Description

Technical Field

[0001] This invention relates to the field of precast concrete component cutting technology, specifically to a precast concrete component cutting device for building construction. Background Technology

[0002] With the rapid development of the prefabricated building industry, precast concrete components, as the core components of prefabricated buildings, directly affect the quality of prefabricated buildings. However, precast concrete components need to be cut during actual processing. For example, patent CN221912705U discloses a concrete component cutting device, including an operating table, a gantry frame, a cylinder assembly, a cutting mechanism, and a pushing mechanism. The gantry frame is located on the top side of the operating table, the cylinder assembly is installed through the top of the gantry frame, a support frame is located in the middle of the gantry frame, and the cutting mechanism is located in the bottom middle of the support frame. The cutting mechanism is used for cutting concrete components. The top of the support frame is connected to the output end of the cylinder assembly, and the pushing mechanism is located on the top side of the operating table away from the gantry frame. This device can reduce the impact of dust during concrete component cutting and effectively improve the cutting efficiency of concrete components. For example, patent CN216400136U discloses a concrete component cutting device, including a worktable. The upper surface of the worktable has a storage groove, and a grid mesh is overlapped inside the storage groove. Slide rods are fixedly connected to both the front and back of the worktable. A U-shaped bracket is slidably connected to the outer surface of the slide rod. A groove is formed in the inner top wall of the U-shaped bracket. An adjusting screw is rotatably connected to the inner front and rear walls of the groove. An adjusting block is threaded onto the outer surface of the adjusting screw, and an electric telescopic rod is fixedly connected to the lower surface of the adjusting block. This device facilitates the movement of the U-shaped bracket, making it easy to adjust the position of the cutting blade, thus facilitating the cutting of concrete components. It also avoids the emission of large amounts of dust during cutting, providing a good dust reduction effect. However, considering the current practical use of concrete component cutting devices, they still have certain drawbacks, such as: 1. The component conveying and positioning structure is simple and can only realize the straight pushing of the foundation. It cannot be adapted to the precise positioning of precast concrete components of different sizes and irregular cross sections. During the cutting process, the components are prone to displacement, resulting in insufficient cutting accuracy, chipping of the cut edge and other problems, which affect the flatness of the cut and the cutting accuracy. 2. The cutting mechanism has limited degrees of freedom, the adjustment process is cumbersome, and it cannot achieve multi-degree-of-freedom linkage adjustment, making it difficult to meet the complex processing requirements such as oblique cutting and irregular contour cutting of concrete components. 3. There is no dedicated and adaptable feeding mechanism. For heavy and large-sized precast concrete components, manual feeding is difficult and has high safety risks. It is also easy to cause damage to the edges and corners of the components. It cannot be adapted to feeding stations of different heights. Therefore, we propose a precast concrete component cutting device for building construction to solve the problems mentioned above. Summary of the Invention

The top frame is lifted and connected above the base frame. The slide rail is vertically fixed to the inner wall of the top frame. The lifting frame is slidably connected to the top frame via the slide rail. A third adjusting rod is rotatably installed inside the lifting frame. The slide table is slidably installed inside the lifting frame via the third adjusting rod. The bottom of the slide table is connected to the mounting box. The cutting element is fixedly installed at the bottom of the mounting box.

[0010] Furthermore: a second telescopic rod is symmetrically and vertically fixed on the top side of the base frame, and the top frame is fixed to the top of the telescopic end of the second telescopic rod.

