Description

Technical Field

[0001] This utility model relates to the field of penetrometer bracket technology, specifically a lightweight multi-functional penetrometer bracket. Background Technology

[0002] Lightweight cone dynamic penetration test involves driving a cone probe of a certain specification into the soil, determining the soil layer type based on the depth reached by the number of penetration blows, identifying the engineering properties of the soil, and making a comprehensive evaluation of the foundation soil.

[0003] In the current process of light-duty cone penetration testing, when encountering uneven terrain, it is impossible to stably control the angle of the probe entering the soil, which in turn cannot guarantee that the anchor rod enters vertically, easily affecting the accuracy of the test results. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a lightweight multi-functional penetrometer frame to solve the problems involved in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight multi-functional frame for a penetrometer, comprising a triangular support, a protective sleeve disposed at the center of the triangular support, a penetrometer rod disposed inside the protective sleeve, and a hammering mechanism disposed at the upper end of the triangular support;

[0006] The hammering mechanism includes a ring plate fixed to the outer periphery of the probe rod, and a heavy hammer located at the upper end of the ring plate. The heavy hammer has a through hole at its central axis and is sleeved on the outer periphery of the probe rod through the through hole.

[0007] Furthermore, the triangular bracket includes a ring rod, three support rods located at the lower end of the ring rod, and a fixing rod between each adjacent support rod.

[0008] Furthermore, the protective sleeve is fixedly connected to the lower end face of the annular rod.

[0009] Furthermore, the support rod includes a screw rod and threaded sleeves fitted at both ends of the screw rod, wherein the threads at both ends of the screw rod are in opposite directions.

[0010] Furthermore, the casing is equipped with a level for detecting the verticality of the casing.

[0011] Furthermore, the hammer has handles on both sides.

[0012] Furthermore, the lower end of the ring plate is provided with an annular clamp, and the end of the annular clamp is provided with a fastening bolt. The ring plate and the probe rod are fixedly connected by the fastening bolt and the annular clamp.

[0013] Furthermore, the diameter of the ring plate is larger than the diameter of the through hole on the counterweight.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features a casing that controls the angle at which the probe enters the soil, ensuring vertical insertion. The triangular support ensures the stability of the insertion, increasing the accuracy of the test. The weight can be used to strike the anchor rod into the soil, increasing ease of use and improving work efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Depend on Figure 1 As shown, a lightweight penetrometer multi-functional frame includes a triangular support and a protective sleeve 1 located at the center of the triangular support. A penetrometer rod 2 is installed inside the protective sleeve 1. The protective sleeve 1 is vertically positioned, and its guidance ensures that the penetrometer rod 2 is inserted vertically into the soil. A hammering mechanism is provided at the upper end of the triangular support; the lower end of the penetrometer rod 2 contacts the ground, and the hammering mechanism can drive the penetrometer rod 2 into the soil.

[0023] The hammering mechanism includes a ring plate 3 fixed to the outer periphery of the probe rod 2, and a hammer 4 positioned above the ring plate 3. The hammer 4 has a through hole at its central axis, through which it is fitted onto the outer periphery of the probe rod 2. Handles 5 are provided on both sides of the hammer 4. The diameter of the ring plate 3 is larger than the diameter of the through hole on the hammer 4. A ring-shaped clamp is provided at the lower end of the ring plate 3, and a fastening bolt is provided at the end of the clamp. The ring plate 3 and the probe rod 2 are fixedly connected by the fastening bolt and the ring clamp. After fixing the ring plate 3 to the probe rod 2, the hammer 4 is fitted onto the probe rod 2 and contacts the upper surface of the ring plate 3. During hammering, the hammer 4 is lifted, falls naturally, and strikes the ring plate 3, thereby driving the probe rod 2 into the soil.

[0024] The triangular bracket includes a ring rod 6 and three support rods 7 located at the lower end of the ring rod 6, with a fixing rod 8 between each adjacent support rod 7. The protective sleeve 1 is fixedly connected to the lower end face of the ring rod 6. The triangular bracket increases stability.

[0025] Example 2:

[0026] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows:

[0027] The support rod 7 includes a screw 71 and threaded sleeves 72 fitted at both ends of the screw 71, with the threads at both ends of the screw 71 in opposite directions. A fixing rod 8 is located between adjacent threaded sleeves 72 on the upper side. A level 9 is provided on the protective sleeve 1 to detect the verticality of the protective sleeve 1. When the terrain is uneven, the screw 71 is rotated to adjust the length of the support rod 7 until the level 9 on the protective sleeve 1 shows that the protective sleeve 1 is in a vertical direction, increasing the accuracy of the detection.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
