[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0023] Please see Figures 1-6 This utility model provides the following technical solution: a slit cutting device for a slipform paver tooth wall mold, including a slipform paver 3. The slipform paver 3 is connected to a hydraulic lift 1 on one side of the paver body via a frame 2. A slit cutting mechanism 4 is installed on the slipform paver 3 via the frame 2. The slit cutting mechanism 4 includes a cutter drive cylinder 41, a cutter assembly 5, and a pressing and shaping guard plate 6. A cutter fixing seat 44 is installed on the top of the cutter assembly 5. The two ends of the cutter fixing seat 44 slide on the slide rails 42 on both sides of the slit cutting mechanism 4 via limiting sliders 43. The front and rear surfaces of the limiting slider 43 are connected with a pressing and shaping guard plate 6, and the two sides of the cutting assembly 5 are integrally formed with elastic extrusion plates 52. During the concrete slipform construction, the cutting assembly 5, in conjunction with the pressing and shaping guard plate 6, directly cuts the uncured concrete, ensuring the integrity of the cut edges and the inner surface of the cut. This reduces the difficulty of construction and avoids secondary construction. It can be operated in conjunction with the material gap of slipform construction without affecting the normal continuous slipform construction operation. It can effectively save time during the construction process, thereby improving the efficiency of construction.
[0024] Specifically, the compression molding guard plate 6 includes an upper pressure plate 61, with a compression template 64 adapted to the concrete structure 10 at its bottom; guide rods 62 are provided at both ends of the upper pressure plate 61, with the upper end of the guide rod 62 sliding within the limiting hole of the connecting plate 65, and a compression spring 63 connected to the upper pressure plate 61 and the connecting plate 65 sleeved at the lower end of the guide rod 62; the upper pressure plate 61 is positioned close to both sides of the cutter assembly 5; a cutter drive cylinder 41 connected to the top of the cutter fixing seat 44 is installed on the top of the cutting mechanism 4; the cutter is activated. The driving cylinder 41 drives the limiting slider 43 to move downward along the slide rail 42, thereby driving the pressing plastic protective plate 6 to move downward until the upper pressure plate 61 on the pressing plastic protective plate 6 presses on the upper surface of the concrete structure 10, and the pressing template 64 is attached to both sides of the concrete structure 10; this ensures the integrity of the top surface and both sides of the concrete structure 10 during the cutting process. The uncured concrete is easily deformed and cracked or partially collapsed by the squeezing force of the cutter cutting into the stone or the force of the cutter pulling out.
[0025] Specifically, the cutter assembly 5 has grooves on both sides, and the lower end of the elastic compression plate 52 is installed at the groove opening. The upper back of the elastic compression plate 52 is provided with a compression spring 53 connected to the inside of the groove. The bottom of the cutter assembly 5 is provided with a blade 51. The elastic compression plate 52 is made of stainless steel that does not easily stick to concrete. The height of the elastic compression plate 52 is higher than the height of the concrete structure 10. The limiting slider 43 drives the cutter assembly 5 downward to cut into the concrete structure 10. After the cutter assembly 5 cuts, the elastic compression plates 52 on both sides of the cutter assembly 5, together with the compression spring 51, compress the inner side of the cut, thereby ensuring the flatness of the inner side of the cut and preventing the collapse of the inner side of the cut.
[0026] Specifically, the cutter assembly 5 and the pressing and shaping guard plate 6 are driven by the cutter drive cylinder 41 to move up and down along the slide rail 42.
[0027] In addition, the frame 2 is equipped with an electrical control box that is electrically connected to the hydraulic lift 1 and the cutter drive cylinder 41; the electrical control box is used to supply power.
[0028] The working principle and usage process of this utility model are as follows: In use, the hydraulic lift 1, via the frame 2, adjusts the height of the slipform paver 3 and the cutting mechanism 4. The slipform paver 3 lays the concrete structure 10 flat on the ground. The cutting mechanism 4, perpendicular to the concrete structure 10, cuts slits according to the different lengths of the concrete structure 10. When the cutting mechanism 4 reaches the required cutting position, the slipform paver 3 first stops its forward movement, then the cutter drive cylinder 41 is activated. The movable limit slider 43 moves downward along the slide rail 42, thereby driving the pressing and shaping guard plate 6 downward until the upper pressure plate 61 on the pressing and shaping guard plate 6 presses against the upper surface of the concrete structure 10, and the pressing template 64 is attached to both sides of the concrete structure 10. This ensures the integrity of the top surface and both sides of the concrete structure 10 during the cutting process, and avoids deformation, cracking, or partial collapse of the concrete surface around the cut opening caused by the squeezing force of the cutter entering and squeezing the stone or the force of the cutter pulling out. The limit slider 43 drives the cutter assembly 5 downward to cut into the concrete structure 10. After the cutter assembly 5 cuts, the elastic compression plates 52 on both sides of the cutter assembly 5, together with the compression spring 51, compress the inner side of the cut, thereby ensuring the flatness of the inner side of the cut and preventing the collapse of the inner side of the cut. The above process is repeated until all the cutting construction of the concrete structure 10 is completed. By using the cutting mechanism 4, the cutting blade assembly 5, and the pressing and shaping guard plate 6 in conjunction with the cutting construction, the construction difficulty is reduced while avoiding secondary construction. It can be operated in conjunction with the material gap of slipform construction without affecting the normal continuous slipform construction operation. It can effectively save time during the construction process, thereby improving the construction efficiency.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
