Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to an escalator anti-fall device. Background Technology

[0002] With escalators widely used in various public places, such as shopping malls, subway stations, and airports, safety issues related to escalators are becoming increasingly prominent. In recent years, with the increase in the proportion of the elderly population and the frequency of public travel, safety accidents on escalators have been on the rise, especially those caused by passengers losing their balance and falling, accidentally falling while holding children or carrying items, or falling due to playing, roughhousing, or leaning on the handrails. These incidents seriously threaten passenger safety. Traditional escalator designs often do not adequately consider fall protection or are only equipped with basic guardrails, which are inadequate in dealing with emergencies and cannot effectively prevent falls. To improve public transportation safety and reduce falls on escalators, the installation of efficient and reliable fall protection devices has become an urgent need.

[0003] However, in practice, installing fall arrestors faces numerous technical challenges. On one hand, traditional installation methods often require on-site welding or drilling of the escalator truss, which not only increases construction difficulty and cost but may also adversely affect the overall structural strength of the escalator, even posing safety hazards. On the other hand, different models and materials of escalators have varying shapes and sizes of cover plates, columns, and truss vertical members. Designing a fall arrestor that is versatile, easy to install, and does not affect the original decorative structure has become an urgent problem to be solved. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an escalator anti-fall device, which has the advantage of fixing the anti-fall column by clamping and fixing components, and can achieve the installation of the anti-fall device without damaging the escalator structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An escalator fall prevention device includes: a fall prevention column, one end of which is provided with a glass claw and the other end with a connecting plate; and a clamping and fixing assembly, which is connected to the fall prevention column through the connecting plate and is used to clamp an external structure to fix the fall prevention column.

[0007] Compared to existing technologies, this application, by setting up a fall arrestor column and clamping fixing components, can effectively fix the fall arrestor onto the escalator. The glass claw at one end of the fall arrestor column can be fitted with protective components such as glass baffles to provide physical protection for passengers and prevent falls. The clamping fixing components are connected to the fall arrestor column via connecting plates and clamp external structures such as escalator cover plate columns or truss vertical bars. This allows for the stable installation of the fall arrestor on the escalator without altering its original structure, ensuring the device's basic fall arrest function.

[0008] As a preferred embodiment of the present invention, the clamping and fixing assembly includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are detachably connected, a clamping area is formed between the first clamping plate and the second clamping plate, and the first clamping plate is connected to the connecting plate.

[0009] The above-mentioned solution employs a design where the first and second clamping plates are detachably connected to form a clamping area to hold the external structure. This structure makes installation and disassembly more flexible and convenient, enabling the clamping and fixing of the fall arrestor without altering the escalator structure. Secondly, when maintenance, replacement, or adjustment of the fall arrestor is required, the clamping plates can be quickly disassembled and reinstalled. Simultaneously, the connection between the first clamping plate and the connecting plate ensures a stable connection between the fall arrestor and the clamping and fixing assembly, improving the reliability and stability of the entire fall arrestor.

[0010] As a preferred embodiment of the present invention, the first clamping plate includes a clamping part and a connecting part, the clamping part is connected to the connecting part, the clamping part is detachably connected to the second clamping plate, and the connecting part is connected to the connecting plate.

[0011] Using the above solution, the clamping part is responsible for cooperating with the second clamping plate to clamp the external structure, and the connecting part is used to connect with the connecting plate. During installation, the clamping part can be connected with the second clamping plate to clamp the external structure, thereby achieving the clamping and fixing of the anti-fall column without modifying the escalator structure. At the same time, this fixing method also effectively improves the installation efficiency of the anti-fall column.

[0012] As a preferred embodiment of the present invention, the first clamping plate further includes reinforcing ribs, which are connected to the clamping portion and the connecting portion respectively.

[0013] By adopting the above-mentioned solution, reinforcing ribs are provided on the first clamping plate and connected to the clamping part and the connecting part respectively. This can effectively enhance the overall structural strength of the first clamping plate. When the fall protection device is subjected to external force, the reinforcing ribs can effectively disperse the stress and prevent the first clamping plate from deforming or breaking, thereby ensuring the stability of the clamping and fixing components and improving the safety and service life of the fall protection device.

[0014] As a preferred embodiment of this utility model, the clamping part is connected to the second clamping plate by bolts.

