[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] This embodiment provides a viaduct protection installation device that crosses an existing line, such as Figure 1 As shown, it includes: a retaining ring shell 62, a hanging ear 63, a connecting ear 64, and a supporting claw 65. In this embodiment, the retaining ring shell 62 is a ring structure;

[0027] The outer side of the retaining ring housing 62 is provided with the hanging ear 63, and the hanging ear 63 is used to install the anti-throwing net;

[0028] The retainer shell 62 includes a first retainer shell and a second retainer shell; the first retainer shell can be detachably connected to the second retainer shell through the connecting ear 64, and is sleeved on the outer side of the pier;

[0029] The supporting claw 65 is a structure with multiple sections connected. Two adjacent sections of the supporting claw 65 can be detachably connected. There are multiple supporting claws 65, and the multiple supporting claws 65 are used to support the retaining ring shell 62.

[0030] Specifically, the first retaining ring shell and the second retaining ring shell are arc structures, the hanging ears 63 are respectively installed on the first retaining ring shell and the second retaining ring shell, the anti-throwing net is respectively installed on the hanging ears 63, and then the first retaining ring shell and the second retaining ring shell are installed on the bridge pier, and the connecting bolts are connected to the first retaining ring shell and the second retaining ring shell through the connecting ears 64 to form an annular structure sleeved on the bridge pier. After the connection is completed, the connection between multiple sections of the support claws 65 is carried out simultaneously in three directions, and the retaining ring shell 62 is raised linearly by manual or lifting equipment. As the retaining ring shell rises, the support claws are installed until the height of the protection structure meets the requirements of hanging the anti-throwing net, which can be changed according to the height and size of the pier structure.

[0031] In a specific embodiment, the solution of the hanging ear 63 is:

[0032] There are four hanging ears 63 in total, which are respectively arranged at the connection between the first retaining ring shell and the second retaining ring shell and are hook structures.

[0033] The four hanging ears 63 are provided to suspend the anti-throwing net at multiple points, so that the anti-throwing net is more stable after installation.

[0034] In a specific embodiment, the scheme of the connecting ear 64 is:

[0035] The connecting ear 64 includes a connecting plate 641 and a connecting bolt 642. The first retainer housing and the second retainer housing are both provided with the connecting plate 641. The connecting plate 641 is provided with a connecting through hole. The connecting bolt 642 passes through the connecting plate to connect the first retainer housing and the second retainer housing.

[0036] like Figure 1 and Figure 4 As shown, in this embodiment, three groups of connecting ears 64 are provided on the first retaining ring shell and the second retaining ring shell.

[0037] A connecting plate 641 is provided on the first retaining ring shell and the second retaining ring shell without destroying the structure of the retaining ring shell 62. The first retaining ring shell and the second retaining ring shell are connected using connecting bolts 642, which is easy to operate. Three sets of connecting ears are provided, and the structure is more stable when in use.

[0038] In a specific embodiment, Figure 1 As shown, it also includes: an anti-collision layer 61;

[0039] The anti-collision layer 61 is disposed inside the retaining ring shell 62 .

[0040] An anti-collision layer 61 is provided. During the rising process of the guard ring shell 42, the inside of the guard ring shell will generate friction with the bridge pier, thereby damaging the surface of the bridge pier. During the construction process, the anti-throwing net will move when catching objects falling from above the bridge pier, and the side of the suspension structure in contact with the bridge pier will also generate friction, thereby causing damage to the bridge pier. The provision of an anti-collision layer 61 can reduce the damage of the protective structure to the bridge pier during the overall construction process, thereby increasing the service life of the protective structure.

[0041] In a specific embodiment, the solution of the supporting claw 65 is:

[0042] The supporting claw 65 is a structure with multiple sections connected, such as Figure 2 As shown, one end of each section is a stud and the other end is a threaded hole, and the threaded hole matches the stud; two adjacent sections of the supporting claw 65 are connected by a threaded structure.

[0043] The support claw 65 is connected by a threaded structure, and the number of sections of the support claw 65 is adjusted according to the bridge pier of any height. At the same time, the connection method is to connect from the bottom to the top in sequence, which can reduce the danger of personnel installing the anti-throwing net, and the installation is simple and convenient to disassemble.

[0044] In a specific embodiment, the support claw 65 further includes a gasket 66;

[0045] like Figure 2 and Figure 3 As shown, the gasket 66 is disposed between two adjacent sections of the supporting claw 65 .

[0046] The gasket 66 is arranged between two adjacent sections of the support claw 65, which can increase the friction between the two adjacent sections of the support claw 65, improve the stability of the support claw 65, avoid wear caused by direct contact between the cross sections of the two adjacent sections of the support claw 65, avoid loose connection between the two adjacent sections of the support claw after wear, and increase the service life of the support claw 65.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
