[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1As shown, Example 1 of the utility model provides a finished protection device for the corners of a tunnel floor, comprising an angle steel 1, a positioning plate 2, a top support rod group and a connecting plate 3, wherein the angle steel 1 is used to be placed on the edge of the floor, the positioning plate 2 is configured as an angle plate, and the positioning plate 2 and the top support rod group are each provided with one at both ends of the connecting plate 3, the top support rod group comprises a lead screw 4 and a threaded sleeve 5, the threaded sleeve 5 is threadedly sleeved on the outside of the lead screw 4, and the positioning plate 2 is connected to the outer end of the top support rod group.

[0019] During the operation, first place the angle steel 1 on the edge of the bottom plate, and adjust the length between the two positioning plates 2 by using the screw 4 and the threaded sleeve 5, so that the horizontal parts of the two positioning plates 2 can be placed on the top of the angle steel 1 on the bottom plate corners on both sides of the ditch, and then continue to adjust the distance between the two positioning plates 2 by using the screw 4 and the threaded sleeve 5, so that the vertical parts of the two positioning plates 2 can respectively abut against the angle steel 1, thereby fixing the angle steel 1, and then using the angle steel 1 to effectively protect the bottom plate corners.

[0020] The surface of the angle steel 1 is coated with a reflective identification layer. At this time, the reflective identification layer allows the vehicle driver to clearly observe the edge of the ditch, preventing the vehicle from rolling over the corners and falling into the ditch, thereby improving the safety of the operation.

[0021] The wire sleeves 5 are fixedly mounted on both ends of the connecting plate 3, the connecting plate 3 is configured as an angle plate, and the positioning plate 2 is fixedly connected to the outer end of the lead screw 4. By directly rotating the connecting plate 3, the two wire sleeves 5 rotate, at this time, the wire sleeves 5 drive the two lead screws 4 to move outward, and then the positioning plate 2 is used to fix the angle steel 1 on the corner of the bottom plate, thereby protecting the corner of the bottom plate.

[0022] like Figures 2 to 4 As shown, in Example 2 of the utility model, the connecting plate 3 and the wire sleeve 5 are both arranged to be a square tubular structure, the wire sleeve 5 is slidably inserted into the end of the connecting plate 3, the positioning plate 2 is fixedly mounted on the outer end of the wire sleeve 5, the inner end of the screw 4 is rotatably mounted in the connecting plate 3, and a driving component for driving the two screws 4 to rotate synchronously in the opposite direction is provided in the middle of the connecting plate 3.

[0023] Among them, the driving components include a driving bevel gear 6, a driven bevel gear 7, a driving shaft 8 and an operating rod 9. The driving bevel gear 6 and the driven bevel gear 7 are both located inside the connecting plate 3. The driving shaft 8 passes through the connecting plate 3 horizontally, and the driving shaft 8 is perpendicular to the thread sleeve 5. The driving bevel gear 6 is fixedly sleeved on the driving shaft 8. A driven bevel gear 7 is arranged at the inner end of each of the two lead screws 4, and the driven bevel gear 7 is meshed with both sides of the driving bevel gear 6. The two ends of the driving shaft 8 extend from both sides of the connecting plate 3 respectively, and at least three operating rods 9 are arranged at equal distances in the circumferential direction at the end of the connecting plate 3.

[0024] When the angle steel 1 is fixed to the corner of the base plate, the driving shaft 8 is driven to rotate by pressing the operating lever 9, and the driving shaft 8 drives the driving bevel gear 6 to rotate. The driving bevel gear 6 drives the two driven bevel gears 7 to rotate so that the two lead screws 4 rotate synchronously. At this time, the two lead screws 4 respectively cause the two thread sleeves 5 to move outward and drive the positioning plate 2 to abut against the angle steel 1, thereby fixing the angle steel 1 on the corner of the base plate to achieve the effect of protecting the corner.

[0025] In addition, in the present embodiment 2, at any moment, there is an operating rod 9 located in a state where the outer end is tilted upward. Thus, by pressing down the operating rod 9 whose outer end is tilted upward, the tunnel floor corner finished product protection device as a whole is subjected to downward pressure. At this time, the positioning plate 2 can be pressed more stably on the angle steel 1, thereby improving the fixing effect of the angle steel 1.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
