[0002] During the installation and use of escalators, it is usually necessary to install an enclosure structure around them to achieve the purposes of aesthetics, safety protection, and preventing foreign objects from entering.

[0003] Traditional escalator enclosures typically use monolithic panels or large sheets of wood for covering, which are then directly fixed to the escalator's main steel structure via welding or bolts. This type of structure often presents challenges in actual installation, including difficulties in adjustment, high alignment precision requirements, and cumbersome disassembly and assembly. Especially when maintenance or replacement of partial panels is needed, a significant portion of the enclosure often requires removal, resulting in low construction efficiency and potential disruption to normal escalator operation. Furthermore, the vibrations generated during escalator operation can cause friction or loosening between the enclosure and the main structure due to rigid connections, affecting structural stability and overall aesthetics.

[0025] Please refer to Figures 1-6 One embodiment of this utility model provides an escalator encapsulation structure to solve the problems of difficulty in adjusting escalator encapsulation structures, high requirements for alignment accuracy, and cumbersome disassembly and assembly in the prior art.

[0026] Specifically, please refer to Figure 1This is a perspective view of an escalator enclosure structure provided in an embodiment of the present invention. The escalator enclosure structure includes an enclosure plate 10, a frame 20, and connectors 30. The enclosure plate 10 serves as the outer protective structure of the escalator, covering the steel structure areas on the sides and bottom of the escalator, providing both safety protection and aesthetic decoration. The enclosure plate 10 adopts a segmented design, consisting of multiple interconnected enclosure plate units 11. In this embodiment, the number of enclosure plate units 11 can be set to 5-8 depending on the length of the escalator. Adjacent enclosure plate units 11 are connected to each other through end flanges 12. Each enclosure plate unit 11 has inwardly extending flanges 12 at both ends. Here, "inward" refers to the direction towards the interior of the escalator. The plane of the flange 12 is perpendicular to the direction of escalator operation, which enhances the structural strength of the enclosure plate unit 11 itself and provides a stress point for the connection with the frame 20.

[0027] Furthermore, the keel 20, serving as the supporting framework for the enclosure plate 10, is fixedly connected to the escalator body. This connection can be achieved through welding or high-strength bolts, ensuring that the keel 20 does not shift when bearing the weight of the enclosure plate 10 and external impact forces. The keel 20 employs a skeletal structure and is arranged along the escalator surface. In this embodiment, the escalator body is a steel truss structure.

[0028] Connectors 30 are spaced apart on the surface of the keel 20. In this embodiment, the connector 30 is an L-shaped corner bracket. One side of the corner bracket is fixed to the keel 20 by bolts 303, and the other side is used to connect to the folded edge 12 of the encapsulation plate unit 11.

[0029] By setting the keel 20 as an intermediate connecting structure, the enclosure plate 10 does not need to be directly connected to the escalator body, which makes it easy to flexibly adjust the installation position according to the specific size of the escalator. At the same time, the high strength of the keel 20 provides stable support for the enclosure plate 10, ensuring the stability of the overall structure.

[0030] In the actual assembly process, the flanges 12 at both ends of the encapsulation plate unit 11 are fixedly connected to the keel 20 through the connectors 30. Specifically, bolts 303 can be used to pass through the screw holes of the flanges 12 and the connectors 30 for fixation. With this connection method, each encapsulation plate unit 11 can be installed and disassembled independently, and adjacent encapsulation plate units 11 form a continuous protective surface through the overlap of the flanges 12.

[0031] In the above technical solution, on the one hand, the encapsulation plate 10 adopts the form of multiple unit combination, which greatly reduces the size and weight of individual components compared with the traditional integral encapsulation plate 10, making it easier to transport and install in narrow spaces; on the other hand, through the cooperation structure of the folded edge 12 and the connector 30, the connection between the encapsulation plate 10 and the keel 20 is more firm and reliable, avoiding the loosening and displacement problems that are easy to occur in the traditional connection method. At the same time, the design of the folded edge 12 enhances the deformation resistance of the encapsulation plate 10 itself, and improves the stability and service life of the entire encapsulation structure.

[0032] As a further improvement of this utility model, the keel 20 includes a main keel 21 and a secondary keel 22. Through the coordinated cooperation of the main and secondary keels 22, a multi-point fixed support system is formed, which further enhances the load-bearing capacity and connection stability of the encapsulation plate 10.

