Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, specifically a leveling device for cast-in-place box girders. Background Technology

[0002] Box girders are a type of beam used in bridge engineering. They are named for their hollow interior and box-like shape. Box girders are mainly used because the concrete in the tension zone of a rectangular beam does not contribute to the overall bending strength, so it is omitted to save concrete and reduce the self-weight of the component. Reinforced concrete box girders are divided into precast box girders and cast-in-place box girders. Cast-in-place box girders are mostly used in the construction of large continuous bridges.

[0003] During the casting process of box girders, the segmented scaffolding and in-situ casting method is generally adopted. The usual construction sequence is to first cast the bottom and web slabs, and then cast the top slab after the bottom and web slabs have reached 70% of the design strength. At the same time, before casting, the scaffolding needs to be pre-stressed and the box girder needs to be leveled, which usually refers to leveling the surface layer of the box girder.

[0004] During the pouring of the top slab of the cast-in-place box girder, in order to ensure the structural strength of the bridge and the normal drainage function of the bridge surface, it is necessary to level the concrete poured in the box girder. In the existing technology, when leveling the box girder, a metal trowel is generally used to smooth the poured concrete. However, this method is labor-intensive and the leveling effect is not good.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 4As shown in the embodiment of the present invention, a leveling device for cast-in-place box girders includes a support arm 1; an adjusting arm 2 is slidably connected inside the support arm 1; a T-shaped fixing beam 3 is fixedly connected to the top of the adjusting arm 2; a T-shaped groove is formed inside the support arm 1; the T-shaped fixing beam 3 is slidably connected inside the T-shaped groove; a fixing bolt 4 is threaded inside the support arm 1; the fixing bolt 4 is positioned at the corresponding position of the T-shaped fixing beam 3; a plurality of first connecting rods 5 are provided between the support arm 1 and the adjusting arm 2; a leveling shovel 6 is fixedly connected to the bottom of the first connecting rod 5; a meshing block 7 is fixedly connected to one side of the first connecting rod 5, and a meshing groove 8 is formed on the other side of the first connecting rod 5; the meshing block 7 and the meshing groove 8 are arranged correspondingly; a moving component is provided on the side of the support arm 1 and the adjusting arm 2 that are away from each other, and the moving component can drive the support arm 1 and the adjusting arm 2 to move together; during operation, when it is necessary to level the concrete layer at the top of the cast-in-place box girder, the moving component can be moved on the sidewalk at the boundary of the cast-in-place box girder, thereby driving the support arm 1 and the adjusting arm 2 to move together. Arm 2 moves forward together, and the concrete layer can be smoothed by the first connecting rod 5 and the leveling shovel 6, making the surface of the concrete layer smoother and improving the leveling effect. This effectively reduces the need for using a metal trowel to level the concrete, which is labor-intensive. When the width of the cast-in-place box girder is different, the fixing bolt 4 can be rotated to disengage from the T-shaped fixing beam 3, and the support arm 1 and adjusting arm 2 can be pulled to adjust the width of the leveling device. This allows the leveling device to effectively adapt to the width of the cast-in-place box girder. When the width between the support arm 1 and the adjusting arm 2 changes, the number of first connecting rods 5 can be increased or decreased. At the same time, different sizes of first connecting rods 5 can be produced during production, so that the first connecting rods 5 and the leveling shovel 6 can better adapt to the width between the support arm 1 and the adjusting arm 2. At the same time, the meshing block 7 is engaged and connected inside the meshing groove 8, which increases the contact area between each first connecting rod 5, thus making the first connecting rod 5 more stable.

[0032] like Figures 3 to 4 As shown, a supporting keel 9 is fixedly connected to the side wall of the adjusting arm 2 away from the first connecting rod 5; a keel groove 901 is opened inside the supporting arm 1; the supporting keel 9 and the keel groove 901 are arranged correspondingly; during operation, when the adjusting arm 2 moves inside the supporting arm 1, the sliding of the supporting keel 9 inside the keel groove 901 makes the adjusting arm 2 more stable when sliding inside the supporting arm 1. At the same time, the supporting keel 9 is supported by the keel groove 901, which makes the strength between the supporting arm 1 and the adjusting arm 2 greater, thereby making the structure of the supporting arm 1 more stable.

