Building safety detection circuit for winch

Abstract

The invention discloses a building safety detection circuit for a winch. The building safety detection circuit effectively solves the problem that the normal work of the winch and the safety of a building are affected due to the fact that blue smoke cannot be detected in time in the set detection mode of the winch. The safety detection circuit comprises a primary detection circuit and a secondary output circuit, and the primary detection circuit obtains reminding signals through abrasion signals of an air pipe of the winch and oil leakage signals, detected by an oil leakage sensor U1, between a valve guide pipe and a valve rod of the winch. The reminding signal is used for transmitting a temperature signal of an air cylinder of the winch and an abrasion signal, detected by the distance sensor U2, of a valve guide pipe of the winch to the secondary output circuit and outputting the reminding signal to the remote monitoring terminal; and the secondary output circuit is used for judging and calculating the temperature signal and the distance signal and then outputting an emergency signal to a remote monitoring terminal, so that the normal work of the winch is ensured.

Description

technical field [0001] The invention relates to the field of construction equipment detection, in particular to a construction safety detection circuit for a hoist. Background technique [0002] The characteristics of vertical lifting, horizontal or inclined pulling materials of winches make them applicable to the occasions where materials are lifted or pulled horizontally in buildings. Therefore, the inspection of winches has also become one of the key inspection contents of building safety inspection. . [0003] Therefore, sensors and manual inspection methods are set for the winch, wire rope wear sensors are set for the wire rope of the winch, speed sensors, temperature sensors, voltage sensors and other sensors are set for the motor, and ultrasonic sensors are set for the valve guide to detect the valve. Whether the conduit is worn or not, and transmit the signals detected by the sensor to the remote monitoring terminal, and the remote monitoring terminal will instruct ...
