Description

Technical Field

[0001] This invention relates to the technical field of construction equipment, and in particular to an assembled concrete vibration, smoothing, curing, and coating device. Background Technology

[0002] Concrete vibration, smoothing, curing, and coating are crucial processes for ensuring the strength, smoothness, and durability of concrete structures, playing a core role in ensuring project quality and extending the service life of structures during construction. However, improper operation in each stage can lead to minor issues such as surface honeycombing and unevenness deviations, or more serious problems such as structural cracks and insufficient strength, resulting in rework costs that are often 3-5 times higher than the initial construction. The root causes of these problems mainly include insufficient or excessive vibration depth, inaccurate machine control during smoothing, imbalanced temperature and humidity control during curing, and insufficient sealing of the coating (such as edge lifting or failure to repair damage in a timely manner). Traditional methods for addressing these problems include manual vibration, mechanical secondary grinding, extending the water curing time, and re-coating. Among these, manual vibration is highly flexible but the vibration effect is uneven and prone to omissions; mechanical secondary grinding can improve surface smoothness but can easily expose surface aggregates and affect structural integrity; extending water curing can improve strength development but significantly increases construction time and water consumption; re-coating is simple to operate but is prone to producing air bubbles and poor adhesion.

[0003] While intelligent concrete construction robots have emerged in recent years, achieving integrated operations of vibration, smoothing, curing, and coating, and possessing automatic movement and real-time quality monitoring capabilities, theoretically capable of dynamically adjusting construction parameters based on feedback from testing instruments, they still face the following technical bottlenecks in practical applications: First, the moving mechanism is prone to indentations or scratches on the working surface, which directly affects the flatness of the concrete surface.

[0004] Secondly, it is difficult to maintain continuous leveling during the dynamic grinding process, resulting in the flatness error of the concrete surface exceeding the specification requirements.

[0005] Third, the leveling area is fixed, which requires back-and-forth operation when dealing with large areas of cement flooring. This is not only inefficient, but also prone to causing defects to the uncured floor.

[0006] Traditional cement paving methods suffer from numerous technical bottlenecks and inefficiencies during construction. Firstly, the work mode relies heavily on manual, segmented operations, resulting in poor coordination between different processes and low overall construction efficiency. This is especially true in large-area paving scenarios, where continuous operation is difficult to achieve.

[0007] Secondly, the flatness control precision is insufficient, and the coordination between manual smoothing and mechanical vibration is poor, which easily leads to defects such as local height differences and wavy surfaces. These defects not only affect the appearance of the concrete surface, but also require additional costs for subsequent repairs of serious defects.

[0008] Third, the maintenance process lacks systematic control. Traditional water spraying maintenance methods are difficult to accurately control the temperature and humidity balance. Moreover, the mulching work is mostly done manually in the later stages, which can easily lead to problems such as poor film adhesion and failure of edge sealing. For large areas of concrete, workers inevitably need to enter the uncured concrete and leave footprints, which can cause quality problems such as cracking of the concrete surface and strength reduction.

[0009] Fourth, the existing equipment has a single function. Multiple machines are needed to work together to complete processes such as vibration, smoothing, curing, and film covering. The equipment transfer and debugging takes a long time, and repeated operations can easily cause secondary damage to the uncured cement surface, affecting the final paving quality. Summary of the Invention

It adopts a multi-end splicing work unit, which can control the width of the equipment according to the usage environment and complete the paving in a single pass; it uses a variable angle track slide for large-scale fine operation, uses a circular process for vibration and smoothing fine operation, and uses a tail smoothing device to eliminate possible indentations and scratches.

Detailed Implementation

[0028] Below, in conjunction with Figures 1 to 26 This invention provides a detailed description of an assembled concrete vibration, smoothing, curing, and coating device.

[0029] Depend on Figure 1 As shown, the assembled concrete vibration, smoothing, curing, and coating equipment of the present invention mainly consists of a traveling unit 1000, a tail smoothing section 2000, a central sliding platform 3000, and a tail sliding platform 4000. Workers assemble the equipment on-site, and the equipment autonomously completes concrete paving with the aid of cameras and lidar under the guidance of the operators.

