Description

Technical Field

[0001] The utility model relates to the field of rolling equipment, in particular to a strip break traction device. Background Art

[0002] In the downstream of strip production, it needs to be rolled by multiple rolling mills to form a suitable specification. Combining with the actual production, it can be known that the strip will break occasionally during the rolling process. After the break, the strip is laid on the conveying roller bed and needs to be re-tracted to the downstream rolling mill. Affected by stress and external force, the strip will form an outward or inward bend at the break. Coupled with the influence of the strip weight and temperature, it is very difficult to smoothly pull the broken end to the next rolling mill to resume the rolling process by manual clamping and pulling alone, and the labor force is very large. Therefore, a convenient and practical strip break traction device that can liberate human power is needed. Summary of the Utility Model

[0003] Aiming at the problems existing in the background art, the purpose of the utility model is to provide a strip break traction device, which effectively solves the problems existing in the background art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As Figures 1-4 shown, a belt-breaking traction device according to this embodiment includes two symmetrically arranged units 1. The unit 1 includes an electric crawler mobile platform, a lift platform 2 that is liftably arranged on the electric crawler mobile platform, a translation platform 3 that is movably arranged left and right on the lift platform 2, and a driven roller set arranged on the translation platform 3. An active roller set that cooperates with the driven roller set is also arranged on the electric crawler mobile platform. Specifically, the electric crawler mobile platform includes a chassis 4, a counterweight 5 and a gantry 6 fixedly arranged on the chassis 4. The active roller set is arranged on the gantry 6. Two mutually independent electric crawlers 7 are arranged in parallel on the chassis 4. The electric crawler 7 is an existing product, and its structure will not be described in detail here. By controlling the start and stop of the electric crawler 7, the unit 1 can be controlled to move forward, backward or turn, so that the unit 1 can move to a suitable position.

[0021] A guiding slide bar 8 and a worm screw lift 9 are cooperatively arranged between the lift platform 2 and the counterweight 5. The number of guiding slide bars 8 is four, which are respectively located at the four corners of the bottom of the lift platform 2. The worm screw lift 9 is located in the middle below the lift platform 2 and is responsible for driving the lift platform 2 to lift and lower. A slider 10 is arranged on the translation platform 3. An electric telescopic rod 11 and a slide rail 12 that cooperates with the slider 10 are arranged on the lift platform 2. One end of the electric telescopic rod 11 is fixedly connected to the translation platform 3, and the translation platform 3 is driven to slide left and right by the electric telescopic rod 11.

[0022] The driven roller group includes a rotatably arranged driven roller 13 on the translation platform 3 and a driven friction wheel 14 coaxially fixed on the driven roller 13; the driving roller group includes a driving roller 15 driven by a reduction motor and a driving friction wheel 16 coaxially arranged on the driving roller 15. The driving friction wheel 16 includes two arc-shaped petals 17 detachably arranged on the driving roller 15 through countersunk bolts; the materials of the driving friction wheel 16 and the driven friction wheel 14 are both rubber; by replacing the arc-shaped petals 17 with different heights, the gap between the driving roller 15 and the driven roller 13 can be controlled;

[0023] An arc-shaped baffle 18 cooperating with the driven roller 13 is further arranged on the gantry 6. The arc-shaped baffle 18 is located inside the driven friction wheel 14. A plurality of vertical guide rollers 19 are arranged near the arc top of the arc-shaped baffle 18. When the strip steel 20 is conveyed between the driving roller 15 and the driven roller 13, horizontal shaking may occur. The side of the strip steel 20 contacts the vertical guide rollers 19, which limits the horizontal shaking of the strip steel 20 and will not damage the side of the strip steel 20, and can also protect the safety of the driven roller group and the driving roller group, avoiding being frictionally cut by the strip steel 20.

[0024] A ladder 21 and a top platform 22 are further arranged on the gantry 6 to facilitate the maintenance of the components of the unit 1.

[0025] The working principle of this embodiment is as follows:

[0026] After the strip steel 20 breaks, move the two units 1 to both sides of the conveying roller bed 23, roughly align the driven roller group with the area 24 upstream of the break, which is called the clamping area, then control the driven roller 13 to move downward and inward and insert it under the strip steel 20, and then control the driven roller 13 to jack up the strip steel 20 until it is in close contact with the driving roller 15. First, control the driving roller 15 to reverse, roll the bent part at the break of the strip steel 20 and roughly flatten it, then move the unit 1 and cooperate with the upstream rolling mill to pull the strip steel 20 to the downstream rolling mill. The staff holds the break of the strip steel 20 with tools and finely adjusts the height, sends the break of the strip steel 20 into the rolling roller group of the downstream rolling mill, slowly start the rolling mill, and then make the driven roller 13 move away from the driving roller 15 and withdraw from the unit 1; compared with the prior art, in this embodiment, by using two units 1 in cooperation, the broken strip steel 20 can be easily picked up and pulled to the downstream rolling mill. The cooperation between the driving roller group and the driven roller group can roughly flatten the bend at the break of the strip steel 20, making the feeding of the strip steel 20 between the roller groups of the downstream rolling mill more accurate and smooth; this embodiment works stably and reliably, greatly reducing the labor intensity and having strong practicability.
