Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 7 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of road surface detection core-drilling machine, including
Adjustable shelf 5 and pedestal 8, the top of pedestal 8 is separately connected from left to right is fixed with holder 11, handle 10 and column 21, and pedestal 8
Both sides be rotatably connected to idler wheel 13, the screw rod 18 and column that adjustable shelf 5 is fixedly connected by fixed frame 19 and 20 bottom of handle
21 compositions slide up and down structure, and the seat board 12 that passes on left of adjustable shelf 5 is mounted with engine 9, the right side installation of adjustable shelf 5
It is fixed with reduction box 3, and the top and bottom of reduction box 3 are connected separately with 21 He of cooling water delivery pipe 1 and 6,2 root post of drilling pipe
Upright bar 2 is assisted to form Triangle-Profile, and the knot of the Triangle-Profile mode and 8 corresponding position of pedestal about the outer ring of drilling pipe 6
The structure of structure and adjustable shelf 5 matches, this structure is capable of sliding up and down for special operations frame 5, passes through supported at three point so that living
The operation of moving frame 5 is more stablized, and column 21 is symmetrically distributed on the upper and lower sides with the first side with auxiliary 2 Triangle-Profile range of upright bar
Plate 7 and the second side plate 16, the first side plate 7 is bolted constitutes fixed structure with pedestal 8, and the right side of the second side plate 16 passes through
Hinge 4 and the first side plate 7 constitute rotational structure, and the fixing bolt 14 that passes on left of the second side plate 16 is connected with fixed stand 15
Fixation is connect, this structure can form barrier to the outer ring both sides of drilling pipe 6, so as to make an uproar to what is generated in 6 operational process of drilling pipe
Sound is stopped that effective noise-decreasing endangers, and the rotational structure can facilitate staff to open the second side plate 16, will not
Increase the work load of construction personnel, the first side plate 7 and the second side plate 16 are double-layer structure, and the first side plate 7 and the second side
The medial surface of plate 16 is all evenly distributed with groove structure, this structure can further improve the first side plate 7 and the second side plate 16
Sound absorption qualities, the absorption by the groove structure to noise increases the rebound number of noise, consumes the energy of noise, reach
The effect for reducing noise, to reduce noise nuisance, the head of fixing bolt 14 is " Y " character form structure, this structure can increase
What human hand was made in processing puts forth effort area, so that staff can manually grasp fixing bolt 14 without tool
To make, is more convenient for using, the centre of the first side plate 7 and the second side plate 16 is fixed with visual window 17 by mosaic mode gluing, and
The inside of first side plate 7 and the second side plate 16 is respectively and fixedly provided with sound-proof material 23, the structure of this structure visual window 17 so that staff
Situation inside first side plate 7 and the second side plate 16 can be observed, and sound-proof material 23 can further increase the first side plate 7
With the soundproof effect of the second side plate 16, visual window 17 uses tempered glass material, and visual window 17 is double-layer vacuum structure, and
The position of visual window 17 and the position of drilling pipe 6 are corresponding, this structure not only makes visual window 17 have higher intensity, not rapid wear
It is bad, and its double-layer vacuum structure can stop sound transmission, to improve the noise reduction of the device, sound-proof material 23 is using poly-
Ester fiber material, and the embedded inside for being fixed on 16 double-layer structure of the first side plate 7 and the second side plate of sound-proof material 23, this material have
Superior deadening, and it can be with 16 collective effect of the first side plate 7 and the second side plate so that the soundproof effect of the device is more
It is good, to more reduce noise nuisance, rubber baffle 22, and rubber are installed between the left bottom and pedestal 8 of adjustable shelf 5
The inside of baffle 22 is embedded to be fixed with fine metal mesh 24, this structure can form one of barrier from the left side of drilling pipe 6, to noise into
Row blocking, and the fine metal mesh 24 can improve the intensity of rubber baffle 22 so that and rubber baffle 22 is more durable, rubber stop
The both sides up and down of plate 22 are fixed by screws respectively in adjustable shelf 5 and pedestal 8, and rubber baffle 22 is Folding wave knot
Structure, and the area equation of the area of fine metal mesh 24 and rubber baffle 22, this structure enable rubber baffle 22 to follow work
The up and down of moving frame 5 is folded or is stretched, so as to remain blocking to drilling pipe 6.
The operation principle of the present embodiment：The road surface detection core-drilling machine holds handle 10 by the equipment first
Carry out to test point, fixed pedestal 8 and ground by bolt, then start engine 9, engine 9 drives reduction box 3, subtracts
Fast case 3 drives 6 high speed rotation of drilling pipe, and staff makes adjustable shelf 5 move down by rotating clockwise handle 20, allows drilling pipe 6
Gradually go deep into the inside concrete of highway pavement, carries out boring and coring, will produce great noise, 2 root posts 21 in the process
With auxiliary upright bar 2 Triangle-Profile, and column 21 and auxiliary 2 Triangle-Profile range of upright bar are formed about the outer ring of drilling pipe 6
It is symmetrically distributed on the upper and lower sides between the first side plate 7 and the second side plate 16 and the left bottom and pedestal 8 of adjustable shelf 5 and installs
There are rubber baffle 22, the first side plate 7, the second side plate 16 and rubber baffle 22 to form the barrier of triangle to the outer ring of drilling pipe 6,
In 6 course of work of drilling pipe, effectively the propagation of noise is stopped, and weakens the energy of noise, to reach reduction noise
The effect of harm forms protective effect to the health of construction personnel, and then staff can be observed by visual window 17 and be bored
The operating condition of cylinder 6 catches " Y " character form structure on 14 head of fixing bolt, is rotated and backed out after drilling, you can
The second side plate 16 is rotated to 6 outside of drilling pipe directly, so that the second side plate 16 is opened, then rotates counterclockwise handle 20 again, make brill
Cylinder 6 is removed from pavement concrete, then removes drilling pipe 6, you can take out the concrete inner core drilled out, carry out the inspection of next step
It surveys.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacing, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection domain of invention.
