Description
Technical Field
The utility model belongs to the technical field of the elevator, concretely relates to emergent rescue system of no computer lab elevator.
Background
When the elevator without the machine room has a fault, the power supply of the main machine needs to be disconnected in order to ensure safety, so that the main machine does not play a traction role any more, and at the moment, the brake of the main machine can hold the rotating wheel of the main machine tightly to perform braking operation; then, emergency rescue is carried out, the rescue workers need to observe the movement direction and speed of the lift car and whether the lift car is located in the unlocking area directly or through a display device, then the brake is released by starting a standby power supply, so that the brake releases a rotating wheel of the main machine, and at the moment, due to the fact that the weight of the lift car and the weight of the counterweight are not balanced, the lift starts to slide due to inertia; at the moment, a maintenance operator needs to observe the speed of the steel wire rope according to experience, and intermittently press and release the brake release button with certain frequency and times, so that the elevator slowly slides and stops to a flat-bed position.
However, there is in fact an extreme situation in which the car is far from the leveling position and the difference in gravity between the elevator car and the counterweight is too small, at which time the car cannot move by itself even if the brake is released; the most conventional rescue mode is that rescue workers need to enter a pit, a weight capable of breaking balance is added on the heavy side or the car side, then the rescue workers exit the pit, and then the brake is released to slide and stop, but the mode has higher risk and needs long time.
The chinese publication CN103523626A proposes a device, in which a liquid storage container is provided on the top or bottom of a car, and when a fault occurs, liquid is discharged, thereby breaking the weight balance; however, there are major drawbacks to using this approach: the liquid is directly poured into the shaft, and the parts in the elevator shaft are numerous, including a door machine, a safety switch, a limit switch, a buffer and even a motor, and are easy to be soaked by the liquid to cause damage, so that a greater potential safety hazard is caused; simultaneously, also need consume very big manpower and materials after the liquid is emptyd to carry out clearance, the test of well and pit, improved the running cost of elevator greatly.
