Description

Technical Field

[0001] This utility model relates to the field of geological drilling technology, and in particular to a safety protection device for geological drilling. Background Technology

[0002] Geological drilling refers to a geological engineering project that uses specific drilling machinery and techniques to obtain rock and mineral cores below the Earth's surface, providing a reliable evaluation of geological and mineral resource parameters. Drilling rigs drill downwards from the surface, creating cylindrical boreholes in the strata to identify and delineate them. Rock cores, mineral samples, and soil samples can be obtained from different depths within the borehole for analysis and research, used to determine the physical and mechanical properties and indicators of the rocks and soil layers, providing information for design requirements.

[0003] For some small drilling sampling devices, in order to reduce manufacturing costs, their structure is usually relatively simple, and the sampling tube lacks protective structure. As a result, rock fragments may be thrown during the sampling process. During the sampling process, the operator needs to stabilize the small drilling sampling device, which may cause certain injuries to the operator from the flying rock fragments. Therefore, a safety protection device for geological drilling is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a safety protection device for geological drilling, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a safety protection device for geological drilling, including a bottom support frame. Two support rods are fixedly connected to one side of the bottom support frame, and a support base is fixedly connected to the top of the two support rods. A first motor is fixedly installed on one side of the support base, and a lead screw is fixedly connected to the output end of the first motor. A T-shaped movable seat is threaded onto the outer surface of the lead screw. A second motor is fixedly installed on one side of the T-shaped movable seat, and a sampling cylinder is fixedly connected to the output end of the second motor. Two support inclined plates are fixedly connected to one side of the T-shaped movable seat. Guide rods are inserted into one side of each of the two supporting inclined plates. A connecting plate is fixedly connected to the bottom of each of the two guide rods. A protective cylinder is fixedly connected to one end of each of the two connecting plates. A compression spring is fixedly connected to the side of each of the two connecting plates near the guide rods. A through hole is provided on the top side of the protective cylinder. A buffer pad is fixedly connected to the bottom side of the protective cylinder. A vacuum suction hose is fixedly connected to the outer surface of the protective cylinder. A vacuum suction fan is fixedly connected to the end of the vacuum suction hose away from the protective cylinder. A filter box is fixedly connected to the air outlet of the vacuum suction fan through a pipe. A filter screen is fixedly connected inside the filter box.

[0007] Preferably, in any of the above embodiments, a water injection hose is fixedly connected to the outer surface of the protective cylinder, which facilitates the addition of water to the inside of the protective cylinder, thereby facilitating the cooling of the sampling cylinder.

[0008] Preferably, in any of the above embodiments, the support rod passes through the T-shaped movable seat, the T-shaped movable seat is slidably connected to the support rod, and the support rod guides the T-shaped movable seat so that the T-shaped movable seat can only move in a straight line along the direction of the support rod.

[0009] Preferably, in any of the above schemes, the center of the sampling tube and the center of the protective tube are on the same vertical plane, the outer diameter of the sampling tube is smaller than the inner diameter of the protective tube, and the outer diameter of the sampling tube is smaller than the diameter of the perforation, so as to avoid interference between the sampling tube and the protective tube during rotation and to ensure that the sampling tube rotates smoothly.

[0010] Preferably, in any of the above solutions, the bottom end of the lead screw is rotatably connected to the bottom support frame via a bearing, which supports and fixes the bottom end of the lead screw, thereby ensuring the stability of the lead screw during rotation.

[0011] Preferably, in any of the above embodiments, the guide rod has a T-shaped cross-section, a portion of which is located inside the compression spring. The end of the compression spring away from the connecting plate is fixedly connected to the supporting inclined plate, so that the compression spring can undergo elastic deformation as the connecting plate moves. Furthermore, the guide rod can prevent the compression spring from bending during the elastic deformation process.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. Through the coordinated arrangement of the first motor, lead screw, T-shaped moving seat, second motor, sampling cylinder, supporting inclined plate, guide rod, connecting plate, protective cylinder, compression spring, perforation and buffer pad, a structure is added to the outside of the sampling cylinder to protect it. This can protect the sampling cylinder while sampling, avoiding the occurrence of flying gravel during the sampling process, thereby preventing injury to the operator from the flying gravel, thus making the device relatively safe.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] like Figures 1 to 4As shown, a safety protection device for geological drilling includes a bottom support frame 1. Two support rods 2 are fixedly connected to one side of the bottom support frame 1. A support base 3 is fixedly connected to the top of the two support rods 2. A first motor 4 is fixedly installed on one side of the support base 3. A lead screw 5 is fixedly connected to the output end of the first motor 4. A T-shaped moving seat 6 is threaded onto the outer surface of the lead screw 5. A second motor 7 is fixedly installed on one side of the T-shaped moving seat 6. A sampling cylinder 8 is fixedly connected to the output end of the second motor 7. Two support inclined plates 9 are fixedly connected to one side of the T-shaped moving seat 6. The two support inclined plates 9 are symmetrically distributed about the T-shaped moving seat 6. A guide rod 10 is inserted into one side of each of the two support inclined plates 9. A connecting plate 11 is fixedly connected to the bottom end of each of the two guide rods 10. A protective cylinder 12 is fixedly connected to one end of each of the two connecting plates 11. A compression spring 13 is fixedly connected to the side of each of the two connecting plates 11 near the guide rods 10. A perforation 14 is provided on the top side of the protective cylinder 12. A buffer pad 15 is fixedly connected to the bottom side of the protective cylinder 12. The buffer pad 15 is made of rubber. The buffer pad 15 can cushion the protective cylinder 12, preventing damage to the protective cylinder 12 due to rigid connection with the ground. The buffer pad 15 also ensures a tighter fit with the ground, preventing gaps between the protective cylinder 12 and the bottom surface from causing gravel to splash out from inside the protective cylinder 12. In the case of sampling, a vacuum hose 16 is fixedly connected to the outer surface of the protective cylinder 12. A vacuum fan 17 is fixedly connected to the end of the vacuum hose 16 away from the protective cylinder 12. A filter box 18 is fixedly connected to the air outlet of the vacuum fan 17 through a pipe. A filter screen 19 is fixedly connected inside the filter box 18. During the sampling process, the first motor 4 and the second motor 7 are started. With the start of the second motor 7, the sampling cylinder 8 will rotate. With the start of the first motor 4, the lead screw 5 will rotate, thereby causing the T-shaped moving seat 6 to drive the sampling cylinder 8 and the supporting inclined plate 9 to move downward. With the movement of the supporting inclined plate 9, the guide rod 10 drives the connecting plate 11 and the protective cylinder 12 to move downward, and the buffer pad... 15 first contacts the ground. As the sampling cylinder 8 moves downward to take a sample, the supporting inclined plate 9 moves downward and squeezes the compression spring 13, so that the compression spring 13 is in a compressed state. Under the reaction force of the compression spring 13, the buffer pad 15 is tightly attached to the ground. The sampling cylinder 8 is always located inside the protective cylinder 12, thereby protecting the sampling cylinder 8 and preventing the flying of gravel generated during the sampling process. At the same time, the dust suction fan 17 is started, and the dust generated inside the protective cylinder 12 is absorbed through the dust suction hose 16 and pipe, and the dust is transported to the inside of the filter box 18. The dust is filtered through the filter screen 19 to prevent the dust from flying.

