Description

Technical Field

[0001] This invention relates to a method for removing double flat and vertical rollers. Background Technology

[0002] On a section steel rolling production line, 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 on a section steel rolling mill can be done using a roll-changing robot, manual replacement of vertical rolls is time-consuming and labor-intensive. Currently, there is no precedent for simultaneously replacing both horizontal and vertical rolls. Summary of the Invention

[0003] To address this problem, this invention proposes a method for simultaneously replacing two flat and vertical rollers.

[0004] To achieve the above objectives, the present invention provides a method for the double removal of horizontal and vertical rollers, comprising a track, a support frame trolley, a vertical roller arch slide rail, 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 fixing hydraulic cylinder, locking bolts, a first intermediate swing shaft hydraulic cylinder, a first base, a second intermediate swing shaft hydraulic cylinder, a second base, a longitudinal moving body, a high-rigidity roller frame, and a third intermediate swing shaft hydraulic cylinder. Two sets of tracks are symmetrically arranged along the centerline of the second base, and the tracks are fixed to the civil engineering foundation. The method includes the following steps:

[0005] The first step involves fully retracting the piston rod of the intermediate swing shaft hydraulic cylinder three, causing the two sets of high-rigidity roll storage racks fixed on the longitudinal moving car body to stop at positions E and F respectively. At position E, the high-rigidity storage rack is empty. Then, using the mill crane's hoisting tools, the mill body assembly to be replaced, removed from the production line, is transported to position F. Next, the new roll is hoisted to the high-rigidity storage rack at position E. At this time, the piston rod of the intermediate swing shaft hydraulic cylinder one is fully retracted, the support frame trolley is at position 1, the piston rod of the intermediate swing shaft hydraulic cylinder two is fully extended, and the horizontal roll arch locking car body is at position A. For the rolls, the old roll is at position F, which is the same position as the horizontal roll arch locking car body at position A.

[0006] The second step is to fully extend the piston rod of the hydraulic cylinder of the middle swing shaft, move the support frame trolley from position 1 to position 2, and then lock the horizontal roller arch to the horizontal roller arch locking trolley body by locking bolts. The vertical roller arch is locked to the horizontal roller arch by hydraulic bolts. The vertical roller arch and the vertical roller box are connected together by tie rods.

[0007] The third step is to retract the piston rod of the hydraulic cylinder of the middle swing shaft, so that the horizontal roller arch locking car body moves from position A to position B. At this time, the piston rod of the tail fixing hydraulic cylinder fixed on the horizontal roller arch locking car body is in the fully retracted state. At this time, the lifting platform is in position C, and the piston rod of the hydraulic cylinder of the vertical roller arch swing shaft is in the maximum extended position. The vertical roller arch and the vertical roller box are in position 3.

[0008] Fourth step, the piston rod of the drive pin cylinder extends fully, and the piston rod drives the clamping plate to move upward, locking the vertical roller arch. At this time, the vertical roller arch and the vertical roller box are still in position 3.

[0009] Fifth 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 4. At this time, the lifting platform is still in position C.

[0010] Step 6: Extend the piston rod of the hydraulic cylinder at the tail end to make the lifting platform move upward until the lifting platform is at position D. Due to the structural characteristics of the lifting platform, the vertical roller box is locked by the groove surface of the lifting platform. At this time, the vertical roller arch and the vertical roller box are still at position 4.

[0011] Step 7: 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. The clamping plate connected to the drive plate drives the vertical roller arch to move to the left, gradually disengaging from the vertical roller box, so that the vertical roller arch moves to position 5. At this time, the lifting platform is still in position D.

[0012] Step 8: The old vertical roller box located at position 4 is lifted away by a hoisting tool, and the new vertical roller box is hoisted to position 4 to prepare for the next step of resetting the left side. At this point, the dismantling of the vertical roller is completed.

[0013] Step 9: The piston rod of the hydraulic cylinder 3 driving the intermediate swing shaft extends fully, causing the roll on the high-rigidity storage rack at position E to move to position F, and at the same time the old roll on the high-rigidity storage rack at position F to move to position G.

[0014] Step 10: Reverse steps 8, 7, 6, 5, 4, 3, 2, and 1 to complete the reassembly of the flat and vertical rollers. This completes the replacement process of the old and new vertical roller boxes.

[0015] Furthermore, the support frame trolley is arranged on two sets of tracks.

[0016] Furthermore, the vertical roller archway slide is arranged on the upper part of the support frame trolley, with two sets arranged.

[0017] 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.

[0018] 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.

[0019] Furthermore, the piston rod of the first intermediate swing shaft hydraulic cylinder is hinged to the support frame trolley, and the intermediate swing shaft of the first intermediate swing shaft hydraulic cylinder is hinged to the base, which is fixed on the civil engineering foundation.

[0020] Furthermore, the horizontal roller arch locking car body can move freely horizontally on the base along the second transverse center line of the base. 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.

[0021] Furthermore, two locking bolts are hinged to each side of the horizontal roller arch locking car body.

[0022] Furthermore, the piston rod of the second intermediate swing shaft hydraulic cylinder is hinged to the lower part of the horizontal roller arch locking car body, and the intermediate swing shaft of the second intermediate swing shaft hydraulic cylinder is hinged to the second base, which is fixed on the civil engineering foundation.

[0023] Furthermore, two sets of high-rigidity roll frames are arranged along the longitudinal center line of the second base, and are respectively fixed on the longitudinal moving car body. The longitudinal moving car body can move freely back and forth along the longitudinal center line of the second base. The piston rod of the third intermediate swing shaft hydraulic cylinder is hinged to the lower part of the longitudinal moving car body, and the intermediate swing shaft of the third intermediate swing shaft hydraulic cylinder is hinged to the second base.

[0024] This invention not only effectively solves the problem of simultaneously replacing horizontal and vertical roller boxes, but also offers high efficiency, stable structure, and simple and convenient equipment maintenance. Attached Figure Description

Then, 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. 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, so that the vertical roller arch and the vertical roller box move to position 4. At this time, the lifting platform 10 is still in position C.

At this point, the removal of the vertical roll is complete. Step 9: The piston rod of the hydraulic cylinder (III) 19 driving the intermediate swing shaft is fully extended, causing the roll on the high-rigidity storage rack at position E to move to position F, while the old roll on the high-rigidity storage rack at position F moves to position G.
