Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to an integrated vibratory compaction and leveling machine for factory floor construction. Background Technology

[0002] As the basic structure of industrial production sites, factory floors play a crucial role in supporting production equipment, ensuring the safety of personnel, and facilitating smooth logistics. The quality of their construction directly affects the subsequent performance and lifespan of the factory building. During the concrete construction of factory floors, concrete vibration and surface smoothing are core and critical processes. To improve construction efficiency and quality, specialized construction equipment capable of integrating multiple processes is needed.

[0003] In current factory floor construction, the operations related to support, vibration, and leveling are generally characterized by fragmentation, high reliance on manual labor, and insufficient vibration depth. Regarding equipment support methods, a common practice is to use wheeled graders or leveling vehicles to travel and operate directly on the already tied reinforcing bars. The equipment's own weight and vibration load are applied to the reinforcing bars through the tires, easily causing displacement of the reinforcing mesh, thinning of the protective layer, or even deformation and damage to the reinforcing bars. Furthermore, it is difficult to obtain stable and reliable support points between the reinforcing bars.

[0004] During vibration compaction, manual hand-held vibrators are often used to compact the concrete in small sections. Some projects supplement this with graders, but the vibration of graders is mainly concentrated on the surface of the concrete, making it difficult to effectively reach the deeper layers of concrete in the thickness direction. Deep air bubbles are not easily expelled, and the density cannot be guaranteed. Overall, vibration and leveling usually rely on two independent sets of equipment and multiple manual processes, with a lack of automatic linkage between the equipment. Existing "integrated" equipment still requires considerable manual intervention in deep vibration compaction, automatic material replenishment, and fine leveling, limiting construction efficiency and quality stability, and making it difficult to meet the high flatness requirements of modern industrial plants. Summary of the Invention

[0005] In order to improve the problems of existing floor construction equipment that easily damages steel bars, does not achieve dense compaction in deep vibration, cannot automatically handle local defects, and has low leveling accuracy, this application provides an integrated vibratory tamping and smoothing machine for factory floor construction.

[0006] The technical solution provided in this application for a vibratory compaction and leveling machine for factory floor construction is as follows: A vibratory compaction and leveling machine for factory floor construction includes: A portal frame system is used to span across the construction area and provide a mobile support platform; The vibratory compaction unit, suspended on the gantry frame system, is used to vibrate and compact the concrete. The leveling unit, suspended on the gantry frame system and located behind the vibratory feeding unit, is used to level the concrete surface after vibration.

At least one feeding bin is disposed above the plurality of vibrating rods, and its bottom is provided with a feeding port and a feeding solenoid valve; Multiple resistance sensors are installed one-to-one on multiple vibrating rods to detect the resistance of concrete to the vibrating rods in real time during the vibration process. The control system is electrically connected to multiple resistance sensors and the feeding solenoid valve, and is configured to: when the resistance value detected by any resistance sensor is lower than a preset threshold, determine that the corresponding area is a loose area, and control the feeding solenoid valve to open and feed concrete into the loose area.

[0007] Furthermore, the vibratory feeding unit also includes: Multiple displacement sensors are installed one-to-one on multiple vibrating rods to detect the depth of each vibrating rod inserted into the concrete in real time; The control system is also electrically connected to multiple displacement sensors and is configured to control each vibrator to stop at a preset insertion depth based on feedback from the displacement sensors.

[0008] Furthermore, the control system is also configured to dynamically adjust the vibration time of the corresponding vibrator based on the resistance value detected by the resistance sensor; the adjustment logic follows that the greater the resistance value, the longer the vibration time.

[0009] Furthermore, the portal frame system includes: The first telescopic leg and the second telescopic leg are arranged in pairs. Each telescopic leg includes an outer tube and an inner tube that can slide relative to each other and are driven to extend and retract by a vertical hydraulic cylinder. The support beam is rigidly connected to the top of each telescopic leg; An electronic level is installed on the crossbeam of the support frame to detect its levelness; The control system is electrically connected to the electronic level and each of the vertical hydraulic cylinders, and is configured to control the action of each vertical hydraulic cylinder based on the feedback from the electronic level, so as to automatically adjust the support beam to a horizontal state.

