welded together can be transported on the guide rail 210 (the support transmission group 300a controls the pipes 30 on it to move along the length of the guide rail 210). The requirements for the working space of the hoisting equipment (truck crane) are low, and the hoisting equipment (truck crane) is not easily affected by the surrounding environment such as structures, making it easier to implement. In addition, the above-mentioned welding mechanism 400 can weld at fixed points, making welding easier to operate. The above-mentioned trenching and pipe laying construction device 10 can make trenching and pipe laying construction more mechanized, thereby speeding up the construction speed and better ensuring the construction quality.

[0056] In this embodiment, asFigure 4 and Figure 5 As shown, the support transmission component 310 includes a mounting frame 312, Mecanum wheels 314, and motors. The mounting frame 312 includes a frame body 312a and two mounting rods 312b. The two mounting rods 312b are spaced apart along the length of the guide rail 210. There are four Mecanum wheels 314, each located at the end of one of the two mounting rods 312b. There are four motors, with two motors paired with each of the four Mecanum wheels 314. The four Mecanum wheels 314 support the pipe 30. Driven by the four motors, the four Mecanum wheels 314 control the rotation of the pipe 30 and its movement along the length of the guide rail 210. This not only facilitates the control of the rotation of the pipe 30 on the support transmission assembly 300a and its movement along the length of the guide rail 210, but also allows for control of the movement of the four Mecanum wheels 314 via a remote control connected to the motors, making operation very convenient. It is understood that in other embodiments, other solutions can be adopted to enable the support transmission assembly 300a to control the rotation of the pipe 30 thereon and to control the movement of the pipe 30 along the length direction of the guide rail 210.

[0057] It should be noted that the working principle of the aforementioned support transmission component 310 is existing technology, and will only be briefly introduced here without detailed explanation. For example... Figure 6 and Figure 7 As shown, each diagonal line on the Mecanum wheel 314 is a small wheel. By controlling the tilting direction of the small wheels of the four Mecanum wheels 314 (the tilting direction of the small wheels of the Mecanum wheels 314 on the same side is opposite, and the tilting direction of the small wheels of the Mecanum wheels 314 on opposite sides is the same) and by controlling the movement direction of the small wheels of each Mecanum wheel 314 by the motor, the direction of the resultant force of the support transmission component 310 can be controlled. Figure 6 The resultant force of the support transmission component 310 shown is to the right, which can control the rotation of the pipe 30. Figure 7 The resultant force of the support transmission component 310 shown is forward, which can control the movement of the pipe 30 along the length of the guide rail 210.

[0058] In this embodiment, the mounting rod 312b is rotatably connected to the frame 312a, so that the Mecanum wheel 314 can support pipes 30 of different diameters by adjusting the inclination of the mounting rod 312b. Thus, the above-mentioned trenching and pipe-laying construction device 10 can have a wider range of applications.

[0059] In this embodiment, the frame 312a includes a base 3122, uprights 3124, and reinforcing rods 3126. There are two uprights 3124. The two uprights 3124 are mounted on the base 3122 and spaced apart along the length of the guide rail 210. The reinforcing rods 3126 connect the two uprights 3124. Two mounting rods 312b are respectively mounted on the two uprights 3124. In this embodiment, the mounting rods 312b are rotatably connected to the uprights 3124 via a connecting shaft 3128.

[0060] In this embodiment, as Figures 1-3 As shown, along the length of the guide rails 210, the welding mechanism 400 is mounted on one side of the two guide rails 210. This facilitates the welding of the pipe 30 by the welding mechanism 400. It is understood that in other embodiments, the welding mechanism 400 may also be suspended and fixed above the two guide rails 210.

[0061] In this embodiment, the trenching and pipe-laying construction device 10 also includes a detection mechanism 500. Along the length of the guide rails 210, the detection mechanism 500 is installed on the other side of the two guide rails 210 and directly opposite the welding mechanism 400 for detecting weld seams. This facilitates the detection mechanism 500 in detecting whether the weld seams are qualified, and also allows the welding mechanism 400 to perform on-site repair welding if the weld seams are unqualified. Furthermore, the detection mechanism 500 can be fixed at a fixed point for detection. It is understood that in other embodiments, the detection mechanism 500 can also be suspended and fixed above the two guide rails 210.

