Abstract
Description
Technical Field
[0001] This invention relates to the field of engineering construction testing technology, and more specifically, to a tilt measuring lifting drive mechanism and method. Background Technology
[0002] In engineering, inclinometers, which are used to monitor changes in soil displacement, are divided into portable inclinometers and fixed inclinometers.
[0003] An existing portable inclinometer includes a movable probe, a dedicated cable, a reader, and data communication processing software. The movable probe is connected to the reader via the dedicated cable, which is used to raise and lower the probe. Data is typically measured when the probe is raised, with data read and recorded every half meter. After measuring the entire inclinometer tube, the probe is rotated 180° and the measurement is repeated in the opposite direction. The raising, lowering, and reversing operation of the movable probe in this portable inclinometer involves manual operation via a cable of several tens of meters. Guide wheels on the movable probe, matching the guide groove on the inner wall of the inclinometer tube, allow the probe to rise or fall along the guide groove. When a 180° rotation is needed, the probe is pulled out of the inclinometer tube, rotated 180°, and then lowered back into the inclinometer tube. This operation is extremely cumbersome. Furthermore, human error significantly affects measurement accuracy. Existing fixed inclinometers have their transmission mechanism external to the inclinometer tube, resulting in large dimensions that obstruct the passage of other equipment on the construction site and prevent measurements in the reverse direction after the movable probe has been reversed.
[0004] To address the aforementioned issues, we designed an inclinometer comprising a movable probe, a lifting cable, a support cylinder, a fixed base, a fixed column, an inclinometer steering drive mechanism, and an inclinometer lifting drive mechanism. The movable probe is equipped with a guide wheel assembly that matches the guide groove on the inner wall of the inclinometer guide tube. The top of the support cylinder is fitted into the fixed base, and the inclinometer steering drive mechanism drives the support cylinder to rotate. The inclinometer lifting drive mechanism is installed inside the support cylinder. The fixed column is located below the support cylinder, and its top is equipped with a driven wheel. The movable probe is located between the inclinometer lifting drive mechanism and the fixed column. The inclinometer lifting drive mechanism drives the lifting cable to move, allowing the movable probe to move up and down. The inner wall of the support cylinder is provided with guide grooves that match the guide groove on the inner wall of the inclinometer guide tube, used to limit and guide the guide wheel assembly. This inclinometer improves the accuracy, efficiency, and reliability of inclination measurement, contributing to improved quality and safety in engineering construction.
[0005] The inclinometer we designed above is prone to slippage when the lifting cable is running, especially when it encounters groundwater, resulting in large measurement errors. In addition, if the slippage lasts for a slightly longer period of time, the system needs to remeasure, which may lead to infinite repeated measurements without necessarily obtaining relatively reliable results. The lifting cable also experiences relatively large wear and tear, requiring frequent replacements and resulting in high operating costs. Summary of the Invention
[0006] The present invention provides a tilt-measuring lifting drive mechanism and method, which can solve the above-mentioned problems.
[0007] To solve the above problems, the technical solution adopted by the present invention is as follows:
[0008] In a first aspect, the present invention provides a tilting and lifting drive mechanism, including a lifting cable, a base for fixing inside a bearing cylinder, and a drive wheel assembly and a power device installed on the base. The lifting cable has two ends, with the first end for connecting to the upper end of the movable probe and the second end for connecting vertically upward to the lower end of the movable probe after passing over the guide wheel at the top of the fixed column. The drive wheel assembly includes a gear set rotatably mounted on the base, an upper drive wheel, a lower drive wheel, and a guide wheel assembly, and the axles of each wheel are arranged in the left-right direction.

