Description

Technical Field

[0001] The utility model relates to the technical field of foundation detection equipment, in particular to an electric light-duty dynamic penetration device. Background Art

[0002] The light dynamic probing device is a device used for geological survey and detection of foundation bearing capacity. It has been widely used in the field of foundation detection. The traditional light dynamic probing device mainly includes a probing rod, a heavy hammer, a gasket and other components. When the light dynamic probing device is used, the staff will first place the probing rod at the location to be detected and install the heavy hammer. One staff member manually holds the vertical pole to keep the probing rod vertical. Two staff members lift the weight upwards and let go after lifting it to a certain height. The weight falls down quickly under the action of its own gravity and impacts the gasket, so that the probing rod can be pressed into the ground. A staff member can detect the bearing capacity of the foundation by recording the number of hammer strikes when the probing rod drops to a certain depth. It is found in the use of the existing light dynamic probing device that multiple staff members are required to complete the work together, which makes the labor intensity of the staff members high, resulting in poor convenience of use, and there is a risk of injury when holding the probing rod by hand. Moreover, each operation needs to be recorded manually, which is prone to omissions or errors, and the operation is cumbersome. At the same time, when the probe rod is stuck, it is difficult to pull it out by manpower.

[0003] Chinese patent CN201020650252.6 discloses a dynamic probing device, including a triangular bracket, in which a probe rod device is inserted; the triangular bracket includes three legs, the ends of the three legs are connected in a foldable manner, and the bottoms of the legs are respectively provided with scales; a sleeve is provided in the middle of the three legs, and a crossbeam that can be turned and closed is respectively connected between the three legs and the sleeve; the probe rod device includes a probe rod and a weight, a support is fixed on the probe rod, the bottom end of the probe rod is conical, the probe rod is inserted in the sleeve, and the weight is located above the support and inserted on the probe rod. This technology solves the problem that the probe rod needs to be held by hand during the probing process by cooperating with the triangular bracket and the probe rod, and the probing operation is highly safe, but this technology cannot solve the problem that the number of probings still needs to be manually recorded during the operation process and that the probe rod is difficult to pull out when it is stuck. Utility Model Content

[0004] In view of the shortcomings that the above-mentioned probing process requires manual recording of the number of probing times, which is cumbersome and easy to miss, and the probing rod is difficult to pull out when it gets stuck after probing, the utility model provides an electric light-weight power probing device which does not require a hand-held probing rod, is easy to operate, can automatically record the number of probing times, and can quickly and easily remove the probing rod when it is stuck after probing.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An electric light-duty power sounding device comprises a jack auxiliary support system, a sounding mechanism and a motor control system with a counter; the jack auxiliary system consists of a through-hole platform, a support rod and a jack, wherein a through hole is provided in the middle of the through-hole platform, a circular locking rod mechanism is connected to the top, the bottom surface is fixedly connected to the support rod, and the bottom of the support rod is fixedly connected to the jack; the sounding mechanism consists of a sounding rod and a through-hole gravity hammer, wherein the sounding rod can be movably inserted into the locking rod mechanism and the through-hole of the through-hole platform; a gasket is connected to the upper middle position of the sounding rod, and a drill bit is connected to the bottom; the through-hole gravity hammer is movably installed on the sounding rod above the gasket; the motor control system is fixedly arranged on the top of the sounding rod, and the motor control system is provided with a connecting rope, and the connecting rope is connected to the through-hole gravity hammer.

Since the transmission wheel B is fixedly connected to the rotating column, the rotating column and the pulley on the rotating column are driven to rotate, and then the connecting rope can be pulled up by the rotation of the pulley, and the connecting rope can pull up the through-hole gravity hammer, and then when the micro motor stops rotating, the through-hole gravity hammer will drop rapidly under the action of gravity; the transmission structure of the winding mechanism is simple, which is convenient for use and subsequent maintenance.

[0010] Furthermore, the locking rod mechanism is composed of a three-jaw chuck and an adjustment handle, wherein the handle is fixedly connected to an adjustment screw provided inside the three-jaw chuck; the bottom of the three-jaw chuck is fixed to the top of the through-hole platform, and the through hole of the three-jaw chuck corresponds to the through hole position of the through-hole platform. The three-jaw chuck can be selected from commercial products, which can facilitate the production and processing of the device and reduce production costs; the three-jaw chuck is away from the center of the claws in the normal state, and the locking rod mechanism is used by twisting the adjustment handle to adjust the three-jaw chuck through the adjustment handle so that the claws of the three-jaw chuck are retracted to clamp the probe rod, thereby realizing the connection between the jack auxiliary platform and the probe rod, and then the jack is controlled to extend to lift the support rod, and then the through-hole platform and the probe rod are pushed upward by the support rod, so that the probe rod of the stuck rod is pulled out, which is convenient for the displacement or recovery of the device.

