[0030] like Figure 4 As shown, the base includes a bearing plate 2 and two bearing bars 1 arranged parallel to each other, wherein both ends of the bearing plate 2 are respectively connected to the two bearing bars 1, and a first locking hole 21 is provided on the bearing plate 2. In order to improve the structural strength of the base, a support plate 13 may be further provided under the bearing plate 2, and the bottom ends of the two bearing bars 1 should be connected to the top surface of the support plate 13, so as to prevent the base from being deformed during use.

[0031] In order to realize the assembly between the base and the engineering machinery, an assembly plate 3 is provided on the side wall of the bearing bar 1 away from the bearing plate 2, and an assembly hole 31 is provided on the assembly plate 3. During assembly, the staff can insert bolts into the assembly holes 31 and fix the base to the preset mounting seat on the engineering machinery through the bolts.

[0032] In this embodiment, the first clamping plate 4 and the second clamping plate 5 are both arranged on the base in a detachable connection manner, wherein the second clamping plate 5 is installed on the bearing bar 1 by bolts, the first clamping plate 4 is arranged above the second clamping plate 5, and a clamping gap for fixing the cleaning unit is formed between the first clamping plate 4 and the second clamping plate 5. In order to realize the detachable connection between the first clamping plate 4 and the base, a slidable connecting member is provided on the bearing bar 1. During assembly, the staff can install the first clamping plate 4 on the connecting member so as to control the opening and closing of the clamping gap by moving the first clamping plate 4 when installing the cleaning unit. In addition, in order to facilitate locking the position of the first clamping plate 4 and prevent the first clamping plate 4 from moving abnormally after completing the clamping of the cleaning unit, a locking plate 41 can also be provided on the first clamping plate 4, and a second locking hole 411 should be provided on the locking plate 41, and a locking bolt 412 is provided inside the second locking hole 411. After the cleaning unit is assembled, the staff can insert the bottom end of the locking bolt 412 into the first locking hole 21 and tighten it with the help of a nut, so that the first clamping plate 4 can form a good clamping and fixing effect on the cleaning unit.

[0033] Optionally, the connecting member in this embodiment may include a limit block 91 and a connecting screw 92. Figure 4 and Figure 5As shown, in order to realize the assembly between the bearing bar 1, the connecting member and the first clamping plate 4, a connecting hole 42 should be provided on the first clamping plate 4, a receiving cavity 11 should be provided inside the bearing bar 1, and a guide cutout 12 connected to the receiving cavity 11 is provided on the side wall of the bearing bar 1 close to the cleaning unit.

[0034] In addition, to prevent the connection piece from separating from the load-bearing bar 1, the width of the stopper 91 should be greater than the width of the guide notch 12. When the cleaning unit fixed inside the clamping gap is subjected to a load, the end surface of the stopper 91 will abut against the inner side wall of the accommodating cavity 11, thereby preventing the connection piece from separating from the load-bearing bar 1.

[0035] In the actual working process, since the sizes of the base surfaces to be cleaned for different continuous walls may be different, in order to facilitate the cleaning unit in the present device to match the base surfaces of different sizes to be processed, the cleaning unit should include multiple cleaning components. Before use, the staff can select the number of cleaning components to be loaded into the clamping gap according to the width of the base surface to be processed, so that the overall width of the cleaning unit is the same as the width of the base surface to be processed, thereby improving the working efficiency of the base surface cleaning. When the width of the base surface to be processed is greater than the current width of the first clamping plate 4 and the second clamping plate 5, the staff can also disassemble and replace the first clamping plate 4 and the second clamping plate 5 to increase the capacity of the clamping gap and facilitate the installation of more cleaning components into the clamping gap.

During assembly, the staff can insert the positioning plate 61 into the clamping gap, and clamp and fix the positioning plate 61 by the first clamping plate 4 and the second clamping plate 5 to ensure that the cleaning assembly moves synchronously with the base.

[0037] Optionally, in order to improve the installation reliability of the cleaning assembly, a first positioning protrusion 611 and a second positioning protrusion 612 may be provided on the top and bottom surfaces of the positioning plate 61, respectively. Accordingly, a plurality of first positioning holes 43 for accommodating the first positioning protrusion 611 should be provided on the first clamping plate 4, and a plurality of second positioning holes 51 for accommodating the second positioning protrusion 612 should be provided on the second clamping plate 5. When the positioning plate 61 enters the interior of the clamping gap, the first positioning protrusion 611 and the second positioning protrusion 612 will be inserted into the first positioning hole 43 and the second positioning hole 51, respectively, so as to prevent the cleaning assembly from being separated from the clamping gap by means of the cooperation between the positioning protrusion and the positioning hole.

[0038] In order to realize the assembly between the brush head 7 and the connecting plate 6, a first mounting hole may be provided on the brush head 7, and a mounting bolt 72 may be provided inside the first mounting hole. Correspondingly, a mounting plate 62 may be provided on the side wall of the connecting plate 6 away from the base, and a second mounting hole 621 may be provided on the mounting plate 62. During assembly, the staff may insert the mounting bolt 72 into the second mounting hole 621 and tighten it with a nut, so that the brush head 7 is fixed on the mounting plate 62.

[0039] As an optional implementation of this embodiment, in order to improve the scraping effect of the scraper 8 on the attachments, an angle of 30°-60° may be formed between the plane where the scraper 8 is located and the plane where the connecting plate 6 is located.

[0040] In addition, in order to improve the structural strength of the area where the scraper 8 and the brush head 7 are located, a first reinforcing rib 81 connected to the connecting plate 6 may be provided on the side wall of the scraper 8, and a second reinforcing rib 622 connected to the connecting plate 6 may be provided on the mounting plate 62, so that the scraper 8 is supported by the first reinforcing rib 81, and the mounting plate 62 is supported by the second reinforcing rib 622.

[0041] The effects of the above scheme are described below:

[0042] The present embodiment provides an underground continuous wall base cleaning device, wherein the cleaning unit includes a plurality of cleaning components which are clamped and fixed by a first clamping plate and a second clamping plate, so that the staff can select the number of cleaning components to be installed inside the clamping gap according to actual needs, so that the overall width of the cleaning unit matches the width of the base surface to be processed. Secondly, the present device can disassemble and replace the first clamping plate and the second clamping plate, so it can be easily adapted to different types of work requirements. In addition, the present device can enhance the fixing effect of the clamping gap on the cleaning component by cooperating with the positioning protrusion and the positioning hole, and can prevent the connection member from being separated from the bearing bar by the guide cutout and the limit block, so it has a higher structural reliability.
