Description

Technical Field

[0001] This invention relates to the field of multifunctional ladder technology, and in particular to a multifunctional ladder for the maintenance of fire-fighting electromechanical equipment. Background Technology

[0002] When workers repair fire-fighting equipment, they often need to use ladders to work at heights. The use of multi-functional ladders can improve the efficiency of workers' repair work. Traditional multi-functional ladders for fire-fighting equipment repair include a support frame, anti-slip mat, casters, electric telescopic rod, handle, mounting base, movable plate, control switch and limit rod. The advantage of this multi-functional ladder is that the height of the mounting frame can be adjusted by the electric telescopic rod.

[0003] However, due to the lack of a fixed structure on the shelf of this multi-functional ladder, the tools stored in the shelf are easily scattered during the movement, handling or transportation of the ladder. Furthermore, the scattered tools are easily damaged due to mutual collisions, which is not conducive to the promotion and use of this multi-functional ladder. Summary of the Invention

[0004] To address the shortcomings in the aforementioned background technology, this invention proposes a multi-functional ladder for the maintenance of fire-fighting electromechanical equipment, which solves the problem of tools being easily scattered inside the existing multi-functional ladders.

[0010] Furthermore, the limiting adjustment assembly includes a hollow limiting plate, which is fixedly connected to the limiting base. Limiting through holes corresponding to the limiting slider are opened at both ends of the hollow limiting plate. Several second elastic driving members corresponding to the limiting slider are arranged inside the hollow limiting plate. An attitude adjusting member is arranged on one side of the hollow limiting plate, and is fixedly connected to the hollow limiting plate. A transmission plate is fixedly connected to the telescopic end of the attitude adjusting member. The telescopic end of the attitude adjusting member is also provided with a first elastic driving member for driving the transmission plate away from the attitude adjusting member. A flexible connecting pipe connected to a first connecting pipe is provided at the end of the attitude adjusting member away from the transmission plate.

[0011] Furthermore, the protective drive assembly includes a protective cover plate, with a second limiting pressure plate fixedly connected to the end of the protective cover plate away from the height adjustment component for pressing the limiting frame, and a first limiting pressure plate for pressurizing the transmission plate is also provided at the end of the protective cover plate away from the height adjustment component.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1As shown in Embodiment 1, a multi-functional ladder for fire-fighting equipment maintenance includes a ladder body 1. A height adjustment component 2 is fixedly connected to the top of the ladder body 1. The height adjustment component 2 is an electric telescopic rod or a hydraulic cylinder. A storage mechanism 3 is rotatably connected to the telescopic end of the height adjustment component 2. The height of the storage mechanism 3 can be adjusted by the height adjustment component 2. The storage mechanism 3 includes a limiting base 31, a storage component 32 for storing tools, a limiting adjustment component 33 for limiting and adjusting the posture of the storage component 32, a protective drive component 35 for adjusting the height of the storage component 32 in conjunction with the limiting adjustment component 33 and for adjusting the posture of the limiting adjustment component 33, and a limiting screw 34 for fixing the protective drive component 35. The storage component 32 is located inside the limiting base 31, the limiting adjustment component 33 is located at both ends of the limiting base 31, the limiting screw 34 is threadedly connected to both ends of the limiting base 31, and the protective drive component 35 is located at the end of the limiting base 31 away from the height adjustment component 2.

[0024] Example 2 differs from Example 1 in that, as Figure 2 and Figure 3 As shown, in order to improve the storage effect of the storage component 32 on tools, in this embodiment, preferably, the storage component 32 includes a hollow sealed support plate 323. The two ends of the hollow sealed support plate 323 are fixedly connected to limit sliders 325. The two ends of the limit sliders 325 are provided with first connecting pipes 321 corresponding to the limit sliders 325. The first connecting pipes 321 penetrate the limit sliders 325 and the side walls of the hollow sealed support plate 323.

[0025] Furthermore, the hollow sealing support plate 323 is provided with a limiting frame 326 on its side for separating the stored tools. The hollow sealing support plate 323 is also provided with a number of elastic hollow buffer members 327 corresponding to the limiting frame 326 for fixing the stored tools. The elastic hollow buffer members 327 are rubber airbags. The two ends of the elastic hollow buffer members 327 are provided with a second connecting pipe 322 that is connected to the hollow sealing support plate 323. The second connecting pipe 322 passes through the side wall of the hollow sealing support plate 323. The other side of the hollow sealing support plate 323 is provided with a first elastic buffer plate 324, which is a rubber plate or a silicone plate.

[0026] In use, the storage tools are separated by the limiting frame 326, thereby realizing the classified storage of tools. The elastic hollow buffer 327 provides elastic support and pressure for the stored tools, making it easy for users to reliably fix the stored tools.

