The specific embodiment
As shown in Figure 1, telescoping mechanism 3 adopts the cylinder piston pair, and the cylinder piston pair comprises cylinder 32, flexible piston rod 31 under cylinder 32 promotes, and gripper shoe 2 bottom surfaces just are fixedly connected on the piston rod 31 of cylinder 32, and cylinder 32 is fixed on the fixed mount 71.After cylinder 32 ventilations, piston rod 31 is released arc gripper shoe 2 towards plastic pipe 1 inwall direction, push the Electric thermal smelting belt 6 that covers plastic pipe 1 inwall until arc gripper shoe 2, Electric thermal smelting belt 6 and plastic pipe 1 are fitted tightly and convenient welding, after treating that Electric thermal smelting belt 6 is welded to plastic pipe 1 inwall, cylinder 32 pulls back gripper shoe 2 after oppositely ventilating, and it is separated with Electric thermal smelting belt 6.Cylinder piston pair in the present case can use also that oil cylinder piston is secondary to be replaced, and action principle is identical, can realize the release of arc gripper shoe 2 equally and retracts.
As shown in Figure 2, telescoping mechanism 3 adopt regulate screw pairs can the pushing tow or the gripper shoe 2 of pulling back, screw pair comprises leading screw 31, nut 32, rotating threaded shaft 31, gripper shoe 2 is released towards plastic pipe 1 inwall direction, push the Electric thermal smelting belt 6 that covers plastic pipe 1 inwall until gripper shoe 2, Electric thermal smelting belt 6 and plastic pipe 1 are fitted tightly and convenient welding, after treating that Electric thermal smelting belt 6 is welded to plastic pipe 1 inwall, return screw mandrel 31, gripper shoe 2 is pulled back, it is separated with Electric thermal smelting belt 6.The quantity of screw pair is by the shape and the length decision of the gripper shoe 2 of arc, the general quantity of screw pair that adopts is no more than 12, this telescoping mechanism 3 need not source of the gas and power supply, only needs the artificial bracing or strutting arrangement that promotes just can advance in plastic pipe 1, is convenient to operation in the hole.
In order to make bracing or strutting arrangement adapt to the plastic pipe 1 of other shapes, the radian of a plurality of gripper shoes 2 that are provided with on bracing frame 7 also can be different, and for cross section symmetrical plastics side tubing 1, the gripper shoe 2 of identical radian measure also is symmetrical arranged and adapts to this kind plastic pipe 1.
Shown in Fig. 3,4,5, but described elasticity top board 5 is the thin arc of deformation and recovery, but for example have the macromolecular material plate of deformation bending and the metal sheet that can restore, anti-high temperature and folding more than 200 ℃ etc., described elasticity top board 5 detachably is fixed on the gripper shoe 2 plate faces.Elasticity top board 5 set-up modes have multiple: a kind of is elasticity top board 5 radially is arranged on gripper shoe 2 along plastic pipe 1 both sides, described elasticity top board 5 comprises fixed part and extension, the fixed part of described elasticity top board 5 is fixed on the plate face of gripper shoe 2, perhaps be fixed on the both sides of the edge of gripper shoe 2, fixed form can be spirally connected, pin connection, clamping etc., can elasticity top board 5 is fixing during use, the time spent can not pull down.Described extension extends to outside the gripper shoe 2, and the radian of elasticity top board 5 is identical with gripper shoe 2 radians of being fixed, also can be different.The elasticity top board 5 that is installed on the gripper shoe 2 can apply certain pressure to Electric thermal smelting belt 6 along even all around, and adapts to the plastic pipe local deformation, and Electric thermal smelting belt 6 is integrally combined with plastic pipe 1 inwall better.
Another kind is that elasticity top board 5 is over against gripper shoe 2 panel settings, and size is identical with gripper shoe 2 or greater than the plate face of gripper shoe 2, the radian of elasticity top board 5 is slightly less than gripper shoe 2 radians, and on the outer panel faces that elasticity top board 5 is fitted by locating part spacing that be fixed on gripper shoe 2 and Electric thermal smelting belt 6, locating part is the slide block that is provided with of elasticity top board 5 bottom surfaces, has chute on gripper shoe 2 plate face, and slide block cooperates and slides in chute and can not be deviate from from chute by chute is spacing.When elasticity top board 5 roof pressures distortion, just in chute, the be slidingly matched distortion of elasticity top board 5 of slide block.Because elasticity top board 5 radians are smaller, then during gripper shoe 2 roof pressures, at first be that elasticity top board 5 roof pressures to Electric thermal smelting belt 6 local deformation that deformation adapts to plastic pipe 1 take place, and also compress between roof pressure Electric thermal smelting belt 6 back elasticity top boards 5 and the gripper shoe 2, pressure is passed to Electric thermal smelting belt 6.When not using elasticity top board 5, slide block can be removed in chute, installation gets final product during use.
Shown in Fig. 3,4,5,6, gripper shoe 2 and the corresponding one by one setting of telescoping mechanism 3, each gripper shoe 2 is with telescoping mechanism 3 detachable grafting and by locking piece 4 lockings.The mode of pegging graft can be that described elasticity top board 5 bottom surfaces are provided with connection-peg, and described telescoping mechanism 3 correspondences are provided with spliced eye, and connection-peg is engaged in the spliced eye; Also can be that 2 bottom surfaces of gripper shoe described in the present embodiment are provided with contiguous block 21, contiguous block 21 be provided with spliced eye 22, and the end correspondence of described telescoping mechanism 3 is provided with connection-peg 36, and connection-peg 36 is engaged in the spliced eye 22.No matter which kind of mode, described locking piece 4 all is to be included in the limited block 41 that is spirally connected on spliced eye 22 walls, one of horizontally set circle stopper slot 42 on described connection-peg 36 outer walls, described limited block 41 grafting roof pressures lock gripper shoe 2 and telescoping mechanism 3 in stopper slot 42.Screw limited block 41 roof pressure stopper slots 42 and promptly lock the two and be fixed together, reverse rotation limited block 41 can unlock, and gripper shoe 2 can be separated with telescoping mechanism 3.The gripper shoe 2 that this structure can be used to change different radians is on the one hand deacclimatized the welding of the plastic pipe 1 of different tube diameters, the gripper shoe 2 of different radians can also be arranged on the other hand in the device, adapts to oval or other non-just round tubing.When plastic pipe 1 is ellipse, can adjust gripper shoe 2 at the different radian of ellipse, and the gripper shoe 2 of identical radian measure is symmetrical arranged, adapt to elliptical shape.And the length of gripper shoe 2 also can be different, and the gripper shoe 2 of different radians, different length has improved the range of application of bracing or strutting arrangement according to plastic pipe 1 shape setting, and can better adapt to and compress Electric thermal smelting belt 6, improve welding quality.
Equally, the described telescoping mechanism 3 of present embodiment also may be selected to be cylinder piston pair, oil cylinder piston pair or screw pair.They are connected with embodiment 1 with gripper shoe 2, do not repeat them here.
