Description

Technical Field

[0001] The utility model belongs to the technical field of supporting tooling for dynamic penetration instruments, and particularly relates to a simple rod pulling tool for dynamic penetration. Background Art

[0002] Dynamic penetration testing is an in-situ testing method that uses a certain amount of drop hammer energy to drive a probe of a certain specification together with a probe rod into the soil, and determines the engineering properties of the soil based on the difficulty of penetration (usually expressed as penetration rate, number of hammer blows or dynamic penetration resistance per unit area of ​​the probe). Dynamic penetration testing has a wide range of applicability, and is suitable for strongly weathered and fully weathered hard rocks, various soft rocks and various types of soil.

[0003] However, when the probe penetrates deep into the soil during testing, it will be difficult to pull out the probe. Traditional probes are usually pulled out manually or using the reverse force of a heavy hammer, which is time-consuming, labor-intensive and has low work efficiency. Summary of the invention

[0004] In order to solve the above problems, the utility model aims to provide a simple rod pulling tool for power probing.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a simple rod pulling tool for power probing, which includes a power rod, a resistance rod, a fulcrum rotating shaft, a bracket, a bearing plate, a rod puller and a rod puller rotating shaft; wherein the bearing plate is horizontally placed on the ground; the lower end of the bracket is fixed on the bearing plate; one end of the resistance rod is connected to the rear end of the rod puller through the rod puller rotating shaft, the middle part is connected to the upper end of the bracket through the fulcrum rotating shaft, and the other end is connected to one end of the power rod; the front part of the rod puller is stuck on the outside of the power probing rod.

[0006] The power rod and the resistance rod are connected by threads to form a long lever, which can be disassembled after use to save space.

[0007] The front part of the rod puller is a concave plate, and the width of the notch is greater than the diameter of the power feeler rod, and the power feeler rod is clamped by the notch.

[0008] The simple rod pulling tool for dynamic probing provided by the utility model has the following beneficial effects: it is easy to use, easy to carry, can effectively improve the speed of dynamic probing test, is flexible and simple to operate, improves work efficiency, saves manpower and has high safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 A schematic diagram of a simple rod pulling tool for dynamic probing provided by the utility model. DETAILED DESCRIPTION

[0010] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1 As shown, the simple rod pulling tool for power sounding provided by the utility model includes a power rod 1, a resistance rod 2, a fulcrum rotating shaft 3, a bracket 4, a bearing plate 5, a rod puller 6 and a rod puller rotating shaft 8; wherein the bearing plate 5 is horizontally placed on the ground; the lower end of the bracket 4 is fixed on the bearing plate 5; one end of the resistance rod 2 is connected to the rear end of the rod puller 6 through the rod puller rotating shaft 8, the middle part is connected to the upper end of the bracket 4 through the fulcrum rotating shaft 3, and the other end is connected to one end of the power rod 1; the front part of the rod puller 6 is stuck on the outside of the power sounding rod 7.

[0012] The power rod 1 and the resistance rod 2 are connected by threads to form a long lever, which can be disassembled after use to save space.

[0013] The front part of the rod puller 6 is a concave plate, and the width of the notch is greater than the diameter of the dynamic feeler rod 7, and the dynamic feeler rod 7 is clamped by the notch.

[0014] The method of using the simple rod pulling tool for dynamic probing provided by the utility model is described as follows:

[0015] When it is necessary to use this rod pulling tool to pull out the power sounding rod 7, the staff first connects the power rod 1 and the resistance rod 2 through a thread to form a long lever, and assembles the middle part of the resistance rod 2 into a lever through the fulcrum rotating shaft 3 and the bracket 4. Then, the rod puller 6 is lowered and the power sounding rod 7 is clamped by the notch. After that, a downward force is applied on the side of the power rod 1, and the power sounding rod 7 can be easily pulled out. After use, the components on the rod pulling tool are disassembled for easy carrying.
