Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a concrete finishing construction component. BACKGROUND

[0002] In the process of large-scale industrial floor construction, such as large warehouses, logistics centers and commercial halls, the flatness, compactness and long-term structural stability of the concrete floor are extremely demanding.

[0003] The current industry generally uses large concrete finishing construction devices for work, for example, Chinese patent CN117846268B discloses a building construction concrete floor finishing device, Chinese patent CN120311940A discloses a building construction concrete floor finishing device, etc. These devices can achieve efficient and uniform finishing effect when dealing with open and unobstructed areas, significantly improving construction quality.

[0004] However, when the construction area extends to the vicinity of vertical obstacles, such as the edge of a building wall, a support column or a pre-embedded equipment base, etc., the rigid structure design and fixed geometry of the existing device expose obvious deficiencies. The working components cannot be flexibly adjusted to fit the complex profile of the obstacle, resulting in the formation of an annular "dead zone" on the concrete surface in the boundary area. This area often has uneven surface, honeycomb holes and pitted surface defects, which seriously affect the overall strength and durability of the concrete. To make up for this defect, the construction team has to interrupt the automated process and rely on manual tools for secondary smoothing operation or local repair. This additional manual intervention not only significantly reduces the degree of automation and continuity of the construction process, but also significantly prolongs the project cycle, increases labor input and management costs.

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0018] In large industrial floor construction, such as large warehouses, logistics centers or commercial halls, etc., the flatness, compactness and durability of the concrete floor are of the highest requirements. The existing large concrete finishing construction device performs well in handling wide and open areas, but it has inherent limitations when it is close to vertical obstacles such as walls, columns or embedded equipment. This geometry cannot accurately process the concrete surface to the edge of the obstacle, resulting in a "dead zone" or unfinished perimeter in these boundary areas. In order to complete the construction of these areas, it is usually necessary to rely on manual secondary troweling or use small auxiliary tools, which significantly reduces the degree of automation and efficiency of the overall construction, increases labor costs and project cycle.

[0019] To this end, the application provides a concrete finishing construction component, which is installed on a main frame. The main frame can be a concrete finishing construction device mentioned in the prior art, or a walking trolley with a traveling mechanism. The component includes a mounting rack 100, which includes a bottom plate 101 and a side plate 102 on each side of the bottom plate 101. The two side plates 102 extend to one side of the bottom plate 101 to form a suspended end, and the suspended ends of the two side plates 102 and the bottom plate 101 form a U-shaped slot S1. A flexible troweling plate 200 is rotatably connected in the U-shaped slot S1. The bottom plate 101 is provided with a driving mechanism, and a turntable is rotatably connected to the bottom plate 101. An extension mechanism is installed on the turntable, and the end of the extension mechanism is in sliding cooperation with the flexible troweling plate 200. The driving mechanism can drive the turntable to rotate.

[0020] For ease of understanding, some key terms in the present embodiment are explained as follows: The main frame refers to the external support structure that carries the concrete finishing construction component. The main frame can be an existing concrete finishing construction device, such as a large troweling machine, or a walking trolley with a traveling mechanism, which can move the entire construction component within the construction area.

[0021] The mounting rack 100 refers to the basic support structure of the concrete finishing construction component. The mounting rack 100 is used to fix and support various components within the component, ensuring its stability and accuracy during operation.

[0022] The bottom plate 101 refers to the bottom platform of the mounting rack 100. The bottom plate 101 provides a stable mounting surface for the component, on which components such as driving mechanisms and turntables can be installed.

[0023] The side plate 102 refers to the vertical plate on both sides of the bottom plate 101 of the mounting rack 100. The side plate 102 cooperates with the bottom plate 101 to form a structured support space and defines the lateral boundary of the U-shaped slot S1.

[0024] The U-shaped slot S1 refers to the U-shaped open space formed by the overhanging ends of the base plate 101 and the two side plates 102. The U-shaped slot S1 is designed to accommodate the flexible plastering panel 200 and allow it to rotate within it.

[0025] Flexible plastering panel 200 refers to a plate-like structure with a certain degree of flexibility, used for direct contact with concrete surfaces for smoothing operations. The flexibility of the flexible plastering panel 200 allows it to adapt to the edges of obstacles of different shapes, achieving precise plastering.

[0026] A drive mechanism is a device that provides power to a component to achieve a specific movement. In this embodiment, the drive mechanism is configured to drive the turntable to rotate, thereby changing the orientation of the telescopic mechanism.

