Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a hatch structure mainly used in home elevators. Background Art

[0002] As people's requirements for quality of life increase, more and more families are installing home elevators. There are home elevators on the market that can vertically cross floors. The middle floors usually need to open a passageway to enable the car to move up and down. In order to make the elevator on the ground floor and use all the space upstairs when it is not working, a hatch assembly is usually set at the passageway of the floor. However, during the upward movement of the car, if there is a person or object on the hatch assembly at this time, the car hitting the hatch assembly will bring danger, thus posing a safety hazard. In addition, since the car will hit the hatch assembly at a certain speed, if it is a direct rigid collision, obvious noise will occur during the collision. Although some people have set up some buffering and shock-absorbing mechanisms to reduce the noise caused by the collision, the current use of buffering and shock-absorbing mechanisms is relatively complicated and the installation operation is relatively cumbersome. Utility Model Content

[0003] The utility model aims at the shortcomings of the prior art and provides an elevator hatch protection structure which has a simple structure, a more reasonable design, can eliminate potential safety hazards and can reduce impact noise.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: an elevator hatch protection structure, including a hatch assembly for covering the elevator passage opening on the floor, and a buffering and shock-absorbing mechanism is arranged on the bottom surface of the hatch assembly, characterized in that: a gravity sensing assembly is installed at the edge of the passage opening, and the hatch assembly is pressed on the gravity sensing assembly; a gravity sensing module is installed on the top of the car, and the hatch assembly is lifted up during the rising process of the car so that the hatch assembly is directly pressed on the gravity sensing module; the gravity sensing assembly and the gravity sensing module are respectively connected to the control system of the elevator.

[0005] Furthermore, the gravity sensing component is arranged on the side wall of the passage opening, and the side of the hatch assembly has a supporting edge extending outward. The hatch assembly is pressed on the gravity sensing component through its supporting edge pillow to cover the passage opening, and the surface of the hatch assembly is flush with the surface of the floor.

[0006] Furthermore, the buffer shock absorbing mechanism is a plurality of spring shock absorbers, and shock absorbing holes are respectively arranged on the gravity sensing module corresponding to the positions of the spring shock absorbers. When the car rises, the spring shock absorbers are first inserted into the shock absorbing holes to form a buffer shock absorbing structure.

[0007] Furthermore, gravity sensing components are installed on two opposite side walls of the passage opening, and supporting edges are arranged on two opposite sides of the hatch assembly.

[0008] Furthermore, the gravity sensing components on both sides are respectively installed on the side walls on both sides of the passage opening through supporting mechanisms; the supporting mechanisms are made of metal profiles.

[0009] Furthermore, the hatch assembly includes a metal frame fixed to the bottom surface of the hatch plate, so that the entire hatch assembly has a higher structural strength; the supporting edges are formed by extending outwards from both sides of the hatch plate.

[0010] Furthermore, the buffering and shock absorbing mechanism is arranged at the intersection of the frame, and the impact resistance of this part is stronger.

[0011] Furthermore, a positioning column is provided at the intersection of the frame, the positioning column is located between the buffer and shock absorbing mechanisms, and the downward extension length of the positioning column is greater than the downward extension length of the buffer and shock absorbing mechanisms; a positioning hole is provided on the gravity sensing module at the position corresponding to the positioning column.

[0012] The utility model sets a gravity sensing component at the edge of the elevator passageway of the floor and sets a gravity sensing module on the top of the car. When there is a person or object on the hatch assembly, it will be sensed by the gravity sensing component or the gravity sensing module, and the system can control the car to stop working immediately to prevent the person / animal / object on the hatch assembly from being lifted up by the car, thereby playing a protective role. By setting a spring-compressed buffer shock-absorbing mechanism to collide with the shock-absorbing hole of the car, the hatch assembly can be slowly pressed on the top of the car, thereby reducing the impact noise, and this buffer shock-absorbing structure is relatively simple and easy to install.

