Description

Technical Field

[0001] The invention belongs to the technical field of geological survey, and in particular relates to a drilling device used for environmental geological survey. Background Art

[0002] Geological exploration is the abbreviation of geological exploration work. In a broad sense, it can be generally understood as a synonym for geological work. It is a survey and research work with different focuses on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area according to the needs of economic construction, national defense construction, and scientific and technological development. There are different geological exploration work according to different purposes. For example, mineral geological exploration with the main purpose of finding and evaluating minerals, hydrogeological exploration with the main purpose of finding and developing groundwater, and engineering geological exploration with the purpose of identifying the geological conditions of engineering areas such as railways, bridges, reservoirs, and dam sites. Drilling is one of the necessary technical means of geological exploration. The drilling methods include impact drilling and rotary drilling. The latter is mainly used in engineering geological exploration. The drill rod is one of the important drilling tools required for drilling. The ends of the drill rod can be connected by threads. When the drilling device on the surface inserts the drill rod, the bottom end of the drill rod is usually threadedly connected to the top of the previous drill rod that has entered the rock and soil, or the top of the drill rod is directly threadedly connected to the drilling equipment, so that the drill rod is finally vertically inserted into the rock and soil. Then the drilling equipment needs to rotate in the opposite direction and then disengage from the drill rod so as to insert the next drill rod. This operation method is more cumbersome, which affects work efficiency and the life of the drilling equipment. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a drilling device for environmental geological survey, which solves the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drilling device for environmental geological survey, comprising a base frame and a guide rod, a mounting plate is sleeved on the surface of the guide rod, a motor I is fixedly installed inside the mounting plate, a circular plate is fixedly connected to the output end of the motor I, a support rod is fixedly connected to the lower surface of the mounting plate, a fixing plate is fixedly connected to one end of the support rod, an L-shaped rod is fixedly connected to the lower surface of the circular plate, a through groove is provided on the upper surface of the fixing plate, a limit seat is slidably installed inside the through groove, a fixing rod I is installed through the inside of the limit seat, and a clamping plate is fixedly connected to the bottom end of the fixing rod I;

[0005] A fixing rod II is fixedly installed on the upper surface of the fixing plate, an arc-shaped steel sheet is fixedly connected to the surface of the fixing rod II, an elastic rope is fixedly connected to one side of the L-shaped rod, a notch is provided on the surface of the fixing plate, a fixing frame I is fixedly installed on the upper surface of the base frame, a tilting rod is fixedly connected to the upper surface of the fixing frame I, and a groove is provided on the upper surface of the tilting rod.

[0006] Preferably, a fixing frame II is fixedly mounted on the upper surface of the base frame, a motor II is fixedly mounted inside the fixing frame II, and a lead screw is fixedly connected to the output end of the motor II.

[0007] Preferably, there are three groups of through slots, each group of through slots consists of two narrow slots and one wide slot, the limiting seat vertically penetrates the narrow slots, and the fixing rod I vertically penetrates the wide slot.

[0008] Preferably, two ends of the elastic rope are respectively connected to the L-shaped rod and the notch on the fixing plate, and the position of the notch coincides with the position of the tilting rod.

[0009] Preferably, the inner wall of the clamping plate is fixedly connected with convex strips, and the convex strips are arranged in a circular arc array.

[0010] Preferably, there are two guide rods which are symmetrically mounted on the upper surface of the base frame, and the bottom end of the screw rod is rotatably connected to the base frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The drilling device for environmental geological survey is provided with an L-shaped rod, which can contact and move the fixed rod I to move by counterclockwise rotation. The fixed rod I cooperates with the clamping plate. When the fixed rod I is driven by the L-shaped rod, it can drive the three clamping plates to move inwards and approach each other at the same time, so that the top of the drill rod can be clamped and fixed, replacing the threaded connection with the drill rod. The convex strips on the inner wall of the clamping plate can increase the friction when contacting the drill rod, thereby preventing the drill rod from being unstable. By providing an arc-shaped steel sheet, the fixed rod I moved by the L-shaped rod will contact the arc-shaped steel sheet, and the force of the L-shaped rod is greater than the toughness of the arc-shaped steel sheet. Therefore, further displacement of fixing rod I will squeeze the arc-shaped steel sheet to make it bend. After the drill rod is completely fixed, the circular plate will drive the drill rod to rotate through the L-shaped rod, fixing rod I and the clamping plate. In addition, when the L-shaped rod drives fixing rod I, one side of it will pull the elastic rope to make the elastic rope taut. When the mounting plate and the parts connected thereto move downward as a whole through the elastic rope cooperating with the tilting rod, the tilting rod will intercept the taut elastic rope through the notch, which is conducive to pulling back the L-shaped rod with one end of the elastic rope. At this time, the arc-shaped steel sheet rebounds and pushes the fixing rod I back, thereby causing the clamping plate to immediately loosen the drill rod and detach from the drill rod.

