Description

Technical Field

[0001] This invention relates to the field of passenger transport device technology, and more particularly to a support device for a passenger transport device. Background Technology

[0002] Escalators or moving walkways, widely used public transportation equipment in public places, are generally referred to as passenger transport devices, with both ends connected to the building. Typically, the end supports of passenger transport devices are fixed or have only one lateral degree of freedom. However, in areas with frequent seismic activity, buildings may sway due to earthquakes. Fixed supports may generate additional stress during building swaying, damaging the passenger transport device. In extreme cases, excessive building swaying could cause the passenger transport device to fall.

[0003] In existing technologies, for example, Chinese invention patent applications published (announcement) CN202988522U and CN204958107U are end support devices for earthquakes. However, both increase the overlap at the ends but only provide one degree of freedom in one direction, i.e., only lateral movement is possible. The above-mentioned publications are simple extensions of existing support methods and cannot solve the problem of passenger transport devices being damaged due to building swaying caused by earthquakes. Summary of the Invention

[0004] The summary of this invention introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This summary is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To solve the above-mentioned technical problems, the present invention provides a support device for a passenger conveying device, comprising: a base, a first sliding plate, a transverse sliding member, a second sliding plate, a rotating member, a third sliding plate, and a longitudinal sliding member;

[0006] The base is fixed to the fixed structure of the building. The inner surface of the base also has a pad. A first sliding piece is provided between the transverse sliding member and the pad. The first sliding piece is fixed to the lower part of the transverse sliding member and can slide between the first sliding piece and the pad.

[0007] The lower part of the lateral sliding member has a first groove, and the first sliding piece is fixed in the first groove; the upper part of the lateral sliding member has a second groove, and the second groove is arc-shaped in the X direction; the rotating member is accommodated in the second groove and can rotate along the arc-shaped surface of the second groove; a second sliding piece is provided between the lateral sliding member and the rotating member, the second sliding piece is fixed in the second groove, and the rotating member and the second sliding piece can slide together;

[0008] The longitudinal sliding member is C-shaped and is set on the rotating member. A third sliding plate is provided between the rotating member and the longitudinal sliding member. The third sliding plate is fixed to the upper surface of the rotating member, and the longitudinal sliding member can slide with the third sliding plate. The inner surface of the longitudinal sliding member also has a pad. The truss of the passenger transport device is supported by the building by being placed on the upper surface of the longitudinal sliding member.

[0009] Preferably, the base is a quadrilateral structure with protrusions around its perimeter, and its inner surface is a plane.

[0010] Preferably, the lateral sliding member has a preset first gap with the inner edge of the raised quadrilateral structure of the base in the X direction, so that the lateral sliding member can only move within a preset range in the base in the X direction; the lateral sliding member has essentially no gap with the inner edge of the raised quadrilateral structure of the base in the Y direction, so that the lateral sliding member cannot move in the Y direction.

[0011] Preferably, the rotating member has downward extensions on both sides in the Y direction, the lower surface of the extensions is lower than the upper surface of the transverse sliding member, and the overlapping portion of the extensions and the transverse sliding member has essentially no gap, so that the rotating member cannot move in the Y direction.

[0012] Preferably, the opening of the longitudinal slider extends to below the upper protrusion of the transverse slider, so that the protrusion is accommodated within the longitudinal slider; the preset gap between the protrusion and the longitudinal slider in the X direction restricts the movement of the longitudinal slider in the X direction by the transverse slider, and the longitudinal slider can move within a preset range in the Y direction.

[0013] Preferably, the inner surface of the opening of the longitudinal slider and the lower part of the upper protrusion of the transverse slider have a preset second gap, so that the longitudinal slider and the rotating member can only rotate within a limited range.

[0014] Preferably, the pad is made of stainless steel.

[0015] Preferably, the coefficient of friction between the first sliding plate and the base is between 0.1 and 0.2.

[0016] Preferably, the coefficient of friction between the second sliding plate and the rotating component is between 0.1 and 0.2.

[0017] Preferably, the coefficient of friction between the third sliding plate and the longitudinal sliding member is between 0.1 and 0.2.

Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0023] like Figure 1 and Figure 2 As shown in the figure, this specific embodiment provides a support device for a passenger transport device, including a base 5, a first sliding piece 6, a transverse sliding member 7, a second sliding piece 4, a rotating member 3, a third sliding piece 2, and a longitudinal sliding member 1.

