Description

Technical Field

[0001] This utility model belongs to the field of core retrieval machine support technology, specifically relating to a mobile support structure used in conjunction with a vehicle-mounted core retrieval machine. Background Technology

[0002] In pavement structure design, each structural layer plays a crucial role in the overall stability of the pavement. According to relevant statistics, many pavements develop extensive potholes, cracks, and other defects before reaching their intended service life. A significant portion of these defects are caused by substandard thickness of the pavement structural layers or other structural flaws. These defects not only drastically reduce the pavement's load-bearing capacity but also significantly increase the cost of subsequent maintenance and repair. Therefore, to avoid these defects and unnecessary maintenance costs, the pavement structural layers should undergo standardized quality testing and evaluation during pavement engineering inspections.

[0003] In traditional pavement inspection techniques, core drilling is a commonly used method. By analyzing the drilled core samples, it is possible to directly detect whether the thickness of each structural layer of the pavement meets the standards and whether there are other pavement structural defects. The testing equipment used in core drilling is a concrete core drill, which consists of a diesel or gasoline-powered drill and a core cylinder. Currently, road engineering inspection units mainly purchase concrete core drills from manufacturers. The core drill itself is quite heavy, requiring at least four people to carry it back and forth from the vehicle during highway core sampling operations, making the operation time-consuming and labor-intensive. Furthermore, the existing mobile support frames used with vehicle-mounted core drills have the following problems in use:

[0004] 1. When adjusting the position of the core extractor horizontally or vertically, there may be offset or jamming, which makes it time-consuming and laborious to adjust the core extractor to the required position.

[0005] Second, the horizontally supported track has poor stability when supported, which will cause shaking when the core reamer is working, resulting in poor stability of the core reamer during operation. Utility Model Content

[0047] like Figure 1As shown, in this specific embodiment, the longitudinal position adjustment of the core-retrieving mechanism 6 is driven by the movable longitudinal sliding frame 4. The specific technical solution is as follows: it includes a movable longitudinal sliding frame 4 and a core-retrieving machine 6; the movable longitudinal sliding frame 4 is installed on the front side of the upper end face of the movable transverse sliding frame 2, and the core-retrieving machine 6 is installed on the upper end face of the movable longitudinal sliding frame 4, as shown...

[0048] The working principle of this specific embodiment is as follows: In use, the fixed sliding frame 1 is installed on the vehicle. When the core extractor 6 is needed, the movable transverse sliding frame 2 is adjusted first. The movable transverse sliding frame 2 is supported by the adjusting support mechanism 5. When adjusting the support mechanism 5, the adjusting screw 5-2 is rotated by turning the lever 5-3, so that the supporting base plate 5-4 is supported on the ground. At this time, the supporting ball bearing 5-5 will contact the ground. When the movable track 2-1 moves outward, the supporting pulley 1-2 can support the movable track 2-1. The movable wheel 2-2 can slide within the sliding groove 1-11, while the T-shaped slider 3-2 moves within the T-shaped limiting groove 1-12, making it difficult for the movable transverse sliding frame 2 to derail. After the transverse position is adjusted, the T-shaped slider 3-2 is locked by the locking bolt 3-3. Then, the longitudinal position is adjusted by the movable longitudinal sliding frame 4. During adjustment, the sliding seat 4-2 moves within the movable groove 4-11 of the longitudinal track 4-1, which can realize the adjustment of the longitudinal position of the core extractor 6, facilitating rapid control and adjustment.
