Description
Technical field
The utility model relates to a kind of knife rest, particularly relates to a kind of knife rest that is applicable to that bottom-expanding equipment is used.
Background technology
Along with the development gradually of builing industry, the construction of high-rise building is more and more, and highrise building also is more and more higher to the demands for bearing capacity of ground.In order to increase single pile bearing capacity, prior art is to adopt expanded bore pile to improve bearing capacity of single pile, and it can also reduce cost simultaneously.Also arise at the historic moment for cooperating expanded bore pile to expand end shoveling equipment.But present bottom-expanding equipment cutter frame structure is very complicated, and the shoveling effect is also undesirable, owing to the structure of knife rest makes applying of bottom-expanding equipment be subjected to certain limitation.Therefore be badly in need of the existing end of expanding is further improved with knife rest.The applicant once applied for a kind of Chinese utility model patent that expands the end with knife rest for this reason, and this cutter frame structure is simple, and shoveling and hack are effective, but because the hack plate of this knife rest is fixedly hinged on the shoveling cutter, the hack scope is fixed, narrow application range.
The utility model content
The utility model is exactly in order to solve the problems of the technologies described above, and a kind of bottom-expanding equipment knife rest is provided, it simple in structure, and shoveling and hack are effective, can select different hack scopes according to user's needs.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of bottom-expanding equipment knife rest, comprise that the top is provided with the cross bar that is connected with the axle sleeve of bottom-expanding equipment, the axle of bottom-expanding equipment passes cross bar, the axle lower end of bottom-expanding equipment connects the shoveling cutter, have groove on the described shoveling cutter, groove be provided with the hack plate on the projection that is complementary of hole, borehole jack on the hack plate is contained on the projection, the hack plate is to be made of square template and the hack ball of being located at square template end, and groove is provided with baffle plate.
Described baffle plate is inserted in the groove.
Described hack plate is two.
The distance of the distance from top shoveling cutter of described groove is 5-10cm, and the distance of the distance from bottom shoveling cutter of described groove is 5-10cm.
Advantage of the present utility model and effect are as follows:
1, the utility model compared with prior art, owing on the shoveling cutter, have groove, groove be provided with the hack plate on the projection that is complementary of hole, borehole jack on the hack plate is contained on the projection, and groove is provided with baffle plate, according to user's needs, appropriate position on groove is provided with baffle plate, the hack scope that selection needs, use is flexible, convenient, and the scope of application is wide.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, the axle sleeve of bottom-expanding equipment; 2, cross bar; 3, the axle of bottom-expanding equipment; 4, hack plate; 5, shoveling cutter; 6, groove; 7, projection; 8, baffle plate.
