Description

Technical Field

[0001] This application relates to the field of escalator testing technology, and in particular, to a comb plate mechanism that is easy to manually adjust. Furthermore, this application also relates to a teaching escalator including the aforementioned manually adjustable comb plate mechanism. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] Escalators are fixed, electrically driven devices with circulating steps used to transport passengers upwards or downwards at an incline. They are widely used in public places such as subways, train stations, shopping malls, and hotels. With the continuous improvement of people's living standards, rapid economic development, and ongoing improvements in production and daily life, escalators have become fully integrated into our lives and work. To further enhance escalator safety and the skills of maintenance personnel, while also improving the customer experience, elevator maintenance personnel must be trained and certified before starting work. According to the regulations of relevant departments in my country, elevator operation is classified as special operation, and operators must undergo professional training and pass both theoretical and practical examinations before being issued a "Special Operation Certificate" to be allowed to operate the elevator.

[0004] Elevator maintenance personnel play a crucial role in ensuring the smooth and safe operation of escalators. Therefore, providing them with adequate training to improve their technical skills and troubleshooting abilities is of paramount importance. For example, Chinese patent publication CN216817669U discloses an escalator fault simulation teaching aid that requires no disassembly, has a clear and intuitive structure, making training more intuitive for trainees. It simulates a wide range of fault types, and the fault simulation can be directly activated via a specially designed fault button within the fault box, preventing escalator damage caused by improper operation.

[0005] For existing escalators used in teaching, please refer to the instruction manual attached. Figure 5The escalator 100 for teaching purposes includes a comb plate 1 and a connecting base plate 2. The comb plate 1 is located at the entrance / exit of the running steps or treads, facilitating passenger transition and engaging with the steps or treads. It also serves as a safety protection device for the escalator. A microswitch is located behind the comb plate 1. If a foreign object becomes lodged in the comb plate 1, the distance between the comb plate 1 and the connecting base plate 2 will decrease, thus stopping the escalator via the microswitch. For example, Chinese Patent Publication No. CN 220787767 U discloses a safety protection structure for an escalator comb plate. Through the cooperation of a buffer mechanism, connecting rod, slider, and spring, the escalator comb plate has a certain buffering function. This allows it to buffer when the escalator comb plate comes into contact with a foreign object, protecting the escalator comb plate from damage. Furthermore, the protective components can promptly send a signal to brake the escalator when a shoelace becomes lodged in the comb plate, ensuring high safety.

[0006] However, the existing teaching escalator 100 is a scaled-down version of the actual escalator structure, which is difficult to manually control and conveniently demonstrates the malfunction of the comb plate 1 getting stuck with foreign objects, affecting the convenience and quality of teaching.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

The adjusting member passes through the adjusting screw hole and is connected to the adjusting screw hole by a thread. The tail end of the adjusting member is used to abut against the second locking member. The adjusting member is used to be driven to rotate and drive the adjusting plate to move along the length direction of the second limiting hole through the threaded engagement, thereby causing the comb plate to move closer to or away from the connecting base plate.

[0012] In some embodiments of this application, the displacement adjustment assembly further includes a first locking member for locking the adjustment plate to the comb plate.

[0013] In some embodiments of this application, the first locking member passes through the second limiting hole and connects to the first connecting screw hole preset on the comb plate.

[0025] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0026] Figure 1 This is a schematic diagram of the overall structure of a preferred embodiment of this application; Figure 2 This is a schematic diagram of the displacement adjustment component according to a preferred embodiment of this application; Figure 3 This is a schematic diagram of the installation of the comb plate according to a preferred embodiment of this application; Figure 4 This is a schematic diagram of the structure of the connecting base plate according to a preferred embodiment of this application; Figure 5 This is a schematic diagram of an existing escalator used in teaching.

[0027] A comb plate mechanism that is easy to manually adjust includes a comb plate 1, a connecting base plate 2, and a displacement adjustment component 3. The connecting base plate 2 is used to be installed on a teaching escalator 100. The comb plate 1 is slidably connected to the connecting base plate 2. The displacement adjustment component 3 connects the comb plate 1 and the connecting base plate 2 into a whole and is used to adjust the distance between the comb plate 1 and the connecting base plate 2. The displacement adjustment component 3 includes an adjustment plate 31 and an adjustment element 34. The first end of the adjustment plate 31 is fixedly connected to the comb plate 1, and the second end of the adjustment plate 31 is slidably connected to the connecting base plate 2. The adjustment element 34 is connected to the adjustment plate 31 and is used to drive the adjustment plate 31 to move and, through the adjustment plate 31, to move the comb plate 1 closer to or away from the connecting base plate 2. The adjustment element 34 is also used to lock and fix the adjustment plate 31 to the connecting base plate 2.

