Description
Technical field
The utility model relates to the safety installations that uses on a kind of single cylinder diesel, anti-reverse safe starter during the starting of particularly a kind of single cylinder diesel.
Background technique
As everyone knows, single cylinder diesel such as SF120, SF140 etc., generally by the operating crank hand starting, the single cylinder diesel cylinder diameter is increasing in recent years, has increased the starting resistance of single cylinder diesel relatively.When hand single cylinder diesel starts, because the torsion deficiency very easily causes the starting of catching fire of reversing, both by the silencing apparatus air inlet, the air-strainer exhaust.Single cylinder diesel is under the inverted status, and operating crank is difficult for separating with starting dog, and with the single cylinder diesel backward rotation, in this case, personnel's arm of operation sheet cylinder diesel is very easily injured by operating crank, causes the person or equipment injury accident.In order to improve the single cylinder diesel Safety performance, injury operator's accident takes place when preventing the single cylinder diesel counter-rotating, and country has issued the hand safe starting pressure of single cylinder diesel standard specially.For this reason, many manufacturers and knowledgeable people abide by NBS and require to develop and study, manufacture experimently out various single cylinder diesel anti-reversal starting devices, though anti-reversal starting device complies with the national standard requirements basically, but also exist deficiencies such as complex structure, anti-reverse separation is unreliable, cost of production is high, using effect is undesirable, the Consumer is difficult to accept.
Summary of the invention
For overcoming the deficiency that existing single cylinder diesel anti-reversal starting device exists, the purpose of this utility model provides a kind ofly can meet the state compulsion standard-required, can satisfy the single cylinder diesel anti-reversal starting device of user's needs again.
The technological scheme that its technical problem that solves the utility model adopts, it comprises operating crank, guide pin bushing, with the AO actuating sleeve of starting and be fixed on fixed cover on the single cylinder diesel starting seat, the tail end of described actuating sleeve is arranged on the step axis hole of guide pin bushing, operating crank is movably arranged in the guide pin bushing, the corresponding end face tooth of operating crank and actuating sleeve embedding engagement, between operating crank and guide pin bushing, be provided with and operating crank separated or the separating mechanism of combination with actuating sleeve, between guide pin bushing and fixed cover, be provided with unidirectional rotating machinery.
For operating crank is separated or with actuating sleeve in conjunction with reliable, described separating mechanism comprises and is fixed on the pilot pin on the operating crank and is arranged on guide groove on the guide pin bushing, pilot pin and guide groove Spielpassung, pilot pin can drive operating crank reach or retraction under the guiding of guide groove.
In order to make the operating crank can only one-way rotation, described unidirectional rotating machinery comprises single direction ratchet and at least one group of elasticity backing pin that is arranged on the guide pin bushing end face, the elasticity backing pin is made up of backing pin and spring and is arranged on the end face circumference of fixed cover, the elasticity backing pin can freely stretch on fixed cover, and backing pin cooperates with single direction ratchet is unidirectional.
In order to make tooth embedding engagement fit reliable, described tooth embedding engagement is yi word pattern or cross cooperation.
For pilot pin is moved flexibly in guide groove, the guide groove on the described guide pin bushing is skewed slot or bias groove or curve bath.
In order to prevent actuating sleeve play on the step axis hole of guide pin bushing, described actuating sleeve is provided with the jump ring that prevents axial float.
After adopting said structure, operating crank and the embedding of actuating sleeve tooth engagement during normal starting, actuating sleeve drives starting shaft starting single cylinder diesel; When single cylinder diesel reversed, because the ratchet on the guide pin bushing can not reverse guide pin bushing with unidirectional cooperation of the backing pin on the fixed cover, the guide groove of operating crank on the guide pin bushing of pilot pin effect lower edge bounced back and separates fast with actuating sleeve; Have simple and compact for structure, starting and separate advantages such as fast and flexible, long service life, cost of production are low.

Embodiment
Fig. 1, Fig. 2 and shown in Figure 3, specific embodiments for a kind of single cylinder diesel anti-reversal starting device of the utility model, it comprises operating crank 1, guide pin bushing 2, be fixed on fixed cover 6 on the single cylinder diesel starting seat 12 with the actuating sleeve 7 of starting shaft 11 interlocks and by screw 4, the tail end of described actuating sleeve 7 is arranged on the step axis hole of guide pin bushing 2, actuating sleeve 7 is provided with the jump ring 8 that prevents axial float, operating crank 1 is movably arranged in the guide pin bushing 2, operating crank 1 and actuating sleeve 7 corresponding end face tooth embedding engagements, tooth embedding engagement can be yi word pattern or cross or alternate manner.
Between operating crank 1 and guide pin bushing 2, be provided with and operating crank 1 separated or the separating mechanism of combination with actuating sleeve 7, this separating mechanism comprises the pilot pin 3 that is fixed on the operating crank 1 and is arranged on guide groove 21 on the guide pin bushing 2, pilot pin 3 and guide groove 21 Spielpassung, pilot pin 3 can drive operating crank 1 reach or retraction under the guiding of guide groove 21, guide groove 21 can be skewed slot or bias groove or curve bath.
Between guide pin bushing 2 and fixed cover 6, be provided with unidirectional rotating machinery, this unidirectional rotating machinery comprises single direction ratchet 22 and the three groups of elasticity backing pins that are arranged on guide pin bushing 2 end faces, the elasticity backing pin is made up of backing pin 5 and spring 10, and be arranged on by screw 9 on the end face circumference of fixed cover 6, backing pin 5 can freely stretch in fixed cover 6 under the effect of spring 10, backing pin 5 and 22 unidirectional cooperations of single direction ratchet.
During normal starting, fixed cover 6 is fixed on the single cylinder diesel starting seat 12, actuating sleeve 7 and starting shaft 11 interlocks, rotate operating crank 1, the pilot pin 3 that is fixed on the operating crank 1 moves forward along the guide groove on the guide pin bushing 2 21, operating crank 1 is also with pilot pin 3 reaches and actuating sleeve 7 tooth embeddings engagement, because single direction ratchet 22 backing pin 5 rotations relatively during normal starting, backing pin 5 is inoperative, and starting shaft 11 drives the starting single cylinder diesel at actuating sleeve 7.
When single cylinder diesel reverses, starting shaft 11 drives operating crank 1 counter-rotating by actuating sleeve 7, because backing pin 5 can not reverse guide pin bushing 2 with 22 unidirectional cooperations of single direction ratchet, guide groove 21 retractions of operating crank 1 on pilot pin 3 effect lower edge guide pin bushings 2, operating crank 1 separates fast with actuating sleeve 7 tooth embeddings engagement, actuating sleeve 7 oppositely dallies, thereby avoids the generation of single cylinder diesel when starting counter-rotating casualty accident effectively.
