Description

Cutter transfer system of slurry shield machine

Technical Field

The utility model relates to a shield constructs construction technical field, concretely relates to muddy water shield constructs machine cutter transit system.

Background

With the development of science and technology and the continuous improvement of urbanization level, tunnel construction is gradually developing towards the direction of large burial depth and large diameter. The major diameter tunnel is mostly a long distance and the hardness is uneven composite stratum, the tunneling of the stratum puts higher requirements on the service life of the shield machine cutter, so the repair or replacement of the cutter is inevitable in the tunneling process. Therefore, frequent shutdown and cabin opening for maintenance or cutter replacement in the shield tunnel construction process becomes a normal state. The conventional tool changing technology can be divided into a normal pressure tool changing technology and an under-pressure tool changing technology according to the pressure state of the shield machine during tool changing. Due to the complexity and variability of geological conditions and the limitation of peripheral conditions, the soil body is reinforced in front of an excavation surface, so that the normal-pressure cabin entering operation is difficult to realize. The belt pressing cabin entering technology is a preferred choice for the operation of slurry shield cabin entering under the current complex geological conditions due to the characteristics of no need of stratum reinforcement, strong geological adaptability, low requirement on the surrounding environment, small influence and the like.

The pressurized tool changing technology is characterized in that on the premise of ensuring the stability of an excavation surface, an operator firstly enters a cabin, after the pressure in the cabin is the same as the pressure of an air cushion cabin, the operator enters a muddy water cabin through the air cushion cabin to carry out tool changing operation, after the operation is finished, the muddy water cabin returns to the cabin to be gradually decompressed, and finally returns to the ground normal pressure state. When the cutter, especially the hob, of the shield machine is heavy, the replacement and the transportation of the cutter are completed by combining special equipment and manual transportation. Considering that the physical strength consumption of operators in the pressurized environment is far greater than that of operators in the same operation under normal pressure, the cutter conveying path is shortened as much as possible, and the reverse conveying times are reduced.

At present, a tool changing operator generally installs and removes tools near the left side (namely, 9 o 'clock position) or the right side (namely, 3 o' clock position) of a muddy water bin, and the removed tools enter the left side or the right side of an air cushion bin through a front bin door and are transported to a specified position of the material bin. Before the cutter is disassembled and assembled, the liquid level needs to be reduced to the positions of 3 o 'clock and 9 o' clock, the process takes longer time, and the construction progress is influenced.

In order to solve the problems, the construction efficiency can be improved by adopting a mode of reducing the liquid level descending height, so that a tool changing operator needs to disassemble and assemble tools at the top of the muddy water bin (namely, at a 12 o' clock position), the disassembled tools enter the top of the air cushion bin through the front cabin door, and then the tools are transported to the left side or the right side of the air cushion bin from the top of the air cushion bin. The process of transporting to the left side or the right side of the air cushion bin from the top of the air cushion bin needs multi-level hoisting, and the multi-level hoisting needs a plurality of hoisting hoists and knife transporting crane beams, so that the transporting process of the whole knife in the air cushion bin is complex, the efficiency is low, meanwhile, the installation of the whole device is troublesome, and the manufacturing cost is high.
