The specific embodiment
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.Need to prove that under the situation of not conflicting, the application's embodiment and the characteristic among the embodiment can make up each other.
Set forth a lot of details in the following description so that make much of the utility model, still, the utility model can also adopt and be different from other modes described here and implement, and therefore, the utility model is not limited to following disclosed specific embodiment.
To shown in Figure 7, the utility model provides a kind of borehole-enlarging drilling tool like Fig. 1, comprises expanded bore pile drill bit and the receipts slag tube 1 that is arranged at said expanded bore pile drill bit end, and said receipts slag tube 1 can be collected the slag charge that produces when said expanded bore pile drill bit carries out reaming.
The borehole-enlarging drilling tool that the utility model provides is simple in structure, installs additional in the expanded bore pile drill bit bottom of routine and receives the slag tube, not only can realize that conventional expanded bore pile expands the function at the end, and can effectively solve the problem that conventional bottom expanding drill can't effectively be received slag.Cooperate bottom little cross expanded bore pile type, be easy to rapid popularization.
In the present embodiment; Said expanded bore pile drill bit comprises: bore top 2, drill body 3, supporter 4, cornish bit 5 and scarfing cinder plate 6; One end of said scarfing cinder plate 6 is articulated in said supporter 4 bottoms; The other end and said cornish bit 5 are hinged; The other end of said cornish bit 5 is articulated in said drill body 3, and said drill body 3 is arranged at said supporter 4 tops and can sliding up and down along said supporter 4, and said drill body 3 can open said cornish bit 5 during to lower slider at the said supporter 4 in effect lower edge that bores top 2 with said scarfing cinder plate 3.
The basis of the borehole-enlarging drilling tool that the utility model provides and existing reaming rig are comparatively similar; Mainly be drill bit is put into the hole at the bottom of, after pressurization is crept into, under the vertical pressure of drilling rod; Drill body 3 can be along the chute of supporter 4 to lower slider; Four cornish bits open thereupon, and the beginning reaming proposes drill bit after the completion reaming.The dregs that scarfing cinder plate 6 produces in the time of can be with cornish bit 5 reamings is collected in the slag tube 1.
Preferably, like Fig. 3, shown in Figure 4, said receipts slag tube 1 comprises the barrel 11 and the tube end 12, an end and said barrel 11 bottom-hinged at the said tube end 12, and the other end at the said tube end 12 removably is connected with said barrel 11.
Certainly; Barrel 11 can also adopt mode as shown in Figure 5 to be connected with the tube end 12: said receipts slag tube 1 comprises the barrel 11 and the tube end 12; The bottom of said barrel 11 is provided with chute 13, can move the bottom sealing of said barrel 11 along said chute 13 in the said tube end 12.
Like this, the motion principle at the tube end is similar to drawer, can with barrel 11 sealings, receive the slag operation with in the 12 insertion chutes 13 at the bottom of the tube, after proposing hole, can 12 extractions at the bottom of the tube can be accomplished discharging, and is simple in structure, easy to operate.
As shown in Figure 2; The borehole-enlarging drilling tool that the utility model provides also comprises: the connecting rod 7 that connects said supporter 4 and said receipts slag tube 1; The upper end of said connecting rod 7 is positioned at the inside of said supporter 4 and removably is connected with said supporter 4, and the lower end of said connecting rod 7 is fixedly connected with said receipts slag tube 1.
Further, said connecting rod 7 is connected through latch 8 with said supporter 4.
Preferably; As shown in Figures 2 and 3: the lower end of said connecting rod 7 is provided with gusset 71; The barrel 11 of said receipts slag tube 1 is provided with the installing hole 110 that matches with said gusset 71, and said gusset 71 snaps in said connecting rod 7 is linked into an integrated entity with said receipts slag tube 1.
Like this, can be installed on the connecting rod 7 receiving slag tube 1 quickly and easily, only need on barrel 11, to open several installing holes 110 and can realize that gusset 71 can also be welded in the installing hole 110, it is more firm with being connected of connecting rod 7 to receive slag tube 1 like this.
Connecting rod 7 is installed on supporter 4 through latch 8, can guarantee the quickly dismantled of connecting rod 7 and supporter 4, is convenient to use the bore receipts slag tube different with length instead according to work requirements and carries out operation, helps increasing the scope of application of borehole-enlarging drilling tool.
Certainly; Can also adopt following mode to connect connecting rod 7 and receipts slag tube 1: the lower end of said connecting rod 7 is connected with the barrel 11 of said receipts slag tube 1 through the spoke of the radial radiation of the said receipts slag tube 1 in edge; One end of said spoke is fixed to said connecting rod 7, and the other end of said spoke is soldered on the barrel 11 of said receipts slag tube 1.
This spline structure is similar to the wheel of bicycle, and is gapped between the spoke, can satisfy the demand that slag charge falls, and do not influence the operate as normal of receiving the slag tube, and structure is light simultaneously, and it is little to take up room, and helps promoting the capacity utilization of receiving the slag tube.
In technique scheme, preferably, said receipts slag tube 1 adopts steel plate to process.
Because the operating mode very severe of bore operation adopts the receipts slag tube of other materials to be difficult to satisfy the operation of deep hole receipts slag, and damages easily; Influence normally carrying out of ream operation, the receipts slag tube that the utility model provides adopts the steel plate manufacturing, and is not only cheap; Intensity is high simultaneously; Weatherability is strong, helps to improve the application life of receiving the slag tube, guarantees that ream operation safe and continuous ground carries out.
The use principle of the borehole-enlarging drilling tool that the utility model provides such as Fig. 6, shown in Figure 7:
Expanding with φ 0.8m hole is that φ 1.6m hole is an example, after rig is accomplished φ 0.8m hole, drilling tool is put at the bottom of the hole, as shown in Figure 6.
Bore top 2 along with drilling rod presses down, cornish bit launches gradually, and φ 0.8m expands in the hole 1.6m for φ gradually, and scarfing cinder plate 6 is swept to the dregs in the reaming scope in the receipts slag tube 1 in the drill bit rotary course, and is as shown in Figure 7.
After reaming was accomplished, with carrying on the drill bit, drilling tool shrank, and proposed outside the hole, took out steady pin and opened a tube end 11 of receiving the slag tube and carry out slag dumping, and is as shown in Figure 4.
The technical scheme that the utility model provides has following beneficial effect: connecting rod is connected cooperation with supporting seat with receipts slag tube through gusset, and part processing is convenient, has avoided the line cutting processing, and is time saving and energy saving; The design of receipts slag tube can realize receiving slag and reaming is synchronous, and slag dumping is convenient, can increase substantially efficiency of construction and construction quality.
The utility model also provides a kind of rotary drilling rig, comprises the drilling tool in the foregoing description.