[0011] Furthermore: one end of the mounting box is rotatably mounted on the bottom surface of the slide via a pivot, and the other end of the mounting box is connected to the slide via a third telescopic rod, with the two ends of the third telescopic rod being hinged to the slide and the mounting box, respectively.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Please see Figures 1-11 The present invention provides the following technical solution: A precast concrete component cutting device for building construction includes: a base 1, a platform 2, a partition 3, a fixed wheel 4, a carrier plate 5, a connecting frame 6, a drive wheel 7, a slider 8, a sliding rod 9, a support plate 10, a fixed frame 11, a first telescopic rod 12, a top head 13, a rotating motor 14, a mounting frame 15, a pressure plate 16, a first adjusting rod 17, a pressure pad 18, a second adjusting rod 19, a base frame 20, a top frame 21, a second telescopic rod 22, a lifting frame 23, a slide rail 24, a third adjusting rod 25, a slide table 26, a mounting box 27, a third telescopic rod 28, a cutting element 29, a water pipe 30, a partition net 31, an outer side plate 32, an inner side plate 33, a conveying roller 34, a chute 35, a cross brace 36, a clamp 37, a limiting plate 38, a telescopic frame 39, a mounting seat 40, a telescopic roller 41, and a feeding belt 42. Wherein: the table plate 2 is fixedly installed on the top of the base 1, the partition 3 is vertically fixed on the side of the table plate 2, the partition 3 divides the upper surface of the table plate 2 into a conveying operation area and a cutting operation area, and the bottom of the base 1 can be equipped with lockable casters and leveling feet. In a specific application scenario: a conveying positioning mechanism is installed in the conveying operation area located on the side of the table 2. This conveying positioning mechanism is symmetrically arranged on both sides of the cutting operation area and includes fixed wheels 4, a carrier plate 5, a connecting frame 6, a drive wheel 7, a slider 8, a sliding rod 9, and a support plate 10. Two sets of sliding rods 9 are provided, and the two sets of sliding rods 9 are fixed parallel to each other on the upper surface of the table 2. The axis of the sliding rods 9 is parallel to the center line of the partition plate 3 to ensure that the component conveying direction is accurately aligned with the cutting station. The slider 8 is arranged one-to-one with the sliding rod 9. The slider 8 is slidably connected to the top of the sliding rod 9. One side of the bottom surface of the carrier plate 5 is flush with the slider 8. The platform 5 is fixed in one piece. The upper surface of the platform 5 is provided with anti-slip texture to support the precast concrete components to be cut and prevent the components from slipping when placed. The support plate 10 is fixed to the bottom of the slide rod 9 to support and fix the slide rod 9 on the platform 2. The connecting frame 6 is fixed on the outer side of the bottom surface of the platform 5. The drive wheel 7 is rotatably installed on the inner side of the connecting frame 6 through the rotating shaft. The fixed wheel 4 is fixedly installed between the partitions 3 set on the upper side of the platform 2, and the wheel surface of the fixed wheel 4 meshes with the wheel surface of the drive wheel 7 for transmission. The fixed wheels 4 are set at equal intervals. The rotation of the drive wheel 7 drives the platform 5 to slide while supporting the concrete components.

[0018] The above technical solution utilizes a conveying structure where the drive wheel 7 meshes with the fixed wheel 4, replacing the traditional push-type conveying mode. This enables high-precision linear motion of the carrier plate 5, accurately controlling the feed amount and cutting positioning accuracy of the precast concrete components, and avoiding problems such as skewed cuts and insufficient precision caused by component conveying deviation. The guide support structure of the double slide bar 9 and the slider 8 significantly improves the operational stability of the carrier plate 5 when carrying heavy components, eliminating swaying and tilting problems during conveying. In conjunction with the anti-slip texture on the surface of the carrier plate 5, the static friction with the components is enhanced, further ensuring the positional stability of the components during conveying, and adapting to continuous conveying operations of precast concrete components of different weights and sizes.

[0019] In specific application scenarios: the upper surface of the carrier plate 5 is equipped with a multi-dimensional limiting mechanism, including a lateral limiting component and a top limiting component, to achieve multi-degree-of-freedom locking of the precast concrete component. The lateral limiting component includes a fixing frame 11, a first telescopic rod 12, and a top head 13. The fixing frame 11 is fixed to the outer edge of the upper surface of the carrier plate 5. The first telescopic rod 12 is horizontally installed inside the fixing frame 11, and the telescopic end of the first telescopic rod 12 faces the inner edge of the carrier plate 5. The top head 13 is fixed to the telescopic end of the first telescopic rod 12. The top head 13 adopts an arc-shaped structure made of rubber to increase the contact area with the side of the precast concrete component. The top limiting component includes a rotating motor 14, a mounting frame 15, and a pressure... The mounting plate 16, the first adjusting rod 17, and the pressure pad 18 are included. The rotating motor 14 is fixed to the inner middle of the fixing frame 11. The mounting frame 15 has an L-shaped structure. The bottom end of the vertical section of the mounting frame 15 is fixedly connected to the output shaft of the rotating motor 14. The rotating motor 14 can drive the mounting frame 15 to rotate 90° in the vertical plane to realize the switching between opening and closing and pressing of the pressure plate 16. The end of the pressure plate 16 is slidably connected to the through groove opened inside the mounting frame 15. The outer side of its end face is threadedly connected to the first adjusting rod 17. The first adjusting rod 17 is rotatably installed on the outside of the mounting frame 15 to realize the lifting and lowering adjustment of the pressure plate 16. The pressure pad 18 is fixedly bonded to the lower surface of the pressure plate 16. The pressure pad 18 is made of polyurethane wear-resistant pad.

