Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The utility model discloses a synchronous extending structure of claw is rolled up to plastic corrugated pipe winder coils claw subassembly including three group at least on the carousel 6, and it is big more to coil the claw internal diameter, and required coils claw subassembly quantity more, and figure 1, figure 2 show to be 6 groups. Each group of the coil claw components is uniformly distributed along the center of the turntable, each group of the coil claw components comprises a small bevel gear 1, the shaft part 11 of the small bevel gear 1 is provided with an external thread matched with the nut 2, the nut 2 is provided with a coil claw 3, the nut 2 is fixedly connected with the sliding block 4 and can move along a linear guide rail 5 along with the sliding block 4, and the linear guide rail 5 is fixed on the turntable; the gear head 12 of the small bevel gear 1 is engaged with the large bevel gear 7, and the large bevel gear 7 is positioned at the center of the turntable 6 and is in rotating fit with the turntable 6.

The utility model discloses a synchronous extending structure of claw is rolled up to plastic corrugated pipe winder dish, when the internal diameter is rolled up in needs adjustment, also when the circumference diameter that the claw was constituteed is respectively rolled up to needs adjustment, rotatory any one bevel pinion 1, it is rotatory all to drive big bevel gear 7, thereby it is rotatory to drive other bevel pinion 1, the axial region 11 of bevel pinion 1 is equipped with the external screw thread, with the internal thread looks adaptation of nut 2, simultaneously because

nut

2 and 4 fixed connection of slider, the unable circumferential direction of nut, bevel pinion 1's rotation can drive nut 2 along bevel pinion axial displacement, reciprocating of nut 2 drives slider 4 and removes along linear guide 5, linear guide 5 extends along 6 radial directions of carousel, the dish on the nut is rolled up the claw and is radial movement thereupon also, thereby reach the purpose of adjustment reel internal diameter. The rotation of any bevel pinion 1 can synchronously drive other coiling claws 3 to extend and retract along the radial direction of the rotary table. Of course, the purpose of synchronous radial extension of the coiling claw 3 can also be realized by directly driving the rotation of other bevel pinions 1 through the rotation of the large bevel gear 7.

After the positions of the coiling claws 3 are adjusted, the turntable 6 starts to rotate, the corrugated pipe is wound on each coiling claw 3, and each coiling claw 3 is arc-shaped and is attached to the wound corrugated pipe. Because the thread fit between the bevel pinion 1 and the nut 2 has a self-locking function, no additional locking device is needed between the bevel pinion and the nut after the position adjustment.

The turntable is also provided with a bearing seat 14, and the bearing seat 14 supports the shaft part 11 of the bevel pinion 1 to increase the stability of the bevel pinion 1.

The large bevel gear 7 is rotatably engaged with the turntable 6. the large bevel gear 7 is mounted on a shaft 10 at the center of the turntable 6 via a hole retainer 8, a bearing 9 and a shaft 10. The inner ring of the bearing 9 is pressed by a gland 12, and a screw 13 is screwed into the shaft 10 to press the gland 12 tightly.

When the inner diameter of the coiling claw is adjusted, a manual or electric driving mode can be adopted, the tail end of each bevel pinion part is provided with a wrench platform 13, the wrench platform 13 for manually clamping any bevel pinion is rotated to drive the bevel pinion 1 to rotate, the bevel pinion 7 is driven to rotate, other bevel pinions 1 are synchronously driven to rotate, and the radial position of the coiling claw is adjusted. The size of the inner diameter of the coil can be controlled electrically, a big bevel gear at the center of the turntable can be directly driven to drive all small bevel gears to rotate, the nut and the coil claw are driven to move radially, the shaft at the center of the turntable shown in figures 1 and 7 is only one example, the radial movement of the coil claw is ensured by adopting a linear guide rail, and the bearing is fixed by adopting a solid shaft. Hollow shafts may also be used, the central opening being a wire guide for the passage of wires through the control element.

Adopt this structure, cooperation electric control is different from the mechanical reducing structure of coiling claw among the prior art completely, the utility model discloses not only simple structure adjusts labour saving and time saving moreover.
