Abstract
Description
Technical Field
[0001] The utility model relates to an intermediate support component and an escalator system, and more particularly to an intermediate support component with earthquake resistance function and a corresponding escalator system. Background Art
[0002] Long-span escalators require intermediate support assemblies to support the trusses. However, existing intermediate support assemblies only support the trusses vertically and fail to secure them laterally. If the trusses are not securely secured laterally during an earthquake, they are likely to be damaged by violent lateral swaying, potentially leading to the collapse of the escalator.
[0003] Therefore, it is desired to provide an intermediate support assembly and a corresponding escalator to improve the above-mentioned defects in the prior art. Utility Model Content
[0004] According to a first aspect of the present invention, an intermediate support assembly is proposed for supporting a truss of an escalator, comprising: a support member having two support portions, a crossbeam and two legs, the two support portions being respectively used to support the trusses on both sides of the escalator, the crossbeam being connected between the two support portions, and the two legs extending downward from both sides of the crossbeam; two support plates being respectively arranged under the two legs and configured to respectively support the two legs, and the support plates being fixed; wherein the intermediate support assembly further comprises two reinforcement members, one of the two reinforcement members being against the corresponding leg along a first direction, and the other of the two reinforcement members being against the corresponding leg along a second direction, the first direction being opposite to the second direction and both being parallel to the extension direction of the crossbeam, and the two reinforcement members being respectively fixed to the corresponding support plates.
[0005] According to this solution, the two reinforcements respectively prevent the truss from moving in the first direction and the second direction, so that the truss is fixed in the lateral direction, reducing the possibility of the truss being damaged due to violent lateral swing in the event of an earthquake, and improving the seismic performance of the escalator.
[0006] In some aspects, each of the two reinforcements may have a horizontal portion extending in a horizontal plane and fixed to the corresponding support plate, and a vertical portion extending in a vertical plane and abutting the corresponding leg.
[0007] In some aspects, each of the two reinforcement members may be arranged on a side of the leg away from the corresponding truss.
[0008] According to this solution, the reinforcement is arranged on the inner side of the leg, which helps to reduce the space occupied by the intermediate support assembly.
[0009] In some embodiments, the reinforcement may further include a reinforcement plate having a horizontal edge, a vertical edge, and a beveled edge, wherein the horizontal edge contacts the horizontal portion, the vertical edge contacts the vertical portion, and the beveled edge is connected between ends of the horizontal edge and the vertical edge.
[0010] According to this solution, the reinforcing plate can increase the strength of the reinforcing member, further improving the seismic performance of the escalator.
[0011] In some aspects, the reinforcing plate may be provided with holes extending in a direction perpendicular to the surface of the reinforcing plate.
[0012] According to this solution, when installing the intermediate support assembly, the operator can conveniently carry the reinforcement plate through the hole on the reinforcement plate.
[0013] In some aspects, the intermediate support assembly may further include an intermediate plate disposed between the legs and the support plate, wherein a surface of the intermediate plate facing the support plate is formed of a low-friction material.
[0014] According to this solution, the intermediate support assembly constrains the freedom of movement of the truss in the transverse direction, but does not constrain the freedom of movement of the truss in the running direction of the escalator, which contributes to the stability of the truss structure in the event of an earthquake.
[0015] In some aspects, the low friction material may be polytetrafluoroethylene.
[0016] In some aspects, the middle panel may be secured to the legs.
[0017] In some aspects, the support plate and the reinforcement member may be integrally formed.
[0018] According to a second aspect of the present invention, an escalator system is provided, comprising: a truss and the intermediate support assembly according to the first aspect of the present invention, wherein the support member is fixed to the truss. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, scheme and advantages of the technical solution of the present invention more clear, the following will be combined with the drawings of specific embodiments of the present invention to clearly and completely describe the technical solution of the present invention. Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.
[0042] For a clearer description, unless otherwise specified, the meanings of the directional nouns appearing in this article are as follows: vertical direction refers to the direction perpendicular to the ground, running direction refers to the direction in which the escalator moves, and horizontal direction refers to the direction perpendicular to both the vertical direction and the running direction.
[0043] Figure 1 and Figure 2 The schematic diagram and exploded view of the intermediate support assembly 100 according to an embodiment of the present invention are respectively shown. The intermediate support assembly 100 is used to support the truss 10 (such as Figure 3 As shown), it is particularly used for supporting a long-span escalator 1, wherein for the long-span escalator 1, the supporting length is usually greater than 10m.
[0044] The intermediate support assembly 100 primarily comprises a support member 110 and a support plate 120. The support member 110 comprises two support portions 112, a crossbeam 114, a first leg 115, and a second leg 116. The two support portions 112 are respectively used to support the trusses 10 on either side of the escalator 1. The crossbeam 114 is connected between the two support portions 112. The first leg 115 and the second leg 116 extend downward from either side of the crossbeam 114. The two support plates 120 are respectively disposed below the first leg 115 and the second leg 116 and are configured to support them, respectively. The support plates 120 are stationary (i.e., fixed relative to the building or the ground).
