[0002] Over the past half century, my country's railway construction has achieved remarkable progress, from "four vertical and four horizontal" to "eight vertical and eight horizontal," achieving historic success. However, due to various factors, such as increased traffic volume, increased equipment capacity, the development of new technologies, or the end of service life of earlier railway-related equipment and cables, many railways are in need of renovation and reconstruction. Due to my country's geographical conditions, numerous bridges have been built during railway construction, and during these renovations, many of these bridge supports, cables, and cable troughs require replacement.

[0003] Sound barriers are installed on railway bridges near many cities and villages. Due to the installation process of railway bridge sound barriers, the outer side of the sound barriers is relatively flat, and construction workers have no stepping position or fulcrum. There are also no good fixed points for hanging pulleys or safety ropes during construction. Therefore, the renovation and construction of equipment outside these sound barriers is difficult, there are many safety hazards, and the efficiency of the renovation and construction is relatively low.

[0004] Therefore, it is necessary to develop a special bracket specifically for the construction outside the railway bridge with a sound barrier, so as to improve the efficiency of the renovation construction of related facilities outside the railway bridge sound barrier and ensure the safety of the construction workers.

[0030] The utility model provides the following embodiments.

[0031] like Figure 1、 Figure 2 、 Figure 3 As shown, the utility model is a railway bridge sound barrier external construction pylon, comprising a first plywood assembly 1, a second plywood assembly 2, a long bolt 3 and a nut 4, wherein the first plywood assembly 1 comprises a first plywood 11, a first lifting ring 12 and a first hook 13, the first plywood 11 being a vertically arranged angle steel, a first lifting ring 12 being fixed to the middle of one waist plate of the first plywood 11, a lifting ring hole 14 being provided on the first lifting ring 12, and two upper and lower first hooks 13 being welded to the other waist plate, a U-shaped space being formed between the first hook 13 and the waist plate, and the opening of the first hook 13 facing the side;

[0032] The second splint assembly 2 has the same structure as the first splint assembly 1 and is symmetrically arranged. The second hook 21 in the second splint assembly 2 is opposite to the opening of the first hook 13, the second hanging ring 22 is at the same height as the first hanging ring 12, and the second splint 23 and the first splint 11 are provided with multiple through holes 5 on the waist plate opposite to each other. Multiple long bolts 3 pass through the corresponding through holes 5 and cooperate with nuts 4 to connect the two sets of splint assemblies together.

[0033] The first clamping plate 11 and the second clamping plate 23 are both equilateral angle steels, and are both galvanized angle steels.

[0034] The first lifting ring 12 and the first clamping plate 11 , and the second lifting ring 11 and the second clamping plate 23 are connected by welding or bolts.

[0035] The first lifting ring 12 and the second lifting ring 22 are flat steel blocks with lifting ring holes 14, or are round steel bent into rings, or are U-shaped rings.

[0036] The first hook 13 and the second hook 21 are angle steels or bent flat steels.

[0037] The number of the long bolts 3 is 2, and the long bolts 3 are galvanized bolts.

[0038] The through hole 5 is a vertical long hole.

[0039] A spring washer is provided between the nut 4 and the waist plate. The spring washer can prevent loosening, and a double nut can also be used to prevent loosening.

[0040] The long bolt 3 is a bolt of M16-M30.

[0041] like Figure 4 As shown, after the first hook 13 and the second hook 21 in the present invention hook the wing plate of the H-shaped steel column 6, the two clamping plates are fastened with two long bolts 3, so that the present invention can be firmly fixed on the outside of the H-shaped steel column 6 of the sound barrier, and then the first hanging ring 12 and the second hanging ring 22 are used to hang a pulley or a safety rope to achieve related construction tasks on the outside of the sound barrier.

[0042] In specific operations, the present invention can be processed and produced according to the length of the bridge and the requirements of the construction process, and one can be set up at each location where it needs to be fixed. For most layered sound barriers, the length of the two plywood and the welding position of the two hooks on the corresponding plywood can be selected according to the distance between each layer. The gap between the two layers can be used to make it easier for the hooks to clamp the H-shaped steel column 6. Then, according to the model of the H-shaped steel column 6 of the sound barrier, a long bolt 3 of appropriate length is selected, and with the nut 4, the present invention is fixed to the H-shaped steel column 6 of the sound barrier. The through holes 5 on the two plywood are set as vertical long holes, and the installation height of the present invention can be adjusted within a certain range.

[0043] The use of this new type of equipment reduces the difficulty of constructing the outer side of the railway bridge sound barrier, making the working environment safer. It can significantly reduce construction costs and improve construction efficiency, especially for the renovation of existing railways in operation. The labor cost-benefit analysis of replacing cables in a cable trough on a 500-meter-long bridge is as follows:

[0044] 1. Use traditional construction methods: Cable replacement on the bridge needs to be carried out within the railway skylight points, and each skylight can only be operated for 3 hours, resulting in a large number of idle workers. The workers have no reliable stress points outside the sound barrier, which poses a safety hazard of falling from height. The work efficiency is low. It takes 4-5 skylights to complete the cable replacement on the entire bridge. If 2 skylights are completed per week, it will take about half a month and about 300 workers.

[0045] 2. The construction method of the present invention can realize continuous operation outside the skylight point. It takes one skylight time to complete the installation of the present invention and the safety rope, and then carry out continuous construction outside the skylight point. The same construction task can be completed in 3-4 days, and only 80 workers are needed.

[0046] Replacing the cables on a 500-meter bridge can save manpower: 300-80=220 manpower.

[0047] It can be seen from the above examples that the use of the present invention improves the working environment, significantly increases the construction efficiency, and saves construction costs.

[0048] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
