Description
Technical field
The utility model relates to a kind of knife rest, particularly relates to a kind of knife rest with shoveling and hack function.
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, 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 thereupon, cut the earth and the hack effect 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 knife rest is further improved.The applicant once applied for a kind of expansion bed plate frame with shoveling and hack function, this cutter frame structure is simple, but in actual use, there is a defective in this knife rest: owing to be fixedly hinged together between connecting rod and the cross bar, fixed angle, therefore, this knife rest hack scope is also fixed, and the scope of application is very narrow.
The utility model content
The utility model is exactly in order to solve the problems of the technologies described above, and provide a kind of have cut the earth and the expansion bed plate frame of hack function, it simple in structure, shoveling and hack are effective, can select different hack scopes according to different needs.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the knife rest with shoveling and hack function, its top is provided with the cross bar that is connected with the axle sleeve of bottom-expanding equipment, cross bar two ends and hack plate are hinged, be connected by connecting rod between hack plate and the cross bar, connecting rod and hack plate are articulated and connected, the axle of bottom-expanding equipment passes cross bar, the axle lower end of bottom-expanding equipment connects the shoveling cutter, the hack plate is by constituting with hinged square template of connecting rod and the hack ball of being located at square template end, described cross bar is provided with groove, groove is provided with the projection that the hole with the connecting rod end is complementary, the borehole jack of connecting rod end is contained on the projection, and groove is provided with baffle plate.
Described baffle plate is inserted in the groove.
Described hack plate is two.
The end of described groove is 5-10cm apart from the distance of the end of cross bar.
Advantage of the present utility model and effect are as follows:
1, the utility model is because cross bar is provided with groove, groove is provided with the projection that the hole with the connecting rod end is complementary, the borehole jack of connecting rod end is contained on the projection, groove is provided with baffle plate, the user is according to different needs, at the diverse location place of groove plug-in mounting overhead gage, just can obtain different hack scopes, use very flexible, convenient.
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, connecting rod; 4, hack cutter; 5, the axle of bottom-expanding equipment; 6, shoveling cutter; 7, groove; 8, projection; 9, baffle plate.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment 1:
As shown in Figure 1, the utility model is a kind of have cut the earth and the structure of the expansion bed plate frame of hack function as follows: the top setting be the cross bar 2 that is connected with the axle sleeve 1 of bottom-expanding equipment, cross bar 2 two ends are connected by two connecting rods 3 respectively between 4, two hack cutters 4 of a hinged hack cutter and the cross bar 2 respectively.Connecting rod 3 is articulated and connected with hack cutter 4, and hack cutter 4 is by constituting with hinged square template of connecting rod 3 and the hack ball of being located at square template end.Described cross bar 2 is provided with groove 7, and groove 7 is provided with the projection 8 that the hole with connecting rod 3 ends is complementary, and the borehole jack of connecting rod 3 ends is contained on the projection 8.Groove 7 is provided with baffle plate 9.In the present embodiment, baffle plate 9 is inserted in the groove 7.The end of groove 7 is 5cm apart from the distance of the end of cross bar 2.The axle 5 of bottom-expanding equipment passes cross bar 2, and axle 5 lower ends of bottom-expanding equipment connect shoveling cutter 6.The user is according to different needs, and baffle plate 9 is inserted into the diverse location place of groove, obtains different hack scopes.
Embodiment 2:
The end of present embodiment further groove 7 is 10cm apart from the distance of the end of cross bar 2, and other is with embodiment 1.
Embodiment 3:
The end of present embodiment further groove 7 is 8cm apart from the distance of the end of cross bar 2, and other is with embodiment 1.
