Abstract

A gate-type bucket-wheel stacker-reclaimer walking beam hoisting mechanism capable of achieving energy-saving control belongs to the field of machinery and comprises a hydraulic system composed of a plunger hydraulic cylinder and a hydraulic pump station, a plunger hydraulic cylinder head chain wheel group and a roller chain connected on a walking beam and a door leg and meshed with a chain wheel. The pump station comprises two parallel plunger pumps, two protection one-way valves, two overflowing valves connected with the one-way valves and a three-position four-way electro-hydraulic reversing valve. Modification of the mechanism includes that a hydraulic pump is changed into a variable displacement plunger pump, a hydraulic lock is added, two hydraulic locks are connected with the plunger hydraulic cylinder directly in a rigid mode, and a hydraulic unlocking branch composed of the one-way valves, the overflowing valves, an energy accumulator, a pressure relay, the electromagnetic reversing valve and a one-way speed adjusting valve is added between a main oil path of the output end of the protection one-way valves at a pump port and the hydraulic locks. The gate-type bucket-wheel stacker-reclaimer walking beam hoisting mechanism has the advantage that the hydraulic system efficiency is improved, heat generation quantity is reduced, and energy consumption of a movable beam hoisting control system is greatly reduced.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a door-type stacker-reclaimer for stacking or extracting and removing solid particle bulk materials to a storage site. Background technique [0002] Such as figure 1 , figure 2 The portal type bucket wheel stack including movable beam 1, roller mechanism 2, fixed beam 3, belt conveyor 4, rigid door leg 5, movable beam lifting mechanism 6, machine walking mechanism 7, tail car 8, and flexible door leg 9 Reclaimer (hereinafter referred to as gantry bucket wheel machine), as a continuous and efficient bulk material loading and unloading conveying equipment, because of its high recovery rate, certain mixing effect, easy management of stockpile, simple structure and easy operation The advantages of convenience and easy realization of automatic control can be widely used in large-scale thermal power plants, industrial and mining enterprises and port bulk material storage yards. ...
