Description

Technical Field

[0001] This utility model belongs to the field of engineering equipment technology, and specifically relates to a highway thickness measuring instrument. Background Technology

[0002] Highways are very important transportation facilities, and there are many standards for highway paving. Thickness is one of the important indicators of highway paving. After the highway is paved, the supervisors will drill a certain amount of road samples from different points on the highway and measure the thickness of the drilled samples to reflect the thickness of the highway paving.

[0003] Obtaining highway samples requires drilling on the highway using a highway sample thickness detector. The working principle is that the drill barrel is driven by a drive motor to rotate. The drill barrel drills into the ground and passes through the paved highway. The drilled highway sample will get stuck inside the drill barrel. Users need to use tools such as hammers to hammer the drill barrel to force the highway sample out of the drill barrel. It can be seen that it is quite troublesome to remove the highway sample from the drill barrel. Utility Model Content

[0004] The purpose of this invention is to provide a highway thickness measuring instrument to solve the problem that the drill barrel of a traditional highway thickness measuring instrument can get stuck in the drilled highway sample, making it difficult for inspectors to remove the highway sample from the drill barrel.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A road thickness measuring instrument, comprising:

[0007] Mounting frame, including support columns and a top plate connected to the support columns;

[0008] The mounting plate is slidably connected to the support column, and a drive motor is connected to the support column. A drill barrel is slidably engaged at the end of the output shaft of the drive motor, and a side rod is fixedly connected to the outer wall of the drill barrel.

[0009] A connecting plate is slidably connected to the support column, and the connecting plate is provided with a clamping assembly and a ring, and the ring is fixedly connected with abutments in a ring array.

[0010] Preferably, a drive block is fixedly connected to the end of the output shaft of the drive motor, the upper end of the drill barrel is sleeved on the drive block, and a slide rod is provided on the outer wall of the drive block, and a slide groove is provided on the inner wall of the drill barrel for the slide rod to engage and slide.

[0011] Preferably, the clamping assembly includes an outer cylinder fixedly mounted on the connecting plate and a retaining ball disposed inside the outer cylinder. A pressure plate is connected to the outer cylinder by adjusting bolts, and a retaining ring located inside the outer cylinder is connected to the pressure plate. The retaining ring has a triangular cross-section, and the downward displacement of the retaining ring pushes the retaining ball out of the outer cylinder and abuts against the drill barrel.

[0012] Preferably, the bottom of the inner wall of the outer cylinder is provided with a protrusion to prevent the ball from detaching.

[0013] Preferably, the top plate is rotatably connected to a lead screw, which is threadedly connected to the mounting plate.

[0014] Preferably, a brake bolt is threaded onto the connecting plate, and the end of the brake bolt can penetrate the connecting plate and abut against the support column.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, by setting up a side rod, a ring, and a stop block, allows the user to lift the drive motor and drill cylinder via a mounting plate when the drilled sample is engaged inside the drill cylinder. This causes the drill cylinder to suspend below the drive motor, with the side rod resting on the ring. When the drive motor rotates the drill cylinder, the side rod rotates against the ring, and the stop block pushes the side rod upward. When the side rod disengages from the stop block, the weight of the drill cylinder causes the side rod to re-engage against the ring, thus achieving the reciprocating motion of the side rod. The side rod then enables the drill cylinder to move up and down, allowing the drilled sample to quickly detach from the reciprocating drill cylinder under inertia. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 As shown, a highway thickness measuring instrument is characterized by comprising:

[0025] The mounting frame includes a support column 1 and a top plate 2 connected to the support column 1;

[0026] Mounting plate 3 is slidably connected to support column 1, and drive motor 5 is connected to support column 1. Drill cylinder 7 is slidably engaged at the output shaft end of drive motor 5. Drill cylinder 7 has a retaining tooth at the bottom to help the rotating drill cylinder 7 quickly cut the road. Side rod 17 is fixedly connected to the outer wall of drill cylinder 7. Drive block 6 is fixedly connected to the output shaft end of drive motor 5. The upper end of drill cylinder 7 is sleeved on drive block 6, and slide rod 61 is provided on the outer wall of drive block 6. Slide groove 71 is provided on the inner wall of drill cylinder 7 for slide rod 61 to engage and slide. The rotating drive block 6 can drive drill cylinder 7 to rotate through slide rod 61 and slide groove 71. At the same time, drive block 6 and slide rod 61 can move up and down along slide groove 71.

