Assembly line for production of steel-structure protection doors

Abstract

The invention relates to the technical field of production of civil air defense doors, provides an assembly line for production of steel-structure protection doors, and aims to solve the problems thattraditional assembling is manual sequential assembling, various fittings are disordered, the time consumed for assembling is long, more manpower and equipment are required for assistance in assembling of door frames and door leaves having very high weight and the assembling efficiency is low. The assembly line comprises transfer trolleys and the door leaves vertically fixed to the transfer trolleys; the door leaves pass through the first station, the second station, the third station and the fourth station on the assembly line sequentially for circulating machining; a workshop cross beam extending in the circulating direction of the door leaves is arranged above the first station, the second station, the third station and the fourth station; assembling mechanisms are arranged in the positions, corresponding to the second station and the third station, of the workshop cross beam; and a door frame assembling mechanism is arranged in the position, corresponding to the third station, of the workshop cross beam. The assembly line is particularly applicable to quick assembling of the steel-structure protection doors and has the relatively high social use value and application prospects.

Description

technical field [0001] The invention relates to the technical field of production of civil air defense doors, in particular to an assembly line for the production of steel structure protective doors. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double protective airtight doors and airtight doors, and a variety of civil air defense equipment such as single and double protective airtight doors and airtight doors with living thresholds. [0003] Among them, the steel protective door is mainly used for the entrance and exit of engineering personnel and equipment. It has a certain ability to resist shock waves and can prevent radioactive contamination, biological warfare agents and chemical warfare agents from penetrating into the project. The characteristic of this type of door is that the resistance...
