Description

Technical Field

[0001] The utility model relates to the technical field of monitoring, in particular to a winch wire rope running distance monitoring device. Background Art

[0002] In inclined mines, winches are generally used to pull rail cars to transport minerals. The winch driver is relatively blind in judging the operating status of the winch. Whether the rail car will reach the designated location, whether the winch traction is overloaded, and the operating speed of the winch can only be estimated or listened to the instructions of the commanders underground or at the wellhead. When the signal device fails or the commander makes a slight mistake in the instructions, accidents will occur in the operation of the winch.

[0003] Prior art, such as the coal winch integrated monitoring device disclosed in announcement number CN103318793B, has a drum coaxial encoder that transmits pulse signals to PCL for calculation, which has developed into a method in which the movement of the wire rope drives the counting wheel of the counting device to rotate. However, it only performs a single measurement on the force measuring wheel, and because the wire rope structure is long, the monitoring device itself lacks effective limiting measures for the wire rope, and cannot ensure that the wire rope always remains in an orderly and smooth state during the process of being pulled and wound. It is very easy to cause looseness and displacement, which further leads to its concentrated distribution on the winding roller, which is not only unsightly, but also affects the subsequent packaging and use.
