Description

Technical Field

[0001] This utility model relates to the field of probing machine technology, and in particular to a probing machine for testing building foundations. Background Technology

[0002] Currently, to gain access to the interior of building foundations and obtain detailed information about their condition, such as soil compaction, strength, and potential defects or voids, probing machines are used. This information is unavailable through surface inspection, making them crucial for assessing foundation health. In existing technologies, when the foundation soil at a construction site is not adequately compacted or treated, areas on the soil surface may be too loose or too hard. Placing a probing machine on this soil can lead to uneven stress distribution, causing instability, tilting, or collapse. Therefore, current probing machines typically use multiple cylinders at the bottom to stabilize the ground. However, uneven ground or uneven support points (e.g., some cylinders bearing excessive stress) can overload certain cylinders, exceeding their operating capacity, causing stress release, and ultimately leading to tilting or collapse. Utility Model Content

[0003] The purpose of this invention is to address the problem that current probing machines typically have multiple cylinders at the bottom to hold the ground stable on the soil, but the ground supported by these cylinders is uneven or the support points are uneven (for example, some cylinders are subjected to greater force), which leads to stress loss and ultimately causes the equipment to tilt or collapse. This invention proposes a probing machine for building foundation testing.

[0004] The technical solution of this utility model is as follows: a probing machine for building foundation testing, including a probing machine body and a base frame disposed at the bottom of the probing machine body, and further including: multiple support rod mechanisms fixedly installed at the right-angle ends of the base frame; an anti-reverse mechanism disposed inside the support rod mechanism to prevent it from moving upward; and a calibration mechanism located on the outer wall of the support rod mechanism.

A hydraulic cylinder is fixedly connected to the upper surface of the L-shaped support plate, and a limiting sleeve block is fixedly connected to the lower surface of the L-shaped support plate. A support rod is fixedly connected to the piston rod of the hydraulic cylinder. A limiting groove is provided inside the limiting sleeve block for the support rod to move through. A conical abutment block that abuts against the ground is fixedly connected to the bottom end of the support rod.

[0006] Optionally, the anti-reverse mechanism includes multiple linearly arranged toothed grooves on the support rod, a telescopic groove is provided inside the limiting slide groove, a telescopic block is slidably connected inside the telescopic groove, a protrusion is fixedly connected to the side of the telescopic block near the support rod, which restricts the upward movement of the support rod after being engaged in the toothed groove, a return spring is fixedly connected inside the telescopic groove, and the end of the return spring away from the telescopic groove is fixedly connected to the telescopic block.

[0007] Optionally, the anti-reverse mechanism further includes a pull rod movably connected within the limiting sleeve block, one end of the pull rod movably passing through the telescopic groove and being fixedly connected to the telescopic block, and the other end of the pull rod being fixedly connected to a pull block.

[0008] Optionally, the outer wall of the pull block is provided with a plurality of anti-slip grooves arranged in a circumferential array.

[0009] Optionally, the calibration mechanism includes a level fixedly connected to the outer wall of the limiting sleeve, the L-shaped support plate is provided with calibration fluid, and the outer wall of the level is provided with multiple scale lines arranged in a linear pattern.

[0010] Optionally, the bottom end of the conical block is provided with a pointed tip that can be inserted into the ground.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0024] Example

[0025] like Figures 1 to 4 As shown, the present invention proposes a probing machine for building foundation testing, including a probing machine body 1 and a base frame 11 disposed at the bottom of the probing machine body 1, and further including: multiple support rod mechanisms fixedly installed at the right-angle ends of the base frame 11; an anti-reverse mechanism disposed inside the support rod mechanism to prevent it from moving upward; and a calibration mechanism located on the outer wall of the support rod mechanism.

[0026] Furthermore, the strut mechanism includes multiple L-shaped support plates 2 fixedly connected to the outer wall of the base frame 11. A hydraulic cylinder 21 is fixedly connected to the upper surface of each L-shaped support plate 2. The hydraulic cylinder 21 is a device that uses hydraulic pressure (i.e., energy transmitted through liquid pressure) to generate mechanical force, and is widely used in various types of machinery and equipment, especially in applications requiring high torque or thrust. A hydraulic cylinder typically consists of a steel housing, piston, piston rod, and hydraulic oil, and is an important actuator in a hydraulic system. A limiting sleeve 3 is fixedly connected to the lower surface of the L-shaped support plate 2. A support rod 22 is fixedly connected to the piston rod of the hydraulic cylinder 21. A limiting groove 31 is provided inside the limiting sleeve 3 for the support rod 22 to move through. A conical abutment 23 is fixedly connected to the bottom end of the support rod 22, which increases the contact area between the support rod 22 and the ground, preventing insufficient support due to a small contact area. The bottom end of the conical block 23 is provided with a pointed tip that can be inserted into the ground. The pointed tip allows the conical block 23 to be inserted into the soil and then provide stable support.

