Technical Field

[0001] This invention relates to the field of static cone penetration testing technology. More specifically, this invention relates to an inclined static cone penetration testing device. Background Technology

[0002] As cities develop, urban space becomes increasingly limited and various buildings become densely packed. The use of inclined static cone penetration testing can solve many problems related to insufficient site space.

[0003] Compared to conventional vertical exploration trajectories, inclined borehole exploration allows drilling at appropriate angles outside the target area to ascertain the geological conditions within a certain range underground in the target region. This enables exploration operations to be completed under harsh natural environments, effectively improving the accuracy and relevance of exploration results.

[0004] Therefore, there is an urgent need for a modular inclined static cone penetration test device that is structurally sound, easy to operate, and provides reliable data. Summary of the Invention

[0005] The purpose of this invention is to provide an inclined static penetration test device that is structurally stable, angle adjustable, has high penetration efficiency, and accurate data correction.

[0006] To achieve these objectives and other advantages according to the present invention, an inclined static cone penetrometer is provided, comprising:

[0007] Static cone penetrometer;

[0009] A rotating support is rotatably mounted on the anchor seat, and the static cone penetrometer is detachably mounted on the rotating support.

[0010] An angle adjustment mechanism is provided on the anchor seat and drivenly connected to the rotating support to adjust the angle between the rotating support and the anchor seat.

[0011] Furthermore, in the aforementioned inclined static cone penetration test device, the anchor base includes:

The distance between the two anchor plates in the second direction is adjustable and they are connected and fixed by at least two tie rods. The rotating support is rotatably connected to the two anchor plates respectively.

[0016] Two telescopic cylinders are provided. The upper end of the anchoring seat is provided with a first through groove along a first direction. A round shaft is provided in the first through groove along a second direction. One end of the rotating plate is provided with a protrusion. The protrusion is hinged to the round shaft. The telescopic cylinder is set in the first through groove. A rotating seat is fixedly provided in the first through groove. A connecting piece is provided at the lower end of the rotating plate. The cylinder body end of the telescopic cylinder is hinged to the rotating seat. The end of its push rod is hinged to the connecting piece.

[0017] Two telescopic rods are provided. The lower end of the rotating plate and the first through groove are both provided with hinge seats. The telescopic rod is provided between the two hinge seats. The two ends of the telescopic rod are detachably connected to the two hinge seats respectively.

[0018] Furthermore, in the aforementioned inclined static cone penetration test device, the anchor base is made of channel steel.

[0019] Furthermore, in the aforementioned inclined static cone penetration device, the lower end of the rotating plate is provided with a second through groove corresponding to the anchor seat.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application, so that those skilled in the art can implement them based on the description. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0041] In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0043] like Figures 1-3 As shown, an embodiment of the present invention provides an inclined static cone penetrometer, comprising:

[0044] Static cone penetrometer;

[0045] An anchoring base, with an opening in the middle for the probe rod of the static cone penetrometer to pass through;

[0046] A rotating support is rotatably mounted on the anchor seat, and the static cone penetrometer is detachably mounted on the rotating support.

[0047] An angle adjustment mechanism is provided on the anchor seat and drivenly connected to the rotating support to adjust the angle between the rotating support and the anchor seat.

[0048] In this embodiment, multiple anchor holes are set on the anchor seat, and helical anchors are installed in the anchor holes and driven into the ground. The frictional resistance and interlocking force between the helical anchors and the surrounding soil provide the reaction force to fix the anchor seat to the ground. After the anchor seat is installed, its upper end is ensured to be horizontal, and then the static cone penetrometer is fixed on the rotating support. In the initial state, the angle between the rotating support and the anchor seat is zero, so that the lower end of the static cone penetrometer is horizontal and the drill rod of the static cone penetrometer is in a vertical state. In actual use, one end of the rotating support in the first direction is hinged to the anchor seat. When it is necessary to adjust the angle of the drill rod of the static cone penetrometer, the rotating support is driven to rotate around one end through the angle adjustment mechanism, so that the rotating support can rotate in the vertical plane in the first direction. Adjusting the angle between the rotating support and the anchor seat, the angle of the drill rod of the static cone penetrometer is adjusted. After the static cone penetrometer starts working, its probe rod passes downward through the opening in the middle of the anchor seat and drills into the ground.

