Accompanying drawing explanation
Hereinafter, based on accompanying drawing, opening drill according to the present invention is described, in the accompanying drawings:
Fig. 1 and Fig. 2 show the side-view of opening drill, and wherein, vehicle frame is in and utilizes drilling rod and drill bit to get out plug for outlet working position before, and vehicle frame and the drilling rod position in retracting from plug for outlet region;
Fig. 3 shows the side-view of the vehicle frame of opening drill, this vehicle frame can frame bracket Linear mobile; And
Fig. 4 shows along the cross section of the line IV-IV of Fig. 3 with enlarged view.
Embodiment
According to the opening drill of Fig. 1 to Fig. 4, there is vehicle frame 1, can utilize lifting device that this vehicle frame 1 is dropped to predetermined working position and also and can from predetermined working position, be risen to idle position from idle position, in this predetermined working position, there is the predetermined distance that utilizes the plug for outlet 3 that sealing agent 4 fills with respect to smelting furnace 5 of smelting furnace side end 2.
For the drill hammer 6 that drives the drilling rod 7 with drill bit 8, can utilize and advance and retracting device moves near the end position of smelting furnace and vice versa from the end position away from smelting furnace, this advances and retracting device is embodied as the endless chain 10 being driven by oil motor 9.Centering unit 11 is fastened on the smelting furnace side end 2 of vehicle frame 1, and this centering unit 11 is embodied as plate 12, and this plate 12 has the internal point 13 for the drilling rod 7 of drilling hole burst hammer 6.
In addition, can be arranged on vehicle frame 1 along the direction of motion a of drilling rod 7, the drill stem directs device 14 that b moves, to protect drilling rod to avoid because of buckling that the ahead power compared with large causes in the driven chain 10 of drilling rod is driven into plug for outlet 3 time.
Lifting device for vehicle frame 1 is equipped with supporting arm 15, is attached with the bearer frame 16 with side guide 17 on this supporting arm 15.Be equipped with caster 19 and be fastened with thereon for the wagon box 18 of the bracket 20 of vehicle frame 1 can guide rail 17 Linears of bearer frame 16 mobile, the vehicle frame 1 so that mobile with drilling hole burst hammer 6, this drilling hole burst hammer 6 can be moved by motor on vehicle frame 1, for drilling rod 7 being moved to working position 1a and being moved out to retracted position 1b from working position, thereby the smelting furnace side end 2 that the band of protection vehicle frame 1 is useful on the centering unit 11 of drilling rod 7 is not subject to the impact of the melts 21 that leaves from unlimited plug for outlet 3, and vehicle frame 1 is moved to the 1a of working position for the process of further coming out of the stove from retracted position 1b.
Cylinder-piston unit 22 is used as the driving mechanism for wagon box 18, wherein, this cylinder-piston unit 22 is by being preferably the pressure medium actuating of hydraulic efficiency oil, the housing cylindraceous 23 of this cylinder-piston unit 22 is attached to the bearer frame 16 of opening drill and the piston rod 24 of this cylinder-piston unit 22 is bonded on the mobile wagon box 18 of vehicle frame 1, and this wagon box 18 has the bracket 20 for vehicle frame 1, this wagon box 18 can move on bearer frame 16.
For the piston rod of cylinder-piston unit 22 24 being connected to the mobile wagon box 18 of vehicle frame 1, use the engagement head 26 on the free end 25 that is screwed onto piston rod 24, this engagement head 26 is hinged on the bearing bolt 27 on the mobile wagon box 18 of being fixed on of bottom bracket 28.
For the process of coming out of the stove, first utilize the supporting arm 15 of lifting device and bearer frame 16 that vehicle frame 1 is reduced in predetermined working position.Subsequently, by cylinder-piston unit 22, vehicle frame 1 is pushed to forward final working position 1a linearly from predetermined working position, in this final working position 1a, have the distance A of the centering unit 11 from plug for outlet 3 to the smelting furnace side end 2 at vehicle frame 1, this distance A is determined by the drill bit 8 of drilling rod 7.
At the beginning of boring procedure, drilling hole burst hammer 6 is in the end position 6a away from smelting furnace.For drilling rod 7 being driven into plug for outlet 3 ahead power required and that produced by oil motor 9 of smelting furnace 5, by driving chain 10, via drilling hole burst hammer 6, be passed to drilling rod 7.If needed, the beater mechanism of drill hammer 6 can be connected in mobile arbitrary moment of advancing of drilling rod 7, to carry out drilling process.When drilling rod 7 is driven in plug for outlet 3, drilling rod 7 be fixed on vehicle frame 1 smelting furnace side end 2 places centering unit 11 and near the dangerous buckling length between the drill hammer 6 of smelting furnace 5, shorten constantly, and drill stem directs device 14 is together carried by drill hammer 6 until enter into the end position at the close smelting furnace at smelting furnace side end 2 places of vehicle frame 1, and driven chain 10 is retracted again.
The specific depth of penetration that enters into plug for outlet 3 from drilling rod 7, at this specific depth of penetration place drilling rod 7, automatically himself be positioned between two parties in the sealing agent 4 of plug for outlet 3 and no longer the centering unit 11 at smelting furnace side end 3 places of vehicle frame 1 must be positioned to be close to plug for outlet 3 thus; By cylinder-piston unit 22, vehicle frame 1 is moved back into retracted position 1b from the working position 1a near plug for outlet; and drilling rod 7 is advanced in plug for outlet 3 simultaneously, with the impact of the melts 21 protecting smelting furnace side end 2 and centering unit 11 not to be subject to leave from unlimited plug for outlet.For the process of further coming out of the stove, vehicle frame 1 utilizes cylinder-piston unit 22 to advance to the 1a of working position from retracted position 1b again.
The required withdrawal force of plug for outlet of drilling rod 7 being pulled out to smelting furnace 5 applies by oil motor 9, and is passed to drill hammer 6 and drilling rod 7 via driving chain 10.