[0020] The above technical solution employs a multi-dimensional limiting structure that combines lateral clamping and top pressing. This structure simultaneously locks the horizontal and vertical degrees of freedom of the precast concrete component, completely preventing vibration and displacement during cutting, effectively preventing chipping and insufficient flatness, and significantly improving cutting quality. The lateral limiting component uses a rubber arc-shaped top head 13, which can adapt to precast concrete components of different widths and cross-sectional shapes. The arc-shaped contact surface increases the clamping and contact area, preventing stress concentration and damage to the component surface, thus balancing clamping stability and component protection. The top limiting component uses a flip-up mounting bracket 15 with a threaded lifting and adjusting pressure plate 16. When loading components, the bracket can be flipped open to completely avoid interference with the loading space. During operation, the bracket can be quickly flipped and pressed. The pressing height and clamping force are precisely controlled by the first adjusting rod 17. Combined with the polyurethane wear-resistant pressure pad 18, this ensures both pressing tightness and adaptability to precast concrete components with uneven surfaces, thus broadening the application range.

[0021] In a specific application scenario: A multi-degree-of-freedom cutting mechanism is installed above the cutting work area on the surface of the table 2. This mechanism includes a second adjusting rod 19, a base frame 20, a top frame 21, a second telescopic rod 22, a lifting frame 23, a slide rail 24, a third adjusting rod 25, a slide table 26, a mounting box 27, a third telescopic rod 28, and a cutting element 29. The second adjusting rod 19 is symmetrically rotated and arranged on the side of the base 1. The base frame 20 is slidably mounted on the upper surface of the table 2. The bottom end of the base frame 20 is connected to the outside of the second adjusting rod 19 to drive its sliding. The sliding direction of the base frame 20 is the same as the moving direction of the carrier plate 5, enabling coarse adjustment of the front and rear positions of the cutting mechanism. The second telescopic rod 22 is vertically fixed to the side of the base frame 20, and the top frame 21 is fixed to the top of the telescopic end of the second telescopic rod 22. The extension and retraction of the telescopic rod 22 can drive the top frame 21 to move vertically up and down above the base frame 20, thereby achieving coarse adjustment of the cutting height. The slide rail 24 is vertically fixed to the inner wall of the top frame 21. The lifting frame 23 is slidably connected to the top frame 21 through the slide rail 24. The third adjusting rod 25 is longitudinally rotatably installed inside the lifting frame 23. The slide table 26 is slidably installed inside the lifting frame 23 through the third adjusting rod 25. The mounting box 27 is rotatably installed on one side of the bottom surface of the slide table 26 through a rotating shaft. The other side of the bottom surface of the slide table 26 is provided with a third telescopic rod 28. The upper and lower ends of the third telescopic rod 28 are respectively connected to the end faces of the slide table 26 and the mounting box 27. The cutting element 29 is fixed to the bottom of the mounting box 27. The cutting element 29 includes a cutting motor and a diamond cutting saw blade, and is used for cutting concrete components.

[0022] By adopting the above technical solution, through the multi-degree-of-freedom linkage adjustment structure of the base frame 20 for lateral feed, the top frame 21 for lifting and coarse adjustment, the lifting frame 23 for lifting and adjustment, the slide table 26 for longitudinal feed, and the mounting box 27 for angular swing, the cutting element 29 can be adjusted in all positions (front and back, up and down, left and right) as well as the cutting angle can be adjusted steplessly. It can not only complete conventional vertical straight cutting operations, but also adapt to complex processing needs such as oblique cutting and irregular contour cutting, completely solving the problems of insufficient freedom and poor adaptability of traditional cutting mechanisms.

[0023] In a specific application scenario: A water pipe 30 is fixed above the top frame 21. The water outlet of the water pipe 30 faces the cutting position of the cutting saw blade of the cutting element 29. The water inlet of the water pipe 30 is connected to the water supply system or the bottom of the base 1 through a high-pressure hose. The base 1 is equipped with a mesh 31. During the cutting process, through the hollow structure of the table plate 2, the impurities are flushed by the water flow and fall directly into the interior of the base 1. The wastewater is filtered by the mesh 31 and discharged. It is then returned to the water pipe 30 for dust suppression and reuse. Concrete debris and impurities are retained on the mesh 31 for easy cleaning and recycling.

[0024] The above technical solution involves directly aligning the water outlet of the water pipe 30 with the working position of the cutting element 29, enabling simultaneous high-pressure spraying to suppress dust during cutting operations. This inhibits the spread of cutting dust at the source and simultaneously cools the high-speed cutting saw blade in real time, effectively reducing thermal wear and extending the service life of the cutting element 29. The matching hollow structure of the table plate 2 and the solid-liquid separation structure with the built-in mesh 31 in the base 1 allow wastewater and concrete debris generated during cutting to fall directly into the base 1 via water flow. Solid-liquid separation is achieved through the mesh 31, with solid debris remaining on its surface for easy cleaning. The filtered wastewater can be recycled back to the spraying system, reducing wastewater discharge at the construction site and lowering water consumption, significantly improving environmental friendliness and practicality.

