Description

Technical Field

[0001] The utility model relates to the field of construction engineering equipment, in particular to a concrete floor cutting seam cleaning piece. Background Art

[0002] For concrete floors, after concrete pouring, cutting joints, i.e. expansion joints, will be opened at equal intervals. The purpose is to ensure that the concrete floor will not crack when it expands due to heat. Separating the concrete floor at equal intervals can release the expansion force between adjacent concretes to avoid cracking of the concrete floor. Concrete floors are particularly common in rural environments, but the internal space of their cutting joints is easily filled, especially some rock particles will occupy a large space of the cutting joints after filling. At the same time, in the process of continuous use and rolling of the concrete floor, the concrete will also expand and extend, thereby reducing the spacing between the cutting joints of adjacent concretes. In addition, the filling of rock particles can easily cause cracking due to heat in hot weather, which is not conducive to the long-term use of concrete floors.

[0003] Based on the above problems, a concrete floor cutting seam cleaning piece is provided, which can facilitate the cleaning of the concrete floor cutting seam, thereby ensuring that when the concrete road is used for a long time, there is still space for releasing the expansion force to avoid cracking of the concrete road. Utility Model Content

[0004] The utility model aims to provide a concrete floor cutting seam cleaning piece, which can ensure that workers can conveniently clean the cutting seam debris in the concrete floor, thereby providing a space for the concrete road to expand due to heat, thereby avoiding the problem of expansion and cracking of the concrete road due to heat.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A concrete floor cutting seam cleaning piece comprises a gripping rod and a scraping end, wherein the scraping end is arranged at the front end of the gripping rod; the scraping end comprises a hooking portion and an expansion portion, wherein the hooking portion and the expansion portion are smoothly connected, and the scraping end generates a force on debris inside the cutting seam by pulling the gripping rod, thereby cleaning the debris.

[0007] The hooking portion includes a conical tip end and a curved shielding portion, the conical tip end and the curved shielding portion are continuously connected, and the thickness of the conical tip end is greater than the thickness of the curved shielding portion.

[0008] The expansion portion includes a groove shielding position and a shielding expansion plate. The groove shielding position is continuously connected to the arc surface shielding position. The shielding expansion plate is arranged at the rear end position of the groove shielding position.

[0010] The gripping rod is hingedly connected to the scratching end, and the relative positions of the gripping rod and the scratching end are fixed by a fixing bolt.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When the device is set up, the grip rod and the scratch end are set up, and the grip rod is pulled to make the scratch end generate force on the debris inside the cutting seam to clean up the debris.

[0019] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0020] When cutting debris inside the cutting seam of the concrete floor, the following issues need to be considered:

[0021] 1. It is necessary to loosen and detach the debris in the cutting seam, because the debris that is blocked and accumulated in the cutting seam may clump and stick together under the external force over time. Therefore, if the debris is directly pulled out, a lot of force is required, especially for some gravel that enters the cutting seam. It is easy to get stuck in the cutting seam, making it inconvenient to remove it from the cutting seam.

[0022] 2. It is necessary to ensure that the debris in the cutting seam can be effectively removed from the cutting seam after loosening it. Because the cutting seam size of the concrete floor is small, it is necessary to effectively remove the debris in the cutting seam after loosening it, otherwise the debris will accumulate inside the cutting seam again, and the cleaning operation of the debris inside the cutting seam cannot be effectively completed.

[0023] 3. Now, when some sanitation workers clean up the debris in the cutting seam, they often use a shovel to clean up the debris in the cutting seam. This method is not only not good in cleaning effect, but also causes wear to the adjacent concrete floor. Moreover, the surrounding concrete floor will hinder the normal cleaning of the debris in the cutting seam, which is not conducive to the normal cleaning operation of the debris in the cutting seam.

[0024] Therefore, in order to solve the above problems, a concrete floor cutting seam cleaning device is provided: it includes a grip rod and a scratch end 1, and the scratch end 1 is arranged at the front end of the grip rod; the scratch end 1 includes a hook part 2 and an expansion part 3, and the hook part 2 and the expansion part 3 are smoothly connected. By pulling the grip rod, the scratch end 1 generates a force on the debris inside the cutting seam, so that the debris is cleaned.