[0049] Preferably, as another embodiment of the present invention, such as Figure 2 As shown, the anchorage includes:

[0050] Two anchor plates 1, made of channel steel, are horizontally arranged along a first direction and opposite each other along a second direction perpendicular to the first direction. The distance between the two anchor plates 1 in the second direction is adjustable and they are connected and fixed by at least two tie rods 2. The rotating support is rotatably connected to the two anchor plates 1 respectively.

[0051] In this embodiment, the distance between the two anchor plates 1 is adjustable, allowing the distance to be changed according to different usage scenarios, thus reducing the footprint required for the anchoring base in confined spaces. The two anchor plates 1 are connected by tie rods 2, which are easy to install and remove, facilitating the adjustment of the distance between the two anchor plates 1.

[0052] Preferably, as another embodiment of the present invention, such as Figure 2 As shown, the rotating support includes:

[0053] Two rotating plates 3 are rotatably mounted on the two anchor plates 1 and connected to the angle adjustment mechanism. The upper end of the rotating plate 3 is provided with a connecting component and is detachably connected to the static penetrometer shown through the connecting component.

[0054] In this embodiment, the two rotating plates 3 together form a rotating support, and the upper ends of the two rotating plates 3 form a mounting part. The two rotating plates 3 are rotatably mounted on the two anchor plates 1, so that when the distance between the two anchor plates 1 is adjusted, the distance between the two rotating plates 3 can also be adjusted accordingly.

[0055] To match the structure of the anchorage and swivel bearing, the angle adjustment mechanism includes:

[0056] Two telescopic cylinders 4 are provided. The upper end of the anchor seat is provided with a first through groove 5 along the first direction. A round shaft 6 is provided in the first through groove 5 along the second direction. One end of the rotating plate 3 is provided with a protrusion 7. The protrusion 7 is hinged to the round shaft 6. The telescopic cylinder 4 is set in the first through groove 5. A rotating seat 8 is fixedly provided in the first through groove 5. A connecting piece 9 is provided at the lower end of the rotating plate 3. The cylinder body end of the telescopic cylinder 4 is hinged to the rotating seat 8, and the end of its push rod is hinged to the connecting piece 9.

[0057] Two telescopic rods 18 are provided. The lower end of the rotating plate 3 and the first through groove 5 are both provided with hinge seats 19. The telescopic rods 18 are provided between the two hinge seats 19. The two ends of the telescopic rods 18 are detachably connected to the two hinge seats 19 respectively.

[0058] By setting a protrusion 7 at one end of the rotating plate 3, the protrusion 7 is located in the first through groove 5, so that when the rotating plate 3 rotates, one end of the rotating plate 3 does not contact the upper end of the anchor plate 1, thus ensuring the stable rotation of the rotating plate 3.

[0059] like Figure 4 As shown, in the initial state, the angle between the rotating support and the anchor seat is zero. At this time, the push rod of the telescopic cylinder 4 is fully retracted into the cylinder body, and the rotating plate 3 rests on the upper end of the corresponding anchor plate 1. When the push rod of the telescopic cylinder 4 is pushed outward, as... Figure 5 As shown, the push rod drives the rotating plate 3 to rotate around the protrusion 7 at its lower end. Therefore, by controlling the extension length of the push rod of the telescopic cylinder 4, the angle between the anchor plates 1 and the rotating plate 3 can be adjusted. The rotating plate 3 can rotate 0-90° relative to the anchor plates 1. The two telescopic cylinders 4 work synchronously to ensure that the two rotating plates 3 always remain parallel, thus forming the mounting section.