[0015] The above-mentioned solution uses bolts to connect the clamping part to the second clamping plate. This connection method has high reliability and stability. The bolt connection can provide a large connection force to ensure that the clamping plate will not loosen or fall off when clamping the external structure. At the same time, the bolt connection is easy to disassemble and install. When it is necessary to adjust the clamping position or replace the clamping plate, the operation is simple and convenient, which improves the maintainability of the device.

[0016] As a preferred embodiment of this utility model, both the first clamping plate and the second clamping plate are provided with positioning holes.

[0017] By adopting the above solution, positioning holes are provided on the first clamping plate and the second clamping plate, which can be positioned after the first clamping plate and the second clamping plate are installed. With the help of positioning pins, the first clamping plate and the second clamping plate can be fixed in the installation position to prevent slippage, thereby improving the installation quality and stability of the entire fall arrest device.

[0018] As a preferred embodiment of this utility model, one end of the connecting plate is connected to the first clamping plate by bolts, and the other end is connected to the anti-fall column by bolts.

[0019] Using the above-described scheme, both ends of the connecting plate are bolted together, connecting to the first clamping plate and the fall arrestor column respectively. This connection method is simple and reliable, ensuring the strength and stability of the connection points. Bolted connections facilitate installation and disassembly. When maintenance or replacement of parts is required for the fall arrestor device, the connection between the connecting plate and the clamping plate / column can be quickly separated, improving maintenance efficiency. Simultaneously, the bolted connection can withstand certain tensile and shear forces, ensuring the fall arrestor column is securely installed on the escalator via the connecting plate and clamping fixing components.

[0020] The aforementioned escalator fall arrest device has the following advantages: Firstly, the first and second clamping plates can fix the fall arrest column to the external structure such as the escalator truss or cover plate column through clamping and fixing, thus allowing the fall arrest column to be fixed without altering the escalator structure, avoiding changes in the escalator's structural strength due to modifications. Secondly, the clamping and fixing method improves the installation efficiency of the fall arrest column, and since the clamping and fixing part is part of the escalator structure itself, it reduces the requirements for the foundation for installing the fall arrest device on the escalator.

[0028] This utility model proposes an escalator anti-fall device.

[0029] Reference Figure 1 In one embodiment of this utility model, an escalator fall prevention device includes: a fall prevention column 1 and a clamping and fixing assembly 4. One end of the fall prevention column 1 is welded with a glass claw 2, and the other end is bolted to a connecting plate 3. The clamping and fixing assembly 4 is connected to the fall prevention column 1 via the connecting plate 3 and is used to clamp external structures to fix the fall prevention column 1. This application, by setting the fall prevention column 1 and the clamping and fixing assembly 4, can effectively fix the fall prevention device on the escalator. The glass claw 2 at one end of the fall prevention column 1 can be fitted with protective components such as glass baffles to provide physical barriers for passengers and prevent falls. The clamping and fixing assembly 4 is connected to the fall prevention column 1 via the connecting plate 3 and clamps external structures such as escalator cover column 5 or truss vertical rods. This allows for the stable installation of the fall prevention device on the escalator without modifying the original escalator structure, ensuring the basic fall prevention function of the device.

