Description

Technical Field

[0001] The invention relates to the technical field of soil layer monitoring, in particular to a convenient deep displacement monitoring rod for preventing and controlling loess landslides. Background Art

[0002] Loess landslide is a phenomenon in which the soil in thick loess and high slope areas slides down along a weak surface under the action of gravity. It often occurs on both sides of rivers and dams. In slope management, embankment filling, earth excavation, foundation treatment and other projects, deep horizontal displacement monitoring of the soil is required to understand the displacement and deformation of the soil at different depths during the construction process and ensure construction safety. Deep horizontal displacement is usually detected by using displacement monitoring rods to detect the displacement of deep loess. However, during use, the existing detection rods are very long because some loess layers are relatively thick, up to 20 meters deep. Therefore, the required displacement detection rods are difficult to transport with ordinary vehicles and lack portability.

A rocking wheel 209 is fixedly connected to the right end of the outer surface of the winding roller 205, so that the staff can calculate the soil layer displacement according to the number of revolutions of the counting wheel 207.

[0028] In the present invention, in order to further facilitate the insertion of the splicing rod 1 into the soil layer, the driving device 3 includes a base frame 301, and the top of the inner wall of the base frame 301 is rotatably connected to two sets of rotating rods 302. The front side of the outer surface of the rotating rod 302 is fixedly sleeved with an output gear 303, and the output gear 303 is meshed with the rack 6. The rear side of the outer surface of the rotating rod 302 is fixedly sleeved with two sets of arc-shaped meshing transmission gears 304. The rear side of the outer surface of the rotating rod 302 on the right is fixedly sleeved with a driven gear 305. The inserted rotating shaft 306 is horizontally rotatably connected to a driving gear 307 that meshes with the driven gear 305. A driving motor 308 is fixedly installed on the back of the base frame 301. The output end of the driving motor 308 is fixedly connected to the rear end of the rotating shaft 306. Pins 309 are inserted on the left and right sides of the outer surface of the base frame 301. A stabilizing ring 310 for the splicing rod 1 to pass through is fixedly connected to the inner wall of the front side of the base frame 301, so that the output gear 303 drives the splicing rod 1 to move downward, thereby allowing the splicing rod 1 to be inserted into the soil layer.

[0029] In the present invention, in order to further enhance the rotation stability of the rotating rod 302, two sets of ball bearings are provided on the front and back of the base frame 301. The base frame 301 is rotatably connected to the rotating rod 302 through the ball bearings. By providing the ball bearings, the rotation stability of the rotating rod 302 is further enhanced.

[0030] In the present invention, in order to further enhance the rotational stability of the output gear 303, the transmission gear 304 and the driven gear 305, a connecting key is fixedly connected to the outer surface of the rotating rod 302, and the inner walls of the output gear 303, the transmission gear 304 and the driven gear 305 are all provided with key slots adapted to the connecting key. The connecting key cooperates with the key slot, thereby further enhancing the rotational stability of the output gear 303, the transmission gear 304 and the driven gear 305.

[0031] In the present invention, in order to further enhance the stability of the movement of the arc-shaped splint 202, two sets of I-shaped slide bars are fixedly connected to the left inner wall and the right inner wall of the rectangular frame 201, and the outer surface of the arc-shaped splint 202 is provided with an I-shaped slide groove that is compatible with the I-shaped slide bar. The I-shaped slide bar cooperates with the I-shaped slide groove, thereby further enhancing the stability of the movement of the arc-shaped splint 202.

[0032] In the present invention, in order to further enhance the stability of the arc-shaped splint 202 clamping, an anti-slip pad is provided on the inner wall of the arc-shaped splint 202. The material of the anti-slip pad is rubber, and the outer surface of the anti-slip pad is provided with anti-slip textures, thereby enhancing the friction between the arc-shaped splint 202 and the splicing rod 1, and further enhancing the stability of the arc-shaped splint 202 clamping.

[0033] In the present invention, in order to further reduce the possibility of the winding roller 205 rotating on its own, a friction screw 210 is threadedly connected to the top of the right side of the V-shaped plate 204 located on the right side. The left end of the friction screw 210 is in contact with the right side of the winding roller 205, so that there is a certain friction between the friction screw 210 and the winding roller 205, further reducing the possibility of the winding roller 205 rotating on its own.

[0034] In the present invention, in order to prevent the wire rope 13 from escaping from the threading groove 102, the threading groove 102 on the splicing rod 1 at the bottom faces straight ahead, and the threading groove 102 on the splicing rod 1 at the top faces straight behind, so that the threading grooves 102 of adjacent splicing rods 1 face opposite directions, which limits the wire rope 13 and prevents the wire rope 13 from escaping from the threading groove 102.

[0035] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0036] When in use, take a set of splicing rods 1 and insert them into the stabilizing ring 310, so that the rack 6 is engaged with the output gear 303, and the connecting groove 701 on the connecting column 7 is set outside the plug block 4 of this splicing rod 1, and the connecting bolt 8 is installed to fix the connecting column 7 and the splicing rod 1, and the wire rope 13 is placed in the threading groove 102, and the base frame 301 is fixed in the monitoring position by the pin 309, and the driving motor 308 is started. The output end of the driving motor 308 drives the rotating shaft 306 and the driving gear 307 to rotate, and the driving gear 307 drives the rotating rod 3 on the right side through the driven gear 305. 02 rotates, the rotating rod 302 on the right side drives the rotating rod 302 on the left side to rotate in the opposite direction through two sets of transmission gears 304, the rotating rod 302 drives the output gear 303 to rotate, and the output gear 303 drives the splicing rod 1 to move downward, and the drilling cone 11 is inserted into the soft soil layer. When the top of the first splicing rod 1 is about to move to the bottom of the output gear 303, the drive motor 308 is turned off, and the second set of splicing rods is installed on the first splicing rod 1. And so on, until the drilling cone 11 reaches the specified soil layer depth. When the two sets of splicing rods 1 are further spliced, the top splicing rod is moved downward. 1 is inserted into the slot 101, and then the fixing bolt 5 is installed to complete the assembly of the two sets of splicing rods 1. When assembling, it is important to note that the adjacent splicing rods 1 need to be assembled in reverse order, that is, the directions of the threading grooves 102 of the adjacent splicing rods 1 cannot be the same. When the drilling cone 11 reaches the specified soil depth, the arc-shaped clamping plate 202 is inserted into the top of the splicing rod 1 at the top, and the threaded rod 203 is rotated to clamp the arc-shaped clamping plate 202 to fix the splicing rod 1. The friction screw 210 is rotated to create a certain friction between the friction screw 210 and the winding roller 205 to prevent the winding roller 205 from rotating. The driving motor 308 is rotated in the opposite direction to lift the splicing rod 1 upward for a distance. When the splicing rod 1 is lifted, the drilling cone 11 is squeezed and fixed in the soil layer, and the drift ball 12 is released. The drift ball 12 flows with the soil layer, and the drift ball 12 pulls the wire rope 13. The wire rope 13 drives the counting wheel 207 to rotate. The rotary counter 208 counts the number of rotations of the counting wheel 207. The number of rotations is multiplied by the diameter of the counting wheel 207 to obtain the value of the soil layer offset. After the detection is completed, the driving motor 308 is controlled to reverse to remove the splicing rod 1, the drilling cone 11, the drift ball 12 and other devices.
