[0002] The frame on an escalator is the part that supports the floor slab, such as Figure 1 The figure shows a frame structure of the prior art. The support and height adjustment of the frame are achieved by supporting bolts fixed on the trusses. The rubber pads penetrate through the grooves on the frame and support the floor slabs, playing a role of shock absorption. The frame is provided with drainage grooves. The floor slabs are in contact with the frame through the rubber pads, so the stress point is at the rubber pads, while the supporting bolts and the fulcrum of the frame and the stress point of the rubber pads are not in the same place, forming a lever structure, resulting in the risk of the frame turning over when stressed. The drainage grooves are arranged on the inner side of the rubber pads, and rainwater flows in through the gap between the floor slabs and the frame, separated by the rubber pads, making it difficult for the drainage grooves to achieve a better drainage effect.

[0030] 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.

[0031] like Figure 3-7The figure shows a floor plate 6 support structure of an escalator described in this embodiment. The escalator of this embodiment includes a truss 1. The floor plate 6 support structure is installed on the truss 1 so as to support the floor plate 6 of the escalator. The floor plate 6 support structure includes a support unit 2, a frame 3, and a floor plate 6. Among them, a plurality of groups of support units 2 are arranged on opposite sides of the truss 1 and are arranged at intervals along the length direction of the truss 1. The support unit 2 includes a connector 21, a support plate 22, and a fastening assembly 5. The connector 21 is fixed on the truss 1, and the support plate 22 is arranged horizontally and fixed on the connector 21. A perforation 221 is processed on the support plate 22. Among them, the above-mentioned connector 21 is a rod-shaped structure, and a threaded section is processed on it. The connector 21 is inserted into the truss 1 movably up and down. Adjustment nuts 23 are threadedly connected to the connector 21 on the upper and lower sides of the truss 1. By screwing the adjusting nut 23, the vertical height of the connecting member 21 can be adjusted, and the connecting member 21 is locked, so that the vertical height of the connecting member 21 can be adjusted. In this embodiment, one end of the connecting member 21 is welded to the supporting plate 22.

[0032] The aforementioned enclosure 3 is installed above the support unit 2. The enclosure 3 is a frame structure made of aluminum alloy. The enclosure 3 includes two frame edges arranged opposite to each other in the width direction of the truss 1. The frame edge extends along the length direction of the truss 1 and is supported on the support plates 22 of several groups of support units 2 on the corresponding side. The frame edge includes a bottom plate 31 and side plates 32 fixed to the bottom plate 31. The bottom plate 31 and the side plates 32 are integrally formed, and the two are combined to form an L-shaped structure. The side plates 32 are located on the relatively outer side of the bottom plate 31, and the floor plate 6 is supported on the bottom plate 31 so that it can be limited by the side plates 32 on both sides in the width direction of the truss 1.

[0033] When designing the specific structure, a drainage groove 311 is processed on the top surface of the bottom plate 31. An inverted T-shaped groove 312 is processed on the top surface of the bottom plate 31. The above-mentioned drainage groove 311 and inverted T-shaped groove 312 both extend along the length direction of the frame edge. A rubber member 4 is arranged between the bottom plate 31 and the floor plate 6. The rubber member 4 is inserted into the inverted T-shaped groove 312 along the length direction of the inverted T-shaped groove 312, and has a contact end exposed above the top surface of the bottom plate 31. The floor plate 6 contacts the rubber member 4 to play a role in buffering and shock absorption. The drainage groove 311 is arranged on one side of the rubber member 4 close to the side plate 32. Through the above-mentioned structural design, when rainwater enters through the gap between the floor plate 6 and the side plate 32, the rainwater first enters the drainage groove 311, so that it can be guided and discharged by the drainage groove 311.

[0034] A slide groove 313 is processed on the bottom surface of the aforementioned bottom plate 31 corresponding to the perforation 221. The slide groove 313 is a T-shaped groove, and the slide groove 313 extends along the length direction of the frame edge. Among them, the aforementioned fastening assembly 5 includes a fastening bolt 51 and a matching nut 52. The fastening bolt 51 is adapted to the slide groove 313 so as to be slidably installed in the slide groove 313. The fastening bolt 51 of this embodiment is a T-shaped bolt. The T-shaped bolt has a head and a rod body, and a threaded section is processed on the rod body. The head of the T-shaped bolt can be inserted into the T-shaped groove from one end of the frame edge and slide in the T-shaped groove. The fastening bolt 51 has an assembly state of being inserted into the perforation 221 on the support plate 22 at the corresponding position. In this assembly state, the matching nut 52 is used to cooperate with the fastening bolt 51 to lock the frame edge and the support plate 22. Through the above-mentioned structural design, the fastening bolt 51 can slide in the slide groove 313 and adjust the position so as to be able to be inserted with the perforation 221 on the support plate 22. There is no need to drill holes on the frame 3 for assembly, which saves labor costs and reduces the requirements for the drilling positions on the truss 1 and the overall assembly accuracy. The overall structure is easy to assemble, saves time and effort, and effectively meets the assembly requirements of the floor slab 6.

[0035] In this embodiment, the aforementioned through hole 221 is a waist-shaped hole; the length of the waist-shaped hole extends along the width direction of the truss 1, so that the length direction of the waist-shaped hole and the extension direction of the slide groove 313 are perpendicular to each other on the horizontal plane. Through the above structural design, the fastening bolt 51 can be smoothly inserted into the through hole 221, and the position accuracy requirement of the through hole 221 is reduced.

[0036] During specific assembly, several support units 2 are fixed on the truss 1, and several fastening bolts 51 are pre-inserted into the slide grooves 313 on the enclosure 3. The enclosure 3 is placed on the support plates 22 of each group of support units 2. During the placement process, the position of the fastening bolts 51 in the slide grooves 313 is adjusted to insert the fastening bolts 51 into the through holes 221 of the support plates 22 at the corresponding positions, and then the matching nuts 52 are screwed into the fastening bolts 51 and locked. Then the floor plate 6 is placed on the enclosure 3 and locked with screws. By screwing the adjusting nuts 23, the height of the connecting member 21 on the truss 1 is adjusted, thereby realizing the position adjustment of the floor plate 6 and the enclosure 3 in the height direction. In the above manner, a plane support is formed between the frame edge of the enclosure 3 and the support plate 22, which can stably support the enclosure 3 and balance the force, effectively solving the problem of external folding caused by unreasonable force on the outer frame. The drainage groove 311 is arranged on the outside of the rubber member 4, and rainwater is not blocked by the rubber member 4. The position of the drainage groove 311 is reasonably designed, which can effectively improve the drainage effect. The fastening bolt 51 can slide in the slide groove 313 and adjust the position so that it can be inserted with the through hole 221 on the support plate 22. There is no need to punch holes on the frame 3 for assembly, which saves labor costs and reduces the requirements for the punching position on the truss 1 and the overall assembly accuracy.
