Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of aisle indicator light, and particularly relates to a hanging structure and an aisle indicator light based on the hanging structure. BACKGROUND

[0002] In modern factory buildings and industrial environments, the widespread use of aisle indicator lights is closely related to safe operation. Although traditional aisle indicator lights can provide basic lighting and guiding functions, their single and rigid installation methods are very limited in dynamic working environments and are difficult to meet the demand for flexible adjustment. As production plans and process flows continue to change, fixed aisle indicator lights cannot adapt to the movement of personnel and equipment, resulting in a decrease in the effectiveness of the indicator information.

[0003] In complex industrial environments, production lines and work areas are often adjusted, and fixed indicator lights cannot be adjusted according to real-time needs, which not only reduces the practicality of the indicator lights but also may cause safety hazards. Therefore, there is an urgent need for a hanging aisle indicator light that can be adjusted in real time without interfering with other equipment. The position of the indicator light can be flexibly changed. During peak working hours, the indicator light can be lowered in height to ensure that the lighting information is clear and visible. During equipment maintenance and periods of low human flow, the indicator light can be raised to reduce visual interference. SUMMARY

[0005] The present application provides a hanging structure and an aisle indicator light based on the hanging structure, and the specific technical solutions are as follows:

[0006] The hanging mechanism is divided into an unfolded state and a tightened state. In the unfolded state, the servo motor drives the screw rod to rotate forward, the lifting nut moves downward, the limiting wheels on both sides of the support beam rotate clockwise, the lifting rope is loosened, the folding bar is unfolded along the cross groove, and the passage indicator light below it is lowered. In the tightened state, the servo motor drives the screw rod to rotate reversely, the lifting nut moves upward, the limiting wheels on both sides of the support beam rotate counterclockwise, the lifting rope is tightened, the folding bar is close to the return shaft along the cross groove, and the passage indicator light below it moves upward.

[0007] As a preferred technical solution of the present application, the C-shaped plate is staggered and arranged obliquely, and can be stacked in a circumferential direction with the unfolding and tightening of the folding bar.

[0008] As a preferred technical solution of the present application, the outer circumferential surface of the return shaft is provided with a plurality of annular grooves, and a through stable groove corresponding to the cross groove is arranged at the edge of the annular groove. The upper annular groove is a first return groove, the lower annular groove is a second return groove, and two symmetrical intermediate shafts are arranged on the surface of the opening and closing table. The intermediate shaft is provided with an intermediate groove corresponding to the annular groove of the return shaft. One end of the lifting rope is connected to the connecting hole, and is fixed to the circumferential surface of the V-shaped groove through the stable groove, the first return groove and the intermediate groove, for accurately adjusting the lifting of the hanging mechanism.

[0009] As a preferred technical solution of the present application, L-shaped adapter pads are symmetrically arranged on both sides of the lifting nut close to the limiting wheels, and a through hole is arranged at the short end of the L-shaped adapter pad for 90° adapter limiting of the lifting rope.

[0010] As a preferred technical solution of the present application, the folding bar is divided into a horizontal bar and a vertical bar in different directions, the horizontal bar is longer than the vertical bar, the upper end connecting hole of the horizontal bar is arranged in the first return groove, the upper end connecting hole of the vertical bar is arranged in the second return groove, and two lifting ropes are respectively connected to the upper end connecting holes of the horizontal bar and the vertical bar, and are fixed to the circumferential surface of the V-shaped groove through the stable groove, the first return groove and the intermediate groove, for reducing the lifting adjustment stroke of the hanging mechanism.

[0011] As a preferred technical solution of the present application, a cylindrical dust cover is arranged at the lower end of the opening and closing table, for folding dust prevention of the passage indicator light.

[0012] As a preferred technical solution of the present application, an organ cover is arranged on the outer circumferential surface of the screw rod, and can be folded and unfolded with the upward and downward movement of the lifting nut, for dust prevention of the screw rod.

[0013] As a preferred technical solution of the present application, bearings are arranged on the shafts of the first return groove, the second return groove and the intermediate groove, for reducing the resistance of the reciprocating traction of the lifting rope.

[0014] As a preferred technical solution of the present application, the material of the lifting rope is steel wire rope.

[0015] As a preferred technical solution of the present application, the passageway indicating lamp is provided with warning light sources symmetrically arranged on the peripheral surface, and a corresponding induction lamp is arranged on the top.

