Detailed Description
The technical solutions of the symmetrical embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 6 of the accompanying drawings, and it is apparent that the embodiments of the present invention include, but are not limited to, the embodiments described below. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a device for exploring and sampling tunnel rock and soil, which has the following technical scheme:
referring to fig. 3, after the drill pipe is driven by the drill machine 5 to complete threaded connection between drill pipes, the drill pipe is driven to rotate, so that the drill bit at the head of the first drill pipe is driven to rotate, and the drill machine 5 and the drill pipe are driven to slowly move downwards by hydraulic driving, at this time, the wire rope 11 is wound under the action of the torsion spring, and the ratchet wheel one 2501 and the ratchet wheel two 2502 slip on the pawl one 2601 and the pawl two 2602 respectively, so that the tensile force applied to the drill machine 5 is small. When rig 5 descends and removes to guide bar 3 middle part, balancing weight 31 can support mounting bracket 29 to promote mounting bracket 29 to overcome the appeal of magnet body one and remove downwards, avoid mounting bracket 29 and rig 5 to take place to interfere, mounting bracket 29 can produce an ascending frictional force this moment, frictional force is opposite with the gravity direction of balancing weight 31, consequently can offset the moment of torsion of balancing weight 31 that a part of rig 5 received, thereby make the power that rig 5 both ends received approximately equal, make support 4 can not produce great moment of torsion, take place to warp the damage, the life of the exploration sampling equipment of extension tunnel ground. In order to ensure that the gravity center of the balancing weight 31 is far away from the steel wire rope 11, the horizontal part of the balancing weight 31 is made of a composite material with smaller density. The counterweight 31 and the wire rope 11 may be connected directly to the support 4 in addition to the drill 5.
When the drilling machine 5 is lowered to the lowest position, the distance between the motor and the clamping part 7 is larger than the length of the auxiliary clamping jaw 30 and the height of the pushing plate, so that the drilling machine 5 does not interfere with the auxiliary clamping jaw 30 and the pushing plate. When the drill bit of the drilling machine 5 stops rotating, the clamping part 7 can clamp the drill pipe, so that the phenomenon that the drill pipe is reversed when the drill bit is in threaded connection with the drill pipe, and the drill pipe is loose in connection is avoided. When the drill bit is disconnected from the drill pipe, the support 4 drives the drilling machine 5 to move upwards. At this time, because the magnetic field intensity of the second magnet 3202 is greater than that of the third magnet 3203, under the action of the second magnet 3202, the weight 31 drives the mounting frame 29 to move upwards, and the direction of the friction force generated by the mounting frame 29 is vertical downward and the direction of the friction force generated by the mounting frame is the same as the gravity direction of the weight 31, so that the force applied by the drilling machine 5 is the gravity of the weight 31 plus the friction force.
Referring to fig. 4, when the drilling machine 5 moves upwards, the driving shaft 10 is pulled to release the steel wire rope 11, so as to drive the driving shaft 10 to rotate reversely, so that the ratchet wheel 2501 and the ratchet wheel 2502 at two ends of the driving shaft 10 are driven to rotate, the ratchet wheel 2501 drives the disc 2401 to rotate through the pawl 2601, the disc 2401 drives the worm 2301 and the rotating shaft three 1903 to synchronously rotate, so as to drive the turbine 2201 to rotate, the turbine 2201 drives the rotating shaft two 1902 to rotate, and the rotating shaft three 1903 transmits kinetic energy to the input shaft 902 through the bevel gear, so that the input shaft 902 drives the conveying belt 901 to move towards the direction close to the circular arc slideway 13. Since the interval between the baffles 12 is equal to the diameter of the drill pipe, and the interval between the fixing blocks 16 at both sides of the support 4 is greater than the diameter of the drill pipe by 1-2cm, the drill pipe can be kept in a vertical state on the conveyor belt 901 for movement because the baffles 12 and the fixing blocks 16 restrict the drill pipe in four directions. In order to avoid tilting of the drill pipe, the spacing between the fixed blocks 16 should not be too great. When the drill 5 is moved to the highest point, the conveyor 901 moves a drill pipe diameter plus the thickness of the baffle 12. Meanwhile, the rotation of the ratchet wheel II 2502 pushes the disc II 2402 to rotate through the cooperation of the ratchet wheel II 2602, the disc I2401 drives the worm II 2302 and the rotating shaft to synchronously rotate, the worm II 2302 drives the rotating shaft V1905 to rotate through the turbine II 2202, and the rotating shaft V1905 drives the rotating shaft I1901 to rotate through gear transmission, so that the baffle 12 is driven to rotate. When the drilling machine 5 is moved to the highest point, the apron 12 is rotated 180 °. The wire 11 enters and exits the inside of the box 20 through the through hole 28 of the first rotary shaft 1901, and the wire 11 does not interfere with the push plate because the path of the wire 11 is located at the rotation center of the push plate. Since the wire 11 needs to drive a large number of parts, the tension generated on the drill 5 increases and is substantially equal to the force of the counterweight 31.
