Abstract
A tapered-face friction buffer comprises a rotary shaft. wherein friction cones are sleeved at the two ends of the rotary shaft; friction tapes are arranged on the external surfaces of the friction cones; rollers are sleeved in the middle of the rotary shaft and outside the friction tapes; fixing rope clamps are arranged on the rollers; and one end of a steel wire rope wound on the external surfaces of the rollers is fixed on the rollers through the fixing rope clamps. As the friction surfaces among the rollers and the friction cones are tapered-face bodies, the friction area is enlarged, therefore, the friction force is increased; the steel wire rope is wound on the rollers and has the function of buffering through the transmission of the rollers, so that the service life of the steel wire rope is greatly prolonged. The tapered-face friction buffer adopts single resistance to offset and reduce the work done by motive power, thereby exerting the buffering effect; the buffering performance is strong; and no damage is caused to the hoisting of the steel wire rope; and the tapered-face friction buffer reduces the consumption of raw materials, thereby lowering the production cost. The tapered-face friction buffer is applied to coal mine enterprises.
Description
Technical field
The utility model relates to a kind of buffer, and it is strong and to the harmless conical surface friction buffer of boom hoist cable to relate to a kind of shock-absorbing capacity specifically.
Background technique
At present, the buffer that uses on the market is of a great variety, and compression spiral shock-absorbing spring series, rubber buffer structure etc. are arranged, and industry all buffer in colliery generally is to utilize the buffer function of having moved that wire rope bending deflection resistance and frictional force does as shown in Figure 1.The sort buffer device can reach certain buffer function, but bigger to the strong infringement of steel wire, wire rope can not be reused, and the replacing of wire rope is frequent, the cost of production height.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of conical surface buffer is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of conical surface friction buffer, comprise rotating shaft, the rotating shaft two ends are arranged with friction cone, the outer surface of friction cone is provided with the friction band, be arranged with roller at the middle part of rotating shaft and the outside of friction band, establish fixedly rope clamp on the roller, an end that is wrapped in the wire rope on the roller outer surface fixes on the roller by the static line clamping.
Above-mentioned conical surface friction buffer, described wire rope uniform winding is on roller.
Above-mentioned conical surface friction buffer, described friction band is by being bolted on the friction cone.
Above-mentioned conical surface friction buffer, the built-up welding of described friction band is on friction cone.
Adopt technique scheme, the utility model has following advantage: because the rubbing surface between roller and the friction cone is a conical surface body, increased friction area, thereby increased frictional force, wire rope is wrapped on the roller, play buffer function by the roller transmission, greatly director the working life of steel wire rope.The utility model adopts single resistance to reduce the merit that power is done, thereby plays buffer function, and shock-absorbing capacity is strong and harmless to boom hoist cable.Reduce raw-material consumption, thereby reduced cost of production.The utility model is applied to coal mining enterprise.