[0016] The present application has the following advantages:

[0017] The present application overcomes the defects of single suspension and difficulty in adjustment of the fixed passageway indicating lamp in the prior art, and has significant advantages. First, by using the lifting mechanism, the indicating lamp can be adjusted up and down according to actual needs, breaking the limitation of traditional installation and suspension. This scheme uses a servo motor to drive the rotation of the lead screw, which drives the lifting nut and cantilever to move up and down, thereby realizing the height adjustment of the indicating lamp.

In the tightened state, the folding strip is close to the rotating shaft, and the indicating lamp is moved up, saving the space inside the factory building and avoiding the safety hazards that may be caused by the long-term low position of the indicating lamp, such as collision and dust accumulation. Not only does it increase the flexibility of the hanging structure, but also effectively improves the service life of the indicating lamp and the maintenance convenience.

[0019] In addition, the design of the limiting wheel ensures the stability and safety during lifting. The limiting wheel rotates synchronously with the lifting nut, ensuring that the loosening and tightening process of the lifting rope will not be stuck or jammed, so that the lifting movement of the indicating lamp is smoother. Compared with the traditional fixed indicating lamp, this scheme greatly reduces the structural damage and imbalance that may be caused by unstable lifting, and improves the reliability of the overall system.

[0020] It is worth mentioning that the modular design of the hanging structure facilitates the maintenance and replacement of the system in the later stage. Since the components of the hanging mechanism are connected independently to work together, users can maintain and replace the components individually according to actual needs, without the need to disassemble the entire system, reducing maintenance cost and time. At the same time, the hollow hat-shaped opening and closing table design of the hanging mechanism also helps to reduce the weight of the system, improving the stability and durability of the structure.

[0021] In summary, the design not only solves the limitations of traditional fixed indicator lights in height adjustment and space utilization, but also realizes flexible lifting and space optimization of the indicator light through the ingenious design of the folding strip and the lifting rope, greatly improving the adaptability and use efficiency of the indicator light. The structure is simple and reasonable, easy to operate, and can meet the use requirements in different scenes, and provides protection for industrial safety. BRIEF DESCRIPTION OF DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0033] Embodiment one

[0034] To solve the technical problems in the background art, the following hanging structure and aisle indicator lamp 4 based on the hanging structure are given:

[0035] As shown in the combination Figures 1-7 The hanging structure and aisle indicator lamp 4 based on the hanging structure include a lifting mechanism 2 erected on a rack 1, a servo motor 21 is erected at the bottom of the lifting mechanism 2, a shaft coupling 22 is connected to the power output end of the servo motor 21, a vertical support beam 27 is arranged between the fixed seat 24 and the top of the rack 1, a lead screw 23 is sleeved on the shaft coupling 22, the lead screw 23 is arranged in the fixed seat 24 and is sleeved with a lifting nut 26, the lifting nut 26 can rotate and lift with the lead screw 23, a longitudinally extending cantilever is erected on both sides of the lifting nut 26, a limiting wheel 25 with a V-shaped groove 251 is arranged between the vertical support beams 27 at the back of the cantilever, the limiting wheel 25 can rotate synchronously with the lifting nut 26, a hanging mechanism 3 is arranged at the front end of the cantilever, the hanging mechanism 3 includes a hollow hat-shaped opening and closing table 31 erected between the cantilevers, a cross groove 311 is arranged in the top wall of the opening and closing table 31, a rotating shaft 314 is arranged at the intersection of the cross groove 311, a plurality of folding bars 32 are arranged in the cross groove 311, the both ends of the folding bars 32 are symmetrically arranged with a plurality of connecting holes 3211, the upper end connecting holes 3211 are connected with a lifting rope 34 fixed on the surface of the limiting wheel 25, the lifting rope 34 passes through the rotating shaft 314, and the lifting rope 34 can rotate with the limiting wheel 25 and adjust the expansion and contraction of the folding bars 32, the lower end connecting holes 3211 of the folding bars 32 are connected with corresponding C-shaped plates 33, the bottom of the C-shaped plates 33 is extended with a hook 331, and the aisle indicator lamp 4 is hung on the hook 331.

