Embodiment
In order to monitor the abrasion condition of all edge doctors 1, the present invention adopts the ultrasonic thickness test device to alloy head thickness measure on all edge doctors 1 and by blue teeth wireless transmission aspect data to be reached in the shield machine, read by computer, monitor the abrasion condition of all edge doctors 1.
On cutterhead, 32 symmetry in all edge doctors 1 chosen 8 as detecting cutter, detect through the ultrasonic thickness test device, send by the Bluetooth signal transmitter from detecting the signal that cutter draws; In shield machine, Bluetooth Receiver is set and data are reached the anterior shield rear by cable directly over before the shield and read.
Shield machine cutter wear monitoring device mainly is made up of ultrasonic thickness test device, Bluetooth signal emitter and Bluetooth signal receiving trap:
(1) ultrasonic thickness test device: the ultrasonic thickness test device is measured the thickness of metal by ultrasonic probe, probe diameter 15mm, and length 25mm, signal wire standard line length 1.5m, probe is installed in all edge doctors 1; The data read pen recorder can be preserved 5000 groups of data, can setting measurement interval time, by per hour testing carbide button thickness one time, can guarantee 200 days data, satisfy the monitoring in the peripheral scraper blade life phase.
(2) Bluetooth signal emitter and receiving trap: Bluetooth signal emitter and thickness measuring data read pen recorder integrate, be equipped with lithium battery, assurance work duration is more than 3 months, adopt Bluetooth signal emission data, as the wireless portion fault also can by personnel carry that the data fetch equipment band compresses into that the storehouse is read wear data or will data read pen recorder 5 take out after read, the installation site synoptic diagram of data read pen recorder 5 is as shown in Figure 1.
The Bluetooth signal receiving trap is installed in anterior shield the place ahead, and its electricity consumption and signal wire transfer to the anterior shield master-control room by anterior shield.
(3) the installation protection of tool wear monitoring device on all edge doctors 1 of shield machine:
Week, edge doctor 1 was before the welding alloy piece, on the tool matrix of alloy block bottom, bore 15mm through hole 12, hole depth is determined according to probe 7 length, according to the tool wear situation, the serious wear position becomes miter angle with cutter axis, therefore through hole 12 is 45 degree with 1 time cutter edge of all edge doctors angle, as shown in Figure 2.
Be adjacent to side fluting 8 at all edge doctors 1 and tool rest, groove width 15mm, length 26mm guarantee that probe 7 can put down, and groove 8 guarantees to reach 15mm through hole 12 positions deeply.Signal wire 4 can be drawn simultaneously.As shown in Figure 3.
At the punching of cutter opposite side (this hole is by a cutter bolt hole), diameter 16mm is near the screw thread of probe 7 one sides processing M16.
Probe 7 installation and protection: through hole 12 inside are cleared up, and blown clean with pressure-air, smear couplant (butter), will pop one's head in 7 is installed in the 15mm through hole 12 by groove 8, and signal wire 4 is drawn by groove 8.In probe 7 rear mounting spring, the spring bottom adds the fluid sealant rear enclosed with flat head screw.In groove 8, smear fluid sealant, and pile with the groove sealing with solder stick or phenolics after adding rubber blanket.After week, edge doctor 1 was installed on the tool rest, there be not the problem that comes off of wearing and tearing in groove 8 and signal wire 4 between cutter and tool rest, and behind fastening cutter bolt, the cutter bolt can guarantee that also probe compresses flat head screw and also can not take place to wear and tear and come off.
