Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and specifically to a slope adjustment device for pre-embedded steel plates of bridges with multi-directional slope adjustment function. Background Technique

[0002] With the rapid advancement of China's transportation industry and the grid development of high-grade roads, various interchange and overpass bridge projects have emerged. Most of these bridge structures have characteristics such as bends and slopes. T-beams have large load-bearing capacity, large anti-torsion stiffness, strong linear adaptability, and strong adaptability to construction methods. They are widely used in the construction of overpass bridges, interchange bridges, and interchange ramp bridges that cross various obstacles. The steel plate at the bottom of the beam in the prefabrication production of T-beams is the top steel plate of the bearing, which is a steel plate pre-embedded in advance during the production process of T-beams and serves the bearing. Its function is to increase the anti-impact performance of the beam body and increase the contact area of the force points between the beam body and the bearing. Usually, by installing a slope adjustment device to adjust the slope of the pre-embedded steel plate, it is ensured that the slope is consistent with the longitudinal slope and transverse slope of the bridge design to ensure that the bearing is in a horizontal state after the beam slab is installed. If the longitudinal slope and position of the pre-embedded steel plate are inaccurate, the bearing will be eccentrically loaded after the beam body is installed, which will cause the bearing to be damaged prematurely and seriously affect the service life of the bridge. The existing slope adjustment devices for precast steel plates of bridges have the following problems when in use:

[0003] There are errors in the welding or pasting of the pre-embedded steel plate in actual operation, making it difficult to tightly fit the steel plate with the horizontal plane of the bearing, so that it is difficult to control the transverse slope and longitudinal slope of the beam bottom within the allowable range of the specification. At present, there are also many slope adjustment devices for bridge pre-embedded steel plates, such as a beam bottom pre-embedded steel plate automatic slope adjuster and its usage method used in bridge prefabrication production with the publication number of CN115847600A; a positioning and adjustment method for beam bottom pre-embedded steel plates with the publication number of CN113001752B; and a slope adjustment device for a bearing pre-embedded steel plate with the publication number of CN216765568U.

[0004] Based on the above-mentioned publicly disclosed patents, but in the actual use process, most of the pre-embedded steel plate bearings in the bridge prefabrication process have a single-directional slope adjustment function. There are problems that the slope adjustment accuracy of the existing two-way slope adjustment bearings is difficult to control, and the slope adjustments of the transverse slope and longitudinal slope affect each other. Therefore, improvements are needed. Summary of the Invention

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 8, the present invention provides a slope-adjusting device for pre-embedded steel plates of a bridge with multi-directional slope-adjusting function, which includes a support bottom plate 1, a support top plate 2, a two-way slope-adjusting component and a driving component. The two-way slope-adjusting component and the driving component are both arranged between the support bottom plate 1 and the support top plate 2. The two-way slope-adjusting component uses a spherical hinge support 301, a hemispherical hinge 302 and a top support 303 as the main body of two-way slope adjustment to achieve longitudinal slope adjustment and transverse slope adjustment simultaneously; the driving component uses a first driven gear 501, a second driven gear 502, a first driving gear 504 and a second driving gear 506 to drive the two-way slope-adjusting component to rotate between the support bottom plate 1 and the support top plate 2 by gear transmission to freely adjust the support direction.

[0036] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , the two-way slope-adjusting component includes a first fitting hinge groove 304, a second fitting hinge groove 305, a strip-shaped convex structure 306, an inner concave chute 307, a hydraulic fixed base 308, a transverse slope-adjusting hydraulic device 309 and a longitudinal slope-adjusting hydraulic device 310. The first fitting hinge groove 304 is opened at the bottom of the top support 303, the second fitting hinge groove 305 is opened at the bottom of the hemispherical hinge 302, the strip-shaped convex structure 306 is fixedly connected to the outer wall of the hemispherical hinge 302, the inner concave chute 307 is opened inside the first fitting hinge groove 304, the hydraulic fixed base 308 is rotatably connected to the top of the support bottom plate 1, the transverse slope-adjusting hydraulic device 309 and the longitudinal slope-adjusting hydraulic device 310 are fixedly installed on the top of the hydraulic fixed base 308. The strip-shaped convex structure 306 and the inner concave chute 307 are matched in shape. The top of the transverse slope-adjusting hydraulic device 309 is movably installed at the bottom of the hemispherical hinge 302, the top of the longitudinal slope-adjusting hydraulic device 310 is movably installed at the bottom of the top support 303. The spherical hinge support 301 is fixedly connected to the top of the support bottom plate 1, the top support 303 is rotatably connected to the bottom of the support top plate 2. The top support 303 is anchored to the outer wall of the hemispherical hinge 302 through the opening of the first fitting hinge groove 304, and the hemispherical hinge 302 is anchored to the outer wall of the spherical hinge support 301 through the opening of the second fitting hinge groove 305.

