[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] According to the embodiment of the present invention, the auxiliary device for disassembly in a mud shield tunnel comprises a trolley body 1, a hoisting mechanism and an intercepting member 6. The trolley body 1 is used to carry and move materials. The hoisting mechanism comprises a column 2 and a crossbeam 3. The column 2 is located on a first side of the trolley body 1 and is pivotally connected to the trolley body 1. The crossbeam 3 is connected to an end of the column 2 away from the trolley body 1. A single rail vehicle 4 is arranged on the crossbeam 3. An electric hoist is arranged below the single rail vehicle 4 to hoist materials. The intercepting member 6 is arranged on the second side of the trolley body 1 to prevent the movement of materials on the trolley body 1. The trolley body 1 is a battery-powered transport trolley, which uses an electric drive to drive the entire device to move. The hoisting mechanism is arranged on the trolley body 1 to assist in disassembling equipment such as mud pipes in the tunnel, without repeatedly selecting a hoisting point and hanging a manual hoist, thereby reducing construction time. The intercepting member 6 is used to block the movement of materials to prevent them from leaving the trolley body 1, thereby improving safety.

[0028] The auxiliary device for disassembly in a slurry shield tunnel according to the embodiment of the present invention has the advantages of good safety, convenient disassembly and high efficiency.

[0029] In some embodiments, the lifting mechanism further includes a rotating seat, and the two rotating seats are respectively located at the first end and the second end of the cart body 1, and the rotating seats correspond to the columns 2 one by one and are pivotally connected.

[0030] Specifically, the rotating seats are arranged at both ends of the cart body 1 to enable the columns 2 and the crossbeams 3 to rotate relative to the cart body 1, thereby achieving more flexible hanging position adjustment and facilitating manual rotation and placement of mud pipes, tracks, etc.

[0031] In some embodiments, the rotating seat includes a vertical tube and a bearing. The vertical tube is connected to the cart body 1 . The vertical tube is connected to the column 2 through a bearing. The vertical tube is perpendicular to the cart body 1 .

[0032] Specifically, the vertical pipe can be a steel pipe with a length of about 2.1 meters and a diameter of 300 mm. Such arrangement of the vertical pipe can ensure the stability of the rotating seat. The column 2 can be a steel pipe with a length of about 2.7 meters and a diameter of 200 mm. The column is sleeved in the vertical pipe and protrudes 0.6 m from the vertical pipe. Two bearings can be arranged at both ends of the vertical pipe to enhance the stability of the column.

[0033] In some embodiments, a limit baffle is provided at one end of the cross beam 3 away from the column 2 , and the limit baffle is used to block the single track vehicle 4 .

[0034] Specifically, the limit baffle is used to prevent the single-track vehicle 4 from detaching from the cross beam 3, and to prevent the single-track vehicle from sliding off the track from the front end of the cross beam 3 due to the heavy objects being hoisted. The limit baffle can be a steel plate with a size of 100mm*100mm.

[0035] In some embodiments, the lifting mechanism further includes an oblique support, which is located between and connected to the cross beam 3 and the column 2 .

[0036] Specifically, a triangular structure is formed between the oblique support, the cross beam 3 and the column 2, which improves the structural strength between the cross beam 3 and the column 2, increases the stability of the hoisting mechanism, and strengthens the bearing capacity of the cross beam 3. Optionally, there are two oblique supports to further increase the bearing capacity.

[0037] In some embodiments, the angle between the inclined support and the column 2 is 45°.

[0038] Specifically, when the angle between the oblique support and the column 2 is 45°, the supporting effect on the crossbeam 3 is optimal.

[0039] In some embodiments, the intercepting member 6 includes a protective tube, and the two protective tubes are respectively located at the first end and the second end of the cart body 1 , and the protective tubes are arranged on both sides of the cart body 1 corresponding to the columns 2 .

[0040] Specifically, the protective tube and the column 2 are respectively arranged on both sides of the pallet body 1. The protective tube can effectively prevent the material from moving and ensure the safety of the operation. The protective tube can be a square tube, and the height of the protective tube is related to the height of the piled material on the pallet body 1.

[0041] In some embodiments, the protection tube is rotatably connected to the cart body 1 , and the protection tube has a first position that fits the top of the cart body 1 and a second position that is perpendicular to the cart body 1 , and the protection tube can rotate between the first position and the second position.

[0042] Specifically, the protective tube is rotatably connected to the cart body 1. When not in use, the protective tube can be folded up to facilitate personnel to carry equipment up and down. When the protective tube is rotated to the second position, it can prevent materials from rolling to ensure safety. The protective tube can be connected to the cart body 1 through a hinge.

[0043] In some embodiments, the slurry shield tunnel disassembly auxiliary device also includes a safety net, the two ends of the safety net are respectively connected to the two columns 2, and the safety net is used to support the fallen materials.

[0044] Specifically, the safety net is arranged under the crossbeam 3 to support the falling materials, avoid injuring the workers, and ensure the safety of the workers during the lifting operation.

[0045] In some embodiments, the slurry shield tunnel in-tunnel disassembly auxiliary device further includes a stabilizing bracket, which is located on both sides of the cart body 1 and is telescopically connected to the cart body 1 to support the cart body 1.

[0046] Specifically, the stabilizing brackets arranged on both sides of the cart body 1 can abut against the inner wall of the slurry shield tunnel to support the cart body 1, thereby preventing the overall center of the equipment from shifting during lifting and causing the cart to tilt or even overturn.

[0047] According to the method for disassembling a slurry pipe in a slurry shield tunnel according to an embodiment of the present invention, the method for disassembling a slurry pipe in a slurry shield tunnel comprises the following steps:

[0048] The pallet truck body is moved to the working position, and the connecting crossbeam of the rotating hoisting mechanism on the pallet truck body and the column of the pallet truck body are rotated until the crossbeam is adjacent to the target mud pipe;

[0049] Remove the screws of the target mud pipe and wrap the chain of the electric hoist under the single track vehicle on the beam;

[0050] Cut the remaining screws of the target mud pipe and control the electric hoist to lift the target mud pipe;

[0051] Rotate the upright column and hang the target mud pipe onto the vehicle body;

[0052] Repeat the above steps to remove other mud pipes until the cart body reaches the upper limit of the number of mud pipes that can be stored;

[0053] The mobile trolley body is separated from the slurry shield tunnel and the slurry pipe on the trolley body is hoisted and unloaded to the ground.

[0054] Specifically, the cart body moves in the slurry shield hole, i.e., the slurry shield tunnel, to dismantle the supporting auxiliary facilities such as the mud pipeline, water pipe, and rails, which is convenient for subsequent construction. The rotation of the column of the lifting mechanism drives the crossbeam to move closer to the target mud pipe to facilitate the subsequent lifting operation. Two personnel can be assigned to remove the screws of the target mud pipe, and two personnel can be assigned to wrap the electric hoist chain to complete the preparation work for the lifting operation. One person is assigned to cut the remaining screws on the mud pipe to improve the disassembly efficiency. Rotating the column can reduce the lifting time of the target mud pipe and improve efficiency. The target mud pipe can be placed on the cart body for temporary storage. Repeat the above four steps to dismantle the mud pipe until the number of mud pipes on the cart body reaches the upper limit of the storage number. Move the cart body to drive the mud pipe out of the tunnel, lift and unload the mud pipe on the cart body to the ground, and move the cart body back into the tunnel to continue the operation.
