Description

Technical Field

[0001] The present invention relates to the technical field of pipeline positioning, and in particular to a pipeline positioning device based on a BIM system. Background Art

[0002] In the prior art, the BIM prefabricated pipeline project first simulates the pipeline installation scene and makes drawings by computer, and then assembles the pipeline on site. When the construction workers assemble two pipelines, they need to clamp and position the two pipelines. The construction workers use clamps and bolts to clamp and position the two pipelines. When clamping and positioning, they need to move or support the pipelines, which is very inconvenient to use, resulting in poor clamping and positioning effects. In addition, the weight of the pipe fittings is large, which poses a safety hazard when positioning the pipelines.

[0003] After searching, the Chinese patent application number 202323355557.0 discloses a pipeline positioning device for BIM-based prefabricated pipeline engineering, including a fixed frame, etc.; a sliding frame is fixedly installed on the fixed frame, and one side of the fixed frame and the sliding frame are fixedly connected to a guide frame, and two clamping frames are slidably connected to the two guide frames.

[0004] The pipeline positioning device for prefabricated pipeline projects based on BIM in the above-mentioned patent has the following shortcomings: during the positioning of the pipeline, the position of the pipeline in the horizontal, lateral and longitudinal directions cannot be quickly adjusted, and the position of the clamping frame needs to be manually adjusted during the adjustment process, which makes the efficiency of pipeline positioning low.

[0010] Preferably: the elastic clamping member includes a spring and a T-shaped rod, the T-shaped rod is movably connected to the inner wall of the through hole opened on the surface of the side plate, and the two ends of the spring are respectively clamped on the outer wall of one side of the side plate and the inner wall of one side of the T-shaped rod, and a clamping plate is fixed at one end of the T-shaped rod, and a accommodating plate is welded on the side wall of the clamping plate, and a conveying roller is movably connected between the two accommodating plates.

[0011] Preferably: a servo motor 1 is fixed to an outer wall of one side of one of the accommodating plates, and an output end of the servo motor 1 is connected to one end of a conveying roller through a coupling.

[0012] Preferably: a wheel speed sensor is fixed to an outer wall of one side of another of the accommodating plates, and the wheel speed sensor is electrically connected to the conveying roller.

[0013] Preferably, the walking assembly comprises a pad, a vertical plate and a moving wheel, the pad is fixed to the output end of the hydraulic cylinder by a pin, the vertical plate is welded to the outer wall of the bottom of the pad, and the moving wheel is movably connected between the two vertical plates.

[0022] 5. Pipeline 1 can be fixed by providing a mounting plate.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Embodiment 1:

[0033] A pipeline positioning device based on BIM system, such as Figures 1 to 6 As shown, it includes a moving frame 1 for positioning between a pipe 27 and a pipe fitting, a through hole opened on the moving frame 1 is slidably connected with a support assembly, and the outer walls on both sides of the moving frame 1 are fixed with a lifting part, the lifting part includes a hydraulic cylinder 22 and a square plate 23, and the square plate 23 is welded to the side wall of the moving frame 1, and the hydraulic cylinder 22 is fixed to the outer wall of the top of the square plate 23 by bolts, and a walking assembly is fixed to the output end of the hydraulic cylinder 22, and the outer walls on the other two sides of the moving frame 1 are fixed with an L-shaped plate 16 by bolts, and the through hole opened on the surface of the L-shaped plate 16 is slidably connected with a sliding plate 8, and one end of the sliding plate 8 is welded with a side plate 17, and the surface of the side plate 17 is slidably connected with an elastic clamp, and one end of the side plate 17 is welded with a connecting frame 21, and one end of the walking assembly is welded with a U-shaped plate 19, and a connecting rod 20 is rotatably connected between the U-shaped plate 19 and the connecting frame 21;

