Description

Technical Field

[0001] The invention relates to rolling mill maintenance, in particular to a looper anti-falling safety support device in rolling mill maintenance operations. Background Art

[0002] During the maintenance process of the rolling mill, the loop swing table needs to be lifted up and then the inlet trolley is withdrawn. During this maintenance process, there is a height difference between the loop swing table and the bottom plate after it is lifted up. The loop swing table may automatically fall down due to gravity and the action of the hydraulic cylinder and injure the maintenance personnel. In serious cases, casualties may occur.

[0003] Therefore, it is necessary to develop new safety devices in a targeted manner to overcome the above problems. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a loop anti-fall safety support device for rolling mill maintenance operations, which improves the safety of maintenance operations, reduces operational safety risks, and avoids safety accidents.

[0005] Technical solution: The present invention provides a looper anti-falling safety support device in rolling mill maintenance operations, which is characterized in that an anti-falling safety support device is arranged below the looper swing table, and the anti-falling safety support device is located on the side of the trolley.

[0006] Among them, the anti-fall safety support device has a tube structure on the top and a plate structure on the bottom.

[0007] Wherein, the tube structure is made of steel tube, and the plate structure is made of steel plate.

[0008] Wherein, the steel pipe and the steel plate are connected by welding.

[0009] Wherein, the outer diameter of the steel pipe is 195 mm and the inner diameter is 115 mm.

[0010] Wherein, the steel plate comprises a vertical plate and a horizontal plate, and triangular inclined plates are arranged on both sides of the vertical plate.

[0011] Wherein, the height of the vertical plate is 450mm and the width is 200mm.

[0012] Wherein, the thickness of the transverse plate is 20 mm and the length is 500 mm.

[0013] Wherein, the height of the triangular inclined plate is 100 mm.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: In view of the problem that the looper swing table has a height difference with the bottom plate after being lifted, and there is a risk of falling, a support device is manufactured and installed under the swing table, which is easy to adjust, convenient to use, safe and reliable. The present invention improves the safety of maintenance operations, reduces operational safety risks, and avoids safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0017] The anti-falling safety support device for the looper in the rolling mill maintenance operation of the present invention is provided below the looper swinging platform and is located on the side of the trolley. The anti-falling safety support device has a tube structure above and a plate structure below. The tube structure is made of a steel pipe and the plate structure is made of a steel plate. The steel pipe and the steel plate are connected by welding.

[0018] The outer diameter of the steel pipe of the present invention is 195 mm, and the inner diameter is 115 mm. The steel plate includes a vertical plate and a horizontal plate, and triangular inclined plates are arranged on both sides of the vertical plate. The height of the vertical plate is 450 mm, and the width is 200 mm. The thickness of the horizontal plate is 20 mm, and the length is 500 mm. The height of the triangular inclined plate is 100 mm.

[0019] The invention aims to solve the problem that the looper swing table has a height difference with the bottom plate after being lifted, and there is a risk of falling. A support device is manufactured and installed under the swing table, which is easy to adjust, convenient to use, safe and reliable. The invention improves the safety of maintenance work, reduces the safety risk of work, and avoids safety accidents.
