The working principle is as follows:
when the device needs to be used, firstly, a worker connects an external charger with the storage battery pack 34 so as to charge the storage battery pack 34, and after the charging is finished, the connection is disconnected, and the worker manually pushes the movable frame 1 to move the movable frame 1 to a sampling place;
after the core barrel drill bit 23 moves to the upper portion of the road surface, the large electric telescopic rod 26 is controlled to stop stretching;
at the moment, a worker manually holds the movable frame 1 to avoid the movable frame 1 from shaking too severely, simultaneously, the controller control device starts to perform drilling work, the driving motor 28 starts to work, the driving motor 28 rotates to drive the square fixing block 29 to rotate, the square fixing block 29 is inserted into the fixing square groove 4 above the coring barrel 3 and is fixed through the fixing bolt 5, so that the square fixing block 29 and the coring barrel 3 are firmly fixed, the square fixing block 29 drives the coring barrel 3 to rotate, the rotation of the coring barrel 3 drives the reaming bit 20 to rotate, the coring barrel bit 23 also starts to rotate, when the rotation speed of the coring barrel bit 23 and the reaming bit 20 reaches the maximum, the large electric telescopic rod 26 is controlled to start to extend, and the coring barrel bit 23 starts to contact with the road surface along with the extension of the large electric telescopic rod 26, the road surface is drilled and cored to obtain a cored sample, the cored sample is gradually inserted into a drill bit 23 of the core barrel along with the continuous descending of the core barrel 3, when the core barrel 3 descends to a certain degree, a hole expanding drill bit 20 is in contact with the road surface at the moment, the road surface is subjected to hole expanding and drilling operation to expand the drilled hole, so that the core barrel 3 descends into the drilled hole, along with the continuous stretching of a large electric telescopic rod 26, the core barrel 3 is gradually inserted into the drilled hole, and when the large electric telescopic rod 26 completely stretches out, the road surface sampling is finished;
after the road surface sampling is finished, the large electric telescopic rod 26 is controlled to stop working at the moment, the micro electric push rod 31 is controlled to extend, the micro electric push rod 31 drives the right-angle ladder-shaped cushion block 32 to start moving, the right-angle ladder-shaped cushion block 32 is enabled to be in contact with the inverted ladder-shaped annular stop block 10, the sharp-angle end of the right-angle ladder-shaped cushion block 32 is inserted into the inclined-plane end of the inverted ladder-shaped annular stop block 10, so that the inverted ladder-shaped annular stop block 10 is lifted, the inverted ladder-shaped annular stop block 10 drives the adjusting rod 9 to start moving upwards along with the rising of the inverted ladder-shaped annular stop block 10, the adjusting rod 9 drives the second movable seat 15 to move upwards, one end of the rotating rod 16 is lifted upwards, the rotating rod 16 is supported by the matching of the supporting seat 19 and the supporting ring 18, so that the rotating rod 16 rotates around the supporting seat 19, the other end, as the rotating rod 16 drives the movable seat I14 to descend, the locking rod 13 starts to slowly move downwards, and meanwhile, the locking rod 13 also transversely moves for a short distance in the moving process, so that the locking rod 13 moves towards the center of the core barrel 3;
since the coring barrel 3 finishes coring, a coring sample is placed at the center of the core barrel 3, the locking rod 13 is contacted with the coring sample along with the movement of the locking rod 13, and the coring sample is fixed through the tooth-shaped side surface of the locking rod 13, so that the coring sample is fixed in the core barrel, the problem that the coring sample falls off when the core barrel 3 is taken out is avoided, and the adjusting rod 9 is also separated from the positioning circular groove 25 after the coring sample is fixed;
after the core sample is fixed, controlling the large electric telescopic rod 26 to start to contract, along with the contraction of the large electric telescopic rod 26 and the rotation of the driving motor 28, enabling the core taking barrel 3 to start to gradually rise from the inside of the drill hole, and stopping the control device when the core taking barrel 3 completely rises from the inside of the drill hole and reaches a certain height;
at the moment, a worker wears heat-insulating gloves, and manually rotates the adjusting handle 36, the adjusting handle 36 drives the manual adjusting rod 35 to start rotating, the manual adjusting rod 35 is connected with the adjusting stud 37 through threads, the manual adjusting rod 35 gradually rises along with the rotation of the adjusting handle 36, so that the manual adjusting rod 35 is separated from the positioning circular groove 25, and the reaming bit 20 is tightly connected with the external thread boss 6 through threads, so that the worker can rapidly detach the reaming bit 20 by manually rotating the reaming bit 20;
with the removal of the reamer bit 20, the lower end of the coring barrel 3 is completely exposed, the inner diameter of the lower end of the coring barrel 3 is larger than the outer diameter of a coring sample, at the moment, a worker controls the miniature electric push rod 31 to start to contract through the controller, the adjusting rod 9 pushes the spring baffle 11 to descend through the elasticity of the compression spring 12, the adjusting rod 9 is made to restore to the original position, the coring sample is in a loose state at the moment, and the coring sample falls off from the coring barrel 3 through the self gravity, so that the coring sample can be taken out from the coring barrel 3 quickly, and the worker can place the coring sample in a sample storage place manually;
after the coring sample is stored, the worker controls the miniature electric push rod 31 to extend out, so that the right-angle ladder-shaped cushion block 32 lifts the inverted ladder-shaped annular stop block 10, the adjusting rod 9 is retracted into the coring barrel 3, the worker can manually and quickly install the reaming bit 20 on the external thread boss 6, after the reaming bit 20 is butted with the coring barrel 3 to a certain extent, the worker controls the miniature electric push rod 31 to retract, so that the adjusting rod 9 extends out of the coring barrel 3 again, and the worker slightly rotates the reaming bit 20 to insert the adjusting rod into the positioning circular groove on the reaming bit 20, so that the reaming bit 20 is fixed;
after the reamer bit 20 is fixed, the worker rotates the adjusting handle 36 in the reverse direction manually, the adjusting handle 36 rotates in the reverse direction, the manual adjusting rod 35 is driven to rotate in the reverse direction, the manual adjusting rod 35 is slowly descended through the threaded connection between the manual adjusting rod 35 and the adjusting stud 37, the manual adjusting rod 35 is inserted into the positioning circular groove, when the adjusting handle 36 rotates, obvious resistance is sensed, the manual adjusting rod 35 is in contact with the lower surface of the positioning circular groove, the adjusting handle 36 can be stopped to rotate, the reamer bit 20 is completely installed, and the next use is waited.
In this device, through rolling ball sliding contact between right angle ladder form cushion 32 and the annular dog of the formula of falling trapezoidal 10, can make core barrel 3 take out the in-process in the rotation, can not produce too big noise and frictional resistance between right angle ladder form cushion 32 and the annular dog of the formula of falling trapezoidal 10, make things convenient for the use of device.
In this device, when coring barrel 3 carries out high-speed rotation, adjusting stud 37 then carries out sliding connection through ball 40 that rotation ring 38 top set up and drilling drive platform 27 to make coring barrel 3 do not influence adjusting stud 37's use again in the pivoted, adjusting stud 37 is then through the support of rotating ring 38 with ball 40, guarantees that adjusting stud 37's height can not change, thereby makes things convenient for the device to control reamer bit 20's installation and dismantlement.
The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