[0027] A turntable is a rotatable circular or disc-shaped component. The turntable is mounted on a base plate 101 and is driven to rotate by a drive mechanism. A telescopic mechanism is installed on the turntable, and its working direction can be changed by rotating it.

[0028] A telescopic mechanism is a mechanical device capable of extending or retracting in length. One end of the telescopic mechanism is mounted on a turntable, and the other end slides in engagement with the flexible trowel panel 200. Its telescopic movement can change the curvature of the flexible trowel panel 200.

[0029] This embodiment provides a concrete plastering construction component designed to be installed on a main frame. The main frame can be an existing concrete plastering construction device, such as a large plastering machine, or a traveling trolley with a travel mechanism. The component can be connected to the main frame using various methods such as bolt fixing, welding, or quick-connect fitting to ensure the stability and reliability of the component during construction. The type of main frame is selected based on specific construction requirements and compatibility with existing equipment.

[0030] The construction component includes a mounting frame 100. The mounting frame 100, serving as the skeleton of the entire component, can be constructed from metal profiles or plates through welding, riveting, or bolting to provide sufficient structural strength and rigidity. For example, the mounting frame 100 can be made of steel or aluminum alloy to balance strength and lightweight.

[0031] Mounting bracket 100 includes a base plate 101. The base plate 101 is typically a flat, plate-like structure, and its material can be high-strength steel plate or composite material. The base plate 101 is configured to support other components in the structure, such as drive mechanisms, turntables, etc., and to provide them with a stable mounting surface.

[0032] Each side of the base plate 101 is provided with a side plate 102. The side plate 102 can be connected to the base plate 101 perpendicularly or at a certain angle, and the connection method can be welding, bolting, or integral molding. The function of the side plate 102 is to provide lateral support and guidance for the flexible plastering panel 200 and to define the structure of the U-shaped groove S1.

[0033] Two side panels 102 extend to one side of the base plate 101 to form overhanging ends. The extended portions of the side panels 102 can extend beyond the edge of the base plate 101, forming an open working area. This overhanging design allows the flexible plastering panel 200 to rotate and bend freely within this area to adapt to different construction environments.

[0034] The overhanging ends of the two side plates 102 together with the base plate 101 form a U-shaped groove S1. The shape and size of the U-shaped groove S1 can be designed according to the size of the flexible plastering panel 200 and the required rotation range. For example, the U-shaped groove S1 can be a rectangular or arc-shaped opening, and its inner surface can be smoothed to reduce friction when the flexible plastering panel 200 rotates.

[0035] A flexible plastering panel 200 is rotatably connected within the U-shaped groove S1. The flexible plastering panel 200 can be made of rubber, polyurethane, or other materials with suitable flexibility and abrasion resistance. The rotatable connection of the flexible plastering panel 200 is achieved by providing shaft holes in the side plate 102 of the U-shaped groove S1 and connecting the flexible plastering panel 200 to it via pins or hinges. This rotatable connection allows the flexible plastering panel 200 to swing around an axis, thereby adjusting its contact angle with the concrete surface.

[0036] A drive mechanism is provided at the bottom of the base plate 101. This drive mechanism can be a hydraulic motor, a pneumatic motor, or a stepper motor, etc. This drive mechanism is configured to provide rotational power and is connected to the turntable through a transmission device such as gears, chains, or belts, thereby driving the turntable to rotate.

[0037] A turntable is rotatably connected to the base plate 101. The turntable can be a circular or polygonal platform, which is connected to the base plate 101 via bearings or a rotating joint to ensure smooth rotation. The center of rotation of the turntable can be located at the geometric center of the base plate 101 or at an off-center position to meet different motion requirements.

[0038] A telescopic mechanism is installed on the turntable. This mechanism can be a pneumatic cylinder, electric cylinder, or hydraulic cylinder, fixed to the turntable and rotating with it. The installation position and direction of the telescopic mechanism can be adjusted according to the bending requirements of the flexible plastering panel 200.

[0039] The end of the telescopic mechanism slides into the flexible trowel panel 200. The telescopic rod end of the telescopic mechanism can directly contact the back of the flexible trowel panel 200, achieving sliding through a low-friction material or coating. Alternatively, the end of the telescopic mechanism can be connected to a simple slider that slides on a pre-set guide rail on the back or inside of the flexible trowel panel 200, thereby achieving a pushing and pulling action of the telescopic mechanism on the flexible trowel panel 200.