[0037] It should be noted that the two-way slope adjustment component takes the spherical hinge support 301, the hemispherical hinge 302 and the top support 303 as the main body of the two-way slope adjustment component. By setting the transverse slope adjustment hydraulic device 309 and the longitudinal slope adjustment hydraulic device 310, by regulating the hydraulic pressure of the transverse slope adjustment hydraulic device 309, the hydraulic rod is driven, the hemispherical hinge 302 is driven, and the top support 303 is driven through the strip-shaped convex structure 306 connected thereto, and the support top plate 2 is driven to complete the transverse slope adjustment of the embedded steel plate at the bottom of the beam. Then, by regulating the hydraulic pressure of the longitudinal slope adjustment hydraulic device 310, the hydraulic rod is driven, the top support 303 is driven, and through the corresponding arrangement of the concave chute 307 inside the first fitting hinge groove 304 of the top support 303, a longitudinal relative sliding can be generated with the hemispherical hinge 302, thereby driving the support top plate 2 to complete the longitudinal slope adjustment of the embedded steel plate at the bottom of the beam. By using the transverse slope adjustment hydraulic device 309 and the longitudinal slope adjustment hydraulic device 310 in cooperation, precise regulation of any angle of the cross slope and longitudinal slope can be achieved during the erection of the beam body. Generally, the longitudinal slope of a two-way slope adjustment bridge is relatively large and the cross slope is relatively small, so the requirement for the slope adjustment range is higher. The longitudinal slope adjustment hydraulic device 310 is located outside the transverse slope adjustment hydraulic device 309, with a larger lever arm, making full and effective use of the hydraulic pressure of the hydraulic device. The tops of the hydraulic rods of the transverse slope adjustment hydraulic device 309 and the longitudinal slope adjustment hydraulic device 310 are spherical. The strip-shaped convex structure 306, the spherical hydraulic pressure and the hemispherical hinge 302, etc. make the transverse slope adjustment and the longitudinal slope adjustment not affect each other, and it is easier to precisely control the two-way slope.

[0038] In some embodiments, refer to Figure 1 、 Figure 7, the drive assembly includes a first fixing bracket 503, a second fixing bracket 505, a first transmission universal joint 507, a second transmission universal joint 508, and a reduction gearbox 511.

The first driving gear 504 is rotatably connected to the inner side of one end of the first fixing bracket 503, the second driving gear 506 is rotatably connected to the inner side of one end of the second fixing bracket 505. The first driving gear 504 meshes with the second driven gear 502, the second driving gear 506 meshes with the first driven gear 501. The shape of the transmission connection square rod 510 matches the inner shape of the transmission connection square sleeve 509, and the transmission connection square rod 510 is slidably connected to the inner side of the transmission connection square sleeve 509. The output gear of the reduction gearbox 511 meshes with the first driving gear 504.

[0039] It should be noted that the reduction gearbox 511 is provided with a worm and a worm wheel inside, and there is also a gear that can mesh with the first driving gear 504 and is coaxial with the internal worm wheel. By inserting an external device, such as a hexagonal wrench, into the hexagonal inner sleeve 512 and rotating it, the first driving gear 504 can be driven to rotate. The first driving gear 504 then drives the second driving gear 506 to rotate through the cooperation of the first transmission universal joint 507, the second transmission universal joint 508, the transmission connection square sleeve 509, and the transmission connection square rod 510. The first driving gear 504 and the second driving gear 506 rotate and mesh with the second driven gear 502 and the first driven gear 501 respectively, thereby driving the two-way slope adjustment assembly to rotate, facilitating the free adjustment of the support direction and improving the use flexibility.

[0040] A lubrication assembly and a damping assembly are arranged between the two-way slope adjustment assemblies. The lubrication assembly lubricates the main components of the two-way slope adjustment assembly by opening a first lubricating oil groove 404 and a second lubricating oil groove 405. The damping assembly increases the damping during slope adjustment by arranging a plurality of damping rods 604, and the damping rods 604 surround the two-way slope adjustment assembly for one week.

[0041] In some embodiments, refer to Figure 2 、 Figure 3 、 Figure 4 、Figure 5 The lubricating assembly includes a lubricating oil storage cavity 401, an oil injection pipeline 402, a first communication oil injection hole 403 and a second communication oil injection hole 406. The lubricating oil storage cavity 401 is opened inside the top support 303. The oil injection pipeline 402 is fixedly connected to the side wall of the top support 303. The first communication oil injection hole 403 is opened inside the top support 303. The second communication oil injection hole 406 is opened inside the hemispherical hinge 302. The first lubricating oil groove 404 is opened inside the first fitting hinge groove 304. The second lubricating oil groove 405 is opened on the outer wall of the hemispherical hinge 302. One end of the oil injection pipeline 402 is communicated with the inside of the lubricating oil storage cavity 401.

