Description

Technical Field

[0001] This application relates to the field of elevator mechanical modification technology, and in particular to an integrated modification structure, method and automatic escalator for intermediate support and connection. Background Technology

[0002] In the current market, the demand for retrofitting escalators that have been in use for more than ten years continues to grow. Due to the long design life of truss structures and the difficulty in disassembling and hoisting them, mainstream retrofitting solutions typically only replace easily damaged components such as steps, main unit, handrails, guide rails, guardrails, and connecting bolts, while retaining the main truss structure. To minimize the impact on on-site operations, short-cycle, low-cost retrofitting solutions have become the market's preferred choice.

[0003] The existing physical separation between the connection structure and the intermediate support system has led to a concentrated exposure of the defects in the retrofit technology, mainly including the following problems:

[0004] (1) The joint needs to bear all the axial force independently, which has a redundant design problem: there are many bolts, the installation takes a long time (it needs to be hammered in), and it is difficult to ensure the tightening torque in a narrow space, which leads to a decrease in the reliability of the connection.

[0005] (2) After the main unit, guide rail and other components are updated, the intermediate support system continues to use the combination of shims and expansion bolts to adjust the vertical height and horizontal position. The adjustment accuracy of this method is poor (±2.0mm) and the process is irreversible. It is easy for the shims to loosen and cause excessive vibration during operation.

[0006] (3) More importantly, the connection and support systems need to be constructed independently, the transformation process is complex and cross-cutting, the on-site coordination cost is high, the total transformation time for a single unit is ≥10 hours (industry average), and the downtime loss is ≥12,000 yuan / unit. This transformation technology architecture is not only inefficient, but also affects the long-term operational stability of the equipment due to excessive vibration and structural redundancy, making it difficult to meet the urgent needs of commercial venues for short-cycle, low-cost transformation.

[0007] The aforementioned problems significantly impacted the renovation cycle. Therefore, how to carry out efficient renovation of escalators without replacing the trusses has become an urgent technical challenge. Summary of the Invention

[0008] Therefore, it is necessary to address the problem of local stress concentration and long renovation cycles caused by the physical separation design of the current escalator truss connection structure and intermediate support system, and to provide an integrated renovation structure, renovation method and escalator for the intermediate support and connection of the escalator.

[0009] The first aspect of this application provides an integrated modification structure for escalator intermediate support and connection, used for escalator trusses, the escalator trusses including a first truss and a second truss, comprising:

[0017] In one embodiment, the support member is provided with an adjustment hole, which is configured to extend along the length direction of the support member and is used for connecting the first truss, the second truss and the support member.

[0018] In one embodiment, the support base includes:

[0019] A support base is fixed to the surface to be installed.

[0020] A support frame is mounted on the support base and is connected to the connector;

[0021] An adjusting member is connected to the connecting member and the support frame, and the adjusting member is used to adjust the height of the connecting member relative to the surface to be installed.

[0022] In one embodiment, the bracket further includes a third connecting portion and a reinforcing portion. The third connecting portion is connected to the first connecting portion and the second connecting portion, and the third connecting portion, the first connecting portion, and the second connecting portion enclose a triangular frame. The reinforcing portion is disposed within the triangular frame.

[0023] In one embodiment, the orthographic projection of the support member in the first plane overlaps the orthographic projection of the second connection portion in the first plane.

[0024] In one embodiment, the connector includes a fourth connecting portion and a fifth connecting portion that are connected to each other and form an angle, the fourth connecting portion being connected to the support base; and the fifth connecting portion being connected to the first connecting portion.

[0025] In one embodiment, the connection component includes:

[0026] The first connector is used to overlap the upper chord of the first truss and the upper chord of the second truss; the orthographic projection of the first connector on the first plane overlaps with the orthographic projection of the support surface on the first plane.

[0027] The second connector is inclinedly disposed between the first truss and the second truss, and is connected to the upper chord of the first truss and the lower chord of the second truss.

[0028] Multiple first fasteners are used to connect the first connector to the upper chord of the first truss and the upper chord of the second truss;

[0029] Multiple second fasteners are used to connect the support member to the lower chord of the first truss and the lower chord of the second truss.

