Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a static cone penetration test device for foundation bearing capacity. Background Art

[0002] In the field of modern construction engineering, as the foundation of the entire building, the bearing capacity of the foundation is directly related to the stability and safety of the building. Whether it is a towering skyscraper, a large-scale bridge project, or various infrastructure constructions, strict requirements are imposed on the bearing capacity of the foundation. Accurately measuring the foundation bearing capacity is a key link in the geological exploration work in the early stage of engineering construction, and it has inestimable significance for reasonably designing the foundation form, ensuring the project quality, and controlling the project cost.

[0003] In the prior art, when detecting the bearing capacity of the foundation, a static cone penetration test device is required. The cone penetrometer is driven by a power device to move uniformly into the soil layer. With the cooperation of various sensors such as a resistance sensor and a friction sensor installed in the cone penetrometer, various data in the soil layer can be collected and transmitted to an external detection device for detection, so as to judge the bearing capacity of the foundation. However, when detecting the bearing capacity of the foundation traditionally, the static cone penetration test device is directly placed on the ground and then detected, and the device cannot be kept horizontal. When detecting complex terrains, the static cone penetration test device will tilt, resulting in the cone penetrometer tilting into the soil layer during the foundation detection process. This will not only seriously affect the accuracy of the foundation bearing capacity detection result, but also cause damage to the cone penetrometer when it penetrates into the soil layer, increasing the cost consumption. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. During the use of the present invention, when the static cone penetration test device reaches the designated position to detect the bearing capacity of the foundation, first, with the cooperation of the electronic tilt sensor and the external detection device, the balance state of the static cone penetration test device can be detected. When it is detected that the static cone penetration test device is greatly tilted due to the terrain, the external controller will send out corresponding control signals to control the first telescopic rod and the second telescopic rod at the corresponding positions to work. With the cooperation of structures such as the first adjustment column, the second adjustment column, and the rollers, the balance state of the static cone penetration test device is adjusted correspondingly, so that the probe rod and the probe head are perpendicular to the ground, which is more convenient for subsequent detection of the bearing capacity of the foundation, improves the accuracy of the detection results, avoids damage to the probe head when it penetrates into the soil layer, and greatly reduces the cost consumption.

[0017] 2. During the use of the present invention, after the static cone penetration test device completes the balance adjustment, under the action of structures such as the second motor, the lead screw, and the third motor, the drill pipe is driven to move downward into the ground. Then, under the action of the third telescopic rod, the connecting block is driven to move downward. With the cooperation of the connecting plate, the positioning block moves to both sides inside the limit box and inserts into the soil layer, thereby fixing the entire static cone penetration test device. This can prevent the static cone penetration test device from shifting and tilting during the subsequent bearing capacity detection process due to excessive downward force of the probe rod and the probe head, making it more convenient for subsequent detection of the foundation and further avoiding damage to the probe rod and the probe head during use.

[0018] 3. During the use of the present invention, after the static cone penetration test device completes the balance adjustment and fixation, under the action of the hydraulic cylinder, the mounting plate, the probe rod, and the touch probe are driven to move downward into the soil layer. During this process, through the tip resistance sensor and the sidewall friction sensor inside the touch probe, data on the resistance and friction during the movement of the touch probe can be collected and transmitted to the external detection device, enabling the bearing capacity of the foundation at this position to be understood. After the detection is completed, when the touch probe is driven upward by the hydraulic cylinder, under the cooperation of the fourth motor, the first bevel gear, and the second bevel gear, the probe rod and the spiral blade can be driven to rotate, thereby preventing the loose soil on the inner wall of the exploration hole from affecting the touch probe during the upward movement, making it more convenient to take out the touch probe and greatly improving the use effect.

