Description

Technical Field

[0001] The utility model relates to the technical field of escalators or moving walkways, in particular to an earthquake-resistant and wind-resistant non-fixed intermediate supporting structure of escalators or moving walkways. Background Art

[0002] When the horizontal span of an escalator or moving walkway reaches a certain distance, an intermediate support structure needs to be added in the middle of the escalator or moving walkway to support the escalator or moving walkway.

[0003] In the prior art, in the specific design of the intermediate support structure of escalators and moving walkways, the intermediate support structure plays the role of supporting the truss and adjusting the vertical height of the truss. In addition, considering the factors of earthquake and wind load, it is necessary to limit the lateral displacement of the intermediate support structure to prevent the truss from swinging left and right under the action of earthquake or wind load to cause additional damage to passengers, and at the same time, it is necessary to adapt to the requirements of the longitudinal "inter-story displacement" of buildings in earthquakes or different countries and regions.

[0004] A Chinese utility model patent application numbered CN201220477855.X discloses a technical solution for an intermediate support device for earthquake protection or expansion joint spanning on an escalator or moving walkway. In this technical solution, the intermediate support device cannot slide longitudinally and cannot adapt to the longitudinal "inter-layer displacement".

[0005] The invention patent with application number CN201580017149.3 discloses a technical solution for lateral damping and intermediate support for escalators and moving walkways in earthquake events. The advantage of this technical solution is that it uses a damping device, but allows the truss to move laterally, that is, the truss is allowed to move and shake laterally under the action of an earthquake, which may cause passengers to fall and cause additional injuries to passengers.

[0026] 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.

[0027] like Figure 1-4 The figure shows a non-fixed intermediate support structure for earthquake and wind load resistance of an escalator or a moving walkway described in this embodiment. The non-fixed intermediate support structure can support the trusses of the escalator or the moving walkway. The non-fixed intermediate support structure is installed on a pre-embedded steel plate 1. The pre-embedded steel plate 1 has two extension directions, the transverse direction and the longitudinal direction, on the horizontal plane. The transverse direction is the width direction of the moving walkway or the escalator, and the longitudinal direction is the projection direction of the length direction of the moving walkway or the escalator on the horizontal plane. In this embodiment, two groups of non-fixed intermediate support structures are arranged relatively spaced apart in the transverse direction of the pre-embedded steel plate 1.

[0028] The non-fixed intermediate support structure includes components or assemblies such as a rubber pad 2, a bottom plate 3, an adjustment support plate 5, an interlaced pad 4, a first limit assembly, and a second limit assembly. The rubber pad 2 is placed on the embedded steel plate 1. The bottom plate 3 is stacked on the top surface of the rubber pad 2. The adjustment support plate 5 is movably arranged above the bottom plate 3, and an upper and lower gap is formed between the two. A plurality of adjustment bolts 6 are threadedly connected to the adjustment support plate 5. The adjustment bolt 6 has an adjustment state of abutting against the bottom plate 3. In this adjustment state, the adjustment bolt 6 is screwed so that the adjustment support plate 5 moves up and down relative to the bottom plate 3, so that the size of the upper and lower gaps can be adjusted. The thickness of the interlaced pad 4 is adapted to the upper and lower gaps, and has an interlaced state inserted in the adjustment gap. In this interlaced state, the interlaced pad 4 abuts between the bottom plate 3 and the adjustment support plate 5 up and down, thereby supporting the adjustment support plate 5. The interlaced pad in this embodiment includes a plurality of combinations arranged in an upper and lower stack. The assembly is a thin sheet structure. By increasing or decreasing the number of the assembly, the overall thickness of the interleaved pad can be changed, so that the size of the upper and lower gaps can be adapted. The interleaved pad 4 is made of rubber. After the interleaved pad 4 forms an interleaved state, the adjusting bolt 6 is reversely screwed so that the adjusting bolt 6 is in a loose state of being separated from the bottom plate 3 or the adjusting support plate 5, so that the adjusting support plate 5 is completely supported by the interleaved pad 4.

[0029] In this embodiment, the above-mentioned assembly is processed with an avoidance groove. When the inserting pad 4 is inserted into the upper and lower gaps, the position of the adjusting thread is avoided through the avoidance groove.

