Description

Technical Field

[0001] The invention relates to the technical field of leveling devices, in particular to a high-efficiency concrete leveling device for construction engineering. Background Art

[0002] Concrete is often used in construction projects. When the concrete is processed and placed on the ground, a concrete leveling device is required.

[0003] The length of the push plate of the existing concrete leveling device is generally fixed. When the concrete leveling device is operated on concrete floors of different widths, since the length of the push plate cannot be adjusted, another concrete leveling device needs to be replaced, resulting in high construction costs. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a highly efficient concrete leveling device for construction engineering, and the specific technical scheme is as follows:

[0005] An efficient concrete leveling device for construction engineering includes a fixed component, a driving component is arranged at the bottom of the fixed component, two groups of leveling components for concrete leveling are symmetrically arranged at the bottom of the fixed component and on both sides of the driving component, and the driving component drives the longitudinal opening and closing of the two groups of leveling components to adjust the lateral length of the leveling components.

[0006] As an improvement of the above technical solution, the flattening assembly includes a first spreading plate, a second spreading plate and a rotating shaft. The rotating shafts are symmetrically arranged at both ends of the bottom of the fixed assembly and on both sides of the driving assembly. The first spreading plate and the second spreading plate are rotatably sleeved on both sides of the rotating shaft surface, and the driving assembly is rotatably connected to the first spreading plate and the second spreading plate respectively.

[0007] As an improvement of the above technical solution, the fixed assembly includes a connecting plate, a fixed plate and an annular track. A fixed plate is fixedly connected to the inside of the annular track along the longitudinal direction and at the center of the circle. A connecting plate is arranged on the top of the fixed plate. The bottoms at both ends of the fixed plate are rotatably connected to the rotating shaft, and the first spreading plate and the second spreading plate are slidably connected to the annular track.

[0008] As an improvement of the above technical solution, the fixing assembly further includes an electric push rod, and an electric push rod for adjusting the height of the annular track is arranged between the fixing plate and the connecting plate.

[0009] As an improvement of the above technical solution, the tops of the first and second spreading plates are slidably connected to the annular track via sliding sleeves, and the tops of the first and second spreading plates are provided with sliding grooves corresponding to the movement of the sliding sleeves along the annular track.

[0010] As an improvement of the above technical solution, the driving assembly includes a fixed frame, a bidirectional screw, a threaded sleeve and a connecting rod. A fixed frame is arranged at the bottom of the annular track and perpendicular to the middle of the fixed plate. A bidirectional screw is rotatably connected inside the fixed frame. Threaded sleeves are threaded on both sides of the surface of the bidirectional screw. Both sides of the threaded sleeve are rotatably connected to the first spreading plate and the second spreading plate through connecting rods.

[0011] As an improvement of the above technical solution, splash plates are provided on both sides of the surfaces of the first and second spreading plates and at the bottom of the connecting rod.

[0012] The flattening device also includes a moving vehicle, and the moving vehicle is fixedly connected to the connecting plate.

[0013] Beneficial effects of the present invention:

[0014] 1. The opening and closing degrees of the two sets of leveling components in the longitudinal direction can be adjusted simultaneously through the driving component, thereby adjusting the horizontal length of the leveling component. It can be suitable for concrete floors of different widths. There is no need to replace different leveling devices according to concrete floors of different widths, thereby reducing construction costs.

[0015] 2. At the same time, the two sets of leveling components can realize secondary leveling of the concrete floor during the movement process, thereby improving the leveling efficiency. When moving in the longitudinal direction, one set of leveling components can gather and push the excess concrete on the concrete floor to other locations, while the other set of leveling components can perform secondary leveling of the concrete bottom surface based on the leveling of the previous set, and at the same time level the concrete from the middle to both sides, thereby further preventing concrete accumulation.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figure 1 and Figure 2 As shown, Figure 1 A top view of the overall structure of the present invention; Figure 2 It is a schematic diagram of the connection structure between the driving component and the flattening component in the present invention.

[0024] An efficient concrete leveling device for construction engineering includes a fixed component 4, a driving component 3 is arranged at the bottom of the fixed component 4, two groups of leveling components 2 for concrete leveling are symmetrically arranged at the bottom of the fixed component 4 and on both sides of the driving component, and the driving component 3 drives the longitudinal opening and closing of the two groups of leveling components 2 to adjust the lateral length of the leveling components 2.

[0025] The leveling components 2 are arranged on both sides of the driving component 3. The driving component 3 can simultaneously adjust the opening and closing degree of the two groups of leveling components 2 in the longitudinal direction, thereby adjusting the horizontal length of the leveling components 2. It can be suitable for concrete floors of different widths, and there is no need to replace different leveling devices according to concrete floors of different widths. At the same time, the two groups of leveling components 2 can realize secondary leveling of the concrete floor during the movement, thereby improving the leveling efficiency. When moving in the longitudinal direction, one group of leveling components 2 can gather and push excess concrete on the concrete floor to other positions, while the other group of leveling components 2 can perform secondary leveling of the bottom surface of the concrete based on the leveling of the previous group, and at the same time, level the concrete from the middle to both sides, thereby further preventing concrete accumulation, and making the surface of the leveled concrete smoother.

