Therefore, various innovative architectural finishing techniques are emerging, such as specific textured effects like surface roughening and imitation stone textures, to enhance the texture and layering of buildings. Another approach involves artistic sculpting patterns: achieving complex, specified pre-designed patterns, logos, or geometric shapes, making the building's exterior a unique artistic medium. Currently, this mainly relies on construction workers using hand tools such as electric hammers and pneumatic drills for manual operation. Summary of the Invention

The push block has arc-shaped guide surfaces on both sides of the sliding direction of the T-shaped connection. The inner side of the support guide rail is provided with multiple retaining grooves. The shape of the multiple retaining grooves matches the shape of the push block. The push block is configured to retractably engage with the multiple retaining grooves.

Detailed Implementation

[0016] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0017] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0018] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides an artistic carving concrete construction machine for processing concrete walls, including: a fixed base 100, a frame arm 200, a movable base 300, and a carving device 400. The fixed base 100 serves as the foundation for the entire machine's load-bearing and positioning. A first drive device 110, rotatable around its central axis, is located in its central area. The bottom of the fixed base 100 features a weighted, anti-slip design to ensure the machine's stability during operation. The first end 210 of the frame arm 200 is rigidly connected to the first drive device 110, with a rotating sealing sleeve at the connection point to prevent dust from entering the drive mechanism. The frame arm 200 can rotate smoothly around the central axis of the fixed base 100 under the drive of the first drive device 110. The movable base 300 is slidably mounted on the frame arm 200 via a guide structure and is equipped with a dedicated drive mechanism, allowing controlled linear sliding along the length of the frame arm 200. The carving device 400 is detachably mounted on the side of the movable base 300 facing the wall, with its working end aligned with the wall. Through the above-mentioned structural linkage, the controlled rotation of the frame arm 200 and the controlled sliding of the moving seat 300 enable the carving device 400 to move flexibly within a fan-shaped area centered on the central axis of the fixed base 100 and complete the carving operation.

[0019] The first drive device 110 can adopt a combination structure of servo motor and reducer. The servo motor and reducer are connected by a rigid coupling. The servo motor can receive commands from the control system to control the torque and speed, thereby adjusting the angle of the frame arm 200. The core function of the reducer is to amplify the output torque of the servo motor to ensure that it is sufficient to drive the overall load of the frame arm 200, the moving seat 300 and the carving device 400. At the same time, in conjunction with the electromagnetic brake function built into the servo motor, the angle positioning and stopping of the frame arm 200 can be achieved.

[0020] The movable seat 300 can achieve radial sliding using a ball screw transmission mechanism driven by a servo motor. Specifically, the ball screw is arranged horizontally along the length of the frame arm 200, and its two ends are fixed by bearing seats to ensure no radial runout during rotation. The movable seat 300 is rigidly connected to the nut seat of the ball screw, and the two sides of the movable seat 300 are slidably engaged with linear guide rails on the frame arm 200 through sliders. The linear guide rails provide guidance and limit for the movable seat 300. When the servo motor drives the ball screw to rotate, the nut seat converts the rotational motion into linear motion, thereby driving the movable seat 300 to perform high-precision linear sliding along the frame arm 200, achieving radial position control.

[0021] Firstly, this application utilizes a system that automatically controls the rotation angle of the frame arm 200 and the radial position of the moving seat 300 by receiving digital pattern commands, thereby driving the carving device 400 to complete the work. This frees the operator from heavy physical labor and dusty environments, improves efficiency, and eliminates hand tremors and fatigue errors associated with manual operation.

[0022] Secondly, the rotational motion of the construction machine around its central axis and its radial linear motion constitute a polar coordinate (or sector) working area. Many artistic patterns, such as sun rays, concentric circles, spirals, and sector divisions, are mathematically best defined and described using polar coordinates (radius R, angle θ). The movement of this equipment is consistent with the generation logic of such patterns. The control software can directly and efficiently convert design data into motion commands, making path planning extremely simple and direct, and the processed curves or radial lines are natural and smooth.

[0023] Furthermore, the fixed base 100 supporting rotation and the radial frame arm mechanism of this application reduce the space occupied on the construction site compared to large gantry cranes. The fixed base 100 can be equipped with retractable casters at its bottom. When the construction machine needs to be moved, the casters extend to lift the entire machine off the ground, making it easy for operators to push the equipment to the designated construction position. Once in position, the casters are retracted, allowing the anti-slip structure at the bottom of the fixed base 100 to directly contact the ground, achieving stable fixation using the machine's own weight. This ensures the stability of subsequent carving operations, making it particularly suitable for construction needs in narrow spaces such as indoor corridors and elevator lobbies.