[0011] Furthermore, there are three support rods, which are evenly distributed on the bottom surface of the through-hole platform, and the angle between every two support rods is 120°.

[0015] A method for using an electric light power penetration device comprises the following steps:

[0016] Step 1: Select a test point according to the on-site construction conditions and remove the loose soil on the surface and around the test point;

[0017] Step 2: Install the jack auxiliary support system. The jack at the bottom of the support rod is supported on the ground around the test point, and the through-hole platform is horizontally set just above the contact probe test point. The central through hole of the through-hole platform needs to be adjusted to be perpendicular to the ground. When performing the contact probe test, the locking rod mechanism of the through-hole platform remains loosened.

[0018] Step 3: Install the sounding mechanism with the motor system. After the sounding rod of the sounding mechanism passes through the penetration platform, the motor control system at the top of the sounding rod pulls the penetration gravity hammer to the top of the sounding rod. At this time, the drill bit at the bottom of the sounding rod is against the touch detection test point;

[0019] Step 4: Conduct a penetration test. First, control the motor control system to keep the hammering rate at 15-30 hits / min. Then turn on the motor control system. When the motor control system starts, the counter will automatically start to record the number of penetrations.

[0020] Step 5: Start a single penetration test. The motor control system drives the connecting rope to pull the core-penetrating gravity hammer up to the top of the probe rod and then release it. The core-penetrating gravity hammer moves down quickly along the probe and hits the gasket. The gasket is subjected to a downward force, which drives the probe rod and the drill bit to move downward at the same time. The drill bit drills into the test point for penetration, thus completing the single penetration test.

[0021] Step 6: Repeat the single probe test in step 5 until a probe rod reaches the required probe depth and then turn off the motor control system. At this time, the number of probes can be recorded through the counter;

[0022] Step 7: Import the data recorded by the counter into the linear regression formula preset in the computer, then select the appropriate working condition according to the site to select the foundation bearing capacity, and obtain the corresponding foundation bearing capacity by recording. The foundation bearing capacity obtained can complete the test data of dynamic penetration;

[0023] Step 8: Finally, disassemble the probe device. First, pull out the probe mechanism with the motor system from the through-hole platform. If the probe rod is successfully pulled out, then disassemble the jack auxiliary support system. The probe test operation ends here. If the probe rod of the probe mechanism is stuck, go to step 9.

[0024] Step 9: Operate the locking rod mechanism of the penetration platform to lock the rod. When the locking rod mechanism moves, it will press the feeler rod to fix the feeler rod and the penetration platform together. Then control the jack assisted by the jack auxiliary system, open the jack, push the jack and the penetration platform upward, and the penetration platform is connected to the feeler rod. At this time, the feeler rod is driven upward to pull the drill bit out of the feeler detection test point.

[0025] Step 10: Pull out the probe mechanism with the motor system from the penetration platform, and then disassemble the jack auxiliary support system to complete the entire probe test.

[0028] 2. The motor control system of the utility model turns on the controller through a switch, and the controller controls the micro motor, which in turn drives the winding mechanism to wind up the connecting rope, thereby realizing the automatic lifting of the vertical gravity hammer. The operation is simple and convenient, and the use effect is good. The motor of the winding mechanism drives the transmission wheel A to rotate, and the transmission wheel A drives the transmission wheel B to rotate through the belt, and the rotating wheel B drives the pulley and the rotating column to rotate, so as to pull up the connecting rope and realize the winding operation of the winding mechanism. The transmission structure is simple and the subsequent maintenance is convenient.

[0052] The following is the derivation process of the linear regression formula used in step 7:

[0053] At present, the relevant specifications of the geotechnical engineering industry do not have a specific number of N for light dynamic penetration. 10 and the bearing capacity characteristic value f ak (kPa) whether it meets certain correlations. Among them, the local specifications related to the Technical Specifications for Building Foundation Testing (JGJ340-2015) and the Railway Engineering Geological In-situ Testing Regulations (TB10018-2018) provide a light dynamic penetration test N 10The data for determining the characteristic value of foundation bearing capacity is obtained through summarizing geotechnical engineering investigation and test data of a large number of engineering cases accumulated in various regions of the industry. The accuracy is low, so it is necessary to optimize the calculation to improve the accuracy of the data.

