Embodiment Construction

[0018] 1. First, according to the diameter of the permanent sky wheel, simmer the steel pipe into an arc of the same diameter, and take half of the arc as the main body of the temporary rope groove. The arc length of each section is determined according to the spoke distances of different sky wheel diameters.

[0019] 2. Weld a 6 mm thick steel plate at the lower part of the temporary rope groove, and drill holes according to the spoke spacing. The main function of the steel plate is to support the main body of the rope groove and serve as a fixed connection with the permanent sky wheel spokes.

[0020] 3. At the beginning of the rope change, first fix the temporary rope groove on the permanent sky wheel with U-shaped bolts. (Taking the four sky wheels as an example, a total of four circles with the same diameter as the sky wheel are adorned.)

[0021] 4. After the whole rope changing work is completed, remove the temporary rope groove and deliver it for formal lifting operat...

Abstract

Because hoist steel wire ropes have to be replaced in time according to a use rule in coal mine and non-coal mine floor model winch multirope vertical shaft hoisting. In the traditional technology of rope changing, as old steel wire ropes occupy permanent crown pulley grooves, new steel wire ropes can not be positioned for no groove, thus, the new steel wire ropes are damaged caused by the mutualextrusion and the roller compaction between the new ropes and the old ropes. The work of rope changing is very difficult. The invention provides a special grooving technology which is essentially applied to replacing steel wire ropes, after the new ropes and the old ropes are synchronously positioned, according to normal construction method, the new ropes and the old ropes are reversely adjusted so that the new steel wire ropes are put into the permanent crown pulley grooves and the old steel wire ropes are put into temporary grooves. Meanwhile, the old ropes can be orderly reclaimed by the temporary grooves. No matter how many ropes, such as 2, 4 or even 6, are replaced by the construction organization at once, the grooving technology is also applied to replacing hoisting ropes.

Description

[0001] 1. Fields of technical application [0002] The patent of the present invention relates to the hoisting of multi-rope vertical shafts with ground winches in coal mines and non-coal mines, because the hoisting wire ropes must be replaced in time according to the use regulations. The special rope groove technology of the present invention is mainly applied in the process of replacing the steel wire rope. Since the old steel wire rope occupies the permanent sky pulley rope groove, the new steel wire rope cannot be lowered due to the lack of a rope groove. 2. Background technology [0003] 1. According to the traditional construction method, the old and new steel wire ropes are lowered synchronously in the same rope groove of the permanent sky pulley at the same time. This method will easily cause the new rope and the old rope to squeeze and crush each other, causing the new steel wire rope to be injured. . [0004] 2. According to the traditional method, when starting to ...
