Description
Technical Field
[0001] The utility model belongs to the technical field of stage fire curtain installation, and particularly relates to an auxiliary trolley used for assembling stage fire curtains. Background Art
[0002] The stage fire curtain is a vertical rigid fire wall located above the stage entrance. Its height and width are slightly larger than the size of the stage entrance. It can move up and down along the guide rails. When a fire occurs, it is used to separate the audience area and the performance area. It has a large area and a large mass. Most of the current fire curtains are assembled into a whole by multiple curtain blocks. The mass and volume of each curtain block are still relatively large. During installation and construction, manpower cannot directly move and adjust the curtain blocks. The installation and construction site conditions of the fire curtain are limited. There are generally two assembly processes: first, vertical assembly from bottom to top into a whole. This method requires the erection of scaffolding and lateral support. The scaffolding needs to be removed after the assembly is completed, which increases additional costs and involves high-altitude operations, which is very dangerous; second, assembling into a whole on the horizontal ground and then lifting it into a vertical state. This overall lifting is prone to deformation of the fire curtain, and there is swinging when lifting and flipping, which poses a risk of collision and hitting. At the same time, these two assembly processes usually require the use of auxiliary equipment and tools such as crowbars, rollers, forklifts, cranes, etc. to move and adjust the curtain blocks. However, using these equipment and tools cannot quickly and accurately align the installation holes and can easily damage the curtain. Utility Model Content
