Description

Technical Field

[0001] The present invention belongs to the technical field of height measuring devices, and in particular relates to a relative height measuring device. Background Art

[0002] Existing height measurement devices are widely used in construction, geological exploration, machinery manufacturing, and road construction. In construction, traditional levels are used to measure floor elevations; in geological exploration, laser rangefinders are used to collect terrain elevation data; and in machinery manufacturing, micrometers or vernier calipers are used to measure component heights.

[0003] Existing height measurement devices have significant limitations: Low adjustment accuracy: Traditional mechanical altimeters rely on manual knob adjustment and lack precise scale indication, resulting in an error rate as high as ±1mm, making them difficult to meet the requirements of high-precision machining. Complex and time-consuming operation: Levels require repeated tripod setup and manual leveling, taking over 10 minutes per measurement, resulting in low efficiency. Poor terrain adaptability: Rigid support structures can easily tilt on soft soil or slopes, resulting in distorted measurement data and requiring frequent adjustments or even replacement of equipment. Single-function: Most devices only support single-dimensional measurement (such as horizontal or vertical), requiring the coordinated operation of multiple devices, increasing operational complexity and cost. Insufficient stability: Existing tripod leg locking mechanisms are prone to loosening, and ground vibrations or external interference can easily interrupt measurements, resulting in low data reliability. For example, in construction, traditional levels require multiple repositionings in complex sites, delaying construction schedules. In geological exploration, laser rangefinders in rugged terrain suffer from unstable support, leading to data deviations. These issues highlight the limitations of existing technologies in terms of high precision, high performance, and adaptability to complex environments. Summary of the Invention

[0004] In order to solve the problems of low adjustment accuracy, complex and time-consuming operation, poor terrain adaptability, single function and insufficient stability of the height measuring device in the prior art, the present invention proposes a relative height measuring device.

[0005] Specifically comprising: a mounting plate, the mounting plate having three mounting openings, the interior of the three mounting openings being hinged with telescopic components for horizontally supporting the mounting plate, characterized in that: a mounting sleeve is fixedly mounted on the bottom of the mounting plate, a threaded sleeve is inserted into the interior of the mounting sleeve, a threaded hole 1 is formed on the outer surface of the mounting sleeve, a fastening bolt is connected to the inner thread of the threaded hole 1, one end of the fastening bolt passes through the mounting sleeve and the threaded sleeve and extends to the outside of the other side of the mounting sleeve, and a horizontal component is mounted on the bottom of the threaded sleeve;

[0006] The horizontal component includes a threaded rod, the outer surface of which is threadedly connected to the inside of a threaded sleeve; a measuring scale line is provided on the threaded sleeve; a vertical measuring device is provided on the threaded sleeve; a placing plate is fixedly installed at the bottom of the threaded rod, and a horizontal measuring device is fixed on the top of the placing plate; the telescopic component includes a connecting rod hinged inside the mounting port, a telescopic rod is slidably installed inside the connecting rod, and a support block is hinged at the bottom outside the telescopic rod; a threaded hole 2 is provided on the outer surface of the connecting rod, a threaded column is threadedly connected to the inside of the threaded hole 2, a rotating block is fixedly installed on one end of the threaded column, and the other end of the threaded column passes through the threaded hole 2 and extends to the outer surface of the telescopic rod; a placing component is provided on the top of the mounting plate; and a leveling device is clamped on the placing component.

[0007] According to the relative height measuring device described above, the placement component includes a mounting plate with a mounting frame fixedly connected to its upper surface, and the mounting plate is provided with a first limiting groove and a second limiting groove.

[0008] According to the relative height measuring device described above, the first limiting groove is internally slidably connected to a first limiting block, the second limiting groove is internally slidably connected to a second limiting block, and the mounting plate is internally rotatably connected to a limiting shaft.

[0009] According to the relative height measuring device described above, the outer sides of the first limit block, the limit shaft and the second limit block are fixedly connected with damping pads, and the three groups of damping pads are respectively attached to the first limit groove, the mounting plate and the second limit groove.

[0010] According to the relative height measuring device described above, a double-sided rack is fixedly connected to the upper surface of the first limit block, gears are hinged on both sides of the double-sided rack, the bottom of the gear is fixedly connected to one end of the limit shaft, and a fixing frame is hinged on both groups of the gears.

[0011] According to the relative height measuring device described above, the bottom of the fixing frame is fixedly connected to the upper surface of the second limit block, and a sliding rod is installed on one side of one group of the fixing frames, and the sliding rod is slidably connected to the inside of the other group of fixing frames.

[0012] According to the relative height measuring device described above, the outer surface of the threaded sleeve is sleeved with a sliding sleeve, the outer surface of the sliding sleeve is hinged with a supporting connecting rod, the other end of the supporting connecting rod is hinged with a fixed sleeve, and the fixed sleeve is fixedly sleeved on the outer surface of the connecting rod.

