Description
Technical Field
[0001] This utility model relates to the field of foundation pit detection technology, and in particular to a novel dynamic penetration test device. Background Technology
[0002] Currently, dynamic penetration tests are used in the construction of housing, road, municipal and water conservancy projects. The dynamic penetration test uses a certain amount of hammer energy to drive a probe and probe rod of a certain specification into the soil. The soil layer changes are judged based on the difficulty of penetration, i.e. the magnitude of soil resistance, and mechanical analysis is performed to evaluate the engineering properties of the soil. The number of hammer blows required to penetrate a certain distance in the soil is used to characterize the soil resistance. An empirical relationship is established between this and the physical and mechanical properties of the soil for use in engineering practice.
[0003] When the soil layer for dynamic penetration testing is relatively hard, a large number of dynamic penetration blows are required. This makes counting the blows cumbersome and prone to errors. During the test, the penetration rod is prone to swaying, especially in the lower, hard soil layers. This not only easily causes deformation and damage to the rod but also leads to discrepancies between the test results and the actual conditions, affecting the selection of design parameters and ultimately impacting the safety and stability of the superstructure. Existing dynamic penetration testing equipment starts from the bottom of the pit and records the number of blows from the surface. Because the test point is within the critical depth range, the measured number of blows is generally low, resulting in test results that do not meet the bearing capacity requirements provided by the survey and design. Traditional lightweight dynamic penetration testing equipment is manually operated, which has disadvantages such as high labor intensity, low testing accuracy, and difficulty in ensuring construction safety. In recent years, some hammering devices for lightweight dynamic penetration testing have emerged, but these devices still require manual support during the test, failing to further reduce labor intensity and improve construction safety. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a novel power penetration device, which aims to improve the problem of easy errors in counting the number of hammer blows in existing power penetration devices.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel power penetrometer, comprising a support frame, the support frame including a bracket frame, a top plate being provided at the top of the bracket frame, a first slide rail being provided at the center of the top plate, a pressure counter being provided on the lower surface of the top plate, diagonal braces being provided on all four sides of the bracket frame, a second slide rail being provided at the bottom of the bracket frame, multiple steel pipes being provided on the outside of the second slide rail, a vernier caliper being provided below the bracket frame, a red penetrometer rod being provided on the inner wall of the first slide rail, and a graduated penetrometer rod being provided at the bottom of the red penetrometer rod.
[0006] As a further description of the above technical solution: The top plate is equipped with a hammering device, which includes a frame, a transmission mechanism, a telescopic cylinder, a piston one, a rotary valve one, a rotary valve two, a piston two, a hammer rod, a hammer head, and an anvil. The anvil includes an anvil pad and a top plate. The anvil pad has a hole in the center that is the same size as the slide rail one. The anvil pad is directly connected to the top plate and fixed to the top plate with four screws. The transmission mechanism is connected to piston one. Piston two is located inside the cylinder, and piston one is located inside the telescopic cylinder. Rotary valve one and rotary valve two are respectively located at the connection position between the cylinder and the telescopic cylinder. One end of the hammer rod is connected to the hammer head, and the other end is connected to piston two, which is located directly above the anvil. The rotary valve is located between piston one and piston two and is set to open automatically after a certain period of time.
[0007] As a further description of the above technical solution: A running device controller is provided near the edge of the top surface of the top plate. The running device controller includes a sensor, a relay, a power supply, a rotary valve switch setter, and a pressure regulating valve. The sensor is located on a vernier caliper below the top plate and is connected to a relay located on the hammering device frame. The power supply, rotary valve switch setter, and pressure regulating valve are also located on the hammering device frame.
[0008] As a further description of the above technical solution: The upper part of the probe rod is marked with a scale, and the red probe rod is wrapped in red.
[0009] As a further description of the above technical solution: The pressure counter is used to record the number of hammer blows.
[0010] As a further description of the above technical solution: The slide rails one and two ensure the verticality of the probe rod is properly controlled, providing a deep track for the probe rod.
[0011] As a further description of the above technical solution: The transmission mechanism includes a reducer, crankshaft, and connecting rod system, and is used to generate compressed air.
