Description

Technical Field

[0001] This utility model relates to the field of rock and soil exploration technology, and in particular to an auxiliary device for rock and soil exploration. Background Technology

[0002] Geotechnical exploration refers to the activity of investigating and studying the geological, environmental characteristics and geotechnical engineering conditions of a construction site by using various surveying techniques and methods, according to the requirements of the construction project.

[0003] Chinese patent announcement number CN222066676U discloses a drill bit extraction device. This device includes a worktable, two pushing components, a drive motor, and a moving component. The worktable has legs at its bottom and a through hole for the drill bit sampling tube to pass through. Both pushing components are mounted on the worktable and each has a rotatable extraction wheel. The two pushing components can drive the extraction wheels to approach the drill bit sampling tube along a direction parallel to a first straight line, so that the two extraction wheels abut against the drill bit sampling tube from opposite sides. The drive motor is connected to either of the extraction wheels and drives the extraction wheel to rotate. The moving component includes an adjusting screw and traveling wheels. The adjusting screw drives the traveling wheels to move vertically, so that the traveling wheels support the worktable. This drill bit extraction device extracts the drill bit sampling tube from the soil layer by rotating the extraction wheels, which is convenient, quick, and saves time and effort.

[0004] However, this device has the following drawbacks in use: Although it can pull out the sampling rod, during exploration, multiple sampling rods are assembled together to form a long rod (mostly threaded connections) according to the sampling depth. Therefore, after pulling out the sampling rod, it is still necessary to use a wrench to laboriously disassemble the multiple threaded sampling rods, making it difficult to disassemble the sampling rod quickly and effortlessly. To address these drawbacks, we propose an auxiliary device for geotechnical exploration. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for geotechnical investigation.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a geotechnical investigation auxiliary device, comprising:

[0007] A sampling rod, comprising a rod body and two sets of mounting slots symmetrically formed on the surface of the rod body;

[0008] The sampling rod pull-out structure includes a base, two first hydraulic cylinders symmetrically fixedly installed on the upper surface of the base, and a sampling rod clamping assembly set at the upper end of the two first hydraulic cylinders. The upper end of the base is provided with a through hole for the sampling rod to pass through.

[0009] The sampling rod disassembly structure consists of a limit wrench, a positioning wrench, and a drive assembly disposed on the upper surface of the base for driving the positioning wrench to rotate.

[0010] The drive assembly includes four support rods fixedly mounted in a circumferential array on the upper end of the base, a support ring fixedly mounted on the upper end of the support rods, a rotating disk rotatably mounted on the inner wall of the support ring, a stop block fixedly mounted on the lower end of the rotating disk, and a power source component set on the upper end of the base for driving the rotating disk to rotate.

[0011] Preferably, the power source component includes a hydraulic rotary motor fixedly mounted on the upper end of the base, a spur gear fixedly mounted on the output end of the hydraulic rotary motor, and a gear ring fixedly mounted on the upper end of the rotating disk.

[0012] Preferably, the spur gear meshes with a gear ring for transmission.

[0013] Preferably, both the limiting wrench and the positioning wrench can be engaged in the assembly slot.

[0014] Preferably, the sampling rod clamping assembly includes a connecting seat fixedly installed on the upper end of two first hydraulic cylinders, a through groove opened on the upper end of the connecting seat, two semi-circular clamping plates slidably connected to the inner wall of the through groove, and a second hydraulic cylinder fixedly installed on the front and back of the connecting seat to drive the two semi-circular clamping plates to move.

[0015] Preferably, the inner diameter of the two semicircular clamps is adapted to the outer diameter of the rod, and the inner wall of the semicircular clamps is provided with anti-slip grooves.

