Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, in particular to a geotechnical slope displacement detection device. Background Art

[0002] Geotechnical engineering mainly refers to underground construction projects such as slopes, foundation pits and tunnels. Different types of projects use different equipment and tools. When constructing a slope, the slope is mainly a slope surface with a certain slope, which may cause displacement due to external factors, thus causing safety hazards. It needs to be detected through a geotechnical engineering slope displacement detection device.

[0003] The existing patent (announcement number: CN220524826U) discloses a geotechnical engineering slope displacement detection device, including a chassis, a pillar is fixedly connected and welded in the middle of the upper surface of the chassis, a retaining seat is welded on the top of the pillar, and a cross slide is provided on both sides of the front of the retaining seat, and a cross guide rod is inserted inside the cross slide. Through the arrangement of the retaining seat, the cross guide rod, the pad and the L-shaped indicator arrow plate, when in use, the retaining seat is fixed to one side of the slope through the chassis, and then the pad is fixed to the slope. When the slope is displaced, the pad moves together, and then drives the cross guide rod to move to one side. At this time, the L-shaped indicator arrow plate will indicate the displacement distance scale line on the cross guide rod, so that personnel can observe the displacement distance. This device has a low cost and does not require power drive, and can adapt to slopes in different areas.

[0004] The above patented technology drives the pad to move together with the displacement of the slope, and then drives the cross guide rod to move to one side. At this time, the L-shaped indicator arrow plate will indicate the displacement distance scale line on the cross guide rod, so that personnel can observe the displacement distance. However, in actual use, when the inclination angle of the slope decreases, the pad is only affected by its own gravity and the action of the fastening bolts. The pad may be difficult to fit the inclination angle of the slope, resulting in the pad being difficult to move with the slope, and the cross guide rod cannot move, resulting in errors in the displacement detection results. Therefore, a rock slope displacement detection device is proposed. Utility Model Content

The pressure sensor sends a signal to the controller. The controller receives the signal and sends the signal to the control terminal, so that the staff can promptly handle the slope accordingly to avoid safety hazards.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] Please refer to Figure 1-Figure 6 The utility model provides a technical solution: a rock slope displacement detection device, including a base 1 and a pad 9, the top outer surface of the base 1 is fixedly connected with a vertical rod 2, the left and right outer surfaces of the vertical rod 2 are fixedly connected with a horizontal plate 3, the outer surfaces of the two horizontal plates 3 are movably inserted with guide rods 4, the rear outer surfaces of the two horizontal plates 3 are fixedly connected with springs 5, the outer surfaces of the springs 5 ​​away from the horizontal plates 3 are fixedly connected with connecting plates 6, the outer surfaces of the two guide rods 4 are respectively fixedly connected with the two connecting plates 6, and the outer surfaces of the two connecting plates 6 are rotatably connected The support tube 7 is connected, and the inside of the two support tubes 7 is provided with an adjusting rod 8. The outer surfaces of the two adjusting rods 8 away from the support tube 7 are rotatably connected to the first rotating seat 10. The outer surfaces of the two first rotating seats 10 are fixedly connected to the pad 9. The front outer surfaces of the two cross plates 3 are fixedly connected to the scale plate 11. The outer surface of one end of the guide rod 4 away from the connecting plate 6 is fixedly connected to the benchmark rod 12. In this embodiment, the length between the adjusting rod 8 and the support tube 7 is adjusted, and the position of the pad 9 is adjusted so that the pad 9 contacts the slope and is fixed on the first rotating seat. Under the action of 10, the pad 9 can be rotated so that the pad 9 can only fit the slope, and the length between the adjusting rod 8 and the supporting tube 7 is continued to be adjusted. At this time, one end of the pad 9 cannot move, so the spring 5 is stressed and compressed to a certain extent, and the preparation work is completed. At this time, the position of the scale line of the benchmark 12 on the scale plate 11 is observed, and the value corresponding to the benchmark 12 is recorded. When the slope is displaced with a larger inclination angle, the pad 9 moves with the movement of the slope. After the pad 9 is stressed, force is applied to the spring 5, so that the spring 5 is further compressed. The spring 5 shrinks and drives the connecting plate 6 to squeeze the guide rod 4, so that the benchmark 12 moves. The displacement of the slope is determined by comparing the position of the scale line of the benchmark 12 on the scale plate 11 with the initial value. When the slope is displaced with a tilt angle, the spring 5 applies a certain reset force as the slope moves, so that the pad 9 is close to the slope. The spring 5 drives the connecting plate 6 to move, and the connecting plate 6 drives the guide rod 4 to move the benchmark 12. The displacement of the slope is determined by comparing the position of the scale line of the benchmark 12 on the scale plate 11 with the initial value.