[0010] Furthermore, the support beam is provided with a transversely extending beam track, and the gantry support system also includes a mother beam slidably assembled in the beam track, and a first telescopic beam and a second telescopic beam slidably nested at both ends of the mother beam. The first telescopic beam and the second telescopic beam are used to extend or retract synchronously under the drive of the transverse telescopic hydraulic cylinder to adjust the transverse span of the gantry support system.

[0011] Furthermore, the vibratory feeding unit is suspended below the first and second telescopic beams via a steering shaft, which is a telescopic structure to adapt to changes in the span of the first and second telescopic beams; the leveling unit is suspended below the middle of the steering shaft.

[0012] Furthermore, the leveling unit includes: The connecting plate is fixed to one side of the steering wheel and is positioned opposite to the vibrator. The connecting plate is hinged to the side of the connecting plate away from the steering wheel. The two are adjusted by multiple coarse adjustment telescopic rods to adjust the flipping posture of the connecting plate on the connecting plate. The top of the scraper plate is hinged to the side of the connecting plate away from the connecting plate, and the two are connected by multiple fine-tuning telescopic rods to adjust the flipping posture of the scraper plate on the connecting plate. At least two height sensors are installed at both ends of the scraper plate to detect the distance between the scraper plate and the concrete surface in real time. The control system is electrically connected to multiple telescopic rods and the height sensor, and is configured to independently control the extension and retraction of each telescopic rod based on the distance signal fed back by the height sensor, so as to dynamically adjust the contact pressure and posture between the scraper plate and the concrete surface.

[0013] Furthermore, the leveling unit also includes an elastic pressing device disposed above the scraper plate, used to provide a predetermined downward pressure to the scraper plate so that it remains in contact with the concrete surface.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. The integrated machine of this application achieves precise and automated positioning through the optimized design of the gantry support system: it adopts a "vertical hydraulic drive system + multi-stage telescopic column" to adjust the height of the telescopic legs, and coordinates with the electronic level of the top beam to calibrate the levelness in real time and automatically correct deviations to ensure the stability of the support; at the same time, relying on "nested telescopic beams + horizontal synchronous control valves", the telescopic beams extend synchronously to adapt to the width of the construction area, solving the problems of low accuracy and poor efficiency of traditional manual positioning, and improving the positioning efficiency and accuracy of the support. 2. The vibration system of the integrated machine in this application constructs an adaptive vibration and vibration-replenishment collaborative mode: with a hydraulically synchronously controlled vibrating rod matrix as the core, combined with displacement sensors to accurately control the vibration depth, avoiding missed vibration and over-vibration; by detecting the concrete resistance through resistance sensors, the vibration time is automatically adjusted (extended when the resistance is high, shortened when the resistance is low) to achieve adaptive vibration; when a loose area is detected, the replenishment bin is triggered to automatically replenish material and vibrate synchronously, solving the problem that traditional equipment cannot simultaneously take into account deep compaction and automatic replenishment, thus improving the vibration quality and efficiency; 3. The leveling system of the integrated machine in this application adopts a dynamic and precise adjustment design: height sensors, preferably infrared distance sensors, are set at both ends of the scraper plate to detect the distance to the ground in real time and transmit it to the central control system; it is equipped with an elastic pressing device to ensure the fit, and is adjusted in linkage through hydraulic telescopic rods: the telescopic rods are shortened to flatten the raised areas and extended to guide the filling in the concave areas, breaking through the reliance on traditional manual experience and significantly improving the flatness of the leveling. 4. The integrated machine of this application realizes the integrated operation of "support-vibration-filling-leveling": the gantry frame, vibration, filling and leveling system are integrated into the same equipment. The systems work together through mechanical, hydraulic and electrical linkage (vibration and filling are carried out after the frame is positioned, and then the leveling mode is automatically switched). This reduces manual intervention and process connection time, solves the problems of low efficiency and unstable quality of traditional decentralized operation, realizes automated integrated construction, and improves the overall efficiency and quality stability.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] Reference Figure 1 , Figure 2 and Figure 3 This application discloses an integrated vibratory compaction and leveling machine for factory floor construction, comprising: A portal frame system is used to span across the construction area and provide a mobile support platform.

