[0024] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figures 1-3 , Figure 9 As a specific implementation method, the technical solution of this utility model is as follows: an improved device for cleaning the bedrock surface of a tunnel is provided, including a second connecting member 2 and a cleaning component. The second connecting member 2 is used to connect the cleaning component and the robotic arm 1. The cleaning component includes a first connecting member 31 that is detachably connected to the second connecting member 2. A wire brush head 35 is provided at the end of the first connecting member 31 away from the second connecting member 2.

[0026] For details, please refer to Figure 9 The second connecting piece 2 is connected to the robotic arm 1, which is the robotic arm 1 of the excavator. The connection method between the second connecting piece 2 and the robotic arm 1 is the same as the existing connection method between the excavator backhoe and the robotic arm 1. The specific connection method will not be described in detail here. At the end of the second connecting piece 2 away from the connection with the robotic arm 1, there are two first mating holes 20. The first mating holes 20 are used to connect with the first connecting piece 31 of the cleaning component. (Refer to...) Figures 1-3 The specific structure of the first connecting member 31 includes two rigid plates spaced apart. The ends of the two rigid plates are welded with a first connecting plate 32. Each of the two rigid plates is provided with two second mating holes 310. When the first connecting member 31 is connected to the second connecting member 2, the two rigid plates are set on both sides of the second connecting member 2. Then, a pin is used to pass through the second mating hole 310, the first mating hole 20 and the second mating hole 310 in sequence, thereby realizing the connection between the first connecting member 31 and the second connecting member 2. Multiple wire brush heads 35 are provided on the side of the first connecting plate 32 away from the two rigid plates. With the above arrangement, when cleaning the excavated bedrock surface, the excavator is operated and the wire brush heads 35 are used to quickly clean the loose debris on the foundation surface, realizing mechanized construction and greatly improving construction efficiency. According to statistics, at least 5 manpower can be reduced for every 100㎡ of foundation surface cleaning.

[0027] Specifically, in practical applications, the wire brush head 35 can be made from cut pieces of scrap steel wire rope from construction sites, which can make use of waste and reduce usage costs.

[0028] Furthermore, as a specific implementation, the first connector 31 is provided with a first connecting plate 32, and a second connecting plate 33 is detachably connected to the first connecting plate 32. The wire brush head 35 is disposed on the second connecting plate 33. To facilitate subsequent replacement and maintenance of the wire brush head 35, as a preferred embodiment, refer to... Figure 3 , Figure 4 The first connecting plate 32 is detachably and fixedly connected to the second connecting plate 33, and the wire brush head 35 is set on the second connecting plate 33. This arrangement makes it easy to separate the second connecting plate 33, which is equipped with multiple wire brush heads 35, from the first connecting plate 32. After separation, it is easy to replace and maintain the wire brush head 35. Multiple second connecting plates 33 can be set, each equipped with a wire brush head 35, to form a quick-replaceable brush head assembly. During construction, the second connecting plate 33 can be disassembled and the brush head assembly can be quickly replaced, which is conducive to rapid construction. The replaced brush head assembly can be used to replace and maintain the wire brush head 35 separately. Specifically, the first connecting plate 32 and the second connecting plate 33 can be detachably and fixedly connected by bolts.

[0029] Furthermore, as a specific embodiment, a partition 333 is perpendicularly arranged on the side of the second connecting plate 33 opposite to the first connecting plate 32. Multiple wire brush heads 35 are arranged on both sides of the partition 333, and the multiple wire brush heads 35 are spaced apart along the surface direction of the partition 333. (Reference) Figures 4-6 A partition 333 is vertically arranged on the second connecting plate 33. The partition 333 extends along the axis of the second mating hole 310 and is located in the middle area of ​​the second connecting plate 33. Multiple wire brush heads 35 are arranged on both sides of the partition 333, thereby forming two layers of brush heads. The two layers of brush heads can provide a better cleaning effect, and the two layers of brush heads are supported by the partition 333, which can provide a better support effect for the brush heads and make the brush heads have a better cleaning effect.