[0040] The concrete plastering construction component of this embodiment achieves flexible adjustment of the angle and curvature of the plastering panel 200 through the rotational connection of the flexible plastering panel 200 and the sliding cooperation between the telescopic mechanism and the flexible plastering panel 200. Therefore, this component can effectively adapt to the edge shapes of vertical obstacles such as wall corners and supporting columns, and precisely handle boundary areas that are difficult to reach with traditional devices, thereby eliminating "dead zones" in construction. The integrated design of this component significantly improves the automation level and overall efficiency of concrete plastering construction, reducing reliance on secondary manual operations.

[0041] In some of the embodiments described above in this application, a drive mechanism is proposed to drive the turntable to rotate. However, in its implementation, the use of non-motor drive methods may be inefficient or unreliable, affecting the overall automation and stability of the construction.

[0042] In this regard, this application further proposes that the driving mechanism is an electric motor. An electric motor is a device that converts electrical energy into mechanical energy, generating torque through the principle of electromagnetic induction, thereby driving mechanical components to rotate. In concrete plastering construction components, the motor, as the driving mechanism, can provide stable and controllable power to the turntable. Specifically, the motor can be an AC motor, such as an asynchronous motor or a synchronous motor, characterized by its robust structure and reliable operation, suitable for applications requiring long-term continuous operation, and achieving precise speed and torque regulation through control units such as frequency converters. Alternatively, the motor can be a DC motor, such as a brushed DC motor or a brushless DC motor, characterized by good speed regulation performance and fast response speed, especially suitable for scenarios requiring frequent starts and stops or precise position control. Furthermore, to achieve high-precision positioning and motion control, stepper motors or servo motors can also be used, which can provide precise angular displacement control, ensuring the rotational accuracy of the turntable.

[0043] In some of the embodiments described above in this application, a rotating connection of a flexible plastering panel is proposed to enable plastering operations that adapt to obstacles. However, in the process of implementation, the connection method may not be stable or precise enough, resulting in the instability of the position of the flexible plastering panel when vibrating or bending, which affects the treatment quality of the concrete surface.

[0044] In this regard, this application further proposes that the suspended end of the side plate 102 is provided with a rotating shaft 103, the rotating shaft 103 passes through the side plate 102 and is connected to an end plate 104, and a flexible troweling panel 200 is fixed between the two end plates 104.

[0045] Specifically, the pivot 103 is a key component for supporting and allowing the flexible trowel panel 200 to rotate. It provides a stable center of rotation, ensuring that the flexible trowel panel 200 can rotate precisely and controllably around a fixed axis, thus adapting to different troweling angles and obstacle shapes. The pivot 103 can be a solid or hollow cylindrical rod, with both ends fixed to the suspended ends of the side plate 102 by bearing seats or bushings to reduce friction and ensure smooth rotation. Alternatively, the pivot 103 can also be securely connected to the side plate 102 by bolts, welding, or other means, with its outer surface precision-machined to provide a smooth rotation interface.

[0046] End plate 104, as a structural component connecting shaft 103 and flexible troweling panel 200, is typically plate-shaped and provides a robust connection interface. As a transition and connection between shaft 103 and flexible troweling panel 200, it precisely transmits the rotation of shaft 103 to flexible troweling panel 200 and ensures the integrity of flexible troweling panel 200 during rotation. End plate 104 can be securely fixed to the end of shaft 103 via key connection, pin connection, bolt connection, or welding, ensuring no relative rotation between the two. Alternatively, end plate 104 can be designed with a central hole, connecting to shaft 103 via interference fit or set screws to achieve reliable torque transmission.

[0047] "Fixed connection" refers to a firm, non-movable connection between the flexible plastering panel 200 and the two end plates 104. This connection method ensures that the flexible plastering panel 200 can work as a whole with the end plates 104 and the rotating shaft 103 when rotating, bending, or vibrating, avoiding loosening or displacement, thereby ensuring the accuracy and stability of the plastering operation. The flexible plastering panel 200 can be directly fixed between the two end plates 104 by means of bolts, rivets, adhesives, or welding. For example, mounting holes can be pre-drilled at both ends of the flexible plastering panel 200, which can be aligned with the corresponding holes on the end plates 104 and then tightened with bolts. Alternatively, the flexible plastering panel 200 can also be designed to fit with a specific structure (such as a groove or flange) of the end plates 104, and then fixed by means of pressing, snapping, or injection to form an integrated connection.

