The roll changing device 4 provided by the invention has the structure shown in fig. 3 and 4, and comprises a roll changing trolley, wherein the bottom of the roll changing trolley is provided with rolling wheels 44. The roll changing carriage can be moved to one side of the wringing roller assembly 3 under the push of an operator or the drive of a drive mechanism. The roll changing vehicle is provided with a roll bearing platform 43, and the roll bearing platform 43 can adopt a lifting structure or a fixed height structure. After the roll changing carriage moves to one side of the wringing roller assembly 3, the roll bearing platform 43 is aligned with the wringing platform 34 in the wringing roller assembly 3. The roll platform 43 and the wringing platform 34 are now in alignment, and the wringing roll 31 is transferred to the roll platform 43 by pushing it axially. In addition, in order to prevent the wringing roller 31 from rolling on the roller bearing platform 43, the roller bearing platform 43 is also provided with a roller bearing groove. After the wringing roller 31 enters the roller bearing platform 43, the side wall of the roller bearing groove can limit the wringing roller 31, and the wringing roller is prevented from rolling off the roller bearing platform 43.

In the roll changing process, the roll changing trolley needs to be strictly aligned with the wringing roll component 3, and the injury of personnel caused by the slipping of the wringing roll 31 in the roll changing process is avoided. The roll changing device 4 further comprises a roll changing track 42, and the roll changing track 42 can extend from the storing position of the wringing roll 31 to one side of the wringing roll assembly 3. The roll changing vehicle is arranged on the roll changing track 42 and can directly move to the position connected with the wringing platform 34 along the roll changing track 42, so that the operation of adjusting the position in the axial direction of the wringing roll 31 is omitted, and the alignment efficiency is improved. In addition, in order to reduce the opposite pressure, a rail bracket 41 is arranged below the roller changing rail 42, and the rail bracket 41 can be made of square steel pipes, I-shaped steel and other materials.

Optionally, to prevent the roll changing carriage from displacing during the roll changing process, the roll changing track 42 has a positioning hole. Specifically, the position of the positioning hole corresponds to the alignment position of the roll platform 43 and the wringing platform 34. The locating hole sets up along vertical direction, and the lower part of roll changing car is equipped with locking mechanism 45. The locking mechanism 45 comprises a telescopic rod which can be inserted into the positioning hole, and when the roller changing vehicle moves in place, the telescopic rod extends out of the positioning hole and is inserted into the positioning hole. At the moment, the locking mechanism 45 and the roll changing track 42 are locked, so that the roll changing trolley is prevented from moving. Of course, the user may also use a latch, an air cylinder, or the like as the locking mechanism 45, which is not limited herein.

Optionally, in one embodiment of the present application, the wringing roller assembly 3 is provided with a triple wringing platform 34. The roll changing vehicle is provided with 3 roll bearing platforms 43 with fixed height, and the height of the 3 roll bearing platforms 43 is respectively corresponding to the height of the three-layer wringing platform 34. Of course, the user can also set 6 roll supporting platforms 43 as required, each layer of the wringing platform 34 corresponds to two roll supporting platforms 43, one roll supporting platform 43 is used for receiving the old wringing roll 31, and the other roll supporting platform 43 is used for storing the new wringing roll 31.

Alternatively, in another embodiment of the present application, the roll changing device 4 employs a roll supporting platform 43 with a lifting structure. Specifically, the roll changing trolley is further provided with a lifting mechanism, and the lifting mechanism is arranged below the roll bearing platform 43. The lifting mechanism can refer to a cylinder or a scissor fork mechanism in the prior art and the like. After the roll changing carriage is moved into position, the lifting mechanism lifts the roll bearing platform 43 to a height corresponding to the wringing platform 34. Of course, the user can also combine the fixed-height roller bearing platform 43 with the lifting structure roller bearing platform 43 according to the requirement, which is not limited herein.

In this embodiment, the roll changing device 4 includes a roll changing track 42 and a roll changing carriage that moves along the roll changing track 42 to one side of the wringer roll assembly 3. The operator then detaches the coupling 2, separates the wringing roller 31 from the wringing motor 1, and then pushes the wringing roller 31 axially to transfer it to the roll platform 43. The transferring process of the wringing roller 31 does not need hoisting operation, so that the replacement efficiency is improved, and the accident risk is reduced.

The invention also provides water quenching tank equipment which comprises any one of the roll changing devices 4. The water quenching tank device also comprises a wringing roller assembly 3, the wringing roller assembly 3 comprises a plurality of layers of wringing platforms 34, and a wringing roller 31 is arranged above each layer of wringing platform 34. One side of the wringing roller component 3 is provided with a motor support, and the wringing motor 1 is arranged in the motor support and is connected with the wringing roller 31 through a coupling 2.

Optionally, for the convenience of the operator, the lower part of the bearing seat 32 is provided with a translation pulley 33, and the rotating shaft of the translation pulley 33 is perpendicular to the axial direction of the wringing roller 31. The operator pushes the wringing roller 31 axially, the translation pulley 33 replaces sliding friction through rotating friction, the friction force between the wringing roller 31 and the wringing platform 34 is reduced, and the wringing roller 31 is replaced quickly. In addition, the roller bearing platform 43 can also be arranged on the translation track corresponding to the translation pulley 33, and the translation pulley 33 rolls along the translation track, so that the risk of rolling off the wringing roller 31 is further reduced. Of course, the user can also use the side wall of the roller bearing groove as a translation track according to the requirement.

In this embodiment, the two ends of the wringing roller 31 are connected with the bearing seat 32, and the lower part of the bearing seat 32 is provided with a translation pulley 33. When the wringing roller 31 is replaced, an operator detaches the connecting piece between the bearing seat 32 and the wringing platform 34 and then pushes the wringing roller 31 along the axial direction, so that the replacement of the wringing roller 31 can be completed quickly, and the roller replacement efficiency is further improved.
