Description

Technical Field

[0001] The present application relates to the field of monitoring technology, and in particular to a device for repairing stuck pipes of a monitoring inclinometer. Background Art

[0002] Inclinometers are currently used to measure the top and azimuth angles of engineering structures such as boreholes, foundation pits, foundations, walls, and dam slopes. The basic configuration of an inclinometer includes a measuring guide tube, an inclinometer probe, a control cable, and a main unit.

[0003] The measuring tube is embedded in the soil, with two grooves cut into its inner wall for the inclinometer to travel along the tube and collect data. The inclinometer probe is hinged to two guide wheel assemblies at its upper and lower ends. These assemblies consist of a lower guide wheel, a higher guide wheel, and a connecting rod that pivots to the inclinometer probe. The lower and higher guide wheels are fixed to either end of the connecting rod, with an elastic element, such as a torsion spring, positioned between the connecting rod and the inclinometer probe. When the inclinometer probe is lowered, the elastic element in the connecting rod causes the upper and lower guide wheels of the guide wheel assembly to slide against the two grooves in the measuring tube.

[0004] The inclinometer probe also has a built-in tilt sensor for measuring angle changes. Typically, the distance between the upper and lower guide rollers is 0.5 meters. A control cable connects the inclinometer probe to the host computer, providing power and data transmission. The host computer reads the angle data measured by the inclinometer probe and calculates horizontal displacement.

[0005] During actual application, the middle part of the measuring tube may be broken due to construction or misoperation. During the observation and lowering process of the inclinometer, a guide wheel at the lower end of the inclinometer probe passes through the broken part of the measuring tube, causing the inclinometer to tilt. Since the rotational connection between the connecting rod and the inclinometer probe has a negative limit, the guide wheel can only rotate in one direction. That is, the guide wheel pops out into the broken part as the connecting rod opens, and the negative limit causes it to form a hook and get stuck, causing the inclinometer probe to be stuck at the broken part and unable to be retracted.

[0006] In response to the above situation, the common methods currently used are excavation to pull out the inclinometer casing or violent pulling: Excavation and pipe removal treatment method: 1. It is only applicable to inclinometer holes with shallow burial depths, which will damage the inclinometer holes and make them unusable in the future, with great limitations; 2. Excavation will have an adverse effect on the stability of the rock and soil to be monitored.

[0007] Violent pulling treatment method: 1. The vibration and collision caused by violent pulling can easily affect the accuracy of subsequent instruments; 2. Violent pulling can easily cause cable breakage and a low success rate of retrieval. Summary of the Invention

[0008] In order to improve the problem that the inclinometer probe is stuck at a fracture and difficult to retract, the present application provides a monitoring inclinometer stuck pipe repair device.

[0009] This application provides a monitoring inclinometer stuck pipe repair device, which adopts the following technical solutions: A monitoring inclinometer stuck pipe repair device includes a straightening block and a lifting assembly. A guide block for extending into a pipe groove of a measuring conduit is fixed to one side of the straightening block. The side of the straightening block away from the guide block has a guide arc surface that gradually decreases from top to bottom. The lifting assembly is used to control the lifting and lowering of the straightening block so that the guide arc surface of the straightening block squeezes and straightens the measuring probe, allowing the guide wheel to return to the measuring conduit.

[0010] By adopting the above technical solution, the lifting assembly lowers the straightening block. When the straightening block contacts the first high guide wheel, it can squeeze the high guide wheel through the guide arc surface, allowing the high guide wheel to be retracted. After the straightening block successfully passes through the high guide wheel, it continues to move downward. At this time, the straightening block pushes the rod of the measuring probe back to the center. During this process, the lower high guide wheel will follow the straightening rod back to the pipe groove. At this time, the measuring probe can be pulled up and recovered. This solution can effectively solve the problem of the inclinometer probe getting stuck due to the broken measuring pipe during the lowering process, improving the efficiency and safety of emergency repairs.

[0011] Optionally, a connecting rod extending away from the guide block is fixed on the straightening block; the end of the connecting rod away from the straightening block is rotatably connected to a directional wheel, the directional wheel is abutted against the wall of the measuring catheter, and the movable lifting path of the connecting rod and the measuring probe is staggered.

[0012] By adopting the above technical solution, the guiding stability of the device is enhanced, and the correct position of the straightening block during the lifting process is ensured.

[0013] Optionally, the lifting assembly includes a splicing tube, one end of which is fixedly connected to the straightening block; the splicing tube includes a plurality of splicing segments and a splicing piece fixedly connecting adjacent splicing segments.

[0014] By adopting the above technical solution, the length of the emergency repair device can be adjusted according to actual needs to adapt to measuring catheters of different depths.

[0015] Optionally, the splicing piece includes a threaded column coaxially fixed to one end of the splicing section, and a threaded hole for threaded connection of the threaded column is formed at one end of the splicing section away from the threaded column.

