Problems solved by technology

However, due to the heavy weight of the LED screen itself, the existing LED screens are all fixedly installed on the external wall of the building.
As for the lifting LED screen, especially large-scale lifting LED screen has not been reported yet.
Due to the need to consider the impact of wind pressure and other outdoor climate and environmental factors on the structure and transmission of large-scale lifting LED screens, it is still a project that is difficult to realize in the construction industry

Embodiment Construction

[0026] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0027] A large-scale lifting screen exhibition machine with a large-span synchronous lifting arm, which is mainly composed of a lifting screen 7, a fixed arm 3, a telescopic arm 1, a driving mechanism 2, a transmission mechanism and a counterweight mechanism 5. The fixed arm part of this large-scale lifting screen exhibition machine is fixedly installed on the end of the building with an inclination angle of 17 degrees through the installation frame 4. The top of the lifting screen is flush with the top surface 6 of the building in the retracted state.

[0028] The lifting screen is composed of a truss and a plurality of LED screen units installed on the truss. The tops on both sides of the lifting screen are respectively fixed to the tops ...

Abstract

The invention relates to a large-scale lifting screen performance machine with a long-span synchronous lifting arm, which is mainly formed by a lifting screen, fixed arms, telescopic arms, a driving mechanism, transmission mechanisms and a balance weight mechanism, wherein the tops of both sides of the lifting screen are fixed to the top ends of the two telescopic arms respectively; the two telescopic arms are arranged in the two fixed arms longitudinally in a lifting way; a middle driving mechanism which corresponds to the top ends of the fixed arms is fixedly arranged on a fixture in the rear of the lifting screen; the synchronous transmission mechanisms are arranged on both sides in the lateral direction of the driving mechanism; the driving mechanism drives the telescopic arms to drive the lifting screen to lift by the transmission mechanisms; and the balance weight mechanism are connected to the bottom ends of the two telescopic arms and the lifting screen commonly. The large-scale lifting screen performance machine has scientific and reasonable structural design, runs stably and is safe and reliable and the design desire of the extra large-scale outdoor lifting screen is realized, so that audiences can enjoy the spectacular scene of lifting large-scale light-emitting diode (LED) display frames slowly at a far distance.

Description

technical field [0001] The invention belongs to the field of exhibition machinery, in particular to a large-scale elevator screen exhibition machinery with a large-span synchronous lifting arm. Background technique [0002] At present, setting up LED screens on the outside of buildings is already a very common way of publicity and exhibition. However, due to the heavy weight of the LED screen itself, the existing LED screens are all fixedly installed on the external wall of the building. As for the lifting LED screen, especially large-scale lifting LED screen has not been reported yet. Due to the need to consider the impact of wind pressure and other outdoor climate and environmental factors on the structure and transmission of large-scale lifting LED screens, it is still a project that is difficult to realize in the construction industry. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide ...