[0028] The comb plate mechanism of this application, which is easy to manually adjust, is connected to the connecting base plate 2 by a sliding connection between the comb plate 1 and the connecting base plate 2. One side of the adjusting plate 31 is fixedly connected to the comb plate 1, and the other side of the adjusting plate 31 is slidably connected to the connecting base plate 2. The adjusting component 34 drives the comb plate 1 and the adjusting plate 31 to slide, so as to make the comb plate 1 move closer to or away from the connecting base plate 2, thus simulating and demonstrating the failure of the comb plate 1 being stuck with foreign objects.

[0029] Preferably, please refer to Figure 1 and Figure 2 As shown, the top surface of the adjusting plate 31 is provided with a second limiting hole 311 extending along the line connecting the comb plate 1 and the connecting base plate 2. The displacement adjusting assembly 3 also includes a second locking member 33. The second locking member 33 passes through the second limiting hole 311 and is connected to a second connecting screw hole pre-set on the connecting base plate 2. At least one end of the adjusting plate 31 along the length direction of the second limiting hole 311 is provided with an adjusting screw hole 312 communicating with the second limiting hole 311. The adjusting member 34 passes through the adjusting screw hole 312 and is connected to the adjusting screw hole 312 by a thread. The tail end of the adjusting member 34 is used to abut against the second locking member 33. The adjusting member 34 is used to be driven to rotate and drive the adjusting plate 31 to move along the length direction of the second limiting hole 311 through the threaded engagement, thereby making the comb plate 1 move closer to or away from the connecting base plate 2.

[0030] It is understood that the adjusting plate 31 is fixedly connected to the comb plate 1, while the adjusting plate 31 is slidably connected to the connecting base plate 2. The second locking member 33 is vertically mounted on the connecting base plate 2, and the second limiting hole 311 is slidably engaged with the second locking member 33. The second locking member 33 can limit the sliding of the adjusting plate 31 through the second limiting hole 311. The adjusting member 34 is threadedly connected to the adjusting plate 31, and the tail end of the adjusting member 34 abuts against the second locking member 33. When the operator turns the adjusting member 34, it can drive the adjusting plate 31 to move along the axial direction of the adjusting member 34, thereby moving the comb plate 1 closer to or away from the connecting base plate 2, realizing a simulation demonstration of the fault where the comb plate 1 is stuck with a foreign object. The overall adjustment operation is very simple, and the fault display effect is very intuitive and easy to understand, which is conducive to improving the convenience and teaching effect of teaching.

[0031] Preferably, please refer to Figure 1 As shown, the displacement adjustment assembly 3 also includes a first locking member 32, which is used to connect and lock the adjustment plate 31 to the comb plate 1.

[0032] Specifically, the first locking member 32 passes through the second limiting hole 311 and is connected to the first connecting screw hole preset on the comb plate 1. The first locking member 32 is used to abut against the side wall of the second limiting hole 311 away from the second locking member 33.

[0033] In this preferred embodiment, please refer to Figure 2 , 3 As shown in Figure 4, the connecting base plate 2 has a first limiting hole 22 extending along the line connecting the comb plate 1 and the connecting base plate 2 at the position corresponding to the first connecting screw hole. The first locking member 32 passes through the first connecting screw hole and is embedded in the first limiting hole 22 and is used to guide and slide along the first limiting hole 22.

[0034] Understandably, the locking mechanism 32, in conjunction with the second limiting hole 311, achieves locking and limiting between the adjusting plate 31 and the comb plate 1, facilitating quick assembly and disassembly of the adjusting plate 31 and the comb plate 1 by removing the first locking mechanism 32. Simultaneously, the first locking mechanism 32 can cooperate with the first limiting hole 22 to guide the movement of the adjusting plate 31 and the comb plate 1, ensuring the smooth movement of the comb plate 1.

