[0002] ‌Concrete pouring thickness control device‌ is a tool or device used to ensure thickness control during concrete pouring. The design and function of these devices vary, but the common goal is to ensure that the thickness of concrete pouring meets the design requirements, thereby improving construction quality.

[0003] Existing thickness control devices for concrete pouring mostly use steel angle brackets or plastic brackets to support the steel structure in the concrete, and mark the thickness of the concrete pouring by controlling the height of the steel structure. However, in the actual pouring process, since the existing thickness control devices are mostly multi-point support settings, not only are they difficult to disassemble, but concrete pouring is mostly point pouring, causing the concrete to flow around. The flowing concrete is also prone to cause the thickness control equipment to tilt, thereby affecting the detection of the concrete pouring thickness. For this reason, we propose a concrete pouring thickness control device. Summary of the invention

[0015] The working principle and beneficial effects of the present invention are: 1. The present invention installs a concrete trowel frame on a device with lifting and moving functions in the prior art, drives the concrete trowel frame to move toward the surface of the poured concrete through the prior equipment, makes the concrete trowel plate contact the concrete surface, and then starts the power motor, the output end of the power motor drives the power reciprocating screw to rotate, the rotation of the power reciprocating screw drives the power ball nut to perform linear reciprocating motion, the linear reciprocating motion of the power ball nut group drives the concrete trowel plate to perform linear reciprocating motion, through the linear reciprocating motion of the concrete trowel plate, not only the poured and accumulated concrete can be smoothed, but also the concrete can be accelerated to flow around, and in the process of smoothing, due to the reciprocating motion of the concrete trowel plate, vibration is generated to compact the concrete; 2. In the present invention, during the linear reciprocating motion of the concrete trowel plate, the concrete trowel plate will drive the gas delivery slide bar to move, and the movement of the gas delivery slide bar will drive the gas delivery slider to move. When the gas delivery slider moves in the direction away from the three-way gas delivery pipe, the gas in the negative pressure gas box will enter the gas cylinder through the suction pipe and the suction one-way valve. When the gas delivery slider moves in the direction close to the three-way gas delivery pipe, the gas in the gas cylinder will enter the positive pressure gas box through the exhaust pipe and the exhaust one-way valve. When the air pressure in the negative pressure gas box drops to a set value, the external gas will enter the negative pressure gas box through the intake air pressure regulating valve. When the air pressure in the positive pressure gas box rises to a set value, the gas in the positive pressure gas box will be discharged to the air through the exhaust air pressure regulating valve. 3. In the process of the concrete trowel plate smoothing the concrete, the longitudinal adjustment air inlet valve is opened to allow the gas in the positive pressure air box to enter the longitudinal adjustment cylinder through the longitudinal adjustment air inlet pipe, the longitudinal adjustment main pipe, the horizontal adjustment telescopic hose and the longitudinal adjustment air pipe, so that the air pressure in the longitudinal adjustment cylinder increases. As the pressure in the longitudinal adjustment cylinder increases, the depth control rod moves in a direction away from the longitudinal adjustment cylinder, so that after the depth control rod is extended, the vertical distance between the bottom of the depth control rod and the bottom of the concrete trowel plate is the thickness of the concrete pouring. After the depth control rod is inserted into the ground below the concrete, the flatness of the concrete after pouring can be ensured by smoothing the concrete trowel plate; 4. The present invention does not need to accurately position the steel structure in advance when controlling the thickness of concrete after pouring. The position can be directly positioned by the depth control rod. As the concrete leveling frame moves, the gathered concrete can be driven to move around by the movement of the depth control rod. Moreover, as the depth control rod moves the concrete, the longitudinal adjustment air inlet valve and the longitudinal adjustment exhaust valve can be started alternately. When the longitudinal adjustment exhaust valve is started, the gas in the longitudinal adjustment cylinder will enter the negative pressure air box through the longitudinal adjustment air pipe, the horizontal adjustment telescopic hose, the longitudinal adjustment main pipe, and the longitudinal adjustment exhaust pipe, so that the depth control rod can perform a linear reciprocating motion to improve the density, strength and durability of the concrete.

[0016] 5. In the present invention, when the depth of concrete is fixed and leveled, when the movement of the depth control rod is hindered, the horizontal adjustment air inlet valve and the horizontal adjustment exhaust valve can be started alternately. When the horizontal adjustment air inlet valve is started and the horizontal adjustment exhaust valve is closed, the gas in the positive pressure air box will enter the horizontal adjustment cylinder through the horizontal adjustment air inlet pipe, the horizontal adjustment main pipe and the horizontal adjustment air pipe, so that the horizontal adjustment bent rod drives the horizontal adjustment telescopic pipe to move toward the side away from the concrete leveling frame. Conversely, when the horizontal adjustment exhaust valve is opened and the horizontal adjustment air inlet valve is closed, the gas in the horizontal adjustment cylinder will enter the negative pressure air box through the horizontal adjustment air pipe, the horizontal adjustment main pipe and the horizontal adjustment exhaust pipe, so that the horizontal adjustment bent rod drives the horizontal adjustment telescopic pipe to move toward the side close to the concrete leveling frame, thereby adjusting the position of the depth control rod and effectively ensuring that the depth control rod can pass over each steel structure during the normal leveling of the concrete leveling plate.

