An elevator with emergency rescue channel structure

technical field

The present application relates to the field of retrofitting elevators, in particular to a retrofitting elevator with an emergency rescue channel structure.

Background technique

Balcony entry is one of the main ways to install elevators. When the elevator fails and stops, rescuers need to enter the maintenance floor. For elevators with balcony entry, rescuers often need to go through the elevator when they reach the elevator. At the user's home, it will bring inconvenience to the rescue work.

The Chinese patent with the authorization announcement number CN209635669U discloses an emergency rescue entrance and exit structure applied to an old house with an elevator. The emergency entrance and exit structure includes a home entry platform. There is a ladder, and a movable rescue window is opened on the platform corresponding to the ladder. The movable rescue window includes a cover plate and a window opening mechanism; during rescue, the rescuer can climb to different floors through the ladder, so there is no need to enter the door. at home.

In view of the above-mentioned related technologies, the inventor believes that due to the existence of the climbing ladder, some children will climb, causing potential safety hazards.

SUMMARY OF THE INVENTION

In order to reduce the potential safety hazards caused by climbing ladders, the present application provides a retrofit elevator with an emergency rescue channel structure.

A kind of retrofitting elevator with emergency rescue channel structure provided by the application adopts the following technical solutions:

A retrofit elevator with an emergency rescue channel structure includes a hoistway, a car is installed in the hoistway, a door opener is arranged on the car, and an inner wall of the hoistway is installed on the side of the car for realizing height A climbing structure that crawls in a direction, the climbing mechanism is adjacent to the door opener; the hoistway is provided with an entrance and exit for entering the climbing mechanism on the side wall on the same side as the door opener, the hoistway The side wall is provided with a safety door for opening and closing the entrance and exit.

By adopting the above technical solution, when rescue is required, the operator opens the safety door and climbs to the designated floor through the ladder, and then enters the floor through the safety door, and then carries out rescue work; since the climbing mechanism is set in the well, it can prevent Children play and climb, causing potential safety hazards, and they do not occupy the position of the corridor, which will not affect the travel of users; in addition, once a fire occurs in the high-rise building, the climbing mechanism in the well can be used as a fire rescue channel, and there is no need to Take the emergency stairs to avoid up and down conflicts with the escaped residents, which will affect the rescue efficiency. At the same time, for the installation of elevators for the balcony entry, through the above scheme, firefighters do not need to pass through the residents' homes, and they do not need to break windows or damage the anti-theft net, saving rescue time. Improve rescue efficiency.

By adopting the above technical solution, the climbing mechanism includes a plurality of climbing ladders, a plurality of platforms arranged in the vertical direction are installed on the inner wall of the well, and an independent space corresponding to the floor space is formed between two adjacent platforms. One of the climbing ladders is installed in each independent space, and a window for passing between two adjacent independent spaces is also opened on the platform.

Preferably, during rescue, the operator enters the platform, and then climbs to the floor that needs to be rescued through a ladder, and the platform ensures the safety of the rescuer to a certain extent.

Preferably, one end of the platform extends to the position where the inner wall of the hoistway is at the position of the safety door, the platform is hinged on the inner wall of the hoistway, the lower end of the ladder is hinged on the platform, and the ladder is hinged with a connection The other end of the connecting rod is hinged on the inner wall of the hoistway where the platform is located, and the inner wall of the hoistway is provided with a driving component 1 with a limiting function for driving the platform to rotate.

By adopting the above technical solution, due to the existence of the door opener, in order to ensure that the door opener can move up and down with the car, there is a certain distance between the platform and the inner wall of the hoistway where the safety door is located, and this distance is a dangerous distance, so that the operator enters the platform. There will be a certain safety hazard in between. The end of the platform close to the safety door extends to the inner wall of the hoistway to avoid the occurrence of this hazard. In order for the operator to enter the platform normally, the platform needs to have a certain width. In the actual use process, due to the existence of the door opener, when the car moves vertically, the platform with this width will interfere with the door opener, so that the car cannot move normally, and the platform is driven by the driving component to rotate until the platform is tight. Leaning on the inner wall of the hoistway, at this time, due to the existence of the connecting rod, the climbing ladder will follow the rotation of the platform and fit on the inner wall of the hoistway, so that it will not affect the movement of the car.
