Description

Elevator car with emergency door on side wall

Technical Field

The utility model relates to an elevator safety technical field especially relates to an elevator car of lateral wall for emergency door.

Background

An elevator is a vertical elevator powered by an electric motor and equipped with a box-like car for carrying people or cargo in a multi-story building. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, the elevator can be divided into a low-speed elevator (less than 1 m/s), a high-speed elevator (1-2 m/s) and a high-speed elevator (more than 2 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased.

The elevator adopts a permanent magnet synchronous traction machine as power at the end of the 20 th century. The machine room occupation is greatly reduced, the energy consumption is low, the energy is saved, the efficiency is high, the lifting speed is high, and the like, and the development of real estate to the direction of an ultra-high layer is greatly promoted.

Along with the progress of science and technology, the rising height of a modern elevator is greatly increased, the load capacity of the elevator is greatly enhanced, and the safety coefficient of the elevator is also greatly increased. When the modern elevator has unexpected conditions such as stalling and the like, the safety device locks the elevator, so that the elevator is emergently stopped, and the elevator is prevented from dropping and serious casualties are prevented. In practical terms, when the elevator suddenly drops due to heavy load and is suddenly stopped by emergency protection, the position of the elevator suddenly stopped is unpredictable, and the elevator sometimes stops at the doorway of the corridor elevator and sometimes stops in the middle of the floor. Sometimes the elevator door can be opened and the elevator is located at a position which is just convenient for a victim to escape from the elevator after the elevator door is opened, but under the condition that the elevator door cannot be opened or the elevator emergency stop position is inconvenient for immediate rescue, the victim in the elevator cannot escape from the elevator in a short time, and the emergency stop protection device of the elevator can support the elevator car in a heavy emergency stop state for a long time, so that the safety protection performance of the elevator car is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a lateral wall is elevator car of emergency exit, thereby this device mainly breaks down scram to the elevator when the position that the rescue personnel of being not convenient for were rescued immediately, makes things convenient for personnel in the elevator to open the emergency exit to on escaping the cat ladder in the elevator well, with waiting for the rescue, thereby protection self life and property safety, with solving above-mentioned technical problem.

The utility model provides a technical scheme of above-mentioned problem is: the utility model provides an elevator car of lateral wall for emergency door, includes a car main part, the lateral wall of car main part is provided with emergency door system, emergency door system includes an emergency door main part to and corresponding being used for control the control system of emergency door main part operation, control system includes a servo motor to and be used for detecting the running state of elevator and the detection sensing device of position height, still including connecting the transmission of servo motor and emergency door main part.

Preferably, the emergency door body comprises a plurality of emergency door panels hinged to each other end to end in sequence.

Preferably, the emergency door further comprises a guide rail arranged at the upper and lower positions of the side wall of the car body to abut against the two ends of the emergency door panel and guide the operation of the emergency door body.

Preferably, still include a plurality of fixed enhancement fossil fragments that set up on each emergent door plant respectively, the both ends of enhancement fossil fragments are the same to be propped to in the guide rail.

Preferably, the transmission device comprises a rotating roller which is matched and connected with the servo motor, and a steel cable, one end of the steel cable is fixed on the rotating roller, and the other end of the steel cable is fixed at the position of the emergency door plate which is farthest away from the rotating roller.

Preferably, the emergency door further comprises an electronic lock arranged on the emergency door main body.

Preferably, the detection sensing device comprises a height sensor for detecting the position of the car body and a speed sensor for detecting the running speed of the car body.

Preferably, the electronic lock further comprises a sensing controller connected to the sensing device and connected to the electronic lock.

The utility model has the advantages that: the utility model relates to an elevator car of lateral wall for emergency door, this device improves on the basis of traditional elevator, be provided with an emergency door system through the lateral wall at car main part, this emergency door system is mainly used for after elevator stall is protected, a well department that personnel shift to outside the elevator in the elevator, thereby prevent that the elevator stall once more from causing major casualty accident, thereby the emergency door of this device is a plurality of articulated so that can fold mutually and make the lateral wall driven by the motor under emergency state, and finally open emergency door, form the passageway that personnel fleed in the elevator. The both ends of emergency door of this device are accomodate by the guide rail, therefore when emergency door opens or closes, the removal of emergency door board all can be orderly to can improve emergency door system's response speed. The emergency door of the device is controlled by the electronic lock when being opened, and when the elevator operates normally, the emergency door is locked by the electronic lock and cannot be opened easily, so that the danger that the emergency door is opened by mistake to cause people to fall from the emergency door is avoided. Only when the elevator stalls and is in the dangerous state of scram, the electronic lock can be controlled by the sensing controller fed back by the detection signal of the detection sensing device, so that the control on the emergency door is released, and the rescue workers can command the personnel in the elevator to orderly and safely escape from the elevator. The emergency door system is opened by winding the steel cable on the rotating roller under the control of the servo motor, so that the emergency door is opened, and the emergency door is more stable in opening mode than manual opening mode. And under the conventional running state of elevator, owing to install the enhancement fossil fragments on emergent door plant, consequently also need not worry that external force pastes and leads to emergent door plant to take place to warp under the condition to influence opening and closing of emergency door, this device has higher practicality and security performance.
