Description

Technical Field

[0001] This utility model relates to a lightweight dynamic penetrometer. It is applicable to the field of penetrometer testing. Background Technology

[0002] Lightweight dynamic cone penetration test (DPT), also known as dynamic cone penetration test, uses a heavy hammer to drive a standard-sized probe connected to a probe rod into the soil. The mechanical properties of the soil are determined by the number of blows required to penetrate 10cm or 30cm (where N10 counts every 30cm, and N63.5 and N120 count every 10cm). However, current dynamic cone penetration tests have the following drawbacks:

[0003] Currently, in light dynamic penetration tests, two workers typically operate the system. One worker holds the top of the guide rod for an extended period to ensure the stability of the testing device, while the other continuously raises and lowers the hammer. Holding the guide rod for extended periods is not only tiring for the workers but also wastes manpower. Furthermore, in practice, due to human factors, the counting of hammer raises and the drop distance may be inaccurate when the workers are fatigued, affecting the test results and leading to significant deviations. Therefore, a device to accelerate light dynamic penetration tests is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is: to solve the above-mentioned technical problem, this utility model provides a lightweight dynamic penetration test device.

[0005] The technical solution adopted in this utility model is: a lightweight dynamic penetration test device, which has the following features:

[0006] The base has two vertically arranged columns installed on it, and each column has a sliding groove along its length.

[0007] The connecting plate is connected to two columns at both ends, and sliders that can slide and engage with the sliding grooves on the columns on both sides of the connecting plate are installed at both ends of the connecting plate.

[0008] The probe assembly is installed vertically below the connecting plate. A probe is installed at the lower end of the probe assembly. A hammer seat is fixedly installed on the side wall of the probe. A hammer body that can slide along the length of the probe assembly is mounted on the probe assembly above the hammer seat. A striking plate arranged horizontally is installed on the hammer body.

[0009] The drive mechanism is mounted on the connecting plate. When the drive mechanism runs to contact the striking plate, it can drive the striking plate and the hammer to move upward. When the drive mechanism runs to cancel contact with the striking plate, the hammer and the striking plate fall under their own weight and strike the hammer base.

[0010] The drive mechanism has a mounting plate fixedly installed below the connecting plate. A motor is mounted on the mounting plate, and the output shaft of the motor is arranged in a horizontal direction. A striking rod arranged in a radial direction along the output shaft is fixedly installed on the output shaft of the motor. When the striking rod rotates upward, it can contact the striking plate. When the striking rod starts to rotate downward, it cancels the contact with the striking plate.

[0011] An installation groove is formed on the striking rod along the length of the striking rod. An adjusting rod that can move along the length of the striking rod is installed in the installation groove. A first positioning hole is formed on the side wall of the adjusting rod. At least two second positioning holes are formed on the striking rod at positions corresponding to the first positioning holes along the length of the striking rod. A bolt that can pass through the second positioning holes and is threaded into the first positioning holes is installed on the striking rod.

[0012] A roller is installed at the end of the adjusting rod that extends beyond the striking rod.

[0013] Handles are installed on the side walls of the two columns.

[0014] The probe assembly has a probe and a guide rod. The guide rod is installed at the lower end of the connecting plate, and the probe is installed at the lower end of the guide rod by a threaded connection. The hammer seat is fixedly installed on the guide rod, and the hammer body is slidably installed on the guide rod.

[0015] Support rods are installed on the same side wall of both columns, and casters are installed at the ends of the support rods.

[0016] A handle is provided on the connecting plate.

[0017] The beneficial effects of this utility model are as follows: This utility model sets two columns on the base, connects the two columns with a connecting plate, installs a probe assembly below the connecting plate, fixes a hammer seat on the probe assembly, and installs a slidable hammer body on the probe assembly above the hammer seat. This facilitates the upward movement of the hammer body, allowing it to fall under its own weight and strike the hammer seat after being released. The sliding blocks at both ends of the connecting plate, in conjunction with the sliding grooves on the columns, drive the probe assembly downwards. Furthermore, this utility model installs a striking plate on the hammer body, and sets a mounting plate and motor below the connecting plate, facilitating the rotation of the striking rod when the motor is running. During the upward rotation of the striking rod, the striking plates come into contact with each other, thereby driving the striking plates and hammer body to move upward under the sliding fit between the hammer body and the probe assembly. When the striking rod begins to rotate downward, the striking plates lose contact with each other, and the hammer body and striking plates fall under their own weight, facilitating the automatic operation of the light dynamic penetration test. The hammering is more even during the test, and it is also easier to judge the number of blows based on the motor's operation. This utility model also facilitates the replacement of the probe rod when it wears due to prolonged use by threading the probe rod onto the guide rod and mounting the hammer seat and hammer body onto the guide rod.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0026] Example 1 is a lightweight dynamic penetration test device, which has the following features:

[0027] The base 1 has two vertically arranged columns 2 installed on it, and each column 2 has a sliding groove 2-1 arranged along the length of the column 2.