[0033] Please see Figure 2 The main keel 21 serves as the primary load-bearing structure, including a support rod 211, a first connecting rod 212, and a second connecting rod 213. The support rod 211 is horizontally positioned with its extension direction perpendicular to the escalator's running direction, and its cross-section is rectangular to enhance bending resistance. The first connecting rod 212 and the second connecting rod 213 are respectively welded vertically to the left and right ends of the support rod 211, and both extend perpendicularly to the escalator's running direction, forming a "U"-shaped base frame. Connecting members 30 are spaced apart on the outer walls of the first connecting rod 212 and the second connecting rod 213 for connection to the folded edge 12. In some embodiments, the connecting member 30 is an L-shaped angle bracket with a waist-shaped hole, the waist-shaped hole design facilitating fine-tuning of its position during installation.

[0034] The secondary keel 22 serves as an auxiliary support structure and is fixedly connected to the main keel 21. It includes a third connecting rod 231, a fourth connecting rod 222, and a fifth connecting rod 223. The third connecting rod 231 and the fourth connecting rod 222 are mounted on the support rod 211, with their connection points to the support rod 211 approximately at the same distance from the bisection point of the support rod 211. The third connecting rod 231 and the fourth connecting rod 222 extend in approximately the same direction and have approximately the same length. The fifth connecting rod 233 is located at the ends of both, forming a small U-shaped support structure. The fifth connecting rod 233 is approximately parallel to the support rod 211, and the fifth connecting rod 233, the third connecting rod 231, the fourth connecting rod 222, the support rod 211, the first connecting rod 222, and the second connecting rod 223 are approximately positioned on the same plane. The third connecting rod 231 and the fourth connecting rod 222 are vertically welded to the left and right ends of the fifth connecting rod 223, respectively, and both extend along the height direction of the escalator, forming a stable small U-shaped support structure. The outer side wall of the fifth connecting rod 223 is also provided with connecting parts 30 for connecting to the folded edge 12 at intervals, and the specifications of the connecting parts 30 are consistent with those of the first connecting rod 212 and the second connecting rod 213 to ensure the universality of connection with the folded edge 12 of the sealing plate 10.

[0035] During assembly, the support rods 211, first connecting rods 212, and second connecting rods 213 of the main keel 21 are fixed to the escalator body by welding or expansion bolts 303, while the fifth connecting rod 223 of the secondary keel 22 corresponds to the central area of ​​the enclosing plate unit 11. By dividing the main load into the main keel 21 and the secondary keel 22, which assists in sharing part of the load, the entire keel 20 system can provide multi-point connection support for the enclosing plate 10 and also offset external impact forces through its own frame structure, significantly improving the overall rigidity of the enclosing structure.

[0036] As a further improvement of this utility model, the folded edge 12 includes a first folded edge 121 and a second folded edge 122. Through the corresponding connection of the two types of folded edges 12 with the main keel 21 and the secondary keel 22, a multi-point collaborative fixing structure is formed, which further improves the connection strength and positional stability between the encapsulation plate unit 11 and the keel 20.

[0037] The first folded edge 121 extends from the middle region of the enclosing plate unit 11 toward the inner side of the escalator. Its extension length is slightly longer than the folded edge 12 at the edge of the enclosing plate unit 11, and its end remains straight to increase the contact area with the connector 30. The first folded edge 121 is correspondingly set with the fifth connecting rod 223 of the secondary keel 22. Specifically, it is fixed by the connector 30 on the fifth connecting rod 223. One side of the connector 30 is fastened to the fifth connecting rod 223 by bolts 303, and the other side is attached to the first folded edge 121. The bolts 303 passing through both are used to lock them together, so that the middle region of the enclosing plate unit 11 and the secondary keel 22 form a rigid connection.

[0038] The second folded edges 122 are respectively located at the left and right ends of the enclosing plate unit 11, extending from the edge of the enclosing plate unit 11 towards the inside of the escalator, with the extension direction consistent with the first folded edge 121. The second folded edge 122 near the first connecting rod 212 extends towards the first connecting rod 212 of the main keel 21 until it abuts against the outer wall of the first connecting rod 212; the second folded edge 122 near the second connecting rod 213 extends towards the second connecting rod 213 of the main keel 21 until it abuts against the outer wall of the second connecting rod 213. This abutment design allows for pre-positioning during installation, reducing the shaking of the enclosing plate unit 11. Subsequently, the second folded edges 122 are fixed by the connectors 30 on the first connecting rod 212 or the second connecting rod 213, with the connection method consistent with the first folded edge 121, that is, locked to the connectors 30 by bolts 303.

