For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0028] Reference Figures 1-4 An embodiment of the present application is a grouting operation platform which is convenient to disassemble and move. The platform can be applied to grouting construction inside a tunnel, can adapt to the arc structure of the tunnel, provides a stable and safe working environment, and has the functions of convenient disassembly and movement, thereby improving construction efficiency.
[0029] The grouting operation platform of the present application mainly comprises a workbench 1, a limiting device 3, a mounting structure 4, a support structure, a lifting device 5 and a moving wheel 2.
[0030] The working frame 1 is the main structure of the whole working platform, which bears the main load-bearing function and provides the construction operation space. Its main components are as follows:
[0031] The frame body 11 is welded by high-strength alloy steel to form a rectangular frame structure to ensure the overall stability. The frame body can be composed of strip steel or steel pipe. When using strip steel, the frame body 11 can be composed by welding or bolt connection. When using steel pipe, the frame body 11 can be composed by steel pipe connector.
[0032] The support structure bottom support assembly 12 and the side support assembly 13 are installed in the frame body 11 to further enhance the carrying capacity.
[0033] The bottom support assembly 12 is composed of several tripods 121. Each tripod 121 is designed with reinforcing ribs. The tripods 121 are arranged at the bottom of the whole working platform, which can effectively support the whole working platform by using the stability of the tripods 121 to ensure the stability of the workers during work.
[0034] The connecting column 122 penetrates the tips of the plurality of tripods 121. In this way, the connecting column 122 connects all the tripods 121 together, so that all the tripods 121 form a whole, which can provide more stable support performance for the whole working platform.
[0035] For the side support assembly 13, it includes a cross 131 and a cross 132. The cross 131 is arranged on the four sides of the frame body 11, which is a regular arrangement of the working frame 1, used to enhance the lateral stability and prevent the platform from shaking. The cross 132 is arranged on the front and back sides of the frame body 11. Compared with only arranging one cross 131, it can increase the ability of the working platform to resist the tilting force, for example, the worker walks on the edge of the platform, which applies a tilting force to the whole frame body 11.
[0036] For the moving wheel 2 in the device, high-load universal wheels are used, which have double locking function to ensure the fixation of the platform in the construction position. At the same time, in order to facilitate the stable movement of the whole working frame 1 in the tunnel, the workers also lay tracks in the tunnel, and the moving wheel 2 will run on the tracks.
[0037] There are two kinds of tunnels in the present application, one is a flat ground arc top tunnel, and the other is a circular tunnel. When the present application is used in the flat ground arc top tunnel, only the working frame 1 combined with the guide rail on the flat ground is needed. For the circular tunnel, in order to increase the stability of the working frame 1, the device adds a limiting device 3 to assist the stability of the working frame 1.
[0038] The limiting device 3 is mainly used for fixing the working platform inside the tunnel, ensuring that it is firmly attached to the tunnel wall and does not displace or tilt due to external forces. Its components include mounting strips 31, which are fixed on both sides of the working frame 1 to provide a basic mounting position for the limiting device 3; mounting arms 32, which are connected to the mounting strips 31 and used to support the limiting mechanism; and air cylinders 33, which are provided on the mounting arms 32 as driving elements to control the movement of the arc plates 35 through the extension and retraction of the pistons.
[0039] When the piston rod of the air cylinder is extended, it pushes the arc plate 35 against the tunnel wall; when the piston rod is retracted, the limiting is released, making it easier to move the platform.
[0040] The connecting rod 34 in this application is connected to the piston end of the air cylinder 33 to transmit the pushing or pulling force of the air cylinder.
[0041] The arc plate 35 is provided at the end of the connecting rod 34 and mainly contacts the inner wall of the tunnel; the arc plate 35 is made of high-strength wear-resistant material, and the curvature of the arc plate 35 can be set according to tunnels of different diameters to improve the stability of the limiting.
[0042] In order to enable the arc plate 35 to stably receive the force from the air cylinder, an arc plate adjusting device is added, which includes a limiting hole provided on the mounting arm 32 and a limiting column 36 slidingly arranged in the limiting hole: the limiting column 36 can slide in the direction of the piston push of the air cylinder 33 to adjust the limiting position of the arc plate 35 and stably press against the inner wall of the tunnel.
[0043] Since the device is applied in different tunnels, the limiting device 3 is an optional structure, so in order to facilitate the disassembly and assembly of the limiting device 3, the device also provides a mounting structure 4.
[0044] The mounting structure 4 enables the limiting device 3 to be firmly mounted on the working frame 1 while ensuring easy disassembly and assembly. Its main components include a channel steel 41; the channel steel 41 is composed of a web and flanges; the web is fixedly connected to the mounting strips 31 and the mounting arms 32 and is fixed to the working frame 1 through a bolt assembly 42.
[0045] The working frame 1 is provided with threaded holes, the flanges of the channel steel 41 are provided with mounting holes corresponding in number to the threaded holes, the bolt assembly 42 includes a T-shaped bolt and a nut, the T-shaped bolt penetrates the mounting hole and is threadedly connected to the threaded hole, and the nut is threadedly connected to the other end of the T-shaped bolt. When disassembling, only the nut needs to be turned and the bolt can be removed.
[0046] For tunnels with flat arc roofs, since the heights of the arc roofs are not uniform, in order to cope with higher arc roof tunnels, the device also provides a lifting device 5 on the working frame 1.
[0047] The lifting device 5 is used for adjusting the height of the working platform to adapt to different construction requirements, so as to ensure that the grouting operation can be carried out at a proper height. The components thereof include a hydraulic cylinder 51 fixed on the upper end face of the frame body 11, and a lifting platform 52 arranged at the piston end of the hydraulic cylinder 51; and the lifting platform 52 is used for standing of the construction personnel and placing of construction tools.
[0048] At this time, the height of the lifting platform 52 can be adjusted, so that the staff can reach higher space and complete the grouting operation.
[0049] In order to enable the lifting platform to be stably lifted, vertical rods 53 are arranged at four corners of the lifting platform 52 and are inserted into vertical holes in the upper end of the frame body 11, so as to ensure that the platform does not shake or tilt during lifting.
[0050] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
