[0021] Figure 1 A perspective view of an escalator installation module according to an embodiment of the present disclosure is shown. As Figure 1 shown, the escalator installation module includes a module bracket for mounting to a truss (not shown) of the escalator. The truss of the escalator is a bracket embedded in a building. During the modernization of an old escalator, the truss of the old escalator is usually retained, and an escalator installation module is provided for replacement and modernization. The module bracket includes an upper module bracket (not shown) located at the upper part of the escalator and a lower module bracket 160 located at the lower part of the escalator. Figure 1 Only the lower module bracket 160 is shown.

[0022] Figure 2 A perspective view of a handrail tensioning device according to an embodiment of the present disclosure is shown, and Figure 3 Another perspective view of a handrail tensioning device according to an embodiment of the present disclosure is shown.

[0023] As Figures 1-3As shown, the handrail belt tensioning device includes a mounting bracket 110, a connecting bracket 120, a pressure wheel 150, an adjusting bolt 130, and a sliding guide 140. In an embodiment of the present disclosure, the handrail belt tensioning device is fixed to the module bracket through the mounting bracket 110 (i.e., the mounting interface), rather than directly fixed to the truss. The position of the handrail belt tensioning device is fixed relative to other functional components such as the driving device and the skirt plate 170 that are also mounted on the module bracket. Therefore, the handrail belt tensioning device does not need to be adaptively modified and adjusted according to the size and structure of the truss of the old escalator, but can directly cooperate well with these functional components. Installation time and cost are saved.

[0024] As Figure 2 and Figure 3 shown, the mounting bracket 110 includes a mounting bracket body and a nut block fixed to the mounting bracket body. The mounting bracket body includes a transverse plate 111 and mounting legs 112 extending from the transverse plate 111, and mounting feet 113 are located at the free ends of the mounting legs 112. In this embodiment, as Figure 1 shown, the mounting bracket 110 is fixed to the bent portion of the lower module bracket 160 at the mounting feet 113. The connecting bracket 120 is connected to the mounting bracket 110 such that the connecting bracket 120 can move relative to the mounting bracket 110 in the vertical direction. The pressure wheel 150 is mounted on the connecting bracket 120 and thus moves in the vertical direction together with the connecting bracket 120. The pressure wheel 150 is used to cooperate with the handrail belt to adjust the tension of the handrail belt.

[0025] The connecting bracket 120 includes a plate-shaped main body 121, an L-shaped tab 122 fixed to the plate-shaped main body 121, and a guide groove 123 provided in the plate-shaped main body 121. The sliding guide 140 cooperates with the guide groove 123 to guide the vertical movement of the connecting bracket 120 relative to the mounting bracket 110. For example, the sliding guide 140 includes a bolt fixed to the mounting bracket body, which extends through the guide groove 123. Therefore, the connecting bracket 120 can smoothly move relative to the mounting bracket 110 in the vertical direction. The adjusting bolt 130 has an adjusting head 131 and a rod portion 132. By operating the adjusting head 131 of the adjusting bolt 130 to twist the adjusting bolt 130, the connecting bracket 120 moves relative to the mounting bracket 110 in the vertical direction. In this embodiment, the rod portion 132 of the adjusting bolt 130 passes through an opening in the tab 122 and is threadedly connected to a threaded block. One end side of the adjusting head 131 abuts against the tab 122 on one side of the tab 122. A stopper is provided on the other side of the tab 122 such that the adjusting bolt 130 can rotate relative to the tab 122 but cannot translate. The adjusting bolt 130, the connecting bracket 120, and the mounting bracket 110 may also have other configurations, and the present disclosure is not limited thereto.

[0026] In an embodiment of the present disclosure, the adjusting head 131 of the adjusting bolt 130 and the mounting foot 113 of the mounting bracket 110 are disposed at opposite ends of the handrail tensioning device in the vertical direction. The mounting leg 112 extends away from the adjusting head 131, and the mounting foot 113 is disposed at one end of the mounting leg 112 away from the adjusting head 131. The adjusting head 131 of the adjusting bolt 130 and the pressing wheel 150 are disposed at opposite ends of the connecting bracket 120 in the vertical direction. Therefore, when the handrail tensioning device is mounted to the module bracket via the mounting foot 113, the adjusting head 131 can extend vertically upward to a position accessible by maintenance personnel.

[0027] Figure 4 FIG. shows a partial perspective view of an escalator equipped with a handrail tensioning device according to an embodiment of the present disclosure, in which the cover plate is removed to show a part of the handrail tensioning device. As Figure 4 shown, the side skirt plate 170 and the upper cover plate are disposed on both sides of the steps 180 of the escalator. The handrail tensioning device is disposed on the side of the skirt plate 170 away from the steps 180 and below the cover plate. The adjusting head 131 extends vertically upward to a position directly adjacent to the cover plate. That is, there are no other components between the adjusting head 131 and the cover plate. Therefore, after removing the cover plate, the tension of the handrail can be adjusted by operating the adjusting head 131 of the adjusting bolt 130 without disassembling the steps 180, etc. Therefore, the maintenance of the escalator is simpler and more convenient.

[0028] The scope of the present disclosure is not limited by the embodiments described above, but is defined by the appended claims and their equivalent scope.
