Description

Technical Field

[0001] This invention belongs to the technical field of bridge construction equipment, specifically an auxiliary device for the construction of the bottom distribution beam of a precast bridge beam and its usage method. Background Technology

[0002] A bridge is generally a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient.

[0003] However, in the current technology, most bridge construction projects at home and abroad adopt the prefabricated bridge construction process. The bridges are uniformly processed in the beam yard, and after being formed, they are transported to the construction area for erection. In order to reduce transportation difficulties and costs, the prefabrication beam yard is generally selected on the road route near the bridge. However, the actual road surface is prone to varying degrees of undulation due to long-term use. When the ground of the prefabrication beam yard is not at the same elevation, the bottom of the prefabricated beam will bend and deform, and the concrete at the bottom of the prefabricated beam will be uneven. Repairing it is labor-intensive and time-consuming. In severe cases, it will directly render the prefabricated beam unusable, resulting in poor actual construction results. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device and its usage method for the construction of the bottom distribution beam of a bridge precast beam, which can effectively prevent the selected site conditions from affecting the precast beam production, while also allowing for convenient adjustment of its own structure, thereby ensuring the actual production effect of the precast beam and effectively improving the overall construction effect.

There are two sets of limiting mechanisms. Each set of limiting mechanisms includes a second support frame and a support component. There are two second support frames. A fixing frame is fixedly connected between the outer surfaces of the two second support frames. A locking block is inserted into the top of the fixing frame. A bolt is threadedly connected to one side of the outer surface of the locking block. A stop piece is slidably sleeved on the outer surface of the bolt near one edge. The support component is provided on the two second support frames.

[0006] The first connecting piece has a first connecting hole on one side of its outer surface, and the first connecting frame also has a first connecting hole on one side of its outer surface.

[0007] The connecting component includes a first rotating shaft and two mounting blocks. The two mounting blocks are fixedly connected to the outer surface of one of the first support frames. The first rotating shaft is inserted between two mounting holes. Two limiting rings are threaded to the outer surface of the first rotating shaft. A connecting worm is sleeved on the outer surface of the first rotating shaft.

[0008] Among them, the two mounting blocks are rotatably connected by a bidirectional threaded rod between their respective outer surfaces, and the outer surface of the bidirectional threaded rod is threaded with two connecting push tubes, one end of each connecting push tube slidingly through a corresponding first connecting hole.

[0009] The outer surface of the bidirectional threaded rod is fitted with a connecting worm gear, which meshes with the connecting worm.

[0010] In one group of two second support frames, a second connecting piece is fixedly connected between their opposite outer surfaces. A second connecting hole is provided on one side of the outer surface of the second connecting piece. In another group of two second support frames, a second connecting frame is fixedly connected between their opposite outer surfaces. A second connecting hole is also provided on one side of the outer surface of the second connecting frame. The interior of each second connecting hole is connected to the interior of the corresponding first connecting hole.

[0011] Each of the fixed frames has a positioning bolt threaded to one side of its outer surface, and each of the abutments has a positioning nut threaded to its outer surface. A pad is fixedly connected between the opposite outer surfaces of the two second support frames in each group, and a circular bubble level body is fixedly connected to the bottom surface inside one of the second support frames.

[0012] Each set of support components includes a top block, a second rotating shaft, and a rotating frame. The top block is fixedly connected between the opposite outer surfaces of two corresponding second support frames. A fixing block is threadedly connected to the top of each top block, and a fixing threaded hole is opened on the top of each fixing block. The second rotating shaft is rotatably connected between the opposite outer surfaces of two corresponding second support frames. A first connecting rod is inserted into one end of the second rotating shaft. An extension rod is threadedly connected to one end of the first connecting rod. A second connecting rod is threadedly connected to one end of the extension rod. An adjusting worm gear is sleeved on the outer surface of the second rotating shaft.