[0036] The hanging mechanism 3 is divided into an expanded state and a tightened state, in the expanded state, the servo motor 21 drives the lead screw 23 to rotate forward, the lifting nut 26 moves downward, the limiting wheels 25 on both sides of the support beam 27 rotate clockwise, the lifting rope 34 is loosened, the folding bars 32 expand along the cross groove 311, and the aisle indicator lamp 4 under the folding bars 32 moves downward; in the tightened state, the servo motor 21 drives the lead screw 23 to rotate reversely, the lifting nut 26 moves upward, the limiting wheels 25 on both sides of the support beam 27 rotate counterclockwise, the lifting rope 34 is tightened, the folding bars 32 are close to the rotating shaft 314 along the cross groove 311, and the aisle indicator lamp 4 under the folding bars 32 moves upward.

[0037] By the above technical scheme, the device overcomes the defects of single suspension and difficulty in adjustment of the fixed passageway indicating lamp 4 in the prior art, and has remarkable beneficial effects. First, by adopting the lifting mechanism 2, the indicating lamp can be adjusted up and down according to actual needs, breaking the limitation of traditional installation and suspension. The scheme utilizes the servo motor 21 to drive the screw rod 23 to rotate, drives the lifting nut 26 and the cantilever to move up and down, thereby realizing height adjustment of the indicating lamp. In this way, whether in daily use or in maintenance, the position of the indicating lamp can be flexibly adjusted according to different actual needs, providing more personalized lighting guidance.

[0038] Secondly, by unfolding and tightening the folding strip 32, the flexibility and operability of the system are further enhanced. In the unfolded state, the folding strip 32 is unfolded along the cross groove 311, and the indicating lamp is lowered, which is convenient for omnidirectional guidance and illumination of the passageway. In the tightened state, the folding strip 32 is close to the rotating shaft 314, the indicating lamp is moved up, the space inside the factory building is saved, and potential safety hazards such as collision and dust accumulation caused by the long-term low position of the indicating lamp are avoided. Not only the flexibility of the hanging structure is increased, but also the service life of the indicating lamp and the maintenance convenience are effectively improved.

[0039] In addition, the design of the limiting wheel 25 ensures the stability and safety during lifting. The limiting wheel 25 rotates synchronously with the lifting nut 26, ensuring that the loosening and tightening process of the lifting rope 34 will not be stuck and jammed, so that the lifting movement of the indicating lamp is smoother. Compared with the traditional fixed indicating lamp, this scheme greatly reduces the structural damage imbalance caused by unstable lifting, and improves the reliability of the whole system.

[0040] It is worth mentioning that the modular design of the hanging structure facilitates the maintenance and replacement of the system in the later stage. Since the components of the hanging mechanism 3 are cooperatively worked through independent mechanical connection, the user can individually maintain and replace the components according to actual needs, without the need to disassemble the whole system, thereby reducing the maintenance cost and time. At the same time, the hollow hat-shaped opening and closing table 31 of the hanging mechanism 3 also helps to reduce the weight of the system, and improves the stability and durability of the structure.

[0041] In summary, the design not only solves the limitations of traditional fixed indicating lamp in height adjustment and space utilization, but also realizes flexible lifting and space optimization of the indicating lamp through the ingenious design of the folding strip 32 and the lifting rope 34, greatly improving the adaptability and use efficiency of the indicating lamp. The structure is simple and reasonable, easy to operate, and can meet the use needs in different scenes, providing protection for industrial safety.

[0042] Embodiment two

[0043] As Figures 3-6As shown, on the basis of the above embodiments, the present embodiment further gives the following contents:

[0044] In the present embodiment, the C-shaped plates 33 are arranged staggered and obliquely, and can be stacked in a circumferential direction with the unfolding and tightening of the folding strips 32.

[0045] The passageway indicator light 4 is symmetrically arranged with warning light sources 41 on its circumference, and the top is provided with corresponding induction lights 42.

[0046] The lower end of the opening and closing platform 31 is provided with a cylindrical dust cover 312 for folding dust prevention of the passageway indicator light 4, and when the hanging mechanism is completely lifted to the highest position by the lead screw, the passageway indicator light is completely stored in the opening and closing platform through the lifting rope of the hanging mechanism, which ensures that it is not affected by dust, moisture, collision and other adverse effects, and when the hanging mechanism is completely lowered to the lowest position by the lead screw, the passageway indicator light is expanded downward through the lifting rope of the hanging mechanism into the opening and closing platform, which fully illuminates and warns.