[0030] A second aspect of this application provides an escalator, comprising:

[0031] The escalator truss includes a first truss and a second truss; and

[0032] As described in the first aspect of this application, the escalator intermediate support and connecting integrated modification structure, the connecting component connects the first truss and the second truss; the support component is disposed on the surface to be installed, the support component is located upstream or downstream of the connecting component, the support component is provided with a support surface, the support surface supports and connects the first truss and the second truss, the orthographic projection of the connecting component on the first plane overlaps with the orthographic projection of the support surface on the first plane; the first plane is parallel to the support surface.

[0033] The third aspect of this application provides an integrated modification method for the intermediate support and connection of an escalator, applicable to the integrated modification structure for the intermediate support and connection of an escalator described in the first aspect of this application and the automatic escalator described in the second aspect.

[0034] Obtain data on the escalators to be modified;

[0039] This application provides an integrated retrofit structure, method, and escalator for intermediate support and connection of an escalator. The connection component of this integrated retrofit structure connects the first and second trusses of the escalator truss. The support surface of the support component supports and connects the first and second trusses. The orthographic projection of the connection component on a first plane overlaps with the orthographic projection of the support surface on the same first plane, and the first plane is parallel to the support surface. This creates surface contact between the support component and the escalator truss. When the load of the escalator truss is transferred to the support component, the load can be distributed to the support surface through a larger contact area, thereby reducing the risk of localized stress concentration in the escalator truss. Simultaneously, because the orthographic projection of the connection component on the first plane overlaps with the orthographic projection of the support surface on the same first plane, the support surface of the support component provides effective support for the connection component, reducing the risk of stress concentration in the connection area between the first and second trusses, improving the connection reliability between the connection component and the first and second trusses, and thus improving the safety and reliability of the escalator truss.

[0040] Furthermore, by combining the connecting and supporting components, the original escalator truss does not need to be replaced, and the large number of connecting plates and bolts that are traditionally placed on the sides of the escalator truss to distribute the load can be reduced, thus effectively improving the overall efficiency of the escalator renovation.

[0055] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0056] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0057] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] This application provides an integrated modification structure for escalator intermediate support and connection. This structure connects the first truss 31 and the second truss 32 of the escalator truss 30 and supports the connection area between the first truss 31 and the second truss 32. This ensures that the load on the escalator truss 30 is distributed, reducing the probability of local stress concentration and improving the overall safety and reliability of the escalator truss 30. Furthermore, this integrated modification structure can be installed at different locations on the escalator truss 30 as needed, ensuring that the support components 20 provide effective support to the escalator truss 30. Moreover, this integrated modification structure simplifies the construction process and effectively improves work efficiency.

[0059] In some embodiments, such as Figure 1 As shown, the integrated retrofit structure for the escalator's intermediate support and connection includes a connection component 10 and a support component 20. The connection component 10 connects the first truss 31 and the second truss 32 of the escalator truss 30. The support component 20 is disposed on the installation surface 40 and is used to connect with the first truss 31 and the second truss 32. The support component 20 has a support surface, through which it connects and supports the first truss 31 and the second truss 32. The orthographic projection of the connection component 10 on the first plane overlaps with the orthographic projection of the support surface on the first plane, and the first plane is parallel to the support surface.

[0060] Specifically, the support surface is used to achieve surface contact with the bottom surface of the escalator truss 30. The support surface is formed as a flat, machined surface, so that the support member 23 can directly fit against the bottom surface of the escalator truss 30, with a contact area greater than or equal to 2000 mm². Thus, the support surface can disperse the compressive and shear stresses that might otherwise be concentrated in the joint area of ​​the escalator truss 30, that is, it can transform concentrated loads into surface loads. This design can reduce the local peak stress in the joint area of ​​the escalator truss 30 by more than 40%, thereby significantly improving the structural safety, fatigue resistance, and service life of the joint area of ​​the escalator truss 30.

[0061] Specifically, the support component 20 provides a pre-defined surface support for the escalator truss 30. The support surface of the support component 20 is connected to the lower chord 321 of the escalator truss 30, enabling it to directly support the first truss 31 and the second truss 32. This effectively disperses the concentrated stress of the escalator truss 30, reduces the risk of stress concentration in local areas of the escalator truss 30, reduces the probability of stress concentration at the joint area of ​​the first truss 31 and the second truss 32, and improves the safety and reliability of the escalator truss 30.

