Problems solved by technology

[0002] There are two types of existing elevator door machines: frequency conversion door machine and permanent magnet synchronous door machine. The structure is relatively complicated. Due to the use of complex reduction devices, the transmission efficiency is low and the energy consumption is high.
The installation of the whole set of door operators is also inconvenient, the noise during operation is relatively large, and mechanical failures are prone to occur

Embodiment 1

[0029] Such as Figure 1 to Figure 10 As shown, an elevator door machine is installed on the crossbeam 101 of the car top frame 1 and includes a door machine device and a door knife driving device 13 .

[0030] Described door machine device comprises guide rail connection seat 2, fixed bracket 3, left door driving rack 4, guide rail fixing seat 5, door machine driving motor 6, driving gear 10, right door driving rack 7 and guiding device. Such as Figure 7 As shown, the guide rail fixing seat 5 is composed of a vertical plate 501 and a horizontal plate 502, the horizontal plate 502 is fixed on one side of the vertical plate 501, and the top and bottom edges of the vertical plate 501 have respectively Flanging to one side of the horizontal plate 502 to strengthen the structural strength of the vertical plate 501 . The middle part of the vertical board 501 has a through hole 503 , and the middle part of the horizontal board 502 has a notch 504 connected with the through hole 5...

Embodiment 2

[0059] Compared with Embodiment 1, in this embodiment, the axis of the drive gear is set along the vertical direction, the left door drive rack and the right door drive rack are both parallel to the beam of the car top frame, and the left The door driving rack and the right door driving rack are respectively located on opposite sides of the outer circle of the driving gear, and both are meshed with the driving gear. The position of the door machine drive motor is adjusted relative to the position of the drive gear, as long as the rotation of the drive gear can be driven, such as setting the axis of the output shaft of the door machine drive motor along the vertical direction, or keeping the door machine drive The output shaft of the motor is horizontal, and is connected with the driving gear through a coupling to realize the driving of the driving gear. In this embodiment, the structure having a relative connection relationship with the above structure can be adjusted adaptive...

Abstract

The invention relates to an elevator door machine. The elevator door machine is mounted on a cross beam of a car top frame and comprises a door machine device. The door machine device comprises a door machine drive motor, a drive gear, a left door drive rack, a right door drive rack and a guide device. The door machine drive motor is fixed relative to the car top frame. The left door drive rack and the right door drive rack are located on the two opposite sides of the outer circle of the drive gear correspondingly and both engaged with the drive gear. The drive gear is driven by the door machine drive motor to rotate relative to the car top frame. The left door drive rack and the right door drive rack can do opposite-direction linear motion in the direction parallel to the cross beam at the same time by means of rotation of the drive gear. The guide device is fixed relative to the car top frame and guides the linear motion of the left door drive rack and the right door drive rack. The left door drive rack is provided with a mounting structure used for being connected with a left car door, and the right door drive rack is provided with a mounting structure used for being connected with a right car door. The elevator door machine is simple in structure, convenient to mount, stable in running and low in noise, and energy saving and environment friendliness are achieved.

Description

technical field [0001] The invention relates to an elevator door machine, which belongs to the technical field of elevators. Background technique [0002] Existing elevator door operators include frequency conversion door operators and permanent magnet synchronous door operators. Their structures are relatively complex. Due to the use of complex reduction devices, their transmission efficiency is low and energy consumption is high. The installation of the whole set of door operators is also inconvenient, the noise during work is relatively large, and mechanical failures are prone to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator door operator with simple structure, convenient installation, energy saving and environmental protection. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an elevator door machine installed on the ...
