[0008] As a further solution of the utility model, a mounting ring is coaxially fixed to the inner ring of the adjusting ring, and a plurality of positioning holes are provided on the mounting ring, and the positioning holes are used for inserting positioning columns provided at the bottom of the adjacent inner adjusting ring.

[0009] As a further solution of the utility model, a plurality of groups of fixing holes are installed on the fixing plate, and the fixing holes are used for inserting fixing members to fix the fixing plate outside the pile hole.

[0010] As a further solution of the utility model, the limiting rod group includes a limiting sleeve and a limiting column which are slidably connected, and the distal ends of the limiting sleeve and the limiting column are fixedly connected to the fixed disk and the bearing plate respectively.

[0011] As a further solution of the utility model, multiple groups of operating rods are fixed to the side of the rotary nut.

[0012] As a further solution of the utility model, the support frame includes a support horizontal plate and a support vertical plate, and multiple groups of the support vertical plates are fixedly installed on the bottom of the bearing plate.

[0019] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0020] like Figures 1 to 3 As shown, in an embodiment of the utility model, a pile hole protection operation platform comprises a bearing plate 1 and a fixing plate 7, wherein the bearing plate 1 and the fixing plate 7 are coaxially provided with a connecting hole for inserting a pile foundation at the center;

[0021] Wherein, a plurality of groups of adjusting rings 2 are coaxially placed in the connecting hole of the carrying plate 1, and a protective cover 3 is placed on the innermost adjusting ring 2;

[0022] The fixed plate 7 is arranged at the bottom of the bearing plate 1, and a fence 11 is coaxially installed on the inner side thereof. A plurality of limit rod groups and adjustment components are installed on the peripheral side of the fixed plate 7. The limit rod group is used to limit the lifting and lowering movement of the bearing plate 1. The adjustment component is used to adjust the spacing between the bearing plate 1 and the fixed plate 7, and includes a fixed screw 12, a rotary nut 13 and a support frame. The fixed screw 12 is vertically fixedly installed on the fixed plate 7, and the rotary nut 13 is threadedly connected to the fixed screw 12. The support frame is fixedly installed on the bottom of the bearing plate 1. A connecting hole for the fixed screw 12 to pass through is provided in the support frame, and the rotary nut 13 is used to support the lower end surface of the support frame;

[0023] Furthermore, the protective cover 3 is preferably set to a mesh structure, which can not only play a protective role, but also reduce the weight of the device, and can also facilitate observation of the pile hole. Through the setting of the bearing plate 1, a flat standing space can be provided for workers during pile construction, so that workers can perform auxiliary work around the pile hole, avoiding the safety hazards of standing directly on the muddy ground around the pile hole. At the same time, by using the fixed plate 7 as the bottom foundation, the bearing plate 1 can be kept at a certain distance from the ground, so as to prevent the bearing plate 1 from directly contacting the ground, splashing or overflowing mud and water on it, and posing safety hazards;

[0024] The provision of the enclosure 11 can further enhance the protection performance, so as to form a closed protection area on the fixed plate 7 to prevent foreign debris from falling into the pile hole.

[0025] like Figure 3As shown, in the embodiment of the utility model, the inner ring of the adjusting ring 2 is coaxially fixed with a mounting ring 4, and the mounting ring 4 is provided with a plurality of positioning holes 6, and the positioning holes 6 are used for inserting positioning columns 5 provided at the bottom of the adjacent inner adjusting ring 2. By inserting the positioning columns 5 into the positioning holes 6, the adjusting ring 2 can be limited, thereby avoiding the situation where the adjusting ring 2 rotates.

[0026] like Figure 1 As shown, in the embodiment of the utility model, a plurality of fixing holes 8 are installed on the fixing plate 7, and the fixing holes 8 are used for inserting fixing members to fix the fixing plate 7 outside the pile hole. The fixing members can be screws or the like.

[0027] like Figure 1 As shown, in an embodiment of the utility model, the limit rod group includes a limit sleeve 9 and a limit column 10 that are slidably connected. The distal ends of the limit sleeve 9 and the limit column 10 are respectively fixedly connected to the fixed plate 7 and the supporting plate 1. The limit sleeve 9 and the limit column 10 slide in cooperation with each other to improve the stability of the lifting and lowering movement of the supporting plate 1.

[0028] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, multiple groups of operating rods 16 are fixed to the side of the rotary nut 13 to facilitate the rotation operation of the rotary nut 13;

[0029] Further, the support frame includes a support transverse plate 14 and a support vertical plate 15, and a plurality of groups of the support vertical plates 15 are fixedly installed at the bottom of the bearing plate 1. The support transverse plate 14 is fixedly connected to the bottom of the support vertical plate 15, and is provided with a mounting hole for the fixing screw 12 to pass through. When the height of the bearing plate 1 needs to be adjusted, the rotating nut 13 is rotated, and the rotating nut 13 moves up and contacts with the support plate transverse plate. At this time, as the rotating nut 13 is continuously rotated on the fixing screw 12, it can gradually move up against the support transverse plate 14, thereby achieving the purpose of raising the bearing part;

[0030] Furthermore, a rotating sleeve 17 is provided at the bottom of the supporting cross plate, and the rotating sleeve 17 is used to abut against the upper end of the rotating nut 13 to reduce the friction between the rotating nut 13 and the bottom of the supporting cross plate 14 during operation, and mutually meshing positioning teeth 018 are provided on the opposite end faces of the rotating sleeve 17 and the rotating nut 13.

[0031] To sum up the above, the utility model protects the pile hole by utilizing the connecting holes arranged on the fixed plate 7 and the bearing plate 1 outside the pile hole, thereby eliminating the potential safety hazards of exposed pile holes. Through the setting of the bearing plate 1, a flat standing space can be provided for the staff to assist in the lifting of the steel cage and the construction operation of the pile, avoiding the inconvenience and potential hazards caused by standing directly on the muddy ground, and further enhancing its usability. When the height of the bearing plate 1 needs to be adjusted, the rotary nut 13 can be operated to lift the support frame to a certain height. The operation is simple and practical, and the problem that the existing pile foundation protection device can only protect the pile hole when not in construction and cannot provide a place for personnel to stand and work during construction is solved.
