Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to a device for preventing vibration and displacement of geological exploration drilling equipment. Background Art

[0002] During geological exploration, drilling equipment is needed to analyze the structure and composition of rock and soil. During the drilling process, the drilling equipment may be affected by vibration and tilt, deviating from the predetermined drilling direction. In order to prevent the drill rod on the drilling equipment from vibrating and deviating from the predetermined drilling direction, lubricant needs to be applied to the outside of the drill rod.

[0003] However, in actual work, after the staff has prepared the lubricant, they apply it to the outer surface of the drill pipe during the drilling process. Since there is a close synergistic relationship between the amount of lubricant applied and the drill pipe rotation speed, there will be certain errors in manual application, resulting in the amount of lubricant applied on the outer surface of the drill pipe being difficult to control, which in turn affects the effect of preventing vibration displacement. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for preventing vibration and displacement of geological exploration drilling equipment, which can quantitatively design the amount of lubricant according to the downward movement length of the drill rod; on the one hand, it can prevent excessive lubricant from being applied to the surface of the drill rod, thereby affecting the effect of preventing vibration and displacement; on the other hand, it can save the use of lubricant, save resources and costs.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for preventing vibration and displacement of geological exploration drilling equipment, comprising a base of movable design, a quantity control component provided on the base, the quantity control component comprising a discharge box which moves on the base and passes through the drill rod, a positioning wheel which rotates on the discharge box and contacts and positions the drill rod, a closing rod which reciprocates on the top of the positioning wheel, a transition pipe which is located on the outside of the closing rod is provided on the discharge box, a discharge pipe which extends to the inside of the discharge box is connected to the bottom of the transition pipe, and the inner wall of the discharge pipe slides in contact with the outer side of the closing rod; The material box is provided with an anti-vibration component that is evenly coated on the outside of the auxiliary drill rod. The anti-vibration component includes a discharge pipe located inside the discharge box and connected to the discharge pipe. The discharge pipe is penetrated by a rotating shaft that rotates synchronously with the positioning wheel. A damping rod is provided on the discharge pipe for damping sliding. One end of the damping rod is installed with a closing plate located on one side of the rotating shaft. When the rotating shaft rotates, the closing plate is pushed to move. The other end of the damping rod extends to the outside of the discharge pipe, and a sealing cylinder is provided on the outside of the other end of the damping rod; the other end of the damping rod is installed on an L-shaped rod, and one end of the L-shaped rod is installed with a scraper located on one side of the drill rod.

[0006] Preferably, the base is provided with horizontal and vertical slide rails, and the discharge box moves on the base via slide rails.

[0007] Preferably, the positioning wheel rotates on the discharge box, and a reciprocating screw is installed on the top of the positioning wheel.

[0008] Preferably, a reciprocating thread is provided on the outer side of the reciprocating screw rod, and one end of the closing rod moves reciprocatingly on the reciprocating thread on the outer side of the reciprocating screw rod through a connecting rod.

[0009] Preferably, the inner diameter of the feed tube is designed to match the diameter of the closing rod, and the bottom end of the feed tube is connected to the discharge tube, and the discharge tube is located inside the discharge box.

[0010] Preferably, a positioning ring for limiting the position of the drill rod is installed on the discharge box, and the discharge port of the discharge pipe is located between the two positioning rings.

[0011] Preferably, a push block is installed on the outer side of the rotating shaft, and the push block pushes the closing plate to move as the rotating shaft rotates.

[0012] Preferably, a piston rod is installed at one end of the damping rod extending to the outside of the discharge pipe, and one end of the piston rod extends into the interior of the sealing cylinder.

[0013] Preferably, a limiting groove for the sliding of the L-shaped rod is provided at the bottom of the discharge box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention seals the feed pipe after the sealing rod enters it, so that the lubricant inside the transition pipe cannot enter the discharge box. Therefore, the rotation time of the positioning wheel can be controlled according to the distance the drill rod rotates and moves downward, thereby controlling the amount of lubricant entering the discharge box. Therefore, the amount of lubricant can be quantitatively designed according to the downward movement length of the drill rod. On the one hand, it can prevent excessive lubricant from being applied to the drill rod surface, thereby affecting the anti-vibration and deflection effect. On the other hand, it can save the use of lubricant, saving resources and costs.

[0016] 2. According to the present invention, after the closing rod is moved out of the interior of the discharge pipe, the lubricant inside the transition pipe will enter the interior of the discharge pipe through the discharge pipe. During this process, the positioning wheel drives the rotating shaft to rotate, and the pushing block is driven to rotate during the rotation of the rotating shaft. After the pushing block rotates to a certain position, it will push the closing plate to move. After the closing plate moves, the gap between the closing plate and the rotating shaft will become larger, and the lubricant will pass through the gap and be smeared on the surface of the drill rod through the discharge port of the discharge pipe; thus, the lubricant is automatically applied to the surface of the drill rod, which can save manpower and improve work efficiency.

