Test method for elevator main engine braking system

The invention relates to the technical field of an elevator control system, in particular to a test method of an elevator main engine braking system.

With the evolution of the times, the technology of architecture has also progressed with the development of industry and technology. As a result, human architecture has repeatedly challenged and broke through the scale and height of the inherent civilization buildings, and also Layer by layer, the skyline of the city is raised; among them, as the height of the building grows rapidly, the elevator equipment for vertical transportation is generated. Since then, the relationship between human civilization and buildings has been Significant and substantial development, and elevator equipment plays a pivotal role in modern architecture.

Please refer to the first figure, which is a schematic diagram of the operation of modern elevator equipment; as shown in the figure, the modern common elevator equipment E mainly includes: an elevator main engine E1, a power supply module E2, an elevator car E3, a pair The heavy module E4, a safety buffer module E5 and a corresponding pulley E6. The power supply module E2 can provide power to the elevator main engine E1 and generate a torque, and the elevator car E3 and the counterweight module E4 are vertically moved by the torque.

Further, the elevator car E3 and the counterweight module E4 are stopped and fixed at a specific height by the stop operation of the elevator host E1 and the operation of the brake device to complete the operation mode of the elevator device; For safety considerations, modern elevator equipment is often provided with the safety buffer module E5 at the bottom of the elevator shaft. In this way, the elevator car E3 can be provided with a buffering function through the safety buffer module E5 when an accident occurs, thereby avoiding the ride. The person/object inside it caused casualties/damage due to heavy fall.

Although the general elevator equipment has a buffer mechanism similar to the safety buffer module E5, it is obvious that when the floor area used by the elevator equipment is higher, the buffer mechanism can hardly load the elevator that is lowered by the higher floor. The car was frequently transmitted as a result of casualties.

The existing solution for improving the safety of the use of the elevator equipment is to install an emergency brake device on the elevator main engine E1. Thus, when the brake device of the elevator main engine E1 loses function or abnormality, the emergency brake can be used. The elevator main engine E1 that is lowered or rapidly pulled up is emergency-locked so that the elevator car E3 is fixed at a height to avoid the damage caused by the collision and is to be processed by the engineering personnel or the rescue personnel.

However, obviously, the above method is only a method of treating the standard and not treating the problem. In fact, since the emergency braking device achieves the effect of braking by directly locking the operation of the elevator main unit E1, it is conceivable that when the elevator device At the time of emergency stop, the person inside the elevator car E3 must be subjected to a very large downforce G force or even thrown up and cause injury.

Therefore, in order to achieve the above-mentioned main object of the present invention, the inventor of the present invention proposes a test method for an elevator main engine brake system, which is to confirm that the inverter of the elevator main engine is in a state where no elevator is used, and when there is no passenger in the elevator car, Perform the following steps: (1) causing a plurality of brake elements 121 of a brake module 12 to be simultaneously closed, and providing a plurality of braking forces such that an elevator car E3 is at a standstill; (2) transmitting a brake element 121 through a control unit 11 And measuring the braking force generated by the brake module 12 by a measuring unit 14 to still provide the elevator car E3 in a stationary state; if yes, proceeding to step (3); otherwise, proceeding to the step (6); (3) closing the braking element 121 opened in the step (2); (4) operating the control unit 11 to open the other braking element 121, and passing the measuring unit 14 to measure the braking Whether the braking force generated by the module 12 can still cause the elevator car E3 to be in a stationary state; if yes, proceed to step (5); if not, proceed to step (6); (5) repeat the operation (2) Go to step (4) and turn it on sequentially in this way. All of the braking elements 121 are separately measured by the measuring unit 14 for the braking force generated by the brake module 12; and (6) all of the braking elements 121 are closed.

In addition, in order to achieve the safety confirmation step before the elevator test operation to further improve the safety of use of the elevator equipment, the present invention further proposes the previous steps before the execution of the step (1): (P1) determining an elevator host Whether the inverter is in the state where no elevator is used; if yes, proceed to step (P2); if not, stop the test action; (P2) determine whether there is any passenger inside the elevator car E3; if yes, stop the test action; If not, step (P3) is performed; and (P3) is passed through the control unit 11 to cause at least one external display device to display an execution test message, and step (1) is performed.
