[0021] A construction method for large-area concrete floor pouring equipment, the specific steps are as follows:

[0022] S1. Concrete preparation and delivery: The concrete raw materials are added to the mixing bin through the feeding port, and the mixing device is started for mixing. The mixed concrete enters the delivery pump through the connecting pipe, and is pumped by the delivery pump to the storage tank of the pouring device through the delivery pipeline. The delivery pipeline is threadedly connected to the threaded connection port of the mixing device through the threaded pipe mouth. The silicone rubber sealing ring at the interface prevents leakage of slurry, and the Teflon coating on the inner wall of the pipe reduces material adhesion.

[0023] S2. Casting height adjustment: According to the thickness of the floor casting or the undulation of the ground, the driving structure is activated through the controller: the rotating motor drives the rotating screw to rotate, so that the rectangular sliding block mounted on the screw moves up and down along the thread direction, and the rectangular contact plate is pushed through the connecting rod, driving the telescopic table legs to extend and retract within the connecting legs, thereby achieving precise adjustment of the casting device height.

[0024] S3. Concrete pouring control: Push the equipment to move the rotating wheels. The anti-slip pad on the handrail surface is fixed to the slot with a circular silicone edging strip to prevent your hands from slipping. Open the valve on the side of the rectangular plate to control the concrete in the storage box to flow out evenly from the pouring port. Adjust the valve opening and closing according to the pouring area.

[0025] S4. Equipment stability monitoring: The inclination sensor monitors the equipment's tilt angle in real time. When the tilt angle exceeds 5°, the controller triggers a buzzer alarm. The operator adjusts the equipment's position using the rubber cushions at the bottom of the retractable table legs. At the same time, the cross-shaped reinforcement ribs at the bottom of the rectangular mounting plate enhance structural stability.

[0026] The present invention has the following beneficial effects:

[0027] 1. In the present invention, the equipment is connected to the pouring device through a conveying pipe between the stirring device and the pouring device. The silicone rubber sealing ring embedded in the interface can tightly fill the connection gap, effectively preventing the concrete slurry from leaking during the conveying process. The Teflon coating on the inner wall of the conveying pipe significantly reduces the adhesion of the concrete slurry to the inner wall of the pipe due to its low surface energy characteristics. In the pouring device, the inclination sensor set between the connecting table leg and the telescopic table leg can monitor the inclination angle of the device in real time. When the ground is undulating or the pouring thickness changes, the motor in the drive structure drives the screw to rotate, pushing the telescopic table leg to the connecting table leg. The inward telescopic structure enables dynamic adjustment of the height of the pouring device. The rotating wheels installed at the bottom of the telescopic table legs are provided with anti-skid grooves, which can not only flexibly turn and move on the construction site, but also provide sufficient friction on wet or rough ground to prevent the equipment from slipping and shifting. The edge of the anti-skid pad bonded to the surface of the handrail is fixed with a ring-shaped silicone edging strip and a card slot, which not only avoids the problem of the edge of the anti-skid pad curling and falling off after long-term use, but also ensures that the operator's hands always maintain a stable grip when pushing the equipment by enhancing the bonding strength between the anti-skid pad and the handrail, effectively improving the operational safety and convenience during the construction process.

[0028] 2. In the present invention, the equipment connecting plate, support column plate and reinforcement plate in the mixing device enhance the overall stability. The delivery pump is connected to the mixing bin through a connecting pipe, and the automatic control of concrete preparation and delivery is realized in conjunction with the operation panel. The storage box of the pouring device is connected to the delivery pump through a detachable delivery pipe, which is convenient for equipment disassembly and maintenance. The buzzer alarm function linked to the controller and the inclination sensor can monitor the stability of the equipment to avoid uneven pouring due to tilting. The design of the rotating motor in the driving structure drives the rectangular sliding block by rotating the screw to realize the height adjustment of the telescopic table legs. The cross-shaped reinforcement rib plate at the bottom of the rectangular mounting plate and the rubber buffer pad at the bottom of the telescopic table leg further enhance the equipment's load-bearing capacity and ground adaptability, and reduce the impact of vibration on pouring accuracy. In addition, the detachable design of the threaded connection port and the threaded pipe port, as well as the card slot edging structure of the anti-slip pad, all improve the durability and maintenance convenience of the equipment.

[0041] A construction method for large-area concrete floor pouring equipment, the specific steps are as follows:

[0042] S1. Concrete preparation and delivery: Concrete raw materials are added to the mixing chamber 8 through the feeding port 7, and the mixing device is started to mix. The mixed concrete enters the delivery pump 10 through the connecting pipe 9. The delivery pump 10 is pumped to the storage tank 13 of the pouring device through the delivery pipe 12. The delivery pipe 12 is threadedly connected to the threaded connection port 23 of the mixing device through the threaded pipe mouth 26. The silicone rubber sealing ring at the interface prevents leakage of slurry, and the Teflon coating on the inner wall of the pipe reduces material adhesion.