[0030] Reference Figure 1 and Figure 2In one embodiment, the clamping and fixing assembly 4 includes a first clamping plate 41 and a second clamping plate 42. In this embodiment, both the first clamping plate 41 and the second clamping plate 42 are made of bent parts, and their shapes can be flexibly designed according to the shape of the vertical rod of the escalator truss or the cover plate column 5. The first clamping plate 41 and the second clamping plate 42 are detachably connected, and a clamping area is formed between the first clamping plate 41 and the second clamping plate 42. The first clamping plate 41 is connected to the connecting plate 3. The first clamping plate 41 includes a clamping part 411 and a connecting part 412. The clamping part 411 and the connecting part 412 are integrally formed. The clamping part 411 is connected to the second clamping plate 42 by bolts. One end of the connecting plate 3 is connected to the clamping part 411 by bolts, and the other end is connected to the anti-fall column 1 by bolts. The first clamping plate 41 also includes a reinforcing rib 43, which is welded to the clamping part 411 and the connecting part 412 respectively. The clamping and fixing assembly 4 adopts a design with a detachable connection between the first clamping plate 41 and the second clamping plate 42, forming a clamping area to clamp the external structure. This structure makes installation and disassembly more flexible and convenient, allowing the anti-fall column 1 to be clamped and fixed without modifying the escalator structure. Secondly, when maintenance, replacement, or adjustment of the anti-fall device is required, the clamping plates can be quickly disassembled and reinstalled. At the same time, the first clamping plate 41 is connected to the connecting plate 3, ensuring a stable connection between the anti-fall column 1 and the clamping and fixing assembly 4, improving the reliability and stability of the entire anti-fall device. The clamping part 411 is responsible for cooperating with the second clamping plate 42 to clamp the external structure, and the connecting part 412 is used to connect to the connecting plate 3. During installation, the clamping part 411 can be connected to the second clamping plate 42 to clamp the external structure, thereby achieving the clamping and fixing of the anti-fall column 1 without modifying the escalator structure. At the same time, this fixing method also effectively improves the installation efficiency of the anti-fall column 1. A reinforcing rib 43 is provided on the first clamping plate 41 and connected to the clamping part 411 and the connecting part 412 respectively. This effectively enhances the overall structural strength of the first clamping plate 41. When the fall arrestor is subjected to external force, the reinforcing rib 43 can effectively disperse the stress and prevent the first clamping plate 41 from deforming or breaking, thereby ensuring the stability of the clamping and fixing assembly 4 and improving the safety and service life of the fall arrestor. The clamping part 411 is connected to the second clamping plate 42 by bolts. This connection method has high reliability and stability. The bolt connection can provide a large connection force to ensure that the clamping plate will not loosen or fall off when clamping the external structure. At the same time, the bolt connection is easy to disassemble and install. When it is necessary to adjust the clamping position or replace the clamping plate, the operation is simple and convenient, improving the maintainability of the device. Both ends of the connecting plate 3 are bolted to the first clamping plate 41 and the fall arrestor column 1 respectively. This connection method is simple and reliable and can ensure the strength and stability of the connecting part 412.Bolted connections facilitate installation and disassembly. When it is necessary to repair or replace parts of the fall arrest device, the connection between the connecting plate 3 and the clamping plate and column can be quickly separated, improving maintenance efficiency. At the same time, bolted connections can withstand a certain amount of tension and shear force, ensuring that the fall arrest column 1 is securely installed on the escalator through the connecting plate 3 and the clamping and fixing components 4.

[0031] Reference Figure 2 In one embodiment, to improve the stability of the first clamping plate 41 and the second clamping plate 42 clamping onto the cover plate column 5 or the vertical member of the escalator truss, a pad 6 is provided between the cover plate column 5 and the first clamping plate 41 or between the vertical member of the escalator truss and the first clamping plate 41. The pad 6 is welded onto the clamping portion 411 of the first clamping plate 41. The pad 6 effectively eliminates the problem of unstable clamping caused by the mismatch between the arc transition portion between the clamping portion 411 and the connecting portion 412 and the right-angle portion on the cover plate column 5 or the vertical member of the escalator truss.

[0032] Reference Figure 2 In one embodiment, both the first clamping plate 41 and the second clamping plate 42 are provided with positioning holes 44. The positioning holes 44 are provided on the first clamping plate 41 and the second clamping plate 42, and the positions of the two positioning holes 44 correspond to each other. The positioning holes 44 allow for drilling at the corresponding positions on the vertical rods or cover plate columns 5 of the escalator truss after the first clamping plate 41 and the second clamping plate 42 are installed. With the help of positioning pins, the first clamping plate 41 and the second clamping plate 42 can be fixed in their installation positions to prevent slippage, thereby improving the installation quality and stability of the entire fall arrest device.

[0033] The first clamping plate 41 and the second clamping plate 42 can fix the fall arrestor column 1 to the external structure such as the escalator truss or cover plate column 5 by clamping and fixing. This allows the fall arrestor column 1 to be fixed without modifying the escalator structure, avoiding the problem of changes in the strength of the escalator structure due to modifications. Secondly, the clamping and fixing method can improve the installation efficiency of the fall arrestor column 1. At the same time, since the clamping and fixing part is the escalator structure itself, the requirements for the fixed foundation for adding fall arrestor devices to the escalator are reduced.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
