Abstract
The utility model relates to a stabilizer of a crane, belonging to the load hanging device of the crane. A stabilization drum on a crane carriage is made into a section with unequal diameters; the stabilization drum is interlinked with a main lifting drum; a hanger is provided with a mechanical friction mechanism, wherein, braking block (18) is pressed on a braking wheel through a spring (16) to generate constant friction force; the whole device has no additional power. The utility model has the advantages of simplicity, legerity, reliability, convenient maintenance, etc. The utility model is suitable for the stabilization of container cranes, such as railways, harbors, etc. and other kinds of crane hanging load. The stabilizer of a crane can improve loading efficiency, reduce the damage of a container and ensure transportation safety.
Description
This is suitable for the novel load erecting by overhang that belongs to hoisting crane.
In the container hanging operation, for reducing shaking of suspender and casing, to case, entrucking, minimizing clashing and breaking, to raise the efficiency fast, the specific purpose container hoisting crane is provided with antirolling apparatus usually.The general more complicated of antirolling apparatus of external hoisting crane, and additionaling power device or hydraulic efficiency pressure system.According to the characteristics of China's freight container traffic, antirolling apparatus should be simple and reliable as far as possible.The flexible antirolling apparatus of simple type was once arranged in the past, adopted the power consumption of hydraulic damping system on the suspender, and, gave and use and maintenance is made troubles because hydraulic oil leaks easily.
The present invention is provided with friction mechanism consumption to shake mechanical energy on suspender, and without the hydraulic damping system, thereby do not have leakage problem.
Fig. 1 is the lifting mechanism on the dolly and subtracts swing mechanism; Fig. 2 subtracts to shake steel rope winding schematic diagram; Fig. 3 is the friction mechanism on the suspender.［ 1 ］-supporting among the figure; ［ 2 ］-leading sheave; ［ 3 ］-subtract and shake reel; ［ 4 ］-electrical motor; ［ 5 ］-drg; ［ 6 ］-reductor; ［ 7 ］-coupler; ［ 8 ］-hoisting drum; ［ 9 ］-supporting; ［ 10 ］-gear; ［ 11 ］-subtract and shake steel rope; ［ 12 ］-chain; ［ 13 ］-spring; ［ 14 ］-leading sheave; ［ 15 ］-axle; ［ 16 ］-retarding spring; ［ 17 ］-brake wheel; ［ 18 ］-and brake shoe, ［ 19 ］-overriding clutch; ［ 20 ］-sprocket wheel.Subtract and shake reel ［ 3 ］ and drive by a pair of gear transmission, subtract and shake steel rope ［ 11 ］ and be connected on the chain ［ 12 ］ through leading sheave ［ 2 ］ and ［ 14 ］ by hoisting drum ［ 8 ］.When suspender hoisted, motor drives master's hoisting drum ［ 8 ］ and subtracting shook reel ［ 3 ］ and rotates, and each reel twines raising line respectively and subtracts and shakes rope.Change with spreader height owing to subtract the angle that shakes rope and horizontal surface, the speed of winding also changes at any time, and raising line then twines with the constant speed rate, exists asynchronous between two ropes.Subtract and shake reel ［ 3 ］ and make non-equal diameter cross section, to shake rope synchronous with raising line to keep subtracting, and promptly (suspender does not have when shaking) sprocket wheel ［ 20 ］ does not rotate basically in lifting process.When suspender shakes, distance between suspender and pulley ［ 2 ］ is tending towards increasing subtracting of a side and shakes rope ［ 11 ］ pulling chain ［ 12 ］, and by sprocket wheel ［ 20 ］ overriding clutch ［ 19 ］ drive axle ［ 15 ］ and brake wheel ［ 17 ］ along n to rotation, like this, shaking mechanical energy makes between brake wheel and brake shoe and produces fricting movement, mechanical energy is transformed into heat energy and dissipates, and shakes and weakens.Subtracting of a lax side shaken rope then by spring ［ 13 ］ tension, and overriding clutch this moment ［ 19 ］ is thrown off, sprocket wheel idle running.The pulling force of spring ［ 13 ］ is little, shakes rope and does not take place laxly as long as make to subtract, and can to obtain enough big friction force, make to shake to stop in few time of trying one's best according to shaking situation regulating spring ［ 16 ］.
The structure of this cover antirolling apparatus is light and handy, reliable in action, the stabilizing efficiency scalable, easy to manufacture, need not additionaling power, energy-conservation, and do not have hydraulic oil, can not produce leakage, actual requirement is produced in the comparison operators symphysis, mainly be used on the container handling cranes such as railway, harbour, traffic, can reduce clashing and breaking greatly, and improve handling efficiency.
Claims (3)
1, a kind of crane hanger antirolling apparatus is made up of the lifting mechanism on the crane carriage and the friction mechanism two parts on the suspender.It is characterized in that subtracting of crane carriage shakes between reel [3] and the main hoisting drum [8] links up with gear transmission or retarder etc., and the two is maintained fixed transmitting ratio, subtracts to shake reel and make non-equal diameter cross section; Adopt mechanical friction mechanism to consume on the suspender and shake mechanical energy.
2, by the described antirolling apparatus of claim 1, it is characterized in that friction mechanism medi-spring ［ 16 ］ is pressed on brake block ［ 18 ］ on the brake wheel ［ 17 ］, produce constant friction resistance moment, and mechanical energy is shaken in consumption.
3, by the described antirolling apparatus of claim 1, it is characterized in that subtracting and shake rope ［ 11 ］ and walk around assembly pulley ［ 14 ］, pulling chain ［ 12 ］, through overriding clutch ［ 19 ］, make friction wheel ［ 17 ］ along n to rotation, and shaking rope ［ 11 ］ when lax trend is arranged when subtracting, spring ［ 13 ］ pulling chain ［ 12 ］ makes to subtract through overriding clutch and shakes rope ［ 11 ］ tensioning, at this moment overriding clutch transfer torque not.
