Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] As Figs. 1-2 shown, a tension leveler roller replacement device comprises a ground rail 1 installed on the ground, a support 2 is arranged above the ground rail 1, the support 2 is slidingly arranged on the ground rail 1 through a pulley, a lower roller replacement track 3 is arranged at the upper right part of the support 2, an upper roller replacement track 4 is arranged at the upper left part of the support 2, a supporting vehicle 5 is slidingly arranged on the upper roller replacement track 4, a mounting frame 6 is fixed on the supporting vehicle 5, a jacking assembly is arranged at the front part of the mounting frame 6, and a limiting assembly for limiting the jacking assembly is arranged in the mounting frame 6.

[0021] The support 2 is moved so that the lower roll replacement rail 3 on the support 2 is aligned with the lower roll group of the tension leveler, and then the lower roll group of the tension leveler is pulled out for replacement and maintenance;

[0022] First, the support 2 is moved so that the upper roll replacement rail 4 is moved directly below the upper roll group of the tension leveler, and then the support vehicle 5 is pushed so that the jacking assembly is located directly below the upper roll group of the tension leveler, and then the jacking assembly is lifted to hold the upper roll group of the tension leveler, and then the jacking assembly is limited by the limiting assembly to prevent the jacking assembly from falling, and then the support vehicle 5 is pulled to move the upper roll group of the tension leveler out for maintenance and replacement;

[0023] Thus, the upper roll group and the lower roll of the tension leveler can be quickly replaced.

[0024] In this embodiment, the height of the lower roll replacement rail 3 is flush with the bottom of the lower roll group of the tension leveler, so that the lower roll group of the tension leveler can be directly pulled out onto the lower roll replacement rail 3;

[0025] As a preferred, the jacking assembly comprises two fixed plates 7 fixed to the upper side of the support vehicle 5, a rocker plate 8 rotatably connected between the two fixed plates 7, a front end of the rocker plate 8 rotatably connected with the two fixed plates 7, a rocker rod 9 fixed to the front end of the rocker plate 8, a jacking column 10 slidingly connected to the front part of the mounting frame 6, the lower part of the jacking column 10 contacting the rear end of the rocker plate 8, the jacking column 10 penetrating the upper end of the mounting frame 6 and fixed with a jacking block 11 for supporting the upper roll group of the tension leveler, a jack plug 12 is formed in the middle part of the jacking column 10, and the limiting assembly is limited to the jacking column 10 through the jack plug 12;

[0026] The support 2 and the support vehicle 5 are pushed so that the jacking block 11 in the jacking assembly is located directly below the upper roll group of the tension leveler, and then the rocker rod 9 is pulled down, the rocker rod 9 drives the rocker plate 8 to rotate around the rotating connection shaft of the rocker plate 8 and the fixed plate 7, so that the rear end of the rocker plate 8 rises, the jacking column 10 is pushed up, the jacking column 10 drives the jacking block 11 to rise, the jacking block 11 pushes against the front part of the upper roll group of the tension leveler, and then the height of the jacking column 10 is limited by the limiting assembly, so that the jacking column 10 is fixed to this height and does not fall, and then the support vehicle 5 and the upper roll group of the tension leveler are pulled away from the tension leveler.

[0027] In this embodiment, the jacking block 11 is in the shape of a concave, which can make the upper roll group of the tension leveler located in the groove of the jacking block 11, and the placement is more stable.

[0028] In this embodiment, the limiting assembly comprises a plug rod 13 inserted into the upper part of the mounting frame 6, a driving groove 14 is formed in the front part of the mounting frame 6, a clamping block 15 is fixed in the middle part of the driving groove 14, and a push rod 16 is fixed to the left part of the plug rod 13;

[0029] When the jacking column 10 drags the front end of the upper roll group of the stretch leveler, the insertion hole 12 of the jacking column 10 is concentric with the insertion rod 13, at this time, the push rod 16 is pushed towards the jacking column 10, the push rod 16 drives the insertion rod 13 to move and is inserted into the insertion slot, thereby limiting the jacking column 10, the jacking column 10 cannot move up and down at this time, then the push rod 16 is rotated downward, the push rod 16 drives the insertion column to rotate, so that the left side wall of the push rod 16 is attached to the right side wall of the clamping block 15, at this time, the push rod 16 cannot move left and right, then the support vehicle 5 and the upper roll group of the stretch leveler can be pulled out to move out the upper roll group of the stretch leveler for maintenance and replacement;

[0030] The upper roll group of the stretch leveler which is maintained and replaced can push the support vehicle 5, so that the upper roll group of the stretch leveler is reset, then the push rod 16 is rotated first, so that the push rod 16 is located in the horizontal direction, at this time, the side wall of the push rod 16 no longer contacts the clamping block 15, at this time, the push rod 16 is moved away from the jacking column 10, the push rod 16 drives the insertion rod 13 to move, the insertion rod 13 gradually separates from the insertion hole 12, when the insertion rod 13 completely separates from the insertion hole 12, the jacking column 10 is released from the limitation, the jacking column 10 can move up and down, the jacking column 10 is lowered to drive the jacking block 11 to separate from the upper roll group of the stretch leveler, then the push rod 16 is rotated to be vertical, at this time, the right side wall of the push rod 16 is attached to the left side wall of the clamping block 15, the push rod 16 cannot move left and right, and the support vehicle 5 can be pulled out.

[0031] In the embodiment, the front part of the lower roll replacement track 3 is fixed with a limiting block 17, the limiting block 17 can limit the farthest distance of the movement of the lower roll group of the stretch leveler, and prevent the lower roll group of the stretch leveler from separating from the stretch leveler.

[0032] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
