Description

Technical Field

[0001] This invention relates to the field of deformation monitoring device technology, and in particular to a foundation pit slope deformation monitoring device. Background Technology

[0002] During the construction of highways, railways, mines, dams, and other engineering projects, slopes composed of earth, sand, gravel, and rock masses, either artificially or naturally formed, are inevitably created. Slopes are complex, deformable structures that are susceptible to deformation due to various internal and external factors, leading to landslides, economic losses, and even casualties. Therefore, monitoring slope deformation in highway, railway, mine, and dam projects, analyzing their stability, assessing the risks posed by slope deformation, and providing early warnings of potential landslides are extremely important tasks.

[0003] Slope deformation monitoring typically uses guide wheel type fixed inclinometers. Before use, multiple guide wheel type fixed inclinometers need to be fixed at different positions on the wire rope to achieve slope deformation monitoring at different depths. Guide wheel type fixed inclinometers are generally fixed to the wire rope with U-shaped wire rope clips. This method requires the U-shaped wire rope clips to be carried separately, and the accessories are easily lost during transportation. In addition, two nuts need to be tightened during installation, making operation inconvenient. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for monitoring the deformation of foundation pit slopes.

[0005] The objective of this invention is achieved through the following technical solution: A device for monitoring the deformation of a foundation pit slope includes an inclinometer body, wherein the inclinometer body is a guide wheel type fixed inclinometer, and the inclinometer is fixed to a steel wire rope by a quick-fixing component; The quick-fixing assembly includes a base fixed to the inclinometer body. The base has an arc-shaped open slot and a connecting part. The base is connected to a clamping part through the connecting part.

[0007] Furthermore, the clamping part includes a clamping sleeve, the inner wall of which is provided with an internal thread adapted to the external thread, and the clamping sleeve is connected to the connecting cylinder through the internal thread and the external thread.

[0008] Furthermore, the end of the clamping sleeve away from the connecting cylinder is provided with a cap, and the cap is provided with rotating ribs.

[0009] Furthermore, the inner side of the cover is provided with a pressure rod coaxial with the clamping sleeve.

[0010] Furthermore, the clamping sleeve is rotatably connected to the base via a connecting assembly.

[0011] Furthermore, the outer wall of the pressing sleeve is provided with a relief groove along the axial direction, and the connecting assembly includes a snap-fit ​​ring and a rotating column. The snap-fit ​​ring is rotatably sleeved in the relief groove, and the snap-fit ​​ring can move along the axial direction of the pressing sleeve in the relief groove. The snap-fit ​​ring is integrally connected to the rotating column, and the snap-fit ​​ring is rotatably connected to the base through the rotating column.

[0012] Furthermore, the base has two ear plates fixedly mounted on its side wall, each ear plate having a rotating hole, and the rotating column is rotatably connected to the ear plate through the rotating hole.

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] See Figures 1-6 The present invention provides a technical solution: Example

[0018] like Figures 1-6 As shown, a foundation pit slope deformation monitoring device includes an inclinometer body 1, which is a guide wheel type fixed inclinometer, and the inclinometer is fixed to a steel wire rope 2 by a quick-fixing component; The quick-fixing assembly includes a base 3 fixed to the inclinometer body 1. The base 3 is provided with an arc-shaped open slot 4 and a connecting part 5. The base 3 is connected to a pressing part through the connecting part 5. The pressing part cooperates with the open slot 4 to press and fix the wire rope 2 between the base 3 and the pressing part.

[0019] The connecting part 5 includes a connecting cylinder 6 provided at the open end of the opening slot 4. The outer wall of the connecting cylinder 6 is provided with external threads, and the connecting cylinder 6 is provided with a notch along the axial direction. The notch communicates with the opening slot 4. The clamping part is threadedly connected to the connecting cylinder 6.

[0020] The clamping part includes a clamping sleeve 7, the inner wall of which is provided with an internal thread that is adapted to the external thread, and the clamping sleeve 7 is connected to the connecting cylinder 6 through the internal thread and the external thread.

