Description
Technical Field
[0001] This application relates to the field of engineering processing technology, and in particular to a cutting device for engineering materials used in municipal engineering. Background Technology
[0002] With the development of municipal engineering, the cutting and processing of various engineering materials plays a crucial role in the construction process. Municipal engineering often involves the on-site or prefabrication of various materials such as pipes, plates, and profiles, which places high demands on the stability, flexibility, and ease of operation of cutting equipment.
[0003] A search revealed a building material cutting device in Chinese Patent Publication No. CN117549367B. This device includes a fixed worktable, a movable worktable, an adaptive clamping mechanism, a cutting mechanism, and an adjustable chamfering and unloading mechanism. Material is pushed through a sliding connection between the movable and fixed worktables, and the adaptive clamping mechanism securely fixes workpieces with uneven surfaces. A bi-directional rotating plate enables chamfering and automatic unloading. While this design improves upon fixed positioning and multi-functional integration, its complex structure relies on multiple linkage mechanisms, resulting in a large overall size that is inconvenient for movement and deployment in confined spaces at municipal construction sites. Furthermore, its clamping mechanism is a mechanical adaptive structure with a limited adjustment range, making it difficult to adapt to the general cutting needs of engineering materials of different thicknesses and materials (such as metal pipes, precast concrete components, and PVC pipes), thus limiting its flexibility and applicability in on-site operations.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following shortcomings: Existing building material or sheet metal cutting devices generally suffer from fixed structures, poor adaptability, inconvenient adjustment, and insufficient flexibility in on-site operation, making it difficult to simultaneously meet the comprehensive needs of municipal engineering projects involving multiple materials, multiple scenarios, high efficiency, and portability. Therefore, there is an urgent need to provide a municipal engineering material cutting device with a reasonable structure, convenient adjustment, and wide applicability to improve on-site construction efficiency and operational safety.

Detailed Implementation
[0021] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0022] This application discloses an engineering material cutting device for municipal engineering. For example... Figure 1 As shown, this device includes a frame 1, a lifting and cutting assembly 2, and a movable material platform 3. The frame 1 serves as the core support framework of the entire device, providing a stable foundation for other components. The lifting and cutting assembly 2 is mounted on one end of the top of the frame 1 for performing cutting tasks; the movable material platform 3 is located on the other end for pushing the materials to be cut. This layout makes the overall structure of the device compact, facilitating its placement and use in confined spaces. Of particular note is that angle steel 11 is welded to both sides of the frame 1 near the lifting and cutting assembly 2, and the angle steel 11 are connected by an upper shaft 12, providing a reliable fulcrum for the rotational adjustment of the lifting and cutting assembly 2. A tie rod 14 is also provided at the end of the frame 1 away from the movable material platform 3. The tie rod 14 works in conjunction with the lifting and cutting assembly 2 to achieve flexible adjustment of the tilt angle. To ensure the stable operation of the movable material platform 3, rails 16 are bolted to both sides of the top of the frame 1, allowing the movable material platform 3 to slide along the rails.
[0023] Please see Figure 4 The lifting and cutting assembly 2 includes an inclined mounting plate 21, a motor 22, a cutting disc 23, and a transmission system. The design of the inclined mounting plate 21 is a major innovation of this device. Its bottom end near the angle steel 11 is rotatably connected to the upper shaft 12 via a bushing, while the other end is rotatably connected to the top of the pull rod 14 via a rotating shaft, forming a lever structure. This design allows the lifting and cutting assembly 2 to be adjusted in height as needed, thus adapting to engineering materials of different thicknesses. The motor 22 is mounted on the top end of the inclined mounting plate 21 near the pull rod 14. The motor 22 drives the first pulley 24 to rotate via a drive shaft. The first pulley 24 is connected to a second pulley 25 via a belt, and the second pulley 25 is mounted on the rotating shaft of the cutting disc 23, thereby transmitting power to the cutting disc 23. To ensure operator safety, protective covers are provided on the top of the cutting disc 23 and around the first pulley 24 and the second pulley 25. These protective covers are securely connected to the inclined mounting plate 21 via bolts, effectively isolating dangerous components.
