DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-3A movable bracket for erecting a bridge includes a base 1, a U-shaped frame 2 is fixedly arranged on the top of the base 1, a vertical groove 21 is opened on the side of the U-shaped frame 2, a top sealing block 13 is fixedly arranged on the top of the vertical groove 21 of the U-shaped frame 2, the top sealing block 13 is rotatably connected with a vertical screw rod 9 along the vertical direction, and a nut is arranged on the top of the vertical screw rod 9 to facilitate the use of a wrench to rotate the vertical screw rod 9.

[0022] An extension block 101 is screwed into the outer wall of the vertical screw 9, and a receiving plate 10 is fixedly provided at the other end of the extension block 101. Therefore, the height of the receiving plate 10 in the vertical direction can be changed by rotating the vertical screw 9. The receiving plate 10 is used to support the bottom of the bridge mold at different angles.

[0023] The U-shaped frame 2 is symmetrically rotated with an installation frame 12 at the bottom of the receiving plate 10, and a storage assembly is provided at the end of the rotating shaft of the installation frame 12 of the U-shaped frame 2. The storage assembly includes a rope winding wheel 8, a connecting rope 6, and a storage screw 4. The storage screw 4 is threaded into the side of the bottom connecting block 5, and the bottom connecting block 5 is fixedly connected to the side of the U-shaped frame 2.

[0024] The top of the storage screw 4 is rotatably connected to the bottom of the connecting block 3. The top of the connecting block 3 is symmetrically fixed with a connecting rope 6. The top of the connecting rope 6 can move through the guide rope block 7. The guide rope block 7 is fixedly connected to the side of the U-shaped frame 2. The guide rope block 7 is used to limit the two groups of connecting ropes 6 so that the two connecting ropes 6 can only be displaced in the vertical direction to prevent the two connecting ropes 6 from detaching from the outer wall of the rope winding wheel 8.

[0025] The top end of the connecting rope 6 is threaded into the outer wall of the rope winding wheel 8, and the rope winding wheel 8 is fixedly connected to the end of the rotating shaft of the installation frame 12. Suspension hooks 11 are equidistantly arranged on the top of the installation frame 12, and a plurality of groups of suspension hooks 11 are hung with woven nets, which are the most common green protective nets in the prior art. The suspension hooks 11 are in the shape of barbs, which are used to hang the edge of the protective net and pull the protective net to be flat.

[0026] The specific implementation steps and principles of the utility model are as follows:

[0027] When the entire device is on standby, the two groups of installation frames 12 are on the two sides of the U-shaped frame 2. At this time, a certain amount of connecting rope 6 is wound around the rope pulley 8, and a woven net is hung on the side of the installation frame 12. The storage screw 4 is continuously rotated by manpower, and the storage screw 4 drives the connecting rope 6 at the bottom of the connecting block 3 to move downward, and the connecting rope 6 thereby drives the rope pulley 8 to rotate, and the rope pulley 8 drives the two groups of installation frames 12 to be in an upward warping state.

[0028] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
