Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sand removal on a probe rod, and more specifically, to a device for removing sand from a probe rod. Background Art
[0002] The onshore static penetration test is a method of in-situ testing, usually performed using a static penetration machine. During the test, the probe rod holder is controlled, usually an upper and lower hydraulic clamp, to drive the probe rod down or up. When the probe rod is pulled up, the guide shoe will be detached from the circular hole on the vehicle floor equipped with the static penetration machine because there is no pressure on the upper part, making it impossible to remove the sand and soil on the probe rod. Part of the sand and soil brought into the vehicle by the probe rod will be blown into the hydraulic cylinder. Over time, the cylinder oil seal will be damaged, causing oil leakage in the cylinder, a drop in pressure, and the inability to carry out testing. Another part of the sand and soil will be blown onto the interior of the static penetration vehicle, affecting the internal environment of the vehicle. To solve the above problems, the following two methods are usually adopted in the prior art: the first method is to put a steel wool on the outside of the probe rod and below the bottom of the probe rod clamp; this method has a good effect in removing sand from the probe rod, but the disadvantage is that the steel wool is very flexible and will enter the inside of the probe rod clamp as the probe rod is pulled up, and will be damaged by the clamping force of the probe rod clamp. Multiple steel wools need to be replaced for each detection point, and the steel wools are frequently replaced and used in large quantities; the second method is to wrap a rope around the probe rod, and the end of the rope is fixed to the leg of the probe rod clamp; this method causes the rope to be squeezed into the inside of the probe rod clamp due to the excessive pulling force on the probe rod, causing the rope to be damaged. The implementation of the above two methods has not effectively solved the problem of removing sand from the probe rod, and there is an urgent need to find a method for removing sand from the probe rod with good effect and low cost.

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
[0018] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0019] like Figure 1 As shown, the utility model provides a device for removing sand from a probe rod, which is arranged below a probe rod holder of a static penetration machine, and comprises a column 1 and a guide shoe 3; the column 1 is sleeved on the outer periphery of the probe rod, and the two ends are respectively abutted against the probe rod holder and the guide shoe 3; the column 1 is formed by two semicircular steel columns 11 that are detachably connected; the cross-section of the guide shoe 3 is a circular ring, the inner diameter of which matches the diameter of the probe rod, and the outer diameter is larger than the diameter of the column 1.
[0020] In this technical solution, the length of the column 1 is determined by the distance between the bottom surface 4 of the probe rod holder and the top surface of the guide shoe 3, so that the two ends of the column 1 are respectively in contact with the probe rod holder and the guide shoe 3. The guide shoe 3 is used to limit the probe rod to ensure that the probe rod is located at the center of the circular hole 5 on the vehicle floor. After the detection is completed, before the probe rod is recovered, the two steel columns 11 are symmetrically placed on the outside of the probe rod and connected to form the column 1, and the bottom surface 4 of the probe rod holder and the top surface of the guide shoe 3 are respectively supported from top to bottom to ensure that the guide shoe 3 will not be separated from the circular hole 5 on the vehicle floor equipped with the static penetration tester due to the upward pulling force of the probe rod. When the probe rod is recovered, the column 1 and the guide shoe 3 are disassembled and removed, and the probe at the top of the probe rod is taken out. During the above process, the column 1 and the guide shoe 3 ensure that the sand and soil on the probe rod will not enter the vehicle and the interior of the static penetration machine through the circular hole 5 in the vehicle floor and the guide shoe 3 during the recovery of the probe rod, thereby protecting the hydraulic cylinder from oil leakage due to sand and soil sticking to the wall, making it impossible to carry out the test work, and at the same time reducing the sand and soil from entering the interior of the static penetration vehicle and contaminating the interior.
[0021] In another technical solution, Figure 2As shown, the inner wall of the steel column 11 is fixedly provided with a plurality of vertically arranged reinforcing ribs 12, and the plurality of the reinforcing ribs 12 are arranged at equal intervals along the circumference of the steel column 11. The strength of the steel column 11 is strengthened by the reinforcing ribs 12, ensuring that the column 1 will not be deformed during the process of pulling up the probe rod, thereby causing the guide shoe 3 to be separated from the circular hole 5 on the vehicle floor, affecting the effect of removing sand and soil on the probe rod.
[0022] In another technical solution, Figure 1 As shown, at least two hoops 2 are arranged on the periphery of the column 1, and the hoops are arranged at intervals along the vertical direction. The hoops 2 are used to fix or loosen the two steel columns 11.
[0023] Furthermore, the hoop 2 is a stainless steel throat hoop. Figure 3 As shown, the stainless steel throat clamp includes a hoop band 21, a fastening bolt 22, and a connecting piece 23. The hoop band 21 is circular, and the diameter of the circle can be adjusted as needed, and the diameter of the circle is greater than or equal to the outer diameter of the column 11. The fastening bolt 22 is used to clamp or loosen the hoop ring 21. The connecting piece 23 is used to connect the fastening bolt 22 and the hoop band 21.
[0024] In another technical solution, Figure 4 As shown, the two sides of the steel column 11 are provided with a docking portion 13, and the docking portion 13 is provided with a bolt hole, and the docking portions of the two steel columns 11 are fixedly connected by bolts. The docking portion 13 is used to achieve the detachable docking of the two steel columns 11.
[0025] In another technical solution, the centers of the column 1 and the guide shoe 3 are in a straight line. When the probe rod is pulled up, the force on the column 1 can be evenly applied to the contact surface between the column 1 and the guide shoe 3, thereby preventing the column 1 from deforming due to uneven force.
[0026] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
