[0022] Next, the embodiments of the technical solution of the present utility model will be described in detail in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a traveling guiding device for a shield tunnel operation vehicle, including a guide rail 100 and a connection and fixing member 200. Specifically, the guide rail 100 is arranged along the extension direction of the shield tunnel. There are two guide rails 100, and the two guide rails 100 are arranged opposite to each other left and right. A guide groove is opened at the top of the guide rail 100, and the wheels 2 of the shield tunnel operation vehicle can slide along the guide groove. Each guide rail 100 is suspended on the shield tunnel segment 1 through a connection and fixing member 200.

[0024] During installation, first install the connection and fixing member 200 on one side of the shield tunnel segment 1. After completing the installation of all connection and fixing members 200 on one side, place the guide rail 100 on the connection and fixing member 200 and fix it. Subsequently, in the same way, install the connection and fixing member 200 and the guide rail 100 on the other side. When the operation vehicle is working, place the left and right wheels of the operation vehicle in the guide grooves on the left and right sides respectively and move forward along the guide grooves.

[0025] By using the above-mentioned traveling guiding device for a shield tunnel operation vehicle, through the guidance of the guide groove, the wheels 2 can stably travel on the slope with an arc-shaped cross-section in the tunnel, avoiding the occurrence of wheel 2 slipping and sudden changes and disorders in the driving trajectory. At the same time, since the operation vehicle travels stably, the probability of deformation of the operation vehicle frame can be further reduced, thereby extending the service life of the operation vehicle. In addition, the entire device has a simple structure and is convenient to install.

[0026] It should be noted that in specific implementation, the left and right span of the guide rail 100 should be determined according to the width of the operation vehicle, and the height of the guide rail 100 also needs to be determined according to the working height. Of course, an operation vehicle with a matching size can also be made according to the span and height of the pre-installed guide rail 100. In addition, there can be multiple connection and fixing members 200, and the multiple connection and fixing members 200 are arranged at equal intervals along the extension direction of the guide rail 100. At the same time, the number of guide rails 100 can be an even number such as 4, 6, 8, etc., and the specific number can be determined according to the driving distance of the operation vehicle or the length of the tunnel.

[0027] In addition, during specific implementation, the guiding rail 100 can be selected as the commonly used No. 10 channel steel in the prior art and processed according to the required length. Selecting the ready-made channel steel can save processing costs and processing time.

[0028] In this embodiment, the connecting and fixing member 200 includes a connecting bolt 210, a hanging plate 220, and a baffle 230. The baffle 230 is fixed at the tail end of the hanging plate 220 and forms an installation cavity with an upward opening with the baffle 230. The guiding rail 100 is arranged in the installation cavity. The connecting bolt 210 is installed on the shield tunnel segment 1. A bolt hole is provided at the tail end of the baffle 230. The baffle 230 is connected to the connecting bolt 210 through the bolt hole.

[0029] In this way, during installation, after all the connecting and fixing members 200 are installed, the guiding rail 100 is directly placed in the installation cavity, and the baffle 230 plays a supporting and blocking role for the guiding rail 100. This installation method can achieve the fast and simple installation of the guiding rail 100. Of course, during specific implementation, to prevent the guiding rail 100 from sliding, the guiding rail 100 can also be threadedly connected or clamped with the hanging plate 220 for limiting. In addition, during specific implementation, the hanging plate 220 and the baffle 230 can be integrally formed by a steel plate. If it is bent, the processing steps can be reduced.

[0030] In this embodiment, the included angle between the hanging plate 220 and the baffle 230 can be 90°. The 90-degree included angle can make the inner side surface of the baffle 230 all contact the side wall of the guiding rail 100, thereby forming a stable support for the guiding rail 100.

[0031] In addition, the hanging plate 220 can be arranged to be inclined downward relative to the vertical direction, the head end of the hanging plate 220 is bent into a horizontal state, and the bolt hole is opened on the head end of the hanging plate 220. By arranging the hanging plate 220 to be inclined downward, the arc-shaped inner wall of the tunnel can be adapted, and the tail end of the hanging plate 220 can be placed on the arc-shaped inner wall of the tunnel, forming a certain support for the hanging plate 220.

[0032] By adopting the above-mentioned running guiding device for the shield tunnel working vehicle, through the guiding of the guiding groove, the wheels 2 can walk stably on the slope with an arc-shaped cross-section in the tunnel, avoiding the occurrence of side slipping of the wheels 2 and the sudden change and disorder of the driving track. At the same time, since the working vehicle travels stably, the probability of deformation of the working vehicle frame can be further reduced, thereby extending the service life of the working vehicle. In addition, the whole device has a simple structure and is convenient to install.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
