Description

Technical Field

[0001] This invention relates to the field of compaction technology, and in particular to a device for compacting dry-hardened mortar on the ground. Background Technology

[0002] In building flooring construction, dry-hardened mortar (usually referring to a mortar mixture with a low water-cement ratio and loose granular form) is widely used as a dry-laying layer for floor tiles and stone, as well as a leveling layer for large-area concrete floors. The core aspect of its construction quality lies in compaction, that is, eliminating the voids between mortar particles through external force to achieve the required density, flatness, and load-bearing capacity, thereby effectively preventing surface hollowing, cracking, and uneven settlement.

[0003] Currently, the industry mainly relies on the following methods for compacting dry-hard mortar: Plate vibratory compaction: This is the most common mechanical compaction method. It uses high-frequency vibration generated by an electric motor to liquefy and rearrange mortar particles. However, this method has significant drawbacks: First, its vibration force is distributed in a "planar" manner, and the compaction effect on deep mortar decreases layer by layer, easily forming a "solid on top and loose at the bottom" structural layering; second, construction relies on the operator's "Z"-shaped movement path, and it is difficult to precisely control the movement speed and overlapping areas, which easily leads to areas of under-vibration or over-vibration, resulting in uneven density.

[0004] Vibrating beam / laser screed compaction: Suitable for large-area, high-precision flooring. While it can guarantee excellent overall flatness, the equipment is extremely expensive, has stringent requirements for the openness of the construction site and the pretreatment of the substrate, and is bulky, difficult to turn and finish, making it unsuitable for small to medium-sized projects or complex structural rooms.

[0005] Manual compaction: This method uses tools such as wooden rammers and iron rammers to compact the soil by hand. It is extremely labor-intensive, inefficient, and the compaction quality depends entirely on the worker's experience and physical strength. It also results in the worst uniformity of density and is a major cause of localized hollow areas and later deformation. Its use is now restricted in modern standard construction practices. Summary of the Invention

[0006] To overcome the problems existing in the prior art, the present invention provides a compaction device for dry hard mortar on the ground. This device is compact and highly flexible. It should be able to achieve uniform compaction of the full thickness of the dry hard mortar layer while ensuring high construction efficiency, reducing the dependence on the operator's personal skills, thereby fundamentally improving the construction quality and reliability of the floor base.

[0007] A ground dry hard mortar compaction device includes a lateral movement mechanism, a compaction mechanism, and a control system, wherein the lateral movement mechanism and the compaction mechanism are slidably connected vertically. The control system includes a controller, sensors, and a main power supply. The controller, sensors, and main power supply are electrically connected to each other. Two sensors are installed inside the compaction mechanism to detect the stroke position and contact pressure value, and convert the stroke position and contact pressure value into signals that are transmitted to the controller. The controller receives the signals transmitted by the sensors and controls the compaction mechanism to continuously press down and lift up according to the signals transmitted by the sensors through the main power supply. The lateral movement mechanism is powered by the main power supply to move laterally in the area covered by dry hard mortar, and drives the compaction mechanism to move laterally in the area covered by dry hard mortar. The compaction mechanism is controlled by the controller system to continuously press down and lift in the area covered by dry hard mortar, and is driven by the lateral movement mechanism to move laterally in the area covered by dry hard mortar.

[0008] Furthermore, the lateral movement mechanism includes a primary plate, a secondary plate, a tertiary plate, a primary drive assembly, and a secondary transmission assembly. The primary plate and the secondary plate are slidably connected, and the secondary plate and the tertiary plate are slidably connected. The primary drive assembly is disposed on the primary plate and drives the secondary plate to move laterally. The secondary transmission assembly is disposed on the secondary plate and the tertiary plate, and the secondary plate drives the tertiary plate to move laterally through the lateral movement of the secondary plate and the secondary transmission assembly.