[0025] The purpose of the hook portion 2 is as follows:

[0026] Because debris will accumulate in the cut seam of the concrete floor, the debris in the cut seam will be hardened and attached to the concrete, which makes it inconvenient to clean the debris normally. The hook part 2 is first in contact with the debris in the cut seam, and at the same time, it can give the debris enough force, so that the hook part 2 is effectively inserted into the inner position of the cut seam. When in use, as long as the hook part 2 is inserted into the deep position of the cut seam, and then the grip is pulled, the debris inside the cut seam can be loosened, thereby facilitating the subsequent cleaning operation of the debris in the cut seam.

[0027] The purpose of the expansion part 3 is as follows:

[0028] On the basis of the hook part 2, when the hook part 2 is moved along the cutting seam direction by pulling the handle, the hook part 2 can loosen the debris in the cutting seam. Because the hook part 2 and the expansion part 3 are smoothly connected, the soil hooked by the hook part 2 is brought into the expansion part 3, and at the same time follows the position of the scraping end 1. The debris is accumulated at the expansion part 3 and expands outward, so that the cleaned debris is separated from the cutting seam, thereby realizing the cleaning operation of the debris inside the cutting seam. Here, when setting the hook part 2 and the expansion part 3, the width of the expansion part 3 should meet the width of the cutting seam as much as possible, so as to avoid the problem of jamming between the expansion part 3 and the inner wall of the cutting seam when the handle is pulled to drive the scraping end 1 to move.

[0029] The hooking part 2 and the expansion part 3 are specifically configured and optimized:

[0030] The hooking part 2 includes a conical tip end 4 and a curved shielding position 5, wherein the conical tip end 4 is connected to the curved shielding position 5, and the thickness of the conical tip end 4 is greater than the thickness of the curved shielding position 5. The conical tip end 4 is provided to reduce the force area, so that a greater pressure can be applied to the debris, thereby facilitating the loosening of the debris in the cutting seam; at the same time, after the debris in the cutting seam is loosened by the conical tip end 4, the curved shielding position 5 is required to shield the loosened debris, so as to prevent the debris loosened by the conical tip end 4 from escaping from the scratching end 1 when the scratching end 1 moves, and re-entering the cutting seam after the scratching end 1 moves, so as to ensure that the debris in the cutting seam is effectively cleaned. At the same time, the thickness of the conical tip end 4 is increased here, so that the conical tip end 4 can act on the deeper cutting seam debris, making the debris cleaning more thorough.

[0031] The expansion part 3 includes a groove shielding position 6 and a shielding expansion plate 7. The groove shielding position 6 is connected to the arc shielding position 5; the shielding expansion plate 7 is arranged at the rear end of the groove shielding position 6. Because the debris is pushed by the arc shielding member after the debris is removed by the conical tip end 4; therefore, the groove shielding position 6 can cover the loose debris, and the shielding position is set in the shape of a groove, which can limit the debris while allowing the debris to be pushed upward under the squeeze force, and then pushed to the shielding expansion plate 7 position. At the same time, the shielding expansion plate 7 is a curved surface structure, and the arc surface of the shielding expansion plate is opened toward the two sides of the scratching end 1; and then the debris blocked by the shielding expansion plate 7 is sent to the two sides of the cutting seam through the shielding expansion plate 7, thereby realizing the task of quickly cleaning the debris in the cutting seam.

[0032] The grip rod is hingedly connected to the scratch end 1, and the relative positions of the grip rod and the scratch end 1 are fixed by a fixing bolt so as to adjust the inclination angle between the scratch end 1 and the grip rod to accommodate users of different heights.

[0033] Therefore, a concrete floor cut seam cleaning piece can ensure that workers can conveniently clean the cut seam debris in the concrete floor, thereby providing space for the concrete road to expand due to heat, thereby avoiding the problem of expansion and cracking of the concrete road due to heat.
