Abstract
The utility model discloses a grab-bucket type floating-crane stable bucket system, which comprises a stable bucket car, a stable bucket car track, a fixed pulley, a movable pulley and a traction rope; the traction rope bypasses the fixed pulley and the movable pulley to pull the stable bucket car to move along the stable bucket car track; the movable pulley is arranged at the stable bucket car, the fixed pulley comprises a fixed pulley I and a fixed pulley II, one end of the traction rope is fixedly connected with the stable bucket car, the other end of the traction rope bypasses the fixed pulley I, the movable pulley and the fixed pulley II and then is led out; in the grab-bucket type floating-crane stable bucket system, the traction force of the stable bucket effecting on the grab-bucket is 133% of the existing art, the stable bucket effect is greatly improved, the rate of stop-work maintenance caused by the stable bucket system failures is reduced, the failures such as blocking, falling off for the stable bucket car and fracturing for the traction rope are maximumly avoided, the normal operation of the production work is ensured, the utility model is suitable for the environment with poor hydrogeological conditions, and the frequent failures and maintenance for the stable bucket system caused under the conditions of high operating speed and high operating frequency can be effectively solved.
Description
Technical field
The utility model relates to a kind of crane barge parts, particularly a kind of grab type crane barge system that surely struggles against.
Background technology
Crane barge is meant the floating platform that is loaded with hoisting crane, can move to the place of any needs in the harbour, or alongside, or moving on to the anchorage makes the goods transshipment.
Crane barge is easy to use, and weight capacity is strong.Crane barge is because its operating characteristic, and aloft amplitude of fluctuation is bigger such as the grab bucket of grab type crane barge.Thereby the system works that surely struggles against quality directly has influence on the normal operation of crane barge.Steady bucket system comprises steady trolley, steady trolley track, the fixed pulley group, running block and hauling rope, in the prior art, generally adopt two fixed pulleys to form the fixed pulley group, two movable pulleys are formed the structure of running block, after hauling rope is walked around fixed pulley and movable pulley, total four strand rope draws steady trolley, the pulling force that steady trolley acts on grab bucket is less, thereby the effect that surely struggles against is relatively poor, owing under the condition of higher operating speed and higher operation frequency, can't prevent the grab bucket rotation effectively, make that the operator can not be quick, accurate track and localization, control grab bucket step is many, material grasping, blowing is slow, can produce steady bucket dolly jam in addition, faults such as derailing need shut-down (breakdown) mainteance, influence normally carrying out of production operation, particularly, can not satisfy job requirements substantially for the higher grab type crane barge of load.
Therefore, need reduce the shut-down (breakdown) mainteance rate that causes by the steady bucket system failure, avoid faults such as steady trolley jam, derailing to greatest extent, guarantee normally carrying out of limit production operation the steady bucket system steady bucket effect that improves of existing grab type crane barge.
The utility model content
In view of this, the utility model provides a kind of grab type crane barge system that surely struggles against, and improves steady bucket effect, reduces the shut-down (breakdown) mainteance rate that is caused by the steady bucket system failure, avoid steady trolley jam to greatest extent, come off, fault such as hauling rope fracture, guarantee normally carrying out of production operation.
The grab type crane barge of the present utility model system that surely struggles against, comprise steady trolley, steady trolley track, fixed pulley, movable pulley and hauling rope, fixed pulley walked around by described hauling rope and movable pulley draws steady trolley along steady trolley orbital motion, described movable pulley is a movable pulley that is arranged on the steady trolley, fixed pulley comprises fixed pulley I and fixed pulley II, described hauling rope one end is captiveed joint with steady trolley, and the other end is drawn after walking around fixed pulley I, movable pulley and fixed pulley II successively.
Further, also comprise fixed pulley III, hauling rope is drawn through fixed pulley III;
Further, the diameter of described hauling rope is more than or equal to 13mm;
Further, the angle a between described hauling rope connection grab bucket one end and the horizontal surface is less than 40 degree.
The beneficial effects of the utility model: the grab type crane barge of the present utility model system that surely struggles against, on the steady trolley movable pulley only is set, thereby hauling rope divides 3 strands to act on the steady trolley, per share pulling force is 133% of a prior art, thereby the steady bucket pulling force that acts in the grab bucket also is 133% of prior art, improve steady bucket effect greatly, the shut-down (breakdown) mainteance rate that reduction is caused by the steady bucket system failure, avoid steady trolley jam to greatest extent, come off, faults such as hauling rope fracture, guarantee normally carrying out of production operation, be applicable to that hydrogeologic condition is poor, the harbour limited amount, the operating environment that the super original design ability of crane barge is 2 times effectively solves at high operating speed, the steady bucket system that causes under the high operation frequency condition frequently breaks down and the shut-down (breakdown) mainteance problem.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model hauling rope and grab bucket connection diagram.
The specific embodiment
Fig. 1 is the utility model structural representation, Fig. 2 is the utility model hauling rope and grab bucket connection diagram, as shown in the figure: the grab type crane barge of the present embodiment system that surely struggles against, comprise steady trolley 1, steady trolley track 2, fixed pulley, movable pulley and hauling rope 3, fixed pulley walked around successively by described hauling rope 3 and movable pulley draws steady trolley 1 along steady trolley track 2 operations, described movable pulley is a movable pulley 7 that is arranged on the steady trolley, fixed pulley comprises fixed pulley I 4 and fixed pulley II 5, described hauling rope 3 one ends are captiveed joint with steady trolley, and the other end is walked around fixed pulley I 4 successively, draw behind movable pulley 7 and the fixed pulley II 5.
After hauling rope 3 is drawn, also draw, guarantee the normal smooth operation of system, further prevent steady trolley jam, drop, prevent the hauling rope fracture through a fixed pulley III6;
In the present embodiment, the diameter of described hauling rope 3 is more than or equal to 13mm, the security of system of guaranteeing surely to struggle against, reliable and operation fast.
In the present embodiment, the angle a that described hauling rope 3 connects between grab bucket one end and the horizontal surface spends less than 40, be different from the existing 65 degree angles that make technology, it is enough big to guarantee that hauling rope 3 is used to draw the horizontal component of force of grab bucket 8 (the useful effect power of stable grab bucket), improve steady bucket effect greatly, further reduce the shut-down (breakdown) mainteance rate that causes by the steady bucket system failure, avoid steady trolley jam to greatest extent, come off, fault such as hauling rope fracture, guarantee normally carrying out of production operation.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
