Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figures 1 to 5 The rolling mill roll surface cleaning device shown includes an H-shaped support frame 1, with two horizontal support plates fixedly installed on the two bottom far ends of the support frame 1, and casters fixedly installed on the bottom of the two horizontal support plates for easy movement.

[0029] Two sliding blocks 23 are slidably mounted on the bottom of the middle crossbeam of the support frame 1. The support frame 1 is equipped with a drive mechanism that drives the two sliding blocks 23 to slide closer or further away.

[0030] Specifically, the drive mechanism includes a first motor 2, which is fixedly mounted on the support frame 1. Two limiting grooves are opened at the bottom of the middle crossbeam of the support frame 1. The two limiting grooves correspond one-to-one with two slide blocks 23, and each slide block 23 is limited and slidably engaged with the corresponding limiting groove.

[0031] A bidirectional threaded rod 3 is rotatably mounted on the bottom of the middle crossbeam of the support frame 1. The bidirectional threaded rod 3 passes through two limiting grooves in the horizontal direction. The two threaded segments of the bidirectional threaded rod 3 correspond one-to-one with the two limiting grooves. Each threaded segment passes through the slide block 23 in the corresponding limiting groove and is threadedly connected to the slide block 23 in the corresponding limiting groove.

[0032] Two support grooves are opened in the middle crossbeam of the support frame 1 along the sliding direction of the two slides 23. The openings of the two support grooves are horizontally opposite each other, and the two limiting grooves are located between the two support grooves and are connected to the two support grooves.

[0033] Two support blocks are fixedly installed on each slide block 23. The two support blocks on each slide block 23 correspond one-to-one with two support slots. Each support block is located in the corresponding support slot and is limited to sliding cooperation with the corresponding support slot.

[0034] Both support grooves are located below the bidirectional threaded rod 3 to prevent the bidirectional threaded rod 3 from being subjected to radial force.

[0035] Each of the two slide blocks 23 has a fixed inclined slide rail 4 at its bottom, and the two inclined slide rails 4 are arranged symmetrically in an inverted V-shape. Each of the two inclined slide rails 4 has a slider 7 installed in a limited sliding position within its rail.

[0036] Specifically, the cross section of the inclined slide rail 4 is cross-shaped, and part of the block of the slider 7 matches the track of the inclined slide rail 4.

[0037] Each inclined slide rail 4 has a guide rod 5 fixedly installed inside the track along the sliding direction of the internal slider 7. The guide rod 5 passes through the block of the slider 7, and the slider 7 and the guide rod 5 are in a limited sliding fit.

[0038] Each guide rod 5 is fitted with a spring 6. One end of each spring 6 is fixedly connected to the slider 7 in the track, and the other end of each spring 6 is fixedly connected to the inclined slide rail 4.

[0039] The roll is located between two sliders 7, and the two trunnions of the roll correspond one-to-one with the two sliders 7.

[0040] Both sliders 7 have a circular through hole in the horizontal direction. The two circular through holes are coaxially aligned and their central axes are parallel to the bidirectional threaded rod 3. The circular through hole on each slider 7 is used for the coaxial insertion of the trunnion of the corresponding roll.

[0041] Two circular perforations are coaxially connected to the ends of the slide block 7, and the two rotating rings 8 are used to coaxially abut against the two axial ends of the roll.

[0042] One of the sliders 7 is equipped with a power mechanism that drives the roller to rotate.

[0043] Specifically, the power mechanism includes a rotating roller 16 for rolling contact with the rolls. Each slider 7 has an arc-shaped mounting groove circumferentially formed along the circular perforation, and each arc-shaped mounting groove communicates with the circular perforation within its slider 7. Multiple horizontal rotating rollers 16 are rotatably mounted in each arc-shaped mounting groove, and the central axis of each rotating roller 16 is parallel to the central axis of the circular perforation.

[0044] Multiple rotating rollers 16 within each arc-shaped mounting groove are arranged at equal intervals along the circumference of the circular perforation, with each rotating roller 16 protruding from the opening of the arc-shaped mounting groove toward the central axis of the circular perforation.

[0045] All rollers 16 are rubber rollers and are used for rolling contact with the trunnions of the rolls.

[0046] One of the sliders 7 is equipped with a power source, and all the rollers 16 on the slider 7 are driven by the power source.

[0047] Specifically, the power source includes a second motor 9, which is fixed on a corresponding slider 7. An annular clearance groove is formed within the slider 7 along the circumference of the circular through hole, and the annular clearance groove communicates with the circular through hole. Multiple rotating shafts 14 are rotatably mounted within the annular clearance groove, and a third gear 15 is fitted onto each rotating shaft 14.

[0048] The multiple rotating shafts 14 on the slider 7 correspond one-to-one with the multiple rotating rollers 16, and each rotating shaft 14 is coaxially fixed to the corresponding rotating roller 16.

[0049] The internal gear ring 13 is coaxially limited and rotatably mounted in the annular relief groove, and all the third gears 15 mesh with the internal gear ring 13.

