Abstract
The utility model relates to a critical piece of a coal mine laneway road-header, in particular comprises a walking part of the road header, which is provided with an apron wheel, a tensioner group, an apron wheel frame, tensioning cylinders, wherein a tensioner group which is connected with the apron wheel is extended to the inner-cavity of the apron wheel through an interconnecting piece, an interchangeable steel frame or a buffer group spring are mounted between the tensioning cylinders which are connected with the apron wheel frame and the interconnecting piece. The tensioner group buffer spring or the steel frame can be selectively mounted on the device, the device has advantages of simple structure and convenient for different demands of users.
Description
Technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of development machine running part.
Background technology
When excavation operation, running part can be subjected to impact force with development machine in the colliery, if there is not the absorption of buffer gear under some geological conditions, these power may cause creeper tread to damage.And impact force is less under some geological conditions, does not need buffer gear, and the cost of buffer spring is higher.
The utility model content
The purpose of this utility model is to provide a kind of development machine running part, can not need any change just can select dress buffer spring group or rigid trestle according to the running part structure of different demand choosing dress buffer springs or rigid trestle, makes things convenient for the user to select.
The technical solution of the utility model is:
A kind of development machine running part, be provided with crawler belt, tensioning wheels, track frame, tensioning hydro-cylinder, the tensioning wheels that link to each other with crawler belt extend in the crawler belt chamber by connector, connector and be connected in interchangeable rigid trestle or buffer spring group are installed between the tensioning hydro-cylinder on the track frame.
The beneficial effects of the utility model are:
The utility model development machine running part device does not need any change just can select buffer spring group or rigid trestle are installed, and is simple in structure, makes things convenient for the user to select.
Description of drawings
Fig. 1 installs the structure chart of rigid trestle for the utility model.
Fig. 2 installs the structure chart of buffer spring group for the utility model.
Among the figure, 1 crawler belt; 2 tensioning wheels; 3 track frames; 4 rigid trestles; 5 buffer spring groups; 6 tensioning hydro-cylinders; 7 connectors; 8 crawler belt chambeies.
The specific embodiment
As shown in Figure 1, present embodiment development machine running part device is provided with crawler belt 1, tensioning wheels 2, track frame 3, rigid trestle 4, tensioning hydro-cylinder 6, crawler belt 1 is connected with tensioning wheels 2, tensioning wheels 2 extend in the crawler belt chamber 8 by connector 7, connector 7 and be installed between the tensioning hydro-cylinder 6 on the track frame 3 rigid trestle 4 can be installed.
As shown in Figure 2, present embodiment development machine running part device is provided with crawler belt 1, tensioning wheels 2, track frame 3, buffer spring group 5, tensioning hydro-cylinder 6, crawler belt 1 is connected with tensioning wheels 2, tensioning wheels 2 extend in the crawler belt chamber 8 by connector 7, connector 7 and be installed between the tensioning hydro-cylinder 6 on the track frame 3 buffer spring group 5 can be installed.
Rigid trestle 4 in the utility model and buffering groups of springs 5 can be exchanged in track frame chamber 8, thereby can select to install the device of buffer spring group or rigid trestle, satisfy requirements of different users.
