[0002] High-pressure pipes are pipes capable of withstanding pressure and used to transport liquids. They come in many types, including steel pipes, copper pipes, stainless steel pipes, and others. High-quality carbon structural steel and alloy structural steel high-pressure pipes are mainly used to manufacture steam boiler pipes for high-pressure and above applications.

[0003] In existing technologies, Ø108 high-pressure pipes are frequently encountered in coal mining operations for gas extraction and drainage. However, due to the large diameter of the high-pressure pipes and the regular circular shape of their two ends, the joints are prone to rusting and subsequent damage and deformation after prolonged use. This makes it difficult to connect the pipes, causing significant inconvenience to the work. Furthermore, traditional methods often involve manual connection, which is time-consuming, labor-intensive, and difficult to align, resulting in poor connection results. Utility Model Content

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.

[0021] Please see Figures 1-5 This utility model discloses a high-pressure pipe quick-closing device, including a rectangular frame 1. A reinforcing plate 2 is fixedly installed on the front and rear inner walls of the rectangular frame 1 near the middle. A driving mechanism 3 is provided between the left and right sides of the reinforcing plate 2 and the left and right inner walls of the rectangular frame 1. A guide mechanism 4 is fixedly installed between the front and rear sides of the driving mechanism 3 and the rectangular frame 1 and the reinforcing plate 2. A movable plate 5 is fixedly installed between the upper surfaces of the guide mechanism 4. A rectangular opening 6 is opened on the upper surface of the movable plate 5 near the left and right. A clamping mechanism 7 is fixedly installed between the front and rear inner walls of the rectangular opening 6.

[0022] Specifically, the drive mechanism 3 includes a reducer 301, a transmission rod 302, a first bearing assembly 303, a first handle 304, a first ball screw 305, a second bearing assembly 306, and a first ball nut 307. The reducer 301 is fixedly installed on the inner wall of the rectangular frame 1 away from the reinforcing plate 2. The transmission rod 302 is fixedly installed on the input shaft of the reducer 301. The transmission rod 302 is installed in the front side wall of the rectangular frame 1 through the first bearing assembly 303. The first handle 304 is fixedly installed on the front side of the transmission rod 302. The first ball screw 305 is fixedly installed on the output shaft of the reducer 301. The first ball screw 305 is connected to the side of the reinforcing plate 2 through the second bearing assembly 306.

[0023] In this embodiment, the first handle 304 drives the transmission rod 302 to rotate in the first bearing assembly 303, which in turn drives the input shaft of the reducer 301 to rotate. The output shaft of the reducer 301 drives the first ball screw 305 to rotate. The rotation of the first ball screw 305 causes the first ball nut 307 to move left and right, which in turn drives the guide mechanism 4 to move left and right.

[0024] Specifically, the guiding mechanism 4 includes a slider 401 and a guide rail 402. The slider 401 is fixedly installed on the side of the first ball nut 307. The guide rail 402 is movably inserted into the slider 401. The guide rail 402 is fixedly installed between the inner wall of the rectangular frame 1 and the side of the reinforcing plate 2.

[0025] In this embodiment, the slider 401 moves left and right on the guide rail 402 along with the first ball nut 307, causing the slider 401 to drive the moving plate 5 to move left and right, and the slider 401 moves left and right along the guide rail 402 stably.

[0026] Specifically, the slider 401 is movably fitted against the inner wall of the rectangular frame 1 on its side facing the inner wall of the rectangular frame 1.

[0027] In this embodiment, the slider 401 moves along the inner wall of the rectangular frame 1, making the left and right movement of the slider 401 more stable, and the slider 401 supports the side wall of the rectangular frame 1, making it stronger.

[0028] Specifically, the lower surface of the movable plate 5 is movably attached to the upper surface of the rectangular frame 1, and the movable plate 5 is connected and fixed to the slider 401 by fastening bolts 8.

[0029] In this embodiment, the lower surface of the movable plate 5 moves left and right along the upper surface of the rectangular frame 1 to stabilize the left and right movement of the movable plate 5, and the fastening bolt 8 allows the movable plate 5 and the slider 401 to be disassembled and assembled.

[0030] Specifically, the clamping mechanism 7 includes a second ball screw 701, a third bearing assembly 702, a second handle 703, a second ball nut 704, an arc-shaped clamping plate 705, and an anti-slip rubber pad 706. Two second ball screws 701 are arranged in a front-to-back mirror configuration, and their facing sides are fixedly connected. The second ball screws 701 are mounted on the front and rear side walls of the rectangular opening 6 via the third bearing assembly 702. A second handle 703 is fixedly mounted on each of the second ball screws 701 located outside the moving plate 5. A second ball nut 704 is provided on each of the second ball screws 701. An arc-shaped clamping plate 705 is fixedly mounted on the upper surface of each second ball nut 704, and an anti-slip rubber pad 706 is fixedly mounted on the facing sides of the front and rear arc-shaped clamping plates 705.

[0031] In this embodiment, the second handle 703 drives the front and rear second ball screws 701 to rotate in the front and rear third bearing assemblies 702. The rotation of the front and rear second ball screws 701 causes the front and rear second ball nuts 704 to move in opposite directions. The front and rear second ball nuts 704 drive the front and rear arc-shaped clamps 705 to move in opposite directions, so that the front and rear arc-shaped clamps 705 clamp and fix the outer surface of the pipe through the anti-slip rubber pads 706.

[0032] Specifically, the lower surface of the arc-shaped clamp 705 is movably attached to the upper surface of the movable plate 5.

[0033] In this embodiment, the lower surface of the arc-shaped clamp 705 moves back and forth along the upper surface of the movable plate 5, so that the back and forth movement of the arc-shaped clamp 705 is stable.

[0034] In use, the pipes to be joined are placed on the upper surfaces of the left and right movable plates 5 respectively. Then, the second handle 703 of the two clamping mechanisms 7 on the movable plates 5 drives the front and rear second ball screws 701 to rotate within the front and rear third bearing assemblies 702. The rotation of the front and rear second ball screws 701 causes the front and rear second ball nuts 704 to move in opposite directions. The front and rear second ball nuts 704 then drive the front and rear arc-shaped clamping plates 705 to move in opposite directions, allowing the arc-shaped clamping plates 705 to clamp and fix the outer surface of the pipes using anti-slip rubber pads 706. Each movable plate 5 is equipped with two sets of clamping mechanisms 7, making the pipe clamping more secure and capable of clamping pipes of various specifications. The first handle 304 in the drive mechanism 3 drives the transmission rod 302 to rotate in the first bearing assembly 303, which in turn drives the input shaft of the reducer 301 to rotate. The output shaft of the reducer 301 drives the first ball screw 305 to rotate. The rotation of the first ball screw 305 causes the first ball nut 307 to move left and right. The first ball nut 307 drives the slider 401 in the guide mechanism 4 to move on the guide rail 402. The slider 401 drives the moving plate 5 to move through the fastening bolt 8. The left and right moving plates 5 drive the left and right pipes to move towards each other through the clamping mechanism 7, so that the left and right pipes are joined together. This greatly improves the efficiency and quality of pipe joining, saves time and effort, and is convenient to use.

[0035] In summary, this high-pressure pipe quick-connection device can quickly clamp and fix the pipe, aligning it left and right, and can meet the clamping and fixing requirements of various pipes. At the same time, it allows the pipe to move and connect, greatly improving the efficiency and quality of pipe connection, saving time and effort, and making it easy to use.
