Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling devices, in particular to a soil sampling device for engineering testing. Background Art

[0002] In order to ensure the safety of construction projects that have been built, are under construction, and will be built, it is an important task to test the foundations, building materials, construction technology, and building structures related to the buildings throughout the construction process. Soil sampling is one of the effective ways to understand the nature of the foundation. There are many types of soil sampling equipment, including a gasoline-powered soil sampler. The gasoline-powered soil sampler is driven by gasoline or diesel. The gasoline-powered hammer impacts the stainless steel drill bit, so that the stainless steel drill bit can be easily inserted into the deep soil for soil sampling. Compared with the bulky hydraulic and pneumatic soil drilling rigs, the gasoline-powered soil sampler has the characteristics of light weight, low fuel consumption, high power, stable performance, and long life.

[0003] When using a gasoline-powered soil sampler to sample soil, there are generally two modes. One is to first connect the drill rod, drill bit and gasoline-powered hammer, and then stand the device upright to sample the soil. The gasoline-powered hammer, the drill rod and the drill bit are relatively high in height, and the gasoline-powered hammer has a relatively heavy weight. Therefore, when sampling is performed after the drill rod, drill bit and gasoline-powered hammer are installed, it is not easy to align the drill bit with the sampling point.

[0004] The second mode is to first connect the drill rod and the drill bit, then place the drill rod and the drill bit vertically, align the drill bit with the sampling point, and then transfer the gasoline-powered hammer to the top of the drill rod to impact the drill rod. The advantage of this operation is that it can achieve precise alignment of the drill bit and the sampling point, but during operation, one person is required to continue to support the drill rod to keep it upright, and the cooperation of more sampling personnel is required to complete it. The sampling operation is subject to certain restrictions. Based on this, a soil sampling device for engineering testing is provided. Utility Model Content

[0030] See also Figures 1 to 4 In the embodiment of the utility model, an engineering soil sampling device includes a gasoline powered hammer 1 and a drill rod 2. An auxiliary support assembly 3 is provided on the outside of the drill rod 2. The auxiliary support assembly 3 is used to provide auxiliary support for the upright state of the drill rod 2.

[0031] The auxiliary support assembly 3 includes a support unit, a storage unit, and a locking unit;

[0032] The support unit in the unfolded state is used to wrap and limit the drill rod 2, so that the drill rod 2 can be placed upright;

[0033] The storage unit is used to realize the storage and deployment of the support unit;

[0034] The locking unit is used to lock the storage state and the unfolded state of the support unit;

[0035] The supporting unit includes a first C-shaped seat 301, a second C-shaped seat 302, a third C-shaped seat 303, a first connecting seat 304, a second connecting seat 305, a third connecting seat 306, and a supporting rod 307;

[0036] The first C-shaped seat 301 and the second C-shaped seat 302 are distributed in the vertical direction and aligned with each other. The second C-shaped seat 302 is slidably connected in the middle of the first C-shaped seat 301 and the second C-shaped seat 302. When the second C-shaped seat 302 is aligned with the first C-shaped seat 301 and the second C-shaped seat 302, it can be attached to the outside of the drill rod 2 through its opening. When the second C-shaped seat 302 is misaligned with the first C-shaped seat 301 and the second C-shaped seat 302, the second C-shaped seat 302 fills the gap of the first C-shaped seat 301 and the second C-shaped seat 302, so as to achieve all-round wrapping of the drill rod 2.

[0037] The first connection seat 304 is fixed to one side of the outer wall of the first C-shaped seat 301 and the second C-shaped seat 302, the second connection seat 305 is fixed to the other side connected to the second C-shaped seat 302 and is symmetrically distributed with the first connection seat 304, and the third connection seat 306 is fixed to one side of the outer wall of the third C-shaped seat 303. When the first C-shaped seat 301, the second C-shaped seat 302 and the third C-shaped seat 303 are aligned, the third connection seat 306 is located between the first connection seat 304 and the second connection seat 305;

[0038] The support rod 307 is rotatably connected to the first connection seat 304, the second connection seat 305, and the third connection seat 306, and the three support rods 307 are unfolded into a tripod structure to realize auxiliary support for the drill rod 2;

[0039] The storage unit includes an arc-shaped rail groove 308 and an arc-shaped limiting slider 309;

[0040] The arc-shaped rail groove 308 is opened at the top of the first C-shaped seat 301 and the second C-shaped seat 302 and passes through the bottom of the first C-shaped seat 301 and the second C-shaped seat 302;

[0041] The arc-shaped limiting slider 309 is fixed to one end of the third C-shaped seat 303 and protrudes from the upper and lower ends of the third C-shaped seat 303. The arc-shaped limiting slider 309 is slidably connected to the inner side of the arc-shaped rail groove 308. The third C-shaped seat 303 can be unfolded and stored by the arc-shaped limiting slider 309 moving along the track of the arc-shaped rail groove 308.

