Description

Technical Field

[0001] This utility model relates to the field of escalator technology, specifically to an escalator step. Background Technology

[0002] Escalators, as a safe and efficient means of transportation, are widely used in public places such as shopping malls, airports, high-speed rail stations, and subway stations. Escalator steps are the stair interfaces on escalators, providing a place for passengers to stand. They are also the main moving parts when the escalator is running, and their performance has a significant impact on the overall quality of the escalator and the safety of passengers when standing. The design and manufacture of escalator steps must meet strict safety standards to ensure the safety of passengers when riding escalators.

[0003] However, in the current technology, the escalators used in some older residential or commercial buildings are inconsistent with current escalator standards, such as step size, shape, and connection method. This makes it difficult for new steps to be directly adapted, forcing the maintenance and replacement of steps in older escalators to choose between complete replacement or customized parts. Customized parts require the factory to create additional molds for the kick pedals, which is more expensive than complete replacement, making the replacement of older escalators difficult overall. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an escalator step to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is an escalator step, including a fixed frame assembly, a tread, and a kick plate, wherein:

[0006] The pedal extends along a first direction and is located at the top of the fixed frame assembly, while the kick plate is located on one side of the fixed frame assembly along a second direction.

[0007] The pedal has a fixed end near the kick plate along the first direction. The fixed end includes a stop protrusion that extends along the first direction and is located on the top of the pedal. The stop protrusion has a stepped portion on the side facing the kick plate along the second direction and a limiting groove on the side away from the kick plate.

[0008] The top of the kick plate is provided with a mounting portion, which includes a snap-fit ​​groove extending along the first direction and engaging with the stop protrusion. The snap-fit ​​groove has a snap-fit ​​protrusion on the side facing the pedal along the second direction, and a connecting portion on the side away from the pedal. The snap-fit ​​protrusion corresponds to the step portion, and the connecting portion corresponds to the limiting groove.

[0009] The pedal and kick plate provided by this utility model are connected by the interlocking of a stop protrusion and a snap-fit ​​groove. This detachable structure makes the disassembly and installation of the ladder steps more convenient. During routine maintenance or replacement of damaged parts, it is not necessary to replace the entire ladder step; only the damaged part needs to be disassembled and replaced, greatly reducing maintenance costs and time. Furthermore, this split structure allows the pedal and kick plate to be made of appropriate materials and manufacturing processes as needed, significantly reducing the overall manufacturing cost compared to using a mold for the kick plate as a single unit.

[0010] In some embodiments, along a third direction, the depth of the limiting groove is less than the depth of the step portion, and the length of the snap-fit ​​protrusion is less than the length of the connecting portion.

[0011] Using the above technical solution, the depth of the limiting groove is less than the depth of the step, and the length of the snap-fit ​​protrusion is less than the length of the connecting part. This design can better limit the relative position between the pedal and the kick plate, making the connection between the pedal and the kick plate more flexible and easier to disassemble and install.

[0012] In some embodiments, a retention gap is provided between the snap-fit ​​protrusion and the limiting groove along a third direction.

[0013] By adopting the above technical solution, the existence of the gap allows the steps to better adapt to the slight deformation of the track during operation, thereby improving the stability of operation.

[0014] In some embodiments, the pedal includes multiple sub-pedals, which are spliced ​​together along the first direction, and each sub-pedal has the fixed end. The kick plate includes multiple sub-kick plates, which are spliced ​​together along the first direction, and each sub-pedal has the mounting portion.

[0015] Using the above technical solution, the splicing design of the sub-pedal / sub-kick plate is less expensive than the overall mold-making process, while making the subsequent installation process more flexible and efficient. Installers can quickly assemble the sub-pedal / sub-kick plate into a complete pedal / kick plate, reducing on-site installation time.

[0016] In some embodiments, the limiting groove extends through the sub-pedal along the first direction.

[0017] In some embodiments, the two ends of the limiting groove along the first direction and the two ends of the sub-pedal along the first direction are spaced apart.

[0018] In some embodiments, the escalator step further includes a fixed bracket, which is located at the bottom of the step and includes a fixed plate and connecting pieces. The fixed plate extends in a third direction and has connecting pieces at both ends for connecting and fixing to the step and the kick plate respectively via the connecting pieces.

[0019] By adopting the above technical solution, the fixed bracket is connected to the pedal and kick plate through the fixed plate and connecting piece to form an integral structure, which effectively enhances the overall stability of the steps.

[0020] In some embodiments, the fixing frame assembly includes two triangular frames spaced apart along the first direction, each triangular frame having a mounting flange at its connection to the pedal and the kick plate. The bottom of each triangular frame along the second direction away from the kick plate has a main shaft embedding area, and the bottom of the side closer to the kick plate has a drive wheel seat. The drive wheel seat contains a rotating bearing and a driven wheel rotatably connected to the rotating bearing.

[0021] By adopting the above technical solution, the triangular frame structure itself has good stability and load-bearing capacity, which can effectively support the pedal and kick plate and reduce deformation caused by passengers stepping on it or external impact.

