Description

Technical Field

[0001] This utility model relates to a construction elevator floor safety door, and more particularly to an automatic construction elevator floor safety door system, belonging to the field of building construction technology. Background Technology

[0002] In modern construction sites, construction elevators are indispensable and important equipment, facilitating the vertical transportation of personnel and materials. Construction elevator safety doors, as safety protection devices, are installed at the elevator entrances on each floor. Their main purpose is to ensure that construction personnel cannot enter the elevator shaft before the elevator has come to a complete stop and docked, preventing accidents caused by falling objects from heights.

[0003] Currently, the common safety doors for construction elevators are double doors with bolts between the two doors and safety signs such as "Caution: Close the door after use" on the doors. However, they require manual opening and closing, which is time-consuming and laborious, and there is a high risk of forgetting to close or lock the doors, significantly reducing safety. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an automatic floor safety door system for construction elevators. This system can not only improve the automation and intelligence level of door opening and closing operations, saving manpower and time, but also greatly improve safety.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic floor safety door system for a construction elevator includes a construction elevator and floor safety doors. The floor safety doors include a double-leaf door body, with automatic opening and closing mechanisms symmetrically arranged on both sides of the top of the double-leaf door body. Each automatic opening and closing mechanism has an opening and closing operating component, which is located on the outer side of the double-leaf door body opposite to the construction elevator.

[0007] A sensing component is installed on the lower side of the double-leaf door facing the construction elevator. The sensing component is configured to monitor the presence of the construction elevator and is also connected to the automatic door opening and closing mechanism.

[0008] When the sensing component detects that the construction elevator has left, it sends a closing command to control the automatic door opening and closing mechanism to automatically close the floor safety door; when the sensing component detects that the construction elevator is present, it sends an opening command to the automatic door opening and closing mechanism to control the floor safety door to automatically open.

[0009] As a further optional design of this technical solution, each automatic door opening and closing mechanism includes an electric door opener, and the opening and closing operation component includes a switch button;

[0010] A double-leaf door consists of a door frame and two door panels hinged inside the door frame.

[0011] Each door leaf is equipped with an electric door opener on its outer side, and the door opener transmission rods of the two electric door openers are fixedly connected to the corresponding door leaf.

[0012] As a further optional design of this technical solution, the sensing component adopts a distance sensor with a delay function, and the distance sensor is fixedly installed on the floor beam.

[0013] As a further optional design of this technical solution, a magnetic door lock is also provided on the top of the side of the double-leaf door facing away from the construction elevator. The magnetic door lock is configured to be connected to the automatic door opening and closing mechanism.

[0014] When the double doors are closed, the magnetic door lock is in the locked state; when the double doors are opened, the magnetic door lock is in the unlocked state.

[0015] As a further optional design of this technical solution, an indicator light is also provided on the outer side of the double-leaf door facing away from the construction elevator. The indicator light is configured to be connected to the automatic door opening and closing mechanism and is used to illuminate when the door is opened or when the door fails to close properly.

[0016] Using the above technical solution, this utility model provides an automatic floor safety door system for construction elevators. By setting up an automatic door opening and closing mechanism, and utilizing the cooperation between the switch operation component and the automatic door opening and closing mechanism, one-button operation of opening and closing the safety door is realized. Compared with the manual pushing and pulling method of opening and closing the door, the operation is simpler, the level of automation is higher, and manpower and time are saved. At the same time, by using the sensor component in conjunction with the automatic door opening and closing mechanism, intelligent opening and closing of the safety door is realized, which can further prevent major safety hazards caused by human factors causing the safety door to not close in time, and greatly improve safety.

[0031] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] In the description of this utility model, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0035] Figures 1 to 3 A schematic diagram of a preferred embodiment of the present invention is shown. Figure 1 and Figure 2 An automatic floor safety door system for a construction elevator includes a construction elevator 2 and a floor safety door 1. The floor safety door 1 includes a double-leaf door body 11. Automatic opening and closing mechanisms 12 are symmetrically arranged on both sides of the top of the double-leaf door body 11. The automatic opening and closing mechanism 12 has a switch operation component 13, which is arranged on the outside of the double-leaf door body 11 on the side opposite to the construction elevator 2 (i.e., facade B in the figure).

