Description

Technical Field

[0001] This utility model belongs to the field of pipeline cutting technology, specifically relating to a pipeline cutting device for municipal engineering. Background Technology

[0002] In municipal engineering construction, especially in urban sewage pipe network renovation and expansion projects, it is often necessary to cut large-diameter sewage pipes on-site to remove excess parts or adjust the pipe layout. Traditional methods mostly use manual cutting or large-scale mechanical cutting. The former is labor-intensive, inefficient, and difficult to guarantee accuracy, while the latter has disadvantages such as bulky equipment, inconvenient transportation, difficult on-site setup, and high cost. Therefore, this utility model provides a municipal engineering pipe cutting device that has a simple structure, is easy to operate, and can quickly and efficiently complete the on-site cutting of large-diameter sewage pipes.

[0014] 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.

[0015] Example

[0016] Please see Figure 1-2This utility model provides the following technical solution: a municipal engineering pipe cutting device, including a wire saw cutting mechanism, a distance adjustment mechanism, and a control mechanism. The distance adjustment mechanism includes an installation platform 1, which ensures the stability of the entire device during operation. A fixing component is provided at the bottom of the installation platform 1 to prevent shaking or displacement during the cutting process. A housing 2 is fixed to the top of the installation platform 1, serving as a protective cover for the internal mechanical structure. A screw 3 is installed inside the housing 2, with a drive motor 4 installed at one end of the screw 3. The drive motor 4 is fixed to the installation platform 1 and drives the screw through the screw. The rotation of the machine 4 can drive the screw 3 to rotate; both ends of the screw 3 are equipped with nut seats 5, and the threads at both ends of the screw 3 are opposite, as are the internal threads of the nut seats 5. A slide table 6 is fixed on the top of the nut seat 5, and the slide table 6 is slidably connected to the housing 2, ensuring that the slide table 6 can move smoothly along the guide of the housing 2; the wire saw cutting mechanism includes a drive flywheel 7, a guide wheel 8, and a wire saw body 9. The drive flywheel 7 and the guide wheel 8 are respectively installed on the slide table 6 on the top of the two nut seats 5. As the nut seats 5 drive the slide table 6 to move, the drive flywheel 7 and the guide wheel 8 will also move accordingly. The wire saw body 9 is mounted on the drive flywheel 7 and guide wheel 8 to achieve rotary cutting of the pipe. The control mechanism includes a controller and a tension sensor 10. The controller is electrically connected to the tension sensor 10 and the drive motor 4. The wire saw body 9 is mounted on the drive flywheel 7, guide wheel 8, and tension sensor 10, passing through the tension sensor 10. The tension sensor 10 is responsible for monitoring the tension of the wire saw body 9 in real time and transmitting the data to the controller. The controller then adjusts the speed and direction of the drive motor 4 based on the received data, thereby controlling the tension adjustment of the wire saw body 9 to ensure the accuracy and safety of the cutting process.

[0017] To facilitate the fixed installation of platform 1, in this embodiment, as a preferred technical solution of the present invention, the fixing component includes a base 11 and a hand-tightening bolt 12. The base 11 and the bottom end face of the installation platform 1 are slidably connected, the hand-tightening bolt 12 and the end of the installation platform 1 are threadedly connected, and the hand-tightening bolt 12 and the base 11 are arranged collinearly. An extension clamp 13 is connected to the bottom end of the base 11.

[0018] To ensure the stability of the fixation, in this embodiment, as a preferred technical solution of the present invention, the extension clamp 13 and the base 11 are telescopic structures, and both the extension clamp 13 and the base 11 are provided with fixing holes. The extension clamp 13 and the base 11 are fastened together by bolts passing through the fixing holes, and an anti-slip pad 14 is fixed on the inner wall of the extension clamp 13.

[0019] In order to ensure cooling of the cutting part, in this embodiment, as a preferred technical solution of the present invention, cooling water pipes 15 are fixed on both sides of the base 11.

[0020] In summary, by adopting the technical solution of this utility model, during operation, the installation platform 1 must first be placed above the pipe, and the downward extension length of the extension clamp 13 should be adjusted so that its bottom contacts the ground. Then, the extension clamp 13 is fastened to the base 11 using bolts. By rotating the hand-tightening bolts 12 on both sides, the position of the base 11 can be precisely adjusted so that the extension clamp 13 at the bottom of the base 11 tightly clamps the pipe, achieving a stable fixation of the pipe. Next, the wire saw body 9 is wound around the surface of the pipe, and the drive flywheel 7 is started to drive the wire saw body 9 to rotate to perform the pipe cutting operation. During the cutting process, tap water from the cooling water pipe 15 will cool the cutting area along the wire saw body 9. As the cutting depth increases, the length of the wire saw body 9 will increase accordingly, which may lead to insufficient tension. At this time, the tension sensor 10 will detect the tension state of the wire saw body 9 in real time and convert the detected information into an electrical signal and transmit it to the controller. The controller controls the drive motor 4 to drive the screw 3 to rotate according to the received electrical signal. Because the screw 3 has a reverse thread, when the screw 3 rotates, the two nut seats 5 will drive the drive flywheel 7 and guide wheel 8 to move closer or further apart through the slide table 6, thereby achieving precise adjustment of the tension of the wire saw body 9 and ensuring that the wire saw body 9 can maintain a stable rotating cutting state.

[0021] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
