Description

Technical Field

[0001] This invention relates to a method for removing and replacing the locking mechanism of a vertical roller. Background Technology

[0002] In section steel rolling production lines, section steel rolling mills have vertical rolls compared to bar rolling mills. After a period of rolling, both horizontal and vertical rolls wear down, typically requiring replacement. While horizontal roll replacement in section steel rolling mills can be done using a roll-changing robot, manual replacement of vertical rolls is time-consuming and labor-intensive. Currently, there is no reliable equipment available for the dismantling, locking, and replacement of vertical rolls. Summary of the Invention

[0003] To address this problem, this invention proposes a method for removing and replacing vertical rollers, which can realize the removal, locking, and replacement of vertical rollers.

[0004] To achieve the above objectives, the present invention provides a method for removing and replacing the locking mechanism of a vertical roller, comprising a track, a support frame trolley, a vertical roller arch slide rail 3, a vertical roller arch swing shaft hydraulic cylinder, a support, a drive plate, a clamping plate, a pin hydraulic cylinder, a horizontal roller arch locking body, a lifting platform, a tail-end fixing hydraulic cylinder, and locking bolts; the track is symmetrically arranged in two sets along the center line of the base, and the track is fixed on the civil engineering foundation; the method for removing and replacing the locking mechanism includes the following steps:

[0005] First, extend the piston rod of the hydraulic cylinder that drives the intermediate swing shaft to extend, positioning the horizontal roller arch locking body at position A. Secure the horizontal roller arch to the horizontal roller arch locking body using two locking bolts. Lock the vertical roller arch to the horizontal roller arch using hydraulic bolts. The vertical roller arch and the vertical roller box are connected together by a tie rod. Next, retract the hydraulic cylinder that drives the intermediate swing shaft to retract, positioning the horizontal roller arch locking body at position B. At this point, the piston rod of the tail-fixed hydraulic cylinder fixed to the horizontal roller arch locking body is fully retracted, and the lifting platform is at position C. The piston rod of the hydraulic cylinder for the vertical roller arch swing shaft is at its maximum extension position, and the vertical roller arch and the vertical roller box are at position 1.

[0006] The second step is to drive the piston rod of the hydraulic cylinder to move upward, so that the clamping plate clamps the vertical roller arch. At this time, the vertical roller arch and the vertical roller box are still in position 1.

[0007] Third step, loosen the hydraulic bolts that fix the vertical roller arch. At this time, the vertical roller arch and the vertical roller box can be separated from the horizontal roller arch as a whole. Then drive the piston rod of the hydraulic cylinder of the vertical roller arch swing shaft to move to the left. The piston rod drives the drive plate to move to the left. The clamping plate connected to the drive plate drives the vertical roller arch and the vertical roller box to move to the left, so that the vertical roller arch and the vertical roller box move to position 2.

[0008] The fourth step is to extend the piston rod of the hydraulic cylinder at the tail end, causing the lifting platform to move upward until it is in position D. Due to the structural characteristics of the lifting platform, the vertical roller box is locked in place by the groove surface of the lifting platform. At this time, the vertical roller arch and the vertical roller box are still in position 2.

[0009] Fifth step, loosen the connecting rod between the vertical roller arch and the vertical roller box, and continue to drive the piston rod of the hydraulic cylinder of the vertical roller arch swing shaft to move to the left. The piston rod drives the drive plate to move to the left, and the clamping plate connected to the drive plate drives the vertical roller arch to move to the left, so that the vertical roller arch moves to position 3, and the vertical roller arch and the vertical roller box separate. At this time, the vertical roller box is still in position 2. Then, the old vertical roller box is removed and lifted away by hoisting tools.

[0010] Step 6: Hoist the new vertical roller box into its original position, i.e., position 2;

[0011] Step 7: Reverse Step 6, Reverse Step 5, Reverse Step 4, Reverse Step 3, Reverse Step 2, Reverse Step 1; This completes the entire process of replacing the old and new vertical roller boxes.

[0012] Furthermore, the support frame trolley is arranged on two sets of tracks.

[0013] Furthermore, the vertical roller archway slide is arranged on the upper part of the support frame trolley, with two sets arranged.

[0014] Furthermore, the piston rod of the hydraulic cylinder of the vertical roller arch swing shaft is hinged to the lower part of the drive plate, the swing shaft of the hydraulic cylinder of the vertical roller arch swing shaft is hinged to the support, the support is fixed on the support frame trolley, and the two sides of the drive plate can slide freely in the vertical roller arch slide.

[0015] Furthermore, the piston rod of the pin hydraulic cylinder is fixed below the clamping plate, and the cylinder body is fixed below the drive plate, so that the pin hydraulic cylinder can drive the clamping plate to move up and down.