[0030] like Figure 2As shown, the traveling unit 1000 includes two parallel traveling unit frames 1100, a drive unit 1200, and a track seat 1300. The traveling unit frame 1100 provides the basic framework for component installation. The drive unit 1200 is installed on the front and rear sides of the traveling unit frame 1100, controlling the movement of its front and rear rollers 1207, thereby controlling the movement of the entire device. The track seat 1300 is installed in the middle of the traveling unit frame 1100. A central slide 3000 is installed on the track 1309 between the two track seats 1300. A motor drives the track seats 1300 to move the track 1309 in a pitching motion, which assists the central slide 3000 in finely adjusting the position of the concrete paving surface to adapt to paving environments on slopes or curved surfaces. The following is a detailed description of the sub-parts of the traveling unit 1000: like Figure 3 As shown, the walking unit frame 1100 consists of a welded frame 1101, a front mounting plate 1102, an upper mounting plate 1103, a middle mounting plate 1104, a lower mounting plate 1105, a rear mounting plate 1106, a trail smoothing mounting plate 1107, a control box 1108, and a camera and lidar unit 1109. The welded frame 1101 is made of hollow steel and has holes for fixing the mounting plates and other equipment; each mounting plate is bolted to the corresponding holes in the welded frame 1101. The control box 1108 is bolted to the corresponding holes in the lower mounting plate 1105, and houses the main control components and power supply components. The camera and lidar unit 1109 is bolted to the upper mounting plate 1103, providing a field of view for the equipment's movement and assisting in control.

[0031] like Figure 4As shown, the drive unit 1200 includes a roller motor assembly 1201, a transmission rod 1202, a roller bracket 1203, roller bearings 1204, roller end caps 1205, synchronous pulleys 1206, and rollers 1207. The roller motor assemblies 1201 are mounted on the front mounting plate 1102 and the rear mounting plate 1106 respectively, providing torque to the rollers 1207 to drive the equipment. Different speeds are provided by the roller motor assemblies 1201 on both sides, creating a forward / reverse differential speed between the two units, thereby controlling the equipment's direction. The roller motor assembly 1201 includes a motor and a gear set. The motor's output shaft is connected to a small gear via a key, and a large gear is connected to the middle of the transmission rod 1202 via a key. The two gears mesh to transmit motor power to the synchronous pulleys 1206 on both sides of the unit. The roller bracket 1203 is mounted on the bottom of the welded frame 1101 and bears the main load. The roller bearing 1204 is installed in the mounting hole of the protruding part of the roller bracket 1203 and is used to support the transmission rod 1202 and the roller 1207. Its two sides are positioned by the roller end caps 1205. The synchronous pulleys 1206, which are respectively installed at both ends of the transmission rod 1202 and the roller 1207, are connected by belt drive. Secondary speed reduction can also be achieved through the belt drive mechanism. The roller 1207 reduces the contact pressure with the road surface, minimizing the formation of marks.

[0032] like Figures 5-9 As shown, the track base 1300 consists of a track base body 1301, a track base bearing 1302, a main disc 1303, a track base gear 1304, a worm gear shaft 1305, a shaft positioning cover 1306, a worm gear motor assembly 1307, a threaded mounting base 1308, and a track 1309. The track base body 1301 is mounted on the central hole of the intermediate mounting plate 1104 using coarse bolts, primarily bearing the weight and providing a reference for subsequent track base 1300 installation. The track base bearing 1302 is installed in the central hole on the vertical surface of the track base body 1301, reducing friction between the track and the base body during rotation. The main disc 1303 is installed within the bearing, and has a central threaded hole 1303a for connecting the disc. The two main discs 1303 are locked together using multiple bolts, the diameter of which is larger than the central hole on the vertical surface of the track base body 1301, thus securing the track base body 1301. The track seat gear 1304 drives the track to rotate, and a track seat gear positioning pin 1304a on it engages with the track seat gear positioning hole 1303b. The worm gear shaft 1305 is installed in a small hole at the upper end of the vertical surface of the track seat body 1301. The worm gear shaft 1305 has a shoulder and is positioned using a shaft positioning cover 1306.

