Summary of the invention
The problem to be solved in the present invention is the deficiency overcome in background technology, a kind of shield structure end-cover fixed type kerf cutter is provided, this shield structure end-cover fixed type kerf cutter, have employed pressure monitor system, the monitoring to hobboing cutter pressurized force value can be realized, under ensureing that hobboing cutter is operated in normal construction ambient conditions.
For solving the problem, the present invention takes following technical scheme:
A kind of shield structure end-cover fixed type kerf cutter of the present invention, comprise cutter ring, voussoir, cutter hub, bearing, lining, rotating shaft, described cutter ring is fixed on the cylindrical of cutter hub by voussoir, described cutter hub is formed by bearing and rotating shaft and is rotatably connected, described lining is annular, be enclosed within the cylindrical of rotating shaft, between the inner ring of bearing, the inside circumference face that described cutter ring matches with cutter hub is provided with pressure sensor, described pressure sensor is connected with the first holding wire, described first holding wire is connected to electrode through the radial direction through hole that cutter hub is processed, the region of the periphery counter electrode of described lining is inlaid with the electric connector in annular, described electrode and electric connector form sliding-contact and are connected, the inner side of described electric connector is connected with secondary signal line, described secondary signal line is connected to junction box through the radial hole that rotating shaft is processed and the processing communicated with radial hole at the wire guide of rotating shaft inside.
A corrective measure of the present invention is: adopt insulation materials to isolate between described electric connector and lining.
Further improvement of the present invention measure is: described insulation materials is pottery.
When hobboing cutter start to contact rock carry out brokenly rock time, hobboing cutter cutter ring pressurized, now, be arranged on pressure sensor on inside circumference face that cutter ring matches with cutter hub, convert pressure signal to the signal of telecommunication, electrode is reached by the first holding wire, due to cutter hub by bearing along axis of rotation, and lining is enclosed within the cylindrical of rotating shaft, electric connector fixing on excircle of bushing face is annular, be connected so electrode and electric connector are sliding-contact, electric pressure signal is sent to electric connector, because electric connector is connected to again secondary signal line, secondary signal line is connected to junction box by the hole that rotating shaft is processed, therefore electric pressure signal is sent to junction box, and then the signal input part of shield construction system controller is delivered to by other circuit, after being calculated by control system analysis, the force value that current hobboing cutter is subject to can be presented in system screen, if exceed limit value, system alarm, operating personnel can find out failure cause accordingly, and then ensure that hobboing cutter is operated in normal construction condition and range, guarantee hobboing cutter application life.
This cover pressure monitor system all can be installed in each blade inside, adopt different holding wires, monitor the duty of each hobboing cutter, not only can understand the pressurized situation of each hobboing cutter in real time, but also the stressing conditions of whole shield cutter can be analyzed according to force value, and then for cutterhead design improve foundation is provided.
A kind of shield structure end-cover fixed type kerf cutter of the present invention, due on the inside circumference face of matching with cutter hub at the cutter ring of hobboing cutter, pressure sensor is installed, described pressure sensor is connected with the first holding wire, described first holding wire is connected to electrode through the radial direction through hole that cutter hub is processed, the region of the periphery counter electrode of described lining is inlaid with the electric connector in annular, described electrode and electric connector form sliding-contact and are connected, the inner side of described electric connector is connected with secondary signal line, described secondary signal line is connected to junction box through the radial hole that rotating shaft is processed and the processing communicated with radial hole at the wire guide of rotating shaft inside, therefore, can the stressing conditions of each hobboing cutter of Real-Time Monitoring, a kind of shield structure end-cover fixed type kerf cutter of the present invention, improve the intelligent level of shield cutter further, improve the application life of hobboing cutter, for the improvement of shield cutter is laid a good foundation, there is low cost of manufacture, easy installation, the advantages such as result of use is remarkable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of shield structure end-cover fixed type kerf cutter of the present invention, comprise cutter ring 1, voussoir 2, cutter hub 3, bearing 12, lining 8, rotating shaft 13, described cutter ring 1 is fixed on by voussoir 2 on the cylindrical of cutter hub 3, described cutter hub 3 is formed by bearing 12 and rotating shaft 13 and is rotatably connected, described lining 8 is in annular, be enclosed within the cylindrical of rotating shaft 13, between the inner ring of bearing 12, the inside circumference face that described cutter ring 1 matches with cutter hub 3 is provided with pressure sensor 4, described pressure sensor 4 is connected with the first holding wire 6, described first holding wire 6 is connected to electrode 7 through the radial direction through hole 5 of processing on cutter hub 3, the region of the periphery counter electrode 7 of described lining 8 is inlaid with the electric connector 9 in annular, described electrode 7 forms sliding-contact with electric connector 9 and is connected, the inner side of described electric connector 9 is connected with secondary signal line 11, described secondary signal line 11 is connected to junction box 15 through the radial hole 10 that rotating shaft 13 is processed and the processing communicated with radial hole 10 at the wire guide 14 of rotating shaft 13 inside.
