[0002] Bridge support brackets are the foundation of mobile formwork bridge-building machines. They mainly serve a supporting function to ensure the stability and safety of bridge construction. There are various structural forms of bridge support brackets, depending on the specific construction needs and bridge type. Common structural forms include transverse cantilever triangular brackets, longitudinal cantilever triangular brackets, and front and rear limb inclined leg rigid frame brackets. These bracket structures vary, but all can meet the support needs in bridge construction.

[0003] In current bridge construction, bridge support brackets are mainly used for support and positioning of flat bridges. However, for curved bridges, traditional support brackets are difficult to provide effective support, which limits the scope of application of support brackets and needs to be improved.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, a bridge support bracket for bridge construction includes a base 1, a box 2, a flat plate support mechanism 3, a lifting platform 4, a drive mechanism 5, and an arc-shaped support mechanism 6.

[0026] like Figure 1 , Figure 2 As shown, the base 1 is horizontally positioned, and the housing 2 is vertically positioned on the base 1 with an open top. The flat plate support mechanism 3 is horizontally positioned at the opening of the housing 2 and is detachably connected to the housing 2.

[0027] like Figure 1 , Figure 2 As shown, the flat plate support mechanism 3 includes a pair of flat support plates 31, which are laid at the opening of the box body 2, and each flat support plate 31 is horizontally provided with a load-bearing plate 32.

[0028] like Figure 1 , Figure 2 As shown, slide rods 33 are horizontally slidably connected to the upper ends of both sides of the housing 2. A support side plate 34 is provided at the inner end of the slide rod 33. The lower end of the support side plate 34 is used to abut against the top of the arc-shaped bracket 62, and the upper end is used to support the end of the flat support plate 31.

[0029] like Figure 1 , Figure 2 As shown, a limiting plate 35 is provided at the outer end of the slide rod 33 to press against the outer wall of the box 2. A baffle 36 is provided on the limiting plate 35 to abut against the outer side of the flat support plate 31. A bolt 37 threaded to the box 2 is provided on the limiting plate 35.

[0030] like Figure 1 , Figure 2 As shown, the lifting platform 4 is horizontally positioned inside the housing 2 and vertically slidably connected to the housing 2. The drive mechanism 5 is used to control the vertical sliding of the lifting platform 4. The drive mechanism 5 includes a lead screw 51, a slider 52, a gear 53, a gear ring 54, and a reducer 55.

[0031] like Figure 1 , Figure 2 As shown, the lead screw 51 is vertically rotatably connected to both sides of the housing 2, and its lower end extends into the interior of the base 1. The slider 52 is located on both sides of the lifting platform 4 and is threadedly connected to the lead screw 51. The gear 53 is located at the lower end of the lead screw 51, and the gear ring 54 is rotatably connected to the interior of the base 1 and meshes with the gear 53. The reducer 55 is used to control the rotation of the gear ring 54.

[0032] like Figure 1 , Figure 2 As shown, the arc-shaped support mechanism 6 includes a support platform 61 and an arc-shaped bracket 62. The support platform 61 is horizontally arranged on the lifting platform 4, and the arc-shaped bracket 62 is arched on the support platform 61.

[0033] like Figure 1 , Figure 2 As shown, the arc-shaped bracket 62 includes a first arc-shaped support plate 63, a second arc-shaped support plate 64, and a reinforcing plate 65. The first arc-shaped support plate 63 is arched and mounted on the support platform 61. The second arc-shaped support plate 64 is located above the first arc-shaped support plate 63. The reinforcing plate 65 is zigzag-shaped and positioned between the first arc-shaped support plate 63 and the second arc-shaped support plate 64.

[0034] When support is needed for the planar bridge, the limiting plate 35 is first pushed to move the sliding rod 33 inward. At this time, the sliding rod 33 moves the supporting side plate 34 synchronously. When the limiting plate 35 presses against the side wall of the box body 2, the lower end of the supporting side plate 34 is pressed against the top of the arc-shaped bracket 62.

[0035] Then, the bolt 37 is rotated to fix the limiting plate 35. Then, a pair of flat support plates 31 are laid at the opening of the box body 2, and the sides that are close to each other are supported by the support side plate 34 respectively, while the other side abuts against the baffle 36, thereby limiting the pair of flat support plates 31 and ensuring that the force on the pair of flat support plates 31 is even, so as to support the planar bridge with a pair of flat support plates 31.

[0036] When support is needed for the arched bridge, first loosen bolt 37, then pull the limiting plate 35 to move the sliding rod 33 outward. At this time, the sliding rod 33 drives the supporting side plate 34 to move synchronously. When the supporting side plate 34 presses against the inner wall of the box body 2, then remove and unload the pair of flat support plates 31.

[0037] Then, the reducer 55 is started, which drives the gear ring 54 to rotate. With the cooperation of the gear 53, the lead screw 51 rotates stably. At this time, the lead screw 51 controls the slider 52 to slide vertically. The slider 52 drives the support platform 61 and the arc-shaped bracket 62 to move upward synchronously. After the arc-shaped bracket 62 is located outside the housing 2, it can be used to support the arc-shaped bridge.

[0038] Therefore, by setting a detachable flat plate support mechanism 3 on the top of the box body 2, it is possible to support the flat bridge after assembly. At the same time, the box body 2 is equipped with a lifting arc support mechanism 6, which can disassemble the flat plate support mechanism 3 and control the arc support mechanism 6 to rise, thereby supporting the arc bridge and improving the practicality of the entire bridge support bracket.

[0039] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