[0016] By adopting the above technical solution, the rapid connection and disassembly of the splicing sections is achieved, and the convenience of on-site operation is improved.

[0017] Optionally, a wheel groove for the high guide wheel to pass through is provided on a side of the straightening block away from the guide block, and the width of the wheel groove is smaller than the diameter of the measuring probe rod body.

[0018] By adopting the above technical solution, a wheel groove is opened on the straightening block to allow the high guide wheel to pass through, but restrict the passage of the measuring probe rod. This can reduce the resistance of the high guide wheel passing through the straightening block and facilitate the downward movement of the straightening block.

[0019] Optionally, the lifting assembly includes a pulling rope and several counterweight balls, the counterweight balls are slidably connected to the pulling rope, a vertically extending sleeve is fixed to the upper end of the straightening block, a guide rod extending out of the sleeve is coaxially fixed inside the sleeve, one end of the pulling rope is fixedly connected to one end of the guide rod extending out of the sleeve, and the guide rod is used to guide the counterweight balls on the pulling rope into the sleeve; the length of the sleeve is longer than the length of the measuring probe rod body.

[0020] By adopting the above technical solution, the straightening block can be moved to the position of the measuring probe under the action of its own weight. When the straightening block encounters great resistance and cannot move downward, the counterweight ball on the pulling rope can be slid into the sleeve, and with the help of the gravity acceleration of the counterweight ball from top to bottom, the straightening block is pushed to continue to move downward and the measuring probe is straightened, which facilitates the downward movement of the straightening block.

[0021] Optionally, a plurality of drag-reducing balls are embedded in a side of the guide block away from the straightening block, and the plurality of drag-reducing balls are arranged at equal intervals along the sliding direction of the guide block.

[0022] By adopting the above technical solution, the friction resistance of the straightening block when moving in the measuring tube is reduced, and the smoothness of the operation is improved.

[0023] Optionally, two connecting rods are symmetrically provided on the straightening block, and both of the connecting rods are in an arc-shaped structure extending in an arc toward the wall of the measuring catheter.

[0024] By adopting the above technical solution, the connecting rod is designed to be an arc-shaped structure, and two are symmetrically arranged, thereby enhancing the stability and guidance of the emergency repair device during the descent process.

[0025] Optionally, the outer wall of the sleeve is provided with a guide groove for the high guide wheel to slide.

[0026] By adopting the above technical solution, the guide groove can limit the high guide wheel, so that the high guide wheel moves along the track of the guide groove and is not easily offset.

[0027] In summary, this application has at least one of the following beneficial effects: 1. Effectively solve the problem of the inclinometer probe getting stuck due to the breakage of the measuring tube during the lowering process, improving the efficiency and safety of emergency repairs; 2. The lifting assembly, consisting of a pull rope and a weighted ball, automatically lowers the straightening block through gravity, eliminating the need for an external power source and simplifying operation. The sleeve and guide rod design ensures smooth introduction and guidance of the pull rope, improving repair efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] Example 1 Reference Figure 1 、 2 The embodiment of the present application discloses a device for repairing a stuck pipe of a monitoring inclinometer, comprising a straightening block 1 and a lifting assembly. A guide block 2 is fixed to one side of the straightening block 1. The guide block 2 is used to extend into the pipe groove of the measuring tube 4, so that the straightening block 1 can move along the measuring tube 4 and is not easily offset. The side of the straightening block 1 away from the guide block 2 has a guide arc surface 3 that gradually decreases from top to bottom. The lifting assembly is used to control the lifting and lowering of the straightening block 1, allowing the guide arc surface 3 of the straightening block 1 to squeeze and straighten the position of the measuring probe, so that the guide wheel group 5 returns to the measuring tube 4. The lower end of the guide block 2 is provided with a chamfer 19 to facilitate guiding the high guide wheel onto the guide arc surface 3.

[0032] The design of the straightening block 1 and lifting assembly enables non-destructive repair of a stuck inclinometer probe. The curved guide surface 3 of the straightening block 1 precisely squeezes and straightens the probe, allowing its guide wheel to smoothly return to the pipe trench, avoiding the damage and inconvenience caused by traditional excavation or violent pulling methods.

[0033] Reference Figure 2 、 3 The lifting assembly includes a splicing tube 6, one end of which is welded and fixed to the straightening block 1. Specifically, the splicing tube 6 includes a plurality of splicing sections 7 and a splicing piece that fixedly connects adjacent splicing sections 7. The splicing piece includes a threaded column 8 coaxially fixed to one end of the splicing section 7, and a threaded hole 9 for threaded connection of the threaded column 8 is provided at one end of the splicing section 7 away from the threaded column 8. Through the cooperation of the threaded column 8 and the threaded hole 9, a stable connection of the splicing section 7 is achieved, and disassembly and reassembly are facilitated. In addition, the use of the splicing section 7 as part of the lifting assembly facilitates the operator to flexibly adjust the length of the repair device according to the depth of the measuring tube 4, thereby improving the overall adaptability and flexibility of the device.

