Abstract
The invention discloses a hobbing cutter with a wear indication function, and the hobbing cutter comprises a cutter body equipped with a cutting edge, a rotating shaft and an end cover, wherein the rotating shaft is mounted in the shaft hole of the cutter body through a bearing, the end cover is arranged outside the bearing, the hobbing cutter is provided with an inner cavity communicating from the end part of the rotating shaft to the cutting edge, and the inner cavity is connected with an oil conveying system. By virtue of the inner cavity arranged in the hobbing cutter, a pipe joint mounted on the hobbing cutter is connected with the oil conveying system, oil with a certain pressure is injected from the pipe joint and arrives at the cutting edge through the inner cavity, when the cutting edge is worn, the hobbing cutter can be subjected to the oil leakage situation and the oil pressure of the oil conveying system can change; and on the other aspect, the pipe joint is directly or indirectly connected with a pressure gauge or a pressure sensor, when the cutting edge is worn, an operator can see the pressure changes of the inner cavity in a directviewing manner, and the hobbing cutter has the advantages of accurate wear indication and simple structure.
Description
Technical field
The present invention relates to a kind of shield machine hobboing cutter, relate in particular to a kind of hobboing cutter with wearing and tearing deixis.
Background technology
Shield method is the job practices of tunneling tunnel with protecting cover special machinery (being shield machine) in broken rock or soil layer, the cutterhead of shield machine is provided with cutter, it mainly is the rotation that utilizes cutterhead, rock, soil layer etc. are ditched, rolled and fragmentation etc. by cutter, hobboing cutter is simple in structure in the shield cutter, the broken cutter that the rock amount is big, efficiency of breaking rock is high, be mainly used in the fragmentation, hard rock, the single-blade disk cutter then with its simple structure, higher efficiency of breaking rock with than the long life characteristics, is widely used in the shield machine.Yet in present shield-tunneling construction engineering, the constructor does not often have detection method because of the wearing and tearing of hobboing cutter, and can't find out the hobboing cutter that has worn and torn, will cause the wearing and tearing because of the part hobboing cutter like this, and influence the quality and the progress of whole construction.
Summary of the invention
The object of the present invention is to provide a kind of hobboing cutter, do not have the problem of blade wearing and tearing deixis with hobboing cutter, having the wearing and tearing indication accurately and advantage of simple structure to solve present shield-tunneling construction with wearing and tearing deixis.
The objective of the invention is to be achieved through the following technical solutions:
A kind of hobboing cutter with wearing and tearing deixis, comprise that cutter hub, cutter hub axis hole that blade is installed are interior by the rotating shaft of bearing installation and the end cap of bearing outer setting, described hobboing cutter is provided with an inner chamber that is communicated to blade from roller end, described inner chamber connects fuel transfer system, and described fuel transfer system is provided with pressure meter or pressure sensor.
Described inner chamber comprises the horizontal cavity that is interconnected and vertical cavity, and horizontal cavity is through to the center of hobboing cutter along axis direction from the center, end of rotating shaft, and vertically cavity extends to blade straight up from the hobboing cutter center.
Annular solid of the outside socket of described rotating shaft, and can relatively rotate each other, described annular solid is arranged on the centre position of hobboing cutter, the place, mating face of described annular solid and rotating shaft is provided with dynamic seal, described annular solid and cutter hub joint are provided with the O RunddichtringO, described blade and cutter hub junction also are provided with the O RunddichtringO, lock by key between described annular solid and the cutter hub.
Beneficial effect of the present invention is: by the inner chamber that hobboing cutter is provided with, inner chamber connects fuel transfer system, with the oil injection of certain pressure, arrive the blade place by inner chamber, when wearing and tearing appearred in the blade place, the leakage of oil situation will appear in hobboing cutter, and operating personnel can directly learn the hobboing cutter abrasion condition; On the other hand, described fuel transfer system is provided with pressure meter or pressure sensor, and when wearing and tearing appearred in the blade place, operating personnel can find out intuitively that the pressure of inner chamber changes.In conjunction with above two kinds of methods, can find out the hobboing cutter that has worn and torn accurately, have the accurate and advantage of simple structure of wearing and tearing indication.
