Technical Field
[0001] This invention relates to the field of static cone penetration testing technology, and more particularly to a tracked static cone penetration testing device with a shock-absorbing mechanism. Background Technology
[0002] Static cone penetration testing (CPPT) involves using a pressure device to press a probe with a probe tip into the test soil layer. A measurement system then measures the penetration resistance of the soil, allowing determination of certain fundamental physical and mechanical properties, such as the soil's deformation modulus and allowable bearing capacity. There are three methods of applying pressure for static cone penetration testing: mechanical, hydraulic, and manual. Static cone penetration tests are conducted in the field. Regression analysis of the specific penetration resistance (Ps) obtained from static cone penetration testing with relevant indicators from load tests and geotechnical tests yields empirical formulas applicable to specific regions or soil properties. These formulas can be used to calculate... To determine the natural bearing capacity of the soil foundation, tracked static cone penetration testing (PCT) equipment is used when conducting static cone penetration tests on test soil layers. Because multiple penetration tests are required at different locations, the probe rod is positioned at a relatively high height, which causes significant swaying during movement. Prolonged swaying can cause the parts related to the probe rod to shift, affecting the service life of the static cone penetration testing equipment. In addition, due to the different types of test soil layers, the probe rod often becomes covered with mud and impurities after penetration. Failure to clean it in time can affect the probe rod's ability to measure subsequent test soil layers. Summary of the Invention
[0003] To address the aforementioned problems in the existing technology, a tracked static cone penetration test device with an anti-vibration mechanism is provided.
[0004] The specific technical solution is as follows:
[0005] A tracked static cone penetration tester with a shock-absorbing mechanism includes a main body, a crossbar, and a fixed box. A telescopic rod is located above the main body, with an annular block at its upper end. The annular block is located on both sides of the crossbar. A second elastic element is located inside the crossbar, with a telescopic column at the end of the second elastic element away from the crossbar. A buffer pad is located on the side of the annular block away from the telescopic column, with first elastic elements on both sides of the buffer pad. The fixed box is located on one side of the main body, with a probe clamping rod above it. Inlets are located on both sides of the probe clamping rod, and a water tank is located below the inlets. A conduit is located on the side of the water tank near the probe clamping rod, with a cleaning block at the end of the conduit away from the water tank. A guide tube is located above the cleaning block, and a scraper is located below the fixed box.
[0006] Preferably, the main body of the static cone penetration device is fixedly connected to the telescopic rod, the telescopic rod is fixedly connected to the probe rod, the annular blocks are distributed on both sides of the telescopic rod, the first elastic element is evenly distributed, and the first elastic element is located between the annular blocks and fixedly connected to them.
[0007] Preferably, the crossbar has grooves at both ends, the second elastic element is located in the grooves at both ends of the crossbar and is fixedly connected to the crossbar, the second elastic element is fixedly connected to the telescopic column, and the telescopic column is fitted into the crossbar.
[0008] Preferably, the buffer pads are symmetrically distributed, the telescopic columns are fixedly connected to the annular blocks, and the annular blocks are fixedly connected to the buffer pads.
[0009] Preferably, the fixed box is fixedly connected to the main body of the static cone penetration test device, the probe rod passes through the fixed box and the guide tube, and the guide tube is located inside the fixed box and fixedly connected to its top.
[0010] Preferably, the cleaning blocks are symmetrically distributed on both sides of the probe rod, the cleaning blocks are located inside the fixed box, the conduit is fixedly connected to the cleaning blocks, the water tank is fixedly connected to the conduit, and the inlet extends through into the fixed box and is fixedly connected to the water tank.
[0011] Preferably, the scraper is penetrated by the probe rod, and the scraper is fixedly connected to the bottom of the fixed box.
