Technical Field

[0001] This invention relates to the field of geological exploration rod technology, specifically a rod for geological exploration. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. Before geological exploration, it is often necessary to locate the exploration site. Usually, this is done by drilling a hole with a drilling machine and then inserting a positioning rod into the hole for easy location later.

[0015] This invention provides a rod for geological exploration. Compared with the prior art, it has the following advantages: 1. In this invention, the rod body is driven into the soil by the conical head on the rod body. At the same time, the electric push rod is activated to drive the lifting block to slide in the installation groove. The stabilizing slide rod on the lifting block will be limited by the stabilizing slide groove 15, thereby driving the installation block to move vertically downward. The upper connecting frame on the installation block will synchronously drive the connecting pressure rod to move. Through the cooperation of the connecting pressure rod and the stabilizing pressure rod, the stabilizing pressure rod is driven by the cooperation of the drive shaft and the lower connecting frame, which facilitates the rotation of the tilted stabilizing pressure rod to a horizontal state. Through the cooperation of the connecting pressure rod and the stabilizing pressure rod, the stability of the rod body in the soil is ensured by the triangular support principle. 2. In this invention, when the stabilizing bar rotates around the drive shaft, it will synchronously drive the large sprocket to rotate. When the large sprocket rotates, it will drive the small sprocket to rotate through the chain. When the small sprocket rotates, it will drive the gripper teeth to rotate through the connecting rod. When the stabilizing bar rotates to a horizontal state, the gripper teeth on the stabilizing bar will be in an inclined state, and at the same time, the gripper teeth will be stuck into the soil, thereby improving the stability of the stabilizing bar for the bar body. 3. In this invention, when the lifting block descends, it will synchronously drive the auxiliary pressure rod to descend. The L-shaped vertical plate on the auxiliary pressure rod will synchronously drive the tooth block assembly to descend. During the descent, the tooth block assembly will mesh with the auxiliary gear, thereby causing the auxiliary gear to rotate around the upper rotating shaft. The central fixing rod on the auxiliary gear will extend from the upper vertical groove. Through the contact between the central fixing rod and the soil, the use effect of the rod body will be improved.

[0016] 4. In this invention, when the auxiliary pressure rod descends to an appropriate height, it will contact the top of the auxiliary vertical rod. Simultaneously, the continuous downward pressure of the auxiliary pressure rod will drive it to descend. Then, by utilizing the cooperation between the lower pressure rod and the circular plate, the lower pressure frame will be driven to descend. During the descent of the lower pressure frame, the push frame rod will move synchronously. By utilizing the cooperation between the push frame and the lower fixed rod, and the cooperation between the horizontal slider and the horizontal slide groove, the lower fixed rod in the lower vertical groove will move horizontally outward. By utilizing the contact between the lower fixed rod and the soil, the stability of the rod body is further improved. Attached Figure Description

The installation effect of the rod is improved by the spiral part. Since the working principle of the warning light 5 and the spiral part is a technology well known to those skilled in the art, it will not be described in detail here.

[0021] In this embodiment, the rod 1 is driven into the soil by the conical head 2 on the rod body 1. At the same time, the electric push rod 7 is activated to drive the lifting block 8 to slide in the mounting groove 6. The stabilizing slide rod 11 on the lifting block 8 will be limited by the stabilizing slide groove 15, thereby driving the mounting block 16 to move vertically downward. The upper connecting frame 13 on the mounting block will synchronously drive the connecting pressure rod 14 to move. Through the cooperation of the connecting pressure rod 14 and the stabilizing pressure rod 19, the stabilizing pressure rod 19 is driven by the rotating shaft 18 and the lower connecting frame 17 to rotate the tilted stabilizing pressure rod 19 to a horizontal state.

[0023] In this embodiment, when the stabilizing bar 19 rotates around the drive shaft 18, it will synchronously drive the large sprocket 20 to rotate. When the large sprocket 20 rotates, it will drive the small sprocket 22 to rotate through the chain. When the small sprocket 22 rotates, it will drive the gripper tooth 23 to rotate through the connecting rod 21. When the stabilizing bar 19 rotates to a horizontal state, the gripper tooth 23 on the stabilizing bar 19 will be in an angled state. At the same time, the gripper tooth 23 will be stuck into the soil, thereby improving the stability of the stabilizing bar 19 on the bar body 1.

[0024] An auxiliary component is installed inside the mounting slot 6. The auxiliary component includes a middle fixed rod 9 and a lower fixed rod 10. The auxiliary component includes an auxiliary pressure rod 24 fixedly installed on the lifting block 8. The side end face of the auxiliary pressure rod 24 is fixedly installed on multiple L-shaped vertical plates 25. The outer side of the L-shaped vertical plate 25 is provided with a toothed block assembly 26. The outer side of the rod body 1 is provided with an upper vertical groove 27. An upper rotating shaft 28 is rotatably installed on the side end face of the upper vertical groove 27. An auxiliary gear 29 is fixedly installed on the outer side of the upper rotating shaft 28. The middle fixed rod 9 is fixedly installed on the lower end face of the auxiliary gear 29. The toothed block assembly 26 meshes with the auxiliary gear 29. The position of the middle fixed rod 9 is inside the upper vertical groove 27. The number of L-shaped vertical plates 25 is the same as the number of upper vertical grooves 27. By using the outward expansion of multiple middle fixed rods, the contact area between the vertical rod and the soil is increased, enhancing the stability of the rod body 1.