The first rotation shaft 1901 drives the front push plate 1701 and the rear push plate 1702 to rotate synchronously, and because the circle centers of the first rotation shaft 1901 and the circular arc slide way 13 are arranged eccentrically, the length difference between the front baffle 12 and the rear push plate 1702 is equal to the distance between the circle center of the first rotation shaft 1901 and the circle center of the circular arc slide way 13, the rear baffle 12 contacts the drill pipe when the conveyer 901 approaches to the upper part of one end of the circular arc slide way 13, and the front baffle 12 is positioned in front of the drill pipe before the drill pipe enters the area to be fed. The rear push plate 1702 and the front push plate 1701 cooperate with the circular arc chute 13 to restrict the four directions of the drill pipe, so that the drill pipe can be kept vertically movable. Because the back push plate 1702 needs to do work on the drill pipe, the number of the push plates is two, the bending stress of the back push plate 1702 is reduced, the stability of pushing the drill pipe is improved, and the front push plate 1701 is positioned between the two back push plates 1702, so that the overall stability of the drill pipe is ensured. Because of the eccentric arrangement of the first shaft 1901, the rear push plate 1702 will separate from the drill pipe as the push plate moves the drill pipe over the pilot hole 6, preventing the drill pipe from rotating with the interference push plate. Because the first rotating shaft 1901 is driven by the worm and gear, the self-locking property of the worm and gear ensures that when the drilling machine 5 stops moving, the pushing plate can not rotate continuously due to inertia, so that the matching error of the pushing plate and the conveyer belt 901 is caused, and the operation accuracy of the tunnel rock and soil exploration sampling equipment is improved.
Referring to fig. 2, when a drill pipe is pushed away by a push plate, the next drill pipe is moved to an end of the circular arc chute 13 near the conveyor 901 by the conveyor 901, and the baffle 12 of the advancing direction of the drill pipe is moved to a curved portion of the conveyor 901, so that the drill pipe lacks a constraint in one direction, and in order to avoid tilting of the drill pipe, the interval between the fixing blocks 16 is smaller than the diameter of the drill pipe by 1-2cm, so as to clamp the drill pipe, so that the drill pipe can be separated by the rear push plate 1702. The stability of the drill pipe moving to the arc slide way 13 can be improved by the phase-cut blocks 18, but the arc slide way 13 is too close to the conveying belt 901, so that interference with the baffle plate 12 is avoided, the notch 14 is formed in the arc slide way 13, the length of the baffle plate 12 is set to be 1/2 of the diameter of the drill pipe so as to avoid the influence of the notch 14 on the movement of the drill pipe, meanwhile, the baffle plate 12 is arranged in the middle of the conveying belt 901, the baffle plate 12 is ensured to be fully contacted with the drill pipe, and the stability of the feeding device is improved. The length of the screw threads at the two ends of the drill pipe is 1.5 times of the diameter, so that the baffle 12 is set to be twice of the diameter of the drill pipe, the baffle 12 can be contacted with the largest outer side wall of the drill pipe, loosening of the drill pipe in the conveying process is avoided, and stable and automatic feeding of the exploration sampling equipment for the tunnel rock and soil is ensured.
Referring to fig. 3, when the drilling machine 5 moves to the middle part of the guide rod 3, the mounting frame 29 is attracted by the first magnet 3201, and because the magnetic field intensity of the first magnet 3201 is larger than the sum of the magnetic field intensity of the second magnet 3202 and the magnetic field intensity of the third magnet 3203, the auxiliary clamping jaw 30 stops moving at the middle part of the guide rod 3, so that the auxiliary clamping jaw 30 is attached to the middle part of a drill pipe, the stability between the auxiliary clamping jaw 30 and the drill pipe is improved, the next drill pipe is moved to the upper part of the positioning hole 6 by the waiting push plate, and when the drill pipe moves to the upper part of the positioning hole 6, the drill pipe is stably attached to the auxiliary clamping jaw 30 under the action of the third magnet 3203, and the drill pipe is in a vertical state. The length of the auxiliary clamping jaw 30 is 1/20 of that of the drill pipe, when the length of the auxiliary clamping jaw 30 is smaller than 1/20, the limiting torque of the two ends of the auxiliary clamping jaw 30 on the drill pipe is smaller, the drill pipe is easy to shake and incline, and when the length of the auxiliary clamping jaw 30 is larger than 1/20, the length of the auxiliary clamping jaw 30 is larger than the interval between the drilling machine 5 and the clamping part 7 when the drilling machine 5 descends to the lowest point, and interference can occur. Under the effect of the magnet III 3203, the drill pipe slowly moves downwards to be in contact with the last drill pipe, so that screw thread collision damage between the drill pipes is avoided, the service life of the drill pipe is prolonged, the use failure rate of the tunnel rock and soil exploration sampling equipment is reduced, at the moment, the drilling machine 5 descends to be in contact with the drill bit and is then started, the drill machine 5 is driven to be in threaded connection, and the downward movement of the next drill pipe is realized. The feeding process of the whole drill pipe does not need to be assisted manually, so that the automation degree of the exploration sampling equipment of the tunnel rock soil is improved, the use fault rate of the exploration sampling equipment of the tunnel rock soil is reduced, and the labor cost is reduced. Meanwhile, the problem that personal safety of operators is damaged due to collision between operators and a drilling machine caused by improper matching is avoided.
To avoid friction between the circular arc chute 13, the rear push plate 1702, the front push plate 1701, the baffle 12, the auxiliary clamping jaw 30 and the fixed block 16 and the drill pipe, and scratch the surface of the drill pipe, the service life of the drill pipe is reduced, the circular arc chute 13, the rear push plate 1702, the front push plate 1701, the baffle 12, the auxiliary clamping jaw 30 and the drill pipe can be made of high polymer materials with hardness lower than the minimum hardness HRC20 of carbon steel, such as polyethylene, polypropylene and the like.