[0039] In the above structure, the first folded edge 121 is connected to the fifth connecting rod 223 of the secondary keel 22, bearing the load in the middle of the enclosing plate unit 11; the second folded edges 122 at the upper and lower ends are connected to the first connecting rod 212 and the second connecting rod 213 of the main keel 21, respectively, fixing the edge position of the enclosing plate unit 11, forming a three-point fixing structure. This design not only makes the stress on the enclosing plate unit 11 more uniform, avoiding deformation due to local stress concentration, but also improves the installation positioning accuracy through the abutment cooperation between the folded edge 12 and the connecting rod, reducing the adjustment time during assembly. At the same time, the multi-point connection method greatly enhances the overall connection rigidity between the enclosing plate unit 11 and the keel 20, effectively preventing the enclosing plate unit 11 from loosening or shifting even under long-term vibration or external impact, further ensuring the stability of the escalator enclosing structure.

[0040] As a further improvement to this utility model, please refer to Figure 2 The encapsulation plate unit 11 includes a first encapsulation plate unit 111 and a second encapsulation plate unit 112, which are arranged side by side in the width direction to jointly form the main protective surface of the encapsulation plate unit 11, and a gap 113 is reserved between the first encapsulation plate unit 111 and the second encapsulation plate unit 112.

[0041] Specifically, the length of the first sealing plate unit 111 and the second sealing plate unit 112 is consistent with the design length of the sealing plate unit 11, and the width is set according to the area protection requirements of the escalator side. In the assembled state, the two ends of the first sealing plate unit 111 in the length direction are connected to the folded edge 12 of the adjacent sealing plate unit 11; one end of the first sealing plate unit 111 in the width direction is parallel to one end of the second sealing plate unit 112 in the width direction, and the gap 113 formed between them runs through the length direction of the sealing plate unit 11, which does not affect the overall protective performance of the sealing plate unit 11, and provides the necessary buffer space for the structure.

[0042] The setting of this gap 113 has multiple technical benefits: During the installation phase, the gap 113 can serve as a margin for fine-tuning the position, making it easier for workers to adjust the relative positions of the first sealing plate unit 111 and the second sealing plate unit 112 according to the actual position of the keel connector 30, reducing assembly accuracy requirements and improving installation efficiency. In addition, when the first sealing plate unit 111 or the second sealing plate unit 112 is partially damaged, one of them can be replaced individually without disassembling the entire sealing plate unit 11, greatly simplifying subsequent maintenance operations.

[0043] It should be noted that the first sealing plate unit 111 and the second sealing plate unit 112 are still provided with a first folded edge 121 and a second folded edge 122 at both ends, respectively. The cooperation method between the folded edge 12 structure and the connecting piece 30 provided on the keel 20 is the same as described above, so as to ensure that although there is a gap 113, the two can still form a stable connection with the keel 20 and jointly maintain the overall structural strength of the sealing plate unit 11.

[0044] As a further improvement of this utility model, a fixing rod 114 is provided in the gap 113. The fixing rod 114 is welded to the fifth connecting rod 223. The fixing rod 114 provides targeted support to the gap 113 area between the first encapsulation plate unit 111 and the second encapsulation plate unit 112, thereby further improving the overall structural rigidity of the encapsulation plate unit 11.

[0045] Specifically, the fixing rod 114 is made of the same material as the keel 20. Its length is the same as the overall length of the wrapping plate 10. Its cross-section is rectangular to enhance its bending resistance. Its width is slightly smaller than the width of the gap 113 to ensure that it can be precisely embedded in the gap 113 between the first wrapping plate unit 111 and the second wrapping plate unit 112, and does not directly contact the wrapping plates 10 on both sides.

[0046] The technical advantage of this structure is that the presence of the fixing rod 114 indirectly limits the relative positions of the first sealing plate unit 111 and the second sealing plate unit 112, preventing abnormal changes in the width of the gap 113 due to shaking during long-term use, thus ensuring the consistency of the appearance of the sealing plate unit 11. At the same time, the connection method between the fixing rod 114 and the fifth connecting rod 223 does not affect the independent connection between the first sealing plate unit 111 and the second sealing plate unit 112 and the keel 20, and still retains the detachability of the individual sealing plate 10, facilitating later maintenance and replacement.

