Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In one embodiment, please refer to Figures 1-11 , a geological exploration reaming device, including a frustum 1, a reaming mechanism 2 and a suspension mechanism 3;

[0030] The main shaft 18 is rotatably connected to the middle of the frustum 1. The frustum 1 is horizontally arranged. The main shaft 18 is vertically arranged in the middle of the upper surface of the frustum 1. The lower end of the main shaft 18 is rotatably connected to the upper surface of the frustum 1. Six rotating seats 15 are arranged on the outer side of the upper surface of the frustum 1. The rotating seats 15 rotate synchronously with the main shaft 18 and are circumferentially symmetrically arranged relative to the center of the main shaft 18;

[0031] Suspension mechanism 3, a cross beam 4 is horizontally arranged above the frustum 1. The cross beam 4 is arranged in the left - right direction. Below the cross beam 4, a suspension frustum 112 is provided. The suspension frustum 112 is sleeved outside the main shaft 18. And a suspension rod is arranged on the upper surface of the suspension frustum 112 and fixedly connected to the lower surface of the cross beam 4. A suspension bracket 11 is arranged on the upper surface of the frustum 1. A support wheel 13 is arranged at the upper end of the suspension bracket 11. The support wheel 13 can roll on the upper surface of the suspension frustum 112. Therefore, through the cooperation of the support wheel 13 and the suspension frustum 112, the frustum 1 can rotate below the cross beam 4. And telescopic rods 5 in the left - right direction are arranged at the left and right ends of the cross beam 4. A fixed seat 8 is arranged at the end of the telescopic rod 5. A guide leg 9 is slidably connected to the middle of the fixed seat 8. A foot 10 is fixedly connected to the lower end of the guide leg 9. The foot 10 can be placed on the ground, so that the cross beam 4 and the frustum 1 can be stably located directly above the ground where hole expansion is required;

[0032] The hole expanding mechanism 2 is provided with mounting holes 19 on the side surface of the frustum 1. The mounting holes 19 are threadedly connected to the horizontally arranged first support slide rod 33 and the second support slide rod 34. Two first support slide rods 33 are arranged in parallel as a group, and the second support slide rod 34 is arranged between two adjacent groups of first support slide rods 33. Six groups of first support slide rods 33 are arranged on the outer side of the frustum 1. A first support seat 35 is slidably connected to the middle of the first support slide rod 33. One side of the first support seat 35 close to the frustum 1 is rotatably connected to the vertically arranged rotating shaft 39. The lower end of the rotating shaft 39 is fixedly connected to the upper end of the vertically arranged material taking screw column 38. A synchronous rotation assembly 37 is arranged above the rotating seat 15. The synchronous rotation assembly 37 can drive the rotating shaft 39 and the rotating seat 15 to rotate synchronously, so that the six material taking screw columns 38 rotate synchronously. A second support seat 36 is slidably connected to the middle of the second support slide rod 34. The upper surfaces of the second support seat 36 and the first support seat 35, which are far away from the frustum 1, are both vertically provided with limiting slide rods 41. The two ends of the connecting arm 42 are detachably connected to the limiting slide rods 41. Circular through holes are arranged at the two ends of the connecting arm 42. The cross section of the limiting slide rod 41 is circular. Therefore, the through holes at the two ends of the connecting arm 42 are respectively sleeved on two adjacent limiting slide rods 41. The inner diameter of the through hole of the connecting arm 42 is larger than the outer diameter of the limiting slide rod 41, and two adjacent connecting arms 42 are stacked together. Therefore, through the cooperation of the connecting arm 42 and the second support seat 36, the six first support seats 35 move synchronously closer to or away from the frustum 1. And one connecting arm 42 is respectively connected to the first support seat 35 and the second support seat 36 through the limiting slide rod 41. The twelve connecting arms 42 enable the six first support seats 35 to move horizontally synchronously, and the horizontal moving distances are also equal. A tension spring is arranged between the second support seat 36 and the frustum 1. The tension spring is sleeved on the outer side of the second support slide rod 34. During the rotation of the frustum 1, under the action of centrifugal force, the first support seat 35 and the second support seat 36 move away from the frustum 1, and as the speed increases, the centrifugal force also increases, so that the stretched length of the tension spring also increases, and thus the distance between the first support seat 35 and the frustum 1 also increases. Therefore, by controlling the rotation speed of the frustum 1, the distance between the first support seat 35 and the frustum 1 can be adjusted.

