Description

Technical Field

[0001] This utility model belongs to the field of pulleys, specifically relating to a special pulley for a deep horizontal displacement monitoring inclinometer. Background Technology

[0002] In deep horizontal displacement monitoring and measurement, inclinometers are commonly used. Inclinometers come with manual tension probes, and in recent years, newer models with automatic tension probes have been developed for monitoring during construction.

[0003] Existing devices are often affected by site conditions and backfilling construction, making it impossible to use automated monitoring equipment and forcing the use of manual inclinometers with manually stretched probes. Utility Model Content

[0004] To overcome the problem that existing devices are often affected by site conditions and backfilling construction, and cannot use automated monitoring equipment, but can only use manual pulling probes, a special pulley for deep horizontal displacement monitoring inclinometers is proposed.

[0005] The technical solution of this utility model is: a special pulley for a deep horizontal displacement monitoring inclinometer, including a tapered tube and a sliding mechanism set at the upper end of the tapered tube, a limit mechanism set on both sides of the tapered tube, a handle fixedly connected to both sides of the sliding mechanism, and a scale opened on one side of the sliding mechanism.

[0006] Furthermore, the sliding mechanism includes fixed blocks fixed to the upper ends of both sides of the tapered tube, a pulley body fixed to the side of the two fixed blocks that are close to each other, and a blocking block fixed to the side of the two fixed blocks that are far apart from each other.

[0007] Furthermore, the limiting mechanism includes limiting blocks fixed to both sides of the tapered tube. A first slot is provided on one side of the limiting block. One end of a spring is fixed to the inner wall of the first slot. A rotating block is rotatably installed on the inner wall of the first slot. The other end of the spring is in contact with one side of the rotating block.

[0008] Furthermore, a handle is fixedly attached to the side of the two fixed blocks away from the pulley body.

[0009] Furthermore, a scale is provided on the side wall of the fixing block on one side of the tapered tube.

[0010] Furthermore, a through hole is provided on one side of the tapered tube.

[0011] Furthermore, the fixing block and the pulley body are connected by bolts.

[0012] The beneficial effects of this utility model are as follows: By using the structural design of squeezing the rotating block, spring deformation, and the rotating block being inserted into the first slot of the limiting block and aligned with the groove on the inner wall of the inclinometer tube, the problem of inaccurate alignment and unstable fixation between the device and the inclinometer tube is solved. This ensures that the device is stably installed inside the inclinometer tube, avoiding errors caused by loosening during measurement. The scale on the side wall of the fixing block provides a clear benchmark for the initial position of the measuring rope, solving the problems of inconsistent measurement benchmarks and large data errors caused by the lack of a unified reference for the initial position of the measuring rope and the large degree of arbitrariness in adjustment in traditional operations. Through the design of the handle stabilizing device, the operator can fix the device with one hand and operate the measuring rope with the other hand, solving the problem of easy shaking and difficulty in stable control of the device during measurement. This ensures that the inclinometer probe rises and falls smoothly along the inclinometer tube, reducing measurement deviations or equipment damage caused by shaking. Utilizing the elastic deformation characteristics of the spring, when the device is removed, the side wall of the inclinometer tube squeezes the rotating block, causing the spring to contract. This avoids the problems of jamming, difficult operation, or even damage to the inclinometer tube or device caused by excessive tightness in traditional fixing structures.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-5 This utility model provides an embodiment of a special pulley for a deep horizontal displacement monitoring inclinometer, which includes a tapered tube 1 and a sliding mechanism 2 provided at the upper end of the tapered tube 1. Limiting mechanisms 3 are provided on both sides of the tapered tube 1. Handles 4 are fixedly connected to both sides of the sliding mechanism 2. A scale 5 is provided on one side of the sliding mechanism 2.

[0021] In use, first, by squeezing the rotating block 34, the rotating block 34 squeezes the spring 33, pressing the rotating block 34 against the inner wall of the first slot 32 of the limiting block 31, and then aligning it with the groove on the inner wall of the inclinometer tube. The conical tube 1 is then placed inside the inclinometer tube. The measuring rope of the inclinometer is passed around the pulley body 22 at the top. The scale 5 on the side wall of the fixing block 21 is observed, and the initial position of the measuring rope is adjusted so that it is aligned with the zero mark or the preset reference mark on the scale 5. Then, the operator holds the handle 4 with one hand to stabilize the device and pulls the measuring rope with the other hand to make the inclinometer probe descend or rise along the inside of the inclinometer tube. After the test is completed, the operator holds the handle 4 and pulls upward to remove the conical tube 1 from the inside of the inclinometer tube. The side wall of the inclinometer tube squeezes the rotating block 34, and the rotating block 34 squeezes the spring 33, making it easy to remove the device.

[0022] Please see Figure 4 In this embodiment, the sliding mechanism 2 includes fixed blocks 21 fixed to the upper ends of both sides of the tapered tube 1. The pulley body 22 is fixed to the side of the two fixed blocks 21 that are close to each other. The blocking blocks 23 are fixed to the side of the two fixed blocks 21 that are far apart from each other. The blocking blocks 23 prevent the device from falling into the inclinometer tube.

[0023] Please see Figure 5 In this embodiment, the limiting mechanism 3 includes a limiting block 31 fixed to both sides of the tapered tube 1. A first slot 32 is provided on one side of the limiting block 31. One end of a spring 33 is fixed to the inner wall of the first slot 32. A rotating block 34 is rotatably installed on the inner wall of the first slot 32. The other end of the spring 33 is in contact with one side of the rotating block 34. The inner wall of the inclinometer tube squeezes the rotating block 34, and the rotating block 34 squeezes the spring 33, increasing the friction between the rotating block 34 and the inner wall of the inclinometer tube.

[0024] Please see Figure 4 In this embodiment, the two fixing blocks 21 are jointly fixed with a handle 4 on the side away from the pulley body 22, which makes it convenient for the operator to carry and move the device.

[0025] Please see Figure 4 In this embodiment, a scale 5 is provided on the side wall of the fixing block 21 on one side of the tapered tube 1, which facilitates the control of the measuring rope position.

[0026] Please see Figure 1 In this embodiment, a through hole is provided on one side of the tapered tube 1, and the lower end of the tapered tube 1 can extend into the inclinometer tube to form a stable structure. The through hole allows the tapered tube 1 to adapt to inclinometer tubes of different sizes.

[0027] Please see Figure 4 In this embodiment, the fixing block 21 and the pulley body 22 are connected by bolts, which facilitates installation and disassembly.

[0028] Working principle: First, by squeezing the rotating block 34, the rotating block 34 squeezes the spring 33, pressing the rotating block 34 against the inner wall of the first slot 32 of the limiting block 31, and then aligning it with the groove on the inner wall of the inclinometer tube. The conical tube 1 is then placed inside the inclinometer tube. The measuring rope of the inclinometer is passed around the pulley body 22 at the top. The scale 5 on the side wall of the fixed block 21 is observed, and the initial position of the measuring rope is adjusted so that it is aligned with the zero mark or the preset reference mark on the scale 5. Then, the operator holds the handle 4 with one hand to stabilize the device and pulls the measuring rope with the other hand, so that the inclinometer probe descends or rises along the inside of the inclinometer tube. After the test is completed, the operator holds the handle 4 and pulls upward to remove the conical tube 1 from the inside of the inclinometer tube. The side wall of the inclinometer tube squeezes the rotating block 34, and the rotating block 34 squeezes the spring 33, making it easy to remove the device.
