Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering. More specifically, the utility model relates to a flap assembly for an intelligent driverless construction elevator. Background Art
[0002] External construction elevators are the most commonly used vertical transportation equipment for personnel and materials in the domestic and foreign construction industries at present. According to relevant national and local regulations, the distance between the construction elevator and the structural edge must be ensured to be within 100 mm. However, due to design reasons, some housing construction projects or commercial projects will add lines with different overhanging dimensions on the outer facades of each floor of the structure, or there will be short-distance overhanging beam slabs and other structures on the lower several floors of the tower, resulting in the gap between the structure and the construction elevator on some floors not meeting the requirement of not being greater than 100 mm.
[0003] There are usually three ways to solve the above problems. One way is to add a flap inside the elevator cage without changing the structural construction sequence; the second way is to leave the lines or cantilever structures protruding from the elevator running part for construction after the construction elevator is removed during the early-stage structural construction; the third way is to set up an overhanging passage and protection on the floors where the gap between the structure and the construction elevator is greater than 100 mm. Traditional construction elevators generally adopt the first way, that is, the elevator driver operates the flap switch inside the car, but for an intelligent driverless construction elevator, since there is no driver inside during operation, the first way cannot be directly applied to realize the manual flap switch operation. Using the third way will increase additional costs and has a greater safety risk. Therefore, the commonly used way in the early stage is the second way, but this way will prolong the project duration and increase certain secondary construction costs, which is not conducive to project management.
[0004] With the gradual popularization of intelligent construction in the construction industry, at present, intelligent driverless construction elevators have gradually begun to be used in some areas. Under the background of applying intelligent driverless construction elevators, it becomes particularly important to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a flap assembly for an intelligent driverless construction elevator, which has a simple structure. When working, the flap automatically flips with the opening and closing of the landing door of the elevator cage, without the need to set up an additional power mechanism, and can effectively solve the problem that the flap cannot be manually switched on and off when entering the elevator cage from the outside during the operation of the intelligent driverless construction elevator.
[0006] To achieve these and other advantages of the present utility model, there is provided a flap assembly for an intelligent driverless construction elevator, comprising:
[0007] A flap, one end of which is rotatably connected to the elevator cage;
[0008] An elastic member, the two ends of which are respectively rotatably connected to the inner wall of the elevator cage and the flap.
[0009] Wherein, when the landing door of the elevator cage is closed, the other end of the flap abuts against the inner side of the lower landing door of the elevator cage, and at this time the elastic member is in a compressed state; when the landing door of the elevator cage is opened, the other end of the flap rests on the floor.
[0010] The beneficial effects of the present utility model are as follows: In the flap assembly of the present utility model, based on the fact that when the landing doors of the intelligent driverless construction elevator are opened and closed, the upper landing door and the lower landing door approach or move away from each other, so as to realize the closing or opening of the landing doors. When the landing door of the elevator cage is closed, the elastic member is compressed, providing an elastic force towards the lower landing door to the flap. At this time, the flap rotates towards the lower landing door under the action of the elastic member until the other end of the flap abuts against the inner side of the lower landing door. At this time, through the action of the elastic member on the lower landing door, the flap can be ensured to stably lean against the lower landing door. When the landing door of the elevator cage is opened, the upper landing door and the lower landing door move upward and downward respectively. During the downward movement of the lower landing door, the flap continues to rotate outward under the action of the elastic member until the other end of the flap rests on the floor. When the landing door is closed, the lower landing door moves upward, and it will abut against the flap and gradually lift it during the movement. When the landing door is closed, the other end of the flap returns to abut against the inner side of the lower landing door. During the opening and closing process of the landing door of the elevator cage, the flap rotates synchronously with the lifting of the lower landing door, so as to realize the automatic unfolding and storage of the flap. When the staff needs to enter the interior of the elevator cage of the intelligent driverless construction elevator from the outside, there is no need to manually open and close the flap or set up an additional power mechanism. After the landing door is opened, the flap can be unfolded, and after the landing door is closed, the flap is automatically stored inside the elevator cage. When the flap assembly of the present utility model is applied to a tower building with prominent lines or short cantilever structures in terms of structure, after using the automatic flap tool, the prominent lines or short cantilever structures at the elevator running part can be constructed together with the main body at one time, and the forming quality effect is better; compared with the secondary construction method of the lines and short cantilever structures at the elevator running part, it can greatly shorten the construction period of the secondary construction and reduce the construction cost of the secondary construction.
[0011] On the basis of the above technical solutions, the present utility model can also be improved as follows:
[0012] Further, in the flap assembly for an intelligent driverless construction elevator, connecting angle irons are respectively arranged on both sides of the flap, a core column is connected to the connecting angle iron, and bearing seats are respectively arranged on both side walls of the elevator cage, and the core column is rotatably connected to the bearing seat.