[0033] The worm gear motor assembly 1307 is mounted on the upper mounting plate 1103. The motor directly drives the worm, which is locked in one direction to the worm wheel. The worm wheel drives a pinion to rotate coaxially. This pinion directly meshes with the track seat gear 1304, driving the track to pitch and rotate. A threaded mounting seat 1308 is mounted on the threaded mounting seat mounting hole 1303c, and its track mounting thread 1308a mates with the track 1309. The track 1309 has a fixed internal thread 1309a, which can be threadedly engaged with the threaded mounting seat 1308 for fixation. The two tracks 1309 are connected by a fixed external thread 1309b and a fixed internal thread 1309a. The track grooves 1309c on the track 1309 provide support for the lateral movement of the central slide 3000.

The trail smoothing motor assembly 2001, installed on the trail smoothing mounting plate 1107, provides power to drive the gear set at its end to rotate. This gear set drives the lifting rack 2002 to move up and down, thereby controlling the trail smoothing platform 2005, which is fixed at the bottom of the lifting rack 2002, to move up and down, and in turn controlling the smoothing device a 2007, which is installed at the bottom of the trail smoothing platform 2005, to move up and down.

[0035] Specifically, the wake smoothing platform 2005 includes an upper wake smoothing platform 2005a, a lower wake smoothing platform 2005b, and a wake smoothing rotating shaft 2005c. The upper and lower platforms can rotate around the shaft through the movable connection of the wake smoothing rotating shaft 2005c. The guide optical shaft 2003 can slide within the circular hole of the wake smoothing mounting plate 1107, and its lower end is fixed to the optical shaft seat 2004. The guide optical shaft 2003 is installed on the corresponding mounting hole of the wake smoothing platform 2005 to strengthen the support against torque. The pitch control motor 2006 is installed on the lower wake smoothing platform 2005b. The pitch control motor 2006 is connected to the upper wake smoothing platform 2005a through a linkage structure. With the help of this linkage structure, the pitch control motor 2006 controls the pitch angle of the smoother a2007 fixed below the lower wake smoothing platform 2005b. The trail smoothing posture detector 2008 is installed on the trail smoothing lower platform 2005b to detect the posture of the trail smoothing lower platform 2005b and feed it back to the control box 1108, thus constructing the trail smoothing control loop. Under the operation of this part of the structure, the processor outputs instructions to make the smoother a2007 fit as close as possible to the concrete surface to reduce the trails generated by the roller 1207 and avoid damage to the flatness of the concrete surface.

[0036] like Figures 12-16 As shown, the central slide table 3000 includes a central slide table frame 3001, a load-bearing roller 3002, a central slide table transverse motor 3003, a reversing reducer 3004, a transverse gear 3005, a slide table cylinder 3006, a cylinder mounting bracket 3007, a slide table lower platform connecting shaft seat 3008, a first slide table lower platform 3009, a second slide table lower platform 3010, a rotating platform 3011, a track slide table attitude detector 3012, a smoothing tool b 3013, a slide table 3014, a vibrator 3015, a vibrator guide pulley 3016, a rotating platform drive gear 3017, a rotating platform bottom bearing 3018, a rotating platform motor assembly 3019, and a slide table lower platform end cover 3020. Specifically, the central slide frame 3001 is the main load-bearing component of the entire central slide. The load-bearing rollers 3002 are bolted to the underside of the crossbeam of the central slide frame 3001, allowing for smooth movement on the track 1309 while bearing the weight of the central slide 3000. The central slide transverse motor 3003 is mounted on the longitudinal beam of the central slide frame 3001. The output shaft of the central slide transverse motor 3003 is connected to a reversing reducer 3004, and the output shaft of the reversing reducer 3004 is directly connected to a transverse gear 3005, which meshes with the track tooth groove 1309c on the track 1309. When the central slide 3000 moves along the track 1309, the central slide transverse motor 3003 is activated. The output torque of the central slide transverse motor 3003 is amplified by the reversing reducer 3004 and drives the transverse gear 3005 to move along the track 1309.

