Abstract
Description
Technical Field
[0001] This invention relates to the field of geological exploration technology, specifically to a geological exploration device for engineering applications. Background Technology
[0002] In engineering geological investigation and soil compaction construction, soil compaction testing is a technical means to obtain the compaction characteristics of the fill material and evaluate the compaction quality. To obtain accurate test data, soil samples must be obtained through field sampling and sent to a laboratory for a series of tests, including light compaction tests and heavy compaction tests. During field sampling, percussion soil sampling rigs are often used to efficiently and non-destructively collect deep or shallow soil samples.
[0003] For example, patent CN118980542B discloses a soil sampling device for soil compaction testing, including an impact head with multiple shock-absorbing handles fixedly installed on it. A sampling outer tube is connected to the impact head via a connecting mechanism, and a sampling toothed cylinder is threaded onto the outer tube. Two spur gears and two reversible gear rings are installed inside the outer tube via a rotating mechanism. The advantages are: by repeatedly cutting the sampled soil, it can be quickly layered; after layering, the soil is quickly packaged with plastic film, ensuring the integrity of the soil sampling data; and finally, the layered sampled soil is quickly removed using a splicing installation method, ensuring the integrity of the internal sampled soil and improving the accuracy of soil compaction test data.
[0004] The aforementioned impact soil sampling drill still has certain shortcomings: After sampling deep soil layers (typically 8-10 meters), percussion soil sampling rigs need to retrieve the drill rod from the formation. However, due to friction and soil adhesion in deep soil, the drill rod is difficult to move, making manual retrieval extremely challenging. Therefore, hydraulic pipe pullers are commonly used to assist in the operation, applying vertical pulling force through a hydraulic system to retrieve the drill rod. However, this reliance on external equipment has significant drawbacks: firstly, the purchase, maintenance, and energy consumption of hydraulic pipe pullers significantly increase exploration costs; secondly, geological exploration teams need to carry heavy hydraulic equipment, increasing the workload for personnel and hindering the improvement of geological exploration efficiency. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a geological exploration device for engineering applications that uses an impact head to pull out drill rods, eliminating the need for additional pipe pullers, thus reducing both costs and personnel workload.

[0007] Furthermore, the mounting assembly includes a fixed frame, hook blocks, a connecting plate, a mounting plate, an impact plate, and fixing bolts. The opposing surfaces of the two long sliders are each fixedly connected to symmetrically arranged fixed frames. A set of hook blocks is fixedly connected to the upper end of the opposing surfaces of the two fixed frames. The hook blocks match the handle of the impact head. Below the hook blocks is a mounting plate fixedly connected to the fixed frame. The impact plate is slidably connected to the upper part of the mounting plate. Fixing bolts are slidably connected to both ends of the impact plate. One end of each fixing bolt passes through the impact plate and is slidably connected to the mounting plate. A connecting plate is located at the upper end between the two fixed frames, and both ends of the connecting plate are fixedly connected to the two hook blocks respectively.
[0008] Furthermore, the lifting assembly includes a lifting plate, a fixing plate, and a positioning bolt. The lifting plate is fixedly connected between the two short sliders. The fixing plate is rotatably connected to the side of the lifting plate away from the connecting frame. A positioning bolt is provided at one end of the lifting plate. One end of the positioning bolt passes through the fixing plate and is threaded to the lower end of the lifting plate. A circular hole is provided in the middle of the lifting plate and the fixing plate. A set of clamps is installed at the circular hole.
[0009] Furthermore, the traction transmission assembly includes a fixed pulley and a traction rope. The fixed pulley is rotatably connected to the upper end of the side plate near the connecting frame. The traction rope is fixedly connected to the top of the fixed frame. The other end of the traction rope passes over the top of the fixed pulley and is fixedly connected to the lifting plate.
