[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figure 1-8As shown, a protective device for construction site openings includes two support piles 1. The lower ends of the two support piles 1 are equipped with insertion components. Each insertion component includes conical insertion blocks 7 fixedly connected to the lower ends of the two support piles 1. The conical insertion blocks 7 are inserted into the ground at the opening. Two foot pedals 8 are fixedly connected to the annular sidewalls near the upper ends of the two conical insertion blocks 7. The foot pedals 8 are used to manually step on or hammer the conical insertion blocks 7 into the ground at the opening. The upper ends of both support piles 1 are provided with grooves 2, and lifting piles 3 are movably inserted into both grooves 2. The opposing inner walls of the two grooves 2... Each of the two limit grooves 9 is provided with a limiting groove 9. Each of the two limiting grooves 9 is slidably connected with a matching limiting slider 10. The ends of the two limiting sliders 10 away from the limiting grooves 9 are respectively fixedly connected to the side walls of the two lifting piles 3 near the lower end. The top surfaces of the two limiting grooves 9 are connected to the upper end of the support pile 1. The bottom of the two limiting grooves 9 are on the same horizontal plane as the bottom of the groove 2. When the limiting slider 10 moves in the limiting groove 9, it facilitates the vertical lifting of the lifting pile 3 in the groove 2, while limiting the range of movement of the lifting pile 3, so that the lifting pile 3 can smoothly move vertically along the groove 2.

[0033] Positioning components are provided on the inner walls of the two grooves 2. The positioning components are associated with the lifting piles 3. The positioning components include several through holes 11 respectively provided on the inner walls of the two grooves 2. The several through holes 11 on the same side are distributed at equal intervals. A positioning bolt 12 is inserted through one of the through holes 11. The positioning bolt 12 is installed through the through hole 11 and threadedly connected to the threaded groove 13, effectively fixing the lifting piles 3 in the grooves 2. Threaded grooves 13 are provided on the opposite side walls of the two lifting piles 3 near the lower end. The two positioning bolts 12 are threadedly connected to the two threaded grooves 13 respectively.

[0034] Two lifting piles 3 are fixedly connected to the upper ends of fixed plates 4. Support plates 5 are provided above the two fixed plates 4. A buffer mechanism is provided between the fixed plates 4 and the support plates 5. The buffer mechanism includes limiting rods 14 fixedly connected to the upper ends of the fixed plates 4 near the four corners and several spring buffer rods 15 fixedly connected to the upper ends of the fixed plates 4. The several spring buffer rods 15 are evenly distributed. The upper ends of the several limiting rods 14 are vertically inserted through the support plates 5. Limit blocks 16 are fixedly connected to the upper ends of the several limiting rods 14. The upper ends of the several spring buffer rods 15 are fixedly connected to the lower ends of the support plates 5. First shock-absorbing springs 17 are sleeved on the several limiting rods 14. The first shock-absorbing springs 17, together with the several spring buffer rods 15, buffer and protect the protective plate 24 between the support platforms 6, so as to prevent the lifting piles 3 from deforming after the protective plate 24 is subjected to force, and improve the stability of the protective device. The several first shock-absorbing springs 17 are all set between the fixed plates 4 and the support plates 5.

[0035] The spring buffer rod 15 includes a telescopic rod 18 fixedly connected between the fixed plate 4 and the support plate 5. A second shock-absorbing spring 19 is fixedly sleeved on the telescopic rod 18. The elastic properties of the second shock-absorbing spring 19, in conjunction with the telescopic rod 18, enhance the buffering effect on the support plate 5 and the support platform 6. It also works with the first shock-absorbing spring 17 to provide buffering protection for the several protective plates 24 between the two support platforms 6. The upper ends of the two support plates 5 are provided with mounting components. The mounting components are provided with several support platforms 6. The mounting components include several rectangular protrusions located at the upper end of the center position of the support plate 5. The support plate 6 is mounted on a rectangular protrusion 20, which is evenly spaced. Several U-shaped brackets 21 are snapped onto the rectangular protrusions 20. Two double-headed bolts 22 are horizontally inserted between the rectangular protrusions 20 and the U-shaped brackets 21. Nuts 23 are threaded onto the double-headed bolts 22. The double-headed bolts 22 are inserted through the rectangular protrusions 20 and the U-shaped brackets 21 and fitted with nuts 23 for fixation. This effectively fixes the support plate 6 onto the rectangular protrusions 20, facilitating installation. The rectangular protrusions 20 and the support plate 5 are integrally formed.

