Description

Technical Field

[0001] The utility model relates to the technical field of inclinometer tubes, and more specifically, to an inclinometer tube structure used for geotechnical engineering detection. Background Art

[0002] Inclinometer tube is a device used to monitor the horizontal displacement of piles or soil in geotechnical engineering inspection. Inclinometer tube is usually made of plastic or metal materials, and its structure is designed to be installed on the ground or in a borehole to monitor the inclination change of soil or structure. During the use of existing inclinometer tube, the unstable fixation of the bottom of the borehole will cause soil disturbance and instability of the inclinometer tube, which will cause errors in the measurement results.

[0003] After searching, a Chinese patent with announcement number CN212903115U discloses a geotechnical engineering inclinometer tube. The guide slider will push the push plate downward to push the fixed spear out of the first tube body, and the pointed head will penetrate into the bottom of the hole. Under the action of the spring force, the fixed blade will cut into and penetrate into the rock and soil on both sides of the borehole. At this time, the guide slider has slid to the lower end of the first guide groove and the buckle locks the position of the guide slider, completing the fixation of the bottom inclinometer tube body in the borehole. The fixing effect is good and it is not easy to affect the measurement structure.

[0004] When the above-mentioned inclinometer tube is in use, the guide slider is pressed along the radial direction of the extension tube through the first through hole or the second through hole to make it disengage from each guide groove, so that the extension tube can be disassembled. However, it is inconvenient to detect whether the extension tube is tilted. An inclinometer is needed to measure whether the tube body is tilted, and the use effect is poor. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an inclinometer tube structure for geotechnical engineering detection, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inclinometer tube structure for geotechnical engineering detection, comprising an inclinometer tube main body, an extension tube movably arranged on the top of the inclinometer tube main body, an L-shaped plate movably arranged on the top of the extension tube, an inner side of the L-shaped plate movably connected with a rotating shaft through a bearing, and one end of the rotating shaft is fixedly connected to the extension tube, an inner side of the L-shaped plate and fixedly connected with a scale plate at an outer position of the rotating shaft, a fixing ring is provided on the outer side of the extension tube and at a position at the bottom of the rotating shaft, and an edge ring is provided on the fixing sleeve at the outer top edge position of the inclinometer tube main body.

[0007] Furthermore, a connecting assembly is provided between the side ring and the fixed ring, and the connecting assembly includes positive and negative screw rods, two sliding blocks, two limit blocks and two plug blocks.

[0008] Furthermore, the forward and reverse screw rods are movably connected to the extension tube via bearings, the two sliders are threadedly connected to the forward and reverse screw rods, and the top ends of the two sliders are respectively fixedly connected to the two limit blocks, the top ends of the two limit blocks extend into the fixing ring, the opposite sides of the two plug blocks are respectively fixedly connected to the two sliders, and the facing sides of the two plug blocks extend into the side ring.

[0009] Furthermore, side plates are movably provided on opposite sides of the two sliding blocks, and the opposite sides of the two side plates are fixedly connected to the forward and reverse screw rods.

[0010] It can be seen that in the above technical solution, the forward and reverse screws are driven to rotate conveniently while limiting the moving distance of the slider.

[0011] Furthermore, a transverse plate is fixedly connected to one side of the L-shaped plate, and a fixing assembly is provided on the transverse plate. The fixing assembly includes a vertical pole, a mounting plate, a screw rod and a threaded sleeve.

[0012] Furthermore, the top end of the vertical rod is in contact with the horizontal plate, the top end of the mounting plate is fixedly connected to the vertical rod, the bottom end of the screw rod passes through the horizontal plate and is fixedly connected to the vertical rod, and the threaded sleeve is movably mounted on the screw rod.

[0013] Furthermore, a clamping block is fixedly connected to the top of the vertical rod and located inside the horizontal plate, and the clamping block is fixedly sleeved on the screw rod.

[0014] It can be seen that in the above technical solution, the threaded sleeve is rotated and moved away from the cross plate, and then the vertical pole is moved horizontally and the block is made to slide in the cross plate, which can prevent the vertical pole from deflecting, and finally the distance between the vertical pole and the inclinometer tube body is adjusted according to needs.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model places the extension tube on the top of the inclinometer tube body and rotates the side plate, thereby driving the forward and reverse screws to rotate. The forward and reverse screws can drive the two sliders to move toward each other, thereby driving the two plugs to move toward each other into the edge ring, thereby fixing the inclinometer tube body and the extension tube. Similarly, the extension tube is disassembled. When the inclinometer tube body is tilted, the extension tube tilts along with the inclinometer tube body. The inclination angle of the extension tube is observed through the scale plate, and there is no need to use an inclinometer to measure whether the tube body is tilted, and the use effect is good;

[0017] 2. The utility model places the mounting plate on the base, fixes the mounting plate to the soil through four bolts, rotates the threaded sleeve and makes it contact with the cross plate, thereby limiting and fixing the vertical rod, and then limiting and fixing the L-shaped plate. The utility model has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Furthermore, a connecting assembly 5 is provided between the side ring 2 and the fixed ring 4, and the connecting assembly 5 includes a forward and reverse screw rod 501, two sliders 502, two limit blocks 503 and two plug blocks 504. The forward and reverse screw rod 501 is movably connected to the extension tube 3 through a bearing, the two sliders 502 are both threadedly connected to the forward and reverse screw rod 501, and the top ends of the two sliders 502 are respectively fixedly connected to the two limit blocks 503, the top ends of the two limit blocks 503 extend into the fixed ring 4, the opposite sides of the two plug blocks 504 are respectively fixedly connected to the two sliders 502, and the opposite sides of the two plug blocks 504 extend into the side ring 2, the opposite sides of the two sliders 502 are movably provided with side plates 505, and the opposite sides of the two side plates 505 are fixedly connected to the forward and reverse screw rod 501.

[0029] Furthermore, one side of the L-shaped plate 6 is fixedly connected to a horizontal plate 10, and a fixing component 9 is provided on the horizontal plate 10. The fixing component 9 includes a vertical rod 901, a mounting plate 902, a screw rod 904 and a threaded sleeve 905. The top end of the vertical rod 901 contacts the horizontal plate 10, the top end of the mounting plate 902 is fixedly connected to the vertical rod 901, the bottom end of the screw rod 904 passes through the horizontal plate 10 and is fixedly connected to the vertical rod 901, the threaded sleeve 905 is movably sleeved on the screw rod 904, and a clamping block 903 is fixedly connected to the top end of the vertical rod 901 and located inside the horizontal plate 10, and the clamping block 903 is fixedly sleeved on the screw rod 904.

[0030] Among them, the mounting plate 902 is placed on the base, and the mounting plate 902 is fixed to the soil by four bolts, and the threaded sleeve 905 is rotated to make it contact with the cross plate 10, so as to limit and fix the vertical rod 901, and then limit and fix the L-shaped plate 6.
