Abstract
The utility model relates to a wedge-shaped hard alloy tooth conical hob device for a shaft drilling machine. Through wedge-shaped hard alloy teeth, the abrasion resistance of a hob body is improved, and the force condition of the alloy teeth is improved, so that greater pressure can be applied to a tunnel face during working, the cutting capacity of a hob is improved, and the working efficiency is improved; the device can be suitable for bad drilling environment and smooth for slagging. The hob device is formed by assembling a cutter shaft, rolling bearings, a cutter shell, the wedge-shaped hard alloy teeth, a thrust bearing, a floating seal device and the like; the wedge-shaped hard alloy teeth are irregularly arranged on the peripheral conical surface of the conical cutter shell; the cutter shell is internally provided with the two cylindrical rolling bearings in parallel coaxially. The device is simple in structure, convenient and efficient to install and use, safe to operate, time-saving, labor-saving, wear-resistant and durable, thus the cost is saved.
Description
Technical field
The utility model relates to hob device, wedge shape hard-metal insert conical hob device for especially a kind of shaft drilling machine.
Technical background
Along with the high speed development of China's mining industry and construction of tunnel, there are a large amount of mines to dig and creep into, shaft drilling machine construction method is one of main construction method of digging in this class mine.Traditional vertical shaft 12 " deslagging is unfavorable; dregs is long-pending adhering on cutter shell easily for hobboing cutter, ball toothing and arrange unreasonablely, the wearing no resistance of cutter shell, physical life is short; and also when heavy duty service, the situation stressed and sealing of hobboing cutter is bad, can not fully meet the needs of construction.
Summary of the invention
The utility model is intended to overcome the deficiency of above-mentioned technology, and wedge shape hard-metal insert conical hob device for a kind of shaft drilling machine is provided, and makes abrasion resistance, deslagging, the stress performance of hobboing cutter all obtain larger raising; Through the change of structure, when heavy duty service, the sealing performance of hobboing cutter has also had larger improvement.
For achieving the above object, the utility model adopts following technical scheme:
A wedge shape hard-metal insert conical hob device for shaft drilling machine, by: cutter shaft (1), cutter lid (2), floating seal (3), gland (4), cutter shell (5), wedge shape hard-metal insert (6), the first rolling bearing (7), thrust bearing (8), the second rolling bearing (9), hold-down bolt (11) form;
Conical cutter shell (5) periphery top is provided with wedge shape hard-metal insert (6); In cutter shell (5), be coaxially set up in parallel columnar the first rolling bearing (7), the second rolling bearing (9); Thrust bearing (8) is set between two rolling bearings; The two coaxial two ends of rolling bearing arrange cutter lid (2); Between cutter lid (2) and two rolling bearings, floating seal (3) is set; Two rolling bearings and cutter lid (2) concentric arrange cutter shaft (1); Between cutter shaft (1) and cutter shell (5), gland (4) is set; Fastening between cutter lid (2) and cutter shaft (1) realizes by hold-down bolt (11).
Described cutter shell 5 profiles are set to the taper shape of 10 ° of cone angles.
The profile of tooth of described wedge shape hard-metal insert 6 is wedge shape, and on cutter shell random being crisscross arranged.
Owing to adopting technique scheme, the utlity model has following superiority:
Through the change of structure, the abrasion resistance of hobboing cutter, deslagging, stress performance all obtain larger raising; When heavy duty service, the sealing performance of hobboing cutter has also had larger improvement.