[0036] Several support platforms 6 are arranged in pairs facing each other. A protective mechanism is provided between two opposing support platforms 6. The protective mechanism includes several protective plates 24 disposed between the two support platforms 6. Several first positioning blocks 25 are fixedly connected to the opposite side walls of the two support platforms 6. Several first positioning blocks 25 on the same side are respectively positioned opposite several rectangular protrusions 20. Connecting blocks 26 and second positioning blocks 27 are fixedly connected to the left and right side walls of the protective plates 24 respectively. Several first positioning blocks 25 and second positioning blocks 27 are respectively positioned opposite several connecting blocks 26. Slots 28 are provided on the side walls of several first positioning blocks 25 and second positioning blocks 27 facing the connecting blocks 26. Adjacent protective plates 24 and side protective plates 24 are connected to the two support platforms 6, so that several connecting blocks 26 are respectively inserted into the slots 28 on the first positioning blocks 25 and second positioning blocks 27. At this time, the inclined end face of the wedge-shaped locking block 32 abuts against the inner wall of the slot 28. The top surface of several slots 28 Both the top and bottom are provided with bayonets 29. Each of the connecting blocks 26 has slots 30 at both ends. A pressure spring 31 is fixedly connected to the inner wall of each slot 30. A wedge-shaped locking block 32 is fixedly connected to the end of each pressure spring 31 furthest from the inner wall of the slot 30. The connecting blocks 26 are respectively inserted into slots 28. The wedge-shaped locking block 32 moves within the slot 30 and compresses the pressure spring 31 until it is fully inserted into the slot 28, compressing the pressure spring 31. The elastic reset causes the wedge-shaped locking block 32 to pass through the bayonet 29, effectively locking and fixing the connecting block 26 and the wedge-shaped locking block 32 in the slot 28, which facilitates the quick splicing and fixing of several protective plates 24. When one of the protective plates 24 is damaged and needs to be replaced, simply press the two wedge-shaped locking blocks 32 to separate from the bayonet 29, and pull the connecting block 26 to separate from the slot 28, which makes it easy to replace the protective plate 24. The two wedge-shaped locking blocks 32 on the same side pass through two opposite bayonet 29 respectively.

[0037] In use, the conical insert 7 at the lower end of the support pile 1 is inserted into the ground at the opening where protection is needed. The conical insert 7 is then manually stepped on or hammered into the ground using a foot pedal 8, facilitating rapid fixation of the support pile 1. Next, adjacent protective plates 24 are aligned, as are the side protective plates 24 with the two support platforms 6, allowing several connecting blocks 26 to be inserted into the slots 28 on the first positioning block 25 and the second positioning block 27. At this point, the inclined end face of the wedge-shaped locking block 32 abuts against the inner wall of the slot 28, causing the wedge-shaped locking block 32 to move within the slot 30 and compress the pressure spring 31 until it is fully inserted into the slot 28. The compressed pressure spring 31 then elastically returns to its original position, causing the wedge-shaped locking block 32 to pass through the locking opening 29, effectively securing the connecting blocks 26 and the wedge-shaped locking block 32 within the slot 28. This facilitates the rapid assembly and fixation of several protective plates 24. When one of the protective plates 24 is damaged and needs to be replaced, simply press the two wedge-shaped blocks 32 to separate from the slot 29, and pull the connecting block 26 to separate from the slot 28. This makes it easy to replace the protective plate 24. When it is necessary to adjust the protection height according to the opening height, simply unscrew the positioning bolt 12 to separate from the threaded groove 13 and the through hole 11, and pull the lifting pile 3 to rise and fall vertically under the limiting action of the limiting groove 9 and the limiting slider 10. After the lifting pile 3 has moved, the positioning bolt 12 is then set through the corresponding through hole 11 and threadedly connected to the threaded groove 13 to effectively position the lifting pile 3. This makes it easy to adjust the protection height according to the opening height. When the protective plate 24 is under force, the first shock-absorbing spring 17 on several limiting rods 14, together with several spring buffer rods 15, buffers and protects the protective plate 24 between the support platform 6, preventing the lifting pile 3 from deforming after the protective plate 24 is under force, and improving the stability of the protective device.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
