Description

Technical Field

[0001] The utility model relates to an inspection device, in particular to a roller taper inspection tool. Background Art

[0002] In the wire rod workshop of the metallurgical industry, the use of finishing mills is of great importance. They are used in large quantities and malfunction frequently, and the finishing mill roll box plays a decisive role. It plays a key role both in production and in wire rod quality control. In particular, the roller shafts on the on-site finishing mill roll box can cause production failures and shorten the service life of the roll box. In severe cases, a series of failures such as steel accumulation and roll ring explosion may occur in the finishing mill, which requires replacement of the finishing mill roll box. If a roll box failure occurs during the night shift, the high ambient temperature on site, the night shift professionals have already left work, the replacement work environment is small, the installation precision requirements are extremely high, and the night shift operators have poor technical skills, resulting in a long replacement time.

[0003] The utilization rate of the roller box of the finishing mill in the bar and wire workshop plays a decisive role, because the roll box is close to the rolled workpiece, and the roll shaft of the roll box is the most fragile component of the rolling mill. Since the roll shaft of the roll box cannot be detected online, sometimes the inner wall of the cone sleeve is not cleaned, the center line of the rolling line is biased, and the roll ring is not flushed well, resulting in a roll ring explosion. When troubleshooting, it seems that there is no abnormality in the roll shaft on the surface, but after the actual finishing mill has failed, the roll box, especially the roll shaft, has been slightly damaged and cannot be identified with the naked eye. Since the equipment is installed on the machine, the equipment cannot be opened for inspection, resulting in continued rolling on the machine. During the operation of the equipment with the problem, due to the slight movement of the roll shaft, impurities such as thin oil pollution enter the roll box, making the equipment unable to be used normally and the fault amplified.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following Figures 1 and 2 The technical solutions of the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0025] Example 1: Figure 1 As shown, the utility model discloses a roller taper inspection tool, comprising a taper sleeve 1 and a drive arm 2. The taper sleeve 1 has a tapered cavity along its axis that is compatible with the roller. The outer shape of the taper sleeve 1 is a circular cylinder, a tapered cylinder, or a square cylinder. The taper sleeve 1 can be fitted onto the corresponding roller through the tapered cavity within it, allowing for rapid online inspection of the roller's taper and whether it is wobbling, thereby determining whether the roller can continue to function normally. The drive arms 2 include two symmetrically arranged on the outer wall of the taper sleeve 1, which facilitate docking of the taper sleeve 1 with the roller.

[0026] Example 2: Figure 2 As shown, the driving arm 2 is hingedly connected to the tapered sleeve 1 through the hinge part 3. The driving arm 2 can adjust the connection angle with the tapered sleeve 1 through the hinge part 3, thereby meeting the docking installation of the tapered sleeve 1 and the roller shaft in the narrow space of the roller box.

[0027] In a preferred embodiment, if Figure 2 As shown, the hinged portion 3 includes a connecting block 4 fixedly connected to the side wall of the cone sleeve 1, with an articulated lug 5 provided on the outside of the connecting block 4. A hinged slot 6 is provided at the inner end of the driving arm 2. An open limit slot 7 is provided on the end of the hinged slot 6 away from the driving arm. The limit slot 7 is correspondingly mounted on the outside of the articulated lug 5. The articulated slot 6 is hingedly connected to the articulated lug 5 via a hinge pivot. This hinged portion 3 can meet the requirements of adjusting the connection angle between the driving arm 2 and the cone sleeve 1, meeting the installation requirements of confined spaces.

[0028] In a preferred embodiment, if Figure 2As shown, the hinge pivot is a hinge screw 8, which includes a screw and a limiting nut arranged at one end of the screw. The limiting nut is correspondingly arranged on one side of the hinge slot block 6 to play a limiting role. The threaded end of the hinge screw 8 passes through the hinge ear block 5 and exits at the other side of the hinge slot block 6. This end of the hinge screw 8 is provided with a rotating part 9 threadedly connected to the screw. The rotating part 9 includes a threaded sleeve 91 adapted to the threaded end of the screw. A driving handle 92 for driving the threaded sleeve to rotate is provided on one side of the threaded sleeve 91. The threaded sleeve 91 can be driven by the driving handle 92 to rotate forward or reverse along the screw, thereby tightening or loosening the rotating part 9 and the hinge screw 8; when the rotating part 9 is tightened, the relative fixation of the position of the hinge slot block 6 and the hinge ear block 5 can be achieved, thereby achieving the working position fixation after the relative position of the driving arm 2 and the cone sleeve 1 is adjusted into place.

[0029] In a preferred embodiment, a guide slider is provided at the root of the limiting groove 7 of the articulated groove block 6, and an arc-shaped surface is provided at the corresponding end of the guide slider and the articulated ear block 5. This arrangement can improve the stability of the rotation adjustment of the articulated groove block 6 and the articulated ear block 5.

[0030] In a preferred embodiment, the driving arm 2 is a driving cross bar, and an anti-slip sleeve is provided at the far end of the driving cross bar. The driving cross bar can be used to conveniently achieve docking installation of the cone sleeve 1 and the roller shaft.

[0031] The economic benefits generated by the application of this utility model are:

[0032] According to the workshop's dispatch log, the finishing mill in the twin-high-speed rolling mill workshop experiences an average of one malfunction per month, with each malfunction lasting over 40 minutes, cumulatively impacting 480 minutes annually. The roll taper inspection tool, after its implementation, reduced the self-inspection time during thermal shutdown to less than 10 minutes, bringing the cumulative impact down to 120 minutes annually, saving 360 minutes of production time. Based on the current twin-high-speed rolling mill production capacity, rolling 80 billets per hour, each weighing 2.3 tons, and generating a 200 yuan / ton benefit, the annual benefit from this application is: 360 minutes x 80 billets / 60 minutes x 2.3 tons / bill x 200 yuan / ton = 220,000 yuan.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
