Guide device of weighing pull rod

The utility model relates to the technical field of billet continuous casting blank weighing in the ferrous metallurgy industry, in particular to a guide device of a weighing pull rod. A shaft sleeveis fixed to a support, a connecting rod is a cylindrical long rod, the middle of the connecting rod is sleeved with the shaft sleeve, a key groove is axially formed in the connecting rod, one end of an anti-rotating pin is fixed to the support, and the other end of the anti-rotating pin is inserted into the shaft sleeve and clamped in the key groove of the connecting rod. And the other end of theaxial positioning pin is inserted into the shaft sleeve. The utility model ensures that the piston rod of the hydraulic cylinder is not influenced by the shaking of a casting blank below, and prolongsthe service life of the hydraulic cylinder. 本实用新型涉及钢铁冶金行业小方坯连铸铸坯称重技术领域，特别是一种称重拉杆的导向装置。本实用新型的轴套固定在支架上，连杆为一个圆柱形长杆，连杆中部外面套在轴套中，连杆轴向设置键槽，防转销一端固定在支架上，另一端插入轴套并卡在连杆的键槽内；轴向定位销一端固定在支架上，另一端插入轴套。本实用新型保证了液压缸活塞杆不受下方铸坯晃动的影响，延长了液压缸的使用寿命。
