[0048] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0052] refer to Figures 1-8 An embodiment of this utility model shows a unidirectional friction wheel type probe loading device, including a frame 1, two sets of clamping mechanisms and a limiting guide mechanism 5;

[0053] Two sets of clamping mechanisms are symmetrically arranged on the frame 1, and each set of clamping mechanism comprises an operating rod 2, a movable assembly 3 and a one-way clamping wheel assembly 4; the first end of the operating rod 2 is hingedly connected to the frame 1, and the second end of the operating rod 2 is an operating end 21; the movable assembly 3 is arranged on the frame 1 in a liftable manner, and is used for connecting the operating rod 2 and the one-way clamping wheel assembly 4, and the movable assembly 3 is driven to lift by the operating rod 2; the one-way clamping wheel assembly 4 comprises a main shaft 41, a roller 43 rotatably arranged on the main shaft 41 and a one-way bearing 42 arranged between the main shaft 41 and the roller 43, and the main shaft 41 is connected to the movable assembly 3 and is driven to lift by the movable assembly 3;

[0054] Two rollers 43 of the two sets of clamping mechanisms are clamped on both sides of the probe rod T, and the rollers 43 are realized one-way rotation on the main shaft 41 through the one-way bearing 42, one roller 43 can only rotate clockwise, and the other roller 43 can only rotate counterclockwise;

[0055] The limiting guide mechanism 5 comprises a limiting connecting rod 51 arranged horizontally and a limiting stopper 52 detachably arranged on the limiting connecting rod 51; the limiting connecting rod 51 is slidably arranged on the main shaft 41 of the two one-way clamping wheel assemblies 4, and the limiting stopper 52 is used for blocking the two main shafts 41 from moving away from each other.

[0056] The specific working principle of the above embodiment is as follows:

[0057] For the convenience of understanding, the two rollers 43 are respectively referred to as a first roller 43 and a second roller 43, the first roller 43 and the second roller 43 are symmetrically arranged, and the rotation directions of the two rollers 43 are opposite and one-way rotation.

[0058] When the probe rod T is operated to penetrate, as shown in Figure 1 and Figure 2 , the first roller 43 can only rotate clockwise, and the second roller 43 can only rotate counterclockwise; during the operation, if the operating rod 2 is lifted upward, the operating rod 2 drives the one-way clamping wheel assembly 4 to rise through the movable assembly 3; and if the operating rod 2 is pressed downward, the operating rod 2 drives the one-way clamping wheel assembly 4 to descend through the movable assembly 3; wherein, as shown in Figure 2As shown, under the obstruction of the limiting block 52 of the limiting guide mechanism 5, the two rollers 43 can be stably clamped on both sides of the probe T. Therefore, when the first roller 43 and the second roller 43 descend, since the first roller 43 cannot rotate counterclockwise and the second roller 43 cannot rotate clockwise, there is sliding friction between the first roller 43 and the probe T. This sliding friction is relatively large and can drive the probe T downward, allowing the probe T to penetrate the formation. Conversely, when the first roller 43 and the second roller 43 rise, the first roller 43 can rotate clockwise and the second roller 43 can rotate counterclockwise. Therefore, there is rolling friction between the first roller 43 and the probe T. This rolling friction is less than the friction between the probe T and the formation. Therefore, the first roller 43 and the second roller 43 will roll upward along the probe T and will not drive the probe T to rise. Therefore, by repeatedly lifting and pressing the operating lever 2 upwards and downwards, the probe T can be inserted into the formation segment by segment.

[0059] When pulling out the probe T: Adjust the first roller 43 and the second roller 43 so that the first roller 43 can only rotate counterclockwise and the second roller 43 can only rotate clockwise. The working principle is basically the same as the penetration operation described above. The difference is that when the first roller 43 and the second roller 43 descend, they will roll down along the probe T and will not drive the probe T to descend. However, when the first roller 43 and the second roller 43 rise, they cannot rotate and will drive the probe T to rise, thereby pulling out the probe T.

[0060] In some embodiments, such as Figure 2 The limiting block 52 is a nut, threadedly connected to the limiting rod 51, and at least one limiting block 52 is provided on the outer side of the main shaft 41. The position of the limiting block 52 on the limiting rod 51 can be adjusted, thereby adjusting the distance between the two rollers 43. It should be noted that the limiting block 52 only prevents the two main shafts 41 from moving away from each other, but does not prevent them from moving closer together. Furthermore, in other embodiments, multiple limiting blocks 52 can be provided to further ensure the distance between the two main shafts 41.