[0024] Combination Figure 4 In one embodiment, a linear drive device 500 is provided between the movable base 300 and the carving device 400. The linear drive device 500 is used to drive the carving device 400 to move linearly along the impact direction parallel to the carving device 400, so as to adjust the relative distance between the working end of the carving device 400 and the wall, and realize the controllable adjustment of the carving depth.

[0025] The linear drive device 500 can be a miniature electric actuator, powered by an independent battery module and with an independent controller responding to depth movement commands. In this embodiment, the device precisely controls the planar positioning of the carving head on the wall surface through the rotation of the frame arm 200 and the sliding of the moving base 300. The introduction of the linear drive device 500 adds an independent control dimension to the cutting depth of the carving head. This allows the device to not only carve the outline of the pattern according to a preset digital model, but also precisely control the depth processing requirements of different positions within the pattern.

[0026] refer to Figure 7 and Figure 8 In one embodiment, the working end of the carving device 400 is detachably connected to a carving component 410. The carving component 410 includes a working surface with multiple mounting holes 411, and multiple carving heads are threadedly connected to the mounting holes 411. The working end of the carving device 400 can be connected to the carving component 410 via quick-release clips, bolts, or other means. The working surface of the carving component 410 has multiple standardized mounting holes 411, and each carving head is independently fixed by a threaded connection. Carving heads are vulnerable parts that directly impact concrete, and wear, chipping, and even breakage are common failures. This embodiment allows the operator to remove only the damaged individual carving head. By replacing carving heads of different specifications, such as diameter, shape, and material, or by adjusting the combination and layout of different carving heads on the same carving component 410, drastically different carving textures and surface effects can be produced directly without replacing the main unit.

[0027] In one embodiment, the carving component 410 includes a worktable 413 and a collection hood 414; the work surface is configured such that the worktable 413 faces the wall, and the collection hood 414 covers the periphery of the worktable 413 and is installed on the side of the worktable 413 facing away from the work surface, forming a collection cavity. Concrete carving generates a large amount of dust, and the collection hood 414 can capture and confine most of the dust within the collection cavity at the initial stage of dust diffusion, greatly reducing dust dispersion at the construction site.

[0028] refer to Figure 1 , Figure 5 and Figure 6 In one embodiment, the art carving concrete construction machine further includes an arc-shaped support frame 600, the two ends of which are connected to the fixed base 100, and the extension trajectory of the arc-shaped support frame 600 is consistent with the rotation trajectory of the frame arm 200; the arc-shaped support frame 600 is provided with a support guide rail 610 facing the frame arm 200 and extending along the rotation trajectory of the frame arm 200; a T-shaped connecting part is fixed on the back of the frame arm 200, the cross-sectional shape of the T-shaped connecting part is adapted to the cross-sectional shape of the support guide rail 610, and the T-shaped connecting part is slidably engaged with the arc-shaped support guide rail 610.

[0029] In this embodiment, the extended trajectory is aligned with the rotation trajectory of the frame arm 200, sharing the same center and arc. This ensures that the T-shaped connection always fits snugly against the support guide rail 610, eliminating the risk of detachment or jamming. The T-shaped connection's cross-section is adapted to the support guide rail 610, limiting the radial offset of the frame arm 200 without affecting its smooth rotation along the arc trajectory. Both ends of the support frame are fixed to the fixed base 100, forming a triangular stable structure of the fixed base 100, the arc-shaped support frame 600, and the frame arm 200. This transforms the cantilever force of the frame arm 200 into a two-point support force, distributing the load. This further improves the stability of the frame arm 200 during processing.

[0030] In one embodiment, a receiving groove 221 is provided on the T-shaped connecting part along the radial direction of the arc-shaped support guide rail 610. An elastic member and a push block 223 are installed in the receiving groove 221. The elastic member acts on the push block 223, so that the push block 223 can extend out of the receiving groove 221 along the radial direction of the arc-shaped support guide rail 610. The push block 223 has arc-shaped guide surfaces on both sides in the sliding direction of the T-shaped connecting part. A plurality of retaining grooves 620 are provided on the inner side of the support guide rail 610. The shape of the plurality of retaining grooves 620 matches the shape of the push block 223. The push block 223 is configured to retractably engage with the plurality of retaining grooves 620. The push block 223 cooperates with the plurality of retaining grooves 620 to limit the frame arm 200 when it is rotated to a designated position.