[0027] Example 3 differs from Example 1 in that, as Figure 2 and Figure 3 As shown, the storage component 32 includes a hollow sealed support plate 323. Limiting sliders 325 are fixedly connected to both ends of the hollow sealed support plate 323. First connecting pipes 321, corresponding to the limiting sliders 325, are provided at both ends of the limiting sliders 325. The first connecting pipes 321 penetrate the limiting sliders 325 and the side walls of the hollow sealed support plate 323. A limiting frame 326, which separates the stored tools, is provided on the side of the hollow sealed support plate 323. Several elastic hollow buffers 327, corresponding to the limiting frames 326, are also provided on the side of the hollow sealed support plate 323 to fix the stored tools. The elastic hollow buffers 327 are silicone airbags. An elastic plastic protective plate is provided on the upper surface of the elastic hollow buffers 327. Second connecting pipes 322, which communicate with the hollow sealed support plate 323, are provided at both ends of the elastic hollow buffers 327 and penetrate the side walls of the hollow sealed support plate 323.

[0028] Example 4 differs from Example 2 in that, as Figure 2 As shown, in order to make the use of the limit adjustment component 33 more reliable, in this embodiment, preferably, the limit adjustment component 33 includes a hollow limit plate 331, the hollow limit plate 331 is fixedly connected to the limit base 31, the two ends of the hollow limit plate 331 are provided with limit through holes 336 corresponding to the limit slider 325, and the hollow limit plate 331 is provided with a plurality of second elastic driving members 337 corresponding to the limit slider 325, the second elastic driving members 337 being springs. The second elastic drive member 337 is provided to create a certain distance between the two sets of storage components 32, making it convenient for users to store and retrieve tools. A posture adjustment member 334 is provided on one side of the hollow limiting plate 331. The posture adjustment member 334 is a piston cylinder. The posture adjustment member 334 is fixedly connected to the hollow limiting plate 331. The telescopic end of the posture adjustment member 334 is fixedly connected to the transmission plate 332. The telescopic end of the posture adjustment member 334 is also provided with a first elastic drive member 333 for driving the transmission plate 332 away from the posture adjustment member 334. The first elastic drive member 333 is a spring. The end of the posture adjustment member 334 away from the transmission plate 332 is provided with a flexible connecting pipe 335 that is connected to the first connecting pipe 321.

[0029] In use, the second elastic drive member 337 supports the limiting slider 325, thereby creating a certain distance between the two sets of storage components 32, which facilitates the user to store and retrieve tools. When the transmission plate 332 moves towards the attitude adjustment member 334 and compresses the attitude adjustment member 334, the air inside the attitude adjustment member 334 is transported into the interior of the hollow sealing support plate 323 through the flexible connecting pipe 335 and the first connecting pipe 321. At this time, the air inside the hollow sealing support plate 323 enters the interior of the elastic hollow buffer member 327 through the second connecting pipe 322, causing the elastic hollow buffer member 327 to inflate and expand. The expanded elastic hollow buffer member 327 reliably fixes the stored tools.

[0030] Example 5 differs from Example 4 in that the limiting adjustment assembly 33 includes a hollow limiting plate 331, which is fixedly connected to the limiting base 31. Both ends of the hollow limiting plate 331 have limiting through holes 336 corresponding to the limiting slider 325. The hollow limiting plate 331 contains several second elastic driving members 337 corresponding to the limiting slider 325. The second elastic driving members 337 are metal springs. One side of the hollow limiting plate 331 has an attitude adjusting member 334, which is a piston hydraulic cylinder. The attitude adjusting member 334 is fixedly connected to the hollow limiting plate 331. The telescopic end of the attitude adjusting member 334 also has a first elastic driving member 333 for driving the telescopic end of the attitude adjusting member 334 to extend. The first elastic driving member 333 is a metal spring. The end of the attitude adjusting member 334 away from the transmission plate 332 has a flexible connecting pipe 335 connected to the first connecting pipe 321.

[0031] Example 6 differs from Example 4 in that, as Figure 2 As shown, in one embodiment, to make the use of the protective drive assembly 35 more reliable, the protective drive assembly 35 preferably includes a protective cover plate 351. A second limiting pressure plate 354 for pressing the limiting frame 326 is fixedly connected to the end of the protective cover plate 351 away from the height adjustment member 2. A first limiting pressure plate 352 for pressing the transmission plate 332 is also provided at the end of the protective cover plate 351 away from the height adjustment member 2. In use, the protective cover plate 351 is reliably fixed by the cooperation of the first limiting pressure plate 352 and the limiting screw 34. A second elastic buffer plate 355 is provided at the end of the second limiting pressure plate 354 away from the protective cover plate 351. The second elastic buffer plate 355 is a rubber plate or a silicone plate. A handle 353 is provided on the side of the protective cover plate 351.

