Description
Technical Field
The invention relates to an elevator emergency rescue method, in particular to an energy-saving elevator emergency rescue method.
Background
In order to improve the safety performance of an elevator, an emergency power supply and a rescue device are generally arranged in an existing elevator system, so that when the elevator is in a power failure or fault condition, the rescue device can emergently switch the power supply and move the elevator to a nearest flat-bed position, and passengers trapped in the elevator can safely leave. The existing rescue device judges the stopping position according to the principle that the distance between the elevator car and the adjacent flat bed is detected through the positioning device, and the flat bed with the shortest distance is used as a stopping point. The purpose of the rescue mode is to change and reduce the energy consumption required by rescue by shortening the moving distance of the elevator; however, since the elevator has a weight difference between the counterweight and the load weight, the direction of heavy load of the elevator is either directed toward the elevator or toward the counterweight. Therefore, when the rescue device is used for carrying out emergency driving on the elevator, the elevator can be driven in the direction opposite to the heavy load direction, so that the moving distance required by the elevator is shortened, the energy consumption of the rescue process on an emergency power supply is increased, and the originally required energy consumption saving effect cannot be achieved.
In addition, for the elevator with the distance between the super-high buildings, when the elevator is close to the middle position of two flat floors, the influence of the difference of the moving distance of the elevator on the energy consumption of the elevator is small, and the influence of the heavy load direction of the elevator on the energy consumption of the elevator is large; if the flat bed with shorter moving distance is selected as the stopping point, the emergency power supply easily causes the problem of insufficient self-rescue distance of the elevator due to the increase of energy consumption, and the safety of the elevator is reduced.
Therefore, the existing elevator rescue device has the problems of poor energy-saving effect and low safety.
Disclosure of Invention
The invention aims to provide an energy-saving elevator emergency rescue method. The energy-saving device has the characteristics of good energy-saving effect and high safety.
The technical scheme of the invention is as follows: an energy-saving elevator emergency rescue method comprises the following steps:
firstly, starting a rescue device after the power of the elevator is cut off, and stopping the elevator;
closing the brake of the elevator to enable the elevator car to be in a free lifting state;
thirdly, the elevator and the counterweight device form relative movement due to weight difference, so that the elevator is stressed to rise or fall, and then the rescue device senses the lifting direction of the elevator;
stopping the elevator, and applying driving force to the elevator to enable the elevator to continuously move in the lifting direction in the step (II) and reach a leveling position;
cutting off power supply to the elevator and stopping the elevator.
In the energy-saving elevator emergency rescue method, the rescue device loosens the elevator brake, and the traction machine is in a natural movement state at the same time, so that the lift car is in a free lifting state.
In the energy-saving elevator emergency rescue method, the elevator releases a forward pulse or a reverse pulse to the tractor encoder after lifting, and then the rescue device judges the lifting direction of the elevator according to the pulse.
In the energy-saving elevator emergency rescue method, in the step (iv), the velometer is used for detecting the free lifting speed of the elevator, and when the moving speed of the elevator exceeds 0.1m/s, the band-type brake is tightly held to brake the elevator.
Compared with the prior art, the invention has the following characteristics:
(1) before the elevator is subjected to emergency rescue, the elevator is in a free lifting state and the lifting direction of the elevator is sensed, so that the rescue device can judge the heavy load direction of the elevator, and the elevator is driven to lift according to the heavy load direction of the elevator, so that the energy consumption required by the elevator in the moving process can be effectively reduced, the energy consumption is saved, the self-rescue distance of the elevator is increased, and the safety of the elevator rescue device is improved;
(2) the elevator is braked and dragged after the heavy-load direction of the elevator is sensed, so that the problem that the elevator cannot be braked in time due to too high lifting speed can be avoided, and the safety of the elevator is improved; on the other hand, the elevator can be ensured to move stably in the emergency rescue process, the safety and the comfort of the elevator are further improved, the riding experience of passengers is increased, and unnecessary panic is avoided;
therefore, the invention has the characteristics of good energy-saving effect and high safety.
Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention.
Examples are given. An energy-saving elevator emergency rescue method comprises the following steps:
firstly, starting a rescue device after the power failure of the elevator, and tightly holding the elevator and braking the elevator;
after the elevator stops moving, the rescue device releases the brake to release the brake of the elevator, and meanwhile, the traction machine stops rotating and is in a natural moving state, so that the lift car can be lifted freely under stress and drive the traction machine to rotate;
the elevator and the counterweight device form relative movement due to weight difference, namely move towards the heavier side, so that the elevator is stressed to rise or fall; the elevator drives the traction machine to rotate clockwise or anticlockwise after lifting, corresponding pulses are released to the encoder, namely, the traction machine releases forward pulses to the encoder when rotating clockwise, the traction machine releases reverse pulses to the encoder when rotating anticlockwise, and the rescue device judges the heavy load direction of the elevator through the obtained pulse signals;
fourthly, when the speed of the elevator measured by the velometer exceeds 0.1m/s, the rescue device tightly holds the band-type brake to stop the elevator, and then the traction machine rotates to apply driving force to the elevator, so that the elevator continuously moves in the heavy load direction and reaches the leveling position;
and fifthly, the rescue device cuts off the power supply to the elevator and shuts down the elevator.
The working principle of the invention is as follows: before the rescue device drives the elevator to ascend and descend, the heavy load direction of the elevator is detected and the traction machine is driven according to the direction, so that the elevator can move in the heavy load direction during rescue, the energy consumption of the emergency power supply during driving is effectively reduced, the energy-saving effect is realized, the self-rescue distance of the elevator is prolonged, and the possibility that the elevator cannot smoothly reach a flat floor due to insufficient electric energy is reduced.
