Description

Technical Field

[0001] This utility model is a random segment flushing system for tunnel boring machines, belonging to the field of tunnel boring equipment. Background Technology

[0002] During subway tunnel construction, mud and mortar splash onto the tunnel segments during processes such as conveyor belt transport of sludge and excavated soil, grouting, and pipe washing, affecting the appearance quality of the finished tunnel. Traditional flushing methods involve workers directly washing the segments with high-pressure water hoses. This method requires operation only after tunneling has stopped, and due to limited water pressure, it is difficult to clean the tunnel ceiling and concealed areas, increasing the difficulty of later construction. Therefore, to improve construction efficiency, an automated random flushing system that can be operated from a control room is adopted. This method requires no specific personnel on duty and eliminates the need for handheld high-pressure water hoses. The tunnel boring machine operator directly operates a specific system to flush the tunnel segments based on the progress of tunneling, greatly improving construction efficiency.

[0003] Therefore, in order to address the above problems, a random segment flushing system for tunnel boring machines is proposed to solve these problems. Utility Model Content

[0028] Please see Figures 1-5 This utility model provides a technical solution for a random segment washing system for a tunnel boring machine (TBM), including a circumferential high-pressure washing device 1. The circumferential high-pressure washing device 1 is arranged around the trolley 3 and is connected to the trolley 3 via a longitudinal sliding device 2. Two bottom high-pressure washing devices 4 are symmetrically arranged on both sides of the inner bottom of the circumferential high-pressure washing device 1, and the bottom high-pressure washing devices 4 are located below the trolley 3. This washing system moves the washing devices longitudinally via the longitudinal sliding device 2. The circumferential high-pressure washing device 1 washes the surface of the tunnel segments, while the bottom high-pressure washing devices 4 can be rotated and the angle of the high-pressure nozzles 401 can be adjusted by two sets of rotating motors. This allows the entire washing system to complete the washing of the entire tunnel segments, ensuring the appearance quality of the tunnel and reducing the input of personnel, machinery, and materials due to substandard appearance quality, thereby reducing construction costs.

The circumferential high-pressure flushing device 1 is circular in shape and located between the trolley 3 and the pipe segment. The high-pressure nozzle 401 is perpendicular to the outer wall of the pipe segment and is connected to the high-pressure water pipe of the trolley 3 to achieve circumferential flushing of the pipe segment surface. Through the design of the circumferential high-pressure flushing device 1, and through the cooperation of the high-pressure nozzle 101 and the circumferential high-pressure stainless steel water pipe 102, the high-pressure water flow can be spread outward through the circumferential high-pressure stainless steel water pipe 102 and the high-pressure nozzle 101 by connecting the high-pressure water pipe of the trolley 3, thereby achieving circumferential flushing of the pipe segment surface.

[0030] See Figure 5The longitudinal sliding device 2 includes a sliding outer shell 203. One side of the outer surface of the sliding outer shell 203 is connected and fixed to the circumferential high-pressure flushing device 1. A drive motor 201 is installed on the side of the sliding outer shell 203. The output end of the drive motor 201 passes through the interior of the sliding outer shell 203 and is connected to a gear. The gear is located in a movable groove opened on one side of the sliding outer shell 203. One side of the movable groove is connected to a sliding groove. The sliding outer shell 203 is slidably sleeved on the slide rail 202 through the sliding groove. The slide rail 202 is fixed on the trolley 3. A rack is fixed on the slide rail 202. The gear meshes with the rack. Through the design of the longitudinal sliding device 2, the drive motor 201 can drive the gear to rotate. The gear meshes with the rack fixed on the slide rail 202, thereby driving the longitudinal sliding device 2 to move and realize the longitudinal movement of the high-pressure flushing device 1, completing the flushing of the pipe segments within a certain longitudinal range.

[0031] See Figures 2-4 The bottom high-pressure flushing device 4 includes a second rotating motor 405 fixed to the outer surface of the sliding outer shell 203. The output end of the second rotating motor 405 is fixedly connected to an outer steel casing 403. The outer circumferential surface of the outer steel casing 403 has several evenly spaced movable openings, each a 180-degree arc opening. A high-pressure stainless steel pipe 402 is rotatably connected inside the outer steel casing 403. Several high-pressure nozzles 401 are evenly installed on the outer circumferential surface of the high-pressure stainless steel pipe 402. The high-pressure nozzles 401 penetrate through the movable openings to the outside of the outer steel casing 403. One end of the outer surface of the high-pressure stainless steel pipe 402 is connected to a first rotating motor 404 fixed to the side of the outer steel casing 403. The outer surface of the first rotating motor 404 has a motor housing. A high-pressure water supply pipe 406 is located inside the motor housing on one side. One end of the 6 is connected to the high-pressure stainless steel pipe 402, and the other end of the high-pressure water supply pipe 406 is connected to the high-pressure water inlet of the trolley 3. Both ends of the high-pressure stainless steel pipe 402 that are in contact with the inner wall of the outer steel casing 403 are provided with high-pressure stainless steel pipe rotating bearings 407 to reduce wear between the high-pressure stainless steel pipe 402 and the outer steel casing 403. The bottom high-pressure flushing device 4 is symmetrically arranged at the bottom of the trolley 3. It can be rotated by rotating motor 2 405 without affecting the passage of the battery vehicle. When the bottom high-pressure flushing device 4 is rotated to be parallel to the tunneling direction, the angle of the high-pressure nozzle 401 is adjusted by rotating motor 1 404 to complete the flushing of the bottom segments of the walkway on both sides of the trolley. When the bottom high-pressure flushing device 4 is rotated to be perpendicular to the tunneling direction, the entire bottom segment of the trolley 3 is flushed by the longitudinal sliding device 2. During the flushing process, the angle of the high-pressure nozzle 401 and the longitudinal movement direction are adjusted to achieve a better flushing effect.

[0032] During use, a high-pressure flushing system of the appropriate model is manufactured according to the tunnel boring machine model and the inner diameter of the tunnel segments. The circumferential high-pressure flushing device 1 and the bottom high-pressure flushing device 4 can be connected to the high-pressure pipeline on the trolley 3 via high-pressure hoses.

By controlling the drive motor 201 on the longitudinal sliding device 2 to drive the gear to rotate, the gear meshes with the rack fixed on the slide rail 202, thereby driving the longitudinal sliding device 2 to move and realize the longitudinal reciprocating movement of the high-pressure flushing device 1 to complete the flushing action of the tunnel segments except for the bottom passage of the trolley 3. In addition, the bottom high-pressure flushing device 4 can be rotated by rotating the second motor 405 to rotate it parallel to the tunneling direction and adjust the angle of the second high-pressure nozzle 401 to complete the flushing of the tunnel segments at the bottom of the walkway on both sides of the trolley. The bottom high-pressure flushing device is rotated to be perpendicular to the tunneling direction, and then the longitudinal sliding device 2 realizes the flushing action of the entire bottom tunnel segments of the trolley 3. During the flushing process, the angle of the second high-pressure nozzle 401 and the longitudinal movement direction are adjusted to thoroughly clean the bottom tunnel segments.
