[background technology]
Down-the-hole drill is before engineering explosion, be used for holing at rock so that in boring good hole the equipment of explosive.Drilling tool is comprised of drilling rod, button bit and impactor.During boring, creep into some lengthening rods.Promote propulsive mechanism and drive reducer, chain by hydraulic motor, make slew gear and drilling tool realize lifting action.There are the following problems in actual job for prior art: in operation process because factor affecting such as the dither in impactee when work, slew gear high pulling torques, the time have between drilling rod and the drilling rod connect very firm, cause the phenomenon appearance that is difficult to normally unload bar, unload the bar efficient that wastes time and energy low, thereby have a strong impact on the normal operation of down-the-hole drill.
[summary of the invention]
For solving the problems of the technologies described above, the utility model aims to provide a kind of down-the-hole drill that hydraulic pressure unloads lever apparatus that has, and relies on this device can realize very easily unloading the bar operation.
For achieving the above object, the utility model has adopted following technical scheme, this have a down-the-hole drill that hydraulic pressure unloads lever apparatus, comprise balladeur train, and be installed in locator seat board on the balladeur train, the through hole that has an admittance drilling rod at this locator seat board, it is characterized in that: a side of balladeur train is provided with hydraulic pressure and unloads lever apparatus above described through hole, this hydraulic pressure unloads lever apparatus and is made of oil cylinder and the bar spanner that unloads that is hinged on this oil cylinder piston boom end, and this unloads the bar spanner can do the rotation campaign above described through hole under described piston rod control.
During as preferred implementation, has the dowel hole of a plurality of central distribution around described through hole in the periphery of described seat board.
During as preferred implementation, described oil cylinder is arranged on the left side of balladeur train.
Beneficial effect: compared with prior art, the utility model is after admitting balladeur train one side above the drilling rod through hole to set up hydraulic pressure to unload lever apparatus, remain static at slew gear lower, the rotation of unloading the bar spanner that utilizes hydraulic pressure to unload lever apparatus unscrews the screw thread that connects of drilling rod and drilling rod, thus the auxiliary dismounting task of finishing drilling rod very easily.
[description of drawings]
Fig. 1 is the partial structurtes schematic diagram of an embodiment of the utility model, only shows the carriage portion separation structure that down-the-hole drill is equipped with drilling rod among the figure.
Fig. 2 is the structure for amplifying schematic diagram of A section among Fig. 1.
Among the figure: balladeur train 1, slew gear 2, buffer 3, upper drilling rod 4, neck 41, oil cylinder 5, holder 51 unloads bar spanner 52, seat board 53, dowel hole 531, positioning sleeve 532, dowelled spanner 54, handle 541, alignment pin 55, lower drilling rod 6, impactor 7, drill bit 8.
[specific embodiment]
Referring to Fig. 1.Slew gear 2 is fixedly mounted on and drives chain by propulsive mechanism on the guide pass of balladeur train 1 and realize lifting.The upper end of upper drilling rod 4 is screwed on the slew gear 2 through buffer 3, and lower end and lower drilling rod 6 screw threads spin.The lower end of lower drilling rod 6 is connected with impactor 7, and button bit 8 is connected to the end of impactor 7.
Referring to Fig. 2.Being that locator is other in the lower end of balladeur train 1 arranges hydraulic pressure and unloads lever apparatus, and this hydraulic pressure unloads lever apparatus and is made of oil cylinder 5 and the bar spanner 52 that unloads that is hinged on the piston rod end of this oil cylinder 5.Oil cylinder 5 is arranged on the left side of balladeur train 1 through holder 51.This unloads bar spanner 52 can be along with the corresponding rotation campaign of the flexible work of piston rod.Seat board 53 is arranged on the front of balladeur train 1, and the middle part of seat board 53 has a through hole, and the effect of this through hole is to admit lower drilling rod 6, so that dowelled spanner 54 under the cooperation of alignment pin 55, is realized the location to lower drilling rod 6.Positioning sleeve 532 is prior art members, and its effect is the drilling rod location that adapts to different bars footpath.Unload bar spanner 52 and be positioned at the top of described seat board 53 through holes.
Described locator comprises seat board 53, dowelled spanner 54 and positioning sleeve 532.The dowel hole 531 that has a plurality of central distribution around described through hole in the periphery of seat board 53, these dowel holes 531 are located at the relative side of oil cylinder 5.The purpose of a plurality of dowel holes 531 is set, and is can adapt to the rotary position of drilling rod neck 41 and be located in order to unload bar spanner 52.The two ends of every drilling rod have respectively a neck 41 in the prior art, neck 41 is actually a location division, for dowelled spanner 54 location, its cross sectional shape is square, and the bar spanner 52 that unloads of the present utility model has utilized just existing drilling rod to have the characteristics of neck and sets up.
For further deepening understanding of the present utility model, sketching it, to unload the bar course of work as follows:
Handle rig, promote hydraulic motor by promoting reducer, chain, slew gear 2 and drilling tool are risen, the stall when neck 41 of drilling rod 6 upper ends arrives seat board 53 through holes top instantly.Then in the steps below operation:
1, the neck 41 of upper drilling rod 4 lower ends is gone to and unload the corresponding position of bar spanner 52 bayonet sockets, unload bar spanner 52 and stick into neck, and make the piston rod of oil cylinder 5 be reduced to the end.
2, dowelled spanner 54 is snapped in the neck of lower drilling rod 6 upper ends, select suitable dowel hole 531 and insert alignment pin 55, lower drilling rod 6 can not be rotated counterclockwise.