[0042] The locking unit includes a locking hole 310 and a T-shaped locking rod 311;

[0043] The locking hole 310 is opened at the other end of the third C-shaped seat 303 and passes through the upper and lower ends of the third C-shaped seat 303. The T-shaped locking rod 311 passes through the arc-shaped rail groove 308, the locking hole 310 and the bottom of the second C-shaped seat 302 from the top of the first C-shaped seat 301 in sequence, so as to realize the locking of the third C-shaped seat 303 in the unfolded and stored states.

[0044] The inner wall diameters of the first C-shaped seat 301 , the second C-shaped seat 302 , and the third C-shaped seat 303 match the outer wall diameter of the drill rod 2 , and the height of the third C-shaped seat 303 matches the height between the first C-shaped seat 301 and the second C-shaped seat 302 .

[0045] In this embodiment, when soil sampling is required, the auxiliary support assembly 3 can be sleeved with the outer side of the drill rod 2, and the operation steps are as follows:

[0046] In the initial state of the auxiliary support assembly 3, the third C-shaped seat 303 thereof is aligned with the first C-shaped seat 301 and the second C-shaped seat 302. At this time, the notches of the first C-shaped seat 301, the second C-shaped seat 302 and the third C-shaped seat 303 are aligned with the outer wall of the drill rod 2 to be clamped so that they fit with one side of the outer wall of the drill rod 2. Then, the third C-shaped seat 303 is rotated so that the third C-shaped seat 303 moves along the trajectory of the arc-shaped track groove 308. The third C-shaped seat 303 is finally misaligned with the first C-shaped seat 301 and the second C-shaped seat 302. At this time, the third C-shaped seat 303 fits with the other side of the drill rod 2. At this time, the third C-shaped seat 303 and the first C-shaped seat 301 and the second C-shaped seat 302 form an annular structure as a whole to completely wrap the drill rod 2.

[0047] During the above operation, when the third C-shaped seat 303 is rotated, the support rod 307 rotatably connected to the third connecting seat 306 needs to be rotated upward so that the support rod 307 will not interfere with the second connecting seat 305 during the movement.

[0048] When the third C-shaped seat 303 is moved, its arc-shaped limit slider 309 is located at one end of the arc-shaped rail groove 308, and the locking hole 310 on the third C-shaped seat 303 is aligned with the other end of the arc-shaped rail groove 308. At this time, the T-shaped locking rod 311 is sequentially passed through the arc-shaped rail groove 308 and the locking hole 310 from the top of the first C-shaped seat 301 and then passed through the bottom of the second C-shaped seat 302, and then the third C-shaped seat 303 is fixed at this position;

[0049] After the support auxiliary assembly 2 is connected to the drill rod 2, it is transferred as a whole to the sampling point, and the drill rod 2 is aligned with the sampling point (it should be noted that the drill rod 2 is equipped with a drill bit), and then the three support rods 307 are unfolded to form a tripod structure to support the drill rod 2 in a vertical state, and then the support for the drill rod 2 can be released, and then the gasoline-powered hammer 1 is taken over and aligned with the top of the drill rod 2 for impact and sampling operations;

[0050] It should be noted that after the drill rod 2 is drilled into the soil, the support auxiliary component 2 can be removed. You only need to remove the T-shaped locking rod 311 and move the third C-shaped seat 303 back to its initial state to achieve disassembly of the support auxiliary component 2. The operation is simple and convenient. After the third C-shaped seat 303 is completely aligned with the first C-shaped seat 301 and the second C-shaped seat 302, the T-shaped locking rod 311 can be inserted into the locking hole 310 again to lock the third C-shaped seat 303 in the storage state.

[0051] Please refer to Figures 1 to 4 The top view cross-section of the arc-shaped limit slider 309, the locking hole 310 and the contact portion between the T-shaped locking rod 311 and the locking hole 310 is arc-shaped, and the inner and outer diameters of the arc-shaped cross-section match the inner and outer diameters of the inner wall of the arc-shaped rail groove 308.

[0052] In this embodiment: through this structure, the arc-shaped limit slider 309 can only move along the trajectory of the arc-shaped rail groove 308 and cannot rotate, so that the trajectory of the third C-shaped seat 303 during the storage and expansion process remains stable. In this way, during the storage process, the locking hole 310 and the arc-shaped rail groove 308 can remain aligned, and the insertion operation of the T-shaped locking rod 311 is more convenient. At the same time, by inserting the T-shaped locking rod 311 into the arc-shaped rail groove 308 and the locking hole 310, the third C-shaped seat 303 can be firmly fixed.

[0053] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
