Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to a handrail with friction wheels and an escalator. Background Technology

[0002] The friction wheel of the handrail is a key transmission component in escalators or moving walkways. Its core function is to drive the handrail to run synchronously through friction, ensuring the stability and safety of passengers when they hold it.

[0003] However, due to the narrow interior space of the escalator truss, the friction wheel and its related components are installed in a limited area. After the inner cover of the escalator is opened, the available space for disassembling the friction wheel is small, making it inconvenient to disassemble the friction wheel. Utility Model Content

[0004] In view of this, the present invention provides a handrail with friction wheels and an escalator.

[0005] One aspect of this utility model provides a handrail friction wheel comprising: a wheel body having an outer ring body and an inner ring body, the inner ring body extending along the axial direction to form a protrusion; a transmission component disposed inside the inner ring body, the transmission component being adapted to connect with an external driving component to drive the wheel body to rotate under the drive of the external driving component; wherein, the protrusion and the transmission component are detachably connected by fasteners disposed along the radial direction of the inner ring body.

[0006] According to an embodiment of the present invention, the transmission component includes multiple connecting parts, and the multiple connecting parts are detachably connected to the protrusions by multiple fasteners.

[0007] According to an embodiment of the present invention, the transmission component further includes a main body, which has multiple ends, and the multiple ends extend into multiple connecting portions along the axial direction of the inner ring body.

[0036] Figure 1 A schematic cross-sectional view of the handrail belt friction wheel according to a related embodiment is shown.

[0037] In relevant embodiments, such as Figure 1 As shown, the handrail belt friction wheel includes a wheel body 1, a transmission component 2, and a fastener 3. The fastener 3 is positioned along the axial direction of the wheel body 1. Figure 1The wheel body 1 and the transmission component 2 are detachably connected in the horizontal direction. In this embodiment, after the handrail friction wheel is installed on the escalator, the axial space inside the escalator truss is narrow, and the operating space for maintenance personnel to use disassembly tools is relatively narrow, making it inconvenient to disassemble the friction wheel and limiting the disassembly efficiency of the escalator friction wheel.

[0038] In view of this, the present invention provides a handrail with a friction wheel, which aims to improve the disassembly efficiency of the escalator friction wheel.

[0039] Figure 2 A schematic front view of the handrail belt friction wheel according to an embodiment of the present invention is shown.

[0040] According to the present invention, the handrail belt friction wheel, such as Figure 2 As shown, the device includes a wheel body 1 and a transmission component 2. The wheel body 1 has an outer ring body 11 and an inner ring body 12, with the inner ring body 12 extending along its axial direction to form a protrusion 14. The transmission component 2 is disposed inside the inner ring body 12 and is adapted to connect with an external drive component to drive the wheel body 1 to rotate under the drive of the external drive component. The protrusion 14 and the transmission component 2 are detachably connected by fasteners 3 arranged along the radial direction of the inner ring body 12.

[0041] In one illustrative embodiment, the inner ring body 12 protrudes axially from the outer ring body 11, and the portion extending beyond the outer ring body 11 forms a protrusion 14. The protrusion 14 can be a continuous ring or a plurality of protrusions distributed on the circumference of the inner ring body 12.

[0042] In one illustrative embodiment, the inner ring 12, the outer ring 11, and the protrusion 14 can be manufactured in one piece. For example, molten metal or heated metal billet can be injected into a mold through processes such as casting or forging to obtain an integral structure having the inner ring 12, outer ring 11, and protrusion 14 in one step.

[0043] In another embodiment, the inner ring 12, outer ring 11, and protrusion 14 can be manufactured separately, and then assembled. The inner ring 12 and outer ring 11 can be fixed together by interference fit, key connection, or bolt connection. The protrusion 14 can be installed on the inner ring 12 as an independent component by welding, bolt connection, or other methods.

[0044] The external driving component can be the drive shaft of the escalator. After the transmission component 2 is connected to the drive shaft of the escalator, it transmits the power of the drive shaft to the inner ring 12, thereby driving the outer ring 11 and the handrail belt to move.

[0045] Fastener 3 can be inserted into protrusion 14 and transmission component 2. By tightening fastener 3, protrusion 14 and transmission component 2 are pressed together to form a stable connection.

[0046] In this embodiment, by extending the inner ring 12 along its axial direction to form a protrusion 14, and providing a fastener 3 along the radial direction of the inner ring 12 to detachably connect the protrusion 14 and the transmission component 2, the fastener 3 can be installed and removed from the side of the friction wheel. Inside the escalator truss, the lateral space is more open than the axial space, providing maintenance personnel with more operating space to use disassembly tools, making it easier to disassemble the friction wheel and thus improving the disassembly efficiency of the friction wheel.

[0047] According to embodiments of the present invention, such as Figure 2 As shown, the surface of the outer ring 11 is provided with a friction layer 13.

[0048] In one illustrative embodiment, the friction layer 13 may be made of, but is not limited to, rubber, polyurethane, or a composite material of rubber and glass fiber.

[0049] In this embodiment, the friction layer 13 increases the coefficient of friction with the handrail belt, preventing slippage while protecting the surface of the handrail belt from excessive wear.

