Description

Graphite carbon brick clamping tool Technical Field The utility model relates to the technical field of graphite carbon brick production, in particular to a graphite carbon brick clamping tool. Background In the process of producing the graphite carbon bricks, a lifting mode is generally required to transport the large-size graphite carbon bricks so as to facilitate the operation requirements of tapping, slotting, stacking and the like. The utility model patent with publication number CN205616446U discloses a double carbon block clamp device, which can realize the aim of clamping two carbon blocks at one time, but because the bending angle of a right bending clamping arm and a left bending clamping arm is fixed, when clamping graphite carbon bricks with smaller or larger sizes, the right bending clamping arm and the left bending clamping arm easily form an included angle with the surfaces of the graphite carbon bricks, so that contacts on a left clamping plate and a right clamping plate cannot be fully contacted with the surfaces of the graphite carbon bricks, relative sliding easily occurs, scratches are easily formed on the surfaces of the carbon blocks by the contacts, the quality of the carbon blocks is influenced, and secondly, because the longitudinal lengths of the right bending clamping arm and the left bending clamping arm cannot be adjusted, the clamping points of the right bending clamping arm and the left bending clamping arm are higher, and the clamping stability is poor when clamping the graphite carbon bricks.
