Description
Technical Field

Background
Currently, friction type mine hoisting systems generally comprise a hoisting container, a hoisting wire rope, a balance wire rope, a friction wheel, a guide wheel (or a head sheave), a motor and the like, wherein the working principle of multi-rope friction type hoisting is as follows: the flexible friction transmission principle is adopted, the hoisting steel wire rope surrounds the friction wheel, and the friction between the steel wire rope and the friction pad is utilized to transmit power. The lifting steel wire rope is put on the friction wheel, one lifting container is generally hung at two ends of the lifting steel wire rope respectively, or one lifting container is hung at one end, the balance weight is hung at the other end, the balance steel wire rope is hung at the bottom of the container or the balance weight, and the balance steel wire rope is used for balancing the weight of the lifting steel wire rope, so that the power of the motor is reduced. When the friction wheel works, the tensioned lifting steel wire rope is tightly pressed between the friction gaskets under a certain positive pressure to generate friction force, and under the action of the friction force, the lifting steel wire rope moves along with the friction wheel, so that the lifting or the lowering of the container is realized. However, because the environment in the shaft is poor, the environment is wet and water is sprayed, or corrosive water mist such as acid, alkali, salt and the like exists, the corrosion to the steel wire rope is large, and the defects of corrosion, deformation, diameter shrinkage and the like of the steel wire rope are often caused, so that the service life of the steel wire rope is shortened. At present, the common solution is to carry out galvanization and corrosion prevention on the surface of the steel wire rope, wherein the rigidity of the steel wire rope is increased after galvanization, the flexibility is reduced, the steel wire rope loses corrosion resistance again after the galvanized layer is worn in the use process, and the service life of the steel wire rope used in the mine is shortened due to serious corrosion loss, the steel wire rope is frequently replaced, and the cost is increased; and along with the increase of lifting height and the increase of lifting load, the diameter of the required steel wire rope is correspondingly increased, and the lifting steel wire rope in the deep well and ultra-deep well mine lifting system has the problems of large self weight, small bearing capacity and short service life.

