Description

Technical Field

[0001] This utility model relates to the technical field of core sampling devices, specifically a vehicle-mounted mobile road core sampling device. Background Technology

[0002] In road widening inspections, core sampling of the base course, subbase course, or subbase layer is required to determine the structural layer type, thickness, or condition of the road surface. Road coring machines are typically heavy (50-150 kg), and the large number of core samples required, along with the dispersed locations (e.g., highway and urban road surveys), necessitates frequent relocation. Traditional manual handling methods are inefficient and labor-intensive. Furthermore, road coring machines generate significant amounts of dust during drilling, polluting the environment and posing health risks to operators. The high-speed rotation of the drill bit also generates frictional heat, potentially causing thermal damage to the samples and affecting the accuracy of the test results.

[0003] While existing vehicle-mounted sampling devices exist, they generally suffer from complex structures and lack dust removal and cooling functions. The requirements for rapid deployment and environmentally friendly operation are particularly prominent when operating on urban roads or in busy traffic areas. Therefore, there is an urgent need to develop a vehicle-mounted core drilling sampling device that integrates mobility, ease of operation, and environmental friendliness. Utility Model Content

The slide rail body 2 is provided with a sliding groove 21, and the two sliding bars 31 are fixed to the bottom of the sliding seat plate 3. The two sliding bars 31 are slidably disposed in the sliding groove 21, so that the sliding seat plate 3 can slide along the slide rail body 2, thereby allowing the sliding seat plate 3 to partially slide outside the vehicle body 1.

[0029] The sliding seat plate 3 is provided with a lifting platform 52, two lifting cylinders 4 and two fixed guide rods 5. Two lifting sleeves 51 are fixedly connected to the lifting platform 52. Each fixed guide rod 5 passes through a lifting sleeve 51. Each lifting cylinder 4 is provided with a lifting support rod 41.

[0030] The lifting assembly is fixed to the lifting platform 52. The lifting assembly drives the lifting platform 52 to move up and down along the fixed guide rods 5. Specifically, the lifting assembly includes a lifting cylinder 54 and a fixed plate 53. The fixed plate 53 is fixedly connected to the top of the two fixed guide rods 5. The lifting cylinder 54 is fixed to the lifting platform 52, and the telescopic rod of the lifting cylinder 54 is fixed to the bottom of the fixed plate 53. When the telescopic shaft of the lifting cylinder 54 extends, the lifting platform 52 descends; when the telescopic shaft of the lifting cylinder 54 retracts, the lifting platform 52 rises.

[0031] The rotating core drilling assembly includes a drive motor 6 and a core sampling cylinder 61. The drive motor 6 is fixed on the lifting platform 52, and the core sampling cylinder 61 is located below the lifting platform 52. The rotation shaft of the drive motor 6 passes through the lifting platform 52 and is fixedly connected to the core sampling cylinder 61.

The rotating core sampling cylinder 61 can take core samples from the road surface during the process of the lifting assembly driving the lifting platform 52 to descend.

[0032] This vehicle-mounted mobile road core sampling device can be mounted on a vehicle body 1, offering advantages such as convenient mobility and rapid deployment. The sliding seat plate 3 of this device achieves precise positioning through the cooperation of the sliding strip 31 and the slide rail groove 21, ensuring operational stability and eliminating the time required for traditional equipment handling and assembly. Furthermore, the device is simple to operate, saving the time of traditional equipment handling and assembly, and can be operated by a single person, significantly reducing the labor costs of road core sampling.

During the core drilling process of the core sampling cylinder 61, the flexible sealing sleeve 71 automatically conforms to the road surface under the action of the helical spring 7 and the support ring 72, forming a closed space, which can completely suppress dust.

[0035] Furthermore, the sliding seat plate 3 is also provided with two limiting sleeves 74, which are located on both sides of the flexible closed sleeve 71.

A water spray ring 82 is provided at the bottom of the lifting platform 52, the water spray ring 82 surrounds the rotating shaft, and multiple water spray holes 83 are distributed at the bottom of the water spray ring 82. During the core drilling process of the core sampling cylinder 61, the water spray pump 8 supplies water to the water spray ring 82, so that the water spray holes 83 of the water spray ring 82 spray water onto the outer wall of the sampling cylinder 61. This not only suppresses dust, but also cools the high-speed rotating core sampling cylinder 61, avoids thermal damage to the sample, and extends the service life of the drill bit.

The fixing insertion hole 33 passes through the sliding seat plate 3 and the sliding strip 31. A pin can be inserted into the fixing insertion hole 33 to lock the slide rail body 2 and the sliding strip 31. This can keep the device stable during core drilling and transportation, and prevent the sliding seat plate 3 from sliding on the slide rail body 2.

[0039] The working process of this vehicle-mounted mobile road core drilling and sampling device is as follows: After the vehicle body 1 moves to the desired sampling position, the operator pushes the sliding push rod 32 to partially slide the sliding seat plate 3 out of the vehicle body 1, inserts a pin into the fixing hole 33, and passes the pin through the slide rail insertion hole 22 to lock the sliding seat plate 3; then, the operator rotates the handwheel 42 to adjust the lifting support rod 41, so that the support plate 43 at the lower end of the lifting support rod 41 supports the road surface, keeping the sliding seat plate 3 stable; the height of the core drilling sampling cylinder 61 is adjusted by the lifting cylinder 54, so that... Its lower end contacts the ground, releasing the limiting rod 75 so that the flexible sealing sleeve 71 covers the core sampling cylinder 61; the drive motor 6 and the water pump 8 are started, the core sampling cylinder 61 rotates, and the water spray ring 82 sprays water onto the outer wall of the core sampling cylinder 61 through the water spray hole 83; the lifting cylinder 54 slowly presses down the lifting platform 52 until the core sampling cylinder 61 rotates and descends to the predetermined depth to drill the road core sample, and finally the lifting cylinder 54 drives the lifting platform 52 to rise again, and the road core sample from the sampling hole is taken out, completing the road core sampling process.
