Abstract
The invention discloses a device for detecting wear information of a replaceable cutter for a shield machine, and belongs to the field of shield machines for tunnel construction. The device is structurally characterized in that a cylindrical blind hole 7 is formed in a replaceable cutter rest 2 and a cutter head 4, the cylindrical blind hole 7 is positioned between two alloys 5 and 6 at two ends of the cutter head, and an effective distance is formed between the top of the cylindrical blind hole 7 and the top surface of the rectangular cutter head. Wear of the cutter is detected in the construction process according to whether a detection hole is worn through, so that the time for halting and replacing the cutter is mastered. The device is simple in structure, low in cost, high in reliability and convenient to use, has the advantages of effectively and quickly detecting the wear condition of the cutter, reducing the time for checking and replacing the cutter and improving the construction efficiency, and is widely applied in the shield machine industry.
Description
Technical field
The present invention relates to constructing tunnel and use the shield machine parts, relate in particular to the abrasion detection of shield machine with changeable cutting tool.
Background technology
Shield machine is a kind of special engineering machinery of tunnel piercing.The front portion of existing shield machine mainly contains: the cutterhead of forefront, the anterior shield otch ring at cutterhead rear portion and again after Tu Cang etc.Scraper, hobboing cutter, the multiple cutters such as replaceable cutter in advance of cutter and replacement hobboing cutter in advance are installed on the cutterhead, and the perforate on the cutterhead forms slag inlet.During work, the cutterhead rotation, under the rotation of cutterhead drove, the various cutters that are installed on the cutterhead were accomplished the excavation cutting to the soil body.The soil body that cuts, the Tu Cang through entering anterior shield otch ring of the slag inlet on the cutterhead and rear portion thereof carries backward again.
In construction period maintenance knife disc tool process; The changeable cutting tool that needs to be contained in the girff is dismantled taking-up inspection abrasion condition one by one, and the cutter that therefore need not change in a large number needs repeated removal to install, and causes the length that expends time in; Workload is big, and overhaul efficiency is low; Thereby influence the overall progress of constructing tunnel.
Summary of the invention
The pick-up unit that the purpose of this invention is to provide a kind of changeable cutting tool wear information.It can effectively detect the abrasion condition of cutter efficiently, reduces the time that cutter is changed in inspection, improves operating efficiency; And it is simple in structure, and is with low cost, and reliability is high, and is easy to use.
The present invention realizes its goal of the invention; The technical scheme that is adopted is: a kind of pick-up unit of changeable cutting tool wear information; Its design feature is: on changeable cutting tool knife rest 2 and cutter head 4, offer cylinder blind hole 7; Two blocks at cutter head two ends alloys 5 of cylinder blind hole 7, between 6, cylinder blind hole 7 top square head top surface have a coverage.
Beneficial effect compared with prior art of the present invention is: this device does not receive the influence in cutter path and space, can be installed on the replaceable cutter of the interior girff of any track on the cutterhead panel.When shield machine normally opens a position maintenance during knife disc tool, the cylinder blind hole of the UNICOM that is provided with through replaceable cutter cutter hub cutter head two ends can make things convenient for and judge the tool wear situation intuitively; When wearing and tearing appearred in cutter head, the cylinder blind hole of cutter head sealed end will be worn through, and whether can judge cutter intuitively through the cylinder blind hole at inspection cutter head two ends needs to change.Through above method, can find out the replaceable cutter that has worn and torn accurately, have practical, fitting operation is convenient, abrasion detection is accurate and simple in structure, the advantage that cost is low.
Description of drawings
Figure of description is a synoptic diagram of the present invention.Fig. 1 is a front view, and Fig. 2 is a left view, and 1 among the figure is girff, the 2nd, and knife rest, the 3rd, the wedge assembly, the 4th, cutter head, 5 and 6 is wimet, the 7th, cylinder blind hole, the 8th, cutter shaft, the 9th, plug.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated.
Like Fig. 1, shown in 2.The replaceable cutter wear detector of a kind of shield structure; Whole device is made up of inspection knife rest 2, cutter head 4, plug 9; Cutter head 4 and knife rest 2 are connected through welding manner, the cylinder blind hole of two appropriate depth of processing on cutter head 4 and knife rest 2, and the blind hole sealed end is on the cutter head between wimet 5 and the wimet 6; On the cylinder blind hole of knife rest end, be provided with plug 9, knife rest is fixed in the girff of cutterhead panel through cutter shaft 8 and wedge assembly 3.
The principle of work of device is that when opening a position the maintenance cutter, whether worn out, judge whether the wearing and tearing of cutter overstep the extreme limit if measuring cutter head two ends blind hole according to cubing; Conveniently find out the cutter that excessive wear need be changed.
Claims (3)
1. replaceable cutter wear detector of shield structure; Whole device is made up of inspection knife rest 2, cutter head 4, plug 9; Cutter head 4 and knife rest 2 are connected through welding manner, the cylinder blind hole 7 of two appropriate depth of processing on cutter head 4 and knife rest 2, and cylinder blind hole 7 sealed ends are on the cutter head between wimet 5 and the wimet 6; On the cylindrical hole of knife rest end, be provided with plug 9, knife rest is fixed in the girff of cutterhead panel through cutter shaft 8 and wedge assembly 3.
2. the replaceable cutter wear detector of shield machine according to claim 1; It is characterized in that: the principle of work of said device is; Wear extent according to replaceable cutter; Whether the cylinder blind hole 7 of two appropriate depth of processing is worn out through judging cylinder blind hole 7 on cutter head 4 and knife rest 2, judges whether the wearing and tearing of replaceable cutter overstep the extreme limit.
3. the replaceable cutter wear detector of shield machine according to claim 1; It is characterized in that: the method for work of said device is; Can be installed on the replaceable cutter in the girff on any track on the cutterhead panel 1, it is every the abrasion condition of cutter that pick-up unit can be reflected.
