Description

Technical fields:

[0001] This utility model relates to the field of slit cutting technology, specifically to an automatic hydraulic slit cutting device for concrete slipform. Background technology:

[0002] During slipform construction of concrete structures, it is necessary to cut grooves in the formed concrete to reduce cracking caused by temperature changes or stress concentration later on. Existing slipform cutting devices for concrete often have the following shortcomings: low positioning accuracy of the cutting blade, which is prone to deviation due to shaking; concrete slurry tends to stick to the blade surface during cutting, increasing cutting resistance and affecting the regularity of the cut; and insufficient overall stability of the device, making it difficult to guarantee the cutting depth and perpendicularity. Utility model content:

[0003] Therefore, this utility model provides an automatic hydraulic cutting device for concrete slipform, in order to overcome the problems of the prior art.

[0004] This utility model is implemented by the following technical solution:

[0005] An automatic hydraulic slitting device for concrete slipform molding includes a mounting base on which a slipform forming mold is fixed. The slipform forming mold is used for forming concrete structures. A guide slot is fixed to the upper end of the tail of the slipform forming mold. A mold ventilation slot is fixed on the slipform forming mold, and the mold ventilation slot is correspondingly arranged with the guide slot. A slitting cutter can be inserted into the guide slot. The slitting cutter is fixed on a cutter holder and positioned at the upper end of the guide slot. The slitting cutter can pass through the guide slot and the mold ventilation slot in sequence and be inserted into the formed concrete structure. A hydraulic telescopic rod is fixedly connected to the top of the cutter holder. The hydraulic telescopic rod is fixedly connected to a positioning frame through a connecting frame. The positioning frame is fixed on the slipform forming mold.

[0006] Preferably, the two sides of the cutting blade are fixedly provided with several parallel shallow grooves along the cutting direction.

[0007] Preferably, a plurality of elastic scraping components are respectively provided on the top two sides of the guide slot, and each elastic scraping component is provided corresponding to each shallow groove, and one end of the elastic scraping component can be inserted into the shallow groove.

[0008] Preferably, the elastic scraping assembly includes an elastic hinge and a scraper. The elastic hinge is hinged to the top side of the guide slot, and the scraper is fixedly connected to the elastic hinge. The scraping end of the scraper can be inserted into the shallow groove.

[0009] Preferably, the scraping end of the scraper is configured in an inverted V shape.

[0010] Preferably, the elastic hinge includes a hinge shaft and an angle spring. The hinge shaft is hinged to the top side of the guide slot, and the angle spring is sleeved on the hinge shaft. One end of the angle spring is fixedly connected to the scraper.

[0011] Preferably, a vibrator is fixed on the tool holder.

[0012] Preferably, a limiting groove is fixed on the side of the positioning frame, a limiting rod is slidably connected in the limiting groove, and the side end of the limiting rod is fixedly connected to the tool holder.

[0013] The advantages of this invention are as follows: The hydraulic telescopic rod is fixed to the slipform forming mold by the positioning frame, and the guide slot guides the cutting blade, ensuring that the cutting blade moves along a fixed path, avoiding cutting deviation, and improving the verticality and straightness of the cutting. At the same time, the hydraulic telescopic rod drives the cutting blade to complete the cutting action without manual intervention, reducing labor intensity.

[0018] 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.

[0019] like Figure 1 , Figure 2 As shown, an automatic hydraulic cutting device for concrete slipform includes a mounting base 1, which is a rigid base used to support the weight of the entire device and fix it to the construction platform.

[0020] The mounting base 1 is fixed with a slipform forming mold 2 by bolts. The slipform forming mold 2 has a groove-shaped structure, and its inner cavity is adapted to the shape of the concrete structure 6 to be formed, and is used for the initial forming after the concrete is poured.

[0021] The upper end of the tail of the slipform forming mold 2 is fixed with a guide slot 4. The guide slot 4 is a rectangular channel with baffles on both sides, and its axis is perpendicular to the length direction of the slipform forming mold 2.

