Description
Technical field
The present invention relates to duplex type multiple wraps formula rope hoisting system; Particularly relate to a kind of Wire Rope Used in Lifting equalization of strain self-checking device.
Background technology
The exploratory development of Deep Minerals, the grand strategy having become the many national developments comprising China is selected.Employing duplex type multiple wraps formula rope hoisting system (i.e. BLAZER elevator system) is effective pattern of superdeep well hoisting device.
Due to the feature such as heavy duty, high speed, large inertia of ultra-deep mine hoisting equipment, the periodic perturbation that Wire Rope Used in Lifting produces in high-speed coiling process, winding error etc. can cause the distortion off resonance of rope hoisting system, cause and carry fortune steel wire rope tension extremely, cause system cisco unity malfunction.Current in the duplex type multiple wraps formula rope hoisting system of superdeep well application, the general problem adopting single-sheaved block scheme and floating head sheave scheme to solve equalization of strain adjustment.The head sheave solution technique that wherein floats is not mature enough, and complex structure, manufacture and tooling cost high, not easily install and change, in addition, head sheave scheme of floating has adjustment delay time error, and floating head sheave scheme regulates too fast, can produce driving source at head sheave place, greatly will increase the vibration of steel rope, not only can not reduce steel wire rope tension difference, can Tension Difference be aggravated on the contrary, thus the object of out of reach tension adjustment.Therefore more employing single-sheaved block schemes carry out balance adjustment in prior art.
Single-sheaved block scheme refers to fixes a single-sheaved block on lifting container, and then connected two steel rope lower ends and be wrapped on single-sheaved block, like this, two steel ropes can pass through single-sheaved block slide control, to make its equalization of strain.
But adopt this single-sheaved block regulation scheme, according to the regulation of " safe coal code ", namely drum diameter and seizing wire diameter ratio are more than or equal to certain particular value (being generally be more than or equal to 90), to control the flexure stress of steel rope in safe range, but due in superdeep well lifting, in order to increase effective lifting load, the diameter of main Wire Rope Used in Lifting just must be increased.Meet afore mentioned rules, then movable pulley diameter is also with regard to increase at double, causes the diameter of movable pulley excessive, and then adds the weight of control apparatus, reduce effective lifting load.If the effective diameter of artificial reduction pulley, then steel rope flexure stress will increase, and flexural fatigue phenomenon increases the weight of, and rope service-life shortens.In addition, because swing when single action pulley regulation scheme regulates is large, easily produce chute, the vibration simultaneously in control process is strong, and impact resistance is weak, without safety guard, and poor stability.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical matters to be solved by this invention is: how to provide one effectively can regulate two Wire Rope Used in Lifting Tension Difference, governing response is fast, do not have delay time error, effective diameter is little, and Adjustment precision is high, adjustment process is steady, there is spacing and anti-drop function, strong shock resistance, the Wire Rope Used in Lifting equalization of strain self-checking device that safety is high.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
