Problems solved by technology

[0006] The above test method still uses an external test device. Before the test, it is necessary to debug the operation of the external device and the stability of the connection between the external device and the elevator system. The test requirements are high and the test time is long. It is not convenient for various types of elevators to perform uplink overspeed tests.

Embodiment 1

[0032] Embodiment one: if figure 1 As shown, it is only one of the embodiments of the present invention, a kind of elevator upward overspeed testing method, comprising the following steps:

[0033] S1: Run the elevator to the ground floor;

[0034] In order to enable the elevator to perform the upward test better, it is necessary to ensure that the elevator runs to the ground floor before the upward test can be performed, more space is reserved, and the test accuracy is higher.

[0035] Of course, for the sake of safety, the elevator runs to the ground floor. Before starting the upward overspeed test mode, it is necessary to confirm that the car is empty, the car door and hall door lock circuit are closed, the safety circuit is closed, and the leveling signal and door area signal are normal.

[0036] S2: Set the test parameters and enter the test mode;

[0037] Directly input command parameters in the elevator control system to enter the uplink overspeed test mode.

[0038]...

Embodiment 2

[0053] Embodiment two: still as figure 1As shown, it is only one of the embodiments of the present invention, an elevator upward overspeed test method, in order to facilitate the operator to test and the safety of the test, before starting the upward overspeed test mode, it is necessary to confirm the empty car. The lock circuit of the car, car door and hall door is closed, the safety circuit is closed, the leveling signal and the door area signal are normal, generally speaking, the operator first runs the elevator to the bottom floor, makes the car empty, and closes the car door After confirming that the safety circuit indicator light is on, the leveling signal light and the door area signal light are on, and the car door and hall door closed indicator lights are on, the uplink overspeed test mode can be started. Correspondingly, before step S6 is executed, that is, before exiting the uplink overspeed test mode, the safety loop needs to be disconnected.

[0054] Also, when s...

Abstract

The invention provides an elevator up-direction overspeed test method, and relates to the technical field of elevator safety. The elevator up-direction overspeed test method comprises the following steps that S1, an elevator is operated to a ground floor; S2, test parameters are set to enter a test mode; S3, an elevator band-type brake is loosened, so that the elevator begins to slide upwards; S4,the elevator operation direction and speed are recorded in real time; S5, whether a speed limiter acts or not is judged, if yes, the band-type brake tightly holds the elevator, and if not, the step S4 is continued to be carried out; and S6, the test mode exits. The elevator up-direction overspeed test method is simple and convenient, no extra devices, equipment and circuits are required, a test device is directly integrated to an elevator control system body, the test mode is carried out through the parameters, the test is convenient, the test limitation is small, and the elevator up-direction overspeed test method can be suitable for the up-direction overspeed test of various elevators.

Description

technical field [0001] The invention relates to the technical field of elevator safety, [0002] In particular, the present invention relates to an elevator upward overspeed testing method. Background technique [0003] Elevators are being more and more widely used in various buildings. The reliability and safety of elevators are closely related to the safety of passengers, so elevators need to be installed with a large number of safety detection and safety protection devices. These safety devices are often strictly inspected before leaving the factory, but there is a lack of corresponding testing after the elevator is fully assembled on site. Moreover, during the transportation and installation of the elevator, these safety devices may be damaged, but it is not easy to be discovered by the user. If a damaged safety device is used, it may cause safety problems and endanger the personal safety of the user. [0004] In particular, during the operation of the elevator, due ...