[0009] Furthermore, two primary parallel track assemblies are provided on the other side of the primary plate. Each primary track assembly includes a primary track and a primary slider. The primary slider is slidably connected to the primary track. A rack is provided on one side of the secondary plate, and two secondary parallel track assemblies are provided on the other side of the secondary plate. Each secondary parallel track assembly includes a secondary track and a secondary slider. The secondary slider is slidably connected to the secondary track. The primary plate and the secondary plate are slidably connected by being fixedly connected by the secondary plate and the primary slider. The tertiary plate and the secondary plate are slidably connected by being fixedly connected by the tertiary plate and the secondary slider.

[0010] Furthermore, the primary drive assembly includes a transverse motor, a gear, and an L-shaped mounting base. The vertical side of the L-shaped mounting base is fixed to one side of the primary plate, and the horizontal plate of the L-shaped mounting base extends to the other side of the primary plate. The transverse motor is fixed to the vertical plate of the L-shaped mounting base, and the gear is connected to the drive shaft of the transverse power supply via a key connection. The gear meshes with a rack.

[0011] Furthermore, the secondary transmission assembly includes a transmission belt, rollers, fixed shafts, an upper clamping plate, and a lower pressure plate. The two fixed shafts are fixed to the upper ends of the secondary plate, and the two rollers are respectively inserted into the two fixed shafts. The transmission belt covers the rollers at both ends. The upper clamping plate is fixed to the top surface of the tertiary plate, and the upper layer of the transmission belt is clamped inside the upper clamping plate. The lower pressure plate is fixed to the horizontal plate of the L-shaped fixed seat, and the lower layer of the transmission belt is clamped between the lower pressure plate and the horizontal plate of the L-shaped fixed seat.

[0012] Furthermore, the compaction mechanism includes a protective cover, a lifting and pressing component, a flat pressing component, and an upper mounting base. The two ends of the lifting and pressing component are respectively hinged to the three-stage plate and the protective cover. The upper mounting base is fixed to the upper clamping plate. The lifting and pressing component is hinged to the three-stage plate through the upper mounting plate. The flat pressing component is disposed inside the protective cover. The protective cover is slidably connected to the three-stage plate.

[0013] Furthermore, guide grooves are provided on both sides of the protective cover, and guide rails are provided on both sides of the three-stage plate. The protective cover and the three-stage plate are slidably connected up and down in the guide grooves via the guide rails.

[0014] Furthermore, the lifting and pressing power component is an electric actuator, and the top panel of the protective cover is provided with a lower pin mounting hole. One end of the upper mounting base is fixed to the upper clamping plate, and the other end of the upper mounting base is an upper pin mounting hole. The upper end of the electric actuator is provided with a through upper pin hole, and the lower end of the electric actuator is provided with a through lower pin hole. The upper end of the electric actuator is hinged to the upper mounting base through a pin passing through the upper pin hole and the upper pin mounting hole, and the lower end of the electric actuator is hinged to the protective cover through a pin passing through the lower pin hole and the lower pin mounting hole.

[0015] Furthermore, the two sensors include a first sensor and a second sensor. The first sensor is disposed inside the electric actuator to detect the stroke position of the electric actuator and transmit the stroke position signal to the controller. The second sensor is disposed inside the middle support plate to detect the contact pressure value between the middle support plate and the ground and transmit the contact pressure value signal to the controller.

[0016] Furthermore, the controller is a single silicon chip, which contains multiple contact pressure values ​​B. The single silicon chip receives stroke position signals transmitted by the first sensor and controls the electric push rod to press down and lift up by controlling the main power supply according to the stroke position signals. The single silicon chip receives pressure value signals transmitted by the second sensor, converts the pressure value signals into corresponding pressure values ​​A, and compares pressure value A with contact pressure values ​​B until pressure value A and contact pressure values ​​B are equal. At the same time, according to the stroke position signals, the controller controls and locks the stroke position of the electric push rod to keep the middle support plate continuously pressed down.

