Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering foundation testing device. Background Technology

[0002] A foundation refers to the soil or rock mass that supports a building. Soil layers used as building foundations are classified as rock, gravelly soil, sandy soil, silty soil, clayey soil, and artificial fill. Foundations are divided into two categories: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require reinforcement. Artificial foundations require reinforcement treatment, commonly using methods such as stone chip cushion layers, sand cushion layers, and backfilling with a mixture of lime and soil followed by compaction.

[0003] To ensure the stability of water conservancy projects after construction, foundation testing devices are needed to test the foundation. During testing, drilling is required. When the foundation is hard, the drill rod is prone to jamming, making drilling impossible. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a foundation testing device for water conservancy projects. It has the following beneficial effects:

[0015] 1. This foundation testing device for water conservancy projects, through the installation of springs, crossbars, and levers, starts the motor A, which drives the drill rod to rotate via a shaft. The spring pulls the misalignment plate into contact with the movable plate, causing the inner rib sleeve to fit onto the outer surface of the outer rib sleeve. The shaft, via a conveyor belt, rotates the inner rib sleeve, which then drives the threaded outer sleeve to mesh with the threaded rod. When the drill rod cannot drill through hard foundations in time, the movable plate and misalignment plate move away from each other, causing the inner and outer rib sleeves to gradually separate. At this time, the motor B, through the horizontal shaft, drives the lever to rotate, which in turn moves the crossbar. The crossbar then moves the misalignment plate upwards, quickly moving it away from the movable plate. As the drill rod moves upwards, it strikes the hard foundation, increasing drilling efficiency and preventing the drill rod from jamming. This solves the problem of drill rod jamming when drilling through hard foundations, thus hindering drilling.

[0016] 2. The foundation testing device for this water conservancy project, by setting a lower groove and an upper groove, in the initial state, the spring pulls the misaligned plate to contact the movable plate, and the upper groove and lower groove store the spring to prevent the misaligned plate and the movable plate from crushing the spring.

The outer surface of the outer prism sleeve 7 and the outer surface of the inner prism sleeve 9 are both multi-faceted structures. The outer prism sleeve 7 and the threaded rod 4 are coaxially arranged. When the inner prism sleeve 9 rotates, it will drive the outer prism sleeve 7 to rotate.

[0024] A shaft 10 is rotatably passed through the upper surface of the misaligned plate 8. A motor A11 is installed above the shaft 10. The upper end of the shaft 10 is fixedly connected to the output end of the motor A11. A connecting frame 12 is fixedly sleeved on the outer surface of the motor A11. The motor A11 can drive the shaft 10 to rotate in both directions. The bottom surface of the connecting frame 12 is fixedly connected to the upper surface of the misaligned plate 8. The shaft 10 and the inner rib sleeve 9 are driven by a conveyor belt 13, which is located above the misaligned plate 8.

[0025] A drill rod 14 is fixedly connected to the lower end of the shaft 10. The drill rod 14 is coaxial with the shaft 10. Two vertical rods 3 are symmetrically distributed about the axis of the drill rod 14. The drill rod 14 is located below the two vertical rods 3. A threaded rod 4 is parallel to the two vertical rods 3 and parallel to the drill rod 14. The threaded rod 4 and the two vertical rods 3 are distributed in an isosceles triangle. Two side plates 15 are fixedly connected to the front of the movable plate 5. A crossbar 17 is fixedly connected to the front end of the connecting frame 12. A horizontal shaft 16 is set above the front of the crossbar 17. The two side plates 15 are rotatably sleeved. At the left and right ends of the horizontal axis 16, three levers 18 are fixedly connected to the outer surface of the horizontal axis 16. When the inner prism sleeve 9 is engaged with the outer prism sleeve 7, the lever 18 will not push the horizontal bar 17 when it rotates. When the inner prism sleeve 9 is disengaged from the outer prism sleeve 7, the lever 18 can push the horizontal bar 17 upward when it rotates.

A motor B20 is fixedly connected to the left side of the side plate 15 located on the left side. The output end of the motor B20 is fixedly connected to the left end of the horizontal shaft 16.

[0027] Working principle: In the initial state, the threaded outer sleeve 6 is located at the upper end of the threaded rod 4. The support plate 1, controlled by the hanger 2, moves the drill rod 14 above the foundation. The motor A11 is started, which drives the drill rod 14 to rotate via the shaft 10. The spring 19 pulls the misalignment plate 8 to contact the movable plate 5, so that the inner rib sleeve 9 is fitted onto the outer surface of the outer rib sleeve 7. The shaft 10 drives the inner rib sleeve 9 to rotate via the conveyor belt 13. Then, the outer rib sleeve 7 drives the threaded outer sleeve 6 to mesh with the threaded rod 4, causing the movable plate 5 to move downward relative to the support plate 1, thus driving the drill rod 14 to drill into the foundation. When the drill rod 14 cannot drill through the hard foundation in time, the movable plate 5 and the misalignment plate 8 move away from each other, causing the inner sleeve 9 and the outer sleeve 7 to gradually separate. At this time, when the motor B20 drives the lever 18 to rotate through the horizontal shaft 16, it can move the horizontal bar 17. The horizontal bar 17 drives the misalignment plate 8 to move away from the movable plate 5 quickly. After the lever 18 and the horizontal bar 17 separate, the misalignment plate 8 moves closer to the movable plate 5 under the pull of the spring 19, causing the drill rod 14 to move upward and strike the hard foundation, increasing the drilling efficiency and preventing the drill rod from getting stuck.
