Abstract
The utility model discloses a novel balance tail rope for a mine vertical shaft multi-rope frictional geared winch hoisting system. The balance tail rope comprises steel chain rings, wherein flame retardant and anti-static plastic wraps the steel chain rings; and the unit weight of the balance tail rope is equal to or greater than that of a hoisting main rope of the mine vertical shaft multi-rope frictional geared hoisting system. By adopting the novel balance tail rope for the vertical shaft multi-rope frictional geared winch hoisting system, defects of a steel wire rope balance tail rope can be effectively eliminated, and the novel balance tail rope has the characteristics of high corrosion resistance, small bending radius, high breaking strength, high safety, convenience in mounting, simplicity in maintenance, long service life, good economy and the like, and when the balance tail rope is popularized and used, the safety of the mine multi-rope frictional geared hoisting system can be obviously improved.
Description
Technical field
The utility model belongs to vertical shaft for mine frictional geared elevator system balance tail rope.
Background technology
In vertical shaft for mine frictional geared winch elevator system, the tail rope that is installed in cage, bob-weight bottom is the deadweight of the main rope end of balanced hoisting steel rope, reduce when promoting Tension Difference between the upthrow side and decline side steel rope, makes that cage is steady, the important device of safe operation.The balance tail rope of at present mine use is the steel rope balance tail rope, and its section form has two kinds of flat, circles, is connected to cage bottom and bob-weight bottom by flat-tail rope adaptor union and rounded tail rope rotary connector respectively.Through production and application practice for many years, the defective of steel rope balance tail rope also shows especially obviously.Because the particularity of mine down-hole production environment and working condition uses safety to make a big impact to the steel rope balance tail rope.Therefore and disrumpent feelings down-hole trickle, lum ponding, damp air, pernicious gas etc. can produce heavy corrosion to the steel rope tail rope, and corrosion causes that steel rope steel wire free area reduces, rupture strength reduces, and tail rope causes occuring the lifting accident.Secondly, circular cross section steel rope balance tail rope can can't be eliminated the twisting resistance of steel rope because rotary connector is stuck, cause twist with the fingers around rope strand and steel wire produce each other pine, from, open, loose situation, owing to the load skewness causes steel rope disrumpent feelings, cause the lifting accident during lifting.
The utility model content
The utility model provides a kind of New Mine vertical shaft frictional geared elevator system balance tail rope, solve existing steel rope balance tail rope because the corrosion and destruction that mine down-hole working environment and service conditions factor occur and the disrumpent feelings problem that causes because of fault of construction, improve the comfort feature of the safety of vertical shaft for mine frictional geared elevator system use and installation, maintenance.
For achieving the above object, the technical scheme taked of the utility model is; A kind of New Mine vertical shaft frictional geared elevator system balance tail rope, described balance tail rope comprises the steel chain ring, the periphery parcel plastics of this steel chain ring.
Described plastics adopt fire-retardant, anti-static plastic.
The unit weight of described balance tail rope is identical or heavy with the unit weight that described vertical shaft for mine frictional geared elevator system promotes main rope.
Adopt the utility model can effectively eliminate the defective of steel rope balance tail rope and have good corrosion resistance, the characteristics such as bending spring is little, rupture strength is high, safety is good and easy for installation, safeguard simply, long service life, good economy performance, promote the use of the safety that can significantly improve mine frictional geared elevator system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of New Mine vertical shaft frictional geared elevator system balance tail rope, described balance tail rope comprises steel chain ring 1, the periphery parcel plastics 2 of this steel chain ring 1.
Described plastics adopt fire-retardant, anti-static plastic.
The unit weight of described balance tail rope is identical or slightly heavy with the unit weight that described vertical shaft for mine frictional geared elevator system promotes main rope.
Using method of the present utility model: the utility model one end is connected to the cage bottom by the tail rope adaptor union, the other end is connected to Ping Heng Hammer bottom, when lifting winch by the Steel rope drive cage 5 that is connected with balance Hammer top with cage in vertical shaft during lifting, the balanced system that balance tail rope and bob-weight consist of plays the restrict effect of Tension Difference between upthrow side and the decline side steel rope of balance master in the cage lifting process, guarantee that the frictional geared winch elevator system is stablized, trouble free service.
