Abstract
The utility model discloses a roller drill shock attenuation stabilizer for mining. In order to solve the problems of poor damping and stabilizing rod effect and short service life of the existing device, the damping and stabilizing rod device adopts a butterfly spring as a damping element, and a roller and a wheel shaft are stabilizing rod elements. The slag discharge groove is arranged along the axial direction of the body. The damping element and the rod stabilizing element are combined into a whole through the body and are arranged between the drill bit and the drill rod. The utility model makes the damping and rod stabilizing device more compact; the use is more convenient; the service life is improved by 2-4 times; the holes can be drilled in the ore in excess of ten thousand meters. Meanwhile, the damping and rod stabilizing device effectively prolongs the service life of the drilling machine and the drill bit.
Description
The utility model relates to a kind of mining with the corollary equipment of rotary drill, the steady lever apparatus of particularly a kind of rig damping.
Rotary drill is in boring procedure, and drilling tool can produce high vibration, has a strong impact on the application life of drill bit, rig, and simultaneously because drill bit is bigger than drill pipe diameter, drilling rod is unstable in the hole, and the drill bit pawl back of the body is subjected to the hole wall strong wear.Therefore, for improving the application life of drill bit, drilling tool, must increase the steady lever apparatus of damping.
The damping device that uses is the rubber type damper at present, is installed between drilling rod and the rotary gear box.Steady lever apparatus adopts the reinforcing plate type virtual calibrator for instrument transformer, is installed between drill bit and the drilling rod.Because damper and virtual calibrator for instrument transformer separate, and can produce resilience ripple superposition phenomenon, the drilling tool middle part is shaken, even cause " resonance ", heavy wear rig positioning sleeve.In addition the rubber absorbers life-span low, reinforcing plate type virtual calibrator for instrument transformer and hole wall sliding friction, serious wear does not have steady bar effect soon, therefore above-mentioned damper and virtual calibrator for instrument transformer result of use are all undesirable.
The purpose of this utility model is to provide a kind of and is the damping virtual calibrator for instrument transformer of one with " damping " " steady bar " is molten, places between drill bit and the drilling rod, protects drill bit and rig effectively, prolongs its application life.
The purpose of this utility model is achieved in that
The damping virtual calibrator for instrument transformer is made of damper element and steady rod element and body, and damper element adopts butterfly spring 2, and steady rod element adopts three rollers 3, wheel shaft 4, arranges around body 1 circumference trisection.Along body shaft to three ash pits 5 are set, on this body section with the staggered five equilibrium setting of roller.Damper element and steady rod element are integrated by bulk junction.
The utility model is compared with existing same device, makes damping virtual calibrator for instrument transformer structure compact more; Use more convenient; Life-span is improved 1-2 doubly; Boring can surpass myriametre on ore.The utility model can with the caused impact of the vibration of rig and moment peak load be controlled at the bottom of the hole in the scope, its energy is effectively utilized in the broken rock operation of drill bit, do not make it upwards pass to slew gear and whole rig along drilling rod.
Fig. 1 is a damping virtual calibrator for instrument transformer overall structure schematic diagram.
Fig. 2 is the cross sectional representation of damping virtual calibrator for instrument transformer.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Damping virtual calibrator for instrument transformer major part comprises body 1, butterfly spring 2, three rollers 3 and wheel shafts 4, is smooth deslagging, and to ash pit 5 is set, ash pit is established three along body shaft, with the staggered five equilibrium setting of roller.Butterfly spring, roller, wheel shaft are contained in the body.For increasing abrasion resistance, on body, stud with alloy column 6, on roller, stud with primary alloy post 7.Auxiliary spring 8 also is housed below the butterfly spring, plays the resilience cushioning effect.Kink 9 and wear-resistant sleeve 10, following axle bed 11 also to be installed below the roller, prolong bulk lifetime.Also have top connection 12, lower contact 13 in addition on the damping virtual calibrator for instrument transformer, be fixed on roller back-up block 14 on the body, axle bed 15 on the roller, intermediate sleeve 16, bearing pin 17, underlay 18, hollow shaft 19, middle pad 20, on fill up 21, fresh air inlet 22.Whole device is installed between drill bit and the drilling rod.
