[0001] The present application relates to the field of geotechnical engineering investigation equipment, and in particular to an automatic clamping rod device for static penetration equipment. Background Art
[0002] Static penetration testing is an important geological exploration method that uses a pressure device to press a penetration rod with a probe head into the test coating.
[0003] The rod clamping device is a key part of the penetration equipment, which is used to fix and stabilize the probe rod during the penetration process. In the related art, the automatic rod clamping device drives the automatic clamp to clamp the probe rod through the movement of the piston rod of the hydraulic cylinder. When the probe rod needs to be released, the reversing valve is operated to change the oil inlet direction of the hydraulic cylinder, so that the piston rod can move in the opposite direction to release the clamp of the automatic clamp on the probe rod. The structure is complex and the manufacturing cost is high, which needs to be improved. Utility Model Content

[0006] By adopting the above technical solution, during the experiment, the mounting seat is fixed, the probe rod is passed through the guide cylinder, and during the penetration of the probe rod, the guide cylinder is moved downward, so that a number of slips move closer to each other along the guide surface and press against the probe rod, so that the probe rod remains stable during the penetration process. The slips can loosen the probe rod by moving the guide cylinder upward, and the loosening and clamping of the probe rod can be achieved through a unique mechanical structure, which is conducive to reducing the setting of the power source and reducing costs.
[0007] Preferably, a plurality of the slips slide into or out of the longitudinal through hole.
[0008] By adopting the above technical solution, during the experiment, when the cava is moved, it disengages from the longitudinal through hole. After the probe rod passes through the longitudinal through hole, the gap between the longitudinal through hole of the cava and the probe rod is narrowed, so that the cava is pressed against the probe rod along the guide surface. This is conducive to placing the cava through the through hole, and the cava is not located on the penetration path of the probe rod, which facilitates the penetration of the probe rod.
[0009] Preferably, the guide cylinder includes a cylinder body slidably connected to the mounting seat, a plurality of positioning rings detachably connected to the cylinder body, the longitudinal through hole and the guide surface are both provided on the cylinder body, the plurality of positioning rings are respectively located on opposite sides of the cylinder body, the positioning rings and the positioning rings are located on the cava path, and the positioning rings are used to abut the cava.

[0011] Preferably, the guide surface comprises an upper guide surface and a lower guide surface, the upper guide surface is tapered downward, the lower guide surface is tapered upward, and the upper guide surface and the lower guide surface are used to abut against a plurality of slips.
[0012] By adopting the above technical solution, when the probe rod penetrates, the lower guide surface abuts the slip, and the barrel moves downward to make the slip press against the probe rod. When the probe rod is taken out, the slip is taken out from the longitudinal channel and then inserted from the top of the barrel. Moving the barrel upward will make the slip press against the barrel, so that the probe rod remains stable during the removal and penetration process.
[0013] Preferably, an elastic member is provided on the guide cylinder, and the elastic member presses against the slip so that the slip has a tendency to move upward.
[0014] By adopting the above technical solution, during the experiment, the probe rod passes through the longitudinal through hole, and the slips press against the probe rod along the guide surface under the action of the elastic member, which is beneficial to improving the clamping efficiency of the probe rod.
[0015] Preferably, a magnetic component is provided on the slip, and the magnetic component is used to adsorb the probe rod. The magnetic component is located on a side of the slip close to the probe rod.
[0016] By adopting the above technical solution, when the probe rod is extended into the magnetic probe rod, a plurality of slips are arranged around the outer circumference of the probe rod, and the adsorption force of the magnetic member on the probe rod causes the slips to press against the probe rod, which is beneficial to improving the clamping efficiency.
[0017] Preferably, a sliding groove is provided on the guide cylinder, the mounting seat is inserted into the sliding groove, and the sliding groove passes through one end of the guide cylinder in a vertical direction.

