Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 1 to 5, the Novel shield machine 100 of the present embodiment comprises shield body 1 and excavation portion 2, is provided with separating part 3 in described excavation portion 2, and separating part 3 upper and lower end fixes earth pipe 4 and discharge pipe 5 respectively.Be provided with opening portion 31 in the middle part of separating part 3, opening portion 31 is communicated with the native storehouse 21 in excavation portion 2.Earth transmission mechanism 6 in shield body 1 is communicated with native storehouse 21.Front end, described excavation portion 2 is provided with cutter head assembly 7, and described shield body 1 is provided with section of jurisdiction erecting device 8, and section of jurisdiction 81 assembles by section of jurisdiction erecting device 8.Be provided with junction plate 9 between described excavation portion 2 and shield body 1, described excavation portion 2 can relative junction plate 9 stretching motion with shield body 1.Cutter head control device 11 is provided with in described shield body 1, first mobile device 12 and the second mobile device 13, described cutter head control device 11 comprises multiple swing component 111, described swing component 111 two ends connect excavation portion 2 and shield body 1 respectively, described first mobile device 12 comprises multiple first projectiles 121 and multiple positioner, described first projectile 121 two ends connect excavation portion 2 and shield body 1 respectively, described positioner is scalable and protrude from outside shield body 1, described second mobile device 13 is arranged in shield body 1, and it comprises multiple second projectile 131.In the present embodiment, first, second projectile 121,131 described is jack.Technique scheme improves the travelling performance of shield machine, in underground Tu Shi unstable region operation, can effectively improve the efficiency of construction of shield machine.
As shown in Figures 1 to 5, further, described shield machine 100 also comprises hydrologic monitoring device 10, and hydrologic monitoring device 10 to be arranged in described excavation portion 2 and to arrange around described opening portion 31, thus enable operating personnel understand underground hydrological information, adjust constructure scheme in time according to hydrologic regime.Described second projectile 131 rear end is provided with expansion link 132, and described expansion link 132 can lean on section of jurisdiction 81, thus makes the second projectile 131 to obtain the strong point.Described cutter head assembly 7 comprises cutterhead 71, multiple transmission device 72 and power set 73, and described transmission device 72 is connected with cutterhead 71.When being unfavorable for the soil layer excavated if run into, described swing component 111 can be utilized to drive excavation portion 2 to be with movable knife disc 71 to go to other excavation directions, thus avoid damaging underground pipeline, thus produce security risk.Described positioner comprises the first positioner 122 and the second positioner 123, first location 122 devices are arranged on shield body 1 side, and the second location 123 devices are arranged on side, excavation portion 2.
When shield machine 100 is when tap point carries out digging operation (as shown in Figure 5), described first positioner 122 outwards top is pressed in tunnel wall, and shield body 1 is maintained static; It is fixed support point that described first projectile 121 is fixed on shield body one end, makes the other end of the first projectile 121 advance excavation portion 2 to be with movable knife disc 71 to excavate mudstone and advances.After the first projectile 121 extends to the end, described second positioner 123 outwards top is pressed in tunnel wall, and excavation portion 2 is maintained static, and described first positioner 122 bounces back, and the first projectile 121 shrinks simultaneously, thus pulls shield body 1 near excavation portion 2.Circulate with this, advanced in excavation limit, shield machine 100 limit.
When shield machine 100 is not at digging operation (as shown in Figure 1), when it advances, the expansion link 132 of described second mobile device 13 is resisted against on the section of jurisdiction 81 in tunnel, as the strong point; When shield body 1 moves forward, drive junction plate 9 that excavation portion 2 is advanced together, when expansion link 132 is elongated to ultimate range, it is oppositely retracted in the second projectile 131, described section of jurisdiction erecting device 8 assembles section of jurisdiction 81 in tunnel, thus progressively component tunnel perisporium, circulation performs above-mentioned steps to tap point.
The Novel shield machine of the present embodiment effectively can must improve the travelling performance of shield machine, makes its more accurately safer advance; In addition, when faced by be unfavorable for excavation regions time, can excavation direction be changed, thus avoid produce security risk.It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
