The balance-adjustable floating head sheave device is simple in overall structure and reasonable in design, the two floating head sheave device bodies are connected with two hydraulic stations respectively without mutual interference, oil cylinders in the two floating head sheaves can be independently adjusted, the positions of the floating head sheaves are adjusted through adjusting oil pressure of the oil cylinders, and then the tension of steel wire ropes wound around the floating head sheaves is adjusted. Meanwhile, adjusting is convenient, rapid and accurate, and working efficiency is greatly improved.
Description
Technical field
The invention belongs to mine hoist technical field, particularly relate to the floating head sheave apparatus of a kind of multi-rope winding type gig adjustable balance.
Background technology
Multi-rope winding type gig is the equipment being applicable to superdeep well lifting, its structure as shown in Figure 1, generally mostly be two steel ropes 1 and be with a lifting container 2, because two steel ropes 1 are with same lifting container 2, because a variety of causes (as reel Mismachining tolerance, wirerope diameter is poor, steel rope modulus is poor, steel rope interlayer overexercise is asynchronous) there will be the phenomenon of the tension imbalance of two steel ropes 1, must take measures to reduce unbalanced difference as far as possible.
For reducing the difference of the tension imbalance of two steel ropes, the method that multi-rope winding type gig is taked is the scheme of installing the movable pulley that floats above lifting container, because floating movable pulley must follow rope footpath to refer to floating movable pulley diameter than D/d(D, d refers to the diameter of steel rope) requirement, diameter is large, Heavy Weight, cause and have to reduce capacity weight on steel rope, so adopt the scheme of movable pulley to have very large defect.
Summary of the invention
In order to solve existing multi-rope winding type gig two unbalanced problems of steel wire rope tension when promoting, the object of this invention is to provide the floating head sheave apparatus of a kind of multi-rope winding type gig adjustable balance, adjust separately every root steel wire rope tension on it by the position adjusting floating head sheave, make the tension force of two steel ropes reach balance.
In order to realize foregoing invention object, this wiping name adopts technical scheme as described below:
A kind of floating head sheave apparatus of multi-rope winding type gig adjustable balance, it comprises two groups of floating head sheave apparatus be arranged in parallel, often the floating head sheave apparatus of group comprises floating head sheave, U-shaped framework, cylinder apparatus, line slideway and support, head sheave of floating is arranged on by the adapter shaft worn in its centre hole between the two side of U-shaped framework, and the bottom of U-shaped framework is connected with cylinder apparatus.
Further, often the floating head sheave apparatus of group also includes support, the biside plate of support lays respectively at the outside of the two side of U-shaped framework, and line slideway is respectively arranged with on the madial wall of support biside plate, the outside of the two side of U-shaped framework is installed with a slide block respectively, and two slide blocks lay respectively in the guide rail of respective side.
Further, described cylinder apparatus is made up of oil cylinder, displacement pickup and oil pressure sensor.
Further, described cylinder apparatus is circumscribed with the Hydraulic Station for driving cylinder action.
Owing to adopting technique scheme, the present invention has following preceence:
Integral structure of the present invention is simple, reasonable in design, two groups of head sheave apparatus that float connect a Hydraulic Station separately, do not interfere with each other, independently can adjust two groups of oil cylinders floated in head sheave, adjusted the position of floating head sheave by the oil pressure adjusting oil cylinder, and then adjustment is wrapped in the tension force of the steel rope in floating head sheave; Meanwhile, easy to adjust, quick, accurate, substantially increase work efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 2, a kind of floating head sheave apparatus of multi-rope winding type gig adjustable balance, it comprises two groups of floating head sheave apparatus be arranged in parallel, often the floating head sheave apparatus of group comprises floating head sheave 1, U-shaped framework 2, cylinder apparatus 3, line slideway 5 and support 4, head sheave 1 of floating is arranged on by the adapter shaft worn in its centre hole between the two side of U-shaped framework 2, and the bottom of U-shaped framework 2 is connected with cylinder apparatus 3.
Often the floating head sheave apparatus of group also includes support 4, the biside plate of support 4 lays respectively at the outside of the two side of U-shaped framework 2, and line slideway 5 is respectively arranged with on the madial wall of support 4 biside plate, the outside of the two side of U-shaped framework is installed with a slide block respectively, and two slide blocks lay respectively in the line slideway of respective side.
Described cylinder apparatus 3 is made up of oil cylinder, displacement pickup and oil pressure sensor.
Described cylinder apparatus 3 is circumscribed with the Hydraulic Station for driving cylinder action.
The sidewall of described slide block and U-shaped framework can be set to integrative-structure, or the sidewall of U-shaped framework is processed as the structure suitable with line slideway.
Adjustment principle of the present invention is:
The external Hydraulic Station respectively of two cylinder apparatus in the present invention, drive each cylinder apparatus respectively by two Hydraulic Stations, the Hydraulic Station oil circuit connecting each cylinder apparatus is independently, and the oil pressure of Hydraulic Station every bar oil circuit all passes through independent apportioning valve adjustment.If the oil pressure that cylinder apparatus detects is on the low side, illustrate that in the floating head sheave corresponding with it, steel wire rope tension is less than normal, then oil pressure is heightened by passing ratio valve, and oil cylinder overhang strengthens, and tension force on steel rope is strengthened; If the oil pressure that cylinder apparatus detects is higher, in the floating head sheave that its correspondence is described, steel wire rope tension is bigger than normal, and then oil pressure is turned down by passing ratio valve, and oil cylinder overhang reduces, and then tension force on steel rope is reduced; By this adjustment mode, cylinder apparatus can be made to adjust in real time, thus reach the two steel wire rope tensions maintenance balances be wrapped in respectively in each floating head sheave.
It should be noted that, the cylinder apparatus that the present invention adopts is the shaped article of oil cylinder, displacement pickup, oil pressure sensor integration.Line slideway adopts the existing structure built with steel ball, and the friction force between slide block and guide rail is little, except straight-line motion, can also bear the load in other direction.