[0030] The above-mentioned adjustment support plate 5 is fixedly connected with an intermediate support column 9, which is connected to the truss to support the truss. The above-mentioned first limit assembly is fixedly installed on the embedded steel plate 1, and is used to limit the adjustment support plate 5 from moving in the lateral direction, and allow the adjustment support plate 5 to move in the longitudinal direction. Through the limitation of the first limit assembly, the truss cannot move in the lateral direction, but can move in the longitudinal direction. Specifically, the intermediate support columns 9 of the above-mentioned two groups of non-fixed intermediate support structures are rigidly connected by a crossbeam, so that the two groups of non-fixed intermediate support structures form a whole. The above-mentioned first limit assembly includes two first limit members 7 arranged on the relative outer side or the relative inner side of the two groups of non-fixed intermediate support structures. The first limit member 7 forms a limit fit with the side of the adjustment support plate 5. The above-mentioned two first limit members 7 cooperate with each other, so as to limit the movement of the two groups of non-fixed intermediate support structures in the lateral direction. Among them, the first limit member 7 synchronously forms a limit fit with the rubber pad 2, the bottom plate 3 and the interlaced pad 4 in the lateral direction. The first limiting member 7 is made of angle steel and is fixed on the embedded steel plate 1 by welding.

[0031] The above-mentioned second limiting assembly is arranged on the embedded steel plate 1, and the above-mentioned second limiting assembly or the second limiting assembly cooperates with the first limiting assembly to limit the movement of the rubber pad 2, the bottom plate 3, and the interlaced pad 4 in the horizontal and vertical directions. Specifically, the above-mentioned rubber pad 2, the bottom plate 3, and the interlaced pad 4 are all square structures with four vertex angles. The second limiting assembly includes an L-shaped second limiting member 8. The second limiting member 8 is arranged corresponding to a number of vertex angles. The second limiting member 8 is installed on the outside of the vertex angles of the rubber pad 2, the bottom plate 3, and the interlaced pad 4, and the two side edges of the second limiting member 8 form a limiting match with the two side surfaces of the vertex angles of the rubber pad 2, the bottom plate 3, and the interlaced pad 4. In this embodiment, since the above-mentioned first limiting member 7 has limited the rubber pad 2, the bottom plate 3, and the interlaced pad 4, the number of the second limiting members 8 here can be two, so as to achieve the above-mentioned limiting effect. In addition, according to actual needs, the number of the second limiting members 8 can also be three or four. The second limiter 8 is made of angle steel. The second limiter 8 is welded and fixed to the embedded steel plate 1. Through the above structural design, the first limiter assembly and the second limiter assembly cooperate with each other to limit the rubber pad 2, the bottom plate 3, and the interlaced pad 4 in the horizontal and vertical directions, and prevent the rubber pad 2, the bottom plate 3, and the interlaced pad 4 from moving apart from each other when the support plate 5 is adjusted to move in the longitudinal direction, which effectively improves the stability of the overall structure and has strong practicality.

[0032] In this embodiment, the rubber pad 2 is used to reduce the impact of the vibration of the escalator or moving walkway on the building, and can also play a role in partial shock absorption and vibration isolation during an earthquake.

[0033] When used specifically, by screwing the adjusting bolt 6, the bottom plate 3 holds the adjusting bolt 6 to change the size of the upper and lower gaps between the bottom plate 3 and the adjusting support plate 5, thereby realizing the adjustment of the upper and lower heights of the intermediate support column 9 and the truss. After the adjustment is in place, a number of assemblies are stacked to form an interlaced pad 4 of a certain thickness, and the number of assemblies is determined according to the size of the upper and lower gaps. The interlaced pad 4 is inserted into the upper and lower gaps between the bottom plate 3 and the adjusting support plate 5. Finally, the adjusting bolt 6 is screwed in the opposite direction to loosen or directly disassemble the adjusting bolt 6 to complete the height adjustment of the non-fixed intermediate support structure. After the above adjustment is completed, the first limiter 7 is welded to the embedded steel plate 1 to limit the lateral movement of the adjusting support plate 5, thereby limiting the lateral movement of the truss. Finally, the second limiter 8 is welded to the embedded steel plate 1 to limit the lateral and longitudinal positioning of the rubber pad 2, the bottom plate 3 and the interlaced pad 4. In the above manner, the adjustment support plate 5 can be restricted from moving in the lateral direction and allowed to move in the longitudinal direction, thereby restricting the truss from moving in the lateral direction and realizing the longitudinal movement of the truss, and resisting earthquakes and wind loads, avoiding the lateral shaking of the truss, and affecting the safety of the truss rigidity and strength, so as to effectively meet the earthquake and wind load resistance needs of escalators or moving walkways, and meet the "inter-story displacement" requirements of buildings in different countries and regions. At the same time, when there is no wind load and no earthquake resistance is required, the non-fixed intermediate support structure can also meet the installation requirements of expansion joints across buildings (set to prevent buildings from thermal expansion and contraction due to climate temperature changes).

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