DETAILED DESCRIPTION

[0019] In this embodiment, refer to Figure 1-Figure 5 The elevator hatch protection structure includes a hatch assembly 1 for covering the elevator passage opening of the floor 4. The elevator car 3 moves up and down through the passage opening, and a buffer shock-absorbing mechanism is arranged on the bottom surface of the hatch assembly 1; a gravity sensing assembly 5 is installed at the edge of the passage opening, and the hatch assembly 1 is pressed on the gravity sensing assembly 5; a gravity sensing module 2 is installed on the top of the car 3, and the hatch assembly 1 is lifted up during the ascent of the car 3 so that the hatch assembly 1 is directly pressed on the gravity sensing module 2; the gravity sensing assembly 5 and the gravity sensing module 2 are respectively connected to the elevator control system, and the control system controls the working process of the elevator car 3 according to the signals provided by the two. Of course, the above-mentioned gravity sensing assembly 5 and gravity sensing module 2 are both existing products, and their sensing process and communication control process with the control system are also existing technologies, which will not be described here.

[0020] The gravity sensing component 5 is arranged on the side wall of the passage opening, and the side of the hatch component 1 has a supporting edge 13 extending outward. The hatch component 1 is pressed on the gravity sensing component 5 through its supporting edge 13 to cover the passage opening, and the surface of the hatch component 1 is flush with the surface of the floor 4.

[0021] The buffer shock absorbing mechanism is a plurality of spring shock absorbers 15. Shock absorbing holes 22 are respectively arranged at positions corresponding to the spring shock absorbers 15 on the gravity sensing module 2. When the car 3 rises, the spring shock absorbers 15 are first inserted into the shock absorbing holes 22 to form a buffer shock absorbing structure.

[0022] Gravity sensing components 5 are installed on two opposite side walls of the passage opening, and supporting edges 13 are arranged on two opposite sides of the hatch assembly 1.

[0023] The gravity sensing components 5 on both sides are respectively installed on the side walls on both sides of the passage opening through the supporting mechanism 6; the supporting mechanism 6 is made of metal profiles, such as aluminum alloy profiles.

[0024] The hatch assembly 1 comprises a hatch plate 11 with a metal frame 12 fixed to the bottom surface thereof, and the frame 12 provides the entire hatch assembly 1 with a higher structural strength; the supporting edges 13 are formed by extending outwards from both sides of the hatch plate 11 .

[0025] Each spring shock absorber 15 is respectively arranged at the intersection of the frame 12, and this part has a stronger anti-impact ability.

[0026] Two positioning columns 14 are also provided at the intersection of the frame 12 , and the two positioning columns 14 are located between the spring shock absorbers 15 . The downwardly extending length of the positioning columns 14 is greater than the downwardly extending length of the spring shock absorbers 15 . Positioning holes 21 are provided on the gravity sensing module 2 at positions corresponding to the positioning columns 14 .

[0027] When the hatch assembly 1 covers the passageway (i.e., the car is located on the ground floor and is not in use), any position thereof is subjected to a vertical downward force F, which acts on the gravity sensing assembly 5 through the supporting edge 13 of the hatch assembly 1, so that the gravity sensing assembly 5 receives a corresponding downward force. When the force F exceeds a set value (e.g., >50N), the gravity sensing assembly 5 is triggered, and a signal is transmitted to the control system, which controls the car 3 to stop working, so as to protect people / animals / objects on the hatch assembly 1 from being lifted up by the car 3.

[0028] When the car 3 is in operation and has lifted up the hatch assembly 1, the hatch assembly 1 is in contact with the car 3. At this time, when the hatch assembly 1 is subjected to a downward force P, the force will be transmitted to the gravity sensing module 2 on the top of the car 3. When the force P exceeds the set value (for example, >50N), the gravity sensing module 2 will be triggered, and the signal will be transmitted to the control system, so that the car 3 stops working, so as to protect people / animals / objects that suddenly fall on the hatch assembly during the movement of the car.

[0029] When the car 3 moves upward, the positioning column 14 first contacts and cooperates with the positioning hole 21 to control the hatch assembly 1 in the correct position. Then the spring shock absorber 15 docks and collides with the shock absorbing hole 22, so that the hatch assembly 1 is slowly pressed on the top of the car 3 to reduce the impact noise.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