[0017] The beneficial effects of this invention are as follows: (1) The present invention controls the compaction mechanism to maintain a constant and uniform pressure on the dry hard mortar through the control system. This avoids areas of "uneven hardness" caused by uneven pressure and greatly reduces the risk of hollowing. Under constant and uniform pressure, the entire mortar layer will sink and compress evenly, and the construction personnel can more accurately control the initial elevation of the paving. After compaction, the ideal flatness requirement can be easily achieved.

[0018] (2) The track in the compaction mechanism and the lateral movement mechanism of the secondary transmission in this invention realize the lateral movement coverage of twice the distance of the track polishing and grinding and the primary transmission distance. It is very stable in operation, and it is not easy to cause accidental jumping or deviation, which reduces the risk of rework, reduces labor costs, and ensures the service life and aesthetics of the subsequent flooring materials.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] A ground dry-hard mortar compaction device, such as Figures 1 to 3 As shown, it includes a lateral movement mechanism, a compaction mechanism, and a control system, wherein the lateral movement mechanism and the compaction mechanism are slidably connected vertically. The control system includes a controller, sensors, and a main power supply. The controller, sensors, and main power supply are electrically connected to each other. Two sensors are installed inside the compaction mechanism to detect the stroke position and contact pressure value, and convert the stroke position and contact pressure value into signals that are transmitted to the controller. The controller receives the signals transmitted by the sensors and controls the compaction mechanism to continuously press down and lift up according to the signals transmitted by the sensors through the main power supply. The lateral movement mechanism is powered by the main power supply to move laterally in the area covered by dry hard mortar, and drives the compaction mechanism to move laterally in the area covered by dry hard mortar. The compaction mechanism is controlled by the controller system to continuously press down and lift in the area covered by dry hard mortar, and is driven by the lateral movement mechanism to move laterally in the area covered by dry hard mortar.

[0026] The controller and main power supply in the control system are located in a control box outside the compaction device. Sensors are installed in the compaction mechanism to measure the travel position and contact pressure value of the compaction mechanism, converting the measurement data into signals and transmitting them to the controller. The controller receives the travel position and contact pressure signals and compares them with a preset contact pressure value. Based on the comparison result, the controller connects to the compaction mechanism via a switching circuit, coordinating the interaction between the main power supply and the compaction mechanism. The controller controls the compaction mechanism to compact and lift. Simultaneously, the compaction mechanism's built-in sensors automatically detect the travel position and feed it back to the controller until the comparison result shows that the contact pressure value equals the preset contact pressure value. Combining the automatically detected travel position signal, the controller locks the travel position of the compaction mechanism, continuously compacting the area covered by dry-hardened mortar at a constant preset contact pressure value. This achieves uniform compaction of the entire thickness of the dry-hardened mortar layer, reducing reliance on the operator's personal skills and fundamentally improving the construction quality and reliability of the floor base layer. The controller coordinates the interaction between the main power supply and the lateral movement mechanism, controlling the main power supply to provide power to the lateral movement mechanism. The lateral movement mechanism drives the compaction mechanism away from the original compaction area and moves laterally to other areas covered by dry-hard mortar to continue the compaction operation. This solves the problem of mechanization and intelligentization of compaction operations for small and medium-sized areas of dry-hard mortar.

[0027] Furthermore, such as Figures 1 to 3 As shown, the lateral movement mechanism includes a primary plate 1, a secondary plate 16, a tertiary plate 10, a primary drive assembly, and a secondary transmission assembly. The primary plate 1 and the secondary plate 16 are slidably connected, and the secondary plate 16 and the tertiary plate 10 are slidably connected. The primary drive assembly is disposed on the primary plate 1 and drives the secondary plate 16 to move laterally. The secondary transmission assembly is disposed on the secondary plate 16 and the tertiary plate 10, and the secondary plate 16 drives the tertiary plate 10 to move laterally through its lateral movement and the secondary transmission assembly. Through the lateral sliding connection of the primary plate 1, the secondary plate 16, and the tertiary plate 10, and the primary drive assembly and secondary transmission assembly, the lateral movement mechanism achieves the lateral movement operation where the primary plate 1 drives the secondary plate 16 to move laterally by a distance 'a', and the secondary plate 16 drives the tertiary plate 10 to move laterally by a distance '2a'.

