Description

Technical Field

[0001] This invention relates to the technical field of escalators and moving walkways, and in particular to an integrated module for the retrofitting of escalator retaining trusses. Background Technology

[0002] The assemblies, handrails, skirt panels, and decorative components such as glass on escalators all require high positioning and installation accuracy as well as convenient adjustment space. One of the biggest challenges in the retrofitting of escalator retaining trusses is the large variety of components required, their diverse functions, complex assembly processes, and numerous installation steps. This difficulty affects the efficiency and progress of the retrofit, and makes it difficult to control the positioning and installation accuracy and the quality of the retrofit. Therefore, this invention provides an integrated module for the retrofitting of escalator retaining trusses to solve the above-mentioned problems.

[0003] Currently, in the field of escalator truss renovation, there are two main renovation modes: component assembly and overall embedding. The overall embedding mode is often limited by factors such as construction space, hoisting volume and weight, and insufficient internal space of the original truss, resulting in significant limitations. Therefore, the component assembly mode is more widely applicable and versatile. In the component assembly mode, processes such as adding supporting structural components, assembly connection and adjustment, handrail positioning and adjustment, skirt panel positioning and connection, and glass positioning and clamping generally need to be carried out independently step by step. The components that achieve these functions are mostly individual parts, requiring assembly into the original truss, individual positioning and adjustment, and multiple coupling adjustments with the new escalator system, handrail system, and decoration system to meet the installation and adjustment requirements.

[0029] The aforementioned sub-modules each perform independent functions such as positioning, connection, and adjustment. When combined and assembled, they constitute the integrated module described in this invention. This integrated module requires only one positioning step during on-site installation to complete the installation of the aforementioned devices and achieve the various functions described above.

[0030] The installation method of this invention for the modification of escalator retaining trusses is as follows: Step 1: Remove all components from the old truss.

[0031] Before modifying the escalator truss, all components of the old truss must be removed, including handrails, skirt panels, glass trim, and the upper escalator assembly, while preserving the original truss structure. Care must be taken during dismantling to protect the original truss from damage and ensure its structural integrity, providing a solid foundation for subsequent module installation.

[0032] Step two: Securely connect the integrated module for the escalator truss renovation to the old truss body.

[0033] The integrated module of this invention for retrofitting escalator retaining trusses is fixedly connected to the old truss body. During connection, it is essential to ensure a secure bond between the support sub-module and the old truss. This step is fundamental to the entire retrofit process, as the stability of the connection directly affects the subsequent safe operation of the escalator.

[0034] Step 3: Position and install the escalator assembly using the upper assembly connection and adjustment sub-module.

[0035] The escalator upper assembly connection and adjustment submodule of this invention is used to install the escalator upper assembly into place. During installation, the upper assembly can be precisely adjusted in three dimensions using the assembly up-down adjustment bolt assembly, assembly front-back adjustment bolt assembly, and assembly left-right adjustment bolt assembly, ensuring the accurate positioning of the upper assembly and guaranteeing the smooth operation of the escalator.

[0036] Step four: Position and adjust the handrail using the handrail positioning and adjustment sub-module.

[0037] First, place the handrail belt on the handrail roller assembly, and ensure its correct position using the handrail belt guide assembly. Then, adjust the tension of the handrail belt using the handrail belt tensioning device to ensure that the handrail belt does not become too loose or too tight during operation. During adjustment, the position of the handrail roller mounting plate can be fine-tuned using the screw assembly, thereby achieving precise control of the handrail belt tension.

[0038] Step 5: Position and adjust the apron board using the apron board positioning and connection sub-module.

[0039] Connect the apron board to the apron board connecting bracket. Adjust the front-to-back, height, and left-to-right position of the apron board using the fixing bolt assembly, ensuring an appropriate gap between the apron board and the footboard to prevent squeezing or jamming accidents. After adjustment, tighten all connecting bolts to ensure the apron board is securely installed.

[0040] Step six: Position and adjust the glass using the glass positioning and clamping sub-module.

[0041] Place the glass decorative piece into the glass retainer assembly, and adjust the position of the glass using the glass retainer fixing bolt assembly to ensure that the glass decorative piece is installed flat and securely. During adjustment, ensure that the glass retainer provides sufficient clamping force to prevent the glass from loosening or falling off during escalator operation.

[0042] The above six steps complete the entire process of modifying the escalator by retaining its truss. This installation method fully utilizes the advantages of integrated modules, simplifies the installation process, improves installation efficiency, and ensures the safety and stability of the modified escalator.

[0043] The above description is only a preferred embodiment of the present invention, and the structure, location, and functional implementation of the integrated module can all take different forms. Furthermore, this integrated module can also be applied to other forms of modification and the installation and manufacture of new elevators.