[0033] In a case of this embodiment, a first limiting post 16 that rotates synchronously with the rotating base 15 is provided on the upper surface of the rotating base 15, and a second limiting post 40 is provided at the upper end of the rotating shaft 39. The cross-sections of the first limiting post 16 and the second limiting post 40 are both polygonal structures. The synchronous rotation assembly 37 includes two deflecting plates 43 that rotate relative to each other. A deflecting rod 44 is vertically provided at the overlapping position of the two deflecting plates 43. The upper and lower sides of the deflecting rod 44 are respectively rotatably connected to the ends of the two deflecting plates 43, so that the two deflecting plates 43 are rotatably connected to each other through the deflecting rod 44. A synchronous rotating sleeve 45 is rotatably connected to the end of the deflecting plate 43 away from the deflecting rod 44. A first belt pulley 46 is fixedly connected to the outside of the synchronous rotating sleeve 45. The first belt pulley 46 is connected to a second belt pulley 48 through a synchronous belt 47. The second belt pulley 48 is fixedly connected to the end of the deflecting rod 44. A through hole with a polygonal structure is provided inside the synchronous rotating sleeve 45. Therefore, the through holes of the two synchronous rotating sleeves 45 are respectively sleeved outside the first limiting post 16 and the second limiting post 40. The first limiting post 16 makes the deflecting rod 44 rotate through belt transmission, and the deflecting rod 44 makes the second limiting post 40 rotate through belt transmission, so that the rotating shaft 39 and the rotating base 15 rotate synchronously through belt transmission. And during the lateral movement of the first support base 35, the deflecting plate 43 deflects adaptively, so that when the rotating shaft 39 moves, the rotating shaft 39 can still rotate synchronously with the rotating base 15.

[0034] In a case of this embodiment, a driving gear 17 is fixedly connected to the lower part of the main shaft 18. The outside of the driving gear 17 is meshed and connected to a driven gear 14. The driven gear 14 is fixedly connected to the outside of the rotating base 15. Therefore, the main shaft 18 makes the six rotating bases 15 rotate synchronously through gear transmission. And a rotation driving assembly 27 is provided on the cross beam 4. The rotation driving assembly 27 can drive the main shaft 18 and the turntable 1 to rotate relative to the cross beam 4. The rotation driving assembly 27 includes a motor fixing frame 21 provided on the right side of the lower surface of the cross beam 4. A first driving motor 22 is provided on the motor fixing frame 21. The output shaft of the first driving motor 22 is fixedly connected with a driving wheel 20. A driven wheel 23 is provided above the suspension bracket 11. The outside of the driven wheel 23 is in contact with the outside of the driving wheel 20. When the driving wheel 20 rotates, the driving wheel 20 makes the driven wheel 23 rotate through friction. Therefore, the first driving motor 22 can realize the rotation of the turntable 1 through the cooperation of the driving wheel 20 and the driven wheel 23. And a second driving motor 24 is provided on the right side of the upper surface of the cross beam 4. The output shaft of the second driving motor 24 is fixedly connected with a first helical gear 26. The first helical gear 26 is meshed and connected to a second helical gear 25. The second helical gear 25 is fixedly connected to the upper end of the main shaft 18. The upper part of the main shaft 18 is rotatably connected to the middle part of the cross beam 4. Therefore, the second driving motor 24 makes the main shaft 18 rotate through gear transmission.

[0035] In a case of this embodiment, telescopic rods 5 arranged in the left - right direction are slidably connected to the left and right ends of the cross - beam 4. And locking bolts 7 are threadedly connected to the left and right sides of the upper surface of the cross - beam 4. The locking bolts 7 can press against the telescopic rods 5, thereby restricting the extended length of the telescopic rods 5 through the locking bolts 7. And a gripper 6 is arranged on the upper surface of the cross - beam 4. The operator picks up the entire reaming device through the gripper 6. The side surface of a fixed seat 8 is rotatably connected to the end of the telescopic rod 5. A limiting groove 30 is arranged in the middle of the side of the fixed seat 8 close to the telescopic rod 5. Limiting blocks 28 are slidably connected to both the front and rear sides of the limiting groove 30. An arc - shaped groove is arranged on the side of the limiting block 28 close to the telescopic rod 5. Therefore, when the limiting block 28 abuts against the telescopic rod 5, the arc - shaped groove of the limiting block 28 can abut against the arc - shaped side surface of the telescopic rod 5. Thus, when the limiting block 28 abuts against the side surface of the telescopic rod 5, the fixed seat 8 will not rotate relative to the end of the telescopic rod 5. A limiting spring 29 is arranged between the two limiting blocks 28. The limiting spring 29 will push the limiting blocks 28 apart to both sides, so that the limiting blocks 28 can press against the outside of the telescopic rod 5. A buffer limiting plate 32 is arranged at the upper end of the guiding leg 9. A buffer spring 31 is arranged between the buffer limiting plate 32 and the fixed seat 8. The buffer spring 31 is sleeved outside the guiding leg 9.

[0036] During the implementation of this embodiment, when arriving at the site where reaming is required, each component of the reaming device is taken out of the packing box, and then the work of assembly and reaming is carried out.

