Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas pipeline construction technology, specifically a gas pipeline construction device for building engineering. Background Technology
[0002] Natural gas pipelines are pipelines that transport natural gas, including associated gas from oil fields, from extraction sites or processing plants to urban gas distribution centers or industrial users. Also known as gas transmission pipelines, they are the primary method for transporting large quantities of natural gas overland. Natural gas pipelines account for approximately half of the world's total pipeline length.
[0003] Currently, during the construction of gas pipelines, the inside of the gas pipelines is usually cleaned to ensure the cleanliness and smooth flow of gas, thus ensuring the safety and efficiency of gas transmission. However, most existing gas pipeline cleaning devices require manual insertion of a long pole into the pipeline using brushes mounted on the pole. This method is greatly affected by the length of the pipeline. When the pipeline is too long, the cleaning device may not be able to reach the middle of the pipeline, resulting in blind spots in the cleaning process. Furthermore, the impurities generated during cleaning are not easily discharged from the pipeline, leaving residues. Utility Model Content
[0004] The purpose of this utility model is to provide a gas pipeline construction device for building engineering, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A gas pipeline construction device for building engineering includes a cross plate, a folding plate, and a gear transmission assembly. Folding plates are provided on all four sides of the cross plate, with an angle of 90° between the folding plates and the cross plate. Four lead screws with an angle of 90° are provided on the back of the cross plate. One end of each lead screw is connected via the gear transmission assembly, on which a first motor is mounted. The other end of each lead screw is rotatably connected to a corresponding folding plate. A U-shaped bracket is mounted on the nut of each lead screw, and a traveling wheel is mounted on the other end of the U-shaped bracket. A second motor is mounted on a wheel frame on one side of the traveling wheel. A third motor is mounted in the middle of the cross plate, and a rod sleeve is mounted on the output shaft of the third motor. A brush plate is mounted on the rod sleeve, and brush bristles are evenly distributed on its side. An annular gas pipe is mounted on the front of the cross plate, and several jet pipes are evenly spaced on the annular gas pipe. The annular gas pipe is sealed to the outlet of a high-pressure gas pump mounted on the cross plate.
[0007] As a further embodiment of this utility model: the gear transmission assembly includes a detachable housing, a passive helical gear, and an active helical gear. There are four passive helical gears, which are respectively installed at the ends of four lead screws. The active helical gear meshes with all four passive helical gears. The active helical gear is fixedly connected to the output shaft of a first motor installed on the outer wall of the detachable housing.
[0008] As a further improvement of this utility model, the two lead screws arranged opposite to each other have the same thread direction.
[0009] As a further improvement of this utility model, the rod sleeve is fixedly connected to the output shaft of the third motor by screws.
[0010] As a further improvement of this utility model, the two ends of the U-shaped bracket are movably connected through corresponding folding plates.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, by setting up a cross plate, a folding plate, a gear transmission assembly, a first motor, a lead screw, a U-shaped bracket, a traveling wheel, and a second motor in cooperation, enables the device to move automatically inside the pipeline, which facilitates the cleaning and purging of the pipeline.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 In this embodiment of the present invention, a gas pipeline construction device for building engineering includes a cross plate 1, a folding plate 2, and a gear transmission assembly 3. Folding plates 2 are provided on all four sides of the cross plate 1, with an angle of 90° between the folding plates 2 and the cross plate 1. Four lead screws 5 with an angle of 90° between them are provided on the back of the cross plate 1. One end of each of the four lead screws 5 is connected to the gear transmission assembly 3 via a transmission mechanism. A first motor 4 is mounted on the gear transmission assembly 3. The gear transmission assembly 3 includes a detachable housing 301, a passive helical gear 302, and an active helical gear 303. Four passive helical gears 302 are provided, and the four passive helical gears are connected to the active helical gear 303 via a transmission mechanism. The moving helical gears 302 are respectively installed at the ends of the four lead screws 5. The driving helical gear 303 meshes with the four driven helical gears 302. The driving helical gear 303 is fixedly connected to the output shaft of the first motor 4 installed on the outer wall of the detachable housing 301. The other end of the lead screw 5 is rotatably connected to the corresponding folding plate 2. A U-shaped bracket 6 is installed on the nut of the lead screw 5. The two ends of the U-shaped bracket 6 can move through the corresponding folding plate 2. This design can make the U-shaped bracket 6 more stable during movement. A traveling wheel 7 is installed on the other end of the U-shaped bracket 6. A second motor 8 is installed on the wheel frame on one side of the traveling wheel 7.
[0021] The two lead screws 5, which are set opposite to each other, have the same thread direction. This design allows the two lead screws 5 to drive the opposite traveling wheels 7 to move in opposite directions to accommodate gas pipes of different sizes.
[0022] Please see Figure 1 , Figure 2 and Figure 4A third motor 14 is installed in the middle of the cross plate 1. A rod sleeve 10 is installed on the output shaft of the third motor 14. A brush plate 9 is installed on the rod sleeve 10. Brush bristles 11 are evenly arranged on the side of the brush plate 9. An annular air pipe 12 is installed on the front of the cross plate 1. Several blow pipes 13 are installed at equal intervals on the annular air pipe 12. The annular air pipe 12 is sealed to the air outlet of the high-pressure air pump 15 installed on the cross plate 1.
[0023] The sleeve 10 is fixedly connected to the output shaft of the third motor 14 by screws. The screws make the brush plate 9 detachable, which is convenient for replacing the brush plate 9 and brush bristles 11 after they reach the end of their service life, or for replacing the brush plate 9 and brush bristles 11 with different specifications according to the pipe diameter.
[0024] The working principle of this utility model is as follows: When in use, the person holds the device and suspends it in the gas pipe opening. Then, the first motor 4 is started. The first motor 4 drives the active helical gear 303 to rotate. The active helical gear 303 drives the four lead screws 5 to rotate synchronously through meshing with the other four passive helical gears 302. The lead screws 5 drive the U-shaped bracket 6 to extend outward until the traveling wheel 7 abuts against the inner wall of the pipe. Then, the second motor 8 is started. The second motor 8 drives the traveling wheel 7 to rotate, thereby driving the device to move along the inner wall of the pipe. At the same time, the third motor 14 drives the brush plate 9 to rotate. The brush plate 9 sweeps the inner wall of the pipe with the brush bristles 11. Then, the high-pressure air pump 15 is started to deliver external air through the annular air pipe 12 to each blowpipe 13. The blowpipe 13 blows the air onto the inner wall of the pipe, blowing the brushed-off impurities forward until the ash impurities are blown out from the other end of the pipe.
