Description

Technical Field

[0001] The present invention relates to the technical field of double-arc bridges, in particular to a double-arc bridge structure for rapid docking and assembly. Background Art

[0002] The biggest advantage of a double-arc bridge is that it improves the strength and stability of the bridge. It overcomes the weakness of general arch bridges that are prone to bending and deformation laterally under heavy pressure, and better distributes the bridge pressure throughout the bridge. In addition, a double-arc bridge can also achieve a much larger span than a general arch bridge with the same material. If the span is the same, about half of the steel and other building materials can be saved. In terms of shape, due to the two-way curvature, the double-arc bridge is more varied, more beautiful, and more stretched. The main arch ring has single wave, multiple waves, multiple waves with high and low ribs, etc. The arch rib cross-section has rectangular, inverted T-shaped, I-shaped, L-shaped, thin-walled box-shaped, etc. The hyperbolic arch bridge is an upper-supported arch bridge according to the location of its carriageway. If viewed from the cross-section of the main arch ring, it is composed of arch ribs, arch waves, arch plates, and transverse connections. Since the arch waves between the arch ribs are also curved and orthogonal to the curve of the main arch ring, it is called a double-arc bridge. During the installation and docking of the double-arc bridge, the load-bearing pressure at the top of the double-arc bridge is evenly distributed to the load-bearing columns. Therefore, the support and protection of the load-bearing columns can effectively extend the service life of the double-arc bridge. In addition to the traditional mortise and tenon connection structure, the installation of the double-arc bridge can be effectively accelerated by setting quick docking components at the docking positions on both sides of the double-arc bridge. To this end, we propose a double-arc bridge structure for rapid docking and assembly. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-arc bridge structure for rapid docking and assembly to solve the problems raised in the above background technology: By rotating the support rod inside the abutment block, the slider at the top of the abutment block moves inward, and the abutment rollers and telescopic rollers installed on the slider press the entire support plate tightly, preventing the entire bridge bottom column from shaking, which would cause the entire bridge to shake. By clamping one side of the V-shaped rod into the vertical block, the overall weight of the main connecting beam is used to drive the V-shaped rod to rotate. As the V-shaped rod rotates, it pulls the connecting teeth on the secondary connecting beam to abut against the connecting teeth on the main connecting beam, avoiding the more complicated installation problem of the double-arc bridge; To achieve the above object, the present invention provides the following technical solutions: A double-arc bridge structure for quick docking assembly includes a main connecting beam and a secondary connecting beam, secondary connecting beams are symmetrically installed on both sides of the main connecting beam, arc-shaped support frames are fixed to the bottom of the main connecting beam and the secondary connecting beam through brackets, connecting blocks are fixed to both sides of the arc-shaped support frames by bolts, locking blocks are installed on both sides of the main connecting beam and on one side of the connecting block, load-bearing columns are installed at the bottom of the locking blocks, and a stabilizing support mechanism is installed on the outer wall of the locking blocks; The sturdy support mechanism includes a square sleeve, a stop block, a stop column and a support plate, the outer wall of the locking block is fixed with a square sleeve by a bolt sleeve, and the stop block is evenly and symmetrically installed in the square sleeve, the top of the stop block is slidably connected to a slider, and one side of the slider is slidably connected to the stop column through a bearing, one side of the stop column is slidably connected to the support plate, and one side of the support plate abuts against the outer wall of the locking block, one end of the stop column is movably connected to an abutting roller through a bearing, the other end of the stop column is provided with a sliding groove, and is slidably connected to a telescopic roller in the sliding groove, one end of the telescopic roller is located in the sliding groove and is sleeved with a first spring, and the other end of the telescopic roller abuts against one side of the support plate; The inner wall of the square sleeve is movably connected to a support rod through a bearing, and a gear sleeve is fixedly mounted on the support rod, and the bottom of the sliding block is meshed and connected with the gear sleeve.

[0004] Furthermore, connecting teeth are symmetrically installed on both sides of the main connecting beam and the secondary connecting beam, and the connecting teeth on one side of the main connecting beam and the secondary connecting beam are interlaced and abutted. Vertical blocks are evenly fixed on both sides of the bottom of the secondary connecting beam by bolts, and inclined blocks are evenly slidably connected on both sides of the bottom of the main connecting beam.

[0005] Furthermore, abutment grooves are evenly and symmetrically provided on both sides of the locking block, and a V-shaped rod is rotatably connected in the abutment groove through a bearing, one end of the V-shaped rod is slidably connected to the vertical block, and the other end of the V-shaped rod is slidably connected to the inclined block.

[0006] Furthermore, a pressure groove is provided at the top of the abutment groove, and a pressure column is slidably connected in the pressure groove, one end of the pressure column passes through the pressure groove and extends into the abutment groove, and a lock is fixed to one end of the pressure column in the abutment groove by spot welding, and a second spring is symmetrically sleeved and connected on the outer wall of the pressure column in the pressure groove.

