[0020] Refer to Figure 1, the utility model relates to a self-leveling floor construction device that is convenient to control the thickness. The main structure includes a moving frame 1, and the moving frame 1 plays a supporting role. The bottom of the moving frame 1 is provided with moving wheels 2. Preferably, a handrail can be arranged at one end of the moving frame 1. Through the handrail, the moving frame 1 can be conveniently pushed to move to the construction position under the action of the moving wheels 2. A material box 3 is arranged on the moving frame 1, and the material box 3 is used to store the liquid material required for construction. A communicating discharge channel 4 is arranged at the bottom of the material box 3. Specifically, a discharge hole can be arranged on the moving frame 1, and the discharge channel 4 is communicated with the discharge hole, so that the liquid material is discharged from the discharge hole along the discharge channel 4. An electromagnetic valve 5 for controlling its opening and closing is arranged in the discharge channel 4. The electromagnetic valve 5 is a normally open structure. Specifically, a normally open solenoid valve with a model of AC220VDC24V sold by Yuyao Jingrong Valve Factory can be selected. It is in an open state during use, so that the liquid material in the material box 3 can continuously pass through the discharge channel 4 for discharging. A floating box 6 is slidably connected to the bottom of the moving frame 1 in the vertical direction. The floating box 6 is a hollow box structure. Under the action of gravity, it is at a lower position. After the liquid material automatically flows and spreads out, its thickness gradually increases. After contacting the bottom of the floating box 6, it drives the floating box 6 to slide upward. A contact switch 7 electrically connected to the electromagnetic valve 5 is arranged on the moving frame 1. The contact switch 7 can be a contact switch structure with a model of GT2-71MCN sold by Keyence Corporation. It is electrically connected to the electromagnetic valve 5. A contact rod 8 is welded or bolted to the floating box 6. When the floating box 6 slides upward, the contact rod 8 contacts the contact switch 7. Preferably, the contact rod 8 is arranged in the middle of the floating box 6. After the floating box 6 is pushed upward by the liquid material and slides, the contact rod 8 gradually approaches the contact switch 7. When the two contact, the electromagnetic valve 5 is controlled to close, so as to close the discharge channel 4, so that the liquid material cannot continue to flow out of the discharge channel 4, thereby realizing the automatic control of the material thickness. The setting of the floating box 6 makes its contact area with the liquid material larger, and the control of the construction thickness of the liquid material is more accurate and uniform, without the need for manual measurement and control, greatly improving the accuracy and uniformity of the construction thickness control in the self-leveling floor construction technology.

[0021] Preferably, an inner cavity 9 is arranged at the bottom of the moving frame 1, and the floating box 6 is slidably connected in the inner cavity 9. The floating box 6 is in sliding contact with the inner wall of the inner cavity 9, so that the overall floating box 6 is more stable when sliding up and down, so that the construction thickness of the liquid material at each position can reach the specified height before driving the overall floating box 6 to slide upward, making the control of the construction thickness at each position more accurate and uniform. A fixing groove 10 is arranged in the inner cavity 9, and the contact switch 7 is arranged in the fixing groove 10. The fixing groove 10 can protect the contact switch 7 and avoid possible accidental contact caused by other external components, further improving the accuracy of the construction thickness control.

[0022] Preferably, a slider 11 is slidably connected to the fixing groove 10 in the vertical direction. The contact switch 7 is welded or bolted to the slider 11. A power rod 12 for driving the slider 11 to slide up and down is provided in the fixing groove 10. Such a structure can use the power rod 12 to drive the slider 11 to slide up and down, so that the position of the contact switch 7 on the slider 11 can be adjusted adaptively according to the actual use requirements, thereby meeting the requirements of different construction thicknesses and improving the adaptability of the device in actual use.

[0023] Preferably, referring to Figure 3 , the power rod 12 is rotatably connected to the fixing groove 10 through a bearing. The power rod 12 passes through the slider 11 and is threadedly connected thereto. Such a structure can drive the slider 11 to slide in the fixing groove 10 by rotating the power rod 12 under the action of the threaded connection, making the sliding control of the position of the slider 11 more convenient and accurate. Preferably, according to the requirements of the actual installation position, a knob can be rotatably provided on the moving frame 1. A synchronous pulley is provided at the bottom of the knob, and a synchronous pulley is also provided on the power rod 12. The two synchronous pulleys are connected by a synchronous belt. Such a structure can arrange the knob outside the moving frame 1, while the power rod 12 and other structures can be arranged inside the moving frame 1, so as to hide the structures related to the power rod 12 in a position not easily touched by mistake, and conveniently control the rotation of the power rod 12 by using the knob, further improving the convenience of actual use.

[0024] Preferably, referring to Figure 2 , an adjusting rod 13 is rotatably connected to the inner cavity 9 through a bearing. A fixing sleeve 14 is slidably connected to the floating box 6. A limiting plate for cooperating with the floating box 6 is provided at the bottom of the fixing sleeve 14. The adjusting rod 13 is threadedly connected to the inside of the fixing sleeve 14. Such a structure can drive the fixing sleeve 14 to move up and down by rotating the adjusting rod 13 under the action of the threaded connection, so that the limiting plate at the bottom of the fixing sleeve 14 moves up and down, controlling the maximum distance that the floating box 6 moves downward along the fixing sleeve 14 under the action of gravity, and thus the lowest position of the floating box 6 can be adjusted according to the actual use requirements, further improving the adaptability of the device in actual use.

[0025] Preferably, a plurality of stirring shafts 15 are rotatably connected to the bottom inside the material box 3 through bearings. One of the stirring shafts 15 is driven to rotate by a motor. The plurality of stirring shafts 15 are connected by a synchronous belt. A plurality of stirring rods 16 are welded or bolted to the stirring shafts 15. The stirring shafts 15 are used to drive the plurality of stirring rods 16 to rotate, realizing the stirring of the liquid material at the bottom of the material box 3, thereby preventing the particulate matter in the material from blocking the discharge channel 4 and ensuring the smooth discharge of the liquid material.

[0026] Working principle: In the structure of the present utility model, a material box 3 for storing liquid materials is arranged on the moving frame 1. A discharge channel 4 is provided at the bottom of the material box 3, and an electromagnetic valve 5 for controlling its opening and closing is arranged in the discharge channel 4. A contact switch 7 electrically connected to the electromagnetic valve 5 is arranged on the moving frame 1. A touch rod 8 that slides up and down is provided at the bottom of the moving frame 1. When the liquid material flows and thickens, the touch rod 8 is driven to slide upward until the electromagnetic valve 5 closes when the touch rod 8 contacts the contact switch 7, so that the liquid material cannot continue to flow out of the discharge channel 4, thereby realizing the automatic control of the construction thickness. There is no need for manual monitoring and intervention, which greatly improves the accuracy and convenience of the construction thickness control and ensures the accuracy and uniformity of the construction thickness at each position; a floating box 6 is slidably arranged vertically at the bottom of the moving frame 1, and the touch rod 8 is arranged in the floating box 6. Such a structure makes the floating box 6 located at a low position below the moving frame 1 under the action of gravity. During the construction of the flowing liquid material, the floating box 6 contacts a large range of liquid materials. Only when the thickness of the liquid material reaches the specified requirements at most construction positions can the gravity of the floating box 6 be overcome to drive the touch rod 8 to slide upward and contact the contact switch 7. Furthermore, the control of the construction thickness is no longer limited to a single point of the touch rod 8, further improving the accuracy of the construction thickness control.
