[0024] Example
[0025] like Figure 6 As shown, Figure 6 This is a structural diagram of the roller 5 on the welded pipe production line. The roller 5 is similar to a dumbbell in appearance, thick at both ends and thin in the middle, with a through hole in the middle. The roller 5 is installed on the roller shaft 6. When inspecting or processing welded pipes of different sizes, the roller 5 originally installed on the roller shaft 6 needs to be disassembled and replaced. Since the roller 5 is heavy and has a smooth surface, it is time-consuming and labor-intensive to replace it by manpower, and it is easy to slip and cause safety accidents.
[0026] like Figure 1-Figure 5As shown, a tooling for safely and quickly replacing a roll is mainly composed of a counterweight rod 1, a connecting plate 2, a lifting ring 3, a roll support rod 4, and a limit adjustment mechanism 8. The lifting ring 3 is fixedly connected to the top of the connecting plate 2, the counterweight rod 1 and the roll support rod 4 are fixedly connected to the left and right sides of the connecting plate 2, the inner diameter of the roll support rod 4 is slightly larger than the outer diameter of the roll shaft 6 so as to be plugged into the roll shaft 6, and the limit adjustment mechanism 8 is installed on the right side of the roll support rod 4. The limit adjustment mechanism 8 is used to limit the roll when lifting the roll 5 to prevent the roll 5 from In case of a falling accident, the roller 5 is inserted into the roller support rod 4 during lifting, and the limit adjustment mechanism 8 is adjusted to extend the roller support rod 4 to limit the roller 5. After the old roller is dismantled, the roller support rod 4 is connected to the end of the roller shaft 6, and the limit adjustment mechanism 8 is adjusted to extend into the roller support rod 4 to release the limit, and the roller 5 is pushed onto the roller shaft 6. By using this tooling, a transition section is formed between the tooling and the roller shaft 6, so that fast and labor-saving assembly can be achieved. Compared with the traditional manual replacement of rollers, it effectively saves manpower and is safer.
[0027] In some optional embodiments, the limit adjustment mechanism 8 is composed of an upper screw 10, a lower screw 11, a threaded sleeve 12, and a gear 16. The upper screw 10 and the lower screw 11 are threadedly connected to the threaded sleeve 12, and the gear 16 is fixedly connected to the outside of the threaded sleeve 12. When the gear 16 rotates, it drives the threaded sleeve 12 to rotate, thereby driving the upper screw 10 and the lower screw 11 to rise and fall relative to the threaded sleeve 12.
[0028] In some optional embodiments, the threads on the upper screw 10 and the lower screw 11 are in opposite directions. When the threaded sleeve 12 rotates, the upper screw 10 and the lower screw 11 move in opposite directions, thereby achieving the simultaneous extension or extension of the upper screw 10 and the lower screw 11 relative to the roller support rod 4.
[0029] In some optional embodiments, a tooth plate 9 is slidably connected to the connecting plate 2, and the tooth plate 9 penetrates the connecting plate 2 and extends into the interior of the roller support rod 4 and is meshed and connected with the gear 16. The rotation of the gear 16 is controlled by the tooth plate 9. Preferably, as Figure 2 As shown, a handle is fixedly connected to the left side of the tooth plate 9 to facilitate operation.
[0030] In some optional embodiments, the top and bottom of the roller support rod 4 are provided with adjustment holes 7, the adjustment through hole 7 is fixedly connected to a limiting sleeve 17, the inner wall of the limiting sleeve 17 is fixedly connected to a limiting block 19, and the top of the upper screw 10 and the bottom of the lower screw 11 are provided with limiting grooves 15 matching the limiting blocks 19. The limiting grooves 15 and the limiting blocks 19 are used to limit the upper screw 10 and the lower screw 11 to ensure that the upper screw 10 and the lower screw 11 rotate relative to the threaded sleeve 12, thereby realizing the up and down movement of the upper screw 10 and the lower screw 11.
[0031] In some optional embodiments, ear plates 18 are fixedly connected to both left and right ends of the limiting sleeve 17 , and grooves 20 matching the ear plates 18 are formed on the left and right sides of the through hole 7 .
[0032] In some optional embodiments, the ear plate 18 is fixedly mounted on the groove 20 by bolts.
[0033] When installing the limit adjustment mechanism 8, firstly thread the upper screw 10 and the lower screw 11 onto the threaded sleeve 12, place the limit adjustment mechanism 8 into the roller support rod 4 through the adjustment hole 7, install the limit block 19 on the limit sleeve 17 onto the limit groove 15 of the upper screw 10 and the lower screw 11, place the ear plate 18 into the groove 20, and complete the installation by tightening with bolts.
[0034] When replacing the roll, first dismantle the old roll, install the roll to be installed on the roll support rod 4, adjust the upper screw 10 and the lower screw 11 through the tooth plate 9 to extend out of the roll support rod 4 for limiting, lift the whole to the vicinity of the roll shaft 6 through the lifting ring 3, adjust the position of the roll support rod 4 through the counterweight rod 1, and connect the roll support rod 4 to the end of the roll shaft 6, adjust the upper screw 10 and the lower screw 11 through the tooth plate 9 to extend into the roll support rod 4 to release the limit, and push the roll 5 onto the roll shaft 6. By using this tooling, a transition section is formed between the tooling and the roll shaft 6, so as to realize fast and labor-saving assembly. Compared with the traditional manual replacement of rolls, it effectively saves manpower and is safer.
