[0018] Each group of telescopic parts includes a drive frame 5, a drive tube 17, two groups of auxiliary parts and a first hydraulic motor 6. The two drive frames 5 are respectively detachably connected to the first telescopic tube sleeve 15 and the second telescopic tube sleeve 16 and are located on the outside of the drive tube 17. The two drive tubes 17 are respectively detachably connected to the first telescopic tube sleeve 15 and the second telescopic tube sleeve 16 and are located on the outside of the first telescopic tube sleeve 15 and the second telescopic tube sleeve 16. The two groups of auxiliary parts are symmetrically arranged. The auxiliary parts are slidably connected to the bracket 3 and are located between the two rack guide rails 4. The first hydraulic motor 6 is engaged with the rack guide rail 4 and is located on the outside of the drive frame 5.

[0019] In this embodiment, the first telescopic tube sleeve 15 and the second telescopic tube sleeve 16 are respectively installed in the bracket 3 at the rear end of the first pipeline 1 and the second pipeline 2. The first telescopic tube sleeve 15 and the second telescopic tube sleeve 16 are specially made telescopic tube sleeves with wear resistance and explosion-proof performance. They can maintain sealing under high pressure and high flow working environment. The extended part of the telescopic sleeve is more than 2 times longer than the tunnel mud. The first ends of the first pipeline 1 and the second pipeline 2 are connected to each other, and the ends of the first pipeline 1 and the second pipeline 2 connected to the trolley pipeline are fixed to the bracket. 3, the ends of the first pipeline 1 and the second pipeline 2 connected to the tunnel pipeline are respectively fixed on the corresponding drive frame 5, and the sides of the first pipeline 1 and the second pipeline 2 connected to the trolley pipeline are connected to the tunnel pipeline through the first telescopic pipe sleeve 15, the second telescopic pipe sleeve 16 and the drive pipe 17, and the connections between the pipelines are all detachable using bolts.

The first hydraulic drive motor 6 connected to the first telescopic pipe sleeve 15 is engaged with the rack guide 4 through the gear, so that the driving frame 5 drives the first telescopic pipe sleeve 15 to extend and retract in the bracket 3. The auxiliary part assists the driving frame 5 to move, and the mud pipe of the first telescopic pipe sleeve 15 is lifted out, and the mud pipe on the pipe storage device is lifted to the pipe replacement area in conjunction with the pipe replacement crane, and then the first telescopic pipe sleeve 15 is lifted out.

The extension operation of the second telescopic sleeve 16 is the same as that of the first telescopic sleeve 15, but the extension direction of the second telescopic sleeve 16 is opposite to that of the first telescopic sleeve 15, so as to achieve non-interference between the equipment. This can effectively solve the problem that the mud and water pipeline needs to be replaced after the shield tunneling has advanced a certain distance, resulting in the inability to carry out continuous tunneling operations.

[0020] Furthermore, each group of the telescopic parts also includes a pressure sensor 7 and a first hydraulic ball valve 8. The pressure sensor 7 is fixedly connected to the drive tube 17 and is located above the drive tube 17. The first hydraulic ball valve 8 is fixedly connected to the drive tube 17 and is located below the drive tube 17.

[0021] In this embodiment, after closing the first pipeline 1, the drive pipe 17 is opened through the first hydraulic ball valve 8, thereby releasing the internal pressure of the first telescopic pipe sleeve 15 and discharging the slurry remaining in the pipe into a preset slag collecting tank. The pressure sensor 7 monitors the internal pressure of the drive pipe 17.

[0022] Furthermore, the auxiliary parts include two walking wheels 9 and four deflection wheels 10, the two walking wheels 9 are slidingly connected to the bracket 3 and are located on the outside of the driving frame 5, and the two deflection wheels 10 are fixedly connected to the driving frame 5 and are located on the outside of the walking wheels 9.

[0023] In this embodiment, the running wheels 9 assist the movement of the driving frame 5 , and the deflection-blocking wheels 10 prevent the driving frame 5 from deflecting during movement.

