Description

Technical Field

[0001] The invention relates to the technical field of road surface detection sampling equipment, and more specifically to a drilling sampling device for cement road surfaces. Background Art

[0002] Cement pavement, also known as concrete pavement, is a road surface built with concrete materials. Its advantages include durability, compression resistance, skid resistance, high temperature resistance, low maintenance cost and long service life. Cement pavement is usually made of a mixture of cement, sand, gravel and water. After vibration and compaction, a solid surface is formed. The most important link after the road is built is the test and inspection work. At the same time, it is also an important part of the quality management, control and acceptance of road engineering. The drilling sampling device is widely used in roads, airports, ports, docks, dams and other concrete and asphalt pavement essential testing equipment. It is mainly used to drill test cores of concrete and asphalt concrete for compression and demolition resistance experiments;

[0003] Although the existing drilling sampling devices can effectively drill and sample the road surface, since the sample diameter is relatively close to the sampling tube diameter, it is difficult to remove the sample after sampling, which is very inconvenient. In addition, a large amount of mud will be generated during the drilling sampling, and the mud will splash as the sampling tube rotates, thereby contaminating the surface of the device and the clothes of the construction workers. In addition, when drilling, the device will produce a large vibration due to the drilling, and the vibration affects the overall stability of the device, and even causes the device to move, requiring manual assistance to fix it, which increases the labor intensity of the workers. At the same time, when the workers hold the device to fix it, they may be injured due to the vibration of the device, which poses certain safety hazards. Summary of the invention

[0024] Reference Figure 1-Figure 7 As shown, the present invention provides a drilling sampling device for cement pavement, including a main support frame 1, characterized in that: the four corners of the bottom of the main support frame 1 are fixedly connected to support legs 2, the bottoms of the support legs 2 are movably connected to moving wheels 3, the two sides of the surface of the main support frame 1 are fixedly connected to positioning frames 4, the two sides of the top of the main support frame 1 are fixedly connected to support rods 5, the two sides of the inside of the main support frame 1 are fixedly connected to tension springs 6, the adjacent ends of the tension springs 6 are fixedly connected to protective shells 7, the top of the support rods 5 is fixedly connected to a rectangular top plate 8, the inner position of the rectangular top plate 8 is fixedly connected to a positioning bracket 9, and the top of the positioning bracket 9 is fixedly connected to a protective shell 7.

[0025] In this embodiment: by providing a tension spring 6, a protective shell 7, and a wire rope 16, it is beneficial to stop the wire rope 16 from pulling the protective shell 7 when the drill pipe body 15 is lowered for drilling and sampling, so that the tension spring 6 pushes the protective shell 7 to wrap the drill pipe body 15, so that mud, gravel and other debris generated by the drill pipe body 15 during drilling are blocked, preventing splashing pollutants from polluting equipment and construction personnel.

[0026] Reference Figure 2-Figure 4 As shown, a telescopic rotating rod 17 is movably sleeved inside the positioning frame 4, and a rectangular support plate 18 is movably connected to the bottom of the telescopic rotating rod 17. Both sides of the top of the rectangular support plate 18 are fixedly connected to limiting cylindrical rods 19, and the surfaces of the limiting cylindrical rods 19 are movably sleeved on both sides of the positioning frame 4.

[0027] In this embodiment, by providing a rectangular support plate 18, a limiting cylindrical rod 19, and a telescopic rotating rod 17, it is beneficial for the rectangular support plate 18 to be pushed by the telescopic rotating rod 17 when the drilling sampling device is working, so that the rectangular support plate 18 is extended and retracted under the restriction of the limiting cylindrical rod 19, thereby making the drilling sampling device more stable when working as a whole, reducing the labor intensity of manual labor, and reducing the occurrence of safety hazards.

The bottom position of the servo motor 10 is transmission-connected to a lifting screw 1001.

[0029] In this embodiment, by providing a rectangular top plate 8 and a support rod 5, it is helpful to limit the overall position of the lifting bracket 11 when the lifting bracket 11 is lifted, so that the lifting bracket 11 can be lifted smoothly to complete the drilling sampling.

[0031] In this embodiment, by providing a lifting bracket 11 and a rectangular slide rail 1103, it is beneficial to limit the position of the lifting bracket 11 through the rectangular slide rail 1103 when the lifting bracket 11 is lifted, so that the drilling sampling is more stable.

