In figure: 1-support, 2-universal wheel, 3-brake unit, 4-water filling cavity, 5-orifice plate, 6-seal groove, 7-aqueduct, 8-water pump, 9-bracing frame, 10-crossbeam, 11-slide rail, the electronic slide block of 12-, 13-electric roller, 14-steel wire rope, 15-lifting hug.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
Embodiment 1
As it is shown in figure 1, a kind of shield duct piece quality testing instrument of the present utility model, including support 1, universal wheel 2, brake unit 3, water filling cavity 4, orifice plate 5, seal groove 6, aqueduct 7, water pump 8；
The bottom of support 1 is arranged with universal wheel 2, universal wheel 2 is provided with brake unit 3, the water filling cavity 4 of arc is arranged on the top of support 1, the top of water filling cavity 4 is provided with the orifice plate 5 of arc, being provided with seal groove 6 between orifice plate 5 and shield duct piece to be detected, the water pump 8 being arranged on support 1 is connected by aqueduct 7 with water filling cavity 4；
The top of described support 1 is provided with lifting handler.
Embodiment 2
As in figure 2 it is shown, be evenly distributed with some water holes 16 on described orifice plate 5, the aperture of described water hole 16 is gradually increased by the side near the laterally closer seal groove of water filling cavity 4 one 6.
Embodiment 3
As shown in Figure 1, described lifting handler includes the bracing frame 9 being arranged on support 1 left and right sides and is arranged on the crossbeam 10 on bracing frame 9 top, crossbeam 10 is provided with slide rail 11, electronic slide block 12 it is provided with in slide rail 11, electronic slide block 12 and slide rail 11 are slidably connected, being fixed with electric roller 13 on electronic slide block 12, electric roller 13 is wound with steel wire rope 14, the end of steel wire rope 14 is fixed with lifting hug 15.
The work process of this example: during detection, described orifice plate 5, shield duct piece to be detected, seal groove 6 form a space sealed, under the effect of water pump 8, water in water filling cavity 4 enters in shield duct piece to be detected by the water hole on orifice plate 5, by observing the infiltration situation of shield duct piece water to be detected, permeability can be detected.
Water hole is evenly distributed on orifice plate 5, the pressure that test water can be identical is made to penetrate on the surface of shield duct piece to be detected uniformly, the aperture of water hole is sequentially reduced from inside to outside, the intensity of orifice plate 5 can be ensured, the direct contact surface that can increase again the water in water filling cavity 4 and shield duct piece amasss, and improves the reliability of testing result.
The setting of lifting handler so that the permeability detection of shield duct piece is more time saving and energy saving, can be automatically performed charging and discharge operation, improves detection working performance.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All impartial changes made according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