[0026] Further, refer to Figure 1 and Figure 2The flattening assembly 2 includes a first flattening plate 21, a second flattening plate 22 and a rotating shaft 23. The rotating shafts 23 are symmetrically arranged at both ends of the bottom of the fixed assembly 4 and on both sides of the driving assembly 3. The first flattening plate 21 and the second flattening plate 22 are rotatably sleeved on both sides of the rotating shaft 23. The driving assembly 3 is rotatably connected to the first flattening plate 21 and the second flattening plate 22 respectively. The rotating shaft 23 is rotatably connected to the bottom of the fixed assembly 4 to limit the position of the rotating shaft 23, and then the driving assembly 3 drives the first flattening plate 21 and the second flattening plate 22 in the flattening assembly 2 to change the angle, thereby adjusting the length of the first flattening plate 21 and the second flattening plate 22 in the transverse direction. Since the two groups of flattening assemblies 2 are symmetrically arranged, the two groups of flattening assemblies 2 are respectively in a positive V-shaped structure and an inverted V-shaped structure in the longitudinal direction. The flattening assembly 2 with a positive V-shaped structure can collect and push excess concrete on the concrete floor to other positions, while the flattening assembly 2 with an inverted V-shaped structure can perform a secondary flattening on the bottom surface of the concrete on the basis of the flattening of the previous group, and at the same time flatten the concrete from the middle to both sides, further preventing concrete accumulation.

[0027] In order to improve the stability of the first and second spreading plates 21 and 22 during rotation, Figure 1 and Figure 3 The fixing assembly 4 includes a connecting plate 41, a fixing plate 42 and an annular track 43. The fixing plate 42 is fixedly connected to the inside of the annular track 43 along the longitudinal direction and through the center of the circle. The connecting plate 41 is fixedly connected to the top of the fixing plate 42. The bottoms of both ends of the fixing plate 42 are rotatably connected to the rotating shaft 23. The first spreading plate 21 and the second spreading plate 22 are slidably connected to the annular track 43. The rotating shaft 23 is limited by the two ends of the fixing plate 42. The connecting plate 41 can be used to push the flattening device to move on the concrete floor to flatten it. The annular track 43 can improve the stability of the first spreading plate 21 and the second spreading plate 22 when they are driven by the driving assembly 3.

[0028] In order to enable the leveling assembly 2 to push and level concrete piles of different heights, refer to Figure 3 The fixing assembly 4 also includes an electric push rod 44. An electric push rod 44 for adjusting the height of the annular track 43 is arranged between the fixing plate 42 and the connecting plate 41. The electric push rod 44 can drive the annular track 43 to move in the vertical direction, thereby adjusting the height of the flattening assembly 2, so as to be suitable for concrete piles of different heights.

[0029] Since the center of the first and second spreading plates 21 and 22 rotating around the rotating shaft 23 is not the same as the center of the circular track 43, Figure 2 and Figure 5Therefore, the top of the first spread plate 21 and the second spread plate 22 are slidably connected to the annular track 43 through the sliding sleeve 45, and the top of the first spread plate 21 and the second spread plate 22 is provided with a sliding groove corresponding to the movement of the sliding sleeve 45 along the annular track 43. The first spread plate 21 and the second spread plate 22 can move on the surface of the annular track 43 through the sliding sleeve 45 during the rotation process. In order to meet the needs of the movement trajectory of the first spread plate 21 and the second spread plate 22, the bottom of the sliding sleeve 45 moves inside the sliding groove opened at the top of the first spread plate 21 and the second spread plate 22.

[0030] In order to make the two sets of flattening components 2 driven at the same time and the opening and closing degrees of the two sets of flattening components 2 are the same, refer to Figure 1 and Figure 4 The driving assembly 3 includes a fixed frame 31, a bidirectional screw rod 32, a threaded sleeve 33 and a connecting rod 34. A fixed frame 31 is arranged at the bottom of the annular track 43 and perpendicular to the middle direction of the fixed plate 42. The fixed frame 31 is rotatably connected with a bidirectional screw rod 32 inside. Both sides of the surface of the bidirectional screw rod 32 are threadedly sleeved with threaded sleeves 33. Both sides of the threaded sleeve 33 are rotatably connected with the first spreading plate 21 and the second spreading plate 22 through connecting rods 34 respectively. By rotating the bidirectional screw rod 32, the bidirectional screw rod 32 drives the threaded sleeve 33 to move in directions of approaching or moving away from each other. During the movement, the threaded sleeve 33 drives the first spreading plate 21 and the second spreading plate 22 to rotate through the connecting rod 34, thereby changing the angle change between the first spreading plate 21 and the second spreading plate 22 in the longitudinal direction, thereby adjusting the change in the horizontal length of the flattening assembly 2.

[0031] In order to prevent concrete from splashing onto the connection between the connecting rod 34 and the first and second spreading plates 21 and 22, thereby affecting the flexibility of the connection between the connecting rod 34 and the first and second spreading plates 21 and 22, refer to Figure 5 Splash plates 24 are provided on both sides of the surfaces of the first spreading plate 21 and the second spreading plate 22 and at the bottom of the connecting rod 34 .

[0032] In order to reduce the labor intensity of the operator when pushing the flattening device to move, refer to Figure 1 The flattening device also includes a moving vehicle 1, which is fixedly connected to the connecting plate 41. The moving vehicle drives the flattening device to move, which greatly reduces the labor intensity of the operator.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