[0048] Through the above technical solution, the flexible plastering panel 200 forms a structurally stable and precisely rotating connection via the rotating shaft 103, end plate 104, and fixed connection method. This connection method significantly enhances the positional stability of the flexible plastering panel 200 during operation, especially when it bends and deforms to conform to the corner angle or the curved edge of the support column, and when the vibrator 201 vibrates, effectively preventing unnecessary shaking or displacement of the flexible plastering panel 200. This allows the flexible plastering panel 200 to more accurately adapt to various complex obstacle surfaces and ensure the quality and uniformity of concrete plastering operations, thus effectively solving the problem of unstable position of the flexible plastering panel during vibration or bending, which affects the quality of concrete surface treatment.

[0049] In some of the solutions described above in this application, a pivot is proposed for connecting a flexible plastering panel. However, in this process, the pivot may not be able to be fixed in position, causing the flexible plastering panel to be unstable during operation and unable to accurately conform to the edge of vertical obstacles such as walls or columns, thereby affecting the construction quality and efficiency.

[0050] In response, this application proposes an improvement: a shaft locking mechanism that cooperates with the rotating shaft 103 is installed on the side plate 102. This shaft locking mechanism is a mechanical device used to fix or restrict the rotation of the rotating shaft 103. Its core function is to reliably lock the rotating shaft 103 in its preset position under specific working conditions, thereby ensuring the stability of the posture of the flexible trowel panel 200 connected to the rotating shaft 103.

[0051] Specifically, the shaft locking mechanism can be implemented in various ways. For example, a friction locking mechanism can be used, which includes one or more brake blocks or clamps that act on the outer surface of the rotating shaft 103 through hydraulic, pneumatic, or mechanical force to generate sufficient friction to prevent the rotation of the rotating shaft 103. When locking is required, the brake blocks or clamps tighten; when releasing is required, the brake blocks or clamps loosen. Another implementation is to use a positive locking mechanism, such as a pin-type locking mechanism or a toothed locking mechanism. A pin-type locking mechanism can have preset holes or grooves on the rotating shaft 103, and the locking mechanism achieves mechanical locking of the rotating shaft 103 by extending a pin and inserting it into these holes or grooves. A toothed locking mechanism can have a toothed structure on the rotating shaft 103, and the locking mechanism achieves locking through the meshing toothed components. In addition, an electromagnetic locking mechanism can be used, which uses electromagnetic force to engage or disengage the brake disc, thereby achieving locking or releasing of the rotating shaft 103.

[0052] By installing a shaft-locking mechanism on the side plate 102 that cooperates with the rotating shaft 103, this application effectively solves the problem of unstable position of the flexible plastering panel 200 in a specific working mode. When the shaft-locking mechanism locks the rotating shaft 103, it can fix the flexible plastering panel 200 in a vertical position, making it stable when the drive mechanism is stationary. This stability allows the telescopic mechanism to precisely adjust the curvature of the flexible plastering panel 200, so that it can closely fit the corner angle or the arc edge of the support column, greatly improving the smoothing accuracy and quality of the edge area. At the same time, when large-area smoothing work is required, the shaft-locking mechanism can release the lock on the rotating shaft 103, allowing the flexible plastering panel 200 to rotate freely around the rotating shaft 103. With the extension and retraction of the electric cylinder, the left side of the flexible plastering panel 200 can contact the concrete for large-area smoothing. This design ensures that the concrete plastering construction components can flexibly adapt to the needs of different construction scenarios, significantly improving the degree of automation in construction and the ability to handle the edges of complex obstacles, avoiding the need for manual secondary smoothing, thereby improving overall construction efficiency and reducing labor costs.

[0053] In some of the embodiments described above in this application, concrete plastering construction components are proposed for plastering construction. However, during the implementation process, phenomena such as honeycomb pitting may occur on the concrete surface, resulting in insufficient density and affecting strength.

[0054] In this regard, this application further proposes that the flexible plastering panel 200 has a plurality of vertical insertion holes, and a vibrator 201 is installed in the vertical insertion holes. The vibrator is used to make the concrete compact and eliminate phenomena such as honeycomb and pitting in the concrete, thereby improving its strength.