[0022] The vibratory compaction unit, suspended on the gantry frame system, is used to vibrate and compact the concrete. The leveling unit, suspended on the gantry frame system and located behind the vibratory feeding unit, is used to level the surface of the vibrated concrete. The vibratory feeding unit includes: Multiple vibrating rods 18 are arranged in a matrix; the diameter of the vibrating rods 18 is 30-50mm, the effective length is 500-800mm, and the longitudinal and transverse spacing is 250-350mm, so that a basic full coverage arrangement is formed within the width of the floor pouring; the insertion depth of the vibrating rods 18 is controlled at 80%-100% of the design thickness of the floor.

[0023] At least one feed bin 5 is positioned above multiple vibrating rods 18, and its bottom is equipped with a feed inlet 24 and a feed solenoid valve 25. The feed bin 5 is preferably a closed box structure with a cuboid upper part and an arc-shaped chute structure that curves and contracts to one side at the bottom, its length being approximately the same as the width of the vibrating matrix. The lower arc-shaped feed section of the feed bin 5 has a feed inlet on its side wall, and the feed solenoid valve 25 is installed at the feed inlet 24 to control the opening and closing of the feed inlet 24, guiding the concrete in the bin to the area above the vibrating matrix.

[0024] Multiple resistance sensors 27 are installed at the ends of multiple vibrating rods 18 in a corresponding manner. They are used to measure the resistance of concrete to the vibrating rods 18 in real time during the vibration process, providing parameter basis for subsequent adaptive vibration and material replenishment control.

[0025] The control system is electrically connected to multiple resistance sensors 27 and a feeding solenoid valve 25, and is configured to: when the resistance value detected by any resistance sensor 27 is lower than a preset threshold, determine that the corresponding area is a loose area, and control the feeding solenoid valve 25 to open and add concrete material to the loose area.

[0026] Specifically, refer to Figure 1 and Figure 2 The vibratory feeding unit also includes: Multiple displacement sensors 26 are installed one-to-one on multiple vibrating rods 18 to detect the depth of each vibrating rod 18 inserted into the concrete in real time. The control system is also electrically connected to multiple displacement sensors 26 and is configured to control each vibrator 18 to stop at a preset insertion depth based on feedback from the displacement sensors 26.

[0027] Furthermore, the control system is configured to dynamically adjust the vibration time of the corresponding vibrating rod 18 based on the resistance value detected by the resistance sensor 27; the adjustment logic follows the principle that the greater the resistance value, the longer the vibration time.

[0028] In addition, the portal frame system includes: The system consists of a first telescopic leg 3 and a second telescopic leg 4 arranged in pairs. Each telescopic leg includes an outer tube and an inner tube that can slide relative to each other, and is driven to extend and retract by a vertical hydraulic cylinder. When the vertical hydraulic cylinder is filled with oil, the piston rod pushes the inner tube to extend axially along the outer tube, thereby adjusting the height of the telescopic leg. When the vertical hydraulic cylinder is de-oiled, the inner tube retracts into the outer tube under its own weight, thus retracting the telescopic leg. The lower end of the outer tube of each telescopic leg is fixed to a rectangular support plate 2 by welding. The lower surface of the support plate 2 can be equipped with an anti-slip pad or an adjustable base to increase friction with the ground and accommodate minor height differences in the base layer. A drive wheel 1 is installed below the support plate 2 on the side closer to the direction of construction.

[0029] The support beam 9 is rigidly connected to the top of each telescopic leg; An electronic level 23 is mounted on the support beam 9 and is used to detect its levelness. The control system is electrically connected to the electronic level 23 and each vertical hydraulic cylinder, and is configured to control the action of each vertical hydraulic cylinder according to the feedback of the electronic level 23, so as to automatically adjust the support beam 9 to a horizontal state.