[0013] The beneficial effects of adopting the above further solution are as follows: In this further solution, the connecting angle irons on both sides of the flap fix the core column, and the core column extends into the inner ring of the bearing seat and is fixedly connected thereto, realizing the rotational connection between the connecting angle iron and the bearing seat, thereby realizing the rotational connection between the flap and the elevator cage.
[0014] Furthermore, in the flap assembly for an intelligent driverless construction elevator, a first connecting member is provided on one side wall of the elevator cage, a second connecting member is provided on one side of the flap, and the elastic member is arranged between the first connecting member and the second connecting member and is rotatably connected to both of them respectively.
[0015] The beneficial effects of adopting the above further solution are as follows: In this further solution, both ends of the elastic member are rotatably connected to the first connecting member and the second connecting member respectively. While the elastic member is stretched or compressed, the elastic member can rotate together with the rotation of the flap.
[0016] Furthermore, in the flap assembly for an intelligent driverless construction elevator, connecting shafts are provided on both the first connecting member and the second connecting member, and connecting rings are provided at both ends of the elastic member. The connecting rings are rotatably sleeved on the connecting shafts.
[0017] The beneficial effects of adopting the above further solution are as follows: In this further solution, by rotatably sleeving the connecting rings on the connecting shafts, the rotational connection between both ends of the elastic member and the first connecting member and the second connecting member is realized through the rotational connection between the connecting rings and the connecting shafts.
[0018] Furthermore, in the flap assembly for an intelligent driverless construction elevator, rollers are respectively provided on both sides at the other end of the flap. When the landing door of the elevator cage is closed, the rollers abut against the inner side of the lower landing door of the elevator cage.
[0019] The beneficial effects of adopting the above further solution are as follows: In this further solution, rollers are provided on the flap. When one end of the flap contacts the inner side of the lower landing door, the flap is connected to the lower landing door through the rollers, avoiding damage to the flap caused by hard contact between the flap and the lower landing door.
[0020] Furthermore, in the flap assembly for an intelligent driverless construction elevator, two chutes corresponding to the two rollers are respectively provided on the inner side of the lower landing door of the elevator cage.
[0021] The beneficial effects of adopting the above further solution are as follows: In this further solution, by providing chutes on the inner side of the lower landing door, when one end of the flap contacts the inner side of the lower landing door, the rollers are slidably arranged in the chutes. Through the limitation of the chutes on the rollers, the stability when the flap contacts the lower landing door is ensured.
[0022] Furthermore, in the flap assembly for an intelligent driverless construction elevator, the elastic member is a high-performance spring.
[0023] The beneficial effects of adopting the above further solution are as follows: In this further solution, the high-performance spring has excellent elastic properties, can withstand large deformations and loads, and will not easily lose its elasticity.
[0024] Furthermore, in the flap assembly for an intelligent driverless construction elevator, the flap is made of steel plate.
[0025] The beneficial effects of adopting the above further solution are as follows: In this further solution, the flap made of steel plate can ensure the strength of the flap.
[0026] Furthermore, in the flap assembly for an intelligent driverless construction elevator, the flap is of a hollow structure.
[0027] The beneficial effects of adopting the above further solution are as follows: In this further solution, since the steel plate has a relatively large density, if the area of the flap is large, its own weight will also be large, which may cause too large a force on the lower door when the flap is placed on the lower door, and may affect the stability of the lower door. At this time, a plurality of hollow holes are provided on the flap, so that the flap is of a hollow structure, and on the premise of ensuring strength, the self-weight of the flap is reduced.
[0028] Furthermore, in the flap assembly for an intelligent driverless construction elevator, both sides of the flap are connected to the inner wall of the elevator cage through the elastic members.
[0029] The beneficial effects of adopting the above further solution are as follows: In this further solution, elastic members are provided on both sides of the flap and connected to the inner wall of the elevator cage, which can better ensure the stability of the connection between the flap and the inner wall of the elevator cage.

[0038] The following further describes the present utility model in detail with reference to embodiments, so that those skilled in the art can implement it according to the text of the specification.
[0039] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by terms such as "horizontal", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0040] As Figures 1 - 4 shown, the embodiment of the present utility model provides a flap assembly for an intelligent driverless construction elevator, including:
[0041] A flap, one end of which is rotatably connected to the elevator cage;
[0042] An elastic member, both ends of which are respectively rotatably connected to the inner wall of the elevator cage and the flap;
[0043] Among them, when the layer door of the elevator cage is closed, the other end of the flap abuts against the inner side of the lower layer door of the elevator cage, and at this time the elastic member is in a compressed state; when the layer door of the elevator cage is opened, the other end of the flap rests on the floor.
