Detailed Description
In the following description, numerous technical details are set forth in order to provide a better understanding of the present application. However, it will be understood by those skilled in the art that the technical solutions claimed in the present application may be implemented without these technical details and with various changes and modifications based on the following embodiments.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
A first embodiment of the present application relates to a manual unlocking system for a vertically ascending and descending platform door, as shown in fig. 1, the manual unlocking system for a vertically ascending and descending platform door comprising:
The manual unlocking driving assembly is connected with the isolation lock assembly through a brake cable. The number of the manual unlocking driving assemblies is N, wherein N is an integer which is more than or equal to 1.
As shown in fig. 2, the manual unlocking driving assembly includes a box body 15, a box cover plate 6, a fixing block 13, a handle 5, a bearing cover 7, a gear shaft 8, a bearing 9, a gear 10, a rack 12, and a brake cable fixing seat 11.
The box body and the box body cover plate are combined and are used for packaging a gear shaft, a bearing, a gear, a fixing block and a rack. The cover plate of the box body is provided with a hole, and the handle penetrates into the box body through the hole and is fixed with the bearing cover, so that the bearing cover is driven to rotate. The bearing cover is mechanically connected with the gear shaft, optionally, the bearing cover and the bearing are integrally formed, and the gear shaft rotates along with the bearing cover and drives the gear to rotate.
The gear is meshed with the rack, and the movement range and direction of the gear and the rack are limited through the fixing block. The gear rotates to drive the racks to move oppositely or separate, wherein the moving direction of the racks is vertical to the axis of the gear. And the rack is mechanically connected with the brake cable fixing seat, and the brake cable fixing seat is connected with the brake cable, so that the movement of the rack drives the movement of the brake cable.
As shown in fig. 3, the isolation lock assembly includes: the lock body mounting box 22, the connecting bolt 20, the travel switch induction plate 21, the return spring 25, the travel switch 26, the brake cable fixing seat 11, the brake cable 3 and the brake cable guide wheel 24.
The lock body mounting box encapsulates a return spring, a brake wire guide wheel, a travel switch and a travel switch induction plate. The adjacent two sides of the lock body mounting box are respectively provided with a hole, so that the connecting bolt is inserted into the hole and the brake cable fixing seat is mechanically connected with one hole. The brake cable penetrates into the lock body mounting box through the brake cable fixing seat, is guided by the brake cable guide wheel, and is connected with one end, facing the lock body mounting box, of the connecting bolt. When the manual unlocking driving assembly is operated, the brake cable pulls the connecting bolt towards the inner side of the lock body mounting box. A travel switch sensing plate is attached to the connecting plug pin that touches a travel switch mounted in the lock body mounting box when the connecting plug pin is fully pulled into the lock body mounting box.
The reset spring is positioned between the tail end of the side of the lock body mounting box of the connecting bolt and the travel switch induction plate, and pushes the connecting bolt to the outer side of the lock body mounting box when the connecting bolt needs to be converted into a locking state.
When the isolation lock assembly is in an unlocking state, the connecting bolt retracts into the isolation lock assembly, and the connection between the door body connecting plate and the driving unit is disconnected, so that the isolation between the door body and the driving system is realized; when the isolation lock assembly is converted from the unlocking state to the locking state, the connecting bolt is pushed out of the isolation lock assembly by the return spring.
One side of the isolation lock assembly is provided with a door body driving connecting block (14), and the isolation lock assembly is connected with a driving system through the door body driving connecting block.
The isolation lock assembly is attached to the door body connecting plate (4) and is connected with the door body through the door body connecting plate.
In a preferred embodiment, as shown in fig. 4, when the number of the manual unlocking driving assemblies is more than 1, two communicated brake cables are arranged between every two adjacent isolation lock assemblies. Wherein the end 30a and the end 30b are both ends of the same rack, and the rack is connected with the rack in the other manual unlocking assembly through a brake cable between the ends 30b and 33 a; end 32a and end 32b are opposite ends of the same rack that is connected to the rack in the other manual unlocking assembly by a brake cable intermediate end 31a and end 32 a. When one of the handles unlocked manually rotates, the internal gear rotates, and the upper rack and the lower rack of the gear move oppositely. Because all manual unlocking mechanisms are connected in series, one gear rotates to drive all manual unlocking assemblies to rotate. Therefore, all the manual unlocking assemblies connected in series rotate as long as one handle rotates, and the locking pin of the isolation lock assembly is pulled by the manual unlocking assemblies, so that the unlocking function is realized.
The manual unlocking system of vertical lift platform door of this application can be applicable to platform shield door (closed), platform emergency exit (half high door), especially vertical lift's big degree of opening platform door.
The technical solution of the present application is further explained below:
1. the scheme comprises three parts, namely a middle manual unlocking assembly, a left isolation lock assembly and a right isolation lock assembly. The middle manual unlocking assembly is not limited to one, a plurality of middle manual unlocking assemblies can be arranged in series according to the opening degree of the door body, and one of the middle manual unlocking assemblies can be operated to keep synchronization so as to facilitate control.
2. An unlocking action flow: the middle manual unlocking handle rotates clockwise to drive the upper rack and the lower rack of the lock body to move towards the middle, and meanwhile, the brake cable is pulled. The brake cable passes through the brake cable fixing seat, and the brake cable guide wheel is connected with the connecting bolts of the isolation locks at the two ends. The gate line pulls the plug pin to pull out the plug pin, and the connection between the door body connecting plate and the driving unit is disconnected, so that the door body is isolated from the driving system. At the moment, the door body can be pushed away manually.
3. And (3) resetting the action flow: the middle manual unlocking handle rotates clockwise to drive the upper rack and the lower rack of the lock body to move towards the middle, meanwhile, the brake cable is pulled, the bolt is pulled out, then the door body is pulled to an initial position, the door body connecting plate at the position is aligned with the connecting hole of the driving system, the handle is released, the bolt is inserted into the connecting hole by virtue of the reset spring, and the door body connecting plate is restored to be connected with the driving system.
