Description

Technical Field

[0001] This utility model relates to the field of concrete leveling technology, and more specifically, to a pressure regulating structure for the head of a concrete leveling robot. Background Technology

[0002] In the construction industry, the smoothing process after concrete pouring is a crucial step in ensuring the flatness and quality of the concrete surface. With the continuous development of automation technology, concrete smoothing robots are gradually being widely used in various construction projects to replace traditional manual smoothing methods, thereby improving construction efficiency and smoothing quality.

[0003] Currently, there is a critical problem that urgently needs to be solved in the market for concrete smoothing robot technology. Due to the cyclical and regional characteristics of construction, there are significant differences in ambient temperature across different seasons and regions. Ambient temperature directly affects the initial setting process of concrete, resulting in noticeable differences in the degree of initial setting under the different temperature conditions of spring, summer, autumn, and winter. For example, in the hot summer, the initial setting speed of concrete is faster, and the degree of initial setting is relatively higher; while in the cold winter, the initial setting speed of concrete is slower, and the degree of initial setting is lower.

[0004] However, existing concrete smoothing robots typically have a fixed head weight, making it impossible to adapt to the initial setting stage of concrete in different seasons and ambient temperatures. The smoothing robot relies solely on its fixed counterweight to apply pressure to the concrete surface for smoothing. This fixed counterweight method makes it difficult for the robot to provide appropriate smoothing pressure when dealing with concrete at different initial setting stages. When the concrete has a high initial setting stage, the fixed counterweight may not provide sufficient pressure, resulting in poor smoothing and an inability to effectively eliminate minor undulations and unevenness on the concrete surface; conversely, when the concrete has a low initial setting stage, the fixed counterweight may be too large, causing excessive compression of the concrete surface and affecting its structural properties and surface quality. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure adjustment structure for the head of a concrete leveling robot that can adjust the pressure on the top of the leveling disc.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This utility model is further configured as follows: it includes a housing, a swing arm rotatably disposed on the top of the housing, and a smoothing disc disposed at the bottom of the swing arm. The pressure adjustment structure of the concrete smoothing robot head also includes a pressure adjustment mechanism; the pressure adjustment mechanism is disposed on the top of the swing arm; the pressure adjustment mechanism includes a first limiting part, a moving part, and a counterweight part; the first limiting part has a pair and is disposed on the top of the swing arm respectively; the moving part has a pair and is slidably disposed on the top of the pair of first limiting parts respectively; the counterweight part is disposed on the top of the moving part, and when the moving part moves toward the smoothing disc, it can drive the counterweight part to move synchronously.

[0007] By adopting the above technical solution, the problem that the initial setting degree of concrete varies due to the temperature differences in the four seasons is solved, and the smoothing robot cannot adapt to the operation requirements of the initial setting state of concrete under different working conditions by relying solely on its own counterweight. This achieves the effect of increasing the smoothing force of the smoothing disc on the concrete rotation.

[0008] The present invention is further configured such that: each of the tops of the pair of first limiting parts is provided with a horizontal sliding groove for limiting the movement of the moving part, and the horizontal sliding groove is a cuboid structure.

[0010] The present invention is further configured such that: the pressure regulating mechanism also includes a rotating shaft; the rotating shaft is disposed in the middle of a pair of rotating teeth, and the two sides of the rotating shaft pass through the outer sides of a pair of positioning plates respectively, so that when the rotating shaft rotates, it can drive the pair of rotating teeth to rotate synchronously.

[0011] The present invention is further configured such that: the pressure regulating mechanism also includes a rotary handle; the rotary handle has a pair and is respectively rotatably disposed on the outside of a pair of positioning plates, and the end face of the pair of rotary handles is fixedly connected to the side of the rotating shaft, so that when the rotary handle rotates, it can drive the rotating shaft and the rotating gear to rotate synchronously.

[0012] The present invention is further configured such that: the pressure regulating mechanism also includes a rotating part; the rotating part is rotatably disposed on the outside of the rotating handle.

[0013] In summary, this application includes at least one of the following beneficial technical effects: By setting up a pressure regulating mechanism, the problem of the smoothing robot being unable to adapt to the different initial setting states of concrete due to seasonal temperature differences was solved. This achieved the effect of increasing the smoothing force of the smoothing disc on the concrete rotation. Attached Figure Description

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: Example 1: In order to solve the problem that when pouring concrete for building construction, the initial setting degree of concrete varies due to different seasonal temperatures, and the weight of the smoothing robot head cannot be adjusted sequentially, it is difficult to adapt to the operational needs of different initial setting states of concrete in different seasons and ambient temperatures by relying solely on its own weight.

