Abstract
The utility model discloses a walking box structure of a coal mining machine, which comprises a walking box body, a gear rail wheel shaft (8) and a shaft sleeve (10); the walking box body is divided into a walking box shell body (1) and a front cover plate (7); and the walking box shell body (1) and the front cover plate (7) are detachably and fixedly connected. The utility model discloses the walking box structure of the coal mining machine, in which the detachment and the replacement of a walking box gear rail wheel and a guide slipper are convenient, the labor intensity is low and the downhole repair efficiency of the walking box is high.
Description
Technical field
The utility model relates to a kind of coal-winning machine, particularly a kind of coal-winning machine walking box structure.
Background technology
At the down-hole fully-mechanized mining working,, when changing and keeping in repair, must tear walking case or conveyer intermediate channel in advance open and just can pull down when the guide slip shoe and the rack rails wheel of coal-winning machine walking case breaks down.Very difficult at rack rails wheel of down-hole replacing or guide slip shoe, not only labour intensity is big, also influences the normal safety in production of mine, causes very big economic loss.
The utility model content
Technical problem to be solved in the utility model provides a kind of walking case rack rails wheel and guide slip shoe dismounting and changes conveniently, and labour intensity is low, the coal-winning machine walking box structure that the efficient of walking case down-hole maintenance is high.
In order to solve the problems of the technologies described above, the coal-winning machine walking box structure that the utility model provides, comprise walking case body, rack rails wheel shaft and axle sleeve, described walking case body is split as walking tank shell and front shroud, and described walking tank shell adopts removable fixedlying connected with described front shroud.
Describedly removablely be fixedly connected as described front shroud and adopt shop bolt to be connected with screw with described walking tank shell, integral body is strained with hydraulic bolt.
Be provided with vertical seam in the horizontal direction between described walking tank shell and the described front shroud.
Described rack rails wheel shaft adopts multidiameter and big pilot angle design.
Described axle sleeve adopts the fillet design.
Adopt the coal-winning machine walking box structure of technique scheme, before when changing rack rails wheel shaft and guide slip shoe, adopting during the monobloc container body structure, must dismantle The middle pan of scraper conveyor, take out from walking tank shell bottom, and the shell structure of employing kit form, then only need suitably raise complete machine, can pull down rack rails wheel and guide slip shoe from the side, improve the efficient of walking case down-hole maintenance.Front shroud not only adopts pin to be connected with screw with being connected between the tank shell of walking, and has also designed the transverse horizontal seam in the horizontal direction, increases bonding strength, again with the whole tension of hydraulic bolt, has strengthened the resistance to overturning of the case of walking.The rack rails wheel shaft adopts multidiameter and big pilot angle design, makes things convenient for its installation and removal; Axle sleeve adopts the fillet design, effectively prevents the generation of metal knurl.
In sum, the utility model is a kind of walking case rack rails wheel and guide slip shoe dismounting and changes conveniently that labour intensity is low, the coal-winning machine walking box structure that the efficient of walking case down-hole maintenance is high.
Description of drawings
Fig. 1 is a coal-winning machine walking case new structure front view;
Fig. 2 is a coal-winning machine walking case new structure lateral plan
Fig. 3 is a vertical view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2 and Fig. 3, walking case body is split as walking tank shell 1 and front shroud 7, front shroud 7 adopts shop bolt 4 to be connected with screw 3 with walking tank shell 1, whole with hydraulic bolt 5 tensions, be provided with vertical seam 2 in the horizontal direction between walking tank shell 1 and the front shroud 7, rack rails wheel shaft 8 adopts multidiameter and big pilot angle design, and axle sleeve 10 adopts the fillet design.
Referring to Fig. 1, Fig. 2 and Fig. 3, when coal-winning machine walking case rack rails wheel breaks down in the down-hole or guide slip shoe 6 serious wear need change component the time, adopt above-mentioned new structure to dismantle fast and to install, concrete grammar is as follows;
1, lays down one section cable trough on the corresponding drag conveyor;
2, pull down shop bolt 4, screw 3, protective sleeve and hydraulic bolt 5 in order;
3, pull down corresponding pin rail, complete machine raised suitable height, unload lower platen, rack rails wheel shaft 8 after, pull down the front shroud 7 of housing unit again;
4, can pull down guide slip shoe 6 and rack rails wheel 9 this moment from the side, overhaul and change.
Reversed in order therewith during installation.
