Description

TECHNICAL FIELD

[0001] The application belongs to the field of construction devices, and particularly relates to a polyurethane color ceramic pavement construction device. BACKGROUND

[0002] Under the background of rapid urbanization and the increasing demand for road landscape, polyurethane color ceramic pavement, as a kind of paving material with both aesthetics and functionality, has been widely used in urban slow system, square green space and characteristic road in recent years. However, the popularization and use of the material are limited by the inherent defects of traditional construction process, and it is urgent to realize the qualitative breakthrough through technological innovation.

[0003] The current construction of polyurethane color ceramic pavement still stays in the primary stage of manual operation as the main part and simple mechanical equipment as the auxiliary part. This traditional mode has some systemic defects that are difficult to overcome. In the crucial base treatment link, the conventional cleaning method is difficult to completely remove the road dust, resulting in the existence of isolation medium between the base and the adhesive layer, which directly affects the bonding effect of the two. In the core adhesive troweling process, the construction quality completely depends on the experience level of the operator. Since the fixed angle trowel used cannot be dynamically adjusted according to the actual situation of the road surface, when encountering local depressions or protrusions of the road surface, the problem of uneven troweling thickness is prone to occur. The adhesive in the depression is too thin, which may cause insufficient embedding of the aggregate, while the material accumulation in the protrusion will cause waste and uneven surface.

[0004] The precision loss of this basic process will also have a chain reaction. When the adhesive coating thickness is uneven, the subsequent color ceramic aggregate spreading process is difficult to achieve uniform distribution. In some areas, the aggregate is embedded too deeply due to the excessive thickness of the adhesive, while in other areas, the aggregate is not firmly attached due to the excessive thinness of the adhesive. This not only affects the visual aesthetics of the road surface, but also seriously weakens the durability and performance of the road surface. In addition, the traditional construction process is not closely linked, from base cleaning to adhesive troweling, to aggregate spreading and surface compaction, each link needs separate manual intervention and quality control, resulting in low construction efficiency and unstable quality.

[0005] With the increasing demand for refined construction in modern road construction, as well as the comprehensive pursuit of material utilization rate, construction efficiency and engineering quality, the traditional construction mode has obviously failed to meet market demand. Especially in urban renewal and road reconstruction projects, higher standards are required for construction precision, project progress and environmental friendliness, which urgently needs to develop a new type of construction device that can realize automation, digitization and continuous operation. Such a device should have the ability of real-time sensing, intelligent decision-making and precise execution, so as to fundamentally solve the problems of relying on manual experience, discrete process and large quality fluctuations in traditional process, and provide reliable technical support for the high-quality application of polyurethane color ceramic pavement. SUMMARY

[0006] The purpose of the present application is to solve the problems in the background art, and provide a quick-release floor system.

[0007] The above technical purpose of the present application is achieved by the following technical scheme: A polyurethane-based colored ceramic pavement construction device, comprising a walking frame and a dust suction head, a flatness detection sensor, a glue outlet, a colored ceramic uniform feeding mechanism and a spreading mechanism arranged in sequence along the walking direction of the walking frame, wherein the bottom of the glue outlet is provided with a glue outlet, and the glue outlet linear array has a plurality of hinged adjustable trowel mechanisms, the flatness detection sensor can adopt a laser sensor, and the number of the flatness detection sensor corresponds to the number of the hinged adjustable trowel mechanism.

[0008] The dust suction head of the present application can suck away the dust, and then the flatness detection sensor can accurately detect the height of the front road surface in advance, and transmit the data to the controller in real time, and the controller drives the hinged adjustable trowel mechanism to act, and through dynamic and independent fine adjustment of the elevation angle of each trowel, the glue gap below the trowel is changed in real time, which makes the system can automatically increase the glue amount to fill when encountering road surface depression, and reduce the glue amount to avoid material accumulation when encountering convex, so that the adhesive layer with extremely uniform thickness can be scraped on the bumpy base layer, not only the material is saved significantly, but also the subsequent aggregate embedding depth is ensured to be consistent, and finally a high-performance flat road surface is achieved, the aggregate is densely and uniformly laid on the accurately controlled glue layer, and the whole constitutes a continuous and intelligent digital construction system, which completely changes the traditional discrete operation mode relying on manual experience, and significantly improves the construction efficiency and material utilization rate while ensuring the engineering quality.

