Lift bridge in water

Abstract

The invention discloses a lifting bridge in water, which comprises an arch bridge body and an orbit arranged in the water, wherein the bridge body consists of two unit bridges arranged symmetrically, the side of the lower end part of the unit bridge is provided with a roller wheel matched with the orbit, and the orbit is fixed at the bottom of the water through a support frame; and the bridge body also comprises a towing device for towing the unit bridges to slide along the orbit, wherein a tow rope is fixedly connected with a fixed connection point of the rear end of the tow rope after fixedly connected with the fixed connection point of the front end of the tow rope and sequentially rounding a pulley of the pulley block and a wound roll, and the unit bridge in the initial state is arranged aslant and is submerged into the water, the unit bridge after towing to be raised is positioned above the water, and platform sections of the two unit bridges are level. In the invention, by adopting the towing device to be matched with the orbit, the unit bridges realize the lifting or sinking through towing, thereby providing a special scene atmosphere and visual perception as well as colorful showing effect. Compared with the structure of vertically lifting, the lifting bridge shortens the raising vertical distance and reduces the construction cost.

Description

(1) Technical field [0001] The invention relates to a lifting bridge in water, which is suitable for occasions such as performances. (2) Background technology [0002] With the continuous improvement of living standards, the audience's requirements for performance effects are also getting higher and higher. As an indispensable part of the performance, the props of the performance play an important role in the effect of the performance. Usually, the bridge body used in performances is a movable solid prop placed on the stage, supplemented by other scenery to show the small bridge and clear water. Although it can make the audience understand the scene, it is far from realistic, especially in today's entertainment industry. It is more common to perform on the water stage. Normally, the bridge is placed on the water surface, although the effect is realistic, but it takes up space, and it is not suitable for the plot requirements of water and no bridge. The lifting method requ...