[0033] Example 1, referring to Figures 1-10 As shown in the figure: The present invention provides a static cone penetration test device for foundation bearing capacity, including an adjustment mechanism 1. A fixing mechanism 2 and a main test mechanism 3 are arranged at the top of the adjustment mechanism 1;

[0034] The adjusting mechanism 1 includes a carrier plate 11 and four groups of adjusting components respectively fixed at the four corners of the carrier plate. Each group of adjusting components includes a mounting box 12 arranged on the side surface of the carrier plate. A set of embedding grooves 121 are opened on the inner walls of the four mounting boxes 12. A movable block 122 is movably embedded between the inner walls of the four groups of embedding grooves 121. A first fixing block 13 is fixedly installed at the top of the four movable blocks 122. A first telescopic rod 131 is movably sleeved on the outer surfaces of the four first fixing blocks 13. A first adjusting column 132 is movably sleeved on the outer surfaces of the four movable blocks 122. A second fixing block 133 is fixedly installed on one side of the outer walls of the four first adjusting columns 132, and the second fixing block 133 is movably connected with the telescopic end of the first telescopic rod 131. A first limiting block 134 is fixedly installed on one side of the outer walls of the four first adjusting columns 132. A second telescopic rod 135 is movably sleeved on the outer surfaces of the four first limiting blocks 134. A second adjusting column 136 is movably sleeved on the outer surfaces of the four first adjusting columns 132. A second limiting block 137 is fixedly installed on one side of the outer walls of the four second adjusting columns 136, and the outer surface of the second limiting block 137 is movably connected with the telescopic end of the second telescopic rod 135. An electronic tilt sensor 15 is fixedly installed at the bottom of the carrier plate 11. Three circular grooves 111 are opened on the top of the carrier plate 11. A storage battery 112 is fixedly installed on the top of the carrier plate 11. A piezoelectric ceramic sheet 123 is fixedly installed at the bottom of the four movable blocks 122. A buffer spring 124 is fixedly installed at the bottom of the inner walls of the four mounting boxes 12, and the top of the buffer spring 124 is fixedly connected with the bottom of the piezoelectric ceramic sheet 123. A damper 125 is arranged on the inner walls of the four buffer springs 124. A square groove 138 is opened on one side of the outer walls of the four second adjusting columns 136. A first motor 14 is fixedly installed on one side of the inner walls of the four square grooves 138. A first gear 141 is fixedly sleeved on the output ends of the four first motors 14. A roller 142 is movably inserted into the inner walls of the four second adjusting columns 136. A second gear 143 is fixedly sleeved on the rotating shafts of the four rollers 142, and the outer surface of the second gear 143 is meshed with the outer surface of the first gear 141.

[0035] In this embodiment, when it is necessary to use the static cone penetration test device to detect the bearing capacity of the foundation, first, under the action of the first motor 14, the first gear 141 is driven to rotate. At the same time, under the cooperation of the second gear 143, the roller 142 is driven to rotate, so as to drive the static cone penetration test device to move to a suitable position. During the movement of the static cone penetration test device, due to the terrain, the static cone penetration test device will vibrate, causing the movable block 122 to move inside the embedding groove 121, exerting a certain pressure on the buffer spring 124 to compress it. At the same time, when the piezoelectric ceramic sheet 123 is subjected to pressure, the lattice inside it deforms, resulting in a change in polarization intensity, and bound charges are generated on the surface. The charges are collected through the electrodes to form a voltage, which is input into the internal of the storage battery 112 through the wire harness to supply power to the electronic components in the static cone penetration test device. When the buffer spring 124 is compressed to a certain extent, a large rebound force will be generated. At this time, under the action of the damper 125, part of the rebound force can be absorbed, so as to achieve a shock absorption effect on the static cone penetration test device. After the static cone penetration test device moves to the designated position, under the action of the electronic tilt sensor 15 and the external detection device, the balance of the static cone penetration test device can be detected. When it is detected that the static cone penetration test device is tilted, the controller inside the detection device will send a control signal to control the first telescopic rod 131 and the second telescopic rod 135 to work. With the cooperation of the first adjustment column 132, the second adjustment column 136, and the roller 142, the balance state of the static cone penetration test device can be adjusted until it maintains a horizontal state, which is more convenient for subsequent detection of the bearing capacity of the foundation.