[0009] Preferably, the hinged adjustable trowel mechanism comprises a trowel body, a rotary motor, a rotary shaft, a passive gear, a driving rotary gear and a rotary block, the rotary motor is fixed at the bottom of the glue outlet, the rotary shaft is rotatably arranged at the bottom of the glue outlet, and the rotary block is fixed on the rotary shaft, the trowel body is fixedly connected with the rotary block, the passive gear is fixedly sleeved on the rotary shaft, the driving rotary gear is arranged at the output end of the rotary motor, and the driving rotary gear is engaged with the passive gear.

[0010] The driving rotary gear is driven by the rotary motor arranged at the bottom of the glue outlet, the rotary shaft and the rotary block fixedly connected with the passive gear are rotated, and the trowel body fixed on the rotary block is swung around the shaft, so that the trowel elevation angle is accurately adjusted by the transmission mechanism, the problems of low efficiency and insufficient precision caused by manual adjustment relying on manual experience in traditional construction are solved, the glue gap can be dynamically adjusted in real time according to the road surface condition, and the adhesive coating thickness is uniform and consistent.

[0011] The trowel of the present application can not only maintain its inherent troweling function, but also dynamically adjust the included angle with the base layer according to the road surface condition, effectively solving the process problems of uneven troweling thickness and out-of-control material distribution of the traditional fixed trowel when dealing with the ups and downs of the road surface, thereby ensuring the formation of a uniform thickness and smooth surface of the adhesive coating, and providing an ideal base surface for the uniform embedding of subsequent ceramic particles.

[0012] Preferably, the color ceramic uniform feeding mechanism comprises a rotating discharge cylinder, a material limiting cover and a color ceramic bin, the rotating discharge cylinder is rotatably arranged on the walking frame, the outer side wall of the rotating discharge cylinder is provided with a plurality of storage grooves along the axial direction, the storage grooves are arranged along the circumferential direction of the rotating discharge cylinder, the material limiting cover is arranged in a half-enclosed manner on the side of the rotating discharge cylinder, and the color ceramic bin is arranged on the top of the material limiting cover.

[0013] The present application adopts the cooperation structure of the rotating discharge cylinder with circumferential array storage grooves and the half-enclosed material limiting cover, utilizes the storage grooves to receive the quantified ceramic particles from the bin during rotation, and realizes uniform material falling by gravity after passing through the material limiting cover, effectively solving the problems of uneven distribution, local accumulation or absence of aggregates caused by traditional manual spreading or simple hopper feeding, thereby ensuring the continuous, equal and uniform coverage of color ceramic particles on the adhesive surface, and providing reliable guarantee for forming color ceramic pavement with consistent color and dense structure.

[0014] Preferably, the material limiting cover comprises a top plate, a right side plate, a left side plate, a front plate, a rear plate and a scissor structure, the top plate, the right side plate, the left side plate, the rear plate and the front plate form a material falling area, the scissor structure is composed of first and second scissor links connected in series at the head and tail, the scissor structure is arranged on the inner side wall of the right side plate, and the tail end of the scissor structure is connected with the front plate.

[0015] The present application sets the scissor structure between the front plate and the right side plate, so that the material limiting cover can flexibly adjust the opening width of the material falling area according to the construction requirements, thereby accurately controlling the transverse spreading range according to different road widths, solving the problems of material waste or uneven spreading caused by the fixed material falling width of traditional equipment, realizing the accurate adaptation to different construction scenes, and effectively ensuring that the color ceramic particles can obtain uniform and consistent distribution effect under various road width conditions.

[0016] Preferably, an electric sliding rail is arranged below the side wall of the right side plate, a scraper is arranged on the electric sliding rail, and the scraper is tightly attached to the groove surface of the storage groove of the rotating discharge cylinder.

[0017] The scraper of this invention can automatically reciprocate along the axial direction of the discharge cylinder to clean the ceramic particles through mechanical scraping, causing the ceramic particles to accumulate in one position and ensuring that there are no ceramic particles at the end of the storage tank, thus ensuring that ceramic particles are evenly distributed in each storage tank.

[0018] Preferably, the leveling mechanism includes a pressure plate, a guide plate, a sliding member, and a drive assembly. The guide plate is fixed on the vehicle frame and has two guide rings distributed vertically on the guide plate. The sliding member is slidably disposed within the guide rings. The drive assembly includes a rotating member and a connecting member that cooperates with the rotating member and is connected to the sliding member. When the rotating member rotates, it drives the sliding member to perform up-and-down reciprocating motion through the connecting member.

[0019] This invention drives the sliding component to make precise up-and-down reciprocating movements along the guide ring through the driving component, so that the pressure plate can continuously and controllably press the laid ceramic particles vertically, ensuring that the ceramic particles are vertically embedded in the adhesive layer with uniform density, forming a flat and firm surface structure.