[0031] When there is no driving force, the elastic element, which can be a compression spring, can be adjusted as needed and is always in a pre-compressed state, pushing the push block 223 radially out of the receiving groove 221. When the frame arm 200 rotates to the point where the push block 223 is aligned with any stop groove 620, the push block 223 is instantly engaged in the stop groove 620 under the action of the elastic force, limiting the sliding of the T-shaped connection part through mechanical engagement, thereby locking the angle of the frame arm 200. When there is a driving force, that is, when the frame arm 200 is subjected to the rotational torque of the first driving device 110, the inner wall of the stop groove 620 contacts the arc-shaped guide surface of the push block 223, generating a separation that overcomes the elastic force of the elastic element, pushing the push block 223 radially retracting into the receiving groove 221, releasing the limit, and the frame arm 200 can continue to rotate to the next target angle. Multiple stop grooves 620 are evenly distributed along the inner side of the arc-shaped support guide rail 610, which can cover the rotation range of the frame arm 200 and ensure that the key processing angles can be limited.

[0032] In one embodiment, the fixed base 100 is equipped with an air source device 700, and the movable base 300 is provided with an air outlet 310 facing the wall. The air source device 700 is connected to the air outlet 310 through a ventilation pipe 710. The frame arm 200 has a wiring cavity 230 inside, and the ventilation pipe 710 is accommodated in the wiring cavity 230. The air source device 700 delivers compressed air to the air outlet 310 through the ventilation pipe 710. The air outlet 310 forms an airflow beam, which blows towards the carving work point, promptly dispersing the newly generated concrete dust and reducing dust from getting stuck inside the movable base 300. Combined with the setting of the collection cover 414, most of the dust is collected or dispersed, ensuring that the area around the carving device 400 is in a dust-free working environment.

[0033] The ventilation duct 710 can be made of polyurethane flexible hose, with a 20%~30% expansion allowance. This means the actual length equals the sum of the maximum rotation radius of the frame arm 200, the maximum sliding stroke of the moving base 300, and the allowance. The air source device 700 can be a small oil-free air compressor, fixed to the fixed base 100, equipped with a pressure regulating valve to adjust the airflow intensity as needed. The wiring cavity 230 is pre-installed inside the frame arm 200, with a rectangular cross-section, its dimensions adapted to the duct and cable compartments. Wear-resistant rubber pads can be attached to the inner wall to reduce frictional loss during the movement of the ventilation duct 710.

[0034] Combination Figure 8 , Figure 9 , Figure 10 and Figure 11 In another embodiment, the airflow coverage of the aforementioned vent 310 is directed towards the entire carving device 400, primarily used to blow away dust dispersed after a period of carving work. However, dust accumulation on the worktable 413 surface of the carving piece 410 remains a problem, especially in vertical carving scenarios such as carving ceilings. The dust accumulated on the worktable 413 surface gradually thickens as the work progresses. If the accumulation height exceeds the extension length of the carving head 412, it will directly hinder the contact between the carving head 412 and the concrete wall, affecting the carving accuracy and effect.

[0035] Based on this, in this embodiment, a dust guide is installed inside the workbench 413. Slots are respectively formed on opposite sides of the workbench 413, with the openings facing outwards, i.e., the two opposite sides adjacent to the work surface. Simultaneously, two elongated holes perpendicularly penetrating the thickness direction are also formed on the workbench 413. These two elongated holes correspond one-to-one with the two slots and are interconnected. The length and width of the elongated holes are adapted to the subsequent installation requirements of the dust guide. This embodiment configures two detachable dust guides 800, which are respectively installed in the two slots of the workbench 413; each dust guide 800 includes a body 810, an elongated through-hole 820, and a battery assembly 830.

[0036] The body 810's shape matches the shape and size of the slot, allowing for quick installation or removal by pushing and pulling along the slot direction. A long through hole 820 is located in the center of the body 810, its length and width matching the elongated hole on the worktable 413. When the body 810 is fully embedded in the slot, the long through hole 820 aligns with the elongated hole on the worktable 413, forming a dust guide channel that runs through the worktable 413. The battery assembly 830 is built into a non-through area of ​​the body 810, providing independent power support for dust guidance without requiring an external power source.

