Description

Technical Field

[0001] This utility model belongs to the field of elevator cars, and particularly relates to an elevator car leveling gap covering structure. Background Technology

[0002] The elevator car leveling gap refers to the horizontal gap between the elevator car sill and the floor sill after the elevator car has reached and stopped at a designated floor. This gap is intentionally designed to prevent the car from colliding with the floor sill during the slight horizontal swaying that occurs during the elevator's ascent and descent, and is typically 2-3 cm wide. However, in actual use, some passengers may drop small items such as keys, bank cards, or coins when entering or exiting the elevator car. These small items can enter the shaft through the gap and are difficult to retrieve. Therefore, it is necessary to install a covering structure over the leveling gap to prevent passengers from dropping small items that are difficult to retrieve. Utility Model Content

[0003] The purpose of this invention is to provide a structure for covering the gap between elevator car landings. This invention has the advantage of preventing passengers from dropping objects into the shaft.

[0004] The technical solution of this utility model is as follows: an elevator car leveling gap covering structure, including a box with a front opening, a movable plate inside the box, a plurality of parallel rotating plates on the rear side of the movable plate, one end of the rotating plate being hinged to the movable plate, the other end of the rotating plate being hinged to the box, a drive plate parallel to the rotating plate on the rear side of the movable plate, one end of the drive plate being hinged to the movable plate, and a drive shaft extending downward from the box at the other end of the drive plate, and a motor connected to the drive shaft at the bottom of the box.

[0005] In the aforementioned elevator car leveling gap covering structure, the movable plate includes a rigid plate and a flexible plate located in front of the rigid plate, and both the rotating plate and the driving plate are hinged to the rigid plate.

[0006] In the aforementioned elevator car leveling gap covering structure, the rear side of the flexible plate is provided with a fixing groove into which the rigid plate is inserted.

[0007] In the aforementioned elevator car leveling gap covering structure, the bottom surface of the flexible plate is provided with a through groove.

[0008] In the aforementioned elevator car leveling gap covering structure, the top surface of the flexible plate is aligned with the top surface of the inner cavity of the box.

[0009] In the aforementioned elevator car leveling gap covering structure, the flexible plate is made of rubber.

[0010] In the aforementioned elevator car leveling gap covering structure, the rear side of the movable plate is provided with a positioning block that is fixed to the box body, and the height of the positioning block is equal to the height of the inner cavity of the box body.

[0011] In the aforementioned elevator car leveling gap covering structure, an adjusting bolt is provided at one long end of the box body, and a nut is provided on the adjusting bolt.

[0012] In the aforementioned elevator car leveling gap covering structure, the motor is connected to the drive shaft via a gearbox.

[0013] Compared with existing technologies, this invention incorporates a movable plate within the housing. During car movement, the movable plate does not enter the leveling gap, thus not affecting the normal operation of the car. When the car stops, the movable plate extends out of the housing under the action of a drive plate connected to the motor, covering the leveling gap and preventing small items dropped by passengers from entering the hoistway, making them easier to retrieve. Therefore, this invention has the advantage of preventing passengers from dropping objects into the hoistway.

[0014] Furthermore, the movable panel consists of a rigid panel and a flexible panel. When covering the leveling gap, the rigid panel remains inside the housing, while only the flexible panel covers the gap. In the event of a motor failure or the movable panel failing to retract completely into the housing, the flexible panel will not cause a hard impact on the car's lifting and lowering, ensuring safety. The extension distance of the movable panel can be limited by adjusting bolts to accommodate leveling gaps of varying widths, making it widely applicable. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example: A structure for covering the gap between elevator car floors, such as... Figure 1As shown, the box 1 includes a front opening. The width of the box 1 is 8-10cm. The length of the box 1 should be about 10cm greater than the width of the car door. The width of the car door is usually less than half the width of the car. The box 1 is formed by bending and welding stainless steel plate.

[0022] The box body 1 is provided with a movable plate 2, the length of the movable plate 2 is parallel to the length of the box body 1, and a number of parallel rotating plates 3 are provided on the rear side of the movable plate 2. One end of the rotating plate 3 is hinged to the movable plate 2, and the other end of the rotating plate 3 is hinged to the bottom plate of the box body 1.

[0023] The rear side of the movable plate 2 is provided with a drive plate 4 parallel to the rotating plate 3. One end of the drive plate 4 is hinged to the movable plate 2, and the other end of the drive plate 4 is provided with a drive shaft 5 extending downward from the box body 1. The bottom of the box body 1 is provided with a motor 6, and the motor 6 is connected to the drive shaft 5 through a reduction gearbox 14.

[0024] The movable plate 2 includes a rigid plate 7 and a flexible plate 8 located in front of the rigid plate 7. The rotating plate 3 and the driving plate 4 are both hinged to the rigid plate 7. The rigid plate 7 can be made of steel, and the flexible plate 8 is made of rubber. A fixing groove 9 is provided on the rear side of the flexible plate 8, into which the rigid plate 7 partially inserts, and the flexible plate 8 is glued to the rigid plate 7. A through groove 10 is provided on the bottom surface of the flexible plate 8, which allows the flexible plate 8 to be easily bent in the height direction. The top surface of the flexible plate 8 is aligned with the top surface of the inner cavity of the box body 1.

[0025] The rear side of the movable plate 2 is provided with a positioning block 11 fixed to the box body 1. The height of the positioning block 11 is equal to the height of the inner cavity of the box body 1, which can support the top plate of the box body 1. The positioning block 11 determines the limit position of the movable plate 2 retracting into the box body 1. One long end of the box body 1 is provided with an adjusting bolt 12, and a nut 13 is provided on the adjusting bolt 12. The axial position of the adjusting bolt 12 determines the limit position of the movable plate 2 extending outward into the box body 1.

[0026] Working principle: Box 1 is installed at the car sill or floor sill, with the top surface of Box 1 flush with the top surface of the corresponding sill, or Box 1 is entirely embedded below the corresponding sill, with the opening of Box 1 facing the leveling gap. Motor 6 is connected to the elevator control system.

[0027] During the elevator's ascent and descent phases, such as Figure 1As shown, the movable plate 2 remains entirely within the housing 1. After the elevator control system directs the car to the corresponding floor, before issuing the door opening command, it first starts the motor 6 to rotate forward. The motor 6 drives the drive shaft 5 to rotate through the reduction gearbox 14. The drive shaft 5 drives the movable plate 2 to rotate through the drive plate 4. The movable plate 2 moves outward as a whole until one end contacts the adjusting bolt 12. At this time, the rigid plate 7 remains inside the housing 1, while the flexible plate 8 extends out of the housing 1. The flexible plate 8 blocks the leveling gap, so that when a small object enters the leveling gap, it will not fall into the shaft, making it convenient for passengers to retrieve.

[0028] After the elevator control system shuts down and issues the door closing command, and before starting the traction machine, the starter motor 6 is first started in reverse. The moving plate 2 moves inward until it contacts the positioning block 11, and the whole is located inside the housing 1. In the event of a motor 6 failure, since the rigid plate 7 is entirely located inside the housing 1, only the flexible plate 8 remains on the outside of the housing 1. During the car's lifting and lowering process, the flexible plate 8 is easy to bend and does not affect the car's lifting and lowering.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