[0054] The number of hits N for the light dynamic penetration test specified in the Technical Specifications for Building Foundation Testing (JGJ340-2015) 10 Estimated characteristic value of foundation bearing capacity f ak (kPa) specific data see Table 1:

[0071] Embodiment 2: The difference from Embodiment 1 is that a pair of buckles 221 are symmetrically arranged at the top of the through-hole gravity hammer 22 along the center; there are two connecting ropes 41, the bottom of each connecting rope 41 is connected to the buckle 221, and the top is connected to the motor control system 4. When in use, the motor control system 4 drives the connecting ropes 41 on both sides to move upward at the same time, and drives the through-hole gravity hammer 22 to perform dynamic probing through the connecting ropes 41; the symmetrically arranged connecting ropes 41 cooperate with the buckles 221 of the through-hole gravity hammer 22, and can steadily pull up the through-hole gravity hammer 22, so that the through-hole gravity hammer 22 exerts uniform force when it falls and hits the gasket 23, and can steadily and reliably push the probing rod 21 into the probing test point.

[0072] The motor control system 4 also includes an installation box 42, a pair of winding mechanisms 43, a controller 44, and a micro motor 45 and a switch 46 electrically connected to the controller 44, wherein there are two micro motors 45; the installation box 42 is fixedly installed on the top surface of the probe rod 21, and a pair of winding mechanisms 43 are evenly installed on the side of the installation box 42, and a controller 44, two micro motors 45, a switch 46 and a counter 3 are installed inside, wherein the rotating shaft of the micro motor 45 passes through the installation box 42 and is connected to the winding mechanism 43; the switch 46 at one end passes through the side of the installation box 42 and is connected to the outside; the counter 3 is provided with a display screen, the counter 3 is respectively connected to the two micro motors 45, and the display screen of the counter 3 passes through the top surface of the installation box 42 and is connected to the outside; the connecting rope 41 passes through the installation box 42 and is connected to the motor winding mechanism 43. When in use, press the switch 46 on the installation box 42, and then turn on the controller 44. The controller 44 controls the two micromotors 45 to rotate simultaneously, thereby indirectly driving the core-penetrating gravity hammer 22 to complete multiple probes. During the operation of the motor winding mechanism 43, the counter 3 counts; wherein the controller 44 turns on the micromotor 45, and the micromotor 45 drives the winding mechanism 43 to move, and then drives the connecting rope 41 and the core-penetrating gravity hammer 22 to move upward through the winding mechanism 43. When the core-penetrating gravity hammer 22 moves to the top of the probe rod 21, the controller 44 turns off the motor. At this time, the core-penetrating gravity hammer 22 is acted upon by gravity and moves rapidly downward with the connecting rope 41, and then completes a single dynamic probe by striking the gasket 23 on the probe rod 21. Repeating this process can complete the entire dynamic probe operation; the control of the motor control system 4 is achieved through the switch 46, which can facilitate the operation and use of the dynamic probe device.

[0073] There are three support rods 12, which are evenly distributed on the bottom surface of the through-core platform 11, and the angle between every two support rods 12 is 120°. The jack auxiliary support system 1 formed by the combination of the three support rods 12 and the through-core platform 11 has good support effect and is stable and reliable to use.

[0074] A level meter 6 is installed on the side of the through-core platform 11. The level meter 6 can be leveled on the through-core platform 11 of the jack-assisted support system 1, which is convenient for the early installation of the device.

[0075] Example 3: The difference from Example 2 lies in that the winding mechanism 43 comprises a mounting seat 431, a transmission wheel A432, a transmission wheel and a conveyor belt 434, wherein the transmission wheel A432 is fixedly mounted on the rotating shaft of the micro motor 45; the bottom of the mounting seat 431 is fixedly mounted on the top surface of the mounting box 42, and a rotating column 435 is rotatably mounted on the other end; the rotating column 435 is fixedly connected to a pulley 436, and the end is also fixedly connected to the transmission wheel B433; the pulley 436 is fixedly connected to one end of the connecting rope 41; the conveyor belt 434 is respectively connected to the transmission wheel A432 and the transmission wheel B433. When the micro motor 45 rotates, it drives the transmission wheel A432 to rotate. When the rotating wheel A rotates, it drives the conveyor belt 434 to move. The movement of the conveyor belt 434 can drive the transmission wheel B433 to rotate. Since the transmission wheel B433 is fixedly connected to the rotating column 435, it will drive the rotating column 435 and the pulley 436 on the rotating column 435 to rotate. Then, the connecting rope 41 can be pulled up by rotating the pulley 436, and the connecting rope 41 can pull up the through-core gravity hammer 22. Then, when the micro motor 45 stops rotating, the through-core gravity hammer 22 will quickly drop under the action of gravity. The transmission structure of the winding mechanism 43 is simple, which is convenient for use and subsequent maintenance.

[0076] The locking rod mechanism 5 is composed of a three-jaw chuck 51 and an adjustment handle 52, wherein the handle is fixedly connected to the adjustment screw provided inside the three-jaw chuck 51; the bottom of the three-jaw chuck 51 is fixed to the top of the through-hole platform 11, and the through hole of the three-jaw chuck 51 corresponds to the through hole position of the through-hole platform 11.