[0037] The slide cylinder 3006 is fixed to the top and middle of the central slide frame 3001 using a cylinder mounting bracket 3007. The two slide cylinders 3006 are arranged in a group, one in front of the other. The bottom of the slide cylinder is bolted to the slide lower platform connecting pivot 3008. The slide lower platform connecting pivot 3008 can increase the pitch range of the slide lower platform. The pitch angle of the slide lower platform can be controlled by controlling the extension length of the two sets of slide cylinders 3006. The lower platform of the slide table mainly consists of a first lower platform 3009 and a second lower platform 3010. The top of the first lower platform 3009 has a screw hole, and the lower platform connecting shaft seat 3008 is connected and fixed to the first lower platform 3009 by bolts passing through the screw hole. The cylindrical boss end face of the first lower platform 3009 is provided with a first thread and an end cap hole 3009a. The middle part of the second lower platform 3010 is provided with a second thread and an end cap hole 3010a. The first lower platform 3009 and the second lower platform 3010 are directly threaded together. The lower platform end cap 3020 is installed at the bottom of the second lower platform 3010 to fix the two platforms together.

[0038] The bottom bearing 3018 of the rotating platform is installed in the annular groove at the center of the top of the second lower slide platform 3010. The rotating platform drive gear 3017 passes through the cylindrical boss of the first lower slide platform 3009 and is interference-fitted onto the outside of the bottom bearing 3018. A protruding post is provided at the top of the rotating platform drive gear 3017 away from its center. A circular hole for inserting the protruding post is provided at the protruding end of the rotating platform 3011. The rotating platform 3011 and the rotating platform drive gear 3017 are stacked vertically, and the rotating platform drive gear 3017 drives the rotating platform 3011 to rotate. A threaded hole for mounting the rotating platform motor assembly 3019 is provided on the disc at the bottom of the second lower slide platform 3010. The output shaft of the rotating platform motor assembly 3019 is connected to a pinion gear, which meshes with the rotating platform drive gear 3017. Starting the motor controls the rotation of the rotating platform 3011. The track slide attitude detector 3012 is installed on the rotary platform 3011 and is responsible for monitoring the pitch and height data of the rotary platform 3011 and transmitting them to the control box.

[0039] The slide table 3014 is mounted on one extended end of the rotating platform 3011. The vibrator 3015 is fixed to the movable part of the slide table 3014. The vibrator guide pulley 3016 is mounted on the same end of the rotating platform 3011 and the slide table 3014. The actuating part of the vibrator 3015 is released through the vibrator guide pulley 3016 to prevent obstruction of movement or collision. The smoothing tool b3013 is bolted to the bottom of the other extended end of the rotating platform 3011.

[0040] like Figure 17 As shown, the tail slide rail 4100 is installed at the rear of the traveling unit 1000. This structure also adopts a splicing design and can be expanded according to the working environment. The tail slide 4000 includes the tail slide rail 4100 and the tail slide platform 4200. The tail slide platform 4200 slides laterally on the tail slide rail 4100, undertaking the work of watering maintenance and mulching.

[0041] like Figures 18-20As shown, the tail slide rail 4100 includes a steel bracket 4101, a rail mounting component 4102, a splicing rail 4103, a rail upper splicing component 4104, and a rail side splicing component 4105. The steel bracket 4101 is fixed to the corresponding holes in the welded frame 1101 with bolts, and it also has slots for the rail mounting component 4102 to be fixed with bolts. The cross-section of the splicing track 4103 is a U-shape with an inward bend. The inner side of the inward bend has a trapezoidal cross-section track. The two ends of its flat section have on-track splicing holes 4103a, and the two ends of its side section have on-track splicing holes 4103b. The two splicing tracks 4103 are a group, with the opening facing downward. They are installed under the slots of the flat section of the track mounting component 4102 and are connected and fixed by bolts passing through the on-track splicing holes 4103a. The track-side splicing component 4105 is divided into an inner part 4105a and an outer part 4105b. The inner part 4105a passes through the on-track splicing hole 4103b from the inner wall of the splicing track 4103. The outer part 4105b is aligned with the screw holes at the ends of the four protruding columns of the inner part 4105a from the outside and is locked with fastening screws to prevent the splicing track 4103 from lateral displacement. For the parts that do not require the use of track mounting parts 4102 to fix to the steel bracket 4101, the track splice 4104 is bolted to the top of the track splice hole 4103a. The track splice 4104 uses two reinforcing ribs to improve bending resistance and prevent the spliced ​​track 4103 from breaking at the weak connection.

