[0021] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0022] Example

[0023] like Figures 1-4 As shown in the figure, an embodiment of this utility model discloses a single-track tunnel mobile construction device, which mainly includes a track bar 1, a base frame 2, an inclined support frame 3, and a working platform 4. The track bar 1 serves as the running track of the construction device, on which the base frame 2 is installed. The base frame 2 is connected to the track bar 1 through a guide sliding assembly to ensure that the base frame 2 can move smoothly on the track bar 1. The guide sliding assembly specifically consists of roller 5 and roller 7. Roller 5 rolls on the track bar 1, providing the main forward propulsion; roller 7 rolls on the side of the track bar 1 and is connected to the base frame 2 through an L-shaped connecting rod 6 to increase the stability of movement. In addition, an overlapping plate 8 is fixedly connected between the two L-shaped connecting rods 6 for connecting a limiting mechanism.

[0024] Furthermore, a limiting mechanism is designed in detail and installed between the first overlapping plate 8 and the track 1. Specifically, the n-shaped frame 9 is fixedly connected to the surface of the first overlapping plate 8, and a limiting rod 15 is inserted at its top. The end of the limiting rod 15 passes through the first overlapping plate 8 and can be inserted into the limiting insertion hole 16 on the side of the track 1 when needed, thereby fixing the bottom fixing frame 2 in a specific position. To ensure that the limiting rod 15 can be smoothly inserted and removed, a reset structure is also connected between the n-shaped frame 9 and the limiting rod 15. The reset structure includes a strip-shaped through groove 10, a fixing rod 11, a spring 12, a sliding sleeve block 13, and the second overlapping plate 14. The spring 12 is sleeved on the fixing rod 11, and its two ends are respectively connected to the end wall of the strip-shaped through groove 10 and the sliding sleeve block 13. The sliding sleeve 13 slides within the strip groove 10 and is connected to the limiting rod 15 via the overlapping plate 14, thereby achieving automatic reset of the limiting rod 15 under the action of the spring 12.

[0025] Further, the core of the reset structure is to use the elastic force of the spring 12 to achieve the automatic reset of the limiting plug 15. Specifically, when the limiting plug 15 is pulled out of the limiting plug hole 16 by an external force, the spring 12 is compressed and stores energy. Once the external force disappears, the spring 12 releases the energy, pushes the sliding sleeve block 13 to slide in the strip-shaped through slot 10, and in turn drives the reset of the lapping plate two 14 and the limiting plug 15. This design not only simplifies the operation process, but also improves the safety and reliability of the construction device.

[0026] Further, the roller three 17 and the guardrail 18 are added on the workbench plate 4. The roller three 17 is installed at one end of the workbench plate 4, which is used to roll on the tunnel wall, thereby reducing the frictional resistance between the workbench plate 4 and the tunnel wall, and making the construction device move more smoothly in the tunnel. The guardrail 18 is fixedly connected to the upper end surface of the workbench plate 4, which provides necessary safety protection for the construction personnel.

[0027] Further, in order to ensure that the limiting plug 15 can be accurately and stably inserted into the limiting plug hole 16, the design outer diameter of the limiting plug 15 and the opening inner diameter of the limiting plug hole 16 are strictly designed in this embodiment. Specifically, the opening inner diameter of the limiting plug hole 16 is slightly larger than the design outer diameter of the limiting plug 15, so as to ensure that there is no excessive resistance or jamming phenomenon during the insertion process. At the same time, this design also ensures that the limiting plug 15 can tightly fit the inner wall of the limiting plug hole 16 after insertion, realizing effective limiting and fixing.

[0028] Further, in the reset structure, the connection mode of the spring 12 is crucial to its reset effect. This embodiment adopts a connection mode that one end is fixedly connected to the end wall of the strip-shaped through slot 10, and the other end is fixedly connected to one end surface of the sliding sleeve block 13. This connection mode ensures that the spring 12 can maintain a stable force line direction when being compressed or stretched, thereby realizing effective reset of the limiting plug 15. At the same time, it is also convenient to replace and maintain the spring 12.

[0029] It should be understood that all the details provided above are merely exemplary and do not limit the present specification. Various modifications, improvements, and alterations can be made to the present specification by those skilled in the art.