[0047] As a further improvement of this utility model, the fixing rod 114 is provided with a seam patching plate 1141 on the outside. The seam patching plate 1141 covers and protects the gap 113 between the first sealing plate unit 111 and the second sealing plate unit 112. While retaining the buffering function of the gap 113, it optimizes the appearance integrity and dustproof performance of the sealing structure.

[0048] Specifically, the width of the joint patch 1141 is slightly larger than the width of the gap 113, and the length is the same as the length of the fixing rod 114. The cross-section is slightly arc-shaped or flat. When the slightly arc-shaped design is adopted, its convex surface faces the outside of the escalator, which can enhance its own resistance to deformation. When the flat design is adopted, it is flush with the surface of the cover plate 10 to ensure the overall flatness.

[0049] The installation position of the joint patch 1141 must ensure that its two edges are in contact with the surfaces of the first sealing plate unit 111 and the second sealing plate unit 112, respectively, and that it is not rigidly fixed to the two sealing plates 10. That is, the joint patch 1141 is only connected to the fixing rod 114, and a relatively movable gap 113 is maintained between it and the first sealing plate unit 111 and the second sealing plate unit 112. In actual assembly, the joint patch 1141 and the fixing rod 114 can be connected by welding or bolting. This design can completely cover the original gap 113 between the first sealing plate unit 111 and the second sealing plate unit 112 through the joint patch 1141, preventing dust and debris from entering the escalator. It can also prevent squeezing deformation when the sealing plate 10 undergoes slight displacement through the sliding fit between the joint patch 1141 and the sealing plate 10, while not affecting the supporting role of the fixing rod 114 in the gap 113 area.

[0050] As a further improvement to this utility model, please refer to Figures 4-5 A sealing element 13 is provided between two adjacent encapsulation plate units 11. The gap is sealed by precise cooperation with the encapsulation plate unit 11, which not only ensures the integrity of the structure, but also improves the deformation resistance of the connection part.

[0051] Specifically, the seal 13 is made of the same material as the encapsulating plate 10 and is formed into a long strip by stamping, with a shape identical to the two end edges of the encapsulating plate 10 along its length. One side of the seal 13 is used to abut the folded edge 12 surface of one of the encapsulating plate units 11; the other side abuts the folded edge 12 surface of the adjacent encapsulating plate unit 11. The surface of the seal 13 maintains the same smoothness as the encapsulating plate unit 11, ensuring overall visual consistency.

[0052] During installation, one side of the seal 13 is fixed to the flange 12 of one of the encapsulation plate units 11 by spot welding or countersunk bolts. When spot welding is used, the weld depth does not exceed 1 / 3 of the plate thickness to avoid damaging the structural strength of the encapsulation plate unit 11. When countersunk bolts are used, the bolt head is fully embedded in the pre-set countersunk hole of the seal 13, flush with the surface. When two adjacent encapsulation plate units 11 are mated, the other side of the seal 13 abuts against the surface of the flange 12 of the other unit. Preferably, the seal 13 is welded to the flange 12 of one of the two encapsulation plate units 11.

[0053] The technical advantages of this rigid seal 13 are as follows: the precise contact design of the seal 13 can maintain the uniformity of the mating gap over a long period of time, avoiding the problem of gap widening caused by the aging of flexible materials, and extending the service life of the sealing structure. At the same time, the way the seal 13 is fixed to the individual encapsulation plate unit 11 still retains the flexibility of independent disassembly and assembly of adjacent units, facilitating later maintenance and replacement.

[0054] As a further improvement of this utility model, the connector 30 includes a first connecting edge 301 and a second connecting edge 302, which are vertically connected to form a rigid component with an "L" shaped cross section. The connector is connected by bolts 303 on both sides to achieve precise fixation to the keel 20 and the folded edge 12, which not only ensures the connection strength but also provides adjustable margin for installation and improves the structural adaptability.

[0055] Specifically, the connector 30 is made of the same material as the keel 20 to avoid electrochemical corrosion, and dimensional accuracy is ensured by die casting. The width and thickness of the first connecting edge 301 and the second connecting edge 302 meet the load-bearing requirements while reducing the overall weight. The first connecting edge 301 is used to connect with the keel 20, and its surface is provided with waist-shaped through holes at intervals along the length direction. The waist-shaped hole design allows for fine adjustment of the position along the length direction of the keel 20 to compensate for installation errors. The second connecting edge 302 is used to connect with the folded edge 12 of the encapsulation plate 10, and a circular through hole is provided at the corresponding position to precisely match the pre-set screw hole of the folded edge 12.

