Description

Technical Field

[0001] The utility model relates to the technical field of TBM construction, in particular to a TBM dismantling system for a large-angle inclined shaft. Background Art

[0002] The existing dismantling scheme for TBM underground chambers in steeply inclined shafts generally utilizes the turning function of the TBM, turns through the steep slope section within the established route plan, and then sets up a lifting beam in the chamber after turning into a horizontal section for dismantling construction. The turning capacity of the TBM is restricted by current technological development. The turning radius of the TBM equipment cannot be combined with the turning radius of the inclined shaft. Improving the turning capacity of the TBM will greatly increase the equipment cost, and not improving the turning capacity will increase the project cost. In addition, due to the large excavation of the dismantling chamber and the low overlap of the anti-arc section, manual secondary excavation and concrete backfilling are required after the construction of the TBM equipment is completed, which restricts the progress of the project; at the same time, the traditional dismantling method requires the equipment to be disassembled into smaller parts, which also greatly affects the efficiency of the TBM equipment transfer, assembly and commissioning. Therefore, the current traditional TBM dismantling method greatly affects the project cost and construction period. Utility Model Content

[0067] Embodiment 2:

[0068] After the TBM is excavated, spray-mixed support is required to reduce the hole diameter, which makes it impossible for the cutterhead to be dismantled by returning to the original route. Therefore, the dismantling device of the TBM in the high-angle inclined shaft adopts the method of cutterhead dismantling and main machine dismantling. The dismantling principles are introduced below:

[0069] (1) The cutter head disassembly process consists of three main steps: cutter head separation, cutter head angle adjustment, and cutter head transportation:

[0070] The main steps of cutting disc separation are: When the TBM equipment 5 is disassembled, the TBM equipment 5 is located at the lower end of the inclined shaft 4. First, the second push rod device 203 and the third push rod device 206 work together to adjust the angles of the receiving main beam 209 and the receiving plate 210, so that the receiving plate 210 is close to the bottom of the cutting disc and the angle is aligned, such as Fig.12As shown, the cutter disc is then fixed to the receiving plate 210 by welding, bolting, or bundling, and finally the connection between the cutter disc and the main machine is released, and the rock surface is tightened by the support boots provided by the main machine of the TBM equipment, and the cutter disc is separated.

[0071] The main steps of adjusting the cutter head angle are: adjusting the angles of the receiving main beam 209 and the receiving plate 210 by the cooperation of the second push rod device 203 and the third push rod device 206, so that the receiving plate 210 is parallel to the ground, such as Fig.13 As shown, the lifting device 212 is then adjusted so that the caster 211 directly bears the load of the receiving plate 210 and the cutter disc, thereby completing the cutter disc angle adjustment;

[0072] The main steps of transporting the cutter disc are: removing the bolt connection between the receiving plate 210 and the receiving main beam 209, continuing to adjust the lifting device 212, the second push rod device 203 and the third push rod device 206 to separate the receiving plate 210 from the receiving main beam 209, and then using the casters 211 to transport the receiving plate 210 and the cutter disc out of the passage between the fixed columns 202 along the lower flat hole, as shown in FIG. Fig.17 As shown, the cutter head disassembly is completed.

[0073] (2) The disassembly of the main engine is divided into three main steps: pulling back the main engine, adjusting the angle of the main engine, and lifting and shipping:

[0074] The main steps of pulling the main machine back are: after completing the cutterhead separation step, use the TBM main machine's own support shoes to hold the rock surface tightly and then step back to the track of inclined shaft excavation. Fig.13 As shown, the wheels are then installed on the TBM mainframe by welding or bolting, and then the gripper is loosened, and the mainframe is pulled to the expansion area 112 at the top of the inclined shaft by the power winch 101, the steering pulley 102 and the steel cable 103, as shown in FIG. Fig.14 shown.

[0075] The main steps of adjusting the angle of the main engine are: adjusting the angle of the movable push plate 110 through the first push rod device 111, adjusting the position of the steering pulley 102 through the pulley power box 107 and the lifting mechanism 108, and controlling the length of the steel cable 103 through the power winch 101, so as to coordinately adjust the main engine to a vertical state, such as Fig.15 As shown, the host angle adjustment is completed.

[0076] The main steps of the main engine hoisting and shipping are: through the pulley power box 107, the lifting mechanism 108 and the power winch 101, the main engine is lifted to the upper flat hole or industrial square of the inclined shaft 4, such as Fig.16 , 17 As shown in the figure, after loading, the steel cable is released and the main machine is transported out by vehicle.
