Description

Technical Field

[0001] This utility model relates to the technical field of shield tunnel synchronous grouting and cleaning equipment, specifically a subway shield tunnel synchronous grouting and cleaning device. Background Technology

[0002] Synchronous grouting devices for subway tunnel boring machines (TBMs) are one of the commonly used pieces of equipment in subway TBM construction. During the construction process, the TBM is responsible for excavating and advancing the underground tunnel, while the synchronous grouting device is used to grout and reinforce the excavated underground tunnel to enhance the stability and waterproofing of the underground structure.

[0003] However, during the construction of subway tunnel boring machines, due to the complex underground environment, a large amount of impurities such as mud, silt, and rock debris may be generated. These impurities will adhere to the internal channels and grouting pipes of the synchronous grouting device, causing channel blockage, increased grouting resistance, and affecting the normal operation of the device and the grouting effect.

[0017] The principle and beneficial effects of this utility model are as follows:

[0018] 1. The present invention provides a synchronous grouting and cleaning device for subway shield tunnels, wherein a transmission device is adapted to one side of the cylinder, a cleaning device is fixedly installed at one end of the transmission device, a connecting device is installed on one side of the cleaning device, an auxiliary device is installed at one end of the connecting device, and a cleaning device is adapted to one end of the transmission device. When cleaning of the inner wall of the cylinder is required, the control device controls the operation of the drive motor, which drives the drive shaft to rotate. The drive shaft drives the first gear on the surface to rotate, which in turn drives the second gear to rotate. The second gear drives the threaded rod to rotate, and the threaded rod rotates according to the threads on the inner wall of the telescopic sleeve, causing the threaded rod to move back and forth. When the threaded rod moves back and forth, it drives the telescopic sleeve to extend and retract synchronously. When the threaded rod rotates, it drives the drive ring at one end to rotate, which in turn drives the cleaning rod to rotate. The cleaning rod drives the cleaning ring to rotate, allowing the cleaning ring to perform preliminary cleaning and scraping of impurities on the inner wall of the cylinder. At the same time, the rotation of the cleaning ring drives the auxiliary ring to rotate through the connecting device. The auxiliary ring drives the auxiliary rod to rotate, which in turn drives the auxiliary rotating ring to rotate according to the drive groove at one end of the telescopic sleeve. Simultaneously, the threaded rod rotates during this process. The rotating cleaning ring controls the high-pressure nozzles to perform high-pressure rinsing on the inner wall of the cylinder. The water source for the high-pressure nozzles is transmitted through water grooves opened on the inner wall of the threaded rod. After rinsing, the auxiliary ring further cleans the inner wall of the cylinder, ensuring thorough cleaning. The connecting device saves space when the device is not in use. By moving the auxiliary ring to one end of the cylinder using the threaded rod, the auxiliary ring applies pressure to the connecting rod, which transmits the pressure to the connecting column. The connecting column moves under pressure within the limiting groove, and its movement is limited by the limiting groove and the connecting retaining ring. When the connecting column moves, it applies pressure to the connecting spring, causing the spring to deform under pressure, thus saving space in the cylinder. When the device is in use, the connecting spring pushes the connecting column to move through its elastic restoring force, and the connecting column pushes the connecting rod to move, restoring the auxiliary device.

[0019] 2. This utility model provides a synchronous grouting and cleaning device for subway shield tunnels. A placement box is located below the tunnel body, and a collection device is fitted onto the inner wall of the placement box. To allow for both sealing and opening of the collection device, a sealing device is provided on one side of the tunnel body. When cleaning the inner wall of the tunnel body is required, a control device is used to operate an electric telescopic rod, causing it to extend and retract. The extension and retraction of the electric telescopic rod moves the sealing block, which in turn moves the sealing plate. The sealing plate moves according to the sealing groove and sealing slot, opening and closing the sealing plate. During cleaning, the sealing plate is in the open state, allowing the cleaned impurities to be collected in the collection box. During grouting, the sealing plate is in the closed state, sealing the tunnel body and preventing grouting material from flowing into the collection box. When the collection box needs to be replaced, a collection pull ring is used to pull the collection box out of the placement box for cleaning and replacement. When installing the collection box, the collection slots on both sides of the collection box are engaged in the placement grooves to fix the collection box and prevent it from moving.