[0013] 2. The drilling device for environmental geological survey is provided with a motor I, whose output end can drive the circular plate and the L-shaped rod to rotate counterclockwise, which is conducive to clamping and fixing the drill rod. The motor I will drive the fixed drill rod to rotate through the clamping plate, which is conducive to easily screwing the drill rod into the rock and soil. By opening a through groove, which is arc-shaped, the path of the fixed rod I is arc-shaped, which is conducive to reducing the angle change caused by the horizontal movement of the clamping plate, thereby making the area of ​​the clamping plate contacting the drill rod larger and the clamping more firmly.

[0014] 3. The drilling device for environmental geological survey is provided with a motor II, whose output end can drive the screw to rotate. The surface of the screw is threadedly connected to the mounting plate. Therefore, the screw rotation can drive the mounting plate to move downward through the force, so that the elastic rope is close to the tilting rod. Similarly, when the output end of motor II drives the screw to reverse, it will drive the mounting plate to move up and reset. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-7 The present invention provides the following technical solutions: a drilling device for environmental geological survey, comprising a base frame 1 and a guide rod 2, a mounting plate 3 is sleeved on the surface of the guide rod 2, a motor Ⅰ4 is fixedly installed inside the mounting plate 3, a circular plate 5 is fixedly connected to the output end of the motor Ⅰ4, a support rod 6 is fixedly connected to the lower surface of the mounting plate 3, a fixing plate 7 is fixedly connected to one end of the support rod 6, an L-shaped rod 8 is fixedly connected to the lower surface of the circular plate 5, a through groove 9 is provided on the upper surface of the fixing plate 7, a limited position seat 10 is slidably installed inside the through groove 9, a fixing rod Ⅰ11 is installed through the inside of the limiting seat 10, and a clamping plate 12 is fixedly connected to the bottom end of the fixing rod Ⅰ11;

[0026] A fixing rod II 13 is fixedly installed on the upper surface of the fixing plate 7, and an arc-shaped steel sheet 14 is fixedly connected to the surface of the fixing rod II 13. An elastic rope 15 is fixedly connected to one side of the L-shaped rod 8. A notch 16 is provided on the surface of the fixing plate 7. A fixing frame I 17 is fixedly installed on the upper surface of the base frame 1. A tilting rod 18 is fixedly connected to the upper surface of the fixing frame I 17. A groove 19 is provided on the upper surface of the tilting rod 18.

