Technical Field

[0001] The utility model relates to the field of geological survey machinery, in particular to a portable light-duty dynamic probe machine. Background Art

[0002] The penetration tester is a field or construction site testing equipment used for geological surveys, mainly used to determine the bearing capacity of the foundation. It uses a certain mechanical transmission method to vertically press a probe of a certain specification into the soil layer, and uses the penetration resistance measured by the measurement system to determine the properties of the soil layer and stratify the soil layer. The equipment is suitable for coarse and medium sand, fine sand, silt sand, clay and soil layers containing a small amount of gravel. It has the advantages of being light, flexible, fast, accurate, easy to operate, safe and reliable.

In addition, the height of the hammer varies with the height and standing posture of the operator, resulting in different hammer heights and large variations in drop distances. The drop distance is not constant, which causes large fluctuations in hammer energy and has a significant impact on the in-situ test results. Utility Model Content

[0035] Combine the following Figures 1 to 6 The portable light dynamic probe machine 10 provided in this embodiment is described in detail.

[0036] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The embodiment of the utility model provides a portable light dynamic probe machine 10, including a bracket 100, a pad 200, a drop hammer 300, a slide rail 400, a rotating arm 500 and a power mechanism 600.

[0037] It should be noted that the dynamic probe is divided into three types: light, heavy and extra heavy. The weight of the light dynamic probe is 10kg, the weight of the heavy dynamic probe is 63.5kg, and the weight of the extra heavy dynamic probe is 120kg. The "light" in the portable light dynamic probe machine 10 provided in this embodiment refers to the light dynamic probe.

[0038] The pad 200, the drop hammer 300, the slide rail 400, the rotating arm 500 and the power mechanism 600 are all arranged on the bracket 100. During construction, the sounding rod is vertically fixed to the bottom of the pad 200. During the rotation of the rotating arm 500 around one end, Figure 6 The motion trajectory of the other end of the rotating arm 500 is circular and slides with the slide rail 400, thereby pushing the slide rail 400 and the drop hammer 300 to move upward synchronously until the rotating arm 500 slides out of the slide rail 400, and the slide rail 400 is separated from the support of the rotating arm 500. The slide rail 400 and the drop hammer 300 move downward under the action of gravity, hit the pad 200, and push the entire bracket 100 and the components provided on the bracket 100 to move downward synchronously, thereby pushing the sounding rod downward into the soil layer, the rotating arm 500 rotates reciprocatingly, and the drop hammer 300 also hammers reciprocatingly to hit the pad 200, so that the sounding rod is pressed vertically into the soil layer step by step.

[0039] The power mechanism 600 is used to drive the rotating arm 500 to rotate continuously to realize the upward and downward movement of the drop hammer 300 in the vertical direction, which greatly reduces the labor intensity during operation and solves the problem of continuous testing operation; in addition, the length of the rotating arm 500 is fixed, the length of the slide rail 400 is fixed, and the movement trajectories of the rotating arm 500 and the slide rail 400 are fixed. The height of the hammer during the rotation of the rotating arm 500 is constant, the drop distance is also constant, and each hammering energy is constant. There is no fluctuation deviation on the test results. The test data is accurate and the results are reliable. The problem of different manual hammer lifting heights and large changes in drop distances, which have a great impact on the in-situ test results, is solved.

[0040] Reference Figure 1 In this embodiment, the power mechanism 600 includes a motor 610 and a reduction mechanism; the motor 610 and the reduction mechanism are used to drive the rotating arm 500 to rotate in a vertical plane. The motor 610 and the reduction mechanism are used to drive the rotating arm 500, which has a simple structure and is easy to operate. The rotating arm 500 rotates in a vertical plane and can provide the maximum lifting force to the drop hammer 300.

[0041] Reference Figure 1 In this embodiment, the motor 610 is an adjustable speed motor. An adjustable speed motor is a motor that can change its speed. The speed can be adjusted by changing its supply voltage, frequency, current or number of magnetic poles, so as to achieve efficient use of the motor 610.

[0042] The change of the rotation speed of the motor 610 can change the rotation frequency of the rotating arm 500, change the frequency of the drop hammer 300 hitting the pad 200, and thus change the speed at which the probing rod is pressed downward into the soil layer, so that the probing machine can be suitable for testing different soil formations and solve the leading or lagging effects of formation sensitivity on the test data.

The drop hammer 300 is always coaxial with the hitting pad 200 during the up and down movement, ensuring that the drop hammer 300 can directly hit the hitting pad 200 after falling downward, thereby increasing the hammering force.

[0048] Reference Figure 1 , Figure 2 and Figure 4 In this embodiment, the bracket 100 further includes a secondary guide rod 130 ; the secondary guide rod 130 is vertically fixed on the bottom plate 110 , the slide rail 400 is horizontally fixed to the drop weight 300 , and the slide rail 400 is slidably matched with the secondary guide rod 130 .

[0054] According to a portable light power probe machine 10 provided in this embodiment, the working principle of the portable light power probe machine 10 is: the rotating arm 500 is driven by the motor 610 and the reduction mechanism to drive the sliding bearing 510 to reciprocate in the slide rail 400, thereby driving the drop hammer 300 to be lifted to a set height along the guide rod 120; when the sliding bearing 510 is separated from the slide rail 400, the drop hammer 300 falls freely and strikes the pad 200; continuous hammering causes the probe rod connected to the pad 200 to enter the tested formation at a uniform speed, thereby measuring the relevant physical and mechanical parameters of the formation.

[0055] The portable lightweight dynamic probe machine 10 provided in this embodiment has at least the following advantages:

[0056] The power mechanism 600 is used to drive the rotating arm 500 to lift the hammer, which greatly reduces the labor intensity during operation and solves the problem of continuous testing operation.