[0025] In a specific application scenario: An adjustable feeding mechanism is provided at the left feeding end of the base 1, corresponding to the carrier plate 5. This mechanism includes an outer side plate 32, an inner side plate 33, a conveyor roller 34, a chute 35, a cross brace 36, a clamp 37, a limiting plate 38, a telescopic frame 39, a mounting base 40, a telescopic roller 41, and a feeding belt 42. Two sets of outer side plates 32 and inner side plates 33 are symmetrically arranged. The conveyor roller 34 is rotatably mounted at the ends of the outer side plates 32 and inner side plates 33. A chute 35 is provided between each set of outer side plates 32 and inner side plates 33. Clamps 37 are fixed to both ends of the cross brace 36, and the clamps 37 are inserted into the inner side of the chute 35, corresponding to the outer side plate 32. After the relative length of the inner side plate 33 is adjusted, the two sections of the limit plate 38 and the clamp 37 are aligned, and the whip bolt of the clamp 37 is fixed with a nut. This fixes the cross brace 36, the limit plate 38, the outer side plate 32 and the inner side plate 33, thereby fixing the distance between the end conveying rollers 34 of the outer side plate 32 and the inner side plate 33. The arrangement angle of the feeding belt 42 is adjusted by adjusting the distance. The telescopic frame 39 is fixed to the bottom surface of the cross brace 36, the mounting base 40 is fixed to the telescopic end of the telescopic frame 39, the telescopic roller 41 is rotatably mounted on the outside of the mounting base 40, and the feeding belt 42 is wrapped around the outside of the conveying roller 34 and the telescopic roller 41.

[0026] The above technical solution allows for rapid adjustment of the distance between the two sets of conveying rollers 34 through the sliding adjustable outer plate 32 and inner plate 33 combined with the lockable cross brace 36, adapting to precast concrete components of different sizes. After adjustment, the components can be quickly locked and fixed by the clamp 37 and the limiting plate 38. The structure is simple, the adjustment is convenient, and the versatility of the device is greatly improved. The telescopic frame 39 drives the telescopic roller 41 to extend and retract, which can flexibly adjust the inclination angle of the feeding belt 42 to adapt to different feeding requirements on site. At the same time, it can ensure that the feeding belt 42 is always in a stable tension state, avoiding slippage and jamming during the feeding process. For heavy and large-sized precast concrete components, it can achieve stable and automated feeding, greatly reducing the labor intensity and safety risks of manual feeding.

[0027] When using the device, move it to the work station and level and lock it. According to the size of the precast concrete component to be cut and the cutting process requirements, adjust the appropriate width and feeding angle of the feeding mechanism, and the cutting position, angle and depth of the cutting mechanism. Connect the device power supply and spray water circuit, and check the operating status of each drive component. Place the precast concrete component to be cut on the feeding belt 42, start the conveyor roller 34 to drive the feeding belt 42 to run, and smoothly transport the component to the designated bearing position of the carrier plate 5 to complete the automated feeding; Start the first telescopic rods 12 on both sides to extend synchronously, clamp the two sides of the component through the top head 13, and complete the lateral limit locking; start the rotating motor 14 to drive the mounting frame 15 to flip, so that the pressure plate 16 moves to the top of the component, rotate the first adjusting rod 17 to drive the pressure plate 16 to descend, press and fix the top of the component, and complete the full degree of freedom limit of the component to avoid displacement vibration during cutting; Start the drive wheel 7, and through the meshing transmission between the drive wheel 7 and the fixed wheel 4, drive the carrier plate 5 to move in a high-precision linear motion along the slide bar 9, accurately transporting the part of the component to be cut to the working position of the cutting element 29, and locking the conveying mechanism after it is in place. The cutting motor of the cutting element 29 is started, driving the diamond saw blade to rotate at high speed. At the same time, the water valve is opened, and high-pressure water is sprayed onto the cutting position to reduce dust and cool the saw blade. By adjusting the feed of the slide table 26 and the angle of the mounting box 27, the straight / oblique / irregular cutting of the component is completed. The wastewater and debris generated by cutting fall into the base 1 through the hollow structure of the table plate 2. Solid-liquid separation is completed through the partition 31. The wastewater can be recycled and sprayed for use, while the debris is left to be cleaned. After cutting is completed, the cutting motor and water circuit are turned off, the cutting element 29 retracts and resets, and the carrier plate 5 moves in the opposite direction back to the initial feeding position; the top pressure plate 16 and the side top head 13 are released in sequence to release the component limit, and the cutting component is smoothly output through the reverse operation of the feeding mechanism to complete the unloading.
