Description

Technical Field

[0001] The utility model relates to the technical field of building construction auxiliary equipment, in particular to a semi-automatic pedal type safety protection door. Background Art

[0002] With the rapid development of the construction industry, the safety of high-rise building construction is receiving increasing attention. Elevator shafts, in particular, have become the primary route for transporting materials and personnel during construction. To ensure safety during construction, the gap between elevators and floors has become a critical issue that needs to be addressed. Construction workers often need to navigate the gap between elevators and floors, and without proper protective measures, this gap can pose a serious safety hazard. Furthermore, during construction, construction site carts are often used to transport materials. Excessive gaps not only affect construction efficiency but can also easily cause materials to fall and even lead to accidents. Therefore, effectively filling the gap between elevators and floors to ensure the safe transportation of personnel and materials has become a pressing issue in the construction industry.

[0003] The existing technical solutions mainly include filling the gaps with simple fixed pedals or movable pedals, and setting up protective doors for safety protection. The typical practice is to unfold or fold the pedals manually and manually open and close the protective doors. Although this technology can solve the safety problems in construction to a certain extent, it still has many shortcomings. First of all, the existing pedal structures are mostly fixed or simple rotating pedals, which cannot be flexibly adjusted according to different floors and actual site conditions, and have poor adaptability. In addition, the existing pedal materials are mostly traditional steel plates or wooden boards, which are heavy and inconvenient to operate, which not only increases the labor intensity of construction workers, but also affects work efficiency. Secondly, when the trolley transports materials, the synchronization between the protective door and the pedal is poor, which easily leads to the formation of a gap between the protective door and the pedal. The risk of materials falling still exists, and the safety protection effect needs to be further improved.

[0004] How to solve the above technical problems is the subject faced by this utility model. Utility Model Content

[0018] The fixed shaft, the third bevel gear and the fourth bevel gear are all rotatably connected to the inside of the right-angle piece.

[0019] Sliding channels are symmetrically opened on both sides of the pedal, and an extended pedal is slidably connected in each of the two sliding channels;

[0020] A plurality of circular holes are opened on the opposite side of the two extended pedals, and the circular holes pass through a plurality of sliding rods arranged in parallel in the pedals. A screw is threadedly connected to the opposite side of the two extended pedals, and the threads of the two screw rods are coaxial and symmetrically arranged. The two screw rods are connected to the driving motor at the center of the pedal, and the driving motor drives the switch remotely through the switch.

Several circular holes are opened on the opposite sides of the two extended pedals 3. The circular holes pass through several sliding rods 104 arranged in parallel in the pedal 1. A screw rod 301 is threadedly connected to the opposite side of the two extended pedals 3. The threads of the two screw rods 301 are coaxial and symmetrically arranged. The two screw rods 301 are both connected to the driving motor at the center of the inside of the pedal 1, and the driving motor drives the switch through the switch remote control.

[0038] The protective doors 2 are connected to the two sides of the pedal 1 through a linkage mechanism. The protective doors 2 are connected to the vertical door frames on both sides of the elevator through the second rotating shaft 202. The protective door 2 is made of PC material. The protective door 2 is connected to the second rotating shaft 202 through a right-angle piece 203. In the initial state, the protective door 2 fits with the pedal 1 and is located on the side of the pedal 1 close to the floor.

[0039] The linkage mechanism includes a first bevel gear 103 fixedly connected to the first rotating shaft 101, and two first bevel gears 103 are symmetrically arranged, and are located on both sides of the pedal 1 and are coaxially arranged with the first rotating shaft 101. The linkage mechanism also includes a second bevel gear 201, and two second bevel gears 201 are provided, which are respectively fixedly connected to the bottom ends of the two second rotating shafts 202 and are coaxially arranged with the second rotating shafts 202. Each second bevel gear 201 is meshed with a corresponding first bevel gear 103.