[0010] Furthermore, a communicating vessel is fixedly connected inside the side plate. A first piston rod is slidably connected to one end of the communicating vessel near the long slider, and a second piston rod is slidably connected to one end of the communicating vessel near the short slider. The first piston rod is fixedly connected to the long slider, and the second piston rod is fixedly connected to the short slider.
[0011] Furthermore, the fixing component includes a positioning post, a pressing elastic element, a positioning slider, and an insert plate. Positioning grooves are provided on both sides of the connecting frame near the lifting plate. A positioning post is fixedly connected inside the positioning groove. A positioning slider is slidably connected to the lower end of the positioning post. A pressing elastic element is sleeved on the upper end of the positioning post.

A turntable is provided on the side of one of the gears away from the rotating shaft. The turntable is fixed to the rotating shaft.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When this type of geological exploration equipment needs to pull the drill rod out of the soil, it is only necessary to first move the side plate and connecting frame away from the drill rod, then rotate the side plate and connecting frame and push them back to their original positions to align the drill rod with the lifting assembly. Then connect the drill rod to the lifting assembly and the impact head to the installation assembly. The impact head can then be activated, and the impact force of the impact head will drive the installation assembly to move down. Driven by the traction transmission assembly, the lifting assembly will pull the drill rod out of the soil. The whole process does not require the use of an additional pipe puller, which can reduce costs and reduce personnel workload.
[0014] 2. After the connecting frame returns to its original position, the connecting frame of this type of engineering geological exploration equipment can be fixed by the fixing component to prevent displacement of the connecting frame, which could lead to misalignment between the lifting component or the impact head and the drill rod, resulting in equipment damage.
[0015] 3. When the impact head of this type of engineering geological exploration equipment is moved to the lower end of the entire device, if it is necessary to move the impact head to the upper end of the entire device, the turntable can be rotated, and the gear will be driven to rotate through the rotating shaft. The gear will then push the rack plate to move, allowing the impact head to move to the upper end of the entire device. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0019] Please see Figures 1 to 13An engineering geological exploration device includes an impact head 1 and a drill rod 36. A base plate 2 is provided below the impact head 1. A rotating groove 5 is provided in the middle of the top of the base plate 2. A rotating block 6 is slidably connected inside the rotating groove 5. A connecting frame 4 is fixed to the top of the rotating block 6. Side plates 3 are symmetrically arranged and fixed to both sides of the connecting frame 4. A sliding groove 13 is provided on both sides of the side plate 3. A sliding rod 14 is fixed inside the sliding groove 13. A long slider 15 is slidably connected inside one sliding groove 13, and a short slider 22 is slidably connected inside the other sliding groove 13. An installation assembly is fixed between the two long sliders 15. The impact head 1 is installed inside the installation assembly. A lifting assembly is fixed between the two short sliders 22. A slip 26 is installed in the middle of the lifting assembly. A traction transmission assembly is installed on the side plate 3. A fixing assembly is connected to the side of the connecting frame 4 near the lifting assembly.
[0020] In the engineering geological exploration equipment of this invention, during sampling, the drill rod 36 is simply installed on the output end below the impact head 1. Then, the impact head 1 is activated to drive the drill rod 36 into the soil for sampling. After sampling, when it is necessary to pull the drill rod 36 out of the soil, the fixing assembly can be disassembled first. Then, the side plate 3 and connecting frame 4 are pushed away from the drill rod 36. Next, the side plate 3 and connecting frame 4 are rotated 180° to bring the lifting assembly closer to the drill rod 36. Then, the side plate 3 and connecting frame 4 are pushed towards the drill rod 36 to align the lifting assembly with the drill rod 36. Finally, the lifting assembly is pulled to fit over the drill rod 36. The 26 clamp is placed in the gap between the lifting assembly and the drill rod 36. Then, the impact head 1 is connected to the mounting assembly. The impact head 1 is then activated, and the impact force of the impact head 1 drives the mounting assembly to move downward. Under the pull of the traction transmission assembly, the lifting assembly drives the drill rod 36 to move upward, thereby pulling the drill rod 36 out of the soil. The whole process does not require the use of an additional pipe puller, which can reduce costs and reduce personnel load. In addition, the structure of the impact head 1 in this invention is similar to the structure of a soil sampling device for soil compaction testing disclosed in patent patent authorization announcement number CN118980542B, so it will not be described in detail here.
