Abstract
An installation structure of a trapezoid-shaft fixed hobbing cutter of a shield machine comprises a wedge block, a locking cylinder, a bolt, a hobbing cutter and a cutter box, wherein the bolt, the hobbing cutter and the cutter box are matched with the wedge block and the locking cylinder. The cutter box is cylindrical and connected with a cutter head panel through a flange. A chamfered groove and a load bearing side face are disposed on both sides of the cutter box. Fixed ends of a hobbing cutter shaft are trapezoid, and all corners of the fixed ends of the hobbing cutter shaft are in the shape of filleted corners. The hobbing cutter is inserted in the cutter box, the fixed ends of the cutter shaft at both ends are fixed through the bolt and the wedge block. Two opposite faces of the fixed ends of a hobbing cutter trapezoid shaft respectively correspond to the wedge block and the inner load bearing side face of the cutter box. The bolt penetrates through the wedge block to be in threaded connection with the locking cylinder in a cylindrical installation hole installed on the cutter box. A plurality of reinforcing ribs are disposed between the flange and the cutter box. The cutter box is a hollow cylinder, and the side face of the cutter box is processed into a special-shaped groove. The installation structure of the trapezoid-shaft fixed hobbing cutter of the shield machine is simple and reliable, low in cost and convenient to demount, and improves flexibility of use of the shield machine.
Description
Technical field
The utility model relates to the mounting structure of shield machine cutter, is specifically related to a kind of mounting structure of trapezoidal shaft fixed hobboing cutter.
Background technology
Because general trapezoidal shaft fixed hobboing cutter cutter box is a rectangular configuration, its processing welding capacity reaches, cost is high, and precision is lower, again because quantity is big, makes the whole cost of shield machine occupy high; Though there also have hobboing cutter cutter box to adopt to be cylindrical, other fixed forms are unreasonable, and with bolt hobboing cutter directly are connected on the hobboing cutter cutter box; This mounting structure poor reliability, and dismounting is inconvenient, under abominable working condition; Cause damage easily, influence operating efficiency.
The utility model content
The utility model provides a kind of mounting structure of trapezoidal shaft fixed hobboing cutter, and it is unreasonable to have solved trapezoidal shaft fixed hobboing cutter mounting structure, poor reliability, the problem of dismounting inconvenience.
For realizing above-mentioned purpose, adopt following technical scheme:
The mounting structure of the trapezoidal shaft fixed hobboing cutter of a kind of shield machine comprises wedge, locking cylinder and supporting bolt, hobboing cutter and cutter box, and said cutter box is cylindrical; Its with the cutterhead panel between be connected through flange; And have chamfered groove in cutter box both sides and carry the side, said hobboing cutter cutter shaft fixed end is trapezoidal, Qi Gejiao is rounded shapes; Hobboing cutter is inserted in the cutter box; The cutter shaft fixed end at two ends is fixed through bolt and wedge, and with to carry the side corresponding in wedge and the cutter box, the interior locking cylinder of cylinder installing hole was threaded two opposite faces of the trapezoidal axle of said hobboing cutter fixed end on said bolt passed wedge and is installed in the cutter box respectively.
As a preferred version, between said flange and the cutter box several reinforcing ribs are arranged.
As further preferred version, said cutter box is a hollow cylinder, and special-shaped groove all is processed in the side.
The utility model has replaced original rectangle cutter box with cylindrical hobboing cutter cutter box, has reduced the welding processing amount and has improved precision, has reduced cost; And whole cylinder cutter box passes through secure on cutterhead; Make the cutter box more be prone to standardized production, further reduced cost, and the chamfered groove of this mounting structure through cutter box hollow cylinder etc. assembles; Not only simple and reliable; And convenient disassembly, change the hobboing cutter box of other type or the cutter of going ahead of the rest according to the native condition of difference when more adapting to shield machine renovation afterwards, improve the flexibility of the use of shield machine.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model overall structure front view;
Fig. 2 is the vertical view after Fig. 1 removes cutterhead;
Fig. 3 is the sectional view of Fig. 2 at the A-A place.
Among the figure:
1, wedge; 2, chamfered groove; 3, reinforcing rib; 4, locking cylinder; 5, carry the bottom surface; 6, hobboing cutter; 7, cutterhead panel; 8, cutter shaft fixed end; 9, special-shaped groove; 10, mounting flange; 11, fitting recess; 12, hobboing cutter cutter box hole; 13, cutter box; 14, cylinder installing hole; 15, bolt; 16, carry the side.
The specific embodiment
Shown in Fig. 1 to 3, provided a specific embodiment of the utility model, among the figure; Comprise wedge 1, locking cylinder 4 and supporting bolt 15, hobboing cutter 6, cutter box 13 etc.; The cutter shaft fixed end 8 of said hobboing cutter 6 is the trapezoidal of rounded shapes for each angle, and said cutter box 13 is a flange cylindrical knife box, and its main body is a hollow cylinder; Mounting flange 10 is arranged on the cutter box panel 7; Cutter box 13 is connected through mounting flange 10 with cutterhead panel 7, and in the flange 10 and the cutter box outside reinforcing rib 3 is arranged, and increases bonding strength; Respectively there is a chamfered groove 2 at the fitting recess 11 side two ends of cutter box 13 and carries bottom surface 5, carry side 16, and the every side in the top of hollow cylinder is opened fitting recess 11, and each carries side 16 and all processes special-shaped groove 9.Its mounting means is that hobboing cutter 6 is inserted in the cylindrical knife box 13 from the top; Wedge 1 is installed then; One face contacts with cutter shaft fixed end 8 trapezoidal faces; Another plane contacts with cutter box 13, the hole that bolt 15 passes wedge 1 be installed in cutter box 13 on locking cylinders 4 in the cylinder installing hole 14 be threaded, realizes the fixed installation of trapezoidal hobboing cutter.
The utility model has replaced original rectangle cutter box with cylindrical hobboing cutter cutter box, has reduced the welding processing amount and has improved precision, has reduced cost; And whole cylinder cutter box passes through secure on cutterhead; Make the cutter box more be prone to standardized production, further reduced cost, and the chamfered groove of this mounting structure through cutter box hollow cylinder etc. assembles; Not only simple and reliable; And convenient disassembly, change the hobboing cutter box of other type or the cutter of going ahead of the rest according to the native condition of difference when more adapting to shield machine renovation afterwards, improve the flexibility of the use of shield machine.
