Description

Technical Field

[0001] This utility model relates to the field of bridge pier warning sign maintenance technology, and in particular to an auxiliary device for warning sign maintenance. Background Technology

[0002] In the field of waterway and bridge safety management, bridge pier warning signs play a crucial role in ensuring safe navigation for ships. However, current maintenance facilities for bridge pier warning signs generally suffer from systemic defects, particularly in the structural safety and operability of maintenance platforms. Existing maintenance facilities typically employ simple climbing structures or fixed supports, whose design fails to adequately consider safety requirements in complex working environments such as high-altitude and water-adjacent conditions. Maintenance personnel must climb without effective fall protection devices, posing an extremely high risk of accidental falls. Furthermore, the structural layout of existing facilities is disconnected from ergonomic design, with unreasonable climbing paths and uneven distribution of support points, leading to excessive physical exertion and low movement efficiency for maintenance personnel. These structural defects not only significantly extend the time required for cleaning, inspecting, or replacing signs but also exacerbate operational hazards in inclement weather or emergency repair scenarios. Therefore, we provide a warning sign maintenance auxiliary device to address these issues. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 — Figure 9 The example shown.

[0033] This application provides a warning sign maintenance auxiliary device, which includes a first platform 100, a first ladder 200, a handrail 300, and a protective cage 400.

[0034] In some specific embodiments, a fence 110 is provided at the edge of the first platform 100, the first ladder 200 is located on one side of the first platform 100, the handrail 300 is fixedly provided on both sides of the first ladder 200, and the safety cage 400 is fixedly installed on the first ladder 200, and the safety cage 400 and the first ladder 200 define a safety space 401.

[0035] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, when maintenance work on warning signs is required, workers can climb up the first ladder 200 to reach the first platform 100. On the first platform 100, workers can inspect, clean, repair, or replace equipment such as battery boxes, navigation lights, and solar panels installed there, thereby ensuring the normal operation and safety function of the warning signs.

[0036] It should be noted that both the first platform 100 and the first ladder 200 are firmly installed and fixed to a building, such as a bridge pier. This embodiment mainly uses a bridge pier as an example for illustration, but it should be understood that the auxiliary device disclosed in this application can also be applied to other building structures that require similar maintenance operations, and the specific application scenarios are not limited to this.

[0037] Regarding the installation of the safety cage 400, in one feasible implementation, the safety cage 400 can be continuously installed along the entire height range of the first ladder 200. Alternatively, based on actual safety risk assessment, the safety cage 400 can also be selectively installed only in the upper half of the first ladder 200. This embodiment considers the relatively low risk and low probability of fall in the bottom climbing area, therefore, the preferred approach is to install the safety cage 400 only in the upper half of the ladder. Of course, in practical applications, the specific coverage area of ​​the safety cage 400 can be flexibly determined and adjusted according to the working height, environmental conditions, and safety regulations; no single limitation is made here.

[0038] Please continue reading. Figure 1 As shown, during the ascent of the first ladder 200, workers can grip the handrails 300 fixed to both sides of the ladder, thus obtaining stable auxiliary support points and leverage points. With the assistance of the handrails 300, workers can steadily climb upwards and pass through the safety space 401 defined by the safety cage 400, finally reaching the first platform 100 safely. Given that the first platform 100 is usually located at a high position, to provide sufficient safety protection, continuous railings 110 are installed around the edge of the platform to effectively prevent workers from accidentally falling while working on the platform and ensure their personal safety.

[0039] Please continue reading. Figure 1 and Figure 2 As shown, the sign frame structure used to install warning signs is typically located directly below the first platform 100. This sign frame itself is directly fixed to the main structure of the bridge pier. To enhance the overall structural stability and load-bearing capacity of the first platform 100, it is usually also fixedly connected to the sign frame structure below. This connection method significantly increases the supporting force on the first platform 100, further improving the safety and reliability of the entire first platform 100 in high-altitude working environments.

