Description
Technical field
The utility model relates to technical field of crane equipment, is specifically related to a kind of restriction gear mechanism of master controller for crane.
Background technology
Master controller is widely used in crane tool electric control system, belong to electric control system core, a lot of master controller is when design, maximum gear has five grades or six grades, but when user specifically uses, not necessarily will use maximum gear, such as some only needs to use third gear or fourth gear.Therefore, in order to the demand of satisfied different client, just need to add one in addition for limiting the mechanism of maximum gear, be called for short limit gear mechanism, the complicated structure of current limit gear mechanism, intensity is little, easily problem occurs during use.
Utility model content
The utility model provides a kind of and limits gear mechanism, solves the complicated structure of master controller limit gear mechanism in prior art, the problem that intensity is little.
The utility model realizes the technical scheme that above-mentioned technique effect adopts:
A kind of restriction gear mechanism, comprise frame, speed changer gear operation system, spacer and bracket component, described speed changer gear operation system and bracket component are arranged in frame, described spacer is arranged in speed changer gear operation system, described spacer comprises stiff end and positioning end, described stiff end is provided with some fixing holes, a catch is all extended in the end, two ends of described positioning end, described bracket component is fixedly connected with limited shelves pin, described limit shelves pin is between two catch, after operation speed changer gear operation system reaches the maximum gear of needs, then described catch is stuck on limit shelves pin.
Further, described speed changer gear operation system comprises action bars and sector gear, and described action bars is connected with sector gear by semiaxis, and described spacer is fixedly connected on the outside side wall of sector gear.
Further, described catch and spacer are integrative-structures.
Further, described limit shelves pin is fixed on bracket component by welding manner.
The beneficial effects of the utility model are: the utility model has that structure is simple, easy to use, structural strength is good and the advantage of accurate positioning, only need add keeper can realize limitting shelves function with limit shelves pin, if in use need change the gear of restriction simultaneously, only need pull down original keeper, the keeper needed is selected to install again, secondly keeper adopts quality steel plate to be once stamped to form, sturdy and durable.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
As Figure 1-3, a kind of restriction gear mechanism, comprise frame 1, speed changer gear operation system 2, spacer 3 and bracket component 4, described speed changer gear operation system 2 and bracket component 4 are arranged in frame 1, described spacer 3 is arranged in speed changer gear operation system 2, described speed changer gear operation system 2 comprises action bars 21 and sector gear 22, and described action bars 21 is connected with sector gear 22 by semiaxis 23, and described spacer 3 is fixedly connected on the outside side wall of sector gear 22.The shape of described spacer 3 and the mating shapes of sector gear 22.Described spacer 3 comprises stiff end 31 and positioning end 32, and described stiff end 31 is provided with some fixing holes 311, and a catch 321 is all extended in the end, two ends of described positioning end 32, and described catch 321 is integrative-structures with spacer 3.Described bracket component 4 is fixedly connected with limited shelves pin 41, and described limit shelves pin 41 is fixed on bracket component 4 by welding manner.Described limit shelves pin 41 is between two catch 321, and after operation speed changer gear operation system 2 reaches the maximum gear of needs, then described catch 321 is stuck on limit shelves pin 41.
During work, operation action bars 21 moves, action bars 21 drives semiaxis 23 to rotate, the sector gear 22 of semiaxis 23 end rotates together along with semiaxis 23, different gear is reached by the weave control master controller of sector gear 22, form whole speed changer gear operation structure, the utility model has been fixedly connected with spacer 3 on the outside side wall of sector gear 22, bracket component 4 is provided with accordingly in frame, when operating action bars, spacer 3 and sector gear 22 are synchronized with the movement, when reaching default maximum gear in motion process, the catch 321 of spacer 3 end can be stuck on the limit shelves pin 41 on bracket component 4, reach the object limiting gear, the catch at the two ends of keeper is according to gear accurate Calculation, with the needs of the various gear of satisfied restriction.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
