Problems solved by technology
[0004] The purpose of the present invention is to propose a multi-rope floor-to-ceiling tower modification for the current blind shaft hoisting system in order to solve the problem that the original hoisting equipment is too small due to the extension of the shaft and the hoist needs to be replaced in order to increase the hoisting capacity, but the production cannot be stopped for a long time.

Embodiment Construction
[0019] The non-stop production transformation method of a multi-rope floor-to-tower blind shaft hoisting system of the present invention will be further described in detail below with reference to the accompanying drawings.
[0020] by figure 1 The present invention is shown as a schematic diagram of the transformation scheme of a non-stop production transformation method of a multi-rope floor-to-tower blind shaft hoisting system and combination figure 2 , image 3 It can be seen that the non-stop production transformation method of the multi-rope floor-to-tower blind shaft hoisting system of the present invention includes the original multi-rope floor hoisting system and the original project. The original multi-rope floor hoisting system is a The original hoist chamber 14, the original hoisting system ropeway 3, the original guide wheel chamber 4, the original guide wheel 4', the blind shaft 1, the lifting container 13, the original hoist 2 is installed in the original hoist cha...

The invention discloses an interior shaft hoisting system on-line improvement method for changing the multi-rope floor type into the tower type. During normal production, a new hoisting system hoister chamber (5) is dug over the top of an interior shaft (1), a new hoisting system guide wheel chamber (7) is dug below the new hoisting system hoister chamber (5), then, a plurality of new hoisting system steel wire rope holes (8) are drilled downwards in a bottom plate rock pillar of the new hoisting system guide wheel chamber (7) so as to be communicated with the top end of the interior shaft (1), and finally, steel wire ropes are connected with a hoisting container through new system guide wheels, the new hoisting system steel wire rope holes (8) and the interior shaft (1) during the overhauling time or the stop time for a rest. In this way, renewal and improvement of the hoisting system are completed, and an original hoister is not used any more. Due to the fact that digging and installing of the new hoisting system are performed in a place different from a place of a system in use, influences between the two systems do not exist, and on-line improvement of the interior shaft hoisting system for changing the multi-rope floor type into the tower type can be achieved.
Description
Technical field [0001] The invention relates to a method for transforming a blind shaft hoisting system, in particular to a method for transforming a multi-rope floor-standing blind shaft hoisting system in which the hoisting equipment needs to be replaced but cannot be shut down for a long time. It can be used in steel, non-ferrous metals, gold, chemical, Flexible application in underground mines such as coal. Background technique [0002] Blind shaft hoisting is widely used in underground mines in steel, nonferrous metals, gold, chemical, coal and other industries. Among them, multi-rope friction wheel hoisting can be divided into tower hoisting and floor hoisting. [0003] In our country, there are many mines that use multi-rope friction wheels to lift. Because the original hoist selected is too small, after the shaft is extended, the original hoist can no longer meet the safety requirements; in some mines, due to the original design With the development of production, it is ne...