[0007] Furthermore, a cam is fixed to one side of the V-shaped rod in the pressure groove by spot welding, and one side of the cam abuts against the top of the pressure column, and a limiting shell is symmetrically fixed in the abutting groove by bolts.

[0008] Furthermore, one side of the connecting block is evenly fixed to the limiting shell by bolts, and a semicircular block is movably connected inside the limiting shell, and a square lock hole is opened on the top of the semicircular block.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by rotating the support rod located in the abutment block, the slider located at the top of the abutment block moves inward, and the abutment rollers and telescopic rollers installed on the slider press the entire support plate tightly, so that the square sleeve presses and supports the entire locking block tightly, thereby stabilizing the entire load-bearing column and avoiding the problem of the load-bearing column shaking and damage caused by the heavy load of the entire bridge. The V-shaped rod is connected to the vertical block by clamping one side of the V-shaped rod into the vertical block, and the overall weight of the main connecting beam is used to drive the V-shaped rod to rotate. While the V-shaped rod rotates, the connecting teeth on the secondary connecting beam are pulled to abut against the connecting teeth on the main connecting beam, finally completing the splicing of the main connecting beam and the secondary connecting beam. When the V-shaped rod rotates, the connecting block connected to one end of the secondary connecting beam and the main connecting beam enters the abutting groove in the locking block, so that the limiting shells at the ends of the main connecting beam and the secondary connecting beam are clamped with the limiting shells in the abutting groove, so that the semicircular block located in the limiting shell rotates. When the square lock holes on the semicircular block coincide with each other, the rotation of the V-shaped rod drives the cam in the pressing groove to rotate, and the rotation of the cam presses the pressing column downward, so that the lock head at the end of the pressing column enters the square lock hole, completing the locking and clamping of the connecting block between the main connecting beam and the secondary connecting beam, and the overall installation of the main connecting beam and the secondary connecting beam is more convenient.

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] See also Figure 1-7 , the present invention provides a technical solution: Example 1 like Figure 1 As shown, the entire double-arc bridge structure for quick docking assembly is divided into a main connecting beam 1 and a secondary connecting beam 2. Since the main connecting beam 1 and the secondary connecting beam 2 are installed in a docking manner, if the entire bridge body length is extended, a main-secondary connection method can be used. The main connecting beam 1 is installed with two more load-bearing columns 5 than the secondary connecting beam 2. The entire load-bearing column 5 is divided into the column body itself, which is cast with reinforced concrete, and a locking block 6 is installed on the top of the load-bearing column 5. The locking block 6 is made of basic open-hearth killed steel, which has good welding performance and low notch sensitivity. Figure 7 As shown, abutment grooves 22 are symmetrically opened on both sides of the locking block 6, and a limiting shell 18 is fixed in the abutment groove 22 by bolts. A rotatable semicircular block 19 is provided in the limiting shell 18, and a square lock hole 20 is installed on the semicircular block 19. When the connecting block 21 connecting one side of the main connecting beam 1 and the secondary connecting beam 2 enters the abutment groove 22, the limiting shell 18 on the connecting block 21 will be spliced ​​with the limiting shell 18 in the abutment groove 22, causing the semicircular blocks 19 in the two limiting shells 18 to abut and rotate, and at the same time, the square lock holes 20 on the semicircular blocks 19 coincide with each other; like Figure 6As shown, a pressure groove 14 is correspondingly provided in the entire locking block 6 and at the top of the abutting groove 22, and a pressure column 15 is slidably connected in the pressure groove 14. One end of the entire pressure column 15 passes through the pressure groove 14 and enters the abutting groove 22. In order to prevent the pressure column 15 from obstructing the entry of the connecting block 21 in the abutting groove 22, the entire pressure column 15 is sleeved and installed with a second spring 16 in the pressure groove 14. The elasticity of the second spring 16 is used to lift the entire pressure column 15. A cam 13 is installed on the top of the pressure column 15, and the cam 13 is connected to the V-shaped rod 10 installed on the top of the locking block 6. , causing the entire V-shaped rod 10 to rotate and drive the cam 13 to rotate, and the rotation of the cam 13 presses the pressure column 15 in the pressure groove 14, so that the lock head 17 fixed at one end of the pressure column 15 enters the abutment groove 22. When the limiting shells 18 on both sides of the abutment groove 22 abut, the semicircular block 19 on the limiting shell 18 overlaps and rotates, causing the square lock hole 20 to rotate and correspond to the lock head 17 installed at the bottom of the pressure column 15. At this time, the descent of the pressure column 15 will cause the lock head 17 to enter the square lock hole 20 on the semicircular block 19, thereby locking the entire limiting shell 18. When the entire double-arc bridge structure is butted, the vertical block 11 on the secondary connecting beam 2 first contacts the V-shaped rod 10. When the inclined block 12 on one side of the entire main connecting beam 1 contacts the other side of the V-shaped rod 10, the end of the V-shaped rod 10 has a larger range of movement in the inclined block 12 than the vertical block 11. After the inclined block 12 on the entire main connecting beam 1 contacts one side of the V-shaped rod 10, the entire main connecting beam 1 presses down the V-shaped rod 10 by its own weight, causing the entire inclined block 12 to move. At the bottom of the main connecting beam 1, the other end of the entire V-shaped rod 10 rotates to drive the vertical block 11 at the bottom of the secondary connecting beam 2 and the body of the secondary connecting beam 2 to move toward the side of the main connecting beam 1. Since the entire inclined block 12 can move at the bottom of the main connecting beam 1, the inclined block 12 increases the range of movement of the end of the V-shaped rod 10 compared to the vertical block 11, thereby achieving the entire main connecting beam 1 remaining stationary while the entire secondary connecting beam 2 moves toward the main connecting beam 1, completing the splicing operation of the main connecting beam 1 and the secondary connecting beam 2; A connecting tooth 4 is installed on one side of the entire main connecting beam 1 and the secondary connecting beam 2. After the main connecting beam 1 and the secondary connecting beam 2 are spliced, there is a gap between the connecting teeth 4 on both sides. On the one hand, it is convenient for the drainage of water on the bridge surface. On the other hand, due to the thermal expansion and contraction of metal materials, it prevents the metal bridge that is completely spliced ​​without leaving any gaps from cracking at the splicing due to the high temperature of the bridge surface, which may cause serious damage to the bridge.

