Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of roller replacement for a leveling machine, and particularly relates to a single roller replacement device for an upper roller monotonous leveling machine. Background Art
[0002] The upper roller system of the integral beam leveler is a whole. When one of the upper working rollers is scratched or damaged and needs to be replaced, all the upper working rollers in the upper roller system of the leveler need to be removed from the inside of the equipment, disassembled, maintained, and then reassembled. The operation is poorly targeted and increases ineffective labor. The position of each upper working roller of the upper roller monotonic leveler can be adjusted individually. Compared with the integral beam leveler, there are more roller gap forms and better plate leveling effect. It can remove the scratched and damaged upper working rollers separately for maintenance; other undamaged upper working rollers do not need to be disassembled, which is highly targeted and has high labor efficiency. At present, there is no special replacement device for upper working rollers to replace single rollers of upper roller monotonic levelers. Utility Model Content

[0005] A single-roll replacement device for an upper-roll monotonic leveling machine comprises a frame, a lower working roll is mounted on the frame, an upper working roll mounted on the frame through an upper roll bearing seat is arranged above the lower working roll, and the device is characterized in that a roll-changing plate is arranged above the lower working roll, a roll-changing trolley is arranged above the roll-changing plate, a roll-changing frame body is overlapped on the outer side of the roll-changing plate, the roll-changing trolley consists of a wheel train and a car body mounted on the wheel train, and an arc groove is opened on the car body for placing the upper working roll.
[0006] The two sides of the upper roller bearing seat are integrally connected to the upper roller bearing seat shoulders.
[0007] Anti-rotation blocks are respectively installed on both sides of the end surface of the vehicle body head, and set screws are installed in the vertical direction of the anti-rotation blocks, and locking nuts are installed on the set screws.
[0008] The roller changing flat plate is overlapped in the docking groove of the roller changing frame.
[0009] The roll-changing trolley is connected with a hand-held pull rod on one side close to the roll-changing frame.
[0010] The wheel system comprises a wheel, the wheel is mounted on an axle through a bearing, the axle is mounted on a vehicle body, and the wheel and the axle are positioned with each other through a hole retaining spring, an axle retaining spring, a pressure cover and a spacer.
[0011] The beneficial effects of the utility model are: it is arranged between the upper and lower roller systems, and the disassembled upper working roller and the bearing seats at both ends are moved out of the roller system by rolling the wheel system. It can be performed on a single upper working roller, and has strong pertinence. The roller replacement process does not require the disassembly of the entire machine frame, and the workload is small.

DETAILED DESCRIPTION
[0019] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a roll-changing trolley 6, a roll-changing flat plate 5, a roll-changing frame 7, and a hand-held pull rod 16. The roll-changing flat plate 5 is a flat steel plate, which is placed on the lower working roll 2 in advance during the roll-changing process, and an internal roll-changing platform is formed on the lower working roll 2 for placing the roll-changing trolley 6. The roll-changing trolley 6 is arranged in two or more groups (at least two groups) according to the length of the upper working roll 4. The shape of the body 9 of the roll-changing trolley 6 matches the shape of the upper working roll 4, and is used to place the disassembled upper working roll 4. Four sets of wheel trains 8 are installed on each roll-changing trolley 6 to facilitate the transfer of the upper working roll 4. The roll-changing trolley 6 is provided with an anti-rotation device for the upper roll bearing seat 3 of the upper working roll 4 to prevent the upper roll bearing seat 3 from tipping over during the removal of the upper working roll 4. The roll changing frame 7 is a frame temporarily placed on the side of the roll system during the replacement of the upper working roll 4. The upper surface height of the roll changing frame 7 is flush with the upper surface of the roll changing plate 5, which is used to facilitate the upper working roll 4 to be removed from the inside of the equipment as a whole. A docking groove 15 is processed at the joint between the roll changing frame 7 and the roll changing plate 5. Placing the roll changing plate 5 into the docking groove 15 of the roll changing frame 7 can ensure that the connection transition position is flat, avoid the uneven and discontinuous roll changing plane caused by the deflection and sagging of the roll changing plate 5, and avoid affecting the roll changing action. The hand-held pull rod 16 can be installed on the roll changing trolley 6 to facilitate the manual pulling out of the roll changing trolley 6 during the roll changing process.
[0020] The upper part of the body 9 is an arc groove 10 for placing the upper working roll 4. The shape of the groove body matches the shape of the upper working roll 4 roller body, and is used to place the upper working roll 4 removed from the equipment. Two holes for installing the wheel train 8 are processed on both sides of the body 9, and four wheel trains 8 are installed to move out the roll-changing trolley 6. The head of the body 9 is equipped with an anti-rotation device to fix the upper roll bearing seat 3 installed on the upper working roll 4 to prevent the upper roll bearing seat 3 from tipping over. The body 9 is processed with a hole for installing the hand-held pull rod 16, which is used to connect with the hand-held pull rod 16.
[0021] One end of the axle 19 is threaded and mounted on the thread hole at the corresponding position of the vehicle body 9. The wheel 17 is mounted on the axle 19 through the bearing 18. The wheel 17 and the axle 19 are positioned with each other through the hole retaining spring 20, the shaft retaining spring 21, the pressure cover 22, and the spacer 23. The wheel 17 can rotate along the axis of the axle 19.
[0022] The anti-rotation block 12 is arranged on the head end face of the vehicle body 9, and there are two of them, and their positions correspond to the two upper roller bearing seat shoulders 11 of the upper roller bearing seat 3. The two anti-rotation blocks 12 are respectively processed with thread holes for installing the set screws 13 in the vertical direction. By adjusting the set screws 13, the two upper roller bearing seat shoulders 11 of the upper roller bearing seat 3 are supported to limit the rotation of the upper roller bearing seat 3 and prevent the upper roller bearing seat 3 from tipping over during the roller changing process. The locking nut 14 is used to lock the set screws 13 to prevent loosening.
[0023] The hand-held pull rod 16 is threaded at one end and connected to the mounting hole of the vehicle body 9. The hand-held pull rod 16 is used to manually pull the roll-changing trolley 6 with the upper working roll 4 out of the equipment during the roll-changing process. The hand-held pull rod 16 is only installed on the roll-changing trolley 6 on one side of the roll-changing direction. When three or more roll-changing trolleys 6 are used to perform the roll-changing action during the roll-changing process, only the roll-changing trolleys 6 at both ends close to the upper roll bearing seat 3 need to be provided with anti-rotation devices to prevent the upper roll bearing seat 3 from rotating.
