Description

Technical Field

[0001] This utility model relates to the field of protective pedal technology, and in particular to a protective pedal for construction elevators. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings are springing up like mushrooms after rain, and the scale and complexity of construction are constantly increasing. As a key piece of equipment for vertical transportation on construction sites, construction elevators bear the heavy responsibility of rapid transfer of personnel and materials.

[0003] In existing technologies, some protective steps are unstable, especially when moving heavy objects, increasing the probability of falling. During material handling, gaps can also cause items to slip into the elevator shaft, leading to safety accidents. Extra care must be taken to avoid gaps when moving heavy objects, reducing transportation efficiency. In addition, operational errors can lead to heavy objects falling or people being injured. Therefore, a construction elevator protective step is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a protective step for construction elevators, aiming to improve the problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A safety tread for construction elevators includes a tread and a base plate. An electric push rod is fixedly connected inside the tread. A sliding block is fixedly connected to the drive end of the electric push rod. Two rotating columns are fixedly connected to the front side of the sliding block. A transmission rod is rotatably connected to the outside of each rotating column. An extension plate is rotatably connected to the other end of each transmission rod. A sliding plate is rotatably connected to the bottom of each transmission rod. A support plate is rotatably connected to the other side of each sliding plate. As a further description of the above technical solution: The rear side of each support plate is rotatably connected to a slider, and the outside of each slider is slidably connected to the inside of a pedal. As a further description of the above technical solution: The pedal has a sliding groove inside, and the extension plate is slidably connected to the inside of the pedal. As a further description of the above technical solution: A protective frame is fixedly connected to the top of the extension plate, and the bottom of the transmission rod is slidably connected to the inner wall of the pedal. As a further description of the above technical solution: The pedal has two grooves inside, and the rear side of the pedal is rotatably connected to the front side of the base plate. As a further description of the above technical solution: An elevator is fixedly connected to the top of the base plate, and a roller shutter door is installed inside the elevator. The sliding block is slidably connected to the inside of the pedal.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Reference Figures 1 to 3This utility model provides an embodiment of a construction elevator safety step, comprising a step 1 and a base plate 6. An electric push rod 4 is fixedly connected inside the step 1. The step 1 ensures that each component moves along a predetermined trajectory and simultaneously bears the load of the extension plate 2 and the protective frame 3 during operation. A sliding block 7 is fixedly connected to the drive end of the electric push rod 4. The electric push rod 4 drives the sliding block 7 to slide within the step 1, precisely controlling the extension and retraction of the extension plate 2 to achieve automated operation. Two sliding grooves 5 are provided inside the step 1. The sliding grooves 5 restrict the direction of component movement, ensuring that the transmission rod 9 slides smoothly along a preset path under the drive of the sliding block 7, ensuring structural stability during the extension and retraction of the extension plate 2. The rear side of the step 1 is rotatably connected to the front side of the base plate 6. The top of the base plate 6 is connected to an elevator 14, and the front side is rotatably connected to the step 1. The entire extension plate 2 mechanism provides stable support. Two rotating columns 8 are fixedly connected to the front side of the sliding block 7. The rotation of the rotating columns 8 causes the transmission rod 9 to rotate around them, converting the linear motion of the sliding block 7 into the rotation of the transmission rod 9 and the lifting and lowering motion of the extension plate 2. The sliding block 7 then drives the transmission rod 9 to move, realizing the extension and retraction of the extension plate 2. This is a key link connecting the power source and the transmission structure. The transmission rod 9 is rotatably connected to the outside of the rotating columns 8. The transmission rod 9 rotates under the drive of the sliding block 7, converting the linear motion into the vertical lifting and lowering of the extension plate 2. At the same time, through cooperation with the sliding plate 10, the other end of the transmission rod 9 is rotatably connected to the extension plate 2. The extension plate 2 extends out of the pedal 1 under the drive of the transmission rod 9, expanding the coverage area of ​​the protective pedal 1, filling the gap between the elevator 14 and the floor, and effectively preventing people or materials from falling.

[0011] A protective frame 3 is fixedly connected to the top of the extension plate 2, forming a vertical protective barrier. After the extension plate 2 extends, it prevents personnel or materials from accidentally slipping, especially when carrying heavy objects or when personnel are moving in and out. The bottom of the transmission rod 9 is slidably connected to the inner wall of the pedal 1. Each bottom of the transmission rod 9 is rotatably connected to a sliding plate 10. The sliding plate 10 assists the transmission rod 9 in transmitting force, making the force on the extension plate 2 more even. At the same time, it plays a guiding and supporting role during the movement of the extension plate 2, enhancing the deformation resistance of the structure. Each other side of the sliding plate 10 is rotatably connected to a support plate 11. The support plate 11, in cooperation with the sliding plate 10 and the slider 12, distributes the weight and working load of the extension plate 2 onto the pedal 1, ensuring the smooth movement of the extension plate 2 and improving the overall strength of the mechanism. Each rear side of the support plate 11 is rotatably connected to a slider 12, which provides a sliding track for the support plate 11. When the extension plate 2 moves, it guides the support plate 11 to slide in a predetermined direction. To ensure the precise and stable movement of the extension plate 2, while also sharing part of the load and preventing structural displacement, the external of the slider 12 is slidably connected to the interior of the pedal 1. The interior of the pedal 1 has a sliding groove 13, which ensures that the slider 12 can only slide in a specific direction. This allows the support plate 11, sliding plate 10, and transmission rod 9 to work together to achieve smooth and reliable extension and retraction of the extension plate 2. The interior of the extension plate 2 is slidably connected to the interior of the pedal 1. The top of the base plate 6 is fixedly connected to the elevator 14, which is linked to the extension plate 2 mechanism. When the elevator 14 stops, the extension plate 2 unfolds to fill the gap between the elevator 14 and the floor. The interior of the elevator 14 is equipped with a roller shutter door 15 to prevent people or materials from falling. When the elevator 14 stops, the roller shutter door 15 opens and cooperates with the unfolded extension plate 2 mechanism to form a safe passage, facilitating the entry and exit of personnel and materials, while also serving as an isolation and protection function. The external of the sliding block 7 is slidably connected to the interior of the pedal 1. Working principle: When the electric push rod 4 is activated, it drives the sliding block 7 to slide in the groove 5 inside the pedal 1. The sliding block 7 drives the rotating column 8, causing the transmission rod 9 to rotate around it, converting the linear motion into the lifting motion of the extension plate 2. The bottom of the transmission rod 9 slides in the sliding groove 13 through the sliding plate 10, support plate 11 and slider 12, dispersing the load and guiding it. The extension plate 2 extends out of the pedal 1, and the top protective frame 3 forms a vertical barrier. When the elevator 14 stops, the roller shutter door 15 opens, cooperating with the extension plate 2 to form a safety passage, realizing automated protection and passage. After the extension plate 2 extends, it can cover the gap between the elevator 14 and the floor, preventing people from stepping into empty spaces or materials from falling. It is especially suitable for carrying heavy objects or scenarios where people frequently enter and exit. Together with the top protective frame 3, it forms a three-dimensional protective barrier, flexibly adapting to different floor height differences or elevator 14 stopping positions, improving the versatility of the protection system.

[0012] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
