Description

Technical Field

[0001] The utility model relates to the technical field of bridge hoisting, in particular to a hoisting device for a concrete bridge deck of a steel-concrete composite beam with rapid construction. Background Technique

[0002] Compared with a concrete beam, a steel-concrete composite beam has a reduced structural height, a reduced self-weight, saves formwork and scaffolding, and shortens the construction period; compared with a steel beam, the composite beam has a reduced structural height, an increased bearing capacity, an increased stiffness, a reduced steel consumption, and greatly improved durability. The concrete bridge deck structure of the steel-concrete composite beam, as an important part directly bearing vehicle loads and composite sections, is one of the most critical and complex stress structures of the steel-concrete composite beam. For the concrete bridge deck structure of the steel-concrete composite beam, the conventional construction methods are the in-situ casting method or the prefabrication in blocks. The in-situ casting method is to install concrete formwork on site and then pour concrete; the prefabrication in blocks means that the bridge deck is prefabricated in blocks in a factory and then transported to the site for installation, which can achieve rapid construction and cost savings.

[0003] After retrieval, the Chinese patent utility model patent with the publication number: CN212270680U discloses a concrete bridge deck of a steel-concrete composite beam with rapid construction. It is recorded in this patent that the concrete bridge deck includes an intermediate slab and cantilever slabs arranged on both transverse sides of the bridge, and the intermediate slab and the cantilever slabs are connected by corresponding connecting cross beams, which is a prefabricated integral structure; the longitudinal length of the connecting cross beam is 30%-35% of the longitudinal lengths of the intermediate slab and the cantilever slabs, and shear grooves are respectively formed between the longitudinal two sides of the connecting cross beam and the corresponding intermediate slab and cantilever slabs. Through a plurality of shear connectors arranged in the shear grooves, reliable connection between the concrete bridge deck and the top of the steel beam is realized. This utility model (publication number: CN212270680U) also discloses a hoisting system for a concrete bridge deck of a steel-concrete composite beam with rapid construction. This utility model (publication number: CN212270680U) not only meets the need for arranging a large number of shear connectors, but also avoids the technical problems of poor integrity of the bridge deck caused by transverse segmentation and large workload of formwork installation in in-situ construction.

[0004] However, the solution with the publication number: CN212270680U has the technical problem that the hoisting system lacks an adjustment and positioning component. When hoisting the bridge deck, precise position adjustment cannot be carried out, which will cause deviations in the splicing between the bridge decks, affecting the overall structural stability and aesthetics of the bridge. And inaccurate installation may cause the bridge deck to collide with surrounding structures during installation, resulting in component damage and even triggering safety accidents. To solve this technical problem, the utility model proposes a hoisting device for a concrete bridge deck of a steel-concrete composite beam with rapid construction. Content of the Utility Model

And the second sliding block 18 is slidably connected inside the second support guide rail 14 to limit and support the second sliding block 18. At the same time, the second limiting block 15 provided on the second support guide rail 14 limits the second sliding block 18.

[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that for the bottom plate 1, the crane body 3 and the mounting plate 2, the bottom end of the crane body 3 is fixedly connected to the middle of the mounting plate 2 through a plurality of first reinforcing plates 4. The first reinforcing plates 4 play the role of strengthening the connection. And the mounting plate 2 is fixedly installed in the middle of the bottom plate 1 through a plurality of bolts, and the bolts play the role of strengthening the connection. The bottom end of the second sliding block 18 is fixedly connected to a second connecting plate 19, which is a firm connection. A clamping assembly is provided at the bottom end of the second connecting plate 19. The clamping assembly includes a mounting member 20, a third hydraulic push rod 21 and a linkage plate 24. The mounting member 20 is fixedly installed at the bottom end of the second connecting plate 19, which is a firm connection. And the outside of the third hydraulic push rod 21 is fixedly installed inside the mounting member 20, which is a firm connection. At the same time, one side of the linkage plate 24 is fixedly installed at the output end of the third hydraulic push rod 21. The third hydraulic push rod 21 drives the linkage plate 24. The other side of the linkage plate 24 is fixedly connected to a second mounting bracket 25, which is a firm connection. And a second clamping plate 26 is fixedly installed outside the second mounting bracket 25, which is a firm connection. The other side of the third hydraulic push rod 21 is fixedly installed with a first mounting bracket 22, which is a firm connection. And a first clamping plate 23 is fixedly installed outside the first mounting bracket 22. The stable clamping of the bridge deck is realized through the mutual cooperation between the first clamping plate 23 and the second clamping plate 26.

[0027] Working principle: In actual use, first, the crane body 3 needs to be supported and stabilized by the mounting plate 2 at the bottom and multiple first reinforcing plates 4, and is installed on the bottom plate 1 through multiple bolts. When hoisting the bridge deck, the clamping assembly can be directly used. By starting the hydraulic push rod three 21, a linkage plate 24 and a second mounting bracket 25 are fixedly installed at the output end of the hydraulic push rod three 21, and a second clamping plate 26 is fixedly installed on the outer side of the second mounting bracket 25. By adjusting the second clamping plate 26 to cooperate with the first clamping plate 23, stable clamping of the bridge deck is achieved. At the same time, a first mounting bracket 22 is fixedly connected to the outer side of the first clamping plate 23, and is fixedly installed on the outside of the hydraulic push rod three 21 through the first mounting bracket 22, which can firmly grasp the bridge deck, effectively preventing it from shaking or slipping during hoisting. Moreover, the uniform and stable clamping force can avoid excessive local stress on the bridge deck, resulting in cracks or damage. After using the crane body 3 to hoist the bridge deck to the appropriate position, if adjustment is required, the hydraulic push rod one 10 can be directly started. The hydraulic push rod one 10 is fixedly installed on the outside of the crane body 3 through the fixing plate 11 and the fixed seat 12. The fixing plate 11 drives the connecting block 9 and the first sliding block 8, so that the first sliding block 8 slides inside the first support guide rail 6 and is limited by the first limiting block 7. Through the displacement of the first sliding block 8 and the connecting block 9, horizontal adjustment in the left and right directions is achieved. Moreover, the connecting block 9 and the second support guide rail 14 are stably connected by two second reinforcing plates 13. At this time, the hydraulic push rod two 17 is started. The hydraulic push rod two 17 is fixedly installed at one end of the second support guide rail 14 through the L-shaped plate 16. The output end of the hydraulic push rod two 17 drives the second sliding block 18 to slide inside the second support guide rail 14, thereby linking the second connecting plate 19, and then realizing the front and back horizontal displacement adjustment of the clamping assembly. Through the mutual cooperation of the above components, the precise installation of the bridge deck can be ensured, making the bridge structure more stable, improving the bearing capacity and service life of the bridge. Moreover, it can be accurately positioned in place at one time, reducing the time and labor input for repeated adjustment, accelerating the construction progress of the entire bridge. At the same time, the precise positioning adjustment reduces the uncertainty and occurrence of accidents during construction, ensuring the safety of construction personnel and the integrity of equipment.
