Abstract
Description
Technical Field
[0001] This utility model belongs to the field of intelligent construction hoists, and specifically relates to a safety flip-door. Background Technology
[0002] Construction hoists are widely used in building construction to transport goods. In recent years, with the development of technology, intelligent construction hoists have begun to be widely used. Compared with conventional construction hoists, intelligent construction hoists do not have a dedicated operator and operate automatically. When the distance between the intelligent construction hoist and the building is slightly far, there are safety hazards for personnel entering and exiting the hoist cage, which can easily lead to accidents. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and provide a safe flip-door that can still meet the needs of personnel to enter and exit safely when the distance between the intelligent construction hoist and the building is relatively large, and does not require special personnel to operate it. The device operates automatically as the cage opens and closes.
[0004] The purpose of this utility model is achieved through the following technical measures: a safety flip-up door, including folding railings, a flip-up door, and a camera. The folding railings are respectively installed on both sides of the double-opening door of the cage. Each folding railing includes a body, a mounting plate, and a first spring. The body is pre-assembled from railing components via connecting pins. The railing components are connected by pins to ensure that each component of the railing rotates flexibly and can be folded or unfolded normally. The body is fixed to the cage by bolts through the upper and lower mounting plates. One end of the first spring is fixed to the vertical part of the folding railing on the outer side, and the other end is fixed to the fixing rod of the lower half of the double-opening door, ensuring that the folding railing can be used safely. During use, the flap door unfolds and folds synchronously with the lower half of the double-leaf door. The flap door includes a flap door body, a mounting base, and a second spring. The mounting base is fixed to the bottom plate of the cage, and the flap door body is hinged to the mounting base. The flap door rests against the double-leaf door and can be opened by its own weight. One end of the second spring is fixed to the flap door body, and the other end is connected to a fixed pull rod. The fixed pull rods are respectively fixed to both sides of the cage to ensure that the flap door opens and closes synchronously with the lower half of the double-leaf door during use. The second spring can effectively reduce the load of the flap door body on the lower half of the double-leaf door, ensuring that the flap door and folding railing can still move synchronously without changing the cage door motor.
[0005] In the above technical solution, the body of the folding railing is pre-assembled from the railing assembly via connecting pins. The railing assembly is equipped with an anti-over-rotation limiting block to prevent the railing from over-rotating due to gravity when it is unfolded.
[0006] In the above technical solution, the camera is installed on the upper frame of the cage and connected to the control system of the elevator to detect in real time whether there are people on the flip door, so as to prevent the elevator from closing the door in advance when someone is on the flip door and causing a safety accident.
[0007] Compared with existing technologies, this utility model of safety flap gate has the following significant advantages: convenient installation, using bolt connections, and easy assembly and disassembly; the folding railings and flap gate open and close synchronously with the double doors of the hoist cage, facilitating personnel entry and exit from the hoist cage while also adding safety railings to the flap gate, meeting the requirements for personnel entry and exit and automatic operation; the hoist cage comes with its own flap gate and folding safety railings, reducing the workload of setting up material unloading platforms and safety railings on the construction site due to the large gap between the hoist cage and the building; a camera is installed on the upper frame of the hoist cage to detect in real time whether personnel are on the flap gate, preventing safety accidents.

[0016] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0019] like Figures 1 to 7 As shown, this embodiment of the utility model provides a safety flip-up door, including a camera, a folding railing 4, and a flip-up door 3. During installation, the camera is mounted on the upper frame of the cage 1 to monitor in real time whether anyone is standing on the flip-up door during use. If anyone is on the flip-up door, the control device will not close the door to prevent safety accidents.
[0020] like Figure 3 As shown, during installation, the fixed tie rods 31 are fixed to both sides of the cage 1. After the flap door body 34 is hinged to the mounting base 33, the mounting base 33 is fixed to the bottom plate of the cage 1. The fixed tie rods 31 are connected to the flap door body 34 by the second spring 32. During use, the flap door 3 opens and closes synchronously by opening and closing the lower half of the double door 2. The second spring 32 can effectively reduce the load of the flap door body 34 on the lower half of the double door 2, ensuring that the flap door 3 and the folding railing 4 can still move synchronously without changing the cage door motor.
[0021] like Figure 4As shown, two folding railings 4 are installed on both sides of the double door of the cage 1. During installation, the folding railing assembly 43 is pre-installed as a whole through the connecting pin 42. Then, the upper and lower mounting plates 41 are fixed to the cage 1 with bolts. The outer railing assembly 43 is connected to the fixed pull rod on the lower half of the double door 2 by the first spring 44, so as to ensure that the folding railing 4 folds and unfolds synchronously with the lower half of the double door 2 during use.
[0022] like Figure 5 As shown, the railing assembly 43 is equipped with an anti-over-rotation limiting block 45 to prevent the railing from over-rotating due to gravity when it is unfolded, thus failing to achieve the protective effect.
[0023] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0024] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