[0013] According to the relative height measuring device described above, the leveling measuring device is an optical level; the horizontal measuring device is an infrared level; and the vertical measuring device is a vertical detector.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention significantly improves measurement accuracy by matching the precise threads of the threaded sleeve and the threaded rod, combined with measuring scale lines and a vertical measuring device, and achieves micron-level precision in height adjustment. In the prior art, height adjustment mostly relies on visual inspection or simple mechanical limits, which results in large errors. This device quantifies the adjustment distance through scale lines and uses a vertical measuring device to provide real-time feedback on verticality, ensuring the absolute level of the measurement reference. For example, each rotation of the threaded sleeve corresponds to a fixed displacement of the scale line. The operator can directly read the value, avoiding human estimation errors, and the accuracy is improved by more than 50% compared to traditional devices.

[0016] 2. The telescopic assembly of this invention utilizes a combination of an articulated connecting rod and a sliding telescopic rod, coupled with a threaded post for quick locking, improving operational convenience and efficiency, reducing deployment and leveling time to one-third of conventional systems. While existing technologies require manual adjustment of tripod legs individually, which is time-consuming and labor-intensive, this device, through the linkage of a sliding sleeve and supporting connecting rod, allows for simultaneous adjustment of the length of the three telescopic rods, which can be secured with a single bolt. This significantly simplifies operation and is particularly suitable for frequently mobile measurement scenarios.

[0017] 3. The bottom of the support block of the present invention adopts a damping pad design, which fits tightly with the first limit groove and the second limit groove, effectively absorbing ground vibrations, and enhancing structural stability and adaptability. The rigid support structure of the existing device is prone to sinking on soft soil foundations, resulting in inaccurate measurements. The three groups of telescopic components of the present invention are independently hinged and can adapt to the undulations of the ground. The meshing and locking mechanism of the double-sided rack and gear ensures that the mounting plate is always in a horizontal state. Experiments have shown that the device can still remain stable in terrain with a slope of ≤15°, and its scope of application has been significantly expanded.

[0018] 4. The horizontal measuring device, vertical measuring device and leveling measuring device of the present invention are integrated into the same platform, replacing the traditional multi-device collaboration mode. The multi-functional integration reduces the overall cost. The existing technology requires the separate purchase of equipment such as spirit levels and rangefinders, which is costly and complex to integrate data. This device uniformly clamps the optical level by placing components and uses the limit slots of the mounting frame to achieve rapid switching. A single measurement can obtain horizontal, vertical and relative height data, reducing equipment purchase and maintenance costs by approximately 40%.

[0019] 5. The device is constructed of lightweight aluminum alloy and utilizes a reusable sliding sleeve and fixed sleeve, reducing redundant components and maximizing energy conservation and environmental protection. While conventional measuring devices are bulky and require high transportation energy, this device is 30% lighter, and the retractable and adjustable telescopic rod eliminates the need for frequent consumable replacement. Furthermore, the standardized design of the threaded sleeve and rod facilitates mass production, increasing raw material utilization by 20%, in line with green manufacturing trends.

A sliding sleeve 6: an externally articulated support link 61, and support angle compensation is achieved by adjusting its position. Embodiments of the present invention:

[0036] 1. Device assembly and initial leveling

[0037] Place the mounting plate 1 in the area to be measured and deploy the three telescopic components 12. Unscrew the rotating block at the end of the threaded post 102, extend the telescopic rod 102 to the desired length, and then tighten it. After the support block 103 touches the ground, manually fine-tune the length of the telescopic rod 102 by observing the reading of the leveling device 600 to initially level the mounting plate 1.

[0038] 2. Precision height adjustment

[0039] Rotate the threaded sleeve 21, moving the threaded rod 201 vertically upward or downward. Use the measuring scale 501 to precisely control the amount of lift, with each scale corresponding to 0.1 mm. Simultaneously, observe the verticality indicator on the vertical measuring device 500 to ensure that the threaded rod 201 is not tilted. When the placement plate 202 reaches the target height, tighten the fastening bolts 22 to secure the relative position of the threaded sleeve 21 and the mounting sleeve 2.

[0040] 3. Leveling and data integration

[0041] Clamp the optical level to the mounting bracket 14 of the placement assembly 51. Slide the first and second stop blocks 16 and 19 to the designated positions of the first and second stop slots 15 and 18, and lock them with the stop shaft 17. Activate the optical level and measure the relative height of the target point. The meshing structure of the double-sided rack 20 and gear 24 prevents the instrument from slipping, ensuring measurement stability.

[0042] 4. Support structure linkage adjustment

[0043] If the ground is uneven and the support on one side is unstable, the sliding sleeve 6 can be adjusted to move up and down along the threaded sleeve 21, driving the supporting link 61 to push the fixed sleeve 62, thereby changing the tilt angle of the connecting rod 101. This process achieves adaptive compensation through the sliding of the sliding rod 26 within the fixed frame 25, and ultimately restores the mounting plate 1 to a horizontal state.

[0044] 5. Disassembly and maintenance

[0045] After completing the measurement, loosen the fastening bolts 22 and threaded column 102, retract the telescopic rod 102 into the connecting rod 101, and fold the supporting link 61. The optical level can be quickly removed from the mounting bracket 14. The surface of the damping pad can be cleaned with a soft cloth. Regularly check the thread wear of the threaded sleeve 21 and the threaded rod 201, and apply grease if necessary.

[0046] This implementation method ensures the efficiency and reliability of the device through modular design and linkage adjustment mechanism, and is suitable for precision engineering measurements in complex environments.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
