Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, being that well head draws liner weight during a kind of municipal pipeline photocuring disclosed by the utility model is repaired Type pulley blocks include support element, and support element is connected at least two telescopic rods, and one end of support element is provided with a dependence Notch 2 is additionally provided with drag reduction element on support element.
As shown in Figure 1, 2, support element includes two panels interval and the supporting plate 1 being oppositely arranged, and drag reduction element is located at two panels Between supporting plate 1, one end of every piece of supporting plate 1 is respectively formed there are two angle face 3, and the region between two angle faces 3 is to rely on Notch 2, the angular range in two angle faces 3 are 30 ° -120 °, and the angle in two angle faces 3 is 90 ° in the present embodiment, therefore Supporting plate 1 is whole to be presented the shape for being similar to " L ".When supporting plate 1 is supported in municipal pipeline by telescopic rod, angle face 3 its Middle one side is contacted with the inner wall of municipal pipeline vertical shaft 4, and another side is contacted with the inner wall of horizontal well 5.
Because the thickness of supporting plate 1 is smaller, in order to allow what supporting plate 1 more consolidated to be supported in municipal pipeline.Angle It is fixed on face 3 and abuts block 6, abut block 6 along three times that the size of 1 thickness direction of supporting plate is 1 thickness of supporting plate.Abut block 6 Thickness compared to supporting plate 1 is bigger, therefore area of the abutting block 6 when contacting with municipal pipeline inner wall is bigger, so that Supporting plate 1 is not easy opposite municipal pipeline and shakes.
As shown in Figure 1, 2, four connecting rods are fixed between supporting plate 1, the both ends of connecting rod are fastened by bolts part It is fixed on supporting plate 1.Wherein two connecting rods are first connecting rod 7, and it is remote that first connecting rod 7 is located at two angle faces 3 From its one end that mutually crosses, and close to the position in angle face 3, in addition two connecting rods are the second connecting rod 8, the second connecting rod 8 Then it is located at the medium position at 1 both ends of supporting plate.Drag reduction element is and to be rotatably connected on two respectively between two pieces of supporting plates 1 Pulley 9 in the second connecting rod of root 8.
When using the present apparatus, traction rope (not shown) is buckled into the annular groove in 9 circumferential direction of pulley, when traction rope is drawn When dynamic, sliding is driven rolling, so that traction rope is by smaller frictional resistance.Because shunting pressure-bearing using sister block 9, It avoids single second connecting rod 8 and 9 stress of single pulley excessive, the second connecting rod 8 and pulley 9 is made to be not easy to be destroyed.
As shown in Figure 2,3, telescopic rod totally three, wherein one is the first telescopic rod being connected between two pieces of supporting plates 1 10, in addition two are the second telescopic rod 11 on the opposite two sides of two pieces of 1 the same ends of supporting plate, and the second telescopic rod 11 passes through Revolving part is connected to supporting plate 1.
First telescopic rod 10 and the second telescopic rod 11 include supervisor 12 and extension tube 13, and supervisor 12 is logical with extension tube 13 Cross coaxial screw rod 14 to be threadedly coupled, and be threaded with adjusting nut 15 on screw rod 14, thus by rotary screw 14 or Person supervisor 12 can be adjusted the length of telescopic rod.By adjusting nut 15 to 12 one end turns of close supervisor, and when tune Section nut 15 and supervisor 12, which remain unchanged when contacting, rotates adjusting nut 15, and screw rod 14 is regulated the effect of nut 15 to remote at this time From the movement of 12 directions of supervisor, while driving extension tube 13 to the phase moved far from 12 directions of supervisor with the inner wall of municipal pipeline tightly It supports, so that the abutting of supporting plate 1 is supported on municipal pipeline inner wall.
As shown in Figure 2,3, one piece of link block 16 is connected between two pieces of supporting plates 1,16 part of link block is located at two pieces of branch Between frame plate 1, and it is fixed with supporting plate 1.First telescopic rod 10 is detachably connected with link block 16, specific type of attachment packet It includes and offers the connecting hole 17 entered for supervisor 12 on link block 16, offer edge and 17 diameter of connecting hole on link block 16 To parallel, through the spliced eye 18 of link block 16, and spliced eye 18 is connected to connecting hole 17.Supervisor 12 is inserted into connecting hole 17 One end offer along connecting hole 17 extend radially through supervisor 12 matching hole 19 match when supervisor 12 is inserted into connecting hole 17 It is corresponding with spliced eye 18 to close hole 19.One piece of fast bolt 20 is inserted into connecting hole 17, matching hole 19, then from the another of link block 16 One end is pierced by, it can be achieved that supervisor 12 connect with the quick distachable of link block 16.In addition, the axis of the first telescopic rod 10 is vertical Angle face 3 similar in Yu Yuqi.
The direction of first telescopic rod, 10 telescopic adjustment is vertical with angle face 3, therefore can extend and adjust in the first telescopic rod 10 When section by power perpendicular acting on angle face 3, so that the more firm inner wall that supporting plate 1 is supported on to municipal pipeline On;First telescopic rod 10, which is detachably connected to facilitate with link block 16, dismantles lower transport carrying for the first telescopic rod 10.
As shown in Fig. 2, revolving part includes the first hinged ear 21 for being fastened by bolts part and being rotatably connected on supporting plate 1, Perpendicular to 1 surface of supporting plate, revolving part further includes and the first hinged ear the axis that first hinged ear 21 is rotatablely connected with supporting plate 1 Second hinged ear 22 of 21 rotation connections, the pivot center between the first hinged ear 21 and the second hinged ear 22 are parallel to bracket The surface of plate 1.Second telescopic rod 11 realizes that quick distachable is connect by fast bolt 20 with the second hinged ear 22.
Because revolving part can be vertical and be parallel to two dimensions on 1 surface of supporting plate and be freely rotated, so that second stretches Contracting bar 11 can arbitrarily be adjusted with the angle between supporting plate 1, convenient for finding suitable position in municipal pipeline to supporting plate 1 It is supported.
In addition, offered on supporting plate 1 it is circular subtract matter hole 23, subtract matter hole 23 in the premise for not influencing 1 intensity of supporting plate Under reduce the quality of supporting plate 1 so that supporting plate 1 is readily transported carrying;Lifting lug 24, lifting lug are threaded on link block 16 24, for connecting with instrument, hang in the present apparatus in municipal pipeline to facilitate.
The implementation principle of the present embodiment are as follows: the present apparatus is hung in the vertical shaft 4 of municipal pipeline, telescopic rod is then mounted in phase Position is answered, telescopic rod is adjusted and supporting plate 1 is supported, so that the horizontal well 5 for being stuck in municipal pipeline by notch 2 of supporting plate 1 On the boundary corner location of vertical shaft 4.At this point, traction rope is penetrated between two pieces of supporting plates 1 and is ridden on pulley 9, then again Traction rope is pulled by instrument or manpower on the ground, when pulled, pulley 9 rolls traction rope, at this time traction rope not with Municipal pipeline is contacted but is contacted with pulley 9, to reduce the frictional force that traction rope is subject to, draws its more convenient It is dynamic, and finally realize the internal lining pipe that reparation is more easily worn in municipal pipeline.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical Within novel protection scope.
