Abstract

The invention discloses a stacker-reclaimer. The stacker-reclaimer comprises a portal base, a slewing bearing, a rotary plate, an arm frame, a bucket wheel, a pitching oil cylinder and a portal column, and further comprises a counterweight frame, a counterweight block and a counterweight oil cylinder. The rotary plate is arranged on the portal seat, and the slewing bearing is connected with the rotary plate and the portal base to enable the rotary plate to rotate around a rotation center. One end of the arm frame is hinged to the rotary plate, the other end of the arm frame is connected with the bucket wheel, and the portal column is vertically connected to one end, close to the rotary plate, of the arm frame. One end of the pitching oil cylinder is hinged to the rotary plate, and the other end of the pitching oil cylinder is hinged to the portal column. One end of the counterweight frame is connected with the portal column. The counterweight oil cylinder and the counterweight block are arranged on the counterweight frame, and the counterweight block slides on the counterweight frame under the driving of the counterweight oil cylinder. According to the stacker-reclaimer, differentcounterweight moments can be obtained by changing a moment arm of the counterweight block, the gravity center of the upper structure can be controlled within a very small range near a hinge point of the arm frame according to balance requirements at different pitching angles, the load of the pitching oil cylinder and the slewing bearing can be reduced, and the safety performance can be improved.

Description

technical field

[0001] The invention relates to the technical field of material stacking and reclaiming equipment, in particular to a stacking and reclaiming machine. Background technique

[0002] The stacker-reclaimer is an efficient equipment for the continuous loading and unloading of bulk bulk materials in modern industry. Coke, sand and gravel) storage yard stacking operations. The stacker and reclaimer is a track-type loading and unloading machine that uses the bucket wheel to continuously take materials, and then uses the belt conveyor of the equipment itself to continuously stack and take materials. It is a special machine in the bulk material storage yard, which can be combined with the unloading (ship) machine, belt conveyor, ship (vehicle) machine, etc. to form a storage yard transportation system. The stacker-reclaimer has high operating efficiency and is easy to realize automation, and has been widely used at home and abroad.