[0030] Furthermore, the support beam 9 is provided with a transversely extending beam track 10. The portal frame system also includes a mother beam 16 slidably assembled in the beam track 10, and a first telescopic beam 11 and a second telescopic beam 15 slidably nested at both ends of the mother beam 16. The first telescopic beam 11 and the second telescopic beam 15 are used to extend or retract synchronously under the drive of the transverse telescopic hydraulic cylinder to adjust the transverse span of the portal frame system, thereby providing a portal support platform that spans the ground reinforcement mesh for the vibratory feeding system and the leveling system.

[0031] The vibratory feeding unit is suspended below the first telescopic beam 11 and the second telescopic beam 15 via a steering shaft 17. The steering shaft 17 is telescopic to accommodate changes in the span of the first telescopic beam 11 and the second telescopic beam 15. The leveling unit is suspended below the middle of the steering shaft 17. Specifically, both ends of the steering shaft 17 are respectively inserted into lifting rings 12 below the first telescopic beam 11 and the second telescopic beam 15, and a steering wheel 22 is welded and fixed to the middle of the steering shaft 17. Furthermore, one of the lifting rings 12 is equipped with a switching drive motor for driving the steering shaft 17 to rotate. By driving the steering shaft 17 to rotate via the switching drive motor, the vibratory feeding unit and the leveling unit on the steering shaft 17 can rotate synchronously, thereby realizing the switching between the vibratory feeding function and the leveling function.

[0032] Furthermore, each vibratory rod 18 is connected to a telescopic drive cylinder. The cylinder body of the telescopic drive cylinder is fixed to the steering wheel 22 by a mounting plate. The stroke of the telescopic cylinder is preferably 200-300mm, which is used to drive the vibratory rod 18 to extend and retract synchronously along the length of the vibratory rod 18. The aforementioned displacement sensor 26 is installed on the outermost telescopic rod of the vibratory rod 18 and extends or retracts with the vibratory rod 18. It is used to detect the extension length of the corresponding vibratory rod 18 relative to the mounting plate in real time, thereby determining the depth of the vibratory rod 18 inserted into the concrete.

[0033] In addition, refer to Figure 1 and Figure 3 The leveling unit includes: The connecting plate 21 is fixed to one side of the steering wheel 22 and is positioned opposite to the vibrator 18; The connecting plate 20 is hinged to the side of the connecting plate 21 away from the steering wheel 22. The two are adjusted by multiple coarse adjustment telescopic rods 8 to adjust the flipping posture of the connecting plate 20 on the connecting plate 21. The scraper plate 6 is preferably a long rectangular steel plate with a length of 4 to 6 m and a width of 300 to 400 mm. Its bottom working surface is processed into a slightly curved or slightly inclined scraping surface to reduce the frictional resistance between it and the concrete and to facilitate the movement of the concrete to the low-lying area. Its top is hinged to the side of the connecting plate 20 away from the connecting plate 21, and the two are connected by multiple fine-tuning telescopic rods 19 to adjust the flipping posture of the scraper plate 6 on the connecting plate 20. At least two height sensors 13 are set at both ends of the scraper plate 6 to detect the distance between the scraper plate 6 and the concrete surface in real time. Specifically, two connecting rods 14 perpendicular to the connecting plate 21 are fixed on the connecting plate 21. The height sensors 13 are respectively installed on the top of the two connecting rods 14 and pass through the connecting plate 21 to point to the concrete working area. The height sensors 13 can be infrared distance sensors.

[0034] The control system is electrically connected to multiple coarse-adjustment telescopic rods 8, multiple fine-adjustment telescopic rods 19, and a height sensor 13, and is configured to independently control the extension and retraction of each telescopic rod based on the distance signal fed back by the height sensor 13, so as to dynamically adjust the contact pressure and posture between the scraper plate 6 and the concrete surface.

[0035] The control system is also configured as follows: After completing the vibration operation at the current work station, control the telescopic legs to drive the vibration feeding unit to rise and control the switching drive motor to drive the steering shaft 17 to rotate, so that the vibration feeding unit flips forward and detaches from the concrete surface; then control the switching drive motor to drive the steering shaft 17 to rotate so that the leveling unit flips to align with the concrete floor, and then control the telescopic legs to drive the leveling unit to descend to the working position to perform the leveling operation.