[0036] Embodiment 2, according to Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown in the figure, the fixing mechanism 2 includes two mounting brackets 21. At the top of both mounting brackets 21, a second motor 211 is fixedly installed. On the inner walls of both mounting brackets 21, a set of movable grooves 212 are opened. Between the inner walls of the two sets of movable grooves 212, mounting blocks 213 are movably embedded. On the inner walls of both mounting blocks 213, lead screws 214 are threadedly connected, and the outer surface of the lead screw 214 is fixedly connected to the output end of the second motor 211. On one side of the outer walls of both mounting blocks 213, a third motor 22 is fixedly installed. On the output ends of both third motors 22, a first transmission wheel 221 is fixedly sleeved. In the inner walls of both mounting blocks 213, drill rods 23 are movably inserted. On the outer surfaces of both drill rods 23, a second transmission wheel 231 is fixedly sleeved, and the outer surface of the second transmission wheel 231 meshes with the outer surface of the first transmission wheel 221. On the inner walls of both drill rods 23, a set of fixing rods 24 are fixedly installed. Between the outer surfaces of the two sets of fixing rods 24, a third telescopic rod 241 is fixedly installed. On the telescopic ends of both third telescopic rods 241, a connecting block 242 is fixedly installed. On the outer surfaces of both connecting blocks 242, two connecting plates 243 are movably connected. At the bottom of the inner walls of both drill rods 23, a limit box 244 is fixedly installed. In the inner walls of both limit boxes 244, two positioning blocks 245 are movably embedded, and the outer surface of the positioning block 245 is movably connected to the inner surface of the connecting plate 243.

[0037] In this embodiment, when the static cone penetration test device completes the horizontal state adjustment, under the action of the second motor 211, the lead screw 214 is driven to rotate, thereby driving the mounting block 213 to move downward inside the movable groove 212. At the same time, under the action of the third motor 22, the first transmission wheel 221 is driven to rotate, and with the cooperation of the second transmission wheel 231, the drill rod 23 can be driven to rotate, so that the drill rod 23 penetrates into the soil layer. When the drill rod 23 reaches an appropriate depth in the soil layer, under the action of the third telescopic rod 241, the connecting block 242 can be driven to move downward. Since a round shaft is fixedly installed inside the notch on the outer surface of the positioning block 245, the connecting plate 243 is movably sleeved on the surface of the round shaft, and the connecting plate 243 will maintain a certain inclination angle. Therefore, by the downward movement of the connecting block 242, under the action of the connecting plate 243, the positioning block 245 can be pushed to move to both sides inside the limit box 244, so that it is inserted into the soil layer, thereby playing a fixing role for the drill rod 23 and the static cone penetration test device, avoiding tilting during the subsequent foundation bearing capacity detection, and greatly improving the detection effect of the static cone penetration test device on the foundation bearing capacity.

[0038] Embodiment 3, according to Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, the main body testing mechanism 3 includes a fixing frame 31. A hydraulic cylinder 311 is fixedly installed on the inner wall of the fixing frame 31. An installation plate 32 is movably embedded between the inner walls of the fixing frame 31. The top of the installation plate 32 is fixedly connected to the telescopic end of the hydraulic cylinder 311. A fourth motor 321 is fixedly installed on the top of the installation plate 32. A first bevel gear 322 is fixedly sleeved on the output end of the fourth motor 321. An insertion slot 33 is formed on the top of the installation plate 32. A probe rod 331 is movably inserted into the inner wall of the insertion slot 33. A second bevel gear 332 is fixedly sleeved on the outer wall of the probe rod 331. The outer wall of the second bevel gear 332 meshes with the outer wall of the first bevel gear 322. A spiral blade 333 is fixedly installed on the outer wall of the probe rod 331. A touch probe head 334 is movably connected to the inner wall of the probe rod 331. The top of the carrier plate 11 is fixedly connected to the bottom of the installation frame 21. The top of the carrier plate 11 is fixedly connected to the bottom of the fixing frame 31. The outer walls of the two drill rods 23 are arranged inside two of the circular grooves 111. The outer wall of the probe rod 331 is arranged inside another one of the circular grooves 111.

