Description

Technical Field

[0001] The invention belongs to the technical field of geotechnical engineering investigation, and in particular relates to a geotechnical engineering investigation safety monitoring device. Background Art

[0002] In the field of geotechnical engineering, the anchor rods of the vibrating-string displacement monitor are often buried underground at the construction site to monitor the displacement and settlement of the rock and soil. Through data recording and monitoring, the internal changes of the structure can be grasped in real time, which plays a role in safety investigation. During installation, since the anchor rod of the vibrating-string displacement monitor has a threaded groove that can be self-drilled, the vibrating-string displacement monitor can be rotated to allow the anchor rod to drill into the ground. When the monitoring is canceled, the anchor rod can be taken out from the ground. The vibrating-string displacement monitor is usually placed in a matching support box for storage. Generally, when storing the vibrating-string displacement monitor, the staff usually does not clean the soil in the threaded groove of the anchor rod before storing it in the support box. If the soil is not cleaned, the long-term adhesion of the soil may corrode the anchor rod, which will easily affect the monitoring accuracy of the string displacement monitor in the long run. Therefore, in order to solve the above problems, we propose a geotechnical engineering investigation safety monitoring equipment. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-7 As shown, a geotechnical engineering investigation safety monitoring device of the present invention includes a vibrating-wire displacement monitoring meter 1 and a supporting box 11. The lower end of the vibrating-wire displacement monitoring meter 1 is provided with an anchor seat 2, the lower end of the anchor seat 2 is provided with a displacement meter outer sleeve 21, the lower end of the displacement meter outer sleeve 21 is provided with a displacement meter adapter 22, and the lower end of the displacement meter adapter 22 is provided with an anchor rod 23.

[0028] A cylinder 3 is fixedly connected to the top of the inner side of the support box 11, and an upper ring plate 31 and a lower ring plate 311 are respectively provided on the upper and lower sides of the cylinder 3. An inner gear ring 312 is rotatably connected in the lower ring plate 311. A horizontal shaft 313 is rotatably connected to the support box 11, and rollers 314 are provided at both ends of the horizontal shaft 313. A cam 32 is provided in the middle of the horizontal shaft 313. A hollow gear cylinder 34 abutting against the upper end of the cam 32 is sleeved in the inner gear ring 312, and the outer side of the hollow gear cylinder 34 is meshed with the inner side of the inner gear ring 312. A number of brushes 35 are evenly provided on the inner wall of the hollow gear cylinder 34, and the width of the cam 32 is smaller than the inner diameter of the hollow gear cylinder 34.

[0029] The lower end of the lower ring plate 311 is rotatably connected to the vertical shaft 4, the middle part of the vertical shaft 4 is fixedly connected to an intermediate gear 41 meshing with the hollow gear cylinder 34, the lower end of the vertical shaft 4 is fixedly connected to a first bevel gear 42, the horizontal shaft 313 is fixedly connected to a second bevel gear 43 meshing with the first bevel gear 42, and the lower end of the support box 11 is provided with a through groove 6 corresponding to the hollow gear cylinder 34.

[0030] A vibrating-string reading instrument 5 is provided on the outside of the supporting box 11, a battery 51 electrically connected to the vibrating-string reading instrument 5 is fixedly connected to the inside of the supporting box 11, the vibrating-string reading instrument 5 is provided with a first data socket, the vibrating-string displacement monitor 1 is provided with a second data interface 53, a data transmission line 54 is connected between the first data socket and the second data interface 53, and a storage groove 62 is provided on the upper end of the supporting box 11, and the storage groove 62 can be used to store the data transmission line 54 that is not in use.