[0024] The base 5 is fixed to the fixed structure of the building; the base 5 is a quadrilateral structure with protrusions on all sides and a flat inner surface.

[0025] The inner surface of the base 5 also has a pad 8. A transverse sliding member 7 is slidably disposed on the pad 8 within the base 5. A first sliding piece 6 is disposed between the transverse sliding member 7 and the pad 8. The first sliding piece 6 is fixed to the lower part of the transverse sliding member 7 and is slidable between the first sliding piece 6 and the pad 8. The pad 8 is preferably made of stainless steel, which is less affected by environmental factors and makes the coefficient of friction between the first sliding piece 6 and the pad 8 more stable.

[0026] The lateral slider 7 has a predetermined first gap with the inner edge of the raised quadrilateral structure of the base 5 in the X direction, so that the lateral slider 7 can only move within a predetermined range within the base 5 in the X direction. The lateral slider 7 has virtually no gap with the inner edge of the raised quadrilateral structure of the base 5 in the Y direction, so that the lateral slider 7 cannot move in the Y direction. Preferably, the lower part of the lateral slider 7 has a first groove, and the first sliding piece 6 is fixed within the first groove. Figure 1 The horizontal direction is the X-direction, which is also the direction in which the passenger transport device carries passengers. Figure 2 The horizontal direction is the Y direction.

[0027] The upper part of the transverse sliding member 7 has a second groove, which is arc-shaped in the X direction.

[0028] The rotating member 3 is accommodated within the second groove and can rotate along the arcuate surface of the second groove. A second sliding piece 4 is provided between the transverse sliding member 7 and the rotating member 3, and the second sliding piece 4 is fixed within the second groove. The rotating member 3 and the second sliding piece 4 are slidable. The rotating member 3 has downward extensions on both sides in the Y direction. The lower surface of the extension is lower than the upper surface of the transverse sliding member 7, and the overlapping portion of the extension and the transverse sliding member 7 has essentially no gap. Figure 2 As shown, this prevents the rotating part 3 from moving in the Y direction.

[0029] The longitudinal sliding member 1 is C-shaped and is mounted on the rotating member 3. A third sliding piece 2 is provided between the rotating member 3 and the longitudinal sliding member 1. The third sliding piece 2 is fixed to the upper surface of the rotating member 3, and the longitudinal sliding member 1 and the third sliding piece 2 are slidable. The opening of the longitudinal sliding member 1 extends to the lower part of the upper protrusion of the transverse sliding member 7, so that the protrusion is accommodated in the longitudinal sliding member 1. The predetermined gap between the protrusion and the longitudinal sliding member 1 in the X direction is very small, so that the movement of the longitudinal sliding member 1 in the X direction is restricted by the transverse sliding member 7, and the longitudinal sliding member 1 can move within a predetermined range in the Y direction.

[0030] The inner surface of the longitudinal sliding member 1 also has a pad, which is preferably made of stainless steel, making it less affected by environmental factors and making the coefficient of friction between the third sliding piece 2 and the pad more stable.

[0031] The inner surface of the opening of the longitudinal slider 1 and the lower part of the upper protrusion of the transverse slider 7 have a preset second gap, that is, the C-shape of the longitudinal slider 1 and the T-shape of the transverse slider 7 are matched so that the longitudinal slider 1 and the rotating member 3 can only rotate within a preset range.

[0032] The truss of the passenger transport device is supported by the building by being placed on the upper surface of the longitudinal sliding member 1.

[0033] The coefficient of friction between the first sliding plate 6 and the base 5 is preferably between 0.1 and 0.2, the coefficient of friction between the second sliding plate 4 and the rotating member 3 is preferably between 0.1 and 0.2, and the coefficient of friction between the third sliding plate 2 and the longitudinal sliding member 1 is preferably between 0.1 and 0.2.

[0034] The truss of the passenger transport device is mounted on the longitudinal sliding member 1 for a fixed connection. When the seismic wave is in the X direction, the building deforms in the X direction, meaning the beam spacing may decrease or increase. The transverse sliding member 7 moves horizontally in the X direction within the base 5, ensuring that the truss structure is not subjected to compression or tension. When the seismic wave is in the Y direction, the building deforms in the Y direction, and the longitudinal sliding member 1 can move in the Y direction, ensuring that the truss structure is not subjected to bending in the Y direction. Since the building's swaying will cause differences in the height of the support points, a rotating member 3 is provided to compensate for this. This allows the passenger transport device to move with the building's changes during an earthquake.

[0035] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