[0062] After welding is completed, and both the hoisting and unloading station and the repositioning and receiving station have the welded pipe 30, the support transmission group 300a controls the pipe 30 to rotate at least one revolution to check if the weld is qualified. After the weld is qualified, the support transmission group 300a controls the pipe 30 to move along the length of the guide rail 210, so that the pipe 30 at the hoisting and unloading station moves to the repositioning and receiving station. If the weld is unqualified, the welding mechanism 400 can perform repair welding first, then check, and repeat the above process until the weld is qualified. During the repair welding process, the support transmission group 300a controls the pipe 30 to rotate so that the position to be repaired corresponds to the welding mechanism 400.

[0063] In this embodiment, the detection head of the detection mechanism 500 includes a camera and an ultrasonic sensor. The camera can obtain the appearance information of the weld for appearance inspection, while the ultrasonic sensor can obtain the internal information of the weld for internal inspection. The cooperation between the camera and the ultrasonic sensor can make the detection results more accurate.

[0064] In this embodiment, the welding mechanism 400 is a welding robot. The welding head of the welding mechanism 400 can move in a first direction, a second direction, and a third direction. The inspection mechanism 500 is an inspection robot, and the inspection head of the inspection mechanism 500 can move in a first direction, a second direction, and a third direction. The first direction is the length direction of the guide rail 210, the second direction is the arrangement direction of the two guide rails 210, and the third direction is the height direction. This facilitates precise control of the welding head aligning with the bevel position of the pipe 30 and precise control of the inspection head aligning with the weld.

[0065] In this embodiment, as Figure 1 , Figure 8 and Figure 9 As shown, the guide rail mechanism 200 also includes connecting rods 220. Connecting rods 220 are used to connect two guide rails 210. Multiple connecting rods 220 are arranged at intervals along the length of the guide rails 210. Connecting two guide rails 210 with connecting rods 220 ensures that the guide rails 210 do not shift under stress. It is understood that in other embodiments, when the guide rails 210 can be firmly fixed to the pipe installation area 20, the connecting rods 220 can be omitted.

[0066] In this embodiment, the connecting rod 220 is a telescopic rod, which can be used to accommodate pipes 30 of different diameters by adjusting the distance between the two guide rails 210. Thus, the above-mentioned trenching and pipe-laying construction device 10 has a wider range of applications.

[0067] In this embodiment, the connecting rod 220 is detachably connected to the guide rail 210. This facilitates disassembly and assembly, and allows for the secondary use of the connecting rod 220.

[0068] In this embodiment, the connecting rod 220 includes a middle section 222 and two end sections 224. The two end sections 224 are retractably connected to both ends of the two middle sections 222. The end of each end section 224 away from the middle section 222 is detachably connected to the guide rail 210. This facilitates both extension and retraction, as well as assembly and disassembly. Specifically, in this embodiment, the middle section 222 can be inserted into the hollow end sections 224. Both the outer walls of the middle section 222 and the outer walls of the end sections have external threads. The middle section 222 and the end sections 224 are connected by a fastener 226 with internal threads. When adjusting the length of the connecting rod 220, the relative position of the fastener 226 and the middle section 222 can be adjusted first, so that the middle section 222 protrudes appropriately from the fastener 226. Then, the middle section 222 is inserted into the hollow end sections 224, and the fastener 226 is threadedly connected to the end section 224. Specifically, in this embodiment, the end section 224 is screwed to the guide rail 210.

[0069] In this embodiment, the support transmission component 310 is detachably connected to the guide rail 210. This facilitates disassembly and assembly, and allows for the reuse of the support transmission component 310. Specifically, in this embodiment, the mounting bracket 312 is detachably connected to the guide rail 210. More specifically, in this embodiment, the mounting bracket 312 is connected to the guide rail 210 with screws.

