Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The first embodiment of this application is as follows:

[0027] Please see Figures 1 to 3 A cantilever construction platform for a cable-stayed bridge steel truss girder is used in the cantilever construction of a cable-stayed bridge steel truss girder. The platform includes a support frame 101, one side of which is provided with a notch for workers and machinery to enter and exit. A fixing component is provided at the notch, which includes a fixing shaft 102, a fixing plate 103, a baffle 104, and a rotating shaft 105.

[0028] The fixed shaft 102 is slidably connected to the support frame 101 and is located inside the support frame 101. The support frame 101 has an opening for accommodating the fixed shaft 102. The fixed plate 103 is fixedly connected to the fixed shaft 102 and is located at the top of the support frame 101. The baffle 104 is fixedly connected to the fixed plate 103 and is located at the bottom of the fixed plate 103. The rotating shaft 105 is fixedly connected to the fixed plate 103 and passes through the support frame 101. The support frame 101 has an opening for accommodating the rotating shaft 105. Both the rotating shaft 105 and the fixed shaft 102 extend into the support frame 101. In the opening at the top, the length of the rotating shaft 105 exceeds the length of the fixed shaft 102. The rotating shaft 105 provides a limiting and rotation function for the fixed component. The baffle 104 is used to protect the workers inside the support frame 101. The fixed plate 103 provides support for the rotating shaft 105 and the fixed shaft 102. When the workers need to go up or down the construction platform, the fixed plate 103 is lifted upwards, which at the same time drives the fixed shaft 102 to be pulled out from the inside of the support frame 101. Then the fixed plate 103 is rotated along the rotating shaft 105, so that the workers can easily enter and exit from the inside of the support frame 101.

[0029] Support components are connected to the support frame 101. The support components include support columns 106, inclined rails 107, and bases 108. There are multiple support columns 106, each fixedly connected to the support frame 101 and located at the bottom of the support frame 101. The bases 108 are fixedly connected to the support columns 106 and located at the bottom of the support columns 106. There are multiple inclined rails 107, each fixedly connected to the support frame 101 and the bases 108 at both ends. The support columns 106 provide support for the bases 108 and the support frame 101. The bases 108 protect workers from falling from below the support frame 101. The inclined rails 107 protect workers from falling through the gap between the support frame 101 and the bases 108.

[0030] A buffer assembly is connected to the support frame 101. The buffer assembly includes a buffer plate 109, a buffer spring 110, and a contact plate 111. The buffer plate 109 is fixedly connected to the support frame 101 and is located on both sides of the support frame 101. There are multiple buffer springs 110, which are fixedly connected to the buffer plate 109 and are located on the side of the buffer plate 109 away from the support frame 101. There are multiple contact plates 111, which are fixedly connected to the buffer spring 110 and are located at the end of the buffer spring 110 away from the buffer plate 109. The buffer plate 109 is used to install the buffer assembly on the outside of the support frame 101. The buffer spring 110 provides elasticity to the contact plate 111, so that when the contact plate 111 comes into contact with the wall or bridge, the impact force on the construction platform is reduced, making the construction platform safer.

[0031] A sunshade assembly is connected to the support frame 101. The sunshade assembly includes support rods 112, adjusting rods 113, fixing rods 114, and a sunshade panel 115. There are four support rods 112, all of which are fixedly connected to the support frame 101 and are located around the top of the support frame 101. There are four adjusting rods 113, which are slidably connected to the four support rods 112. The bottom of the adjusting rods 113 is located inside the support rods 112. There are four fixing rods 114, which are detachably connected to the support rods 112 and pass through the support rods 112 and the adjusting rods 113. The sunshade panel 115 is fixedly connected to the adjusting rods 113 and is located at the top of the adjusting rods 113. The support rods 112 provide support for the sunshade assembly. By adjusting the height of the adjusting rods 113 within the support rods 112, the height of the sunshade panel 115 can be adjusted. The adjusting rods 113 are positioned on the support rods 112 by the fixing rods 114.

[0032] In the cantilever construction of the steel truss girder of the cable-stayed bridge, the support frame 101 provides support for the fixed components, the rotating shaft 105 provides limiting and rotation functions for the fixed components, the baffle 104 is used to protect the workers inside the support frame 101, and the fixed plate 103 provides support for the rotating shaft 105 and the fixed shaft 102. When the workers need to go up or down the construction platform, the fixed plate 103 is lifted upwards, which at the same time drives the fixed shaft 102 to be pulled out from the inside of the support frame 101. Then the fixed plate 103 is rotated along the rotating shaft 105, and the baffle 104 is opened to facilitate the entry and exit of workers and machinery from the inside of the support frame 101.

[0033] Moving the fixed plate 103 upwards further can separate the fixed shaft 102 from the support frame 101, allowing the fixed plate 103 and baffle 104 to be removed, thus preventing the fixed plate 103 and baffle 104 from obstructing the equipment from entering the support frame 101.

[0034] The second embodiment of this application is as follows:

[0035] Based on the first embodiment, please refer to Figure 4 ,in, Figure 4 This is a structural schematic diagram of the fixing buckle and support assembly of the second embodiment of this utility model.

[0036] The cantilever construction platform for the cable-stayed bridge steel truss girder in this embodiment also includes a fixing buckle 201.

[0037] In this specific embodiment, there are multiple fixing buckles 201. The multiple fixing buckles 201 are fixedly connected to the base 108 and the support frame 101 respectively, and are located on the outside of the base 108 and the support frame 101 respectively. Each fixing buckle 201 has a fixing hole 202 on its surface. The fixing buckle 201 is used to connect with the external steel wire rope. The steel wire rope can pass through the fixing hole 202 on the surface of the multiple fixing buckles 201. Through the external lifting device, the purpose of conveniently lifting and lowering the construction platform is achieved.

[0038] Using the cantilever construction platform for a cable-stayed bridge steel truss in this embodiment, the wire rope can pass through the fixing holes 202 provided on the surface of multiple fixing buckles 201. Through the external lifting device, the construction platform can be easily lifted and lowered, thus achieving the purpose of assisting in the cantilever construction of the cable-stayed bridge steel truss.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
