[0020] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0021] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.
[0022] An adjustable-size pipe conveying roller device, such as Figures 1-3 As shown, the system includes a base 2, with movable seats 3 staggered at its left and right ends. The movable seats 3 are slidably connected to the base 2 via a rod 13 and a pre-drilled sliding hole (not shown) on the side of the base 2 in the left-right direction. The inner wall of the sliding hole has a threaded hole (not shown) penetrating the outer surface of the base. The threaded hole is equipped with a first positioning bolt (e.g., for locking the rod and the sliding hole relative to each other). Figure 2 As shown in the figure (not marked, the positions of the positioning bolts and sliding holes can be set as needed in actual application), the top of the movable seat 3 is provided with a telescopic rod 4 arranged longitudinally. The tops of the two telescopic rods 4 are respectively connected to the first roller body 7 and the second roller body 10. The front and rear sides of the upper surface of the base 2 are respectively provided with straight sliding grooves 9 along the transverse direction. The sliders 8 are slidably connected in the straight sliding grooves 9. The two ends of the central axis of the first roller body 7 and the second roller body 10 are respectively hinged to the tops of the corresponding sliders 8 and the telescopic rods 4. The first roller body 7 and the second roller body 10 are arranged crosswise and staggered in the front-rear direction.
[0023] Furthermore, such as Figures 1-3 As shown, a pad 1 is fixedly provided on the left and right ends of the lower surface of the base 2. The outer end of the pad 1 extends out of the left or right end of the base 2, and the front and rear ends of the pad 1 extend out of the front and rear ends of the base 2, respectively.
[0024] Furthermore, such as Figure 1 , 2 As shown, the lower end of the movable seat 3 is slidably connected to the upper surface of the pad 1.
[0025] Furthermore, such as Figures 1-3 As shown, a stiffening rib plate 12 is also fixedly connected between the upper end of the movable seat 3 and the lower part of the outer wall of the telescopic rod 4 to enhance the stability of the telescopic rod structure.
[0026] Furthermore, such as Figure 2As shown, the telescopic rod 4 includes a sleeve 41 and a support rod 42. The bottom end of the sleeve 41 is fixedly connected to the top end of the movable seat 3. The inner surface of the sleeve 41 is provided with an internal thread, and the outer surface of the support rod 42 is provided with an external thread. The lower part of the support rod 42 is screwed into the sleeve 41. The top end of the support rod 42 is rotatably connected to a first hinge seat. The upper and lower ends of the first hinge seat are respectively provided with limiting rings 44. The two limiting rings 44 are respectively fixedly sleeved on the outer surface of the support rod 42. The upper ends of the central shafts of the first roller body 7 and the second roller body 10 are respectively hinged to the corresponding first hinge seats.
[0027] Furthermore, such as Figure 1 , 2 As shown, the slider 8 has a cubic structure, and a second hinge seat is provided at the top of the slider 8. The lower ends of the central axes of the first roller 7 and the second roller 10 are respectively hinged to the second hinge seat.
[0028] Furthermore, such as Figure 1 , 2 As shown, a handle 43 is also provided on the top of the side wall of the support rod 42.
[0029] Furthermore, such as Figure 1 , 2 As shown, the first hinge seat includes a collar 5 rotatably connected to the support rod 42 and a first hinge seat body 6 fixedly connected to the outer wall of the collar 5. The collar is provided with a threaded hole (not shown in the figure), and the collar 5 and the support rod 42 are fixedly connected by a second positioning bolt passing through the threaded hole.
[0030] The working principle of this new type:
[0031] 1. This new type of roller is designed with the first roller and the second roller arranged in a cross configuration and staggered front to back. This configuration allows the first roller and the second roller to have a longer length within a limited space. When the width needs to be adjusted, the moving seat is pulled outward by a certain distance and then the position of the moving seat is fixed by the first positioning bolt. At this time, the first roller and the second roller still maintain a sufficiently small gap to ensure the support effect on the pipe. It is also compatible with pipes of different outer diameters.
[0032] 2. It is known that pipeline transportation requires mounting on a conveying roller device, that is, mounting between the top of the first roller and the second roller. Multiple new types of support pipes are used to pull the pipes back and forth to achieve transportation within a certain distance.
[0033] 3. Since the first and second rollers of this new type have sufficient adjustment length, the spatial state between the first and second rollers can be changed by synchronously raising or lowering the telescopic rod. This allows for a certain size adjustment function without adjusting the moving seat, thus adapting to pipes with different outer diameters. If the pipes still cannot be adapted, the position of the moving seat can be adjusted.