[0030] Furthermore, a plurality of positioning posts 331 are spaced apart on the partition plate 333, and each positioning post 331 has a positioning arc surface 370 coaxially arranged on the side near the first plate; and the distance between the axes of two adjacent positioning posts 331 is equal to twice the radius of the positioning arc surface 370. As a specific embodiment, a plurality of positioning posts 331 are evenly spaced on the partition plate 333. The positioning posts 331 can be inserted into the partition plate 333 and then fixed by welding, so that the lengths extending from both ends of the partition plate 333 are equal. A positioning arc surface 370 is provided on one side of the positioning post 331. With this arrangement, [reference needed] Figure 5 When setting the wire brush head 35, a suitable length of wire rope can be cut, and the middle position of the wire rope is wound around the positioning post 331 and positioned by the positioning arc surface 370, which facilitates the uniform and orderly arrangement of the wire brush head 35. Then, the wire rope is pressed by the pressure plate 36 to form the wire brush head 35. This method facilitates the arrangement of the wire brush head 35 and also facilitates the replacement of the wire brush head 35 later.

[0031] Furthermore, as a specific implementation method, refer to Figure 5 , Figure 6 The partition 333 is detachably fitted with a positioning element 37, and the positioning arc surface 370 is disposed on the positioning element 37. Specifically, the partition 333 is provided with a plurality of second threaded holes 3330 at intervals. The positioning element 37 is made of steel plate and is provided with a plurality of countersunk through holes 360 corresponding to the second threaded holes 3330. It is detachably fixed to the partition 333 by bolts. In this way, when the wire brush head 35 is disassembled later, the positioning element 37 can be loosened together, and the positioning element 37 can be disassembled together with the wire brush head 35, which is more conducive to the disassembly of the wire brush head 35.

[0032] Furthermore, as a specific implementation, a pressure plate 36 is detachably fixedly provided on the side of the positioning member 37 away from the partition 333. Specifically, refer to... Figure 5 , Figure 6Located on the plate surface of partition 333, on the side of positioning post 331 away from the second connecting plate 33, a support platform 332 is provided corresponding to each positioning post 331. The width of the support platform 332 is equal to the diameter of the positioning post 331, and the height of the support platform 332 is lower than the height of the positioning post 331. The height of the support platform 332 is equal to or slightly smaller than the diameter of the wire brush head 35, generally 1-3 mm smaller than the diameter of the wire head. When the positioning member 37 is set on partition 333, the plate surface of the positioning member 37 away from partition 333 is on the same plane as the end of positioning post 331. The top surface of support platform 332 is provided with a first threaded hole 3320. Pressure plate 36 is provided with a pressing surface 364 that abuts against the top surface of support platform 332. Pressure plate 36 is also provided with multiple through holes 360 corresponding to multiple first threaded holes 3320. The pressure plate 36 is pressed by bolts to the first threaded holes 3320, thereby pressing and positioning the wire brush head 35. (Reference) Figure 7 The pressure plate 36 has a groove 363 on the side opposite to the pressing surface 364. A through hole 360 ​​is provided at the bottom of the groove 363. The groove 363 can accommodate the bolt head, which facilitates the subsequent installation of the shielding curtain 34.

[0033] Furthermore, as a specific implementation method, refer to Figure 8 The pressure plate 36 is provided with positioning blind holes 365 that correspond one-to-one with the multiple positioning posts 331. Specifically, the pressure plate 36 also includes a positioning surface 362 corresponding to the positioning member 37, and a positioning blind hole 365 is provided on the pressing surface 364. With this arrangement, when the pressure plate 36 is installed, the ends of the positioning posts 331 can be inserted into the positioning blind holes 365 to position the pressure plate 36. After the pressure plate 36 is pressed by bolts, the positioning surface 362 can contact the positioning member 37 to support the pressure plate 36 and improve the stability of the pressure plate 36.

[0034] Furthermore, as a preferred embodiment, refer to Figures 4-8 Both sides of the partition 333 are provided with side plates 330, and the side of the pressure plate 36 opposite to the partition 333 is provided with a shielding curtain 34. Specifically, the shielding curtain 34 is made of rubber, the partition 333 is made of steel plate welded to the second connecting plate 33, the pressure plate 36 is provided with a third threaded hole 361, and the shielding curtain 34 is locked in the third threaded hole 361 by bolts. The shielding curtain 34 and the side plates 330 can shield the wire brush head 35, and can block the debris brushed off by the wire brush head 35 during construction, reduce the range of debris scattering, and improve safety.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