[0012] The above technical solution has the following advantages or beneficial effects:
[0013] 1. By incorporating a crossbar and annular blocks, when the main body of the static cone penetrometer moves the telescopic rod, the rod swings to both sides, first contacting the buffer pad. The buffer pad cushions the telescopic rod. The first elastic element fixes the annular blocks to both sides of the telescopic rod, and the annular blocks are fixedly connected to the telescopic column, which is embedded in the crossbar. The second elastic element is located between the telescopic column and the crossbar and is fixedly connected to both, allowing the telescopic rod to move back and forth in the direction of the crossbar while remaining stable. The expansion and contraction cycle of the second elastic element significantly reduces the swing amplitude of the telescopic rod, avoiding the large swaying that would occur when moving the probe rod, which is at a relatively high height due to the need for multiple penetrations of the test soil layer in different directions. This reduces the swing amplitude of the telescopic rod, prevents the displacement of the probe rod and related parts, and extends the service life of the static cone penetrometer.
[0014] 2. By setting up a fixed box and a scraper, after the probe has completed its probe insertion, it moves upward under the action of the telescopic rod. When it passes the scraper, the scraper scrapes the soil and impurities carried by the probe and pushes them to the ground. At the same time, the guide tube inside the fixed box performs preliminary wiping and cleaning of the fixed box, avoiding the problem that the probe may affect the subsequent measurement of the soil layer due to failure to clean in time.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.
[0024] Reference Figure 1-4A tracked static cone penetration tester with a shock-absorbing mechanism includes a static cone penetration tester body 1, a crossbar 2, and a fixed box 3. A telescopic rod 4 is located above the static cone penetration tester body 1, with an annular block 5 at its upper end. The annular block 5 is located on both sides of the crossbar 2. A second elastic element 11 is located inside the crossbar 2, with a telescopic column 9 at the end of the second elastic element 11 away from the crossbar 2. A buffer pad 10 is located on the side of the annular block 5 away from the telescopic column 9, with first elastic elements 8 on both sides of the buffer pad 10. The fixed box 3 is located on one side of the static cone penetration tester body 1. A probe 6 is located above the fixed box 3, with inlets 7 on both sides of the probe 6. A water tank 15 is located below the inlets 7, with a conduit 14 on the side of the water tank 15 near the probe 6. A cleaning block 12 is located at the end of the conduit 14 away from the water tank 15, with a guide tube 16 above the cleaning block 12. A scraper 13 is located below the fixed box 3. By setting up a crossbar 2 and annular block 5, when the main body 1 of the static cone penetration test device moves the telescopic rod 4, the telescopic rod 4 swings to both sides and first contacts the buffer pad 10. The buffer pad 10 cushions the telescopic rod 4. The first elastic element 8 fixes the annular block 5 to both sides of the telescopic rod 4. The annular block 5 is fixedly connected to the telescopic column 9, which is embedded in the crossbar 2. The second elastic element 11 is located between the telescopic column 9 and the crossbar 2 and is fixedly connected to both. This allows the telescopic rod 4 to move back and forth in the direction of the crossbar 2. The telescopic cycle of the second elastic element 11 greatly reduces the swing amplitude of the telescopic rod 4, avoiding the large swaying that would occur when moving the probe rod 6, which is at a high height, due to the need to conduct multiple penetrations of the test soil layer in different directions. This reduces the swing amplitude of the telescopic rod 4, prevents the displacement of the parts related to the probe rod 6, and extends the service life of the static cone penetration test device.
[0025] Furthermore, the main body 1 of the static cone penetration test device is fixedly connected to the telescopic rod 4, the telescopic rod 4 is fixedly connected to the probe rod 6, the annular blocks 5 are distributed on both sides of the telescopic rod 4, the first elastic element 8 is evenly distributed, the first elastic element 8 is located between the annular blocks 5 and fixedly connected to them, the first elastic element 8 is used to connect the annular blocks 5 on both sides of the telescopic rod 4, under the action of the first elastic element 8, the annular blocks 5 can be stably fixed at the upper end of the telescopic rod 4, and at the same time the first elastic element 8 limits the swing amplitude of the telescopic rod 4, making it more stable.