[0047] The design is optimized to cope with various challenges in harsh environments, especially in conditions such as dust, moisture, collision, etc., and can maintain long-term stable performance. The passageway indicator light 4 overcomes the shortcomings of traditional indicator lights that are easily affected by the environment through efficient protection design and intelligent lifting system, improves the durability, functionality and safety of the equipment, and is suitable for industrial, warehouse, transportation, commercial and other complex scenes.

[0048] Firstly, the passageway indicator light 4 in the present design has the functions of automatic storage and expansion, and uses the hanging mechanism 3 and the lifting rope 34 system to automatically expand and provide sufficient lighting and warning function when needed. The lifting mechanism is driven by the lead screw 23, which can accurately adjust the height of the indicator light to ensure that the indicator light can be in the appropriate working position when in use. The stored indicator light can also effectively reduce the space occupation, especially suitable for places with limited space.

[0049] In addition, the external protection design of the passageway indicator light 4 further enhances its adaptability. The lower end of the indicator light is equipped with a cylindrical dust cover 312, which can effectively prevent external dust and moisture from entering the interior of the lamp. Whether in places with high dust, high humidity, or exposed to rain and wind, when not in use, the indicator light can be completely stored in the dust cover 312, avoiding long-term exposure to the external environment, thereby preventing dust, moisture, and other external factors from affecting the light source, avoiding the degradation of the light source or electrical failure due to dust accumulation, providing additional protection for the indicator light, and effectively extending the service life of the equipment. The design of the dust cover 312 allows the device to minimize contact with the environment when not in use, keeping the lamp clean and reducing the occurrence of malfunctions, and when the indicator light is in use, it is lowered by folding the folding strip 32 and the C-shaped plate 33, completely separating from the dust cover 312, avoiding the dust cover 312 obstructing the light refraction of the indicator light, thereby achieving efficient storage.

[0050] The light source arrangement of the indicator light itself is also carefully designed to ensure sufficient and uniform illumination under different working conditions. The warning light sources 41 arranged symmetrically around the lamp increase the brightness and visibility range of the light source while providing clear indicator light function, improving the safety of the passageway indicator light 4. In complex or dim environments, this arrangement ensures that the indicator light can be clearly seen regardless of the flow of people, fully guaranteeing the effectiveness of the indicator light. In addition, the setting of the induction light 42 further enhances the intelligence and response ability of the lamp, which can automatically adjust the brightness of the lamp according to the change of the surrounding light, automatically enhance the lighting effect in low light environment, and automatically reduce the brightness when the surrounding light is sufficient, reducing energy consumption.

[0051] During use, the intelligent lifting system of the indicator light can be flexibly adjusted according to actual needs. When the use demand of the workplace changes, the passageway indicator light 4 can be quickly adjusted to the appropriate lighting angle and height to ensure the best indication effect. When maintenance or cleaning is required, the lamp can be easily retracted into the dust cover 312 by the lifting device, and will not be affected by water droplets, dust, or other contaminants in the environment, so maintenance personnel do not need to worry about the damage to the equipment due to long-term exposure.

[0052] The design also fully considers the safety of the equipment. In the design of the hanging mechanism 3, high-strength materials and protective measures are used to ensure the stability and safety of the equipment during hanging and lifting. The hanging mechanism 3 uses a pure mechanical mechanism to smoothly and accurately adjust the position of the indicator light, avoiding mechanical failure and reducing the possibility of component aging and damage due to long-term exposure of the equipment.

[0053] To sum up, the design combines multiple technologies such as dust prevention, intelligent lifting, light source arrangement, etc., which not only significantly improves the reliability of the passageway indicator light 4 in harsh environments, but also enhances its adaptability and safety. Whether in an environment with heavy dust, humidity, or narrow space, the indicator light can provide stable and efficient lighting and warning functions, meeting the high requirements of industrial, commercial, and other places, and improving the convenience of use, significantly reducing the failure rate and long-term use cost, and ensuring long-term efficient operation.

[0054] Embodiment three

[0055] As Figures 1-9 shown, on the basis of the above embodiment, the present embodiment further gives the following contents:

[0056] The outer peripheral surface of the rotating shaft 314 is provided with a plurality of annular grooves, and a through stable groove 3143 corresponding to the cross groove 311 is provided at the edge of the annular groove. The upper annular groove is the first rotating groove 3141, and the lower annular groove is the second rotating groove 3142. In addition, two symmetrical transfer shafts 313 are arranged on the transfer platform 31. The transfer shaft 313 is provided with a transfer groove 3131 corresponding to the annular groove of the rotating shaft 314. One end of the lifting rope 34 is connected to the connection hole 3211, and is fixed to the peripheral surface of the V-shaped groove 251 through the stable groove 3143, the first rotating groove 3141 and the transfer groove 3131, for accurately adjusting the lifting of the hanging mechanism 3.