[0022] In some embodiments, the escalator step further includes a first fixing plate and a second fixing plate. The first fixing plate is disposed on the side of the kick plate facing the fixing frame assembly along the second direction. The second fixing plate extends along the third direction and is disposed on the side of the fixing frame assembly away from the kick plate along the second direction, with its bottom connected to the tread.

[0023] By adopting the above technical solution, the force on the tread and kick plate can be distributed to the fixing frame assembly through the connection of the first fixing plate and the second fixing plate. This double fixing design can effectively enhance the overall structural stability of the ladder, reduce local stress concentration, and thus improve the load-bearing capacity and service life of the ladder.

[0024] In some embodiments, the top of the pedal is provided with yellow plastic strips at both ends along the first direction and at both ends along the second direction.

[0025] Using the above technical solution, the yellow plastic strip can clearly mark the boundary of the pedal, allowing passengers to see the range of the pedal more clearly and avoid stepping into the air or stepping on the edge of the pedal, thereby improving passenger safety.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0034] refer to Figures 1 to 3 , Figure 1 This invention provides a three-dimensional representation of an escalator step 1 according to an embodiment of the present invention. Figure 1 ; Figure 2 for Figure 1 Structural diagram; Figure 3 This invention provides a three-dimensional representation of an escalator step 1 according to an embodiment of the present invention. Figure 2 Specifically, Figure 1 and Figure 3 Perspective views of escalator step 1 in two different embodiments. Figure 1 The number of sub-pedal 25 and sub-kick plate 34 are both 3, wherein the limiting groove 23 is provided to pass through the sub-pedal 25 along the first direction; Figure 3 The number of sub-pedal 25 and sub-kick plate 34 is two, wherein the two ends of the limiting groove 23 along the first direction and the two ends of the sub-pedal 25 along the first direction are spaced apart.

[0035] like Figures 1 to 3As shown, the technical solution adopted by this utility model is an escalator step 1, including a fixed frame assembly, a step 2, and a kick plate 3, wherein:

[0036] Pedal 2 along the first direction ( Figure 1 Extending in the X direction and positioned at the top of the fixed frame assembly, the kick plate 3 is positioned along the second direction of the fixed frame assembly. Figure 1 (As shown in the Y direction) on one side.

[0037] The pedal 2 has a fixed end 20 at one end near the kick plate 3 along the first direction. The fixed end 20 includes a stop protrusion 21, which extends along the first direction and is located at the top of the pedal 2. The stop protrusion 21 has a stepped portion 22 on the side facing the kick plate 3 along the second direction, and a limiting groove 23 on the side away from the kick plate 3.

[0038] The top of the kick plate 3 is provided with a mounting part 30, which includes a snap-fit ​​groove 31. The snap-fit ​​groove 31 extends along a first direction and is configured to engage with the stop protrusion 21. The snap-fit ​​groove 31 has a snap-fit ​​protrusion 32 on the side facing the pedal 2 along a second direction, and a connecting part 33 on the side away from the pedal 2. The snap-fit ​​protrusion 32 is configured to correspond with the step part 22, and the connecting part 33 is configured to correspond with the limiting groove 23.

[0039] This application provides an escalator step 1, tread 2, and kick plate 3 connected by a stop protrusion 21 and a snap-fit ​​groove 31. This detachable structure makes the disassembly and installation of the step more convenient. During routine maintenance or replacement of damaged parts, it is not necessary to replace the entire step; only the damaged part needs to be disassembled and replaced, greatly reducing maintenance costs and time. Furthermore, this split structure allows tread 2 and kick plate 3 to be made of appropriate materials and manufacturing processes as needed, significantly reducing the overall manufacturing cost compared to using a molded joint for the kick plate 2.

[0040] In some embodiments, reference Figures 1 to 3 Along the third direction ( Figure 1 (As shown in the Z direction), the setting depth of the limiting groove 23 is less than the setting depth of the step portion 22, and the setting length of the snap-fit ​​protrusion 32 is less than the setting length of the connecting portion 33.

[0041] With the above technical solution, the depth of the limiting groove 23 is less than the depth of the step 22, and the length of the snap-fit ​​protrusion 32 is less than the length of the connecting part 33. This design can better limit the relative position between the tread 2 and the kick plate 3, making the connection between the tread 2 and the kick plate 3 more flexible, and making disassembly and installation more convenient. Furthermore, during the operation of the escalator, even if it is subjected to external impact or uneven stepping by passengers, the tread 2 and the kick plate 3 can maintain a stable connection, reducing the risk of loosening or falling off.

[0042] In some embodiments, reference Figures 1 to 3 Along the third direction, a retention gap 24 is provided between the snap-fit ​​protrusion 32 and the limiting groove 23.

[0043] For example, since the kick plate 3 and the pedal 2 are not set perpendicularly, the kick plate 3 will be set tilted towards the pedal 2. By setting the retention gap 24, a certain rotation setting range can be provided for the kick plate 3. In addition, the existence of the retention gap 24 allows the steps to better adapt to the small deformation of the track during operation, thereby improving the smoothness of operation.

