Abstract

The invention discloses a pulley rotating flexibility detection device and a method for detecting pulley rotating flexibility by using the pulley rotating flexibility detection device. The pulley rotating flexibility detection device comprises a base, transmission wheels, ropes, a tension detector and a power mechanism. The transmission wheels are movably connected with the base through a first rotating shaft. The ropes are sleeved on pulleys to be detected and the transmission wheels. The tension detector is fixedly connected with the ropes and is used for detecting tension values borne by the rope moving in the direction close to the pulleys to be detected and the rope moving in the direction far away from the pulleys to be detected. The power mechanism is connected with one of the transmission wheels or one of the pulleys to be detected and is used for driving the transmission wheels or the pulleys to be detected connected with the power mechanism to rotate and driving a pulley to be detected or the transmission wheels not connected with the power mechanism to rotate by aid of the rotating transmission wheels or the pulleys to be detected and the ropes. The pulley rotating flexibility detection device and the method for detecting pulley rotating flexibility by using the pulley rotating flexibility detection device solve the technical problems in the prior art that the pulley flexibility detection accuracy is low and pulleys with different flexibilities are difficult to be quantitatively distinguished.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a pulley rotation flexibility detection device and a method for detecting the pulley rotation flexibility by using the pulley rotation flexibility detection device. Background technique [0002] The pulley is a key part of the crawler crane for lifting and carrying items. The rotation flexibility of the pulley directly affects the weight of the items that the crawler crane can lift. [0003] Pulleys are usually figure 1 The pulley is used in the form of the shown pulley block. The rotational flexibility (or rotatability) of the pulley means that when the rope (usually a wire rope) wound on the pulley lifts the object, the pulley overcomes the rigid resistance of the rope wrapped around the pulley and The ability of the pulley block to resist. The poor rotation flexibility of the pulley will cause great wear between the pulley and the rope, resulting in low life of the pulley ...
