In this embodiment, the phosphorus breaking roller rust removing unit on the frame 11 may refer to a phosphorus breaking roller changing work vehicle with application number "201910947013.2" and a lifting steel wire rust removing mechanism provided in the working method thereof, and the difference is that in this embodiment, the bottom end surface of the frame 11 for mounting the upper beam of the phosphorus breaking roller 10 is an inclined surface, so that the phosphorus breaking roller 10 is inclined relative to the horizontal surface. The position relationship between the phosphorus breaking roller 10 and the upper beam can be referred to the position relationship between the phosphorus breaking roller and the upper beam in the steel wire rust removing production line and the steel wire rust removing mechanism in the rust removing process of application number 201910947037.8, so the specific structure of the phosphorus breaking roller is not described in detail herein. When the phosphorus-breaking roller rust removing unit, namely the phosphorus-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 roller changing channel 1101 and moves to the lower roller changing position of the phosphorus crushing roller 10. The lifting mechanism above the seat of the phosphorus breaking roller 10 drives the phosphorus breaking roller 10 to descend until the phosphorus 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 phosphorus breaking roller 10 are placed in the U-shaped grooves 603 of the two supporting pieces 602. Similarly, the specific lifting structure of the lifting mechanism and the lifting process of the phosphorus crushing roller 10 can be referred to a phosphorus crushing roller changing operation vehicle and the working method thereof with the application number "201910947013.2", so that the description thereof will not be made herein too much

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;

s2, moving the base to a preset position beside the frame with the roller changing channel inside, wherein the moving seat of the idle bearing moving frame just aligns with the inlet of the roller changing channel, and slides into the roller changing channel under the driving of the traveling mechanism;

s3, the old scale breaking roller falls onto the bearing moving frame, the bearing seat on the lower side of the scale breaking roller seat slides to be separated from the shaft head of one end of the scale breaking roller, the roller changing driving assembly on the moving seat drives the bearing moving frame to move downwards along the moving seat in an inclined mode to drive the shaft head of the other end of the old scale breaking roller to be separated from the bearing seat on the upper side of the scale breaking roller seat, and then the moving seat moves reversely to exit the rack for unloading;

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

s5, repeating the action of S2 until the movable seat slides into the roller changing channel;

s6, driving the bearing moving frame to move upwards along the moving seat in an inclined manner by the roller changing driving assembly on the moving seat to drive the shaft head of a new scale breaking roller to be inserted into the bearing seat on the higher side of the scale breaking roller seat, enabling the bearing seat on the lower side of the scale breaking roller seat to slide and be buckled with the shaft head on the other end of the scale breaking roller to finish the action of upper roller, and enabling the moving seat to move reversely to exit the derusting rack; the base retreats to the initial position under the action of the lifting assembly and the transverse driving assembly.