[0055] Specifically, the flexible plastering panel 200 has several vertical insertion holes formed within it. These vertical insertion holes provide installation and fixing positions for the vibrator 201. In practical applications, these vertical insertion holes can be implemented in various ways. For example, during the manufacturing process of the flexible plastering panel 200, regularly arranged vertical channels can be directly formed inside the panel through mold forming or subsequent drilling to allow the vibrator 201 to be inserted. Alternatively, a sleeve made of metal or polymer material can be pre-embedded inside the flexible plastering panel 200 as an insertion guide and support structure for the vibrator 201. The design of these vertical insertion holes aims to ensure that the vibrator 201 can be stably installed inside the flexible plastering panel 200 and its vibration energy can be effectively transferred to the concrete, while preventing the vibrator 201 from shifting or falling off during operation.

[0056] A vibratory rod 201 is installed inside the vertical insertion hole. The vibratory rod 201 is a device capable of generating high-frequency vibration, typically driven by an eccentric block by a motor or electromagnetically, used for internal compaction of concrete. The vibratory rod 201 can be implemented as a mechanical vibratory rod, which generates vibration by rotating an internal eccentric block driven by a small motor, with its outer sleeve tightly fitted into the vertical insertion hole. Another implementation is a high-frequency electric vibratory rod, which uses a high-frequency motor to directly drive the vibrating head, powered by a cable. The vibratory rod 201 can be inserted into the vertical insertion hole and secured by snaps, threads, or friction fit. The vibratory rod 201 is designed to apply vibrational energy directly to the interior of the concrete, causing air bubbles to escape and aggregates to rearrange, thereby increasing the density of the concrete.

[0057] Vibratory rods are used to compact concrete, eliminate honeycomb and pitting defects, and improve strength. This is the core function and technical effect of vibratory rod 201. The high-frequency vibration generated by vibratory rod 201 reduces the friction between concrete particles, causing them to rearrange under gravity, expelling excess air and moisture, and filling voids, thus achieving compaction. The compacted concrete surface is less prone to defects such as honeycomb and pitting, and its overall strength is significantly improved.

[0058] Through the above technical solution, during the finishing process of the concrete finishing construction component, the internal vibrator 201 can work synchronously to generate high-frequency vibration. These vibrations are transmitted to the interior of the concrete through the flexible finishing panel 200, causing air bubbles in the concrete to rise and be expelled. Aggregate particles rearrange under the vibration, filling the gaps, thereby achieving concrete compaction. Given that the flexible finishing panel 200 itself has bendable characteristics and can adapt to complex areas such as corner angles or curved edges of supporting columns, the integrated vibrator 201 can also perform synchronous vibration in these irregular areas, ensuring that even in areas difficult to handle with traditional finishing devices, the concrete achieves uniform compaction. This not only effectively solves problems such as honeycomb surface defects and insufficient compaction that may occur during concrete finishing, significantly improving the overall strength and surface quality of the concrete, but also avoids the cumbersome additional vibration process required in traditional construction, improving construction efficiency and automation. Especially when dealing with the edges of complex structures, it ensures uniform compaction of the concrete, thereby improving the overall quality and efficiency of the concrete finishing construction.

[0059] In some of the embodiments described above in this application, the end of the telescopic mechanism is proposed to slide with the flexible plastering panel to adjust the position and angle of the flexible plastering panel. However, in its implementation, direct sliding may not be able to effectively distinguish between moving and bending actions, resulting in insufficient flexibility when fitting the corner of the wall or supporting column, and dead zones cannot be avoided, affecting construction accuracy and efficiency.

[0060] In this regard, this application further proposes that the back of the flexible trowel panel is provided with a groove 41, the groove being flexible, a slider 42 being slidably fitted inside the groove, a connecting plate 43 being provided on the slider, and the connecting plate being rotatably connected to the end of the telescopic mechanism.

[0061] Specifically, the groove 41 on the back of the flexible plastering panel 200 serves to provide a preset sliding path for the slider 42, guiding the slider 42 to make precise position adjustments on the back of the flexible plastering panel 200. This groove 41 can be flexible, meaning it can deform itself as the flexible plastering panel 200 bends, thus ensuring that the groove 41 does not obstruct the bending action when the flexible plastering panel 200 needs to bend to conform to non-planar obstacles. For example, the groove 41 can be integrally formed on the back of the flexible plastering panel 200, made of the same flexible material as the flexible plastering panel 200; or, the groove 41 can be a separately manufactured flexible guide rail, fixed to the back of the flexible plastering panel 200 by bonding, riveting, or other methods.