According to still another embodiment of the present invention, the manner in which the positioning steel wire 30 is fixedly connected to the steel wire rope 20 or the high performance fiber ropes 20 is not particularly limited, and a person skilled in the art may choose according to actual needs, so long as the positioning steel wire 30 is required to be parallel or nearly parallel to the steel wire ropes 20 or the high performance fiber ropes 20 in the same plane, for example, as shown in fig. 4 or 5, the positioning steel wire 30 may be fixedly connected to each steel wire rope 20 or each high performance fiber rope 20 by a winding manner and/or through a rope clip 31, thereby further improving the uniformity of the distribution of the steel wire ropes 20 or the high performance fiber ropes 20 in the mine hoisting composite belt, thereby not only being beneficial to improving the cohesive force of the steel wire ropes or the high performance fiber ropes, but also enabling each steel wire rope or each high performance fiber rope to exert a sufficient lifting effect under the load condition, avoiding the phenomenon of stress concentration during the use, thereby significantly improving the firmness and stability of the mine hoisting composite belt, and being beneficial to improving the range of the mine hoisting composite belt. Further, the diameter of the positioning steel wires 30 can be 2-5 mm, and the distance L between two adjacent positioning steel wires 30 can be 50-100 m, so that the influence on the overall thickness and width of the mine hoisting composite belt is small, the parallel distribution of a plurality of steel wire ropes 20 or a plurality of high-performance fiber ropes 20 in the mine hoisting composite belt can be further facilitated, and the firmness, the stability, the load carrying range and the service life of the hoisting composite belt can be further facilitated to be improved. It should be noted that, the winding manner of the positioning steel wire and the type of the rope clip in the present invention are not particularly limited, and those skilled in the art may select according to actual needs, for example, the winding manner of the positioning steel wire may be simple winding, tying a knot for winding, matching with the rope clip for winding, etc., and the rope clip may be detachable or non-detachable, single-hole or double-hole, U-bolt type or double saddle shape or cohesion, etc.
According to another embodiment of the present invention, the lifting composite belt may be used alone or in a plurality of side-by-side manner, and the number of lifting composite belts may be selected by those skilled in the art according to the actual conditions of the lifting height of the lifting system, the weight of the lifting container, the diameter of the friction wheel, the load demand, etc., and the number and diameter of the steel wire ropes 20 or the high performance fiber ropes 20 in the lifting composite belt.
According to yet another embodiment of the present invention, as shown in fig. 4, the cross section of the mine hoisting composite belt may have a trapezoid shape, and the bottom angle θ of the trapezoid shape may be 30 to 70 degrees. When the friction wheel is provided with the guide groove, the surface of the trapezoid upper bottom is close to the guide groove, and the surface of the lower bottom is far away from the guide groove, so that the movement direction of the lifting composite belt can be adjusted, the phenomena of collision, overlapping and the like when the mine lifting composite belt is deviated or a plurality of lifting composite belts are used side by side in the use process are avoided, and the safe, stable and efficient operation of the friction type mine lifting system is ensured. The upper base of the trapezoid refers to the lower base of the trapezoid, which has a smaller length, and the lower base refers to the lower base of the trapezoid, which has a larger length.
According to another embodiment of the present invention, when the mine hoisting composite belt is used, the number of the mine hoisting composite belt can be one or more, when the mine hoisting composite belt is one, as shown in fig. 2, the width W of the mine hoisting composite belt can be 800-3000 mm, the thickness d can be 10-80 mm, at this time, the number of the steel wire ropes 20 or the high-performance fiber ropes 20 in the hoisting composite belt can be 30-150, and the diameter of the single steel wire rope 20 or the single high-performance fiber rope 20 can be 3-30 mm; when the number of the lifting composite belts is multiple, the multiple lifting composite belts are used side by side on the friction wheel, the width W of each lifting composite belt can be 100-800 mm, the thickness d can be 10-80 mm, the number of the steel wire ropes 20 or the high-performance fiber ropes 20 in each lifting composite belt can be 8-30, and the diameter of a single steel wire rope 20 or a single high-performance fiber rope 20 can be 3-30 mm. The inventor finds that with the increase of lifting height and the increase of lifting load, the diameter of a required steel wire rope and the diameter of a corresponding friction wheel are correspondingly increased, so that the efficiency of a lifting system is reduced, and under the same lifting height and load requirements, the diameter of a required single steel wire rope and the diameter of a corresponding friction wheel can be obviously reduced by adopting a lifting composite belt instead of the lifting steel wire rope. Preferably, when the mine hoisting composite belt is a single belt, the width W of the mine hoisting composite belt may preferably be 800-1000 mm, and the number of the steel wire ropes 20 or the high-performance fiber ropes 20 in the mine hoisting composite belt may preferably be 30-50, thereby being more beneficial to transportation and installation of the hoisting system on the basis of ensuring that the hoisting composite belt has sufficient loading capacity and mechanical property. According to a specific example of the invention, the length of the mine hoisting composite belt can be 850-3100 mm, and the load range can reach 10-65 t. In the invention, when the cross section of the mine hoisting composite belt is trapezoidal, the width of the mine hoisting composite belt is the width of the upper bottom, the upper bottom and the lower bottom both meet 800-3000 mm, and the thickness is the vertical distance between the upper bottom and the lower bottom.
According to yet another embodiment of the present invention, the outer covering material 10 may further include a high performance fiber web, thereby not only further improving the load carrying capacity of the mine hoisting composite belt, but also effectively avoiding excessive falling-off of the outer covering material 10 when locally aged or bumped.
According to still another embodiment of the present invention, the outer covering material 10 may include a polymer material and optionally an organic reinforcing material, and preferably, the polymer composite material may include at least one selected from polyurethane, rubber, and resin. The inventor finds that the toughness and the friction coefficient of the mine hoisting composite belt can be further improved by selecting the polymer material, so that the hoisting efficiency of a hoisting system can be further improved, and the service life of the mine hoisting composite belt can be prolonged.
According to still another embodiment of the present invention, the kind of the high performance fiber rope 20 is not particularly limited, and a person skilled in the art may select according to actual needs, for example, the high performance fiber rope 20 may be at least one selected from the group consisting of a carbon fiber rope, a polyethylene fiber rope, an aramid fiber rope, a nylon fiber rope, a polyester fiber rope and a polypropylene fiber rope, thereby enabling the mine-lifting composite belt to have higher tensile strength and lower quality.
The invention will now be described with reference to specific examples, which are intended to be illustrative only and not limiting in any way.

The lifting height is 1950m, the self weight of the lifting container is 30t, and the normal load is 10t. The friction type mine hoist with 6 mine hoisting composite belts is adopted, the section size of the hoisting composite belts is 230mm multiplied by 28mm (width multiplied by thickness), the diameter of a single steel wire rope in the hoisting composite belts is 20mm, and the diameter of a friction wheel of the friction type mine hoist is 2.8m.
Example 2

Conclusion: compared with the prior art, under the same lifting condition, the diameter of a single steel wire rope required by the elevator and the diameter of a corresponding friction wheel can be obviously reduced by replacing the lifting steel wire rope with the lifting composite belt, so that the dead weight and the volume of the elevator can be reduced, and the installation of the elevator is facilitated, and the lifting efficiency is further improved.