[0042] The tail slide platform 4200 includes a tail slide main structure, a tail slide drive mechanism, a spray device, a plastic film laying device, and a fan assembly 4300. The fan assembly 4300 is mounted on the rear of the tail slide platform 4200 using a bracket. During the laying of the curing plastic film, it applies downward pressure to ensure that the curing plastic film can adhere relatively well to the concrete surface under certain disturbance conditions.

[0043] like Figure 21 and Figure 22 As shown, the main structure of the tail slide includes an irregularly shaped frame 4201, a water tank fixing component 4202, and a water tank 4203. The irregularly shaped frame 4201 has multiple holes, which form the basis for subsequent installation devices. The water tank fixing component insertion holes 4201d are located at the four corners of the flat area in the middle of the irregularly shaped frame 4201. The water tank fixing component 4202 has three protruding pillars that are inserted into the water tank fixing component insertion holes 4201d with an interference fit. The water tank 4203 is movably inserted between the four water tank fixing components 4202, which facilitates the addition of spray water or replacement of the water tank during actual operation.

[0044] like Figure 23 and Figure 24As shown, the tail slide drive mechanism includes a T-shaped support frame 4204, a tail slide pulley shaft 4205, a tail slide pulley 4206, a tail slide pulley end cover 4207, and a tail slide motor drive component 4208. The tail slide drive mechanism slides within the U-shaped opening of the splicing track 4103. Support is provided by the tail slide pulley 4206 directly engaging with the trapezoidal cross-section track of the splicing track 4103. The T-shaped support frame 4204 consists of a lower T-shaped support frame 4204a and an upper T-shaped support frame 4204b, fixed together with screws. The connecting hole 4204c between the support frame platforms is located at the bottom of the lower T-shaped support frame 4204a and is secured using coarse bolts and a special-shaped structural frame 4201. Bearings are installed between the lower T-shaped support frame 4204a and the upper T-shaped support frame 4204b. The tail slide pulley shaft 4205 passes through the bearings, and tail slide pulleys 4206 are installed at both ends, secured coaxially with the tail slide pulleys 4206 using keys. The hubs of the tail slide pulleys 4206 are covered with rubber to increase friction with the trapezoidal cross-section track and prevent accidental slippage.

[0045] The tail slide roller shaft 4205 has screw holes at both ends. After the tail slide roller 4206 is installed, the tail slide roller end cap 4207 is attached to both ends of the tail slide roller shaft 4205. Screws are screwed into the screw holes to position the tail slide roller 4206 at both ends of the slide roller shaft 4205. The tail slide motor drive 4208 is installed on one side of the lower T-shaped support frame 4204a. The output shaft of the motor of the tail slide motor drive 4208 is connected to a pulley, and the belt drives the tail slide roller 4206 to rotate. By controlling the speed and direction of rotation of the motor, the movement direction and speed of the tail slide platform 4200 on the splicing track 4103 can be controlled.

