Description

Technical Field

[0001] This invention belongs to the field of floor tile laying technology, specifically a floor tile laying auxiliary device. Background Technology

[0002] In the process of laying floor tiles, leveling the tiles is a crucial step to ensure full adhesion between the tiles and the base mortar and to eliminate hollow areas. Currently, tile leveling is mainly achieved through two methods: manual operation or mechanical assistance. One method involves workers using rubber mallets or wooden mallets to tap the tile surface, causing slight displacement and adjusting its flatness to compact the mortar layer. Workers rely on their experience and feel to judge the tapping force, repeatedly tapping to find uneven areas until visually level. The second method uses mechanical assistance, including: using a motor to drive an eccentric block to generate high-frequency vibration, placing a tool on the tile surface to cause synchronous vibration and compaction; using a cam mechanism, spring assembly, or cylinder to drive a single tapping rod or block to reciprocate tapping the tile surface at a single point; some devices allow for multi-point tapping by manually moving the tapping head to different positions; and using a multi-degree-of-freedom robotic arm with a specialized end-effector integrated into the end effector of a tile-laying robot to perform the tapping action.

[0003] However, manual tapping relies heavily on the operator's personal experience and tactile judgment. Differences in worker skill levels lead to uneven tapping force, making it difficult to guarantee consistent construction quality. Furthermore, manual point-by-point tapping is inefficient, and prolonged work can cause fatigue, further affecting tapping accuracy and consistency. Mechanical tapping devices are mostly single-point tapping mechanisms or full-surface vibrating tools. Single-point tapping devices require manual movement of the tapping head to different positions, which is not only cumbersome but also makes it difficult to guarantee the accuracy and consistency of tapping points. While full-surface vibrating tools can cover the entire tile at once, the vibration energy is evenly distributed across the entire tile surface, making it impossible to apply differentiated tapping force to different areas. In conclusion, how to achieve precise tapping at the four corners of tiles, specifically addressing the problem of hollow corners, while reducing reliance on manual experience, is a pressing technical problem to be solved in the field of tile tapping and leveling. Summary of the Invention

[0004] To address the problem mentioned in the background section that it is difficult to accurately tap the four corners of a tile in the prior art, the present invention provides a tile laying auxiliary device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tile laying auxiliary device, comprising a mobile platform, and further comprising: A lifting mechanism is mounted on the mobile platform; A fixing plate is disposed at the output end of the lifting mechanism; A steering mechanism is connected to the bottom of the fixed plate via a hydraulic cylinder, wherein the fixed end and the movable end of the hydraulic cylinder are respectively connected to the fixed plate and the ball shaft of the steering mechanism; A drive mechanism, which is disposed on the steering mechanism; A driven mechanism is disposed on the steering mechanism and is connected to the drive mechanism in a transmission manner; A striking mechanism is provided at the output end of the driven mechanism and connected to the bottom of the steering mechanism; The striking mechanism includes an elastic telescopic rod and a connecting rod, wherein the elastic telescopic rod is connected to the driven mechanism via the connecting rod.

[0006] Preferably, the steering mechanism includes a horizontal plate, a spherical shaft, a guide column, and a movable frame. The horizontal plate is disposed at the output end of the hydraulic cylinder, the spherical shaft is fixedly installed at the bottom of the horizontal plate, the guide column is annularly installed at the bottom of the spherical shaft, and the movable frame is rotatably sleeved on the spherical shaft.

[0007] Preferably, the driving mechanism includes a drive motor and a rotating shaft. The drive motor is mounted on the top of the horizontal plate, the rotating shaft is mounted on the output end of the drive motor, and a positioning block is mounted on the rotating shaft.

[0008] Preferably, the driven mechanism includes a movable column and a striking plate. The movable column slides axially on the surface of the guide column, the striking plate is installed on the outer side of the movable column, and the inner wall of the movable column is provided with a wave groove that cooperates with the positioning block.

[0009] Preferably, the striking mechanism further includes a striking block and an elastic guide. The elastic guide is installed in a ring at the bottom of the movable frame and sleeved on the outside of the elastic telescopic rod. The elastic guide causes the elastic telescopic rod to have an upward tendency through elastic force.