[0021] As a preferred embodiment of the present invention, the mounting assembly includes a fixed frame 16, hook blocks 17, a connecting plate 18, a mounting plate 19, an impact plate 20, and fixing bolts 21. Two long sliders 15 are each fixedly connected to symmetrically arranged fixed frames 16 on their opposite sides. A set of hook blocks 17 is fixedly connected to the upper end of the opposite sides of each of the two fixed frames 16. The hook blocks 17 match the handle of the impact head 1. Below the hook blocks 17, a mounting plate 19 is fixedly connected to the fixed frame 16. The impact plate 20 is slidably connected to the upper part of the mounting plate 19. Fixing bolts 21 are slidably connected to both ends of the impact plate 20. One end of the fixing bolt 21 passes through the impact plate 20 and is slidably connected to the mounting plate 19. A connecting plate 18 is located at the upper end between the two fixed frames 16, and both ends of the connecting plate 18 are fixedly connected to the two hook blocks 17 respectively.
[0022] Specifically, the impact head 1 is placed on the hook block 17, and after the handle of the impact head 1 is inserted into the hook block 17, there is still a certain amount of space inside the hook block 17, so that the impact head 1 can move up and down to a certain extent without directly detaching from the hook block 17 and causing the impact head 1 to fall and be damaged, so that the impact head 1 can work normally. Before pulling out the drill rod 36, the impact plate 20 needs to be installed below the impact head 1. During installation, simply raise the impact head 1 a certain distance, then insert the impact plate 20 between the two mounting plates 19, then release the impact head 1, and the output end below the impact head 1 will fall into the groove position on the top of the impact plate 20. Then insert the fixing bolt 21 into the mounting plate 19 and tighten the fixing bolt 21 to complete the installation.
[0023] As a preferred embodiment of the present invention, the lifting assembly includes a lifting plate 23, a fixing plate 24, and a positioning bolt 25. The lifting plate 23 is fixedly connected between two short sliders 22. The fixing plate 24 is rotatably connected to the side of the lifting plate 23 away from the connecting frame 4. A positioning bolt 25 is provided at one end of the lifting plate 23. One end of the positioning bolt 25 passes through the fixing plate 24 and is threadedly connected to the lower end of the lifting plate 23. A round hole is provided in the middle of the lifting plate 23 and the fixing plate 24. A set of clips 26 are installed at the round hole.
[0024] Specifically, before pushing the connecting frame 4 toward the drill rod 36, the fixing plate 24 is opened to prevent the drill rod 36 from hitting the fixing plate 24, and then the connecting frame 4 is moved. After the lifting plate 23 is aligned with the drill rod 36, the lifting plate 23 is pulled to allow the drill rod 36 to pass through the round hole on the lifting plate 23. Then the fixing plate 24 is rotated to lock the fixing plate 24 and the lifting plate 23 together. Then the positioning bolt 25 is inserted into the end of the lifting plate 23 and the positioning bolt 25 is tightened. Finally, the clip 26 is placed in the gap between the drill rod 36 and the round hole. The whole process is simple, convenient and easy to operate.
[0025] As a preferred technical solution of the present invention, the traction transmission assembly includes a fixed pulley 30 and a traction rope 31. The fixed pulley 30 is rotatably connected to the upper end of the side plate 3 near the connecting frame 4. The traction rope 31 is fixedly connected to the top of the fixed frame 16. The other end of the traction rope 31 passes over the top of the fixed pulley 30 and is fixedly connected to the lifting plate 23.