The second communication oil injection hole 406 is respectively communicated with the second lubricating oil groove 405 and the second fitting hinge groove 305.

[0042] It should be noted that by providing the lubricating oil storage cavity 401 for storing lubricating oil, the lubricating oil can be added into the lubricating oil storage cavity 401 through the provided oil injection pipeline 402. The lubricating oil can flow between the first lubricating oil groove 404 and the second lubricating oil groove 405 through the first communication oil injection hole 403 to lubricate between the top support 303 and the hemispherical hinge 302. Then the lubricating oil flows to the connection position between the hemispherical hinge 302 and the spherical hinge support 301 through the second communication oil injection hole 406, so as to lubricate between the hemispherical hinge 302 and the spherical hinge support 301, reduce the wear between various components, and further adjust the accuracy of the equipment.

[0043] The damping assembly is arranged between the two-way slope adjustment assemblies. The damping assembly is provided with a plurality of damping rods 604. The damping rods 604 surround the two-way slope adjustment assembly for one week. During the slope adjustment process, the damping rods 604 are used to increase the damping during slope adjustment, enhancing the stability and support effect during slope adjustment.

[0044] In some embodiments, referring to Figure 1 、 Figure 8 The damping assembly includes a first inner ball groove 601, a support seat 602, a second inner ball groove 603, a first ball head 605 and a second ball head 606. The first inner ball groove 601 is opened at the top of the second driven part 502. The support seat 602 is fixedly connected to the bottom outer wall of the top support 303. The second inner ball groove 603 is opened at the bottom of the support seat 602. The first ball head 605 and the second ball head 606 are respectively fixedly connected to both ends of the damping rod 604. Both ends of the damping rod 604 are movably installed inside the first inner ball groove 601 and the second inner ball groove 603 respectively through the settings of the first ball head 605 and the second ball head 606, and a plurality of damping rods 604 are arranged in a circular array outside the top support 303 and the hydraulic fixed base 308.

[0045] It should be noted that the two ends of several damping rods 604 are installed with a first ball head 605 and a second ball head 606. The first ball head 605 and the second ball head 606 are installed in the first inner ball groove 601 and the second inner ball groove 603. When adjusting the lateral angle and the longitudinal angle, the two ends of the damping rod 604 can freely change the angle and expand and contract, which will not affect the adjustment of the angle. And the damping rod 604 is set to increase the damping during slope adjustment by using the damping rod 604, enhancing the stability and support effect during slope adjustment.

[0046] The working process and principle of the present invention: When in use, by regulating the hydraulic pressure of the lateral slope adjustment hydraulic device 309, the hydraulic rod is driven, and the hemispherical hinge 302 is driven. Through the strip-shaped convex structure 306 connected thereto, the top support 303 is driven, and the support top plate 2 is driven to complete the lateral slope adjustment of the embedded steel plate at the bottom of the beam. Then, by regulating the hydraulic pressure of the longitudinal slope adjustment hydraulic device 310, the hydraulic rod is driven, and the top support 303 is driven. And through the corresponding arrangement of the concave sliding groove 307 inside the first fitting hinge groove 304 of the top support 303, a longitudinal relative sliding can be generated with the hemispherical hinge 302, thereby driving the support top plate 2 to complete the longitudinal slope adjustment of the embedded steel plate at the bottom of the beam. By using the lateral slope adjustment hydraulic device 309 and the longitudinal slope adjustment hydraulic device 310 in cooperation, precise regulation of any angle of the cross slope and the longitudinal slope can be achieved during the erection of the beam body. During the slope adjustment process, lubricating oil can be added to the lubricating oil storage cavity 401 through the set oil injection pipeline 402. The lubricating oil can flow between the first lubricating oil groove 404 and the second lubricating oil groove 405 through the first communication oil injection hole 403 to lubricate between the top support 303 and the hemispherical hinge 302. Then the lubricating oil flows to the connection position between the hemispherical hinge 302 and the ball hinge support 301 through the second communication oil injection hole 406, so as to be able to lubricate between the hemispherical hinge 302 and the ball hinge support 301, which can reduce the wear between each component, further adjust the precision of the equipment, and by an external device, inserting and rotating the hexagonal inner sleeve 512 can drive the first driving gear 504 to rotate. The first driving gear 504 drives the second driving gear 506 to rotate through the cooperation of the first transmission universal joint 507, the second transmission universal joint 508, the transmission connection square sleeve 509 and the transmission connection square rod 510. The first driving gear 504 and the second driving gear 506 rotate and are respectively engaged with the second driven gear 502 and the first driven gear 501, thereby driving the two-way slope adjustment assembly to rotate, facilitating the free adjustment of the support direction, improving the use flexibility, and during the adjustment process, since the damping rod 604 surrounds the outside of the two-way slope adjustment assembly, the damping rod 604 is used to increase the damping during slope adjustment, enhancing the stability and support effect during slope adjustment.