[0017] 3. The present invention can automatically adjust the size of the gap between the closing plate and the rotating shaft according to the rotation speed of the drill rod, and then automatically increase or reduce the use of lubricant according to the rotation speed of the drill rod. On the one hand, it can automatically apply a suitable amount of lubricant to the surface of the drill rod to avoid errors in the amount of lubricant applied manually. On the other hand, applying a suitable amount of lubricant can reduce its vibration and avoid drilling deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The present invention provides a device for preventing vibration and displacement of geological exploration drilling equipment, including a base 1 of movable design. Through the movable design of the base 1, the position of the discharge box 21 can be adjusted according to actual conditions, and the staff does not need to carry the entire device, thereby improving its practicality and saving manpower; a quantity control component 2 is provided on the base 1, and the quantity control component 2 includes a discharge box 21 that moves on the base 1 and penetrates the drill rod, a positioning wheel 22 that contacts the drill rod and positions it is rotated on the discharge box 21, a closing rod 27 is reciprocatingly moved on the top of the positioning wheel 22, and a transition pipe 24 is provided on the discharge box 21, which is located outside the closing rod 27, and the bottom of the transition pipe 24 is connected to an extension To the discharge pipe 26 inside the discharge box 21, the inner wall of the discharge pipe 26 fits and slides with the outer side of the closing rod 27; the base 1 is provided with horizontal and vertical slide rails, the discharge box 21 moves on the base 1 through the slide, the positioning wheel 22 rotates on the discharge box 21, and a reciprocating screw rod 23 is installed on the top of the positioning wheel 22, which is characterized in that a reciprocating thread is provided on the outer side of the reciprocating screw rod 23, and one end of the closing rod 27 reciprocates on the reciprocating thread on the outer side of the reciprocating screw rod 23 through a connecting rod. The inner diameter of the discharge pipe 26 is adapted to the diameter of the closing rod 27, and the bottom end of the discharge pipe 26 is connected to the discharge pipe 31, and the discharge pipe 31 is located inside the discharge box 21;

[0028] See Figures 1 to 5 As shown, when drilling is required during geological exploration, the drill rod is driven to rotate by the power source after passing through the discharge box 21. Since the positioning wheels 22 are arranged around the drill rod in multiple numbers, the drilling angle can be corrected when the drill rod is working, thereby improving the accuracy of drilling. In addition, when the drill rod rotates, the positioning wheel 22 is driven to rotate by friction, and the positioning wheel 22 drives the reciprocating screw rod 23 to rotate. The outer side of the reciprocating screw rod 23 is provided with a reciprocating thread. One end of the closing rod 27 moves back and forth on the reciprocating thread on the outer side of the reciprocating screw rod 23 through a connecting rod. Therefore, the closing rod 27 can be moved inside the discharge pipe 26 through the reciprocating screw rod 23. When the closing rod 27 moves out of the discharge pipe 26, the outside The prepared lubricant can enter the interior of the feed pipe 26 through the transition pipe 24, and then enter the interior of the discharge box 21 through the feed pipe 26; after entering the interior of the feed pipe 26 through the closing rod 27, it is sealed, and the lubricant inside the transition pipe 24 cannot enter the interior of the discharge box 21; thereby, the rotation time of the positioning wheel 22 can be controlled according to the distance the drill rod rotates and moves downward, thereby controlling the amount of lubricant entering the discharge box 21; thereby, the amount of lubricant can be quantitatively designed according to the downward movement length of the drill rod; on the one hand, it can avoid excessive lubricant being smeared on the surface of the drill rod, affecting its drilling work, and on the other hand, it can save the use of lubricant, save resources and costs.

[0029] The discharge box 21 is provided with an anti-vibration component 3 evenly coated on the outside of the auxiliary drill rod. The anti-vibration component 3 includes a discharge pipe 31 located inside the discharge box 21 and connected to the discharge pipe 26. The discharge pipe 31 is penetrated by a rotating shaft 33 that rotates synchronously with the positioning wheel 22. A damping rod 39 is provided on the discharge pipe 31 for damping sliding. One end of the damping rod 39 is installed with a closing plate 310 located on one side of the rotating shaft 33. When the rotating shaft 33 rotates, the closing plate 310 is pushed to move. The other end of the damping rod 39 extends to the outside of the discharge pipe 31, and the other end of the damping rod 39 is covered with a sealing cylinder 35 on the outside. An L-shaped rod 34 is installed at the other end, and a scraper 36 located on one side of the drill rod is installed at one end of the L-shaped rod 34. A positioning ring 32 for limiting the position of the drill rod is installed on the discharge box 21. The discharge port of the discharge pipe 31 is located between the two positioning rings 32. A push block 38 is installed on the outer side of the rotating shaft 33. The push block 38 pushes the closing plate 310 to move as the rotating shaft 33 rotates. A piston rod 37 is installed at one end of the damping rod 39 extending to the outside of the discharge pipe 31. One end of the piston rod 37 extends into the interior of the sealing cylinder 35. A limiting groove for the sliding of the L-shaped rod 34 is opened at the bottom of the discharge box 21;