[0044] In this embodiment, one end of the flap is rotatably connected to the elevator cage and is connected by an elastic member. The elastic member provides a force to the flap through its expansion and contraction. Based on the intelligent driverless construction elevator, when the landing door opens and closes, the upper landing door and the lower landing door approach or move away from each other, so as to realize the closing or opening of the landing door. When the landing door of the elevator cage is closed, the elastic member is compressed and provides an elastic force towards the lower landing door to the flap. At this time, the flap rotates towards the lower landing door under the action of the elastic member until the other end of the flap abuts against the inner side of the lower landing door. At this time, through the force of the elastic member on the lower landing door, it can ensure that the flap leans stably against the lower landing door. When the landing door of the elevator cage is opened, the upper landing door and the lower landing door move upward and downward respectively. During the downward movement of the lower landing door, the flap continues to rotate outward under the action of the elastic member until the other end of the flap rests on the floor. It should be noted that the elastic member can be in the original length, compressed state or stretched state at this time. When the elastic member is in the stretched state, the force of the elastic member on the flap is a pulling force towards the elevator cage, and its magnitude needs to ensure that it will not drive the flap to rotate towards the elevator cage, so as to ensure that the other end of the flap can rest stably on the floor. When the landing door is closed, the lower landing door moves upward, and it will abut against the flap and gradually push it up during the movement. When the landing door is closed, the other end of the flap returns to abut against the inner side of the lower landing door. During the opening and closing process of the landing door of the elevator cage, the flap rotates synchronously with the lifting and lowering of the lower landing door, so as to realize the automatic unfolding and storage of the flap. When the staff needs to enter the interior of the elevator cage of the intelligent driverless construction elevator from the outside, there is no need to manually open and close the flap or set up an additional power mechanism. After the landing door is opened, the flap can be unfolded, and after the landing door is closed, the flap is automatically stored inside the cage.
[0045] Preferably, as another embodiment of the present invention, connecting angle irons are respectively arranged on both sides of the flap, a core column is connected to the connecting angle iron, and bearing seats are respectively arranged on both side walls of the elevator cage, and the core column is rotatably connected to the bearing seat.
[0046] In this embodiment, the connecting angle irons on both sides of the flap fix the core column, and the core column extends into the inner ring of the bearing seat and is fixedly connected to it, realizing the rotational connection between the connecting angle iron and the bearing seat, so as to realize the rotational connection between the flap and the elevator cage.
[0047] Preferably, as another embodiment of the present invention, a first connecting member is arranged on one side wall of the elevator cage, a second connecting member is arranged on one side of the flap, and the elastic member is arranged between the first connecting member and the second connecting member and is rotatably connected to both of them respectively. Connecting shafts are arranged on both the first connecting member and the second connecting member, and connecting rings are arranged at both ends of the elastic member, and the connecting rings are rotatably sleeved on the connecting shafts.
[0048] In this embodiment, both ends of the elastic member are rotatably connected to the first connecting member and the second connecting member respectively. While the elastic member is being stretched or compressed, the elastic member can rotate together with the rotation of the flap. By rotatably sleeving the connecting ring on the connecting shaft, the rotational connection between the two ends of the elastic member and the first connecting member and the second connecting member is realized through the rotational connection between the connecting ring and the connecting shaft.
[0049] Preferably, as another embodiment of the present invention, rollers are respectively provided on both sides of the other end of the flap. When the landing door of the elevator car is closed, the rollers abut against the inner side of the lower landing door of the elevator car. Two chutes corresponding to the two rollers are provided on the inner side of the lower landing door of the elevator car.
[0050] In this embodiment, rollers are provided on the flap. When one end of the flap contacts the inner side of the lower landing door, the flap is connected to the lower landing door through the rollers, avoiding damage to the flap caused by hard contact between the flap and the lower landing door. The rollers can be bearings. By providing chutes on the inner side of the lower landing door, when one end of the flap contacts the inner side of the lower landing door, the rollers are slidably arranged in the chutes, and the stability when the flap contacts the lower landing door is ensured through the limitation of the chutes on the rollers.
[0051] Preferably, as another embodiment of the present invention, the elastic member is a high-performance spring.
[0052] In this embodiment, the high-performance spring has excellent elastic properties, can withstand large deformations and loads, and will not easily lose its elasticity.
[0053] Preferably, as another embodiment of the present invention, the flap is made of a steel plate, and the flap is a hollow structure.
[0054] In this embodiment, the flap is made of a steel plate, which can ensure the strength of the flap. Since the density of the steel plate is relatively large, if the area of the flap is relatively large, its own weight will also be relatively large, which will cause too large a force on the lower landing door when the flap is placed on the lower landing door, and may affect the stability of the lower landing door. At this time, a plurality of hollow holes are provided on the flap, so that the flap is a hollow structure, and the own weight of the flap is reduced on the premise of ensuring the strength.
[0055] Preferably, as another embodiment of the present invention, as Figure 5 shown, both sides of the flap are connected to the inner wall of the elevator car through the elastic members.
[0056] In this embodiment, elastic members are provided on both sides of the flap and connected to the inner wall of the elevator car, so that the force on the flap during the rotation process is more uniform, and the stability of the connection between the flap and the inner wall of the elevator car can be better ensured.

It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the embodiments shown and described herein.
