Description
Technical field
The utility model is related to a kind of constructing tunnel auxiliary equipment, specially a kind of tunnel inner wall trimming device.
Background technology
When digging tunnel, after mechanical excavation, tunnel inner wall also has the place of many out-of-flatnesses, needs to modify,
Arch with digging machine bucket repair owe less than, manually repair owe if waste time very much, need some tools to assist modifying.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and propose a kind of tunnel inner wall finishing
Device.
To achieve the goals above, the utility model uses following technical solution：
A kind of tunnel inner wall trimming device, including drill rod and fixed ear, drill rod by two block-shaped identical steel plates welding and
At steel plate top is wedge shape, and two bayonet locks are welded in steel plate lower part both sides；Fixed ear is welded on the both sides of digging machine bucket；Drill rod bottom
The handle portion at end is inserted into fixed ear, and bayonet lock is stuck in fixed ear.
The beneficial effects of the utility model are, are mounted on auxiliary finishing tunnel inner wall on digging machine bucket, are greatly saved
Human cost improves construction quality.
Description of the drawings
Fig. 1 is the overall structure diagram of the present apparatus.
Fig. 2 is the side schematic view of present apparatus drill rod.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Figures 1 and 2, a kind of tunnel inner wall trimming device, including drill rod 1 and fixed ear 2, drill rod is by two block-shaped phases
Same steel plate 3 is welded, and steel plate top 4 is wedge shape, and two bayonet locks 5 are welded in steel plate lower part both sides；Fixed ear is welded on digging machine
The both sides of bucket 6；The handle portion 7 of drill rod bottom end is inserted into fixed ear, and bayonet lock is stuck in fixed ear.
The drill rod of the present apparatus, the steel plate using two pieces of 2.5cm thickness weld together, wide 10cm, thick 5cm, overall length 105cm.
Bayonet lock, bayonet lock wide 5cm, long 10cm are being welded at the 25cm of drill rod bottom end.The fixed ear being welded on digging machine bucket, using two pieces
2.5cm steel plates weld together, thick 5cm, clear span 14cm, ear length 25cm.
The present apparatus is suitable for finishing weak surrounding rock, and when excavation first excavates arch as possible with digging machine hereinafter, vault owes peace at digging
Steel loading pricker, one people can install when installation, light simple.In use, drill rod is vertical with face, it can be according to the practical feelings in scene
Condition is in a certain angle.Drill rod is modified from the bottom up.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