[0035] Optionally, both the first locking member 32 and the second locking member 33 are made of long bolts. By using standard parts, the procurement and manufacturing costs can be reduced, and the maintenance of teaching equipment can be facilitated.

[0036] Preferably, the displacement adjustment assembly 3 further includes a compression spring that presses between the first locking member 32 and the second locking member 33, and the compression spring is used to provide an elastic force to push the first locking member 32 away from the second locking member 33.

[0037] It is understandable that by setting a compression spring between the first locking member 32 and the second locking member 33, not only can the compression spring push the first locking member 32 to abut against and tighten the adjusting plate 31, thus improving the connection stability between the comb plate 1 and the adjusting plate 31, but also when the adjusting member 34 causes the adjusting plate 31 to move, the compression spring can provide a buffering effect between the adjusting plate 31 and the comb plate 1 and the connecting base plate 2, avoiding rigid collision damage to the comb plate 1 and the connecting base plate 2, which is beneficial to ensuring the safety of each component.

[0038] Preferably, please refer to Figure 2 As shown, the adjusting member 34 includes an adjusting screw, the tail end of which is used to abut against the second locking member 33, and the head of the adjusting screw is provided with a handle.

[0039] Understandably, by providing a handle at the head of the adjusting screw, the operator can easily rotate the adjusting component 34 by turning the handle, which improves the convenience of operation and reduces the labor intensity of rotating the adjusting component 34. By turning the adjusting component 34 in conjunction with the compression spring set between the first locking component 32 and the second locking component 33, the distance between the comb plate 1 and the connecting base plate 2 can be adjusted (that is, the sliding stroke of the comb plate 1 is controlled).

[0040] Preferably, please refer to Figure 2 As shown, the bottom of the comb plate 1 is provided with a first inclined surface 12, and the first end of the connecting base plate 2 facing the comb plate 1 is provided with a second inclined surface 23. The second inclined surface 23 is used to abut against the first inclined surface 1 when the comb plate 1 slides close to the connecting base plate 2 to lift the comb plate 1.

[0041] Understandably, since a compression spring is provided between the first locking member 32 and the second locking member 33, in order to allow the adjusting plate 31 to slide flexibly, the second locking member 33 does not completely lock the adjusting plate 31 to the connecting base plate 2, so that the adjusting plate 31 has a certain amount of room for movement in the vertical direction, which can realize the simulation of the comb plate 1 being impacted. The second inclined surface 23 can abut against the first inclined surface 12, so that the comb plate 1 slides and then slightly lifts, which is convenient for the sensors preset in the escalator to detect the displacement of the comb plate 1, and realize a more realistic simulation of the comb plate 1 getting stuck.

[0042] Preferably, please refer to Figure 1 As shown, the bottom of the comb plate 1 is provided with a first locking groove 11, and the top of the connecting base plate 2 is provided with a second locking groove 21. The first locking groove 11 and the second locking groove 21 are used to abut against each other so that the top surface of the comb plate 1 is flush with the top surface of the connecting base plate 2.

[0043] It is understandable that the comb plate 1 and the connecting base plate 2 can be interlocked through the first locking groove 11 and the second locking groove 21, thereby making the top surfaces of the comb plate 1 and the connecting base plate 2 flush. It should be noted that the structural arrangement of the first locking groove 11 and the second locking groove 21 allows a gap to be formed between the side wall of the first locking groove 11 and the side wall of the connecting base plate 2. This gap facilitates the distance sensor to measure the displacement change of the comb plate 1, thereby diagnosing whether there is a foreign object stuck in the comb plate 1 and triggering the emergency stop switch in time.

[0044] According to another aspect of this application, a teaching escalator is also provided, which includes the aforementioned comb plate mechanism that is easy to manually adjust. Furthermore, the overall structure of this application is more streamlined than the actual escalator comb plate installation structure, has lower manufacturing costs, and allows for convenient manual adjustment of the comb plate 1's displacement, making it highly suitable for teaching demonstrations and improving teaching effectiveness and quality.

[0045] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] This document uses specific examples to illustrate the principles and implementation methods of this application. The examples are merely for the purpose of helping to understand the method and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of written expression, and the existence of an infinite number of specific structures, those skilled in the art can make various improvements, modifications, or variations without departing from the principles of this application, and can also combine the above technical features in an appropriate manner. These improvements, modifications, variations, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered as protected by this application.
