Embodiment Construction
[0018] Refer to attached Picture 1-1 0, an automatic jacking mechanism for the torch stand, including a boss 2 fixedly connected to the torch basin 1, a telescopic tube and an arched top, the arched top is composed of an arc frame 3 symmetrically, and one end of the arc frame It is detachably hingedly installed on the side of the boss, and the other end is connected to the tractor 4; the telescopic tube is composed of a large tube 51, a middle tube 52 and a small tube 53 with decreasing apertures, and the telescopic tubes in the initial state are all located in the pit. The boss rests on the small tube;
[0019] The arc-shaped frame includes a body, one end of the body is provided with a first lug 301 matched with the hinge assembly, the bottom of the other end of the body is equipped with a wheel shaft 601, and the two ends of the wheel shaft are respectively provided with load-bearing wheels 78. The middle section of the wheel shaft is also fixedly connected with two taper...

The invention provides an arc-shaped rack for a lifting mechanism of a torch platform, comprising a body, wherein one end of the body is provided with a first lug which is matched with a hinge assembly; a wheel axle is arranged at the bottom of the other end of the body; the both ends of the wheel axle is respectively provided with a bearing wheel; the middle section of the wheel axle is fixedly provided with two cone-oriented disks; and the two disks are symmetrically arranged along with the center of the wheel axle. The boss for lifting a torch basin in the invention is lifted by an arched roof, the arched roof is composed of a plurality of arc-shaped racks, the arc-shaped racks are provided with the wheel axles, and drag hooks on a drafter are matched with the middle sections of the wheel axles to drag, thus simplifying the structure, and exerting force on the structure evenly; and when the drag hooks of the drafter approach to the wheel axles, the cone-oriented disks on the wheel axles are beneficial to aligning with the drag hooks in the middle, horizontal degree of freedom of the arc-shaped racks on the ground can be restricted, and the arc-shaped racks are dragged to move along a guide rail until the arc-shaped racks arrive at preset positions to form arched roofs, thus the structure is simple and the stability is good.
Description
(1) Technical field [0001] The invention relates to equipment used in a celebration ceremony at the opening of a large-scale sports meeting, in particular to an arc-shaped frame for a torch platform jacking mechanism used in an ignition ceremony. (2) Background technology [0002] At the 7th Olympic Games in Antwerp, Belgium, 24 years after the birth of the Olympic Games, the main torch lighting ceremony of the Olympic Games appeared for the first time. With the passage of time and the advancement of science and technology, the torch lighting ceremony has also moved forward with the development of the times and has become a highlight of the opening ceremony of the large-scale sports meeting. As the equipment carrying the torch, regardless of its form, structure, function and appearance, although it has shown different styles and levels in previous sports games, it cannot meet the requirements of the opening ceremony of the new sports event. Therefore, it is the only way for...
