[0022] The utility model provides a combined safety device for covering the opening of a pile hole, such as Figure 1-Figure 4As shown, it includes four protective fences 1, which form a protective structure. A covering mesh 2 is horizontally installed on the inner side of the protective structure. The covering mesh 2 is a U-shaped angle steel wire mesh structure. The outer edge of the covering mesh 2 is fixed to the inner side of the protective fence 1 through a groove-type connector 4. A fluorescent plate 5 is installed on the outer wall of the protective fence 1. The protective fence 1 is composed of two upper and lower plates, the lower plate 11 is the lower plate, and the upper plate 12 is the upper plate. A slot is provided at the bottom of the upper plate 12, and a plug plate is provided on the top of the lower plate 11. The plug plate is plugged into the slot. The upper plate 12 slides vertically to adjust the height and is locked and fixed by adjusting bolts 13. The protective structure surrounded by four protective fences 1, in conjunction with the covering mesh 2 installed horizontally on the inner side, achieves comprehensive coverage and protection of the pile hole opening, effectively prevents people or objects from falling into the hole, and improves the safety of the construction site. The covering mesh 2 adopts a U-shaped angle steel wire mesh structure, which not only ensures sufficient strength and stability, but also facilitates installation and disassembly. At the same time, its outer side is firmly connected to the protective fence 1 through a groove-type connector 4, which enhances the stability of the overall structure. The protective fence 1 is designed as a combination structure of two upper and lower plates (lower plate 11 and upper plate 12). The upper plate 12 can slide vertically to adjust the height and is locked and fixed by adjusting bolts 13. This design allows the device to shorten and lengthen the height, which is convenient for height adjustment according to different needs, and it is convenient to shorten it for transportation when not in use, and lengthen it when in use. The outer wall of the protective fence 1 is installed with a fluorescent plate 5, which can play a good warning role even in an environment with insufficient light, reminding construction personnel to pay attention to the position of the hole, further enhancing safety. A warning light 6 is installed on the top of the protective fence 1. The power supply of the warning light 6 is powered by a solar panel 7. The warning light 6 can improve the warning effect. The solar panel 7 is used for solar power supply.

[0023] In this embodiment, the length of the protective fence 1 is 1500mm and the height is 1200mm. A frame is installed on the outer side of the protective fence 1. The frame is made of a square tube with a specification of 30mm*30mm*2mm. The middle of the protective fence 1 is reinforced horizontally and vertically with a 25mm*25mm*1.5mm square tube.

[0024] Specifically, the side length of the covering mesh 2 is 1440mm*1440mm, and a frame is installed on the outer side of the covering mesh 2. The frame is welded with angle steels with specifications of 30mm*30mm*3mm, and the length is 1440mm; a wire mesh is added in the middle of the covering mesh 2, and the spacing between the wires is 100mm.

[0025] Furthermore, legs are installed at the bottom of the protective fence 1 to facilitate the support and positioning of the bottom of the device.

The tubular connector 3 is also equipped with a hook pin with a diameter of 10 mm and a length of 100 mm. The tubular connector 3 is arranged on both vertical sides of a single frame of the protective fence 1, and two tubular connectors 3 are arranged on each side. The protective fences 1 are spliced ​​and assembled in pairs through the tubular connectors 3, and the hook pins in the tubular connector 3 realize the firm fixation of the protective fence 1.

[0027] Furthermore, the groove-type connector 4 is an iron sheet with a width of 35 mm and a length of 50 mm and is perpendicular to each other. Two groove-type connectors 4 are welded on each frame of the covering mesh 2, and the spacing between the groove-type connectors 4 on each frame is 1000 mm; the covering mesh 2 is erected on the upper, middle and lower horizontal square tubes of the protective fence 1 through the groove-type connectors 4 to achieve the coverage requirements of the pile hole openings in different scenarios.

[0028] Furthermore, a locking bolt 41 is installed on the outer side of the groove-shaped connector 4, a pressure plate is installed on one end of the locking bolt 41, the pressure plate abuts against the horizontal square tube of the protective fence 1, and a screwing handle is installed on the other end of the locking bolt 41.

[0029] The groove-type connector 4 is designed with mutually perpendicular iron sheets with a width of 35mm and a length of 50mm. This structure makes the connector have a certain strength and can be firmly connected to the covering mesh 2 and the protective fence 1. Two groove-type connectors 4 are welded on each frame, and the spacing is 1000mm, which ensures that the frame of the covering mesh 2 can be stably fixed on the protective fence 1. The covering mesh 2 is set on the upper, middle and lower horizontal square tubes of the protective fence 1 through the groove-type connector 4. This design allows the covering mesh 2 to flexibly adjust its position on the protective fence 1 according to the needs of different scenes, so as to better cover the pile hole opening. The outer side of the groove-type connector 4 is installed with a locking bolt 41, which cooperates with the pressure plate and the screwing handle, so that the operator can easily lock or loosen the connector, thereby quickly and safely completing the installation or removal of the covering mesh 2. The pressure plate abuts against the horizontal square tube of the protective fence 1, which increases the stability of the connection.

[0030] When the combined safety device for covering the pile hole opening of the utility model is used, firstly, four protective fences 1 are spliced ​​and assembled in pairs through the tubular connectors 3, and the hook pins in the tubular connectors 3 realize the fixing and firmness of the protective fences 1 to form a protective structure. Then, the covering mesh 2 is fixed to the inner side of the protective fence 1 through the groove connector 4, and the outer side of the groove connector 4 is locked and fixed by the locking bolts 41 to ensure that the covering mesh 2 is firmly installed on the protective fence 1.

[0031] In the specific use process, the upper plate 12 can be adjusted in vertical position according to the actual position of the pile hole, and the adjusting bolt 13 can be used to lock and fix it, so that the device can be conveniently raised and lowered, and the height can be adjusted according to different needs. It is also convenient to store it when not in use, and it is convenient to carry and place it. At the same time, the fluorescent plate 5 installed on the outer wall of the protective fence 1 and the warning light 6 on the top can play a good warning role even in an environment with insufficient light, reminding construction personnel to pay attention to the position of the hole.

[0032] When it is necessary to work on the pile hole, the device can be easily disassembled; when the work is completed, the device can be quickly reinstalled to achieve full coverage and protection of the pile hole opening, effectively preventing people or objects from falling into the hole, and improving the safety of the construction site. The design of the device not only ensures sufficient strength and stability, but also facilitates installation and disassembly, and its versatility and flexibility are also greatly improved.
