Technical Field

[0001] This invention relates to bridge beam monitoring technology, specifically to a bridge beam monitoring device based on laser scanning. Background Technology

[0002] As a key component of transportation infrastructure, the stability of bridge beam structures directly affects traffic safety and transportation efficiency. Laser scanning technology, with its advantages of high precision, non-contact operation, and rapid data acquisition, has been widely used in the field of bridge beam monitoring. It can effectively acquire three-dimensional information of the beam surface and realize quantitative analysis of key parameters such as crack width and structural deformation. However, existing bridge beam monitoring devices based on laser scanning still have many shortcomings in practical applications, which restrict the monitoring effect and practicality.

[0003] Existing bridge beam laser scanning monitoring devices have significant shortcomings in terms of support stability, installation adaptability, height adjustment accuracy, and portable deployment, failing to fully meet the actual needs of high-precision, long-term stable monitoring of bridge beams. Therefore, this invention provides a laser scanning-based bridge beam monitoring device that offers robust support, convenient installation, precise adjustment, and strong adaptability to address the deficiencies of existing technologies and improve the reliability and efficiency of bridge beam monitoring. Summary of the Invention

[0004] The purpose of this invention is to provide a bridge beam monitoring device based on laser scanning to solve the problems of bridge beam monitoring in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bridge beam monitoring device based on laser scanning, comprising an adjustment component, a blocking disc, a spiral rod, a support component, a laser scanner body, and an installation component; the adjustment component has a blocking disc integrally formed at its bottom, a spiral rod integrally formed at its bottom, and a support component disposed outside the spiral rod, which can stably support the adjustment component by unfolding the support component; the adjustment component has an installation component disposed at its top, which is movably connected to the base of the laser scanner body to achieve stable installation, and the bridge beam is stably monitored by the laser scanner body.

[0006] Furthermore, the mounting components include a support plate, a ring, and a compression angle; the support plate is movably adapted to the base of the laser scanner body to achieve stable support for the laser scanner body.

[0007] Furthermore, a guide opening is provided on the side of the lifting plate, and a spiral lever is movably disposed in the guide opening. The end of the spiral lever is fixedly connected to the side of the ring. The ring is rotatably assembled in the lifting plate, and the ring can be driven to rotate synchronously by moving the spiral lever.

[0008] Furthermore, a spiral pressing disc is screwed onto the outside of the spiral lever, and the rotation state of the ring can be locked by turning the spiral pressing disc.

[0009] Furthermore, the top of the ring is rotatably connected to the extrusion angle via a shaft, and the top of the extrusion angle has an arc-shaped guide opening. A limit guide rod is disposed inside the arc-shaped guide opening, and the top end of the limit guide rod is fixedly connected to the inner top surface of the support plate. When the ring rotates, it can drive the extrusion angle to extrude and limit the base of the laser scanner body, thereby improving the stability of the installation.

[0010] Furthermore, the adjustment assembly includes an outer tube, a first threaded sleeve, a threaded rod, and a circular column; the circular column is movably disposed inside the outer tube, and the top of the circular column is integrally formed with a threaded rod, the top end of which is fixedly connected to the bottom surface of the support plate, and the height of the laser scanner body can be adjusted by the lifting and lowering of the threaded rod inside the outer tube.

[0011] Furthermore, the threaded rod is screwed to the first threaded sleeve, which is rotatably mounted in the upper port of the outer tube. By screwing the first threaded sleeve, the threaded rod can be driven to extend or retract, thereby achieving precise adjustment of the height of the laser scanner body.

[0012] Furthermore, a guide groove is provided on the inner wall of the outer tube, and a spherical groove is provided on the outside of the circular column. A retaining ball is movably arranged between the spherical groove and the guide groove. The threaded rod is circumferentially limited by the cooperation between the guide groove and the retaining ball to prevent rotational deviation during the adjustment process.

[0013] Furthermore, the support assembly includes an upper cross collar, a lower cross collar, support legs, and auxiliary support rods; the spiral rod has a cross guide groove on its outside, which movably passes through the upper and lower cross collars; the upper cross collar has three sets of hinge blocks arranged in a ring array on its outside, each set of hinge blocks being rotatably connected to the support leg via a pivot pin, and unfolding the support leg can stably support the adjustment assembly; a second threaded sleeve is rotatably configured inside the upper cross collar, and the second threaded sleeve is screwed to the spiral rod; by screwing the second threaded sleeve, the upper and lower cross collars can be driven to move along the spiral rod, realizing convenient unfolding and retraction of the support leg.

