Description
Technical field
The utility model relates to a kind of rope guide, and especially a kind of matching used rope guide of winch used with boiler hearth overhauling platform, the utility model belongs to technical field of engineering machinery.
Background technology
Winch is the weight-lifting equipment of a kind of reel lay winding wire ropes or chain lifting or traction weight, also known as winch.The perfect condition of winch when rolling steel rope is: steel rope from left to right order is wound around ground floor on reel, then right-to-left order is wound around the second layer on reel again, and so forth until steel rope all in order smooth be in layer wound around on reel.
But often actual conditions are unsatisfactory, when steel rope is wound around on reel, because of a variety of causes: as comparatively large in steel rope rope angle, the own distortion of steel rope etc., disorder cable phenomenon can be there is when steel rope is wound around on reel, it is mainly manifested in: steel rope not yet arrives termination when S layer is wound around, namely not yet arrive last lap, be just wound on S+1 layer, or be repeatedly wound around etc. in reel section.If winch is rolling steel cable only, the result of disorder cable is just visually felt to arrange unordered, to decrease reel appearance at the most rope amount, does not affect the normal work of winch, more can not cause danger.
But for the winch that boiler hearth overhauling platform uses, need to use many steel ropes to lift by crane a yardstick large, load is heavy, the large platform of lifting distance tens meters simultaneously.Large platform is loaded with again several maintainer, is an equipment with being in extreme danger property.Even if when equipment quality itself does not have problems, due to the disorder cable phenomenon occurred during rolling steel rope, inspection platform also may be caused to tilt to cause danger.
Here for six roots of sensation steel rope, because winch has six roots of sensation root wire rope suspensioning inspection platform, when interim plane assembling inspection platform, the suspension centre adjusted of six steel ropes is on a horizontal surface.When lifting drum rolling steel rope, if wherein one or a few steel rope rolling is to the length on reel more than other several steel ropes, the suspension centre of six roots of sensation steel rope will no longer be on same horizontal surface, and whole inspection platform will lose planarization, or produce, or produce convex-concave.Along with inspection platform constantly raises, inclination or convex-concave will be further serious.
The furnace width of inspection platform and furnace depth many between 13 meters ~ 19 meters, the furnace width of 1,000,000 unit boilers and furnace depth reach more than 21 meters.The inspection platform winch of 1000000 unit boilers is when lay winding wire ropes, as long as there be the S+1 layer of steel cable from the S layer pre-wound of reel to reel, reel revolves and turns around, and this root steel rope will be wound around 12.5cm more on reel, and this suspension centre edge will higher than inspection platform horizontal surface 15cm.Often this steel rope can continue again pre-wound to S+2 layer, S+3 layer ..., so accumulate, this rope will be wound around 60 ~ 90cm more.
Large-tonnage, more hold rope amount, particularly many rope races and require many winchs consistent with steel rope rope closing speed, should rope guide be set, guarantee that steel rope marshalling, all rope speeds are consistent, the row's of preventing rope entanglement, system ability reliable operation, safe operation.
For boiler hearth overhauling platform, if be simple use winch and there is no rope guide, the planarization of platform will be had a strong impact on, injure the personal safety of service personnel.
