DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] An embodiment of a highway construction quality detection device of the present invention is as follows Figures 1 to 7 As shown, it includes a storage box 100 , a chain link 200 , a driving member 300 and a drill bit 400 .

[0021] A guide tube 110 communicating with the interior of the storage box 100 is disposed at the lower side of the storage box 100 . The guide tube 110 is vertically disposed and has spiral guide bars disposed on its inner wall.

[0022] There are a plurality of chain links 200 , and two adjacent chain links 200 slide along the vertical direction and can be hinged around the vertical axis within a preset range.

[0023] A plurality of chain links 200 are sequentially connected to form a continuous chain, one end of the chain is located in the storage box 100 , and the other end extends into the guide tube 110 , and at least one chain link 200 cooperates with the spiral guide bar of the guide tube 110 .

[0024] A guide plate 120 is provided inside the storage box 100 and above the guide cylinder 110. The driving member 300 drives the chain link 200 located in the storage box 100 to move, and when moving to above the guide cylinder 110, it is guided by the guide plate 120 to move downward to cooperate with the spiral guide bar in the guide cylinder 110, and then multiple adjacent chain links 200 form a cylindrical structure coaxial with the guide cylinder 110 in the guide cylinder 110, and the cylindrical structure extends as the number of chain links 200 entering the guide cylinder 110 increases, and rotates while extending; two chain links 200 that form a cylindrical structure and are adjacent in the vertical direction are spirally matched.

[0025] The drill bit 400 is mounted on the lower end of the cylindrical structure.

[0026] When in use, the driving member 300 drives the chain link 200 located in the storage box 100 to move, so that the chain link 200 enters the guide cylinder 110 in turn, and cooperates with the spiral guide bar of the guide cylinder 110 in turn to form a cylindrical structure. As the number of chain links 200 entering the guide cylinder 110 increases, the cylindrical structure becomes longer, and the cylindrical structure rotates as the chain link 200 enters the guide cylinder 110, thereby driving the drill bit 400 to move downward while rotating, thereby drilling and sampling the highway. The cylindrical structure formed by the chain link 200 drives the drill bit 400 to move and rotate, and the drill bit 400 can be drilled into different depths as needed. In theory, as long as the number of chain links 200 is sufficient, the sampling depth can be controlled at will. Compared with the traditional screw or telescopic rod structure, it is not limited by the length of the screw and telescopic rod, and the operation is more flexible; when not working, the chain link 200 can be retracted into the storage box 100 to save space.

[0027] In this embodiment, one side of the chain link 200 is a first arc surface, and the axis of the first arc surface is vertical; the driving member 300 includes a motor 310 and a gear 320; the motor 310 is fixed to the storage box 100, and the output shaft of the motor 310 extends into the cylindrical structure. The gear 320 is fixed to the output shaft of the motor 310, and is used to guide the chain link 200 from the storage box 100 into the guide cylinder 110, and the side of the chain link 200 that is about to enter the guide cylinder 110 from the storage box 100 away from the first arc surface abuts against the inner wall of the storage box 100. Specifically, before the chain link 200 enters the guide cylinder 110, the gear 320 rotates until its teeth abut against the first arc surface of the chain link 200 that has not entered the guide cylinder 110, and the gear 320 pushes the first arc surface when rotating to make the chain link 200 continue to move into the guide cylinder 110, and moves downward under the guidance of the guide plate 120 to cooperate with the spiral guide bar. After the chain link 200 enters the guide cylinder 110, it forms a cylindrical structure with the chain link 200 that previously entered the guide cylinder 110. In some other embodiments, the gear 320 may also have a first tooth groove or an additional block on the first arc surface to cooperate with the gear 320, thereby further causing the chain link 200 to move as the gear 320 rotates.

[0028] In this embodiment, a plurality of second tooth grooves are arranged on the first arc surface in sequence along the vertical direction, and each second tooth groove is spirally arranged; the driving member 300 further includes a stud 330, which is fixed to the output shaft of the motor 310 and is located at the lower side of the gear 320, and is used to cooperate with the second tooth groove on the first arc surface of the chain link 200, and rotate under the drive of the motor 310, thereby driving the cylindrical structure to move downward. The stud 330 is located at the lower side of the gear 320, and will cooperate with the second tooth groove on the first arc surface only after the chain link 200 completely enters the guide cylinder 110.

[0029] In this embodiment, the other side of the chain link 200 facing away from the first arc surface is a second arc surface, the second arc surface is coaxial with the inner wall of the guide cylinder 110, and a first spiral groove 210 for cooperating with the spiral guide bar is provided on the second arc surface. After the chain link 200 enters the guide cylinder 110 from the storage box 100, the first spiral groove 210 cooperates with the spiral guide bar, and then moves along the spiral guide bar driven by the adjacent chain link 200 that enters the guide cylinder 110 first, thereby making room for the next chain link 200 to enter the guide cylinder 110 from the storage box 100.

