A method for solving the problem of probe tube jamming in inclinometers

Abstract

This invention provides a method for solving the problem of inclinometer probe getting stuck in the inclinometer tube. The method involves installing a traction and actuation mechanism on the inclinometer probe to actuate its sliding wheel. The traction and actuation mechanism includes a traction component, a sliding component, a curved shovel, a spring, a movable ring, and a fixed ring. When the inclinometer gets stuck in the gap in the inclinometer tube, the operator pulls the traction rope. The traction rope passes around the pulley and connects to the movable ring. The movable ring drives the curved shovel downwards, pressing against the sliding wheel of the inclinometer, causing the sliding wheel to disengage from the gap. This action on the side surface of the curved shovel effectively solves the problem of the inclinometer probe getting stuck in the inclinometer tube. When the inclinometer is measuring normally, the traction rope is released. Due to the spring action, the curved shovel is positioned above the sliding wheel of the inclinometer, without affecting the measurement results.

Description

Technical Field

[0001] This invention belongs to the field of engineering monitoring technology, specifically relating to a method for solving the problem of probe tube jamming in inclinometers. Background Technology

[0002] Inclinometers are used to monitor the horizontal displacement of retaining piles (walls) and are essential monitoring equipment in engineering monitoring. Currently, inclinometers are divided into sliding and fixed types. Sliding inclinometers are convenient, fast, and widely used. A sliding inclinometer consists of a rod, a sensor (servo accelerometer), positioning wheels, and a data cable. Its principle is to measure the horizontal displacement at each point and calculate the displacement change curve along the depth. Although this device is simple in principle and easy to use, it is prone to getting stuck in the inclinometer tube during engineering use, causing significant economic losses.

[0003] Currently, the depth of foundation pit support piles (walls) is generally 20 to 30 meters, and each inclinometer tube is 2 meters long. Therefore, the inclinometer tubes need to be connected by pipe clamps, and gaps are prone to appear at the joints. When constructing capping beams and retaining walls on the support piles (walls), the inclinometer tubes need to be extended, and gaps are also likely to appear at the joints. Furthermore, the tying of reinforcing bars and pouring of concrete for the capping beams and diaphragm walls can also cause the connected inclinometer tubes to tilt, resulting in gaps at the joints or widening of existing gaps.

[0004] The patent document with patent number CN202121097868.X discloses that in order to clear the blockage in the inclinometer tube, a hole clearer with a Luoyang shovel end was made to prevent the inclinometer probe from getting stuck due to blockage. However, it did not solve the problem of the inclinometer getting stuck in the gap of the inclinometer tube. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of inclinometers getting stuck in the gaps of inclinometer tubes and provides a method to solve the problem of inclinometer probes getting stuck in the tubes.

[0006] This invention is achieved through the following technical solution:

[0007] A method for solving the problem of tube jamming of inclinometer probes is provided by setting a traction and actuation mechanism on the inclinometer probe to actuate the sliding wheel of the inclinometer probe. The traction and actuation mechanism includes: a traction component, a sliding component, a curved shovel, a spring, a movable ring, and a fixed ring.

[0008] The fixed ring is fixedly installed on the outer wall of the inclinometer probe, and the movable ring is slidably installed on the outer wall of the inclinometer probe. The movable ring is connected to the bottom of the fixed ring by a spring.

[0009] The traction assembly includes a traction rope and a pulley. The pulley is fixedly installed on the inclinometer probe. One end of the traction rope is fixedly installed below the movable ring, and the other end passes around the pulley, passes upward through the positioning tube, and then out of the movable ring.

[0010] The sliding assembly includes an upper limit block, a lower limit block, a slide rail, a slider, and a connecting rod. When the spring is in its natural state, the upper limit block is higher than the movable ring and is fixedly installed on the left outer wall of the inclinometer probe. The lower limit block is lower than the pulley and is fixedly installed on the left outer wall of the inclinometer probe. A slide rail is fixedly installed between the upper and lower limit blocks. The slider is slidably installed on the slide rail and connected to the movable ring. One end of the connecting rod is fixedly installed on the slider, and the other end is fixedly connected to the top of the curved shovel. The curved shovel is vertically positioned, and when the spring is in its natural state, the bottom of the curved shovel is located above the sliding wheel in the fully extended state of the inclinometer probe. When the traction rope is under tension, the spring stretches, the movable ring moves downward, and the slider on the slide rail moves downward along the slide rail. This causes the connecting rod connected to the slider and the curved shovel connected to the connecting rod to move downward together. The bottom of the curved shovel can then actuate the sliding wheel of the inclinometer probe, which is stuck in the inclinometer tube, causing the sliding wheel to retract.

[0011] The method for resolving the problem of the inclinometer probe getting stuck using the aforementioned traction and actuation mechanism is as follows:

[0012] Step 1: The operator installs the traction mechanism on the inclinometer probe, with each pulley equipped with a traction mechanism;

[0013] Step 2: The inclinometer probe is lowered into the inclinometer tube to measure the horizontal displacement of the support piles (walls);

[0014] Step 3: When the sliding wheel of the inclinometer probe gets stuck in the gap in the inclinometer tube, pull the traction rope. The movable ring and the slider move downwards. The spring is deformed by the tension. The slider drives the curved shovel downwards. The end of the curved shovel passes through the gap and moves the sliding wheel to disengage it from the gap in the inclinometer tube.

[0015] Step 4: The inclinometer probe continues to be lowered. After the sliding wheel passes through the gap, the traction rope is released, the spring returns to its original position, and the movable ring is pulled upward. The movable ring drives the curved shovel to move upward and return to its original position, thus solving the problem of the inclinometer probe getting stuck.

