Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to an intelligent landing door for an unmanned intelligent construction elevator. Background Technology
[0002] During the construction of the building, in order to facilitate construction, a floor door is set at the entrance of each floor, and a cage is set up on the outside, namely an unmanned intelligent construction elevator. The unmanned intelligent construction elevator is used to go up and down to enter any floor.
[0003] In existing technologies, unmanned intelligent construction elevators typically use electromagnetic locks and landing doors linked together, requiring manual opening and closing of the landing doors, which is quite troublesome and may result in forgetting to close the doors, causing the elevator to remain in a state where the landing doors are waiting to be closed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention aims to provide an intelligent landing door for unmanned intelligent construction elevators. By adopting this solution, the landing door can be opened or closed simultaneously when the elevator door is opened or closed, thereby realizing the automatic opening and closing of the landing door.
[0005] This utility model is achieved through the following technical solution:
[0006] A smart landing door for an unmanned intelligent construction elevator, comprising:
[0007] Door frame, which is fixed at the floor entrance / exit;
[0008] A sliding door, which is slidably connected to the door frame and can slide freely up and down; the sliding door is used to partially close the door frame.
[0009] The elevator door of the hoist cage has a first drive assembly for driving the sliding door to slide upward.
[0010] Compared to existing technologies, unmanned intelligent construction elevators typically use electromagnetic locks and door linkages, requiring manual opening and closing of the doors, which is cumbersome and prone to the problem of forgetting to close the doors, leaving the elevator in a state where the doors are left to close. This invention provides an intelligent door for unmanned intelligent construction elevators. This solution allows the landing door to open or close simultaneously with the elevator door, achieving automatic opening and closing. Specifically, the solution includes a door frame located at the floor entrance / exit, with a sliding door mounted on the frame. The sliding door partially closes the frame, allowing it to slide upwards to open the bottom of the frame. Under its own weight, the sliding door slides to the bottom, closing the lower half of the frame for protection. When construction workers need to enter or exit a floor, the elevator door opens upwards, simultaneously moving the sliding door upwards to open the lower half of the frame for worker access. Thus, the opening and closing of the landing door is entirely controlled by the elevator door, achieving intelligent opening and closing without manual intervention, reducing operational steps and increasing safety.
[0011] To ensure sufficient clearance for entry and exit when the floor door is opened, the sliding door includes an inner door and an outer door distributed vertically, both of which are slidably connected to the door frame;
[0012] The first drive assembly is used to drive the outer door to slide upward, and the lower end of the outer door has a second drive assembly for driving the inner door to slide upward. In this solution, the sliding door is configured as an inner door and an outer door, which are distributed vertically and located on the inner and outer sides respectively. In this way, when closed, the inner and outer doors have sufficient height to close. When open, the elevator door first drives the outer door to slide upward. When the lower end of the outer door moves to the position of the inner door, the second drive assembly then drives the inner door to slide upward. When fully open, the outer door and the inner door can completely or partially overlap, thus ensuring that the clearance height for entry and exit below is not less than 1.8m, facilitating the entry and exit of construction personnel.
[0013] As a specific structure of the first driving component, the first driving component includes a first protruding member disposed at the bottom of the elevator cage door and a second protruding member disposed at the bottom of the outer door. The first and second protruding members extend towards each other, and their projections in the lifting direction of the elevator cage overlap. In this solution, when the elevator door opens upward, the first protruding member can move upward synchronously and abut against the lower surface of the second protruding member, thereby driving the outer door to move upward. The first protruding member can be a hook provided with the elevator cage, or it can be additionally set in the form of a plate, etc. It can connect with the second protruding member when moving upward and disengage from the second protruding member when moving downward. When moving downward, the outer door can slide downward under its own weight until the lower part of the door frame is closed.
[0014] As a specific structure of the second extension member, a mounting plate is movably connected to the bottom edge of the outer door. The second extension member is a plate, one end of which is bolted to the mounting plate, and the other end of which extends outward away from the outer door. The mounting plate can be detachably connected to the bottom edge of the outer door, or it can be provided with a sliding groove to allow the bottom edge of the outer door to slide laterally. Thus, if second extension members are provided on both sides of the bottom edge of the outer door, adjustments can be made according to the position of the cage hooks of different construction hoists.
