[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] As attached Figure 1 , Attachment Figure 2 The utility model shows a completely seismic-resistant fixed structure of the end support of an escalator or moving walkway, including an end support 6 connected to the escalator or moving walkway and an embedded steel plate 7 connected to the surface of the building. The end support 6 includes a connecting portion 61 and an extending portion 62. The connecting portion 61 is connected to the end of the escalator or moving walkway, and the extending portion 62 extends in the horizontal direction. A rubber pad 1 is installed on the upper surface of the embedded steel plate 7. The rubber pad 1 is used to reduce the impact of the escalator vibration on the building, and can also play a role in partial shock absorption and vibration isolation in earthquake conditions. A bottom plate 2 is installed on the upper surface of the rubber pad 1. The bottom plate 2 can be one piece or several pieces, which can be adjusted according to actual conditions. The extension part 62 is connected with a fixing bolt 4, the bottom of the fixing bolt 4 abuts against the bottom plate 2, and the extension part 62 is lifted up. When the fixing bolt 4 is rotated, the distance between the bottom plate 2 and the extension part 62 changes. An optional number of stacked small pads 3 are placed between the bottom plate 2 and the extension part 62. The small pads 3 are used to adjust the end support height. The bottom plate 2 is used to support the fixing bolts 4 when adjusting the height. The height of the extension part 61 is adjusted by the fixing bolts 4 during installation. After the height is adjusted to the right position, the small pads 3 are inserted between the bottom plate 2 and the extension part 62. The number of small pads 3 is determined according to the required height adjustment of the end support. More pads, fewer pads, or even no pads can be inserted. After the small pads 3 are inserted, the fixing bolts can be loosened or directly removed to complete the height adjustment of the end support.

[0022] The two sides of the extension part 62 are provided with side limiting angle steels 5 connected to the embedded steel plate 7. The side limiting angle steels 5 are used to limit the movement of the extension part 62 along the width direction of the escalator or moving walkway. The end of the extension part 62 away from the escalator or moving walkway is provided with an end limiting angle steel 8 connected to the embedded steel plate 7. The extension part 62 abuts against the end limiting angle steel 8 to limit the translation of the end support 6. The end of the extension part 62 away from the escalator or moving walkway extends to the outside of the rubber pad 1 and the bottom plate 2, so that the extension part 62 can directly abut against the end limiting angle steel 8 to reduce the error. The side limiting angle steels 5 and the end limiting angle steels 8 completely fix the end support 6, limiting the horizontal and vertical movement of the end support 6 to resist wind loads or earthquakes to avoid additional damage to passengers.

[0023] In this embodiment, the side limiting angle steel 5 is welded to the end support member 6, and the end limiting angle steel 8 is welded to the extension portion 62. After adjusting the height of the end support member 6, the end support member 6 can be completely fixed by welding the side limiting angle steel 5 and the end limiting angle steel 8. In other embodiments, the side limiting angle steel 5 and the end limiting angle steel 8 may not be welded. The specifications and quantity of the side limiting angle steel 5 and the end limiting angle steel 8 can be determined according to the earthquake level or wind load.

[0024] The small pad 3 is rectangular or irregular in shape, and has an avoidance notch for avoiding the fixing bolt 4 .

[0025] When used for ordinary single-truss or double-truss escalators or moving walks, if attached Figure 1 , Attachment Figure 2 As shown, the extension part 62 of the end support member 6 is connected to the top of the connecting part 61, and the extension part 62 and the connecting part 61 are integrally formed, and the overall structure is simpler to implement the function. When used for a large-span single-truss or double-truss escalator or moving walkway, as shown in the attached Figure 3 , Attachment Figure 4 As shown, the extension portion 62 of the end support member 6 is welded to the middle portion of the connecting portion 61, and a plurality of reinforcing members 63 connected to the connecting portion 61 are welded to the upper surface of the extension portion 62, so that the strength is higher and the structure is more stable.

[0026] The anti-seismic fully fixed structure of the end support of the escalator or moving walk of the utility model has a simple structure, good integrity, ordinary materials, low cost, can resist wind load, and can be used for earthquake resistance, and can adapt to different countries and regions, earthquakes of different levels. The side limit angle steel 5 and the end limit angle steel 8 completely fix the end support 6, limit the horizontal and vertical movement of the end support 6 to resist wind load or earthquake action, limit the left and right displacement under the action of earthquake, and prevent the truss from swinging left and right under the action of earthquake to cause additional damage to passengers. The end support height is adjustable, and the extension part 62 is lifted by the tightening bolt 4, and the small pad 3 is inserted to adjust the height, avoiding the insertion of the gasket by lifting, saving installation cost; it is easy to install, and only simple on-site operation is required. Whether it is an escalator or a moving walkway, wind load or earthquake, frequent earthquake or rare earthquake, this solution can be used, and it has wide applicability.
