Description

Technical Field

[0001] This invention belongs to the technical field of height measuring devices, and specifically relates to a relative height measuring device. Background Technology

[0002] Existing height measuring devices are widely used in fields such as building construction, geological exploration, machinery manufacturing, and road construction. In building construction, traditional levels are used to measure floor elevations; in geological exploration, laser rangefinders are used to collect topographic elevation data; and in machinery manufacturing, dial indicators or vernier calipers are relied upon to detect the height of components.

[0003] Existing height measurement devices suffer from significant limitations: Low adjustment accuracy: Traditional mechanical height gauges rely on manual knob adjustments, lacking precise scale indications, resulting in an error rate as high as ±1mm, making it difficult to meet high-precision processing requirements. Complex and time-consuming operation: Leveling instruments require repeated tripod setup and manual leveling, with each measurement taking over 10 minutes, leading to low efficiency. Poor terrain adaptability: Rigid support structures are prone to tilting in soft soil or on slopes, causing measurement data distortion and requiring frequent adjustments or even equipment replacement. Limited functionality: Most devices only support single-dimensional measurements (such as horizontal or vertical), requiring multiple devices to work together, increasing operational complexity and cost. Insufficient stability: Existing tripod leg locking mechanisms are prone to loosening, and ground vibrations or external interference can easily cause measurement interruptions, resulting in low data reliability. For example, in construction, traditional levels require multiple repositionings in complex sites, delaying the construction period; in geological exploration, laser rangefinders suffer from data deviations due to unstable support in rugged terrain. These problems highlight the shortcomings of existing technologies in terms of high precision, high efficiency, and adaptability to complex environments. Summary of the Invention

[0004] To address the problems of low adjustment accuracy, complex and time-consuming operation, poor terrain adaptability, limited functionality, and insufficient stability of existing height measuring devices, this invention proposes a relative height measuring device.

[0005] Specifically, it includes: a mounting plate, the mounting plate having three mounting openings, and telescopic components hinged inside the three mounting openings for horizontal support of 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 inside of the mounting sleeve, a threaded hole is opened on the outer surface of the mounting sleeve, a fastening bolt is threaded into the inside of the threaded hole, 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 assembly includes a threaded rod, the outer surface of which is threadedly connected to the inside of a threaded sleeve; the threaded sleeve is provided with measuring scale lines; a vertical measuring device is provided on the threaded sleeve; a placement plate is fixedly installed at the bottom of the threaded rod, and a horizontal measuring device is fixedly installed at the top of the placement plate; the telescopic assembly includes a connecting rod hinged inside the mounting port, a telescopic rod slidably installed inside the connecting rod, and a support block is hinged to the bottom of the outer side of the telescopic rod; a second threaded hole is opened on the outer surface of the connecting rod, a threaded post is threadedly connected inside the second threaded hole, a rotating block is fixedly installed at one end of the threaded post, and the other end of the threaded post passes through the second threaded hole and extends to the outer surface of the telescopic rod; a placement assembly is provided at the top of the mounting plate; a leveling measuring device is clamped on the placement assembly.

[0007] According to the relative height measuring device described above, the placement component includes a mounting bracket fixedly connected to the upper surface of a mounting plate, 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, a first limiting block is slidably connected inside the first limiting groove, a second limiting block is slidably connected inside the second limiting groove, and a limiting shaft is rotatably connected inside the mounting plate.

[0009] According to the relative height measuring device described above, damping pads are fixedly connected to the outer sides of the first limiting block, the limiting shaft, and the second limiting block, and the three sets of damping pads are respectively attached to the first limiting groove, the mounting plate, and the second limiting 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 limiting block, and gears are hinged to both sides of the double-sided rack. The bottom of the gears is fixedly connected to one end of the limiting shaft, and a fixing frame is hinged to both sets of gears.

[0011] According to the relative height measuring device described above, the bottom of the fixed frame is fixedly connected to the upper surface of the second limiting block, and a sliding rod is installed on one side of one set of fixed frames, the sliding rod being slidably connected inside another set of fixed frames.

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

[0013] According to the above-described relative height measuring device, the leveling 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. This invention significantly improves measurement accuracy by utilizing the precise threaded fit between the threaded sleeve and the threaded rod, combined with a measuring scale and a vertical measuring device, achieving micron-level precision in height adjustment. In existing technologies, height adjustment often relies on visual inspection or simple mechanical limits, resulting in significant 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 levelness of the measurement reference. For example, the operator can directly read the fixed displacement of the scale line corresponding to each rotation of the threaded sleeve, avoiding human estimation errors and improving accuracy by more than 50% compared to traditional devices.

[0016] 2. The telescopic assembly of this invention adopts a combination design of hinged connecting rods and sliding telescopic rods, with quick locking via threaded posts, improving ease of operation and efficiency, reducing the device's unfolding and leveling time to 1 / 3 of traditional devices. Existing technology requires manual adjustment of each tripod leg, which is time-consuming and labor-intensive; however, this device, through the linkage structure of the sliding sleeve and support rod, can simultaneously adjust the length of three sets of telescopic rods, and fix them with a single click using fastening bolts, greatly simplifying the operation process, and is especially suitable for measurement scenarios involving frequent movement.