[0057] The L-shaped transfer pad 28 is symmetrically arranged on both sides of the lifting nut 26 close to the limiting wheel 25, and the short end of the L-shaped transfer pad 28 is provided with a through hole 281 for 90° transfer and limiting of the lifting rope 34.

[0058] The folding strip 32 is divided into a horizontal strip 321 and a vertical strip 322 in different directions, and the horizontal strip 321 is longer than the vertical strip 322. The upper end connection hole 3211 of the horizontal strip 321 is arranged on the first rotating groove 3141, and the upper end connection hole 3211 of the vertical strip 322 is arranged on the second rotating groove 3142. In addition, two lifting ropes 34 are respectively connected to the upper end connection holes 3211 of the horizontal strip 321 and the vertical strip 322, and are fixed to the peripheral surface of the V-shaped groove 251 through the stable groove 3143, the first rotating groove 3141, the second rotating groove 3142 and the transfer groove 3131, for reducing the lifting adjustment stroke of the hanging mechanism 3.

[0059] The shafts of the first rotating groove 3141, the second rotating groove 3142 and the transfer groove 3131 are provided with bearings for reducing the resistance of the reciprocating traction of the lifting rope 34.

[0060] The material of the lifting rope 34 is steel wire rope.

[0061] By the above technical scheme, the problem that the aisle indicator light 4 is difficult to accurately control in the lifting adjustment process is effectively solved, and significant beneficial effects are exhibited. First, the design of the multiple annular grooves and the stabilizing groove 3143 provided on the outer circumferential surface of the rotating shaft 314 ensures the stability and accuracy of the lifting rope 34 when winding around the rotating shaft 314. Traditional lifting structures usually have problems such as rope slipping and unstable path, but by providing the first rotating groove 3141 and the second rotating groove 3142 on the rotating shaft 314, the lifting rope 34 made of steel wire can be pulled along a fixed path, avoiding the phenomenon of unstable lifting of the indicator light caused by deviation of the rope path, not only improving the stability of the lifting process, but also making the adjustment process more smooth and accurate, greatly reducing the error in operation.

[0062] Secondly, the transfer shaft 313 on the opening and closing table 31 and its corresponding transfer groove 3131 provide additional guiding support for the lifting rope 34, further enhancing the precision of the lifting system. The lifting rope 34 can obtain better traction path control during lifting by cooperating with the rotating groove through the transfer groove 3131, avoiding the winding misplacement phenomenon of the rope during lifting. This design is particularly suitable for scenarios that require frequent height adjustment, ensuring that the hanging mechanism 3 can still maintain height consistency and stability during multiple lifting operations.

[0063] In addition, the application of the L-shaped adapter pad 28 provides a 90° adapter limiting function for the lifting rope 34, solving the problem of uneven force and rapid wear at the rope corner in traditional lifting devices. By setting the adapter pad 28 in the path of the lifting rope 34, the lifting rope 34 can be effectively supported and guided at the corner, avoiding the breakage of the rope caused by excessive friction at the corner, not only prolonging the service life of the lifting rope 34, but also making the operation of the entire lifting system more smooth, reducing the maintenance frequency and cost.

[0064] In the design of the folding strip 32, the scheme further optimizes the lifting adjustment loop of the hanging mechanism 3 by dividing the folding strip 32 into horizontal strips 321 and vertical strips 322 and pulling them through different rotating grooves. The different lengths of the horizontal strips 321 and the vertical strips 322 make the unfolding and tightening of each folding strip 32 during lifting more reasonably distribute the lifting space, avoiding interference between the folding strips 32 during lifting. This hierarchical folding strip 32 design not only reduces the lifting stroke of the hanging mechanism 3, but also makes the entire system more compact and efficient during lifting, improving space utilization.