[0032] Furthermore, both the limit base 31 and the protective cover plate 351 are in a "C" - shaped structure. During use, the protective cover plate 351 is placed on the limit base 31. As the distance between the protective cover plate 351 and the limit base 31 continuously decreases, the second limit pressure plate 354 gradually approaches the limit frame 326. With the further movement of the second limit pressure plate 354, pressure is exerted on the limit frame 326, thereby causing the second elastic driving member 337 to be in a compressed state. At this time, several groups of storage components 32 are closely adjacent to each other. Meanwhile, the first limit pressure plate 352 presses down on the transmission plate 332, thereby squeezing the attitude adjustment member 334. At this time, the air in the attitude adjustment member 334 is filled into the interior of the elastic hollow buffer member 327, causing the elastic hollow buffer member 327 to inflate and expand. The stored tools are reliably fixed by the inflated elastic hollow buffer member 327, thus preventing the stored tools from being scattered.

[0033] Embodiment 7, the difference from Embodiment 6 is that the protective driving component 35 includes a protective cover plate 351. At one end of the protective cover plate 351 away from the height adjustment member 2, a second pressure cylinder for pressing on the limit frame 326 is fixedly connected. At one end of the protective cover plate 351 away from the height adjustment member 2, a first pressure cylinder for pressing on the transmission plate 332 is also provided.

[0034] Embodiment 8, the difference from Embodiment 6 is that, as Figure 2 shown, in order to facilitate the user to reliably fix the limit base 31, in this embodiment, preferably, a limit sleeve 38 slidably connected to the height adjustment member 2 is provided on one side of the limit base 31. A connecting plate 36 corresponding to the limit base 31 is fixedly connected to the side surface of the limit sleeve 38. The connecting plate 36 is fixedly connected to the limit base 31. One end of the limit sleeve 38 is threadedly connected with a fastening screw 37 corresponding to the height adjustment member 2.

[0035] Embodiment 9, the difference from Embodiment 1 is that, as Figure 1 shown, in order to make the use of the ladder more reliable, in this embodiment, preferably, a reinforcing plate 5 for reinforcement is provided at the bottom of the ladder body 1. Elastic protective plates 6 for anti - slip and shock absorption are provided at both ends of the lower surface of the reinforcing plate 5. The elastic protective plates 6 are rubber plates or silicone plates.

[0036] Embodiment 10, the difference from Embodiment 1 is that, as Figure 1 shown, in order to make the functions of the ladder more diverse, in this embodiment, preferably, a warning member 4 for warning is provided on the side surface of the ladder body 1. The warning member 4 is a flashing warning light or an LED display screen. During use, a warning effect is achieved through the warning member 4 to prevent someone from hitting the ladder.

[0037] Working principle and usage process of this invention:

[0038] Before use, loosen the fastening screw 37 with a wrench, then rotate the limiting base 31 90°, and then tighten the fastening screw 37 with a wrench to reliably fix the limiting base 31. The user loosens the limiting screw 34 by hand, then removes the protective drive component 35 by hand, and places the tools to be stored inside the limiting frame 326. The limiting frame 326 achieves the classification and storage of tools through its limiting function, and the use of the elastic hollow buffer 327 provides support for the stored tools.

[0039] After the tools are stored, the protective cover 351 is placed on the limiting base 31. As the distance between the protective cover 351 and the limiting base 31 decreases, the second limiting pressure plate 354 gradually moves closer to the limiting frame 326. With the further movement of the second limiting pressure plate 354, it applies pressure to the limiting frame 326, causing the second elastic drive member 337 to be in a compressed state. At this time, several sets of storage components 32 are close together. At this time, both the first elastic buffer plate 324 and the second elastic buffer plate 355 apply pressure to the stored tools. Simultaneously, the first limiting pressure plate... The downward movement of 352 presses down on the transmission plate 332, causing the attitude adjustment component 334 to be squeezed. At this time, the air inside the attitude adjustment component 334 fills the interior of the elastic hollow buffer component 327, causing the elastic hollow buffer component 327 to inflate. The expanded elastic hollow buffer component 327, together with the first elastic buffer plate 324, the second elastic buffer plate 355, and the limiting frame 326, reliably prevents the stored tools from moving and avoids collisions between them. Then, the user loosens the limiting screw 34 by hand to reliably fix the protective cover plate 351.

[0040] When a user needs to retrieve a stored tool, the user loosens the limit screw 34 by hand and then removes the protective drive assembly 35. At this time, the storage assembly 32 and the limit adjustment assembly 33 return to their initial positions, and the user can directly take out the categorized and stored tools, making it convenient for the user to store and retrieve tools.

[0041] The invention stores tools by means of multiple interconnected structures, which also buffer and reliably secure the stored tools, effectively preventing them from becoming scattered and avoiding damage due to collisions (e.g., scratches on the insulating outer layer). Furthermore, the invention has anti-slip and warning functions, and its simple structure and ease of use make it worthy of promotion and application.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
