Description

Technical Field

[0001] This utility model relates to the field of cutting devices for building construction, and in particular to a cutting device for civil engineering structure construction. Background Technology

[0002] Construction slit cutting devices are devices used on construction sites to cut slits in the ground for subsequent operations. They are widely used in the construction industry. Existing construction slit cutting devices include a motor and a cutting wheel, with the motor output connected to the central area of ​​the rear side wall of the cutting wheel.

[0003] Chinese utility model patent CN212052251U discloses a cutting device for civil engineering construction. It features a movable plate, double-column handles, a universal rod, and a protective platform. By holding the double-column handles and pushing the movable plate along the protective platform, a moving block drives a support plate to slide along a strip groove, allowing the cutting wheel to cut slits. This significantly reduces the labor intensity of workers and improves efficiency. Furthermore, the track groove and strip groove constrain the cutting trajectory of the cutting wheel, resulting in uniform slits and reducing the manpower and resources required for subsequent grinding.

[0004] However, in the existing design, the height adjustment of the support columns needs to be done manually one by one. This is not only time-consuming and laborious, but may also lead to inconsistent heights between the support columns, affecting the stability of the equipment. Furthermore, when manually adjusting the support columns, tilting or instability is likely to occur, which may cause the cutting wheel to suddenly contact the ground, resulting in impact or damage.

[0005] Therefore, it is necessary to provide a new cutting device for civil engineering construction to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a cutting device for civil engineering construction.

[0007] The cutting device for civil engineering construction provided by this utility model includes a base plate, a counterweight block fixedly connected to one side of the top of the base plate, a protective platform fixedly connected to the top of the counterweight block, and a reduction motor provided between the base plate and the protective platform. A cutting wheel is fixedly connected to the output end of the reduction motor. Fixed bases are detachably connected to the four outer corners of the base plate by bolts. Support columns are slidably connected to the inner wall of the fixed bases. A driving component is provided inside the counterweight block. The driving component passes through the counterweight block and is fixedly connected to a threaded rod. A lifting bracket is threadedly connected to the outer surface of the threaded rod. The lifting bracket is connected to the four support columns respectively.

[0008] Furthermore, a DC groove is provided through the side wall of the counterweight block, and a trapezoidal block is fixedly connected to the bottom of the DC groove. A rectangular groove is provided through the side wall of the trapezoidal block.

[0009] Furthermore, the driving component includes a drive motor, which is fixedly connected to the top of the trapezoidal block. The output end of the drive motor is fixedly connected to a threaded rod. The upper end of the threaded rod is rotatably connected to the trapezoidal block through a threaded sleeve. The lower end of the threaded rod is threadedly connected to a lifting bracket. Both ends of the lifting bracket are in contact with the inner wall of the rectangular groove.

[0010] Furthermore, the top of the lifting bracket is provided with an annular groove, the radial dimension of which matches the support column. The outer wall of the lifting bracket is threaded with a screw rod, which passes through the annular groove and fits against the outer surface of the support column. One end of the support column is also embedded with a ball bearing.

[0011] Furthermore, two mounting slots are respectively opened at both ends of the base plate, and the outer wall of the fixed base is placed in the mounting slot of the base plate.

[0012] Furthermore, a strip groove is provided on the side of the base plate and the protective platform away from the counterweight, and a sliding housing is slidably connected between the two strip grooves, with the bottom of the geared motor fixedly connected to the sliding housing.

[0013] Furthermore, a universal rod is installed on the top of the sliding housing, and a double-post handle is fixedly connected to one end of the universal rod.

[0014] Compared with related technologies, the cutting device for civil engineering structure construction provided by this utility model has the following beneficial effects:

[0015] This cutting device for civil engineering construction can change the height of the base plate from the ground by fixing the position of the support column on the lifting bracket, thereby improving the flexibility when facing the cutting wheel and the required cutting depth.