[0020] Preferably, the rotating component includes a disk, an eccentric shaft, and a drive motor. The output end of the drive motor is fixedly connected to the middle of the disk. The eccentric shaft is disposed on the disk, and the axis of the eccentric shaft is parallel to and does not coincide with the axis of the disk. The connecting component is a groove-shaped structure, and the eccentric shaft is slidably disposed within the groove-shaped structure.

[0021] This invention drives an eccentric shaft to move in a circular motion within a grooved connecting component by a drive motor, converting the rotary drive into the linear reciprocating motion of the sliding component. This solves the technical problems of large impact force and unstable motion trajectory in traditional paving mechanisms, thereby enabling the pressure plate to achieve high-frequency, uniform vertical vibration and pressure, ensuring that the ceramic particles and polyurethane adhesive are fully integrated to form a high-density, integrated, and stable road surface structure.

[0022] Preferably, an adjustable height defoaming roller is provided between the dispensing cylinder and the leveling mechanism. The adjustable height defoaming roller includes a roller body, a fixed plate, and an electric push rod. The fixed plate is located at both ends of the roller body. The roller body is rotatably located between the two fixed plates via bearings. The electric push rod is fixed to the rear side wall of the dispensing cylinder, and the push rod end of the electric push rod is fixedly connected to the fixed plate.

[0023] This invention controls the height of the defoaming roller off the ground by using an electric push rod, enabling the roller to apply stable pressure adaptively according to the coating thickness. This ensures that the polyurethane adhesive completes efficient defoaming before flattening, providing a dense and flat adhesive base layer for subsequent ceramic particle embedding.

[0024] Preferably, the roller body is a silicone roller, and the roller surface of the roller body is provided with continuous micro-annular grooves along the axial direction, with a groove width of 0.8~1.5mm, a groove depth of 0.3~0.8mm, a groove spacing of 2~5mm, and a rounded groove opening.

[0025] This invention employs a micro-annular grooved silicone roller with specific groove width, depth, and spacing to create an efficient micro-extrusion and release cycle during adhesive compaction. When the groove edges contact the adhesive surface, radial extrusion is applied to the air bubbles, pushing them to detach and break them. As the roller rotates, the groove cavities rapidly rebound due to the elasticity of the silicone at the moment of detachment from the adhesive layer, forming an instantaneous negative pressure zone. This zone draws deep residual microbubbles into the groove area for secondary breakage. This continuous dynamic dual mechanism of mechanical extrusion and negative pressure suction solves the process defect of traditional smooth rollers, which can only handle surface bubbles and cannot eliminate deep microbubbles. At the same time, the rounded groove structure avoids the damage of shear stress to the adhesive surface structure, achieving comprehensive and non-destructive defoaming of polyurethane adhesives from the surface to the depths.

[0026] The glue dispensing cylinder is equipped with several glue dispensing hoppers. The number of glue dispensing hoppers is the same as the number of hinged adjustable trowel mechanisms. The bottom of each glue dispensing hopper is equipped with a flow control valve. The traveling frame is also equipped with a glue mixing cylinder 40. The mixed glue is pumped into the glue dispensing hoppers by a pump. The glue dispensing hoppers correspond to one trowel body.

[0027] This invention constructs a zoned precision adhesive supply system by independently configuring an adhesive hopper with a flow control valve for each articulated adjustable trowel mechanism. This allows the adhesive supply amount of each trowel unit to be synchronously adjusted through the valve when adjusting its elevation angle to adapt to road surface undulations. This solves the problem of local adhesive supply lag and mutual interference caused by the fluid pressure equalization effect in traditional shared material chambers. As a result, a high degree of coordination between adhesive supply and scraping molding is achieved, ensuring the uniformity of adhesive layer thickness in each area even under complex road conditions.

[0028] The trowel body has baffles formed on both sides to prevent mutual interference in the glue supply.

