Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, and particularly relates to a concrete surface leveling device. Background Art

[0002] Ordinary concrete refers to an artificial stone made by mixing cement as the main cementitious material, with water, sand, gravel, and chemical admixtures and mineral admixtures when necessary, in appropriate proportions, and then evenly mixing, compacting, forming, and curing to harden.

[0003] Concrete is often used in infrastructure construction. After laying, the surface of the concrete needs to be pressed and leveled before it dries and forms. Currently, surface leveling is usually required after concrete laying is completed. Small leveling devices are generally used for more detailed leveling. Manual control of the small leveling device is required, and the operator's control operation time is long. The height of the general small leveling device cannot be adjusted, and it cannot better adapt to the height and operating posture of different operators, so that the leveling equipment cannot be better operated, and the leveling efficiency is low.

[0004] Based on this, the applicant considered designing a concrete surface leveling device. Utility Model Content

[0019] The present invention will be described in further detail below with reference to the accompanying drawings.

[0020] When implementing: Figure 1-3 As shown, a concrete surface leveling device includes a cylinder 100, a leveling mechanism and an adjustment mechanism. A downward-opening stabilizing chamber 110 is provided in the cylinder 100. The leveling mechanism is installed in the stabilizing chamber 110 and extends below the bottom of the cylinder 100 for leveling the concrete. The adjustment mechanism is installed at the top of the cylinder 100 for adjusting the operating height of the cylinder 100.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] By providing the cylinder 100, the leveling mechanism and the adjustment mechanism, the leveling mechanism can level the concrete surface that needs to be leveled. At the same time, the leveling mechanism can adjust the leveling position under the drive of the cylinder 100, and the adjustment mechanism can adjust the operating height of the cylinder 100 to adapt to the operator's operation of processing the concrete surface in different operating positions or different heights, with better adaptability and higher leveling efficiency.

[0023] The above-mentioned concrete surface leveling device has the advantages of simple structure and easy implementation. It is suitable for installation and use in the existing concrete leveling process, and has low cost of use, which can improve benefits.

[0024] In this embodiment, Figure 1-3 As shown, the leveling mechanism includes a motor 210, a transmission rod 220 and a leveling plate 230. The motor 210 is installed in the cylinder 100 and is located at the top of the stabilizing cavity. The leveling plate 230 is arranged below the bottom of the cylinder 100. One end of the transmission rod 220 is coaxially connected to the rotating shaft of the motor 210, and the other end passes through the stabilizing cavity 110 and is coaxially connected to the center of the leveling plate 230.

[0025] In this way, by setting the motor 210, transmission rod 220 and screed plate 230, the motor 210 drives the screed plate 230 to rotate through the transmission rod 220 to level the concrete surface. The single leveling area is small, and a smaller area of ​​concrete surface can be leveled, which has higher adaptability.

[0026] In this embodiment, Figure 1-3 As shown, the screed plate 230 is circular, and a plurality of soil discharge grooves 231 are provided on the outer edge of the screed plate 230 .

[0027] In this way, by providing the soil discharge trough 231 , the screed plate 230 can discharge excess concrete through the soil discharge trough 231 when performing the leveling work, thereby achieving a better leveling effect.

[0028] In this embodiment, Figure 1-3 As shown, the soil discharge trough 231 is in a fan shape that gradually expands from the inside to the outside, and multiple soil discharge troughs 231 are opened on the screed plate 230 in a circular array.

[0029] In this way, by providing a plurality of soil discharge chutes 231 , the screed plate 230 can discharge excess concrete at multiple angles, thereby improving discharge efficiency and further enhancing the screed effect.

[0030] In this embodiment, Figure 1-3 As shown, a stabilizing assembly is provided in the stabilizing cavity 110 , and the stabilizing assembly is fixedly mounted on the side wall of the stabilizing cavity 110 for radially supporting the transmission rod 220 .

[0031] In this way, by setting up the stabilizing component, the transmission rod 220 can obtain support at more points when driving the screed plate 230 to rotate, avoiding braking or damage of the transmission rod 220 when the cylinder 100 moves, thereby improving the stability of use.

[0035] In this way, by setting the first fixed rod 310, the first telescopic sleeve rod 320 and the ball 360, relative sliding can occur between the first fixed rod 310 and the first telescopic sleeve, and the cushioning performance is improved. The rolling ball 360 abuts against the transmission rod 220, reducing the friction force when the transmission rod 220 is supported, and the supporting effect is better.

[0036] During implementation, the ball 360 on the first telescopic sleeve 320 abuts against the middle of the transmission rod 220 .

[0037] During implementation, the spring 350 is in a compressed state.

The cylinder 410 is installed at the top of the cylinder 100, and the control plate 420 is installed directly above the cylinder 100. The push rod of the cylinder 410 is connected to the control plate 420.

[0042] In this way, by providing the cylinder 410 and the control plate 420 , the position height of the control plate 420 can be adjusted by the cylinder 410 , and the adjustment structure is simple and has better adaptability.
