Abstract

The invention provides an automatic lifting device of a heavy-load roof door. The device is provided with four main body mechanisms, wherein the four same main body mechanisms are fixedly arranged on four corners of a wind tunnel roof door respectively; a roof rood support arm is arranged at the upper end of a movable guide rail by a horizontal-sliding roller; the lower end of the movable guide rail is connected with the upper end of a jacking spiral lifter by a self-adjustment flexible mechanism; two sides of the movable guide rail are connected with a guide plate by a guide roller; the guide plate is connected with a base and a fixed guide rail; a left side and a right side at the lower end of the movable guide rail are provided with an adjustable positioning support pillar respectively; and a pulling tray moving motor is connected with a pulling tray. Each industrial control computer is provided with an operation interface and a motion control program, and by a motion control card and an IO expansion card of the computer, motion control of an alternating current servo motor can be realized by using a motion control function of the control card. By the device, the heavy-load roof door can be automatically opened and closed, and the device is stable, reliable and safe to operate.

Description

technical field [0001] The invention belongs to the technical field of lifting devices, and in particular relates to an automatic lifting device for a heavy-duty top door. The invention is suitable for the automatic lifting of the top door of the wind tunnel or the automatic lifting of other heavy-duty objects. Background technique [0002] The large-scale low-speed wind tunnel in the prior art is mainly composed of straight-through, closed-end tandem double test sections, and the wind tunnel structure includes a wind tunnel body, a measurement and control system, a power system, a model support system, and a top door lifting system. Since the top door of the wind tunnel has a self-weight of 13 tons and a span of 10 meters, the opening and closing of the top door controls the installation and removal of the test model and test equipment into the hole, and the top door lifting system controls the opening and closing of the top door. The existing overhead door lifting system ...