[0037] The two opposing inner sidewalls of the elongated through-hole 820 are defined as a first sidewall 821 and a second sidewall 822, respectively. A first guide plate 831 is provided at the end of the first sidewall 821 closest to the working surface of the worktable 413, and a second guide plate 832 is provided at the end of the second sidewall 822 furthest from the working surface of the worktable 413. Both the first guide plate 831 and the second guide plate 832 are electrically connected to the battery assembly 830, and are respectively connected to the positive and negative terminals of the battery, forming a downward-sloping electric field. The direction of the electric field is from the first guide plate 831 to the second guide plate 832, penetrating the flow channel of the elongated through-hole 820.

[0038] Two elongated holes each correspond to a set of dust guides 800, and the battery components 830 of the two dust guides 800 are wired in opposite directions, resulting in different electric field directions within the two elongated holes 820. During concrete carving, dust generates static electricity due to friction and impact, and dust particles may carry positive or negative charges. When charged dust falls onto the surface of the workbench 413, it is subjected to an electric field force in the corresponding direction, passing through the elongated hole 820 along the electric field direction and finally falling into the collection cover 414 on the back of the workbench 413. By coordinating two electric fields in different directions, positive and negative charged dust can be guided, completely preventing dust accumulation on the work surface of the workbench 413 and ensuring operational stability in special scenarios such as vertical carving. A pull ring can also be installed on the outside of the dust guide 800 for easy removal from the slot. This application also provides a control method for an art carving concrete construction machine, which uses any of the above-mentioned art carving concrete construction machines to carve patterns on a concrete wall, including: acquiring pattern data of a preset pattern; determining the coordinates of multiple target points in a polar coordinate system based on the pattern data, the coordinates including angular coordinate values ​​and radial distance coordinate values ​​with the central axis of the fixed base 100 as the origin; driving the first drive device 110 to rotate the frame arm 200 to the corresponding angle based on the angular coordinate values ​​of the target points; driving the movable seat 300 to slide along the frame arm 200 to the corresponding radial position based on the radial distance coordinate values ​​of the target points; and controlling the carving device 400 to start the carving operation.

[0039] The system acquires pattern data for a preset pattern by importing a 2D pattern file. The pattern processing module within the control system converts the pattern's line information into coordinate values ​​in a polar coordinate system, including angular coordinates (the angle between the line connecting the node and the origin and the reference axis, such as horizontal to the right) and radial distance coordinates (the straight-line distance from the node to the origin). Multiple target points are then path-planned, for example, by arranging the processing sequence according to the increasing / decreasing angle of the target points. The control system then sends pulse signals to the first drive device 110 to precisely control the motor's rotation angle. After the motor drives the frame arm 200 to rotate to the target angle, the electromagnetic brake locks, and simultaneously, the mechanical limit push block 223 engages with the corresponding stop groove 620, achieving dual positioning. Simultaneously, a signal is sent to the servo motor of the moving seat 300, driving the moving seat 300 to slide along the frame arm 200 to the target radial position. Once the frame arm 200 and the moving seat 300 reach the target position and stabilize, the control system sends a start signal to the carving device 400. After processing a single target point, the carving device 400 automatically shuts down, and the drive mechanism moves to the next target point, repeating the cycle.

[0040] In one embodiment, the artistic sculpting concrete construction machine includes: a linear drive device 500 disposed between a movable base 300 and a sculpting device 400, the linear drive device 500 being used to drive the sculpting device 400 to move linearly along a direction parallel to the impact direction of the sculpting device 400, thereby adjusting the relative distance between the working end of the sculpting device 400 and the wall; the control method further includes: acquiring pattern data of a preset pattern; determining the coordinates of multiple target points in a polar coordinate system based on the pattern data, the coordinates further including: the depth coordinate value of the target point relative to a preset reference plane in the wall normal direction. Based on the depth coordinate value of the target point, the linear drive device 500 is driven to adjust the working end of the sculpting device 400 to a position corresponding to the depth coordinate value.

[0041] Pattern data for a preset pattern can be obtained by importing a 3D file, using the wall surface as a preset reference plane, to obtain the depth coordinates of multiple target points in the 3D file. Depth processing planning can be layered according to depth values, processing sequentially from shallow to deep or from deep to shallow.

[0042] After the first drive device 110 rotates the frame arm 200 to the angular coordinate value, and the servo motor drives the moving seat 300 to slide to the radial distance coordinate value, the linear drive device 500 pushes the carving device 400 forward or backward to the depth coordinate value. The three components complete the positioning, ensuring the three-dimensional coordinates of the target point are matched. Then, the carving device 400 is activated to begin operation. This embodiment enables the artistic carving concrete construction machine not only to perform planar processing but also to meet higher artistic creation needs, providing richer and more refined solutions for concrete wall decoration.

[0043] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
