DETAILED DESCRIPTION

[0019] The utility model will be described in further detail below in combination with the drawings of the embodiments of the utility model.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1-4 The utility model provides technical scheme: a shield machine split starting pipeline bracket, including fixed frame 1 and moving frame 2, the fixed frame 1 bottom welding has the mounting plate 3, moving frame 2 bottom is equipped with slide rail 4, and moving frame 2 is along the inside slide of slide rail 4, and moving frame 2 is parallelly arranged with fixed frame 1, the fixed frame 1 is connected with pipeline guide, and pipeline guide is equipped with several along the length direction of fixed frame 1, the inside fixed of moving frame 2 is equipped with slide 5, and slide 5 side is slidably connected with pipeline traction piece, and pipeline traction piece is equipped with several along the length direction of moving frame 2.

[0022] Among them, pipeline guide includes telescopic rod 6 fixed in the bottom of fixed frame 1, and the outer cylinder 7 is fixed at the end away from fixed frame 1 of telescopic rod 6, and the inner cylinder 8 is arranged in the outer cylinder 7, and the damping rod 9 is fixed between the outer cylinder 7 and the inner cylinder 8, and the damping rod 9 is arranged in the circumferential direction of the outer cylinder 7.

[0023] The ball 10 is rotatably connected to the inner wall of the inner cylinder 8, and the ball 10 is arranged in the circumferential direction and the length direction of the inner cylinder 8.

[0024] Meanwhile, the inclined surface 11 is arranged at both ends of the inner cylinder 8.

[0025] The pipeline guide is used for guiding the pipeline, and the required pipeline is introduced into the inner cylinder 8, and then into the inner pipeline traction piece after passing through the inner cylinder 8.

[0026] A damping rod 9 is arranged between the inner cylinder 8 and the outer cylinder 7. When the inner cylinder 8 is tilted towards the inner wall of the outer cylinder 7 due to the pulling of the pipeline, the corresponding damping rod 9 is retracted, thereby reducing the tilting speed and avoiding the pipeline from being bent due to the excessive speed during pulling. The damping rod 9 can also absorb energy during retraction, further reducing the swing amplitude of the pipeline and protecting the pipeline.

[0027] An inclined surface 11 is arranged at both ends of the inner cylinder 8. The inclined surface 11 can prevent the edges of the inner cylinder 8 from cutting or scratching the pipeline during movement.

[0028] The pipeline pulling device includes a driving wheel 12 rotating inside the slide 5. The driving wheel 12 has a driving shaft 13 fixed at the center. The driving shaft 13 is connected to a motor 14 at the end away from the driving wheel 12. The motor 14 is connected to the driving wheel 12 through a connecting frame 15. The driving shaft 13 is rotatably connected inside the connecting frame 15. The connecting frame 15 is fixed with a support plate 16 at the bottom. The support plate 16 is fixed with a first arc-shaped plate 17 at the end away from the connecting frame 15. The first arc-shaped plate 17 is oppositely arranged with a second arc-shaped plate 18. The first arc-shaped plate 17 and the second arc-shaped plate 18 are hingedly connected at the end towards the connecting frame 15. The second arc-shaped plate 18 is provided with an adjusting member on the side surface.

[0029] The adjusting member includes a rotating seat 19 fixed on the side surface of the second arc-shaped plate 18. The rotating seat 19 is hingedly connected with a piston rod 22 inside. The piston rod 22 is connected with a gas cylinder 23 at the end away from the rotating seat 19.

The lead screw is threadedly connected with the moving frame 2 outside. The guide rod 21 is slidingly connected with the moving frame 2 outside. The lead screw 25 is extended at one end out of the slide rail 4. The extended end is connected with a motor 20.

[0031] The motor 20 is driven to rotate the lead screw. Since the lead screw is threadedly connected with the moving frame 2, the moving frame 2 can slide inside the slide rail 4 when the lead screw rotates. The other end of the moving frame 2 slides with the guide rod 21, thereby adjusting the distance between the moving frame 2 and the fixed frame 1. The distance of the root pipeline to the shield device can be adjusted to avoid the pipeline from being pulled at the device end.

[0032] The motor 14 is driven to rotate the driving wheel 12, thereby adjusting the included angle between the first arc-shaped plate 17 and the inner cylinder 8. The driving of the gas cylinder 23 can drive the second arc-shaped plate 18 to rotate, change the included angle between the second arc-shaped plate 18 and the first arc-shaped plate 17, and thereby change the clamping force of the second arc-shaped plate 18.

[0033] Wherein a plurality of freely rotatable spheres 10 are arranged inside the inner cylinder 8, and when the pipeline moves, the spheres 10 can be contacted, the spheres 10 rotate, the friction between the pipeline and the inner cylinder 8 is reduced, and the pipeline can be better moved.

[0034] The working principle of the utility model: the pipeline passes through the first arc plate 17 and the second arc plate 18 after passing through the inside of the inner cylinder 8 to reach the shield device, when the pipeline is pulled, a plurality of inner cylinder 8 structures are arranged, the pipelines can be avoided to be messy, and after the pipeline is pulled, the pipeline moves left and right or up and down, then the driving connection frame 15 is driven to slide along the slide 5 inside through the driving of the motor 14, the angle of the first arc plate 17 and the inner cylinder 8 in the left and right directions is changed, when the pipeline moves left and right, the pipeline is prevented from being bent too much and being broken, and when the pipeline moves up and down, the distance between the moving frame 2 and the fixed frame 1 is changed through the driving of the motor 20, the angle of the pipeline bending in the up and down direction is adjusted, and then the pipeline is protected; when the pipeline is pulled, the second arc plate 18 is driven to rotate through the cylinder 23, the clamping force on the pipeline is changed, and after the clamping force on the pipeline is reduced, the clamping force on the outside of the pipeline is prevented from being too large and the pipeline is prevented from being easily pulled and broken.