[0027] In this embodiment, an L-shaped rod 8 is provided, and its counterclockwise rotation can contact and move the fixing rod Ⅰ11 to cause displacement. The fixing rod Ⅰ11 cooperates with the clamping plate 12. When the fixing rod Ⅰ11 is driven by the L-shaped rod 8, it can drive the three clamping plates 12 to move inward and close to each other at the same time, so that the top of the drill rod can be clamped and fixed, replacing the threaded connection with the drill rod. The convex strips on the inner wall of the clamping plate 12 can increase the friction when contacting the drill rod, thereby preventing the drill rod from being unstable. By providing an arc-shaped steel sheet 14, the fixing rod Ⅰ11 moved by the L-shaped rod 8 will contact the arc-shaped steel sheet 14. The force of the L-shaped rod 8 is greater than the toughness of the arc-shaped steel sheet 14. Therefore, further displacement of the fixing rod Ⅰ11 will squeeze the arc-shaped steel sheet 14 to make it bend. After the drill rod is completely fixed, the circular The plate 5 will drive the drill rod to rotate through the L-shaped rod 8, the fixing rod Ⅰ11 and the clamping plate 12. In addition, when the L-shaped rod 8 drives the fixing rod Ⅰ11, one side of the L-shaped rod 8 will pull the elastic rope 15 to make the elastic rope 15 taut. When the mounting plate 3 and the parts connected thereto are moved downward as a whole through the elastic rope 15 cooperating with the tilting rod 18, the tilting rod 18 will intercept the taut elastic rope 15 through the notch 16. The groove 19 prevents the tilting rod 18 from slipping when intercepting the elastic rope 15, which is conducive to one end of the elastic rope 15 pulling back the L-shaped rod 8. At this time, the arc-shaped steel sheet 14 rebounds and pushes the fixing rod Ⅰ11 back, thereby causing the clamping plate 12 to immediately release the drill rod, thereby disengaging from the drill rod. The motor Ⅰ4 is provided, and its output end can drive the circular plate 5 and the L-shaped rod 8 to rotate counterclockwise. , which is conducive to clamping and fixing the drill rod. The motor Ⅰ4 will drive the fixed drill rod to rotate through the clamping plate 12, which is conducive to easily screwing the drill rod into the rock and soil. By opening a through groove 9, which is arc-shaped, the path of the fixing rod Ⅰ11 is arc-shaped, which is conducive to reducing the angle change of the clamping plate 12 due to horizontal movement, thereby making the area of ​​the clamping plate 12 contacting the drill rod larger and the clamping more firmly. By providing a motor Ⅱ21, its output end can drive the screw rod 22 to rotate. The surface of the screw rod 22 is threadedly connected to the mounting plate 3. Therefore, the rotation of the screw rod 22 can drive the mounting plate 3 to move downward through the force, so that the elastic rope 15 is close to the tilting rod 18. Similarly, when the output end of the motor Ⅱ21 drives the screw rod 22 to reverse, it will drive the mounting plate 3 to move upward. Reset, the upper surface of the base frame 1 is fixedly installed with a fixing frame II 20, and the interior of the fixing frame II 20 is fixedly installed with a motor II 21, and the output end of the motor II 21 is fixedly connected with a screw rod 22. The fixing frame II 20 is convenient for the installation of the motor II 21, provides an installation position for the motor II 21, and enhances the running stability of the motor II 21. The through slots 9 are arranged in three groups, each group of through slots 9 is composed of two narrow slots and one wide slot, the limiting seat 10 vertically penetrates the narrow slot, and the fixing rod I 11 vertically penetrates the wide slot, so that the limiting seat 10 cooperates with the narrow slot to limit the fixing rod I 11 to prevent it from changing its angle and avoid increasing the angle difference between the three clamping plates 12. The two ends of the elastic rope 15 are respectively connected to the L-shaped rod 8 and the notch 16 on the fixing plate 7. Therefore,It is beneficial for the elastic rope 15 to be pulled into a taut state by the L-shaped rod 8. The elastic rope 15 is elastic, so it can play a buffering role. The position of the notch 16 coincides with the position of the tilting rod 18. When the elastic rope 15 approaches the tilting rod 18, the tilting rod 18 can intercept and limit the elastic rope 15 through the notch 16, which is beneficial for pulling back the L-shaped rod 8. The inner wall of the clamping plate 12 is fixedly connected with a convex strip, and the convex strip is arranged in a circular arc array, which is beneficial for improving the friction between the clamping plate 12 and the drill rod when it contacts, and it is easier to drive the drill rod to rotate. There are two guide rods 2 and they are symmetrically installed on the upper surface of the base frame 1, so that the guide rod 2 vertically penetrates the mounting plate 3, and the mounting plate 3 is displaced in the vertical direction of the guide rod 2, so that the guide rod 2 limits it to prevent the mounting plate 3 from tilting. The bottom end of the screw rod 22 is rotatably connected to the base frame 1, so that the base frame 1 can limit its bottom end without affecting the rotation of the screw rod 22.

[0028] The working principle and use process of the present invention are as follows: when the present invention is used, the bottom end of a drill rod is firstly threadedly connected with the top end of the previous drill rod that has entered the rock and soil, and then the motor II 21 is controlled to start driving the screw rod 22 to rotate. The screw rod 22 rotates to drive the mounting plate 3 to move downward through the force, and stops when the horizontal position of the clamping plate 12 coincides with the position of the top end of the drill rod. Then the motor I4 is controlled to start driving the circular plate 5 and the L-shaped rod 8 to rotate counterclockwise. The counterclockwise rotation of the L-shaped rod 8 can contact and move the fixing rod I11 to displace. When the fixing rod I11 is driven by the L-shaped rod 8, it can drive the three clamping plates 12 to move inward at the same time and approach each other, thereby clamping and fixing the top end of the drill rod. The fixing rod I11 moved by the L-shaped rod 8 will contact the arc-shaped steel sheet 14. Further displacement of the fixing rod I11 will squeeze the arc-shaped steel sheet 14 to make it bend. After the drill rod is completely fixed, the motor Ⅰ4 drives the drill rod to rotate through the circular plate 5, L-shaped rod 8, fixed rod Ⅰ11 and clamping plate 12. After the L-shaped rod 8 drives the fixed rod Ⅰ11, one side of the L-shaped rod 8 will pull the elastic rope 15 to make the elastic rope 15 taut, and then start the motor Ⅱ21 again. At this time, the downward pressure of the mounting plate 3 cooperates with the motor Ⅰ4 to drive the drill rod to rotate, and the drill rod will quickly enter the rock and soil. When the elastic rope 15 contacts the tilting rod 18, the mounting plate 3 continues to move downward, and the tilting rod 18 will intercept the taut elastic rope 15 through the notch 16. One end of the elastic rope 15 pulls back the L-shaped rod 8. At this time, the arc-shaped steel sheet 14 rebounds and pushes the fixed rod Ⅰ11 back, thereby causing the clamping plate 12 to immediately release the drill rod, thereby detaching from the drill rod. Finally, the motor Ⅱ21 is controlled to reverse, driving the mounting plate 3 to move up and reset, and so on to install the next drill rod. Among them, the input ends of the electrical equipment in this device are all electrically connected to the external power supply.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
