Abstract
The utility model relates to a rake lifting device and discloses an emergency rake lifting device. The emergency rake lifting device comprises a rake lifting crane, guide wheels and a rake arm, a hanger rope is guided out of the rake lifting crane, is wound around the guide wheels and then is connected on the rake arm, the rake lifting crane comprises a winch, a working motor and a stand-by motor, the winch is used for winding up and paying off the hanger rope, the working motor is coaxially connected with the winch, and a rotary shaft of the stand-by motor is in transmission connection with a rotary shaft of the winch. The emergency rake lifting device further comprises a clutch, and the rotary shaft of the stand-by motor is connected with the rotary shaft of the winch through the clutch. On the basis that the working motor is used as the power of the rake lifting crane, the stand-by motor is added for meeting an emergency, and the emergency rake lifting device is simple in structure and high in safety and reliability.
Description
Technical field
The utility model relates to a kind of rake device, relates in particular to a kind of dredge boat with having met an urgent need rake device.
Background technology
The hydraulic pressure that the rake arm of existing dredge boat is connected to hull by drag-line rises on rake crane, but under specific circumstances, if drag head hydraulic pressure plays rake crane, hydraulic system breaks down, drive the work motor of capstan winch to quit work, rake arm cannot be sling, under this rugged environment in ocean, if rake arm cannot be sling, may bring unpredictable infringement or potential safety hazard.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is the problem that rake arm cannot be packed up after the work motor that how to solve existing rake device breaks down.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of rake device of having met an urgent need, it has comprised rake crane, guide wheel and rake arm, hanger rope from rake crane draw and be connected to around guide wheel rake arm on, described rake crane comprises capstan winch, work motor and standby motor, described capstan winch is for folding and unfolding hanger rope, and described work motor is coaxially connected with capstan winch, and the rotating shaft of described standby motor is connected with the rotating shaft transmission of capstan winch.
Further, also comprise clutch, the rotating shaft of described standby motor is connected with the rotating shaft of capstan winch by clutch.
Further, described work motor is hydraulic motor.
Further, described standby motor is electro-motor.
(3) beneficial effect
A kind of rake device of having met an urgent need that the utility model provides, usings on the basis of work motor as power at a rake crane, has increased standby motor to make emergency, and it is simple in structure, safety and reliability is high.
Accompanying drawing explanation
Fig. 1 is the utility model mounting structure schematic diagram of cake device on dredge boat of having met an urgent need;
Fig. 2 is the structural representation that the utility model plays cake crane.
In figure: 1, hull; 2, play rake crane; 3, guide wheel; 4, hanger rope; 5, rake arm; 6, capstan winch; 7, work motor; 8, standby motor; 9, clutch.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be mechanical connection, can be to be also electrically connected to; Can be to be directly connected, also can indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
As depicted in figs. 1 and 2, a kind of rake device of having met an urgent need of the utility model, it has comprised rake crane 2, guide wheel 3 and rake arm 5, hanger rope 4 from rake crane 2 draw and be connected to around guide wheel 3 rake arm 5 on, play rake crane 2 and comprise capstan winch 6, work motor 7 and standby motor 8, capstan winch 6 is for folding and unfolding hanger rope 4, and work motor 7 is coaxially connected with capstan winch 6, and the rotating shaft of standby motor 8 is connected with the rotating shaft transmission of capstan winch 6.Standby motor 8 rotates and can drive capstan winch 6 to rotate together.
In order to have improved the stability of rake operation, this rake device of having met an urgent need also comprises clutch 9, and the rotating shaft of standby motor 8 is connected with the rotating shaft of capstan winch 6 by clutch 9.
Wherein, work motor 7 is hydraulic motor; Standby motor 8 is electro-motor.
A kind of rake device of having met an urgent need that technique scheme provides, be applied in dredge boat, its process is: rake crane 2 and guide wheel 3 have been installed on the deck of hull 1, hanger rope 4 is drawn and is connected to after guide wheel 3 on rake arm 5 through playing the capstan winch 6 of rake crane 2, to realize lifting rake arm 5, rake arm 5 band moving-targets are first with lifting; Play rake crane 2 under normal operation condition, by work motor 7 lifting drag heads and rake arm 5, under specific circumstances, if work motor 7 breaks down, can be by having started the standby motor 8 on rake crane 2, and the clutch 9 that closes, power by standby motor 8 drives capstan winch 6 to rotate, and then lifting drag head and rake arm 5, avoid work motor 7 to break down and drag head and rake arm 5 cannot be lifted by crane, and cause device damage or bring potential safety hazard.
In sum, the rake device of having met an urgent need of the present utility model, usings on the basis of work motor 7 as power at a rake crane 2, has increased standby motor 8 to make emergency, and it is simple in structure, safety and reliability is high.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