[0010] Preferably, the device further includes a positioning mechanism, which includes a limiting angle plate and a positioning square plate. The limiting angle plate is installed in a ring shape on the outside of the horizontal plate, and the positioning square plate is installed on the upper end of the movable frame. When the positioning square plate is parallel to the horizontal plate, the limiting angle plate and the positioning square plate are in contact.

[0011] Preferably, a level is also installed on the top of the leveling plate.

[0012] Preferably, the lifting mechanism is used to adjust the height of the fixed plate.

[0013] Preferably, the striking block is made of rubber or polyurethane elastomer.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a rotatable connection between a spherical shaft and a movable frame. After the striking block contacts the floor tile, the movable frame adaptively deflects according to the contact pressure. In the striking mechanism located at the four corners of the movable frame, the connecting rods have different heights in the vertical direction. The higher the corner of the floor tile is raised, the higher the corresponding connecting rod is, and the greater the stroke of the striking plate driving it to move, thus increasing the impact force. This allows for the application of differentiated striking forces to different areas, accurately solving the problem of hollow corners of floor tiles. It overcomes the shortcomings of existing technologies, such as the inability to differentiate force application through whole-surface vibration and the difficulty of covering the four corners with single-point striking.

[0015] In this invention, the striking block is made of rubber or polyurethane elastomer material, which produces elastic deformation when struck, so as to transmit effective leveling impact force and absorb impact energy. The elastic telescopic rod has the ability to stretch and deform when transmitting the striking force, further buffering the rigid impact. The dual buffering effect effectively avoids the chipping or breakage of the floor tiles. At the same time, the elastic material is wear-resistant and fatigue-resistant, ensuring a long service life.

[0016] This invention converts continuous rotary motion into reciprocating linear motion through a cam mechanism formed by a rotating shaft, a positioning block, and a wave groove. Combined with the automatic reset of the elastic guide and the elastic telescopic rod, it achieves high-frequency continuous gentle tapping, significantly reducing the reliance on human experience and tactile judgment.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention provides a tile laying auxiliary device, including a mobile platform 100, and further comprising: Lifting mechanism 200, which is mounted on the mobile platform 100; Fixed plate 300, fixed plate 300 is disposed at the output end of lifting mechanism 200; Steering mechanism 500 is connected to the bottom of fixed plate 300 via hydraulic cylinder 400. The fixed end and movable end of hydraulic cylinder 400 are respectively connected to fixed plate 300 and ball shaft of steering mechanism 500. Drive mechanism 700, which is mounted on steering mechanism 500; Driven mechanism 800 is mounted on steering mechanism 500 and is connected to drive mechanism 700 in a transmission manner; A striking mechanism 900 is located at the output end of the driven mechanism 800 and connected to the bottom of the steering mechanism 500; The striking mechanism 900 includes an elastic telescopic rod 910 and a connecting rod 930. The elastic telescopic rod 910 is connected to the driven mechanism 800 via the connecting rod 930.

[0021] The above scheme is adopted: the mobile platform 100 serves as the supporting base of the entire device, and its bottom is equipped with wheels to facilitate the movement of the device by construction personnel at the work site. Preferably, the wheels can be universal wheels with locking function so that the device can be stably fixed when precise positioning is required. The height of the fixed plate 300 is adjusted by the lifting mechanism 200 to accommodate different thicknesses of floor tiles and mortar layers; the hydraulic cylinder 400 is connected to the steering mechanism 500 via a ball joint, allowing the steering mechanism 500 to flexibly adjust its angle in three-dimensional space; the tapping mechanism 900 contacts the floor tile to achieve adaptive deflection, and the drive mechanism 700 drives the driven mechanism 800 to generate reciprocating motion. The impact force is transmitted to the tapping block 920 via the connecting rod 930 and the elastic telescopic rod 910, which performs high-frequency gentle tapping on the floor tile to eliminate hollow areas in the mortar layer and achieve flat floor tile laying; the entire system works in concert to complete multiple actions such as positioning, angle adjustment, drive transmission, and buffer tapping in sequence, realizing automated auxiliary operation of floor tile laying.

[0022] like Figure 2 As shown, the steering mechanism 500 includes a horizontal plate 510, a spherical shaft 520, a guide column 530, and a movable frame 540. The horizontal plate 510 is located at the output end of the hydraulic cylinder 400. The spherical shaft 520 is fixedly installed at the bottom of the horizontal plate 510. The guide column 530 is annularly installed at the bottom of the spherical shaft 520. The movable frame 540 is rotatably sleeved on the spherical shaft 520.

