Technical Field

[0001] The present invention relates to the technical field of pipe segment cleaning, and more specifically, to a cleaning device for a tunnel pipe segment. Background Art

[0002] Shield construction is widely used in the construction of urban subway tunnels. As a large-scale mechanical equipment for underground construction, the shield construction process includes several basic links such as soil excavation, soil transportation, and segment assembly. Tunnel segments are prefabricated concrete components, which are mainly used to form the lining structure of the tunnel to form a permanent structure that supports the surrounding soil and groundwater pressure. The segments are usually annular structures composed of multiple parts, and multiple segments are spliced ​​together to construct the internal contour of the entire tunnel.

[0003] The molding quality of the segments is an important part of evaluating the quality of tunnel excavation, and the cleanliness of the molded segments is also an important reference standard for the molding quality of the segments, so the inner walls of the segments will be cleaned.

[0004] Traditional segment cleaning is often done by temporarily flushing the segments before assembling them, and there is no fixed cleaning time, so the cleaning quality of the segments is difficult to guarantee.

The dirt on the segment can be further cleaned by the rotation of the roller brush 72. The tunnel segment can be effectively cleaned by the high-pressure nozzle 74 and the roller brush 72, and the cleaning quality of the segment is improved to a certain extent.

[0064] In this embodiment, preferably, please refer to Figure 3-5 and Figure 7-10A rotating shaft 10 is rotatably provided on the adapter seat 71, and the rotating shaft 10 is transmission-connected to the motor built into the adapter seat 71.

A socket 13 adapted to the socket 11 is opened at the end of the mounting column 12, and a mounting assembly 14 is provided on the socket 11 for connecting the socket 11 and the mounting column 12.

[0065] When installing the roller brush 72, the socket 11 can be slid along the rotating shaft 10 first, that is, the distance between the sockets 11 on both sides becomes larger, and then the roller brush 72 is placed between the sockets 11 on both sides, and then the socket 11 is aligned with the position of the socket 13 of the mounting column 12 on the roller brush 72. After gradually loosening the socket 11, the socket 11 will be inserted into the socket 13, and finally the socket 11 and the mounting column 12 are connected through the mounting assembly 14, and the installation of the roller brush 72 can be completed; when disassembling, the connection between the socket 11 and the mounting column 12 can be released through the mounting assembly 14, and then the socket 11 is driven to slide along the rotating shaft 10, so that the socket 11 is separated from the socket 13 of the mounting column 12, and then the roller brush 72 can be removed. Therefore, through the detachable design of the roller brush 72, the installation and disassembly of the roller brush 72 can be realized simply and quickly, and then the roller brush 72 can be easily cleaned or replaced, saving time and effort, and ensuring that the roller brush 72 has sufficient cleaning performance and strong flexibility.

The first elastic member 16 in the present application can be a spring, and when the socket 11 is made to slide along the rotating shaft 10, the retaining block 18 will slide along the retaining groove 17 and compress the first elastic member 16. When the socket 11 is subsequently released, the socket 11 can be driven to reset through the first elastic member 16. At the same time, the socket 11 can be limited by the blocking of the retaining block 18 to prevent the socket 11 from being separated from the rotating shaft 10.

[0067] In this embodiment, preferably, please refer to Figure 8-10 The inner wall of the jack 13 is provided with a limiting groove 19, and the mounting assembly 14 includes:

When the socket 11 is inserted into the socket 13, the limit block 142 will be squeezed by the inner wall of the socket 13, and the limit block 142 will gradually move into the inner hidden groove 141 and compress the second elastic member 143. When the socket 11 is inserted into the bottom wall of the socket 13, the limit block 142 is in the position of the limit groove 19. After the limit block 142 is no longer compressed, the limit block 142 can be driven to reset by the second elastic member 143. At this time, the limit block 142 will enter the limit groove 19, and the connection between the socket 11 and the mounting column 12 can be realized.

[0071] Afterwards, the limiting block 142 can be driven to gradually move into the inner recessed groove 141 by releasing the assembly 144, and the limiting block 142 is separated from the limiting groove 19.
