Increase the hoisting capacity problem in order to solve, common way is to open up a vertical shaft again, but investment is big, long in time limit, and the way that the mine that also has takes to change lifting means increases hoisting capacity, and not only equipment investment is big, and influences ordinary production.
Freely weigh down a jar problem for taking place, have no idea so far to solve.All there are every year a lot of accident of cage crashings to take place, cause tremendous loss to enterprise.
Publish China Construction Industry Press in August, 1988 " mining design handbook the 4th volume discloses a kind of three head sheave elevator system; Its concrete structure is between two lifting containers, to add steel cable again to link to each other; This root steel rope directly strides across the 3rd head sheave without gig and connects mutually; Purpose is in order to balance the deadweight of lifting container mutually, makes the lifting container deadweight not get into gig, and this three head sheaves promote because the difference of steel rope creep elongation amount; Tension force between three steel ropes is difficult for regulating suitably, is difficult to the effect that reaches desirable.
Summary of the invention the objective of the invention is to avoid the weak point of prior art; The two moving gig that provides a kind of mine to use; Its feature be to promote parameter more rationally, load-carrying and deadweight separately promote in the lifting container, and two cover brake system are arranged, and can avoid accident of cage crashing to take place.
A kind of two moving gig, it comprises two cover elevator system, and a cover is powered lift system, and it only bears lifting container load-carrying part, and a cover is two dynamic friction wheel unpowered systems, this cover system is mainly born the balance of lifting container deadweight;
