Description
Technical field
It the utility model is related to a kind of shield machine Tu Cang mud cake detection and remove device.
Background technology
It is semi-consolidated that mud cake is that tiny sand grains, the chip that shield cutter is cut reassemble in native storehouse
With consolidation shape blocks, shield machine in tunneling process, in native storehouse the formation of mud cake can not almost avoid, the presence pair of mud cake
The operation of equipment has many harm, for example it has aggravated the load of 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 finding to have mud cake, it is necessary to by manpower by mud cake removal, and may not necessarily fully erased mud cake, its shortcoming is：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
The purpose of this utility model is just to provide a kind of shield machine Tu Cang mud cake detection and remove device, existing to solve
Technology, which manually finds and removed, can not find mud cake in time existing for mud cake, removing mud cake work efficiency is low, and labor intensity is big to ask
Topic.
The technical solution of the utility model is：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 is through the axle center of oil cylinder piston as piston
Bar, the both ends of water pistol sealingly extend through the rear and front end of oil cylinder, nozzle are provided with the front end of water pistol, in the rear end of water pistol
It is connected by electrically operated valve 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 circuit is connected with hydraulic system, and hydralic pressure gauge and flowmeter are housed on the oil circuit；It is equipped with the rear end of the oil cylinder and is used to detect
The distance measuring sensor of water pistol displacement；Described distance measuring sensor and the signal output part of hydralic pressure gauge are controlled by controller
The switch of electrically operated valve.
The utility model has the advantages that：Automatically mud cake can be detected and removed, i.e., is efficiently automated again；Remove the energy of mud cake
Power is more preferable than artificial removal effect, improves operating efficiency, reduces labor intensity.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment.
Embodiment
Referring to Fig. 1, a kind of shield machine Tu Cang of the utility model mud cake detection and remove device, it is characterised in that including
Oil cylinder 8, oil circuit 18, water pistol 11, water route（High-pressure water pipe 14）, distance measuring sensor 10 and controller 19, water pistol 11 is through oil
As piston rod, the both ends of water pistol 11 sealingly extend through the rear and front end of oil cylinder 8 by sealing ring 7 in the axle center of cylinder piston 9,
The front end of water pistol 11 is provided with the nozzle 5 of cone, in the manually-operated gate 12 and motor-driven valve that the rear end of water pistol 11 passes through series connection
Door（Magnetic 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 on oil cylinder 8
The hydraulic system that road interface 15 passes through oil circuit 18 and shield machine（It is not shown）Connection, equipped with hydralic pressure gauge 16 and stream on the oil circuit 18
Scale 17.It is equipped with the rear end of the oil cylinder 8 and is used to detect the displacement of water pistol 11（That is the displacement of piston 9）Ranging pass
Sensor 10.
The utility model in use, by according to flange 6 be arranged on shield machine native storehouse 1 rear bulkhead 4 on, installation site
The place of mud cake 3 is easily produced against the inner side of front baffle 2 in native storehouse 1.In installation place（On rear bulkhead 4）A diameter is made a call to be slightly larger than
The through hole of the shower nozzle external diameter of water pistol 11, installation screw is got around through hole and fixes mounting flange 6.
Described distance measuring sensor 10 and the signal output part of hydralic pressure gauge 16 controls electrically operated valve 13 by controller 19
Switch.One of method for controlling electrically operated valve 13 is to apply the minimum driving pressure that can make its normal movement of piston 9 to oil cylinder 8
Power, if（Piston）Can freely be stretched whole process, then it represents that not have mud cake in native storehouse, 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, such as：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 do not rotate.This device installs more sets in a device, and water jet is taper, can be sprayed to surrounding and front
Water rinses, and reaches certain impact area.