[0021] The end of the clamping sleeve 7 away from the connecting cylinder 6 is provided with a cover 8, and the cover 8 is provided with a rotating rib 9.

[0022] The inner side of the cover 8 is provided with a pressure rod 10 coaxial with the clamping sleeve 7. The end of the pressure rod 10 does not extend beyond the cover 8.

[0023] The clamping sleeve 7 is rotatably connected to the base 3 via a connecting assembly.

[0024] like Figure 5As shown, the outer wall of the pressing sleeve 7 is provided with a relief groove 11 along the axial direction (wherein, the inner diameter of the relief groove 11 is smaller than the outer diameter of the pressing sleeve 7 and is adapted to the inner diameter of the snap ring 12). The connecting assembly includes a snap ring 12 and a rotating column 13. The snap ring 12 is rotatably sleeved in the relief groove 11, and the snap ring 12 can move along the axial direction of the pressing sleeve 7 in the relief groove 11. The snap-fit ​​ring 12 is integrated with the rotating column 13, and the snap-fit ​​ring 12 is rotatably connected to the base 3 through the rotating column 13.

[0025] like Figure 3 As shown, the base has two ear plates 14 fixedly mounted on its side wall, with corresponding upper and lower ear plates 14. The ear plates 14 have rotating holes, and the rotating column 13 is rotatably connected to the ear plates 14 through the rotating holes.

[0026] The snap ring 12 is fixedly connected to the upper and lower ends of the rotating column 13 via the connecting rod 15.

[0027] Specifically, 1. A fixing plate is welded to the end of the inclinometer body 1, and then the base 3 is welded and fixed to the fixing plate. Alternatively, the base 3 can be directly welded to the inclinometer body 1. In addition, for easy disassembly, a connecting groove can be set on the side of the base 3 away from the wire rope 2. After the fixing plate is inserted into the connecting groove, the two are fixed with bolts (threaded holes are prepared in advance).

[0028] Working principle: When in use, the first and last ends of multiple inclinometer bodies 1 are quickly fixed to the steel wire rope 2 using quick-fixing components. After installation, the cables of each inclinometer body 1 are bundled together and aligned with the steel wire rope 2 to the lifting ring at the orifice.

[0029] After binding, fold the steel wire rope 2 in half about 30cm from the beginning of the rope and secure it with a steel rod, then tighten it. Number and record the inclinometer body 1 in sequence, and ensure that all cables are slack. Then, align the positive direction (high wheel direction) of the guide wheel on the inclinometer body 1 with the main direction of the measuring plane of the quasi-inclinometer tube inserted into the slope, and then you can start measuring.

[0030] The process of fixing the inclinometer body 1 and the wire rope 2 is as follows: Tighten the clamping part to disengage the clamping part from the connecting part 5, and rotate the clamping part 90 degrees around the rotating column 13 to open the opening slot 4. At this time, the wire rope 2 is inserted through the opening. Then rotate the clamping part to reset it (that is, the internal thread of the clamping part is aligned with the external thread of the connecting column 6).

[0031] After the clamping part is reset, tighten the clamping part to engage with the external thread until the clamping column inside the clamping part presses against the wire rope 2 (in addition to being pressed by the clamping column, the wire rope 2 is also pressed by the clamping teeth provided on the end face of the clamping sleeve 7), so that the wire rope 2 is firmly clamped between the clamping part and the base 3.

[0032] The clearance groove 11 provided on the clamping sleeve 7 provides clearance for the locking ring 12 when the clamping sleeve 7 is screwed into the external thread, so as to prevent the locking ring 12 from limiting the clamping sleeve 7.

[0033] This invention enables the rapid fixing of the inclinometer body to the wire rope by setting up a quick-fixing component. The quick-fixing component is connected to the inclinometer body as one unit, eliminating the possibility of omissions or missing parts during transportation and greatly facilitating the use of the inclinometer.