[0027] The anti-reverse mechanism includes multiple linearly arranged toothed grooves 24 on the support rod 22. A telescopic groove 32 is formed inside the limiting slide groove 31. A telescopic block 33 is slidably connected inside the telescopic groove 32. A protrusion 34 is fixedly connected to the side of the telescopic block 33 closest to the support rod 22, which, after engaging with the toothed groove 24, restricts the upward movement of the support rod 22. When the protrusion 34 is pressed downward by the toothed groove 24, it automatically retracts into the telescopic groove 32, but upward movement of the toothed groove 24 is blocked. A return spring 35 is fixedly connected inside the telescopic groove 32, ensuring that the protrusion 34 automatically engages with the toothed groove 24. The return spring 35 is movably sleeved with the pull rod 36. The end of the return spring 35 furthest from the telescopic groove 32 is fixedly connected to the telescopic block 33.

[0028] Secondly, the anti-reverse mechanism also includes a pull rod 36 that is movably connected in the limiting sleeve 3. One end of the pull rod 36 moves through the telescopic groove 32 and is fixedly connected to the telescopic block 33. The other end of the pull rod 36 is fixedly connected to a pull block 37. The outer wall of the pull block 37 is provided with multiple anti-slip grooves 38 arranged in a circumferential array. The anti-slip grooves 38 increase the friction between the hand and the pull block 37, ensuring that the pull block 37 will not slip when manually pinched.

[0029] Furthermore, the calibration mechanism includes a level 4 fixedly connected to the outer wall of the limiting sleeve 3. The L-shaped support plate 2 contains a calibration solution, which is a salt solution that will not turn yellow or deteriorate. The outer wall of the level 4 has multiple linearly arranged scale lines 41. Only when the scale line 41 corresponding to the horizontal surface of the calibration solution in each level 4 is the same, will each right-angle end of the base frame 11 be at the same level, thereby ensuring that the probe machine body 1 will not tilt or tip over due to a shift in the center of gravity during operation.

[0030] In this embodiment, when a probing machine is required for building foundation testing, such as... Figure 1 As shown, the hydraulic cylinders 21 on multiple L-shaped support plates 2 are activated sequentially. The piston rods of the hydraulic cylinders 21 push the corresponding support rods 22 downwards. The support rods 22 drive the corresponding conical blocks 23 to abut against the soil surface and directly insert into the ground to form a stable support. At this time, all hydraulic cylinders 21 are stopped. Then, the calibration fluid in the level 4 on the limit sleeve 3 is checked. According to the height of the calibration fluid aligned with the scale line 41 in the level 4, the hydraulic cylinder 21 above the corresponding level 4 is activated again. The hydraulic cylinder 21 drives the conical blocks 23 to abut against the soil surface and causes the end of the base frame 11 to move upwards, so that all the right-angle ends of the base frame 11 are in the same horizontal position, which is simple and easy to operate. When the piston rod of one of the hydraulic cylinders 21 is subjected to greater force, the support rod 22 slides downwards along the limit groove 31. Then, the toothed groove 24 abuts against the protrusion 34, causing it to automatically retract into the telescopic groove 32. When the support rod 22 moves downward to the designated height, the telescopic block 33, through the elastic thrust of the return spring 35 within the telescopic groove 32, causes the protrusion 34 to engage with the toothed groove 24 at the corresponding height. At this time, the support rod 22 cannot move upward, ensuring that the piston rod of the hydraulic cylinder 21 does not bear excessive support force. When it is necessary to move the conical stop block 23 upward to return to its original position... Figure 2 When in the state shown, simply pull the pull block 37 away from the limit sleeve block 3 and move the anti-slip groove 38. The anti-slip groove 38 can then cause the telescopic block 33 and the protrusion 34 to disengage from the toothed groove 24 on the support rod 22. At this time, the support rod 22 can slide freely in the limit slide groove 31, which is quick and easy to operate.