[0050] A drive shaft 11 parallel to all the rotating shafts 14 is rotatably installed in the annular relief groove. A second gear 12 is fixedly sleeved on the drive shaft 11, and the second gear 12 meshes with the internal gear ring 13.

[0051] The first gear 10 is fixedly mounted on the second motor 9. The slider 7 has a notch that communicates with the annular relief groove, and the second gear 12 passes through the notch and meshes with the first gear 10.

[0052] A spray plate 20 is fixedly installed at the bottom of the middle crossbeam of the support frame 1, and the spray plate 20 is located between two inclined slide rails 4. A cleaning brush 21 for cleaning the rollers is fixedly installed at the bottom of the spray plate 20.

[0053] The cleaning brush 21 is composed of multiple brush strips parallel to the bidirectional threaded rod 3. The length of the multiple brush strips is the same as that of the roller, and the multiple brush strips together form a cleaning brush 21 with a bottom concave shape that matches the roller.

[0054] A water supply assembly for supplying cleaning water to the spray plate 20 is installed on the middle crossbeam of the support frame 1.

[0055] Specifically, the water supply assembly includes a water tank 17, which is fixed to the top of the middle crossbeam of the support frame 1. A water pump 18 is fixedly installed on the water tank 17. The water inlet of the water pump 18 is fixedly connected to the water tank 17 via an inlet pipe, and the water outlet of the water pump 18 is fixedly connected to the spray plate 20 via an outlet pipe 19. The bottom of the spray plate 20 has spray nozzles 22, and the interior of the spray plate 20 has liquid channels. All spray nozzles 22 and the outlet pipe 19 are connected to the liquid channels.

[0056] Working principle: When using this device to clean the surface of the rolling mill rolls, first move the device to the rolls that have been removed from the rolling mill. Then, start the first motor 2. The output shaft of the first motor 2 drives the double-threaded rod 3 to rotate, and the double-threaded rod 3 pushes the two slide blocks 23 to slide closer together. The two slide blocks 23 drive the two inclined slide rails 4 to move closer together, and the two inclined slide rails 4 drive the two sliders 7 to move closer together.

[0057] After the two trunnions of the roll are inserted into the circular holes in the corresponding slider 7, as the output shaft of the first motor 2 continues to rotate, the two rotating rings 8 will coaxially abut against the roll. During this process, the two rotating rings 8 may contact the roll one after the other. In this case, due to the weight of the roll, the rotating ring 8 that contacts the roll first will remain stationary along with the roll. Then, under the action of the reaction force, the support frame 1 as a whole moves in the opposite direction to the direction in which the rotating ring 8 that contacted the roll first moved before coming to rest, until the other rotating ring 8 contacts the roll; at this point, the roll is centered. It should be noted that this application is only for cleaning rolls with one trunnion size.

[0058] Afterwards, once the two rotating rings 8 contact the corresponding axial ends of the rolls, the output shaft of the first motor 2 continues to rotate, and the two inclined slide rails 4 continue to move closer and push the two sliders 7 to slide upwards synchronously. The two sliders 7 drive the rolls to move upwards, while simultaneously compressing the corresponding springs 6.

[0059] When the rollers contact and abut against the cleaning brush 21, the first motor 2 is shut down and the second motor 9 and water pump 18 are started. It should be noted that when the trunnion passes through the corresponding circular perforation, it will squeeze the corresponding roller 16, and ultimately each roller 16 will abut against the corresponding trunnion. To prevent the trunnion from damaging the roller 16, each roller 16 has a rounded corner along its circumferential direction at its axial end.

[0060] Next, the output shaft of the second motor 9 drives the first gear 10 to rotate, the first gear 10 drives the second gear 12 to rotate, and the second gear 12 drives the internal gear ring 13 to rotate. The internal gear ring 13 drives all the third gears 15 to rotate, and all the third gears 15 drive the corresponding rollers 16 to rotate via the rotating shaft 14. All the rollers 16 on the slider 7 rotate and drive the corresponding trunnions to rotate, and the trunnions drive the rollers to rotate. The cleaning brush 21 cleans the rollers.

[0061] At the same time, the water pump 18 draws out the cleaning liquid from the water tank 17 through the water inlet pipe and sprays the cleaning liquid onto the roll through the water outlet 22 on the spray plate 20 through the water outlet 19, thereby rinsing the roll.

[0062] After the roller cleaning is completed, turn off the second motor 9 and water pump 18, and restart the first motor 2. The output shaft of the first motor 2 reverses, the two slide blocks 23 slide away, and the two inclined slide rails 4 move away. At this time, under the action of gravity and the elastic force of the spring 6, the roller and the two sliders 7 move down synchronously. When the two sliders 7 move to the bottom of the inclined slide rail 4, the two sliders 7 stop moving down and move away from the roller along the inclined slide rail 4. At this time, the roller is placed in its original position. After the two slide blocks 23 slide back to their original positions, turn off the first motor 2.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