[0016] Preferably, a contact block is fixedly mounted on the surface of the positioning wrench.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a sampling rod splitting structure, the sampling rod is placed in the through slot, and then the sampling rod clamping assembly can clamp the sampling rod. Then, the first hydraulic cylinder is driven to rise and pull up the sampling rod. When the assembly slots on the opposite sides of the two sampling rods are pulled out of the ground and rise to the height of the support rod, a limit wrench can be used to engage in the assembly slot on the surface of the lower sampling rod, with one end of the limit wrench in contact with the support rod. The positioning wrench is engaged in the assembly slot on the surface of the upper sampling rod. Then, the drive assembly drives the stop block to contact the contact block. Since the limit wrench is limited by the obstruction of the support rod, the rotating stop block can push the contact block to rotate, thereby separating the two threaded rods. This completely solves the problem of traditional disassembly relying on manual wrenches, which is time-consuming and laborious, and significantly improves the disassembly efficiency.

[0019] 2. By setting up a sampling rod extraction structure, the connecting seat is driven to rise by the first hydraulic cylinder, thereby vertically pulling the rod out of the soil layer. After a single stroke is completed, the second hydraulic cylinder releases the clamp, the first hydraulic cylinder resets and descends, clamps again and repeats the lifting action. Through cyclic operation, the entire sampling rod is pulled out of the ground segment by segment. The reciprocating lifting and lowering of the first hydraulic cylinder and the alternating clamping and releasing of the clamping components realize the segmented and efficient extraction of the sampling rod.

Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-8This utility model provides a technical solution: a geotechnical exploration auxiliary device, comprising: a sampling rod, a sampling rod pull-out structure, and a sampling rod disassembly structure.

[0032] Specifically, the sampling rod includes a rod body 10 and two sets of assembly slots 11 symmetrically opened on the surface of the rod body 10. One end of the rod body 10 is provided with a threaded hole, and the other end is fixedly installed with a threaded post. The two rod bodies 10 can be assembled into one unit by using the threaded holes and threaded posts at both ends of the rod body 10.

[0033] Specifically, the sampling rod extraction structure includes a base 20, two first hydraulic cylinders 21 symmetrically fixedly installed on the upper surface of the base 20, and a sampling rod clamping assembly disposed on the upper end of the two first hydraulic cylinders 21. The upper end of the base 20 is provided with a through hole for the sampling rod to pass through. The sampling rod clamping assembly includes a connecting seat 60 fixedly installed on the upper end of the two first hydraulic cylinders 21, a through groove opened on the upper end of the connecting seat 60, two semi-circular clamping plates 61 slidably connected to the inner wall of the through groove, and a second hydraulic cylinder 62 fixedly installed on the front and back of the connecting seat 60 to drive the two semi-circular clamping plates 61 to move. The inner diameter of the two semi-circular clamping plates 61 is adapted to the outer diameter of the rod body 10, and the inner wall of the semi-circular clamping plates 61 is provided with an anti-slip groove to ensure that the sampling rod does not slip during extraction.

[0034] The rod 10 is passed through the through hole and the through slot respectively. Then, the second hydraulic cylinder 62 is activated to push the two semi-circular clamps 61 to move towards the center along the through slot in the connecting seat 60. The rod 10 can be clamped by the two semi-circular clamps 61. Then, the first hydraulic cylinder 21 is driven to rise, so that the rod 10 can be pulled out of the ground. Then, the sampling rod clamping assembly releases the rod 10, the first hydraulic cylinder 21 descends to the reset position, and then the sampling rod clamping assembly clamps the rod 10 again. Then, the first hydraulic cylinder 21 is driven to rise again to pull the rod 10 upward again. The cycle is repeated to pull out the rod 10 as a whole, realizing the segmented and efficient extraction of the sampling rod.

[0035] The sampling rod splitting structure consists of a limit wrench 30, a positioning wrench 31, and a drive assembly set on the upper surface of the base 20 for driving the positioning wrench 31 to rotate. Both the limit wrench 30 and the positioning wrench 31 can be inserted into the assembly slot 11, and a contact block 32 is fixedly installed on the surface of the positioning wrench 31.

