Description
Technical field
The utility model relates to a kind of full face tunnel boring machine swivel joint in full face tunnel boring machine field and pipeline connecting box maintenance unit.
Background technology
Along with the development of domestic full face tunnel boring machine, increasing tunnel and subway adopt full face tunnel boring machine to construct, and get more and more along with construction works, the problem exposed also more and more regularization.Swivel joint is the important component part of full face tunnel boring machine, no matter be soil pressure, slurry balance shield or hard rock mole, all need to utilize swivel joint and pipeline connecting box by water, swell soil or other medium transport to cutterhead-region, exploitation cabin to improve dregs so that tunnel smoothly.Excavate the shock of dregs in cabin when bias during owing to installing or construction, job site often occurs the situation that swivel joint and pipeline connecting box cut off the face of conjunction bolt causing leakage.Owing to limitting in underground construction space, also need Operating Pressure sometimes, when the situation of leaking occurs, maintenance and difficulty thereof, even if keeped in repair, because 2 leakages that eccentricity issues causes also often occur.Therefore, developing a kind of full face tunnel boring machine swivel joint and pipeline connecting box maintenance unit is a new problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is to provide a kind of full face tunnel boring machine swivel joint and pipeline connecting box maintenance unit, structural volume is little, the phenomenon of swivel joint " whipping " can not be caused, make seal wear-resistant damage the life-span high, the maintenance unit that Operating Pressure requires can be met.
The purpose of this utility model is achieved in that a kind of full face tunnel boring machine swivel joint and pipeline connecting box maintenance unit, comprise the first positioning tube, slip cap, first retainer ring, pressure ring, second retainer ring, second positioning tube, the first retainer ring and the second retainer ring that play the effect of the centre of location are arranged in main driving by hinged bolts, slip cap is arranged on the first retainer ring and the second retainer ring by pressure ring and socket screw, the first positioning tube working to reorientate fixed head center of rotation is connected with the fixed head of pipeline connecting box through slip cap with the second positioning tube.
Main points of the present utility model are its structure.Its operating principle is, in work progress, the center rotor of swivel joint rotates along with the rotation of cutterhead together with pipeline connecting box.When running into the situation that swivel joint and pipeline connecting box mating face are leaked in tunneler construction, cutting off and the distortion of connecting box often along with mating face bolt, at this time simply changing bolt can not the normal use of equipment, because connecting box distortion can cause mating face to occur, angle causes the situation of seal failure.Simultaneously, the distortion of connecting box the center of rotation of connecting box can be caused not overlap with the center of rotation of swivel joint and situation, if ignored, simply swivel joint and connecting box are welded or be fixed together, when cutterhead rotates time, will cause the phenomenon of swivel joint " whipping ", make sealing wear, the life-span sharply reduces.For above situation, the reparation of problem includes following three aspects: 1, the replacing of bolt; 2, the distortion of connecting box; 3, the relocating of swivel joint center of rotation and connecting box center of rotation.
Full face tunnel boring machine swivel joint and pipeline connecting box maintenance unit are compared with prior art, have structural volume little, the phenomenon of swivel joint " whipping " can not be caused, make seal wear-resistant damage the life-span high, the advantage such as maintenance unit that Operating Pressure requires can be met, will be widely used in full face tunnel boring machine field.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to accompanying drawing, a kind of full face tunnel boring machine swivel joint and pipeline connecting box maintenance unit, comprise the first positioning tube 1, slip cap 2, first retainer ring 3, pressure ring 4, second retainer ring 5, second positioning tube 6, the first retainer ring 3 and the second retainer ring 5 that play the effect of the centre of location are arranged in main driving by hinged bolts, slip cap 2 is arranged on the first retainer ring 3 and the second retainer ring 5 by pressure ring 4 and socket screw, the first positioning tube 1 working to reorientate fixed head center of rotation is connected with the fixed head of pipeline connecting box through slip cap 2 with the second positioning tube 6.
Be described in further detail the utility model below:
Allowing pressurized maintenance step:
The first step, adapter retreats to the second retainer ring 5 position but not exclusively exits (maintenance sealing), again swivel joint is exited after the closure of openings of the first retainer ring 3 position completely with flange, after swivel joint exits, the first stationary magazine creel 1 is put into, by the closure of openings of flange by the second retainer ring 5 position.Remove the flange of the first retainer ring 3 position, the first positioning tube 1, slip cap 2, first retainer ring 3, pressure ring 4 are in place by position shown in Fig. 1.Second step, removes and damages bolt, is opened by the weld seam plane of the fixed head of pipeline connecting box in scope a-quadrant, with the first stationary magazine creel 1 for benchmark, the position of adjustment fixed head and pipeline, makes the center superposition of fixed head center of rotation and the first positioning tube 1, is again welded and fixed plate and connecting box.3rd step, remove slip cap 2, first retainer ring 3, pressure ring 4, by the closure of openings of flange by the first retainer ring 3 position, remove the flange of the second retainer ring 5 position, take out stationary magazine creel 1 and reinstall swivel joint, finally remove the flange of the first retainer ring 3 position, swivel joint and connecting box fixed head are again fixed closing, maintenance completes.
Normal pressure maintenance step:
The first step, removes swivel joint, slip cap 2, pressure ring 4, second retainer ring 5, second positioning tube 6 is pacified being in place by figure.Second step, removes and damages bolt, is opened by the weld seam plane of the fixed head of pipeline connecting box in scope a-quadrant, with the first stationary magazine creel 1 for benchmark, the position of adjustment fixed head and pipeline, makes the center superposition of fixed head center of rotation and the first positioning tube 1, is again welded and fixed plate and connecting box.3rd step, remove slip cap 2, pressure ring 4, second retainer ring 5, second positioning tube 6, reinstall swivel joint and fix with connecting box fixed head, maintenance completes.
