Description
Technical field
The utility model relates to mine technology field, relates in particular to a kind of rail mining car.
Background technology
In the mining operations in colliery, adopt modal inclined gallery transportation mode while winching mine car along orbital motion, for the large problem of mine car generation derailing accident harmfulness, adopt the safety facilities such as arrester to tackle the mine car that sport car occurs.Current arrester device likely the mine car load carrying ability that sport car occurs compared with large, impacted strong and was destroyed, and cause its inefficacy, cannot make mine stop, finally cause the generation of the accident such as device damage, personal casualty.For above-mentioned deficiency, existing arrester device is carried out to the improved while, also self structure is improved, even if make it in the situation that arrester lost efficacy, still automatically starting emergency brake device, avoids accident harm further to expand.Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of rail mining car is provided.
The utility model is to be achieved through the following technical solutions:
A kind of rail mining car, comprises wagon box, roller, between described roller, is connected by main shaft, and the midway location of described main shaft is provided with coaxially arranged brake equipment, and described brake equipment is connected with wagon box by the annulus on it.
As preferably, described brake equipment comprises annulus, and described annulus inside is provided with star-wheel, described star-wheel is provided with the groove of antisymmetric L shaped structure, in described groove, be provided with roller, the vertical plane of described groove is provided with spring spindle and the spring of horizontal arrangement, and described main shaft runs through star-wheel.
As preferably, described annulus and wagon box welding.
As preferably, described roller all contacts with the horizontal surface of annulus inside face, spring spindle vertical plane and groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, and the utility model can prevent mine car falling back in the time there is accident by actv., can carry out emergency brake, avoids accident harm further to expand.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to view;
Fig. 3 is B place partial enlarged drawing in Fig. 2.
In figure: 1. wagon box; 2. roller; 3. main shaft; 4. brake equipment; 5. annulus; 6. star-wheel; 60. grooves; 7. roller; 8. spring spindle; 9. spring.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of rail mining car, comprise wagon box 1, roller 2, between described roller 2, be connected by main shaft 3, the midway location of described main shaft 3 is provided with coaxially arranged brake equipment 4, described brake equipment 4 comprises annulus 5, described annulus 5 inside are provided with star-wheel 6, described star-wheel 6 is provided with the groove 60 of antisymmetric L shaped structure, in described groove 60, be provided with roller 7, the vertical plane of described groove 60 is provided with the spring spindle 8 and spring 9 of horizontal arrangement, and described main shaft 3 runs through star-wheel 6.Described brake equipment 4 is welded to connect with wagon box 1 by the annulus 5 on it, and described roller 7 all contacts with the horizontal surface of annulus 5 inside faces, spring spindle 3 vertical planes and groove 60.
Its detailed description of the invention is: in the time that this mine car meets accident, when main shaft 3 will rotate counterclockwise, main shaft 3 drives star-wheel 6 together to turn round, now roller 7 borrows friction force to press to the small end of groove 60, and by annulus 5 wedgings, star-wheel 6 being braked, this mine car motion stops; In the time that main shaft 3 clockwise rotates, roller 7 is rolled to the large end of groove 60, and now annulus 5 unclamps, and at this moment star-wheel 6 turns round, annulus 5 transfixions.The utility model can prevent mine car falling back in the time there is accident by actv., can carry out emergency brake, avoids accident harm further to expand.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