[0025] A first fixing nail 13 is fixedly connected at the center of the bottom outer surface of the base 1, and three second rotating seats 14 are arranged in a circular array on the outer surface of the vertical rod 2. The outer surfaces of the three second rotating seats 14 are all rotatably connected with a fixing rod 15, and a movable rod 16 is movably inserted inside the three fixing rods 15. Screw holes 17 are opened on the outer surfaces of the fixing rods 15 and the movable rods 16. The number of screw holes 17 on the surface of the movable rod 16 is several, and the screw holes 17 corresponding to the fixing rods 15 and the movable rods 16 are internally threadedly connected with screws 18. The outer surface of the movable rod 16 away from the fixing rod 15 is rotatably connected with a third rotating seat 19, and the bottom outer surface of the third rotating seat 19 is fixedly connected There is a second fixing nail 20. In this embodiment, the first fixing nail 13 is nailed into the ground to fix the base 1 to the ground, and the fixing rod 15 is rotated so that the fixing rod 15 rotates between the second rotating seat 14, and the screw 18 is unscrewed to adjust the distance between the fixing rod 15 and the movable rod 16, and the third rotating seat 19 rotates on the surface of the movable rod 16, and the second fixing nail 20 is nailed into the ground, and then the screw 18 is screwed into the corresponding screw hole 17 to limit the fixing rod 15 and the movable rod 16. Through the support of the fixing rod 15 and the movable rod 16, the overall stability of the base 1 is increased, so that the device is not easily tipped over by external force during detection.

[0026] Two symmetrically arranged mounting plates are fixedly connected to the outer surface of one side of the scale plate 11 close to the benchmark 12, and pressure sensors 21 are fixedly installed between the outer surfaces of the two mounting plates opposite to the benchmark 12. A controller is fixedly installed on the outer surface of the vertical rod 2 (not shown in the figure). The pressure sensor 21 is electrically connected to the controller. In this embodiment, when the slope has a large displacement, the benchmark 12 is driven to contact the pressure sensor 21. The pressure sensor 21 sends a signal to the controller, the controller receives the signal, and sends the signal to the control terminal, so that the staff can perform corresponding processing on the slope in time to avoid safety hazards. It should be noted here that the control terminal can be a mobile phone or a computer.

[0027] The outer surface of the scale plate 11 is provided with scale lines. In this embodiment, the scale lines are provided to facilitate the staff to observe the position of the benchmark 12 and thus determine the amount of slope displacement.

[0028] The inside of the support tube 7 is provided with internal threads, and the outside of the adjusting rod 8 is provided with external threads that match the internal threads. In this embodiment, the support tube 7 is connected to the internal threads of the adjusting rod 8, so that when the support tube 7 and the adjusting rod 8 are rotated, the length between the support tube 7 and the adjusting rod 8 can be adjusted.

[0029] The outer surface of the base 1 is provided with three through grooves in a circumferential array. In this embodiment, by providing the through grooves, when the fixing rod 15 and the movable rod 16 are accommodated, the through grooves provide space for accommodating the second fixing nail 20 .

[0030] Working principle: When the utility model is in use, the first fixing nail 13 is nailed into the ground, thereby fixing the base 1 to the ground, and the fixing rod 15 is rotated so that the fixing rod 15 rotates between the second rotating seat 14, and the screw 18 is screwed down to adjust the distance between the fixing rod 15 and the movable rod 16, and the third rotating seat 19 rotates on the surface of the movable rod 16, and the second fixing nail 20 is nailed into the ground, and then the screw 18 is screwed into the corresponding screw hole 17, and the fixing rod 15 and the movable rod 16 are limited. Through the support of the fixing rod 15 and the movable rod 16, the overall stability of the base 1 is increased. The device is not easily overturned by external force during detection. After the base 1 is fixed, two staff members adjust the distance between the support tube 7 and the adjusting rod 8 at the same time. At this time, they hold the adjusting rod 8 with one hand and twist the support tube 7 with the other hand to rotate the support tube 7. Under the thread engagement force, the length between the adjusting rod 8 and the support tube 7 is adjusted, and the position of the pad 9 is adjusted so that the pad 9 contacts the slope. Under the action of the first rotating seat 10, the pad 9 can be rotated so that the pad 9 can only fit the slope. The length between the adjusting rod 8 and the support tube 7 is continued to be adjusted. At this time, one end of the pad 9 has no The spring 5 is forced to move, and the spring 5 is compressed to a certain extent, and the preparation work is completed. At this time, the position of the scale line of the benchmark 12 on the scale plate 11 is observed, and the value corresponding to the benchmark 12 is recorded. When the slope is displaced with a larger inclination angle, the pad 9 moves with the movement of the slope. After the pad 9 is forced, force is applied to the spring 5, so that the spring 5 is further compressed, and the connecting plate 6 is driven to squeeze the guide rod 4, so that the benchmark 12 moves. By comparing the position of the scale line of the benchmark 12 on the scale plate 11 with the initial value, the amount of slope displacement can be judged. When the slope is displaced with a lower inclination angle, As the slope moves, the spring 5 applies a certain reset force, so that the pad 9 is close to the slope, the spring 5 drives the connecting plate 6 to move, and the connecting plate 6 drives the guide rod 4 to move the benchmark 12. By observing the position of the scale line of the benchmark 12 on the scale plate 11 and comparing it with the initial value, the amount of slope displacement is judged. When the displacement is large during the detection process, when the benchmark 12 contacts the pressure sensor 21, the pressure sensor 21 sends a signal to the controller, the controller receives the signal, and sends a signal to the control terminal, so that the staff can perform corresponding processing on the slope in time to avoid safety hazards.

[0031] The controller is an existing structure, and the control circuit can be implemented through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