[0024] Furthermore, the auxiliary component also includes a second hydraulic motor 11 and a driving gear 14 . The second hydraulic motor 11 is arranged at the center of the driving frame 5 . The driving gear 14 is engaged with the rack guide 4 and is located outside the second hydraulic motor 11 .

[0025] In this embodiment, the second hydraulic motor 11 is controlled by the control system through the solenoid valve block, and the driving gear 14 is provided at the output end.

[0026] Furthermore, the mud and water pipeline extension device also includes a second hydraulic ball valve 12 and a flow meter 13 . The second hydraulic ball valve 12 is arranged in the first pipeline 1 . The flow meter 13 is fixedly connected to the first pipeline 1 and is located outside the second hydraulic ball valve 12 .

[0027] In this embodiment, after the first pipeline 1 extends the distance of a mud pipe section, the second hydraulic ball valve 12 on the first pipeline 1 is closed, thereby cutting off the first pipeline 1, and the second hydraulic ball valve 12 on the second pipeline 2 is opened, so that the second pipeline 2 is put into use, and the flow meter 13 cooperates with the pressure sensor 7 to determine and monitor the pressure and measurement of the pipeline.

[0028] The beneficial effects of the present invention are as follows: the first telescopic pipe sleeve 15 and the second telescopic pipe sleeve 16 are respectively installed in the bracket 3 at the rear ends of the first pipeline 1 and the second pipeline 2. After the first telescopic pipe sleeve 15 of the first pipeline 1 extends a distance of a mud pipe section, the control system issues an alarm, the second hydraulic ball valve 12 on the first pipeline 1 is closed, the first pipeline 1 is cut off, the second hydraulic ball valve 12 on the second pipeline 2 is opened, and the second pipeline 2 is put into use. After the pipeline switching is completed, the control system issues a warning prompt and opens the drive pipe 17 through the first hydraulic ball valve 8, thereby releasing the first telescopic pipe sleeve 15. The first telescopic pipe sleeve 15 is connected to the first hydraulic drive motor 6 of the first telescopic pipe sleeve 15, and the first hydraulic ball valve 8 of the first telescopic pipe sleeve 15 is closed after the set time. After the system analyzes and determines that it is safe through the flow meter 13 and the pressure sensor 7, the alarm is automatically released, and the operator can disconnect the first telescopic pipe sleeve 15 from the tunnel pipeline. The operator switches the remote control to control the driving frame 5 of the first pipeline 1 to move. The first hydraulic drive motor 6 connected to the first telescopic pipe sleeve 15 is engaged with the rack guide 4 through the gear, so that the driving frame 5 drives the first telescopic pipe sleeve 15 to move in the bracket 3. The second hydraulic drive motor 11 is engaged with the rack guide 4 through the driving gear 14, the walking wheel 9 assists the movement of the driving frame 5, and the deflection wheel 10 prevents the driving frame 5 from deflecting when moving, and assists the driving frame 5 to drive the first telescopic pipe sleeve 15 to extend and retract, thereby realizing the forward and backward movement of the driving frame 5, and cooperates with the pipe changing crane to lift out the mud pipe of the first telescopic pipe sleeve 15, and uses the pipe changing crane to lift the mud pipe on the pipe storage device to the pipe changing area, and then connects the first telescopic pipe sleeve 15 to the pipeline in the tunnel and the first pipeline 1 and locks it. During this process, the control system of the device is kept connected with the shield machine control system. The whole process is monitored to ensure that no leakage or other unexpected situations occur during the disconnection process. After the second telescopic pipe sleeve 16 of the second pipeline 2 is extended by the distance of two sections of the mud pipe, it is automatically switched to the first pipeline 1 for operation, and an alarm is issued to remind the operator to extend the pipeline. The extension operation of the second telescopic pipe sleeve 16 of the second pipeline 2 is the same as the extension operation of the first pipeline 1. Then the second telescopic pipe sleeve 16 is hoisted and replaced, and then connected to the second pipeline 2 and the pipeline in the tunnel and locked. This process can be completed in a short time, thereby making the cement pipeline extension and replacement process faster and more efficient, reducing manpower and time investment, and further reducing production costs.