[0032] Reference Figure 7 As shown, vacuum pumps 20 are fixedly connected to both sides of the top of the cooling water spray box 14, connecting pipes 21 are fixedly connected to the top of the vacuum pump 20, and the other ends of the connecting pipes 21 are fixedly connected to the top of the drill pipe body 15. A water storage cavity 1401 is provided inside the cooling water spray box 14, neatly arranged spray heads 1402 are provided at the bottom of the cooling water spray box 14, and a rubber plug 1403 is movably connected to one side of the top of the cooling water spray box 14.

[0033] In the present embodiment, by providing a vacuum pump 20 and a connecting pipe 21, it is advantageous to take out samples from the cement pavement. By turning on the vacuum pump 20, the vacuum pump 20 extracts the air inside the drill pipe body 15 through the connecting pipe 21, thereby forming a negative pressure inside the drill pipe body 15, so that the sample inside the drill pipe body 15 is adsorbed, and the sample can follow the drill pipe body 15 to leave the cement pavement, thereby completing a rapid sampling work and increasing the convenience of operation.

[0034] Reference Figure 7 As shown, a drill pipe inner cavity 1501 is opened inside the drill pipe body 15, and neatly arranged cutting teeth 1502 are opened around the bottom of the drill pipe body 15.

[0035] In this embodiment, by providing neatly arranged cutting teeth 1502, it is beneficial to drill holes in the cement road surface more quickly during drilling sampling, thereby increasing the sampling speed and saving a lot of time.

[0036] The working principle of the present invention is as follows: first, when in use, the main support frame 1 and the support leg 2 are pushed, so that the moving wheel 3 inside the support leg 2 fixed at the bottom of the main support frame 1 rotates, so that the main support frame 1 and the support leg 2 move to the position where drilling and sampling are required, and then the telescopic rotating rod 17 is rotated so that the rectangular support plate 18 at the bottom of the telescopic rotating rod 17 descends due to the rotation of the telescopic rotating rod 17. At this time, the rectangular support plate 18 is smoothly lowered under the restriction of the limiting cylindrical rod 19, so that the rectangular support plates 18 on both sides of the main support frame 1 raise the drilling and sampling device as a whole, so that the moving wheel 3 at the bottom of the support leg 2 is away from the ground, and then the servo motor 10 is turned on so that the servo motor 10 drives the lifting screw 1001 to The top of the positioning bracket 9 is operated, and then the lifting screw 1001 rotates inside the lifting threaded hole 1102 so that the auxiliary bracket 1101 descends under the restriction of the rectangular slide rails 1103 on both sides of the lifting bracket 11. At this time, the descent of the rectangular slide rails 1103 causes the steel wire rope 16 to stop pulling the protective shell 7. Then, due to the lack of the pulling of the steel wire rope 16, the tension spring 6 pushes the protective shell 7. At this time, the drill pipe body 15 at the bottom of the drill shaft body 13 inside the lifting bracket 11 reaches the internal position of the protective shell 7. At this time, the protective shell 7 wraps the cooling water spray box 14 and the drill pipe body 15. At this time, the drilling motor 12 and the vacuum pump 20 on the top of the cooling water spray box 14 are turned on. At this time, the drilling motor 12 drives the drill shaft body 13 to rotate, and then the drill shaft body 13 drives the cooling water spray box 14 and the drill pipe body 15 to rotate, so that the cutting teeth 1502 drill holes in the cement road surface, and then the vacuum pump 20 is started to allow the air inside the drill pipe cavity 1501 to enter the vacuum pump 20 through the connecting pipe 21, and then the vacuum pump 20 injects the gas into the water storage cavity 1401 opened in the cooling water spray box 14, so that the water source in the water storage cavity 1401 is sprayed through the sprinkler head 1402, so that the temperature of the surface of the drill pipe body 15 caused by drilling is reduced, and then the gravel and mud generated by the drilling of the drill pipe body 15 are shielded by the protective shell 7 to prevent the gravel and mud from being Mud splashing causes equipment and construction workers to be contaminated by foreign objects. Then, after the drilling sampling is completed, the sample inside the drill pipe inner cavity 1501 is discharged due to the air inside the drill pipe inner cavity 1501, so that a negative pressure is formed inside the drill pipe inner cavity 1501, so that the sample inside the drill pipe inner cavity 1501 is adsorbed, and then the servo motor 10 is turned on in reverse so that the servo motor 10 drives the lifting bracket 11 to rise. At this time, the lifting of the lifting bracket 11 pulls the wire rope 16, and then the wire rope 16 pulls the protective shell 7, so that the protective shell 7 squeezes the tension spring 6 to open, and then the drill shaft body 13 drives the drill pipe body 15 to rise, and then the sample inside the drill pipe inner cavity 1501 can be taken out.

[0037] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
