Shield machine be a kind of tunnel piercing special engineering machinery, modern shield excavation machine collection is light, mechanical, electrical, liquid, sensing,
Information technology has the function of to excavate and cuts the soil body, the native slag of conveying, assembled tunnel-liner, measures guiding correction etc., reliably in one
Property requirement it is high, be widely used to the Tunnel Engineering such as subway, railway, highway, municipal administration, water power.And shield machine originating and connects
Receipts are the important links in shield-tunneling construction.Currently used construction method is reinforced for the end of originating terminal and receiving terminal and diaphragm wall
Artificial abolish, but when underground utilities are more in the reinforcing scope of end and change to move when difficult, surrounding enviroment complex site is narrow and need
Another construction method is taken, i.e. steel bushing method is originated and received.When steel bushing method receives shield machine, shield machine need to be in steel bushing
It is tunneled in cylinder, has following methods at present for position monitoring of the shield machine in steel bushing：First, by the guiding on shield machine
System, the method need to pass through accurate calculate and without any overrun alarm system；Second is that the left and right sides setting two below steel bushing
A oil cylinder and idler wheel, after shield machine enters steel bushing, with oil cylinder by idler wheel jacking steel bushing a distance, prevention shield machine exists
Occurs " planting head " phenomenon in steel bushing, the method can only limit the downward posture of shield machine, and whether cannot detect shield machine
It transfinites the position reached with cutterhead.
Invention content
The purpose of the present invention is to provide the limit alarm devices tunneled in a kind of shield machine steel bushing, overcome existing shield
Driving position of the machine in steel bushing can not monitor the shortcomings that whether it transfinites in real time.
A kind of limit alarm device tunneled in shield machine steel bushing, it is characterised in that：On upper left, the right side of every section steel bushing
Upper and lower two positions of upper, lower-left, the position of bottom right four and rear end cap respectively set a connecting tube, and connecting tube is in steel bushing
Side connect one probe, for detecting posture and cutterhead in-position of the shield machine in steel bushing；Connecting tube is in steel bushing
Side outside cylinder connects a detection pipe, an electric contact pressure alarm is set in detection pipe, for the pressure in detection pipe；
A tracheae is connected in one manual ball valve of externally ported setting of detection pipe, for providing air pressure to detection pipe.
A kind of limit alarm device tunneled in shield machine steel bushing, it is characterised in that：The electric contact pressure alarm
Including an electro connecting pressure gauge, an audible-visual annunciator and a D.C. regulated power supply, for the pressure in detection pipe.
Further, detection pipe is made of the steel pipe of DN25.
Further, connecting tube is made of the steel pipe of DN25.
Further, probe is made of the cast iron pipe of DN25, and the side being connect with connecting tube is is open, another side seal
Stifled, probe length excavates radius by steel bushing internal diameter, shield machine and technology requires to determine.
Further, between connecting tube and steel bushing an inspection is first cut on steel bushing using the connection mode of welding
Gaging hole, then by connecting tube inserting hole, finally by connecting tube and steel bushing full weld.
Further, between detection pipe and connecting tube, probe and connecting tube by the way of being threadedly coupled, detection pipe and
It pops one's head in as external screw thread, connecting tube is internal thread.
It is an advantage of the invention that：The present invention can monitor whether position of the shield machine in steel bushing transfinites and when super in real time
Alarm can be sent out in time in limited time, solve the problems, such as accurately grasp shield machine position in steel bushing, reduce shield machine
Collision steel bushing and the risk that it is made to be deformed further resulting in engineering accident；Another probe uses the high cast iron materials of brittleness,
The sensitivity whether detection attitude of shield machine transfinites is improved, using the side being threadedly coupled between probe, detection pipe and connecting tube
Formula, replacement easy to disassemble.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description：
A kind of limit alarm device tunneled in shield machine steel bushing, it is characterised in that：Every section upper left of steel bushing 2, upper right,
Upper and lower two positions of lower-left, the position of bottom right four and rear end cap 201 respectively set a connecting tube 101, and connecting tube 101 is in steel
Side in sleeve 2 connects a probe 106, for detecting posture and cutterhead in-position of the shield machine 3 in steel bushing 2；
Side of the connecting tube 101 outside steel bushing 2 connects a detection pipe 102, and one electric contact pressure of setting is alarmed in detection pipe 102
Device, including 103, audible-visual annunciators 104 of an electro connecting pressure gauge and a D.C. regulated power supply, in detection pipe
Pressure；A tracheae is connected in one manual ball valve 105 of externally ported setting of detection pipe 102, for providing gas to detection pipe
Pressure.Detection pipe 102 is made of the steel pipe of DN25, and connecting tube 101 is made of the steel pipe of DN25, and probe 106 is by DN25
Cast iron pipe is made, and the side being connect with connecting tube 101 is opening, and opposite side blocks, and 106 length of probe are by 2 internal diameter of steel bushing, shield
Structure machine 3 excavates radius and technology requirement determines.Using the connection mode of welding between connecting tube 101 and steel bushing 2, i.e., first in steel
A detection hole is cut on sleeve 2, then by 101 inserting hole of connecting tube, 20mm is respectively stayed in both sides, finally by connecting tube 101 and steel
2 full weld of sleeve.Between detection pipe 102 and connecting tube 101, probe 106 and connecting tube 101 by the way of being threadedly coupled, inspection
Test tube 102 and probe 106 are external screw thread, and connecting tube 101 is internal thread.
