The utility model has the advantages of service life enhancement of the shield machine, easy management of soil pressure, weight lightening, welding technology introduction, easy chemical consolidation of the excavation face, load bearing capacity increase, good fluidity of the sand in a soil bin chamber, cost reduction and construction progress enhancement.
Description
[technical field] the utility model relates to a kind of cutter head of shield machine arch support, belongs to the core component that underground engineering construction machinery is shield machine, is mainly used in mechanized constructions such as subway, diversion works, subterranean tunnel construction.
[background technology] cutter head of shield machine braced structures is the main core component of shield machine, and its quality directly influences shield machine application life, and then influences the engineering construction progress.
Usually the cutterhead braced structures form that adopts in the world has three kinds of structures at present, and as shown in Figure 1, wherein Figure 1A is that the axis of centres supports; Figure 1B is an intermediate supports; Fig. 1 C is a peripheral support, above-mentioned three kinds of form of structure all in various degree exist deficiency.A structure cutterhead soil bin is wide, native sand good fluidity, and soil pressuring management is easy, but Heavy Weight, assembly difficulty is big, and the excavation surface chemistry is reinforced difficulty, and the withstand load of bearing is than B, C little (enabling capabilities is little); The space is narrow in the B structure middle girder, narrow space in the native bin, and native sand flowability is bad in this space, and the excavation surface chemistry is reinforced difficulty; Soil in the C-structure soil bin is mobile bad, native sand takes place easily adhere to, and soil pressuring management is difficulty relatively.
[summary of the invention] the purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of cutter head of shield machine to support, this braced structures has alleviated shield machine weight, reduced cost of manufacture, be convenient to soil pressuring management in the native bin, and shield machine application life and operating efficiency have been improved, increase supporting capacity, and then shortened the construction period.
The purpose of this utility model realizes by following technological means.
A kind of cutter head of shield machine arch support comprises the cutterhead that is installed on the axis of centres, it is characterized in that on the said axis of centres arch support being installed, and is equipped with the gear wheel spring bearing in this support; The cutterhead rotating driving device connects the cutter plate driver pinion; Gear wheel is meshed with the cutter plate driver pinion.
The above-mentioned axis of centres comprises circle, square, triangle arbitrary shape.The bracing frame of arch support and supporting disk can adopt split-type structural, and adopt welding, bolt or flange to connect; Perhaps adopt integral structure.Cutterhead and the axis of centres can adopt welding or bolt, spline, flange to be connected.Equally, the connection between the axis of centres and the bracing frame also can be adopted welding, bolt, flange.
Its operating principle is that the cutterhead driving device driving pinion rotates, and drives gear wheel and then drive the axis of centres, arch support and cutterhead together to rotate, and cuts native sand by the cutting force that is installed in cutter head on the cutterhead and central part cutter head and begins driving.
The more existing braced structures of this cutter head of shield machine arch support has many advantages, be that aspects such as bearing load, assembly technology, native sand flowability all demonstrate and show unique characteristics, it is low to have solved the bearing load that exists during cutter head of shield machine supports for many years, problems such as complex process.After this cutter head of shield machine is supported on the above-mentioned three kinds of form of structure of abundant analysis, having designed and developed novel cutterhead braced structures is the arch support structure, has overcome the deficiency that above-mentioned three kinds of form of structure exist, and shield machine is improved application life greatly, soil pressuring management is easy, alleviated weight, introduced welding procedure, the excavation surface chemistry has been reinforced be more prone to, increased supporting capacity, can make simultaneously the native sand in the native bin mobile better, reduce cost, improve construction speed.
This cutter head of shield machine arch support structure as can be seen from Figure 2 has native bin broadness, native sand good fluidity, and soil pressuring management is easy, and the excavation surface chemistry is reinforced characteristics such as easy.Because adopt three row, three wheel bearings, supporting capacity is big, the cutterhead arch support adopts general structural steel, and welding is easy, and assembling is simple, and does not seal near the welding position, does not therefore have the heat affecting of sealing; Easier in the manufacturing than spline interconnection system, be convenient to the cutterhead maintenance.
The advantage of cutter head of shield machine arch support provided by the utility model and effect:
Advantage: the novel braced structures of the described cutterhead of this patent, it is moving that the interior broadness of soil bin is convenient to native sand flow, soil pressuring management is easy, and assembly technology is simple, and cutterhead is disassembled easily, be convenient to the cutterhead maintenance, the excavation surface chemistry is reinforced easily, and supporting capacity is big, owing to adopt general structural steel, good welding performance, weight reduction.
Effect: (1) has improved shield machine application life; (2) improved operating efficiency greatly.
[description of drawings] Figure 1A, B, C are that cutterhead supports existing three kinds of structural representations.
Fig. 2 is the utility model embodiment of institute cutter head of shield machine braced structures schematic diagram.
Fig. 3 is that Fig. 2 A-A is to structural representation.
