The sintering machine of iron and steel enterprises is generally used in combination with a circular cooler, and the circular cooler is an important device for cooling sintered ores. As described in the name of the circular cooler, the equipment is annular (as shown in fig. 1) and consists of a plurality of trolleys, and the working principle is as follows: the discharged sinter cake is crushed and then continuously and uniformly dropped onto a trolley of a circular cooler through a funnel, the trolley runs at a constant speed by a friction wheel of a driving device, meanwhile, a blower sends cold air into an air box below the trolley, and the air box inputs the cold air into a hot sinter to exchange heat, so that the purpose of gradually cooling the sinter is achieved. According to the structure of the ring cooling machine, the stability of the operation of the trolley is realized mainly by the movement of the side wheels and the side rails, and the side rails are circular, so that the radius of the well-controlled side rails is an important guarantee for ensuring the normal operation of the ring cooling machine, and therefore, the radius of the side rails needs to be measured when the machine is stopped in detection so as to master the deviation condition of the radius of the rail, and the side rails are calibrated in time according to the deviation value.
The radius of the side rail refers to the horizontal distance from the center mark pile to the side rail, the height difference between the side rail and the center mark pile is about 9m, the common distance measuring method is a steel tape method or a distance measuring instrument method, but the center mark pile and the side rail are not visible, the structure of the side rail is complex, and a steel tape cannot pass through, so that the steel tape method is not suitable for measuring the horizontal distance from the center mark pile to the side rail. The distancer method needs to erect the distancer at center stake frame, erect prism reflector tripod in siding track department, need the people to stand and operate the prism base on the siding track, carry out the flattening centering, just can measure the gauge length, but the siding track is off-ground 1.2m, the prism tripod can't be stably erect on the siding track, and the personnel are difficult to stand and operate the prism base on the siding track, simultaneously because center stake and siding track are blind, exactly place the prism reflector in siding track department, the distancer also can't aim at the prism reflector, therefore the distancer method is also not applicable to the horizontal distance of measuring center stake to siding track.

In combination with the above three embodiments, the present application also provides a method for measuring a distance between blind side rails, which includes:
placing an auxiliary device 6 at a side rail 7, positioning a measurement observation prism 3 below the side rail 7, positioning the measurement observation prism 3 towards a center stake 9, contacting a fixing plate 1 of the auxiliary device 6 with the top surface of the side rail 7, attaching the top end of a fixing rod 2 of the auxiliary device 6 with the outer side surface of the side rail 7, observing a transverse horizontal bead 41 and a longitudinal horizontal bead 42 on the top surface of the fixing plate 1, adsorbing the whole auxiliary device 6 above the side rail 7 by a magnet at the bottom of an adjusting support 5, rotating a plurality of adjusting parts 52 to enable a fixing screw 51 to ascend or descend, enabling the transverse horizontal bead 41 and the longitudinal horizontal bead 42 to be in a horizontal state, enabling the fixing plate 1 to be in a horizontal plane at the moment, and enabling the measurement observation prism 3 to be in a vertical state with the ground at the moment;
the length of the fixed rod 2 is adjusted to adjust the height of the measurement observation prism 3, so that the measurement observation prism 3 and the distance measuring instrument 8 of the central stake 9 are in a see-through state, and the distance measuring instrument 8 aims at the measurement observation prism 3 to measure the distance;

the radius value of the side rail 7 where the auxiliary device 6 is placed is obtained by calculating the average of the three distance data.
It can be understood that three values are measured at the same side rail 7 measurement position, which is beneficial to further reducing measurement errors and improving measurement accuracy. The sliding distance of the sliding top plate 12 is smaller than the circumference of the side rail 7, so that the influence of the position change of the measurement observation prism 3 caused by the sliding of the sliding top plate 12 is smaller, which is equivalent to measuring again at the left and right adjacent positions of the original side rail 7 measurement position, calculating the radius value of the measurement position according to the three distance data, and effectively improving the measurement precision.
