Abstract
The utility model belongs to the field of mechanical equipment, and particularly relates to a shield machine disc cutter convenient to replace. The shield machine disc cutter convenient to replace comprises a cutter shaft, a sleeve, a cutter body and a cutter ring. The sleeve is sleeved outside the cutter shaft, and the cutter ring is fixed on the outer surface of the cutter body. A bearing, an end cover, a seal ring base, a pressuring ring and an adjusting shim are sequentially arranged between the sleeve and the cutter body, the bearing is arranged between the end cover and the seal ring base, and the pressuring ring is arranged between the seal ring base and the adjusting shim. Because the sleeve is additionally arranged, quick dismantling of the disc cutter can be achieved, and thus working efficiency is improved. A check block is arranged at one end of the sleeve, so the phenomenon that the sleeve is subjected to vibration and falls off in the working process of the cutter can be prevented.
Description
Technical field
The utility model belongs to the plant equipment field, relates in particular to a kind of shield machine disk cutter of being convenient to change.
Background technology
The shield tunnel development machine, be called for short shield machine, be a kind of special engineering machinery of tunnel piercing, modern shield excavation machine light harvesting, machine,, liquid, sensing, information technology is in one, has the excavation cutting soil body, carry the soil quarrel, the assembly unit tunnel lining, measure functions such as guiding correction, relate to geology, building, machinery, mechanics, hydraulic pressure, electric, control, multi-door subject technologies such as measurement, and to carry out manufacturing and designing of " cutting the garment according to the figure " formula according to different geology, reliability requirement is high, and shield excavation machine has been widely used in subway, railway, highway, municipal administration, construction of tunnel such as water power.The cutterhead of shield machine is provided with cutter, according to engine request, cutter generally is divided into scraper, hobboing cutter and the cutter of going ahead of the rest, and wherein hobboing cutter is installed on the hobboing cutter body by a retainer ring, the hobboing cutter end of body is equipped with alloy by cutter ring, and cutter ring is installed on the hobboing cutter body by a retainer ring.
For example Chinese patent 201220127601.5 discloses a kind of shield machine hobboing cutter, comprise the hobboing cutter body, the hobboing cutter body is installed on the cutter head of shield machine by cutter shaft, it is characterized in that the centre position of hobboing cutter body is provided with the rectangle external splines, ring is provided with the rectangle internal spline in the cutter ring, ring is provided with and the corresponding keyway of external splines in the cutter ring, the appearance of hobboing cutter body is provided with and the corresponding keyway of internal spline, and cutter ring and hobboing cutter body left end adopt matched in clearance, and back-up ring is installed in cutter ring right-hand member and the welding of hobboing cutter body.
Though the disk cutter result of use of this structure is fine, be easy to wearing and tearing in actual use, especially in full section gravel stratum, probability of damage is bigger, so also need regular replacing hobboing cutter in use.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model is carried a kind of shield machine disk cutter of being convenient to change, it is characterized in that: comprise cutter shaft, sleeve, cutter hub, cutter ring, described jacket casing is in the outside of described cutter shaft, described cutter ring is fixed on the external surface of described cutter hub, be disposed with bearing, end cap, packing holder, pressure ring, adjustment pad between described sleeve and the described cutter hub, described bearing is arranged between described end cap and the described packing holder, and described pressure ring is arranged between described packing holder and the described adjustment pad.
One end of described sleeve is provided with block.
The beneficial effects of the utility model are: by increasing the setting of sleeve, can realize the fast quick-detach of disk cutter, thereby increase work efficiency, be provided with block at an end of sleeve, can prevent in the hobboing cutter course of work, thereby sleeve is vibrated the phenomenon that occurs coming off.
