Embodiment Construction
[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0061] Such as figure 1 with Figure 4 As shown, the present invention proposes a hidden long-span movable bridging device, which acts as a bridge and is used to bridge the stage and the ignition platform. In the present invention, for ease of description, when the movable bridge device is working, the end of the movable bridge device docked with the stage is the rear end, and the end of the movable bridge device docked with the ignition platform is the front end.
[0062] The movable bridging device includes a bottom guide rail 2 , a chassis 3 , an outer frame 6 , an inner frame 9 and a hydraulic electric control device 1 . There are two bottom guide rails 2, and the two bottom guide rails 2 are arranged on the ground in parallel and at intervals.
[0063] Chassis 3 is arranged on bottom guide rail 2 top, and a plurality of wheels 7 are in...

The invention discloses a hidden long-span movable bridging device and a bridging method, and relates to the field of stage machinery, wherein a plurality of wheels and a plurality of jacking mechanisms are mounted on the bottom surface of the chassis; an outer frame having a U-shaped channel; the bottom of the rear end of the outer frame is hinged to the chassis; a middle guide rail is arranged at the bottom of the U-shaped channel; two ends of the telescopic tilting mechanism are respectively hinged to the front end of the outer frame and the front end of the chassis; the inner frame comprises a transverse section and a bent section, the transverse section is inserted into the U-shaped channel, and a roller set is arranged at the bottom of the transverse section; panels are laid on the top surfaces of the outer frame and the inner frame; a hydraulic electric control device; the top face of a rear end panel of the outer frame is in lap joint with the top face of the stage. The top face of a front end panel of the bent section is in lap joint with the top face of the ignition platform. The invention further discloses a bridging method of the hidden long-span movable bridging device. The bridge approach task of the stage and the ignition platform can be efficiently completed, the occupied external space is small, and the bridge approach platform can serve as a step from the ground to the stage.
Description
technical field [0001] The invention relates to the field of stage machinery, in particular to a hidden long-span movable bridging device and a bridging method. Background technique [0002] In some large-scale sports games, the sports field has a large stage, and there is an ignition platform not far from the large stage; the stage usually has a certain height from the ground, and the ignition platform is higher than the stage. The performers need to land on the stage from the ground, and the ignition personnel need to land from the stage to the ignition platform. In the actual sports meeting scene, after completing the construction of the stage and the ignition platform, it is usually necessary to artificially build multi-step steps, leading from the ground to the stage, and from the ground or the stage to the ignition platform, but the way of building steps has long construction period and occupation Disadvantages of larger space.
