Abstract
The utility model relates to the improved structure of a foundation pile cutting tool used for foundational civil engineering. A plurality of tool aprons are arranged on a nozzle of a tubular body in a circular way, and a plurality of tungsten steel cutting tools are installed on the tool aprons. The utility model is characterized in that a notch is arranged above each of the inverse T-shaped tool aprons, and one slablike tungsten steel cutting tool is respectively fixed in each of the notches; as each of the slablike tungsten steel cutting tools is respectively and horizontally arranged on the tangential direction of the tubular body to dredge, the back side of each of the tungsten steel cutting tools still leans on the interior of each of the notches to dredge and can not fall if a front part of each of the tool aprons is worn out during the operation of rotary dredging; thus, the service life of each of the tool aprons can be extended, and the tool aprons do not need frequent replacing.
Description
The utility model relates to the foundation pile cutter that the building Foundation Design is used, and refers to that especially a kind of tool rest of foundation pile is provided with a notch, is fixed with the cutter of a tabular wolfram steel cutter in notch.
When general civil engineering was excavated foundation pile, Arranged rings was provided with several tool rests a on the mouth of pipe of a tubular body, and is equiped with several wolfram steel cuttves b on tool rest a; Tubular body by rotation excavates the tool rest a on its below pipe end on the ground, as shown in Figure 4, wolfram steel cutter b is a column, and on the appropriate location of tool rest a, be drilled with several shallow bore hole holes a1, again wolfram steel cutter b is welded in the a1 of shallow bore hole hole, make wolfram steel cutter b expose hole, but the higher wolfram steel cutter b of mat hardness excavate.Because position main when excavating is at wolfram steel cutter b, it on the tool rest a cutting position, tool rest a still can run into native stone in mining process, just the non-cutting that gets tool rest a partly can be decreased by native stone mill, hole a1 the place ahead of installing wolfram steel cutter b is revealed because of tool rest a wearing and tearing, because of wolfram steel cutter b is cylindric, in case the outside of hole a1 is worn, wolfram steel cutter b because of being worn, tool rest a is come off when excavating, in case coming off, wolfram steel cutter b just can't carry out excacation, must be again with wolfram steel cutter b repair welding on the position that comes off, if tool rest a heavy wear must wholely change; Because of tool rest a is that mode with welding is fixed on the port of tubular body, so need will change tool rest a the time to melt weld with oxy-acetylene, tool rest a takes off in the side, therefore, and very trouble inconvenience in the work of changing the outfit.Moreover, because the native stone on the face of land is hard material, so tubular body must excavate with high rotating speed, and the diameter of tubular body is very big, therefore the cutting linear velocity of tool rest a is very high, makes the situation of tool rest wearing and tearing very serious, so must change tool rest a often in digging operation, thereby reduced the progress of excavating, influence follow-up engineer operation.
The purpose of this utility model is to provide a kind of structure-improved of foundation pile cutter, makes it to prevent that cutter head from coming off, and reduces the wearing and tearing of the cutter head and the non-cutting tip of cutter preferably, thereby can prolong the application life of tool rest, does not take normal replacing tool rest.
The utility model is to realize like this, Arranged rings is provided with several tool rests on the mouth of pipe of a tubular body, and on tool rest, be equiped with several wolfram steel cuttves, be characterized in: tool rest is the inverted T-shaped shape, be provided with a notch above it, in notch, be fixed with a tabular wolfram steel cutter, and on the tool rest lateral surface of inverted T-shaped shape, be equiped with the wolfram steel cutter of several short cylinder.
The utility model has the advantages that: because tabular wolfram steel cutter is to be horizontally set with in the tangential direction of tubulose to excavate, when if tool rest the place ahead is worn when rotation is excavated, the back side of wolfram steel cutter still can lean against excavates in the notch and can not come off, thereby can prolong application life of tool rest, do not take normal replacing tool rest, save construction cost, and shorten the excavation time, quicken the process of digging operation.
Below in conjunction with accompanying drawing structure technology feature of the present utility model is described further.
Description of drawings:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is a lateral view of the present utility model.
Fig. 3 is an assembling schematic perspective view of the present utility model.
Fig. 4 is the three-dimensional exploded view of known technology.
See also Fig. 1, Fig. 2 and Fig. 3, Arranged rings is provided with several tool rests 2 on the mouth of pipe of a tubular body 1, and is equiped with several wolfram steel cuttves 3 on tool rest 2, and it is characterized in that: tool rest 2 is the inverted T-shaped shape, be provided with a notch 21 above it, in notch 21, be fixed with a tabular wolfram steel cutter 3.
According to above-mentioned structure, because tabular wolfram steel cutter 3 is to be horizontally set with in the tangential direction of tubular body 1 to excavate, when if tool rest 2 the place aheads are decreased by native stone mill in the rotation excavation, the back side of wolfram steel cutter 3 can't touch native stone, so not having the situation of wearing and tearing takes place, and, the fixed-area of tabular wolfram steel cutter 3 is bigger, even decreased by native stone mill in notch 21 excavation direction the place aheads, the back side of wolfram steel cutter 3 still can fixedly lean against in the notch 21, and it can not come off when excavating, therefore can prolong the application life of tool rest 2, do not take normal replacing tool rest 2,, quicken the process of digging operation to shorten the excavation time.
Moreover, owing to do not take normal replacing tool rest 2, thus can save consumptive tool rest 2, to save the cost of construction.
See also again shown in Figure 2, on tool rest 2 lateral surfaces of inverted T-shaped shape, be equiped with the wolfram steel cutter 3 of several short cylinder ', make its effect that excavation also can be arranged on lateral surface, and can protect the back side of tool rest 2.