[0070] In this embodiment, the guide rail 210 is detachably connected to the pipe installation area 20. This facilitates disassembly and assembly, and allows for the secondary use of the guide rail 210. Specifically, in this embodiment, the pipe installation area 20 has embedded parts, and the guide rail 210 is detachably connected to the embedded parts.

[0071] In this embodiment, as Figure 10 As shown, the trenching and pipe-laying construction device 10 also includes a pad 600. The pad 600 is used to be placed between the pipe installation area 20 and the pipe 30 to replace the support transmission assembly 300a in supporting the pipe 30. After all the pipes 30 have been welded, the trenching and pipe-laying construction device 10 can be removed. Before removing the support transmission mechanism 300, the pad 600 is placed between the pipe installation area 20 and the pipe 30 to replace the support transmission mechanism 300 in supporting the pipe 30. Specifically, during disassembly, the welding robot and the inspection robot can be disassembled first, then the pad 600 can be placed on the side of the pipe 30, and the support transmission mechanism 300 and the guide rail mechanism 200 can be removed.

[0072] like Figure 11 As shown, the present invention also provides a method for trenching and embedding pipes. This method includes the following steps:

[0073] Step S710: Determine multiple installation stations based on the installation positions of multiple pipes in the pipe installation area, and designate two adjacent installation stations as the hoisting and unloading station and the material receiving station, respectively.

[0074] Step S720: Install the above-mentioned trenching and pipe-laying construction device in the pipe installation area, wherein the guide rail extends along the arrangement direction of multiple installation positions, the welding mechanism is correspondingly set at the boundary position between the hoisting and unloading position and the material-bearing position, and at least one of the support transmission groups is correspondingly set to one of the installation positions; and

[0075] In step S730, when there are pipes to be welded at both the hoisting and unloading station and the repositioning and receiving station, the support transmission group controls the pipes on it to rotate at least one revolution. At the same time, the welding mechanism welds the pipes to be welded at the hoisting and unloading station and the repositioning and receiving station. After welding is completed, the support transmission group controls the pipes on it to move along the length of the guide rail so that the pipes at the hoisting and unloading station move to the repositioning and receiving station. Then, the pipes to be welded are hoisted at the hoisting and unloading station. The above process is repeated until multiple pipes are welded.

[0076] In this embodiment, before the first welding, a pipe to be welded is first hoisted at the hoisting and unloading station. Then, the support transmission group controls the pipe to be welded to move along the length of the guide rail to the avoidance and material receiving station. Then, another pipe to be welded is hoisted at the hoisting and unloading station.

[0077] In this embodiment, after the final welding is completed, the pipe at the hoisting and unloading station is not moved to the material receiving station.

[0078] In this embodiment, after welding is completed, and both the hoisting and unloading station and the relocation and receiving station have welded pipes, the support transmission group controls the pipes on it to rotate at least one revolution to check whether the weld is qualified. After the weld is qualified, the support transmission group controls the pipes on it to move along the length of the guide rail so that the pipes at the hoisting and unloading station move to the relocation and receiving station.

[0079] In this embodiment, after all the pipes have been welded, the step of dismantling the trenching and pipe-burying construction device is also included, and before dismantling the support transmission mechanism, a pad is placed between the pipe installation area and the pipe.

[0080] The above-mentioned trenching and pipe laying construction method mainly includes the following steps:

[0089] When applying the aforementioned trenching and pipe-laying construction device to trenching and pipe-laying projects, a region with favorable environmental conditions is selected as the material preparation area. The steel pipe (pipeline) is hoisted into the pit in this area and placed on the support and transmission mechanism. The support and transmission mechanism drives the pipe to rotate, while a welding robot performs welding at fixed points, and an inspection robot performs visual and ultrasonic inspections at fixed points. After welding and inspection are completed, the support and transmission mechanism moves the pipe along the length of the guide rail, realizing pipe transportation, and the next pipe section is placed, thus completing the cycle. This equipment makes steel pipe trenching and pipe-laying construction more mechanized, thereby accelerating the construction speed and better ensuring construction quality.