[0031] Under the action of gravity, the hollow gear cylinder 34 will maintain contact with the upper end of the cam 32, and the gear ring 312 can horizontally limit the hollow gear cylinder 34. In the initial state, the vibrating wire displacement monitor 1 and its connection structure are stored in the cylinder 3 on the support box 11, and the upper ring plate 31 cooperates with the anchor seat 2 to support and limit the vibrating wire displacement monitor 1 and its connection structure. When in the storage state, the part of the anchor rod 23 with the thread groove will be located in the hollow gear cylinder 34, and the plurality of brushes 35 in the hollow gear cylinder 34 will elastically contact the side of the anchor rod 23 and the inner wall of the thread groove.

[0032] The lower part of the support box 11 is V-shaped when viewed from the plane perpendicular to the horizontal axis 313. The lower part of the support box 11 is V-shaped so that when the support box 11 falls on the ground, the opening of the cylinder 3 faces obliquely upward, which makes it convenient to take the vibrating-wire displacement monitor 1 and its connection structure. The vibrating-wire reading instrument 5 is arranged on the side plate of the support box 11 perpendicular to the horizontal axis 313. The connection between the vibrating-wire reading instrument 5 and the side plate of the support box 11 is a rotation connection. The center of gravity of the vibrating-wire reading instrument 5 is located below the center of rotation. In this way, when the support box 11 is in a tilted state, the vibrating-wire reading instrument 5 can remain in a vertical state under the action of gravity, which makes it convenient for the staff to read and operate.

[0033] A handle 61 is provided on both the front and rear sides of the upper end of the support box 11. The handle 61 is in an inverted U shape. Two rollers 314 are used to support the support box 11 in a rolling manner. The user can pull the handle 61 to roll the support box 11 on the ground, which is convenient for moving the entire device and improves the portability of the entire device. The battery 51 is used to power the vibrating-wire displacement monitor 1 and the vibrating-wire reading instrument 5. When in use, the vibrating-wire displacement monitor 1 and its connecting structure are pulled out of the cylinder 3, and then the anchor rod 23 on the vibrating-wire displacement monitor 1 is drilled into the rock and soil that needs to be safely monitored, and then one end of the data transmission line 54 is plugged into the first data socket and the other end is plugged into the second data interface 53. The vibrating-wire displacement monitor 1 can be powered on and operated by the vibrating-wire reading instrument 5, and the staff can read the corresponding monitoring data through the display screen of the vibrating-wire displacement monitor 1.

[0034] When storing the vibrating wire displacement monitor 1, the anchor rod 23 of the vibrating wire displacement monitor 1 is pulled out from the rock and soil, and then the vibrating wire displacement monitor 1 and its connecting structure are stored in the cylinder 3 on the support box 11. When the staff pulls the support box 11 to move, the roller 314 can drive the horizontal shaft 313 to rotate, and when the horizontal shaft 313 rotates, it can drive the cam 32 and the second bevel gear 43 to rotate. When the second bevel gear 43 rotates, it can cooperate with the first bevel gear 42 and the intermediate gear 41 to drive the hollow The gear cylinder 34 rotates, and the hollow gear cylinder 34 can drive the brush 35 inside it to brush the side of the anchor rod 23 and the inner wall of the threaded groove laterally when rotating, thereby cleaning the attached soil. The cam 32 will drive the hollow gear cylinder 34 to cyclically move up and down during the rotation process. When the hollow gear cylinder 34 moves up and down, the brush inside it will brush the side of the anchor rod 23 and the inner wall of the threaded groove longitudinally, further improving the cleaning effect. The cleaned soil will be discharged through the through groove 6 under the action of gravity.

[0035] It can be seen from this that even if the staff does not clean the soil in the thread groove of the anchor rod 23, the internal structure of the support box 11 can automatically clean it during the subsequent movement of the support box 11, thereby preventing the soil from adhering to the thread groove of the anchor rod 23 for a long time and causing corrosion to the anchor rod 23.

[0036] The first bevel gear 42 and the second bevel gear 43 have the same number of teeth, and the middle gear 41 has a greater number of teeth than the hollow gear cylinder 34 , which can reduce speed and increase torque, so that the hollow gear cylinder 34 can obtain a larger torque force to improve the cleaning ability.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
