Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 7, a step chain waterproof device 10 according to an embodiment of the present application is configured to be installed and shielded above a step chain 20, where the step chain waterproof device 10 includes at least two waterproof components 11, and the at least two waterproof components 11 are connected along an extending direction of the step chain 20.

Illustratively, the flashing assembly 11 includes a pressure rail 111, a mounting unit 112, a flashing 113, and a support unit 114. The waterproof board 113 is movably arranged on the pressure rail 111 through the mounting unit 112; the supporting unit 114 is configured to have an adjustable thickness, and the supporting unit 114 is installed between the waterproof board 113 and the pressing rail 111, so that the waterproof board 113 can be adjusted in height relative to the pressing rail 111; wherein the waterproof plates 113 of two adjacent waterproof assemblies 11 are in lap joint.

In summary, implementing the technical scheme of the embodiment has the following beneficial effects: when the step chain waterproof device 10 of the above scheme is installed, the thickness of the supporting unit 114 is adjusted, so that a required relative height position can be formed between the waterproof plate 113 and the pressing rail 111, namely, under the condition that the splicing level of each section of pressing rail 111 is ensured, the heights of the waterproof plates 113 in at least two sections of waterproof assemblies 11 are arranged in a step-type height along the extending direction of the step chain 20, therefore, after each waterproof assembly 11 is assembled in a continuous mode, the waterproof plates 113 of any two adjacent sections of waterproof assemblies 11 can form overlapping installation, after rainwater drops onto the waterproof plates 113, the rainwater can flow along the waterproof plates 113, the step chain 20 is prevented from being damaged by the rainwater, and the rainwater cannot leak through the overlapping part, so that the waterproof capability of the step chain waterproof device 10 is improved. Compared with the prior art, the overlapping installation mode of the waterproof plates 113 can omit glue sealing, and has higher waterproof performance and reliability while reducing cost.

In some embodiments, the supporting unit 114 includes a spacer provided with a via hole, the spacer being disposed between the waterproof plate 113 and the pressing rail 111, and the mounting unit 112 passing through the via hole. Since the gasket itself has a certain thickness, the gasket is installed between the waterproof plate 113 and the pressing rail 111, and then the waterproof plate 113 is lifted. The spacer is machined with a via hole to facilitate the mounting unit 112 to pass through the via hole to avoid problems of mounting interference with the spacer.

Further, the gasket comprises at least two gaskets, and the at least two gaskets are arranged in a stacked manner. Along the extending direction of the step chain 20, a graded number of gaskets are sequentially installed in different waterproof assemblies 11, so that the heights of the waterproof plates 113 can form step transition, and a sequentially overlapped installation structure of the waterproof plates 113 is realized.

For example, among the plurality of waterproof assemblies 11 arranged from one end toward the other end along the extending direction of the step chain 20, the number of shims installed in each waterproof assembly 11 is six, five, four, three, two, and one in order.

In still other embodiments, at least two of the waterproof assemblies 11 are disposed obliquely in the same direction along the extending direction of the step chain 20. The rainwater dropped onto the waterproof plates 113 flows along the inclined waterproof plates 113 under the self gravitational potential energy, so that the rainwater can be prevented from leaking onto the step chain 20 below from between the two waterproof plates 113 which are adjacently overlapped.

Alternatively, as an alternative to the above embodiment, the overlapping end of one waterproof board 113 of the adjacent two waterproof assemblies 11 is provided with an overlapping recess, and the overlapping end of the other waterproof board 113 is fitted into the overlapping recess. The lap joint end is embedded in the lap joint concave part, and the formed assembly surface is a folded surface, so that a good flow blocking effect can be achieved, and therefore, excellent sealing performance is formed, and rainwater is prevented from leaking from the lap joint part.

Further, as an alternative to the above two embodiments, the step chain waterproofing device 10 further includes a sealing strip that is sealingly disposed between overlapping portions of the waterproof plates 113 of the adjacent two waterproof assemblies 11. The seal may provide a direct barrier to rain water and prevent rain water from leaking from the lap joint and dripping onto the underlying step chain 20, causing damage to the step chain 20.

With continued reference to fig. 4 and 7, in addition, the waterproof assembly 11 further includes a mounting plate 115 according to any of the above embodiments, the mounting plate 115 is fixedly disposed on one side of the waterproof plate 113 in the width direction, the mounting plate 115 is concavely provided with a notch groove recessed toward the waterproof plate 113, and the mounting unit 112 passes through the notch groove and enables the waterproof plate 113 to horizontally move left and right relative to the pressing rail 111. Therefore, the horizontal installation position of the waterproof plate 113 is convenient to flexibly adjust, so that the waterproof plate 113 can eliminate the installation dimension error and effectively shade the position right above the step chain 20.

In some embodiments, the pressing rail 111 is provided with a pressing rail 111 groove, and the mounting unit 112 is provided as a bolt unit assembled with the pressing rail 111 groove to assemble and fix the waterproof plate 113, the supporting unit 114, and the pressing rail 111. Therefore, the pressing rail 111, the supporting unit 114 and the waterproof board 113 are assembled by adopting the bolt units in a simple mode, are convenient to assemble and disassemble, and are firmly and reliably connected.

With continued reference to fig. 5, further, the step chain waterproof device 10 further includes a connecting plate 12, a first connecting member 13 and a second connecting member 14, wherein the connecting plate 12 is installed at a joint of two adjacent pressing rails 111, the first connecting member 13 is connected to the fixed connecting plate 12 and one of the pressing rails 111, and the second connecting member 14 is connected to the fixed connecting plate 12 and the other pressing rail 111. The connecting plate 12 is matched with the first connecting piece 13 and the second connecting piece 14, so that two adjacent sections of pressing rails 111 can be spliced into a whole.

Specifically, the first and second connectors 13 and 14 employ threaded members such as bolts.

In the present embodiment, the waterproof board 113 adopts a V-shaped structure, and thus the waterproof board 113 has a water guide groove 113a formed concavely. The water guide grooves 113a facilitate the collection and guiding of the rainwater flow.

With continued reference to fig. 7, further one flashing 113 at the end of the step chain flashing 10 is provided with a drain 113b. The rainwater is conveniently discharged from the water discharge port 113b in a concentrated and directional manner.

In addition, the present application provides an escalator or moving walkway 100 comprising a step chain flashing device 10 as described in any of the embodiments above.
