Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a pipe cutting and fixing device for building construction. Background Technology

[0002] Because precise cutting and secure fixing of pipes such as steel pipes and PVC pipes are required during construction to ensure dimensional accuracy and construction safety, a pipe cutting and fixing device for construction is established. This device is used to firmly clamp pipes of different specifications during cutting operations, preventing them from shifting or rotating. It also helps to accurately position the cutting location, improves pipe cutting efficiency and cut quality, and lays the foundation for subsequent pipe connection construction.

[0003] A search revealed Chinese Patent Publication No. CN222371747U, which discloses a pipe cutting and fixing device, relating to the field of pipe processing technology. The device includes a frame and a pipe body, with a processing table fixedly connected to the top of the frame. In this invention, when cutting the pipe body, with the pipe body clamped and fixed, a second electric push rod extends, causing a support block to move upwards. After moving upwards, the support block adheres to the inner wall of the pipe body. The support blocks on both sides can be positioned at the cutting position, providing support to the inner wall of the pipe body. When the pipe body is cut by a cutting machine, the cutting blade cuts through the pipe body between the two sides of the support block. Because the support blocks support the inner walls on both sides of the cutting position, when the outer wall of the pipe body contacts the cutting blade, it prevents the outer wall of the pipe body from denting due to instantaneous impact, effectively improving the yield rate of pipe cutting.

[0004] The aforementioned patent has the following shortcomings: Since the space between the two clamps of the above device is fixed, it is not convenient to flexibly adjust according to the processing range and blade position of different sized cutting equipment. As a result, when paired with larger cutting equipment, the clamps may block the cutting path and affect normal cutting operations. When paired with smaller cutting equipment, the clamp spacing is too wide, which cannot provide stable clamping for the pipe, thus causing the pipe to shift during cutting. This makes the pipe prone to shifting during the cutting process, resulting in low versatility of the device and difficulty in meeting the diverse cutting equipment and pipe processing scenarios in construction.

[0005] Therefore, a pipe cutting and fixing device for building construction is proposed. Utility Model Content

Detailed Implementation

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1: As Figures 1 to 5 As shown, a pipe cutting and fixing device for building construction includes a fixing frame 1, and further includes: The movable frame 5 is set on one side of the fixed frame 1; An extension structure 4 is provided between the movable frame 5 and the fixed frame 1. The extension structure 4 includes an extension frame 405 that is rotatably connected to one side of the fixed frame 1 and rotatably connected to the movable frame 5. A connecting shaft 402 is fixed to one side of the extension frame 405. A first retraction cylinder 401 is rotatably connected to the top of the connecting shaft 402. Guide components are provided on both sides of the bottom end of the extension frame 405. The worktable 2 is fixed to the top of the fixed frame 1 and the movable frame 5 respectively, and the top of the worktable 2 is fixed with a support roller 12. The top frame 6 is fixed on both sides of the top of the workbench 2. A hydraulic push rod 8 is fixed inside the top of the top of the top frame 6. A pressure plate 10 is fixed to the telescopic end of the hydraulic push rod 8. A pressure roller 11 is fixed to the bottom end of the pressure plate 10. A guide rod 7 connected to the pressure plate 10 is inserted inside the top of the top of the top frame 6. The lifting structure 3, used to push the tube apart from the support roller 12, is located at the bottom of the worktable 2; The flipping structure 9, used to drive the pipe to rotate between the pressure roller 11 and the support roller 12, is set on one side of the top of one of the worktables 2.

[0026] In this embodiment, when the device is used to cut pipes, the pipe to be processed is first placed on the support roller 12 at the top of the workbench 2. The support roller 12 provides initial support for the pipe. At the same time, the extension structure 4 pushes the moving frame 5 to adjust to a suitable position. The hydraulic push rod 8 drives the pressure plate 10 to move downward, so that the pressure roller 11 contacts the surface of the pipe. The guide rod 7 moves with the pressure plate 10 to guide it and prevent the pressure plate 10 from shifting. This allows the pressure roller 11 and the support roller 12 to cooperate to clamp and fix the pipe, which to a certain extent ensures that the pipe will not shake during the subsequent cutting process, providing a basis for cutting accuracy. The flipping structure 9 drives the pipe to rotate during the cutting process, making the pipe cut flat. After the pipe is released from fixation, the hydraulic push rod 8 drives the pressure roller 11 and the lifting structure 3 to move upward. The lifting structure 3 facilitates the movement of the pipe position.