[0036] See Figure 3A sensing component 14 is provided on the lower side of the side of the double-leaf door 11 facing the construction elevator 2 (i.e., facade A in the figure). The sensing component 14 is configured to monitor the presence of the construction elevator 2. The sensing component 14 is also connected to the automatic door opening and closing mechanism 12. When the sensing component 14 detects that the construction elevator 2 has left, it sends a closing command to control the automatic door opening and closing mechanism 12 to automatically close the floor safety door 1. When the sensing component 14 detects that the construction elevator 2 is present, it sends an opening command to the automatic door opening and closing mechanism 12 to control the floor safety door 1 to automatically open.

[0037] Typically, construction elevators are installed on the exterior of buildings during on-site construction, and floor safety doors 1 need to be installed at each floor. The location of each floor safety door 1 is consistent with that of each construction elevator 2.

[0038] When in use, after the construction elevator 2 arrives at the corresponding floor, the floor safety door 1 is manually opened by switching component 13. When the construction elevator 2 has not left, the sensing component 14 detects the presence of the construction elevator and keeps the floor safety door 1 automatically open.

[0039] Before the construction elevator 2 leaves, the floor safety door 1 can be manually closed by the switch operation component 13; if it is not manually closed due to site reasons, the sensing component 14 detects that the elevator has left and sends a closing command to automatically close the floor safety door 1.

[0040] Therefore, the automatic floor safety door system for construction elevators in this embodiment can prevent major safety hazards caused by human factors leading to the safety door not closing in time, greatly improving safety, and is also easier to operate and has a higher level of intelligence.

[0041] In a further optional embodiment of this example, each automatic door opening and closing mechanism 12 includes an electric door opener 121, and the switch operation component 13 includes a switch button 131; the double-leaf door body 11 includes a door frame 111 and two door leaves 112 hinged inside the door frame 111; an electric door opener 121 is respectively provided on the outside of each door leaf 112, and the door opener transmission rods 1211 of the two electric door openers 121 are respectively fixedly connected to the corresponding door leaves 112.

[0042] In practice, the electric door opener 121 is triggered by the switch button 131, so that the floor safety door 1 can be manually opened or closed by the switch button 131. Compared with the manual push-pull door of the prior art, the operation of the switch button 131 saves manpower and time, and also further improves the safety of construction to a certain extent.

[0043] In a further optional embodiment of this example, the sensing component 14 adopts a distance sensor 141 with a delay function, and the distance sensor 141 is fixedly installed on the floor beam.

[0044] In practice, when the distance sensor 141 detects the presence of the construction elevator 2, it automatically opens the floor safety door 1. Its delay function can prevent the opening command from being triggered when the elevator is moving up or down. When the distance sensor 141 detects that the elevator has left, it sends a closing command to close the safety door through the electric door opener 121.

[0045] In a further optional embodiment of this example, a magnetic door lock 15 is provided on the top of the side of the double-leaf door 11 facing away from the construction elevator 2. The magnetic door lock 15 is configured to be connected to the automatic door opening and closing mechanism 12. When the double-leaf door 11 is closed, the magnetic door lock 15 is in a locked state, and when the double-leaf door 11 is opened, the magnetic door lock 15 is in an unlocked state.

[0046] The magnetic door lock 15 is primarily designed to further enhance the system's security. Specifically, based on the automatic door opening and closing mechanism 12, the first level of manual intelligent door opening and closing is achieved using the switch operation component 13. Then, the second level of automatic intelligent door opening and closing is achieved using the sensing component 14. Finally, the third level of automatic intelligent door locking is achieved using the magnetic door lock 15. This triple-step operation ensures the accurate opening, closing, or locking of the floor safety door 1, effectively preventing major safety accidents caused by the safety door not being closed / locked in time.

[0047] In a further optional embodiment of this example, an indicator light 16 is provided on the outer side of the side of the double-leaf door 11 facing away from the construction elevator 2. The indicator light 16 is configured to be connected to the automatic door opening and closing mechanism 12 for lighting up when the door is opened or when the door fails to close properly.

[0048] The main function of indicator light 16 is to remind the floor safety door 1 that it is in a dangerous open state, requiring caution and necessary safety measures. Compared to text safety signs, it is more intelligent, eye-catching, and timely. For example, indicator light 16 can be designed to be red for a more effective warning, and its position can be set high, such as near the top of the double door 11.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