[0014] Example 2 Since there are many components installed on the entire locking block 6, in order to avoid damage to the locking block 6, the outer side of the locking block 6 is reinforced by stabilizing the supporting mechanism 7 as a whole. Figure 2-4 As shown, the square sleeve 701 on the entire arc-shaped support frame 3 fully wraps the entire locking block 6, and support plates 707 are symmetrically installed on both sides of the square sleeve 701, as shown in FIG. Figure 3 As shown, one side of the entire support plate 707 is slidably connected to the support column 704, and the entire support column 704 is triangular in shape. A rolling contact roller 705 is installed at one end of the support column 704, and a retractable retractable roller 706 is installed at the other end of the support column 704. Figure 4 As shown, a slide groove 708 is provided on one side of the entire support column 704, and a first spring 709 is installed in the slide groove 708, and the telescopic movement of the entire telescopic roller 706 is achieved by the first spring 709; The entire block 702 is movably connected to a support rod 8 through a bearing, and a gear sleeve 9 is fixedly connected to the support rod 8. When the entire support rod 8 moves outward, the rotation of the support rod 8 drives the gear sleeve 9 to rotate, causing the entire gear sleeve 9 to rotate counterclockwise and push the slider 703 to move inward, causing the slider 703 to press the telescopic roller 706 and cause the abutment roller 705 to move upward, further pressing against the support plate 707 on one side of the locking block 6, further locking the entire locking block 6.

[0015] The installation method of the present invention: First, align the connecting block 21 on one side of the entire secondary connecting beam 2 with the abutment groove 22 on one side of the locking block 6, and make the limiting shell 18 on the connecting block 21 engage with the limiting shell 18 in the abutment groove 22. At the same time, rotate the V-shaped rod 10 at the top of the locking block 6 so that one end of the V-shaped rod 10 is engaged with the vertical surface block 11. At this time, the connecting block 21 on one side of the entire main connecting beam 1 is placed into the abutment groove 22 in the locking block 6, so that the two limiting shells 18 are also abutted. When the entire main connecting beam 1 side enters the abutment groove 22, the inclined block 12 at the bottom of the main connecting beam 1 abuts against one side of the V-shaped rod 10, and drives the entire V-shaped rod 10 to rotate. After the V-shaped rod 10 rotates, it pulls the entire secondary connecting beam 2 toward the side of the main connecting beam 1, so that the limiting shell 18 on one side of the secondary connecting beam 2 is completely pressed against the limiting shell 18 in the abutment groove 22. At the same time, the rotation of the entire V-shaped rod 10 drives the top connecting tooth 4 of the secondary connecting beam 2 to engage with the upper connecting tooth 4 of the main connecting beam 1, completing the assembly of the entire main connecting beam 1 and the secondary connecting beam 2. At the same time, the square sleeve 701 is sleeved on the locking block 6 by means of bolts, the support columns on both sides of the load-bearing column 5 are unfolded, and one end of the support rod 8 is fixed by means of bolts.
