Description

Technical Field

[0001] This utility model relates to the field of centipede ladder technology, and in particular to a multi-functional operating platform based on centipede ladder. Background Technology

[0002] Centipede ladders are foldable and telescopic ladders used in power maintenance, high-altitude operations, and construction. Their foldable and telescopic structure allows them to adapt to different heights and complex environments. In practical use, centipede ladders are not only easy to carry and transport, but also allow for the rapid construction of high-altitude work platforms, greatly improving work efficiency and providing a reliable climbing tool for workers at heights.

[0003] The multi-functional operating platform based on the centipede ladder is a device that expands and upgrades the functions of the centipede ladder. Using the centipede ladder as a supporting carrier, by adding functional components, the centipede ladder is transformed from a simple climbing tool into a comprehensive operating platform that integrates multiple functions such as climbing, operation and storage, further meeting the diverse operational needs in high-altitude operations.

[0004] However, existing multi-functional operating platforms for centipede ladders avoid the inconvenience caused by the lack of stable operating space for workers when working at heights by adding a simple platform to the centipede ladder, thus ensuring work safety and efficiency. However, because the simple platform adopts a fixed structural design, it is difficult to adapt to the needs of different heights and work scenarios, and its versatility in complex environments is poor, which limits the application scope of the platform.

The movable pedal mechanism includes a circular pedal, which is located on the outer wall of the column. A circular groove is formed at the top of the circular pedal, and a rubber pad is fixedly connected to the inner side of the groove. The inner side of the rubber pad is slidably connected to the outer wall of the column. An installation groove is formed on the front side of the circular pedal, and a rotating block is slidably connected inside the installation groove. A hinge is fixedly connected to the top left side of the installation groove, and the bottom right side of the hinge is fixedly connected to the top left side of the rotating block. A fixing plate is fixedly connected to the top right side of the rotating block, and the bottom right side of the fixing plate is abutted against the top right side of the circular pedal. Fixing bolts are rotatably connected to the front and rear sides of the top of the fixing plate. A support assembly is provided on the bottom rear side of the circular pedal, and a limit assembly is provided on the bottom front side of the circular pedal.

[0007] As a preferred embodiment of this utility model, the reinforcing mechanism includes a cylinder, the outer wall of which is slidably connected to the inner bottom of a column, a base plate fixedly connected to the bottom of the cylinder, and slots provided on the top left and right sides of the base plate. A ring is fixedly connected to the bottom of the outer wall of the column, and extension plates are fixedly connected to the left and right sides of the ring. A locking plate is slidably connected to the top of the two extension plates on opposite sides, and the bottom of the two locking plates penetrates the extension plates and is slidably connected to the interior of the corresponding slots. A fixing component is provided at the opposite ends of the two extension plates.

[0008] As a preferred embodiment of the present invention, the support assembly includes two support rods, the tops of which are fixedly connected to the bottom left and right sides of the circular pedal, respectively, and the bottoms of the two support rods are fixedly connected to the same support plate, the front side of which is slidably connected to the rear side of the column.

[0009] As a preferred technical solution of this utility model, the limiting component includes two positioning plates. The tops of the two positioning plates are respectively fixedly connected to the bottom left and right sides of the circular pedal. Sliding grooves are provided at both ends of the bottom front side of the circular pedal. Sliding blocks are slidably connected inside the two sliding grooves. Moving plates are fixedly connected to the bottom of the two sliding blocks. Threaded rods are rotatably connected to the front sides of the two moving plates. The rear ends of the two threaded rods pass through the moving plates and the corresponding positioning plates in sequence.

[0010] As a preferred embodiment of the present invention, the fixing component includes two fixing blocks, one adjacent end of the two fixing blocks being slidably connected to the opposite side of the corresponding extension plate, and a fixing groove is provided on one side of both extension plates and the card plate.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by inserting the mounting groove on the front side of the circular pedal into the top of the foot pedal of the corresponding height, and then rotating the rotating block by the hinge, the fixing plate is made to fit the pedal and then tightened with fixing bolts. At the same time, the support rod and support plate of the support component provide rear support, and the limiting component clamps the foot pedal to restrict the circular pedal from sliding back and forth. This allows for height adjustment as needed while maintaining stability and preventing wobbling, thus ensuring the safe operation of the operator.