[0025] In this embodiment, when the lifting block 8 descends, it will synchronously drive the auxiliary pressure rod 24 to descend. The L-shaped vertical plate 25 on the auxiliary pressure rod 24 will synchronously drive the tooth block assembly 26 to descend. During the descent, the tooth block assembly 26 will mesh with the auxiliary gear 29, causing the auxiliary gear 29 to rotate around the upper rotating shaft 28. The central fixing rod 9 on the auxiliary gear 29 will extend from the upper vertical groove 27. Through the contact between the central fixing rod 9 and the soil, the use effect of the rod body 1 will be improved.

[0026] A T-shaped vertical rod 30 is fixedly installed at the bottom of the mounting slot 6. A lower pressure frame 31 is slidably installed on the T-shaped vertical rod 30. A return spring 32 is fixedly connected to the lower pressure frame 31. A lower pressure rod 33 is fixedly installed on the upper end face of the lower pressure frame 31. A circular plate 34 is fixedly installed at the top of the lower pressure rod 33. An auxiliary vertical rod 35 is fixedly installed on the upper end face of the circular plate 34. A push frame rod 36 is rotatably installed inside the lower pressure frame 31. A horizontal slider 37 is fixedly installed on the side end face of the lower fixed rod 10. A lower vertical groove 38 is opened on the side end face of the rod body 1. A horizontal sliding groove 39 is opened inside the lower vertical groove 38. The lower fixed rod 10 is rotatably installed... Mounted on the push rod 36, the horizontal slider 37 is slidably installed with the horizontal slide groove 39. The end of the return spring 32 away from the lower pressure frame 31 is fixedly connected to the inner bottom of the mounting groove 6. The position of the return spring 32 is on the outside of the T-shaped vertical rod 30. The auxiliary vertical rod 35 and the auxiliary pressure rod 24 are in the same vertical direction. When the auxiliary pressure rod 24 descends to an appropriate height, it will contact the top of the auxiliary vertical rod 35. At the same time, the continuous downward pressure of the auxiliary pressure rod 24 will drive the auxiliary pressure rod 24 to descend. When the auxiliary pressure rod 24 rises, the auxiliary vertical rod 35 will return to its original position through the reaction force of the auxiliary spring.

[0027] In this embodiment, when the auxiliary pressure rod 24 descends to an appropriate height, it will contact the top of the auxiliary vertical rod 35. At the same time, the continuous downward pressure of the auxiliary pressure rod 24 will drive the auxiliary pressure rod 24 to descend. Then, by utilizing the cooperation between the lower pressure rod 33 and the circular plate 34, the lower pressure frame 31 will be driven to descend. During the descent, the lower pressure frame 31 will drive the push frame rod 36 to move synchronously. By utilizing the cooperation between the push frame and the lower fixed rod 10, and the cooperation between the horizontal slider 37 and the horizontal slide groove 39, the lower fixed rod 10 in the lower vertical groove 38 will move horizontally outward. By utilizing the contact between the lower fixed rod 10 and the soil, the stability of the rod body 1 will be further improved.

[0028] Working principle: The conical head 2 on the rod 1 drives the rod 1 into the soil. At the same time, the electric push rod 7 is activated, which drives the lifting block 8 to slide in the mounting groove 6. The stabilizing slide rod 11 on the lifting block 8 will be limited by the stabilizing slide groove 15, thereby driving the mounting block 16 to move vertically downward. The upper connecting frame 13 on the mounting block will synchronously drive the connecting pressure rod 14 to move. Through the cooperation of the connecting pressure rod 14 and the stabilizing pressure rod 19, the stabilizing pressure rod 19 is driven by the shaft 18 and the lower connecting frame 17 to rotate the tilted stabilizing pressure rod 19 to a horizontal position. In this configuration, the connection between the pressure rod 14 and the stabilizing pressure rod 19 utilizes the triangular support principle to ensure the stability of the rod 1 in the soil. When the stabilizing pressure rod 19 rotates around the drive shaft 18, it synchronously drives the large sprocket 20 to rotate. The large sprocket 20, in turn, drives the small sprocket 22 via a chain. The small sprocket 22, in turn, drives the gripper tooth 23 via the connecting rod 21. When the stabilizing pressure rod 19 rotates to a horizontal position, the gripper tooth 23 on the stabilizing pressure rod 19 will be in an inclined state, and simultaneously, the gripper tooth 23 will engage in the soil, thereby achieving stability. To improve the stability of the rod body 1, the lifting block 8 synchronously drives the auxiliary pressure rod 24 to descend during its descent. The L-shaped vertical plate 25 on the auxiliary pressure rod 24 synchronously drives the toothed block assembly 26 to descend. During descent, the toothed block assembly 26 meshes with the auxiliary gear 29, causing the auxiliary gear 29 to rotate around the upper shaft 28. The centering rod 9 on the auxiliary gear 29 extends from the upper vertical groove 27. Through the contact between the centering rod 9 and the soil, the performance of the rod body 1 is improved. When the auxiliary pressure rod 24 descends to an appropriate... When the height is reached, it will contact the top of the auxiliary vertical rod 35. At the same time, the continuous downward pressure of the auxiliary pressure rod 24 will drive the auxiliary pressure rod 24 to descend. Then, by utilizing the cooperation between the lower pressure rod 33 and the circular plate 34, the lower pressure frame 31 will be driven to descend. During the descent, the lower pressure frame 31 will drive the push frame rod 36 to move synchronously. By utilizing the cooperation between the push frame and the lower fixed rod 10, and the cooperation between the horizontal slider 37 and the horizontal slide groove 39, the lower fixed rod 10 in the lower vertical groove 38 will move horizontally outward. By utilizing the contact between the lower fixed rod 10 and the soil, the stability of the rod body 1 will be further improved.
