Description
Technical field
The utility model relates to equipment hoisting technical field, more particularly, relates to a kind of Lift-on/Lift-off System of ground control decoupling device.
Background technology
Installation is on-the-spot, the lifting hanger of most tower class and vertically-arranged tank kind equipment is all set to the board-like hanger in top, during lifting, main hoisting crane is promoted by hoist cable connecting device top two-plate hanger, device bottom is sent by whipline slipping tail, until equipment is upright, extract auxiliary Current Collector Sleave, the independent hanging device of main hoisting crane is in place.
The work of equipment rear excision Current Collector Sleave in place needs high-altitude to carry out, for hanger height within six meters, general all employing erects vertical ladder, workman arrives equipment top by cat ladder, extract the pivot pin between shackle and equipment hanger, for hanger height more than six meters, often use crane lifting hanging basket, workmen is hung on equipment top, carry out the excision of shackle pivot pin.But by artificial ascend operation, have certain security risk, in some foreign-funded projects, safety management performs by international standard, and this class behavior is absolute prohibition.They are according to the customary practice of advanced country, workman is ascended a height by folding-jib aerial platform and carries out the excision of shackle pivot pin, and most camp site at home, the basic configuration not construction machinery and equipment of this type of advanced person, if adopt the on-the-spot method setting up operation scaffold to carry out decoupling device operation, for the equipment of height at 25 meters, tens scaffolders often just can complete setting up of full hall scaffold in one day, main hoisting crane does not pluck hook because of equipment, and idle one day, cause the waste of great construction machinery and equipment expense, the waste of scaffolder's man-hour and material lease expenses, constrain engineering construction progress.
Through retrieval, the technical scheme that can solve the problem in the mode of terrestrial operation decoupling device has been there is in prior art, being pulling rope makes the disengaging of shackle pivot pin unload body, its decoupling device method is various, but all shackle body is transformed, damage shackle internal organizational structure, change shackle design strained condition.Chinese Patent Application No.: ZL201320320530.5, the applying date: on June 5th, 2013, invention and created name is: terrestrial operation lifting shackle, this application case is for solving people for a difficult problem for high-altitude shackle and designing, the opening retainer side bottom of shackle is the fore shaft being provided with pin-and-hole, fore shaft lateral surface linking springs case, spring box both ends of the surface are provided with through hole, this through hole same footpath concentric on the pin-and-hole of opening retainer fore shaft.Bearing pin penetrates from spring box end face through hole, and suit is positioned at the spring of case and is set with fixed dam, and end part of pin shaft is provided with radial pin-and-hole.Opening retainer is provided with turning circle.The fraud place of this way: the first, welds spring box unloading on body, has damaged and unloaded body internal organizational structure, there will be invisible crackle, directly affects the intensity of shackle; The second, pivot pin does not re-use the longitudinal travel that screw thread controls pivot pin, and the friction force just produced by heavy duty stops the longitudinal travel of pivot pin, is unfavorable for safty hoisting; 3rd, the pivot pin of replacing, in smooth shape, has run counter to the design concept (in shackle use procedure, pivot pin screw thread position should screw in completely and unload body, to ensure bulk strength and the stability of shackle) of shackle, has been unfavorable for safty hoisting.
