[0002] Pickling is a process in which the steel structure is placed in an acidic solution and the oxides and rust on the surface of the steel structure are cleaned with the acidic solution. It is also one of the main methods for treating steel structures. The entire pickling process is generally carried out in conjunction with an entire assembly line. During the cleaning process, multiple pairs of conveyor rollers are required to transport the steel structure. The conveyor rollers will also be corroded if they are in contact with the acidic solution for a long time. Therefore, the rollers need to be replaced regularly to ensure their service life.

[0003] Currently, replacement is basically done manually, by removing the connection points at both ends of the roller, then sending the roller away by lifting equipment or manually, and then putting the new roller on. This process is rather cumbersome, because the current hoisting can only lift one at a time, and the old roller needs to be put down before the new roller can be lifted for installation. For this purpose, a roller replacement device is set up. Utility Model Content

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-3The utility model discloses a pickling line roller changing device, comprising a base 1, three rollers 2 are evenly fixedly connected to the bottom side wall of the base 1, a reinforcing conical seat 3 is fixedly connected to the middle of the top side wall of the base 1, a column 4 is fixedly connected to the top of the reinforcing conical seat 3 away from the base 1, and a rotating column 5 is rotatably connected to one end of the column 4 away from the reinforcing conical seat 3, and a cross beam 6 is fixedly connected to both side walls of the rotating column 5 near the top edge, and two connecting plates 9 are set on the bottom side wall of each cross beam 6, and a clamp 10 is fixedly connected to the bottom side wall of the connecting plate 9, and a vertical column 7 is fixedly connected to the middle of the top side wall of the rotating column 5 away from the column 4, and a reinforcing zipper 8 is fixedly connected to the side wall opposite to the cross beam 6 and close to the top edge, and the reinforcing zipper 8 is fixedly connected to the top side wall of the cross beam 6 through its end away from the vertical column 7;

[0014] A double-headed motor 12 is detachably embedded in the middle of the bottom side wall of the beam 6, and movable grooves 13 are provided at the bottom of the beam 6 and on both sides of the double-headed motor 12. A threaded rod 14 is rotatably connected in each movable groove 13, and the output end of the double-headed motor 12 extends into the movable groove 13 and is fixedly connected to one end of the threaded rod 14. A movable block 15 is engaged and sleeved on the threaded rod 14, and the bottom end of the movable block 15 is detachably connected to a telescopic rod 16, and the output end of the telescopic rod 16 is detachably connected to the top of the connecting plate 9, and the edges on both sides of the opening of the clamp 10 are fixedly connected to fixed plates 11, and the two fixed plates 11 are fixed by screws.

[0015] The preferred technical effect of this scheme is to move the base 1 to the specified position through the roller 2, and then start the corresponding telescopic rod 16 to lower the connecting plate 9, and start the double-headed motor 12 to rotate the threaded rod 14 to adjust the distance between the two connecting plates 9 according to the length of the roller in advance. After the connecting plate 9 is lowered to the specified position, the fixed plate 11 is clamped on the roller, and the screws connected to the fixed plate 11 are used to threadably fix it, so that the roller is stably connected to the clamp 10, and then the clamp 10 is started to lift the removed old roller, and then the rotating column 5 is rotated to move the pre-lifted new roller to the installation point, and the new roller is lowered through the clamp 10 and then the staff connects and fixes it. The whole process does not need to repeat the lifting action and can be completed in one go, thereby improving the efficiency of roller replacement.

[0016] A rotation groove 18 is provided in the middle of the side wall opposite to the column 4 and the rotating column 5, and a rotating column 17 is rotatably connected in the rotation groove 18. The rotating column 17 is fixedly connected in the middle of the side wall opposite to the rotating column 5 and the column 4. Six support columns 19 are evenly fixedly connected to the side wall opposite to the column 4 and the rotating column 5 and close to the rotation groove 18. A ball 20 is rotatably connected to the top of each support column 19, and the ball 20 contacts the bottom side wall of the rotating column 5. An annular groove is provided on the side wall of the rotation groove 18, and a protrusion is fixedly connected to the side wall corresponding to the rotating column 17 and the groove, and the protrusion is rotatably connected in the groove.

[0017] The preferred technical effect of this solution is that, in order to ensure the smooth rotation of the rotating column 5, a groove is set in the rotating groove 18 and a protrusion is fixed on the outer wall of the rotating column 17. The cooperation of the two can ensure the stability of the rotating column 17 and prevent it from tilting during the rotation process, thereby affecting the stability of the two cross beams 6. The set support column 19 and ball 20 can support the surrounding model of the rotating column 5. Because the weight will change during the lifting process, in order to avoid safety accidents caused by weight changes, the support column 19 is set to provide auxiliary support for the rotating column 5 to ensure the stability of the rotating column 5 during the rotation process. At the same time, the set ball 20 can not only make the rotation and replacement of the rotating column 5 smooth, but also reduce the wear on the rotating column 5.

[0018] Specifically, when the utility model is used, the new roller to be installed is pre-installed under one of the crossbeams 6, and then the equipment is moved to the specified position by the roller 2, and then the telescopic rod 16 is started to lower the corresponding connecting plate 9 and the clamp 10, and then the clamp 10 is connected to the old roller, and then the staff disassembles the old roller, and then lifts the old roller by the telescopic rod 16 after disassembly, and then rotates the rotating column 5 to move the new roller to the installation point and lower it by the telescopic rod 16, and then the staff installs the new roller at the corresponding position to realize the replacement of the roller. The whole process is completed in one go, which effectively improves the effect of replacement, and the process does not require the staff to move the roller, reducing the workload of the staff;

[0019] To ensure safety, the roller 2 can be selected with a brake structure, which can ensure that the base 1 is fixed after it is moved to the specified position, and avoid the shaking of the base 1 due to the instability of the roller 2, thereby affecting the replacement of the rollers. The two cross beams 6 are set at a right angle to ensure that one side of the base 1 is always in a horizontal state, mainly to ensure that one side of the base 1 is always parallel to the side where pedestrians walk, to avoid the parts of the base 1 extending into the walking surface of the staff and causing safety hazards. At the same time, the telescopic rod 16 is used to control the lifting of the connecting plate 9, which can avoid the shaking caused by the traditional motor and iron cable combination, thereby preventing the shaking parts from causing harm to the staff.
