Specific implementation mode
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to According to.
The embodiment of the present invention:It includes as shown in figures 1-6 bottom plate 6, bottom plate 6 that corning machine, which is adjusted, in a kind of dual-purpose type On a wherein head end be fixed with pedestal 8,1 root post 17 is equipped on pedestal 8 vertically, further includes having the slideway 1 that can be inserted in column 17, It is provided along its length slideway gear 9 outside slideway 1, be connected on slideway 1 to slide up and down along its length Sliding block 2, sliding block 2 are equipped with motor 11 and retreat operation handle 5, and 11 bottom of motor is connected with drill bit 12, further includes having to be inserted in The sleeve 15 of column 17,15 head end of sleeve are vertically connected with the sleeve crossbeam 18 that can be inserted in slideway 1.
Use step other than operating difference in coring for the road surface coring situation present invention, remaining step and one As corning machine using sequence it is almost the same.
A, first the present apparatus is moved to and needs drill core position;
B, the other end of the separate pedestal 8 of bottom plate 6 is pushed down using automobile or other weights;
C, slideway 1 is socketed in outside column 17,12 head end of drill bit can face road surface at this time;
D, connect electric power, by control descending operation handle 5 make drill bit 12 along balladeur train 10 decline, treat test position into Row drilling;
E, after reaching the round trip drilling depth, drill bit 12 is detached with motor 11;
F, it transfers to drill bit 12 to carry out coring from drilling, so far, completes the coring of a round trip;
H, 3~7 are repeated, until being drilled into predetermined depth.
When needing to carry out drill core to tunnel-liner, then proceed as follows:
A, first the present apparatus is moved to and needs drill core position;
B, the other end of the separate pedestal 8 of bottom plate 6 is pushed down using automobile or other weights;
C, sleeve 15 is socketed in outside column 17 so that 18 face tunnel exterior wall of sleeve crossbeam, while slideway 1 is socketed in set Outside cylinder crossbeam 18, drill bit 12 is perpendicular to the ground at this time.
Other steps and pavement construction step D~H.
The column 17 and sleeve 15 are arranged at intervals with multiple fixed limit screw holes along its length.When sleeve 15 is socketed At 17 outside of column, pass through fixed limit screw hole that the two can be fixed together by limiting fixing bolt 14.And sleeve 15 slide up and down along column 17, and the fixed limit screw hole of different height is fixed on by limiting fixing bolt 14, you can real The adjusting of existing 18 height of sleeve crossbeam, so as to carry out coring to the tunnel side wall of different height.
The sleeve crossbeam 18 is equipped with fixed limit screw hole, and fixed limit screw hole is also provided on slideway 1.When sleeve cross When beam 18 is inserted in slideway 1, passes through fixed limit screw hole that can be fixed 2 by limiting fixing bolt 14, avoid drilling The vibration band sliding way 1 that drill bit 12 generates in the process is shaken together, influences the stability of equipment.When slideway 1 is socketed in column 17 When external, pass through the fixed limit screw hole of slideway 1 and column 17 that the two can be fixed together by limiting fixing bolt 14.
When column 17 is inserted in sleeve 15, and sleeve crossbeam 18 is inserted in slideway 1, between slideway 1 and sleeve 15 or column 17 It is connected with supporting rod 16.Supporting rod 16 can realize the fixation to slideway 1 at the same time it can also play a supporting role to slideway 1.Support The head end of bar 16 is fixed by limiting fixing bolt 14.
The sliding block 2 is each side connect by 1 rotation axis mechanism 3 with motor 11.The rotation axis mechanism 3 includes The pin hole being respectively welded on sliding 2 and motor 11, by passing through the pin hole of the two that can connect sliding block 2 and motor 11 pin It is connected together.The rotation axis mechanism 3 is similar to the hinge structure for fixed door, window, other achievable sliding blocks 2 and motor 11 Between the structure that is rotatablely connected also may be used.In boring procedure, after step D, step E is:After reaching the round trip drilling depth, this When solution remove wherein 1 in 2 between sliding block 2 and motor 11 rotation axis mechanisms 3, by removing wherein 1 during releasing Pin 4 in a rotation axis mechanism 3, both similar to the axis pin in hinge, you can so that the rotation axis mechanism 3 is detached with motor 11, Motor 11 can be rotated around other 1 rotation axis mechanism 3 at this time, so that motor 11 is staggered with 12 position of drill bit.Thus Motor 11 need not be disassembled from sliding block 2, you can fast implement postorder core work.After coring structure, then it will divide It is connected from the rotation axis mechanism 3 fallen, you can carry out drilling work next time.
Handle 7 is provided on the bottom plate 6, due to increasing bottom plate 6 so that quality of the present invention is more than existing coring Machine, therefore remote equipment can conveniently be removed by being provided with handle 7.
The bottom plate 6 is equipped with leveling bolt 9.When encountering ground out-of-flatness, by rotate leveling bolt 9, make its with Ground contacts, and to avoid boring procedure bottom plate 6 from vibrating, influences the drilling of drilling 12.
6 length and width dimensions of the bottom plate are:60~120cm*30~80cm.By the way that pedestal 7 is fixed on the larger bottom of area On plate 5, bottom plate 6 is compressed far from weights such as drill bit vehicles when coring, avoid beating expansion bolt, save the time in bottom plate 6.
The leveling bolt 9 is positioned close to 6 both sides of bottom plate of drill bit 12.Since the bottom plate 6 far from pedestal 8 uses automobile Or other weights are pushed down, therefore the bottom plate 6 pushed down can keep contacting well with ground, therefore only need at the bottom of 8 both sides of pedestal Leveling bolt 9 is set on plate 6.
The pedestal 8 is fixed on by bottom plate positioning bolt 13 on bottom plate 6, easy to disassemble and replacement component.