[0046] like Figure 25As shown, the spraying device includes a gear pump a4209, a gear pump b4210, a gear pump motor a4211, a gear pump motor b4212, and a spray head 4213. The gear pump a4209 is bolted into the gear pump mounting hole a4201a on the irregular structural frame 4201. A pipeline is led out from the water tank 4203 and connected to the input port of the gear pump a4209. The gear pump motor a4211 is fixed to one side of the irregular structural frame 4201. The output shaft of the gear pump motor a4211 is connected to a bevel gear to drive the gear pump motor a4211 to pump water. The water supply pipeline passes through the hole 4201b and is installed in front of the irregular structural frame 4201. Water is supplied by the spray head 4213 at the bottom side, which sprays water in the direction of the slide platform's movement. The gear pump b4210 is bolted into the gear pump mounting hole b4201c, and the gear pump motor b4212 is fixed to the other side of the irregular frame 4201. The gear pump b4210 is also driven by a bevel gear. A pipeline is led from the water tank 4203 to the input port of the gear pump b4210. The spray head 4213 in this section sprays water in the completed smoothing direction. After the smoothing process is completed, the equipment starts the tail slide platform motor drive 4208, gear pump a4209, and gear pump b4210 according to remote control commands. The gear pumps begin pumping water from the water tank 4203, and the spray heads 42013 installed in both directions begin working, wetting the smoothed concrete surface.

[0047] like Figure 26 As shown, the plastic film laying device includes a plastic film loading shaft 4214, a plastic film loading shaft drive motor 4215, a plastic film loading shaft bearing seat 4216, a plastic film cutting ring 4217, a plastic film cutting ring rotating gear 4218, a cutting ring drive motor 4219, a traction rod and a cutting blade 4220, and a curing plastic film 4221. The plastic film loading shaft 4214 passes through holes on both sides of the bottom of the irregular structure frame 4201, and plastic film loading shaft bearing seats 4216 are installed at both ends to reduce the rotational friction between the plastic film loading shaft 4214 and the irregular structure frame 4201. The curing plastic film 4221 is directly fitted onto the outer ring of the plastic film loading shaft 4214. The plastic film loading shaft drive motor 4215 is also installed on one side of the bottom of the irregular structure frame 4201. A pulley is installed at one end of the plastic film loading shaft 4214. The output shaft of the plastic film loading shaft drive motor 4215 is connected to the pulley to drive the plastic film loading shaft 4214 to rotate and release the curing plastic film 4221.

[0048] A plastic film cutting ring 4217 is fitted onto both ends of a plastic film loading shaft 4214, allowing for smooth rotation between them. The outer circumference of the plastic film cutting ring 4217 has a groove, and the inner circumference of the plastic film cutting ring rotating gear 4218 has a complementary boss, with the two nested together. A cutting ring drive motor 4219 is mounted on the other side of the bottom of the irregularly shaped frame 4201. The output shaft of the cutting ring drive motor 4219 is fitted with a gear that meshes with the plastic film cutting ring rotating gear 4218. The rotation of the cutting ring drive motor 4219 controls the rotation of the traction rod and cutting blade 4220 mounted on the plastic film cutting ring 4217.

[0049] As described above, the present invention combines several basic units, including a walking unit 1000, a tail smoothing part 2000, a central slide 3000, and a tail slide 4000, based on the structure of two types of interlocking tracks, a ring vibratory smoothing operation platform, an automatic laying and cutting device for curing plastic film, and an automatic spray curing device.

[0050] This invention enables the equipment to adapt to different working areas by constructing modular working units. For narrow paving areas, only two working units can be used in combination, while for paving tasks on large open terrain, multiple working units are assembled horizontally to form a whole. This design eliminates the need to break down large-area paving into multiple small areas for step-by-step operations, improving the equipment's working efficiency and solving the problem of asynchronous concrete setting time caused by the small single working area when using small equipment in large-area paving scenarios.

[0051] The central slide 3000 constructed by this invention realizes the function of smoothing concrete under different slope conditions. When facing a sloping working surface, the central slide 3000 of this invention uses a slide cylinder to adjust the angle between the working tool and the working surface. Under the control of the track seat 1300, the smoothing surface of the smoothing tool can fit well with the concrete surface, avoiding the equipment from intruding into the concrete and damaging the surface smoothness under sloping conditions.

