However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0024] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figures 1-6 As shown, a protective device for a construction pit of a highway bridge includes: a plurality of support plates 6 arranged around the pit 1; a protective plate 8, which is inserted through the middle of the support plate 6, and a second guide sleeve 22 is sleeved on the outside of the protective plate 8, and the second guide sleeve 22 is fixedly connected to the bottom surface of the support plate 6; a first cone 26, and a plurality of first cones 26 are fixedly provided at the bottom of the protective plate 8; a buffer mechanism, which is installed on the top of the support plate 6; a fixed rod 3, the top of the fixed rod 3 is fixedly connected to the bottom surface of the support plate 6; and a second cone 14, the second cone 14 is fixedly connected to the bottom of the fixed rod 3.

[0027] The buffering mechanism comprises: a base 17, which is fixed on the top surface of the support plate 6 away from the foundation pit 1; a rotating drum 16, which is fixed on the top surface of the base 17; a rotating shaft 18, one end of which is rotatably connected in the rotating drum 16; a buffering baffle 5, which is fixedly connected with the rotating shaft 18 at the bottom; a first spring 4, the upper end of which is fixedly connected with the buffering baffle 5, and the lower end of which is fixedly connected with the support plate 6; a first gear 15, which is fixedly sleeved on the other end of the rotating shaft 18; a first guide sleeve 23, which is fixedly penetrated in the bottom of the protection plate 8 and located above the support plate 6; a driving plate 9, which is slidingly inserted in the first guide sleeve 23, and the top surface of which is fixedly provided with a first rack 24 engaged with the first gear 15; a vertical plate 21, which is arranged on the front and back sides of the driving plate 9 and fixedly connected with the support plate 6; a second rotating shaft 19, which is rotatably connected with the two vertical plates 21 at the front and back ends; a second gear 20, which is fixedly sleeved on the second rotating shaft 19; a second rack 25, which is fixedly provided on the top surface of the driving plate 9; a plurality of tooth grooves 7, which are formed in the protection plate 8 near the second gear 20 along the height direction of the protection plate 8; a first connecting plate 10, which is fixedly connected with one end of the driving plate 9 near the foundation pit 1; a second connecting plate 12, which is fixedly connected with one end of the support plate 6 near the foundation pit 1; and a second spring 11, which connects the first connecting plate 10 and the second connecting plate 12.

[0028] Working principle: the bottom of the protection plate 8 and the fixed insertion rod 3 are inserted into the soil, so that the support plate 6 is attached to the slope surface 2. When a person or equipment falls and slides along the slope surface 2 by accident, it first hits the buffering baffle 5 to drive the buffering baffle 5 to rotate along the rotating drum 16, and at the same time, the buffering baffle 5 can effectively play a buffering role under the elastic force of the first spring 4. When the buffering baffle 5 rotates, it drives the first gear 15 to rotate synchronously through the rotating shaft 18. The first gear 15 drives the driving plate 9 to move through the first rack 24. The driving plate 9 drives the second gear 20 to rotate through the second rack 25. The second gear 20 drives the protection plate 8 to move downward through the tooth groove 7, so that the protection plate 8 can be inserted deeper into the soil. The impact force when a person or equipment hits is converted into driving force to drive the protection plate 8 to move downward, so that the device can be inserted deeper into the soil when it is hit, effectively preventing the device from being knocked down and preventing people or equipment from falling into the foundation pit 1.

[0029] Example 2

[0030] As Figure 3As shown, in other parts are same with example 1, the difference between this example and example 1 is that the second cone 14 is provided with a plurality of barbs 13. By setting the barbs 13, the resistance of the second cone 14 in the soil can be increased when moving up, thereby effectively preventing the fixed insertion rod 3 from being pulled out.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
