Abstract

The utility model discloses a mounting structure of a shield machine pilot cutter box, which comprises a cutter head bracket, a pilot cutter integration, a cutter holder and a cutter box. Two laterally arranged fixing holes are respectively arranged in two ends of the cutter box; the cutter box is installed on the cutter holder on the cutter head bracket; the pilot cutter integration is installed in the cutter box through a shaft and locked in the cutter box through a baffle and bolts; four cylindrical blocks with threaded holes are inserted into the fixing holes in the cutter holder; wedge blocks are inserted into the space of the cutter holder and the cavity of the cutter box; the wedge blocks are connected with the cylindrical blocks with the threaded holes by bolts; two fixing wedges with holes are respectively arranged on two sides in the other direction of the cutter box, and are correspondingly inserted into the fixing holes in the cutter box; and the bolts are connected with the four cylindrical blocks with threaded holes through two inclined wedges. The mounting structure is simple and compact, not only improves the rigidity of the cutter box, but also is easier to install, disassemble and maintain, and improves the operating efficiency.

Description

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

Technical field

The utility model relates to the shield machine engineering machinery field, is 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, and 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, cutter is a vulnerable part in advance, often needs to safeguard and change; And in the common work progress, the operating space of changing cutter is comparatively narrow, is 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 more easily, cause the damage of cutter more easily and get loose.

The utility model content

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

For realizing above-mentioned purpose, adopt following technical scheme:

The go ahead of the rest mounting structure of cutter cutter box of a kind of shield machine comprises cutterhead support, integrated, the tool rest of cutter, cutter box in advance, and respectively there is the fixing hole of two lateral arrangement at said cutter box two ends; The cutter box is installed on the tool rest on the cutterhead support; Cutter is integrated in advance is installed in the cutter box through 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 through bolt with threaded cylindrical piece; Said 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 with cylinder with threaded hole through two wedges.

The utility model 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 through bolt with wedge; Not only having 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 utility model is done further explain below.

Fig. 1 is the utility model general structure vertical view;

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. 3.

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 utility model; 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 made up of bolt 12, the cutter 16 of going ahead of the rest, baffle plate 13 in advance; Cutter integrated 3 is installed in the cutter box 10 through 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 through bolt 6 with threaded cylindrical piece 2, on the two sides of the cutter cutter box 10 of going ahead of the rest two fixed wedges 11 that have fixing hole is arranged respectively; Fixed wedge 11 and cutter box processing or integrally welded respectively have corresponding cylindrical piece 2 with threaded hole to insert in the fixing hole of fixed wedges 11 and are connected through bolt 6 with two wedges that cooperate with fixed wedge 11 sub 8.

The utility model 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 getting into 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, in the fixing hole in the cylindrical piece that the is threaded the hole 2 insertion tool rests 5, wedge 7 is inserted the space of square cutter shaft seats 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 utility model 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 through bolt, but also reduced the opening degree of tool rest headspace, increased cutter cassette holder rigidity with wedge; 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.
