Description
Technical field
This utility model belongs to technical field of engineering machinery, inflates more particularly, to a kind of shield machine shield tail rubber and plastic capsule close
Seal apparatus.
Background technology
Shield machine is also referred to as tunneler, is a kind of special engineering machinery of tunnel piercing.During shield machine construction, it is
Prevent subsoil water, mud and filling slurry from entering in shield storehouse, it is necessary to sealing at the shield tail of shield machine.Tail sealing it is close
Envelope effect is particularly significant, is related to construction safety, construction quality, driving speed and the impact to environment etc..Current countries in the world
Add the encapsulating method of oils and fatss using wire brush to tail sealing including the flourishing country of the science and technology such as Germany, Japan, U.S..It is this
The major defect that encapsulating method is present is that wire brush is easily damaged and more difficult replacing.The damage of wherein tail sealing wire brush is main
Including three kinds of situations：1st, wear and tear；2nd, leakage channel is produced because gap is bigger than normal during the dislocation of section of jurisdiction；3rd, when shield machine is turned, shield
Tail gap produces skew, and gap hour wire brush produces plastic deformation or squeezed bad, when gap is big, surmounts the elasticity of wire brush,
Act on wire brush loss of seal.
The content of the invention
The purpose of this utility model is to provide a kind of simple structure, easy for installation, good seal performance, the high shield of reliability
Machine shield tail rubber and plastic capsule air inflation sealing device.
The purpose of this utility model is realized by following technical proposals：
Shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model, it is characterised in that include by fixing bolt
It is arranged on one group of aerated capsule being arranged in order of shield tail, the note for being arranged in the shield tail and being connected with each aerated capsule
Trachea, is arranged in the shield tail and exports the greasing pipe being arranged between each two aerated capsule, is arranged in the shield tail
And the Grouting Pipe being connected with tail gap.
Described aerated capsule is high molecular abrasion-proof rubber-plastics material.
The aerated capsule number of one group of described aerated capsule being arranged in order is at least three.
Advantage of the present utility model：
（1）Shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model can be pressed according to formation variation with slurry is filled
Power, arbitrarily adjusts the blowing pressure of capsule, increased the reliability of sealing；
（2）The aerated capsule surface of shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model adopts macromolecule
Wear-resistant rubber-plastic material, service life can reach more than 80KM, and the service life of wire brush has been exceeded far away；
（3）Shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model, when shield machine is turned, gap of the shield tail
When changing, close to the inner portion air flow is automatically adjusted aerated capsule, makes ambient pressure always consistent, is not in as steel
Wire brush it is the same gap hour with regard to squeezed evil idea or produce plastic deformation, when gap is big because more than wire brush elastic limit lose
Effect；
（4）Inflation, is full of between capsule in shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model, its capsule
Oils and fatss, seal safe and reliable, will not produce leakage channel as wire brush sealing；
（5）Shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model is easy for installation, compact conformation, due to filling
Gas capsule is an entirety, and with bolt the shield tail of shield machine is fastened on, without adjusting.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model, it is characterised in that including logical
One group of aerated capsule being arranged in order that fixing bolt 15 is arranged on shield tail 11 is crossed, is arranged in the shield tail 11 and is filled with each
The air injection pipe 1,2 and 3 that gas capsule is connected, is arranged in the shield tail 11 and exports and be arranged between each two aerated capsule
Greasing pipe 7 and 8, the Grouting Pipe 9 for being arranged in the shield tail 11 and being connected with tail gap 10.
Described aerated capsule is high molecular abrasion-proof rubber-plastics material.
The aerated capsule number of one group of described aerated capsule being arranged in order is at least three.
Shield machine shield tail rubber and plastic capsule air inflation sealing device of the present utility model can replace original wire brush to seal, close
Envelope is safe and reliable, now describes its operation principle as three as embodiment using aerated capsule number：Three aerated capsules are respectively
Aerated capsule I 4, aerated capsule II 5 and aerated capsule III 6, are fixed on the bottom of shield tail 11, wherein inflating by fixing bolt 15 successively
Capsule III 6 is located at the caudal end of shield tail 11, and aerated capsule II 5 is located at the centre of aerated capsule I 4 and aerated capsule III 6, therefore
Between aerated capsule I 4 and aerated capsule II 5 formed before between 13, between aerated capsule II 5 and aerated capsule III 6 formed after between
14；What is be connected with three aerated capsules has three air injection pipe 1,2 and 3, by this three air injection pipe 1,2 and 3 respectively to three
Gas injection in aerated capsule, compressed air is injected into after aerated capsule I 4, aerated capsule II 5 and aerated capsule III 6, aerated capsule
Expand between shield tail 11 and section of jurisdiction 12, produce sealing function；Greasing pipe 7 is connected with front 13, with rear 14 note is connected with
Fat pipe 8, by inject into greasing pipe 7 and greasing pipe 8 seal grease will front between 13 and it is rear between 14 full of seal grease, while close
Gap of the oil sealing fat full of section of jurisdiction 12, to the sealing of section of jurisdiction 12 and lubrication；Grouting Pipe 9 is connected with tail gap 10, by note
Slurry pipe 9 to the injection filling slurry of tail gap 10, shield machine just can normally run.Aerated capsule be high molecular abrasion-proof rubber-plastics material, bullet
Good, the life-span length of property, sealing effectiveness is safe and reliable.
This utility model is simple and compact for structure, easy for installation, according to formation variation and can fill slurry pressure, arbitrarily adjusts capsule
The blowing pressure, increased the reliability of sealing；Because aerated capsule surface adopts high molecular abrasion-proof rubber-plastics material, service life
More than 80KM is can reach, the service life of wire brush has been exceeded far away；When shield machine is turned, gap of the shield tail changes
When, close to the inner portion air flow is automatically adjusted aerated capsule, makes ambient pressure always consistent.