[0062] The slider 42 is disposed within the slide groove 41 and slides in cooperation with it. The main function of the slider 42 is to move along the path of the slide groove 41 under the push of a telescopic mechanism (e.g., an electric cylinder 32), thereby achieving overall or partial position adjustment of the flexible trowel panel 200. The design of the slider 42 should ensure smooth sliding within the slide groove 41 while possessing sufficient stability. For example, the slider 42 can adopt a T-shaped, dovetail-shaped, or cylindrical structure, and its material can be selected from engineering plastics with a low coefficient of friction (such as polytetrafluoroethylene, polyoxymethylene) or metal materials with a low-friction surface treatment.

[0063] The connecting plate 43 is fixed to the slider 42, serving as a connecting bridge between the slider 42 and the end of the telescopic mechanism. Its function is to transmit the thrust or pull force of the telescopic mechanism to the slider 42, thereby affecting the movement or deformation of the flexible trowel panel 200. The connecting plate 43 is typically a rigid structure to ensure effective force transmission. For example, the connecting plate 43 can be a flat metal plate or a high-strength plastic plate, or it can be an L-shaped or Z-shaped bracket to adapt to different spatial layouts and connection requirements.

[0064] The connecting plate 43 is rotatably connected to the end of the telescopic mechanism. This connection allows the connecting plate 43 to rotate at a certain angle relative to the end of the telescopic mechanism, thus accommodating possible bending or angular changes in the flexible trowel panel 200 when the telescopic mechanism pushes the slider 42, avoiding stress concentration or motion interference caused by rigid connections. The rotatable connection can be achieved through pin connections, ball joints, or universal joints, ensuring that the thrust of the telescopic mechanism can act smoothly and flexibly on the flexible trowel panel 200 under different working conditions.

[0065] Through the above technical solution, the groove 41 on the back of the flexible plastering panel 200, the slider 42 slidingly engaged within the groove 41, and the connecting plate 43 on the slider 42 connected to the end of the telescopic mechanism via a rotatable connection, together constitute a sophisticated linkage mechanism. When the shaft locking mechanism locks the rotating shaft 103 and the drive mechanism remains stationary, the telescopic rod of the telescopic mechanism (electric cylinder 32) extends or retracts, precisely driving the flexible plastering panel 200 to bend via the connecting plate 43 and the slider 42. At this time, the flexible groove 41 can adapt to the bending deformation of the flexible plastering panel 200, while the rotatable connection between the connecting plate 43 and the end of the telescopic mechanism can compensate for the angle change caused by bending, ensuring that the thrust of the telescopic mechanism is effectively converted into bending torque, thereby allowing the flexible plastering panel 200 to flexibly conform to the corner angle of the wall or the arc edge of the support column, effectively eliminating construction dead zones.

[0066] On the other hand, when the drive mechanism is activated, the telescopic rod of the telescopic mechanism (electric cylinder 32) extends or retracts. Through the connecting plate 43 and the slider 42, the slider 42 can move along the slide groove 41 without causing bending deformation of the flexible trowel panel 200. In this mode, the rotary connection allows the telescopic mechanism to adapt its posture to the slight swaying or adjustment of the flexible trowel panel 200 when pushing the slider 42 to translate, while the sliding of the slider 42 in the slide groove 41 ensures that the flexible trowel panel 200 can be adjusted in its overall or partial position without being forcibly bent. This design allows the flexible trowel panel 200 to maintain its straight state when large-area troweling work is required, achieving efficient translational troweling.

[0067] In summary, this technical solution, by introducing the groove 41, the slider 42, and the rotating connecting plate 43, effectively decouples and precisely controls the movement and bending motions of the flexible plastering panel 200. This not only overcomes the limitations of traditional sliding fits in distinguishing between movement and bending motions, significantly improving the flexibility and adaptability of the flexible plastering panel 200 when conforming to complex obstacles, but also ensures construction accuracy and efficiency in different working modes, thereby effectively avoiding dead zones, reducing the need for manual secondary processing, and improving the automation level of concrete plastering construction.