[0015] As a specific structure of the second driving component, the second driving component includes a third protruding member disposed at the lower end of the outer door, the third protruding member extending away from the inner door; the projection portions of the inner door and the third protruding member overlap in the lifting direction of the cage. The third protruding member can be in the form of a plate or similar, disposed at the bottom of the inner side of the outer door. During the upward movement of the outer door, the bottom third protruding member synchronously drives the inner door to slide upward, thereby fully opening the door frame.
[0016] As a specific sliding connection method, both sides of the outer side of the door frame are equipped with slide rail assemblies. The slide rail assembly includes a first slide rail and a second slide rail arranged sequentially in the direction away from the door frame. The first slide rail and the second slide rail are parallel to each other, and the opening directions of the two first slide rails and the two second slide rails are all arranged facing each other.
[0017] Both sides of the inner door are equipped with pulleys for sliding in the first slide rail;
[0018] Both sides of the outer door are equipped with pulleys for sliding in the second slide rail.
[0019] To facilitate the fixing of the first and second slide rails, both sides of the outer side of the door frame are equipped with L-shaped plates, and the first and second slide rails are welded to the inner corners of the L-shaped plates. Both the first and second slide rails are similar to channel steel, with grooves for sliding.
[0020] When closed, to increase the closing height, the first slide rail has a positioning block in the middle, which is used to prevent the lower ends of the inner doors from sliding towards each other. The positioning block restricts the movement of the inner doors, preventing them from sliding further downwards. When closed, the top of the inner door is higher than the top of the outer door, while the bottom of the inner door can be flush with, or higher than, or lower than the bottom of the outer door.
[0021] As a redundancy solution, the projections of the inner door and the outer door in the direction perpendicular to the door frame plane do not coincide.
[0022] As a redundancy solution, the inner door and the outer door overlap in the projection portion perpendicular to the plane of the door frame.
[0023] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0024] 1. This utility model provides an intelligent landing door for an unmanned intelligent construction elevator. With this solution, the landing door can be opened or closed simultaneously when the elevator door is opened or closed, thereby realizing the automatic opening and closing of the landing door.
[0025] 2. This utility model provides an intelligent landing door for an unmanned intelligent construction elevator. In this solution, the sliding door is set as an inner door and an outer door, which are distributed vertically and located on the inner and outer sides respectively. In this way, when closed, the inner door and the outer door have sufficient height to close; and when open, the clearance height for entry and exit below can be ensured to be not less than 1.8m, so as to facilitate the entry and exit of construction personnel.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0036] Example:
[0037] This embodiment provides an intelligent landing door for an unmanned intelligent construction elevator, such as... Figures 1-4 As shown, it includes:
[0038] A smart landing door for an unmanned intelligent construction elevator, comprising:
[0039] Door frame 1, which is fixed at the floor entrance / exit;
[0040] A sliding door 2 is slidably connected to the door frame 1 and can slide freely up and down; the sliding door 2 is used to partially close the door frame 1.
[0041] The elevator door of the hoist cage has a first drive assembly for driving the sliding door 2 to slide upward.
[0042] Compared to existing technologies, unmanned intelligent construction elevators typically use electromagnetic locks and landing doors linked together, requiring manual opening and closing of the landing doors, which is cumbersome and may result in the elevator being left in a state where the landing door is not yet closed. This utility model provides an intelligent landing door for unmanned intelligent construction elevators. With this solution, the landing door can be opened or closed simultaneously when the elevator door is opened or closed, thereby realizing the automatic opening and closing of the landing door. The specific solution includes a door frame 1 installed at the floor entrance / exit, with a sliding door 2 installed on the door frame 1. The sliding door 2 partially closes the door frame 1, allowing it to slide upwards and open the bottom of the door frame 1. Under its own weight, the sliding door 2 slides to the bottom, closing the lower half of the door frame 1 for protection. When construction workers need to enter or exit the floor, the elevator door of the hoist cage (only a portion of the hoist cage is shown in the diagram) opens upwards, simultaneously moving the sliding door 2 upwards to open the lower half of the door frame 1 for workers to enter and exit. In this way, the opening and closing of the floor doors are entirely controlled by the elevator door, achieving intelligent opening and closing without manual intervention, reducing operational procedures and increasing safety.
