Utility model content
Technical problem to be solved in the utility model is the problem that deformation easily occurs drilling machine drilling rod pipe box at work, and provides a kind of drilling machine drilling rod pipe box for this problem.
A kind of drilling machine drilling rod pipe box described in the utility model, comprise the drilling rod pipe box body and two pins that entangle drilling machine drilling rod, described drilling machine drilling rod pipe box body becomes square column type, four sides of drilling machine drilling rod pipe box body are equipped with two through holes that pass for pin, it is characterized in that described drilling rod pipe box body one end is provided with the square follow block that props up drilling machine drilling rod, described square follow block and drilling rod pipe box body are structure as a whole, and square follow block middle part has the square follow block through hole that is communicated with drilling rod pipe box body interior.
The utility model is provided with in described drilling rod pipe box body one end the square follow block being structure as a whole with drilling rod pipe box body, described square follow block props up the insertion end of drilling rod after drilling machine drilling rod inserts drilling rod pipe box body, thereby in the time of drilling rod punching press and/or rotation, can be distributed on the square follow block of drilling rod pipe box body one end to the stamping press that major general's part is applied on drilling rod, alleviate the pressure of two pins, pin, the probability of two pin via hole generation deformation on two through hole and drilling rods that pass for pin on drilling rod pipe box body reduces greatly, improve revolving of rotary drilling rig and dig efficiency, increase described drilling bit of rotary-digging drilling rig seat, the application life of pin and drilling machine drilling rod.
Further, the bore of described square follow block through hole is 120mm, and the internal diameter that described drilling rod pipe box body is provided with square follow block one end is 206mm, and drilling machine drilling rod pipe box and follow block are made by 35# mild steel;
The thickness of described base plate is 40mm.
Accompanying drawing explanation
Fig. 1 is the structural representation (containing part drilling machine drilling rod, not showing the pin via hole on two pins and drilling machine drilling rod) of a kind of drilling machine drilling rod pipe box described in prior art;
Fig. 2 is the structural representation (containing part drilling machine drilling rod, not showing the pin via hole on two pins and drilling machine drilling rod) of a kind of drilling machine drilling rod pipe box described in embodiment.
The specific embodiment
See Fig. 1, drilling machine drilling rod pipe box described in prior art, comprise the drilling rod pipe box body 1 and two pins that entangle drilling machine drilling rod 2, drilling rod pipe box body 1 is provided with the through hole 3 passing for pin, when use, drilling machine drilling rod 2 inserts drilling rod pipe box body 1, and the pin via hole on drilling machine drilling rod 2 is alignd with the through hole on drilling rod pipe box body 1, then insert two pins, and insert cottor pin at the end of two pins, but as described in utility model content part, this structure is all applied to the twisting resistance and the stamping press that make drilling machine drilling rod 2 pass to drilling machine drilling rod pipe box 1 on two pins, easily make pin, two pin via hole generation deformation on the through hole 3 and the drilling rod 2 that pass for pin on drilling rod pipe box body 1.
Described in this specific embodiment, drilling machine drilling rod pipe box is on the basis of existing described drilling machine drilling rod pipe box, be provided with the square follow block that props up drilling machine drilling rod in one end of drilling rod pipe box body, square follow block and drilling rod pipe box body are structure as a whole, insert after drilling rod pipe box body at drilling machine drilling rod, described square follow block props up the insertion end of drilling machine drilling rod, have at least part drilling rod to be dispersed on square follow block the stamping press of drilling rod pipe box body, reduced the suffered mechanical pressure of pin.
In actual application, drilling rod needs to replace according to revolving the situation of digging object, and before another suitable drilling rod inserts drilling machine drilling rod pipe box, described drilling rod pipe box has native slag and enters, therefore, this specific embodiment has been opened the square follow block through hole of a connection drilling rod pipe box body interior at described square follow block middle part.
As stated in the Background Art, twisting resistance and stamping press that drilling rod passes to drilling rod pipe box body can reach the pressure that is equivalent to 40 tons conventionally, if and that square follow block through hole is opened is excessive, although being conducive to enter the intrinsic native slag of drilling rod pipe box discharges from square follow block through hole, but square follow block disperses the ability of pin stamping press just weakened, in fact, under extreme case, may also can there is deformation in square follow block, on the other hand, if it is too small that square follow block through hole is opened, soil slag will be trapped in drilling rod pipe box body, and affect follow-up drilling rod and insert drilling rod pipe box body.
In addition, this specific embodiment is set up square follow block in drilling rod pipe box body one end need to increase materials, therefore, another problem of the required consideration of this specific embodiment is: in the situation that guaranteeing the minimum level of materials, how to improve square follow block and disperse drilling rod to pass to the ability of at least part of stamping press of drilling rod pipe box body.Under identical square follow block materials, increase the thickness that the bore of square follow block through hole will the square follow block of corresponding increase, this dispersibility to square follow block stamping press has two rightabout effects: first, the contact surface of drilling rod and square follow block reduces, in order to maintain the ability of disperseing stamping press, the pressure that drilling rod is applied on square follow block will increase, and square follow block more likely holds be can't stand such pressure and occurs deformation or fracture; The second, the thickness of square follow block increases, and this is applied to the larger pressure on square follow block by making square follow block can bear drilling rod.The internal diameter that is provided with square follow block one end in view of drilling rod pipe box body is 206mm, drilling machine drilling rod pipe box and square follow block are made by 35# mild steel, this specific embodiment is found, only have the bore of square follow block through hole is set as to 120mm, could meet native slag can not be trapped in drilling rod pipe box body, can guarantee again in the minimum situation of materials, make square follow block disperse 15 tons of maximum stamping presses, in fact, now, pin only bears the twisting resistance that drilling rod applies, all stamping presses bear by square follow block, and the thickness of square follow block is 40mm.