[0040] The protective door 2 includes several horizontally arranged protective rods 204, and the protective rods 204 of the two protective doors 2 are arranged crosswise. The protective rods 204 of the protective door 2 in the initial state are located under the same vertical projection. An extended protective frame 4 is provided at the end of the protective door 2 away from the second rotating shaft 202. The extended protective frame 4 includes several extension rods 401, each extension rod 401 is slidably connected to a protective rod 204, and the end of the extension rod 401 close to the second rotating shaft 202 is threadedly connected to a threaded rod 402, and the threaded rod 402 is rotatably connected to the rod body of the protective rod 204. The other end of the threaded rod 402 is fixed and coaxially connected to a third bevel gear 403, each third bevel gear 403 is meshed with a fourth bevel gear 404, and the fourth bevel gear 404 is fixed and coaxially connected to the fixed shaft 405.

The fixed shaft 405, the third bevel gear 403 and the fourth bevel gear 404 are all rotatably connected to the inside of the right-angle piece 203. An infrared sensor is provided on the inner side of the protective door 2.

[0041] During use, the remote control, mounted on the first rotating shaft 101, first drives the motor, causing the step 1 to rotate downward from its initial vertical position and ultimately form a horizontal connection with the floor. During this process, the step 1 is connected to the bottom of the elevator door frame via the first rotating shaft 101, and the drive motor controls its rotation and deployment. Simultaneously, a linkage mechanism activates, causing the first bevel gear 103, fixed to the first rotating shaft 101, to rotate the meshed second bevel gear 201. The second bevel gear 201 is connected to the protective door 2 via the second rotating shaft 202. As the step 1 unfolds, the protective door 2 automatically and synchronously unfolds outward, forming a protective barrier on both sides to prevent construction workers or materials from accidentally falling.

[0042] To further ensure safety, during the unfolding process of the pedal 1, the extended pedals 3 on both sides thereof begin to slide outwards driven by the internal sliding mechanism. The extended pedals 3 extend smoothly along the sliding channel provided in the pedal 1. Several sliding rods 104 are slidably connected in the sliding channel, so that the sliding of the extended pedals 3 is stable and precise. The main function of the extended pedals 3 is to fill the gap that may be generated between the pedal 1 and the protective door 2, thereby avoiding accidents when construction workers and materials pass through. Each extended pedal 3 is threadedly connected to the screw rod 301 inside the pedal 1. The screw rod 301 is controlled by the internal drive motor to rotate to ensure that the extended pedal 3 can slide smoothly to the predetermined position on both sides. In this way, after the pedal 1 is fully unfolded, the extended pedals 3 on both sides can further fill the gap between the pedal 1 and the protective door 2, ensuring that the structure of the entire pedal and the protective door is tight and seamless, further improving safety.

[0043] The protective door 2 is equipped with several horizontally arranged protective rods 204. When the protective door is deployed, these rods 204 form an effective protective barrier to prevent materials or personnel from falling. An extended protective frame 4 is installed at the far end of the protective door 2. The extension rods 401 are slidably connected to the protective rods 204. The threaded rods 402 and third bevel gears 403 work together to allow the extended protective frame 4 to be deployed or retracted as needed, further enhancing the protective effect of the protective door 2. The entire process is controlled by a remote control switch, ensuring that the opening and closing of the protective door is synchronized with the movement of the pedals, reducing the complexity of manual operation and improving construction efficiency and safety.

[0044] At the same time, a ramp 102 is designed on the surface of the pedal 1 to ensure that the construction site trolley can pass smoothly and reduce obstacles caused by material handling. In addition, a pressure sensor is installed inside the pedal 1. When heavy objects or construction workers pass by, the load condition can be detected in real time to prevent the pedal from being overloaded, further ensuring safety. An infrared sensor is also installed inside the protective door 2. When an approaching person or object is detected, the automatic protection mechanism can be triggered to avoid accidental falls. The entire operation process is simple and convenient. Through the cooperation of semi-automatic control and intelligent sensing equipment, the synchronous movement of the pedal and the protective door is more efficient and safer.