[0032] The pneumatic adjustment unit includes a horizontal adjustment main pipe 26, a horizontal adjustment air intake pipe 27, a horizontal adjustment exhaust pipe 29, a vertical adjustment main pipe 31, a vertical adjustment air intake pipe 32 and a vertical adjustment exhaust pipe 34.

Between the negative pressure air box 24, a horizontal adjustment exhaust valve 30 is installed on the horizontal adjustment exhaust pipe 29, the vertical adjustment main pipe 31 is set on one side of the concrete leveling frame 1, the vertical adjustment main pipe 31 is connected with the horizontal adjustment telescopic hose, the vertical adjustment air inlet pipe 32 is connected between the vertical adjustment main pipe 31 and the positive pressure air box 22, the vertical adjustment air inlet pipe 32 is installed with a vertical adjustment air inlet valve 33, the vertical adjustment exhaust pipe 34 is connected between the vertical adjustment main pipe 31 and the negative pressure air box 24, and the vertical adjustment exhaust valve 35 is installed on the vertical adjustment exhaust pipe 34.

[0033] Specifically, during the linear reciprocating motion of the concrete trowel plate 2, the concrete trowel plate 2 will drive the gas supply slide rod 16 to move, and the movement of the gas supply slide rod 16 will drive the gas supply slider 15 to move. When the gas supply slider 15 moves in a direction away from the three-way gas supply pipe 17, the gas in the negative pressure air box 24 will enter the gas cylinder 14 through the suction pipe 18 and the suction check valve 19. When the gas supply slider 15 moves in a direction close to the three-way gas supply pipe 17, the gas in the gas cylinder 14 will enter the positive pressure air box 22 through the exhaust pipe 20 and the exhaust check valve 21. When the air pressure in the negative pressure air box 24 drops to a set value, the external gas will enter the negative pressure air box 24 through the intake pressure regulating valve 25. When the air pressure in the positive pressure air box 22 rises to a set value, the gas in the positive pressure air box 22 will be discharged to the air through the exhaust pressure regulating valve 23.

[0034] During the process of the concrete trowel plate 2 smoothing the concrete, the longitudinal adjustment air inlet valve 33 is opened to allow the gas in the positive pressure air box 22 to enter the longitudinal adjustment cylinder 10 through the longitudinal adjustment air inlet pipe 32, the longitudinal adjustment main pipe 31, the transverse adjustment telescopic hose and the longitudinal adjustment air pipe 12, so that the air pressure in the longitudinal adjustment cylinder 10 increases. As the pressure in the longitudinal adjustment cylinder 10 increases, the depth control rod 11 moves in the direction away from the longitudinal adjustment cylinder 10, so that after the depth control rod 11 is extended, the vertical distance between the bottom of the depth control rod 11 and the bottom of the concrete trowel plate 2 is the thickness of the concrete pouring. After the depth control rod 11 is inserted into the ground below the concrete, the flatness of the concrete after pouring can be ensured by smoothing the concrete trowel plate 2.

[0035] It should be noted that when controlling the thickness of concrete after pouring, there is no need to accurately position the steel structure in advance. The position can be directly positioned through the depth control rod 11, and as the concrete leveling frame 1 moves, the gathered concrete can be driven to move around under the manipulation of the depth control rod 11. In addition, as the depth control rod 11 manipulates the concrete, the longitudinal adjustment air intake valve 33 and the longitudinal adjustment exhaust valve 35 can be alternately started. When the longitudinal adjustment exhaust valve 35 is started, the gas in the longitudinal adjustment cylinder 10 will enter the negative pressure air box 24 through the longitudinal adjustment air pipe 12, the horizontal adjustment telescopic hose, the longitudinal adjustment main pipe 31, and the longitudinal adjustment exhaust pipe 34, so that the depth control rod 11 performs a linear reciprocating motion to improve the density, strength and durability of the concrete.

[0036] When the depth of concrete is fixed and leveled, if the movement of the depth control rod 11 is hindered, the horizontal adjustment air inlet valve 28 and the horizontal adjustment exhaust valve 30 can be started alternately. When the horizontal adjustment air inlet valve 28 is started and the horizontal adjustment exhaust valve 30 is closed, the gas in the positive pressure air box 22 will enter the horizontal adjustment tube 6 through the horizontal adjustment air inlet pipe 27, the horizontal adjustment main pipe 26 and the horizontal adjustment air pipe 9, so that the horizontal adjustment bent rod 8 drives the horizontal adjustment telescopic pipe 13 to move toward the side away from the concrete leveling frame 1. On the contrary, when the horizontal adjustment exhaust valve 30 is opened and the horizontal adjustment air inlet valve 28 is closed, the gas in the horizontal adjustment tube 6 will enter the negative pressure air box 24 through the horizontal adjustment air pipe 9, the horizontal adjustment main pipe 26 and the horizontal adjustment exhaust pipe 29, so that the horizontal adjustment bent rod 8 drives the horizontal adjustment telescopic pipe 13 to move toward the side close to the concrete leveling frame 1, thereby adjusting the position of the depth control rod 11 and effectively ensuring that the depth control rod 11 can pass over each steel structure during the normal leveling of the concrete trowel plate 2.
