Description

Technical Field

[0001] This invention belongs to the field of municipal road inspection and relates to a drilling and core sampling device for municipal road inspection. Background Technology

[0002] In municipal inspections, to prevent shoddy workmanship during road construction, it is necessary to conduct relevant tests on the road surface after completion. Some key data require road sampling. In addition, to measure the thickness of the concrete road pouring, it is necessary to drill core samples from the road. Therefore, core drilling machines have been developed and are widely used in municipal inspection centers across the country.

[0003] When drilling samples from municipal roads, existing drilling devices can only drill a circular hole in the road, leaving the sample inside. Other tools are needed to remove the sample, which increases the number of steps, reduces testing efficiency, and makes the device inconvenient to use because the wheels are on the ground during drilling. Summary of the Invention

[0004] In view of this, in order to solve the problems that drilling devices can only drill circular holes in the road, leaving the sample inside the hole, requiring other tools to clamp the sample out, which increases the process and reduces the detection efficiency, and that the device is inconvenient to fix when the wheels are on the ground during drilling, thus making it inconvenient to use, the present invention provides a drilling core sampling device for municipal road inspection.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A municipal road inspection drilling and core sampling device includes:

[0007] The base plate has a round hole in the middle. Two first fixing rods are fixedly connected to the top of the base plate. The top of the two first fixing rods is fixedly connected to the same top plate. The outer wall of the two first fixing rods is slidably fitted with the same moving plate. The sampling tube passes through the inside of the moving plate. The moving plate is equipped with a drive component for driving the sampling tube to rotate.

[0008] The top of the sampling tube is rotatably connected to an operating panel, and the inside of the operating panel is equipped with a clamping component for clamping the sample.

[0009] The base plate has a U-shaped hole inside, and a moving component for installing the moving device is installed inside the U-shaped hole.

[0010] Furthermore, the drive assembly includes a servo motor fixedly connected to the top of the moving plate. The output shaft of the servo motor and the outer wall of the sampling cylinder are both fixedly connected to synchronous pulleys. The outer walls of the two synchronous pulleys are fitted with the same synchronous belt. An electric push rod is fixedly connected to the bottom of the top plate. The piston rod of the electric push rod is fixedly connected to the top of the moving plate, which can help the device complete the drilling process.

[0011] Furthermore, the clamping assembly includes two symmetrically arranged strip holes on the top of the sampling cylinder. A vertical rod slides through the inside of the strip holes, and a reinforcing plate is fixedly connected to the bottom of the vertical rod. A clamping block is fixedly connected to the outer wall of the reinforcing plate, which can ensure the strength of the device and extend its service life.

[0012] Furthermore, a fixed circular plate is fixedly connected inside the operating panel, and an elliptical groove is opened inside the fixed circular plate. The elliptical groove is used in conjunction with two vertical rods. Two symmetrically arranged ear plates are fixedly connected to the outer wall of the operating panel, which can drive the two vertical rods to move closer to each other and clamp the sample.

[0013] Furthermore, the top of the sampling tube has two symmetrically arranged grooves, through which round rods slide. The tops of the two round rods are fixedly connected to the same annular plate. The bottom of the annular plate and the top of the sampling tube are fixedly connected to two symmetrically arranged springs, which are respectively sleeved on the two round rods. The top of the annular plate is fixedly connected to two symmetrically arranged positioning rods. The positioning rods work in conjunction with the ear plate to fix the device and ensure the stability of the clamping.

[0014] Furthermore, the moving component includes a connecting plate that slides through the U-shaped hole. A lower mounting plate is fixedly connected to the bottom of the connecting plate, and an upper mounting plate is fixedly connected to the top of the connecting plate. Four symmetrical moving wheels are fixedly connected to the bottom of the lower mounting plate, which can help the device move and reduce the workload of workers.

[0015] Furthermore, four symmetrical support blocks are fixedly connected to the bottom of the base plate, and support plates are fixedly connected to the bottom of the support blocks to support the device and ensure its stability.

