[0017] Please see Figure 1-3This utility model provides a technical solution: an adjustable height temporary support device for bridge railings, including a railing pier 1 and an adjustment mechanism 4. A fixed platform 2 is installed at the top of the railing pier 1, and a fixed rod 3 is installed at the top of each fixed platform 2. The fixed platform 2 is threadedly connected to the railing pier 1 via the fixed rods 3, and both the outer wall of the fixed rod 3 and the inner wall of the fixed platform 2 are threaded. The adjustment mechanism 4 is located at the top of the fixed platform 2, and includes an adjustment column 401, a locking rod 402, and a lifting column 403. The adjustment column 401 is located at the top of the fixed platform 2. The surface is provided with a locking rod 402, and the top of the adjusting column 401 is provided with a lifting column 403. Through the setting of the adjusting mechanism 4, when the bridge railing is temporarily supported, the height of the guardrail 6 installed at the top can be adjusted by the lifting column 403 in the adjusting mechanism 4. When adjusted to the safe design height, the height is locked by inserting the locking rod 402 on the adjusting column 401 into the hole of the lifting column 403. Then, the distance between the guardrail 6 and the guardrail pier 1 is measured with a measuring ruler, which facilitates the subsequent selection of a bridge horn guardrail bracket of appropriate height.
[0018] The top of the lifting column 403 is welded with a lower fixing ring 5. The lower fixing ring 5 forms a lifting structure with the lifting column 403 and the fixing platform 2. The lifting column 403 and the fixing platform 2 are set vertically. A guardrail 6 is installed at the top of the lower fixing ring 5.
