Abstract

The invention relates to the technical field of chemical production equipment, in particular to a steady long-span gantry raking machine comprising a gantry, a main raking arm and an auxiliary raking arm. The main raking arm and the auxiliary raking arm are movably connected to two support ends of the gantry, the gantry support end provided with the main raking arm is a first gantry end, and an electric rope winch is mounted at the first gantry end. Taking the highest point of the gantry as a boundary, a section close to the main raking arm is a first gantry section, and a section close to the auxiliary raking arm is a second gantry section. Two static pulley blocks are mounted on the first gantry section, two static pulley blocks are also mounted on the main raking arm, a fixing device is mounted on the second gantry section, and a wire rope leading out from the electric rope winch is wound of the pulley blocks. Two suspension pivots are adopted to uniformly disperse stress on the main raking arm, so that maximum yield limit of a material of the main raking arm is increased, running is stable, and service life of the raking machine is prolonged.

Description

technical field

[0001] The invention relates to the technical field of chemical production equipment, in particular to a stable large-span portal rake machine, which is mainly used in coal mines and large chemical fertilizer industries. Background technique

[0002] Portal rake machine is a large-scale automation equipment with high degree of automation, perfect safety measures and high work efficiency. It is an ideal transportation equipment for bulk warehouses. It is mainly used for packaging and transportation of bulk warehouses in large-scale urea industry and glass industry. .

[0003] The portal rake machine is mainly composed of three parts: mechanical transmission system, steel components and control system. The mechanical transmission system part is composed of main and auxiliary rake lifting mechanisms, rake arm mechanism, connecting arm mechanism, walking mechanism, etc.; the steel component part It consists of a door frame and a rake arm. The rake arm structure...