[0043] S2. Adjusting the pouring height: Based on the pouring thickness of the floor or the undulations of the ground, the driving mechanism is activated through the controller 17: the rotating motor 31 drives the rotating screw 33 to rotate, causing the rectangular sliding block 34 sleeved on the screw to move up and down along the thread direction, and the rectangular contact plate 36 is pushed by the connecting rod 35, driving the telescopic table leg 16 to extend and retract within the connecting table leg 15, thereby achieving precise adjustment of the height of the pouring device.

[0044] S3. Concrete pouring control: Push the equipment to move the rotating wheel 19. The anti-slip pad 21 on the surface of the handrail 27 is fixed to the slot with a circular silicone edging strip to prevent your hands from slipping. Open the valve 29 on the side of the rectangular plate 30 to control the uniform flow of concrete in the storage tank 13 from the pouring port 28. Adjust the opening and closing of the valve 29 according to the pouring area.

[0045] S4. Equipment stability monitoring: The inclination sensor monitors the equipment's tilt angle in real time. When the tilt angle exceeds 5°, the controller 17 triggers a buzzer alarm. The operator adjusts the equipment's position by retracting the rubber cushions at the bottom of the table legs 16. At the same time, the cross-shaped reinforcement ribs at the bottom of the rectangular mounting plate 14 enhance structural stability.

[0046] In S1, the concrete raw materials are fed into the mixing bin 8 through the feeding port 7, and after mixing, they are pumped into the storage box 13 through the connecting pipe 9, the delivery pump 10, and the delivery pipe 12. The silicone rubber sealing ring and the Teflon coating ensure that the delivery is leak-free and less sticking; in S2, the controller 17 starts the driving structure, and the rotating motor 31 drives the rotating screw 33 to adjust the height of the telescopic table legs 16 to adapt to the undulations of the ground; in S3, when pushing the equipment, the rotating wheels 19 cooperate with the anti-slip pad 21 to move, and the valve 29 controls the flow rate of the pouring port 28; in S4, the inclination sensor alarms when it exceeds 5°, and the reinforcement plate and rubber buffer pad are used to ensure the stability of the equipment. This method realizes the automatic control of the entire process of concrete preparation, delivery, and pouring through the coordinated work of various components of the equipment, improves the efficiency and quality of large-area floor pouring, and reduces labor intensity and construction costs.

[0047] Working principle: When the equipment is started, the concrete raw materials are put into the mixing bin 8 below the rectangular flat plate 6 through the feeding port 7 at the top of the mixing device. After the mixing device is started, the raw materials are mixed and stirred. The mixed concrete flows into the delivery pump 10 on the mounting plate 3 through the connecting pipe 9, and is pumped to the storage box 13 of the pouring device by the delivery pump through the delivery pipe 12. The end of the delivery pipe close to the mixing device is threadedly connected to the threaded connection port 23 of the mixing device through the threaded pipe mouth 26. The silicone rubber sealing ring embedded in the interface can effectively prevent leakage of concrete slurry. The Teflon coating on the inner wall of the pipe can reduce material adhesion, reduce transportation resistance, and ensure that the concrete is smoothly delivered to the storage box 13 for temporary storage.

[0048] When the pouring device is in operation, the driving structure can be started by the controller 17 to accurately adjust the pouring height: the rotating motor 31 is installed inside the connecting table leg 15, and its output end extends into the telescopic table leg 16 and is connected to the rotating screw 33. When the motor drives the screw to rotate, the rectangular sliding block 34 sleeved on the outer periphery of the screw moves up and down along the thread direction, and pushes the rectangular contact plate 36 through the connecting rod 35, thereby driving the telescopic table leg 16 to retract in the connecting table leg 15, realizing dynamic adjustment of the height of the pouring device to adapt to different pouring thicknesses or ground undulations; when the equipment moves, the rotating wheel 19 with anti-slip grooves at the bottom of the telescopic table leg 16 can flexibly turn, and the anti-slip surface of the handrail 27 The pad 21 is fixed to the card slot by an annular silicone edging strip to prevent the operator's hands from slipping. The valve 29 on the side of the rectangular plate 30 is opened, and the concrete in the storage box 13 flows out evenly from the pouring port 28. The pouring flow rate is controlled by adjusting the opening and closing degree of the valve. At the same time, the inclination sensor connected between the table leg 15 and the telescopic table leg 16 monitors the tilt angle of the equipment in real time. When the tilt exceeds 5°, the controller 17 triggers the buzzer alarm. The operator can adjust the position of the equipment through the rubber buffer pad at the bottom of the telescopic table leg, and cooperate with the cross-shaped reinforcement rib at the bottom of the rectangular mounting plate 14 to ensure that the equipment maintains structural stability during the pouring process to avoid uneven pouring due to tilt.