[0068] In some of the embodiments described above in this application, a telescopic mechanism is proposed to control the bending and rotation of the flexible plastering panel to adapt to different construction environments. However, in its implementation, the type of telescopic mechanism may lack sufficient control precision and response speed, resulting in reduced construction efficiency and unsatisfactory plastering effect.

[0069] In this regard, this application further proposes that the telescopic mechanism is an electric cylinder 32.

[0070] The electric cylinder 32, as a device that converts the rotary motion of an electric motor into linear reciprocating motion, achieves precise linear displacement through a transmission mechanism such as a lead screw or synchronous belt driven by a motor. The electric cylinder 32 boasts advantages such as compact structure, high control precision, fast response speed, ease of programming and control, and convenient maintenance. In terms of specific implementation, the electric cylinder 32 can employ a combination of a ball screw and a servo motor, achieving micron-level displacement accuracy and rapid response through precise position control of the servo motor; alternatively, it can use a trapezoidal lead screw and a stepper motor, providing a more economical solution while ensuring a certain level of accuracy. Furthermore, the electric cylinder 32 can integrate position sensors and force sensors to achieve closed-loop control, further enhancing its adaptability and reliability under complex working conditions.

[0071] By specifically defining the telescopic mechanism as an electric cylinder 32, this application effectively solves the shortcomings of the telescopic mechanism in the above-mentioned solutions in terms of control precision and response speed. As a high-precision linear drive device, the electric cylinder 32 can achieve precise control over the telescopic movement of the flexible plastering panel 200. When it is necessary to adjust the curvature of the flexible plastering panel 200 to fit the corner angle of a wall or the arc-shaped edge of a supporting column, the electric cylinder 32 can telescopically extend and retract with extremely high precision and stability, ensuring that the flexible plastering panel 200 can accurately and quickly reach the preset bending state, thereby achieving close contact with the edges of various complex obstacles. Simultaneously, the rapid response characteristics of the electric cylinder 32 allow for quick adjustment of the posture of the flexible plastering panel 200 according to actual needs during construction, improving the flexibility and efficiency of construction. This precise and rapid control capability significantly reduces the need for manual secondary smoothing, improves the automation level and overall quality of concrete plastering construction, and avoids the problem of unsatisfactory smoothing results caused by inaccurate control.

[0072] In some of the embodiments described above in this application, a flexible trowel is proposed for smoothing concrete. However, during its implementation, concrete slurry is prone to splashing onto the top area, causing environmental pollution or affecting equipment operation.

[0073] In this regard, this application further proposes that a mudguard 5 be provided on the top of the flexible plastering panel 200. The mudguard 5 is designed as a physical barrier to effectively intercept mud splashes that may occur during concrete plastering operations. The mudguard 5 can be implemented using various materials and structural forms. For example, it can be made of corrosion-resistant metal sheets (such as stainless steel or aluminum alloy) and fixed to the top edge of the flexible plastering panel 200 by welding, bolting, or riveting. Alternatively, the mudguard 5 can be integrally molded from high-strength plastics (such as PVC or ABS) or composite materials to reduce weight and simplify the manufacturing process. The shape and size of the mudguard 5 can be designed according to actual needs; for example, it can be designed as a rectangular plate with a certain height and width, or as an arc shape according to the curvature of the flexible plastering panel 200 to maximize its blocking effect.

[0074] Through the above technical solution, when the flexible troweling panel 200 performs concrete troweling operations, especially when it is rotated to a horizontal position for large-area troweling, the mudguard 5 can effectively extend vertically upwards, forming a barrier. This barrier can prevent concrete slurry from splashing upwards during vibration or troweling, thus preventing slurry from splashing onto the base plate 101 of the mounting frame 100, the telescopic mechanism (e.g., the electric cylinder 32), and other driving components. This not only helps maintain a clean construction environment and reduces subsequent cleaning work, but more importantly, it effectively protects the precision components inside the equipment from slurry erosion and contamination, thereby extending the service life of the equipment and improving its operational reliability and stability. At the same time, reducing slurry splashing also reduces the potential impact on operators and improves the overall safety of construction.

[0075] In some of the embodiments described above in this application, a drive mechanism is used to rotate the turntable, and then the position and angle of the flexible plastering panel are adjusted by means of a telescopic mechanism to adapt to different construction scenarios. However, in actual operation, the weight of the telescopic mechanism may put pressure on the flexible plastering panel and cause elastic deformation.

