Description
Technical field
The present invention relates to the realm of building construction, be mainly used in the shield machine in the constructing tunnel.
Background technology
In shield construction, whether the abrasion condition of shield machine cutter is directly connected to construction can carry out smoothly, still work long hours after the generation cutter transfinites wearing and tearing as shield machine, can cause cutter will reduce, increased the incrusted probability of cutter head of shield machine the stirring dynamics of the soil body; Can cause the shield machine fltting speed to reduce, propulsive torque was once big, had increased the working load of shield machine; Can aggravate the wearing and tearing of cutterhead, influence the serviceable life of cutterhead; Can increase the thermal value of cutter and cutterhead, influence drives the serviceable life of sealing, in a word, when still working long hours after shield machine cutter weares and teares as transfiniting, the operate as normal of shield machine will be influenced, influence normally carrying out of constructing tunnel, so when the shield machine cutter wear extent value of reaching capacity, must in time change, but because the restriction of shield machine principle of work, causing opens a position when checking the tool wear situation, have the technology very complicated, expend time in long, security is low, check the high problem of cost.
Summary of the invention
The utility model is at checking what shield machine cutter abrasion condition situation loaded down with trivial details, time-consuming, dangerous, that cost is high was invented owing to the restriction of shield machine principle of work causes in the current shield-tunneling construction.
The present invention is by protection sword (1); major cutting edge (2); cutter hub (3); plug screw (4); hydraulic pressure oil duct (5) and wearing layer (6) are formed; hydraulic pressure oil duct (5) is arranged on cutter hub (3); hydraulic pressure oil duct (5) one ends are blind end; one end is that plug screw (4) or other modes are stopped up end; one end is for connecting the oil pipe end; in the fluid pressure line that hydraulic pressure oil duct (5) reaches with the A mouth is connected, be sealed with the hydraulic oil that has pressure; pressure in the hydraulic pressure oil duct (5) can detect by the pressure detection instrument that is connected on the oil circuit on the A mouth; when tool abrasion reaches wear limit rating; the blind end point of hydraulic pressure oil duct (5) is worn through; hydraulic oil in the hydraulic pressure oil duct (5) leaks; the pressure detection instrument detects the hydraulic fluid pressure value that hydraulic pressure oil duct (5) the internal pressure value after worn out obviously descends, and shows the tool abrasion attrition value that reached capacity this moment.The tear-to-wear allowance of major cutting edge (2) (being the permission attrition value of cutter) is the vertical range of the most advanced and sophisticated place of hydraulic pressure oil duct (5) blind end apart from the most advanced and sophisticated place of major cutting edge (2), this has guaranteed that when major cutting edge (2) reaches capacity wear extent hydraulic pressure oil duct (5) blind end tip also is worn through.The blind end of the hydraulic pressure oil duct (5) on the cutter hub (3) is positioned between major cutting edge (2) and the protection sword (1), and can prevent influences the accuracy that tool abrasion detects because the wearing and tearing of cutter back cause hydraulic pressure oil duct (5) blind end tip worn out.Be installed in the pressure detection instrument that connects on the A mouth oil circuit and detect hydraulic pressure oil duct (5) internal pressure value, when hydraulic pressure oil duct (5) when not being worn through, the detected force value of pressure detection instrument is a steady state value, and when hydraulic pressure oil duct (5) was worn out, the detected force value of pressure detection instrument obviously reduced.
The utility model provides a kind of simple in structure, low cost of manufacture, fluid pressure type abrasion detection cutter that reliability is high, this cutter can reflect the tool wear value attrition value that whether reaches capacity accurately and easily, can avoid like this or reduce to open a position checking the number of times of tool wear situation, increase the security and the high efficiency of shield-tunneling construction, reduced the shield-tunneling construction cost.

Embodiment
The structure of the fluid pressure type abrasion detection cutter in the present embodiment comprises protection sword (1), major cutting edge (2), cutter hub (3), plug screw (4), hydraulic pressure oil duct (5), wearing layer (6) as shown in Figure 1.Hydraulic pressure oil duct (5) is arranged on cutter hub (3); hydraulic pressure oil duct (5) one ends are blind end; one end is that plug screw (4) or other modes are stopped up end; one end is for connecting oil pipe end A end; the blind end of hydraulic pressure oil duct (5) is positioned between protection sword (1) and the major cutting edge (2); protection sword (1) promptly can reduce the behind wearing and tearing of dregs to major cutting edge (2), also can prevent that hydraulic pressure oil duct (5) is worn out at cutter, influences the accuracy that tool abrasion detects simultaneously behind.The most advanced and sophisticated place of hydraulic pressure oil duct (5) blind end is the limiting wear value (being the permission attrition value of cutter) of major cutting edge (2) apart from the vertical range at the most advanced and sophisticated place of major cutting edge (2), hydraulic oil pipeline interface A goes up and connects hydraulic line, be full of the hydraulic oil that has pressure in the hydraulic line that connects on hydraulic pressure oil duct (5) and the A mouth, setting pressure detecting instrument on this hydraulic line, pressure detection instrument can detect and be sealed in hydraulic pressure oil duct (5) and be connected hydraulic fluid pressure value in the hydraulic line on the hydraulic oil pipeline interface A.
When the wear extent of cutter does not reach capacity wear extent, the pressure oil that hydraulic pressure oil duct (5) and hydraulic oil pipeline interface A go up in the hydraulic line that connects is in packing state, at this moment, the pressure detection instrument shows that the hydraulic fluid pressure value under the packing state is (relevant with the initial press value, the pressurize value can be set in 14MPa～21MPa), because hydraulic pressure oil duct (5) the blind end tip distance most advanced and sophisticated apart from major cutting edge (2) is the limiting wear value (being the permission attrition value of cutter) of major cutting edge (2), so when tool abrasion reaches capacity wear extent, hydraulic pressure oil duct (5) blind end tip also is worn through simultaneously, hydraulic oil leaks, at this moment, the pressure detection instrument shows the hydraulic fluid pressure value (this value is for 0MPa or be a bit larger tham 0MPa) under the pressure release state, when finding that as the shield machine operating personnel pressure detection instrument shows under the pressure release state hydraulic fluid pressure value, the wear extent that shows cutter has reached capacity attrition value, need carry out the timely replacing of cutter, detect whether the reach capacity purpose of attrition value of tool wear value thereby reach, reach the purpose of timely replacing cutter.