[0040] In some specific examples, the first ladder 200 includes two parallel ladder beams 210, with multiple steps 220 evenly spaced between the two ladder beams 210 along the height direction. Each ladder beam 210 is fixedly equipped with a handrail 300, and a connector 230 is fixedly provided on the side of the ladder beam 210 away from the handrail 300. A fixing plate 240 is provided at the end of the connector 230 away from the direction of the ladder beam 210.

[0041] Please see Figure 5 As shown, each ladder beam 210 is uniformly fixed with multiple connectors 230 along its height direction. Each connector 230 has a fixing plate 240 fixedly installed at the end away from the ladder beam 210. These fixing plates 240 are used to firmly fix the ladder beam 210 to the bridge pier structure.

[0042] During installation, the following methods can be used to connect the fixing plate 240 to the pier: one method is to pre-embed bolts when the pier concrete is poured, and then fasten the fixing plate 240 to the pier surface using the pre-embedded bolts; another method is to drill holes in the pier to form installation holes, and then use expansion bolts or chemical anchors (i.e., chemical bolts) to pass through the fixing plate 240 and anchor it in the holes, thereby achieving a reliable connection between the fixing plate 240 and the pier.

[0043] The aforementioned connection method secures the fixing plate 240 to the pier, thereby firmly fixing the entire ladder beam 210 and its auxiliary structures to the main structure of the pier. This fixing method effectively prevents any relative movement or swaying between the ladder and the pier during use, ensuring the overall stability of the structure and operational safety.

[0044] During the climb, staff members use the step bar 220 set between the two ladder beams 210 and hold the handrails 300 on both sides to provide support and balance, thus achieving a safe and stable upward climbing action.

[0045] In some specific embodiments, the step bar 220 includes a round tube 221 fixedly connected to the ladder beam 210, and a square tube 222 is fixedly provided on the circumference of the round tube 221. The upper surface of the square tube 222 is provided with a plurality of anti-slip grooves 223.

[0046] Please see Figure 7 As shown, in this application, multiple connectors 230 are uniformly fixed along the height direction on each ladder beam 210, and a fixing plate 240 is fixedly installed on the end of each connector 230 away from the ladder beam 210. Each fixing plate 240 is fixedly connected to the pier. Specifically, the fixing plate 240 can be fixed to the pier by pre-embedding bolts in the pier, or by making holes in the pier and then fixing the fixing plate 240 to the pier using expansion bolts or chemical bolts. This fixes the ladder beam 210 and prevents it from moving relative to the pier. It is understood that workers can step on the step bar 220 between two ladder beams 210 and hold the handrails 300 on both sides to climb upwards.

[0047] In one embodiment, the handrail 300 includes a handrail tube 310, with a first connecting tube 320 and a second connecting tube 330 fixedly connected to both ends of the handrail tube 310, the first connecting tube 320 being fixedly connected to the top end of the ladder beam 210, and the second connecting tube 330 being fixedly connected to the bottom end of the ladder beam 210.

[0048] Please see Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8As shown, the handrail 300 is composed of a handrail tube 310, a first connecting tube 320, and a second connecting tube 330, and the combination of the three presents a U-shaped structure. The first connecting tube 320 is fixedly connected to the top of the ladder beam 210, and the second connecting tube 330 is fixedly connected to the bottom of the ladder beam 210.

[0049] Through this specific connection method, the entire handrail 300 structure actually serves as a reinforcing member of the ladder beam 210. This U-shaped handrail structure can effectively improve the bending stiffness and load-bearing capacity of the ladder beam 210 itself, thereby significantly enhancing the overall structural strength and stability of the ladder beam 210.

[0050] When workers are climbing, they can grip the handrail 310 with both hands. This gripping action not only provides additional leverage and balance support during the climbing process, further improving the stability and controllability of the climbing action, but also enhances the overall safety performance of the ladder during operation through the aforementioned structural reinforcement.

[0051] See Figure 2 and Figure 9 As shown, in another embodiment, the handrail 300 is a U-shaped tube, and the ladder beam 210 is provided with multiple U-shaped tubes spaced apart along the height direction.