[0028] Furthermore, such as Figures 1 to 3As shown, two primary parallel track assemblies 17 are provided on the other side of the primary plate 1. Each primary track assembly 17 includes a primary track and a primary slider, which are slidably connected to the primary track. A rack 2 is provided on one side of the secondary plate 16, and two secondary parallel track assemblies 21 are provided on the other side of the secondary plate 16. Each secondary parallel track assembly 21 includes a secondary track and a secondary slider, which are slidably connected to the secondary track. The primary plate 10 and the secondary plate 16 are slidably connected by a fixed connection between the secondary plate 16 and the primary slider, and the tertiary plate 10 and the secondary plate 16 are slidably connected by a fixed connection between the tertiary plate 10 and the secondary slider. The primary parallel track assemblies 17 and 21 enable a lateral sliding connection between the primary plate 1 and the secondary plate 16, and a lateral sliding connection between the secondary plate 16 and the tertiary plate 10.

[0029] Furthermore, such as Figures 1 to 3 As shown, the primary drive assembly includes a transverse motor 4, a gear 5, and an L-shaped mounting base 3. The vertical side of the L-shaped mounting base 3 is fixed to one side of the primary plate 1, and the horizontal plate of the L-shaped mounting base 3 extends to the other side of the primary plate 1. The transverse motor 4 is fixed to the vertical plate of the L-shaped mounting base 3. The gear 5 is connected to the drive shaft of the transverse motor 4 via a key, and the gear 5 meshes with the rack 2. The primary drive assembly consists of the gear 5, which is keyed to the drive shaft of the transverse motor 4. The gear 5 rotates on the rack 2, driving the secondary plate 16, which is fixed to the rack 2, to move laterally. The forward and reverse rotation of the transverse motor 4 determines the left and right direction of the secondary plate's lateral movement.

[0030] Furthermore, such as Figures 1 to 3 As shown, the secondary transmission assembly includes a transmission belt 6, rollers 7, fixed shafts 8, an upper clamping plate 14, and a lower pressure plate 15. The two fixed shafts 8 are fixed to the upper ends of the secondary plate 16, and the two rollers 7 are respectively inserted into the two fixed shafts 8. The transmission belt 6 covers the rollers 7 at both ends. The upper clamping plate 14 is fixed to the top surface of the tertiary plate 10. The upper belt of the transmission belt 6 is clamped in the upper clamping plate 14. The lower pressure plate 15 is fixed to the horizontal plate of the L-shaped fixed seat 3, and the lower belt of the transmission belt 6 is clamped between the lower pressure plate 15 and the horizontal plate of the L-shaped fixed seat 3. The secondary plate 16, which is fixed on the primary plate 1, moves laterally by a distance 'a', thereby causing the secondary plate 16 to slide laterally with the tertiary plate 10, and thus causing the tertiary plate 10 to move laterally by a distance 'a'. In the secondary transmission assembly, the transmission belt 6 is clamped by the upper clamping plate 14 located on the top surface of the tertiary plate 10, the lower pressure plate 15 fixed on the other side of the primary plate 1, and the horizontal plate of the L-shaped fixing seat 3, thereby causing the transmission belt 6 fixed on the secondary plate 16 and the roller 7 to drive the tertiary plate 10 to move laterally by a distance 'a'. Thus, the secondary plate 16 is driven by the primary drive assembly and the secondary transmission assembly to move the tertiary plate 10 laterally by a distance '2a'.

