Description
Technical field
The present invention relates to a kind of detection of the mud cake of shield machine Tu Cang and remove device.
Background technology
Mud cake be tiny sand grains, the chip that shield cutter is cut reassembled in native storehouse it is semi-consolidated
With the blocks of consolidation shape, shield machine is in tunneling process, and the formation of mud cake can not almost be avoided in native storehouse, the presence pair of mud cake
The operation of equipment has many harm, such as its load for having aggravated cutter head of shield machine and cutter, usually boring parameter is dashed forward
Become, substantially reduce efficiency of construction.Existing shield machine can not automatically detect mud cake, can only be observed by personnel's warehouse entry, and
And when find have mud cake when, it is necessary to by manpower by mud cake removal, and may not necessarily fully erased mud cake, it has the disadvantage：Can not
Mud cake is found in time, and removing mud cake work efficiency is low, and labor intensity is big.
The content of the invention
It is an object of the invention to provide a kind of detection of the mud cake of shield machine Tu Cang and remove device, to solve prior art
The mud cake that can not find in time of mud cake presence is manually found and removes, removing mud cake work efficiency is low, the problem of labor intensity is big.
The technical scheme is that：The mud cake detection of shield machine Tu Cang a kind of and remove device, it is characterised in that including
Oil cylinder, oil circuit, water pistol, water route, distance measuring sensor and controller, water pistol pass through the axle center of oil cylinder piston as piston rod,
The two ends of water pistol sealingly extend through the rear and front end of oil cylinder, and nozzle is provided with the front end of water pistol, lead in the rear end of water pistol
Electrically operated valve is crossed to be connected with high-pressure water pipe；Mounting flange is connected with the front end of water pistol；Oil circuit interface on oil cylinder passes through oil
Road is connected with hydraulic system, and hydralic pressure gauge and flowmeter are housed on the oil circuit；Being equipped with the rear end of the oil cylinder is used to detect spray
The distance measuring sensor of hydraulic giant displacement；Described distance measuring sensor and the signal output part of hydralic pressure gauge controls electricity by controller
The switch of movable valve.
It is an advantage of the invention that：Automatically mud cake can be detected and removed, i.e., is efficiently automated again；Remove the ability ratio of mud cake
Artificial removal's effect more preferably, improves operating efficiency, reduces labor intensity.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the embodiment of the present invention.
Embodiment
Referring to Fig. 1, a kind of shield machine Tu Cang of the invention mud cake detection and remove device, it is characterised in that including oil cylinder
8th, oil circuit 18, water pistol 11, water route（High-pressure water pipe 14）, distance measuring sensor 10 and controller 19, water pistol 11 lives through oil cylinder
The axle center of plug 9 is as piston rod, and the two ends of water pistol 11 sealingly extend through the rear and front end of oil cylinder 8 by sealing ring 7, in water spray
Nozzle 5 of the front end of rifle 11 provided with cone, the manually-operated gate 12 and electrically operated valve for passing through series connection in the rear end of water pistol 11（Electricity
Magnet valve）13 are connected with high-pressure water pipe 14；Mounting flange 6 is connected with the front end of water pistol 11.Two oil circuit interfaces on oil cylinder 8
15 pass through the hydraulic system of oil circuit 18 and shield machine（It is not shown）Connection, is equipped with hydralic pressure gauge 16 and flowmeter on the oil circuit 18
17.Being equipped with the rear end of the oil cylinder 8 is used to detect the displacement of water pistol 11（That is the displacement of piston 9）Distance measuring sensor
10。
The present invention according to flange 6 in use, will be arranged on the rear bulkhead 4 in the native storehouse 1 of shield machine, installation site is opposite
The inner side of preceding dividing plate 2 in native storehouse 1 easily produces the place of mud cake 3.In installation place（On rear bulkhead 4）A diameter is made a call to slightly larger than water spray
The through hole of the shower nozzle external diameter of rifle 11, installation screw is got around through hole and mounting flange 6 is fixed.
Described distance measuring sensor 10 and the signal output part of hydralic pressure gauge 16 controls electrically operated valve 13 by controller 19
Switch.It is that oil cylinder 8, which is applied, can make the minimum driving pressure of its normal movement of piston 9 to control one of method of electrically operated valve 13
Power, if（Piston）Can freely be stretched whole process, then it represents that not have mud cake in native storehouse, and the stroke of piston is surveyed by distance measuring sensor 10
Amount；If piston is met obstructions during whole process of freely stretching more than minimum driving pressure setting increment size, ranging sensing
Device 10 and hydralic pressure gauge 16 export corresponding signal to controller 19, and controller 19 then opens electrically operated valve 13, and water pistol 11 is sprayed water
Impact removes mud cake 3.
Above-mentioned control method is an example, can also use other control modes, for example：By the flow of oil circuit and
Pressure.
Before detection, the shower nozzle front end of water pistol 11 is located at（Rear bulkhead 4）One before through hole inner distance soil storehouse dividing plate 4
Set a distance.In use, the 5s that first sprayed water before pressure is applied to oil cylinder, prevents clod from blocking the outlet of nozzle 5）, and only
Operation can be detected and rinsed when cutterhead is stopped.
For the life-span of extension fixture, automatic detection with washing time is carried out when cutterhead stops operating, and is now sprayed water
Rifle 11 and mud cake 3 are not rotated.This device installs many sets in a device, and water jet is taper, can be sprayed to surrounding and front
Water is rinsed, and reaches certain impact area.
