Abstract
The utility model relates to a rotating device driven by electricity or hands, which is designed to satisfy the requirements of the SOLAS1983 amendment and the CCS1992 ship legal inspection technical regulation and is composed of an electric motor, a rocking handle, an outer meshing gear transmission pair, a worm wheel transmission pair, and an inner meshing gear transmission pair. The whole transmission mechanism is contained in a barrel body which is used as the base of the rotating device, and the utility model has the advantages of compact structure, favorable barrel property for sea waves, wind and rain, large transmission rate, reasonable distribution, convenient manufacture and maintenance, etc. The utility model is suitable for being used as a rotating device for hangers for rescue crafts, hangers for life rafts, and supply hangers for ships.
Description
The utility model relates to the turning gear that a kind of boats and ships life and boats and ships supply are hung, particularly a kind of turning gear of single armed ship raft suspension bracket.
As the life of boats and ships, must meet existing international and domestic relevant specification, i.e. SOLAS1983 amendment and CCS1992 Technical Regulation for Statutory Survey of Seagoing Ships.At least should satisfy following 2 requirements for turning gear: 1. boats and ships are under the bad working environments of 10 ° of trims and 20 ° of heels, work effectively, for the rescue craft suspension bracket, more require under this operating mode, the rescue craft that can will be fully loaded with the member produces to outboard smoothly apace from deposit position; 2. must possess manual unit, under the situation of boats and ships dead electricity, still can work effectively guaranteeing.At present domestic manual swinging rescue craft suspension bracket and the manual swinging liferaft suspension bracket of only producing simple function, its turning gear running part is arranged in the pedestal outside more, and shared locus is bigger, also is unfavorable for the protection to stormy waves.The high-mobility, multipurpose, wheeled vehicle suspension bracket is abroad arranged, promptly have the rescue craft suspension bracket concurrently, the function that the three is hung in liferaft suspension bracket and supply, its turning gear all adopts " hydraulic pressure/manual " to drive, owing to have manual emergency facility, can satisfy the requirement about still effectively working under the dead electricity situation in the standard, under the situation of dead electricity not, adopt power driven, improve work efficiency, improved crewman's labor condition, but there has been complex structure in fluid pressure drive device, cost is higher, safeguards inconvenient shortcoming.
The purpose of this utility model is to provide a kind of code requirement that meets, and it is simple, easy to maintenance to make processing, and low price is applicable to the turning gear of high-mobility, multipurpose, wheeled vehicle suspension bracket.
The utility model is realized by following technical proposals.
Turning gear by electrical motor, jiggle bar, interior external meshing tooth transmission pay, worm drive is paid and the pedestal cylindrical shell is formed.Electrical motor 2 by coupling sleeve 3 and external meshing tooth transmission pay 4 and 5, worm drive pays 6 and 7, internal gearing is paid 9 and 10 and connected, gear 10 is the internally toothed annulus on the pivoting support 14, the two ends projecting shaft of worm screw 6 all has square end, jiggle bar 11 can be enclosed within on the square end, and all transmission devices all are contained in the cylinder 1 as the device pedestal.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the turning gear transmission diagram.
Fig. 2 is the turning gear constructional drawing.
Fig. 3 is a turning gear A-A section-drawing.
Fig. 4 is a turning gear B-B section-drawing.
Turning gear is made up of pivoting support 14, the jiggle bar 11 of pedestal cylindrical shell 1, electrical motor 2, coupling sleeve 3, gear 4, gear 5, worm screw 6, worm gear 7, worm-wheel shaft 8, gear 9, band inner gear 10, and whole drivings device are installed in the cylinder 1 as the device pedestal.Be provided with two bearing back plates 12 and a dividing plate 13 in the pedestal cylindrical shell 1, cylindrical shell is divided into three parts, one is the oil bath C of level gear pair at a high speed, and it two is oil bath D of middling speed level worm gear pairs, and third part is connection box, cable lead-through E.The two ends projecting shaft of worm screw 6 all has square end, puts jiggle bar 11 and gets final product M/C.Electrical motor 2 is the flange form motor, and the motor flange dish can seal the pedestal cylindrical shell.Electrical motor 2 is not established drg, so that driven by shaking, utilizes the self-locking action of worm and gear, makes revolution arm location.But level gear pair oil bath C and middling speed level worm gear pairs oil bath D are respectively equipped with oil ga(u)ge window, drain tap and gas filed observation window at a high speed.The supporting of various transmission shafts is coro bearng, and the engagement big gear wheel is the internally toothed annulus on single 4 the contact pivoting supports 14 of universal component in the afterbody.
The turning gear type of drive is:
1. when electronic: pivoting support 14 → arm revolution of electrical motor 2 → coupling sleeve 3 → gear 4 → gear 5 → worm screw 6 → worm gear 7 → gear 9 → band internally toothed annulus.
2. when manual: pivoting support 14 → arm revolution of jiggle bar 11 → worm screw 6 → worm gear 7 → gear 9 → band internally toothed annulus 10.
Electric transmission divides three grades, level external meshing tooth transmission at a high speed, and the middling speed level is a worm drive, low speed turbine stage is interior engages spur gears transmission.Cancellation level transmission at a high speed is manual transmission, under the dead electricity situation, as required, can 1～2 people operate at pedestal one or both sides jiggle bar, and the supporting mass of handle is a cylindrical shell, and supporting is stable, is convenient to firmly.This device transmitting ratio is big, distributes rationally.
Manually with electronic between the electric protection interlocking is arranged, inserting behind the handle just can not energized, does not promptly exist to drive handle when electronic and rotate the danger of hurting sb.'s feelings.
The whole transmission devices of the utility model are contained in the cylinder as equipment base, has compact conformation, take the little characteristics in position, deck, help the reasonable Arrangement of life boat and liferaft on the ship deck and avoid the invasion and attack of wave wind and rain, compare with hydraulically powered turning gear that to have the processing of manufacturing simple, easy to maintenance, advantages such as low price.
The utility model can be used as the turning gear of boats and ships single armed life boat, liferaft suspension bracket, also can be used as the similar boats and ships supply crane of workload turning gear.If with its electronic partial cancellation, can make the usefulness of manual turning gear.