[0014] Furthermore, each of the three sets of support legs has a storage groove on its inner wall. The storage groove is rotatably connected to the auxiliary support rod through a rotating rod. The bottom of the auxiliary support rod is fixedly connected to the lower cross collar. When the support leg is unfolded, the auxiliary support rod can limit and stabilize it. When the support leg is folded, the auxiliary support rod is stored in the storage groove.

[0015] Compared with existing technologies, by coordinating the adjustment components, support components, and installation components, the laser scanner body can be stably deployed and the bridge beam can be stably monitored. Tightening the second threaded sleeve of the support component drives the cross collar to move and unfold the support leg. The auxiliary support rod rotates out of the limit position at the same time, placing the laser scanner body base on the support plate of the installation component. Turning the spiral lever drives the ring to rotate, causing the extrusion angle to extrude the positioning base under the action of the guide limit. Tightening the spiral extrusion plate locks it. The adjustment component limits the threaded rod circumferentially through the cooperation of the guide groove and the ball, ensuring accurate height adjustment and making the scanner adaptable to different monitoring heights.

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This invention relates to a bridge beam monitoring device based on laser scanning. However, the laser scanning monitoring device for bridge beams has significant shortcomings in terms of support stability, installation adaptability, height adjustment accuracy, and portable deployment, and cannot fully meet the actual needs of high-precision and long-term stable monitoring of bridge beams.

[0027] like Figure 1-8 As shown, this solution discloses a bridge beam monitoring device based on laser scanning, including an adjustment component 1, a blocking plate 2, a spiral rod 3, a support component 4, a laser scanner body 5, and an installation component 6. The bottom of the adjustment component 1 is provided with an integrally formed blocking plate 2, and the bottom of the blocking plate 2 is provided with an integrally formed spiral rod 3. The outside of the spiral rod 3 is provided with the support component 4. By unfolding the support component 4, the adjustment component 1 can be stabilized. The top of the adjustment component 1 is provided with the installation component 6. The interior of the installation component 6 is movably connected to the base of the laser scanner body 5, thereby achieving stable installation of the laser scanner body 5. The bridge beam is monitored through the laser scanner body 5.

[0028] To ensure stable scanning of the code by the laser scanner body 5 when monitoring the bridge beam, such as Figure 7-8As shown; the mounting assembly 6 includes a support plate 601, a ring 602, and a compression angle 603. The support plate 601 is internally connected to the base of the laser scanner body 5, so that the laser scanner body 5 is mounted on top of the support plate 601 (the laser scanner body 5 is known in this application and will not be explained in detail). A guide opening 607 is provided on the side of the support plate 601, and a spiral lever 609 is movably disposed inside the guide opening 607. The end of the spiral lever 609 is fixed to the side of the ring 602. The ring 602 is rotatably disposed inside the support plate 601. When the spiral lever 609 is turned, the ring 602 rotates inside the support plate 601. The spiral lever 609 is externally screwed to the spiral lever 609. When the knob screws the disc 608, the ring 602 is locked inside the support disc 601. The top of the ring 602 is rotatably connected to the inside of the extrusion angle 603 via the shaft 604 (the extrusion angle 603 is set in three groups, and the three groups of extrusion angles 603 are arranged in a ring array about the center of the ring 602). The top of the extrusion angle 603 is provided with an arc-shaped guide 605. The inside of the arc-shaped guide 605 is provided with a limit guide rod 606. The top of the limit guide rod 606 is fixed to the inner top surface of the support disc 601. The ring 602 rotates inside the support disc 601, causing the extrusion angle 603 to press against the base of the laser scanner body 5, thereby the laser scanner body 5 is stably installed on the top surface of the mounting assembly 6.