[0016] 2. In this utility model, the cylinder and the bottom of the column are slidably connected for positioning. The base plate provides basic support. After the ring drives the extension plate to be positioned, the card plate slides along the extension plate and is inserted into the card slot of the base plate to achieve initial fixation. Then, the sliding fixing block is aligned with the fixing slots on the extension plate and the card plate and embedded. Multiple lockings are achieved to realize a stable connection between the column and the base plate, effectively enhancing the overall stability of the platform and resisting external forces to prevent shaking and tipping.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a multi-functional operating platform based on a centipede ladder, including a column 1 as the main support structure of the entire platform. Multiple footrests 2 are equidistantly fixed to the left and right sides of the column 1 for easy climbing. A movable pedal mechanism 3 is provided on the outer wall of the column 1 to adjust the position and status of the pedals. A reinforcement mechanism 4 is provided at the bottom of the column 1 to enhance its stability and prevent the platform from swaying or tilting. The reinforcement mechanism 4 reinforces the column 1 to ensure the safety of the platform during use. The movable pedal mechanism 3 includes a circular pedal 301, providing a flat surface for the operator to stand and work. The circular pedal 301 is located on the outer wall of the column 1 and can slide up and down along the column 1. A circular groove 30 is formed at the top of the circular pedal 301. 2. A rubber pad 303 is used to install the circular pedal 301 and assist it in sliding on the column 1. The inner side of the circular groove 302 is fixedly connected to the rubber pad 303 to increase the friction between the circular pedal 301 and the column 1, while protecting the surface of the column 1. The inner side of the rubber pad 303 is slidably connected to the outer wall of the column 1 to realize the mobility of the circular pedal 301 on the column 1. The front side of the circular pedal 301 has a mounting groove 304 for installing the rotating block 306 and providing it with rotation space. The rotating block 306 is slidably connected inside the mounting groove 304, and the circular pedal 301 can be unfolded and retracted by rotation. A hinge 305 is fixedly connected to the top left side of the mounting groove 304 to provide a rotation shaft for the rotating block 306, allowing it to rotate flexibly. Page 305 is fixedly connected to the bottom right side of the rotating block 306 at the top left, connecting the rotating block 306 to the mounting groove 304 to ensure the stability of the rotating block 306's rotation. A fixing plate 307 is fixedly connected to the top right side of the rotating block 306. After the circular pedal 301 is unfolded, it cooperates with the fixing bolts 308 to fix the circular pedal 301. The bottom right side of the fixing plate 307 fits against the top right side of the circular pedal 301, ensuring a tight connection between the fixing plate 307 and the circular pedal 301. Fixing bolts 308 are rotatably connected to the front and rear sides of the top of the fixing plate 307. By tightening the fixing bolts 308, the fixing plate 307 is fixed to the circular pedal 301, keeping the circular pedal 301 horizontal and stable. A support is provided at the bottom rear side of the circular pedal 301. Component 309 provides rear support for the circular pedal 301. A limit component 310 is provided on the front bottom of the circular pedal 301 to restrict the forward and backward sliding of the circular pedal 301 and ensure its fixed position during use. The support component 309 includes two support rods 3091, which support the rear of the circular pedal 301 and distribute the pressure on the pedal. The tops of the two support rods 3091 are respectively fixedly connected to the left and right bottom sides of the circular pedal 301, connecting the circular pedal 301 to the support plate 3092 and transmitting the support force. The bottoms of the two support rods 3091 are fixedly connected to the same support plate 3092, which slides in contact with the rear side of the column 1 to increase the support area. The front side of the support plate 3092 is slidably connected to the rear side of the column 1, providing support while...The limiting assembly 310 includes two positioning plates 3101, providing a mounting base for the movable plate 3104 and the threaded rod 3105, and assisting in limiting the sliding of the circular pedal 301. The tops of the two positioning plates 3101 are respectively fixedly connected to the left and right sides of the bottom of the circular pedal 301. Sliding grooves 3102 are provided at both ends of the front bottom of the circular pedal 301, providing sliding tracks for the sliding blocks 3103. Sliding blocks 3103 are slidably connected inside both sliding grooves 3102. The movable plate 3104 is driven by sliding within the sliding grooves 3102. The two sliding blocks 3103 are both fixedly connected to the bottom of a movable plate 3104, which cooperates with a threaded rod 3105 to adjust their position and restrict the sliding of the circular pedal 301. The front sides of both movable plates 3104 are rotatably connected to threaded rods 3105. Adjusting the position of the movable plates 3104 via the threads limits the movement of the circular pedal 301. The rear ends of both threaded rods 3105 pass through the movable plate 3104 and the corresponding positioning plate 3101 in sequence, cooperating with the movable plate 3104 and the positioning plate 3101 to limit and fix the circular pedal 301.

