Automatic hoisting device for large-scale hood gate

Abstract

The invention discloses an automatic hoisting device for a large-scale hood gate, comprising left / right column assemblies, a hoisting cylinder assembly, a connecting assembly of the left / right columns, a guide rail assembly, a doorframe assembly, a safety brake assembly, a buffer assembly and light screen protection assemblies. The device is characterized in that the left / right column assemblies are arranged on a machine station, and are connected into an integral body by a front top plate and a front baffle plate of the connecting assembly, so the rigidity and the stability of the whole hood columns are enhanced. Hinge supports of the cylinder are arranged on a cylinder installing plate of the left / right columns, and a shaft-extension end of the cylinder is connected with a U-shaped bayonet of two sides of the doorframe. Front shoe plates and rear shoe plates of the guide rail installation assembly are fixed on the machine station. Before adjustment, space between the rear shoe plates ensures the left / right guide rails installing plates arranged on the rear shoe plates to be in parallel with the doorframe. A solenoid valve controls an air inlet direction of the cylinder and guarantees the cylinder telescoping to provide power for the doorframe and the doorframe slides along the guide rail direction, so automatic open and closure of the doorframe are realized.

Description

technical field [0001] The invention relates to the field of automatic doors for large equipment, in particular to an automatic lifting device for large hood doors. Background technique [0002] The hood doors of traditional large-scale equipment such as 6-axis PCB drilling machines and edge milling machines are manually opened due to their large spans (attached). figure 1 ), its structure is that the upper end of the door frame 17 is equipped with hinge support 15 to hang on the hood, the operator pulls the door handle to make the door turn up or down, and the gas springs 16 are installed on both sides of the uprights 18, which play a supporting role. This method requires manual operation, which affects the operation of the machine tool, and is inefficient; there is a danger of hand-jamming and bumping; it is especially difficult for female operators with small strength to use. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the purpose of this pa...