[0062] In summary, in the integrated modification structure of escalator intermediate support and connection provided in this application embodiment, the connection component 10 is used to connect the first truss 31 and the second truss 32 of the escalator truss 30, the support surface of the support component 20 is used to support and connect the first truss 31 and the second truss 32, the orthographic projection of the connection component 10 on the first plane overlaps with the orthographic projection of the support surface on the first plane, and the first plane is parallel to the support surface.

[0063] This allows the support component 20 to form a surface contact with the escalator truss 30. When the load of the escalator truss 30 is transferred to the support component 20, the load can be distributed to the entire support surface through the large contact area, thereby reducing the risk of local stress concentration in the escalator truss 30. At the same time, since the orthographic projection of the connecting component 10 on the first plane overlaps with the orthographic projection of the support surface on the first plane, the support surface of the support component 20 can provide effective support for the connecting component 10, reducing the risk of stress concentration in the connecting area of ​​the first truss 31 and the second truss 32, improving the connection reliability between the connecting component 10 and the first truss 31 and the second truss 32, and thus improving the safety and reliability of the escalator truss 30.

[0064] Understandably, the installation surface 40 is typically a concrete foundation or steel base on the ground or building structure, which provides a load-bearing foundation for the support components 20 installed thereon.

[0065] In some embodiments, such as Figure 2As shown, the support assembly 20 includes a support base, a bracket 21, a connector 22, and a support member 23. The support base is disposed on the mounting surface 40. The bracket 21 may be triangular, and the triangular bracket 21 has a first connecting portion 211 and a second connecting portion 212 that are interconnected. The first connecting portion 211 is detachably connected to the support base. The support member 23 is disposed on and detachably connected to the second connecting portion 212. The side of the support member 23 facing away from the bracket 21 is constructed as a support surface.

[0066] Specifically, the support member 23 extends along the length of the second connecting portion 212 and is used for detachable connection with the lower chord 321 of the escalator truss 30. The first connecting portion 211 and the second connecting portion 212 can be two sides of a triangular structure, with the length of the second connecting portion 212 being greater than the length of the first connecting portion 211. Furthermore, the lateral height H of the triangular bracket 21 must be less than or equal to the installation space dimension of the exterior decorative panel to avoid affecting the installation of the exterior decorative panel and the site layout. The support member 23 can be constructed as a plate-like structure.

[0067] Therefore, when the escalator truss 30 is subjected to an external load, the load is transferred from the escalator truss 30 to the support member 23, and then through the support member 23 to the second connection portion 212 of the bracket 21. From the second connection portion 212, the load is transferred to the first connection portion 211, and then from the first connection portion 211 to the connector 22. Finally, the load is transferred through the connector 22 to the surface to be installed 40 (e.g., the ground or building structure). In other words, the support component 20, as the force transmission component of the escalator truss 30, smoothly transmits and distributes the load of the escalator truss 30, thus ensuring the overall stability and reliability of the escalator truss 30.

[0068] More specifically, the connector 22 includes a fourth connecting portion 221 and a fifth connecting portion 222 that are connected to each other and form an angle. The fourth connecting portion 221 is connected to the support base, and the fifth connecting portion 222 is connected to the first connecting portion 211.

[0069] In some embodiments, both the support member 23 and the second connecting portion 212 are used along the length direction of the escalator truss 30 (i.e. Figure 1 (The direction of travel of the escalator) extends. At the same time, the support member 23 can cover the connection area between the first truss 31 and the second truss 32 of the escalator truss 30.

[0070] Therefore, the support member 23 and the bracket 21 can strengthen the first truss 31, the second truss 32, and their joint area of ​​the escalator truss 30, providing effective support for the joint area of ​​the first truss 31 and the second truss 32. Furthermore, the support member 23 covers the joint area of ​​the first truss 31 and the second truss 32, avoiding stress concentration or deformation inconsistencies that may occur when the support point is located directly at the joint, ensuring that the load is more evenly and continuously distributed to the support assembly 20 located below the escalator truss 30 when passing through the joint area.

