Abstract
The utility model discloses an installation structure of a hexagonal shaft seat fixed pilot cutter for a shield machine in a cylindrical cutter box. The installation structure comprises a cylindrical pilot cutter, the cylindrical cutter box and a transitional cutter box, wherein the pilot cutter and a fixed check block are arranged in the transitional cutter box with a hexagonal fixed shaft by a shaft sleeve; and the transitional cutter box and a locking cylinder are arranged in the cylindrical cutter box by a wedge-shaped block. By the installation structure, a cutter changing method is optimized, and the pilot cutter is replaced only by disassembling simple connection between the pilot cutter and the transitional cutter box, so that the cutter box can be used circularly, and the problems of complex manufacturing and high cost due to the welding connection of the pilot cutter and the transitional cutter box are solved.
Description
Technical field
The utility model relates to a kind of shield machine cylinder cutter mounting structure of going ahead of the rest, and the fixed cutter in advance of particularly a kind of shield machine hexagon axle bed is at the mounting structure of cylinder cutter box.
Background technology
The fixed existing cutter of hexagon axle bed is used very many, but general cutter cutter box in advance, but the cutter of will going ahead of the rest directly is welded in hexagon fixedly on the axle bed, and welding is made complicated, and replacings needs integral replacing, so cost is high, changes inconvenience, keeps in repair difficult especially.
The utility model content
The purpose of the utility model provides the mounting structure of the fixed in advance cutter of a kind of shield machine hexagon axle bed at cylinder cutter box, has solved the cylinder cutter installing/dismounting inconvenience of going ahead of the rest, the problem that installation cost is high.
For realizing above-mentioned purpose, adopt following technical scheme:
The fixed cutter in advance of a kind of shield machine hexagon axle bed is at the mounting structure of cylinder cutter box; Comprise cutterhead, cutter box and cutter is integrated in advance, the hexagon axle head that stretch out at said cutter box two ends is fixed on the tool rest, and said in advance cutter is integrated inserts in the cylindrical hobboing cutter box from last or below; Said cutter box two ends respectively are fixed with a pair of wedge; Fixing hole is arranged on it, and screwed cylindrical piece passes movable wedge and stationary wedge piece, and is tightened in the cylindrical screwed hole of locking.
As a preferred version, said tool rest is a hollow cylinder, and itself and cutter head of shield machine are welded as a whole.
As further preferred version, said stationary wedge block welding is fixed on cutter box side.
The cutter box of the utility model is cylindrical and do not have any fixing hole, and welding capacity is few, and is easy to process, and cutter can be through 2 bolton at existing cutter box in advance; Processing with time slot is also very simple, both can adorn hobboing cutter, can adorn cutter in advance again; When needs use in advance cutter, with cutter in advance integrated through wedge, bolt etc. be locked in the hobboing cutter cutter box, so the utility model is simple in structure; Self-locking performance is good, and convenient disassembly has improved efficiency of construction; Reduce the cutterhead welding capacity, reduced cost.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 removes the overall structure vertical view of cutterhead for the utility model;
Fig. 2 is the B-B place sectional view shown in Fig. 1;
Fig. 3 is integrated in the scheme of installation of B-B position for the cutter of going ahead of the rest;
Fig. 4 is the vertical view of cutter in the cutter box of going ahead of the rest;
Fig. 5 is the sectional view at A-A place among Fig. 4.
Among the figure:
1, cutter box; 2, cutter is integrated in advance; 3, set bolt; 4, chamfered groove; 5, lock bolt; 6, locking hole; 7, cutterhead panel; 8, wedge; 9, locking cylinder; 10, reinforcing rib; 11, cutter in advance; 12, fixed wedge.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the utility model through embodiment.
Shown in Fig. 1 to 5, the fixed cutter in advance of the described shield machine hexagon of the utility model axle bed has cutter 11 in advance at the mounting structure of cylinder cutter box in advance on the cutter integrated 2; Cutter box 1 is a hollow cylinder, the screwed hole that has no on the cutter box 1, and cutter box 1 welds together with cutterhead panel 7; In cutter box 1 both sides a pair of fixed wedge 12 is arranged respectively; Itself and cutter box 1 weld together, and on the fixed wedge 12 locking hole 6 are arranged, and have on the cutter box 1 to carry the chamfered groove 4 of cutter integrated 2 in advance; The left and right sides end cap of cutter integrated 2 is hexagon in advance; The mounting means of cutter integrated 2 inserts in the cutter box 1 from last or below for the cutter integrated 2 of will going ahead of the rest in advance; Insert cutter box 1 by wedge 8 again; Screwed locking cylinder 9 is inserted in the locking hole 6 on the cutter box, and set bolt 3 passes the locking cylinder 9 in the locking hole 6 on wedge 8 and the fixed wedge 12, and the cutter integrated 2 of will going ahead of the rest is fixed in the cutter box 1; This kind fixed structure makes that in advance cutter integrated 2 can self-locking, and stable being fixed on the cutter box 1.
The cutter box of the utility model is cylindrical and do not have any fixing hole, and welding capacity is few, and is easy to process, and cutter can be fastened on the cutter box 1 through lock bolt 5 in advance; The processing of groove is very simple, both can adorn hobboing cutter, can adorn cutter cutter box in advance again, when cutter is gone ahead of the rest in the needs use; With cutter in advance integrated through wedge, bolt etc. be locked in the hobboing cutter cutter box,, so the utility model is simple in structure, self-locking performance is good; Convenient disassembly has improved efficiency of construction, has reduced the cutterhead welding capacity, has reduced cost.