[0023] The above solution involves a rotatable connection between the spherical shaft 520 and the movable frame 540, allowing the movable frame 540 to be adjusted at multiple angles within space to accommodate the warping of floor tiles. A guide column 530 is annularly mounted on the bottom of the spherical shaft 520, providing circumferential positioning constraints for the driven mechanism 800. The vertical reciprocating motion of the driven mechanism 800 enables differentiated striking forces on the four striking mechanisms 900, precisely addressing the issue of hollow corners in floor tiles. The movable frame 540 is rotatably mounted on the spherical shaft 520, ensuring flexible rotation and reliable positioning, meeting the operational needs of dealing with inconsistent floor tile conditions.

[0024] like Figure 2 and Figure 4 As shown, the drive mechanism 700 includes a drive motor 710 and a rotating shaft 720. The drive motor 710 is mounted on the top of the horizontal plate 510, and the rotating shaft 720 is mounted on the output end of the drive motor 710. A positioning block 701 is mounted on the rotating shaft 720.

[0025] The above scheme is adopted: the drive motor 710 is used as the power source to provide stable and controllable drive power for the entire striking action; the rotating shaft 720 accurately transmits the rotational power of the drive motor 710 to the positioning block 701, realizing the effective transmission of power from the motor to the actuator; the positioning block 701 is installed on the rotating shaft 720, rotates synchronously with the rotating shaft 720 and cooperates with the wave groove 801 to drive the driven mechanism 800 to generate reciprocating motion in the vertical direction.

[0026] like Figure 3 and Figure 4As shown, the driven mechanism 800 includes a movable column 810 and a striking plate 820. The movable column 810 slides axially on the surface of the guide column 530, and the striking plate 820 is installed on the outer side of the movable column 810. The inner wall of the movable column 810 is provided with a wave groove 801 that cooperates with the positioning block 701.

[0027] The above scheme is adopted: through the cooperation of the wave groove 801 and the positioning block 701, the continuous rotational motion of the drive motor 710 is converted into the up-and-down reciprocating linear motion of the movable column 810, realizing the effective conversion of motion mode; the movable column 810 slides axially on the surface of the guide column 530, which provides precise sliding guidance and support to ensure the accuracy and stability of the motion trajectory of the movable column 810; the striking plate 820 is installed on the outside of the movable column 810, moves up and down with the movable column 810 and drives the connecting rod 930 to move, transmitting power to the elastic telescopic rod 910 to complete the striking action.

[0028] like Figure 5 and Figure 6 As shown, the striking mechanism 900 also includes a striking block 920 and an elastic guide 940. The elastic guide 940 is installed in a ring at the bottom of the movable frame 540 and sleeved on the outside of the elastic telescopic rod 910. The elastic guide 940 causes the elastic telescopic rod 910 to have an upward tendency through elastic force.

[0029] The above solution involves applying an upward elastic force to the elastic telescopic rod 910 via the elastic guide 940, enabling the elastic telescopic rod 910 to automatically reset and move upward after completing the striking action, thus achieving continuous reciprocating striking operations. The elastic telescopic rod 910, while transmitting striking force, also possesses the ability to extend and deform, buffering and absorbing the impact force and reducing the risk of damage to the tile surface from rigid impacts. The striking block 920, connected to the lower end of the elastic telescopic rod 910, applies the buffered impact force to the tile surface, completing the leveling striking operation.

[0030] like Figure 2 As shown, it also includes a positioning mechanism 600, which includes a limiting angle plate 610 and a positioning square plate 620. The limiting angle plate 610 is installed in a ring on the outside of the horizontal plate 510, and the positioning square plate 620 is installed on the upper end of the movable frame 540. When the positioning square plate 620 is parallel to the horizontal plate 510, the limiting angle plate 610 and the positioning square plate 620 are in contact.

[0031] The above solution is adopted: the horizontal rotation angle of the movable frame 540 is limited by the contact between the limiting angle plate 610 and the positioning square plate 620, so as to prevent the movable frame 540 from deflecting excessively in the horizontal direction and affecting the striking position and accuracy; the limiting angle plate 610 is installed in a ring on the outside of the horizontal plate 510, and the positioning square plate 620 is installed on the upper end of the movable frame 540. When the two are in contact, the movable frame 540 is limited to not rotate in the horizontal direction, so as to achieve reliable mechanical stop positioning.

