Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, specifically to a steel wire rope-driven folding and lifting device for a home elevator hall door. Background Technology
[0002] Due to the need to maximize the use of the shaft width, the width of the elevator shaft is basically the same as the width of the elevator. The double-door structure of the hall door has no room for movement in the horizontal direction, so it often adopts the house door-style outward opening method. Due to the existence of functional structures such as door frame, handle, and hinge structure design, it not only occupies external space when the door is opened, but also prevents the door width from being maximized. This often makes passengers feel that the door is too narrow and has a poor experience, especially causing inconvenience for passengers carrying items.
[0003] Currently, some companies use horizontal double-leaf folding doors, similar to warehouse elevator doors, to solve space problems. However, since both doors fold, they require corresponding power and transmission mechanisms, resulting in high costs and making them unsuitable for home use.
[0004] For the reasons mentioned above, it is necessary to further improve the opening method of the elevator hall door in order to maximize the opening of the hall door. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a steel wire rope-driven folding and lifting device for household stairwell doors that allows for longitudinal folding and opening, fully releasing space.

[0007] The motor is installed on the upper part of the elevator frame. The motor drives the drive shaft to rotate through a belt and pulleys. The drive shaft is horizontally arranged and extends to both ends of the elevator frame. The pulleys are fixed to both ends of the drive shaft.
[0008] The elevator frame has vertical tracks at both ends corresponding to the number of hall doors, and each hall door is installed in its respective track in a vertically sliding manner.
[0009] The pulley drives the raising and lowering of each hall door through a wire rope system, realizing the vertical folding opening and closing of the hall doors.

[0019] As the lower hall door is raised, the middle hall door and the upper hall door move upwards simultaneously, until the upper hall door, lower hall door, and middle hall door are at the same height, at which point the elevator hall door is fully opened.
[0020] Preferably, the door panel fixing frame is made of steel or iron.
[0021] Preferably, the door panel is made of a lightweight material.
[0022] Preferably, three sets of rope pulleys of different diameters are provided at both ends of the drive shaft.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0031] like Figure 1 As shown, a steel wire rope driven folding and lifting device for a residential elevator hall door includes an elevator frame 1 and a motor 2, a drive shaft 3, a pulley 4, a steel wire rope system, and at least two hall doors arranged based on the elevator frame 1.
[0032] In this embodiment, the hall door consists of three parts: the upper hall door 5, the middle hall door 6, and the lower hall door 7.
[0033] The motor 2 is installed on the upper part of the elevator frame 1. The motor 2 drives the transmission shaft 3 to rotate through the belt 21 and pulley 22. The transmission shaft 3 is horizontally arranged and extends to both ends of the elevator frame 1. The pulley 4 is fixed to both ends of the transmission shaft 3.
[0034] The elevator frame 1 has vertical slide rails 8 at both ends of its horizontal direction, corresponding to the number of hall doors. Each hall door is installed in its respective slide rail 8 in a vertically sliding manner.
[0035] The pulley 4 drives the raising and lowering of each hall door through a wire rope system, realizing the vertical folding opening and closing of the hall doors.
[0036] In terms of design, to optimize the hall door structure and facilitate transmission while achieving lightweight and easy decoration, the hall door is designed to include a door panel fixing frame 51 and a door panel 52. The door panel is installed in the door panel fixing frame, and the door panel fixing frame slides in conjunction with the slide rail. The steel wire rope system drives the door panel fixing frame. The door panel fixing frame is made of steel or iron, and the door panel is made of a lightweight material.
[0037] In terms of spatial design, when the three hall doors reach their highest point, the bottom of the doors extends beyond the upper edge of the elevator car, fully opening up the vertical space of the elevator car. The door panel width is greater than or equal to the width of the elevator car, maximizing the horizontal space of the elevator car and thus avoiding a feeling of stuffiness and confinement.
[0038] Example 1
[0039] like Figure 2 As shown, a stop block 9 for lifting the middle hall door 6 is provided on the rear side of the bottom end of the door panel fixing frame of the lower hall door 7, and a stop block 9 for lifting the upper hall door 5 is provided on the rear side of the bottom end of the door panel fixing frame of the middle hall door 6.
[0040] Each slide is equipped with a limiting block 10 to restrict the lowest position of the door panel fixing frame of each hall door.
[0041] The wire rope system includes a winding wire rope 11 with one end wound on a rope wheel 4 and the other end fixed to a door panel fixing frame of the lower hall door.
[0042] Working principle:
[0043] Motor 2 drives transmission shaft 3 to rotate via belt and pulley. Transmission shaft 3 drives rope wheel 4 to rotate. Rope wheel 4 winds up steel wire rope 11, thereby lifting the lower hall door 7. When the lower hall door 7 is lifted to the height of the middle hall door 6, the stop block 9 at its rear end lifts the middle hall door 6, achieving synchronous lifting. Continuing upward, the stop block 9 at the rear end of the middle hall door 6 lifts the upper hall door 5, achieving synchronous lifting, and finally achieving full opening of the hall doors.
[0044] When closing, as the lower hall door 7 moves downward, the middle hall door 6 and the upper hall door 5 move downward simultaneously. When the upper hall door 5 and the middle hall door 6 encounter the limit block 10 respectively, they stop moving downward, while the lower hall door 7 stops moving downward when it reaches the lowest point, thus closing the hall doors.
[0045] Example 2
[0046] like Figure 3As shown, the wire rope system includes a lifting wire rope 12, a first driven wire rope 13, and a second driven wire rope 14. Each slide is equipped with a limiting block 10 to limit the lowest position of the door panel fixing frame of each hall door.
[0047] The pulley 4 is connected to the door panel fixing frame of the lower hall door 7 via the lifting wire rope 12.
[0048] The bottom end of the central hall door 6 is provided with a first driven rope wheel 15. One end of the first driven steel wire rope 13 is fixed to the upper part of the door panel fixing frame of the lower hall door 7, and the other end is fixed to the top of the elevator frame after passing through the first driven rope wheel 13.
[0049] The bottom end of the upper hall door 6 is provided with a second driven rope wheel 16. One end of the second driven rope 14 is fixed to the middle of the door panel fixing frame of the middle hall door 6, and the other end is fixed to the top of the elevator frame after passing through the second driven rope wheel 16.
[0050] As the lower hall door is raised, the middle hall door and the upper hall door move upwards simultaneously, until the upper hall door, lower hall door, and middle hall door are at the same height, at which point the elevator hall door is fully opened.
[0051] Specifically, during the upward movement, as the lower hall door 7 is raised, the first driven steel wire rope 13 lifts the middle hall door through the first driven rope wheel 15; when it rises to a suitable height, the second driven steel wire rope 14 lifts the upper hall door through the second driven rope wheel 16, ultimately achieving the synchronous lifting of the three hall doors to the highest point.
[0052] It emphasizes the synchronization of the three compartment doors, and the opening efficiency and smoothness are relatively better than the scheme in Example 1.
[0053] In other embodiments, three sets of rope pulleys of different diameters are provided at both ends of the drive shaft. The three sets of rope pulleys lift the three hall doors through steel wire ropes, so that the three hall doors perform lifting and lowering actions synchronously but at different speeds, and overlap at the highest point and unfold at the lowest point.
[0054] This utility model uses a steel wire rope to drive a three-fold lifting device for home stairwell doors. It adopts a simple and practical design concept, with synchronous pulleys and synchronous belts for transmission. The rope pulley agitates the steel wire rope to drive the three doors to lift in sequence, maximizing the space after the doors are opened in an automatic opening manner, providing passengers with both space and convenience.
[0055] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
