Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically a measuring device for road mechanical engineering. Background Technology

[0002] With the continuous and rapid development of infrastructure construction, road engineering, as a key component, is expanding in both scale and quantity. Road mechanical engineering surveying, as a core link in ensuring the quality and progress of road construction, places extremely stringent demands on accurate and efficient surveying operations.

[0003] In the prior art, a measuring device for road machinery engineering disclosed in application number 202221731196.8 includes a measuring instrument. The lower end of the measuring instrument is provided with a telescopic rod for connection. The lower end of the telescopic rod is provided with uniformly distributed rectangular grooves. The telescopic rod is connected to a limiting block through the rectangular grooves. The limiting block is limited and set in a connecting seat. Through the setting of a second support rod, the upper end of the second support rod is rotatably connected to a first support frame through a rotating shaft. The other end of the second support rod is screwed into a first threaded rod through a thread. The first support frame is hollowed out to facilitate the rotation and storage of the second support rod. Similarly, the second support rod is screwed into the first threaded rod through a thread to adjust the support height and then adjust the level according to the ground. At the same time, the lower end of the first threaded rod is in contact with the ground through an arc-shaped block. The elasticity and anti-slip properties of the elastic sheet and rubber pad increase the stability of the arc-shaped block in contact with the ground.

[0004] One of the aforementioned measuring devices for road machinery engineering has a telescopic rod at its bottom for easy height adjustment via a support rod. However, the support frame of this device only provides basic support and lacks a vibration damping and protection structure for the measuring device. In actual road construction scenarios, the strong vibrations generated by the operation of mechanical equipment at the road construction site are particularly prominent. This vibration is directly transmitted to the measuring instrument through the support structure. Due to the lack of vibration damping, precision components such as sensors inside the measuring instrument are prone to displacement or even damage due to continuous vibration, leading to problems such as fluctuations and errors in measurement data. This not only affects the reliability of the measurement results but can also interfere with construction decisions, delay project progress, and even create hidden dangers for road construction quality. Therefore, we propose a measuring device for road machinery engineering that does not meet current needs. Utility Model Content

[0005] The purpose of this utility model is to provide a measuring device for road machinery engineering, in order to solve the problem mentioned in the background art that the strong vibration of mechanical operation in current road construction is directly transmitted to the measuring instrument through the support structure. The support frame has no shock absorption structure, and the internal sensor components are easily displaced and damaged by vibration, resulting in fluctuations and errors in the measurement data.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A measuring device for road machinery engineering includes a fixed triangular support frame, a support rod that slides inside the triangular support frame, a fixed base plate at the top of the support rod, and a ground fixing component at the bottom of the triangular support frame. The fixed base plate is provided with a vibration damping mechanism for reducing the vibration of the measuring instrument.

[0008] Preferably, the vibration damping mechanism includes a vertical plate installed on one outer wall of the fixed base plate. The vertical plate is provided with a sliding guide, a first damping component, and a second damping component. The sliding guide includes a guide block, a sliding rail, a sliding block, and a connecting plate. The guide block is installed on the inner wall of the vertical plate. Guide grooves are symmetrically opened on the outer walls of both sides of the guide block. The sliding rail is vertically installed inside each guide groove. The sliding block slides on each sliding rail. The two sliding blocks located in front of the guide block are connected by a connecting plate. A supporting base plate is fixedly connected to the outer wall of the connecting plate.

[0009] Preferably, the first shock absorber includes a rectangular shock absorber spring and a mounting base plate. The rectangular shock absorber spring is mounted on the top of the mounting base plate and the bottom of the supporting base plate. The bottom of the rectangular shock absorber spring is connected to the top of the mounting base plate through a spring seat, and the top of the rectangular shock absorber spring is connected to the bottom of the supporting base plate through a spring seat.

[0010] Preferably, the second shock absorber includes an air spring isolator and a mounting base. The mounting base includes a base and a top plate that is slidably inserted into the base. The air spring isolator is installed on the top of the supporting base plate, and the top of the air spring isolator is connected to the bottom of the base.

[0011] Preferably, the top of the top plate is fixedly connected to the bottom of the measuring instrument.

[0012] Preferably, the ground fixing component includes a base plate and a tapered insert rod located vertically at the bottom of the base plate, and the bottom of the triangular support frame is connected to the top of the base plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. This application forms a dual damping structure by combining the first damping component (rectangular damping spring) and the second damping component (air spring vibration isolator). The rectangular damping spring can absorb medium and high frequency vibrations, and the air spring vibration isolator can buffer low frequency vibrations, effectively blocking the transmission of construction machinery vibrations to the measuring instrument through the support structure, and avoiding sensor displacement or damage due to vibration.

