Embodiment approach
[0036] The specific implementation method is: when the position of the cube 1 is fixed, push the fixed rod 23, the fixed rod 23 drives the fixed plate 24 to move, the fixed plate 24 drives the bolt 25 to move, and the fixed rod 23 slides inside the first bar groove 20 at the same time , the addition of the first bar-shaped groove 20 limits the movement track of the fixed rod 23, the fixed rod 23 drives the movement of the connecting block 22, and makes the connecting block 22 slide in the second bar-shaped groove 21, and the addition of the connecting block 22 makes the The connectivity between the fixed rod 23 and the square body 1 increases, the length of the first strip groove 20 is equal to the length of the second strip groove 21, and the width of the first strip groove 20 is less than the width of the second strip groove 21, so that the connecting block 22 will not slide out from the inside of the second strip groove 21. When the fixed rod 23 reaches a suitable position, ...

The invention discloses a temporary supporting devicefor rigid frame bridge beam dismantling. The device comprises a square body, a first groove is formed in the square body, a supporting block is arranged in the first groove, the supporting block penetrates through the outer wall of the square body, the supporting block is slidably connected with the square body, and a supporting rod is fixedly connected to the inner wall of the first groove; and the end, away from the first groove, of the supporting rod penetrates into the supporting block, and the supporting rod is slidably connected with the supporting block. A first stabilizing rod is arranged in a first stabilizing groove, the stability of an object is improved by adding the first stabilizing rod and a second stabilizing rod, the movement track of the second stabilizing rod is limited by adding a third stabilizing groove, the width of the first sliding groove is smaller than that of the second sliding groove, and the length of the first sliding groove is equal to that of the second sliding groove, so a second sliding block does not slide out of the second sliding groove; and a second movable rod is additionally arranged, so that a movable plate drives a connecting rod to move.
Description
technical field [0001] The invention relates to the technical field of bridge dismantling, in particular to a temporary support device for dismantling a rigid bridge. Background technique [0002] With the continuous upgrading of infrastructure, the reconstruction and expansion of bridges has become a common construction project category. For rigid frame bridges, the traditional and commonly used construction method is to erect the supporting frame system from the ground up, and then carry out the cutting and demolition construction after the bridge structure to be demolished is supported and stabilized. However, when rebuilding and expanding bridges spanning important structures, especially bridges spanning important structures such as unbroken existing pipelines, high-voltage power supply lines, expressways, ordinary railways, and high-speed rail lines, or bridges with high piers, due to space constraints or The height is too high, it is difficult to set up a support fram...