[0036] The drive assembly includes four support rods 40 fixedly mounted in a circular array on the upper end of the base 20, a support ring 43 fixedly mounted on the upper end of the support rods 40, a rotating disk 41 rotatably mounted on the inner wall of the support ring 43, a stop block 42 fixedly mounted on the lower end of the rotating disk 41, and a power source component set on the upper end of the base 20 to drive the rotating disk 41 to rotate. The power source component includes a hydraulic rotary motor 50 fixedly mounted on the upper end of the base 20, a spur gear 51 fixedly mounted on the output end of the hydraulic rotary motor 50, and a gear ring 52 fixedly mounted on the upper end of the rotating disk 41. The spur gear 51 meshes with the gear ring 52 for transmission. Driving the hydraulic rotary motor 50 can drive the spur gear 51 to rotate. By using the meshing transmission between the spur gear 51 and the gear ring 52, the rotating disk 41 can be driven to rotate. At this time, the stop block 42 will rotate synchronously. The first hydraulic cylinder 21, the hydraulic rotary motor 50, and the second hydraulic cylinder 62 are all connected to an external hydraulic control system.

[0037] After the mounting slots 11 on the opposite sides of the two sampling rods are pulled out of the ground and rise to the height of the support rod 40, the limiting wrench 30 can be used to engage in the mounting slot 11 on the surface of the lower sampling rod, with one end of the limiting wrench 30 in contact with the support rod 40. The positioning wrench 31 is engaged in the mounting slot 11 on the surface of the upper sampling rod. Then, the drive assembly drives the stop block 42 to contact the contact block 32. Since the limiting wrench 30 can be limited by the support rod 40 to prevent it from rotating, the stop block 42 will contact the contact block 32 after rotating, thereby pushing the contact block 32 to rotate and generating torque to separate the two threaded rods 10. This completely solves the problem of traditional disassembly relying on manual wrenches, which is time-consuming and laborious, and significantly improves the disassembly efficiency.

[0038] Specifically, the working principle and operation method of this utility model are as follows:

[0039] Clamping and fixing: Pass the rod 10 through the through hole of the base 20 and the through groove of the connecting seat 60, start the second hydraulic cylinder 62, push the two semi-circular clamping plates 61 to slide towards the center, and use the anti-slip groove to clamp the rod 10 to prevent slippage.

[0040] Hydraulic segmental lifting: The first hydraulic cylinder 21 drives the connecting seat 60 to rise, vertically pulling the rod 10 out of the rock and soil layer. After a single stroke is completed, the second hydraulic cylinder 62 releases the clamp, the first hydraulic cylinder 21 resets and descends, clamps again and repeats the lifting action. Through cyclic operation, the entire sampling rod is pulled out of the ground segment by segment.

[0041] Wrench locking: When the threaded connection of two adjacent rod sections 10 is exposed to the height of the support rod 40, the limiting wrench 30 is locked into the assembly groove 11 of the lower rod section 10, and its end abuts against the support rod 40 to form a fixed fulcrum; at the same time, the positioning wrench 31 is locked into the assembly groove 11 of the upper rod section 10, and its contact block 32 and the stop block 42 form a power transmission interface.

[0042] Gear-driven rotation: Start the hydraulic rotary motor 50, the spur gear 51 drives the gear ring 52 to mesh and drive the rotating disk 41 and the stop block 42 to rotate around the axis of the rod body 10. The stop block 42 pushes the contact block 32, forcing the positioning wrench 31 to drive the upper rod body 10 to rotate. The limit wrench 30 cannot rotate due to the obstruction of the support rod 40, forming a reverse torque, causing the threaded holes of the two rod bodies 10 to loosen and separate from the external threads in the opposite direction.

[0043] Equipment reset cycle: After disassembly, the hydraulic rotary motor 50 reverses and the rotary disk 41 resets; the semi-circular clamp 61 is released, the disassembled rod 10 moves out of the work position, the device returns to its initial state, and it is ready for the next operation.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