[0061] In this embodiment, the limiting block 52 can be easily removed from the limiting link 51, thereby adjusting the rotation direction of the roller 43 on the one-way clamping wheel assembly 4.

[0062] In some embodiments, to improve the clamping stability of the probe T by the two rollers 43 during penetration and extraction, such as Figure 1 As shown, the active component 3 includes a first link 32, a second link 34, a third link 36, a first slider 31, a second slider 33, and an elastic preload component 35;

[0063] The first slider 31 is slidingly arranged on the operating rod 2; the first end of the first connecting rod 32 is hingedly connected to the first slider 31, and the second end of the first connecting rod 32 is fixedly connected to the second slider 33; the second slider 33 is slidingly arranged on the rack 1 in a vertical direction; the first end of the second connecting rod 34 is hingedly connected to the second slider 33, and the second end of the second connecting rod 34 is connected to the elastic preloading assembly 35; the first end of the third connecting rod 36 is connected to the elastic preloading assembly 35, and the second end of the third connecting rod 36 is hingedly connected to the main shaft 41 of the one-way clamping wheel assembly 4; the third connecting rod 36 is coaxially arranged with the second connecting rod 34; the elastic preloading assembly 35 is configured to provide an elastic force for moving the second connecting rod 34 and the third connecting rod 36 away from each other;

[0064] Specifically, as shown in Figure 1 , the operation of the probe rod T is described: when the operating rod 2 is pressed downward, the operating rod 2 drives the second slider 33 to move downward through the first connecting rod 32, at this time, the second connecting rod 34 and the first connecting rod 32 form an obtuse angle, the second slider 33 pushes the second connecting rod 34, and the second connecting rod 34 compresses the elastic preloading assembly 35, so that the elastic force exerted by the elastic preloading assembly 35 on the third connecting rod 36 increases, thus the pushing force of the third connecting rod 36 on the one-way clamping wheel assembly 4 increases, and the clamping force of the rollers 43 on the probe rod T increases, thereby improving the clamping stability of the two rollers 43 on the probe rod T, and facilitating the stable penetration of the probe rod T.

[0065] Similarly, as shown in Figure 8 , the operation of the probe rod T is described: at this time, the second connecting rod 34 and the first connecting rod 32 form an acute angle, when the second slider 33 rises, the second connecting rod 34 compresses the elastic preloading assembly 35, so that the elastic force exerted by the elastic preloading assembly 35 on the third connecting rod 36 increases, thus the pushing force of the third connecting rod 36 on the one-way clamping wheel assembly 4 increases, and the clamping force of the rollers 43 on the probe rod T increases, thereby improving the clamping stability of the two rollers 43 on the probe rod T, and facilitating the stable extraction of the probe rod T.

[0066] In some embodiments, in order to adjust the one-way rotation direction of the first roller 43 and the second roller 43, so as to switch the one-way friction wheel type probe rod loading device between the penetration operation state and the extraction operation state.

[0067] As shown in Figures 5-7As shown, the elastic preload assembly 35 includes a cylinder 351, a spring 352, and an adjuster 353. The cylinder 351 has an internal cavity 3511. The first end of the cylinder 351 is fixedly connected to the second connecting rod 34, and the second end of the cylinder 351 is slidably connected to the third connecting rod 36, which extends into the cavity 3511 of the cylinder 351. The adjuster 353 is rotatably mounted on the cylinder 351. The adjuster 353 includes an adjusting block 3531 and a screwing part 3532. The adjusting block 3531 is disposed within the cavity 3511 of the cylinder 351, and the screwing part 3532 is disposed outside the cylinder 351. The side of the adjusting block 3531 has at least one long end 3531b and at least one short end 3531a. The distance from the long end 3531b to the rotation axis of the adjusting block 3531 is greater than the distance from the short end 3531a to the rotation axis of the adjusting block 3531. The distance between the rotation axis of the adjusting block 3531 and the cylinder body 3531; by rotating the screwing part 3532, the short end 3531a or the long end 3531b of the adjusting block 3531 is axially aligned with the third connecting rod 36; the spring 352 is disposed in the cavity 3511 of the cylinder body 351, one end of the spring 352 is aligned with the third connecting rod 36, and the other end of the spring 352 is aligned with the adjusting block 3531; when the long end 3531b of the adjusting block 3531 is axially aligned with the third connecting rod 36, the distance between the long end 3531b of the adjusting block 3531 and the second end of the cylinder body 351 is less than or equal to the natural length of the spring 352; when the short end 3531a of the adjusting block 3531 is axially aligned with the third connecting rod 36, the distance between the short end 3531a of the adjusting block 3531 and the second end of the cylinder body 351 is greater than the natural length of the spring 352.