The unique mechanical structure is used to loosen and clamp the probe rod, which is beneficial to reduce the setting of power source and reduce costs;
[0023] 2. By setting the lower guide surface and the upper guide surface, the probe rod can be kept stable during the extraction and penetration process;
[0024] 3. The positioning ring is used to abut the slip, so that the slip is not easy to separate from the cylinder body during the experiment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The present application is further described in detail below in conjunction with the accompanying drawings.
[0030] The embodiment of the present application discloses an automatic rod clamping device for static penetration equipment.
[0031] Example 1
[0032] Reference Figure 1 and Figure 2 An automatic clamping device for static penetration equipment includes a mounting seat 1 and a guide cylinder 2. The mounting seat 1 is arranged around the outer circumference of the guide cylinder 2, and the axis of the guide cylinder 2 is arranged vertically. A sliding groove 211 is opened on the outer wall of the guide cylinder 2. The sliding groove 211 penetrates the guide cylinder 2 downward in the vertical direction. The sliding groove 211 is for the mounting seat 1 to be clamped, and the mounting seat 1 is connected to the guide cylinder 2 by lifting and sliding.
[0033] Reference Figure 2The guide cylinder 2 includes a cylinder body 21 and a plurality of positioning rings 22. A longitudinal through hole 212 is provided on the cylinder body 21. The longitudinal through hole 212 is arranged around the axis of the cylinder body 21. The longitudinal through hole 212 is used for the probe to pass through. A guide surface 213 is formed on the inner wall of the longitudinal through hole 212. The guide surface 213 includes an upper guide surface 2131 and a lower guide surface 2132. The cross-sections of the upper guide surface 2131 and the lower guide surface 2132 in the horizontal direction are circular. The upper guide surface 2131 and the lower guide surface 2132 are distributed in the vertical direction. The upper guide surface 2131 is located below the lower guide surface 2132. The upper guide surface 2131 is gradually reduced downwardly, and the lower guide surface 2132 is gradually reduced upwardly. The upper guide surface 2131 and the lower guide surface 2132 have the same diameter at one end close to and far away from each other, and the upper guide surface 2131 and the lower guide surface 2132 are symmetrical to each other.
[0034] Reference Figure 1 and Figure 2 , a plurality of positioning rings 22 are respectively located on opposite sides of the barrel 21, a plurality of positioning rings 22 are distributed in the vertical direction, a plurality of positioning rings 22 are coaxial with the barrel 21, and the inner ring of the positioning ring 22 is located on the extension path of the longitudinal through hole 212. In this embodiment, the positioning ring 22 is detachably connected to the barrel 21 through threaded engagement with the barrel 21; in other embodiments, the positioning ring 22 can also be connected to the barrel 21 through screws, bolts, etc.
[0035] Reference Figure 2 A plurality of slips 3 are slidably connected to the barrel 21, and the plurality of slips 3 slide into or extend out of the longitudinal through hole 212. The length of the slips 3 in the vertical direction is less than the length of the upper guide surface 2131 or the lower guide surface 2132 in the vertical direction. When the probe rod passes through the longitudinal through hole 212, the plurality of slips 3 are arranged at intervals around the outer circumference of the probe rod. The plurality of positioning rings 22 are respectively located at the ends away from the upper guide surface 2131 and the lower guide surface 2132. The end of the slip 3 close to the probe rod fits the probe rod, and the end of the slip 3 away from the probe rod fits the lower guide surface 2132 or the upper guide surface 2131. The positioning ring 22 is located on the moving path of the slip 3. The positioning ring 22 is used to abut the slip 3 to limit the slip 3 to prevent the slip 3 from separating from the barrel 21 during the experiment.
[0036] In actual use, the mounting seat 1 is fixed to the sounding device, the positioning ring 22 below the barrel 21 is rotated to make the lower positioning ring 22 detach from the barrel 21, the slip 3 is taken out from the longitudinal through hole 212, the probe rod is penetrated through the longitudinal through hole 212 and the positioning ring 22, and then a number of slips 3 are put into the gap between the longitudinal through hole 212 and the probe rod, so that the opposite ends of the slips 3 distributed along the radial direction of the barrel 21 are respectively pressed against the probe rod and the lower guide surface 2132, and the lower positioning ring 22 is fixed to the barrel 21 to prevent the slips 3 from detaching from the longitudinal through hole 212. During the penetration process of the sounding device driving the probe rod to move downward, the barrel 21 is moved downward, so that the slips 3 move upward relative to the barrel 21, and the lower guide surface 2132 abuts against a number of slips 3 so that the slips 3 are pressed against the probe rod, so that the probe rod remains stable during the penetration process. When the probe rod needs to be unlocked, the barrel 21 is moved upward.
[0037] When taking out the probe rod, rotate the upper and lower positioning rings 22 to separate the positioning rings 22 from the barrel 21, take the slips 3 out of the lower guide surface 2132 and put them into the longitudinal through hole 212 from the top, so that the slips 3 abut against the upper guide surface 2131, rotate the rings to fix the positioning rings 22 and the barrel 21, and when the barrel 21 is moved upward, the slips 3 abut against the probe rod, so that the probe rod is not easy to shake during the upward movement. When the probe rod needs to be unlocked, just move the barrel 21 downward.
[0038] It is convenient to keep the probe rod stable during the penetration and removal process.
[0039] Reference Figure 2 An elastic member 4 is fixed on the positioning ring 22 located below the barrel 21. The elastic member 4 extends into the longitudinal channel. The elastic member 4 is used to press against the slip 3 abutting against the lower guide surface 2132. The lower end of the elastic member 4 is fixed to the positioning ring 22, and the upper end of the elastic member 4 presses against the slip 3. The elastic member 4 is arranged around the periphery of the probe rod. The elastic member 4 presses against the slip 3 so that the slip 3 has a tendency to move upward, which is convenient for timely clamping the probe rod when the probe rod penetrates. In this embodiment, the elastic member 4 is a spring.
[0040] The implementation principle of Example 1 is: when in use, the probe rod can be loosened and tightened by moving the barrel 21, which makes the operation convenient; it is beneficial to reduce the installation of the driving source, has a simple structure, and is beneficial to reduce costs.
[0041] Example 2
[0042] Reference Figure 1 and Figure 3 , which is different from Embodiment 1 in that a magnetic member 5 is fixed to the side of the slip 3 away from the probe rod, and the magnetic member 5 can adsorb the probe rod, and the opposite ends of the magnetic member 5 distributed along the radial direction of the barrel 21 are respectively used to fit the end of the slip 3 away from the probe rod and the lower guide surface 2131 or the upper guide surface 2132, so that the slip 3 is pressed against the probe rod under the adsorption force of the magnetic member 5 on the probe rod. In this embodiment, the magnetic member 5 is a magnet.
[0043] The implementation principle of Example 2 is: when the slip 3 is inserted into the gap between the lower guide surface 2132 and the probe rod, the slip 3 is pressed against the probe rod through the magnetic part 5, and it is not easy to fall out of the gap between the lower guide surface 2132 and the probe rod, making the installation of the barrel 21, the slip 3 and the positioning ring 22 more convenient.