[0031] Furthermore, such as Figures 1 to 3As shown, the compaction mechanism includes a protective cover 9, a lifting and pressing component, a flat pressing component, and an upper mounting base 13. The lifting and pressing component is hinged at both ends to the three-stage plate 10 and the protective cover 9, respectively. The upper mounting base 13 is fixed to the upper clamping plate 14. The lifting and pressing component is hinged to the three-stage plate 10 via the upper mounting base 13. The flat pressing component is disposed inside the protective cover 9, and the protective cover 9 is slidably connected to the three-stage plate 10. The slidable connection between the three-stage plate 10 and the protective cover 9 enables the three-stage plate 10 to drive the protective cover 9 to move laterally. The lifting and pressing component, hinged between the protective cover 9 and the three-stage plate 10, enables vertical relative movement between the protective cover 9 and the three-stage plate 10. The flat pressing component, disposed inside the protective cover 9, performs the compaction operation of the dry-hardened mortar floor as the protective cover 9 moves vertically.

[0032] Furthermore, such as Figures 1 to 3 As shown, guide grooves are provided on both sides of the protective cover 9, and guide rails are provided on both sides of the three-stage plate 10. The protective cover 9 and the three-stage plate 10 are slidably connected up and down within the guide grooves via the guide rails. Specifically, the sliding connection between the protective cover 9 and the three-stage plate 10 is an up-and-down sliding connection. Figures 2 to 3 As shown, two springs 11 are installed on the inner step shaft of the protective cover 9 and the three-stage plate 10. When the protective cover 9 slides downward relative to the three-stage plate 10, the springs 11 exert a downward compressive force on the dry hard mortar during compaction. After the dry hard mortar compaction is completed, the protective cover 9 slides upward relative to the three-stage plate 10. At this time, the compressed springs 11 bounce up, giving the protective cover 9 an upward lifting force, thus helping the protective cover 9 to rise.

[0033] Furthermore, such as Figures 1 to 3 As shown, the lifting and pressing assembly is an electric actuator 12. A lower pin mounting hole 22 is provided on the top panel of the protective cover 9. One end of the upper mounting base 13 is fixed to the upper clamping plate 14, and the other end of the upper mounting base 13 is an upper pin mounting hole. The upper end of the electric actuator 12 has a through-hole for the upper pin, and the lower end of the electric actuator 12 has a through-hole for the lower pin. The upper end of the electric actuator 12 is hinged to the upper mounting base via a pin passing through the upper pin hole and the upper pin mounting hole. The lower end of the electric actuator 12 is hinged to the top panel of the protective cover 9 via a pin passing through the lower pin hole and the lower pin mounting hole 22. The lifting and pressing assembly is the electric actuator 12, which is controlled by a controller to extend and retract to lift and press the protective cover 9.

[0034] Furthermore, such as Figures 1 to 3As shown, the flat pressing assembly includes a power roller 20, a middle support plate 19, and a track 18. Two pairs of mounting holes for the power roller 20 are provided on the front panel of the protective cover 9 corresponding to the back of the guide groove. Two pairs of mounting holes for the middle support plate 19 are provided on the front panel of the protective cover 9 corresponding to the rear panel. The power roller 20 is fixed inside the protective cover 9 by passing its shaft through the mounting holes. The middle support plate 19 is fixed inside the protective cover 9 by passing its shaft through the mounting holes. The track 18 covers the power rollers 20 on both sides. The lower surface of the middle support plate 19 is close to the lower track of the track 18. The two ends of the middle support plate 19 are rounded, and the two ends of the middle support plate 19 are secured between the two power rollers 20 by the rounded arcs. In the flat pressure component, the power roller 20, the middle support plate 19, and the track 18, the middle support plate 19 transmits the pressure to the dry hard mortar ground, the track 18 flattens and polishes the dry hard mortar ground, and the power roller 20 assists the third-level plate 10 to move laterally, thereby driving the protective cover 9 to move laterally.

