Description
Technical field
The utility model belongs to coal excavation apparatus technical field, relates to a kind of rocker arm of coal mining machine, particularly relates to a kind of low seam mining machinery rocking arm adapting to the thick back timber of support.
Background technology
Low seam mining machinery is because of reliability requirement, and complete machine power is increasing, along with the increase of rocking arm cutting power, rocker arm of coal mining machine particularly housing dimensional thickness and highly also increase thereupon; Simultaneously due to the restriction of the conditions such as work plane coal seam thickness, the diameter of cylinder of low seam mining machinery type selecting is relatively little; Consider that the planted agent combining frame head and tail when adopting measures requirement again, comprehensive multiple factor, the amount of caunching of low seam mining machinery rocking arm reduces to some extent.During the too small amount of caunching, normal exploitation will be affected.
In order to solve the amount of caunching problem, owner attempts by increasing beam-ends distance, shearer ranging arm is avoided this supporting mode of support far away, but this method exists severe compromise for breaking roof, therefore this kind of mode generally can not solve the low seam mining machinery amount of the caunching mining problem caused less than normal.
For the structural configuration mode Problems existing of high-power low seam mining machinery shearer ranging arm, be badly in need of finding a kind of novel structure to solve the low seam mining machinery rocking arm amount of caunching problem.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of low seam mining machinery rocking arm adapting to the thick back timber of support, can thinning local housing, increases the rocker arm of coal mining machine amount of caunching.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Adapt to a low seam mining machinery rocking arm for the thick back timber of support, the nearly cylinder end housing in rocking arm straight-tooth chamber adopts cuts roof construction.
As a kind of preferred version of the present utility model, described rocker arm of coal mining machine comprises shearer ranging arm, motor, transmission system, cylinder; Housing comprises cuts top, incision top, circular arc platform, transition bench, closed frame.
Rocker arm of coal mining machine housing is cut top to be arranged at shearer ranging arm top and to adopt sky side away from cylinder, the formation of above cutting top increases the compliance of cylinder to thick bar timber; Being arranged at the circular arc platform cutting end face on the housing cavity of below, top, is the triangle gusset of arc transition, to connect the rib cant board of housing and to adopt sky cant board, thus cuts the bonding strength on top on increasing.
As a kind of preferred version of the present utility model, the incision top of coal machine shearer ranging arm is arranged at shearer ranging arm top and adopts sky side near cylinder, and the formation on incision top increases the compliance of cylinder to thick bar timber; Being arranged at the closed frame adopting sky cant board outer end of housing below incision top, is the rectangular cross section gusset that four limits connect between two, to increase the bonding strength of housing.
As a kind of preferred version of the present utility model, the transition bench of rocker arm of coal mining machine housing is cut top and is connected boss with the transition between incision top on being, to cut the bonding strength of the wear-resisting and housing on top and incision top on improving.
The beneficial effects of the utility model are: the low seam mining machinery rocking arm of the thick back timber of adaptation support that the utility model proposes, and realize by thinning local housing the object increasing the rocker arm of coal mining machine amount of caunching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model low seam mining machinery rocking arm.
Fig. 2 is that the AA of Fig. 1 is to sectional view.
Fig. 3 is that the BB of Fig. 1 is to sectional view.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment one
Refer to Fig. 1 to Fig. 3, the utility model discloses a kind of low seam mining machinery rocking arm adapting to the thick back timber of support, and described rocking arm 1 comprises shearer ranging arm 11, motor 12, transmission system 13, cylinder 14; Housing 11 comprises cuts top 111, incision top 112, circular arc platform 113, transition bench 114, closed frame 115.
Rocker arm of coal mining machine housing 11 is cut top 111 to be arranged at shearer ranging arm 11 top and to adopt sky side away from cylinder, the formation of above cutting top 111 increases the compliance of cylinder 14 to thick bar timber; Being arranged at the circular arc platform 113 cutting end face on housing 11 inner chamber below top 111, is the triangle gusset of arc transition, to connect the rib cant board of housing 11 and to adopt sky cant board, thus cuts the bonding strength on top 111 on increasing.
The incision top 112 of rocker arm of coal mining machine housing 11 is arranged at shearer ranging arm 11 top and adopts sky side near cylinder, and the formation on incision top 112 increases the compliance of cylinder 14 to thick bar timber; Being arranged at the closed frame 115 adopting sky cant board outer end of housing 11 below incision top 112, is the rectangular cross section gusset that four limits connect between two, to increase the bonding strength of housing 11.
The transition bench 114 of rocker arm of coal mining machine housing 11 is that the transition of above cutting between top 111 with incision top 112 is connected boss, to cut the bonding strength of top 111 and the wear-resisting and housing 11 on incision top 112 on improving.
Cut top 111 on the shearer ranging arm 11 of the utility model coal-winning machine has, compare conventional structure upper shell 111 ', can increase the amount of caunching h1, the dose-effect fruit of caunching for rich coal seam rocker arm of coal mining machine is obvious.In order to strengthen, because adopting the strength deficiency cut top 111 structure and bring, having set up circular arc platform 113 and transition bench 114 structure.
The shearer ranging arm 11 of the utility model coal-winning machine has incision top 112, compares conventional structure lower house 112 ', can increase the amount of caunching h2, and the dose-effect fruit of caunching for rich coal seam rocker arm of coal mining machine is obvious.In order to strengthen, because of the strength deficiency adopting incision top 112 structure to bring, having set up closed ore deposit 115 structure.
In sum, the low seam mining machinery rocking arm of the thick back timber of adaptation support that the utility model proposes, realizes by thinning local housing the object increasing the rocker arm of coal mining machine amount of caunching.
Here description of the present utility model and application is illustrative, not wants by scope restriction of the present utility model in the above-described embodiments.Distortion and the change of embodiment disclosed are here possible, are known for the replacement of embodiment those those of ordinary skill in the art and the various parts of equivalence.Those skilled in the art are noted that when not departing from spirit of the present utility model or substantive characteristics, the utility model can in other forms, structure, layout, ratio, and to realize with other assembly, material and parts.When not departing from the utility model scope and spirit, can other distortion be carried out here to disclosed embodiment and change.