[0026] Furthermore, grooves are provided at both ends of the crossbar 2, and the second elastic element 11 is located in the grooves at both ends of the crossbar 2 and is fixedly connected to the crossbar 2. The second elastic element 11 is fixedly connected to the telescopic column 9, and the telescopic column 9 is fitted into the crossbar 2. The telescopic column 9 is embedded in the crossbar 2, and the second elastic element 11 is located between the telescopic column 9 and the crossbar 2 and is fixedly connected to both of them, so that the telescopic rod 4 moves back and forth in the direction of the crossbar 2. The swing amplitude of the telescopic rod 4 is greatly reduced by the telescopic cycle of the second elastic element 11.
[0027] Furthermore, the buffer pads 10 are symmetrically distributed, the telescopic column 9 is fixedly connected to the annular block 5, the annular block 5 is fixedly connected to the buffer pads 10, the buffer pads 10 are made of soft material, the soft buffer pads 10 absorb the force generated by the swing of the telescopic rod 4, buffer the telescopic rod 4, and at the same time increase the friction between the annular block 5 and the telescopic rod 4, so that the annular block 5 is more stably fixed on the telescopic rod 4.
[0028] Furthermore, the fixed box 3 is fixedly connected to the main body 1 of the static cone penetration test device, and the probe rod 6 passes through the fixed box 3 and the guide tube 16. The guide tube 16 is located inside the fixed box 3 and fixedly connected to its top. The bottom end of the guide tube 16 is shallowly submerged into the top of the cleaning block 12, so that the probe rod 6 can enter the cleaning block 12 and ensure that the cleaning block 12 can clean it when the probe rod 6 rises.
[0029] Furthermore, cleaning blocks 12 are symmetrically distributed on both sides of the probe rod 6. The cleaning blocks 12 are located inside the fixed box 3. The conduit 14 is fixedly connected to the cleaning blocks 12. The water tank 15 is fixedly connected to the conduit 14. The inlet 7 extends through and into the fixed box 3 and is fixedly connected to the water tank 15. The inlet 7 is used to add liquid to the water tank 15. The conduit 14 is equipped with a liquid suction core to conduct the diluted cleaning agent in the water tank 15 to the cleaning blocks 12.
[0030] Furthermore, the scraper 13 is penetrated by the probe rod 6, and the scraper 13 is fixedly connected to the bottom of the fixed box 3. After the probe rod 6 completes its probe, it moves upward under the action of the telescopic rod 4. When passing the scraper 13, the scraper 13 scrapes the soil and impurities carried by the probe rod 6, scraping large particles such as soil and impurities to the ground.
[0031] Working principle: When using this device, gently separate the annular block 5 and slip it onto the upper end of the telescopic rod 4. The first elastic element 8 located between the annular blocks 5 contracts, fixing the annular block 5 onto the telescopic rod 4. When the main body 1 of the static probe device moves the telescopic rod 4, the telescopic rod 4 swings to both sides, first contacting the buffer pad 10. The soft buffer pad 10 absorbs the force generated by the swing of the telescopic rod 4, cushioning the telescopic rod 4. The annular block 5 is fixedly connected to the telescopic column 9, which is embedded in the crossbar 2. The second elastic element 11 is located between the telescopic column 9 and the crossbar 2 and is fixed to both. The fixed connection allows the telescopic rod 4 to reciprocate in the direction of the crossbar 2. The telescopic cycle of the second elastic element 11 greatly reduces the swing amplitude of the telescopic rod 4. After the probe 6 completes its probe test, it moves upward under the drive of the telescopic rod 4. When it passes the scraper 13, the scraper 13 scrapes the soil and impurities carried by the probe 6 and pushes them to the ground. At the same time, the guide tube 16 located inside the fixed box 3 performs preliminary wiping and cleaning of the fixed box 3, avoiding the problem that the probe 6 may affect the subsequent measurement of the test soil layer if it is not cleaned in time.
[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