[0068] Specifically, in Figure 1 Penetration operation state or Figure 8 In the lifting operation state, the adjusting blocks 3531 all have their long ends 3531b axially corresponding to the third connecting rod 36, such as... Figure 7 As shown, at this time, the spring 352 and the third link 36 form a compression engagement. When the second link 34 pushes the cylinder 351, the cylinder 351 and the adjusting block 3531 move synchronously. The adjusting block 3531 compresses the spring 352, and the elastic force of the spring 352 on the third link 36 increases. In this way, the elastic preload component 35 can realize the function of providing elastic force to make the second link 34 and the third link 36 move away from each other.

[0069] When it is necessary to adjust the unidirectional rotation direction of the first roller 43 and the second roller 43, for example, when... Figure 1 The state changed to Figure 8In this state, the screwing part 3532 can be rotated so that the short end 3531a of the adjusting block 3531 aligns axially with the third connecting rod 36, such as... Figure 6 As shown, at this time, there is enough space inside the cylinder 351 for the spring 352 to extend naturally, and there is a certain distance between the spring 352 and the third link 36. After removing the limiting guide mechanism 5, the roller 43 can be moved away from the probe T, and the third link 36 moves axially closer to the second link 34. The third link 36 does not compress the spring 352 or the amount of compression of the spring 352 is very small, so that the resistance to the axial movement of the third link 36 is small, which facilitates operation. The overall length of the second link 34, the third link 36 and the roller 43 is shortened, so that the second link 34, the third link 36 and the roller 43 can be swung upward, so that the angle between the second link 34 and the first link 32 changes from an obtuse angle to an acute angle. In addition, the third link 36 is rotated 180° circumferentially, so that the first roller 43 and the second roller 43 are flipped, thereby changing the unidirectional rotation direction of the first roller 43 and the second roller 43.

[0070] In some embodiments, to improve the clamping stability of the roller 43 on the probe T, such as Figure 4 As shown, the outer peripheral wall of the roller 43 is provided with a groove 431 for holding the probe T, and the cross-section of the groove 431 has an arc-shaped inner wall profile. In this way, the probe T is difficult to detach from the two rollers 43.

[0071] Preferably, to increase the friction between the roller 43 and the probe T, thereby improving the stability of the probe T during penetration and extraction, such as... Figure 4 As shown, the inner wall of the wheel groove 431 is provided with a number of protruding structures 432, which can be strip-shaped, dot-shaped, etc.

[0072] In some embodiments, to reduce the workload of manual operations, such as Figure 1 As shown, the position from the first end of the operating lever 2 to the connection point between the operating lever 2 and the movable component 3 is defined as the first length segment L1; the position from the operating end 21 of the operating lever 2 to the connection point between the operating lever 2 and the movable component 3 is defined as the second length segment L2; the length of the second length segment L2 is greater than the length of the first length segment L1. Thus, the operating lever 2 utilizes the lever principle to drive the movable component 3 to rise and fall, requiring less effort.

[0073] In some embodiments, to improve the stability of the second slider 33 during lifting and lowering, such as Figure 1 As shown, the frame 1 is provided with two symmetrically distributed guide sleeves 11, and the second slider 33 is slidably disposed in the guide sleeve 11; in order to avoid interference between the second connecting rod 34 and the guide sleeve 11, a clearance groove (not shown) is provided on one side of the guide sleeve 11 for the second connecting rod 34 to pass through.

[0074] In addition, in order to improve the stability of the vertical lifting of the probe rod T, as shown in the drawings, the rack 1 is further provided with a guide hole 12 for sliding cooperation with the probe rod T. Figure 1

[0075] In the above embodiments, the description of each embodiment is focused on, and the part not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0076] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.​
