Problems solved by technology

The car door of the car is opened and closed by the door mechanism. As the frequency of elevator use continues to increase, elevator accidents increase accordingly. When an elevator fails, due to the particularity of the door mechanism, the elevator car door cannot Quickly opened by the rescuers, which increases the difficulty of rescue and reduces the efficiency of rescue

Embodiment 1

[0051] see Figure 1-10 , an elevator car with an emergency opening and closing mechanism, comprising a car floor 10, a transmission belt 11 is installed at the front end of the car floor 10, a pair of mounting plates 1 located at the rear side of the transmission belt 11 are fixedly connected to the front end of the car floor 10, and the mounting plate 1. The front end is fixedly equipped with a driving rod 2. The driving rod 2 is a prior art. Those skilled in the art can select a suitable type of driving rod 2 according to actual needs. For example, the model is: the driving rod 2 of LAP25. The upper end of the driving rod 2 is connected with a The pressing assembly 3 matching the transmission belt 11, the front end of the mounting plate 1 is connected with the cutting assembly 4 located at the lower side of the pressing assembly 3, and the left side of the cutting assembly 4 is connected with the linkage assembly 5 matching the driving rod 2; please refer to Figure 4 , the...

Embodiment 2

[0062] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 8 with Figure 9 , the upper end of the car floor 10 is fixedly installed with the main controller, and the front end of the installation plate 1 is fixedly installed with the sub-controller, the output end of the sub-controller is electrically connected with the driving rod 2 through the wire, and the input end of the sub-controller is connected with the main controller through the wire electrical connection. Through the mutual cooperation between the main controller and the sub-controllers, the driving rod 2 can effectively interact with the door mechanism of the elevator car, assist the use of the door mechanism, facilitate the maintenance o...

Embodiment 3

[0065] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to Figure 10 , a method for using an elevator car with an emergency opening and closing mechanism, comprising the steps of:

[0066] S1. When the elevator car fails and the door of the elevator car cannot be opened normally;

[0067] S2. The rescuer starts by controlling the driving rod 2, so that the pressing assembly 3 moves, acts on the transmission belt 11, and increases the tension of the transmission belt 11;

[0068] S3. Then the rescuer tries to control the normal opening of the elevator car door;

[0069] S4. If the elevator car door does not open normally, the control drive lever 2 continues to start, and drives the pressing component 3 and th...

Abstract

The invention discloses an elevator car with an emergency opening and closing mechanism, and belongs to the field of elevators. The elevator car with the emergency opening and closing mechanism comprises a car bottom plate; a transmission belt is mounted at the front end of the car bottom plate; a pair of mounting plates positioned on the rear side of the transmission belt are fixedly connected to the front end of the car bottom plate; a driving rod is fixedly mounted at the front ends of the mounting plates; and the upper end of the driving rod is connected with a pressing assembly matched with the transmission belt. The emergency opening and closing mechanism can be arranged on the car bottom plate to enable the pressing assembly and a cutting-off assembly to be matched with each other, and when the elevator car breaks down, the transmission belt of the elevator car door can be effectively damaged through the action of the pressing assembly and the cutting-off assembly, so that rescue personnel can open the elevator car through small external force to rescue trapped passengers, the rescue difficulty is effectively reduced, and the rescue efficiency is improved; and only a transmission belt in an elevator door motor mechanism is damaged, so that the economic loss during elevator rescue is effectively reduced, and the rescue cost is reduced.

Description

technical field [0001] The invention relates to the field of elevators, more specifically, to an elevator car with an emergency opening and closing mechanism. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. [0003] Modern elevators are mainly composed of traction machines (winches), guide rails, counterweight devices, safety devices (such as speed governors, safety gears and buffers, etc.), signal control systems, cars and hall doors. These par...
