Abstract
Description
Technical Field
[0001] This utility model relates to the field of road inspection, and in particular to a vehicle-mounted core drilling device. Background Technology
[0002] In pavement structure design, each structural layer plays a crucial role in the overall pavement stability. According to relevant statistics, many roads currently exhibit widespread damage such as potholes and cracks before reaching their designed service life. These damages mostly stem from insufficient thickness of the pavement structural layers or other structural defects, leading to a significant decrease in the pavement's load-bearing capacity. Furthermore, the appearance of these damages substantially increases subsequent maintenance and repair costs, resulting in resource waste and reduced traffic efficiency.
[0003] To effectively prevent the occurrence of the aforementioned defects and reduce unnecessary maintenance costs, standardized testing and evaluation of the construction quality of pavement structural layers are urgently needed in road engineering. Among existing technologies, core drilling is a widely used traditional testing method. This method involves drilling and analyzing pavement core samples to directly determine whether the thickness of each structural layer meets the specifications and whether there are hidden dangers such as voids or inclusions in the structural layers. Core drilling is typically performed using a concrete core drilling machine, which mainly consists of the drilling rig itself (driven by diesel or gasoline) and a core barrel.
[0004] However, most of the core drilling machines currently used by road inspection units are commercially available complete machines. These machines are bulky and large in size. In actual inspection operations, they are inconvenient to transport, or even after being transported by vehicle, they still need to be manually carried to the designated location, which reduces the efficiency of core drilling operations. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, where most of the core drilling machines used by road inspection units are commercially available complete machines. These machines are bulky and large in size, making them inconvenient to transport during actual inspection operations. Furthermore, even after being transported by vehicle, they still require manual handling to reach the designated location, thus reducing the efficiency of core drilling operations. This invention provides a vehicle-mounted core drilling device.
[0006] In a first aspect, the present invention provides a vehicle-mounted drilling and coring device, including a carrier, a carrying platform on the carrier, a coring structure slidably disposed on the upper end of the carrying platform, an extension frame hinged to one end of the carrying platform, the extension frame including a folded posture perpendicular to the carrying platform, and an unfolded posture coplanar with the carrying platform.
[0007] The core-taking structure is equipped with a walking system at its bottom, and the extension frame and the supporting platform are equipped with guide rails that cooperate with the walking system. The guide rails can be used to limit the walking path of the core-taking structure.
[0008] This invention provides a vehicle-mounted core drilling device. By installing a carrying platform and an extension frame hinged to the carrying platform on a vehicle, the extension frame can be extended and folded relative to the carrying platform. A core-taking structure is mounted on the carrying platform, and a walking system is located below the core-taking structure. Guide rails that cooperate with the walking system are provided on both the carrying platform and the extension frame, allowing the core-taking structure to move along the guide rails on the carrying platform and the extension frame. This enables the core-taking structure to quickly extend and retract from the vehicle body to the detection point according to operational needs, significantly improving equipment deployment efficiency, reducing manual handling, and lowering workload. Compared to traditional core drilling machines that require manual handling, this invention allows the core-taking structure to move directly above the work position after the extension frame is extended, thus improving the efficiency of core drilling operations.
[0009] Preferably, the bottom of the bearing platform is fixedly connected to the carrier, and the bearing platform is provided with first hydraulic cylinders on both sides, with one end of the first hydraulic cylinder hinged to the bearing platform and the other end hinged to the extension frame.
[0010] The extension frame's unfolding and folding are achieved through the extension and retraction of the first hydraulic cylinder, enabling active control of its posture. When the first hydraulic cylinder extends, it pushes the extension frame to flip outward from its folded state, ultimately achieving an unfolded posture coplanar with the support platform. When the first hydraulic cylinder retracts, it drives the extension frame to fold back to the side of the support platform, completing the switch to the equipment's stowage state. This structural design simplifies the manual deployment process and improves the deployment efficiency and operational safety of the device.
[0011] Preferably, the extension frame is provided with a telescopic foot at the end away from the support platform, the telescopic foot is arranged perpendicular to the extension frame, and the end of the telescopic foot away from the extension frame is provided with a roller.
[0012] When the extension frame is deployed, it contacts the ground through telescopic feet, which provides support for the extension frame and improves its structural strength. The rollers allow for fine-tuning of the core structure by activating the carrier if there is a deviation between the core structure and the working position.
[0013] Preferably, the core extraction structure includes a support frame, the bottom of which is connected to the walking system, and a vertical lifting channel is provided in the middle of the support frame. A lifting platform is provided in the lifting channel, and the lifting platform can move up and down within the lifting channel.
[0014] The lifting platform is equipped with a core drilling machine.
[0015] The structural stability of the coring device is ensured by setting up a support frame, and a lifting channel is set in the middle of the support frame. A lifting platform is also set in the lifting channel so that the lifting platform can move along the lifting channel. The lifting platform is equipped with a core drilling machine. After the coring structure reaches the working position, the core drilling machine can be lowered by the lifting platform so that it can be closer to the ground at the working position.
[0016] Preferably, the supporting frame is provided with a fixed beam, and a second hydraulic cylinder is provided below the fixed beam. One end of the second hydraulic cylinder is connected to the fixed beam, and the other end is connected to the lifting platform.
[0017] Preferably, the lifting platform is also symmetrically provided with a plurality of sliding columns, and the lifting platform is connected to the side wall of the lifting channel through the sliding columns.
[0018] Preferably, the sliding column includes a guide cylinder, the outer wall of which is connected to the side wall of the lifting channel. The sliding column also includes a third hydraulic cylinder, one end of which is connected to the top of the lifting platform and the other end of which passes through the guide cylinder.
[0019] The sliding column, consisting of several guide tubes and a third hydraulic cylinder, guides the third hydraulic cylinder during the movement of the lifting platform. This reduces the displacement caused by vibration during the movement of the lifting platform and improves the stability of the structure.
[0020] Preferably, the core drilling machine includes a drill bit, and the lifting platform is provided with a vertical through hole, which allows the drill bit to pass through the lifting platform.
[0021] Preferably, the vehicle-mounted core drilling device further includes a control device, which includes a generator connected to both the core drilling machine and the walking system.
[0022] Preferably, the control device further includes an oil supply device, which is connected to the generator via an oil supply pipe, and the oil supply device is also connected to an operating console.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0024] 1. This utility model provides a vehicle-mounted core drilling device. By installing a carrying platform and an extension frame hinged to the carrying platform on a vehicle, the extension frame can be unfolded and folded relative to the carrying platform. A core-taking structure is set on the carrying platform, and a walking system is provided below the core-taking structure. Both the carrying platform and the extension frame are equipped with guide rails that cooperate with the walking system, so that the core-taking structure can move along the guide rails on the carrying platform and the extension frame. It can quickly extend and retract the core-taking structure from the vehicle body to the detection point according to the operation requirements, which significantly improves the equipment deployment efficiency, reduces manual handling, and reduces the labor intensity. Compared with the traditional method of manually moving the core drilling machine, this utility model allows the core-taking structure to move on the extension frame after it is unfolded, so that the core-taking structure can be directly positioned above the working position and start the core-taking operation, which improves the efficiency of the core-taking operation.

The extension and retraction of the first hydraulic cylinder 6 realizes the unfolding and folding of the extension frame 4, achieving active control of the posture of the extension frame 4.

When the first hydraulic cylinder 6 retracts, it drives the extension frame 4 to fold back to the side of the support platform 2, completing the switching of the device's storage state. The structural design simplifies the manual deployment process and improves the deployment efficiency and operational safety of the device. Both the support platform 2 and the extension frame 4 are equipped with guide rails 5.