[0044] In some embodiments, reference Figures 1 to 3 The pedal 2 includes multiple sub-pedales 25, which are spliced ​​together along a first direction, and each sub-pedal 25 is provided with a fixed end 20. The kick plate 3 includes multiple sub-kick plates 34, which are spliced ​​together along a first direction, and each sub-pedal 25 is provided with a mounting part 30.

[0045] For example, the splicing design of the sub-pedal 25 / sub-kick plate 34 is less costly than the overall molded manufacturing, while making the subsequent installation process more flexible and efficient. Installers can quickly assemble the sub-pedal 25 / sub-kick plate 34 into a complete pedal 2 / kick plate 3, reducing on-site installation time. When a sub-pedal 25 is damaged, only that part needs to be replaced, instead of replacing the entire pedal 2, further reducing maintenance costs.

[0046] In some embodiments, reference Figures 1 to 3 The limiting groove 23 is provided to pass through the sub-pedal 25 along the first direction.

[0047] For example, such as Figure 2 As shown, the design of the limiting groove 23 passing through the sub-pedal 25 makes the snap-fit ​​protrusions 32 of multiple sub-kick plates 34 form a whole after splicing, which enhances the overall structural stability of the pedal 2, can better adapt to the running trajectory of the escalator, and reduce running vibration caused by uneven splicing.

[0048] refer to Figure 4 and Figure 5 , Figure 4 for Figure 3 A structural diagram. Figure 5 for Figure 3 A schematic diagram of the structure of the middle kick plate 3.

[0049] In some embodiments, reference Figures 1 to 5 The limiting groove 23 is spaced apart from the two ends of the sub-pedal 25 along the first direction.

[0050] For example, such as Figure 5As shown, in this example, the limiting groove 23 is not through-hole set, but is spaced apart from the edge of the sub-pedal 25, so that the snap-fit ​​protrusion 32 of the sub-kick plate 34 is inserted into the limiting groove 23, which can effectively limit the relative displacement between the sub-kick plates 34 and reduce loosening caused by vibration or external force.

[0051] In some embodiments, reference Figures 1 to 5 The escalator step 1 also includes a fixed bracket 4, which is located at the bottom of the step 2 and includes a fixed plate 40 and a connecting piece 41. The fixed plate 40 extends along a third direction and has connecting pieces 41 at both ends for bolting and fixing to the step 2 and the kick plate 3 respectively.

[0052] For example, the fixed bracket 4 is connected to the tread 2 and the kick plate 3 via the fixed plate 40 and the connecting piece 41, forming an integral structure that effectively enhances the overall stability of the ladder. Furthermore, the design of the fixed bracket 4 makes the installation of the tread 2 and the kick plate 3 more convenient. Installers can quickly connect the tread 2 and the kick plate 3 with bolts, reducing on-site installation time and workload. When a part of the tread 2 or the kick plate 3 is damaged, only the damaged part needs to be replaced, without replacing the entire ladder, thus reducing maintenance costs.

[0053] In some embodiments, reference Figures 1 to 5 The fixed frame assembly includes two triangular frames 50 spaced apart along a first direction. Each triangular frame 50 has a mounting flange 51 at its connection to the pedal 2 and the kick plate 3. A main shaft embedding area 52 is provided at the bottom of the side of the triangular frame 50 away from the kick plate 3 along a second direction, and a drive wheel seat is provided at the bottom of the side closer to the kick plate 3. A rotating bearing 53 is provided within the drive wheel seat, along with a driven wheel 54 rotatably connected to the rotating bearing 53.

[0054] For example, the triangular frame 50 structure itself has good stability and load-bearing capacity, effectively supporting the pedal 2 and kick plate 3, reducing deformation caused by passenger stepping or external impact. The mounting flange 51 is used for bolt connection and fixation, further enhancing the connection strength between the pedal 2 and kick plate 3 and the triangular frame 50, ensuring structural stability during long-term use. (Reference) Figure 2 and Figure 3 In this embodiment Figure 2 and Figure 3 The main shaft embedding area 52 is arc-shaped. Specifically, the main shaft embedding area 52 can also adopt other shapes to match the escalator to be installed.

[0055] In some embodiments, reference Figure 1 and Figure 2The escalator step 1 also includes a first fixing plate 60 and a second fixing plate 61. The first fixing plate 60 is located on the side of the kick plate 3 facing the fixing frame assembly in the second direction. The second fixing plate 61 extends in the third direction and is located on the side of the fixing frame assembly away from the kick plate 3 in the second direction, with its bottom connected to the step 2.

[0056] For example, by connecting the first fixing plate 60 and the second fixing plate 61, the force on the tread 2 and the kick plate 3 can be distributed to the fixing frame assembly. This double fixing design can effectively enhance the overall structural stability of the ladder and reduce local stress concentration, thereby improving the load-bearing capacity and service life of the ladder.

[0057] In some embodiments, reference Figure 1 The top of the pedal 2 is provided with yellow plastic strips 26 at both ends along the first direction and at both ends along the second direction.

[0058] For example, the yellow plastic strip 26 can clearly mark the boundary of the pedal 2, allowing passengers to see the range of the pedal 2 more clearly and avoid stepping into the air or stepping on the edge of the pedal 2, thereby improving passenger safety.

[0059] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
