[0044] Reference Figures 1-8 The utility model discloses an embodiment shows a kind of two-way probe rod loading mechanism, including center seat 1 and two clamping mechanisms 2, two clamping mechanisms 2 are symmetrically arranged in the upper and lower ends of the center seat 1, the passage (not marked in drawing) for probe rod T vertical through is formed between the center seat 1 with the clamping mechanism 2;

[0045] The clamping mechanism 2 includes base 21, guide seat 22, several wedge-shaped clamping blocks 23 and elastic component 24;The base 21 is arranged on the center seat 1;The guide seat 22 is arranged in the end of the base 21 away from the center seat 1 in a lifting manner, to realize the distance between the guide seat 22 and the center seat 1 is adjusted;Several first guide inclined surfaces 221 are equipped on the guide seat 22, and the first guide inclined surface 221 and the horizontal plane of the position where the center seat 1 is located form an acute angle;Second guide inclined surface 231 is equipped on the wedge-shaped clamping block 23 and is slidably connected with the first guide inclined surface 221;The elastic component 24 is arranged between the center seat 1 and base 21, and the elastic component 24 is used to exert elastic force away from the center seat 1 to the wedge-shaped clamping block 23.

[0046] The working principle of the upper clamping mechanism 2 is described as follows:

[0047] As Figure 5 And Figure 6 As shown in the drawings, the distance between the guide seat 22 and the center seat 1 can be adjusted by adjusting the position of the guide seat 22 on the base 21, and the distance between the guide seat 22 and the center seat 1 will affect the elastic force exerted by the elastic component 24 on the wedge-shaped clamping block 23;The closer the guide seat 22 is to the center seat 1, the closer the distance between the wedge-shaped clamping block 23 and the center seat 1, and the greater the elastic force exerted by the elastic component 24 on the wedge-shaped clamping block 23;

[0048] In the initial state, the guide seat 22 is adjusted to a suitable position. At this time, the elastic component 24 provides a certain elastic force to the wedge-shaped clamping block 23. Under the guiding action of the first guide inclined surface 221 of the guide seat 22 and the elastic force of the elastic component 24, the wedge-shaped clamping block 23 approaches the probe rod T and forms a certain clamping force between the probe rod T and the probe rod T. This clamping force is defined as the initial clamping force. The initial clamping force should be less than the friction force between the probe rod T and the geological soil.

[0049] During the downward insertion of the probe T, the center seat 1 is pushed downwards. The center seat 1, base 21, and guide seat 22 are relatively fixed and therefore descend together. As the guide seat 22 moves downwards, the first guide ramp 221 causes the wedge-shaped clamp 23 to tend towards the probe T, increasing the clamping force of the wedge-shaped clamp 23 on the probe T, thereby driving the probe T downwards and achieving insertion. Due to ground obstruction, after descending a certain depth, the bidirectional probe loading mechanism needs to be moved upwards again. At this time, the center seat 1 is pushed upwards. Moving the guide seat 22 upward causes the first guide slope 221 to cause the wedge-shaped clamping block 23 to tend to move away from the probe rod T, reducing the clamping force of the wedge-shaped clamping block 23 on the probe rod T to the initial clamping force. Since the initial clamping force is less than the friction between the probe rod T and the geological soil, the wedge-shaped clamping block 23 will not drive the probe rod T to rise, but will slip between the wedge-shaped clamping block 23 and the probe rod T. After the bidirectional probe loading mechanism has completed its upward movement, the center seat 1 can be pushed downward again. This process is repeated multiple times to allow the probe rod T to penetrate to a certain depth in the geological geology.

[0050] Conversely, the clamping mechanism 2 located below is symmetrically arranged with the clamping mechanism 2 located above. The two clamping mechanisms 2 work on the same principle, but the difference is that the clamping mechanism 2 located below clamps the probe rod T when it rises and releases the probe rod T when it falls. In other words, the clamping mechanism 2 located above is used to clamp the probe rod T when it is inserted, while the clamping mechanism 2 located below is used to clamp the probe rod T when it is pulled out.

[0051] In order to avoid the clamping mechanism 2 located below affecting the penetration of the probe T, and also to avoid the clamping mechanism 2 located above affecting the pulling out of the probe T;

[0052] When pulling out the probe T, the guide seat 22 in the clamping mechanism 2 located above should be adjusted, such as... Figure 6 As shown, the guide seat 22 is moved away from the center seat 1, so that the upper elastic component 24 does not provide elastic force to the wedge-shaped clamp 23 or only provides a very small elastic force. In this way, when the center seat 1 is pushed down, the lower clamping mechanism 2 will release the probe T. At the same time, the wedge-shaped clamp 23 in the upper clamping mechanism 2 cannot reliably clamp the probe T due to the lack of elastic force provided by the elastic component 24, and therefore will not drive the probe T down.

