Grinding head lifting counterweight device of steel grinding machine

Abstract

The invention provides a grinding head lifting counterweight device of a steel grinding machine. The counterweight comprises a fixed pulley, a steel cable, a cross bar, a clump weight and a counterweight motor, wherein the fixed pulley is fixedly arranged at the top end of a frame; the steel cable is wound on the fixed pulley; one end of the steel cable is fixedly connected with a grinding wheel device, and the other end of the steel cable is fixedly connected with the fixed pulley; one end of the rotating shaft of the fixed pulley is fixedly connected with one end of the cross bar, and the other end of the cross bar is connected with the counterweight motor; the clump weight is movably arranged on the cross bar; the rotating shaft of the counterweight motor passes through the clump weight through a threaded connecting rod and is in threaded connection with the clump weight; the clump weight is movably placed on the cross bar; a bracket is arranged below the counterweight motor; and the bracket is fixedly arranged on the frame. The counterweight can be used for enabling the grinding wheel device in the steel grinding machine to move up and down by virtue of a moment arm principle, is resource-saving, and is convenient and practical.

Description

technical field [0001] The invention relates to a counterweight, in particular to a lifting counterweight device for a grinding head of a steel grinding machine.