[0071] In some embodiments, such as Figure 3 As shown, to accommodate potential dimensional errors or positional deviations during on-site installation and to achieve rapid and accurate alignment, an adjustment hole 231 is provided on the support member 23. The adjustment hole 231 is configured to extend along the length of the support member 23, and is formed as an elongated or oblong hole.

[0072] During installation, the adjustment hole 231 is used for fasteners to pass through and connect to the lower chord 321 of the escalator truss 30, thereby achieving a fixed connection between the support member 23 and the escalator truss 30.

[0073] Furthermore, since the adjustment hole 231 has a certain adjustment margin (e.g., ±10mm to ±30mm) along its length, during installation, operators can fine-tune the relative position between the support assembly 20 and the connecting assembly 10 within a certain range without needing to cut or make complex adjustments to the support assembly 20 or the escalator truss 30. Therefore, this design greatly improves the tolerance and adaptability of on-site installation, enabling the support assembly 20 to flexibly handle various on-site conditions and achieve rapid assembly when installed with the escalator truss 30.

[0074] In some embodiments, such as Figure 2 As shown, the support includes a support base 24, a support frame 25, and an adjusting member 26. The support base 24 is typically fixed to the surface 40 to be installed. The support frame 25 is mounted on the support base 24 via a fixing member 27, and its top end is connected to a connector 22. The adjusting member 26 is connected to both the connector 22 and the support frame 25. The adjusting member 26 is used to adjust the distance between the connector 22 and the support frame 25, i.e., to adjust the vertical height of the connector 22 relative to the surface 40 to be installed, so that the bracket 21 and the support member 23 mounted on the bracket 21 can contact the bottom surface (i.e., the lower chord 321) of the escalator truss 30.

[0075] In this embodiment, the adjusting member 26 can be other height adjusting mechanisms known in the art, such as a support set bolt, a spiral jack, or a wedge block. The fixing member 27 can be a chemical bolt.

[0076] Therefore, this adjustment method completely eliminates the cumbersome process of adding or removing shims in traditional methods. It is intuitive and quick to operate, and when used with measuring tools such as laser levels, it can easily achieve adjustment accuracy of ±0.5mm or even higher. This ensures that the support component 20 adapts to changes in the height of the escalator truss 30 and maintains the overall straightness and operational stability of the escalator truss 30. At the same time, the precise adjustment mechanism avoids operational vibration problems caused by loose shims.

[0077] In one embodiment, such as Figure 4 As shown, the bracket 21 also includes a third connecting part 213 and a reinforcing part 214. The third connecting part 213 is connected to the first reinforcing part 214 and the second connecting part 212. The third connecting part 213, the first connecting part 211 and the second connecting part 212 enclose a triangular frame. The reinforcing part 214 is disposed inside the triangular frame, thereby improving the structural strength and stability of the bracket 21.

[0078] In some embodiments, such as Figure 1 and Figure 2 As shown, the orthographic projection of the support member 23 in the first plane covers the orthographic projection of the second connecting portion 212 in the first plane. Specifically, the length of the support member 23 is greater than or equal to the length of the second connecting portion 212.

[0079] This results in a larger contact area between the support member 23 and the escalator, which can effectively disperse local stress, avoid local stress concentration in the escalator truss 30, and optimize the force flow distribution.

[0080] In some embodiments, such as Figure 5 and Figure 8 As shown, the connecting assembly 10 includes a first connecting member 11, a second connecting member 12, a plurality of first fasteners 13 and a plurality of second fasteners 15.

[0081] The first connector 11 is used to overlap the upper chord 311 of the first truss 31 and the upper chord 311 of the second truss 32. A plurality of first fasteners 13 are used to connect the first connector 11 to the upper chord 311 of the first truss 31 and the upper chord 311 of the second truss 32. The orthographic projection of the first connector 11 on the first plane overlaps with the orthographic projection of the support surface on the first plane.

[0082] The second connector 12 is inclinedly disposed between the first truss 31 and the second truss 32. Specifically, one end of the second connector 12 is connected to the upper chord 311 of the first truss 31, and the other end of the second connector 12 is connected to the lower chord 321 of the second truss 32, thereby achieving alignment and initial connection between the first truss 31 and the second truss 32.

