Embodiment Construction

[0019] Such as figure 1 Shown, a kind of monorail locomotive U-turn method on the spot, as follows:

[0020] The first step is to select the branch roadway intersection suitable for U-turn on the spot

[0021] In the main roadway 2 where the monorail locomotive 1 is bifurcated, select the bifurcated roadway 5 with a width B of not less than 3.8m, and the Niubi intersection point 6 at which the angle a at the bifurcation is not less than 40° as the place for turning around on the spot. Through on-site measurement, the construction drawing shall be made according to the size of the turning radius R not less than 4m. When drawing, it is required to calculate the safety clearance J between the monorail locomotive 1 and the intersection point 6 of the bull nose when the monorail locomotive 1 is turning according to the length and width of the monorail locomotive 1; The protruding part conforming to the safety gap J shall be excavated and re-supported;

[0022] The second step is ...

Abstract

The invention discloses an in-situ turn-back method for a monorail crane. The in-situ turn-back method comprises the steps that firstly, in a main roadway where the monorail crane operates in a branched mode, the ox-nose-like cross point with the roadway width not being lower than 3.8 m and the branched position included angle not being smaller than 40 degrees is selected as an in-situ turn-back site; then a special turn-back curve is machined and mounted; and finally, the special turn-back curve is utilized to conduct in-situ turning back in a branched roadway. Three persons implement operation through the overhauling time without a line special for crane turn-back, in-situ turning back of the monorail crane can be completed within 0.5 h, and influences on normal production of excavatingwork faces are completely avoided.

Description

technical field [0001] The invention relates to the coal mine underground transportation technology, in particular to the monorail crane transportation technology. Background technique [0002] At present, some underground production areas of coal mines use monorail locomotives as auxiliary transportation methods. A single monorail locomotive is more than 4 million yuan, and a normal production mining area is equipped with one set. Although the price is high, monorail locomotive transportation has the remarkable characteristics of simple system, small amount of mine construction, less equipment and personnel, fast operation speed, and high safety. It has become the main auxiliary transportation mode in coal mines. Since the location of the locomotive is adjusted according to the previous operation route of the service mining area when the equipment is installed, when the transportation route changes from the previous setting, in order to ensure that one locomotive can meet ...