[0015] 2. Ensure the reliability of measurement data, reduce the interference of vibration on the measuring instrument, reduce data fluctuations and the probability of errors, provide accurate data support for construction decisions, and indirectly avoid project delays and quality risks caused by data deviations.

[0016] 3. The structure is highly stable and adaptable. The sliding guide ensures the stable sliding of the measuring instrument during the vibration reduction process and avoids lateral deviation. The air spring vibration isolator can be adapted to measuring instruments of different weights through air pressure adjustment, while the rectangular damping spring is adapted to normal load changes and various measurement scenarios.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figure 1 , Figure 2and Figure 6 As shown, a measuring device for road machinery engineering includes a fixed triangular support frame 1, a support rod 2 slidably located inside the triangular support frame 1, a fixed base plate 3 located at the top of the support rod 2, and a ground fixing component 4 located at the bottom of the triangular support frame 1. The support rod 2 is slidably located inside the triangular support frame 1. A bolt for position adjustment is provided on the outer wall of the triangular support frame 1. The end of the bolt penetrates the triangular support frame 1 and abuts against the outer wall of the support rod 2. By tightening the bolt, the friction between the bolt and the outer wall of the support rod 2 is utilized to achieve position adjustment. The position of the support pole 2 is fixed; loosening the bolts allows the support pole 2 to slide up and down along the inner wall of the triangular support frame. After adjusting the height, the bolts are tightened again to complete the positioning. The ground fixing component 4 includes a base plate 41 and a tapered insert 42 vertically located at the bottom of the base plate 41. The top of the tapered insert 42 is fixedly connected to the base plate 41, and the bottom of the triangular support frame 1 is fixedly connected to the top of the base plate 41. The base plate 41 of the ground fixing component increases the contact area with the ground, making the support of the measuring device on the ground more stable and less prone to shaking or tilting. At the same time, the tapered insert 42 at the bottom of the base plate 41 can be inserted into the ground, further enhancing the connection strength between the measuring device and the ground, especially on soft ground, effectively preventing the device from shifting.

[0026] The tapered stake 42 can adapt to various terrain conditions, such as grassland and muddy ground. By inserting the stake into the ground, the measuring device can remain stable even on uneven ground, improving its applicability. When it is necessary to move the measuring device, the ground fixing part can be easily pulled out of the ground, and then the entire device can be moved to the new measuring location before the ground fixing part is reinstalled, making the operation quite convenient.

[0027] Please refer to the attached diagram. Figure 2 - Figure 6As shown, a vibration damping mechanism 5 for damping the measuring instrument is provided on the fixed base plate 3. The bottom of the fixed base plate 3 is fixedly connected to the top of the support rod 2. The vibration damping mechanism 5 includes a vertical plate 51 installed on one side of the outer wall of the fixed base plate 3. The vibration damping mechanism 5 is installed on the one side of the outer wall of the fixed base plate 3 through the vertical plate 51. The vertical plate 51 serves as the basic support component of the entire vibration damping mechanism. A sliding guide 52, a first damping component 53, and a second damping component 54 are provided on the vertical plate 51. The sliding guide 52 includes a guide block 521, a sliding guide rail 522, a sliding block 523, and a connecting plate 524. 521 is installed on the inner wall of the vertical plate 51 to provide a fixed foundation for the sliding structure. The sliding guide rail 522 is vertically fixed in the guide grooves 526 on both sides of the guide block 521. The sliding block 523 is sleeved on the sliding guide rail 522 and can slide up and down along the guide rail. The two sliding blocks 523 located in front of the guide block 521 are connected by a connecting plate 524. A supporting base plate 525 is fixedly connected to the outer wall of the connecting plate 524. The two sliding blocks 523 are connected as a whole by the connecting plate 524. The supporting base plate 525 is fixed to the outer wall of the connecting plate 524 to form a load-bearing structure that can move synchronously with the sliding blocks.

[0028] The first damping component 53 includes a rectangular damping spring 531 and a mounting base plate 532, the end of which is connected to the outer wall of the guide block 521.