[0033] like Figure 1 , Figure 5 and Figure 7 As shown, the moving assembly includes a fixed frame 10; an electric actuator is fixedly connected to the top of the fixed frame 10; a second connecting rod 11 is fixedly connected to the output end of the electric actuator; a lifting block 12 is fixedly connected to the end of the second connecting rod 11; multiple rotating rods 131 are rotatably connected inside the lifting block 12; both ends of the rotating rods 131 are fixedly connected to forward wheels 13; the forward wheels 13 are positioned at the corresponding bottom sidewalls of the lifting block 12; transmission wheels 151 are fixedly connected to the rotating rods 131; a drive wheel 14 is rotatably connected inside the lifting block 12; the rotation of the drive wheel 14 is driven by a motor; a transmission belt 15 connects the drive wheel 14 and each transmission wheel 151; a positioning rod 16 is fixedly connected to the top of the lifting block 12; the... The positioning rod 16 is slidably connected inside the fixed frame 10. During operation, when it is necessary to move the support arm 1 and the adjusting arm 2, the motor can drive the drive wheel 14 to rotate, which in turn drives the forward wheel 13 to rotate through the first connecting rod 5, thus moving the support arm 1 and the adjusting arm 2 forward. When it is necessary to adjust the height of the support arm 1 and the adjusting arm 2, the electric push rod can drive the second connecting rod 11 to slide up and down, which in turn drives the lifting block 12 to slide up and down, thereby achieving the adjustment of the height of the support arm 1 and the adjusting arm 2. During the up and down sliding of the lifting block 12, the fixed frame 10 restricts the positioning rod 16, which reduces the tilting of the lifting block 12 during the sliding process, thus making the sliding of the lifting block 12 more stable.

[0034] like Figures 2 to 4 As shown, both the support arm 1 and the adjusting arm 2 are rotatably connected to adjusting columns 17. The adjusting columns 17 are located on the side walls of the support arm 1 and the adjusting arm 2, which are far apart from each other. One of the adjusting columns 17 has a meshing block 7 fixedly connected to its end, and the other adjusting column 17 has a meshing groove 8 at its end. Both the meshing block 7 and the meshing groove 8 are located at the positions corresponding to the first connecting rod 5. The adjusting column 17 is internally threaded with a fixing rod 171. The fixing rod 171 is located at the position corresponding to the side wall of the adjusting arm 2. During operation, when smoothing the concrete layer, rotating the adjusting column 17 can drive the first connecting rod 5 to rotate, thereby adjusting the angle of the leveling shovel 6. This improves the smoothing effect of the leveling shovel 6 on the concrete layer. After adjustment, the fixing rod 171 can be rotated so that the end of the fixing rod 171 presses against the side wall of the adjusting arm 2, thereby fixing the leveling shovel 6.

[0035] like Figure 1 and Figure 6As shown, a support column 18 is fixedly connected to the top of the support arm 1; a transparent cover 19 is fixedly connected to the top of the support column 18; a rotating ball 20 is ball-connected inside the support column 18; a connecting rod 21 is fixedly connected to the bottom of the rotating ball 20; a counterweight 22 is threadedly connected to the end of the connecting rod 21 away from the rotating ball 20; during operation, before the support arm 1 and the adjusting arm 2 level the concrete layer, if the support arm 1 and the adjusting arm 2 tilt, the rotating ball 20 will rotate inside the support column 18. By observing whether the marked point set on the top of the rotating ball 20 stays inside the marked circle set on the top of the transparent cover 19, it can be determined whether the support arm 1 and the adjusting arm 2 are tilted.