[0016] By marking the areas requiring slits, and aligning one side of the base plate with the marked lines, the drive motor is activated. The drive motor rotates the threaded rod, which in turn moves the lifting bracket up and down in a threaded manner. During this process, the lifting bracket slides within a rectangular groove, providing vertical guidance. As the distance between the lifting bracket and the base plate increases, the distance between the base plate and the ground decreases, causing the slit-cutting wheel to slowly move towards the ground. Activating the reduction motor then rotates the slit-cutting wheel, initiating the cutting along the marked areas. Compared to manual adjustments, this method, where the drive motor drives the lifting bracket to simultaneously raise and lower four support columns, reduces manual adjustments, improves operational convenience and efficiency, and ensures equipment stability and slit precision.

[0024] In the specific implementation process, such as Figures 1 to 4As shown, the cutting device for civil engineering construction provided by this utility model includes a base plate 1, a counterweight 2 fixedly connected to one side of the top of the base plate 1, a protective platform 4 fixedly connected to the top of the counterweight 2, and a reduction motor 8 disposed between the base plate 1 and the protective platform 4. A cutting wheel 9 is fixedly connected to the output end of the reduction motor 8. A strip groove is formed on the side of the base plate 1 and the protective platform 4 away from the counterweight 2. A sliding housing 5 is slidably connected between the two strip grooves. The bottom of the reduction motor 8 is fixedly connected to the sliding housing 5, and a cutting wheel 9 is installed on the top of the sliding housing 5. There is a universal rod 6, one end of which is fixedly connected to a double-column handle 7. Two mounting slots are opened at both ends of the base plate 1. The outer wall of the fixed base 10 is placed in the mounting slot of the base plate 1. The four outer corners of the base plate 1 are detachably connected to the fixed base 10 by bolts. The inner wall of the fixed base 10 is slidably connected to the support column 11. The counterweight 2 is equipped with a driving component. The driving component passes through the counterweight 2 and is fixedly connected to a threaded rod 14. The outer surface of the threaded rod 14 is threadedly connected to a lifting bracket 15. The lifting bracket 15 is connected to the four support columns 11 respectively.

[0025] The counterweight 2 is fixed to one side of the top of the base plate 1 to increase the stability of the device and prevent displacement caused by vibration during the cutting process.

[0026] The geared motor 8 is installed between the base plate 1 and the protective platform 4, and its output end is fixedly connected to the cutting wheel 9, which is responsible for driving the cutting wheel 9 to rotate.

[0027] The counterweight 2 has a through-hole DC groove on its side wall. A trapezoidal block 3 is fixedly connected to the bottom of the DC groove. A rectangular groove is through-hole on the side wall of the trapezoidal block 3. The driving component includes a drive motor 13, which is fixedly connected to the top of the trapezoidal block 3. The output end of the drive motor 13 is fixedly connected to a threaded rod 14. The upper end of the threaded rod 14 is rotatably connected to the trapezoidal block 3 through a threaded sleeve. The lower end of the threaded rod 14 is threadedly connected to a lifting bracket 15. The two ends of the lifting bracket 15 are fitted with the inner wall of the rectangular groove and are detachably connected to the four outer corners of the base plate 1 by bolts. A support column 11 is slidably connected to the inner wall for adjusting the height of the base plate 1.

[0028] The top of the lifting bracket 15 has a through-hole annular groove, the radial dimension of which matches the support column 11. The outer wall of the lifting bracket 15 is threaded with a screw 16, which passes through the annular groove and fits against the outer surface of the support column 11. One end of the support column 11 is also embedded with a ball bearing 12, which reduces friction and improves the smoothness of sliding.

[0029] The working principle of this utility model is as follows: In specific implementation, by fixing the position of the support column 11 on the lifting bracket 15 in advance, the height of the base plate 1 from the ground can be changed, improving the flexibility when facing the cutting wheel 9 to cut at different depths. Then, the part to be cut is marked, and one side of the base plate 1 is aligned with the marked line. By starting the drive motor 13, the drive motor 13 drives the threaded rod 14 to rotate, and the threaded rod 14 drives the lifting bracket 15 to move up and down in a threaded manner. During the lifting process, the lifting bracket 15 will slide in the rectangular groove, thereby providing vertical guidance for the lifting bracket 15. As the distance between the lifting bracket 15 and the base plate 1 increases, the distance between the base plate 1 and the ground decreases, thereby causing the cutting wheel 9 to slowly move towards the ground. By starting the reduction motor 8, the cutting wheel 9 is driven to rotate, so that the cutting wheel 9 begins to cut along the marked part.
