Abstract
The utility model relates to a highly abrasion-resistant disk cutter which is mainly used in full-section rock tunnel boring machines, shield machines and pipe jacking equipment; the highly abrasion-resistant disk cutter is mainly characterized in that a lateral disk cutter hub protecting jacket is additionally arranged on the basis of an original disk cutter, wear-resisting layers are respectively coated and welded on the surface of the hobbing cutter hub protecting jacket and the other side surface of the hobbing cutter hub, and simultaneously the outside chamfers of the hobbing cutter hub, a hobbing cutter end cover and a hobbing cutter fastening cover are respectively improved to be in fillet transition, so as to reduce strong abrasion of the cutter surface caused by muck and macadams during working, and achieve the effect of prolonging the service life; and the utility model can be widely applied in the fields of metro constructing, tunneling and mining, and can be used in similar disk cutter tools.
Description
Technical field
The utility model relates to a kind of hobboing cutter, and more particularly, the utility model relates to a kind of high abrasion disk cutter.
Background technology
Disk cutter is mainly used in full section rock tunnel development machine, shield structure and pipe jacking equipment; At present, its structure mainly contains hobboing cutter cutter ring, hobboing cutter cutter hub, hobboing cutter fastening cover, hobboing cutter cutter shaft, cutter bearing, sealing device, hobboing cutter end cap composition; Dregs, rubble that this structure causes disk cutter behind broken rock, detritus, to form easily carry out heavy wear to unshielded cutter hub, and further cause the wearing and tearing of hobboing cutter fastening cover and hobboing cutter end cap.
Disk cutter bears huge load and impact when breaking rock, bears violent friction of rock and high temperature simultaneously, and produces a large amount of dregs, rubble; The piece surface that respectively exposes all is worn; Especially hobboing cutter cutter ring and cutter hub serious wear cause the each several part switching performance to be destroyed, and the performance of lubrication oil and rubber seal reduces; Cause cutter to lose rock breaking capacity gradually, cause scrapping of cutter.
The utility model content
The purpose of the utility model is to overcome the shortcoming of existing product, provides a kind of anti-wear performance that strengthens disk cutter to reach the high abrasion disk cutter to effective protection of disk cutter cutter hub.
The purpose of the utility model is achieved in that
At hobboing cutter cutter hub medial surface hobboing cutter cutter hub protective sleeve 7 is installed newly, and the weldering wearing layer is all covered in the another side of cutter hub protective sleeve surface and hobboing cutter cutter hub, the outside chamfering with hobboing cutter cutter hub 2, hobboing cutter end cap 8, hobboing cutter fastening cover 3 all changes round-corner transition into simultaneously.
Above-mentioned disk cutter component can adopt following layout architecture:
As shown in Figure 1, hobboing cutter cutter hub protective sleeve 7 and hobboing cutter cutter hub 2 are cooperated by 2 inner outwards connections of hobboing cutter cutter hub with interior hexagonal holding screw 9; It is excessive that fillet is all done in hobboing cutter cutter hub protective sleeve 7, hobboing cutter cutter hub 2, hobboing cutter fastening cover 3 and hobboing cutter end cap 8 outsides, all covers the weldering wearing layer at cutter hub protective sleeve surface, cutter hub protective sleeve connecting hole surface and hobboing cutter cutter hub lateral surface.
As shown in Figure 2, hobboing cutter cutter hub protective sleeve 7 and hobboing cutter cutter hub 2 are cooperated by 2 inner outwards connections of hobboing cutter cutter hub with hexagon socket cap head screw 10; It is excessive that fillet is all done in hobboing cutter cutter hub protective sleeve 7, hobboing cutter cutter hub 2, hobboing cutter fastening cover 3 and hobboing cutter end cap 8 outsides, all covers the weldering wearing layer at cutter hub protective sleeve surface, cutter hub protective sleeve connecting hole surface and hobboing cutter cutter hub lateral surface.
As shown in Figure 3, hobboing cutter cutter hub protective sleeve 7 and hobboing cutter cutter hub 2 are cooperated by 7 outside inwardly connections of hobboing cutter cutter hub protective sleeve with taper pin with internal thread 11; It is excessive that fillet is all done in hobboing cutter cutter hub protective sleeve 7, hobboing cutter cutter hub 2, hobboing cutter fastening cover 3 and hobboing cutter end cap 8 outsides, all covers the weldering wearing layer at cutter hub protective sleeve surface, cutter hub protective sleeve connecting hole surface and hobboing cutter cutter hub lateral surface.
As shown in Figure 4; Worn and torn by the brute force of dregs, rubble in the course of the work for reducing hobboing cutter cutter hub surface; Can in above scheme, carry out annular grooving in the position of hobboing cutter cutter hub mounted on surface hobboing cutter cutter hub protective sleeve 7; Cover weldering carbine abrasion-proof layer 12 then, wherein wearing layer maximum gauge≤hobboing cutter cutter ring assembles diameter, to improve the anti-wear performance of hobboing cutter cutter hub.
After the utility model adopts said structure, further strengthen the anti-wear performance of disk cutter, effectively protected hobboing cutter cutter hub again, thus the application life of having improved hobboing cutter; Hobboing cutter cutter hub has effectively been protected in the wherein use of disk cutter cutter hub protective sleeve 7, and having reduced in the course of the work, hobboing cutter cutter hub surface is reached the effect that increases the service life by the wearing and tearing of the brute force of dregs, rubble.
