[0017] The present invention has at least the following beneficial effects:

[0018] First, this invention separates multiple guardrail posts by setting an adjusting plate, a lifting assembly, and a driving unit to facilitate the guardrail posts entering the corresponding positions on the transfer frame. Second, this invention adjusts the distance between the first positioning plate and the second positioning plate by setting an adjusting assembly and multiple sets of first gears to limit the movement of multiple guardrail posts, allowing them to smoothly enter the transfer frame. Third, by setting a lifting interval to drive the adjusting plate to move up and down, not only can the guardrail posts be smoothly positioned between the first and second positioning plates when the adjusting plate moves upward, but also when the adjusting plate moves downward, it can separate the multiple guardrail posts by positioning the adjusting plate between them.

[0019] Secondly, by setting up a first rotary motor, a positioning cylinder, a sliding rod, and a second gear, the present invention can adjust the distance between the adjusting plate and the first positioning plate, between the adjusting plates, and between the adjusting plate and the second positioning plate in one direction so that it can be applied to guardrail posts of different diameters.

[0020] Third, by setting a first baffle and a second baffle, the present invention enables the second gear to better adapt to changes in the position of the first gear, thus preventing the first gear from disengaging from the second gear. The present invention, by setting a connecting plate, a fourth slide rail, a fourth slider, a drive rod, a first telescopic motor, and a fixing ring, enables not only the up and down movement of the drive adjustment plate, but also the movement of the adjustment plate toward or away from the first positioning plate.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0029] like Figure 1-6 As shown, the present invention provides a composite coated steel guardrail production line equipment, comprising:

[0030] The conveyor has a rotatable transfer frame 12 at its end. The transfer frame 12 is provided with a plurality of limiting plates 15 spaced apart. The transfer frame 12 is provided with a plurality of crossbars 35 spaced apart, and the crossbars 35 are lower than the limiting plates 15.

[0031] The adjustment mechanism includes a first positioning plate 4 located on one side of the conveyor, a second positioning plate 6 movable relative to the first positioning plate 4, two sets of adjustment components, and a lifting component. Multiple adjustment plates 5 are provided between the first positioning plate 4 and the second positioning plate 6. The two sets of adjustment components are respectively located at both ends of the adjustment plates 5. Each adjustment component includes a first support 3 mounted on the conveyor, multiple fixed rods, and a drive unit. One fixed rod is connected to the first support 3, and the remaining fixed rods are connected to the multiple adjustment plates 5 one-to-one. A first nut 21 is rotatably mounted on the fixed rod, and a matching first threaded rod 24 is provided inside the first nut 21. One first threaded rod 24 is connected to the second positioning plate 6, and the remaining first threaded rod 24 is connected to its adjacent adjustment plate 5. A first gear 23 is coaxially mounted on the first nut 21. The drive unit drives the multiple first gears 23 to rotate, and the lifting component drives the multiple adjustment plates 5 to move up and down. When the distance between the first positioning plate 4 and the second positioning plate 6 is at its maximum, the multiple adjustment plates 5 correspond one-to-one with the multiple limiting plates 15.

[0032] In this technical solution, the transfer frame 12 is set using existing technology, that is, a fourth support is set at the end of the conveyor, the transfer frame 12 is hinged on the fourth support, and the transfer frame 12 can be rotated from a horizontal state to a vertical state or from a vertical state to a horizontal state by setting a fourth telescopic cylinder; the crossbar 35 is set horizontally, the conveyor includes a conveyor frame 1 and multiple rollers 2 set on the conveyor frame 1 to drive the guardrail posts to move, the limiting plate 15 is set along the moving direction of the guardrail posts; the first positioning plate 4, the second positioning plate 6, and the adjusting plate 5 are all set along the conveying direction of the conveyor; the fixed rod and the first threaded rod 24 are perpendicular to the conveying direction of the conveyor.

[0033] During use, when multiple guardrail posts are located between the first positioning plate 4 and the second positioning plate 6, the distance between the first positioning plate 4 and the second positioning plate 6 is adjusted by the first gear 23 until the distance between the first positioning plate 4 and the second positioning plate 6 is slightly greater than the sum of the diameters of the multiple guardrail posts. Then, the adjusting plate 5 is moved downward by the lifting assembly until the multiple adjusting plates 5 are inserted between the multiple guardrail posts respectively. Then, the second positioning plate 6 is moved to the position where the distance between the second positioning plate 6 and the first positioning plate 4 is the maximum. At this time, the adjusting plate 5 corresponds to the limiting plate 15, and the multiple guardrail posts enter the multiple limiting plates 15 one by one. After the operation is completed, the adjusting plate 5 is moved upward to the highest position.

[0034] By adopting this technical solution, the present invention separates multiple guardrail posts by setting an adjusting plate 5, a lifting assembly, and a driving unit to facilitate the guardrail posts entering the corresponding positions of the transfer frame 12; the present invention adjusts the distance between the first positioning plate 4 and the second positioning plate 6 by setting an adjusting assembly and multiple sets of first gears 23 to limit the multiple guardrail posts so that they can smoothly enter the transfer frame 12; by setting a lifting interval to drive the adjusting plate 5 to move up and down, not only can the guardrail posts be smoothly positioned between the first positioning plate 4 and the second positioning plate 6 when the adjusting plate 5 moves up, but also when the adjusting plate 5 moves down, it can be positioned between the guardrail posts so that the multiple guardrail posts can be separated.

