Abstract
The utility model relates to an important component of a coal mine dintheader, in particular to a dintheader cutting component. A cutting component mounting position which is connected with a dintheader revolving platform is arranged at one end of the dintheader cutting component; a cutting hoist cylinder mounting position which corresponds to a dintheader cutting hoist cylinder is arranged on the dintheader cutting component; an extensible cutting arm or an inextensible cutting arm is arranged at the other end of the dintheader cutting component. By adopting the important component of the coal mine dintheader, the extensible cutting component device or the inextensible cutting component device can be selected to be installed on equipment according to different hardness of coal rocks, so that the structure is simple and the requirements of different users are satisfied.
Description
Technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of tunneling machine cutting portion.
Background technology
When excavation operation, because the geologic condition difference, some situation need be used telescopic cutting units with development machine in the colliery, so that increase the cut scope, increases work efficiency; And some situation needs cutting units to have good intensity to adapt to the cut of high rigidity coal petrography, then needs non-telescoping cutting units.Telescopic cutting units apparatus structure complexity, intensity difference damages easily.
The utility model content
The purpose of this utility model is to provide a kind of tunneling machine cutting portion, can adorn scalable or non-telescoping cutting units device according to different demands choosings, does not need any change just can select and adorns scalable or non-telescoping cutting units device, makes things convenient for the user to select.
The technical solution of the utility model is:
A kind of tunneling machine cutting portion, described tunneling machine cutting portion one end is provided with the cutting units installation position that is connected with the development machine panoramic table, tunneling machine cutting portion is provided with and the corresponding cut hoist cylinder of tunneling machine cutting hoist cylinder installation position, and the tunneling machine cutting portion other end is provided with extension type cutting arm or non-telescoping formula cutting arm.
The beneficial effects of the utility model are:
1, the utility model tunneling machine cutting part device does not need any change just can select and adorns scalable or non-telescoping cutting units device.
2, the utility model can be selected telescopic cutting units device or non-telescoping cutting units device are installed on an equipment according to different coal petrography hardness, satisfies requirements of different users.
Description of drawings
Fig. 1 is a scalable cutting units structural representation of the present utility model.
Fig. 2 is the non-telescoping cutting units structural representation of the utility model.
Among the figure, 1 extension type cutting arm; 2 cut hoist cylinder installation position I; 3 cutting units installation position I; 4 non-telescoping formula cutting arms; 5 cut hoist cylinder installation position II; 6 cutting units installation position II; 7 telescopic oil cylinders.
The specific embodiment
As shown in Figure 1, the utility model is a tunneling machine cutting portion, tunneling machine cutting portion one end is provided with the cutting units installation position I 3 that is connected with the development machine panoramic table, tunneling machine cutting portion is provided with and the corresponding cut hoist cylinder installation position I 2 of tunneling machine cutting hoist cylinder, the tunneling machine cutting portion other end is provided with extension type cutting arm 1, and extension type cutting arm 1 drives flexible by telescopic oil cylinder 7.
As shown in Figure 2, the utility model is a tunneling machine cutting portion, tunneling machine cutting portion one end is provided with the cutting units installation position II 6 that is connected with the development machine panoramic table, tunneling machine cutting portion is provided with and the corresponding cut hoist cylinder installation position II 5 of tunneling machine cutting hoist cylinder, and the tunneling machine cutting portion other end is provided with non-telescoping formula cutting arm 4.
The utility model has the tunneling machine cutting portion of extension type cutting arm 1, with the tunneling machine cutting portion that has non-telescoping formula cutting arm 4, has identical installation position (being installing hole).So just can be installed on the same development machine panoramic table, reach the exchange purpose of scalable and non-telescoping cutting units.
