TECHNICAL FIELD
[0001] The utility model relates to the technical field of slope ruler, especially a slope ruler for engineering detection. BACKGROUND
[0002] In the field of engineering survey, slope measurement is a basic and key work, and its accuracy is directly related to the quality and safety of various projects. The slope ruler in the prior art represented by the MNT1111804 type slope measurement ruler has many limitations in actual application.
[0003] The MNT1111804 type slope measurement ruler mainly relies on the rotation of the knob to adjust the position of the level bubble tube to achieve horizontal placement and slope measurement. This operation method has obvious drawbacks. On the one hand, the operation process relies on manual fine adjustment, and the measurement personnel need to repeatedly rotate the knob, rely on experience and naked eye observation of the position of the bubble in the level bubble tube, and the operation process is extremely tedious and time-consuming. For example, in large-scale road construction projects, the slope of a large number of road sections needs to be measured, and this manual operation method will greatly reduce the work efficiency and increase the measurement cost. On the other hand, human operation inevitably introduces errors, and the operation habits and proficiency of different measurement personnel, as well as fatigue caused by long-time operation, may cause the adjustment of the level bubble tube to be not accurate enough, thereby affecting the accuracy of the slope measurement. Once the measurement error exceeds the allowable range of the project, it may cause serious consequences such as poor road drainage and unstable building foundation.
[0004] In addition, when the working environment is complex, such as narrow space, dim light, or large vibration interference, the operator is difficult to accurately operate the knob, further reducing the reliability of the measurement. Moreover, such slope rulers have single function and can only rely on manual knob operation, lacking a backup adjustment mechanism to deal with unexpected situations. Once the level bubble tube cannot be adjusted to the horizontal state by the knob, such as damage to the knob mechanism or jamming due to long-term use, the measurement work will be stalled, seriously affecting the project progress. In view of this, we propose a slope ruler for engineering detection. UTILITY MODEL CONTENT
[0005] The main purpose of the utility model is to provide a slope ruler for engineering detection, which can effectively solve the problems in the background art.
[0006] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:
[0007] The utility model provides a kind of engineering detects with slope ruler, including shell, annular turntable and level bubble tube, the shell is provided with round hole, the periphery of round hole in the shell is provided with first slope scale, the level bubble tube is symmetrically installed in the inner circle of annular turntable, the pointer for pointing to first slope scale is installed on the both sides of annular turntable, the counterweight is embeddedly installed on the side of annular turntable away from pointer, the line of connection of counterweight and pointer and the central axis of level bubble tube vertical intersection, two big bearings are coaxially connected between the outer wall of annular turntable and the inner wall of round hole;
[0008] The periphery of annular turntable is coaxially fixedly installed with outer wheel, one end of counterweight is embeddedly installed in outer wheel, the side of shell is telescopically rotatably connected with rotation twist by damping pivot, the inner side of rotation twist is coaxially connected with rubber wheel, and the outer wheel and rubber wheel are closedly installed in shell, and the outer circle of outer wheel and rubber wheel is extruded each other.
[0009] Preferably, the outer surface of the outer wheel is connected with a non-slip leather sheath, and the outer surface of the non-slip leather sheath is provided with a straight-line non-slip pattern.
[0010] Preferably, one end of the shell is rotatably connected with a cylinder through a small bearing, the surface of the cylinder is provided with a second slope scale, and the outer circle of the cylinder and the non-slip leather sheath is extruded each other.
[0011] Preferably, the cylinder is arranged in the shell, and an observation window is arranged on the side outer wall of the shell opposite to the cylinder.
[0012] Preferably, a transparent glass is fixedly installed in the observation window.
[0013] Preferably, the edge of the rubber wheel away from the rotation twist is provided with a chamfer.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. The measurement efficiency is greatly improved: the counterweight gravity automatic leveling mechanism is adopted, and the level bubble tube does not need to be repeatedly operated by manual rotation twist to adjust the level bubble tube; in various engineering measurement scenes, the level bubble tube can be quickly leveled to obtain slope data, and the measurement time is greatly shortened; compared with the traditional manual adjustment mode, the work efficiency can be improved by several times or even dozens of times, the engineering progress is effectively accelerated, and the time cost is reduced.
[0016] 2. The measurement accuracy is significantly improved: the automatic leveling is based on the stable gravity of the counterweight, which avoids the uncertainty and error caused by manual operation of the rotation twist; the measurement result is more stable and accurate, and the precision deviation caused by the operation difference of the measurement personnel is reduced.
[0017] 3. Enhanced operation adaptability: In complex environments such as narrow spaces, insufficient light, or vibration environment, the traditional slope ruler operation is difficult, while the automatic leveling function of the slope ruler is not affected by these factors and can still work reliably. Even in a corner of the construction site filled with building materials, dim light, or an area surrounded by large machinery operation generating vibration, the slope can still be accurately measured.
[0018] 4. Flexible adjustment mode: When the automatic leveling function fails, it can be easily switched to manual operation mode. By pressing the knob, the knob can be adjusted by squeezing the rubber wheel and the outer wheel, and the angle of the annular turntable can be adjusted to manually adjust the level tube. This backup adjustment mechanism provides double protection for measurement work, ensuring smooth slope measurement regardless of unexpected situations, avoiding project delays due to equipment failure, and greatly improving the practicality and reliability of the slope ruler in various complex working conditions.
[0019] 5. Optimized reading experience: The second scale is set on the top, breaking the limitation of traditional slope rulers with scales only on the side. During measurement, especially when the slope ruler is placed in a poor position, such as measuring the slope of a river channel with the shell on the ground, the measurement personnel do not need to bend over to read the side scale. The second slope scale is read directly from above, with a more natural and comfortable viewing angle, greatly improving the convenience of reading. At the same time, it reduces visual errors caused by poor reading angles, further improves the accuracy of measurement data reading, and makes slope measurement more efficient and accurate.
