The invention belongs to the technical field of crown block units, and discloses a special graphitization clamp crown block which comprises a block body, a control frame is fixedly mounted in the block body, a lifting rod is fixedly mounted on the bottom surface of the control frame, and a clamping frame is fixedly connected to the bottom surface of the lifting rod. An oil pumping mechanism is used for introducing pressure oil into each group of communicating sleeves through a distribution sleeve, and the continuously introduced pressure oil is used for pushing two groups of push rods on the side surface of an elastic plate to move, so that the elastic plate is bent and deformed, and the elastic plate is in full contact and extrusion with the surface of a graphite crucible during bending deformation; and sufficient oil pressure is introduced into the inner cavity of the elastic plate in a matched mode, so that the elastic plate is locally expanded, the cambered surface contact area of the elastic plate and the graphite crucible is further increased, the friction force effect is improved by enlarging the clamping area, and the clamping effect is improved. Therefore, the actual clamping and stacking stability is greatly improved.
本发明属于天车机组技术领域,且公开了一种石墨化专用夹钳天车,包括车体,所述车体的内部固定安装有控制架,所述控制架的底面固定安装有升降杆,所述升降杆的底面固定连接有夹持架。本发明通过利用泵油机构经由分配套向着每组连通套中通入压力油,通过利用不断通入的压力油推动弹性板侧面上的两组推杆移动,从而使得弹性板弯曲变形,并在弯曲变形与石墨坩埚表面充分接触并挤压,从而增加了对石墨坩埚夹持时的接触面,大大增加了摩擦力,且通过配合足量的油压通入到弹性板的内腔中,使得弹性板局部膨胀,进一步提高弹性板与石墨坩埚的弧面接触面积,通过扩大夹持面积提高摩擦力作用,从而大大提高了实际夹持堆垛的稳定性。