[0016] Furthermore, a second fixing rod is fixedly connected to one side of the connecting plate. An elliptical block is rotatably sleeved on the outer wall of the second fixing rod. The bottom and top of the elliptical block are provided with flat surfaces that cooperate with the base plate and the lower mounting plate, which can help the device to be adjusted from the moving state to the braking state, facilitating drilling operations.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The municipal road inspection drilling and core sampling device disclosed in this invention can be moved normally through the moving component, reducing the workload of workers, and the device can be adjusted to a fixed state by rotating the elliptical block, which facilitates the braking of the device.

[0031] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] like Figures 1-2 The municipal road inspection drilling and core sampling device shown has a circular hole 15 in the middle of the base plate 5. Two first fixing rods 9 are fixedly connected to the top of the base plate 5. The top of the two first fixing rods 9 is fixedly connected to the same top plate 1. The outer wall of the two first fixing rods 9 is slidably fitted with the same moving plate 8. The sampling cylinder 3 is rotatably passed through the inside of the moving plate 8. The inside of the moving plate 8 is provided with a drive component for driving the sampling cylinder 3 to rotate.

[0033] like Figure 4 As shown, the drive assembly includes a servo motor 10 fixedly connected to the top of the moving plate 8. The output shaft of the servo motor 10 and the outer wall of the sampling cylinder 3 are both fixedly connected to synchronous pulleys 19. The outer walls of the two synchronous pulleys 19 are fitted with the same synchronous belt 18. An electric push rod 2 is fixedly connected to the bottom of the top plate 1. The piston rod of the electric push rod 2 is fixedly connected to the top of the moving plate 8. When the servo motor 10 is started, the output shaft of the servo motor 10 drives the synchronous pulleys 19 to rotate, which in turn drives the sampling cylinder 3 to rotate through the synchronous belt 18. The bottom of the sampling cylinder 3 is serrated to facilitate the sampling process. At the same time, the electric push rod 2 is started, and the piston rod of the electric push rod 2 drives the moving plate 8 to move down. The moving plate 8 drives the sampling cylinder 3 to move down, which helps to complete the drilling operation.

[0034] like Figure 5 , 6As shown, an operating plate 23 is rotatably connected to the top of the sampling cylinder 3. The operating plate 23 contains a clamping assembly for gripping samples. The clamping assembly includes two symmetrically arranged strip-shaped holes 21 on the top of the sampling cylinder 3. A vertical rod 28 slides through the inside of each strip-shaped hole 21. A reinforcing plate 27 is fixedly connected to the bottom of the vertical rod 28. A clamping block 22 is fixedly connected to the outer wall of the reinforcing plate 27. The operating plate 23 contains a clamping block 22. Figure 7 The fixed circular plate 31 shown has an elliptical groove 32 inside. The elliptical groove 32 works in conjunction with two vertical rods 28. When the operating plate 23 rotates, it can drive the fixed circular plate 31 to rotate, so that the long side of the elliptical groove 32 contacts the vertical rod 28. When adjusted to contact the short side of the vertical rod 28, the two vertical rods 28 can be moved closer to the middle. The vertical rods 28 move inside the strip hole 21, which in turn drives the reinforcing plate 27 to move. The reinforcing plate 27 drives the clamping block 22 to move, and the two clamping blocks 22 clamp the sample. At this time, the sampling cylinder 3 can be taken out, and the sample can be taken out at the same time.

[0035] Two symmetrically arranged ear plates 29 are fixedly connected to the outer wall of the operating plate 23. Two symmetrically arranged grooves 20 are opened on the top of the sampling cylinder 3. A round rod 26 slides through the inside of the groove 20. The top of the two round rods 26 is fixedly connected to the same annular plate 30. Two symmetrically arranged springs 25 are fixedly connected between the bottom of the annular plate 30 and the top of the sampling cylinder 3. The two springs 25 are respectively sleeved on the two round rods 26. Two symmetrically arranged positioning rods 24 are fixedly connected to the top of the annular plate 30. The positioning rods 24 cooperate with the ear plates 29. After drilling is completed, the annular plate 30 can be pressed down. The annular plate 30 drives the round rods 26 to move vertically downward. The round rods 26 enter the inside of the groove 20 and squeeze the springs 25. At this time, the positioning rods 24 no longer block the ear plates 29. The operating plate 23 can be rotated. The operating plate 23 drives the ear plates 29 to rotate and move the ear plates 29 above the positioning rods 24. The annular plate 30 is released. At this time, the positioning rods 24 enter the inside of the ear plates 29 and can brake the operating plate 23.