[0036] Therefore, when using the all-in-one machine of this application for floor construction, refer to Figure 1 , Figure 2 and Figure 3 The following tasks can be performed in sequence.

[0037] Step 1: Positioning Operation of the Gantry Support System The vertical height is precisely adjusted by starting the vertical hydraulic drive system of the main control panel of the equipment. The hydraulic pump supplies oil to the vertical hydraulic cylinders in the first telescopic leg 3 and the second telescopic leg 4 of the gantry bracket. The piston rod pushes the sub-column to extend vertically along the main column. The operator controls the telescopic leg to extend to the height specified in the ground construction design by using the height data displayed on the main control panel. The anti-slip pad at the bottom of the main column increases the friction with the ground to prevent the bracket from sliding.

[0038] After the telescopic legs are close to the design height, the integrated electronic level 23 at the midpoint of the support beam 9 detects the levelness of the support beam 9 in real time. If the support beam 9 on one side is too high or too low, the control system automatically adjusts the extension and retraction of the corresponding telescopic leg cylinder until the electronic level 23 displays "level", ensuring that the support as a whole is in a stable and level state.

[0039] The lateral span is adapted to the construction area operation lateral telescopic control system. Hydraulic oil enters the hydraulic cylinders of the first telescopic beam 11 and the second telescopic beam 15 at the top through the synchronous control valve, pushing the first telescopic beam 11 and the second telescopic beam 15 to extend horizontally from the inner cavity of the parent beam 16 section. During the telescopic process, the extension amount can be observed through the length scale on the side of the telescopic beam, or it can be stopped by the limit switch at the port of the parent beam 16, so that the lateral span of the telescopic beam is completely matched with the width of the factory floor construction area.

[0040] Step 2: Operation of the concrete vibration system Once the concrete for the factory floor has been poured into the formwork, start the vibration system and proceed with the following steps.

[0041] 1. Precise positioning of the vibratory tamper using an 18-matrix matrix: The hydraulic synchronization control system is activated via the central control console. This system drives the telescopic cylinders at the top of the vibrating rods 18, causing all vibrating rods 18 to extend and retract synchronously along their length. Displacement sensors 26 at the top of each vibrating rod 18 provide real-time feedback on the extension length to the central control console until the vibrating rod 18 is inserted into the concrete to the same depth as the designed floor thickness, achieving full coverage of the pouring section. In this embodiment, the vibrating rods 18 have a diameter of 40mm, a longitudinal and transverse spacing of 300mm, and an insertion depth controlled at 80%–100% of the designed floor thickness to ensure complete coverage and vibration of the entire pouring section.

[0042] 2. Adaptive vibration: The vibration motor in the middle of the vibrator 18 is started, and at the same time, the resistance sensor 27 on the outer wall of the vibrator 18 detects the resistance of the concrete to the rod in real time. If the resistance is high, the control system automatically extends the vibration time in that area to ensure the deep concrete is compacted; if the resistance is low, it automatically shortens the vibration time to avoid aggregate segregation, thus achieving adaptive adjustment.

[0043] 3. Vibration-feeding synergy: If the resistance sensor 27 detects that the resistance in a certain area is abnormally low, it immediately sends a signal to the central control console, triggering the opening of the feeding solenoid valve 25 of the feeding hopper fixed above the vibration matrix. Fine aggregate concrete slides down the arc-shaped ramp through the feeding port 24 to the vibration operation area. During the feeding process, the vibrator 18 vibrates continuously to ensure that the feeding material is fully mixed and compacted with the original concrete. If the concrete compaction is normal, only conventional vibration is performed, and no feeding is required.

[0044] 4. Simultaneous retraction and status switching of vibrating rod 18: After the vibration reaches the standard, the vibration motor is turned off. After the vibration of the rods stops completely, the hydraulic synchronous control system drives the oil cylinder to retract, which drives all the vibrating rods 18 to retract slowly and synchronously. At the same time, the steering mechanism with the steering shaft 17 and steering wheel 22 as the core is started, which drives the vibrating rods 18 to slowly rotate from the vertical vibration state and gradually lift them to the horizontal state, detaching them from the concrete surface, making room for subsequent leveling operations.