[0052] In some specific embodiments, the cage 400 includes a surrounding panel 410 and a reinforcing plate 420. The surrounding panel 410 is arranged sequentially and spaced apart on two ladder beams 210 along the height direction. The reinforcing plate 420 is connected sequentially to the periphery of each reinforcing plate 420 along the height direction. The multiple surrounding panels 410 and the first ladder 200 define a safety space 401.

[0053] Please see Figure 6 As shown, a safety space 401 is formed by multiple enclosures 410 arranged along the height direction. This space can support the back of the person and block the body when the person's hands are slippery, thus preventing falls. In order to improve the connection strength of each enclosure 410, a reinforcing plate 420 is used to connect the enclosures 410, so that each enclosure 410 forms a whole, thereby enhancing the strength of the entire cage 400.

[0054] In some specific embodiments, the warning sign maintenance auxiliary device also includes a fall arrestor 500, which includes a mounting frame 510 and a fall arrestor 520. The mounting frame 510 is disposed above the first platform 100, and the fall arrestor 520 is mounted on the mounting frame 510.

[0055] Please see Figure 3As shown, when workers climb onto the first platform 100 and are maintaining the equipment, in order to prevent them from falling through the gaps in the fence 110, a mounting frame 510 fixedly connected to the bridge pier is installed above the first platform 100, and a fall arrestor 520 is installed on the mounting frame 510. After reaching the first platform 100, workers should connect the back of their safety belt to the fall arrestor 520 to prevent accidents. It should be noted that the fall arrestor 520 is an existing component, and its specific structure will not be described in detail here.

[0056] For example, the mounting bracket 510 can be fixedly connected to the bridge pier using chemical bolts or expansion bolts.

[0057] In some specific embodiments, a second platform 600 is provided below the first ladder 200, and a second ladder 700 is provided on one side of the second platform 600. The bottom of the first ladder 200 and the top of the second ladder 700 are respectively located on opposite sides of the second platform 600.

[0058] Please see Figure 4 As shown, for the first platform 100, which is positioned too high, relying solely on the first ladder 200 may not be sufficient to meet the needs of personnel access. To solve this problem, the first ladder 200 and the second ladder 700 can be combined to form a climbing path leading to the higher location.

[0059] Considering the significant physical exertion of climbing long ladders continuously, and the potential safety risks due to exhaustion, this embodiment includes a second platform 600 at the junction of the first ladder 200 and the second ladder 700. This second platform 600 provides a safe area for workers to rest and recover, effectively reducing the probability of accidents caused by fatigue.

[0060] Furthermore, the bottom entrance of the first ladder 200 and the top exit of the second ladder 700 are respectively located on opposite sides of the second platform 600. This layout design has multiple advantages: if a worker accidentally falls while climbing the first ladder 200, the second platform 600 directly below can act as a buffer, significantly reducing the severity of the fall; and by staggering the two ladder sections on both sides of the second platform 600, the continuity of the climbing height is visually effectively divided. When climbing one section, the worker will not directly face the entire height of the other ladder section. This visual division helps to reduce the intuitive perception of the total height, thereby alleviating the psychological fear caused by working at height and improving the worker's confidence and operational stability.

[0061] It should be noted that in this embodiment, the second ladder 700 and the first ladder 200 have the same structure. The specific structure of the second ladder 700 will not be described in detail here. The process of climbing to the second platform 600 via the second ladder 700 is the same as the process of climbing to the first platform 100 via the first ladder 200.

[0062] The working process of this utility model is as follows: The staff first climbs to the second platform 600 via the second ladder 700, and takes a short rest on the platform to relieve physical exertion; then, they continue to climb upward via the first ladder 200: holding the handrails 300 fixed on both sides of the ladder beam 210 with both hands, and stepping on the footboards 220 with both feet; during the climbing process, the staff's body is always within the safety space 401 defined by the cage 400, which forms a barrier on the back of the body to prevent backward fall.

[0063] Upon arrival at the first platform 100, the staff will connect the safety belt to the fall arrestor 520 of the fall arrestor assembly 500 and perform maintenance work on equipment such as the battery box and navigation lights on the first platform 100; at this time, the fence 110 will surround the edge of the platform to provide fall protection.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
