In sum, the utility model has the advantage of: structure is simple, excision speed is fast, and efficiency is high, effectively can reduce labour intensity; And otch is smooth, is conducive to retaining wall on slope and reduces Cutting Tool Damage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to diagram.
Detailed description of the invention
As depicted in figs. 1 and 2, header pipe joint water pressure test surplus device for excising comprises for placing the bearing 1 of header 14 and being arranged on the guide rail 2 of bearing 1 sidepiece.Described bearing 1 comprises supporting leg 11 and is connected to the strutbeam 12 at supporting leg 11 top, and the end face of strutbeam 12 is provided with the deep gouge 13 of through strutbeam 12 longitudinal direction; In actual fabrication process, available slot steel makes strutbeam 12, and the U-type groove of channel-section steel forms described deep gouge 13.Guide rail 2 slidably connects slip base 3, slip base 3 comprises sliding seat 31 and to be connected on sliding seat 31 and liftable elevating bracket 32; Being slidably connected of slip base 3 and guide rail 2 is realized by the roller 9 be connected on sliding seat 31, and namely roller 9 can roll on guide rail 2; Elevating bracket 32 is slidably connected on sliding seat 31, and the lifting of elevating bracket 32 is driven by lift drive mechanism.Elevating bracket 32 is equipped with abrasive cutoff saw 4, the output shaft of abrasive cutoff saw 4 is equipped with grinding wheel 5.
Above-mentioned lift drive mechanism can adopt rack-and-pinion elevating mechanism, and its lifter rack is located on elevating bracket 32, and lifter wheel to be rotatably connected on sliding seat 31 and by the handle drives be rotatably connected on sliding seat 31; Sliding seat 31 is bolted with the lock(ing) bolt that elevating bracket 32 can be locked.Above-mentioned lift drive mechanism can also adopt leading screw, feed screw nut's elevating mechanism, and elevating screw nut is connected on elevating bracket 32, and elevating screw to be rotatably connected on sliding seat 31 and by the handle drives be rotatably connected on sliding seat 31; Sliding seat 31 is bolted with the lock(ing) bolt that elevating bracket 32 can be locked.
Though said gear rack lifting mechanism and leading screw, feed screw nut's elevating mechanism are not shown in the drawings, those skilled in the art describe according to said structure, then without the need to spending performing creative labour just can realize.
Because the lifting of elevating bracket 32 is also infrequently carried out, lift drive mechanism can adopt following more simple and practical structure, it comprises the otic placode 10 be connected on elevating bracket 32, sliding seat 31 is bolted with the upper driving bolt 15 and lower driving bolt 16 that lean respectively on otic placode 10 end face and bottom surface.Rotating the lower bolt 16 that drives makes it in the process moved down, and elevating bracket 32 also declines thereupon, rotatably above drives bolt 15 and makes it to lean on otic placode 10, thus locked by elevating bracket 32 after elevating bracket 32 drops to certain altitude.Make if want elevating bracket 32 increase, then need first to rotate driving bolt 15 and make it away from otic placode 10, and then rotate the lower bolt 16 that drives and make it to head on otic placode 10 and move, thus realize the rising of elevating bracket 32; After elevating bracket 32 rises to certain altitude, driving bolt 15 can be screwed elevating bracket 32 is locked.
The slip of slip base 3 on guide rail 2 can be undertaken by artificial promotion, can certainly be driven by slippage driving mechanism.Described slippage driving mechanism comprises slippage drive motors 6 and the slippage that is connected with slippage drive motors 6 power drives screw mandrel 7, slip base 3 is connected with the slippage drive nut 8 driving screw mandrel 7 to be spirally connected with slippage.