[0034] First, based on BIM, the computer is used to simulate the pipeline installation scenario and make drawings. When it is necessary to position and install the pipe 27 and the pipe fittings on site by welding, in order to ensure that the pipe 27 and the pipe fittings can be accurately docked and positioned and to ensure the stability during welding, a support assembly is provided to support the entire device before welding. During welding, the hydraulic cylinder 22 is controlled so that its output end drives the walking assembly downward during the gradual extension process. When the walking assembly moves down to contact the ground, the output end of the hydraulic cylinder 22 continues to move, causing the support assembly to gradually leave the ground and be suspended. During the movement of the walking assembly, the connecting rod 20 is used to move the supporting assembly downward. The vertical movement of the walking assembly is converted into the lateral movement of the sliding plate 8 along the L-shaped plate 16, so that the pipe 27 to be positioned is clamped and fixed during the relative movement of the two sets of elastic clamps on the same side of the moving frame 1. Since the elastic clamps are elastic, the sliding plate 8 can continue to slide along the L-shaped plate 16 after the pipe 27 is clamped, thereby adjusting the inclination angle of the connecting rod 20. When the inclination angle of the connecting rod 20 increases, the height of the pipe 27 will also change accordingly. Therefore, after the pipe 27 is clamped and fixed, its height is adjusted so that the height of the pipe 27 is flush with the height of the pipe fitting, which is convenient for welding between the pipe 27 and the pipe fitting.

[0035] The support assembly includes a sliding rod 2 and a moving plate 3, the sliding rod 2 is slidably connected to the inner wall of the through hole opened on the side wall of the moving frame 1, and the two moving plates 3 are respectively fixed to the two ends of the sliding rod 2 by bolts, and a bracket 11 is welded at the bottom of the moving plate 3, and the inner walls on both sides of the bracket 11 are rotatably connected with rollers 10, a driving motor 12 is fixed to the inner wall of one side of the moving frame 1 by bolts, and the output end of the driving motor 12 is connected to a threaded rod 4 through a coupling, and the threaded rod 4 and one of the moving plates 3 are threadedly connected;

[0036] When the walking assembly props up the supporting assembly, the driving motor 12 is used to drive the threaded rod 4 to rotate, so that the moving plate 3 moves laterally along the moving frame 1 under the guidance of the sliding rod 2, thereby adjusting the lateral position of the roller 10.

[0037] The elastic clamping member includes a spring 27 and a T-shaped rod 28, the T-shaped rod 28 is slidably connected to the inner wall of the through hole opened on the surface of the side plate 17, and the two ends of the spring 27 are respectively clamped on the outer wall of one side of the side plate 17 and the inner wall of one side of the T-shaped rod 28, and one end of the T-shaped rod 28 is fixed with a clamping plate 18 by screws, and a receiving plate 31 is welded to the side wall of the clamping plate 18, and a conveying roller 30 is rotatably connected between the two receiving plates 31, and a servo motor 1 32 is fixed to the outer wall of one side of one of the receiving plates 31 by screws, and the output end of the servo motor 1 32 is connected to one end of the conveying roller 30 through a coupling, and a wheel speed sensor 29 is fixed to the outer wall of one side of the other receiving plate 31 by screws, and the wheel speed sensor 29 and the conveying roller 30 are electrically connected;

[0038] In the initial stage, the distance between the two clamps 18 on the same side of the moving frame 1 is greater than the outer diameter of the pipe 7. By setting one side of the clamp 18 as a V-shaped structure, it is convenient to clamp and fix the pipes 7 with different outer diameters. When the two sets of clamps 18 are in relative motion, the pipe 7 is clamped and fixed by the conveying roller 30. When the conveying roller 30 and the outer wall of the pipe 7 are in contact with each other, the U-shaped plate 19 can continue to move under the drive of the hydraulic cylinder 22 by providing a spring 27, so that the height of the pipe 7 after clamping can be adjusted. When it is necessary to adjust the lateral position of the pipe 7, the servo motor 32 is used to drive the conveying roller 30 to rotate, so that the pipe 7 is moved laterally by the rotating conveying roller 30 under the action of friction force. The conveying distance of the conveying roller 30 is monitored in real time by the wheel speed sensor 29, and the lateral conveying distance of the pipe 7 can be set.

