The invention relates to a detection device and detection method for a composite traction steel belt of an elevator, wherein a high-frequency voltage source of the detection device for a composite traction steel belt of an elevator sends a high-frequency voltage of a preset frequency to each steel wire rope through a transmitting circuit module; The circuit module receives the output voltage of each steel wire rope based on the high-frequency voltage output, and sends the output voltage to the filter module; the power detection module receives the fundamental wave voltage output by the filter module after filtering the received output voltage, and based on the fundamental wave voltage Detect the power value of the composite traction steel belt, and send the power value to the judgment module; the judgment module compares the received power value with the initial value, and judges the wear degree of the composite traction steel belt based on the comparison result; when the steel belt When there is damage or a gap, the high-frequency voltage of each wire rope will diffract, and the power of the fundamental voltage obtained by filtering the signal received by the receiving end will decrease accordingly. Take safety protection measures before the failure of the composite traction steel belt occurs.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a detection device and a detection method for a composite traction steel belt for an elevator. Background technique [0002] The elevator composite traction steel belt is mainly composed of several steel wire rope cores arranged in parallel and coated with polymer materials. In actual work, the steel wire rope core bears most of the load on the steel belt. very important. The current method for detecting broken strands on the market is to connect all the steel wire ropes of the composite steel belt in series and apply a DC24V detection voltage to determine whether the strands are broken by making a break. The traditional technology is to add a relay on this basis to judge the breakage. [0003] In the process of implementation, the inventor found that there are at least the following problems in the traditional technology: the above method can only take corresponding safety pr...
