Abstract
The utility model discloses a universal crane for metallurgy with double independent wire ropes. The universal crane comprises a lifting wound roll, a wire ropes and pulleys. The two ends of each steel wire rope are wound around the two ends of the lifting wound roll respectively; the middle part of each steel wire rope passes through an upper fixed pulley; fixing devices are arranged on the steel wire ropes close to the two sides of the fixed pulley respectively; a blocking device is arranged in the vicinity of the fixed pulley; a left independent wire rope and a right independent wire rope are respectively formed on the two sides of the fixed pulley; a lifting hook pulley block is arranged below the left and the right independent wire ropes respectively; a dedicated hanging appliance is arranged below each of two lifting hook pulley block; and an articulated shaft is respectively arranged at the two ends and the middle part of each dedicated hanging appliance, wherein, the articulated shafts at the two ends of each dedicated hanging appliance are connected with a left lifting hook and a right lifting hook through two connecting pieces respectively, and the articulated shaft at the middle part thereof is provided with a lower lifting hook. The utility model has the advantages of simple structure, low cost, good safety performance and the like; and when one steel wire rope is broken, the other steel wire rope can independently hang a steel ladle, thereby gaining the time of personnel evacuation, and safely placing the steel ladle on the ground.
Description
Technical field
The utility model belongs to the elevator machinery class, a kind of universal crane that is used for metallurgy.
Background technology
The common universal crane that is used for metallurgy being provided with of hoist rope, only has an independent steel rope by some assembly pulleys, reaches the requirement of the safety factor of steel rope carrying in the mode that increases multiplying power.This root independence steel rope is in the process of handling molten metal, bearing hyperthermia radiation and the heavy duty effect of reverse stress and splashing of fusing molten steel down, be easy to take place the diameter that fracture of wire, disconnected strand and other reasons cause and reduce phenomenon, the steel rope load-carrying capacity is descended, as can not in time finding and change, rope-broken accident will appear.Steel rope is in case fracture, come one after another and inevitably the steel ladle grave accident of toppling take place.The personnel that can't win when the time comes withdraw the time with safe disposal molten steel storehouse.
Summary of the invention
The purpose of this utility model provides a kind of metallurgical universal crane that is used for two independent steel ropes, so that when disconnected rope phenomenon takes place steel cable therein, the personnel of winning flee the scene and time of safe disposal steel ladle.
The technical solution of the utility model is such:
1, the utility model is made up of hoisting drum, steel rope and pulley.Around the two ends of hoisting drum, upper static pulley is passed in the centre respectively at steel rope two, and wire rope fixing device respectively is set near the steel rope the fixed pulley both sides, and stop device is set near the fixed pulley.The both sides of fixed pulley promptly constitute left independent steel rope and right independent steel rope.About the below of independent steel rope an independently lifting hook pulley group respectively is set, a special-purpose hanger is set below two lifting hook pulley groups.Special-purpose hanger two ends and centre respectively are provided with a jointed shaft, and the two ends jointed shaft respectively is connected with left and right sides suspension hook respectively by two attaching partss; Middle jointed shaft is provided with a underlying suspension hook.
2, above-mentioned attaching parts is the loop chain attaching parts.
The universal crane that is used for metallurgy of two independent steel ropes is at operational process, when wherein disconnected rope (two disconnected simultaneously probability of restricting of steel rope are very small) takes place in steel cable, another root steel rope can hang steel ladle separately, thereby won the time of evacuating personnel, and steel ladle safety can be put on the ground.The utlity model has simple in structurely, advantage such as cost is low, and safety performance is good is applicable to the technological change at the universal crane of usefulness simultaneously.
Description of drawings
Fig. 1 is the metallurgical universal crane constructional drawing that is used for of the two independent steel ropes of the utility model;
Fig. 2 is the working state figure before the disconnected rope of the utility model one side suspension hook and special-purpose hanger;
Fig. 3 is the working state figure behind the disconnected rope of the utility model one side suspension hook and special-purpose hanger.
In the accompanying drawing, hoisting drum (1), upper static pulley (2), wire rope fixing device (3), stop device (4), a left side independent steel rope (5), right independent steel rope (6), lifting hook pulley group (7), special-purpose hanger (8), jointed shaft (9), attaching parts (10), underlying suspension hook (11), steel ladle (12).
The specific embodiment
With reference to accompanying drawing, the utility model is made up of hoisting drum, steel rope and pulley.Steel rope two is respectively around hoisting drum (1) two ends, upper static pulley (2) is passed in the centre, on near the upper static pulley both sides the steel rope wire rope fixing device (3) is set respectively, stop device (4) is set near the fixed pulley, and the fixed pulley both sides promptly constitute left independent steel rope (5) and right independent steel rope (6).About the below of independent steel rope an independently lifting hook pulley group (7) respectively is set, special-purpose hanger (8) is set below two lifting hook pulley groups.These special use hanger two ends and centre respectively are provided with a jointed shaft (9), and the two ends jointed shaft respectively is connected with left and right sides suspension hook respectively by two attaching partss (10).Middle jointed shaft is provided with a underlying suspension hook.Above-mentioned attaching parts (10) is the loop chain attaching parts.Every independent steel rope must tool foot regulation load-carrying capacity, with tackle must the time the state that works alone.It is close that two lifting hook pulley groups should be tried one's best, and be on the same level attitude.Special-purpose hanger lateral dimension is short as far as possible, to reduce the impact load that disconnected rope causes.Among Fig. 2 the α angle should greater than 30 the degree, favourable to the horizontal pull that reduces attaching parts.
Claims (2)
1, a kind of universal crane that is used for metallurgy of two independent steel ropes is made up of hoisting drum, steel rope and pulley, it is characterized in that steel rope two respectively around the two ends of hoisting drum (1), and upper static pulley (2) is passed in the centre; On near upper static pulley (2) both sides the steel rope wire rope fixing device (3) is set respectively, stop device (4) is set near the fixed pulley, upper static pulley (2) both sides promptly constitute left independent steel rope (5) and right independent steel rope (6); About independent steel rope below an independently lifting hook pulley group (7) respectively is set, the below of two lifting hook pulley groups is provided with a special-purpose hanger (8); The two ends of described special-purpose hanger (8) and centre respectively are provided with a jointed shaft (9), and the two ends jointed shaft respectively is connected with left and right sides suspension hook respectively by two attaching partss (10), and middle jointed shaft is provided with a underlying suspension hook (11).
2, according to the metallurgical universal crane that is used for of the described two independent steel ropes of claim 1, it is characterized in that attaching parts (10) is the loop chain attaching parts.
