Edge safety device for entry and exit pits of cold rolling mill and method of use thereof

Abstract

The invention relates to the field of program control safety devices for pits, in particular to a limb safety device for a cold rolling unit access port pit and an application method thereof. The limb safety device for the cold rolling unit access port pit comprises a pit (11) and a steel coil car (12), and is characterized by further comprising saddle bases (2), a guide rail (3), a slide plate (4), an extension cylinder (5), fences (6), a rotating cylinder (7), a pneumatic valve table (8) and a controller (9); the saddle bases (2) are respectively arranged on two sides of the edge of the pit (11); and the fences (6) are rotationally arranged on two sides of the edge of the pit (11). The application method of the limb safety device for the cold rolling unit access port pit is characterized by being performed according to the steps of: (a) preparation; and (b) interlocking control. The limb safety device for the cold rolling unit access port pit is simple in structure, convenient to use, accurate in control, safe and reliable.

Description

technical field [0001] The invention relates to the field of safety equipment for metal rolling, in particular to an edge safety device for pits at the entrance and exit of a cold rolling mill and a method for using the same. Background technique [0002] Existing cold rolling mills need to check the surface and side of the steel coil to ensure the quality of the product when the steel coil enters and exits. When routinely inspecting steel coils, the operator needs to straddle the passage of the steel coil trolley around the saddle. This passage is a narrow and long pit with a depth of 1.4m and a width of 0.5m, which is a necessary place for the steel coil trolley to transport steel coils. The channel cannot be closed. At the same time, the operation is relatively frequent. Every time the steel coil is replaced, there are 4 inspection stations at the entrance and 2 inspection stations at the exit. The risk of safety accidents is very high. In order to avoid the risk of fall...

Problems solved by technology

When routinely inspecting steel coils, the operator needs to straddle the passage of the steel coil trolley around the saddle. This passage is a narrow and long pit with a depth of 1.4m and a width of 0.5m, which is a necessary place for the steel coil trolley to transport steel coils. The channel cannot be closed. At the same time, the operation is relatively frequent. Every time the steel coil is replaced, there are 4 inspection stations at the entrance and 2 inspection stations at the exit. The risk of safety accidents is very high.

In order to avoid the risk of falling, there is currently a way to cover potholes with artificial covers, but because the covers are too heavy, and there is no positioning, and the edge is also lacking the protection of the fence, the potential safety hazard cannot be fundamentally eliminated. At the same time, frequent operations increase labor intensity
