Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] The features and performance of the bridge construction support bracket device of this application will be further described in detail below with reference to the embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this application embodiment provides a bridge construction support bracket device, which includes a first fixed plate 100, four casters 110 installed at the bottom of the first fixed plate 100, two columns 120 fixedly installed at the top of the first fixed plate 100, and a support assembly 200 disposed at the top of the first fixed plate 100. The support assembly 200 includes a liftable support plate 210 and a lifting mechanism for driving the support plate 210 to rise and fall. The lifting mechanism includes a bidirectional screw 220 rotatably connected to the two columns 120 at both ends, a movable seat 230 threadedly sleeved at both ends of the bidirectional screw 220, a fixed seat 240 connected to the bottom of the support plate 210, two support rods 250, and a lifting motor 260 for driving the bidirectional screw 220 to rotate. One end of 250 is hinged to two movable seats 230 respectively, and the other end is hinged to a fixed seat 240 respectively. The column 120 is connected to a support plate 270 and a second fixed plate 280 with its two ends connected to the corresponding column 120 and support plate 270 respectively. The lifting motor 260 is fixed on the support plate 270. One end of the bidirectional screw 220 is rotatably inserted through the corresponding column 120 and connected to the output shaft of the lifting motor 260. The bottom of both ends of the support plate 210 is connected to guide rods 130 that are slidably inserted into the top of the two columns 120 respectively. The two ends of the support plate 210 are connected to rotatable shafts 290 respectively. Each shaft 290 is connected to an end extension plate 420. The shaft 290 extends along the width direction of the support plate 210. The two end extension plates 420 are symmetrically arranged at both ends of the support plate 210.

[0025] The first fixed plate 100 has liftable fixed blocks 300 at both ends, and three fixing teeth 310 at the bottom of each fixed block 300. The support plate 210 is connected to two fixed blocks 300 at both ends via a linkage mechanism. The linkage mechanism is used to lower the corresponding fixed block 300 when the support plate 210 is raised, causing the fixing teeth 310 to insert into the ground for fixation. The linkage mechanism includes a sealing box 320 fixed to the first fixed plate 100. A partition 330 is provided inside the sealing box 320, which holds the sealing box 320 in place. The internal partition is divided to form a first piston chamber 340 and a second piston chamber 350 arranged to the left and right. The first piston chamber 340 and the second piston chamber 350 are respectively provided with a liftable first piston 360 and a second piston 370. The bottom of the first piston 360 and the corresponding fixed block 300 are connected by a first connecting rod 380. The top of the second piston 370 and the support plate 210 are connected by a second connecting rod 390. The top of the partition 330 is provided with a first channel 400 that connects the first piston chamber 340 and the second piston chamber 350.

[0026] When using the bridge construction support bracket device provided in this embodiment, the worker first moves the first fixed plate 100 and the support plate 210 below the position to be supported by using the casters 110 installed at the bottom of the first fixed plate 100. Then, the lifting mechanism drives the support plate 210 to rise for support. At this time, the lifting motor 260 is started and drives the bidirectional screw 220 to rotate through the output shaft. When the bidirectional screw 220 rotates, it drives the movable seats 230, which are respectively threaded onto both ends of the bidirectional screw 220, to move towards each other. This causes the two support rods 250, which are respectively hinged to the two movable seats 230, to rotate. This causes the fixed seats 240, which are hinged to the other ends of the two support rods 250, to rise, thereby pushing the support plate 210 to rise for support and operation. When the support plate 210 rises, the linkage mechanism drives the two corresponding fixed blocks 300 to fall until the two fixed blocks are lowered. The fixing teeth 310 connected to the bottom of the fixed block 300 are inserted into the ground for fixation, thereby achieving an automatic fixing function. Specifically, when the support plate 210 is raised, it drives the two second connecting rods 390 connected to the bottom of both ends to rise. When the two second connecting rods 390 are raised, they drive the two second pistons 370 to move upward along the second piston chamber 350, respectively, to compress the gas in the top of the first piston chamber 340, the top of the second piston chamber 350, and the first channel 400. The pressure of the compressed gas pushes the first piston 360 to move downward along the first piston chamber 340. Then, the first piston 360 pushes the first connecting rod 380 and the corresponding fixing block 300 downward, so that the fixing teeth 310 connected to the bottom of the fixing block 300 are inserted into the ground for fixation, stably fixing the position of the first fixing plate 100 and ensuring that the support plate 210 of the bridge construction support bracket device is stably supported.

[0027] The support plate 210 has guide rods 130 at both ends of its bottom connected to the tops of two columns 120, which are slidably inserted into the tops of the columns 120. These guide rods 130 can be moved up and down to insert into or disengage from the columns 120 when the support plate 210 is raised or lowered, thus improving the stability of the support plate 210. The support plate 210 has rotatable shafts 290 at both ends of its bottom. Each shaft 290 is connected to an end extension plate 420. The shafts 290 extend along the width of the support plate 210. The two end extension plates 420 are symmetrically arranged at both ends of the support plate 210. Workers can rotate the end extension plates 420 at both ends of the support plate 210 relative to the shafts 290, thereby increasing the support range of the support plate 210 and using the end extension plates 420 to assist in the support operation.

[0028] like Figure 6As shown, in some optional embodiments, the linkage mechanism is used to drive the corresponding fixing block 300 to descend or rise when the support plate 210 rises or falls, so that the fixing tooth 310 is inserted into the ground for fixing or detached from the ground. In this case, the structure of the linkage mechanism, based on the structure disclosed in the above embodiments, further includes: the bottom of the partition plate 330 is provided with a second channel 410 connecting the first piston chamber 340 and the second piston chamber 350, which can drive the two second connecting rods 390 connected to the bottom of both ends to descend when the support plate 210 descends, and when the two second connecting rods 390 descend, they drive the two second pistons 370 respectively. The gas in the bottom of the first piston chamber 340, the bottom of the second piston chamber 350, and the second channel 410 is compressed by moving downward along the second piston chamber 350. The pressure of the compressed gas pushes the first piston 360 upward along the first piston chamber 340. The first piston 360 then drives the first connecting rod 380 and the corresponding fixing block 300 upward, causing the fixing tooth 310 connected to the bottom of the fixing block 300 to detach from the ground and release the fixing. This unlocks the position of the first fixing plate 100, making it easier for workers to push the bridge construction support bracket device to the next work site for support work.

[0029] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