[0043] To ensure sufficient clearance for entry and exit when the floor door is opened, the sliding door 2 includes an inner door 201 and an outer door 202 distributed vertically, and both the inner door 201 and the outer door 202 are slidably connected to the door frame 1;
[0044] The first driving component is used to drive the outer door 202 to slide upwards, and the lower end of the outer door 202 has a second driving component for driving the inner door 201 to slide upwards. In this solution, the sliding door 2 is configured as an inner door 201 and an outer door 202, which are distributed vertically and located on the inner and outer sides respectively. In this way, when closed, the inner door 201 and the outer door 202 have sufficient height for sealing; while in the open state, the outer door 202 is first driven upwards by the elevator door. When the lower end of the outer door 202 moves to the position of the inner door 201, the second driving component drives the inner door 201 to slide upwards. When fully open, the outer door 202 and the inner door 201 can completely or partially overlap, thus ensuring that the clearance height for entry and exit below is not less than 1.8m, so as to facilitate the entry and exit of construction personnel.
[0045] As a specific structure of the first driving component, the first driving component includes a first protruding member 3 disposed at the bottom of the hoist elevator door and a second protruding member 4 disposed at the bottom of the outer door 202. The first protruding member 3 and the second protruding member 4 extend towards each other, and the projection portions of the first protruding member 3 and the second protruding member 4 overlap in the hoist elevator direction. In this solution, when the elevator door opens upward, the first protruding member 3 can move upward synchronously and abut against the lower surface of the second protruding member 4, thereby driving the outer door 202 to move upward. The first protruding member 3 can be a hook provided with the hoist elevator cage, or it can be additionally set in the form of a plate, etc. It can connect with the second protruding member 4 when moving upward and disengage from the second protruding member 4 when moving downward. When moving downward, the outer door 202 can slide downward under its own weight until the lower part of the closed door frame 1 is closed.
[0046] As a specific structure of the second extension 4, a mounting plate is movably connected to the bottom edge of the outer door 202. The second extension 4 is a plate, one end of which is connected to the mounting plate by bolts, and the other end of which extends outward away from the outer door 202. The mounting plate can be detachably connected to the bottom edge of the outer door 202, or it can be provided with a sliding groove to allow the bottom edge of the outer door 202 to slide laterally. Thus, if the second extension 4 is provided on both sides of the bottom edge of the outer door 202, it can be adjusted according to the position of the cage hook of different construction hoists.
[0047] As a specific structure of the second driving component, the second driving component includes a third protruding member 5 disposed at the lower end of the outer door 202, the third protruding member 5 extending away from the inner door 201; the projection portions of the inner door 201 and the third protruding member 5 in the lifting direction of the cage coincide. The third protruding member 5 can be configured as a plate or similar form, disposed at the bottom of the inner side of the outer door 202. During the upward movement of the outer door 202, the bottom third protruding member 5 synchronously drives the inner door 201 to slide upward, thereby fully opening the door frame 1.
[0048] As a specific sliding connection method, both sides of the outer side of the door frame 1 are equipped with slide rail assemblies. The slide rail assembly includes a first slide rail 6 and a second slide rail 7 arranged sequentially in the direction away from the door frame 1. The first slide rail 6 and the second slide rail 7 are parallel to each other, and the opening directions of the two first slide rails 6 and the two second slide rails 7 are all facing each other.
[0049] Both sides of the inner door 201 are equipped with pulleys for sliding in the first slide rail 6;
[0050] Both sides of the outer door 202 are equipped with pulleys for sliding in the second slide rail 7.
[0051] To facilitate the fixing of the first slide rail 6 and the second slide rail 7, both sides of the outer side of the door frame 1 are equipped with L-shaped plates 8, and the first slide rail 6 and the second slide rail 7 are welded to the inner corners of the L-shaped plates 8. The first slide rail 6 and the second slide rail 7 are similar to channel steel, with grooves for sliding.
[0052] When closed, to increase the closing height, the first slide rail 6 has a positioning block 9 in the middle, which is used to prevent the lower ends of the inner door 201 from sliding towards each other. The positioning block 9 restricts the inner door 201 from continuing to slide downwards. When closed, the top of the inner door 201 is higher than the top of the outer door 202, while the bottom of the inner door 201 can be flush with, or higher than, or lower than the bottom of the outer door 202.
[0053] As a redundancy solution, the projections of the inner door 201 and the outer door 202 in the direction perpendicular to the plane of the door frame 1 do not overlap.
[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