[0035] In another technical solution, the driving unit includes a first rotary motor 16 mounted on the first bracket 3. Multiple sets of second gears 19 are connected sequentially to the output shaft of the first rotary motor 16. The multiple sets of second gears 19 are arranged in a one-to-one correspondence with multiple first gears 23. Each set of second gears 19 includes a positioning cylinder 17, a slide rod 18 slidably connected to the positioning cylinder 17 (both the positioning cylinder 17 and the slide rod 18 are perpendicular to the second gear 19), and a second gear 19 located at the end of the slide rod 18. The second gear 19 meshes with its corresponding first gear 23. The positioning cylinder 17, which is close to the first rotary motor 16, is connected to the first rotary motor 16. By adopting this technical solution, the present invention, through the setting of a first rotary motor 16, a positioning cylinder 17, a sliding rod 18, and a second gear 19, can adjust the distance between the adjusting plate 5 and the first positioning plate 4, between the adjusting plates 5 and 5, and between the adjusting plate 5 and the second positioning plate 6 in one direction, so as to be applicable to guardrail posts of different diameters. On the other hand, by setting the positioning cylinder 17 and the sliding rod 18, the distance between the two second gears 19 can be adjusted so that the second gears 19 can adapt to the change in the position of the first gear 23.

[0036] In another technical solution, a circular first baffle 20 is coaxially provided on the slide rod 18 near the second gear 19. An annular first slide rail is provided along the outer edge of the first baffle 20, and a first slider slides along the first slide rail. A circular second baffle 22 is coaxially provided on the first nut 21 near the first gear 23. An annular second slide rail is provided along the outer edge of the second baffle 22, and a second slider slides along the second slide rail. The first slider and the second slider are connected. Using this technical solution, the present invention, by setting the first baffle 20 and the second baffle 22, enables the second gear 19 to better adapt to changes in the position of the first gear 23, preventing the first gear 23 from disengaging from the second gear 19.

[0037] In another technical solution, the first support 3 is provided with a fixing plate 9, and the fixing plate 9 is provided with a long strip-shaped first opening 30; the fixing plate 9 is arranged in a direction perpendicular to the conveying direction of the conveyor.

[0038] Multiple drive rods 25 are slidably arranged within the first opening 30 (a fifth slide rail 33 is provided within the first opening 30, and a fifth slider 34 is provided on the drive rod 25, with the fifth slider 34 slidably connected to the fifth slide rail 33). One end of the drive rod 25 (the drive rod 25 is arranged along the length direction of the adjusting plate 5) is connected to the adjacent first nut 21 and first threaded rod 24, and the other end of the drive rod 25 is provided with a connecting plate 26. The adjusting plate 5 and the connecting plate 26 can be slidably connected up and down (a fourth slide rail 31 is provided on the connecting plate 26, and a fourth slider 32 is provided on the adjusting plate 5, with the fourth slide rail 31 and the fourth slider 32 slidably connected to realize that the adjusting plate 5 and the connecting plate 26 can be slidably connected up and down).

[0039] The conveyor is equipped with a second support 7, and the second support 7 is equipped with a first connecting rod 8. The first connecting rod 8 is equipped with two first telescopic motors 27, and the ends of the two first telescopic motors 27 are connected to a second connecting rod 28. The top of the adjusting plate 5 is equipped with a fixing ring 29, and the second connecting rod 28 passes through multiple connecting rings in sequence. Using this technical solution, the present invention, through the arrangement of the connecting plate 26, the fourth slide rail 31, the fourth slider 32, the drive rod 25, the first telescopic motors 27, and the fixing rings 29, not only satisfies the need for driving the adjusting plate 5 to move up and down, but also allows the adjusting plate 5 to move towards or away from the first positioning plate 4.

[0040] In another technical solution, the portion of the conveyor located between the transfer frame 12 and the adjusting mechanism is provided with a third support 10. The third support 10 is equipped with a vertically movable baffle plate 11 (the vertical movement of the baffle plate 11 is driven). During use, the baffle plate 11 first blocks multiple guardrail posts, ensuring a fixed number of guardrail posts are simultaneously positioned between the first positioning plate 4 and the second positioning plate 6. After the adjusting plate 5 separates the multiple guardrail posts, the baffle plate 11 moves upward, and finally, the guardrail posts enter the transfer frame 12. Using this technical solution, the present invention, by setting the baffle plate 11, restricts the movement of the guardrail posts to fix the number of guardrail posts, and the baffle plate 11 also facilitates the smooth entry of the guardrail posts onto the transfer frame 12.

[0041] In another technical solution, the transfer frame 12 is equipped with two rotatable rotating rods. These rods can rotate to be along the conveyor's conveying direction or perpendicular to it. When perpendicular to the conveyor's conveying direction, the distance between the ends of the two rotating rods is greater than the diameter of the smallest guardrail post in actual use. The transfer frame 12 is equipped with two fifth rotary motors, and the two rotating rods are respectively connected to the two fifth rotary motors. Using this technical solution, the present invention achieves the fixation of the guardrail posts on the transfer frame 12 by setting the rotating rods.

[0042] In another technical solution, multiple support rods 36 are spaced apart on the crossbar 35. The support rods 36 are perpendicular to the crossbar 35, and the multiple support rods 36 are respectively connected to the transfer frame 12 and multiple limiting plates 15. When the transfer frame 12 is located above the conveyor, the crossbar 35 is slightly lower than the conveyor or flush with the conveyor. This technical solution facilitates the smooth entry of the guardrail posts onto the transfer frame 12.

[0043] In another technical solution, a first support plate 13 is horizontally mounted on the transfer frame 12, and a limiting plate 15 is connected to the first support plate 13. Two second telescopic motors are mounted on the first support plate 13, and the ends of the two second telescopic motors share a second support plate 14. The second support plate 14 has a second opening, through which the limiting plate 15 passes. By adopting this technical solution, the present invention, through the setting of the first support plate 13 and the second support plate 14, enables the transfer frame 12 to be applicable to guardrail posts of different lengths, thereby expanding the application range of the transfer frame 12.