[0022] The sliding mold 2 has a mold ventilation slot 5 at the tail corresponding to the guide slot 4. The mold ventilation slot 5 is a long strip-shaped through hole with the same width as the inner cavity width of the guide slot 4 and the two axes are collinear, ensuring that the cutting knife 3 can pass through smoothly.

[0023] The cutting blade 3 is a rectangular blade structure, and its thickness is slightly smaller than the inner cavity width of the guide slot 4. The blade is set with the blade facing downward. The top of the cutting blade 3 is fixed to the blade holder by bolts, and the blade holder is located directly above the guide slot 4.

[0024] The cutting blade 3 has several parallel shallow grooves machined on both sides along its length direction, i.e. the cutting direction, to reduce the contact area with the uncured concrete.

[0025] Several elastic scraping components 11 are installed on the top two sides of the guide slot 4 via hinge seats, and the number of elastic scraping components 11 corresponds one-to-one with the shallow groove.

[0026] The elastic scraping assembly 11 includes an elastic hinge 12 and a scraper 13. The elastic hinge 12 consists of a hinge shaft and an angle spring. The hinge shaft is fixed to the top side of the guide slot 4, and the angle spring is sleeved on the hinge shaft. One end of the angle spring abuts against the side of the guide slot 4, and the other end is welded and fixed to the scraper 13. The scraper 13 is made of wear-resistant steel, and its scraping end is machined into an inverted V-shape with the tip pointing towards the shallow groove. In its natural state, it is inserted into the shallow groove under the elastic force of the angle spring and fits against the inner wall of the groove.

[0027] A vibrator is bolted to one side of the tool holder to generate high-frequency vibration during the cutting process, reducing cutting resistance. The center of the top of the tool holder is fixedly connected to the telescopic end of the hydraulic telescopic rod 7 via a flange. The fixed end of the hydraulic telescopic rod 7 is bolted to the positioning frame 8 via a connecting bracket. The positioning frame 8 has an L-shaped structure, and its bottom is fixed to the side of the slipform forming mold 2 via expansion bolts.

[0028] The side of the positioning frame 8 is fixed with a limiting groove 9, the length of which is consistent with the extension direction of the hydraulic telescopic rod 7. A limiting rod 10 is slidably connected in the limiting groove 9. One end of the rod is welded and fixed to the tool holder, and the other end is inserted into the limiting groove 9 and tightly fitted to the groove wall to limit the sway of the tool holder.

[0029] Actual work process:

[0030] The hydraulic telescopic rod 7 is in the retracted state, and the cutting knife 3 is located directly above the guide slot 4 and is not in contact with the guide slot 4; the scraper 13 of the elastic scraping assembly 11 is kept in a naturally open state under the action of the angle spring.

[0031] When the concrete is initially formed in the slipform mold 2 and moves to the tail, and when it needs to be cut, the hydraulic telescopic rod 7 and the vibrator are activated.

[0032] The hydraulic telescopic rod 7 extends, pushing the cutter holder to move the cutting blade 3 downwards. The cutting blade 3 first contacts the guide slot 4, where the shallow grooves on both sides compress the inverted V-shaped tip of the scraper 13, causing the scraper 13 to rotate around the hinge axis and compress the angle spring, allowing the cutting blade 3 to smoothly pass through the guide slot 4. It then passes through the mold ventilation gap 5 and, under the high-frequency vibration of the vibrator, inserts into the formed concrete structure 6, completing the cut to the predetermined depth. During this process, the limiting rod 10 slides synchronously along the limiting groove 9 to ensure the perpendicularity of the cutting blade 3; the shallow grooves guide the flow of concrete slurry, reducing viscous resistance.

[0033] After the cutting is completed, the hydraulic telescopic rod 7 retracts, pulling the cutting blade 3 upward. At this time, the spring force keeps the scraping end of the scraper 13 in contact with the inner wall of the shallow groove, scraping away the residual concrete slurry and preventing the slurry from solidifying and affecting the next use. After the cutting blade 3 is completely disengaged from the guide slot 4, the device returns to its initial state and waits for the next cutting command.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