[0076] In this regard, this application further proposes that an arc-shaped slide rail 331 is provided on the base plate, an arc-shaped slider 332 is slidably fitted on the arc-shaped slide rail, a vertical electric cylinder 333 is rotatably connected to the arc-shaped slider, and the end of the telescopic rod of the vertical electric cylinder is rotatably connected to the bottom of the telescopic mechanism.

[0077] Specifically, the arc-shaped slide rail 331 on the base plate serves to provide a preset arc-shaped sliding path for the arc-shaped slider 332, guiding the slider 332 to make precise position adjustments on the base plate according to a specific arc trajectory. The design of the arc-shaped slide rail 331 fully considers the complex spatial requirements that may be encountered in construction scenarios. Its curvature can be customized according to the actual construction situation to ensure that it can meet the finishing requirements of the edges of obstacles of different shapes. For example, the arc-shaped slide rail 331 can be precisely machined into an arc groove on the base plate through processes such as milling and grinding; or it can be directly integrally formed with the base plate using mold casting, improving the overall integrity and stability of the structure.

[0078] An arc-shaped slider 332 is disposed within an arc-shaped slide rail 331 and slides in conjunction with the slide rail 331. The design of the arc-shaped slider 332 should ensure smooth sliding within the arc-shaped slide rail 331, while possessing sufficient strength and stability to withstand various loads during construction. For example, the arc-shaped slider 332 can be made of high-strength alloy material, with its surface precision machined and heat-treated to improve wear resistance and fatigue resistance; its shape can be designed as an arc-shaped block structure that matches the arc-shaped slide rail 331, increasing the contact area and improving sliding stability.

[0079] The vertical electric cylinder 333 is rotatably connected to the arc-shaped slider 332. As a crucial power output component of the entire adjustment mechanism, its function is to convert electrical energy into linear reciprocating motion. Through the extension and retraction of the telescopic rod, the vertical position of the telescopic mechanism is adjusted. The vertical electric cylinder 333 typically possesses high control precision and response speed, enabling precise control of the telescopic rod's stroke and speed according to construction requirements.

[0080] The telescopic rod end of the vertical electric cylinder is rotatably connected to the bottom of the telescopic mechanism. As a key component that directly adjusts the position and angle of the flexible plastering panel, the telescopic mechanism's movement needs to be coordinated with the movements of the vertical electric cylinder 333 and the arc-shaped slider 332. For example, when facing a corner of a wall or the edge of a support column with complex curvature, the arc-shaped slider 332 moves along the arc-shaped slide rail 331, while the telescopic rod of the vertical electric cylinder 333 extends and retracts as needed. The two work together to enable the telescopic mechanism to drive the flexible plastering panel to precisely conform to the edge of the obstacle, achieving high-quality plastering operations.

[0081] Through the above technical solution, the arc-shaped slide rail 331, the arc-shaped slider 332, the vertically connected electric cylinder 333, and the telescopic mechanism rotatably connected to the end of the telescopic rod of the vertically connected electric cylinder on the base plate together constitute a highly flexible and precise linkage adjustment system. During construction, when complex adjustments to the position and angle of the flexible plastering panel are required, the arc-shaped slider 332 slides on the arc-shaped slide rail 331, driving the vertically connected electric cylinder 333 to change its position in the arc direction; at the same time, the telescopic rod of the vertically connected electric cylinder 333 extends and retracts according to actual needs, adjusting the position of the telescopic mechanism in the vertical direction; the telescopic mechanism further transmits the motion to the flexible plastering panel, enabling it to accurately conform to the edges of obstacles with various complex shapes. This design allows the flexible plastering panel to achieve a high degree of conformity when facing obstacles with special curvatures or irregular shapes, effectively eliminating construction dead zones that are difficult to handle with traditional adjustment methods, and significantly improving the plastering effect and construction quality.

[0082] On the other hand, this linkage adjustment system also plays a crucial role when large-area smoothing work is required. By rationally controlling the movement of the arc-shaped slider 332, the extension and retraction of the vertical electric cylinder 333, and the action of the telescopic mechanism, the flexible smoothing panel can be kept flat and large-area smoothing operations can be performed according to a predetermined trajectory, achieving efficient construction operations. This design not only improves the flexibility of construction and adapts to the needs of different construction scenarios, but also ensures the accuracy and efficiency of construction, greatly reduces the need for secondary manual processing, and further enhances the automation level of concrete smoothing construction.

[0083] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any 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.