[0045] Step 3: Floor leveling system operation After the vibratory rod 18 is raised, the equipment automatically switches to the leveling system operation mode, as follows.

[0046] 1. The scraper plate 6 is in contact with the concrete surface. The steering mechanism continues to rotate, driving the long rectangular scraper plate 66 connected to its bottom closer to the concrete surface; the cylindrical elastic pressing devices evenly distributed on the top of the scraper plate 6 are compressed to generate downward pressure, making the scraper plate 6 fit tightly against the concrete surface, avoiding scraping deviation due to poor fit.

[0047] 2. Real-time detection and dynamic adjustment of uneven areas The height sensor 13 detects the distance between the scraper plate 6 and the floor surface in real time and transmits the data to the central control system: if the distance is too small, the control system shortens the corresponding telescopic rod, reduces the downward pressure of the scraper plate 6 and fine-tunes the angle to accurately flatten the raised part; if the distance is too large, the corresponding telescopic rod is extended to increase the downward pressure of the scraper plate 6 and guide the surrounding concrete to fill the depression and make up for the depression defect.

[0048] 3. Scrape and shape at a uniform speed The central control system controls the equipment to move at a constant speed along the longitudinal direction of the factory floor. The scraper plate 6 continuously "shaves and fills" the floor under dynamic adjustment. During the movement, the elastic pressing device maintains the fit of the scraper plate 6, and the telescopic rod corrects the angle in real time, so that the floor surface reaches the design flatness requirements and the scraping operation is completed.

[0049] Therefore, the integrated machine of this application achieves precise and automated positioning through the optimized design of the gantry support system: it adopts a "vertical hydraulic drive system + multi-stage telescopic column" to adjust the height of the telescopic legs, and coordinates with the electronic level 23 of the top beam to calibrate the levelness in real time and automatically correct deviations to ensure the stability of the support; at the same time, relying on the "nested telescopic beam + horizontal synchronous control valve", the telescopic beam extends synchronously to adapt to the width of the construction area, solving the problems of low accuracy and poor efficiency of traditional manual positioning, and improving the positioning efficiency and accuracy of the support.

[0050] The integrated machine of this application constructs an adaptive vibration and vibration-replenishment collaborative mode: with a hydraulically synchronously controlled vibrating rod matrix 18 as the core, combined with a displacement sensor 26 to precisely control the vibration depth, avoiding missed vibration and over-vibration; by detecting the concrete resistance through a resistance sensor 27, the vibration time is automatically adjusted (extended when the resistance is high, shortened when the resistance is low) to achieve adaptive vibration; when a loose area is detected, the replenishment bin is triggered to automatically replenish material and vibrate synchronously, solving the problem that traditional equipment cannot simultaneously take into account deep compaction and automatic replenishment, thus improving the vibration quality and efficiency.

[0051] Furthermore, the leveling system of the integrated machine of this application adopts a dynamic and precise adjustment design: height sensors 13, preferably infrared distance sensors, are set at both ends of the scraper plate 6 to detect the distance to the ground in real time and transmit it to the central control system; with the elastic pressing device to ensure the fit, the hydraulic telescopic rod is adjusted in linkage: the telescopic rod is shortened to flatten the raised area and extended to guide the filling in the concave area, breaking through the reliance on traditional manual experience and significantly improving the flatness of the leveling.

[0052] Moreover, the integrated machine of this application realizes the integrated operation of "support-vibration-filling-leveling": the gantry frame, vibration, filling and leveling system are integrated into the same equipment. The systems work together through mechanical, hydraulic and electrical linkage (vibration and filling are carried out after the frame is positioned, and then the leveling mode is automatically switched), which reduces manual intervention and process connection time, solves the problems of low efficiency and unstable quality of traditional decentralized operation, realizes automated integrated construction, and improves the overall efficiency and quality stability.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