[0065] Finally, the introduction of bearings significantly reduces the resistance during the reciprocating traction process of the lifting rope 34. In traditional lifting devices, prolonged friction of the rope often leads to decreased lifting efficiency and increased resistance. However, this solution, by placing bearings at the axis of the rotary groove and the intermediate groove 3131, effectively reduces the friction between the rope and the groove wall. This not only improves the efficiency of the lifting process but also reduces energy consumption, resulting in a smaller load on the servo motor 21 and extending its service life. Simultaneously, the use of bearings also makes lifting operations easier and allows for more convenient height adjustment of the passageway indicator light 4.

[0066] In summary, this design, through the optimized combination of various structures such as the rotating shaft 314, annular groove, stabilizing groove 3143, central shaft 313, L-shaped transition pad 28, folding strip 32 layered design, and bearings, significantly improves the lifting and adjustment accuracy and ease of operation of the aisle indicator light 4. Its precise path control and reasonable force distribution not only solve the problem of difficult precise adjustment of traditional indicator light lifting, but also improve the system's stability, durability, and efficiency, ensuring precise adjustment of the hanging structure.

[0067] Example 4

[0068] like Figure 7 As shown, based on the above embodiments, this embodiment further provides the following:

[0069] The outer circumferential surface of the lead screw 23 is fitted with a bellows cover 231, which can be folded and unfolded as the lifting nut 26 moves up and down, for dust protection of the lead screw 23.

[0070] The above technical solution effectively solves the problem of dust accumulation on the lead screw 23 due to exposure during lifting and lowering, providing significant protection. The bellows cover 231 is designed to fold and unfold synchronously with the up-and-down movement of the lifting nut 26, ensuring comprehensive protection for the lead screw 23 in any working state and preventing dust and impurities from entering its surface and affecting its normal operation. Compared to the traditional exposed lead screw 23 structure, the bellows cover 231 not only extends the service life of the lead screw 23 but also reduces frictional resistance and mechanical wear caused by dust accumulation, improving system stability and ease of maintenance. Furthermore, the flexible structure of the bellows cover 231 does not affect the lifting and lowering movement of the lead screw 23, combining dust protection with operational flexibility, making it an efficient and practical protective measure.

[0071] Working principle and usage process of this invention:

[0072] First, before use, the operator needs to check and initialize the system, ensuring that all components are working properly, including the lifting mechanism 2, servo motor 21, lifting nut 26 and connected lifting rope 34 can operate normally. After confirming that the equipment is in good condition, the operator can start the lifting function of the indicator light.

[0073] After starting, the servo motor 21 receives instructions to start operation, and the coupling 22 drives the screw rod 23 to rotate. With the rotation of the screw rod 23, the lifting nut 26 moves up and down along the screw rod 23. In this process, the movement of the lifting nut 26 guides the lifting of the cantilever, and the limit wheel 25 rotates synchronously to ensure the stability of the entire system. When the lifting nut 26 moves downward, the connected lifting rope 34 begins to relax, and the folding strip 32 also unfolds according to the instructions, so that the passage indicator light 4 descends to the predetermined height.

[0074] At the same time when the lamp is descending, the clockwise rotation of the limit wheel 25 ensures that the lifting rope 34 maintains appropriate tension, avoiding relaxation and distortion. At this time, the indicator light is stably hung in place through its hook 331, ensuring that its light source can effectively illuminate the lower passage, providing clear guidance for pedestrians.

[0075] When the indicator light needs to be lifted, the servo motor 21 reverses the rotation of the screw rod 23, driving the lifting nut 26 to move upward. In this process, the limit wheel 25 will rotate counterclockwise, the lifting rope 34 will tighten, and the folding strip 32 will move back to the shaft 314, causing the passage indicator light 4 to gradually rise to the preset height.

[0076] After completing the lifting operation, the system will enter standby state, ensuring that the indicator light remains at a safe height when not needed, reducing interference with daily operations. At the same time, regular inspection and maintenance are also an important part of the use process. The operator needs to regularly check each part of the lifting mechanism 2 to ensure the normal operation of components such as lifting rope 34, limit wheel 25 and servo motor 21, to avoid failure at critical moments.

[0077] In addition, users can also adjust the lighting mode of the indicator light according to actual needs, such as selecting a strong light mode during peak hours to improve the indication effect, and adjusting to a soft mode at night or in a situation with less people flow to avoid visual fatigue. Through these flexible adjustments, the passage indicator light 4 not only improves safety, but also effectively optimizes the use experience.

[0078] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
