Abstract
The utility model discloses an electric double-toothed-bar start-stop machine. According to the technical scheme, the electric double-toothed-bar start-stop machine comprises shells, driving gear sets in the shells and toothed bars matched with the gear sets, wherein the shells comprise a shell I and a shell II which have the same structure; a hand-cranking mechanism is connected with a speed reducer; an output shaft of the speed reducer is connected with a power input shaft of the driving gear set in the shell I; and the other end of the power input shaft in the shell I penetrates through the shell I and is connected with a power input shaft of the driving gear set in the shell II through a coupler. The electric double-toothed-bar start-stop machine has the advantages that the machine has a compact structure and a large span and is high in synchronicity, stably started and stopped, high in start-stop force and high in overload resistance, and a gate cannot be inclined in the start-stop process.
Description
Technical field
The utility model is a kind of electrodynamic type bidentate bar headstock gear.
Background technology
In hydraulic structure, the lifting appliance that is used for operating equipment such as gate, trashrack becomes headstock gear.According to the operation needs of water power industry, headstock gear is being undertaken the regulating gate water yield, is being drained off floodwater, arranging vital tasks such as husky sand surfing, and simultaneously, headstock gear also can be accomplished back works such as installation and the maintenance of other metal constructions and electromechanical equipment.Have following characteristics during headstock gear work: 1) the drive gate is done along the lock groove and is moved up and down or make gate around a hinge rotation; The load of gate action this moment on headstock gear not only depends on the weight of gate movable part; The frictional resistance that also depends on antipriming and walking support device to a great extent, and silt alluvial, various floating thing, lock groove embedded part running resistance such as freeze; In addition, the headstock gear of operation gate in moving water, the size of load is also relevant with the flowing pressure that changes with gatage.Also have a kind of special circumstances; When gate is closed the aperture by deadweight with door top water column weight; The power that acts on the headstock gear lifting mechanism possibly be zero, thereby can cause the flexible member that connects gate and headstock gear, as: the relaxing of wire rope, chain, more piece suspension rod etc.; Gate is broken off relations, will fierce impact take place because of falling of gate.This shows that the load change of headstock gear in the operation engineering is very uneven, load might substantially exceed rated value.2) many gates need two suspension centres to open and close, and must guarantee that at this moment two suspension centres are synchronized with the movement, otherwise can cause that gate is crooked, possibly cause headstock gear to transship or damages such as the antipriming of gate, walking support device.3) operating rate of headstock gear is very low (generally is no more than 4m/min, has only the decrease speed of some stop gate headstock gear can reach 10～14m/min) sometimes.
The kind of drive of headstock gear has machine driving and two kinds of forms of hydraulic drive, and wherein machine driving has patterns such as winding type, screw, chain.Winding type adopts the wire rope pattern to be mostly two suspension centres, and structure is complicated, is prone to break off relations, and can not apply a power of closing, manual adjustments difficulty etc.; The screw transmission efficiency is low, easy to wear, it is high-power to be difficult to make, and two suspension centres need increase drive link, and complex structure and effect are unstable, and two cover mechanisms are used in manual operation, the people around the time difficulty synchronously, be prone to stuck; Chain type exists and the similar shortcoming of winding type.Though the fluid pressure type stable drive, need take measures when complex structure, two suspension centre is that oil pressure is identical in two hydraulic cylinders, and when gatage was big, piston rod can be very long, processing difficulties, and cost is high, and the Hydraulic Elements sealing is leaked easily in addition.All there is more defective in above-mentioned technology.
Summary of the invention
The utility model provides a kind of compact conformation to the deficiency of prior art, and synchronism is good, and span is big, and gate can run-off the straight during keying, opens and closes steadily, and hoisting capacity is big, the technical scheme of the electrodynamic type bidentate bar headstock gear that anti-overload ability is strong.
The utility model is realized through following technical measures: a kind of electrodynamic type bidentate bar headstock gear; Comprise drive gear set in casing and the casing and the ratch that cooperates with gear train; Said casing comprises casing one, casing two; Structure in casing one and the casing two is identical; Have motor output shaft to be connected with reductor, the power input shaft of drive gear set is connected in said reductor shaft and the casing one, and the other end of the power input shaft in the said casing one passes the power input shaft of casing one through the interior drive gear set of shaft coupling and casing two and is connected.
The concrete characteristics of the utility model also have, and also have the jaw opening sensor that aperture shows on the said machine casing two.
The beneficial effect of the utility model is: compact conformation, and synchronism is good, and span is big, and gate can run-off the straight during keying, opens and closes steadily, and hoisting capacity is big, the electrodynamic type bidentate bar headstock gear that anti-overload ability is strong.

Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1, motor, 2, ratch, 3, reductor, 4, shaft coupling, 5, casing one, 6, casing two, 7, jaw opening sensor, 8, power input shaft, 9, power input shaft, 10, gate.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
Shown in accompanying drawing; A kind of electrodynamic type bidentate bar headstock gear; Comprise drive gear set in casing and the casing and the ratch 2 that cooperates with gear train; Said casing comprises casing 1, casing 26, and the structure in casing 1 and the casing 26 is identical, has motor 1 output shaft 1 to be connected with reductor 3; The power input shaft 8 of drive gear set is connected in said reductor 3 shafts and the casing one, and the other end of the power input shaft 8 in the said casing one passes the power input shaft 9 of casing one through the interior drive gear set of shaft coupling 4 and casing 26 and is connected.Also have the jaw opening sensor 7 that aperture shows on the casing 26.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
