The crane jib horizontal course changing pulley block is connected with two crane jib head course changing pulleys by steel wire ropes, the two crane jib head course changing pulleys are wound into a main hook directional pulley block by steel wire ropes, the main hook directional pulley block is connected with a main hook movable pulley block, the two ends of the main hook directional pulley block are connected with horizontal course changing pulleys by steel wire ropes, a balance force measuring pulley is connected between the two horizontal course changing pulleys by a steel wire rope, a force measuring sensor is arranged on the balance force measuring pulley, and a main hook is suspended below the main hook movable pulley block by a cross beam. The utility model has the advantages of simple structure and little possibility of making the steel wire ropes slip out.
Description
Technical field:
The utility model relates to a kind of later-model crane barge master lifting and winding system that is used for, and is applied to heavy-duty machinery field, harbour, Logistics Equipment, heavy industry field, ocean.
Background technology:
In traditional main lifting and winding system, the main hook steel rope generally all is from main two the reel rope stretchings that hoist, subsequently respectively by Shears changed course assembly pulley, jib middle part changed course assembly pulley, the main hook fixed pulley group that jib head changed course assembly pulley enters the jib head, because when steel rope enters main hook fixed pulley group, two pulley rooms are apart from less, steel rope alters course assembly pulley from jib middle part changed course assembly pulley around to main hook fixed pulley group the time through the jib head, pulley room is bigger apart from changing, therefore the deflection angle of rope in the crane barge main hook pulley system is bigger, and steel rope is easy to jump out from pulley groove.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, a kind of later-model main lifting and winding system is provided, compact conformation, pattern is succinct, drift angle between jib middle part changed course assembly pulley, jib head changed course assembly pulley and the steel rope is reduced, the main lifting and winding system that steel rope is difficult for skidding off.
The purpose of this utility model is achieved through the following technical solutions: a kind of main lifting and winding system, comprise two main hook hoisting drum groups, two main hook hoisting drum groups are placed side by side, two main hook hoisting drum groups all are connected with the changed course pulley by steel rope, be connected with the steel rope that is broken line shape between two changed course pulleys, and each changed course pulley all is connected with jib middle part changed course pulley by steel rope, two jib middle part changed course pulleys all are connected with one group of jib horizontally redirectional assembly pulley jointly by steel rope, jib horizontally redirectional assembly pulley is connected with two jib head changed course pulleys by steel rope, two jib head changed course pulleys move into the directed assembly pulley of a main hook by steel rope and are connected with a main hook running block, the main hook running block places the bottom of the directed assembly pulley of described main hook, the two ends of the directed assembly pulley of main hook all are connected with the horizontally redirectional pulley by steel rope, be connected with balance dynamometry pulley by steel rope between two horizontally redirectional pulleys, balance dynamometry pulley is provided with force transducer, and the below of described main hook running block hangs with main hook by crossbeam.
Further improvement of the utility model is: the placement triangular in shape of jib horizontally redirectional assembly pulley, and be level intersection pulley.
The utility model compared with prior art has the following advantages: be connected with jib horizontally redirectional assembly pulley at two jib middle part changed course assembly pulleys by steel rope, jib horizontally redirectional assembly pulley is connected with jib head changed course assembly pulley by steel rope, drift angle before and after making by jib horizontally redirectional pulley like this between two places changed course roller and the steel rope reduces, and steel rope is difficult for skidding off.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: 1-main hook hoisting drum group, 2-changed course pulley, 3-jib middle part changed course pulley, 4-jib horizontally redirectional assembly pulley, 5-jib head changed course pulley, the directed assembly pulley of 6-main hook, 7-main hook running block, 8-horizontally redirectional pulley, 9-balance dynamometry pulley, 10-force transducer, 11-main hook.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show the embodiment of a kind of main lifting and winding of the utility model system as Fig. 1, described winding system comprises two main hook hoisting drum groups 1, two main hook hoisting drum groups 1 are placed side by side, two main hook hoisting drum groups 1 all are connected with changed course pulley 2 by steel rope, be connected with the steel rope that is broken line shape between two changed course pulleys 2, and each changed course pulley 2 all is connected with jib middle part changed course pulley 3 by steel rope, two jib middle part changed course pulleys 3 all are connected with one group of jib horizontally redirectional assembly pulley 4 jointly by steel rope, jib horizontally redirectional assembly pulley 4 is connected with two jib head changed course pulleys 5 by steel rope, two jib head changed course pulleys 5 move into the directed assembly pulley 6 of a main hook by steel rope and are connected with a main hook running block 7, main hook running block 7 places the bottom of the directed assembly pulley 6 of described main hook, the two ends of the directed assembly pulley 6 of main hook all are connected with horizontally redirectional pulley 8 by steel rope, be connected with balance dynamometry pulley 9 by steel rope between two horizontally redirectional pulleys 8, balance dynamometry pulley 9 is provided with force transducer 10, and the below of main hook running block 7 hangs with main hook 11 by crossbeam.Two main hook hoisting drums of the preferred described winding system of the utility model group 1, also be connected with " people " font steel rope between the two ends of changed course pulley 2,4 placements triangular in shape of jib horizontally redirectional assembly pulley, and be level intersection pulley, two jib middle part changed course assembly pulleys 3 are connected with jib horizontally redirectional assembly pulley 4 by steel rope, jib horizontally redirectional assembly pulley 4 is connected with jib head changed course assembly pulley 5 by steel rope, like this by in crane barge master lifting and winding system, reasonably having arranged one group of jib horizontally redirectional assembly pulley 4, improved large-scale floating crane master hoist rope very effectively in the excessive problem of some positions deflection angle of rope, the level intersection pulley block structure of innovation is succinct, connection and reasonable arrangement, reduced the drift angle of steel rope greatly, avoid crane barge steel rope in the process of hoisting from pulley groove, to jump out caused potential safety hazard, also prolonged the service life of steel rope simultaneously greatly.The utility model can be widely applicable for the main lifting and winding system of various large-tonnage crane barges in addition.
