Description

Technical Field

[0001] This utility model belongs to the technical field of disassembly and hoisting devices, and is applied to the replacement operation of brush rollers in the cleaning section of galvanizing pretreatment equipment. In particular, it relates to a brush roller disassembly device for the cleaning section. Background Technology

[0002] The galvanizing production line requires multiple sets of brush rollers for cleaning strip steel. Over time, the brush bristles will fall off and decrease in number, affecting the cleaning effect. Therefore, it is necessary to adjust the brush rollers (such as...) Figure 1 As shown, the brush roller body has bearing seats at both ends for timely replacement. Currently, when replacing brush rollers in the factory area, workers need to use a roller replacement cart to disassemble the brush rollers, move them to a convenient location for hoisting, and then hoist them using an overhead crane. Roller replacement work generally requires the cooperation of multiple people and is time-consuming, thus requiring a long downtime for the equipment.

[0003] The existing hoisting device in the factory is based on the structure of patent number CN202322596817.7, publication number CN220926022U, and is a utility model patent for hoisting fixtures. The counterweight structure of this device can be adjusted to balance the brush rollers; however, adjusting the weight of the counterweight is inconvenient, and the adjustment requires manual operation. Finding the balance point again each time workpieces of different weights is very time-consuming. Therefore, the existing device needs to be improved to save time on disassembly and hoisting operations. Summary of the Invention

In the following description of the embodiments, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this patent and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this patent.

[0028] In the following description of the embodiments, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0029] Example: See Appendix Figure 1-5 A cleaning section brush roller disassembly and hoisting device includes a steel structure beam 2 and a counterweight structure 3. One end of the steel structure beam 2 can be detachably installed with a brush roller. The end of the steel structure beam 2 is provided with a detachable buckle groove 201, and the buckle groove 201 is provided with a plurality of positioning holes. The buckle groove 201 is fixed to the roller head at the end of the brush roller by installing locking bolts 11 in the positioning holes.

[0030] The bottom of the steel structure beam 2 is equipped with a track 202, and the top of the steel structure beam 2 is equipped with four lifting lugs 203. During each hoisting operation, it is hoisted from two points and balanced using the lever principle. Each lifting lug 203 is equipped with a photoelectric sensor 4. A drive device 5, a lead screw 6, and a power control box 7 are mounted on the bottom of the steel structure beam 2 via a bracket. The drive device 5 drives the lead screw 6 to rotate. The upper part of the counterweight structure 3 is a movable seat 301, and a counterweight plate 302 is fixedly mounted below the movable seat 301. The counterweight plate 302 of the counterweight structure 3 is attached to the bottom of the movable seat 301 by fixing bolts. Generally, a maximum of four counterweight plates 302 are mounted. A sensor plate 303 is fixedly mounted on the top of the movable seat 301. The sensor plate 303 is L-shaped, and its top surface is the detection point of the photoelectric sensor 4. The movable seat 301 is equipped with wheels 304 that match the track 202. The movable seat 301 is fixedly integrated with the slider of the lead screw 6 and moves on the track 202 as the lead screw 6 rotates.

[0031] The steel beam 2 is equipped with travel limiting devices 8 near both ends, and a buffer pad 9 is provided on the side of the travel limiting device 8 facing the counterweight structure 3. This is a protective structure designed to prevent operator error and to prevent damage to the steel beam 2 and the counterweight structure 3 due to misoperation. A photoelectric sensor 4 is provided at each end of the top of the steel beam 2 to detect the travel limit position of the counterweight structure 3. A support leg 10 is fixed at each end of the bottom surface of the steel beam 2, allowing the device to be placed stably on the ground before lifting, facilitating the connection of the brush roller.

[0032] The power control box 7 is fixed on the support foot 10 near the drive device 5. The power control box 7 is electrically connected to the photoelectric sensor 4 and the drive device 5, and is also equipped with an audible and visual alarm.

[0033] Workflow: For the initial hoisting, first determine the lifting point and counterweight positions, and conduct a balancing test on different rollers to ensure safety. After achieving balance, mark the photoelectric sensor 4 and determine the lifting position.

[0034] When the brush roller in the pre-galvanizing cleaning section needs to be replaced, the device is hoisted to the appropriate position using a crane, and the snap-fit ​​groove 201 and the brush roller are assembled together. The drive unit 5 drives the lead screw 6 to rotate, causing the counterweight structure 3 to move forward or backward slowly to the appropriate position. Once the steel structure beam 2 is in a horizontal position, the photoelectric sensor 4 detects the sensing plate 303, sends a feedback signal to the power control box 7, and cuts off power to the drive unit 5, thus ensuring that the counterweight position does not change. Simultaneously, an audible and visual alarm sounds to remind the user to pay attention to safety. The brush roller and the device are then smoothly lowered to the ground using the crane. Workers remove the damaged brush roller, replace it with a new one, and then the new brush roller is hoisted again.

[0035] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims. These modifications all fall within the protection scope of the present invention.