[0028] The connecting plate 3 is connected to two columns 2 at both ends. The connecting plate 3 is equipped with sliders 3-1 at both ends that can slide and engage with the sliding grooves 2-1 on the columns 2 on both sides of the connecting plate 3.

[0029] The probe assembly 4 is installed vertically below the connecting plate 3. The probe 4-1 is installed at the lower end of the probe assembly 4. The hammer seat 4-2 is fixedly installed on the side wall of the probe 4-5. The hammer body 4-3, which can slide along the length of the probe assembly 4, is fitted on the probe assembly 4 above the hammer seat 4-2. The hammer body 4-3 is installed with a horizontally arranged striking plate 4-4, which is installed on the hammer body 4-3 through a connecting rod.

[0030] The drive mechanism 5 is installed on the connecting plate 3. When the drive mechanism 5 runs to contact the striking plate 4-4, it can drive the striking plate 4-4 and the hammer 4-3 to move upward. When the drive mechanism 5 runs to cancel contact with the striking plate 4-4, the hammer 4-3 and the striking plate 4-4 fall under their own weight and strike the hammer base 4-2. Thus, after the base 1 is placed on the ground, the probe 4-1 at the bottom of the probe assembly 4 contacts the ground under the sliding cooperation of the sliders 3-1 at both ends of the connecting plate 3 and the sliding grooves 2-1 on the two side columns 2. When the drive mechanism 5 is running, it can drive the striking plate 4-4 and the hammer 4-3 to move upward. After the drive mechanism 5 drives the striking plate 4-4 to the top, the cooperation with the striking plate 4-4 is canceled. At this time, the striking plate 4-4 and the hammer 4-3 fall under their own weight and strike the hammer seat 4-2, thereby hammering the probe assembly 4 into the ground. Since the drive mechanism 5 and the probe assembly 4 are both installed on the connecting plate 3, the drive mechanism 5 also moves downward with the probe assembly 4, so that the drive mechanism 5 can still cooperate with the striking plate 4-4 after the probe assembly 4 falls.

[0031] Example 2 is a lightweight dynamic penetration test device. Based on Example 1, in this example, the drive mechanism 5 has a mounting plate 5-1 fixedly installed below the connecting plate 3. A motor 5-2 is installed on the mounting plate 5-1. The output shaft of the motor 5-2 is arranged in the horizontal direction. A striking rod 5-3 arranged in the radial direction of the output shaft is fixedly installed on the output shaft of the motor 5-2. When the striking rod 5-3 rotates upward, it can contact the striking plate 4-4. When the striking rod 5-3 starts to rotate downward, it cancels the contact with the striking plate 4-4. Thus, when the motor 5-2 is running, it can drive the striking rod 5-3 to rotate. When the striking rod 5-3 rotates upward, it can contact the striking plate 4-4 and drive the striking plate 4-4 and the hammer body 4-3 to move upward. When the striking rod 5-3 begins to move downward, the striking rod 5-3 cancels contact with the striking plate 4-4. At this time, the striking plate 4-4 and the hammer body 4-3 are only subjected to gravity and fall. The impact of the hammer body 4-3 on the hammer base 4-2 causes the probe rod assembly 4 to move downward.

[0032] In this embodiment, a mounting groove is formed on the striking rod 5-3 along its length. An adjusting rod 5-4, movable along the length of the striking rod 5-3, is installed in the mounting groove. A first positioning hole 5-5 is formed on the side wall of the adjusting rod 5-4. At least two second positioning holes 5-6 are formed on the striking rod 5-3 at positions corresponding to the first positioning holes 5-5 along its length. A bolt 5-7, capable of passing through the second positioning holes 5-6 and threadedly engaging with the first positioning holes 5-5, is installed on the striking rod 5-3. This allows for adjustment of the length of the adjusting rod 5-4 by fixing it at different positions on the striking rod 5-3, thereby adjusting the rising height of the hammer body 4-3.

[0033] In this embodiment, a roller 5-8 is installed at the end of the adjusting rod 5-4 that extends beyond the striking rod 5-3. Thus, when the striking rod 5-3 and the adjusting rod 5-4 rotate to the contact position with the striking plate 4-4, the roller 5-8 effectively reduces wear between the adjusting plate and the striking plate 4-4.