[0039] In this embodiment, when the static cone penetration testing device completes balance adjustment and fixation, under the action of the hydraulic cylinder 311, the installation plate 32 can be driven to move downward inside the fixing frame 31, and the probe rod 331 and the touch probe head 334 are driven to move downward, so that the touch probe head 334 penetrates into the soil layer. When the touch probe head 334 moves inside the soil layer, the resistance and friction during the movement can be collected by the cone tip resistance sensor and the side wall friction sensor inside it and transmitted to the external detection system, so as to judge the bearing capacity of the foundation at this position. After the bearing capacity detection is completed, under the action of the hydraulic cylinder 311, the probe rod 331 and the touch probe head 334 are driven to move upward. During this process, under the cooperation of the fourth motor 321, the first bevel gear 322 and the second bevel gear 332, the probe rod 331 and the spiral blade 333 can be driven to rotate. Since the touch probe head 334 is rotatably connected to the probe rod 331, and the touch probe head 334 is in full contact with the inner wall of the exploration hole and generates friction, when the probe rod 331 rotates and drives the touch probe head 334 to penetrate into the soil layer, the touch probe head 334 will not rotate. Through the rotation of the spiral blade 333, the loosened soil can be taken out to avoid damage to the touch probe head 334 during the upward movement, greatly improving the use effect of the static cone penetration testing device.

[0040] The working principle of the whole mechanism is as follows: When it is necessary to use the static cone penetration test device to detect the bearing capacity of the foundation, first, under the action of the first motor 14, the first gear 141 is driven to rotate. At the same time, with the cooperation of the second gear 143, the roller 142 is driven to rotate, thereby driving the static cone penetration test device to move to a suitable position. During the movement of the static cone penetration test device, due to the terrain, the static cone penetration test device will vibrate, causing the movable block 122 to move inside the embedding groove 121, exerting a certain pressure on the buffer spring 124 to compress it. At the same time, when the piezoelectric ceramic sheet 123 is subjected to pressure, the lattice inside it deforms, resulting in a change in polarization intensity, and bound charges are generated on the surface. The charges are collected through the electrodes to form a voltage and input into the storage battery to supply power to the electronic components in the static cone penetration test device. When the buffer spring 124 is compressed to a certain extent, a large rebound force will be generated. At this time, under the action of the damper 125, part of the rebound force can be absorbed, thereby achieving a shock-absorbing effect on the static cone penetration test device. When the static cone penetration test device moves to the designated position, under the action of the electronic tilt sensor 15 and the external detection device, the balance of the static cone penetration test device can be detected. When it is detected that the static cone penetration test device is tilted, the controller inside the detection device will send a control signal to control the operation of the first telescopic rod 131 and the second telescopic rod 135. With the cooperation of the first adjustment column 132, the second adjustment column 136, and the roller 142, the balance state of the static cone penetration test device can be adjusted until the probe rod 331 and the cone tip 334 are perpendicular to the ground. Then, under the action of the second motor 211, the lead screw 214 is driven to rotate, thereby driving the mounting block 213 to move downward inside the movable groove 212. At the same time, under the action of the third motor 22, the first transmission wheel 221 is driven to rotate, and with the cooperation of the second transmission wheel 231, the drill rod 23 can be driven to rotate, enabling the drill rod 23 to penetrate into the soil layer. When the drill rod 23 reaches the appropriate depth in the soil layer, under the action of the third telescopic rod 241, the connecting block 242 can be driven to move downward. At the same time, under the action of the connecting plate 243, the positioning block 245 is pushed to move to both sides inside the limiting box 244, inserting it into the soil layer, thereby playing a fixing role for the drill rod 23 and the static cone penetration test device to prevent tilting during subsequent foundation bearing capacity detection. After the static cone penetration test device completes the balance adjustment and fixation, under the action of the hydraulic cylinder 311, the mounting plate 32 can be driven to move downward inside the fixing frame 31, and the probe rod 331 and the cone tip 334 are driven to move downward, enabling the cone tip 334 to penetrate into the soil layer. When the cone tip 334 moves inside the soil layer, the cone tip resistance sensor and the sidewall friction sensor inside it can collect data on the resistance and friction during movement and transmit them to the external detection system, thereby judging the bearing capacity of the foundation at this position. After completing the bearing capacity detection, under the action of the hydraulic cylinder 311,Drive the probe rod 331 and the probe head 334 to move upward. During this process, through the cooperation of the fourth motor 321, the first bevel gear 322 and the second bevel gear 332, the probe rod 331 and the spiral blade 333 can be driven to rotate. Since the probe head 334 is in full contact with the inner wall of the exploration hole, under the action of friction, the probe head 334 will not rotate. Through the rotation of the spiral blade 333, the loosened soil can be taken out, avoiding damage to the probe head 334 during the ascending process, thereby completing the bearing capacity detection of the foundation at this position.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
