Abrasion detection device applied to sliding block of elevator door

The utility model discloses a wear detection device applied to a door sliding block of an elevator, which comprises the door sliding block and is characterized by further comprising a detection element which is embedded in a rubber material of the door sliding block and at least one part of which is embedded in a wear-resistant material of the door sliding block, and a detector connected with the detection element, at ordinary times, a loop of the detection element is conducted, an open circuit is formed after the detection element is abraded off, and the detector gives an alarm that the door sliding block needs to be replaced. By utilizing the device, the door sliding block can be replaced in an early warning manner when the detection element in the door sliding block is abraded and the detector detects that the loop of the detection element is disconnected, so that the technical problem that the door sliding block needs to be manually and regularly checked, judged and replaced in the elevator application is
