Description

Technical Field

[0001] The utility model relates to the field of floor doors, and in particular discloses a floor door structure automatically controlled by a construction hoist. Background Art

[0002] With the continuous development of the construction industry, the trend of mechanized replacement and automated reduction of manpower is becoming more and more obvious, which will comprehensively reduce the safety risks of on-site construction, reduce labor intensity, and improve construction efficiency and project quality. Under this trend, intelligent construction elevators that integrate intelligent elevator calling, one-touch access, safety monitoring, remote management, number recognition, upper and lower channel obstacle recognition, fault self-diagnosis and other functions, and do not require full-time drivers to operate, are becoming more and more popular. In the process of using intelligent construction elevators, how to make the floor door safe, simple, efficient and stable has become a problem that needs to be solved urgently.

[0003] At present, the commonly used intelligent construction elevator floor doors on the market are mainly divided into the following types: 1. Electric doors that are automatically controlled by electricity, such as electric rolling shutters. After the construction elevator reaches the designated floor, the control system of the floor door on that floor receives a signal and opens automatically. Its advantage is that it can be fully automated, but it has high requirements for electrical control, is expensive, and has a high failure rate; 2. Electromagnetic locks are installed on the floor doors. After the construction elevator reaches the designated floor, the control system of the floor door on that floor receives a signal, the electromagnetic lock opens, and the floor door can be opened normally. Its advantages are simple structure and low failure rate, but the door needs to be opened manually after the electromagnetic lock is opened, and it cannot be fully automated. In order to solve this technical problem, a floor door structure with automatic control of a construction elevator is proposed. Utility Model Content

[0005] Preferably, the front bumper plate and the rear bumper plate are fixed on the movable upper door structure.

[0006] Preferably, the connecting rod mechanism and the rotating sleeve are fixed to the outer frame of the landing door with bolts, and it is ensured that the connecting rod mechanism can rotate smoothly.

[0007] Preferably, the limit block is installed on the floor door flat sliding door, the floor door flat sliding door is fixed to the movable upper door structure through the door hinge shaft and the sliding shaft is embedded in the connecting rod sliding groove.

[0008] Preferably, the linkage bumper plate is fixed to the movable upper door structure by bolts.

[0009] Beneficial effects: The construction elevator's automatically controlled floor door structure is designed to not only achieve full automation through mechanical interlocking, but also has a low space occupancy rate. When the floor door is fully opened, the maximum height does not exceed 2400mm, which can meet the floor height requirements of most buildings and can be directly installed in the floor. At the same time, it adopts the previously commonly used flat-push floor door method, which is convenient for the modification of previous floor doors. It can effectively utilize resources to solve the problems of high cost and high failure rate of intelligent construction elevator floor doors, or the inability to achieve automation, which can reduce costs and simplify production processes; it can reduce the difficulty of installation and achieve floor door automation.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0028] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0029] See also Figure 1-15 A floor door structure automatically controlled by a construction elevator comprises a door hinge shaft 12, a limit block 14, a sliding shaft 15 and a movable upper door structure 7, wherein the door hinge shaft 12, the limit block 14 and the sliding shaft 15 are installed on the horizontal push floor door structure 13 to form a floor door horizontal push door 1, wherein the floor door horizontal push door 1 is installed on the floor door outer frame 2 through the door hinge shaft 12 and can be rotated inward to open; a front bumper plate 8, a linkage bumper plate 11 and a rear bumper plate 10 are installed on the movable upper door structure 7 to form a movable upper door 3; the movable upper door 3 is installed on the floor door outer frame 2 through a roller group 9 and can slide up and down; a connecting rod mechanism 4 is installed on the floor door outer frame 2 through a rotating sleeve 5, and is linked with the floor door horizontal push door 1 through a sliding shaft 15; a construction elevator electric door pick 6 is fixed on the construction elevator electric discharge door, can move up and down with the electric discharge door, and can also contact with the linkage bumper plate 11.

[0030] Wherein, the front bumper plate 8 and the rear bumper plate 10 are fixed on the movable upper door structure 7 .

[0031] The connecting rod mechanism 4 and the rotating sleeve 5 are fixed to the door outer frame 2 by bolts, and the connecting rod mechanism 4 is ensured to rotate smoothly.

[0032] The limit block 14 is installed on the landing door horizontal sliding door 1, and the landing door horizontal sliding door 1 is fixed to the movable upper door structure 7 through the door hinge shaft 12 and the sliding shaft 15 is embedded in the connecting rod sliding groove.

[0033] Wherein, the linkage collision plate 11 is fixed to the movable upper door structure 7 by bolts.

[0034] It should be noted that, first, when the electric discharge door is opened, the electric door pick 6 of the construction elevator is driven to open and move vertically upward. When it runs to a height of about 1650mm, it contacts the linkage bumper 11 and drives the movable upper door 3 to move upward as a whole. After the movable upper door 3 moves upward by about 50mm, the front bumper 8 touches the connecting rod mechanism 4, and the movable upper door 3 continues to move upward, driving the connecting rod mechanism 4 to rotate, and through the linkage of the connecting rod mechanism 4 and the sliding shaft 15, the floor door and the horizontal push door 1 are rotated inward to open, until the connecting rod mechanism 4 is separated from the inclined surface of the front bumper plate 8. At this time, the floor door and the horizontal push door 1 are fully opened, and the movable upper door 3 only serves to limit the rotation of the connecting rod mechanism 4 and no longer drives the connecting rod mechanism 4 to rotate;

[0035] The height of the linkage touch plate 11 of the movable upper door 3 is determined by the electric discharge door, and its upper limit is generally 1900mm. When it runs to 1800mm, the floor door horizontal sliding door 1 is fully opened; when the electric discharge door is closed, it drives the construction elevator electric door pick 6 and moves vertically downward. At this time, the movable upper door 3 slowly descends under the action of its own weight. When it descends to 1820, the rear touch plate 10 contacts with the floor door horizontal sliding door 1. As the movable upper door 3 continues to descend, the rear touch plate 10 drives the floor door horizontal sliding door 1 to rotate and close. When the movable upper door 3 drops to 1650mm, it contacts the door frame and stops descending. At this time, the vertical surface of the rear touch plate 10 is about 40mm lower than the floor door horizontal sliding door 1, that is, the limit block 14 is completely higher than the lowest edge of the vertical surface of the rear touch plate 10. The floor door horizontal sliding door 1 is completely locked under the action of the limit block 14 and the rear touch plate 10 and cannot be rotated to open;
