The device can also be reused, which improves utilization.

[0023] See also Figure 1 In the above embodiment, the protective frame 1 includes: four protective bodies 11 and a plurality of connecting bodies 12. Among them, each protective body 11 is connected end to end in sequence, and each protective body 11 is vertically connected to the adjacent protective body 11, and the four protective bodies 11 form a rectangular frame. Specifically, the four protective bodies 11 can be divided into two first protective bodies arranged in parallel and two second protective bodies arranged in parallel, and the two ends of each first protective body 11 are vertically connected to the corresponding ends of the two second protective bodies 11. In specific implementation, the two adjacent protective bodies 11 can be welded.

[0024] Each connector 12 is arranged along the length direction of the rectangular frame ( Figure 1 The two connecting bodies 12 are arranged in a rectangular frame at intervals in the direction a shown in the figure. Both ends of each connecting body 12 are perpendicular to and detachably connected to the two protecting bodies 11 in the length direction of the rectangular frame. Specifically, the two protecting bodies 11 in the length direction of the rectangular frame can be recorded as two first protecting bodies, and the two protecting bodies 11 in the width direction ( Figure 1 The two protective bodies 11 on the b direction shown in the figure can be recorded as two second protective bodies, and each connector 12 is arranged at intervals along the length direction of the first protective body. Each connector 12 is arranged in parallel, that is, each connector 12 is parallel to the second protective body (that is, each connector 12 is parallel to the width direction of the rectangular frame), then each connector 12 is perpendicular to the first protective body (that is, each connector 12 is perpendicular to the length direction of the rectangular frame), and the two ends of each connector 12 are detachably connected to the two first protective bodies.

[0025] In a specific implementation, each protective body 11 and each connector 12 can be a 25*25*1.5 galvanized square tube. The distance between two adjacent connectors 12 can be 200 mm.

[0026] It can be seen that in this embodiment, the four protective bodies 11 are connected end to end in sequence to form a rectangular frame body. The connecting bodies 12 are arranged in parallel within the rectangular frame body, capable of supporting the rectangular frame body and enhancing the strength of the rectangular frame body, thereby improving the strength and stability of the protective frame 1.

[0027] Preferably, the connection between two adjacent protective bodies 11 is detachable, facilitating the installation and disassembly of the protective frame 1, saving labor, and improving construction efficiency. Specifically, two adjacent protective bodies 11 are connected by bolts. Of course, other detachable connection methods are also possible, and this embodiment does not impose any restrictions on this.

[0028] See Figures 1 to 2 , in the above embodiments, each protective body 11 and each connecting body 12 are both structures that can be telescopic by themselves.

[0029] Each protective body 11 includes: a protective cylinder 111, a protective rod 112, and a first locking bolt 113. Among them, the inside of the protective cylinder 111 is hollow, and both ends of the protective cylinder 111 are open ends. The first end of the protective cylinder 111 is detachably connected to the first end of the protective rod 112 of the adjacent protective body 11, such as by bolt connection. The second end of the protective rod 112 is movably inserted into the protective cylinder 111 from the second end of the protective cylinder 111. Specifically, the cross-sectional shape of the protective rod 112 matches the cross-sectional shape of the protective cylinder 111, and the cross-sectional dimension of the protective rod 112 is smaller than the cross-sectional dimension of the protective cylinder 111, so as to facilitate the insertion of the protective rod 112 into the protective cylinder 111.

[0030] A first threaded hole is provided on the side wall of the second end of the protective cylinder 111. The first locking bolt 113 passes through and is screwed into the first threaded hole, and the end of the first locking bolt 113 abuts against the protective rod 112. Specifically, after adjusting the depth of insertion of the protective rod 112 into the protective cylinder 111, the first locking bolt 113 is screwed into the first threaded hole and its end abuts against the protective rod 112, so that the protective rod 112 is fixed in the protective cylinder 111.

[0031] Each connecting body 12 includes: a connecting cylinder 121, a connecting rod 122, and a second locking bolt 123. Among them, the inside of the connecting cylinder 121 is hollow, and both ends of the connecting cylinder 121 are open ends. The first end of the connecting cylinder 121 is perpendicular to the protective cylinder 111, and the first end of the connecting cylinder 121 is detachably connected to the protective cylinder 111, such as by bolt connection.

[0032] The first end of the connecting rod 122 is perpendicular to the opposite protective rod 112, and the first end of the connecting rod 122 is detachably connected to the opposite protective rod 112, such as by bolt connection. Specifically, among the two protective bodies 11 corresponding to the two ends of the connecting body 12, the protective cylinder 111 of one of the protective bodies 11 corresponds to the protective rod 112 of the other protective body 11. Then, the first end of the connecting cylinder 121 is detachably connected to the protective cylinder 111 of one of the protective bodies 11, and the first end of the connecting rod 122 is detachably connected to the protective rod 112 of the other protective body 11.

[0033] The second end of the connecting rod 122 is movably inserted into the connecting cylinder 121 from the second end of the connecting cylinder 121. Specifically, the cross-sectional shape of the connecting rod 122 matches the cross-sectional shape of the connecting cylinder 121, and the cross-sectional dimension of the connecting rod 122 is smaller than the cross-sectional dimension of the connecting cylinder 121, so as to facilitate the insertion of the connecting rod 122 into the connecting cylinder 121.

[0034] A second threaded hole is provided in the side wall of the second end of the connecting cylinder 121. The second locking bolt 123 is inserted through and screwed into the second threaded hole, and the end of the second locking bolt 123 abuts against the connecting rod 122. Specifically, after adjusting the depth of insertion of the connecting rod 122 into the connecting cylinder 121, the second locking bolt 123 is screwed into the second threaded hole and its end abuts against the connecting rod 122, so that the connecting rod 122 is fixed in the connecting cylinder 121.