[0029] A rectangular damping spring 531 is installed on the top of the mounting base plate 532 and the bottom of the supporting base plate 525. The bottom of the rectangular damping spring 531 is connected to the top of the mounting base plate 532 through a spring seat 533, and the top of the rectangular damping spring 531 is connected to the bottom of the supporting base plate 525 through a spring seat 533. The sliding block 523 slides vertically along the sliding guide rail 522, restricting the movement of the supporting base plate 525 to only up and down, avoiding lateral offset or swaying during vibration, ensuring that the force of the damping component is transmitted in the preset direction, and improving the damping efficiency. The rigid connection between the guide block 521 and the guide rail provides a stable sliding frame for the entire damping mechanism, preventing component deformation or misalignment due to vibration. The rectangular damping spring 531 absorbs low-frequency, large-amplitude vibrations such as ground bumps and impacts during equipment placement through elastic deformation, reducing the transmission of vibration to the supporting base plate 525. The rigidity of the spring itself can help support the weight of the measuring instrument, and the connection method of the spring seat 533 avoids direct rigid contact between the spring and the component, reducing wear.

[0030] The second damping component 54 includes an air spring isolator 541 and a mounting base. The mounting base includes a base 543 and a top plate 542 slidably inserted into the base 543. The air spring isolator 541 is mounted on the top of the supporting base plate 525, with the top of the air spring isolator 541 connected to the bottom of the base 543. The top of the top plate 542 is fixedly connected to the bottom of the measuring instrument. The air spring isolator 541, through internal air pressure regulation, can absorb high-frequency, small-amplitude vibrations (such as ambient breezes and minor ground tremors), further buffering residual vibrations not filtered by the first damping component, achieving "dual damping." The top plate 542 of the mounting base is slidably inserted into the base 543, and with the flexible support of the air spring, it can adapt to slight vibrations in different directions, such as small horizontal or tilted swaying, expanding the damping range. The top plate 542, directly connected to the measuring instrument, transmits force through a flexible structure, preventing vibration from directly acting on precision components inside the measuring instrument, such as sensors and lenses, reducing measurement errors and equipment wear.

[0031] Workflow: First, place the ground fixing component 4 on the ground at the measurement point. Insert the tapered rod 42 at the bottom of the base plate 41 into the ground using external force, so that the base plate 41 is stably attached to the ground, completing the installation of the ground fixing component. Since the bottom of the triangular support frame 1 is fixedly connected to the top of the base plate 41, the triangular support frame 1 is stably supported on the ground after the ground fixing component is installed. Loosen the bolts on the outer wall of the triangular support frame 1 used for position adjustment. At this time, the support rod 2 can slide freely up and down along the inner wall of the triangular support frame. Push the support rod 2 according to the measurement requirements, adjust it to a suitable height, tighten the bolts, and use the friction between the bolts and the outer wall of the support rod 2 to fix the position of the support rod 2, completing the height adjustment. Install the measuring instrument on the top plate 542 of the second shock absorber 54 mounting base, so that the measuring instrument is fixedly connected to the top plate 542. Then slide the top plate 542 into the base 543.

[0032] When the measuring device is subjected to external vibration, the vibration is first transmitted to the triangular support frame 1 and the support rod 2, and then transmitted to the fixed base plate 3 and the vibration damping mechanism 5 on it. In the sliding guide 52, the sliding block 523 will slide vertically along the sliding guide rail 522, restricting the support base plate 525 to only move in the up and down direction, avoiding lateral displacement. The rectangular damping spring 531 of the first damping component 53 absorbs low-frequency, large-amplitude vibration through elastic deformation, and performs preliminary buffering of the vibration. The residual vibration after being buffered by the first damping component is transmitted to the second damping component 54 at the top of the support base plate 525. The air spring vibration isolator 541 absorbs high-frequency, small-amplitude vibration through internal air pressure regulation. At the same time, the top plate 542 of the mounting base is slidably inserted with the base 543, and with the flexible support of the air spring, it adapts to slight vibrations in different directions and further filters the vibration. Ultimately, the vibration transmitted to the measuring instrument is greatly reduced. After the measurement is completed, the measuring instrument is removed from the top plate 542, the support pole 2 is lowered to a suitable position and the bolts are tightened to reduce the overall height of the device. Then, the conical plug 42 of the ground fixing part 4 is pulled out from the ground, and the entire device is moved to a new measurement location. The above installation and adjustment process is repeated.

[0033] The sliding guide 52 of this application restricts the movement direction of the support base plate 525, ensuring that the force of the shock absorber is transmitted along the preset direction, avoiding lateral deviation or swaying during vibration, providing a stable working foundation for the vibration damping mechanism, and improving the overall vibration damping efficiency.

[0034] Furthermore, the rectangular damping spring 531 of the first damping component 53 and the air spring isolator 541 of the second damping component 54 form a dual damping structure. The rectangular damping spring can effectively absorb low-frequency, large-amplitude vibrations, while the air spring isolator can filter high-frequency, small-amplitude vibrations. The two work together to buffer different types of vibrations in layers, significantly reducing the amount of vibration transmitted to the measuring instrument.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