[0026] As a preferred technical solution of the present invention, a communicating vessel 29 is fixedly connected inside the side plate 3. A first piston rod 27 is slidably connected to one end of the communicating vessel 29 near the long slider 15, and a second piston rod 28 is slidably connected to one end of the communicating vessel 29 near the short slider 22. The first piston rod 27 is fixedly connected to the long slider 15, and the second piston rod 28 is fixedly connected to the short slider 22.
[0027] Specifically, when the impact head 1 is working, the impact force it generates will push the impact plate 20 downward. As the impact plate 20 moves downward, it will also cause the fixed frame 16 to move downward. The fixed frame 16 will then pull the lifting plate 23 upward through the traction rope 31, thereby pulling the drill rod 36 out of the soil. During the downward movement of the fixed frame 16, it will also cause the long slider 15 to move downward. The long slider 15 will then push the first piston rod 27 downward, thereby squeezing the liquid inside the communicating vessel 29. After being pressurized, the liquid will push the second piston rod 28 upward. The second piston rod 28 will then drive the short slider 22 upward, which in turn will drive the lifting plate 23 upward. Since the communicating vessel 29 is filled with liquid, and hydraulic transmission is more uniform and stable than mechanical transmission, the impact will be smaller and the response speed will be faster. Therefore, the impact force of the impact head 1 on the drill rod 36 can be reduced, making the extraction process of the drill rod 36 more stable.
[0028] As a preferred technical solution of the present invention, the fixing component includes a positioning post 8, a pressing elastic member 9, a positioning slider 10, and an insert plate 11. The connecting frame 4 has positioning grooves 7 on both sides of the side near the lifting plate 23. The positioning post 8 is fixedly connected inside the positioning groove 7. The lower end of the positioning post 8 is slidably connected to the positioning slider 10. The upper end of the positioning post 8 is fitted with the pressing elastic member 9. The upper end of the pressing elastic member 9 is fixedly connected to the top of the positioning groove 7. The lower end of the pressing elastic member 9 is fixedly connected to the positioning slider 10. The insert plate 11 is fixedly connected to one side of the positioning slider 10. The bottom plate 2 has slots 12 on both sides that match the insert plate 11.
[0029] Specifically, when it is necessary to fix the connecting frame 4, simply align the insert plate 11 with the slot 12, and then, under the action of the pressing elastic member 9, the positioning slider 10 will drive the insert plate 11 to move down, thereby allowing the insert plate 11 to be inserted into the slot 12.
[0030] As a preferred technical solution of the present invention, a rotating shaft 34 is rotatably connected to the middle position of the side plate 3 and the connecting frame 4. Gears 33 are fixedly connected to both ends of the rotating shaft 34. A rack plate 32 is fixedly connected to the side of the long slider 15 away from the connecting frame 4. The gear 33 meshes with the rack plate 32. A turntable 35 is provided on the side of one of the gears 33 away from the rotating shaft 34. The turntable 35 is fixedly connected to the rotating shaft 34.
[0031] Specifically, when the impact head 1 moves to the lower end of the connecting frame 4, if it is necessary to move the impact head 1 to the upper end of the connecting frame 4, the turntable 35 can be rotated, and the gear 33 will be rotated through the rotating shaft 34. The gear 33 will then push the rack plate 32 to move, allowing the impact head 1 to move up to the upper end of the connecting frame 4.
[0032] It is worth noting that the entire drill rod 36 is composed of multiple drill rod sections connected together by threads. Each time the lifting assembly moves from the lower end of the side plate 3 to the upper end, it pulls out a section of the upper end of the entire drill rod 36. It does not pull out the entire drill rod 36 at once, but rather pulls out and disassembles it section by section. Furthermore, since the drill rod 36 is inserted into the soil under the impact force of the impact head 1, the friction between the drill rod 36 and the soil is relatively large. Therefore, after a section of the drill rod 36 is pulled out, when the lifting assembly located at the upper end of the side plate 3 is separated from the drill rod 36, the drill rod 36 will not fall back to its original position due to its own weight.
[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
