Description

Technical Field

[0001] The present application relates to the field of retrofitting elevators, and in particular to an retrofitted elevator with an emergency rescue channel structure. Background Art

[0002] Balcony entry is one of the main ways to enter a house when an elevator is installed. When the elevator breaks down and stops, rescue workers need to enter the maintenance floor. However, for elevators that enter from the balcony, rescue workers often need to pass through the user's home when reaching the elevator location, which brings inconvenience to the rescue work.

[0003] A Chinese patent with authorization announcement number CN209635669U discloses an emergency rescue entrance and exit structure used for installing elevators in old houses. The emergency entrance and exit structure includes an entrance platform, which is used to connect the installed elevator and the old house. A ladder is provided between the upper and lower platforms. A movable rescue window is provided on the platform corresponding to the ladder. The movable rescue window includes a cover plate and a window opening mechanism. During rescue, rescuers can climb to different floors by using the ladder, without having to enter the home.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existence of ladders may cause some children to climb up, causing safety hazards. Summary of the invention

[0005] In order to reduce the potential safety hazards caused by climbing ladders, the present application provides an installed elevator with an emergency rescue channel structure.

[0006] The present application provides an elevator with an emergency rescue channel structure, which adopts the following technical solutions:

[0007] An elevator with an emergency rescue channel structure includes a shaft, a car is installed in the shaft, a door opener is provided on the car, a climbing structure for achieving height crawling is installed on the inner wall of the shaft beside the car, and the climbing structure is adjacent to the door opener; an entrance and exit for entering the climbing structure is opened on the side wall of the shaft on the same side as the door opener, and a safety door for opening and closing the entrance and exit is provided on the side wall of the shaft.

[0008] By adopting the above technical solution, when rescue is needed, 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 structure is arranged in the shaft, it can prevent children from climbing for fun and causing safety hazards, and it does not occupy the space in the corridor, and will not affect the travel of users; in addition, once a fire occurs in a high-rise building, the climbing structure in the shaft can be used as a fire rescue passage, and there is no need to take the emergency stairs, avoiding conflicts with the escaping residents and affecting the rescue efficiency. At the same time, for the installation of elevators entering the balcony, through the above solution, firefighters do not need to pass through the residents' homes, break windows, or damage anti-theft nets, thus saving rescue time and improving rescue efficiency.

[0009] By adopting the above technical solution, the climbing structure includes multiple ladders, and the inner wall of the shaft is equipped with multiple platforms arranged in the vertical direction. An independent space corresponding to the floor space is formed between two adjacent platforms. One ladder is installed in each independent space, and a window for passing between two adjacent independent spaces is also provided on the platform.

[0010] Preferably, during rescue, the operator enters the platform and then climbs to the floor that needs rescue by climbing a ladder. The platform ensures the safety of the rescuers to a certain extent.

[0011] Preferably, one end of the platform extends to the inner wall of the shaft at the position of the safety door, the platform is hinged on the inner wall of the shaft, the lower end of the ladder is hinged on the platform, a connecting rod is hinged on the ladder, the other end of the connecting rod is hinged on the inner wall of the shaft where the platform is located, and a driving component with a limiting function for driving the platform to rotate is provided on the inner wall of the shaft.

[0012] 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 shaft where the safety door is located, and this distance is a dangerous distance, so there will be certain safety hazards when the operator enters between the platforms. By extending the end of the platform close to the safety door to the position of the inner wall of the shaft, the hidden danger can be avoided. In order to allow the operator to enter the platform normally, the platform needs to have a certain width. In actual use, due to the existence of the door opener, when the car moves vertically, the platform with this width will interfere with the door opener, thereby causing the car to be unable to move normally. The platform is driven to rotate by the drive component until the platform is close to the inner wall of the shaft. At this time, due to the existence of the connecting rod, the ladder will follow the platform to rotate and fit on the inner wall of the shaft, thereby not affecting the movement of the car.

[0013] Preferably, the driving assembly includes a motor and a winding roller, the winding roller is rotatably connected to the inner wall of the shaft where the platform is located, a steel cable is wound around and fixedly connected to the winding roller, and the other end of the steel cable is fixedly connected to the ladder.

[0014] By adopting the above technical solution, when the platform is driven to rotate, the motor is turned on to drive the winding roller to rotate, so that the steel cable can be wound up. During the winding process of the steel cable, the ladder is driven to move, thereby driving the platform to rotate; the driving component realizes the platform rotation through electricity, saving manpower.

[0015] Preferably, a guardrail is provided in the shaft between the ladder and the side wall where the safety door is located, and the guardrail is fixedly connected to the ladder or movably connected to the inner wall of the shaft where the safety door is located.

