Steel-coil-sampling fixing device

Abstract

The invention provides a steel-coil-sampling fixing device, and belongs to the technical field of steel coil sampling. The device comprises a land-roll driving roll, a land-roll driven roll, a universal driving shaft arranged at the outer side of the land-roll driven roll, swing arms connected to two end of the universal driving shaft, an upper pinch roll arranged between terminal parts of the swing arms, a lower pinch roll located below the upper pinch roll, and a swing hydraulic cylinder which is connected with the swing arms, and can control lifting and falling of the upper pinch roll by driving the swing arms. The steel-coil-sampling fixing device can ensure that steel coils are cut according to required lengths, reduce the cutting loss caused by overlength lengths of unfolded steel coils, and the security in the process of steel sample cutting can be improved.

Description

Technical field [0001] The invention relates to the technical field of steel coil sampling, in particular to a steel coil sampling fixing device. Background technique [0002] When the rolled steel coils in the main rolling line of steel production are transported to the steel coil warehouse, sampling devices are required to be cut and sampled at the specified length according to the technical requirements and sent to the quality inspection department for the performance of the steel coils. [0003] The original sampling device is a simple ground roller structure. The sampling process is as follows: the crane hoists the steel coil on the ground roller, manually removes the straps, the ground roller rotates to open the steel coil, and the manual cutting gun is used to cut the steel coil manually Divide into two parts: scrap plate and steel coil. Take a small rectangular piece on the scrap plate as a test sample. The rest of the scrap plate is handed over to the scrap steel; the grou...

Problems solved by technology

[0004] When using the original equipment for sampling, there are the following problems: After the steel coil is opened, due to its own curvature, there is a tendency to roll back, which is easy to cause injury to the operator

In order to prevent workers from being injured by steel coil rewinding, the steel coil must be opened for a long distance before cutting, usually at least 6 meters, and the length of sampling required is usually 1 meter, 2 meters, or 3 meters depending on the steel type. , so many cut parts are changed from qualified products to waste products, resulting in cutting loss and great waste
