Abstract
The utility model provides an oscillating type toothed bar start-stop machine. The machine comprises a shell, a driving gear set in the shell and a toothed bar matched with the driving gear set, wherein the toothed bar penetrates through the shell; the lower end of the toothed bar is connected with an arc-shaped gate in a movable mode; the lower end of the shell is connected with a shell seat in a movable mode; a speed reducer is arranged on the outer side of the shell; a power output end of the speed reducer is connected with a power input end of the driving gear set in the shell; a power input end of the speed reducer is connected with a damper; a power input end of the damper is connected with a clutch; and a power input end of the clutch is connected with a driving device. According to the start-stop machine, the shell can swing around the shell seat, so that the arc-shaped gate has a large start-stop angle; and in addition, the toothed bar is directly connected with the arc-shaped gate without a middle connecting piece, so that the whole machine has a simple and compact structure, and is high in synchronicity, stably started and stopped, high in start-stop force and low in cost.
Description
Technical field
The utility model relates to a kind of headstock gear, especially a kind of swing type ratch headstock gear.
Background technology
Headstock gear is the lifting appliance that is used for operating equipment such as gate, trashrack.According to the operation needs of water power industry, headstock gear is being undertaken vital tasks such as the husky sand surfing of the regulating gate water yield, flood discharge, row, and simultaneously, headstock gear also can be accomplished back works such as installation and the maintenance of other metal constructions and electromechanical equipment.
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, is 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.Existing in prior technology weak point that Here it is.
Summary of the invention
The technical problem that the utility model will solve is exactly not enough to existing in prior technology, and provides a kind of simple in structure, compact, and synchronism is good, opens and closes steadily, and hoisting capacity is big, and the low swing type ratch headstock gear of cost.
This programme is realized through following technical measures: this swing type ratch headstock gear comprises drive gear set in casing and the casing and the ratch that cooperates with drive gear set; Said ratch passes casing; The lower end of ratch and Segment gate flexibly connect, and the casing lower end is connected with chassis block, and the casing arranged outside has reducer; The clutch end of reducer links to each other with the power intake of drive gear set in the casing; The power intake of reducer is connected with damper, and the power intake of damper is connected with clutch, and the power intake of clutch is connected with drive unit.
The said machine casing outside also is provided with jaw opening sensor, and the aperture that is used for Segment gate shows.
Above-mentioned drive unit is hand-operated mechanism or the motor that has handwheel, can select flexibly according to concrete needs.
The beneficial effect of this programme can be learnt according to the narration to such scheme; In this swing type ratch headstock gear, said ratch passes casing, and the lower end of ratch and Segment gate flexibly connect; The casing lower end is connected with chassis block; The casing arranged outside has reducer, and the clutch end of reducer links to each other with the power intake of drive gear set in the casing, and the power intake of reducer is connected with damper; The power intake of damper is connected with clutch, and the power intake of clutch is connected with drive unit.In this headstock gear, housing part can be swung around chassis block, makes Segment gate have bigger keying angle, in addition; Ratch directly links to each other with Segment gate, does not need intermediate connector, makes complete machine structure simple, compact, and synchronism is good; Open and close steadily, hoisting capacity is big, and cost is low.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the user mode sketch map of the utility model specific embodiment.
Among the figure, 1 is reducer, and 2 is damper, and 3 is clutch, and 4 is hand-operated mechanism, and 5 is handwheel, and 6 is motor, and 7 is chassis block, and 8 is ratch, and 9 is casing, and 10 is jaw opening sensor, and 11 is Segment gate.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below through the specific embodiment, and combine its accompanying drawing, this programme is set forth.
A kind of swing type ratch headstock gear, as depicted in figs. 1 and 2, it comprises that casing 9 and casing 9 interior drive gear set reach the ratch 8 that cooperates with drive gear set; Said ratch 8 passes casing 9; The lower end of ratch 8 and Segment gate 11 flexibly connect (as hinged), and casing 9 arranged outside have jaw opening sensor 10, and casing 9 lower ends flexible connections (as hinged) have chassis block 7; Casing 9 outsides also are provided with reducer 1; The clutch end of reducer 1 links to each other with the power intake of drive gear set in the casing 9, and the power intake of reducer 1 is connected with damper 2, and the power intake of damper 2 is connected with clutch 3; The power intake of clutch 3 is connected with drive unit, and this drive unit can adopt hand-operated mechanism 4 or the motor 6 that has handwheel 5.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model, repeat no more at this.
