Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, a movable protection device for dismantling and recovering an existing bridge guardrail comprises two mutually parallel sliding rails 1, wherein the sliding rails 1 are arranged on the upper surface of a bridge 12 close to a side wall 13 along the length direction of the bridge 12, a support 2 is mounted on each sliding rail 1, the support 2 can move along the length direction of each sliding rail 1, specifically, the cross section of each sliding rail 1 is in an i-shaped structure, a clamping groove 3 matched with the cross section of each support is formed in the bottom end of each support 2, each clamping groove 3 is mounted on each sliding rail 1, when the movable protection device is used, a worker pushes each support 2 to move on each sliding rail 1 under the action of external force, a screw hole 4 is formed in the outer side of each clamping groove 3, a bolt 5 is mounted in each screw hole 4, and the support 2 can be fixed on the corresponding sliding rail 1 after the bolt 5 is tightened; in order to facilitate the movement of the bracket 2, a pulley 11 is arranged in the clamping groove 3, and the pulley 11 is abutted against the upper surface of the sliding rail 1, so that the friction force between the clamping groove 3 and the sliding rail 1 can be reduced during the movement.

A protective baffle 6 in an arc structure is fixed on one side of a support 2, the protective baffle 6 is made of stainless steel, the lower end of the protective baffle 6 is attached to the lower edge of the outer side of a side wall 13 of a bridge 12, the protective baffle 6 can move along with the support 2, specifically, a plurality of support rods 7 are fixed on the top of the support 2, the support rods 7 are positioned above the side wall of the bridge, one ends of the support rods 7, far away from the support 2, extend out of the side wall of the bridge and are fixed with connecting rods 8, the bottom ends of the connecting rods 8 are fixed with the protective baffle 6 in a welding mode, the protective baffle 6 is fixed in the mode, the structure of the protective baffle can prevent operators from being obstructed in dismantling operation engineering, and the working efficiency of the operators,