[0036] like Figure 3As shown, a U-shaped hole 16 is provided inside the base plate 5. A moving component for the moving device is disposed inside the U-shaped hole 16. The moving component includes a connecting plate 17 that slides through the U-shaped hole 16. A lower mounting plate 6 is fixedly connected to the bottom of the connecting plate 17, and an upper mounting plate 7 is fixedly connected to the top of the connecting plate 17. Four symmetrically arranged moving wheels 4 are fixedly connected to the bottom of the lower mounting plate 6. Four symmetrically arranged support blocks 14 are fixedly connected to the bottom of the base plate 5. A support plate 11 is fixedly connected to the bottom of the support blocks 14. A second fixing rod 12 is fixedly connected to one side of the connecting plate 17. An elliptical block 13 is rotatably fitted onto the outer wall of the second fixed rod 12. The bottom and top of the elliptical block 13 are provided with planes that cooperate with the base plate 5 and the lower mounting plate 6. After the device is moved to a suitable position and the position is determined, the elliptical block 13 can be rotated. The elliptical block 13 rotates around the second fixed rod 12. At this time, the elliptical block 13 can be adjusted to a horizontal state, so that the short side of the elliptical block 13 abuts against the lower mounting plate 6 and the base plate 5. The base plate 5 moves down under the action of gravity, thereby driving the support block 14 and the support plate 11 to move down. The support plate 11 contacts the ground, ensuring the stability of the device.

[0037] When using this municipal road inspection drilling and core sampling device, move the device to a suitable position. After the position is determined, rotate the elliptical block 13. The elliptical block 13 rotates around the second fixed rod 12. At this time, the elliptical block 13 can be adjusted to a horizontal state, so that the short side of the elliptical block 13 can abut against the lower mounting plate 6 and the base plate 5. The base plate 5 moves down under the action of gravity, which in turn drives the support block 14 and the support plate 11 to move down. The support plate 11 contacts the ground to ensure the stability of the device.

[0038] Start the servo motor 10. The output shaft of the servo motor 10 drives the synchronous pulley 19 to rotate, which in turn drives the sampling cylinder 3 to rotate through the synchronous belt 18. The bottom of the sampling cylinder 3 is serrated to facilitate the sampling process. At the same time, start the electric push rod 2. The piston rod of the electric push rod 2 drives the moving plate 8 to move down. The moving plate 8 drives the sampling cylinder 3 to move down, which can help complete the drilling operation.

[0039] After drilling is completed, the annular plate 30 can be pressed down. The annular plate 30 drives the round rod 26 to move vertically downward. The round rod 26 enters the interior of the groove 20 and squeezes the spring 25. At this time, the positioning rod 24 no longer blocks the ear plate 29. The operating plate 23 can be rotated. The operating plate 23 drives the ear plate 29 to rotate and move the ear plate 29 above the positioning rod 24. Release the annular plate 30. At this time, the positioning rod 24 enters the interior of the ear plate 29 and can brake the operating plate 23.

[0040] Furthermore, when the operating plate 23 rotates, it can drive the fixed circular plate 31 to rotate. The fixed circular plate 31 makes the long side of the elliptical groove 32 contact the vertical rod 28. Adjusting it so that the short side contacts the vertical rod 28, the two vertical rods 28 can be brought closer to the middle. The vertical rods 28 move inside the strip hole 21, and then the vertical rods 28 drive the reinforcing plate 27 to move. The reinforcing plate 27 drives the clamping block 22 to move. The two clamping blocks 22 clamp the sample. At this time, the sampling tube 3 can be taken out, and the sample can be taken out at the same time.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
