Abstract
The utility model relates to a tunnel boring machine. The left side and the right side of the rack are respectively hinged with a walking crawler belt through a bearing and a chain wheel, the front end of the rack is hinged with a large frame through a hinge shaft, a power head is matched on the large frame in a sliding manner, a large frame lifting oil cylinder is hinged between the power head and the rack, a mud pump and a drill rod motor are fixed at the upper end of the power head, a main buckle is fixed at the lower end of the power head, a drill bit is fixed at the main buckle, and a hydraulic and form walking controller is fixed on the; the drill rod motor is driven by the power head. The tunnel shaft excavating machine can complete excavation of a tunnel shaft, and is small in size, small in occupied space and good in stability.
Description
Technical Field
The utility model belongs to the rig, in particular to tunnel boring machine.
Background
The original tunnel drilling machine is large in size, large in occupied space, incapable of allowing a small tunnel to pass through, square column-supported, and poor in flexibility and stability.
Disclosure of Invention
In order to overcome prior art's shortcoming, the utility model provides a tunnel boring machine, it can accomplish the excavation of tunnel shaft, and is small, and occupation space is little, and stability is good.
The utility model provides a technical scheme that its technical problem adopted is: the left side and the right side of the rack are respectively hinged with a walking crawler belt through a bearing and a chain wheel, the front end of the rack is hinged with a large frame through a hinge shaft, a power head is matched on the large frame in a sliding manner, a large frame lifting oil cylinder is hinged between the power head and the rack, a mud pump and a drill rod motor are fixed at the upper end of the power head, a main buckle is fixed at the lower end of the power head, a drill bit is fixed at the main buckle, and a hydraulic and form walking controller is fixed on the; the drill rod motor drives the drill bit through the power head.
The utility model discloses can accomplish the excavation of tunnel shaft, it is small, occupation space is little, and stability is good.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a front view of the present invention;
fig. 2 is a left side view of the present invention;
fig. 3 is a schematic view of the folded state of the present invention.
Detailed Description
As shown in fig. 1 and 2, the left side and the right side of a frame 9 are respectively hinged with a walking crawler 10 through a bearing and a chain wheel, the front end of the frame 9 is hinged with a big frame 3 through a hinge shaft 8, a power head 5 is matched on the big frame 3 in a sliding way, a big frame lifting oil cylinder 7 is hinged between the power head 5 and the frame 9, a mud pump 6 and a drill rod motor 13 are fixed at the upper end of the power head 5, a main buckle head 4 is fixed at the lower end of the power head 5, a drill bit (not shown in the figure) is fixed at the main buckle head 4, and a hydraulic and form walking controller 11 is fixed; the drill rod motor 13 drives the drill bit through the power head 5.
The big frame 3 adopts two round steel columns, so that the flexibility and the stability of the big frame 3 are improved.
The lower end of the big frame 3 is fixed with a lower frame 1, and the lower frame 1 is fixed with four small frame hydraulic support legs 2. The support is used for supporting the small frame 1 and the large frame 3 during working, and leveling is carried out, so that the drill bit drills vertically.
The frame 9 fixes four frame hydraulic legs 12. For supporting the frame 9 during operation.
As shown in fig. 3, the large frame 3 and the small frame 1 can be folded to reduce the height of the whole vehicle.