[0053] Similarly, when the probe rod T is being penetrated, the guide seat 22 in the lower clamping mechanism 2 should be adjusted to be away from the center seat 1, so that the elastic assembly 24 in the lower clamping mechanism 2 does not provide elastic force or only provides a small elastic force to the wedge-shaped clamping block 23, so that when the center seat 1 is pushed upward, the upper clamping mechanism 2 releases the probe rod T, and the wedge-shaped clamping block 23 in the lower clamping mechanism 2 cannot reliably clamp the probe rod T due to the lack of elastic force provided by the elastic assembly 24, so the probe rod T will not be lifted.

[0054] In the above scheme, the center seat 1 can be pushed upward or downward manually by using a conventional lever device, or the center seat 1 can be pushed upward or downward by a power source such as a hydraulic pump or an engine.

[0055] In some embodiments, in order to facilitate the upward and downward pushing of the center seat 1 by manually using a conventional lever device, as shown in Figure 1 , a plurality of loading rods 11 are arranged on the outer side of the center seat 1, so that the lever device can be used to exert force on the loading rods 11 to move the center seat 1 upward or downward.

[0056] In some embodiments, in order to facilitate the adjustment of the position of the guide seat 22 on the base 21, as shown in Figures 3-6 , a first connecting part 211 in the shape of a cylinder is arranged on the base 21, and an internal thread structure is formed in the inside of the first connecting part 211; the base 21 and the center seat 1 form a connection structure that is axially relatively fixed and circumferentially relatively rotatable; a second connecting part 222 in the shape of a cylinder is arranged on the guide seat 22, and an external thread structure is formed on the outside of the second connecting part 222, and the second connecting part 222 is threadedly connected with the first connecting part 211; the clamping mechanism 2 further comprises a guide rod 25, which is relatively fixed with the center seat 1 and is vertically arranged and slidably connected with the guide seat 22.

[0057] Specifically, under the limitation of the guide rod 25, the guide seat 22 can only be lifted and lowered along the guide rod 25; when it is necessary to adjust the position of the guide seat 22, the base 21 can be rotated, and the base 21 only rotates circumferentially without moving axially; when the base 21 rotates, the guide seat 22 is lifted and lowered, thereby adjusting the position of the guide seat 22.

[0058] Further, in order to facilitate the formation of the connection structure between the base 21 and the center seat 1 that is axially relatively fixed and circumferentially relatively rotatable, as shown in Figure 3 and Figure 5As shown, the clamping mechanism 2 further comprises a connecting base 26 fixedly arranged at the end of the center base 1, and the outer side of the connecting base 26 is provided with a first limiting protrusion 261; the inner wall of the base 21 near one end of the center base 1 is provided with a second limiting protrusion 212, which is arranged between the first limiting protrusion 261 and the center base 1, and blocks the first limiting protrusion 261 from moving in the axial direction, so as to realize the relative fixing in the axial direction and the relative rotation in the circumferential direction between the base 21 and the center base 1.

[0059] According to the working principle, when the switch rod T is in the penetrating mode and the pulling mode, the positions of the guide seats 22 above and below need to be adjusted. Specifically, when the penetrating mode is needed, the guide seat 22 above should be adjusted to be closer to the center base 1, so that the elastic assembly 24 above can provide a certain elastic force, and the guide seat 22 below should be adjusted to be farther away from the center base 1, so that the elastic assembly 24 below does not provide an elastic force or only provides a very small elastic force; when the pulling mode is needed, the opposite is true.

[0060] In some embodiments, in order to quickly position the guide seat 22 close to the center base 1, the first limiting protrusion 261 of the connecting base 26 is provided with a first limiting groove 2611, and the second limiting protrusion 212 of the base 21 is provided with a second limiting groove 2121, which are matched with each other. Figures 4-6 As shown, the clamping mechanism 2 further comprises a positioning seat 28, which is threadedly connected to the outer side of the first connecting part 211 on the base 21, so as to realize the lifting arrangement of the positioning seat 28 on the base 21; and the outer part of the guide seat 22 is provided with a blocking part 223 for being blocked by the positioning seat 28.

[0061] In this way, when the guide seat 22 is adjusted in the lifting direction, when the blocking part 223 of the guide seat 22 is blocked by the positioning seat 28, it means that the position of the guide seat 22 is adjusted to the right position; in addition, the positioning seat 28 can adjust its position on the base 21, so that the position of the positioning seat 28 can be adjusted according to the required initial clamping force, and then the corresponding position positioning effect of the guide seat 22 is provided.

