Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device for disassembling a shield machine in a tunnel. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. The shield construction method is that the tunnel boring machine builds (lays) the "shield" (referring to the supporting segments) of the tunnel while excavating, which is different from the open construction method. Internationally, the broad shield machine can also be used in rock formations, but it is different from the open (non-shield method) tunnel boring machine. In my country, tunnel boring machines used in soft soil formations are usually called (narrow sense) shield machines. During the disassembly process of the shield machine, a hoisting device is usually required to transport the disassembled equipment.

[0003] For example, a Chinese authorized patent with announcement number CN218708782U is a shield machine in-tunnel disassembly system, which includes a shield machine shield shell, equipment to be dismantled, a battery car and a main pipe piece car. A plurality of first lifting ears are welded to the upper part of the inner part of the shield machine shield shell, and a hand chain hoist is connected to the first lifting ear. The equipment to be dismantled is provided with a plurality of second lifting ears, and the other end of the hand chain hoist is connected to the second lifting ear. The main pipe piece car is located at a position opposite to the equipment to be dismantled, and a portal frame is fixedly installed on the main pipe piece car, and the battery car drives the main pipe piece car to move. The utility model provides a shield machine in-tunnel disassembly system, which solves the problem that the internal space of the shield machine is small and most of the equipment is large in size or heavy, and it is impossible to rely on large-scale lifting equipment, resulting in great difficulties in lifting and transportation during dismantling.

[0004] The above-mentioned traditional lifting device is complicated to operate during transportation, and workers are required to operate at different height planes during transportation, which affects the use effect of the equipment. In addition, the lifting and transportation process is time-consuming and labor-intensive, reducing the transportation efficiency of the equipment. Utility Model Content

[0030] Example

[0031] Reference Figure 1-7As shown, a hoisting device for disassembly in a shield machine tunnel comprises a shield shell 1 of the shield machine, and also comprises a movable plate 211 which can be moved laterally, a support plate 215 which is distributed in parallel above the movable plate 211 and is used to support the disassembled materials, a connecting column 214 which is used to fix the movable plate 211 and the support plate 215, a hydraulic rod 217 installed on the inner wall of the top end of the shield shell 1 of the shield machine, a first connecting piece 218 which is connected to the output end of the hydraulic rod 217, a second connecting piece 219 which is detachably connected to the outer wall of the movable plate 211, and an articulated rod 220 which is rotatably connected to the first connecting piece 218 and the second connecting piece 219, wherein the hydraulic rod 217 is opened to drive the first connecting piece 218 to be pressed downward, thereby pushing the articulated rod 220 from an inclined state to a horizontal state, pushing the second connecting piece 219 and the movable plate 211 to move laterally, and realizing the purpose of hoisting and discharging materials. Four groups of moving wheels 212 are installed at the bottom of the moving plate 211. A moving track 213 matching the moving wheels 212 is provided on the inner wall at the bottom of the shield shell 1 of the shield machine. The moving wheels 212 and the moving track 213 can facilitate the horizontal reciprocating movement of the moving plate 211, making the discharging effect more time-saving and labor-saving. A fixed plate 223 is fixed on the outer wall of the moving plate 211. A groove 224 is provided inside the fixed plate 223. A threaded rod 225 passing through the groove 224 is fixed at the bottom of the second connecting member 219. The hinge rod 220 is rotated and the threaded rod 225 at the bottom of the second connecting member 219 is driven to be inserted into the groove 224, which can achieve a better connection effect. The groove 224 is waist-shaped, and the length of the groove 224 is greater than twice the diameter length of the threaded rod 225, which ensures that the threaded rod 225 can enter and exit the groove 224 through the rotation of the second connecting member 219 without being restricted, thereby ensuring the stability of the connection. The outer wall of the threaded rod 225 is threadedly connected with a nut 227, and the outer wall of the threaded rod 225 is sleeved with a gasket 226. The fixing plate 223 and the nut 227 are connected via the gasket 226. The gasket 226 can provide good stability. The rotating nut 227 can be connected and fixed to the threaded rod 225 under the action of the thread, further ensuring the stability of the connection between the second connecting member 219 and the fixing plate 223.

[0032] A first magnetic block 221 is fixed to the top of the articulated rod 220, and a second magnetic block 222 corresponding to the first magnetic block 221 is fixed to the inner wall of the top of the shield shell 1 of the shield machine. The first magnetic block 221 and the second magnetic block 222 are adsorbed and connected. The first magnetic block 221 and the second magnetic block can be mutually adsorbed magnet structures, which can fix the articulated rod 220. When lifting operations are not required, the occupied area inside the equipment can be reduced, thereby achieving efficient use effects.

[0033] The outer wall of the support plate 215 is fixed with a sliding block 312, and the outer wall of the support plate 215 is sleeved with a protective sleeve 216. The protective sleeve 216 has a sliding groove 311 inside that slides with the sliding block 312. The protective sleeve 216 can move up and down through the sliding groove 311 and the sliding block 312. The material is placed on the support plate 215 for support and moves with the movement of the moving plate 211. The protective sleeve 216 can protect the material to prevent it from falling off during transportation. The outer wall of the protective sleeve 216 is fixed with a bracket 313, and the bracket 313 is penetrated by a plug rod 314. The outer wall of the sliding block 312 is provided with a slot 315 corresponding to the plug rod 314. After the protective sleeve 216 is raised, the position of the protective sleeve 216 can be locked by inserting the plug rod 314 into the slot 315 to ensure that the protective sleeve 216 will not fall off. A baffle 316 is fixed to one end of the insertion rod 314 away from the sliding block 312, and a spring 317 is wrapped around the outer wall of the insertion rod 314. One end of the spring 317 is connected to the baffle 316 and the other end is connected to the bracket 313. The provision of the spring 317 can provide further stability. In the initial state, the spring 317 is in an extended state, which can push the insertion rod 314 to be inserted into the slot 315, ensuring that the insertion rod 314 will not fall off, thereby enhancing the use effect of the device.

[0034] Working principle: When it is needed, the material to be disassembled is placed on the support plate 215, and then the protective cover 216 is pulled upward to make the sliding block 312 slide along the inner wall of the sliding groove 311, so that the insertion rod 314 corresponds to the slot 315, and then the baffle 316 is released, and the insertion rod 314 is driven to be inserted into the slot 315 under the elasticity of the spring 317, which can be used to limit the protective cover 216 from falling off. At the same time, the protective cover 216 can protect the material to prevent the material from falling off.

[0035] By pulling the hinged rod 220 downward and disengaging the first magnetic block 221 from the second magnetic block 222, the threaded rod 225 at the bottom of the second connecting member 219 can be inserted into the groove 224, and then the gasket 226 is sleeved on the threaded rod 225 and fits with the fixed plate 223, and the nut 227 is rotated to make it threadedly connected with the threaded rod 225, so that the second connecting member 219 can be locked, and the first connecting member 218 is driven downward by opening the hydraulic rod 217, and the hinged rod 220 is pushed to rotate to a horizontal state, driving the movable plate 211 to move to the right under the action of the movable wheel 212 and the movable track 213, thereby achieving the purpose of lifting and transportation.