[0056] Bolt 303 is made of stainless steel and is used with anti-loosening nuts: When connecting the keel 20, bolt 303 passes through the waist-shaped hole of the first connecting edge 301 and is threaded to the pre-installed threaded sleeve on the surface of the keel 20. The threaded sleeve is pre-welded inside the keel 20 to ensure thread strength; When connecting the folded edge 12, bolt 303 passes through the circular through hole of the second connecting edge 302 and is connected to the threaded hole of the folded edge 12. After tightening, the second connecting edge 302 and the folded edge 12 fit tightly together. A thin layer of anti-loosening adhesive can be applied to the mating surface to enhance stability.

[0057] During the assembly process, the connector 30 is first pre-fixed to the keel 20 through the first connecting edge 301. Then, the folded edge 12 of the enclosing plate 10 is aligned with the second connecting edge 302, the bolt 303 is inserted and initially tightened. At this time, the relative position of the connector 30 and the keel 20 can be adjusted with the help of the waist-shaped hole of the first connecting edge 301 so that the folded edge 12 and the keel 20 are parallel or at a preset angle. After confirming that the position is correct, the bolts 303 on both sides are fully tightened.

[0058] The technical advantages of this structure are as follows: First, the "L"-shaped double connecting edge design enables the keel 20 and the folded edge 12 to form a perpendicular force relationship, dispersing the load transmitted by the encapsulation plate 10 and avoiding deformation caused by excessive force at a single point; Second, the combination design of the waist-shaped hole and the round hole not only solves the problem of positional deviation when the keel 20 and the folded edge 12 are installed, but also ensures the precise positioning of the folded edge 12 connection; Third, the bolt 303 connection method is easier to disassemble and maintain later than welding. When the encapsulation plate 10 or the keel 20 needs to be replaced, the parts can be separated simply by loosening the bolt 303 without damaging the overall structure.

[0059] As a further improvement of this utility model, the keel 20 is made of aluminum and the encapsulation plate 10 is made of stainless steel. By complementing the characteristics of the two materials, an optimized balance between lightweight and corrosion resistance is achieved while ensuring structural strength and durability.

[0060] Specifically, the keel 20 is made of aluminum, a material with excellent comprehensive mechanical properties after heat treatment, which can meet the support and load-bearing requirements of the enclosing plate 10. Compared with the traditional steel keel 20, it is lighter and significantly reduces the additional load on the escalator body, and also facilitates the handling and positioning of the keel 20 during installation. From a processing perspective, aluminum has excellent ductility and machinability. The support rods 211, connecting rods, and surface connectors 30 of the keel 20 can be manufactured with high precision through extrusion molding and CNC machining, ensuring that the dimensional tolerances of each component are controlled within a suitable range, and improving the assembly compatibility with the enclosing plate 10.

[0061] The cladding panel 10 is made of stainless steel, which has excellent corrosion resistance and mechanical strength, resisting bumps, friction, and moisture erosion during daily use. Even if the surface is stained, it can be easily cleaned with a wipe, maintaining its aesthetic appearance. At the same time, its high yield strength ensures that the folded edge 12 is not easily deformed under long-term stress, maintaining the stability of the connection with the keel 20. Furthermore, the stainless steel surface can be hammered to match the overall decorative style of the escalator, enhancing the visual harmony of the public space.

[0062] Please see Figure 6 In the actual assembly process, the middle section of the escalator enclosure structure is usually a regular inclined straight section, and the enclosure plate 10, keel 20 and other components are arranged in a continuous and uniform manner; however, the two ends, that is, the parts connecting the upper floor slab, the lower area or the machine room, need to be connected with the building structure to realize the transition of the steps.

[0063] During assembly, the middle section of the escalator enclosure structure is first installed in place according to the design dimensions. Then, the actual structural dimensions of the upper and lower ends of the escalator are obtained through on-site measurements, such as the outline shape of the enclosure plate 10 and the keel 20 and the gap dimensions with the building interface. The end edges of the enclosure plate 10 and the keel 20 are cut and trimmed so that the cut enclosure end outline is precisely matched with the actual structure of the escalator end and the shape of the building connection.

[0064] With this treatment, the escalator enclosure structure can not only completely wrap the middle running section of the escalator, but also smoothly connect with the end components of the escalator and the building structure at both ends, ensuring the installation is firm and the appearance is flat.

[0065] Based on the foregoing embodiments, this utility model also provides an escalator, which includes an escalator enclosure structure as described in any of the above embodiments.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but 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 utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