[0012] As a further description of the above technical solution: The vernier caliper is equipped with a color-sensitive sensor on its outer wall, and the pressure regulating valve is used to control the simultaneous opening and closing of rotary valve one and rotary valve two.
[0013] This utility model has the following beneficial effects: 1. In this utility model, a multi-functional device replaces traditional manual operation, saving manpower during the test, improving construction safety, and ensuring the authenticity and accuracy of the foundation bearing capacity test results. The pressure counter can read the blow count data very intuitively, and the slide rail prevents the dynamic cone penetrometer from shaking, thus preventing the dynamic cone penetrometer from tilting. This effectively avoids the problem of inadequate verticality control of the cone penetrometer rod during the construction trench inspection, and avoids the defects of easy damage and deformation. It can be manually assembled, making the operation simple and cost-effective. The cone penetrometer rod can be quickly and easily disassembled and assembled, thereby improving testing efficiency.

[0019] Please see the appendix Figure 1The top surface of the top plate 202 is equipped with a running device controller 1 near the edge. The running device controller 1 includes a sensor, a relay, a power supply, a rotary valve switch setter, and a pressure regulating valve. The sensor is set on the vernier caliper 8 below the top plate 202 and is connected to the relay set on the frame of the hammering device 6. The power supply, the rotary valve switch setter, and the pressure regulating valve are also set on the frame of the hammering device 6. The scale setting probe 9 has a scale on its upper part. The red probe 3 is wrapped in red to facilitate the detection of the color sensor 7. Specifically, the operating device controller 1, located near the edge of the top surface of the top plate 202, ensures the efficient operation of the entire device. The operating device controller 1 includes sensors, relays, power supply, rotary valve switch setter, and pressure regulating valve. These components work together to achieve precise control and monitoring.

[0020] Please see the appendix Figure 1 The pressure counter 203 is used to record the number of hammer blows. The slide rail 1 4 and slide rail 2 5 control the verticality of the probe rod and provide a deep track for the probe rod. The transmission mechanism includes a reducer, crankshaft, and connecting rod system to generate compressed air. The vernier caliper 8 is equipped with a color sensor 7 on its outer wall. The pressure regulating valve is used to control the simultaneous opening and closing of rotary valve 1 and rotary valve 2. Specifically, the main function of the pressure counter 203 is to record the number of hammer blows. Slide rails 4 and 5 ensure precise control of the verticality of the probe rod, providing a deep track for its smooth up-and-down movement and ensuring measurement accuracy. The transmission mechanism, including a reducer, crankshaft, and connecting rod, effectively generates compressed air to provide power for the entire device. A color-sensitive sensor 7 is installed on the outer wall of the vernier caliper 8, enabling more accurate readings of the measurement results. The function of the pressure regulating valve is to control the synchronous opening and closing of rotary valve one and rotary valve two, ensuring the stability and safety of gas flow. Before operation, the color sensor 7 is set on a preset scale. When the color sensor 7 receives a red signal from the red probe 3, the color sensor 7 outputs a switch signal to control the relay coil to de-energize, thereby de-energizing the hammering device 6 and stopping its operation. When the sensor receives a non-red signal from the probe, the color sensor 7 outputs a switch signal to control the relay coil to energize, thereby allowing the hammering device 6 to continue operating.
[0021] Working principle: When using the device, first set the opening time of the rotary valve of the operating device controller 1, the pressure value on the pressure regulating valve, and the height of the color sensor 7. Then turn on the power, and the motor starts to operate. The motor drives the piston of the telescopic cylinder to move up and down through the transmission mechanism, generating compressed air. The compressed air then enters the cylinder through the rotary valve, pushing the piston to move up and down, thereby driving the hammer rod and hammer head to move. The thrust is then transmitted through the hammer head to the red probe rod 3 and the scale setting probe rod 9. When the scale setting probe rod 9 reaches or slightly exceeds the preset height of the color sensor 7, the color sensor 7 outputs a switch signal to control the relay to cut off the power, thereby stopping the hammering device 6 from operating.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
