Abstract
The utility model relates to a conversion module for a cutter disk of a shield tunneling machine. The conversion device is arranged on the cutter disk of the tunneling machine and comprises a conversion driving mechanism and a detachable central cutting mechanism, wherein the central cutting mechanism is arranged in the center of the cutter disk and connected with spokes of the cutter disk through the conversion driving mechanism; and by adding the central cutting mechanism to the cutter disk, the cutter disk is applicable to hard rocks, and by disassembling the central cutting mechanism from the cutter disk, the cutter disk is applicable to soft rocks. Compared with the prior art, the conversion module has the advantages of convenience for use, wide application range and the like.
Description
Technical field
The utility model relates to a kind of tunnelling device, especially relates to a kind of movable conversion equipment of shield excavation machine cutterhead.
Background technology
Shield excavation machine is a kind of special engineering machinery of tunnel piercing.Its advantage is the pipeline constructing tunnel that is suitable for the big degree of depth, long distance, various diameters, and can adapt to the excavation on various soft or hards stratum.The shield excavation machine cutter-head mechanism is the core of shield excavation machine.Project practices at home and abroad shows, the shield structure can run into layer variously in construction, from mud, clay, layer of sand to soft rock and hard rock etc.As one of shield excavation machine core component, cutterhead mainly plays the excavation soil body, steady operation face and stirs the function of native sand, therefore cutterhead work under bad environment in tunneling process, stressed complicacy.Shield excavation machine cutterhead pattern and structural relation are to excavation efficient, application life and the cutter expense of shield structure, and its cutterhead configuration and type selecting mainly depend on engineering geology and hydrogeological conditions.The selection of shield excavation machine cutterhead pattern depends on its excavation stratum soil property condition.
Shield excavation machine excavation stratum generally is made up of multiple soil property, and the stratum soil property situation of its excavation need be selected suitable cutterhead pattern.Increase number of cutters under many circumstances and change tool specification and perhaps reduce the suitable excavation of the cutterhead pattern soil property that fltting speed can not guarantee its selection.Therefore need the movable conversion equipment of design cutterhead, make cutterhead at the cutting weak soil to hard rock geology or knife cutting hard rock to the smooth rapid construction of weak soil geology.
The utility model content
The purpose of the utility model is exactly the conversion equipment that a kind of easy to use, shield excavation machine cutterhead that accommodation is extensive is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of the utility model can realize through following technical scheme:
A kind of conversion equipment of shield excavation machine cutterhead; This conversion equipment is arranged on the cutterhead of development machine; Comprise conversion driving mechanism and dismountable central cutting mechanism, this central cutting mechanism is located at the center of cutterhead, is connected with the spoke of cutterhead through conversion driving mechanism; Described cutterhead constitutes the cutterhead that is applicable to hard rock after the said central cutting of installation mechanism, after the said central cutting of dismounting mechanism, constitute the cutterhead that is applicable to soft rock.
Described conversion driving mechanism comprises two clamping cylinders and two power transmission voussoirs; Described two clamping cylinders are built in the upper and lower of cutterhead spoke respectively; Described two power transmission voussoirs connect two clamping cylinders respectively, and the upper and lower of fixed center cutting mechanism.
Described clamping cylinder is connected with the bolt that passes through of power transmission voussoir.
The stationary plane of described central cutting mechanism and power transmission voussoir is provided with the inclination angle.
Described clamping cylinder is provided with tubing interface valve piece.
Compared with prior art; The utility model can be changed the cutterhead of shield excavation machine, makes it under different geological conditionss, make things convenient for shield excavation machine cutterhead driving, both can guarantee Tool in Cutting hard rock soil property function; Also can be when weak soil, cobble soil property; Reduce the cutter loss, increase casting efficient, reduce the shield cutter loss, it is easy to use, and accommodation is extensive.
Description of drawings
Fig. 1 is the overall structure sketch map that the development machine of the utility model is installed;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the detailed maps of the utility model the first half conversion driving mechanism;
Among the figure, 1 is development machine, and 2 is cutterhead, and 3 is central cutting mechanism, and 4 are the power transmission voussoir, and 5 is clamping cylinder, and 6 is bolt, and 7 is People's Bank of China's lock, and 8 is tubing interface valve piece.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1; A kind of conversion equipment of shield excavation machine cutterhead; Comprise the conversion driving mechanism that is made up of two groups of clamping cylinders 5 and power transmission voussoir 4 and dismountable central cutting mechanism 3, this central cutting mechanism 3 is located at the center of cutterhead 2, is connected with the spoke of cutterhead 2 through conversion driving mechanism; Its concrete syndeton as shown in Figures 2 and 3; Two clamp the upper and lower that oily 5 cylinders are built in cutterhead 2 spokes respectively, and two power transmission voussoirs 4 connect two clamping cylinders 5 through bolt 6 respectively, then from both direction fixed center cutting mechanism 3 up and down.Central cutting mechanism 3 is provided with the inclination angle with the stationary plane of power transmission voussoir 4, can make things convenient for the dismounting of central cutting mechanism 3.Clamping cylinder 5 is provided with tubing interface valve piece 8, through the oil pipe of these tubing interface valve piece 8 connection fuellers, and the action of control clamping cylinder.
The cutterhead 2 of development machine becomes the cutterhead that is applicable to hard rock after central cutting mechanism is installed, after removing central cutting mechanism, become the cutterhead that is applicable to soft rock.
The utility model in use; In the process of initial driving, clamping cylinder 5 is installed in cutterhead 2 spokes earlier, power transmission voussoir 4 is connected fixing with clamping cylinder 5 usefulness bolts 6; Centre of location cutting mechanism 3 is in the centre position of cutterhead 2 then; Clamping cylinder 5 promotes power transmission voussoir 4 fixed center cutting mechanisms 3, and shield excavation machine 1 driving determines whether to take out central cutting mechanism 3 through behind the soil stabilization district according to the soil property situation.If run into soft rock, then take out central cutting mechanism 3, its taking-up process is following; Clamping cylinder 5 retract cylinder drag power transmission voussoir 4; The spoke of withdrawal cutterhead 2 is inner, takes off central cutting mechanism 3 and is fetched into shield excavation machine 1 outside through People's Bank of China's lock 7, continues construction and excavation weak soil layer and gets final product.Shield excavation machine runs into hard rock; Then the mounting center cutting mechanism 3; Its installation process is following, and central cutting mechanism 3 is transported to cutterhead 2 positions through People's Bank of China's lock 7, and back, location clamping cylinder 5 promotes power transmission voussoir 4 fixed center cutting mechanisms 3 continuation construction and excavation hard formations and gets final product.