[0016] In the above technical solution, the fixing ring is fixedly installed on the outer wall of the inclinometer probe by screws.

[0017] In the above technical solution, the curved shovel is a long plate with a circular arc cross-section, with a length of 20cm and a thickness of 2mm. The circular arc cross-section of the curved shovel makes the profile of the sliding wheel of the inclinometer probe similar, which helps the curved shovel to move the sliding wheel.

[0018] In the above technical solution, when the spring deformation is 0, its length is 15cm.

[0019] In the above technical solution, the inclinometer probe is usually equipped with two sliding wheels, and each sliding wheel is equipped with a traction and actuation mechanism.

[0020] The advantages and beneficial effects of this invention are as follows:

[0021] When the inclinometer gets stuck in the gap in the inclinometer tube, the operator pulls the traction rope. The traction rope goes around the pulley and connects to the movable ring. The movable ring drives the curved shovel downwards. The curved shovel squeezes the sliding wheel of the inclinometer, allowing the sliding wheel to disengage from the gap. It then acts on the side surface of the curved shovel, effectively solving the problem of the inclinometer probe getting stuck in the inclinometer tube. When the inclinometer is measuring normally, the traction rope is released. Due to the spring action, the curved shovel is positioned above the sliding wheel of the inclinometer, without affecting the measurement results. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0029] A method for solving the problem of probe tube jamming in inclinometers is provided in the appendix. Figure 1 - Appendix Figure 3 The method involves setting a traction actuation mechanism on the inclinometer probe 13 to actuate the sliding wheel 16 of the inclinometer probe 13. The traction actuation mechanism includes: a traction component 1, a sliding component 2, a curved shovel 3, a spring 4, a movable ring 8, and a fixed ring 9.

[0030] The fixed ring 9 is fixedly installed on the outer wall of the inclinometer probe 13 by screws 14, and the movable ring 8 is slidably installed on the outer wall of the inclinometer probe 13. The movable ring 8 is connected to the lower part of the fixed ring 9 by spring 4.

[0031] The traction assembly includes a traction rope 6 and a pulley 7. The pulley 7 is fixedly installed on the inclinometer probe 13. One end of the traction rope 6 is fixedly installed below the movable ring 8, and the other end passes around the pulley 7, passes upward through the positioning tube 17, and then passes out of the movable ring 8.

[0032] The sliding assembly includes an upper limit block 10-1, a lower limit block 10-2, a slide rail 11, a slider 12, and a connecting rod 5. When the spring 4 is in its natural state, the upper limit block 10-1 is higher than the movable ring 8 and is fixedly installed on the left outer wall of the inclinometer probe 13. The lower limit block 10-2 is lower than the pulley 7 and is fixedly installed on the left outer wall of the inclinometer probe 13. The slide rail 11 is fixedly installed between the upper limit block 10-1 and the lower limit block 10-2. The slider 12 is slidably installed on the slide rail 11 and connected to the movable ring 8. One end of the connecting rod 5 is fixedly installed on the slide rail 11. The other end of the slider 12 is fixedly connected to the top of the curved shovel 3. The curved shovel 3 is set vertically. When the spring 4 is in its natural state, the bottom end of the curved shovel 3 is located above the sliding wheel 16 in the fully extended state of the inclinometer probe 13. When the traction rope 6 is pulled, the spring 4 is stretched, the movable ring 8 moves downward and drives the slider 12 on the slide 11 to move downward along the slide, so that the connecting rod 5 connected to the slider 12 and the curved shovel 3 connected to the connecting rod 5 move downward together. The bottom of the curved shovel 3 can then push the sliding wheel 16 of the inclinometer probe 13, which is stuck in the inclinometer tube 15, so that the sliding wheel 16 retracts.

[0033] Preferred options are listed in the appendix. Figure 4 and attached Figure 5 The curved shovel 3 is a long plate with a circular arc cross-section, with a length of 20cm and a thickness of 2mm. The circular arc cross-section of the curved shovel 3 makes the contour of the curved shovel 3 similar to that of the sliding wheel 16 of the inclinometer probe 13, which helps the curved shovel 3 to move the sliding wheel 16.

[0034] Furthermore, since the inclinometer probe 13 is usually equipped with two sliding wheels 16, each sliding wheel 16 is equipped with a traction actuation mechanism.

[0035] The method for resolving the problem of the inclinometer probe getting stuck using the aforementioned traction and actuation mechanism is as follows:

[0036] Step 1: The operator installs the traction mechanism on the inclinometer probe 13, and each sliding wheel 16 is equipped with a traction mechanism.

[0037] Step 2: Lower the inclinometer probe 13 into the inclinometer tube 15 (see appendix). Figure 1 ), to measure the horizontal displacement of the support piles (walls);

[0038] Step 3: When the sliding wheel 16 of the inclinometer probe 13 is stuck in the gap in the inclinometer tube 15, pull the traction rope 6, the movable ring 8 and the slider 12 move downward, the spring 4 is deformed by the tension, the slider 12 drives the curved shovel 3 to move downward, the end of the curved shovel 3 passes through the gap, and pushes the sliding wheel 16 to disengage from the gap in the inclinometer tube 15.

[0039] Step 4: The inclinometer probe 13 continues to be lowered. After the sliding wheel 16 passes through the gap, the traction rope 6 is released, the spring 4 returns to its original position, and the movable ring 8 is pulled upward. The movable ring 8 drives the curved shovel 3 to move upward and return to its original position, thus solving the problem of the inclinometer probe getting stuck.

[0040] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0041] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0042] The present invention has been described above by way of example. It should be noted that any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort without departing from the core of the present invention fall within the protection scope of the present invention.