[0026] Specifically, the column 1 serves as the main structure, providing vertical support for the entire platform. Equally spaced footrests 2 on its left and right sides facilitate climbing. The circular footrest 301 in the movable footrest mechanism 3 is slidably connected to the column 1 via a rubber pad 303 within the top circular groove 302, allowing for height adjustment along the column 1. The rubber pad 303 provides friction while protecting the surface of the column 1. The rotating block 306 within the mounting groove 304 is flipped via a hinge 305. Combined with the fixing plate 307 and fixing bolts 308, the circular footrest 301 is locked in a horizontal position, forming a stable working plane. The two support rods 3091 and the support plate 3092 of the support assembly 309 are circular... The circular pedal 301 provides rear support and enhances load-bearing capacity. The positioning plate 3101, sliding block 3103, moving plate 3104 and threaded rod 3105 of the limiting assembly 310 limit the forward and backward sliding of the circular pedal 301 through threaded adjustment, further improving stability. The cylinder 401 of the reinforcing mechanism 4 is slidably connected to the bottom of the column 1. The base plate 402 expands the support area. The locking plate 406 on the ring 404 and the extension plate 405 is inserted into the locking groove 403 of the base plate 402 to achieve initial fixation of the column 1 and the base plate 402. The fixing block 4071 of the fixing assembly 407 cooperates with the fixing groove 4072 to further strengthen the connection and prevent the column 1 from shaking or shifting.

[0027] Reference Figure 2 and Figure 5The reinforcement mechanism 4 includes a cylinder 401, which serves as a support and positioning component for the bottom of the column 1. The outer wall of the cylinder 401 is slidably connected to the inner bottom of the column 1, enabling an adjustable connection between the column 1 and the reinforcement mechanism 4. A base plate 402 is fixedly connected to the bottom of the cylinder 401 to increase the contact area with the ground. The top left and right sides of the base plate 402 are provided with slots 403 for engaging with a locking plate 406 to limit the lateral displacement of the column 1. A ring 404 is fixedly connected to the bottom of the outer wall of the column 1, serving as a basic component connecting the locking plate 406 and the extension plate 405, enhancing the structural strength of the bottom of the column 1. Extension plates 405 are fixedly connected to the left and right sides of the ring 404, providing a sliding track for the locking plate 406 and assisting in fixing the locking plate 406. Locking plates 406 are slidably connected to the top of the two extension plates 405 on opposite sides, allowing them to be inserted into the base plate 402. The slot 403 initially fixes the column 1 to the base plate 402. The bottoms of the two plates 406 penetrate the extension plate 405 and slide inside the corresponding slot 403 to form a mechanical locking structure to prevent the column 1 from shaking in the horizontal direction. The two extension plates 405 are provided with fixing components 407 at their far ends to further strengthen the connection between the plates 406 and the extension plates 405. The fixing components 407 include two fixing blocks 4071 for inserting into the fixing slots 4072 to lock the plates 406 a second time. The adjacent ends of the two fixing blocks 4071 are slidably connected to the far side of the corresponding extension plates 405 to facilitate the adjustment of the position of the fixing blocks 4071. The two extension plates 405 and the plate 406 are provided with fixing slots 4072 on one side to cooperate with the fixing blocks 4071 to prevent the plates 406 from accidentally disengaging from the slots 403.

[0028] Specifically, the reinforcement mechanism 4 significantly enhances the stability and support capacity of the column 1 through the synergistic action of its components. The cylinder 401 slides to the bottom inner side of the column 1, providing initial vertical positioning and guidance to ensure the accuracy of the column 1 during installation. The base plate 402, as the basic support structure, disperses the pressure on the column 1 by increasing the contact area with the ground, reducing local pressure and preventing the platform from sinking. The ring 404 at the bottom of the outer wall of the column 1 and the extension plate 405 form a connecting frame. The locking plate 406 slides on the extension plate 405 and inserts into the slot 403 of the base plate 402, forming a constraint to limit the lateral displacement of the column 1 and enhance the anti-overturning ability. The fixing block 4071 in the fixing component 407 cooperates with the fixing groove 4072 on the extension plate 405 and the locking plate 406 to further lock the position of the locking plate 406, preventing it from accidentally dislodging from the slot 403 and ensuring the reliability of the connection.