[0030] In this embodiment, a first step surface that does not extend beyond the second arc surface is provided on the lower side of the second arc surface, and a spiral protrusion 220 is provided on the first step surface; a second step surface that does not extend beyond the first arc surface is provided on the upper side of the first arc surface, and a spiral groove 230 is provided on the second step surface; in the two links 200 that constitute a cylindrical structure and are adjacent in the vertical direction, the first step surface of the link 200 located on the upper side is fitted with the second step surface of the link 200 located on the lower side, and the spiral protrusion 220 on the first step surface cooperates with the corresponding spiral groove 230.

[0031] In this embodiment, the two sides of the link 200 in its moving direction are respectively a first side and a second side, a connecting block 240 is provided on the first side of the link 200, and a connecting groove 250 is provided on the second side of the link 200, the upper and lower ends of the connecting groove 250 are through, the connecting block 240 of the link 200 cooperates with the connecting groove 250 of its adjacent link 200, the connecting block 240 can slide up and down in the connecting groove 250 and can rotate relative to the connecting groove 250 around the vertical axis within a preset range, and when the connecting block 240 cooperates with the connecting groove 250, it will never disengage in the moving direction of the link 200.

[0032] In this embodiment, the drill bit 400 is hollow inside, and a second spiral groove 410 is formed on its inner wall, one end of the second spiral groove 410 is connected with the end of the drill bit 400 away from the ground, and the other end extends to the middle of its inner wall; the spiral protrusion 220 of the chain link 200 that constitutes a cylindrical structure and is located at the lower end of the cylindrical structure is slidably matched with the second spiral groove 410. The drill bit 400 moves downward and rotates with the cylindrical structure to sample the road, and the outer peripheral wall of the sample taken out is cut with an external thread by the second tooth groove of the first arc surface of the chain link 200, which prevents the sample from falling off during the removal process and avoids the mixing of samples at different depths to a certain extent, ensuring the accuracy of the detection.

[0033] In this embodiment, the storage box 100 is a square box, and a guide plate 130 for guiding the movement of the chain is provided in the storage box 100. The height inside the storage box 100 is consistent with the height of the chain link 200. The chain in the storage box 100 is in a reeled state, and the outermost circle of the reeled chain is in contact with the inner wall of the storage box 100. The guide plate 130 limits the moving path of the chain link 200, so that the chain link 200 is evenly reeled in the storage box 100, and the second arc surface of the chain link 200 is always in contact with the guide plate 130 in the storage box 100 before entering the guide cylinder 110.

[0034] In the initial state of a highway construction quality inspection device of the present invention, a plurality of chain links 200 are sequentially connected through a connection block 240 and a connection groove 250 to form a chain, and the chain is rolled up in a storage box 100. The chain has only one layer in the storage box 100 and the second arc surface of the outermost chain abuts against the side wall of the storage box 100. One end of the chain is rolled up to the center of the storage box 100, and the other end is in the guide cylinder 110 and cooperates with the drill bit 400 located in the guide cylinder 110, that is, the spiral protrusions 220 of the plurality of chain links 200 at the other end cooperate with the second spiral grooves 410 on the drill bit 400. When sampling of the highway is required, the guide cylinder 110 is made vertical and the motor 310 is started. The motor 310 drives the chain link 200 to move to the top of the guide cylinder 110 through the gear 320, and then moves downward under the guidance of the guide plate 120 to cooperate with the spiral guide bar, and then moves along the spiral guide bar driven by the adjacent chain link 200 that has entered the guide cylinder 110 first, thereby making room for the next chain link 200 to enter the guide cylinder 110 from the storage box 100. The motor 310 rotates continuously, and drives the chain links 200 to enter the guide cylinder 110 in sequence through the gear 320. The chain links 200 entering the guide cylinder 110 are guided by the spiral guide bar to form a cylindrical structure, and there is a height difference between two adjacent chain links 200 in the vertical direction. The chain link 200 before rotating to be separated from the spiral guide bar cooperates with the chain link 200 above it through the spiral protrusion 220 and the spiral groove 230, and the connecting blocks 240 and the connecting groove 250 of the two adjacent chain links 200 are always in good cooperation. As the number of chain links 200 entering the guide cylinder 110 increases, the cylindrical structure formed is extended while rotating, and the drill bit 400 moves downward while rotating with the cylindrical structure, thereby drilling and sampling the highway. The outer peripheral wall of the sample taken out is cut with an external thread by the second tooth groove of the first arc surface of the chain link 200, which prevents the sample from falling during the removal process, and to a certain extent avoids the mixing of samples of different depths, thereby ensuring the accuracy of the detection.

[0035] After sampling is completed, the cylindrical structure matched with the drill bit 400 is rotated in the reverse direction manually or with a tool to move the chain link 200 back into the storage box 100. The cylindrical structure gradually shortens as the chain link 200 moves, thereby exposing the obtained sample.

[0036] 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 principle of the present invention should be included in the protection scope of the present invention.