[0016] Furthermore, the horizontal roller arch locking car body can move freely horizontally on the base, and the tail-fixed hydraulic cylinder is fixed on the horizontal roller arch locking car body. One end of the piston rod of the tail-fixed hydraulic cylinder is fixed to the lower part of the lifting platform. The lifting platform forms a moving pair that can move up and down with the four circular guide grooves located on the horizontal roller arch locking car body through four columns, and can slide freely.

[0017] Furthermore, two locking bolts are hinged to each side of the horizontal roller arch locking car body.

[0018] Furthermore, the piston rod of the intermediate swing shaft lateral movement hydraulic cylinder is hinged to the lower part of the horizontal roller arch locking car body, and the intermediate swing shaft of the intermediate swing shaft hydraulic cylinder is hinged to the base. The base is fixed on the civil engineering foundation.

[0019] This invention not only effectively solves the problem of vertical roller box replacement, but also offers high efficiency, stable structure, and simple and convenient equipment maintenance. Attached Figure Description

[0040] Example 6

[0041] Based on the above embodiments, the piston rod of the pin hydraulic cylinder 8 is fixed below the clamping plate 7, and the cylinder body is fixed below the drive plate 6. The pin hydraulic cylinder 8 can drive the clamping plate 7 to move up and down.

[0042] Example 7

[0043] Based on the above embodiments, the horizontal roller arch locking car body 9 can move freely horizontally on the base, the tail fixing hydraulic cylinder 10 is fixed on the horizontal roller arch locking car body 9, one end of the piston rod of the tail fixing hydraulic cylinder 11 is fixed to the lower part of the lifting platform 10, and the lifting platform 10 forms a moving pair that can move up and down with the four circular guide grooves located on the horizontal roller arch locking car body 9 through four columns, and can slide freely.

[0044] Example 8

[0045] Based on the above embodiments, the locking, removal, and replacement process is as follows: First, the piston rod of the hydraulic cylinder for the lateral movement of the intermediate swing shaft extends, positioning the horizontal roller arch locking body 9 at position A (at this time, the horizontal roller arch is in the roll changing preparation state). The horizontal roller arch is locked to the horizontal roller arch locking body 9 by two locking bolts 12. The vertical roller arch is locked to the horizontal roller arch by hydraulic bolts (not shown in the figure). The vertical roller arch and the vertical roller box are connected together by a tie rod (not shown in the figure). The hydraulic cylinder for the lateral movement of the intermediate swing shaft retracts, positioning the horizontal roller arch locking body 9 at position B. At this time, the piston rod of the tail fixing hydraulic cylinder 11 fixed to the horizontal roller arch locking body 9 is fully retracted, the lifting platform 10 is at position C, and the piston rod of the hydraulic cylinder 4 of the vertical roller arch swing shaft is at its maximum extension position. The vertical roller arch and the vertical roller box are at position 1. The second step involves driving the piston rod of the hydraulic cylinder 8 to move upwards, causing the clamping plate 7 to engage the vertical roller arch. At this point, the vertical roller arch and the vertical roller box remain in position 1. The third step involves loosening the hydraulic bolts securing the vertical roller arch (not shown in the diagram). At this point, the vertical roller arch and the vertical roller box can detach from the horizontal roller arch as a single unit. Then, the piston rod of the hydraulic cylinder 4, which is driving the swing shaft of the vertical roller arch, moves to the left. The piston rod drives the drive plate 6 to move to the left, and the clamping plate 7 connected to the drive plate 6 drives the vertical roller arch and the vertical roller box to move to the left, bringing them to position 2. The fourth step involves extending the piston rod of the hydraulic cylinder 11 at the tail end, causing the lifting platform 10 to move upwards until it reaches position D. Due to the structural characteristics of the lifting platform, the vertical roller box is secured by the grooved surface of the lifting platform. At this point, the vertical roller arch and the vertical roller box remain in position 2. Step 5: Loosen the connecting rod between the vertical roller arch and the vertical roller box (not shown in the diagram). Continue to drive the piston rod of the hydraulic cylinder 4 of the vertical roller arch swing shaft to move to the left. The piston rod drives the drive plate 6 to move to the left, and the clamping plate 7 connected to the drive plate 6 drives the vertical roller arch to move to the left, so that the vertical roller arch moves to position 3, and the vertical roller arch and the vertical roller box separate. At this time, the vertical roller box is still in position 2. Then, the old vertical roller box is removed and lifted away by a hoisting tool. Step 6: Hoist the new vertical roller box into place in its original position, i.e., position 2. Step 7: Reverse step 6, reverse step 5, reverse step 4, reverse step 3, reverse step 2, and reverse step 1. At this point, the entire process of replacing the old and new vertical roller boxes is completed.
