Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A tip-clearance sealing mechanism for steel pipe inner wall spiral plastic lining apparatus, comprises end cap 101, gag 107 and C-type clamp tool 108.Described end cap 101 is circular piece, circumferentially arranges a ring snap ring 102.The external diameter of the end flange of described snap ring 102 internal diameter and steel-plastic composite pipe adapts.Snap ring 102 is snapped in the circumference of steel plastic compount pipe end flanges.The circle centre position of described end cap 101 has offered lookout mouth.On described end cap 101, Zhuan has been dynamically connected and has looked at sheet 103.Suo Shu looks at sheet 103 Zhe Bi and looks at mouth.Suo Shu look at sheet 103 be circumferentially provided with bayonet socket 104.Described end cap 101 is provided with the positioning screwn 105 adapted with bayonet socket 104, described positioning screwn 105 has been threaded setscrew nut 106.
Described gag 107 adapts with the aperture of the attachment hole of steel plastic compount pipe end flanges.
Described C-type clamp tool 108 is in order to the end flange of fixing end cap 101 and steel-plastic composite pipe.Described C-type clamp tool 108, comprises C-shaped support body 116; Described support body 116 upper end is provided with folder post 109, and lower end is provided with holder 120; Described folder post 109 upper end is provided with handle 110, and middle part is provided with screw thread and passes support body 116; Described support body 116 upper end is provided with receiving cavity 115; Described receiving cavity 115 side is inclined-plane, and opposite side connects with folder post 109 and faces; Slide block 112 and spring 114 is provided with in described receiving cavity 115; Described slide block 112 side parallels with the inclined-plane of receiving cavity 115, and opposite side is provided with and the screw thread pressing from both sides post 109 and cooperatively interact, and is provided with the projection 113 paralleled with receiving cavity 115 inclined-plane in the middle part of slide block 112; Be provided with in described receiving cavity 115 and match and the groove paralleled with receiving cavity 115 inclined-plane with projection 113; Be provided with button 111 above described slide block 112, below is provided with spring 114; Described button 111 upper end exposes to support body 116; Described holder 120 is small at both ends and big in the middle, and middle part is arranged in limiting stopper 119, and bottom end face arc is arranged; Offer circular hole in the middle part of described limiting stopper 119, support body 116 is fixed at two ends; Jacking block 118 is provided with below described holder 120; Described jacking block 118 upper-end surface arc is arranged.
During work, folder post 109 presses down and close holder 120, by end cap 101 and steel-plastic composite pipe clamping.The arc diameter of holder 120 bottom surface is less than jacking block 118 upper-end surface arc diameter, therefore, when holder 120 bottom surface contacts jacking block 118 upper-end surface, holder 120 still can do certain angular adjustment, makes holder 120 upper-end surface bonded to each other with the surface of contact of caught object all the time.
This fixture energy quick clip compound body.Press the button 111, projection 113 glides along the groove of receiving cavity 115.Slide block 112 while moving down, also away from folder post 109.Now press from both sides post 109 to move down fast and make folder post 109 lower end surface touch caught object.And then release button 111, slide block 112 under the effect of spring 114 on move and near folder post 109, finally make slide block 112 and folder post 109 be threaded.At this time, then handle with sleeve 110, make the clamping that clipped object physical efficiency is more firm.
Be provided with position shelf 117 in the middle part of described support body 116, described position shelf 117 comprises left socle 121 and right support 122; Described left socle 121 and right support 122 outer end are all fixedly installed nut 126; Described nut 126 has been threaded push rod 125; The end face arc of described push rod 125 side is arranged, and opposite side cross-under has torsion bar 124; Described torsion bar 124 two ends are provided with spacing 123.
Because snap ring 102 wraps up flange, its circumference is arc, and support body 116 does not contact with snap ring 102 periphery, and when rotating clip post 109, support body 116 also can rotate thereupon.In order to prevent support body 116 from rotating, need to arrange position shelf 117.Rotate torsion bar 124, thus regulate the extended position of push rod 125 on nut 126, until the curved end of push rod 125 contacts snap ring 102 edge, thus the relative position of fixing bracket body 116 and flange.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technological scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection domain of the present utility model.
