Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling for three-roll rolling mills in steel production, and particularly relates to an auxiliary device for disassembling and assembling roll shafts of a rolling mill. Background Art

[0002] In steel production, a three-roll rolling mill is a steel processing device that rolls rod-shaped steel into steel with a specific diameter. In order to roll steel with different diameters, it is often necessary to replace the roll shafts on the three-roll rolling mill. Due to the particularly heavy roll shafts, it is very difficult to install and disassemble the roll shafts. Therefore, it is necessary to use other auxiliary tooling equipment to install and disassemble the roll shafts. There are mainly two existing auxiliary tooling methods: the first is the traditional form of using an overhead crane plus manual labor, which has low production efficiency and safety hazards; the second is the form of a fixed-angle jib crane plus manual assistance, which improves the construction efficiency and personnel safety to a certain extent. However, the overall structure is suspended, and very high requirements are imposed on the strength and structural performance of the entire tooling equipment, and extremely high requirements are imposed on on-site installation.

This auxiliary tooling is a bottom surface type auxiliary tooling, which can conveniently install and disassemble roll shafts, and has good structural stability and high safety. This auxiliary tooling can solve the above problems, but there are still the following defects: due to the limited power of the screw drive device of the walking mechanism, it is easy to have a pause phenomenon during the movement, and it is not easy to control the speed when pushing in or retracting the manipulator, so that the end face of the sliding seat is easy to hit both sides of the screw mounting seat.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

It further includes: a traveling mechanism 3;

[0032] Among them, the traveling mechanism 3 includes a base 31, a sliding mounting seat 32 slidably arranged on the base 31, and a driving component 33 arranged on the sliding mounting seat 32 to make the sliding mounting seat 32 slide along the base 31. The adjusting seat 1 is arranged on the sliding mounting seat 32. The driving component 33 makes the sliding mounting seat 32 reciprocate along the base 31 and drives the adjusting seat 1 and the manipulator 2 to move forward and backward; in this embodiment, sliders 322 are arranged at the bottom of the sliding mounting seat 32. There are four sliders 322, and they are respectively connected to the four corner positions at the bottom of the sliding mounting seat 32 by bolts. In other embodiments of the present utility model, the number of sliders 322 can be set to 2, 3, etc. A slide rail 314 slidably engaged with the slider 322 is arranged on the base 31. Limit plates 311 are respectively arranged at both ends of the base 31. In this embodiment, there are two slide rails 314. The slide rails 314 are fixed to the base 31 by bolts, and the slide rails 314 are located between the two limit plates 311. The limit plates 311 are used to limit the moving position of the sliding mounting seat 32. A buffer 312 is arranged on the limit plate 311 at the head end of the base 31. When the slider 322 at the bottom of the sliding mounting seat 32 slides along the slide rail 314 on the base 31, when it slides to one side of the head end limit plate 311, the buffer 312 can buffer the sliding mounting seat 32 to prevent the sliding mounting seat 32 from colliding with the limit plate 311 during backward movement and causing structural damage.

[0033] As Figure 3 and Figure 4 shown, a groove 313 is formed in the middle of the base 31 along the axial direction. A drag chain 34 is connected to the tail end of the sliding mounting seat 32. One end of the drag chain 34 away from the sliding mounting seat 32 is placed in the groove 313. The drag chain 34 is used to protect the cables used in the traveling mechanism 3.

There are 3 groups of height adjusting components 13, which are respectively connected and matched at the triangular positions of the first adjusting plate 11 and the second adjusting plate 12; each height adjusting component 13 cooperates with each other, and the height adjusting component 13 is used to adjust the distance between the first adjusting plate 11 and the second adjusting plate 12, so as to adjust the height of the manipulator 2; there are 2 groups of angle adjusting components 15, which are located on both sides of the pin shaft and are used to adjust the deflection angles of the connecting plate 14 and the second adjusting plate 12 on both sides of the pin shaft. Among them, the height adjusting component 13 and the angle adjusting component 15 can be set as cylinders or electric push rods, etc. When each height adjusting component 13 extends or contracts simultaneously, the distance between the first adjusting plate 11 and the second adjusting plate 12 can be adjusted; when the two angle adjusting components 15 do not extend or contract simultaneously, the second adjusting plate 12 deflects relative to the connecting plate 14. In other embodiments of the present utility model, the first adjusting plate 11 and the second adjusting plate 12 can be designed as rectangular structures or polygonal structures, the height adjusting component 13 can be set to 4 groups, 5 groups, 6 groups, etc., and the angle adjusting component 15 can be set to 2 groups, 4 groups, etc., which are not specifically limited herein.

[0038] In this embodiment, both the height adjusting component 13 and the angle adjusting component 15 are bolt assemblies;

[0039] Specifically, the height adjusting component 13 includes an adjusting bolt 131, an upper adjusting nut 132, a lower adjusting nut 133 and a locking nut 134; the adjusting bolt 131 passes through the first adjusting plate 11 and the second adjusting plate 12 from top to bottom and is threadedly connected to the locking nut 134.

Moreover, the limiting plate 311 and the buffer 312 are used to buffer the sliding mounting seat 32 to avoid the situation that the sliding mounting seat 32 collides with the limiting plate 311 during backward movement, resulting in structural damage. The automatic installation and disassembly of the roll ring are realized through the cooperation of the traveling mechanism 3 and the manipulator 2.