[0024] Please see Figure 3 , 5A tripod 13 is installed at the bottom of the frame 1 near the pull rod 14. The bottom of the tripod 13 is rotatably connected to the frame 1 via a pivot, and one end is rotatably connected to the bottom of the pull rod 14 via a pivot. The design of the tripod 13 provides additional support for the lifting and cutting assembly 2, ensuring its stability during adjustment. Meanwhile, an electric push rod 15 is rotatably connected to the bottom of the frame 1 away from the pull rod 14 via a pivot. The output end of the electric push rod 15 is rotatably connected to the other end of the tripod 13 via a pivot. The control switch for the electric push rod 15 is a foot switch, located below the frame 1 near the movable material table 3, allowing the operator to easily adjust the height during cutting. The extension and retraction of the electric push rod 15 pushes the tripod 13 to swing, thereby causing the lifting and cutting assembly 2 to rotate around the upper shaft 12, achieving height adjustment of the cutting disc 23. This electric adjustment method is not only easy to operate but also significantly improves the accuracy and efficiency of adjustment.
[0025] Please see Figure 1 , 6 The structure of the moving material platform 3 is as follows Figure 1 and Figure 6 As shown, the main components include a push plate 31, track wheels 32, a material placement platform 311, and a fixing structure. Track wheels 32 are rotatably mounted on both ends of the bottom of the push plate 31 via bearings. The track wheels 32 are positioned on tracks 16 on both sides of the top of the frame 1, allowing the push plate 31 to slide smoothly along the tracks 16. Two sets of material placement platforms 311 are bolted to the top ends of the push plate 31, forming a cutting groove 33 corresponding to the cutting disc 23 between the material placement platforms 311 for placing the material to be cut. To prevent material slippage, a baffle 34 is bent at the end of the material placement platform 311 away from the lifting cutting assembly 2. A side baffle 35 is also provided on the top of one set of material placement platforms 311. One end of the side baffle 35 is screwed to the corresponding baffle 34 via a threaded knob 36, further securing the material and ensuring stability during the cutting process. This design not only achieves high efficiency in material pushing but also ensures safety during the cutting process through a multi-layer fixing structure.
[0026] The implementation principle of the engineering material cutting device for municipal engineering in this embodiment is as follows: The engineering material to be cut is placed on the material placement platform 311 of the movable material platform 3. The push plate 31 slides along the track 16 to push the material to the bottom of the cutting disc 23. Then, the extension and retraction of the electric push rod 15 is controlled by a foot switch, which pushes the tripod 13 to swing, thereby driving the lifting cutting assembly 2 to rotate around the upper shaft 12, realizing the height adjustment of the cutting disc 23. After the height adjustment is completed, the motor 22 is started. The motor 22 drives the first pulley 24 to rotate through the drive shaft. The first pulley 24 is connected to the second pulley 25 through a belt, thereby transmitting power to the cutting disc 23, causing the cutting disc 23 to rotate at high speed. At this time, the cutting disc 23 can cut the engineering material. During the cutting process, the protective cover effectively isolates the cutting disc 23 and the transmission components, preventing operators from contacting dangerous parts and ensuring operational safety.
[0027] Furthermore, the frame 1, through the design of angle steel 11 and upper shaft 12, enhances overall rigidity and structural stability, while providing a reliable rotation fulcrum for the lifting and cutting assembly 2. The lifting and cutting assembly 2 adopts an inclined lever design, combined with an electric push rod 15 to achieve height adjustment, significantly improving the convenience of adjustment. The moving material platform 3, through the design of track wheels 32 and track 16, achieves efficient and stable material pushing, while the fixed structure of the material placement platform 311 further ensures the stability of the material during the cutting process. The design of the protective cover effectively isolates the cutting disc 23 and transmission components, ensuring the safety of the operator.
[0028] This application achieves a compact and modular design through the rational design of the frame 1, the lifting and cutting assembly 2, and the moving material platform 3, facilitating arrangement and operation in confined spaces. The inclined lever design of the lifting and cutting assembly 2, combined with the electric push rod 15, significantly improves the ease of adjusting the cutting height. The track design of the moving material platform 3 and the fixed structure of the material placement platform 311 ensure the efficiency and stability of the material pushing and cutting process. The protective cover design effectively isolates hazardous components, ensuring the safety of operators. In summary, this device provides a municipal engineering material cutting device with a reasonable structure, convenient adjustment, wide applicability, and safe operation, which can significantly improve on-site construction efficiency and operational safety.
[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