[0027] The connecting plate 8 is slidably connected to the support column 1, and the connecting plate 8 is provided with a clamping assembly and a ring 15. The ring 15 is fixedly connected with abutment blocks 16 in a ring array.

[0028] As can be seen from the above, by setting the side rod 17, the ring 15 and the stop block 16, when the drilled sample is stuck inside the drill barrel 7, the user can lift the drive motor 5 and the drill barrel 7 through the mounting plate 3, so that the drill barrel 7 hangs below the drive motor 5 and the side rod 17 is attached to the ring 15. When the drive motor 5 drives the drill barrel 7 to rotate, the side rod 17 will rotate while attached to the ring 15. The stop block 16 will push the side rod 17 upward. When the side rod 17 is disengaged from the stop block 16, the gravity of the drill barrel 7 will cause the side rod 17 to re-attach to the ring 15, thereby realizing the reciprocating motion of the side rod 17. The reciprocating motion of the drill barrel 7 is realized through the side rod 17, thereby allowing the drilled sample to quickly detach from the reciprocating drill barrel 7 under the action of inertia.

[0029] Please see Figure 2 - Figure 4As shown, the clamping assembly includes an outer cylinder 10 fixedly mounted on the connecting plate 8 and a retaining ball 12 disposed inside the outer cylinder 10. A pressure plate 11 is connected to the outer cylinder 10 by an adjusting bolt 14. An abutment ring 13 located inside the outer cylinder 10 is connected to the pressure plate 11. The abutment ring 13 has a triangular cross-section. The downward displacement of the abutment ring 13 pushes the retaining ball 12 out of the outer cylinder 10 and abuts against the drill barrel 7. To prevent the retaining ball 12 from clamping too tightly, the user can slightly adjust the position of the retaining ball 12 so that the retaining ball 12 can both restrict the position of the drill barrel 7 and prevent it from being clamped and unable to rotate.

[0030] The end of the drill barrel 7 is far from the output shaft of the drive motor 5. To prevent the end of the drill barrel 7 from shaking during rotation, the user can slide the connecting plate 8 to a suitable height position of the support column 1, and then rotate the adjusting bolt 14 to change the distance between the pressure plate 11 and the outer cylinder 10. As the distance between the pressure plate 11 and the outer cylinder 10 gradually decreases, the pressure plate 11 will drive the abutment ring 13 to be inserted into the gap between the ball clamp 12 and the outer cylinder 10. The inclined surface of the abutment block 13 will push the ball clamp 12, forcing part of the ball clamp 12 to protrude out of the outer cylinder 10 and abut against the drill barrel 7 inserted in the middle of the outer cylinder 10. As multiple balls clamp 12 abut against the outside of the drill barrel 7, the drill barrel 7 will not swing during the active process due to the restriction of the balls clamp 12, which can stabilize the axial position of the drill barrel 7 and help the drill barrel 7 to drill more complete road samples.

[0031] The bottom of the inner wall of the outer cylinder 10 is provided with a protrusion to prevent the ball 12 from dislodging, thus avoiding the ball 12 from rolling away from the outer cylinder 10.

[0032] The top plate 2 is rotatably connected to a lead screw 4, which is threadedly connected to the mounting plate 3. Users can rotate the lead screw 4 via the handrail, thereby causing the mounting plate 3 to slide up and down on the lead screw 4, making it convenient for users to adjust the position of the drive motor 5 by adjusting the position of the mounting plate 3.

[0033] A brake bolt 9 is threaded onto the connecting plate 8, and the end of the brake bolt 9 can penetrate the connecting plate 8 and abut against the support column 1. The user can rotate the brake bolt 9 to make it abut against the support column 1, and the friction between the brake bolt 9 and the support column 1 restricts the connecting plate 8 from sliding on the support column 1.
