Description

Technical Field

[0001] The utility model relates to the technical field of escalators, in particular to an earthquake-resistant and wind-resistant non-fixed structure supported at the end of an automatic escalator or a moving walkway. Background Art

[0002] In the prior art, there are few non-fixed structures for the end supports of escalators that are earthquake-resistant and wind-resistant. There are many end support structures that take earthquakes into consideration, but there are few end support structures that take wind loads into consideration. Some end supports can achieve left and right limit and adapt to "inter-layer displacement", but the structure is complex and the height cannot be adjusted. The end platform depth dimension is required to be error-free, which is difficult to achieve in actual situations; some end supports can achieve left and right limit and adapt to "inter-layer displacement", but it is necessary to insert gaskets by lifting and adjust the end support height, which is troublesome to install and has a high installation cost. Utility Model Content

[0003] In view of the above-mentioned technical problems, the purpose of the utility model is to provide a non-fixed structure for supporting the end of an escalator or a moving walkway, which is earthquake-resistant and wind-resistant, and is easy to install and cost-effective.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A non-fixed structure for supporting the ends of an escalator or a moving walkway with earthquake resistance and wind load resistance, comprising an end support connected to the escalator or moving walkway and an embedded steel plate connected to the surface of a building, the end support comprising a connecting portion and an extending portion, the connecting portion being connected to the end of the escalator or moving walkway, the extending portion extending in a horizontal direction, a rubber pad being provided on the upper surface of the embedded steel plate, a bottom plate being provided on the upper surface of the rubber pad, a fixing bolt being provided on the extending portion, the bottom of the fixing bolt being abutted against the bottom plate, the spacing between the bottom plate and the extending portion changing when the fixing bolt is rotated, an optional number of stacked small pads being provided between the bottom plate and the extending portion, side limiting angle steels connected to the embedded steel plate being provided on both sides of the extending portion, the side limiting angle steels being used to limit the movement of the extending portion along the width direction of the escalator or moving walkway.

[0006] Preferably, the extending portion is connected to the top of the connecting portion, and the extending portion and the connecting portion are integrally formed.

[0007] Preferably, the extension portion is connected to the middle portion of the connection portion by welding, and a plurality of reinforcing members connected to the connection portion are welded to the upper surface of the extension portion.

[0008] Preferably, the bottom plate and the rubber pad are of equal length.

[0009] Preferably, the small pad is rectangular or irregular in shape.

[0010] Preferably, there are four fixing bolts, which are arranged in pairs at both ends of the extension portion along the width direction.

[0011] Preferably, there are six fixing bolts, which are distributed at both ends and the center of the extension portion along the width direction.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] The utility model has a simple structure, wide application range, convenient processing and installation, simple materials, low cost, and can freely adjust the height of the end support, while being used to resist wind loads and earthquakes.

[0021] 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.

[0022] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. 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.

[0023] As attached Figure 1 , Attachment Figure 2 The utility model shows an earthquake-resistant and wind-resistant non-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 62 is connected with a fixing bolt 4, and the bottom of the fixing bolt 4 abuts against the base plate 2, and the extension 62 is lifted up. When the fixing bolt 4 is rotated, the spacing between the base plate 2 and the extension 62 changes. A number of optional stacked small pads 3 are placed between the base plate 2 and the extension 62. The height of the extension 61 is adjusted by the fixing bolt 4 during installation. After the height is adjusted in place, the small pads 3 are inserted between the base plate 2 and the extension 62. The number of small pads 3 is determined according to the required height adjustment of the end support, and more pads, less 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. Both sides of the extension 62 have side limit angle steels 5 connected to the embedded steel plate 7, and the side limit angle steels 5 are used to limit the extension 62 from moving along the width direction of the escalator or moving walkway. After the end support 6 is adjusted in height, it can be welded to the embedded steel plate 7 through the side limit angle steel 5 to limit the lateral movement of the escalator to resist wind load or earthquake to avoid additional damage to passengers. The specifications and quantity of the side limit angle steel 5 can also be determined according to the earthquake level or wind load.

[0024] When used for ordinary single-truss or double-truss escalators or moving walks, if attached Figure 1 , Attachment Figure 2 As shown, the extension portion 62 of the end support member 6 is connected to the top of the connecting portion 61, and the extension portion 62 and the connecting portion 61 are integrally formed, and the overall structure is simpler to implement the function.

[0025] When used for long-span single-truss or double-truss escalators or moving walkways, as shown in the attached Figure 3 , Attachment Figure 4 , Attachment Figure 5 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 lengths of the bottom plate 2 and the rubber pad 1 are equal. The bottom plate 2 and the rubber pad 1 can be continuous. Figure 4 As shown, it can also be separated, as shown in the attached Figure 2 As shown, select according to the actual situation.

[0027] The small pad 3 can be rectangular or other irregular shapes, and avoids the fixing bolts 4 when it is inserted between the base plate 2 and the extension portion 62 .

[0028] As attached Figure 2 As shown, when used for ordinary single-truss or double-truss escalators or moving walkways, there are four fixing bolts 4, which are installed two by two at both ends of the extension 62 along the width direction. Figure 4 As shown, when used for a large-span single-truss or double-truss escalator or moving walkway, there are six fixing bolts 4 distributed at both ends and the center of the extension portion 62 in the width direction, making the installation more reliable.

[0029] The earthquake-resistant and wind-resistant non-fixed structure of the end support of the escalator or moving walkway of the utility model has a simple structure, good integrity, common materials and low cost. It can adapt to the inter-story displacement of fixed buildings in different countries and regions under the action of earthquakes, can adapt to the expansion joints across buildings, prevent the buildings from expanding and contracting due to climate and temperature changes, limit the left and right displacement under the action of earthquakes, and prevent the trusses from swinging left and right under the action of earthquakes to cause additional harm to passengers, and can resist wind loads to avoid the trusses from shaking left and right, which affects the safety of the truss rigidity and strength; the end support height is adjustable, and the extension part 62 is lifted by the tightening bolts 4, and the small pad 3 is inserted to adjust the height, avoiding the insertion of gaskets in a lifting manner, saving installation costs; it is easy to install, and only simple on-site operations are required.