[0035] It can be seen that in this embodiment, each protective body 11 is a self-expandable structure, so that the length of the protective body 11 can be adjusted according to the size of the pile hole 3, thereby better protecting the pile hole. When the protective body 11 expands or contracts itself to adjust its length, each connecting body 12 is a self-expandable structure. In this way, the length of the connecting body 12 can be adjusted according to the size of the protective frame 1, so as to support the protective frame 1 and improve the strength of the protective frame 1.

[0036] See Figure 1 and Figure 3 In the above embodiments, the hoisting mechanism 2 includes: four hoisting bodies 21. Among them, each hoisting body 21 is in an inclined state. The first ends of the four hoisting bodies 21 respectively correspond to the two ends of the two protective bodies 11 placed in the length direction. The first end of each hoisting body 21 is detachably connected to the corresponding end of the corresponding protective body 11, and the second ends of the four hoisting bodies 21 converge together and are detachably connected.

[0037] Preferably, the first end of each hoisting body 21 is bolted to the corresponding end of the corresponding protective body 11, and the second ends of the four hoisting bodies 21 are bolted together. Specifically, threaded holes are provided on the inner side of each end of the protective body 11 connected to the hoisting body 21 facing the inside of the protective frame 1. The first end of each hoisting body 21 is screwed to the corresponding threaded hole of the corresponding end of the corresponding protective body 11 through a bolt to achieve the connection.

[0038] In specific implementation, each hoisting body 21 can be a DN15 galvanized round pipe with a length of 800 mm. The two ends of the galvanized round pipe are made into flat heads and bent at a certain angle. The first end of each hoisting body 21 is fixed to the protective body 11 through an M10 bolt, and the second ends of the hoisting bodies 21 are connected and fixed through M10 bolts.

[0039] It can be seen that in this embodiment, the protective frame 1 is a rectangular frame body, the hoisting bodies 21 are in an inclined state, the first ends of the four hoisting bodies 21 are respectively placed at the four corners of the rectangular frame body, and the second ends of the four hoisting bodies 21 converge and are detachably connected together. The structure of the hoisting mechanism 2 is simple, easy to implement, and can ensure the stability between the protective frame 1 and the hoisting mechanism 2, improving the stability and firmness.

[0040] In the above embodiments, each hoisting body 21 can be telescopic. When the protective body 11 in the protective frame 1 is telescoped to adjust the length of the protective body 11, in order to adapt to the protective frame 1, the length of the hoisting body 21 is adjusted, so as to better hoist the protective frame 1.

[0041] Each hoisting body 21 includes: a hoisting cylinder, a hoisting rod and a third locking bolt. Among them, the inside of the hoisting cylinder is hollow, and both ends of the hoisting cylinder are open ends. The first end of the hoisting cylinder is detachably connected to the corresponding end of the corresponding protective body 11, such as bolt connection. The first end of the hoisting rod is detachably connected to the first ends of the hoisting rods of the other hoisting bodies 21, so that the first ends of the hoisting rods in the four hoisting bodies 21 converge and are detachably connected.

[0042] In specific implementation, among the four hoisting bodies 21, the first ends of two of the hoisting cylinders are detachably connected to the first ends of the protective cylinders 111 of the corresponding protective bodies 11, and the first ends of the other two hoisting cylinders are detachably connected to the first ends of the protective rods 112 of the corresponding protective bodies 11.

[0043] The second end of the hoisting rod is movably inserted into the hoisting cylinder from the second end of the hoisting cylinder. Specifically, the cross-sectional shape of the hoisting cylinder matches the cross-sectional shape of the hoisting rod, and the cross-sectional dimension of the hoisting rod is smaller than the cross-sectional dimension of the hoisting cylinder, so as to facilitate the hoisting rod to be inserted into the hoisting cylinder.

[0044] A third threaded hole is formed on the side wall of the second end of the hanging tube, a third locking bolt is passed through and screwed into the third threaded hole, and the end of the third locking bolt abuts against the hanging rod. Specifically, after adjusting the depth of the hanging rod inserted into the hanging tube, the third locking bolt is screwed into the third threaded hole and its end abuts against the hanging rod, so that the hanging rod is fixed in the hanging tube.

[0045] It can be seen that, in this embodiment, each hanging body 21 has a simple structure and is easy to implement.

[0046] In summary, in the present embodiment, the protective frame 1 is placed above the pile hole 3, thereby temporarily protecting the pile hole 3 and effectively protecting the pile hole 3, and the lifting mechanism 2 lifts the protective frame 1, which is convenient for lifting and transportation of the protective frame 1.

The operation is simple, which saves labor and installation time, and improves construction efficiency. The device can also be reused, which improves utilization, saves resources, and saves costs.

[0047] When in use, the protective frame 1 is connected to the hoisting mechanism 2. After the pile driving is completed, the pile hole protective device is placed above the pile hole 3 to protect the pile hole 3. After use, the pile hole protective device is moved to the placement area for the convenience of new pile holes 3. After the pile driving construction is completed, the protective frame 1 and the hoisting mechanism 2 are disassembled into modular components for easy transportation and reuse in other projects. After disassembly, it occupies a small space and is easy to transport, saving transportation costs. The protective device can protect the pile hole 3, effectively protect the pile hole 3, so that the pile hole 3 can be backfilled in batches, improve the efficiency of the pile hole 3 backfilling, and save the machine shift cost of the pile hole 3 backfilling.
