DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described from the direction and structure in the state shown in the drawings. Figures 1-8

[0025] The utility model will be described further in detail in combination with the drawings. Figures 1-8

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described from the direction and structure in the state shown in the drawings. Figures 1-8 The existing gas expansion shaft 12 pulling and inserting device cannot be adapted and adjusted according to the radius of the gas expansion shaft 12, so that when the gas expansion shaft 12 pulling and inserting device supports the gas expansion shaft 12 with unmatched diameters, the gas expansion shaft 12 will shake in the radial direction, leading to the mispositioning of the gas expansion shaft 12. To solve the above problems, a gas expansion shaft pulling and inserting device includes a support 11 and a plurality of rolling wheel assemblies 21, which are connected to the top surface of the support 11 in linear arrangement. The rolling wheel assembly 21 includes a wheel frame 211, a bevel gear 212, a spring 213 and a rotating shaft 214. The bevel gear 212 is conical. The wheel frame 211 is installed on the top surface of the support 11. The rotating shaft 214 is installed on the wheel frame 211. Two bevel gears 212 are rotationally connected to the rotating shaft 214. The concave surfaces of the two bevel gears 212 are oppositely arranged. The spring 213 is sleeved on the rotating shaft 214 and abuts between the wheel frame 211 and the bevel gear 212. The gas expansion shaft 12 abuts against the bevel gear 212. The spring 213 exerts a spring force. The two bevel gears 212 are close to each other to limit the radial displacement of the gas expansion shaft 12. The gas expansion shaft 12 is driven to enter above the support 11 and abut between the annular surfaces of the two bevel gears 212. The gravity of the gas expansion shaft 12 exerts a force on the bevel gear 212, and the spring 213 also exerts a force on the bevel gear 212. The spring 213 makes the two bevel gears 212 close to each other, and the critical point of the close is the outer periphery of the two bevel gears 212 and the gas expansion shaft 12, thereby reducing the possibility of the gas expansion shaft 12 moving in the radial direction. At the same time, through the above arrangement, the two opposite bevel gears 212 can be close to or away from each other to adapt to gas expansion shafts 12 with different diameters.

[0027] The bevel gear 212 is made of wear-resistant plastic, metal or metal-plastic material. The plastic includes PEEK, PTFE, PA and PU.

[0028] ​​Because the air shaft 12 is cylindrical, its side surface is arc-shaped. When the air shaft 12 is driven to the conical wheel 212, the side surface of the air shaft 12 abuts against the side surface of the conical wheel 212. At this time, in cross-section, the side surface of the air shaft 12 is circular, while the side surface of the conical wheel 212 is straight. This results in a single-point contact between the side surface of the air shaft 12 and the side surface of the conical wheel 212, leading to increased pressure on the conical wheel 212 and making it prone to damage. When the air shaft 12 is driven to the conical wheel 212, the air shaft 12... The side of the air shaft 12 abuts against the side of the cone wheel 212. To solve the above problem, the side of the cone wheel 212 of this utility model is set as a concave arc surface. At this time, in the cross section, the side of the air shaft 12 is circular and concave, while the side of the cone wheel 212 is arc-shaped. The air shaft 12 and the side of the cone wheel 212 are in double-point contact. When the arc of the side of the air shaft 12 is equal to the arc of the concave side, the air shaft 12 and the side of the cone wheel 212 are in line contact. Through the above setting, the pressure on the cone wheel 212 is reduced and the service life of the cone wheel 212 is improved.

[0029] When it is necessary to detach the tube from the air shaft 12, the bracket 11 needs to be driven to the transfer platform 13 so that the bracket 11 abuts against the side of the transfer platform 13. Then, the air shaft 12 is driven onto the conical wheel 212. At this time, the conical wheel 212 rotates, and the tube detaches from the air shaft 12. Finally, the tube remains on the transfer platform 13. The air shaft 12 is supported by multiple sets of conical wheels 212 through the rotating conical wheel 212, that is, the air shaft 12 is finally located above the bracket 11. However, at the moment when the bracket 11 abuts against the side of the transfer platform 13, the bracket 11 directly collides with the side of the transfer platform 13. After repeated use, this causes the collision point of the transfer platform 13 to be dented, and the collision point of the bracket 11 also deforms. In order to solve the above problems, such as Figure 2 As shown, this utility model also includes an abutment gasket 15, which is connected to one end of the bracket 11. The abutment gasket 15 is made of wear-resistant and elastic plastic, such as PU or PEEK, with a thickness of 3-8mm. The abutment gasket 15 abuts against the side of the transfer platform 13 to achieve contact between the bracket 11 and the transfer platform 13. At the moment the abutment gasket 15 abuts against the side of the transfer platform 13, the abutment gasket 15 collides with the transfer platform 13 and is buffered, thereby reducing the possibility of reduced service life of the transfer platform 13 and the bracket 11 due to collision.

[0030] As mentioned above, the air shaft 12 needs to be driven to detach the core from it. Therefore, this invention also includes a drive assembly 31, which includes a hook 311, a tie rod 312, and a collecting roller 313. The hook 311 connects to the air shaft 12, and the tie rod 312 is wound around the collecting roller 313. The collecting roller 313 is rotatably connected to the bracket 11. The hook 311 is connected to the end of the tie rod 312, causing the collecting roller 313 to rotate and drive the tie rod 312 to extend and retract, thereby pulling the air shaft 12 to roll on the conical wheel 212. The hook 311 can be connected to the air shaft 12 via a rope. The rotation of the collecting roller 313 causes the tie rod 312 to pull the hook 311 back, thus driving the air shaft 12 to detach the core from it.

[0031] A further embodiment is that the drive assembly 31 also includes a hand crank 314, which is connected to the rotation shaft of the collection roller 313. The user can rotate the hand crank 314 to drive the collection roller 313 to rotate. Another embodiment is that the hand crank 314 is replaced by a motor, which drives the collection roller 313 to rotate.

[0032] Because the position where the air shaft 12 is driven to disengage from the tube core needs to be changed according to the actual environment of the site, the height of the aforementioned position is uncertain. In order for this utility model to be adaptable to various height positions, such as... Figure 1 As shown, this utility model also includes a lifting platform 14, specifically an X-shaped lifting platform 14. The lifting platform 14 is provided with a scissor arm 141, an upper plate 142, and a base frame 143. The scissor arm 141 is connected between the upper plate 142 and the base frame 143. The scissor arm 141 drives the upper plate 142 to move vertically relative to the base frame 143. The support 11 is connected to the top surface of the upper plate 142, so that the lifting platform 14 can drive the support 11 to move vertically, that is, adjust the height of the support 11, thereby driving the height of the rolling wheel assembly 21.

[0033] Since the air shaft 12 is elongated and the bracket 11 is used to support the air shaft 12, the bracket 11 of this utility model is elongated. The roller assembly 21 is equidistantly connected to the bracket 11 along the length of the bracket 11. Through the above arrangement, the air shaft 12 can abut against the multiple sets of roller assemblies 21 on the elongated bracket 11.

[0034] When the air shaft 12 needs to be inserted into the tube core, especially when the tube core has a thin film material of a certain thickness wound on it, place the bracket 11 on the other side of the tube core, support the air shaft 12 on the conical wheel 212, and then raise the air shaft 12 to the height of the tube core. Then, follow the above method for inserting the air shaft 12 into the tube core.

[0035] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They cannot be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit of the main technical solution of this utility model should be covered within the protection scope of this utility model.
