Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, an embodiment of the present invention provides a retractable evacuation platform support, including a main structure 1, a bearing component for bearing an evacuation platform, and a supporting structure for supporting the bearing component, wherein the bearing component includes a fixed station installed on the main structure 1 at one end, a movable station near or far from the main structure 1, and a locking unit for locking the fixed station and the movable station, and the movable station is installed at a position where the fixed station is far from the main structure 1. In this embodiment, the main structure 1 is a stable part, and it may be a main body of a subway, a city railway, an inter-city railway section tunnel, a bridge, and the like, on which both the bearing assembly and the support structure are to be installed to ensure their stability. The bearing assembly is optimized to be a fixed platform and a movable platform which are combined to bear the evacuation platform, wherein the fixed platform is horizontally and fixedly arranged on the main structure 1, and then the movable platform is arranged at a position, far away from the main structure 1, of the fixed platform. And after the adjustment is completed, the fixed table and the movable table are locked through the locking unit.
The following are specific examples:
in order to optimize the above scheme, please refer to fig. 1 to 3, the fixed table has an inner cavity recessed inwards from an end surface far away from the main structure 1, and the movable table is movably disposed in the inner cavity. In this embodiment, the fixed table has an inner cavity, and the movable table can move in the inner cavity, so as to achieve the purpose of adjusting the width formed by the combination of the fixed table and the movable table. And after the adjustment is completed, the fixed table and the movable table are locked through the locking unit. Preferably, the fixed station can adopt H shaped steel 20 among the prior art, and the movable table can adopt channel-section steel 21 among the prior art, and after H shaped steel 20 kept flat horizontally, both ends all had the cavity about it, and channel-section steel 21 can move about in this cavity. The adoption of the H-shaped steel 20 and the channel steel 21 can reduce the cost of the bracket, and the bearing capacity of the H-shaped steel 20 and the channel steel 21 is strong, so that the evacuation platform borne by the H-shaped steel is safer. The fixed station is formed by horizontally splicing a plurality of H-shaped steel 20, and the splicing adopts bolt connection. Of course, other constructions are possible, such as a fixed table made of reinforced concrete with an internal cavity in which the channel 21 is movable.
