Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a sampling drilling device for road and bridge concrete quality detection. Background Art

[0002] Roads and bridges are mostly built with concrete made by mixing cement, sand, stone and water. Since the quality of concrete is closely related to safety hazards, it is often necessary to use a sampling drilling device to drill holes in the concrete to take samples in order to test its quality.

[0003] An existing sampling drilling device for road and bridge concrete quality inspection lacks mud dust protection function during use. When the operator uses the drilling device to drill and sample, the intense friction between the drill bit and the concrete requires the use of cooling water to cool the drill bit. Therefore, the water and the dust generated by the drilling are mixed to form mud. The mud will splash everywhere through the rotation of the drill bit, and the mud will pollute the operator and affect the drilling operation.

[0004] For this purpose, a sampling drilling device for road and bridge concrete quality detection is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1: Two first support rods 8 and two second support rods 15 are respectively installed inside the base 1, the outer sliding sleeves of the two first support rods 8 are provided with a first slide plate 5, and the outer sliding sleeves of the two first support rods 8 and the second support rods 15 are provided with a second slide plate 10, a protective cover 6 is installed on one side of the first slide plate 5, and a first through hole 18 is opened on the top of the protective cover 6, a drill rod 7 is movably installed on one side of the bottom of the second slide plate 10, and the bottom end of the drill rod 7 passes through the inside of the protective cover 6 through the first through hole 18, a second screw rod 3 is movably installed inside the base 1, and the second screw rod 3 is connected to the inside of the first slide plate 5 by threaded engagement, and a second rocker arm 11 is installed on the top of the base 1, and the output end of the second rocker arm 11 is connected to the top of the second screw rod 3.

[0022] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the second screw rod 3 can be driven to rotate by rotating the second rocker arm 11. Since the second screw rod 3 is connected to the first slide plate 5 by threaded engagement, and the first slide plate 5 has a sliding sleeve inside thereof arranged on the outside of the first support rod 8, when the second screw rod 3 rotates, the first slide plate 5 will slide up and down along the installation direction of the second screw rod 3 and the first support rod 8. Since a protective cover 6 is installed on one side of the first slide plate 5, when drilling sampling is performed, the protective cover 6 can be driven to move downward by rotating the second rocker arm 11, so that the bottom of the protective cover 6 is fitted with the concrete surface. Since a first through hole 18 is provided at the top of the protective cover 6, and the drill rod 7 is used in conjunction with the first through hole 18, when drilling, the bottom end of the drill rod 7 will extend into the protective cover 6 through the first through hole 18, thereby drilling a hole on the concrete surface. The dust and mud generated during the drilling process will be blocked by the protective cover 6, so as to avoid the situation where the mud and dust are scattered, thereby ensuring a clean and tidy working environment and improving the efficiency of drilling sampling.

[0023] Embodiment 2: A second through hole 19 is opened inside the second skateboard 10, and the second screw rod 3 is movably installed inside the second through hole 19, a driving motor 9 is installed on one side of the top of the second skateboard 10, and the output end of the driving motor 9 is connected to the top of the drill rod 7, a non-slip pad 16 is installed at the bottom of the protective cover 6, and a cutting tooth 17 is installed at the bottom of the drill rod 7, four fixed casters 4 are installed at the bottom of the base 1, and the four fixed casters 4 are respectively located at the four corners of the bottom of the base 1, a first screw rod 2 is movably installed inside the base 1, and the first screw rod 2 is connected to the second skateboard 10 by threaded engagement, a first rocker 12 is installed on the top of the base 1, and the output end of the first rocker 12 is connected to the top of the first screw rod 2, a generator 13 is installed on one side of the top of the base 1, and a handle 14 is installed on one side of the base 1, and the generator 13 is used in conjunction with the driving motor 9.

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first screw rod 2 can be driven to rotate by rotating the first rocker 12. Since the first screw rod 2 and the second slide plate 10 are connected by threaded engagement, and the second slide plate 10 is internally slidably sleeved on the outside of the first support rod 8 and the second support rod 15, when the first screw rod 2 rotates, it will drive the second slide plate 10 to move up and down along the installation direction of the first support rod 8 and the second support rod 15. Since the second slide plate 10 is provided with a second through hole 19, the second through hole 19 can avoid being restricted by the second screw rod 3 during the movement of the second slide plate 10, so that the second slide plate 10 can be moved along the second screw rod 3. 3 moves normally on the outside, thereby controlling the rise and fall of the drill rod 7, so as to drill holes in the concrete surface. The generator 13 can power the drive motor 9, and the rotation of the output end of the drive motor 9 can drive the drill rod 7 to rotate. Since the bottom end of the drill rod 7 is equipped with a cutting tooth 17, the rotation of the drill rod 7 can drive the cutting tooth 17 to rotate, and the concrete layer can be cut by the rotation of the cutting tooth 17 to take samples. The fixed caster 4 installed at the bottom end of the base 1 can facilitate the movement of the entire device, and the handle 14 installed on one side of the base 1 can facilitate the operator to control the entire device.

[0025] Working principle: when in use, the entire fixed caster 4 is moved to the specified position, and then the fixed caster 4 is locked, and then the second screw rod 3 can be driven to rotate by rotating the second rocker 11. Since the second screw rod 3 and the first slide plate 5 are connected by threaded engagement, and the first slide plate 5 has a sliding sleeve arranged on the outside of the first support rod 8, when the second screw rod 3 rotates, the first slide plate 5 will slide up and down along the installation direction of the second screw rod 3 and the first support rod 8. Since a protective cover 6 is installed on one side of the first slide plate 5, when drilling sampling is performed, the protective cover 6 can be driven to move downward by rotating the second rocker 11, so that the bottom of the protective cover 6 fits with the concrete surface, and then the belt can be driven by rotating the first rocker 12 The second slide plate 10 is moved up and down along the installation direction of the first support rod 8 and the second support rod 15, so as to control the rise and fall of the drill rod 7. As the second slide plate 10 continues to descend, the bottom end of the drill rod 7 will extend into the protective cover 6 through the first through hole 18, so as to contact the concrete surface. The drill rod 7 can be driven to rotate by rotating the output end of the driving motor 9. Since the bottom end of the drill rod 7 is equipped with cutting teeth 17, the cutting teeth 17 can be driven to rotate by the rotation of the drill rod 7. The concrete layer can be cut by the rotation of the cutting teeth 17 for sampling. The dust and mud generated during the drilling process will be blocked by the protective cover 6 to avoid the scattering of mud and dust, thereby ensuring the cleanliness of the working environment and improving the efficiency of drilling sampling.