[0029] Reference Figure 1 , Figure 3 and Figure 4The bottom of the circular pedal 301 is respectively attached to the top of the corresponding foot pedal 2. When the circular pedal 301 is retracted, it can be climbed by using the foot pedal 2, while ensuring the stability of the circular pedal 301 after retraction. The two movable plates 3104 are respectively provided with corresponding foot pedals 2 between them and the corresponding positioning plates 3101. The foot pedals 2 provide space for the adjustment of the movable plates 3104 and do not affect the realization of the limiting function of the circular pedal 301. The two sliding grooves 3102 are provided with sliding grooves 5 on the left and right sides of their interiors, providing sliding tracks for the slider 6 and ensuring the stability of the slider block 3103 sliding in the sliding groove 3102. For qualitative and accurate positioning, sliders 6 are fixedly connected to the left and right sides of the two sliding blocks 3103, which cooperate with the sliding grooves 5 to prevent the sliding blocks 3103 from shifting or getting stuck during sliding. The adjacent ends of the two fixed blocks 4071 are slidably connected to the interior of the corresponding fixed grooves 4072, which facilitates the insertion of the fixed blocks 4071 into the fixed grooves 4072 to further fix the card plate 406. The size of the fixed blocks 4071 matches that of the fixed grooves 4072 to ensure that the fixed blocks 4071 can be tightly embedded in the fixed grooves 4072, thereby enhancing the fixing effect of the fixing components 407 and preventing the connection from becoming loose.

[0030] Specifically, the foot pedal 2 provides mounting support for the circular pedal 301. The moving plate 3104 and the positioning plate 3101 clamp the foot pedal 2, which makes the circular pedal 301 more stable. This provides guidance and constraint for the sliding block 3103 to slide in the sliding groove 3102, ensuring that the sliding block 3103 slides smoothly and preventing it from deviating during the sliding process. The size of the fixing block 4071 matches that of the fixing groove 4072, ensuring that the fixing block 4071 can be tightly inserted into the fixing groove 4072, thereby achieving a firm lock on the card plate 406 and preventing the connection from becoming loose due to excessive gaps, thus enhancing the fixing effect of the fixing component 407.

[0031] Working principle: When using this centipede ladder multi-functional operating platform, first insert the circular step 301 into the top of the footrest 2 at the required height on the column 1 through the mounting groove 304 on the front side. The rubber pad 303 increases the friction with the column 1. After determining the position, rotate the rotating block 306 in the mounting groove 304 through the hinge 305, so that the fixing plate 307 is in contact with the top of the circular step 301. At this time, rotate the fixing bolt 308 through the fixing plate 307 and tighten it on the circular step 301, thereby fixing the rotating block 306 and ensuring the stability of the circular step 301. The two support rods 3091 in the support assembly 309 are fixed to the bottom left and right sides of the circular step 301. On the side, the support plate 3092 at its lower end slides in contact with the rear side of the column 1, providing rear support for the circular pedal 301 and enhancing stability. Two positioning plates 3101 are fixed on the left and right sides of the bottom of the circular pedal 301. The sliding block 3103 slides in the sliding groove 3102 to drive the moving plate 3104 to move. The threaded rod 3105 is rotated so that its rear end passes through the moving plate 3104 and the corresponding positioning plate 3101 in sequence. The position of the moving plate 3104 is adjusted by the threaded engagement to clamp the corresponding foot pedal 2, thereby restricting the forward and backward sliding of the circular pedal 301 and further ensuring the stability of the circular pedal 301 during use, preventing shaking or displacement.

[0032] Furthermore, the outer wall of the cylinder 401 is slidably connected to the inner bottom of the column 1, and the base plate 402 at its bottom provides basic support for the entire structure. When the column 1 is installed on the cylinder 401, the ring 404 at the bottom of the outer wall of the column 1 is positioned accordingly. The extension plates 405 on the left and right sides of the ring 404 provide sliding tracks for the clamping plate 406. The bottom of the clamping plate 406 passes through the extension plate 405 and is inserted into the clamping groove 403 at the top of the base plate 402, thereby realizing the connection between the column 1 and the base plate 402. The two fixing blocks 4071 in the fixing assembly 407 are slidably connected to the side of the extension plate 405 that is away from it. By sliding the fixing blocks 4071, they are aligned with the fixing grooves 4072 on the extension plate 405 and the clamping plate 406, further enhancing the stability of the connection.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
