Description
Technical field
The invention belongs to the anti-of elevator machinery and shake suspension bracket field, particularly relate to a kind of automatic cabinet track crane eight and restrict added.
Background technology
During hoisting crane transport operation, large and small car operation can produce starting and braking acceleration/accel, and the goods under suspension centre is rocked, and driver cannot carry out getting immediately, unloading work, thus makes dust cycle lengthen, and production efficiency declines.Therefore how to prevent shaking be all hoisting cranes all will faced by problem.
The anti roll device that hoisting crane is conventional is divided into mechanical type, fluid pressure type, electronic type three class.Mechanical type refers to that utilizing theory of machines to subtract shakes or prevent shaking, and point rigidity and flexible two large classes, mainly contain rigidity guide braking (rigidity), separation chassis (flexibility) and three kinds, Eight characters rope system (flexibility); Fluid pressure type refers to the anti-sway system by hydraulic ram propelling sheave group; Electronic type refers to the anti-sway system relying on electric braking control principle completely.Wherein, mechanical eight rope anti-sway systems are owing to can simultaneously two-wayly in large and small car direction anti-ly to shake, and its steel wire rope tension center is close to load center, anti-shake reliable for effect effectively and approve by increasing people.
Current many harbour machineries have used this type of anti-sway system, not only efficiently solve the flapping issue of suspender, and in the handling machinery of the special suspender of all bands all great popularization.Eight rope anti-sway systems of present main flow are divided into " inverted-triangular " and " triangular " two kinds.These two kinds of systems all utilize leg-of-mutton stability principle, change four traditional pulley lifting winding systems into multiple identical triangular system.Their horizontal component of force prevents suspender waving on cart and dolly direction, improves the rigidity of Suspension System.
But, above-mentioned triangle eight is restricted and is prevented shaking structure when crane travel mechanism acceleration, deceleration campaign, when load is waved, steel rope can be tight suddenly, producing the moment antagonistic force contrary with waving direction, because system performance is too firm, causing steel rope often to bear instantaneous impulsive force, easily cause fracture of wire, shorten the service life of steel rope.
As can be seen here, prior art awaits further improving.
Summary of the invention
The present invention is the weak point avoiding above-mentioned prior art to exist, provide a kind of can effective prolonging service life of steel wire and the automatic cabinet track crane eight possessing rocking-prevention function is restricted added.
The technical solution adopted in the present invention is:
A kind of automatic cabinet track crane eight is restricted added, comprise added pedestal, added pedestal comprises four crossbeams, the top of every root crossbeam is provided with the first guide rail, can along the shifting board of the first guide rail slippage, for the driver train driving the shifting board on this crossbeam to do straight-line motion, the top of each shifting board has been provided with hanging part, each hanging part includes two discrete turnbuckles and is arranged on the hoist rope on top of each turnbuckle, the bottom of each turnbuckle is all connected with shifting board, belong to a top of playing two turnbuckles in hanging part together to be connected by stretch cord, each hanging part is at two turnbuckles, the type of falling A structure is formed under the cooperation of two hoist ropes and a stretch cord.
The side of each described turnbuckle is provided with cushioning supportive mechanism, cushioning supportive mechanism comprises steel spring, the lowermost end of steel spring is connected with the top of shifting board, U-bolt colligation is passed through on turnbuckle in the middle and lower part of steel spring, the top of steel spring is provided with bump rubber, and bump rubber is between turnbuckle and steel spring.