[0017] 3. The bottom of the support block in this invention features a damping pad design that fits tightly against the first and second limiting grooves, effectively absorbing ground vibrations and enhancing structural stability and adaptability. Existing rigid support structures are prone to settling on soft soil foundations, leading to inaccurate measurements. This invention's three sets of telescopic components are independently hinged, adapting to ground undulations. Combined with a double-sided rack and pinion locking mechanism, it ensures the mounting plate remains horizontal at all times. Experiments show that this device remains stable even on terrain with a slope ≤15°, significantly expanding its applicability.

[0018] 4. The horizontal measuring device, vertical measuring device, and leveling device of this invention are integrated on the same platform, replacing the traditional multi-device collaborative mode. This multi-functional integration reduces overall costs. Existing technologies require the separate purchase of equipment such as levels and distance measuring instruments, which is costly and involves complex data integration. This device uses a unified mounting component to clamp the optical level and utilizes the mounting bracket's limiting slots to achieve rapid switching. Horizontal, vertical, and relative height data can be obtained in a single measurement, reducing equipment purchase and maintenance costs by approximately 40%.

[0019] 5. The device of this invention is made of lightweight aluminum alloy and reduces redundant parts through the reuse design of sliding sleeve and fixed sleeve, thus saving energy and protecting the environment. Traditional measuring devices are bulky and consume a lot of energy during transportation, while this device reduces the total weight by 30%, and the telescopic rod is retractable and adjustable, avoiding frequent replacement of consumables. In addition, the standardized design of the threaded sleeve and threaded rod facilitates mass production, increases the utilization rate of raw materials by 20%, and conforms to the trend of green manufacturing.

[0028] The placement component 51 includes a mounting bracket 14 fixedly connected to the upper surface of the mounting plate 1, and the mounting plate 1 is provided with a first limiting groove 15 and a second limiting groove 18.

[0029] The first limiting groove 15 is slidably connected to the first limiting block 16, the second limiting groove 18 is slidably connected to the second limiting block 19, and the mounting plate 1 is rotatably connected to the limiting shaft 17.

[0030] Damping pads are fixedly connected to the outer sides of the first limiting block 16, the limiting shaft 17, and the second limiting block 19. The three sets of damping pads are respectively attached to the first limiting groove 15, the mounting plate 1, and the second limiting groove 18.

[0031] A double-sided rack 20 is fixedly connected to the upper surface of the first limiting block 16. Gears 24 are hinged to both sides of the double-sided rack 20. The bottom of the gears 24 is fixedly connected to one end of the limiting shaft 17. Fixing brackets 25 are hinged to both sets of gears 24.

[0032] The bottom of the fixing frame 25 is fixedly connected to the upper surface of the second limiting block 19. A sliding rod 26 is installed on one side of one set of fixing frames 25, and the sliding rod 26 is slidably connected to the inside of another set of fixing frames 25.

Telescopic component 12: composed of a hinged connecting rod 101, a telescopic rod 102, and a support block 103, with anti-slip texture on the bottom of the support block. Placement component 51: includes a mounting frame 14, a first limiting groove 15, a second limiting groove 18, and a double-sided rack 20, used to fix the optical level. Sliding sleeve 6: an externally hinged support connecting rod 61, whose position is adjusted to achieve support angle compensation. Embodiments of the present invention:

[0036] 1. Assembly and initial leveling of the device

[0037] Place the mounting plate 1 in the area to be tested, and unfold the three sets of telescopic components 12: loosen the rotating block at the end of the threaded column 102, pull out the telescopic rod 102 to the required length, and then lock it. After the support block 103 contacts the ground, manually fine-tune the length of the telescopic rod 102 by observing the reading of the level measuring device 600 to make the mounting plate 1 initially level.

[0038] 2. Precision height adjustment

[0039] Rotate the threaded sleeve 21 to move the threaded rod 201 up and down vertically. The amount of movement is precisely controlled by measuring the scale 501, with each division corresponding to 0.1mm. Simultaneously, observe the verticality indicator on the vertical measuring device 500 to ensure the threaded rod 201 is not skewed. Once the placement plate 202 reaches the target height, tighten the fastening bolt 22 to fix the relative position of the threaded sleeve 21 and the mounting sleeve 2.

[0040] 3. Leveling and Data Integration

[0041] The optical level is clamped onto the mounting bracket 14 of the placement component 51. The first limiting block 16 and the second limiting block 19 are slid to the designated positions of the first limiting groove 15 and the second limiting groove 18, and locked by the limiting shaft 17. The optical level is then started to measure the relative height of the target point. The meshing structure of the double-sided rack 20 and the gear 24 prevents the instrument from slipping and ensures measurement stability.

[0042] 4. Linkage adjustment of supporting structure

[0043] If uneven ground causes instability on one side of the support, the sliding sleeve 6 can be adjusted to move up and down along the threaded sleeve 21, driving the support connecting rod 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, ultimately restoring the mounting plate 1 to a horizontal state.

[0044] 5. Disassembly and Maintenance

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

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

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
