Description

Technical Field

[0001] This utility model relates to the technical field of soil drilling, specifically a high-frequency hammering device. Background Technology

[0002] In the construction of sluice gates in water conservancy projects, piezometers need to be installed at specific locations on the gate to ensure the safety of the gate structure and the accuracy of seepage monitoring. Water drilling is commonly used for constructing the piezometer installation holes, as this technique offers advantages such as precise positioning, high-quality borehole formation, and minimal disturbance to the structure.

[0003] In existing technologies, some hammering equipment uses an adjustable structure, but under high-frequency impact conditions, the connecting parts may loosen or be damaged due to repeated stress, affecting the construction quality. Utility Model Content

[0004] The purpose of this invention is to provide a high-frequency hammering device to solve the problem that connecting parts may loosen or be damaged due to repeated stress under high-frequency impact conditions.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a high-frequency hammering device, comprising two connecting plates, both of which are disposed at one end of a fixed rod. Connecting columns are fixed on both sides of the connecting plates respectively. Insertion holes are opened on the surface of the connecting columns. An extension tube is provided at one end of the fixed rod, and a hammering rod is provided at one end of the extension tube. Sleeve grooves are opened at the two ends of the fixed rod and the hammering rod that are close to each other. The connecting columns are slidably inserted into the sleeve grooves. Two fixing holes are opened on the inner wall of the sleeve grooves. Fixing pins are inserted into the fixing holes, and a first nut is threaded to one end of the fixing pins.

[0006] Preferably, a connecting rod is provided at one end of the fixing rod, a positioning plate is fixed at one end of the connecting rod, an installation plate is fixed on one side of the positioning plate, a connecting folding plate is fixed at one end of the fixing rod, the installation plate and the connecting folding plate are rotatably arranged, a connecting bolt is inserted into the connecting folding plate, the installation plate and the connecting folding plate are hinged by the connecting bolt, and a second nut is threaded to one end of the connecting bolt.

[0007] Preferably, a plurality of triangular plates are fixed to one side of the connecting plate, and one side of the triangular plates is fixed to the surface of the fixing rod. A plurality of reinforcing plates are fixed to one side of the positioning plate, and one side of the reinforcing plates is fixed to the surface of the connecting rod.

[0008] Preferably, the wall thickness of the extension tube is 5mm, and the length of the extension tube is 80cm-100cm.

[0009] Preferably, the hammer head at one end of the hammering rod is a conical steel product, the diameter of the hammer head is 10cm, and the length of the hammer head is 15cm, used for hammering soil layers.

[0010] Preferably, the length of the fixing pin is 12cm, and the surface of the fixing pin is galvanized for connecting various rods.

[0011] Compared with existing technologies, a high-frequency hammering device employing the above-mentioned technical solution has the following beneficial effects:

[0012] 1. The insertion hole adopts an oblong hole structure. When the hammer rod impacts the soil layer downward, the fixing pin will slide upward along the insertion hole, so that the fixing rod, extension tube and hammer rod are completely in contact. At this time, the impact force is directly transmitted by the three, and the fixing pin no longer bears the main load. This design effectively avoids stress concentration of the fixing pin and other connecting parts during the hammering process, and improves the durability and reliability of the overall structure.

[0013] 2. The excavator's robotic arm is connected to the connecting rod. When the excavator's robotic arm applies force to the hammer rod, the connecting plate, based on its hinged structure with the mounting plate and combined with the weight of the hammer rod, achieves real-time dynamic adjustment of the angles of the fixed rod, extension tube, and hammer rod. To enhance the overall structural strength, reinforcing plates and triangular plates are specially designed, effectively improving the load-bearing capacity of the connection node between the fixed rod and the connecting rod, ensuring structural stability during hammering operations.

Detailed Implementation

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3As shown, a high-frequency hammering device includes two connecting plates 2, each disposed at one end of a fixed rod 1. Connecting posts 3 are fixed to both sides of each connecting plate 2. Insertion holes 4 are formed on the surface of each connecting post 3. An extension tube 5, a Φ100 steel pipe, is provided at one end of the fixed rod 1. A hammering rod 10 is provided at one end of the extension tube 5. Sleeve grooves 6 are formed at the two ends of the fixed rod 1 and the hammering rod 10 that are close to each other. The connecting posts 3 are slidably inserted into the sleeve grooves 6. Two fixing holes 7 are formed on the inner wall of the sleeve grooves 6. A fixing pin 8 is inserted inside the fixing hole 7. The fixing pin 8 is a Φ10 galvanized bolt. One end of the fixing pin 8 is threaded with a first nut 9. The wall thickness of the extension tube 5 is 5mm, and the length of the extension tube 5 is 80cm-100cm. The hammer head at one end of the hammer rod 10 is a conical steel product. The diameter of the hammer head of the hammer rod 10 is 10cm, and the length of the hammer head of the hammer rod 10 is 15cm. It is used to hammer the soil layer. The length of the fixing pin 8 is 12cm. The surface of the fixing pin 8 is galvanized and it is used to connect the various rods.

[0020] During use, as the hammer rod 10 strikes downwards, the fixed rod 1, the extension tube 5, and the hammer rod 10 will fit tightly together to form an integrated load-bearing structure. At this time, the main load-bearing part is the steel structure of the three components themselves. Since the insertion hole 4 adopts an oblong hole design, the up and down movement of the hammer rod 10 can drive the fixed pin 8 to slide in the insertion hole 4, thereby dynamically adjusting the force distribution between the fixed rod 1, the extension tube 5, and the hammer rod 10. According to actual needs, the operator can adjust the hammering depth by disassembling and assembling the fixed pin 8 and adding or removing the extension tube 5.

[0021] The insertion hole 4 adopts an oblong hole structure. When the hammer rod 10 impacts the soil layer downward, the fixing pin 8 will slide upward along the insertion hole 4, so that the fixing rod 1, the extension tube 5 and the hammer rod 10 are completely in contact. At this time, the impact force is directly transmitted by the three, and the fixing pin 8 no longer bears the main load. This design effectively avoids stress concentration of the connecting parts such as the fixing pin 8 during the hammering process, and improves the durability and reliability of the overall structure.

[0022] like Figure 1 and Figure 2 As shown, a connecting rod 11 is provided at one end of the fixed rod 1, a positioning plate 12 is fixed at one end of the connecting rod 11, an mounting plate 13 is fixed on one side of the positioning plate 12, a connecting folding plate 15 is fixed at one end of the fixed rod 1, the mounting plate 13 and the connecting folding plate 15 are rotatably configured, a connecting bolt 14 is inserted on the connecting folding plate 15, the mounting plate 13 and the connecting folding plate 15 are hinged by the connecting bolt 14, a second nut 16 is threaded to one end of the connecting bolt 14, several triangular plates 17 are fixed on one side of the connecting folding plate 15, one side of the triangular plates 17 is fixed to the surface of the fixed rod 1, several reinforcing plates 18 are fixed on one side of the positioning plate 12, one side of the reinforcing plates 18 is fixed to the surface of the connecting rod 11.

[0023] During operation, the excavator's robotic arm is connected to the connecting rod 11. When the excavator's robotic arm applies force to the hammer rod 10, the connecting folding plate 15, based on its hinged structure with the mounting plate 13 and combined with the weight of the hammer rod 10, achieves real-time dynamic adjustment of the angles of the fixed rod 1, the extension tube 5, and the hammer rod 10. To enhance the overall structural strength, a reinforcing plate 18 and a triangular plate 17 are specially designed, effectively improving the load-bearing capacity of the connection node between the fixed rod 1 and the connecting rod 11, ensuring structural stability during hammering operations.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