[0037] Assembly steps: Pick up the cross - beam 4 through the gripper 6, pull out the telescopic rods 5. When the distance between the two fixed seats 8 meets the installation distance, tighten the locking bolts 7, and the length of the telescopic rods 5 is fixed. Squeeze the two limiting blocks 28 close to each other, rotate the guiding leg 9 to the vertical state, release the limiting blocks 28, and the limiting blocks 28 abut against the outside of the telescopic rods 5. At this time, the angle between the guiding leg 9 and the telescopic rods 5 is locked. Place the feet 10 stably on the ground, take out the first support slide rod 33 and the second support slide rod 34, install the first support slide rod 33 and the second support slide rod 34 in the installation holes 19 on the side of the frustum 1. Sleeve the tension spring outside the second support slide rod 34. Insert the first support seat 35 and the second support seat 36 outside the first support slide rod 33 and the second support slide rod 34. Fix the two ends of the tension spring to the side surfaces of the frustum 1 and the second support seat 36 respectively. At this time, take out the synchronous rotation assembly 37, sleeve the two synchronous rotating sleeves 45 outside the first limiting column 16 and the second limiting column 40 respectively. Adjust the positions of the first support seat 35 and the second support seat 36 back and forth. Sleeve the through - holes at both ends of the connecting arm 42 outside the limiting slide rods 41 on both sides. At this time, the relative positions between the first support seat 35 and the second support seat 36 are locked. The entire reaming device completes the assembly process. Place the frustum 1 directly above the ground where drilling is required.

[0038] Small-diameter hole punching process: Under the action of the tension spring, the second support seat 36 moves to a position close to the frustum 1. At this time, the first support seat 35 is attached to the outside of the frustum 1, and the material-taking screw columns 38 form a circular structure. Then, the second drive motor 24 is started. The second drive motor 24 drives the main shaft 18 to rotate through gear transmission. The main shaft 18 drives the rotating seat 15 to rotate through gear transmission. The rotating seat 15 drives the rotating shaft 39 to rotate through the belt transmission of the synchronous rotation assembly 37, so that the six material-taking screw columns 38 rotate. The operator presses the crossbeam 4 downward through the gripper 6, and the buffer spring 31 is stretched. The material-taking screw columns 38 are inserted into the ground from top to bottom. At this time, the material-taking screw columns 38 are screwed into the ground. When the material-taking screw columns 38 are screwed into a certain height, the crossbeam 4 is pulled upward to pull out the material-taking screw columns 38, so that a part of the soil is brought out. Then, it is pressed downward again. After repeating several times, the material-taking screw columns 38 can be completely inserted into the ground. At this time, six holes are screwed into the ground. The crossbeam 4 is lifted, and the frustum 1 is rotated by a certain angle by the first drive motor 22. The crossbeam 4 is pressed again, so that the material-taking screw columns 38 form six holes again. At this time, the holes intersect with each other, and a complete cylindrical groove, that is, the instrument placement hole, is formed on the ground. At this time, the small-diameter instrument placement hole is completed with the hole punching process.

[0039] Large-diameter hole punching process: When the small-diameter instrument placement hole is completed with the hole punching process, the first drive motor 22 is started. At this time, the first drive motor 22 drives the frustum 1 to rotate through the cooperation of the driving wheel 20 and the driven wheel 23. The initial state of the frustum 1 is at a relatively low rotation speed. At this time, the material-taking screw columns 38 revolve along the center of the main shaft 18, so that the side protrusions of the instrument placement hole are completely smoothed. Then, the angular velocity of the first drive motor 22 is gradually increased, so that the rotation speed of the frustum 1 increases. At this time, under the action of the centrifugal force, the first support seat 35 and the second support seat 36 move synchronously in a direction away from the frustum 1, and the diameter of the instrument placement hole is gradually increased. And if the material-taking screw columns 38 encounter stones that cannot be broken, the material-taking screw columns 38 will be pushed inward, so that the material-taking screw columns 38 can avoid the stones, thus preventing the stones from damaging the material-taking screw columns 38. And at this time, the first drive motor 22 and the second drive motor 24 can be stopped, and the operator takes out the stones through tools such as pickaxes. Then, the hole expanding device is started again. As the rotation speed of the frustum 1 gradually increases, when the diameter of the instrument placement hole meets the use requirements, the first drive motor 22 and the second drive motor 24 are stopped, and the crossbeam 4 is loosened. Under the action of the buffer spring 31, the material-taking screw columns 38 move upward with the crossbeam 4, and the operator cleans the broken soil inside the instrument placement hole. At this time, the relevant instruments can be installed.

[0040] For the folding process of the reaming device, remove the synchronous rotation assembly 37 and the connecting arm 42, remove the first support base 35 and the second support base 36 from the first support slide bar 33 and the second support slide bar 34, remove the first support slide bar 33 and the second support slide bar 34, press the limit blocks 28 closer to each other so that the limit blocks 28 are disengaged from the telescopic rod 5, rotate the guiding leg 9 to a state parallel to the telescopic rod 5, loosen the locking bolt 7, insert the telescopic rod 5 back into the inside of the cross beam 4, and when the support feet 10 move below the cross beam 4, tighten the locking bolt 7. The suspension mechanism 3 is completed for folding. At this time, put each fitting of the reaming device into the storage box.

[0041] The present invention is applicable to a geological exploration reaming device. By freely disassembling and assembling the synchronous rotation assembly 37 and the connecting arm 42, the entire reaming device can be disassembled into small-sized fittings, so that during the transfer process, the reaming device can be disassembled into small-sized components and put into the storage box, enabling the staff to move the reaming device more conveniently in the wild. Moreover, the distance between the feeding spiral column 38 and the frustum 1 can be adjusted, allowing the operator to more conveniently adjust the size of the reaming hole.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