[0083] like Figure 9As shown, the second fastener 15 is used to fasten the support member 23 to the lower chord 321 of the first truss 31 and the lower chord 321 of the second truss 32, thereby realizing the connection and fixation between the support assembly 20 and the lower chord 321 of the first truss 31 and the second truss 32.

[0084] In some embodiments, such as Figure 5 and Figure 9 As shown, the connecting assembly 10 also includes a reinforcing member 14, which is located at the connection between the first truss 31 and the second truss 32 and extends along the length of the first truss 31 and the second truss 32. Further, multiple reinforcing members 14 are provided, located between the upper chord 311 and the lower chord 321 of the escalator truss 30. Some of the reinforcing members 14 are connected to the upper chord 311 of the first truss 31 and the second truss 32, while others are connected to the lower chord 321 of the first truss 31 and the second truss 32. Simultaneously, the second connecting member 12 is also fastened to the reinforcing member 14 by bolts. Thus, the structural strength between the first truss 31, the second truss 32, and the second connecting member 12 is further enhanced by the addition of the reinforcing member 14.

[0085] It should be noted that, as Figure 8 As shown, the support member 23 is mounted on the bracket 21, and the side of the support member 23 is flush with the side of the lower chord 321 and the side of the reinforcing member 14. Simultaneously, an installation space is formed between the support member 23, the side of the lower chord 321, and the triangular bracket 21. The second fastener 15 passes through both the lower chord 321 and the support member 23 to fix the lower chord 321 and the support member 23 together. This arrangement avoids interference between the second fastener 15 and the bracket 21 after fixing the lower chord 321 and the support member 23.

[0086] When the escalator is operating normally, the load generated by the escalator truss 30 is transferred to the joint area between the first truss 31 and the second truss 32. Since the first fastener 13 fixes the first connector 11 to the joint area of ​​the upper chord 311, the load acting on the upper chord 311 can be effectively distributed through the first connector 11. At the same time, the setting of the second connector 12 and the reinforcing member 14 improves the structural strength of the upper chord 311 and the lower chord 321 themselves and the structure after their connection, and can further distribute the load of the escalator truss 30. By fixing the support member 23 of the support assembly 20 to the joint area of ​​the lower chord 321 through the second fastener 15, the load can then be applied to the support assembly 20 through the support member 23. Therefore, the support assembly 20 bears most of the load at the joint area of ​​the escalator truss 30, thereby significantly reducing the load that the joint assembly 10 needs to bear and transmit. Therefore, by cooperating with the connecting component 10 and the supporting component 20, the large number of connecting plates and bolts that are set on the side of the escalator truss 30 to distribute the load in the traditional solution can be reduced, so as to effectively improve the installation efficiency of the connecting component 10.

[0087] Understandably, in traditional independent connection schemes, at least 52 bolts are required at the connection area. However, with the cooperation of the support component 20 and the connection component 10, the connection strength requirement of the connection component 10 is reduced because the support component 20 bears the main load. Therefore, in this application, it is not necessary to install fasteners on the side of the escalator truss 30. Instead, it is only necessary to connect the first connection component 11 to the upper chord 311 of the first truss 31 and the second truss 32, and connect the support component 23 to the lower chord 321 of the first truss 31 and the second truss 32. Multiple fasteners are arranged on the upper chord 311 and the lower chord 321 respectively to meet the fixing requirements. At this time, the number of fasteners required is greatly reduced. Specifically, the number of bolts is reduced by about 85%, and the overall material cost is reduced by about 35%. Furthermore, it simplifies and speeds up the installation of the connecting component 10 and the escalator truss 30. Workers only need to easily tighten a few fasteners in the open overhead space, and the time for a single connecting operation can be reduced from more than 8 hours to less than 1.5 hours, increasing work efficiency by more than 80%. The adjustment time for the intermediate support component 20 is reduced from more than or equal to 2 hours to less than or equal to 30 minutes, resulting in an overall reduction in working time of at least 75%.

[0088] The embodiments of this application provide an escalator, which includes an escalator truss 30 and an integrated modification structure for intermediate support and connection of the escalator as described in any of the above embodiments.

