Description

Technical Field

[0001] The utility model specifically relates to an anti-falling net used for a double-span bridge, and belongs to the technical field of double-span bridge structures. Background Art

[0002] In order to maintain the safety of public transportation, anti-fall nets need to be installed in some specific traffic areas. For example, an anti-fall net should be installed in the middle of a double-span bridge. The main function of the anti-fall net is to prevent fallen objects on the road from entering the drinking water protection area or other waters, and to provide certain protection for water resources. The anti-fall net is generally made of low-carbon steel wire through a series of processes such as drawing, weaving, welding, and plastic dipping. It can support fallen objects and prevent them from falling into the waters at the lower end of the double-span bridge.

[0003] For example, the announcement number is: CN220789552U, an anti-falling net for a double-span bridge, including: two anti-collision guardrails, both located on the inner side of the double-span bridge; a metal mesh, located between the two anti-collision guardrails and parallel to the bridge deck of the double-span bridge. The prior art sets two vertical anti-falling nets on two adjacent anti-collision railings, which are poor in economy, aesthetics and driving transparency. In order to solve this drawback, the utility model, starting from actual engineering applications, invents a horizontally arranged anti-falling net structure, which has the characteristics of simple structure, easy installation, economical and applicable, and does not affect driving safety and transparency.

[0004] The common anti-fall net for double-span bridges can support falling objects by setting up the anti-fall net structure, and has a simple structure and is easy to install. However, when blocking falling objects, when the weight of the falling objects is heavy, a large impact force will be generated during the falling process. The lack of a buffer structure may damage the metal mesh and cause economic losses. In addition, it is inconvenient, time-consuming and laborious for workers to remove garbage attached to the metal mesh. Utility Model Content

[0005] The utility model aims to solve the deficiencies of the prior art and provide an anti-falling net for a double-span bridge, so as to achieve the purpose of buffering falling objects and facilitating the cleaning of garbage attached to the metal mesh.

[0009] Furthermore, in order to improve the buffering effect, a first spring is sleeved on the outer side of the telescopic sleeve rod, one end of the first spring is fixedly connected to the square block, and the deformation force generated by the first spring is used to buffer the impact force generated by the falling object.

[0010] Furthermore, in order to enable the moving block to move to both sides, connecting plates are hinged on both sides of the free end of the telescopic sleeve rod, a round rod is fixedly installed between the square blocks, a moving block is sleeved on the outside of the round rod, and the other end of the connecting plate is hinged to the moving block, so that the moving block can move on the outside of the round rod.

The scraper and cleaning brush can also be manually moved to clean up the garbage attached to the metal mesh and collect it through the collection box, which is convenient, fast, time-saving and labor-saving.

[0023] See also Figure 1-Figure 6 As shown, an anti-falling net for a double-span bridge comprises two guardrails 1 located on the inner side of the double-span bridge and an installation frame 2 with a metal mesh installed inside. Angle steels 3 are symmetrically connected to the inner side of the guardrails 1 by bolts. A support plate 4 is fixedly installed at the lower end of the angle steel 3. Square blocks 5 are installed in a linear array on the upper end of the support plate 4. Limit rods 6 with threads at one end are fixedly installed on the upper ends of the square blocks 5 on both sides. The installation frame 2 is sleeved on the outer side of the limit rod 6.

When in use, the installation frame 2 is first installed between the angle steels 3 along the limiting rod 6, and then the nut 10 is rotated to limit the installation frame 2. When falling objects fall onto the metal mesh, the buffer component 7 buffers the impact force generated by the falling objects to avoid damage to the metal mesh. When the surface of the metal mesh needs to be cleaned, it can be cleaned through the cleaning component 8, and the cleaned garbage is collected by the collection box 9.

[0024] The buffer assembly 7 includes a telescopic sleeve rod 701, one end of which is fixedly mounted on the upper end of the square block 5, a square plate 702 is fixedly mounted on the free end of the telescopic sleeve rod 701, one end of the square plate 702 is in contact with the mounting frame 2, a first spring 703 is sleeved on the outer side of the telescopic sleeve rod 701, one end of the first spring 703 is fixedly connected to the square block 5, connecting plates 704 are hinged on both sides of the free end of the telescopic sleeve rod 701, a round rod 705 is fixedly mounted between the square blocks 5, a moving block 706 is sleeved on the outer side of the round rod 705, the other end of the connecting plate 704 is hinged to the moving block 706, and a second spring 70 is sleeved on the outer side of the round rod 705 7.

When in use, when the falling object falls on the metal mesh, the mounting frame 2 drives the square plate 702 to move downward, and the telescopic sleeve rod 701 contracts, driving the connecting plate 704 to move to both sides. At this time, the moving block 706 moves outside the round rod 705, squeezing the second spring 707, and the deformation force generated by the second spring 707 is used to slow down the falling speed of the falling object, which plays a certain buffering role. Then the first spring 703 is compressed, generating a reaction force to support and buffer the falling object, further improving the buffering effect.

[0026] When the utility model is in use, the installation frame 2 is first installed between the angle steels 3, and the installation frame 2 is limited by the nut 10. When objects fall onto the metal mesh, the square plate 702 moves downward, driving the connecting plate 704 to move to both sides, squeezing the second spring 707. The deformation force generated by the second spring 707 is used to slow down the falling speed of the objects, thereby playing a certain buffering role. Then the first spring 703 is compressed, generating a reaction force to support and buffer the objects, further improving the buffering effect, and avoiding damage to the metal mesh. When the surface of the metal mesh needs to be cleaned, the cleaning plate 803 is manually moved by the traction rope 804, and the garbage on the surface of the metal mesh is cleaned by the scraper 805 and cleaned into the collection box 9. At the same time, the cleaning brush 806 brushes the impurities attached to the inside of the metal mesh to improve the cleaning effect. It is convenient and fast, saving time and effort.