[0034] Example 3 is a lightweight dynamic penetration test device. Based on Example 1, this example includes handles 6 installed on the side walls of the two columns 2. This facilitates personnel in grasping the lightweight dynamic penetration test device and adjusting its position.

[0035] Example 4 is a lightweight dynamic penetrometer. Based on Example 1, in this example, the probe assembly 4 includes a probe 4-5 and a guide rod 4-6. The guide rod 4-6 is mounted on the lower end of the connecting plate 3, and the probe 4-5 is threaded onto the lower end of the guide rod 4-6. The hammer seat 4-2 is fixedly mounted on the guide rod 4-6, and the hammer body 4-3 is slidably mounted on the guide rod 4-6. This allows for easy replacement of the probe 4-5 by loosening it from the guide rod 4-6 when it wears out due to prolonged use.

[0036] Example 5 is a lightweight dynamic penetration test device. Based on Example 1, in this example, support rods 7 are installed on the same side wall of both columns 2, and movable wheels 8 are installed at the ends of the support rods 7. A handle 9 is provided on the connecting plate 3. In this way, by tilting the lightweight dynamic penetration test device, the movable wheels 8 are made to contact the ground while the base 1 is not in contact with the ground, making it easy for personnel to move the lightweight dynamic penetration test device on the ground by holding the handle 9.

[0037] Example 6 is a lightweight dynamic penetration test device, which has the following features:

[0038] The base 1 has two vertically arranged columns 2 installed on it, and each column 2 has a sliding groove 2-1 arranged along the length of the column 2.

[0039] The connecting plate 3 is connected to two columns 2 at both ends. The connecting plate 3 is equipped with sliders 3-1 at both ends that can slide and engage with the sliding grooves 2-1 on the columns 2 on both sides of the connecting plate 3.

[0040] The probe assembly 4 is installed vertically below the connecting plate 3. The probe 4-1 is installed at the lower end of the probe assembly 4. The hammer seat 4-2 is fixedly installed on the side wall of the probe 4-5. The hammer body 4-3, which can slide along the length of the probe assembly 4, is mounted on the probe assembly 4 above the hammer seat 4-2. The hammer body 4-3 is equipped with a striking plate 4-4 arranged horizontally.

[0041] The drive mechanism 5 is installed on the connecting plate 3. When the drive mechanism 5 runs to contact the striking plate 4-4, it can drive the striking plate 4-4 and the hammer 4-3 to move upward. When the drive mechanism 5 runs to cancel contact with the striking plate 4-4, the hammer 4-3 and the striking plate 4-4 fall under their own weight and strike the hammer base 4-2.

[0042] The drive mechanism 5 has a mounting plate 5-1 fixedly installed below the connecting plate 3. A motor 5-2 is mounted on the mounting plate 5-1. The output shaft of the motor 5-2 is arranged in the horizontal direction. A striking rod 5-3 arranged in the radial direction of the output shaft is fixedly installed on the output shaft of the motor 5-2. When the striking rod 5-3 rotates upward, it can contact the striking plate 4-4. When the striking rod 5-3 starts to rotate downward, it cancels the contact with the striking plate 4-4.

[0043] An installation groove is formed on the striking rod 5-3 along the length direction of the striking rod 5-3. An adjusting rod 5-4 that can move along the length direction of the striking rod 5-3 is installed in the installation groove. A first positioning hole 5-5 is formed on the side wall of the adjusting rod 5-4. At least two second positioning holes 5-6 are formed on the striking rod 5-3 at positions corresponding to the first positioning holes 5-5 along the length direction of the striking rod 5-3. A bolt 5-7 that can pass through the second positioning holes 5-6 and is threadedly engaged with the first positioning holes 5-5 is installed on the striking rod 5-3.

[0044] A roller 5-8 is installed at the end of the adjusting rod 5-4 that extends beyond the striking rod 5-3.

[0045] Handles 6 are installed on the side walls of the two columns 2.

[0046] The probe assembly 4 has a probe 4-5 and a guide rod 4-6. The guide rod 4-6 is installed at the lower end of the connecting plate 3, and the probe 4-5 is installed at the lower end of the guide rod 4-6 by threaded connection. The hammer seat 4-2 is fixedly installed on the guide rod 4-6, and the hammer body 4-3 is slidably installed on the guide rod 4-6.

[0047] Support rods 7 are installed on the same side wall of both columns 2, and movable wheels 8 are installed at the ends of the support rods 7.

[0048] A handle 9 is made on the connecting plate 3.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
