Running groove body; 4. First transition running groove; 5. Second transition running groove; 6. Support rod. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] To make the content of the present invention easier to be clearly understood, the following will further elaborate on the present invention according to the specific embodiments in combination with the drawings.

[0015] Figure 1 It is a schematic structural diagram of the rotatable running groove provided by the embodiments of the present application. The device includes a running groove base, a running groove body 3 and a transition running groove. Among them, the transition running groove is hinged at one end of the running groove body 3. In this way, when changing the roll, only need to rotate and turn up the transition running groove and fix it, effectively saving the roll changing time.

[0016] Specifically, there are two running groove bases, which are the first running groove base 1 and the second running groove base 2 respectively. These two running groove bases are arranged between the K1 rolling mill stand and the K2 rolling mill stand, and are arranged in sequence along the connection line direction between the two rolling mill stands. Among them, the running groove base adjacent to the K1 rolling mill stand is the first running groove base 1, and the running groove base adjacent to the K2 rolling mill stand is the second running groove base 2.

[0017] The running groove body 3 is fixedly installed on the first running groove base 1, and the length direction of the running groove body 3 is parallel to the connection direction between the K1 rolling mill stand and the K2 rolling mill stand.

[0018] The transition running groove includes a first transition running groove 4 and a second transition running groove 5. Among them, one end of the first transition running groove 4 is hinged to one end of the running groove body 3 close to the K1 rolling mill stand, and the axis of the first transition running groove 4 coincides with the axis of the running groove body 3. The hinge axis between the first transition running groove 4 and the running groove body 3 extends along the width direction of the running groove body 3. In this way, the first transition running groove 4 can be flipped and stored under the running groove body 3.

[0019] Preferably, a support rod 6 is also detachably installed between the first transition running groove 4 and the first running groove base 1. Refer to Figure 1 , when the first transition running groove 4 and the running groove body 3 are parallel to each other and in the same horizontal plane, both ends of the support rod 6 are fixedly connected to the first transition running groove 4 and the first running groove base 1 respectively. At this time, the support rod 6 can support the first transition running groove 4 to keep the first transition running groove 4 horizontal. And when roll changing and pass changing are required on the rolling line, only the support rod 6 needs to be removed, and then the first transition running groove 4 can be flipped.

[0020] The second transition running groove 5 is fixedly installed on the second running groove base 2. Among them, there are two second transition running grooves 5, and the axes of the two second transition running grooves are both parallel to the axis of the running groove body 3, and the two transition running grooves are in the same horizontal plane. One end of each of the two second transition running grooves 5 is fixedly connected to the end of the running groove body 3 far from the first transition running groove 4.

[0021] In this embodiment, the length of the running groove body 3 is 1515 mm, the length of the first transition running groove 4 is 475 mm, and the length of the second transition running groove 5 is 1000 mm.

[0022] Thus, in the technical solution of the present application, the first transition running groove 4 is hinged at one end of the running groove body 3, and when changing rolls, only this transition running groove needs to be rotated, flipped and fixed, effectively saving the roll changing time.

[0023] In addition to the above embodiments, the present invention can also have other implementation manners; all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
