Various modifications or alterations are carried out under spirit of the invention.
Fig. 1 is that original structure schematic diagram, Fig. 2 of the large circle of the cutter head of shield machine of the embodiment of the present invention are implementation of the present invention
Structural schematic diagram after the abrasion of the large circle of the cutter head of shield machine of example.The large circle 1 of cutter head of shield machine uses width 360mm,
With a thickness of the doughnut-shaped steel plate of 100mm.The close cutter head of shield machine of the periphery and large circle 1 of the large circle 1 of cutter head of shield machine
It meets native side C and has been covered each by a circle original antifriction alloy plate 11, the corner for meeting native side and periphery to the close cutterhead of large circle
Carry out wear Protection.Former antifriction alloy plate 11 is the Wear-Resistant Compound Steel Plate of 25mm thickness.In shield machine tunneling process, former resistance to adjustment
Golden plate 11 is worn, or even injures the base material of large circle 1, so that abrasion is formed along large circle 1 on the periphery of large circle 1
Cyclic direction groove A.The step of Fig. 3 to Fig. 6 is the restorative procedure of the cutter head of shield machine large circle of the embodiment of the present invention is shown
It is intended to.
Referring to figs. 1 to shown in Fig. 6, the present invention provides a kind of restorative procedure of cutter head of shield machine large circle, including it is following
Step:.
S1, former antifriction alloy plate 11 on the periphery of large circle 1 is cut off, so that the periphery of large circle 1 is exposed outside.
In tunneling process, the former antifriction alloy plate 11 on the periphery of large circle 1 is worn, together with the mother of large circle
Material is worn the formation groove A on the periphery of large circle.As shown in figure 3, by the periphery that cuts off large circle 1
Base material (i.e. the periphery of large circle 1) of the former antifriction alloy plate 11 of abrasion up to large circle 1.
S2, the groove A on the periphery of exposed large circle 1 is modified to the socket joint slot B to form interior walls be smooth.
As shown in figure 4, passing through utilization after worn-out former antifriction alloy plate 11 on the periphery for cutting off large circle 1
The groove A that formation is worn on the periphery of large circle 1 finishing is processed into inner wall using turnning and milling or technique for grinding by numerically-controlled machine tool to be put down
Sliding and regular shape socket joint slot.
Specifically, groove finishing is using techniques such as polishing, machine millings.Pass through the groove A for abrasion being formed using numerically-controlled machine tool
Inner wall polishing or turn-milling cutting at interior walls be smooth and the socket joint slot of regular shape.
S3, it provides and repairs item 2, the size for repairing item 2 is adapted with the size of socket joint slot B, will be repaired item 2 and is embedded at socket joint
In slot B.
In the present embodiment, the periphery of large circle be worn the groove to be formed both ends dock and be formed through annular
The groove.
It provides and repairs item 2, it is annular in shape to repair item 2.Item 2 is repaired to be arranged along the cyclic direction of large circle.Repairing item processing
In the process, repairing item 2 includes muti-piece arc panel.Arc panel described in muti-piece, which joins end to end, is spliced to form the reparation item of annular,
Item is repaired for filling up socket joint slot.
In the present embodiment, repairing item includes 6 pieces of arc strips, the equal length of each piece of arc strip.It repairs item 2 and uses riveting
Plugging technique is followed closely to be welded to connect in the large circle 1.Welding hole is opened up on item specifically, repairing, welding hole is filled in after rivet using rivet
It welds, not only repairs the surrounding and large circle firm welding of item, and is also that reparation item and large circle welding is closely knit out of welding hole.
S4, new antifriction alloy plate 12 is provided, new antifriction alloy plate 12 is covered in and is embedded with the large circle 1 for repairing item 2
On periphery, so that the digging diameter of large circle 1 meets design requirement.
Specifically, as shown in fig. 6, provide new antifriction alloy plate 12, the material for repairing item 2 and new antifriction alloy plate 12
Material be adapted.The material of new antifriction alloy plate 12 is identical as the material of former antifriction alloy plate 11.
New antifriction alloy plate 12 is welded on the periphery of large circle by welding equipment, so that new antifriction alloy plate 12 covers
It is placed on the periphery for being embedded with the large circle 1 for repairing item 2, so that the digging diameter of large circle 1 meets design requirement.
The restorative procedure of the cutter head of shield machine large circle of the embodiment of the present invention passes through the antifriction alloy plate of excision abrasion, benefit
It is trimmed to socket joint slot with the annular groove for wearing formation on large circle, is welded in socket joint slot and repairs the circle that item repairs large circle
New antifriction alloy plate is covered on the periphery of large circle after circumferential surface, on the one hand, ensure that the large circle of cutter head of shield machine
Digging diameter it is consistent with design requirement, and in the case that intensity meets construction requirement, on the other hand, reduce the excision of large circle
Amount and post-production amount can reduce rehabilitation cost using new restorative procedure, shorten repair time, can complete shield machine overhaul as early as possible
Work, comes into operation, reduces rehabilitation cost, improves economic benefit.