[0029] In order to achieve height adjustment of the laser scanner body 5, such as Figure 3-8 As shown; the adjustment assembly 1 includes an outer tube 101, a first threaded sleeve 102, a threaded rod 103, and a circular column 104. The circular column 104 is movably disposed inside the outer tube 101. The threaded rod 103 is integrally formed on the top of the circular column 104. The top end of the threaded rod 103 is fixed to the bottom surface of the support plate 601, thereby enabling adjustment of the threaded rod 103 within the outer tube 101, achieving vertical adjustment of the laser scanner body 5's position. The first threaded sleeve 102 is screwed onto the outside of the threaded rod 103. Inside, the outer side of the first threaded sleeve 102 is rotatably mounted inside the upper port of the outer tube 101. When the first threaded sleeve 102 is turned, the threaded rod 103 can extend and retract inside the outer tube 101. The inner wall of the outer tube 101 is provided with a guide groove 107, and the outer side of the circular column 104 is provided with a spherical groove 105. A retaining ball 106 is movably arranged between the spherical groove 105 and the guide groove 107. When the threaded rod 103 extends and retracts inside the outer tube 101, the guide groove 107 provides a limiting effect on the threaded rod 103.

[0030] To ensure the laser scanner body 5 is stably supported on top of the adjustment assembly 1, such as... Figure 4-6As shown; the support assembly 4 includes an upper cross collar 401, a lower cross collar 402, a support leg 403, and an auxiliary support rod 404. The spiral rod 3 has a cross guide groove 7 inside, which movably connects the interiors of the upper cross collar 401 and the lower cross collar 402. The upper cross collar 401 has three sets of hinge blocks arranged in a ring array on its outer surface. Each set of hinge blocks is rotatably connected to the support leg 403 via a pivot pin, thus enabling support of the adjustment assembly 1 by unfolding the support leg 403. The inner walls of the three sets of support legs 403 each have a storage groove 405, which is rotatably connected to the auxiliary support rod 404 via a rotating rod. Above, the bottom hinge block of the auxiliary support rod 404 is fixed to the outside of the lower cross collar 402. When the support leg 403 is unfolded, the auxiliary support rod 404 plays a limiting and stabilizing role. When the support leg 403 is folded, the auxiliary support rod 404 is stored in the storage groove 405. The upper cross collar 401 has a second threaded sleeve 406 rotatably installed inside. The inside of the second threaded sleeve 406 is screwed to the outside of the spiral rod 3. Turning the second threaded sleeve 406 causes the upper cross collar 401 and the lower cross collar 402 to move up and down outside the spiral rod 3, so as to unfold the support leg 403 and thus achieve stable support for the laser scanner body 5.

[0031] Working principle: This device achieves stable deployment of the laser scanner body 5 and stable monitoring of the bridge beam through the coordinated operation of adjustment component 1, support component 4, and installation component 6. By screwing the second threaded sleeve 406 in the support component 4, and utilizing its screw connection with the screw rod 3, the upper cross collar 401 and the lower cross collar 402 are driven to move up and down relative to each other along the screw rod 3. This, in turn, drives the three sets of support legs 403 hinged to the upper cross collar 401 to unfold synchronously. During the unfolding of the support legs 403, the auxiliary support rod 404 rotates out from the storage groove 405. Through the fixed connection between the auxiliary support rod 404 and the lower cross collar 402, the support legs 403 are limited and supported. Finally, the support component 4 forms a stable support structure, providing a stable bearing foundation for the adjustment component 1 and subsequent components. First, the base of the laser scanner body 5 is placed inside the support plate 601 of the mounting assembly 6 to complete the initial bearing. Then, the spiral lever 609 in the guide port 607 of the support plate 601 is turned to drive the ring 602 fixed thereto to rotate within the support plate 601. The ring 602 drives the three sets of annular array compression angles 603 to move through the shaft 604. Under the guiding and limiting action of the arc-shaped guide port 605 and the limiting guide rod 606, the compression angles 603 gradually move towards the base of the laser scanner body 5 and form compression. Finally, the spiral compression plate 608 is turned to lock the position of the ring 602, so that the compression angles 603 are kept in a compression state, realizing the stable installation of the laser scanner body 5 and avoiding deviation during monitoring. The guide groove 107 and the ball 106 cooperate to form a circumferential limit on the threaded rod 103 to prevent rotational deviation during adjustment, ensuring the accuracy of height adjustment and making the laser scanner body 5 adaptable to the monitoring height of different bridge beams.

[0032] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