[0029] In summary, the beneficial effects of this invention are as follows: 1. This invention uses a dust suction head to remove dust, and then a flatness detection sensor to accurately detect the height of the road surface ahead. The data is transmitted to the controller in real time, and the controller drives the articulated adjustable trowel mechanism to operate. By dynamically and independently fine-tuning the elevation angle of each trowel, the adhesive dispensing gap below it is changed in real time. This allows the system to automatically increase the amount of adhesive to fill the road surface depressions and reduce the amount of adhesive to avoid material accumulation when encountering bulges. As a result, an extremely uniform adhesive layer can be scraped even on uneven base surfaces. This not only significantly saves materials but also ensures that the subsequent aggregate embedding depth is consistent, ultimately achieving a high-performance flat road surface. The aggregate is laid densely and uniformly on the precisely controlled adhesive layer. The whole system constitutes a continuous, intelligent, digital construction system, which completely changes the traditional discrete operation mode that relies on manual experience. While ensuring project quality, it significantly improves construction efficiency and material utilization. 2. This invention uses a rotary motor located at the bottom of the glue dispensing cylinder to drive an active rotating gear, which in turn drives a rotating shaft and a rotating block fixed to the passive gear to rotate. This controls the trowel body fixed on the rotating block to swing around the shaft. This transmission mechanism enables precise electric adjustment of the trowel's elevation angle, solving the problems of low efficiency and insufficient precision caused by manual adjustment based on experience in traditional construction. It can dynamically adjust the glue dispensing gap in real time according to the road surface conditions, ensuring a uniform and consistent adhesive coating thickness. 3. This invention employs a rotating discharge cylinder with a circumferential array of storage troughs and a semi-enclosed material limiting cover. During rotation, the storage troughs receive a fixed amount of ceramic particles from the hopper, and after passing through the material limiting cover, gravity ensures uniform discharge. This effectively solves the problems of uneven aggregate distribution, local accumulation, or missing aggregate caused by traditional manual spreading or simple funnel feeding. As a result, it ensures that the colored ceramic particles achieve continuous, equal, and uniform coverage on the adhesive surface, providing a reliable guarantee for forming a colored ceramic pavement with consistent color and dense structure. 4. This invention drives an eccentric shaft to make circular motion within a grooved connecting component by driving a motor, converting the rotary drive into the linear reciprocating motion of the sliding component. This solves the technical problems of large impact force and unstable motion trajectory in traditional paving mechanisms, thereby enabling the pressure plate to achieve high-frequency, uniform vertical vibration and pressure, ensuring that the ceramic particles and polyurethane adhesive are fully integrated to form a high-density, integrated, and stable road surface structure.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example

[0035] like Figures 1-2 As shown, a polyurethane colored ceramic pavement construction device includes a walking frame 1 and a dust suction head 2, a flatness detection sensor 3, a glue dispensing cylinder 4, a colored ceramic uniform feeding mechanism 6, and a leveling mechanism 7 arranged sequentially along the traveling direction of the walking frame 1. A glue dispensing port 41 is provided below the glue dispensing cylinder 4, and a number of hinged adjustable trowel mechanisms 5 are arranged in a linear array at the glue dispensing port 41.

[0036] like Figures 3-5 As shown, the hinged adjustable trowel mechanism 5 includes a trowel body 51, a rotary motor 52, a rotary shaft 53, a driven gear 54, a driving rotary gear 55, and a rotating block 56. The rotary motor 52 is fixed to the bottom of the glue dispensing cylinder 4, the rotary shaft 53 is rotatably mounted on the bottom of the glue dispensing cylinder 4, the rotating block 56 is fixed on the rotary shaft 53, the trowel body 51 is fixedly connected to the rotating block 56, the driven gear 54 is sleeved and fixed on the rotary shaft 53, and the driving rotary gear 55 is located at the output end of the rotary motor 52, and the driving rotary gear 55 meshes with the driven gear 54.

[0037] like Figure 6 As shown, the glue dispensing cylinder 4 is provided with a number of glue dispensing hoppers 411. The number of glue dispensing hoppers 411 is the same as the number of hinged adjustable trowel mechanism 5. The bottom of the glue dispensing hopper 411 is provided with a flow control valve 412. The two sides of the trowel body 51 are formed with baffles 511.

[0038] like Figures 7-9 As shown, the colored ceramic uniform feeding mechanism 6 includes a rotating discharge cylinder 61, a limiting cover 62, and a colored ceramic hopper 63. The rotating discharge cylinder 61 is rotatably mounted on the traveling frame 1. A storage trough 611 is formed on the outer side wall of the rotating discharge cylinder 61 along the axial direction. Several storage troughs 611 are arranged in an array along the circumference of the rotating discharge cylinder 61. The limiting cover 62 is semi-enclosed on the side of the rotating discharge cylinder 61. The colored ceramic hopper 63 is located on top of the limiting cover 62. The limiting cover 62 includes a top plate 621. The right side plate 622, left side plate 623, front plate 624, rear plate 625, and scissor structure 626, together with the top plate 621, right side plate 622, left side plate 623, rear plate 625 and front plate 624, form a material dropping area 620. The scissor structure 626 is composed of fork-type connecting rods connected in series and hinged. The scissor structure 626 is located on the inner side wall of the right side plate 622. The end of the scissor structure 626 is connected to the front plate 624. An electric slide rail 628 is provided below the side wall of the right side plate 622. A scraper 627 is provided on the electric slide rail 626.