[0062] Further, in order to avoid the axial movement between the positioning seat 28 and the base 21 due to external factors, as shown, Figure 5 the positioning seat 28 is provided with a positioning hole 281 penetrating in the radial direction, and a tight screw (not shown) is threadedly connected in the positioning hole 281. In this way, by tightening the tight screw, the end of the tight screw abuts against the outer part of the base 21, so as to realize the relative fixing between the positioning seat 28 and the base 21; when the position of the positioning seat 28 needs to be adjusted, the tight screw is loosened first, and then the positioning seat 28 is rotated.

[0063] In some embodiments, in order to improve the lifting stability of the probe rod T, as shown in Figure 3 The clamping mechanism 2 further comprises a guide cylinder 27 arranged at the center of the base 21 and the guide seat 22. The guide cylinder 27 is fixed opposite to the guide seat 22. The two sides of the guide cylinder 27 are provided with vertically arranged strip-shaped holes 271 for the wedge-shaped clamping block 23 to pass through. The material of the guide cylinder 27 has self-lubricating properties, which can provide a guide function for the probe rod T, thereby improving the lifting stability of the probe rod T. At the same time, the strip-shaped holes 271 do not affect the clamping of the probe rod T by the wedge-shaped clamping block 23.

[0064] According to the working principle described above, when the probe rod T is being driven into the ground, the lower guide seat 22 is adjusted to be away from the center seat 1, so that the lower elastic assembly 24 does not provide elastic force or only provides very small elastic force, thereby avoiding the lower wedge-shaped clamping block 23 from lifting the probe rod T when the center seat 1 is lifted. However, due to the action of gravity, the lower wedge-shaped clamping block 23 will still exert a certain clamping force on the probe rod T, although it will not lift the probe rod T, but it will make the bidirectional probe rod loading mechanism more difficult to move upward.

[0065] Therefore, in some embodiments, as shown in Figure 3 , Figure 7 and Figure 8 The bidirectional probe rod loading mechanism further comprises a limiting snap ring 3 arranged on the lower clamping mechanism 2. The limiting snap ring 3 comprises a ring body 31 for the probe rod T to pass through. One end of the ring body 31 is provided with a plurality of hanging ears 32. The inner wall of the hanging ear 32 is provided with a clamping block 33. The clamping block 33 is buckled connected with the lower edge of the strip-shaped hole 271 of the guide cylinder 27. The end of the hanging ear 32 abuts against the lower wedge-shaped clamping block 23, so that the lower wedge-shaped clamping block 23 is kept a certain distance from the center of the channel.

[0066] In this way, by arranging the limiting snap ring 3, the lower wedge-shaped clamping block 23 is separated from the probe rod T, or only a small clamping force is maintained, thereby reducing the load of the bidirectional probe rod loading mechanism when moving upward. When the probe rod T is driven into the ground, the limiting snap ring 3 is installed. When the probe rod T is pulled out, the limiting snap ring 3 is pulled away from the guide cylinder 27, so that the lower wedge-shaped clamping block 23 can work normally.

[0067] In some embodiments, in order to avoid the wedge-shaped sliding block from falling into the channel when the probe rod T is not arranged in the channel, as shown in Figure 4As shown, the wedge-shaped clamping block 23 is provided with a guide block 232 on both sides; the guide seat 22 is provided with a guide groove 224 for the sliding of the guide block 232, and the inclination of the guide groove 224 is the same as that of the first guide inclined surface 221. In this way, the limitation of the guide groove 224 to the guide block 232 can make the wedge-shaped clamping block 23 only move along the first guide inclined surface 221.

[0068] In some embodiments, as shown in Figure 5 As shown, the elastic assembly 24 includes a first pressing plate 241, a second pressing plate 242, and a spring 243 arranged between the first pressing plate 241 and the second pressing plate 242. In this embodiment, the wedge-shaped clamping block 23 in the clamping mechanism 2 is provided with two, and the first pressing plate 241 can simultaneously apply a push to the two wedge-shaped clamping blocks 23.

[0069] In summary, the application provides a bidirectional probe rod loading mechanism, which can realize stable clamping of the probe rod T during the penetration and pulling of the probe rod T, has a small volume and is convenient to carry; it can not only work with power sources such as hydraulic pumps and engines, but also can work with manual operation, thereby reducing the dependence on professional equipment and power supply, and even in the case of insufficient equipment conditions, it can be flexibly coped with, thereby expanding the application range.

[0070] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0071] The above only describes the preferred embodiments of the application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and replacements can be made without departing from the technical principles of the application, and these improvements and replacements should also be regarded as the protection scope of the application.
