Description

Technical Field

[0001] The present invention relates to the technical field of cavity verification, and in particular to a cavity verification device capable of displaying drilling footage and drilling speed in real time. Background Art

[0002] Currently, ground-penetrating radar technology has been widely used in the field of non-destructive detection of road defects. Ground-penetrating radar technology can quickly, comprehensively, and accurately "see through" road soil defects such as cavities, looseness, and water-rich soil. During the implementation of road inspection projects, suspected cavities and voids screened out through data analysis require drilling verification.

[0003] During the cavity verification drilling construction process, drillers cannot accurately grasp the drilling footage. When verifying defects near the pipeline, it is easy to damage the underground pipeline, causing huge economic losses and even casualties. At the same time, the drilling speed cannot be controlled during the drilling process, resulting in frequent drill jams or drilling into metal or pipelines without timely detection. Although existing impact drills are equipped with load protection functions, if the drill bit suddenly drills into hard foreign objects, the torque instantly exceeds the maximum tolerance threshold of the mechanical clutch. At this time, the clutch structure of the impact drill may be directly damaged, resulting in the failure of the anti-torsion protection, and the fuselage twists violently. The anti-torsion force far exceeds the tolerance of the human wrist. Summary of the Invention

[0031] A connecting rod 7 is fixed to one side of the sliding rod 4. A sliding plate 8 is fixed to one end of the two connecting rods 7. An air box 9 is fixed to one side of the sliding plate 8, and a handle 10 is fixed to the other side. First air outlet pipes 11 are connected to both side walls of the air box 9. One end of the two first air outlet pipes 11 is connected to a first pneumatic rod, and the first pneumatic rod corresponds to the switch position of the impact drill 1. The protective tube 2 plays a protective role to prevent the splash of gravel during drilling. During drilling, the impact drill 1 is first fixed in the protective tube 2 using the fixing mechanism 6. Then the operator holds the handle to push the impact drill 1 to move. Before pushing the handle to move, gas is first sent into the first pneumatic rod through the air box 9. The first pneumatic rod extends and touches the switch of the impact drill 1, thereby starting the impact drill 1. If an accident occurs, the machine body can rotate within the circular track 5 to prevent the operator's arm from being sprained and improve safety.

[0032] See Figure 4 and Figure 5 The first pneumatic rod includes a first sleeve 12, a first air outlet pipe 11 is connected to the first sleeve 12, a first piston block 13 is provided in the first sleeve 12, a round head push rod 14 made of rubber is fixed on one side of the first piston block 13, and one end of the first piston block 13 extends to the outside of the first sleeve 12, a first spring 15 is sleeved on the round head push rod 14, and the first spring 15 is located inside the first sleeve 12; the internal gas of the air supply box 9 enters the first sleeve 12 through the first air outlet pipe 11, and pushes the first piston block 13 and the round head push rod 14 to move under the action of air pressure, and the first spring 15 is compressed, and the round head push rod 14 contacts the switch of the impact drill 1 to start the impact drill 1, so that the operator's hands will not touch the fuselage. When an accident occurs, the fuselage will twist and separate from the round head push rod 14, and the impact drill 1 can be automatically closed. The extended round head push rod 14 has a certain blocking effect on the fuselage, which can stop the fuselage from rotating as soon as possible, thereby reducing the probability of accidents.

[0033] See Figure 6 and Figure 7The fixing mechanism 6 includes a slider 601 slidably connected to the circular track 5, a fixing plate 602 is symmetrically fixed on the slider 601, a screw 603 is threadedly connected to the fixing plate 602, one end of the screw 603 is fixed to a rubber fixing block 604, and the other end is installed with a knob; a socket 605 is fixed on the adjacent side walls of the two sliders 601, the bottom of the first sleeve 12 is connected to the second air outlet pipe 16, the bottom end of the second air outlet pipe 16 is connected to the second pneumatic rod, the second pneumatic rod includes a second sleeve 17 connected to the second air outlet pipe 16, and two second piston blocks 18 are arranged in the second sleeve 17. The side where the two second piston blocks 18 are close to each other is connected to a second spring 20, and the side walls away from each other are fixed with a round-headed plug rod 19 made of rubber. One end of the round-headed plug rod 19 extends to the outside of the second sleeve 17 and matches the size of the socket 605; the two fixing mechanisms 6 can clamp and fix the front and rear handles of the impact drill 1, and the excess gas in the first sleeve 12 will enter the second sleeve 17 through the second air outlet pipe 16, pushing the two round-headed plug rods 19 to move, and the round-headed plug rods 19 enter the socket 605 of the slider 601, thereby fixing the position of the slider 601, and ensuring the stability of the impact drill 1 during drilling.

[0034] See Figure 8 and Figure 9 1001, and the block 1002 fixes the U-shaped rod 902, so that the operator does not need to pull the U-shaped rod 902 for a long time during the drilling process.

[0035] The working principle of the present invention is as follows: first, the protective tube 2 is moved to the drilling site. The protective tube 2 can be made of transparent plastic to facilitate the operator to observe the working situation. The impact drill 1 is facing the drilling point. A certain amount of air is injected into the air box 9 in advance. The operator pulls the U-shaped rod 902 to drive the piston plate 901 to move, and the gas in the air box 9 can be squeezed into the first air outlet pipe 11. The gas enters the first sleeve 12 through the first air outlet pipe 11. Under the action of air pressure, the first piston block 13 and the round head push rod 14 are pushed to move, the first spring 15 is compressed, and the round head push rod 14 is pushed. The rod 14 contacts the switch of the impact drill 1 to start the impact drill 1, so that the operator's hands do not touch the drill body. Part of the gas will enter the second sleeve 17 through the second outlet pipe 16, pushing the two round-headed plug rods 19 to move. The round-headed plug rods 19 enter the socket 605 of the slider 601, thereby fixing the position of the slider 601 and ensuring the stability of the impact drill 1 during drilling. Finally, the U-shaped rod 902 can enter the groove 1001, and the clamping block 1002 fixes the U-shaped rod 902, so that the operator does not need to hold the U-shaped rod 902 for a long time during the drilling process.

[0036] Then the operator pushes the handle 10, and drives the sliding rod 4 to move through the connecting rod 7, so that the two circular tracks 5 and the impact drill 1 move synchronously to perform drilling operations. The display can receive data from the infrared distance sensor and the speed sensor in real time and display it on the display. At the same time, the speed warning can be set according to experience. The infrared distance sensor is used to grasp the drilling footage in real time to prevent over-drilling from damaging underground pipelines. The speed sensor can sense the drilling speed in real time. When the drilling rig encounters abnormal speed, it can issue a real-time warning to prevent drilling into obstacles such as metal objects and pipelines.

[0037] If an accident still occurs, the fuselage will twist and disengage from the round head push rod 14. At this time, the impact drill 1 can be automatically closed, and the fuselage and the slider 601 can rotate along the circular track 5. The extended round head push rod 14 has a certain blocking effect on the fuselage, which can stop the rotation of the fuselage as soon as possible, reducing the probability of accidents.

However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention.