[0011] Each of the lower and upper wheel grooves is fitted with a portion of the lifting cable, and the portion of each groove wrapped by the lifting cable is less than one full turn; from left to right, the lifting cable changes direction after passing the nth lower wheel groove, changes direction after passing the nth upper wheel groove, then changes direction after passing the (n+1)th lower wheel groove, and then changes direction after passing the (n+1)th upper wheel groove, where the (n+1)th lower wheel groove is not the leftmost lower wheel groove; the portion of the lifting cable between the upper and lower drive wheels forms a cross-layout arrangement with equal distances from left to right;
[0012] The upper part of the first end of the lifting cable first passes around the rightmost lower wheel groove, and then passes around the other upper and lower wheel grooves; the upper part of the second end of the lifting cable first passes around the leftmost lower wheel groove, and then passes around the other upper and lower wheel grooves.
[0013] The guide wheel assembly is located below the lower drive wheel and is used to guide the lifting cable to move along the length of the cable.
[0014] In a preferred embodiment of the present invention, the gear set is provided with a torque input shaft connected to the rotation output shaft of the power device, and two torque output shafts whose rotation directions are only opposite to each other. The two torque output shafts are the wheel axles of the upper drive wheel and the lower drive wheel, respectively.

[0016] In a preferred embodiment of the present invention, there are four lower wheel grooves, which are arranged from left to right as a first lower wheel groove, a second lower wheel groove, a third lower wheel groove, and a fourth lower wheel groove; there are three upper wheel grooves, which are arranged from left to right as a first upper wheel groove, a second upper wheel groove, and a third upper wheel groove; and from left to right, the lifting cable is arranged in the following order around the wheel grooves as a first lower wheel groove, a first upper wheel groove, a second lower wheel groove, a second upper wheel groove, a third lower wheel groove, a third upper wheel groove, and a fourth lower wheel groove.
[0017] In a preferred embodiment of the present invention, the drive wheel assembly further includes a pressure wheel assembly rotatably mounted on the base and with the wheel axle arranged in the left-right direction. The pressure wheel assembly presses down on the top of the upper drive wheel to prevent the lifting cable from disengaging from the upper wheel groove.
[0018] In a preferred embodiment of the present invention, the guide wheel assembly includes a first guide wheel, a second guide wheel, a first guide wheel, a second guide wheel, and a third guide wheel; the front wheel surface of the first guide wheel contacts the rear wheel surface of the second guide wheel; the first guide wheel, the second guide wheel, and the third guide wheel are mounted on the same horizontal plane below the guide wheel, the first guide wheel and the third guide wheel share a common axle, and the rear wheel surface of the second guide wheel contacts the front wheel surface of the third guide wheel;
[0019] The first guide roller is provided with a first left positive annular guide rope groove, a first right positive annular guide rope groove, and a first pressing rope section located between the first left positive annular guide rope groove and the first right positive annular guide rope groove; the second guide roller is provided with a second left positive annular guide rope groove, a second right positive annular guide rope groove, and a second pressing rope section located between the second left positive annular guide rope groove and the second right positive annular guide rope groove.
[0020] The first and second rope pressing sections press against the other lower wheel grooves except for the leftmost and rightmost lower wheel grooves;
[0021] The first end of the lifting cable passes from top to bottom between the first right positive annular guide groove and the second right positive annular guide groove, and between the second guide wheel and the third guide wheel, before being connected to the upper end of the movable probe.

[0024] In a preferred embodiment of the present invention, the number of lower wheel grooves is one more than the number of upper wheel grooves.
[0025] Secondly, the present invention provides a method for driving the inclinometer lifting mechanism, which adopts the inclinometer lifting mechanism described in the first aspect. The first end of the lifting cable is connected to the upper end of the movable probe, and the second end is connected vertically upward to the lower end of the movable probe after passing over the guide wheel at the top of the fixed column. The power device drives the upper drive wheel and the lower drive wheel to rotate through the gear set, thereby realizing the movement of the lifting cable along the length of the cable, so that the movable probe can perform lifting and lowering actions.
[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] (1) Both the upper drive wheel and the lower drive wheel are equipped with wheel grooves that wrap around the lifting cable. By repeatedly winding up and down, the friction between the lifting cable and the drive wheel is increased, thereby ensuring that the lifting cable moves stably along the length of the cable through the drive wheel, and then driving the movable probe to achieve stable and reliable lifting motion, avoiding slippage that leads to measurement errors.
[0028] (2) The number difference between the upper and lower wheel grooves was limited, and the layout of the upper wheel groove relative to the lower wheel groove was staggered to facilitate the repeated winding of the lifting cable.
[0029] (3) The lifting cable and the movable probe form a closed loop structure. While ensuring that the lifting cable can drive the movable probe to move up and down, the amount of lifting cable used is greatly reduced, making operation more convenient and reducing wear.
