8. The overhead wire paying-off length measuring device as claimed in claim 7, wherein: the unidirectional wire inlet device comprises a wire frame of a U-shaped structure, adjusting springs are arranged on the upper side and the lower side of the left side of the wire frame, clamping sleeves of a semicircular structure are arranged below the adjusting springs, and a unidirectional wire inlet device is arranged on the right side of each clamping sleeve.
9. The overhead wire paying-off length measuring device as claimed in claim 8, wherein: the one-way inlet wire ware inside be provided with the toper cover, toper cover inside be provided with movable inlet wire pipe, activity inlet wire pipe left side periphery evenly be provided with the spacing steel ball of a plurality of.
10. Use of an overhead wire payoff length measuring device according to any one of claims 1 to 9, characterized in that: it comprises the following steps:
step 1: when the wire is paid off, the wire paid off from the pay-off rack enters the compensation wire feeding mechanism from the left side of the rack, a wire feeding device of the compensation wire feeding mechanism drives a wire feeding roller to rotate through a first motor, a first driving wheel, a first driving belt and a first driven wheel, the wire feeding roller drives the wire in a wire slot to move, the compensation device of the compensation wire feeding mechanism is convenient for automatically adjusting the distance of the wire feeding device according to wires of different specifications to automatically compensate, and the compensation wire feeding mechanism feeds the wire into a cleaning device to be cleaned;
step 2: the cleaning device drives the cleaning rollers on the upper side and the lower side inside the cleaning frame to rotate through the second motor, the second driving wheel, the second driving belt and the second driven wheel respectively, dust and dirt on the lead are brushed away through the cleaning rollers, the dust and the dirt on the lead are prevented from polluting the measuring device, and meanwhile, the phenomenon that the dust or the dirt is stuck on the measuring device to cause inaccurate measurement is avoided;
and step 3: the method comprises the following steps that a lead cleaned by a cleaning device enters a measuring device, the lead drives two meter counting wheels to rotate by virtue of friction force, an electronic meter counting device measures the number of turns of the meter counting wheels to calculate the length of the lead, the meter counting wheels drive a synchronous wheel to rotate through a synchronous belt, an encoder measures the number of turns of the synchronous wheel to calculate the length of the lead, relevant results are displayed on a display screen and compared, and if the relevant values are the same or the difference value is within an allowable range, the average value of the relevant values is taken as the actual length of the lead;
and 4, step 4: in the measuring device measurement process, fixed plate, swash plate, the restriction portion of buckling and restriction steel ball restrict the rotation direction of synchronizing wheel for the synchronizing wheel is unidirectional rotation, and one-way inlet wire device makes the wire folk prescription to passing through one-way inlet wire ware through toper cover, activity inlet wire pipe and spacing steel ball in addition, thereby avoids the phenomenon that the wire appears the backsliding, avoids measuring the error, improves measuring accuracy.