[0045] According to the above arrangement, the intermediate support assembly 100 supports the first leg 115 and the second leg 116 via the support plate 120. The first leg 115 and the second leg 116 then support the crossbeam 114. The crossbeam 114 then supports the two support portions 112. Finally, the two support portions 112 support the trusses 10 on both sides of the escalator 1. However, in this arrangement, the intermediate support assembly 100 can only support the trusses 10 on both sides of the escalator 1 in the vertical direction and cannot restrict the movement of the trusses 10 in the lateral direction. In the event of an earthquake, if the trusses 10 are not securely fixed in the lateral direction, they are likely to be damaged due to the violent lateral swaying, causing the escalator 1 to collapse.
[0046] In order to improve the above-mentioned defects in the prior art, the intermediate support assembly 100 further includes a first reinforcement 130 and a second reinforcement 131. The first reinforcement 130 and the second reinforcement 131 can be respectively arranged on one side of the first leg 115 and the second leg 116 away from the corresponding truss 10. For example, the first reinforcement 130 for supporting the left truss 10 is arranged on the right side of the first leg 115, and the second reinforcement 131 for supporting the right truss 10 is arranged on the left side of the second leg 116. The first reinforcement 130 is arranged along the first direction (for example, Figure 1 The second reinforcement member 131 is abutted against the first leg portion 115 in the second direction (eg, Figure 1The first reinforcement 130 and the second reinforcement 131 are respectively fixed to the corresponding support plates 120 (alternatively, the first reinforcement 130 and the second reinforcement 131 can also be formed integrally with the corresponding support plates 120). The first reinforcement 130 can limit the rightward movement of the first leg 115, thereby limiting the rightward movement of the truss 10. The second reinforcement 131 can limit the leftward movement of the second leg 116, thereby limiting the leftward movement of the truss 10. By providing the first reinforcement 130 and the second reinforcement 131, the displacement of the truss 10 in the left and right directions of the intermediate support assembly 100 is limited, thereby avoiding the truss 10 from swinging significantly in the middle section in the length direction of the escalator 1, thereby improving the seismic performance of the escalator 1.
[0047] Preferably, the first reinforcement member 130 and / or the second reinforcement member 131 may have a horizontal portion 132 and a vertical portion 133. The horizontal portion 132 extends in a horizontal plane and is fixed to the corresponding support plate 120, and the vertical portion 133 extends in a vertical plane and abuts against the corresponding leg 115, 116. The horizontal portion 132 is used to provide vertical support for the first reinforcement member 130 and / or the second reinforcement member 131, and the vertical portion 133 is used to limit the lateral movement of the first leg 115 and the second leg 116, thereby limiting the lateral movement of the truss 10.
[0048] Preferably, the first reinforcement member 130 and / or the second reinforcement member 131 may further include a reinforcement plate 134 having a horizontal edge 135, a vertical edge 136, and a beveled edge 137. The horizontal edge 135 contacts the horizontal portion 132, the vertical edge 136 contacts the vertical portion 133, and the beveled edge 137 is connected between the ends of the horizontal edge 135 and the ends of the vertical edge 136. The reinforcement plate 134 can increase the strength of the first reinforcement member 130 and / or the second reinforcement member 131, making the first reinforcement member 130 and / or the second reinforcement member 131 more reliably abutting against the first leg 115 and / or the second leg 116, thereby limiting the left-right displacement of the truss 10 in the intermediate support assembly 100, preventing the truss 10 from swinging significantly in the middle section of the escalator 1 in the longitudinal direction, and further improving the seismic performance of the escalator 1. In addition, the reinforcing plate 134 may be provided with a hole extending in a direction perpendicular to the surface of the reinforcing plate 134 , so that the operator can conveniently carry the reinforcing plate 134 through the hole when installing the intermediate support assembly 100 .
[0049] Preferably, the intermediate support assembly 100 may further include two intermediate plates 140, each disposed between the corresponding legs 115, 116 and the corresponding support plate 120 and secured to the corresponding legs 115, 116. The surfaces of the intermediate plates 140 facing the support plate 120 are formed from a low-friction material (e.g., polytetrafluoroethylene, stainless steel, copper alloy, etc.). Due to the low friction between the intermediate plates 140 and the support plate 120, the support plate 120 does not restrict the movement of the intermediate plates 140 along the travel direction of the escalator 1, and thus does not restrict the movement of the truss 10 along the travel direction of the escalator 1. The intermediate support assembly 100 restricts the freedom of movement of the truss 10 in the lateral direction, but does not restrict the freedom of movement of the truss 10 in the travel direction of the escalator 1. This contributes to the structural stability of the truss 10 in the event of an earthquake.
[0050] Optionally, the first leg 115 and the second leg 116 are connected to the two intermediate plates 140 via bolts, with any number of bolts. Blind holes (not shown) are provided in the intermediate plates 140 in the direction corresponding to the first leg 115 or the second leg 116, for receiving and securing the bolts. The bolts thereby generate compressive stress on the intermediate plates 140 and the support plates 120 below them, further enhancing the structural stability of the truss 10 during earthquakes.
[0051] This document describes in detail several exemplary embodiments of the present invention with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and the various technical features and structures proposed in the present invention may also be combined without exceeding the scope of protection of the present invention, which is determined by the appended claims.
