Abstract

The invention discloses a mounting structure of a preceding knife box for a shield machine. The mounting structure comprises a knife flywheel bracket, a preceding knife integration, a knife plane and a knife box, wherein two transversely-arranged holes are respectively arranged at two ends of the knife box; the knife box is arranged on the knife plane on the knife flywheel bracket; the preceding knife integration is arranged in the knife box through a shaft and is self-locked in the knife box by using a baffle and bolts; four cylindrical blocks with threaded holes are inserted in the fixed holes on the knife plane; a wedged block is inserted into a pace between the knife plane and an inner cavity of the knife box and is connected with the cylindrical blocks with the threaded holes through bolts; two fixing wedges with holes are respectively arranged on two surfaces of the knife box in another direction and are correspondingly inserted into the fixed holes on the knife box; and bolts are connected with cylinders with the threaded holes through the two fixing wedges. The mounting structure disclosed by the invention is simple and compact in structure and is easier for mounting, detaching and maintaining and has ensured rigidity of the knife box and improved work efficiency.

Description

The go ahead of the rest mounting structure of cutter cutter box of shield machine

Technical field

The present invention relates to the shield machine engineering machinery field, be specifically related to the go ahead of the rest mounting structure of cutter cutter box of a kind of shield machine.

Background technology

Cutter is the cutter that in advance cuts the soil body in advance, it cut the soil body in advance before the cutting knife cutting soil body, adopt cutter in advance, can significantly increase the flowability of the cutting soil body, reduce the moment of torsion of cutting knife greatly, improve the stock-removing efficiency of cutting knife, reduce the abrasion of cutting knife, on the loose media stratum, especially the go ahead of the rest result of use of cutter of sand-pebble layer is fairly obvious.In the shield-tunneling construction process, the cutter of going ahead of the rest is a vulnerable part, often needs to safeguard and change, and in the common work progress, the operating space of changing cutter is comparatively narrow, be not easy accurately location and fixation of cutter, simultaneously since in operation process cutterhead and the suffered vibrations of cutter bigger, connecting bolt is prone to phenomenons such as loosening, if the tool rest opening degree is excessive, though be easy to change cutter, also can cause the intensity of tool rest bad easilier, cause the damage of cutter and get loose easilier.

Summary of the invention

The invention provides the go ahead of the rest mounting structure of cutter cutter box of a kind of shield machine, solved shield machine go ahead of the rest cutter install insecure, the problem that gets loose easily.

For achieving the above object, by the following technical solutions:

The go ahead of the rest mounting structure of cutter cutter box of a kind of shield machine, comprise cutterhead support, in advance integrated, the tool rest of cutter, cutter box, respectively there is the fixing hole of two lateral arrangement at described cutter box two ends, the cutter box is installed on the tool rest on the cutterhead support, in advance cutter is integrated is installed in the cutter box by axle, is self-locking in the cutter box by baffle plate and bolt, and 4 cylindrical pieces that are threaded the hole insert in the fixing hole on the tool rest, wedge inserts the space of tool rest and cutter box inner chamber, and wedge is connected by bolt with threaded cylindrical piece; Described cutter box respectively has two fixed wedges that have the hole on the other direction two sides, respectively have on the corresponding insertion cutter box in the fixing hole, and bolt is connected by two wedges and cylinder with threaded hole.

The present invention is simple in structure, compact, adopt cylinder with threaded hole to be connected to come the tool setting box and the cutter of going ahead of the rest to fix by bolt with wedge, not only increased the rigidity of cutter box, and small column with threaded hole, when changing cutter head, can change together with bolt, therefore be easier to install, dismantle and safeguard, improved operating efficiency.

Description of drawings

According to embodiment and accompanying drawing the present invention is described in further detail below.

Fig. 1 is a general structure vertical view of the present invention;

Fig. 2 is Figure 1A-A place sectional view;

Fig. 3 is Figure 1B-B place sectional view;

Fig. 4 is a scheme of installation in the space of cutter cutter box 10 in the junction plate 9 of tool rest 5 and tool rest 5 in advance among Fig. 3;

Fig. 5 is cutter cutter box 10 structural representations of going ahead of the rest among Fig. 2.

Among the figure:

1, cutterhead support; 2, cylindrical piece with threaded hole; 3, cutter is integrated in advance; 4, cutter shaft seat; 5 tool rests; 6, bolt; 7, wedge; 8, wedge; 9, the junction plate of tool rest; 10, cutter cutter box in advance; 11, fixed wedge; 12, bolt; 13, baffle plate; 14, fixing hole; 15, cutter shaft in advance; 16, cutter in advance.

The specific embodiment

Shown in Fig. 1 to 5, provided a specific embodiment of the present invention, among the figure, comprise cutter box frame 1, in advance integrated 3, the tool rest 5 of cutter, cutter cutter box 10 in advance, wherein tool rest 5 two ends respectively have two fixing holes to be used for the cylindrical piece with threaded hole 2 of packing into, with the fixing hole corresponding section of tool rest 5 other hole is arranged, make bolt therefrom to pass; Cutter cutter box 10 is installed on the tool rest 5 in advance, cutter integrated 3 is by bolt 12 in advance, cutter 16 in advance, baffle plate 13 is formed, cutter integrated 3 is installed in the cutter box 10 by its cutter shaft 15 of going ahead of the rest in advance, in the fixing hole 14 on the cylindrical piece 2 insertion tool rests 5 with threaded hole and the cutter cutter box 10 of going ahead of the rest, the space that wedge 7 inserts cutter shaft seat 4 and tool rest 5 inner chambers, wedge 7 is connected by bolt 6 with threaded cylindrical piece 2, respectively there are two fixed wedges 11 that have fixing hole on two sides at the cutter cutter box 10 of going ahead of the rest, fixed wedge 11 and cutter box processing or integrally welded respectively has corresponding cylindrical piece 2 with threaded hole to insert in the fixing hole of fixed wedges 11 and is connected by bolt 6 with two wedges that cooperate with fixed wedge 11 sub 8.

The present invention when mounted, earlier with the square cutter shaft seat 4 of cutter box 10 pack into the headspace of tool rest 5 of horizontal positioned on one side, the width of square cutter shaft seat 4 that is the cutter box 10 that 45 degree tilt this moment is almost just less than the headspace passage of tool rest 5, the square cutter shaft seat 4 that is the cutter box 10 that 45 degree tilt square cutter shaft seat 4 when entering tool rest 5 headspaces central can rotate 45 ° and do not interfere with other wall, square then cutter shaft seat 4 is fitted with inner chamber one wall of tool rest 5 headspaces, the cylindrical piece 2 that is threaded the hole is inserted in the fixing hole in the tool rests 5, wedge 7 is inserted the space of square cutter shaft seat and the formation of tool rest 5 inner chambers one wall, with Bolt Connection wedge 7 and small column, make cutter shaft seat 4 fixing.

The present invention is simple in structure, compact, adopt cylinder with threaded hole to be connected to come the tool setting box and the cutter of going ahead of the rest to fix by bolt with wedge, but also reduced the opening degree of tool rest headspace, increased cutter cassette holder rigidity, and small column with threaded hole, when changing cutter head, can change together, therefore be easier to install, dismantle and safeguard, improve operating efficiency with bolt.