[0039] like Figures 10-11As shown, the leveling mechanism 7 includes a pressure plate 71, a guide plate 72, a sliding member 73, and a drive assembly 74. The guide plate 72 is fixed on the traveling frame 1. The guide plate 72 has two guide rings 721 distributed vertically. The sliding member 73 is slidably disposed within the guide rings 721. The drive assembly 74 includes a rotating member 741 and a connecting member 742 that cooperates with the rotating member 741 and is connected to the sliding member. When the rotating member 741 rotates, it drives the sliding member 73 to reciprocate up and down through the connecting member 742. The rotating member 741 includes a disc 7411, an eccentric shaft 7412, and a drive motor 7413. The output end of the drive motor 7413 is fixedly connected to the middle of the disc 7411. The eccentric shaft 7412 is disposed on the disc 7411. The axis of the eccentric shaft 7412 is parallel to and does not coincide with the axis of the disc 7411. The connecting member 742 is a groove-shaped structure, and the eccentric shaft 7412 is slidably disposed within the groove-shaped structure.

[0040] like Figures 12-13 As shown, an adjustable height defoaming roller 8 is also provided between the dispensing cylinder 4 and the leveling mechanism 7. The adjustable height defoaming roller 8 includes a roller body 81, a fixed plate 82, and an electric push rod 83. The fixed plate 82 is located at both ends of the roller body 81. The roller body 81 is rotatably located between the two fixed plates 82 through bearings. The electric push rod 83 is fixed on the rear side wall of the dispensing cylinder 4. The push rod end of the electric push rod 83 is fixedly connected to the fixed plate 82. The roller body 81 is a silicone roller. The roller surface of the roller body 81 has continuous micro-annular grooves 811 along the axial direction. The groove width is 0.8~1.5mm, the groove depth is 0.3~0.8mm, the groove spacing is 2~5mm, and the groove opening is rounded.

[0041] Working principle: such as Figures 1-13As shown, when the device starts working, the traveling frame 1 moves forward at a constant speed along the construction direction. The dust suction head 2 first uses negative pressure to adsorb dust and impurities from the base surface. Then, the flatness detection sensor 3 collects the road surface height in real time and transmits the data to the central controller. At the glue dispensing cylinder 4, the pre-mixed adhesive in the glue mixing cylinder 40 is injected into each glue dispensing hopper 411 by an independent delivery pump. The flow control valve 412 at the bottom of each glue dispensing hopper 411 adjusts its opening according to the control command. At the same time, the controller drives the active rotating gear 55 to mesh with the passive gear 54 through the rotary motor 52. The movement drives the rotating block 56 on the rotating shaft 53 to rotate, thereby precisely adjusting the elevation angle of the trowel body 51 (the angle formed between the scraping working surface (i.e. the bottom surface) of the trowel body (51) and the road surface). When a road surface depression is detected, the system synchronously increases the opening of the corresponding area flow control valve 412 and decreases the elevation angle of the trowel body 51, so that the adhesive can fully fill the depression through the increased glue outlet gap. When a road surface protrusion is encountered, the valve opening is reduced and the elevation angle is increased to suppress glue discharge. The baffles 511 on both sides of the trowel body 51 form a semi-closed cavity, which effectively prevents the crossflow interference of adhesive in adjacent areas. Subsequently, the silicone roller 81 with micro-annular grooves 811 of the defoaming roller 8 performs full-area defoaming treatment on the adhesive layer. The electric push rod 83 adjusts the height of the roller 81 in real time to maintain constant pressure. Then, the colored ceramic uniform feeding mechanism 6 starts to work. The storage tank 611 of the rotating discharge cylinder 61 quantitatively receives the aggregate in the limiting cover 62. After passing the limiting cover 62, it is evenly spread by gravity. The electric slide rail 626 drives the scraper 627 to move axially back and forth to prevent particle accumulation. Finally, the drive motor 7413 of the leveling mechanism 7 is connected to the structure via the eccentric shaft 7412. The sliding motion within the groove of component 742 transforms the rotational motion into the precise vertical reciprocating motion of the sliding component 73 within the guide ring 721. This motion drives the pressure plate 71 to apply high-frequency vibration and pressure to the aggregate, ensuring that the ceramic particles and adhesive form an integrated, dense structure. Ultimately, this results in a high-performance, smooth road surface. The precise control of the adhesive layer enables the dense and uniform laying of aggregates, forming a continuous and intelligent digital construction system. This system completely changes the traditional discrete operation mode that relies on manual experience, significantly improving construction efficiency and material utilization while ensuring project quality.
