The escalator is provided with a circulating ladder path to transport people. In recent years, according to the needs of development, escalators in shopping malls, stations and airports are being reformed in terms of escalator performance and energy saving, and the old escalators are renovated. Usually, when the old escalator is renovated, the old escalator parts are removed, but the truss of the escalator is kept. Then, the technicians install new escalator components, such as the upper escalator module and the lower escalator module, on site.
For modern escalators, trusses and escalator modules are usually assembled in advance in the factory and installed directly at the site. However, for the old elevator reconstruction project, because the space frame of the original escalator installation site has been limited, new escalator modules can only be installed on the existing truss. The solution in the prior art is to disassemble the elevator module into a plurality of small parts, bring these disassembled small parts to the reconstruction site, and assemble them on site, which is time-consuming and costly to install and debug.
Multifunctional connecting bracket, also known as multifunctional connecting plate or multifunctional interface plate, usually needs to be connected with the truss in the prior art for connecting functional components (such as comb plate, skirt plate, cover plate or entrance panel) to the truss.
Aiming at the defects of the prior art, the present disclosure provides a pre-assembled escalator module and an escalator including the pre-assembled escalator module. Next, a pre-assembled escalator module and a preferred embodiment of an escalator according to the present disclosure will be described in detail with reference to the drawings.
Compared with the embodiment shown in the drawings, the feasible embodiments within the protection scope of this disclosure may have fewer components, other components not shown in the drawings, different components, components arranged differently or components connected differently, etc. Furthermore, two or more components in the drawings may be implemented in a single component or a single component shown in the drawings may be implemented as a plurality of separate components without departing from the concept of the present disclosure.
It should be noted that in order to simplify the description, the embodiment of this disclosure will highlight the main components of the pre-assembled escalator module, and omit the description of other conventional components in the escalator, including but not limited to: truss, step ladder path, spindle drive assembly, handrail belt drive wheel assembly, guide wheel assembly, etc.
A pre-assembled escalator module according to at least one embodiment of the present disclosure will be described with reference to the drawings. It should be noted that the pre-assembled escalator module proposed in this disclosure can be the upper escalator module and/or the lower escalator module of an escalator. For the sake of simplicity, the embodiment of this disclosure will be described below mainly by taking the upper escalator module as an example. Those skilled in the art can refer to the characteristics of the upper escalator module and apply similar or identical features to the lower escalator module.
As shown in fig. 1, a pre-assembled escalator module 10 according to at least one embodiment of the present disclosure includes a module side plate 1, a truss interface 101, a multifunctional connecting bracket 2, a comb plate 3, a skirt plate 4, a cover plate 5 and an entrance panel 6. The comb plate 3, skirt plate 4, cover plate 5 and entrance panel 6 can be collectively referred to as functional components, which are used to realize some functions of the escalator or for decoration. For the purpose of this disclosure, the multifunctional connecting bracket 2 is connected to the module side plate 1, and functional components are connected to the module side plate 1 through the multifunctional connecting bracket 2. This is different from the traditional multifunctional connecting bracket, which needs to be connected to the truss. However, in the modernization of the old escalator , the truss is located at the site, so the multifunctional connecting bracket can only be installed at the site, and then the functional components can be connected to the multifunctional connecting bracket.
On the other hand, in the technical scheme disclosed in this disclosure, the multifunctional connecting bracket 2 is connected with the module side plate 1, and thus functional components can be connected with the module side plate 1 by connecting to the multifunctional connecting bracket 2, which allows for greatly improving the integration of the escalator module, realizing the pre-assembly of the escalator module in the factory, saving the time-consuming of on-site installation and debugging, reducing the installation error caused by on-site installation and improving the assembly accuracy.
In addition, fig. 1 also shows a truss interface 101 arranged at an end of the pre-assembled escalator module 10 for connecting the pre-assembled escalator module 10 to the truss. As shown in fig. 1, truss interfaces 101 can be provided at four locations along both ends in the horizontal direction and two sides in the lateral direction, which are used for hoisting the pre-assembled escalator module 10 to the truss on site and then installing and connecting it to the truss.
Fig. 2 shows a perspective view of a pre-assembled escalator module 10 with functional components omitted, which shows a module side plate 1 and a multifunctional connecting bracket 2. As shown in figs. 15 and 16, the multifunctional connecting bracket 2 may include a first bracket 201 along the horizontal direction and a second bracket 202 inclined relative to the horizontal direction, and the skirt plate 4 and/or the cover plate 5 are both connected to the first bracket 201 and the second bracket 202. The comb plate 3 and the entrance panel 6 may be connected to the first bracket 201. For the upper escalator module, it is necessary to connect the guide wheel assembly of the handrail belt and guide the handrail belt horizontally and obliquely, so it is necessary to provide two brackets. For the lower escalator module, only one bracket is needed.
Illustratively, figs. 3 to 7 show the connection of the comb plate 3 to the pre-assembled escalator module 10 according to at least one embodiment of the present disclosure. As shown in figs. 3 and 4, and with additional reference to fig. 15, the multifunctional connecting bracket 2 may include a support plate 21, on which a plurality of mounting interfaces for mounting functional components, such as a plurality of C-shaped plates 23, a second profile piece 24 and a connecting bracket 25 connected with the support plate 21, are provided.

The adjusting screw assembly 7 may specifically include a long screw 71 and an adjusting screw 72, wherein the adjusting screw 72 has a through hole and an external thread, and the adjusting screw 72 is connected to the comb plate 3 through the external thread, and the long screw 71 is threaded with the threaded plate 22 through the through hole. A gasket 8 may also be provided between the support plate 21 and the threaded plate 22.
The adjustment of the installation height of the comb plate 3 is important, which is related to the tightness between the steps and the comb plate 3. Therefore, it is necessary to provide components that can adjust the installation height of the comb plate 3.
The length of the adjusting screw 72 can be customized, for example, there can be a plurality of adjusting screws 72 with different lengths. One end of the adjusting screw 72 supports the nut of the long screw 71, and the other end directly abuts against the gasket 8. The installation height of the comb plate 3 can be adjusted by adjusting screws 72 and gaskets 8 with different lengths. It is only necessary to replace the adjusting screws 72 with different lengths or the thickness and quantity of gaskets 8, without replacing the new comb plate 3 or the support plate 21. Thus the installation and debugging process is simple.
Alternatively, the end of the adjusting screw 72 may be directly abutted against the support plate 21 without providing the gasket 8.
Illustratively, figs. 8 to 10 show the connection of the skirt plate 4 to the pre-assembled escalator module 10 according to at least one embodiment of the present disclosure.