[0036] like Figure 7 As shown, an anti-slip pad 23 is fixedly attached to the surface of the forward wheel 13; the anti-slip pad 23 is provided on the surface of each forward wheel 13; during operation, as the forward wheel 13 drives the support arm 1 and the adjusting arm 2 to move forward, by providing the anti-slip pad 23 on the surface of the forward wheel 13, the contact area between the forward wheel 13 and the road surface can be increased, thereby increasing the friction between the forward wheel 13 and the road surface, and making the forward wheel 13 drive the support arm 1 and the adjusting arm 2 forward more effectively.

[0037] like Figure 8 As shown, anti-slip grooves 24 are provided on the side walls of both the support arm 1 and the adjusting arm 2; the interior of the anti-slip grooves 24 is roughened; the anti-slip grooves 24 are provided at the positions corresponding to the fixing rod 171; during operation, when the adjusting column 17 is fixed by the fixing rod 171, the anti-slip grooves 24 on the side walls of the support arm 1 and the adjusting arm 2 can increase the contact area between the fixing rod 171 and the side walls of the support arm 1 and the adjusting arm 2, thereby making the fixing effect of the fixing rod 171 on the adjusting column 17 better.

[0038] like Figure 8 As shown, an anti-detachment block 25 is fixedly connected to the side wall of the adjusting column 17; anti-detachment grooves are provided inside both the support arm 1 and the adjusting arm 2; the anti-detachment block 25 is located inside the anti-detachment groove; during operation, when the adjusting column 17 rotates, the anti-detachment groove restricts the anti-detachment block 25, which can effectively prevent the adjusting column 17 from detaching from the support arm 1 and the adjusting arm 2, and at the same time, it can make the rotation of the adjusting column 17 more stable when it rotates inside the anti-detachment block 25.

[0039] like Figure 8As shown, multiple anti-wear beads 26 are provided between the anti-detachment block 25 and the support arm 1 and the adjusting arm 2; the anti-wear beads 26 are in contact with the side wall of the anti-detachment block 25; during operation, when the anti-detachment block 25 rotates inside the anti-detachment groove, by providing anti-wear beads 26 between the anti-detachment block 25 and the anti-detachment groove, the sliding friction between the anti-detachment block 25 and the anti-detachment groove can be changed into rolling friction, making the friction between the anti-detachment block 25 and the anti-detachment groove smaller, effectively reducing the wear between the anti-detachment block 25 and the anti-detachment groove.

[0040] like Figure 8 As shown, a rubber pad 27 is fixed to the top of the T-shaped fixing beam 3; the rubber pad 27 is set at the position of the corresponding fixing bolt 4; during operation, when the fixing bolt 4 fixes the T-shaped fixing beam 3, by setting the rubber pad 27 on the top of the T-shaped fixing beam 3, the contact area between the fixing bolt 4 and the T-shaped fixing beam 3 can be increased, so that the fixing bolt 4 fixes the T-shaped fixing beam 3 better.

[0041] During operation, when leveling the concrete layer at the top of the cast-in-place box girder, the movable component can be moved along the walkway at the boundary of the cast-in-place box girder, thereby moving the support arm 1 and the adjusting arm 2 forward together. The first connecting rod 5 and the leveling shovel 6 can then be used to smooth the concrete layer, resulting in a smoother surface and better leveling effect. This effectively reduces the need for labor-intensive methods like using metal trowels. When the width of the cast-in-place box girder varies, the fixing bolt 4 can be rotated to detach it from the T-shaped fixing beam 3, allowing the support arm 1 and the adjusting arm 2 to be pulled. The section arm 2 adjusts the width of the leveling device, allowing it to effectively adapt to the width of the cast-in-place box girder. When the width between the support arm 1 and the adjusting arm 2 changes, the number of first connecting rods 5 can be increased or decreased. Furthermore, different sizes of first connecting rods 5 can be produced during their manufacturing process. This allows the first connecting rods 5 and the leveling shovel 6 to better adapt to the width between the support arm 1 and the adjusting arm 2. Simultaneously, the meshing block 7 engages with the meshing groove 8, increasing the contact area between each first connecting rod 5 and thus improving its stability.

