Problems solved by technology
[0004] The purpose of the present invention is to propose a tower type blind shaft for the current tower type blind shaft hoisting system in order to solve the problem that the original hoisting equipment is too small due to shaft extension and the hoist needs to be replaced in order to increase the hoisting capacity, but it cannot be shut down for a long time Improvement method for non-stop production of lifting system

Embodiment Construction
[0017] A method for non-stop production transformation of a tower-type blind shaft hoisting system of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0018] Depend on figure 2 The schematic diagram of the modified tower blind shaft hoisting system shown and combined with figure 1 It can be seen that a kind of tower type blind shaft hoisting system non-stop transformation method of the present invention comprises the original tower type blind shaft hoisting system, and the former tower type blind shaft hoisting system is composed of blind shaft 1, former hoist chamber 2, Former hoist 2 ', former guide wheel chamber 4, former guide wheel 4 ' and lifting container 9 are combined to form. The original hoist 2' is installed in the original hoist chamber 2, the original guide wheel 4' is installed in the original guide wheel chamber 4, the lifting container 9 is located in the blind shaft 1, one end of the wire rope ...

The invention discloses a production-stop-free transformation method for a tower type interior shaft elevating system. The production-stop-free transformation method includes the steps of newly tunneling a new elevating system elevator chamber (5) at the position the L distance right above an original elevator chamber (2), excavating a new elevating system guiding wheel chamber (7) in the lower portion of the new elevating system elevator chamber (5), downwards drilling and digging a plurality of new elevating system steel wire rope holes (8) in a base plate rock pillar of the new elevating system guiding wheel chamber (7) through a jackdrill, enabling the new elevating system steel wire rope holes (8) to be communicated with a top plate of the original elevator chamber (2), finally, disassembling and moving an original elevator (2') and an original guiding wheel (4') at the overhauling or stopping maintenance time, and enabling a steel wire rope of a new elevating system elevator (5') to be connected with an elevating container (9) through the new elevating system steel wire rope holes (8). In this way, the elevating system is completely transformed, and the original elevator (2') is stopped using. According to the production-stop-free transformation method, under the condition that production of an interior shaft (1) is not stopped, the multi-rope-friction-wheel elevator of the interior shaft (1) normal in production is replaced, and the elevating system is accordingly upgraded and transformed.
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 tower-type blind shaft hoisting system, which can be used for non-stop transformation of tower-type blind shaft hoisting systems in underground mines such as iron and steel, non-ferrous metals, gold, chemicals, and coal. in the application. Background technique [0002] Blind shaft hoisting is widely used in underground mines in steel, non-ferrous metals, gold, chemical industry, coal and other industries, among which multi-rope friction wheel hoisting can be divided into tower type and floor type hoisting. [0003] In our country, there are many mines that adopt multi-rope friction wheel hoisting. Because the hoist originally selected is too small, the original hoist can no longer meet the safety requirements after the shaft is extended; in some mines, due to the small lifting capacity of the original design, With the develop...
