And the two ends of the supporting member 602 are both provided with protrusions 608 extending outward along the width direction of the moving seat 7, the two push rods 601 respectively penetrate through the protrusions 608 at the two ends of the supporting member 602 and are fixedly connected with the supporting member 602, and the bottom end surfaces of the protrusions 608 are abutted against the upper end surface of the moving seat 7, so as to support the push rods 601 at the bottom. When the position of the scale breaking roller 10 deviates in the process of being placed into the bearing moving frame 6, the scale breaking roller 10 presses the push rod 601, the protrusion 608 supports the push rod 601, and the situation that the push rod 601 is broken due to the fact that the scale breaking roller 10 presses downwards is avoided.

Meanwhile, the movable seat 7 forms a bearing part for bearing the scale breaking roller 10 between the head end and the tail end. In this embodiment, as shown in fig. 2, the movable base 7 is provided with a receiving groove 701 for receiving the scale breaking roller 10 in the receiving portion. The supporting slot 701 is located below the push rods 601 in the vertical direction, and the supporting slot 701 is located between the two push rods 601 in the horizontal direction. In a preferred embodiment, the trough 701 is an arcuate trough that conforms to the surface of the scale breaking roll 10. When the scale breaking roller 10 is arranged on the bearing moving frame 6, the shaft cores at two ends of the scale breaking roller 10 are positioned in the U-shaped grooves 603 of the two U-shaped pieces, the outer roller wall of the scale breaking roller 10 is abutted against the bearing bracket 701 on the moving seat 7, and the scale breaking roller 10 is supported at the bottom through the bearing bracket 701. And a plurality of hollow parts 702 are arranged at the bottom of the bearing groove 701 along the length direction of the movable seat 7. The weight of the movable base 7 is reduced by providing a plurality of cutouts 702 to facilitate the feeding of the movable base 7.

And the upper end surface of the movable seat 7 is provided with fixed blocks 8 on the left and right sides of the head and tail ends, and the two push rods 601 respectively penetrate through the fixed blocks 8 on the left and right sides and can slide relative to the fixed blocks 8. The moving seat 7 is also provided with a roll changing driving component for driving the bearing moving frame 6 to move along the length direction of the moving seat 7. In this scheme, roll change drive assembly includes two cylinders 9, and the cylinder fixed mounting of two cylinders 9 is in the tail end of removing seat 7, and the piston rod on two cylinders 9 runs through respectively and removes the fixed block 8 of the 7 tail end left and right sides of seat and is connected with support piece 602 that closes on. The supporting member 602 is pushed by the cylinder 9 to move along the upper end surface of the moving seat 7, so as to drive the push rod 601 to move on the upper end surface of the moving seat 7.

In addition, two ends of the push rod 601 are further provided with second limiting members. When the cylinder 9 drives the bearing moving frame 6 to the stroke end, the second limiting block 605 abuts against the fixed block 8, so that the push rod 601 is prevented from being separated from the fixed block 8.

In this embodiment, the descaling unit of the descaling roll on the frame 11 can be referred to as a descaling roll changing work vehicle with the application number "201910947013.2" and a lifting wire descaling mechanism provided in the working method thereof, and the difference is that the bottom end surface of the frame 11 for mounting the upper beam of the descaling roll 10 is an inclined surface, so that the descaling roll 10 is inclined relative to the horizontal surface. The position relationship between the scale breaking roller 10 and the upper beam can be referred to the position relationship between the scale breaking roller and the upper beam in the steel wire derusting production line and the steel wire derusting mechanism in the derusting process of the application number '201910947037.8', so the specific structure of the scale breaking roller is not described in detail herein. When the scale breaking roller rust removing unit, namely the scale breaking roller 10 in the lifting steel wire rust removing mechanism, is worn and needs to be replaced, the base 4 travels to a preset position beside the rack 11 under the action of the transverse driving assembly and the lifting assembly 3, so that the moving seat 7 is just aligned to the inlet of the roller changing channel 1101, and the first guide rail 501 and the second guide rail 502 are positioned on the same straight line. At this time, the carrying moving frame 6 is in an idle state, and the cylinder 9 drives the carrying moving frame 6 to move from the head end of the moving seat 7 to the tail end of the moving seat 7 to the first roll changing position. The traveling mechanism 5 drives the movable base 7 to feed along the longitudinal direction of the first guide rail 501 and the second guide rail 502, and the movable base 7 slides into the roll changing channel 1101 and moves to the lower roll changing position of the descaling rolls 10. The lifting mechanism above the base of the scale breaking roller 10 drives the scale breaking roller 10 to descend until the scale breaking roller 10 is placed between the two push rods 601 of the bearing moving frame 6, and the shaft cores at the two ends of the scale breaking roller 10 are placed in the U-shaped grooves 603 of the two supporting members 602. Similarly, the specific lifting mechanism and the lifting process of the scale breaking roller 10 can be referred to a scale breaking roller changing operation vehicle and the operation method thereof with the application number "201910947013.2", and therefore, a description thereof will not be provided herein.