[0027] like Figures 1 to 4 As shown, the guide assembly includes sliders 404 installed on both sides of the bottom end of the extension frame 405. The interior of the fixed frame 1 and the movable frame 5 is respectively provided with a sliding groove 403 that is slidably connected to the sliders 404. Universal wheels 406 are installed at the four corners of the bottom end of the movable frame 5. The front cross-section of the extension frame 405 is an "X" shaped structure, and the extension frame 405 can extend and retract by changing its own cross angle.

[0028] In this embodiment, when it is necessary to adapt to cutting equipment of different sizes, the first retraction cylinder 401 is activated to extend or retract, causing the first retraction cylinder 401 to drive the extension frame 405 to move through the connecting shaft 402. Then, the extension frame 405 achieves extension and retraction by changing the cross angle of its own "X"-shaped structure. At the same time, the slider 404 slides in the slide groove 403 to provide guidance for the extension and retraction of the extension frame 405, so that the moving frame 5 moves with the extension and retraction of the extension frame 405, thereby adjusting the distance between the fixed frame 1 and the moving frame 5. The universal wheel 406 at the bottom of the moving frame 5 reduces the resistance when the moving frame 5 moves, which improves the flexibility of the device distance adjustment to a certain extent, making it adaptable to more construction scenarios.

[0029] Example 2: A pipe cutting and fixing device for building construction. This example is an improvement on Example 1, as follows: Figures 1 to 4As shown, the lifting structure 3 includes a limiting sleeve 304 fixed to the bottom of the workbench 2. A movable plate 302 is provided at the top of the inside of the limiting sleeve 304. Lifting rollers 305 are fixed on both sides of the top of the movable plate 302. Lifting rods 301, which are fixedly connected to the pressure plate 10, are slidably connected to the inside of both sides of the movable plate 302. A lifting plate 303 is fixed at the bottom of the lifting rod 301. The lifting rod 301 passes through the workbench 2 and extends to the bottom of the movable plate 302 and connects with the lifting plate 303. The lifting rods 301 are symmetrically distributed on the vertical center line of the movable plate 302. The end of the first retraction cylinder 401 away from the connecting shaft 402 forms a rotating structure with the limiting sleeve 304. An arc-shaped groove is provided on the outer wall of the lifting roller 305.

[0030] In this embodiment, when it is necessary to adjust the position of the pipe on the workbench 2 or replace the pipe, the hydraulic push rod 8 is controlled to retract, causing the pressure plate 10 to move upward. At the same time, the lifting rod 301 moves with the pressure plate 10, driving the lifting plate 303 to move upward. The lifting plate 303 pushes the moving plate 302 upward, so that the lifting roller 305 contacts the pipe and lifts the pipe, separating it from the support roller 12. The rolling of the lifting roller 305 makes it convenient for the staff to push the pipe to adjust its position or remove the pipe. To a certain extent, it reduces the friction between the pipe and the support roller 12 when the pipe moves, reducing the risk of damage to the pipe surface.

[0031] like Figures 1 to 4 As shown, the flipping structure 9 includes a flipping frame 905 rotatably connected to one side of the top of the workbench 2. A roller frame 903 is fixed to the top of the flipping frame 905. A rubber roller 901 is rotatably connected to the inside of the top of the roller frame 903. An electromagnetic brake 902 connected to the rotating shaft of the rubber roller 901 is installed on one side of the roller frame 903. A reduction motor 906 whose output shaft end is connected to the rotating shaft of the rubber roller 901 is installed on the other side of the roller frame 903. A second retraction cylinder 904 whose telescopic end is rotatably connected to the top of the workbench 2 is rotatably connected to the flipping frame 905. Anti-slip patterns are provided on the outer side wall of the rubber roller 901, and the anti-slip patterns are arranged at equal intervals on the outer side wall of the rubber roller 901.

[0032] In this embodiment, when it is necessary to perform circumferential cutting on the outer periphery of the pipe, the second shrink cylinder 904 is activated to extend or retract, causing it to pull the flipping frame 905 to rotate. At the same time, the flipping frame 905 drives the rubber roller 901 to make close contact with the surface of the pipe. The reduction motor 906 is activated to drive the rubber roller 901 to rotate. The rubber roller 901 increases the friction between itself and the pipe through the anti-slip texture on its outer wall, thereby driving the pipe to rotate around the axis between the pressure roller 11 and the support roller 12. If it is necessary to stop the rotation of the pipe, the electromagnetic brake 902 can be activated to brake the rubber roller 901, which to a certain extent ensures the stability and controllability of the pipe during rotation and meets the needs of multi-angle cutting of the pipe.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