[0089] Specifically, the escalator truss 30 includes a first truss 31 and a second truss 32, and the connecting component 10 connects the first truss 31 and the second truss 32; the support component 20 is provided on the installation surface 40, and the support component 20 is provided with a support surface, which supports and connects the first truss 31 and the second truss 32. The orthographic projection of the connecting component 10 on the first plane overlaps with the orthographic projection of the support surface on the first plane; the first plane is parallel to the support surface.

[0090] Therefore, the cooperation between the support component 20 and the connecting component 10 improves the safety and reliability of the escalator, significantly shortening the total construction period required for escalator retrofitting, reducing the total time for retrofitting a single escalator from over 12 hours to approximately 2 hours. Secondly, the material costs required for the retrofit are significantly reduced, specifically, the amount of bolts and other components required in the connecting area is reduced by more than 80%. Furthermore, the surface contact design between the support component 20 and the escalator truss 30, and the height adjustment feature of the support component 20 to accommodate the height of the escalator truss 30, ensure the long-term safe operation of the escalator truss 30.

[0091] In an alternative embodiment, such as Figure 6 As shown, the support component 20 is located downstream of the joint between the first truss 31 and the second truss 32 (relative to the upward direction of the escalator), and the support component 20 is connected to the tail end of the first truss 31 and the head end of the second truss 32 through its support member 23. That is, its support surface spans and covers the joint area to ensure a stable support effect for the escalator truss 30.

[0092] In an alternative embodiment, such as Figure 7 As shown, the support component 20 can also be located upstream of the joint between the first truss 31 and the second truss 32 (relative to the downward direction of the escalator); and the support component 20 is connected to the tail end of the first truss 31 and the head end of the second truss 32 through its support member 23, that is, its support surface spans and covers the joint area to ensure that it can provide stable support for the escalator truss 30.

[0093] Furthermore, the support component 20 adopts a modular structural design (including bracket 21, connector 22, and support component 23, etc.). This modular structural design facilitates factory production to ensure quality, and can be quickly hoisted or pre-assembled on site or in the factory, thereby greatly improving the overall efficiency of the renovation project.

[0094] This application provides an integrated modification method for escalator intermediate support and connection, applicable to the integrated modification structure and escalator intermediate support and connection described in any of the above embodiments. The integrated modification method for escalator intermediate support and connection includes:

[0095] Obtain data on the escalators to be modified;

[0096] Select the appropriate support component 20 and connecting component 10 based on the obtained data of the escalator to be modified.

[0097] Remove the original central support and connecting structure of the escalator to be renovated, and clean up the demolition area;

[0098] The support structure and connecting components 10 are placed at the designated positions on the escalator to be modified and assembled with the escalator.

[0099] Adjust the support components 20 and the connecting components 10 to the support nodes between them and the escalator, and ensure that the height and level of the modified escalator are within the set range to form the modified escalator.

[0100] Specifically, during the actual renovation and construction of the escalator, the first step was to select a prefabricated escalator intermediate support and connecting integrated renovation structure of appropriate specifications based on the on-site measurement results. Then, the installation space was cleared, the middle support structure of the original escalator truss 30 was removed, and the connecting area of ​​the escalator truss 30 was cleared to ensure that the installation space of the transition structure was greater than or equal to 300mm.

[0101] Next, the integrated modification structure of the escalator's intermediate support and connector is moved to the designated position, and its top height is initially adjusted using the adjusting component 26. Then, the first truss 31 and the second truss 32 are hoisted to the designated positions. Using the lateral allowance provided by the adjusting hole 231, the position of each support component 20 is finely adjusted so that the support component 23 is aligned with the bottom surface of the lower chord 321 of the escalator truss 30.

[0102] Subsequently, the connecting assembly 10 is installed, and the support member 23, connecting assembly 10, first truss 31, and second truss 32 are initially secured with the first fastener 13 and the second fastener 15. Finally, a precision level is used to measure the overall straightness and elevation of the escalator truss 30. By finely tightening the adjusting pieces 26 at each position, the support points between the support assembly 20 and the escalator truss 30 are precisely leveled. Then, all the first fasteners 13 and second fasteners 15 are finally tightened to the designed torque to complete the overall modification of the escalator.

[0103] As a result, interference between different processes is minimized, assembly difficulty is reduced, labor intensity for workers is lowered, and efficiency is effectively improved.

[0104] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0105] It should be noted that if a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component. If a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0106] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
