[0001] The utility model relates to the technical field of building construction, in particular to a movable anti-throwing net for bridge construction. Background Art

[0002] The bridge anti-throwing net (also known as the bridge protection net and the bridge guardrail net) is made of high-quality low-carbon steel wire through a series of processes such as drawing, weaving, welding, and plastic dipping.

[0003] Currently, when constructing a bridge, the anti-throwing net is generally fixed at the edge position of the bridge for protection during the construction process. However, when moving to the next bridge section after the construction of this bridge section is completed, since the anti-throwing net is in a fixed state, it is rather troublesome to disassemble. Then, when reaching the next bridge section, it is necessary to fix and install it again. This process is rather cumbersome, not only time-consuming and laborious, but also has low operational practicability.

[0004] Therefore, it is necessary to provide a new movable anti-throwing net for bridge construction to solve the above technical problems. Summary of the Utility Model

[0007] Preferably, the installation frame is in a "U" shape, and the lengths of the two side bars at both ends of the installation frame are different, and the length of the right side bar of the installation frame is greater than the length of the left side bar.

[0008] Preferably, the positioning frame is also in a "U" shape, and the distance between the two ends of the "U" shape of the positioning frame is equal to the width of the anti-throwing net, and the lengths of both ends of the installation frame are equal to the width of the anti-throwing net.

[0009] Preferably, one end of the rolling ball leaks out to the left outside the side wall of the bottom end of the positioning frame, and the bottom end of the positioning frame is fixedly connected to the support rod at the right end of the mounting frame through the positioning block, and the height of the positioning frame is less than the length of the support rod at the right end of the mounting frame.

[0010] Preferably, the limiting structure further includes a screw rod, a sliding rod, a fixing frame and a first roller.

[0013] The present invention provides a movable anti-throwing net for bridge construction. Firstly, the U-shaped mounting frame can straddle the periphery of the bridge side wall. The second roller installed on the left side abuts against the surface of the bridge, and the right side is suspended outside the bridge. The bottom surface of the top end abuts against the top surface of the bridge side wall through the second roller. Then, by rotating the limiting structure, one end of it is driven to lean against the inner side wall of the bridge side wall. As the screw rod in the limiting structure rotates, one end of the limiting structure pushes the inner side wall of the bridge side wall. Under the reaction force, the limiting structure pushes the mounting frame to adjust its position, so that one end of the mounting frame on the outer side wall of the bridge abuts against the outer side wall of the bridge through the second roller, and the limiting structure restricts the position of the mounting frame. Under the fixation of the positioning structure, the anti-throwing net vertically encloses the periphery of the bridge. Furthermore, under the action of the first roller and the second roller, the device can slide along the side wall of the bridge arbitrarily. This device has the advantage of being convenient to move along with the position of the construction section during the construction process. Description of the Drawings

[0021] During the specific implementation process, as Figure 1 , Figure 2 and Figure 4 shown, the shape of the mounting frame 3 is "U" shaped, and the lengths of the two side bars of the mounting frame 3 are different, and the length of the right side bar of the mounting frame 3 is greater than the length of the left side bar; the shape of the positioning frame 21 is also "U" shaped, and the distance between the two ends of the "U" shape of the positioning frame 21 is equal to the width of the anti-throwing net 1, and the lengths of both ends of the mounting frame 3 are equal to the width of the anti-throwing net 1.

[0022] It is convenient to weld and fix the anti-throwing net 1 through the positioning frame 21, so that the mounting frame 3 can support the anti-throwing net 1 through the positioning frame 21.

[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, one end of the rolling ball 23 leaks out to the left outside the side wall of the bottom end of the positioning frame 21, and the bottom end of the positioning frame 21 is fixedly connected to the support rod at the right end of the mounting frame 3 through the positioning block 22, and the height of the positioning frame 21 is less than the length of the support rod at the right end of the mounting frame 3.

[0024] It is convenient to make the positioning frame 21 contact with the outer side wall of the bridge 6 through the rolling ball 3 at the bottom end, so that the bottom end of the positioning frame 21 can be supported by the outer side wall of the bridge 6.