[0022] As an optional technical solution of this utility model, a water injection hose 20 is fixedly connected to the outer surface of the protective cylinder 12. Water can be added to the inside of the protective cylinder 12 through the water injection hose 20, thereby facilitating the cooling of the sampling cylinder 8.

[0023] As an optional technical solution of this utility model, the support rod 2 passes through the T-shaped movable seat 6, and the T-shaped movable seat 6 is slidably connected to the support rod 2. The support rod 2 guides the T-shaped movable seat 6, so that the T-shaped movable seat 6 can only move in a straight line along the direction of the support rod 2.

[0024] As an optional technical solution of this utility model, the center of the sampling cylinder 8 and the center of the protective cylinder 12 are on the same vertical plane. The outer diameter of the sampling cylinder 8 is smaller than the inner diameter of the protective cylinder 12, and the outer diameter of the sampling cylinder 8 is smaller than the diameter of the perforation 14. This avoids interference between the sampling cylinder 8 and the protective cylinder 12 during rotation, and allows the sampling cylinder 8 to rotate smoothly.

[0025] As an optional technical solution of this utility model, the bottom end of the lead screw 5 is rotatably connected to the bottom support frame 1 through a bearing, which supports and fixes the bottom end of the lead screw 5, thereby ensuring the stability of the lead screw 5 when rotating.

[0026] As an optional technical solution of this utility model, the cross-sectional shape of the guide rod 10 is T-shaped, and a part of the guide rod 10 is located inside the compression spring 13. The end of the compression spring 13 away from the connecting plate 11 is fixedly connected to the support inclined plate 9, so that the compression spring 13 can generate elastic deformation with the movement of the connecting plate 11, and the guide rod 10 can prevent the compression spring 13 from bending during the elastic deformation process.

[0027] A safety protection device for geological drilling operates on the following principle:

[0028] During the sampling process, the first motor 4 and the second motor 7 are started. With the start of the second motor 7, the sampling cylinder 8 will rotate. With the start of the first motor 4, the lead screw 5 will rotate, thereby causing the T-shaped moving seat 6 to move the sampling cylinder 8 and the supporting inclined plate 9 downward. As the supporting inclined plate 9 moves, the guide rod 10 drives the connecting plate 11 and the protective cylinder 12 to move downward, and the buffer pad 15 first contacts the ground. While the sampling cylinder 8 moves downward to take samples, the supporting inclined plate 9 moves downward and squeezes the compression spring 13, so that the compression spring 13 is in a compressed state. Under the reaction force of the compression spring 13, the buffer pad 15 is tightly attached to the ground. The sampling cylinder 8 is always located inside the protective cylinder 12, thereby protecting the sampling cylinder 8 and avoiding the flying of gravel generated during the sampling process. At the same time, the dust suction fan 17 is started, and the dust generated inside the protective cylinder 12 is absorbed through the dust suction hose 16 and the pipe, and the dust is transported to the inside of the filter box 18, where the dust is filtered through the filter screen 19.

[0029] In summary, this safety protection device for geological drilling, through the coordinated arrangement of a first motor 4, lead screw 5, T-shaped moving seat 6, second motor 7, sampling cylinder 8, supporting inclined plate 9, guide rod 10, connecting plate 11, protective cylinder 12, compression spring 13, perforation 14, and buffer pad 15, adds a protective structure to the outside of the sampling cylinder 8. This protects the sampling cylinder 8 during sampling, preventing the splashing of gravel and thus avoiding injury to the operators. Therefore, the device has good safety performance. Furthermore, through the coordinated arrangement of a suction hose 16, suction fan 17, filter box 18, and filter screen 19, it absorbs and filters dust generated during sampling, preventing dust splashing and environmental pollution, and also preventing operators from inhaling dust, further ensuring the health of the operators.