[0039] The walking assembly includes a pad 9, a vertical plate 24 and a moving wheel 26, wherein the pad 9 is fixed to the output end of the hydraulic cylinder 22 by a pin, and the vertical plate 24 is welded to the outer wall of the bottom of the pad 9, and the moving wheel 26 is rotatably connected between the two vertical plates 24, and a servo motor 25 is fixed to the outer wall of one side of the vertical plate 24 by screws, and the output end of the servo motor 25 is connected to one end of one of the moving wheels 26 through a coupling;

[0040] When the welding between the pipe 27 and the pipe fitting is completed, the servo motor 25 is used to drive the moving wheel 26 to rotate so that the moving wheel 26 moves along the ground. Since the conveying roller 30 can roll along the outer wall of the circumference of the pipe 27, the entire device can move along the pipe 27, thereby detaching from the pipe 27, making it easier to weld multiple groups of pipes 27, thereby improving the construction efficiency.

[0041] The moving wheel 26 can realize the lateral movement of the entire device. When the lateral position of the entire device needs to be adjusted, when the support assembly is in a suspended state, the drive motor 12 is used to drive the threaded rod 4 to rotate, so that the two groups of brackets 11 move laterally under the connection action of the sliding rod 2. When the output end of the hydraulic cylinder 22 is reset, the support assembly is moved again to fit between the ground, and the support assembly will move a certain distance relative to the initial position in the lateral direction. At this time, when the drive motor 12 continues to drive the threaded rod 4 to rotate, since the walking assembly is suspended, the moving frame 1 will slide along the sliding rod 2 under the guidance of the sliding rod 2, and the walking assembly will also move a certain distance in the lateral direction. In this way, the entire device can move laterally in a manner similar to creeping.

[0042] The top outer wall of the mobile frame 1 is fixed with a base 13 by bolts, and an infrared rangefinder 14 is fixed with screws to one side outer wall of the base 13, and a receiving plate 15 used in conjunction with the infrared rangefinder 14 is fixed with screws to the top outer wall of one of the mobile plates 3;

[0043] By providing the infrared rangefinder 14 and the receiving plate 15 , the distance between the moving plate 3 and the moving frame 1 can be measured, that is, it is ensured that the supporting assembly moves a set distance along the moving frame 1 .

[0044] The pipe fitting includes a pipe 5 and a mounting plate 6, and the pipe 5 is fixed to the inner wall of a through hole opened on the surface of the pipe 5 by embedding;

[0045] By providing a mounting plate 6, pipe 1 5 can be fixed. When pipe 2 7 and pipe 1 5 need to be welded, the above method is used to achieve accurate docking between pipe 2 7 and pipe 1 5, thereby ensuring the stability and accuracy of pipe 1 5 and pipe 2 7 during welding.

[0046] When this embodiment is used, firstly, the pipeline installation scene is simulated by computer based on BIM and a drawing is made. When it is necessary to position and install the pipe 27 and the pipe fittings on site by welding, first, the pipe 27 is placed between two adjacent clamps 18, and then the hydraulic cylinder 22 is used to drive the walking assembly to move downward. When the walking assembly moves to the ground, the distance between the two adjacent clamps 18 is shortened, so that the pipe 27 is clamped and fixed. After the pipe 27 is clamped and fixed, the output end of the hydraulic cylinder 22 continues to move, so that the spring 27 is gradually stretched, and the height of the pipe 27 is gradually increased. When the pipe 27 moves to a position directly opposite to the pipe 1 5, the output end of the hydraulic cylinder 22 stops moving. At this time, the servo motor 1 32 is used to drive the conveying roller 30 to rotate so that the conveying roller 30 presses the pipe 27 along It is transported horizontally. When one end of pipe 27 moves to be aligned with one end of pipe 15, the joint between pipe 15 and pipe 27 is welded. After welding is completed, the servo motor 25 is used to drive the moving wheel 26 to rotate so that the whole device moves along pipe 27 and detaches from pipe 27. When it is necessary to weld the next pipe 27 and pipe 15, the drive motor 12 is first used to drive the threaded rod 4 to rotate so that the support assembly moves a certain distance laterally. Then the hydraulic cylinder 22 is used to drive the walking assembly to reset. Then the drive motor 12 is continued to drive the threaded rod 4 to rotate so that the moving frame 1 slides a certain distance along the sliding rod 2, thereby causing the walking assembly to move a certain distance laterally. The whole device moves forward in a manner similar to creeping to weld multiple pipes 27 and the corresponding pipes 15.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