[0025] In the specific implementation process, such as Figure 1 、 Figure 2 and Figure 4 As shown, the limiting structure 4 further includes a screw rod 41, a sliding rod 42, a fixing frame 43 and a first roller 44.

The first roller 44 is installed at the upper and lower ends of the fixing frame 43. The sliding rod 42 is horizontally fixed to the back of the upper and lower ends of the fixing frame 43. The length of the sliding rod 42 corresponds to the length of the screw rod 41, and the sliding rod 42 is parallel to the screw rod 41. The other end of the sliding rod 42 penetrates through the side wall of the left support rod of the mounting frame 3, and the sliding rod 42 slides on the side wall of the left support rod of the mounting frame 3.

[0026] By rotating the screw rod 41, it is convenient to drive the fixing frame 43 to displace, and then drive the first roller 44 to adjust its position, so that the first roller 44 can support on the inner side wall of the side wall at the edge of the bridge 6, thereby limiting the position of the device.

[0027] The working principle of the movable anti-throwing net for bridge construction provided by the present utility model is as follows:

[0028] During use, first weld and fix the anti-throwing net 1 on the inner side wall of the positioning frame 21, then install the mounting frame 3 on the side wall of the bridge 6, with the short end of the support rod facing the inside of the bridge 6. Then, by rotating the screw rod 41, drive the fixed frame 43 to push the first roller 44 to move until it abuts against the inner side wall of the side wall of the bridge 6, so that the screw rod 41 is supported by the first roller 44. The right end of the mounting frame 3 abuts against the outer side wall of the bridge 6 through the second roller 5, the left end of the mounting frame 3 abuts against the surface of the bridge 6 through the second roller 5, and the bottom surface of the top end of the mounting frame 3 is supported on the top surface of the side wall of the bridge 6 through the second roller 5, so that the position of the mounting frame 3 is restricted under the support of the screw rod 41. Then, according to the distance between the support rod at the right end of the mounting frame 3 and the side wall of the bridge 6, make the bottom end of the positioning frame 21 abut against the outer side wall of the side wall of the bridge 6 through the rolling ball 23, and then weld and fix its top end on the bottom surface of the top end of the installation. Weld through the positioning block 22 on the side walls of the bottom ends of the positioning frame 21 and the mounting frame 3, so that the positioning frame 21 can be more firmly fixedly connected with the mounting frame 3, and the anti-throwing net 1 can be firmly enclosed on the outer side wall of the bridge 6. This device has the advantage of being easy to move along with the position of the construction section during the construction process.

[0029] Compared with the related technology, the movable anti-throwing net for bridge construction provided by the present invention has the following beneficial effects:

[0030] The present invention provides a movable anti-throwing net for bridge construction. First, the U-shaped mounting frame 3 can straddle the periphery of the side wall of the bridge 6. Its left side abuts against the surface of the bridge 6 through the second roller 5 installed, and its right side hangs on the outside of the bridge 6. The bottom surface of its top end abuts against the top surface of the side wall of the bridge 6 through the second roller 5. Then, by rotating the limiting structure 4, drive one end of it to lean towards the inner side wall of the side wall of the bridge 6. As the screw rod 41 in the limiting structure 4 rotates, one end of the limiting structure 4 pushes the inner side wall of the side wall of the bridge 6. Under the reaction force, the limiting structure 4 pushes the mounting frame 3 to adjust its position, so that one end of the mounting frame 3 on the outer side wall of the bridge 6 abuts against the outer side wall of the bridge 6 through the second roller 5, and the limiting structure 4 restricts the position of the mounting frame 3. Under the fixation of the positioning structure 2, the anti-throwing net 1 vertically encloses the periphery of the bridge 6. Furthermore, under the action of the first roller 44 and the second roller 5, the device can slide arbitrarily along the side wall of the bridge 6. This device has the advantage of being easy to move along with the position of the construction section during the construction process.
