Minitype multifunctional heading machine
One, technical field:
The present invention is that the minitype multifunctional heading machine of usefulness is repaired in mining driving such as a kind of colliery and tunnel.
Two, background technology:
The cutting arm of existing minimole (100KW and following) cutting means all adopts and swings, cutting arm lower swing, cutterhead flexible (what have is flexible), body light (below 25 tons) on the whole, can in small-sized tunnel, carry out excavation operation, be subjected to the welcome in colliery.But its function singleness; And vibration is big when running into hard rock, and therefore the pick well damage can only be used for the driving in soft rock and coal seam, has limited the use of development machine.In addition,, increased equipment investment, and influenced job scheduling, improved operating cost, also be not easy to management because its function singleness when other operation of needs, then needs to be equipped with several work machinery.
Three, summary of the invention:
The purpose of this invention is to provide a kind of minitype multifunctional heading machine, it can not only tunnel, the hoeing operation, and can also realize mining mill dig, operations such as repair again in the tunnel, catalase, roadway support; And cutterhead can be realized rotating up and down with respect to cutting arm, makes operation more flexible.
For achieving the above object, the technical scheme that the present invention takes is: on the basis of original minimole, its cutting means is improved.Promptly include the cutterhead device of self-propelled crawler body, drive hoeing machine, cutting arm, cutting arm coupling arrangement, hinged pendulous device, cutterhead energy move left and right etc.Drive hoeing machine, cutting arm coupling arrangement all are fixed on the self-propelled crawler body, one end of cutting arm and cutting arm coupling arrangement hinge-coupled, the other end hinge-coupled of hinged pendulous device and cutting arm, cutterhead device are installed on the hinged pendulous device, also are detachable connection.
The form of structure of hinged pendulous device is a lot, can include compositions such as hinged disk, oscillating oil cylinder, fork I, fork II.Hinged disk and cutting arm hinge-coupled, oscillating oil cylinder, fork I, fork II are by hinge-coupled together, the other end of fork I and hinged disk hinge-coupled, the other end of fork II and cutting arm hinge-coupled, the other end of oscillating oil cylinder and cutting arm coupling arrangement hinge-coupled.Like this, hinged disk, cutting arm, fork II, fork I just form four-bar linkage structure, are acted on by oscillating oil cylinder on the pin joint of fork I and fork II, thereby realize that cutterhead device or other apparatus for work that is installed on the hinged disk swing
Because the present invention is provided with hinged pendulous device, hinged pendulous device and cutting arm hinge-coupled, cutterhead device and hinged pendulous device are for detachably to connect.Like this, the cutterhead device can be with hinged pendulous device, is the center of circle with the pin joint of hinged pendulous device and cutting arm, swings up and down.Make operation more flexible.When needs carry out other operation, only need the cutterhead device is unloaded from hinged pendulum device, change corresponding apparatus for work, as quartering hammer, Churn drill etc., just can realize corresponding operation; As change hydraulic breaking hammer, just can carry out crushing operation; Install brace summer, just can carry out the safety that front canopy support has guaranteed following operating personnel; As change the horizontal shaft type cutterhead, just can realize digging up mine, mill and dig and operation such as tunnel reparation; Or the like; So can realize several work.Therefore the present invention has a tractor serves several purposes, can carry out several work, and the operation maneuverability has reduced equipment investment, has saved fund, can improve the job scheduling of exploitation driving, has reduced characteristics such as cost of production.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present invention.
Five, the specific embodiment
Accompanying drawing is one embodiment of the present of invention, and it includes cutterhead device 5 that self-propelled crawler body 2, drive hoeing machine 1, cutting arm 4, cutting arm coupling arrangement 3, hinged pendulous device, cutterhead can move left and right etc.Drive hoeing machine 1, cutting arm coupling arrangement 3 all are fixed on the self-propelled crawler body 2, one end of cutting arm 4 and cutting arm coupling arrangement 3 hinge-coupled, the other end hinge-coupled of hinged pendulous device and cutting arm 4, cutterhead device 5 are installed on the hinged pendulous device, also are detachable connection.The form of structure of hinged pendulous device is a lot, and present embodiment includes compositions such as hinged disk 6, oscillating oil cylinder 9, fork I 7, fork II8.Hinged disk 6 and cutting arm 4 hinge-coupled, oscillating oil cylinder 9, fork I 7, fork II 8 are by hinge-coupled together, the other end of fork I 7 and hinged disk 6 hinge-coupled, the other end of fork II 8 and cutting arm 4 hinge-coupled, the other end of oscillating oil cylinder 9 and cutting arm coupling arrangement 3 hinge-coupled.Like this, hinged disk 6, cutting arm 4, fork II 8, fork I 7 just form four-bar linkage structure, act on by oscillating oil cylinder 9 on the pin joint of fork I 7 and fork II8, thereby realize that cutterhead device 5 or other apparatus for work that is installed on the hinged disk 6 swing.
When needs carry out other operation, only need cutterhead device 5 is unloaded from hinged disk 6, change required apparatus for work, as quartering hammer, Churn drill etc., just can carry out other operation.
Therefore the present invention has a tractor serves several purposes, can carry out several work, and the operation maneuverability has reduced equipment investment, has saved fund, can improve the job scheduling of exploitation driving, has reduced characteristics such as cost of production.