[0032] like Figure 1 As shown, a level 501 is also installed on the top of the level plate 510.

[0033] The above solution involves using a level 501 to monitor the level of the level plate 510 in real time, providing the operator with an intuitive reference for levelness; ensuring that the device is level before operation, and guaranteeing the verticality of the striking direction and the consistency of the leveling effect.

[0034] like Figure 1 As shown, the lifting mechanism 200 is used to adjust the height position of the fixed plate 300.

[0035] The above solution is adopted: the height of the fixed plate 300 is adjusted by the lifting mechanism 200, thereby adjusting the vertical distance between the entire striking mechanism 900 and the surface of the floor tile, adapting to the construction needs of floor tiles and mortar layers of different thicknesses, and improving the versatility and adaptability of the device.

[0036] The striking block 920 is made of rubber or polyurethane elastomer.

[0037] The above solution involves using rubber or polyurethane elastomer as the material for the striking block 920. The elastic properties of the material generate buffer deformation during impact, effectively protecting the surface of the floor tile from hard damage. At the same time, this type of material has good wear resistance and fatigue resistance, ensuring the service life of the striking block 920 under frequent use conditions.

[0038] Working principle and usage process of this invention: First, the operator moves the entire device to the vicinity of the paving tile location using the mobile platform 100. The wheeled structure of the mobile platform 100 facilitates flexible transportation on the construction site. After the device is in place, the operator starts the lifting mechanism 200 to adjust the height of the fixed plate 300 and adjusts the striking mechanism 900 above the paving tile. The operator then uses the level 501 to observe whether the level plate 510 is level. If it is not level, the hydraulic cylinder 400 will correct it, laying the foundation for subsequent precise striking. After the horizontal alignment is completed, the operator aligns the striking block 920 with the four corners of the tile according to the position and angle requirements of the tile to be struck. The lifting mechanism 200 drives the steering mechanism 500 to move down, so that the striking block 920 contacts the tile. The contact pressure drives the movable frame 540 to rotate around the spherical shaft 520. The cooperation between the limiting angle plate 610 and the positioning square plate 620 prevents the movable frame 540 from rotating. After the angle adaptive adjustment is completed, the operator starts the drive motor 710. The drive motor 710 drives the positioning block 701 to rotate synchronously through the rotating shaft 720. As the core component of the cam mechanism, the positioning block 701 interacts with the wave groove 801 opened on the inner wall of the movable column 810 as it rotates with the rotating shaft 720. The movable column 810 slides axially up and down on the surface of the guide column 530. When the movable column 810 moves downward, the striking plate 820 descends accordingly and pushes the elastic telescopic rod 910 downward through the connecting rod 930. The elastic telescopic rod 910 compresses and transmits the impact force to the striking block 920, so that the striking block 920 acts on the surface of the floor tile with a certain impact force. Since the movable frame 540 rotates around the spherical shaft 520 through the contact pressure with the floor tile, the connecting rods 930 in the striking mechanism 900 located at the four corners of the movable frame 540 have different heights in the vertical direction. The greater the height of the corner of the floor tile, the higher the corresponding connecting rod 930 is. After the striking plate 820 contacts the connecting rod 930, the stroke of the connecting rod 930 is also greater, which in turn generates a greater impact force on the corner of the floor tile, thus applying differentiated striking force to different areas. The striking block 920 is made of rubber or polyurethane elastomer. When struck, it produces elastic deformation, which can transmit effective leveling impact force and absorb impact energy, thus buffering and protecting the surface of the floor tiles and preventing hard impacts from causing chipping or damage to the floor tiles. In addition, the elastic telescopic rod 910 can also extend and retract to buffer, further improving the protection of the floor tiles. After the tapping is completed, under the upward elastic force of the elastic guide 940 on the elastic telescopic rod 910 and the elastic force of the elastic telescopic rod 910 itself, the elastic telescopic rod 910 automatically extends and resets, preparing for the next tapping action. The movable column 810 continues to move up and down reciprocally under the continuous meshing action of the wave groove 801 and the positioning block 701, realizing high-frequency continuous tapping of the floor tile position. Through multiple gentle impacts, the mortar layer is made dense and the floor tiles are laid flat.