[0018] The concrete leveling robot head pressure adjustment structure includes a housing 1, a swing arm 2 rotatably mounted on the top of the housing 1, and a smoothing disc 3 mounted on the bottom of the swing arm 2. The pressure adjustment mechanism 4 is also located on the top of the swing arm 2. The pressure adjustment mechanism 4 includes a first limiting part 41, a moving part 42, and a counterweight part 43. There is a pair of first limiting parts 41, which are respectively mounted on the top of the swing arm 2. There is a pair of moving parts 42, which are respectively slidably mounted on the top of the pair of first limiting parts 41. The counterweight part 43 is mounted on the top of the moving part 42. When the moving part 42 moves toward the smoothing disc 3, it can drive the counterweight part 43 to move synchronously.

[0019] In this embodiment, the top of the moving part 42 is welded to the bottom of the counterweight part 43 using a shim. When faced with a situation where it is necessary to increase the rotational smoothing force of the smoothing disc 3 on the concrete, the weight of the counterweight part 43 can be increased, thereby increasing the overall weight of the smoothing disc 3 and achieving the purpose of increasing the rotational smoothing force of the smoothing disc 3. This solves the problem that due to the different initial setting degrees of concrete caused by seasonal temperature differences, the smoothing robot cannot adapt to the operational needs of different concrete initial setting states by relying solely on its own counterweight, thus achieving the effect of increasing the rotational smoothing force of the smoothing disc 3 on the concrete.

[0020] See Figures 2-4 Each of the first limiting parts 41 has a horizontal sliding groove on its top for limiting the movement of the moving part 42, and the horizontal sliding groove has a cuboid structure.

[0021] In this embodiment, in order to ensure that the counterweight 43 and the moving part 42 can move stably under the restriction of the first limiting part 41, a horizontal sliding groove is provided on the top of each pair of first limiting parts 41 to restrict the movement of the moving part 42, so that the moving part 42 can move stably through the horizontal sliding groove when it moves.

[0022] See Figure 5 The pressure regulating mechanism 4 also includes a positioning plate 44, a rotating tooth 45, and a toothed plate 46; the positioning plate 44 has a pair and is respectively disposed on both sides of the swing arm 2; the rotating tooth 45 has a pair and is respectively rotatably disposed on the side of the positioning plate 44, and both of the rotating teeth 45 are located below the counterweight part 43; the toothed plate 46 has a pair and is respectively disposed at the bottom of the counterweight part 43, and both of the toothed plates 46 are located at the top of the pair of rotating teeth 45, and the rotating teeth 45 mesh with the toothed plate 46.

[0023] In this embodiment, to adjust the pressure of the smoothing disc 3 by driving the moving part 42 and the counterweight part 43 to move under the restriction of the first limiting part 41, the rotating tooth 45 first rotates. When the rotating tooth 45 rotates, it can move the meshing toothed plate 46. Since the toothed plate 46 is fixedly connected to the bottom of the counterweight part 43, when the toothed plate 46 is driven by the rotation of the rotating tooth 45, it can drive the counterweight part 43 and the moving part 42 to move closer to or away from the bottom of the first limiting part 41.

[0024] See Figures 3-4 The pressure regulating mechanism 4 also includes a rotating shaft 47; the rotating shaft 47 is located in the middle of a pair of rotating teeth 45, and the two sides of the rotating shaft 47 pass through the outer sides of a pair of positioning plates 44 respectively. When the rotating shaft 47 rotates, it can drive the pair of rotating teeth 45 to rotate synchronously.

[0025] In order to drive a pair of rotating teeth 45 to rotate synchronously, the rotating shaft 47 first rotates, which in turn drives the pair of rotating teeth 45 to rotate synchronously.

[0026] See Figures 3-4 The pressure regulating mechanism 4 also includes a rotary handle 48; the rotary handle 48 has a pair and is respectively rotatably disposed on the outside of a pair of positioning plates 44, and the end faces of the pair of rotary handles 48 are fixedly connected to the side of the rotary shaft 47. When the rotary handle 48 rotates, it can drive the rotary shaft 47 and the rotary gear 45 to rotate synchronously.

[0027] In this embodiment, in order to facilitate the rotation of the rotating shaft 47 and the rotating gear 45, the operator first operates the rotating handle 48 and drives the rotating handle 48 to rotate. When the rotating handle 48 rotates, it can drive the rotating shaft 47 and the rotating gear 45 to rotate synchronously.

[0028] See Figures 2-3 The pressure regulating mechanism 4 also includes a rotating part 49; the rotating part 49 is rotatably disposed on the outside of the rotating handle 48.

[0029] In this embodiment, a rubber anti-slip sleeve can be provided on the outer side of the rotating part 49 to facilitate the rotation of the rotating handle 48.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