[0030] See Figures 3 to 7 As shown, after the closing rod 27 moves out of the interior of the discharge pipe 26, the lubricant inside the transition pipe 24 will enter the interior of the discharge pipe 31 through the discharge pipe 26. During this process, the positioning wheel 22 drives the rotating shaft 33 to rotate. During the rotation of the rotating shaft 33, the pushing block 38 is driven to rotate. After the pushing block 38 rotates to a certain position, it pushes the closing plate 310 to move. After the closing plate 310 moves, the gap between the closing plate 310 and the rotating shaft 33 will become larger. As a result, the lubricant passes through the gap and is applied to the surface of the drill rod through the discharge port of the discharge pipe 31. In this way, the lubricant is automatically applied to the surface of the drill rod, which can save manpower and improve work efficiency.

[0031] The cam 37 is pressed against the piston rod 37 and the piston rod 37 is pressed against the piston rod 37. The cam 37 is pressed against the piston rod 37 and the piston rod 37 is pressed against the piston rod 37. The contact frequency between the closing plate 310 and the closing plate 310 is high. Therefore, when the closing plate 310 has not yet been completely reset, the push block 38 pushes the closing plate 310 to move again, thereby maintaining a large gap between the closing plate 310 and the rotating shaft 33. As a result, the lubricant can be continuously output at a certain amount during the process of the drill rod rotating at a high speed. In addition, the size of the gap between the closing plate 310 and the rotating shaft 33 can be automatically adjusted according to the rotation speed of the drill rod, and the use of lubricant can be automatically increased or decreased according to the rotation speed of the drill rod. On the one hand, the appropriate amount of lubricant can be automatically applied to the surface of the drill rod to avoid errors in the amount of lubricant applied manually. On the other hand, applying the appropriate amount of lubricant can reduce its vibration and avoid drilling deviation.

[0032] In addition, when the piston rod 37 moves, the piston rod 37 drives the L-shaped rod 34 to move, and the L-shaped rod 34 drives the scraper 36 to move, thereby automatically adjusting the distance between the scraper 36 and the drill rod. Therefore, the thickness of the lubricant on the outside of the drill rod can be controlled by the scraper 36. On the one hand, the excess lubricant on the outside of the drill rod can be scraped off, and on the other hand, the lubricant on the outside of the drill rod can be evenly applied, further improving the effect of reducing its vibration and avoiding drilling deviation.

[0033] In addition, the two positioning rings 32 are designed to be located up and down and on the same axis, so as to achieve a limited positioning effect on the drill rod.

[0034] Working principle: During drilling, after the drill penetrates the discharge box 21, it is driven to rotate by the power source. Since the positioning wheels 22 are arranged in multiple numbers around the drill rod, the drilling angle can be assisted to be correct when the drill rod is working, thereby improving the accuracy of drilling. In addition, when the drill rod rotates, the positioning wheel 22 is driven to rotate by friction, and the positioning wheel 22 drives the reciprocating screw rod 23 to rotate. A reciprocating thread is provided on the outside of the reciprocating screw rod 23. One end of the closing rod 27 moves back and forth on the reciprocating thread on the outside of the reciprocating screw rod 23 through a connecting rod. Therefore, through the reciprocating screw rod 23, the closing rod 27 can move inside the discharge pipe 26. After the closing rod 27 moves out of the interior of the discharge pipe 26, the lubricant inside the transition pipe 24 will enter the interior of the discharge pipe 31 through the discharge pipe 26. During this process, the positioning wheel 22 drives the rotating shaft 33 to rotate. During the rotation of the rotating shaft 33, the push block 38 is driven to rotate. After the push block 38 rotates to a certain position, it will push the closing plate 310 to move. After the closing plate 310 moves, the gap between the closing plate 310 and the rotating shaft 33 will become larger, so that the lubricant passes through the gap and is smeared onto the surface of the drill rod through the discharge port of the discharge pipe 31; thereby, the lubricant is automatically applied to the surface of the drill rod, which can save manpower and improve work efficiency.

[0035] When the locking cam 37 is in the closed position, the locking cam 37 is in the closed position, and the locking cam 37 is in the closed position, so that the locking cam 37 is locked.

[0036] In addition, when the piston rod 37 moves, the piston rod 37 drives the L-shaped rod 34 to move, and the L-shaped rod 34 drives the scraper 36 to move, thereby automatically adjusting the distance between the scraper 36 and the drill rod. Therefore, the thickness of the lubricant on the outside of the drill rod can be controlled by the scraper 36. On the one hand, the excess lubricant on the outside of the drill rod can be scraped off, and on the other hand, the lubricant on the outside of the drill rod can be evenly applied.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
