Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a fast-installed and disassembled protective device for a cross-line bridge. Background Art

[0002] Traditionally, installing protective devices on cross-line bridges requires occupying the driving lane, especially for protection over highways, which usually requires occupying the overtaking lane and emergency lane, posing a high safety risk when vehicles pass through. In recent years, the bottom plate of the cross-line bridges undertaken by the company is 5.7 to 6.1 meters above the road surface, and the installation of protective devices must ensure a passing height of 5 meters. Under such working conditions, traditional protective devices have no construction space on the upper part, and lifting equipment cannot be well utilized during dismantling. The long dismantling period affects traffic and has a high construction safety risk.

The substantial technical effect and the realization process of the technical solution here, i.e. the basic functions, are as follows: the overall structure is semi-portal, and the main structure is an L-shaped bracket; the semi-portal structure uses the bracket of the central isolation belt as support so as not to occupy the overtaking lane; the use of directional pulleys can quickly move from under the bridge to a site with a hoisting operation space during disassembly; the L-shaped brackets are connected by bolts through diagonal braces.

[0037] Considering the above reasons, the company decided to research, design and manufacture a protective device that does not occupy the roadway and can be quickly and safely disassembled. When in use, the L-shaped bracket is connected to form a semi-portal structure through diagonal braces, and the protective plate is installed on the diagonal braces of the crossbeam;

[0038] And install edge protection nets on the crossbeams of the L-shaped brackets at both ends of the portal structure;

[0039] During disassembly, two L-shaped brackets are grouped together. After a group of devices is towed out by a winch or electric hoist, the diagonal brace connected to the next group of devices is removed. The entire group of devices is moved out of the construction road by a hoisting device and then transported to a designated site by a flatbed truck for disassembly of the entire group of devices. The next group of devices is then towed and disassembled. Compared with the prior art, this patent can avoid the impact on the road surface to the greatest extent possible. It is convenient and quick to install, and can protect the road surface and construction.

[0042] Embodiment 4: As a further improved solution or parallel solution or optional independent solution, the support part 7 supports the support cross-line construction support 6. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: the structure is used to serve the construction of cross-line bridges.

[0043] Embodiment 5: As a further improved solution or a parallel solution or an optional independent solution, the cross-line construction support 6 is used to construct the cross-line line.

[0044] Embodiment 6: As a further improved solution or a parallel solution or an optional independent solution, the width and length of the protective plate 2 are sufficient to cover the road surface of the construction cross-line line.

[0045] Embodiment 7: As a further improved solution or parallel solution or optional independent solution, an edge protection net is installed on the crossbeam of the L-shaped bracket. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: the edge protection net is used to protect roads and bridges and provide a safer environment.

[0046] Embodiment 8: As a further improved solution or a parallel solution or an optional independent solution, multiple groups of L-shaped brackets are connected by bolts through diagonal braces.

[0047] Innovatively, each of the above effects exists independently, and a set of structures can be used to combine the above results.

[0048] It should be noted that the multiple solutions provided by this patent include the basic solution itself, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
