At present, capstan winch kind is a lot, and its power transmission form has multiple: as motor-driven, pneumatic, electronic, hydraulic pressure etc., no matter the composition such as all dynamic source of capstan winch of which kind of type of belt drive, control mechanism, retarder, power-transfer clutch, roller stand and annex;
In addition, capstan winch can be divided into common drop-gear box capstan winch, planet wheel capstan, worm and gear capstan winch, cycloidal-pin wheel capstan winch etc. according to retarder kind, wherein with satellite gear and worm and gear capstan winch in the majority, cross-country rescue can be widely used in, engineering rescue, military transportation, mining industry, woods herd fishery etc.; And worm and gear capstan winch has its original transmission latching characteristics because of it among this, thus make it in operation use procedure, have original safe and reliable advantage;
But the power-transfer clutch of existing worm and gear capstan winch, for many years adopt shift fork slide block clutch form for a long time in the world, disclosed in Chinese patent ZL201120546171.6 a kind of " small-sized hydraulic capstan winch manual clutch ", its power-transfer clutch faying face is few and little, thus cause contact strength low, clutch block is located loosely, easily produces clutch off-gear phenomenon, cause extraordinarily serious safety accident; Meanwhile, as long as owing to engaging two breach between slide block with reel, so reel must rotate 180 degree just once engage chance, cause this clutch operating difficulty, minimumly during winching operations want two people operation; The operating difficulties of shift fork, and be difficult to realize air clutch, simultaneously under conventional structure form, realize air clutch needs additionally to add a cylinder, thus adds the difficulty of installing and fixing and handling, and cost is very high; The power-transfer clutch productive costs of this kind of shift fork form is high in addition.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple to operate, with low cost and safe and reliable worm and gear winch clutching device structure.
The purpose of this utility model is achieved in that
A kind of worm and gear pneumatic clutch structure, described structure includes the reel be set up on capstan winch support, capstan winch support is divided into two supports in left and right, the two ends of reel are set up on two supports in left and right respectively, clutch rod and transmission shaft is plugged with in described reel, the left socle of described capstan winch support is provided with cylinder body, clutch rod left end inserts on the one end in this cylinder body cavity and is set with piston, described transmission shaft is equipped with a clutch spline housing by key adapter sleeve, this clutch spline housing is connected with key between mandrel interior wall, and clutch spline housing is connected with the right-hand member of clutch rod.
A kind of worm and gear pneumatic clutch of the utility model structure, described clutch rod is set with retracing spring, and this retracing spring one end is placed on the left socle of capstan winch support, and the other end is placed on clutch rod.
A kind of worm and gear pneumatic clutch of the utility model structure, described transmission shaft is provided with male splines, and clutch spline housing is set on this male splines, and the inner tube wall of described reel is provided with female splines, and clutch spline housing is inserted in this female splines) in.
A kind of worm and gear pneumatic clutch of the utility model structure, the central axis of described clutch rod and transmission shaft is located along the same line.
Compared with prior art, the beneficial effects of the utility model are:
Power-transfer clutch shown in the utility model, adopts spline drived form by clutch spline housing and reel, makes to engage probability during clutch control and increases substantially; Spline drived substantially increases power-transfer clutch loading strength simultaneously; Secondly by retracing spring, automatic engagement is achieved; Make clutch control comfort simple; The requirement that the processing request of new construction can not show a candle to old structure is high, and difficulty of processing reduces, and tooling cost reduces greatly; Meanwhile, after new construction adopts pneumatic form, structure is simple, processing installation is all very convenient and with low cost.

Detailed description of the invention
See Fig. 1, a kind of worm and gear pneumatic clutch structure that the utility model relates to, described structure includes the reel 6 be set up on capstan winch support 7, concretely, capstan winch support 7 is divided into two supports in left and right, the two ends of reel 6 are set up on two supports in left and right respectively, clutch rod 2 and transmission shaft 5 is plugged with in described reel 6, and the central axis of clutch rod 2 and transmission shaft 5 is located along the same line, the left socle of described capstan winch support 7 is provided with cylinder body 1, clutch rod 2 left end inserts on the one end in this cylinder body 1 cavity and is set with piston 8, thus make when passing into high pressure gas on the right side of cylinder body 1 inner carrier, piston is translation left, drive clutch rod 2 to left, and clutch rod 2 is set with retracing spring 3, this retracing spring 3 one end is placed on the left socle of capstan winch support 7, the other end is placed on clutch rod 2, described transmission shaft 5 is equipped with a clutch spline housing 4 by key adapter sleeve, between this clutch spline housing 4 with reel 6 inwall, key is connected, and clutch spline housing 4 is connected with the right-hand member snap-fit engagement of clutch rod 2,
Concretely, described transmission shaft 5 is provided with male splines a, and clutch spline housing 4 is set on this male splines a, and the inner tube wall of described reel 6 is provided with female splines b, and clutch spline housing 4 is inserted in this female splines b;
The right-hand member of described clutch rod 2 is movably installed with a snap ring, and (this snap ring can rotate around the central axis of clutch rod 2, but can not along the centerline axis parallel of clutch rod 2), the left side of described clutch spline housing is connected with above-mentioned snap ring, thus make clutch rod 2 parallelly can pull clutch spline housing 4, and when clutch spline housing 4 works, when transmission shaft 5 drives reel 6 to rotate, clutch rod 2 can not be subject to the impact of now rotational force.
Principle of work of the present utility model is: when passing into high pressure gas on the right side of cylinder body 1 inner carrier, the thrust produced by piston 8 overcomes the spring force of retracing spring 3, thus pull clutch rod 2, clutch spline housing 4 is slided along male splines a on transmission shaft 5, when clutch spline housing 4 skids off the female splines b engaged with reel 6, reel 6 is separated with transmission shaft 5, achieves winch clutching and throws off; When capstan winch needs twisted rope operation, the high pressure gas in reverse operating cylinder body 1, make clutch spline housing 4 under retracing spring 3 spring-force driven dual, can automatically reset to engagement with clutch rod 2.
In addition: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.