Subsequently, the bearing blocks at the relatively lower end of the scale breaking roll 10 are slid off the scale breaking roll 10. The scale breaking roller 10 is limited by the first limit block 604 on the U-shaped part. Then the cylinder 9 pushes the push rod 601 to drive the whole bearing moving frame 6 to move obliquely downwards along the moving seat 7, so as to drive the scale breaking roller 10 on the bearing moving frame 6 to move obliquely downwards, and the scale breaking roller 10 is separated from the bearing seat at the relatively higher end in a sliding manner, so that the roller unloading action is completed. The traveling mechanism 5 drives the movable seat 7 to retreat onto the base 4, and the base 4 retreats to the initial position under the action of the transverse driving component and the lifting component 3.

The worn scale breaking roller 10 is then removed from the carrier carriage 6 and replaced with a intact scale breaking roller 10. The base 4 is moved to the preset position beside the frame 11 again under the action of the transverse driving assembly and the lifting assembly 3, so that the moving seat 7 is just aligned with the inlet of the roll changing channel 1101. The traveling mechanism 5 drives the movable base 7 to move to the roll changing position again. The cylinder 9 drives the bearing movable seat 7 to move upwards along the upper end face of the movable seat 7 in an inclined mode, so that a mandrel at one end of the descaling roller 10 is inserted into a bearing seat at one end which is relatively higher. And finally, the bearing seat on the lower side of the scale breaking roller seat is reset in a sliding mode, and is locked with the mandrel at the other end of the scale breaking roller 10 to finish the action of the upper roller.

The scale breaking rolls 10 are arranged obliquely to the horizontal plane in order to brush the places where the wires cannot be brushed originally. Be the contained angle setting between up end through removing seat 7 and the horizontal plane in this scheme, and the head end that bears the weight of the up end of removing seat 7 and remove frame 6 is less than the tail end that bears the weight of and remove frame 6. The scale breaking roller 10 arranged in an inclined mode can directly fall onto the bearing moving frame 6, and the condition that the scale breaking roller 10 is driven to rotate to the horizontal plane through a bearing seat at one end of the scale breaking roller 10 driven by an oil cylinder and then roller unloading and roller loading actions are carried out is not needed. And in the whole roll changing action, only one bearing seat on the scale breaking roll seat is required to move, and the other bearing seat is not required to move, so that the structure is simpler, and the consumable materials of the moving mechanism are reduced.

And an elastic member is further disposed on the movable base 7, as shown in fig. 9, in this embodiment, the elastic member is a spring 606. The push rod 601 is fixedly provided with a stop 607, the spring 606 is sleeved on the push rod 601, and two ends of the spring 606 respectively abut against the stop 607 and the fixing block 8. When the roller-changing driving assembly drives the bearing movable frame 6 to move downwards along the movable seat 7, the stop 607 presses the spring 606 to compress along with the movement of the push rod 601. When the roller-changing driving assembly drives the bearing movable frame 6 to move upwards along the movable seat 7, the restoring force of the spring 606 cooperates with the roller-changing driving assembly to drive the bearing movable frame 6 to move. Part of the gravity is offset by the restoring force of the spring 606, so that the energy consumption of the feed driving assembly is reduced, and the power requirement on the feed driving assembly is reduced.

Certainly, when it is ensured that the roll changing driving assembly drives the bearing moving frame 6 to move upwards along the moving seat 7, the restoring force of the spring 606 can cooperate with the roll changing driving assembly to drive the bearing moving frame 6 to move, the stopper 607 can also be fixedly arranged on the moving seat 7, and two ends of the spring 606 respectively abut against the stopper 607 and the supporting member 602, which is also possible. And the two ends of the spring 606 are respectively connected with the stopper 607 and the fixed block 8, so that when the bearing moving frame 6 moves downwards along the moving seat 7, the spring 606 is in a stretching state.

Based on the scale breaking roller changing cart, the embodiment also provides a scale breaking roller changing method, which comprises the following steps:

s1, the bearing moving frame on the moving seat is in an unloaded state;

s4, placing a new scale breaking roller on the bearing moving frame;
