The slag bucket moves up and down along the manhole. After the path is limited, it is convenient to lift it out from the top, and it is also easy to judge from the bottom, and it is not easy to cause a smashing accident, thus realizing the function of limiting the upper and lower positions of the slag bucket;

[0017] (3) By providing a square tube, a support column, a bottom support plate, a positioning screw eye and a positioning bolt, when in use, the height of the support column can be adjusted according to the height of the excavator, the positioning bolt is pulled out, and the bottom support plate contacts the bottom of the pile hole. As the bottom frame rises and falls, the support column moves up and down along the inside of the square tube to be adjusted to a suitable height, and the positioning bolt is driven in. The positioning bolt is driven into the positioning screw eye at the corresponding position, and the height of the support column is limited. The support column cooperates with the four sets of slings above to further improve the stability and load-bearing capacity of the bottom frame, thereby realizing the function of facilitating the adjustment of the support height.

[0026] The bottom end of the support rod 3 is connected to the top end of the bottom support frame 1, the vertical center lines of the bottom support frame 1, the top support frame 4, and the bottom frame 11 coincide with each other, the first pulley 5, the second pulley 7, and the third pulley 8 have the same specifications, the first pulley 5, the second pulley 7, the third pulley 8 and the sling 9 are adapted, the lifting ring 10 is symmetrically distributed about the vertical center line of the bottom frame 11, the sling 9 and the lifting ring 10 are movably connected, the protective component has high structural strength, and the height is adjustable;

[0027] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the bottom frame 11 is lowered into the pile hole by the sling 9, and the construction workers who are digging the hole can directly descend to the bottom of the pile hole by standing on the bottom frame 11. The bottom frame 11 stops descending about one and a half meters away from the bottom of the pile hole, and the protective cover 14 is opened by grasping the handle 16. The digging workers can go down from the entrance 13 to the bottom of the steel protective net 12 to dig the pile hole. As the digging progresses, the bottom frame 11 is slowly lowered, and the excavated debris is lifted upward through the debris bucket. When the hole wall collapses, the debris bucket falls, etc., the pile hole protective frame composed of the bottom frame 11 and the steel protective net 12 can block the construction workers' heads, reducing the chance of injury to the construction workers.

[0028] The manhole 13 passes through the upper and lower ends of the steel protection net 12, the area of ​​the protection cover 14 is larger than the opening of the manhole 13, the bottom end of the blocking block 15 is lower than the bottom end of the protection cover 14, the steel protection net 12 and the blocking block 15 are not connected, the upper and lower positions of the slag bucket are limited, and the risks are easier to control;

[0029] Specifically, Figure 1 and Figure 3 As shown, during the excavation process, the protective cover 14 is closed, and the blocking block 15 can support the protective cover 14 to leave a gap so that it is convenient to push it open from the bottom. The slag bucket moves up and down along the passage 13. After the path is defined, it is convenient to lift it out from the top and it is easy to judge from the bottom, so accidents of being hit are not likely to occur.

[0030] A square tube 17 is welded at the middle position inside the bottom frame 11, and two groups of positioning bolts 21 are inserted on the right side of the square tube 17. A support column 18 is vertically arranged inside the square tube 17, and a bottom support plate 19 is welded at the bottom end of the support column 18.

The positioning bolts 21 penetrate the square tube 17 and extend into the interior of the positioning screw eyes 20. The positioning screw eyes 20 are arranged at equal intervals, which is convenient for adjusting the height of the bottom support;

[0031] Specifically, Figure 1 and Figure 4As shown, the positioning bolts 21 are pulled out, and the bottom support plate 19 contacts the bottom of the pile hole. As the bottom frame 11 rises and falls, the support column 18 moves up and down along the inside of the square tube 17, and is adjusted to a suitable height. The positioning bolts 21 are driven in, and the positioning bolts 21 are driven into the positioning screw eyes 20 at the corresponding positions. The height of the support column 18 is limited. The support column 18 cooperates with the four groups of slings 9 above to further improve the stability and load-bearing capacity of the bottom frame 11.

[0032] Working principle: When the utility model is in use, first, the bottom support frame 1, the support rod 3, and the top support frame 4 constitute a ground support frame, and the bottom frame 11 and the steel protection net 12 constitute a pile hole protection frame. The bottom frame 11 is lowered into the pile hole by the sling 9, and the construction personnel who dig the hole can directly descend to the bottom of the pile hole by standing on the bottom frame 11. The bottom frame 11 stops descending about one and a half meters from the bottom of the pile hole, and the protection cover 14 is opened by grabbing the handle 16. The hole diggers can go down from the entrance 13 to the bottom of the steel protection net 12 to dig the pile hole. As the excavation proceeds, the bottom frame 11 is slowly lowered, and the excavated debris is lifted upward through the debris bucket. When the hole wall collapses, the debris bucket falls, etc., the pile hole protection frame composed of the bottom frame 11 and the steel protection net 12 can block the construction personnel's heads, reducing the chance of injury to the construction personnel. In addition to being a passage for people to pass through, the passage 13 is also used for lifting out the slag bucket. During the excavation process, the protective cover 14 is closed, and the blocking block 15 can support the protective cover 14 to leave a gap so that it can be pushed open from the bottom. The slag bucket moves up and down along the passage 13. After the path is limited, it is convenient to lift it out from the top, and it is also easy to judge from the bottom, so it is not easy to cause a hit accident. According to the height of the excavator, the height of the support column 18 can be adjusted, and the positioning bolt 21 can be pulled out. The bottom support plate 19 contacts the bottom of the pile hole. As the bottom frame 11 rises and falls, the support column 18 moves up and down along the inside of the square tube 17 to an appropriate height, and the positioning bolt 21 is driven in. The positioning bolt 21 is driven into the positioning screw eye 20 at the corresponding position, and the height of the support column 18 is limited. The support column 18 cooperates with the four groups of slings 9 above to further improve the stability and load-bearing capacity of the bottom frame 11.