[0034] The implementation principle of Example 1: With the help of splicing multiple splicing sections 7 in the splicing tube 6, the straightening block 1 is lowered toward one side of the high guide wheel. When the straightening block 1 contacts the first high guide wheel, it can squeeze the high guide wheel through the guide arc surface 3 to retract the high guide wheel at the upper end. After the straightening block 1 successfully passes through the high guide wheel at the upper end, it continues to move downward. At this time, the straightening block 1 will push the rod body of the measuring probe to return to the center. During the process of the rod body returning to the center, the high guide wheel below will follow the straightening rod body back to the pipe groove. At this time, the measuring probe can be pulled upward to retract the measuring probe.

[0035] Example 2 On the basis of Example 1, Example 2 further improves the design of the straightening block 1. Figure 4 On the side of the straightening block 1, away from the guide block 2, a wheel groove 10 is provided for the high guide wheel to pass through. The width of the wheel groove 10 is smaller than the diameter of the measuring probe rod. This allows the high guide wheel to pass through, but restricts the passage of the measuring probe rod. This reduces the difficulty of the high guide wheel passing through the straightening block 1 while retaining the straightening block 1's ability to continue straightening the probe rod.

[0036] Reference Figure 4 A connecting rod 11 is welded to the straightening block 1, extending away from the guide block 2. The end of the connecting rod 11, away from the straightening block 1, is pivotally connected to a directional wheel 12, which abuts against the wall of the measuring tube 4. Two connecting rods 11 are symmetrically arranged, each forming an arc-shaped structure that extends toward the wall of the measuring tube 4. In other words, the arcs of the two connecting rods 11 are positioned opposite each other. A notch is left at the end of each connecting rod 11 away from the straightening block 1 for the guide wheel to pass through. Furthermore, the curved guide rod 17 does not obstruct the upward movement of the measuring probe.

[0037] In addition, the number of connecting rods 11 can also be one, and this embodiment does not limit the number of connecting rods 11. The connecting rod 11 can be made of plastic or metal with elastic deformation ability, so that the connecting rod 11 has a certain deformation ability, making the downward movement of the straightening block 1 smoother.

[0038] Reference Figure 4 A plurality of drag-reducing balls 13 are embedded on the side of the guide block 2 away from the straightening block 1. The balls 13 are evenly spaced along the sliding direction of the guide block 2. Embedding the drag-reducing balls 13 on the guide block 2 reduces frictional resistance when the repair device slides within the measuring conduit 4, making the descent process smoother.

[0039] Example 3 The difference between this embodiment 3 and embodiment 2 is the lifting assembly. Figure 5 、 6 The lifting assembly includes a pulling rope 14 and a plurality of counterweight balls 15, and the plurality of counterweight balls 15 are slidably connected to the pulling rope 14. A vertically extending sleeve 16 is fixed to the upper end of the straightening block 1, and the length of the sleeve 16 is longer than the length of the measuring probe rod body. A guide rod 17 extending out of the sleeve 16 is coaxially fixed in the sleeve 16, and one end of the pulling rope 14 is fixedly connected to the end of the guide rod 17 extending out of the sleeve 16. The guide rod 17 can be used to guide the counterweight balls 15 on the pulling rope 14 into the sleeve 16. The connection between the pulling rope 14 and the guide rod 17 can be a threaded connection, that is, a sleeve shell is fixed at the end of the pulling rope 14, a screw column is provided at the end of the sleeve shell, and a screw hole is provided at the end of the guide rod 17, and the two are connected by a threaded connection. Of course, the sleeve 16 shell and the guide rod 17 can also be welded. The through hole of the weighted ball 15 passing through the pulling rope 14 is larger than the connection diameter between the pulling rope 14 and the guide rod 17 , and can smoothly pass through the connection between the pulling rope 14 and the guide rod 17 .

[0040] The righting block 1 itself can be constructed of a high-density weight, while the pull rope 14 is constructed of a strong, non-deformable material, such as steel. The righting block 1 automatically descends to the measuring probe's location via gravity. If the righting block 1 is blocked by the probe, several counterweight balls 15 are lowered from the mouth of the measuring conduit 4. Accelerated by gravity, these balls 15 accelerate into the sleeve 16, increasing the weight of the righting block 1 while also leveraging the impact of the drop to propel it further. Single or multiple counterweight balls 15 can be lowered at once, with the number of balls 15 controlled by the desired impact force.

[0041] In this way, with the help of the weight ball 15 and the weight of the straightening block 1 itself, the straightening block 1 can be moved downward and the measuring probe can be straightened. At the same time, the integrated pulling rope 14 is used, and there is no need for splicing operations, which is more convenient.

[0042] Furthermore, the side wall of the sleeve 16 is provided with a guide groove 18 extending along the length direction of the sleeve 16, which is used to provide a guide path for the high guide wheel so that the high guide wheel is not easily offset when moving.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
