Vertical hinged door special for lifting opening

Abstract

The invention discloses a vertical hinged door special for a lifting opening. The door is specially used for the lifting opening. The door comprises a door plate and a translation device; A translation motor and a translation shaft are installed on the door plate, a guiding chain wheel is fixedly installed on the translation shaft, a driving chain wheel is fixedly arranged on a motor shaft of thetranslation motor, the driving chain wheel is in power linkage with the guiding chain wheel through a guiding chain, and guide rail chain wheels are fixedly installed at the left and right ends of thetranslation shaft; anti-disengagement mechanisms are arranged at the left and right guide rail chain wheels, and each anti-disengagement mechanism is provided with two anti-disengagement chain wheels; the translation device is provided with a left track, a right track, a left guide rail chain and a right guide rail chain which are arranged in parallel, and a chain body of each guide rail chain isin engagement connection with the anti-disengagement chain wheel, the guide rail chain wheel and the anti-disengagement chain wheel on the same side in the shape like a Chinese character 'ji'; the tracks and a traction base are fixed to the ground or wall at the two sides of the lifting opening, the door plate covers the lifting opening in a limiting mode by the tracks, the vertical hinged door can effectively resist wind pressure at the lifting opening, the lifting opening can be opened and closed by operating and starting the translation motor, convenience and rapidness are achieved, no worker assistance is needed on site, and operation is safe and reliable.

Description

technical field [0001] The invention provides a special casement door for a hoisting opening. Background technique [0002] In order to replace equipment and large spare parts in buildings such as the main workshop of large-scale power plants and mine crushing buildings, equipment hoisting openings are reserved. For safety reasons, the hoisting openings must be tightly closed with door panels when not in use to avoid falling accidents, but the hoisting openings are not only The area is large and the wind passing through the hoisting opening is also strong, so a heavy door panel is generally used to cover the hoisting opening to avoid displacement due to wind pressure; each time the door panel is opened or closed, it is usually lifted by a crane or The vehicle is towed and moved. Since the hoisting opening is usually square, and the door panel is movable to cover the hoisting opening, there is wind interference when moving, and sometimes manual correction is required.

[0002] In order to replace equipment and large spare parts in buildings such as the main workshop of large-scale power plants and mine crushing buildings, equipment hoisting openings are reserved. For safety reasons, the hoisting openings must be tightly closed with door panels when not in use to avoid falling accidents, but the hoisting openings are not only The area is large and the wind passing through the hoisting opening is also strong, so a heavy door panel is generally used to cover the hoisting opening to avoid displacement due to wind pressure; every time the door panel is opened or closed, it is usually lifted by a crane or The vehicle is towed and moved. Since the hoisting opening is usually square, and the door panel is movable to cover the hoisting opening, there is wind interference when moving, and sometimes manual correction is required. A little carelessness will cause the door panel to fall. Therefore, it is troublesome and dangerous to operate the door panel displacement every time.
