Technical Field
The utility model belongs to construction elevator field especially relates to a construction elevator's automatically-controlled door drive arrangement.
Background
The construction elevator is generally used in building construction and is responsible for vertical transportation of people and goods. The elevator mainly adopts a cage to load people and goods, a cage door for people and goods to enter and exit is arranged on the cage, and the cage door has two switching modes of manual operation and automatic operation.
At present, the automatic cage door of a construction elevator is generally connected and driven in a steel wire rope or chain form, and a winch and a chain are flexibly connected, so that the following defects exist: the flexible connection can not fix the cage door, and the door lock is required to be arranged independently; the flexible connection transmission has the problems that a steel wire rope is separated from a groove or a chain is separated from a chain wheel and the like.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides an automatic door driving device of a construction elevator, which has simple structure and convenient installation, adopts rigid transmission, can freely stop and move, and does not need to be provided with a cage door lock independently.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a construction elevator's automatically-controlled door drive arrangement, includes actuating mechanism, gear, rack and drive plate, actuating mechanism is connected with the drive plate, and the drive plate is installed on the cage, and this actuating mechanism's output shaft and gear connection, the rack is installed on the cage door, and the gear's position cooperation is converted into the up-and-down motion of rack with actuating mechanism's rotary motion through gear and rack meshing.
In the technical scheme, the back wheel is mounted on the driving plate and is positioned behind the rack, so that the position of the rack is restrained, and the correct meshing between the gear and the rack is ensured.
In the technical scheme, the two side faces of the gear are provided with the limiting plates for preventing the dislocation of the rack and the gear.
In the technical scheme, the limiting plate is circular, and the diameter of the limiting plate is close to that of the gear.
In the technical scheme, the driving mechanism is a driving mechanism with a braking function, the cage door can be locked, and the door lock does not need to be arranged on the cage door independently.
The utility model has the advantages that: 1. the structure is simple, and the installation is convenient; 2. the rigid transmission is adopted, so that the operation and the stop can be freely carried out, and a cage door lock does not need to be independently arranged; 3. by adopting the structure of the back wheel and the clamping plate, the meshing relation of the gear and the rack can be effectively ensured.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 4, the automatic door driving device of a construction elevator comprises a driving mechanism 1, a gear 3, a rack 4 and a driving plate 2, wherein the driving mechanism 1 is connected with the driving plate 2, the driving plate 2 is installed on a suspension cage 7, an output shaft of the driving mechanism 1 is connected with the gear 3, the rack 4 is installed on a suspension cage door 8, the rack 4 is matched with the gear 3 in position, and the gear 3 and the rack 4 are meshed to convert the rotary motion of the driving mechanism 1 into the up-and-down motion of the rack 4. Thereby completing the brake switch of the cage door.
In the technical scheme, the back wheel 5 is mounted on the driving plate 2, and the back wheel 5 is positioned behind the rack 4 to restrain the position of the rack 4 and ensure the correct meshing of the gear 3 and the rack 4. The rack 4 is fixed between the gear 3 and the back wheel 5 through the back wheel 5, and the gear 3 and the rack 4 are guaranteed not to be separated in the tooth height direction in an engaged mode.
In the above technical scheme, both side surfaces of the gear 3 are provided with the limiting plates 6 for preventing the rack 4 and the gear 3 from being dislocated.
In the above technical solution, the limiting plate 6 is circular, and the diameter thereof is close to the diameter of the gear 3.
The limiting plate 6 has the same or close outer diameter with the gear 3, the thickness of the rack 4 is smaller than that of the gear 3, and when the gear 3 is meshed with the rack 4, the rack 4 is clamped between the two clamping plates 6, so that the rack 4 is ensured to be meshed with the gear 3 within the thickness range.
In the above technical solution, the driving mechanism 2 is a driving mechanism with a braking function, and can lock the door 8 of the suspension cage, and the door 8 of the suspension cage does not need to be configured with a door lock separately.
The driving plate 2 is installed on the suspension cage 7, the rack 4 is installed on the suspension cage door 9, and the rotation of the driving mechanism 1 is converted into the up-and-down linear motion of the suspension cage door 9 through the meshing transmission of the gear 3 and the rack 4, so that the brake switch of the suspension cage door is completed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
