Embodiment Construction

[0016] Refer to the following figure 1 The configuration and rough operation of an embodiment of the present invention will be described. As shown in the figure, the elevator car 5 is provided with an elevator car room 1 for passengers to take, a load sensor 2 for counting the number of passengers, a position detector 3 for detecting that the elevator car reaches an absolute position, and When carrying out the characteristic test test, inform the passenger to leave the display 4 etc. of the elevator car. The elevator car 5 and the counterweight 6 are connected by the main rope 7, and are suspended on the sheave 8 and the deflection pulley 9 that transmit the driving force to the moving body. The rotational driving force of the driving device constituted by the electric motor 10 and the brake 11 for braking is transmitted to the sheave 8 .

[0017] This brake 11 generates a braking force, which is used as a stop holding force to prevent the elevator car 5 from moving due to t...

Abstract

The invention relates to an elevator system. A virtual buffer is arranged at the non-end floor in the lifting channel. The elevator is broken emergently from a predetermined position so as to collect the speed, position and time for passing through and other information of the elevator cage during the deceleration process. Besides, the elevator is collided with the virtual buffer so as to test and validate a series of deceleration data such as the detection of the deceleration starting position, the action of the brake and the adherence of the rope wheel and the suspension cable. The reliability of the brake system of the elevator which is arranged inside a department and an office building is very important, so the actual action and performance of the elevator are examined regularly and frequently in a mode of without damaging the device. The whole brake process of the elevator brake system, ending when the elevator cage is actually stopped, is regularly examined in a mode of without damaging the device.

Description

technical field [0001] The present invention relates to an elevator, in particular to an elevator system suitable for confirming the braking performance of the elevator. Background technique [0002] In the elevator system, in the rare situation where multiple faults occur at the same time, the possibility of collision between the moving body and the end of the hoistway cannot be ruled out. In order to take countermeasures in case of the above situation, a buffer is installed at the bottom of the hoistway to buffer the moving body so that it can be safely and slowly stopped. This kind of buffer is set at the bottom of the elevator passage, which is set according to the speed and load specifications of the elevator, so that when the moving body collides at a speed exceeding the specified value of the rated speed under the rated load, it can also decelerate at the required speed. to bear the moving body. In a very fast elevator, the total length of the buffer will become ver...
