[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Examples, such as Figures 1-4 As shown, a temporary construction support device for highway engineering includes a base plate 1 and a support plate 2 rotatably connected to the base plate 1. A support rod 7 and a sliding rod 8 are provided between the base plate 1 and the support plate 2. A limit device is provided between the support rod 7 and the sliding rod 8. By providing an elastic device between the sliding rod 8 and the support rod 7, when the support plate 2 rotates to be perpendicular to the base plate 1, the sliding rod 8 slides rapidly with the support rod 7 due to the action of the elastic device, thereby quickly supporting the support plate 2. When the support plate 2 is perpendicular to the base plate 1, the operator operates the limit device to limit the position of the sliding rod 8, preventing it from continuing to slide with the support rod 7 due to the elastic force of the elastic device. Thus, the support plate 2 can quickly become perpendicular to the base plate 1, and the support plate 2 has good support capacity.

[0026] The limiting device includes: a bolt 18 threadedly connected to the outside of the support rod 7; a connecting post 15 connected to the bolt 18 via a plug rod 19; a first locking block 16 and a second locking block 17 fixedly installed at one end of the connecting post 15 and the bolt 18, respectively; the first locking block 16 and the second locking block 17 being slidably connected; and a connecting spring 20 rotating between the connecting post 15 and the bolt 18. The operator pre-threads the bolt 18 to the support rod 7 to ensure a stable connection between the limiting device and the support rod 7. When the sliding rod 8 needs to slide, the operator pulls and rotates the connecting post 15, thereby fixing the bolt 18 to the support rod 7. The first locking block 16 on the connecting column 15 moves together, and then the first locking block 16 abuts against the second locking block 17. At this time, the connecting spring 20 is in a stretched state, and because one end of the plug rod 19 is rotatably connected to the connecting column 15, when the connecting column 15 moves, it drives the plug rod 19 to move together. At this time, the plug rod 19 is located inside the bolt 18. When the sliding rod 8 does not need to slide, the operator pulls and rotates the connecting column 15, so that the first locking block 16 and the second locking block 17 are slidably connected. At this time, one end of the plug rod 19 is located outside the bolt 18 and passes through the sliding rod 8, thereby limiting the position of the sliding rod 8.

[0027] Furthermore, such as Figure 3As shown, the connecting column 15 is rotatably connected with the plug-in rod 19, the plug-in rod 19 penetrates the bolt 18 and is slidably connected with the bolt 18, the upper end of the supporting rod 7 is provided with a threaded hole 9, the bolt 18 is threadedly connected with the threaded hole 9, the upper and lower ends of one side of the sliding rod 8 are both provided with sliding holes 10, the plug-in rod 19 is slidably connected with the sliding holes 10, the threaded hole 9 is arranged on the supporting rod 7, so that the bolt 18 can be threadedly connected with the supporting rod 7 through the threaded hole 9, and two sliding holes 10 are arranged on the sliding rod 8, when the plug-in rod 19 is slidably connected with the sliding hole 10 close to the supporting rod 7, the supporting plate 2 and the bottom plate 1 are in a vertical state, and the supporting effect of the supporting plate 2 is best, when the plug-in rod 19 is slidably connected with the sliding hole 10 away from the supporting rod 7, the larger part of the sliding rod 8 is located inside the supporting rod 7.

[0030] Conversely, when the supporting plate 2 needs to be opened, the worker twists the baffle 22, so that one side of the plane of the baffle 22 rotates above the supporting plate 2, at this time, the supporting plate 2 no longer limits the baffle 22, when the worker lifts the supporting plate 2, the sliding block 6 will slide a short distance, driving the supporting rod 7 and the sliding rod 8 to slightly lift, so that the worker can pull and rotate the connecting column 15, so that the limiting device does not limit the supporting rod 7 and the sliding rod 8.