[0014] A method for using an auxiliary device for the construction of the bottom distribution beam of a precast bridge beam includes the following steps: S1. Splicing Setup: Based on the actual width of the precast beam, splicing is performed by adding or removing connecting mechanisms and limiting mechanisms. Multiple sets of first support frames are spliced ​​using the first connecting piece and the first connecting frame. The first rotating shaft in the corresponding connecting mechanism is rotated, which drives the corresponding bidirectional threaded rod to rotate via the connecting worm and connecting worm wheel. The rotating bidirectional threaded rod can move and adjust the position of the connecting push tube, allowing the connecting push tube to be conveniently fixedly connected to the corresponding first connecting piece, first connecting frame, second connecting piece, and second connecting frame through the corresponding first and second connecting holes. This enables rapid splicing of the connecting mechanism and limiting mechanism. S2. Structural Adjustment: By observing the body of the circular bubble level, the flatness of the equipment's location can be easily determined. Based on the actual observation results, the second rotating shaft is rotated, which in turn drives the adjusting threaded rod to rotate via the adjusting worm and adjusting worm wheel. The rotating adjusting threaded rod then drives the push block to move and adjust its position. This allows the push block to move and adjust the position of the corresponding moving block. In conjunction with the pad block, the height of the moving block can be effectively adjusted, thereby adjusting the levelness of the bottom of the precast beam mold.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, during use, the splicing process is performed by adding or removing connecting mechanisms and limiting mechanisms according to the actual width of the precast beam. Multiple sets of first support frames are then spliced ​​using the first connecting piece and the first connecting frame. By rotating the first rotating shaft in the corresponding connecting mechanism, the first rotating shaft can effectively drive the corresponding bidirectional threaded rod to rotate via the connecting worm and connecting worm wheel. This allows the rotating bidirectional threaded rod to effectively move and adjust the position of the connecting push tube. The connecting push tube can then conveniently and quickly connect the corresponding first connecting piece, first connecting frame, second connecting piece, and second connecting frame through the corresponding first and second connecting holes, thus enabling efficient and rapid splicing of the connecting mechanism and limiting mechanism. This allows the equipment to meet the needs of precast beam manufacturing of different specifications. By observing the circular bubble level, the flatness of the equipment's location can be easily determined. Based on the actual observation results, the second rotating shaft is rotated, which in turn drives the adjusting threaded rod to rotate via the adjusting worm and adjusting worm wheel. The rotating adjusting threaded rod then drives the push block to move and adjust its position. The push block can effectively move and adjust the position of the corresponding moving block, and with the help of the pad block, the height of the moving block can be effectively adjusted. This effectively adjusts the levelness of the bottom of the precast beam mold, thus effectively preventing the precast beam site from having a significant impact on the precast beam manufacturing process.

[0021] The following describes in detail the method of using an auxiliary device for the construction of the bottom distribution beam of a precast bridge beam provided in an embodiment of the present invention. The method of use includes the following steps: Step 1, Splicing Setup: Based on the actual width of the precast beam, splicing is performed by adding or removing connecting mechanism 1 and limiting mechanism 2. Multiple sets of first support frames 101 are then spliced ​​using the first connecting piece 103 and the first connecting frame 102. The first rotating shaft in the corresponding connecting mechanism 1 is rotated, allowing the first rotating shaft to effectively drive the corresponding bidirectional threaded rod 107 to rotate via the connecting worm 104 and connecting worm wheel 106. This allows the rotating bidirectional threaded rod 107 to effectively move and adjust the position of the connecting push tube 108. The connecting push tube 108 can then conveniently and securely connect the corresponding first connecting piece 103, first connecting frame 102, second connecting piece 202, and second connecting frame 203 through the corresponding first and second connecting holes. This enables rapid splicing of connecting mechanism 1 and limiting mechanism 2, allowing the equipment to meet the needs of precast beam fabrication of different specifications. Step 2, Structural Adjustment: By observing the circular bubble level body 222, the flatness of the equipment's location can be easily determined. Based on the actual observation results, the second rotating shaft 215 is rotated, which in turn drives the adjusting threaded rod 210 to rotate via the adjusting worm 216 and adjusting worm wheel 211. The rotating adjusting threaded rod 210 then drives the push block 212 to move and adjust its position. This allows the push block 212 to move and adjust the position of the corresponding moving block 214. In conjunction with the pad block 213, the height of the moving block 214 can be effectively adjusted, thereby effectively adjusting the levelness of the bottom of the precast beam mold and preventing the precast beam site from significantly affecting the precast beam manufacturing process.