[0016] By adopting the above technical solution, the setting of the guardrail can play a certain protective role when the operator enters the platform; due to the existence of the door opener, the guardrail will also affect the movement of the car, and the ladder is fixedly connected to the ladder. First, the platform can be driven to rotate through the driving component, thereby driving the ladder to move, and the movement of the ladder drives the movement of the guardrail, thereby avoiding the existence of the guardrail interfering with the movement of the car. Secondly, the guardrail can be slid in the direction away from the ladder until the guardrail no longer interferes with the door opener.

[0017] Preferably, the guardrail is slidably connected to the inner wall of the shaft along the width direction of the ladder, a screw rod is rotatably connected to the shaft, the screw rod is arranged along the sliding direction of the guardrail, and the screw rod and the guardrail are threadedly connected.

[0018] By adopting the above technical solution, when the guardrail needs to be used, the screw rod is rotated, and the screw rod and the guardrail are threadedly connected, and the guardrail is slidably connected to the wellbore, so that the rotation of the screw rod can drive the guardrail to move. The screw rod has a certain limiting function, which can limit the guardrail to a certain position to a certain extent.

[0019] Preferably, the safety door is rotationally connected to the side wall of the shaft via a vertically arranged rotating shaft, and the rotating shaft and the screw rod are transmission connected via a gear mechanism.

[0020] By adopting the above technical solution, during rescue, the operator opens the safety door, and the rotation of the safety door drives the rotating shaft to rotate, and the gear mechanism drives the screw rod to rotate. By opening the safety door, the guardrail is driven to move, thereby realizing the synchronous movement of the guardrail and reducing the number of operating steps.

[0021] Preferably, the platform is fixedly connected to the inner wall of the shaft, and the distance between one end of the platform close to the safety door and the inner wall of the shaft is for a door opener to pass through. A strap is hinged on the shaft for filling the distance, and the strap rotates to abut against the upper surface of the platform or the inner surface of the safety door. A driving component 2 is provided on the shaft for driving the strap to rotate.

[0022] By adopting the above technical solution, the step board is rotated to abut against the upper surface of the platform, which can facilitate the operator to enter the platform safely. At the same time, the step board can be attached to the inner surface of the safety door to facilitate the storage of the step board to prevent the existence of the step board from affecting the movement of the car.

[0023] Preferably, the strap is rotationally connected to the shaft via a horizontally arranged second rotating shaft, the second driving assembly is a second gear mechanism, and the second rotating shaft is transmission-connected to the first rotating shaft via the second gear mechanism.

[0024] By adopting the above technical solution, during rescue, the operator opens the safety door, and the safety door drives the rotating shaft 1 to rotate during the rotation process. The rotation of the rotating shaft 1 drives the rotating shaft 2 to rotate through the gear mechanism 2, and the rotation of the rotating shaft 2 drives the scaffolding to rotate. The driving member 2 drives the scaffolding to rotate by opening the safety door, thereby realizing the synchronous movement of the scaffolding and reducing the number of operating steps.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. This application can prevent children from climbing up and causing safety hazards by setting the ladder in the shaft. At the same time, the ladder is set in the shaft and does not occupy the corridor, which will not affect the user's travel;

[0027] 2. This application opens the safety door to drive the butt board to rotate and the guardrail to slide. When rescue is needed, the operator opens the safety door to drive the butt board to rotate until the butt board abuts against the platform. At the same time, the guardrail slides to the ladder position, making it convenient for the operator to enter the platform safely. BRIEF DESCRIPTION OF THE DRAWINGS

During the rotation of the safety door 25, the bevel gear 2 31 is driven to rotate. The bevel gear 2 31 rotates, which drives the bevel gear 1 30 to rotate, thereby driving the screw rod 29 to rotate. The rotation of the screw rod 29 drives the guardrail 13 to slide until the guardrail 13 is close to the ladder 12. At the same time, the safety door 25 rotates, driving the bevel gear 4 35 to rotate. The bevel gear 4 35 rotates, driving the bevel gear 3 34 to rotate. The rotation of the bevel gear 3 34 drives the rotating shaft 2 32 to rotate. The rotation of the rotating shaft 2 32 drives the slat 33 to rotate until the slat 33 abuts against the upper surface of the platform 9. Then the operator enters the platform 9, climbs to the designated floor through the ladder 12, and then enters the floor through the safety door 25, and then carries out the rescue work. After the rescue is completed, the safety door 25 is closed, thereby driving the slat 33 and the guardrail 13 to reset.
