Description
Technical field
The utility model relates to a kind of knife rest, particularly relates to a kind of bottom-expanding equipment that is applicable to and has the special tool-post of 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.For this reason, the applicant once applied for having and cut the earth and the Chinese utility model patent of the bottom-expanding equipment special tool-post of hack function, this cutter frame structure is simple, but there is a defective in actual use: because the connected mode for being fixedly hinged between axle and the connecting rod, fixed angle, the hack narrow range is used and is limited to.
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 bottom-expanding equipment special tool-post of hack function, it simple in structure, 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: multi-functional bottom-expanding equipment knife rest, 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, the axle of bottom-expanding equipment passes cross bar, be connected by connecting rod between the axle of hack plate and bottom-expanding equipment, connecting rod and hack plate are articulated and connected, the axle lower end of bottom-expanding equipment connects the shoveling cutter, axle is provided with groove, groove is provided with the projection that the hole with the connecting rod end is complementary, and 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.
Distance between described groove and the cross bar is 5-10cm, and the distance between the shoveling cutter is 5-10cm.
Advantage of the present utility model and effect are as follows:
1, the utility model is because axle is provided with groove, and groove is provided with the projection that the hole with the connecting rod end is complementary, and the borehole jack of connecting rod end is contained on the projection.Be fitted with baffle plate on the groove,, baffle plate be inserted into the diverse location place of groove,, use to obtain different hack scopes according to user's different needs
Come very convenient, flexible.
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 plate; 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.
As shown in Figure 1, the utlity model has cut the earth and the structure of the bottom-expanding equipment special tool-post 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 a hinged hack plate 4 respectively, the axle 5 of bottom-expanding equipment pass 2, two hack plates 4 of cross bar and bottom-expanding equipment spools 5 between be connected by two connecting rods 3 respectively.Is connected 3 by connecting rod between the axle 5 of hack plate 4 and bottom-expanding equipment, connecting rod 3 is articulated and connected with hack plate 4, and axle 5 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 protruding 8.Groove 7 is provided with baffle plate 9, and baffle plate 9 is inserted in the groove 7 in the present embodiment.Axle 5 lower ends of bottom-expanding equipment connect shoveling cutter 6.Distance between described groove 7 and the cross bar 2 is 5-10cm, and the distance between the shoveling cutter 6 is 5-10cm.The user is according to different needs, baffle plate 9 is inserted into diverse location place on the groove 7, to obtain different hack scopes.
