Description

Technical Field

[0001] This utility model relates to a hole forming device for a nuclear density meter of roller-compacted concrete. Background Technology

[0002] In the construction of large-scale projects such as water conservancy and hydropower, there are numerous concrete construction scenarios, among which roller-compacted concrete (RCC) is a highly efficient and economical construction method. During RCC construction, testing personnel need to use a nuclear density meter to test the density of the compacted RCC according to specifications. Traditionally, density testing involves manually using a 4-pound hammer to strike a test rod to create a test hole in the RCC. This operation is time-consuming, labor-intensive, inefficient, cannot sustain high-intensity testing, and cannot effectively control the depth of the test hole. Utility Model Content

[0003] The technical problem to be solved by this utility model is that, in order to address the shortcomings of the time-consuming, labor-intensive, and inefficient manual hole-making operation when using a nuclear density meter to test the compaction of roller-compacted concrete, this utility model provides a hole-forming device for a nuclear density meter of roller-compacted concrete that can effectively improve the efficiency of manual operation and effectively control the depth of the test hole.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A rolling concrete nuclear density meter hole forming device includes a drill rod for hole making and an electric hammer. The power output end of the electric hammer is equipped with a drill rod clamping system, which is connected to the drill rod via a quick-release connector. The lower end of the drill rod has an elliptical hammer head, and the electric hammer is also equipped with an infrared rangefinder for automatically measuring the hole depth.

[0006] In this way, this invention uses an electric hammer to drive the chisel rod to rotate, thereby achieving the forming of test holes in roller-compacted concrete. Because this invention uses an electric hammer to provide power for the hole-making operation, it not only greatly reduces the workload but also significantly improves the efficiency of the hole-making process. During the hole-making process, the depth of the test hole can be effectively controlled in real time using an infrared rangefinder.

[0007] Preferably, the infrared rangefinder is a miniature digital display infrared rangefinder.

[0008] Preferably, the upper end of the drill rod has a quick-release interface that matches the quick-release connector.

[0009] Preferably, the electric hammer is equipped with a battery for powering the hammer. The electric hammer used in this invention is a commercially available product that can be powered by mains electricity and is also equipped with a battery for convenient field operations.

[0010] Preferably, the battery is a rechargeable battery.

[0011] Preferably, the rechargeable battery is a lithium battery or a lead-acid battery.

[0012] Preferably, the drill rod is marked with a scale for measuring the hole depth and comparing it with the automatically measured hole depth to ensure the hole accuracy.

[0013] This invention combines a rechargeable electric hammer, a drill rod clamping system, and a drill rod. Operators only need to control the power switch of the electric hammer to complete the nuclear density meter hole forming work. The drilling depth can also be displayed in real time through an infrared rangefinder. This not only greatly improves work efficiency and accurately controls the hole depth, but also causes less disturbance to the compacted concrete during the operation process, and the hole verticality is high, which can more realistically represent the density of the concrete.

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

[0015] 1) This utility model has the advantages of simple structure, easy operation, economy and strong practicality. It effectively solves the technical problems of low manual efficiency and inaccurate control of hole depth in traditional hole measuring and drilling operations. At the same time, it also reduces personal safety problems caused by the decline in physical strength of the testing personnel.

[0016] 2) This utility model is particularly suitable for construction scenarios with high frequency and high intensity. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1 , Figure 2 An embodiment of the rolling concrete nuclear density meter hole forming device of this utility model includes an electric hammer 1, a battery 2, a chisel 3, a chisel clamping system 4, and an infrared rangefinder 5.

The drill rod 3 is a solid iron rod with a quick-release interface at its upper end that matches the quick-release connector 41, and an elliptical hammer head 31 at its lower end. A scale (not shown in the figure) is marked on the drill rod for measuring the hole depth. Comparing the hole depth measured by the scale with the hole depth automatically measured by the infrared rangefinder 5 ensures the accuracy of the drilling.

[0026] The electric hammer 1 is a commercially available product that can be powered by mains electricity and is equipped with the battery 2 for convenient field operations. The battery 2 is preferably a rechargeable battery such as a lithium battery or lead-acid battery.

[0027] This invention uses an electric hammer 1 to drive a drill rod 3 to jump up and down on a compacted concrete surface to form a hole. As the drill rod 3 drills in, an infrared rangefinder 5 displays the hole depth in real time.

[0028] The method of using this utility model is as follows: Select a flat and compacted concrete surface, turn on the miniature digital display infrared rangefinder 5, keep the drill rod 3 perpendicular to the compacted concrete surface, the operator holds the electric hammer 1 with one hand and firmly holds the power switch of the electric hammer 1 to form the test hole, and when the display screen 51 of the infrared rangefinder 5 reaches the required measurement depth, release the power switch and pull out the drill rod 3 to perform the compaction density test of the compacted concrete nuclear density meter.