[0035] Furthermore, such as Figures 1 to 3 As shown, the two sensors include a first sensor and a second sensor. The first sensor is disposed inside the electric actuator 12, detecting the stroke position of the electric actuator and transmitting the stroke position signal to the controller. The second sensor is disposed inside the middle support plate 19, detecting the pressure value borne by the middle support plate 19 and transmitting the pressure value signal to the controller. The controller is a single silicon chip, which is configured with multiple contact pressure values ​​B. The single silicon chip receives the stroke position signal transmitted by the first sensor and controls the electric actuator to press down and lift up by controlling the main power supply according to the stroke position signal. The single silicon chip receives the pressure value signal transmitted by the second sensor, converts the pressure value signal into a corresponding pressure value A, and compares the pressure value A with the contact pressure value B until the contact pressure value A is equal to the set contact pressure value B. At the same time, according to the stroke position signal, the controller locks the stroke position of the electric actuator 12, keeping the middle support plate 19 continuously pressed down. The set contact pressure value B is set according to the different characteristics of dry-hardened mortars produced by different manufacturers.

[0036] Working principle: This invention compacts a leveled, dry-hardened mortar surface. The main power is turned on, causing the traversing mechanism to move to a specific area within the dry-hardened mortar coverage zone. The electric push rod 12 in the compaction mechanism pushes the protective cover 9, causing the flattening components (including tracks 18, a central support plate 19, and a power roller 20) located within the protective cover 9 to move downwards until the central support plate 19, through the tracks 18, has a certain contact pressure value A with the dry-hardened mortar surface. The contact pressure value B is set according to the different characteristics of dry-hardened mortar produced by different manufacturers. During implementation, a second sensor built into the central support plate 19 measures the real-time contact pressure value A and sets the contact pressure value B. The second sensor converts the measured real-time contact pressure value A into a signal and transmits it to the single silicon wafer. The single silicon wafer receives the signal from the second sensor and compares the real-time contact pressure value A with the internally set contact pressure value B. When the contact pressure value A B, the single silicon wafer controls the main power supply to shut off. The control actuator 12 transmits pressure to the central support plate 19 inside the protective cover 9 through extension and retraction, causing the central support plate 19 to continuously displace relative to the ground in the vertical direction. This ensures that the real-time contact pressure value A of its built-in second sensor equals the set contact pressure value B, thus guaranteeing that the force used to compact the ground is constant. The single silicon wafer receives the stroke position signal detected in real-time by the first sensor located inside the actuator 12. Based on the stroke position signal and the real-time contact pressure value A = the set contact pressure value B, it locks the stroke position of the actuator 12, ensuring that the compacted ground is continuously pressurized at a constant value. The compaction and covering of the dry-hardened mortar area is achieved through a lateral movement mechanism. The single silicon wafer coordinates the main power supply and the transverse motor 4 in synergy. The single silicon wafer switches the main power supply to provide power to the transverse motor 4, enabling its rotation. The rotation of the transverse motor 4 drives the gear 5, which is keyed to the drive shaft, to rotate. Gear 5 meshes with rack 2, causing it to rotate on rack 2, thus driving the secondary plate 16, which is fixed to rack 2, to move laterally. The forward and reverse rotation of the transverse motor 4 determines the left and right direction of the secondary plate's transverse movement. The lateral motor 4 drives the secondary plate 16 to move laterally a distance 'a', thereby connecting the secondary plate 16 laterally to the tertiary plate 10, causing the tertiary plate 10 to move laterally a distance 'a'. In the secondary transmission assembly, the transmission belt 6 is clamped by the upper clamping plate 14 located on the top surface of the tertiary plate 10, the lower pressure plate 15 fixed to the other side of the primary plate 1, and the horizontal plate of the L-shaped fixing seat 3. This causes the transmission belt 6, fixed to the secondary plate 16, and the roller 7 to drive the tertiary plate 10 laterally a distance 'a', resulting in the secondary plate 16 moving laterally a distance 2a, driven by the primary drive assembly and the secondary transmission assembly. This achieves coverage of a lateral travel area twice the width of the vehicle body. Throughout the pressing and lateral movement process, the protective cover 9 continuously drives the track 18 to rub and polish the ground. The integrated coordinated movement of pressing, lateral coverage, and track 18 friction completes the compacted, flat, and dry-hardened mortar surface coverage construction.