[0050] According to embodiments of the present invention, such as Figure 2 As shown, the transmission component 2 may include multiple connecting parts 22, which are detachably connected to the protrusion 14 via multiple fasteners 3.

[0051] The connecting part 22 is a part on the transmission component 2 used for direct fixation to the protrusion 14. The number of connecting parts 22 can be set according to actual needs; for example, there can be 2, 3, 4, etc.

[0052] When the protrusion 14 is a continuous ring, multiple mounting points can be evenly provided on the protrusion 14 to connect with multiple connecting parts 22 respectively. When the protrusion 14 is a protrusion distributed on the circumference of the inner ring body 12, the same number of protrusions as the connecting parts 22 can be evenly provided on the circumference of the inner ring body 12 to connect with multiple connecting parts 22 respectively.

[0053] In one illustrative embodiment, the connecting portion 22 may be configured to fit against the lower surface of the protrusion 14 so that the connecting portion 22 and the protrusion 14 are tightly connected.

[0054] According to embodiments of this disclosure, the surfaces of the connecting portion 22 and the protrusion 14 facing each other may also be provided with mutually cooperating stops to facilitate the installation and positioning of the connecting portion 22 and the protrusion 14.

[0055] According to an embodiment of the present invention, by providing multiple connecting parts 22, the connection between the transmission component 2 and the protrusion 14 can be made stable and reliable.

[0056] According to embodiments of the present invention, such as Figure 2 As shown, the transmission component 2 also includes a main body 21, which has multiple ends, and the multiple ends extend into multiple connecting portions 22 along the axial direction of the inner ring 12.

[0057] Figure 3 A schematic cross-sectional view of the handrail belt friction wheel according to an embodiment of the present invention is shown.

[0058] like Figure 3 As shown, the wheel body 1 is constructed as a single-piece structure, and the cross-sectional shape of the outer ring 11, inner ring 12, and protrusion 14 is approximately L-shaped. The main body 21 and connecting part 22 of the transmission component 2 are also constructed as a single-piece structure, and the cross-sectional shape of the main body 21 and connecting part 22 is also approximately L-shaped. The protrusion 14 and connecting part 22 fit together perfectly, and the connecting part 22 and the main body 21 are pressed and fixed together by fasteners 3.

[0059] According to embodiments of the present invention, such as Figure 3 As shown, the fastener 3 may include a connecting bolt, and the connecting part 22 and the protrusion 14 are provided with a connecting hole that is connected to each other, and the connecting screw passes through the connecting hole.

[0060] Specifically, the protrusion 14 and the connecting part 22 can be provided with through holes of the same diameter. Two through holes of the same diameter are joined together to form a connecting hole. The connecting hole is provided with threads. A connecting bolt is inserted into the connecting hole to press and fix the protrusion 14 and the connecting part 22. This utility model is not limited to this.

[0061] In some embodiments, the connecting portion 22 and the protrusion 14 can also be connected by screws, such as by machining a threaded hole in the transmission component 2 and screwing the screw radially into the threaded hole from the outside of the protrusion 14. Alternatively, the connecting portion 22 and the protrusion 14 can also be connected by pins. For example, cylindrical pin holes of the same diameter can be machined in the protrusion 14 and the transmission component 2, and the cylindrical pin can be inserted radially into the pin holes to achieve the positioning and connection of the connecting portion 22 and the protrusion 14.

[0062] According to an embodiment of the present invention, the main body 21 is constructed in a generally triangular shape. Three connecting portions 22 extend axially from the three endpoints of the triangular plate along the inner ring 12, and each of the three connecting portions 22 is detachably connected to the protrusion 14 via three fasteners 3. The present invention is not limited thereto.

[0063] In some embodiments, the main body 21 may also be provided with other suitable shapes, such as a square plate shape, a circular plate shape, etc.

[0064] According to embodiments of the present invention, such as Figure 3 As shown, the main body 21 is provided with a mounting shaft hole 23, which is used to connect with an external drive component.

[0065] The mounting hole 23 can be connected to the drive component of the escalator. For example, by inserting the shaft of the drive component into the mounting hole 23, the drive component and the transmission component 2 of the friction wheel are connected as a whole, thereby realizing the transmission of power.

[0066] The size and shape of the mounting hole 23 can be precisely designed and machined according to the specifications of the output shaft of the drive component to avoid problems such as loosening and shaking during operation, and to ensure the stability and reliability of power transmission.

[0067] According to an embodiment of the present invention, a keyway is provided in the mounting shaft hole 23.

[0068] The keyway is a groove of a specific shape on the inner wall of the mounting shaft hole 23, such as a flat keyway or a semi-circular keyway.

[0069] In this embodiment, the keyway of the mounting shaft hole 23 can prevent relative rotation between the shaft of the drive component and the friction wheel transmission component 2, ensuring that the torque output by the drive component can be reliably transmitted to the transmission component 2, thereby driving the friction wheel to rotate.

[0070] This utility model also provides an escalator equipped with the aforementioned handrail with friction wheels.

[0071] By incorporating the aforementioned handrail with friction wheels into the escalator, the friction wheels can be disassembled more easily when replacement is needed, thereby improving the disassembly efficiency of the friction wheels.

[0072] The embodiments of the present invention have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of the present invention is defined by the appended claims and their equivalents.