[0052] This invention utilizes a multi-functional tail slide 4000 to achieve rapid integration of concrete smoothing and coating processes. Traditional methods inevitably involve a long gap between smoothing and coating, during which foreign matter may enter the smoothed concrete, damaging its appearance. Furthermore, the long interval between the two processes leads to moisture evaporation from the concrete surface, reducing the effectiveness of concrete curing. The tail slide 4000 moves with the entire equipment, initiating the spraying and coating processes immediately after smoothing is completed. The concrete surface is thoroughly moistened, and the coating device can be operated quickly to apply the coating, thereby improving the quality of concrete curing.

[0053] The following describes the specific operating procedures for this assembled concrete vibration, smoothing, curing, and coating equipment: 1. Identify the area that needs concrete paving, conduct a preliminary assessment of the area, and confirm that the area is suitable for the use of this equipment.

[0054] 2. To ensure the smooth progress of subsequent paving operations, select a starting point and assemble the equipment. After assembly, power on the control box and start it up to test the control system and testing instruments. Once all testing items are completed, the equipment will be put into standby mode.

[0055] 3. Use the controller to set the angle of the central slide 3000. Specifically, set the distance between the track slide attitude detector and the trail smoothing attitude detector and the concrete surface, i.e., how close the central slide smoother and trail smoother are to the concrete surface, and the pitch angle of the two smoothers relative to the horizontal plane; set the position of the slide, and confirm whether the vibrator 3015 penetrates the concrete surface sufficiently; set the speed of the left and right lateral movement of the central slide 3000, the cycle of the rotating platform's circular operation, and the cycle of the vibrator penetrating the concrete; check whether the curing and film-covering slides slide freely, and initialize the slide position and the reference speed of slide movement; fill the water tank with water, turn on the gear pump and test the operation of the spray components; load the plastic film roll for film covering; set the reference speed for the forward movement of the traveling unit. After completing the above settings, start the test, make minor adjustments based on the test results, and prepare to begin formal operation.

[0056] 4. The entire equipment starts operating from the entry point. The construction personnel start the walking drive motor, and the equipment begins to move forward. The central slide 3000 then begins to work. The vibrator 3015 of the central slide 3000 is inserted into the road surface according to the set data. During this process, the control box automatically judges the insertion depth and insertion time of the vibrator. After the vibration of a section is completed, the control box 1108 issues a command to drive the slide and rotating platform to perform the operation according to the set movement path, repeating the rotation and insertion vibration process. After the vibration is completed, the trowel enters and, under the monitoring of the computer, continuously contacts the concrete surface according to the set trajectory to perform the troweling operation.

[0057] 5. After the vibration and smoothing work in this area is completed, the tail slide 4000 first moves to one end of the track near the edge of the concrete surface. The construction personnel start the motor to release the curing plastic film 4221 at the bottom of the platform. After the curing plastic film 4221 accumulates at one end outside the concrete edge, the slide movement motor, spray device, and fan group 4300 are activated. When the curing plastic film 4221 is tensioned, the cutting ring drive motor 4219 is activated, causing the traction rod to approach the plastic film from below, which plays a supporting role and limits the angle of contact between the plastic film and the concrete surface and the length of the suspension. The slide moves forward along the track to fully wet the concrete surface, and the curing plastic film 4221 then covers the exposed concrete surface. The entire slide operates automatically at a set uniform speed.

[0058] 6. When the entire tail slide 4000 moves to the other end of the track, the cutting ring drive motor 4219 starts again, driving the blade to cut the plastic film at high speed. After cutting, the slide drive motor reverses, driving the slide back to the starting position, and then repeats steps 4 and 5. The equipment selects the movement path under remote control or program design, completing the entire process of vibration, smoothing, curing, and film covering layer by layer until it reaches the target point of concrete laying. The equipment stops moving after the detection position reaches the endpoint, waiting for acceptance confirmation.

[0059] 7. Conduct an acceptance inspection of the surface that has been covered with film. Manually repair any corners and edges that are difficult for the equipment to cover. After confirming that there are no defects in the work area, disassemble and pack the equipment, load it onto a truck, and transport it to the warehouse for storage.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of the present invention.