[0042] When the adjusting arm 2 moves inside the support arm 1, the sliding of the supporting keel 9 inside the keel groove 901 makes the adjusting arm 2 more stable when sliding inside the support arm 1. At the same time, the support keel 9 is supported by the keel groove 901, which makes the strength between the support arm 1 and the adjusting arm 2 greater, thereby making the structure of the support arm 1 more stable.

[0043] When it is necessary to move the support arm 1 and the adjusting arm 2, the motor can drive the drive wheel 14 to rotate, which in turn drives the forward wheel 13 to rotate through the first connecting rod 5, thus moving the support arm 1 and the adjusting arm 2 forward. When it is necessary to adjust the height of the support arm 1 and the adjusting arm 2, the electric push rod can drive the second connecting rod 11 to slide up and down, which in turn drives the lifting block 12 to slide up and down, thereby achieving the adjustment of the height of the support arm 1 and the adjusting arm 2. During the up and down sliding of the lifting block 12, the positioning rod 16 is restricted by the fixed frame 10, which can reduce the tilting of the lifting block 12 during the sliding process, thus making the sliding of the lifting block 12 more stable.

[0044] When smoothing the concrete layer, rotating the adjusting column 17 can drive the first connecting rod 5 to rotate, thereby adjusting the angle of the leveling shovel 6, so that the leveling shovel 6 can smooth the concrete layer better. After adjustment, the fixing rod 171 can be rotated so that the end of the fixing rod 171 presses against the side wall of the adjusting arm 2, thereby fixing the leveling shovel 6.

[0045] Before the support arm 1 and the adjusting arm 2 level the concrete layer, if the support arm 1 and the adjusting arm 2 are tilted, the rotating ball 20 will rotate inside the support column 18. By observing whether the mark point set on the top of the rotating ball 20 stays inside the mark circle set on the top of the transparent cover 19, it can be determined whether the support arm 1 and the adjusting arm 2 are tilted.

[0046] As the forward wheel 13 drives the support arm 1 and the adjusting arm 2 forward, the anti-slip pad 23 on the surface of the forward wheel 13 increases the contact area between the forward wheel 13 and the road surface, thereby increasing the friction between the forward wheel 13 and the road surface and making the forward wheel 13 drive the support arm 1 and the adjusting arm 2 forward more effectively.

[0047] When the adjusting column 17 is fixed by the fixing rod 171, the anti-slip groove 24 is opened on the side wall of the support arm 1 and the adjusting arm 2, which makes the contact area between the fixing rod 171 and the side wall of the support arm 1 and the adjusting arm 2 larger, thereby making the fixing rod 171 fix the adjusting column 17 better.

[0048] When the adjusting column 17 rotates, the anti-detachment groove restricts the anti-detachment block 25, which can effectively prevent the adjusting column 17 from detaching from the support arm 1 and the adjusting arm 2. At the same time, when the adjusting column 17 rotates inside the anti-detachment block 25, the rotation of the adjusting column 17 is more stable.

[0049] When the anti-detachment block 25 rotates inside the anti-detachment groove, the anti-wear beads 26 set between the anti-detachment block 25 and the anti-detachment groove can change the sliding friction between the anti-detachment block 25 and the anti-detachment groove into rolling friction, which makes the friction between the anti-detachment block 25 and the anti-detachment groove smaller and effectively reduces the wear between the anti-detachment block 25 and the anti-detachment groove.

[0050] When the fixing bolt 4 fixes the T-shaped fixing beam 3, by setting the rubber pad 27 on the top of the T-shaped fixing beam 3, the contact area between the fixing bolt 4 and the T-shaped fixing beam 3 can be increased, and the fixing effect of the fixing bolt 4 on the T-shaped fixing beam 3 can be better.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