[0060] To reduce the pressure of the rotating support on the telescopic cylinder 4, a telescopic rod 18 is installed between the rotating support and the anchorage. The telescopic rod 18 supports the rotating support and shares the pressure on the telescopic cylinder 4. Specifically, in the initial state, the telescopic rod 18 is not installed inside the anchorage, such as... Figure 4 As shown. After the telescopic cylinder 4 lifts the rotating support, the lower end of the telescopic rod 18 is connected to the hinge seat 19 in the first through groove 5. Then, the length of the telescopic rod 18 is adjusted to fit, and the upper end of the telescopic rod 18 is connected to the hinge seat 19 at the lower end of the rotating support. Figure 5 As shown, the rotating support is supported by the telescopic rod 18, which shares the pressure of the rotating support on the telescopic cylinder 4.

[0061] Preferably, in another embodiment of the present invention, the lower end of the rotating plate 3 is provided with a second through groove corresponding to the anchor seat. When the push rod of the telescopic cylinder 4 is fully retracted into the cylinder body, the anchor seat extends into the corresponding second through groove and abuts against the rotating plate 3.

[0062] In this embodiment, the rotating plate 3 can also be a channel steel support with its opening facing downwards.

[0063] Preferably, in another embodiment of the present invention, the static cone penetrometer includes:

[0064] Penetration device 10;

[0065] The base is located at the lower end of the penetration device 10, and the base is detachably connected to the two rotating plates 3.

[0066] In this embodiment, the penetration device 10 can be made using existing technology, which will not be described in detail here. Its lower end, the base, includes two support rods 13 horizontally arranged along the second direction.

[0067] Preferably, in another embodiment of the present invention, the connecting component includes:

[0068] Positioning component 11, the upper end of the rotating plate 3 is provided with positioning components 11 on both sides, the positioning component 11 is provided with a third through groove 12 along the second direction, the base includes two support rods 13 arranged horizontally along the second direction, the two ends of the support rods 13 are respectively embedded in one of the third through grooves 12 of the two rotating plates 3;

[0069] The positioning bolt 14 has first mounting holes on both sides of the third through groove 12, and second mounting holes 15 on both ends of the support rod 13. The two first mounting holes and the second mounting holes 15 form an installation channel. The positioning bolt 14 passes through the installation channel and is threaded with a nut.

[0070] In this embodiment, such as Figure 4 and Figure 5 As shown, two positioning elements 11 are spaced apart along the second direction on the upper end of the rotating plate 3. The positioning element 11 can be made of two plates, the lower end of which is welded to the rotating plate 3. A third through groove 12 is formed between the two plates. The support rod 13 of the base can be embedded in the third through groove 12. The support rod 13 and the positioning element 11 are connected and fixed by the positioning bolt 14 passing through the support rod 13 and the positioning element 11 and tightening the nut, thereby realizing the installation and fixation of the static penetrometer on the rotating support.

[0071] Preferably, in another embodiment of the present invention, both ends of the support rod 13 are provided with a plurality of second mounting holes 15 evenly distributed along its length direction.

[0072] In this embodiment, multiple second mounting holes 15 are evenly distributed at both ends of the support rod 13 along its length direction, so that when adjusting the distance between the two anchor plates 1, the positioning member 11 can be connected to different positions of the support rod 13.

[0073] Preferably, in another embodiment of the present invention, a level 16 is provided at the upper end of the anchoring base, and a digital display inclinometer 17 is provided on the rotating support.

[0074] In this embodiment, a level 16 is installed on the anchor base. Levels 16 can be installed on both anchor plates 1 to ensure the upper end of the anchor base is horizontal. Simultaneously, a digital inclinometer 17 is installed on the rotating support. The angle between the rotating plate 3 and the anchor plate 1 can be quickly obtained using the digital inclinometer 17, thus providing the real-time angle of the drill rod of the static cone penetrometer.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application, and should all be covered within the scope of the claims of this application.
